The connecting end part142of the elastic piece14is movably connected to the elastic piece connecting part111.

The base plate15of this embodiment is a circuit board. The test strip connector10comprises a plurality of terminals104. One end of the terminals104is electrically connected to the base plate15. The other end of the terminals104is disposed in the test strip accommodating space102. When the test strip2is inserted into the test strip accommodating space102of the test strip connector10, the test strip connecting end part21of the test strip2is connected to the terminals104disposed in the test strip accommodating space102. In this way, the detection circuit of the base plate15can detect the samples at the sampling end part22.

The detecting device of this embodiment further comprises a button16and an outer housing17. The button16is disposed on one side of the elastic piece14away from the connecting end part142and is disposed on one side of the pressing end part143. In this embodiment, the button16is disposed on the pressing end part143and is opposite to the base plate15. The pressing end part143can be pressed by pressing the button16. The outer housing17accommodates the test strip connector10, the sliding block11, the elastomer12, the housing13, the elastic piece14, and the base plate15. The outer housing17comprises a button opening171. The button16is disposed in the button opening171.

Then, the button body161stops moving into the outer housing17. In other words, the limiting cylinder163could limit the moving stroke of the button body161. When the limiting cylinder163is desired to pass through the elastic piece14, it can pass through a retaining hole140provided on the elastic piece14. Thus, the operation of the elastic piece14would not be affected.

FIG. 5is an enlarged view of area B ofFIG. 4.FIG. 6is a combined perspective view of an elastic piece, a base plate, a housing, and a test strip connector of the first embodiment of the present disclosure. As shown in the figure, the elastic piece14of this embodiment comprises an elastic piece body144comprising a first side144aand a second side144bopposite to the first side144a. The second connecting part141is disposed on the elastic piece body144, i.e., on one side between the first side144aand the second side144b. The connecting end part142is connected to the first side144aand is disposed on one side of the elastic piece body144. The pressing end143is connected to the second side144band is disposed on the other side of the elastic piece body144. The first connecting part131of this embodiment comprises two first connecting arms1311oppositely disposed. Each of the first connecting arms1311comprises a connecting hole13111. The second connecting part141comprises two second connecting arms1411oppositely disposed. Each of the second connecting arms1411comprises a connecting shaft14111. The connecting shaft14111of each of the second connecting arms1411is disposed in the connecting hole13111of the corresponding first connecting arm1311. In this way, the first connecting part131can be rotatably connected to the second connecting part141, and the second connecting part141could rotate relative to the first connecting part131. In this embodiment, the second connecting part141of the elastic piece14is assembled to the first connecting part131of the housing13along a direction perpendicular to the second surface152of the base plate15.

The connecting end part142of this embodiment comprises a first connecting piece1421and a second connecting piece1422. The first connecting piece1421is connected to a first side144aof the elastic piece body144. The second connecting piece1422is connected to one side of the first connecting piece1421away from the elastic piece body144and extends in a direction of the test strip accommodating space102. One side of the second connecting piece1422away from the first connecting piece1421is movably connected to the elastic piece connecting part111. One side of the second connecting piece1422of this embodiment away from the first connecting piece1421passes through the second opening153of the base plate15and the first opening132of the housing13and abuts against a sidewall of the elastic piece connecting part111. In this embodiment, an angle A1is defined between the second connecting piece1422and the first connecting piece1421, in which the angle A1is greater than 45 degrees and less than 90 degrees. Meanwhile, the first connecting piece1421and the second connecting piece1422are integrally formed to one piece. The second connecting piece1422could firmly abut against a sidewall of the elastic piece connecting part111of the sliding block11. That is, the force exerted by the second connecting piece1422on the sliding block11is equal to or greater than the elastic force of the elastomer12.

In one embodiment, the connecting end142further comprises a third connecting piece1423connected to the side of the second connecting piece1422away from the first connecting piece1421. When the connecting end part142is connected to the elastic piece connecting part111of the sliding block11, the first connecting piece1421is substantially parallel to the second surface152of the base plate15, and the third connecting piece1423is parallel to the first connecting piece1421. So, the third connecting piece1423abuts against a sidewall of the elastic piece connecting part111. In this embodiment, the third connecting piece1423is perpendicular to a sidewall of the elastic piece connecting part111. The forcing direction of the third connecting piece1423is perpendicular to a sidewall of the elastic piece connecting part111. Before pressing the pressing end part143, the connecting end part142firmly presses against a sidewall of the elastic piece connecting part111. So, the sliding block11is disposed on one side of the test strip accommodating space102away from the test strip insertion hole101.

The pressing end part143of this embodiment comprises a pressing elastic piece1431connected to the second side144bof the elastic piece body144. The pressing elastic piece1431extend toward the button16. One side of the pressing elastic piece1431away from the elastic piece body144is disposed on one side of the button16. In one embodiment, one side of the pressing elastic piece1431away from the elastic piece body144comprises a first bending part1431adisposed on one side of the button16. That is, the first bending part1431ais closer than any other parts to the button16. When the button16is pressed, the button body161would first contact the first bending part1431a. By pressing the first bending part1431a, the pressing elastic piece1431would move in a direction closing to the housing13. The surface of the first bending part1431afacing the button16is arc-shaped, which increases the contact area between the button16and the first bending part1431aand avoid wearing of the pressing elastic piece1431by contacting with the button16.

The elastic piece14of this embodiment further comprises two supporting end parts145. The two supporting end parts145are on the same side as the pressing end part143, which means the supporting end part145is connected to the second side144bof the elastic piece body144. The two supporting end parts145are disposed on two sides of the pressing end part143and is connected to the pressing end part143through the elastic piece body144. That is, the second supporting end part145is not directly connected to the pressing end part143, and the second supporting end part145abuts against the second surface152of the base plate15. When the pressing end part143is pressed by the button16, the pressing end part143moves in a direction toward the base plate15. One end of the two supporting end parts145abutting against the base plate15moves on the second surface152and move in a direction away from the elastic piece body144. The spreading stroke of the supporting end part145is limited to avoid the connecting point between the pressing end part143and the elastic piece body144directly by contacting the base plate15. So, the service life of the elastic piece144can be extended. When stop pressing the pressing end part143, the supporting end part145abuts against one end of the base plate15and moves on the second surface152in a direction closing to the elastic piece body144, which drives the elastic piece14back to the initial position. Thus, the elastic piece14and the button16would perform automatically returning back to the position before the pressing end part143is pressed.

In this embodiment, one end of each supporting end145away from the elastic piece body144abuts against the second surface152of the base plate15. In this embodiment, each supporting end part145comprises a first supporting piece1451and a second supporting piece1452. The first supporting piece1451is connected to the second side144bof the elastic piece body144and extends in a direction away from the base plate15. The second supporting piece1452is connected to one side of the first supporting piece1451away from the elastic piece body144and extends toward the base plate15. One side of the second supporting piece1452away from the first supporting piece1451abuts against the second surface152of the base plate15. The first supporting piece1451and the second supporting piece1452are both integrally formed. An angle is defined between the first supporting piece1451and the second supporting piece1452. The spreading stroke of the first supporting piece1451and the second supporting piece1452is limited by the angle.

In one embodiment, one side of the second supporting piece1452away from the first supporting piece1451comprises a second bending part1452a. The second bending part1452aabuts on the second surface152of the base plate15. The surface of the second bending part1452afacing the base plate15is arc-shaped. In this way, not only the contact area between the second bending part1452aand the base plate15can be increased but the wearing on the second surface152of the base plate15as the second supporting piece1452slides on the second surface152of the base plate15can also be avoided.

In one embodiment, the second surface152of the base plate15comprises a wear-resistant part1521. The second bending part1452aof each second supporting piece1452abuts against the second surface152of the base plate15, preventing the second surface152of the base plate15from wearing as the second bending part1452amoves on the second surface152of the base plate15. The number of wear-resistant part1521in this embodiment is two. The two wear-resistant parts1521are disposed on the second surface152of the base plate15at intervals. Each second bending part1452aabuts against the corresponding wear-resistant part1521. The wear-resistant part1521provides a wear-resistant material on the second surface152of the base plate15.

The configuration of the elastic piece14of this embodiment allows only a slight press on the button16to separate the connecting end part142of the elastic piece14from the elastic piece connecting part111. So, the pressing stroke can be reduced and thereby reducing the overall size of the elastic piece14. The pressed button16can be automatically returned to the initial position before pressing by the automatically returning elastic piece14. Thus, extra restoring mechanism is no longer needed, the overall size and cost can be reduced effectively.

Back toFIG. 2andFIG. 3, the housing13of this embodiment further comprises at least one cushioning elastic piece133. The at least one cushioning elastic piece133is disposed on one side of the first opening132and extends into the first opening132. In this embodiment, the number of cushioning elastic pieces133is two. One end of each cushioning elastic piece133is disposed at one side of the first opening132close to the test strip insertion hole101and extends in a direction away from the test strip insertion hole101. In other words, the cushioning elastic piece133is disposed on the moving path of the sliding block11. The extending direction of the cushioning elastic piece133is parallel to the moving path of the sliding block11. When the connecting end part142is connected to the elastic piece connecting part111, the cushioning elastic piece133abuts against the sliding block11. When the connecting end part142is separated from the elastic piece connecting part111, the elastic force of the elastomer12drives the sliding block11to move toward the test strip insertion hole101. The cushioning elastic piece133first slows down the initial moving speed of the sliding block11, and push the test strip2toward the outside of the test strip connector10at a low speed. In this way, rapid movement of the sliding block11can be avoided to reduce the wearing of the test strip connector10or the test strip2being ejected from the test strip connector10.

In one embodiment, one end of the cushioning elastic piece133abutting against the sliding block11comprises a cushioning bump1331. The cushioning bump1331abuts against the sliding block11to reduce the contact area between the cushioning elastic piece133and the sliding block11, avoiding the cushioning elastic piece133hindering the movement of the sliding block11.

The notch13112communicates with the connecting hole13111and penetrates one side of the first connecting arm1311. The second connecting part141also comprises two second connecting arms1411. Each of the second connecting arms1411comprises a connecting shaft14111. When the second connecting arm1411is disposed on the corresponding first connecting arm1311, the connecting shaft14111of the second connecting arm1411is disposed in the connecting hole13111of the corresponding first connecting arm1311through the notch13112. That is, the connecting shaft14111enters the connecting hole13111through the notch13112. The second connecting part141of the elastic piece14of this embodiment is assembled to the first connecting part131of the housing13along a direction parallel to the second surface152of the base plate15. In one embodiment, the width of one end of the notch13112connected to the connecting hole13111is narrower than the diameter of the connecting hole13111and also narrower than the outer diameter of the connecting shaft14111. In this way, the detaching of the connecting shaft14111from the connecting hole13111can be avoided.

In one embodiment, the width of one end of the notch13112away from the connecting hole13111is greater than the width of one end of the notch13112connected to the connecting hole13111. So, the width of the notch13112gradually increases outward starting from the connecting hole13111. The width of one end of the notch13112away from the connecting hole13111is greater than or equal to the outer diameter of the connecting shaft14111. So, the connecting shaft14111could easily enter the notch13112.

When the first connecting part131is connected to the second connecting part141, the two second connecting arms1411are disposed between the two first connecting arms1311, and each of the second connecting arms1411is adjacent to the corresponding first connecting arm1311, forming two sets of adjacent first connecting arm1311and second connecting arm1411. The first connecting hole13113of each of the first connecting arms1311corresponds to the second connecting hole14112of the corresponding second connecting arm1411. Finally, the securing component18passes through each of the first connecting holes13113of the first connecting part131and each of the second connecting holes14112of the second connecting part141. That is, the securing component18passes through the first connecting hole13113of each of the adjacent first connecting arms1311and the second connecting hole14112of each of the adjacent second connecting arms1411, allowing the first connecting part131to be rotatably connected to the second connecting part141.

In one embodiment, the securing component18of this embodiment comprises a securing shaft181. Two ends of the securing shaft181respectively comprise a first stopper1811and a second stopper1812.

In this embodiment, the first stopper1811abuts against an outer surface of the first connecting part131, and the second stopper1812abuts against an inner surface of the second connecting part141. The first stopper1811abuts against an outer surface of one of the two first connecting arms1311. The second stopper1812abuts against an inner surface of one of the two second connecting arms1411. The second connecting arm1411abutted by the second stopper1812is adjacent to the first connecting arm1311abutted by the first stopper1811. In this embodiment, the first stopper1811is a bump, and the second stopper1812is an insertion pin. The second stopper1812can be disposed separately from the securing shaft181to facilitate the assembly of the securing shaft181.

In summary, the present disclosure provides a detecting device. By disposing a sliding block and an elastomer on a test strip connector and by controlling the position of the sliding block by whether a connecting end part of an elastic piece is connected to an elastic connecting part of the sliding block or not, a detecting device can detect the sample on the test strip when the connecting end part of the elastic piece is connected to the elastic connecting part of the sliding block. When the connecting end part of the elastic piece is detached from the elastic connecting part of the sliding block, the sliding block can be pushed by the elastomer to allow automatically returning of the test strip.
