DETAILED DESCRIPTION OF THE EMBODIMENTS

The following will describe the technical solutions in the embodiments of the present application clearly and completely, in conjunction with the accompanying drawings of the embodiments of the present application. The described embodiments are only a part of the embodiments of the present application, not all of them. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

Please refer toFIGS.1-8, a rolling measuring instrument is provided, comprising a main body100of the measuring instrument. The main body100further includes a housing10, a display screen20, a clamping component30, and a roller arm40. The housing10comprises a cover plate101and a bottom shell102that are mutually matched and connected. The bottom shell102is assembled with a pivot seat104on one side. The display screen20engages with the pivot seat104and can rotate relative to the housing10. One end of the roller arm40is rotatably connected to the bottom shell102, and the other end is rotatably connected to a measuring wheel401. The housing10is connected to a connecting member103through a pin shaft, and the clamping component30is assembled on the connecting member103. The object is measured by the roller arm40, and the roller arm is secured and placed in the housing10to prevent it from frequently falling out and affecting the product's lifespan by the cooperation of magnets. The display screen20can rotate relative to the housing10for easy observation of data by the operator, achieved through the cooperation of the pivot seat104and the stopper201. The pivot seat104and the stopper201are equipped with meshing teeth, enabling the display screen to rotate at angles of 0°, 30°, 60°, and 90°, providing greater adaptability. The setting of the clamping component30facilitates the fixation of the rolling measuring instrument, making it convenient to use. The overall structure is optimized for greater convenience.

In this embodiment, the bottom shell102further includes a clamping plate1021facing the clamping component30, and the clamping plate1021integrally forms a fixing member1022. The clamping plate1021is uniformly provided with multiple slot holes10211. By uniformly arranging the slot holes10211, the friction force of the clamping part is increased, effectively enhancing the clamping force and preventing the rolling measuring instrument from falling off.

In this embodiment, the bottom shell102is also provided with an installation area1023, which is an embedded structure. One side of the installation area1023is equipped with a cavity for assembling the pivot seat104. The lower end of the installation area1023is formed with an installation pillar for assembling the roller arm40. The pivot seat104is inserted into the cavity of the installation area1023and fixed to the installation area1023with screws.

In this embodiment, the display screen20has two through-holes on the side facing the housing10. The display screen20is fixed with a stopper201by screws. One end of the stopper201is equipped with meshing teeth, which engage with the through-hole of the display screen20and the pivot seat104. The setting of the meshing teeth allows the stopper201and the pivot seat104to be fixed at angles of 0°, 30°, 60°, and 90°, facilitating the observation by the operator.

In this embodiment, one end of the roller arm40is equipped with a circular hole and is fitted on the outside of the installation pillar. The roller arm40is assembled to the installation pillar with screws. The other end of the roller arm40is rotatably assembled with a measuring wheel401, which is equipped with a capacitive sensor to collect the rolling data of the measuring wheel401. The roller arm40also has a magnet two402. The roller arm40is assembled to the installation pillar and fixed with screws, allowing it to rotate relative to the installation pillar. The measuring wheel401is mounted at the front end of the roller arm40, and the capacitive sensor collects and processes the rolling data.

In this embodiment, the clamping component30includes a pressing plate301and a linkage plate302. The pressing plate301is connected to the connecting member103and the linkage plate302through pin shafts. The linkage plate302is also connected to the fixing piece1022through a pin shaft. The linkage plate302has mounting holes, in which a clamping pillar303is installed. When the pressing plate301is pressed down, the linkage plate302is pushed outward, increasing the distance between the clamping pillar303and the clamping plate1021. When the pressing plate301is released, the linkage plate302returns to its initial position, and the clamping pillar303fixes the object to be measured to the clamping plate1021, completing the fixation of the rolling measuring instrument.

In this embodiment, the linkage plate302is also equipped with a spare hole, which is located in the middle of the clamping pillar303. The clamping pillar303includes a bolt portion fixed in the installation hole and a clamping head portion facing the clamping plate1021. By designing the spare hole, the clamping pillar303can be adjusted according to the shape of the object, making it more versatile. The clamping head portion of the clamping pillar303is made of rubber material, effectively increasing the friction for gripping.

In this embodiment, the cover plate101is equipped with a magnet one1011that attracts the magnet two402. By setting the magnet one1011and the magnet two402, when the roller arm40is converged to the housing10, the two magnets generate attractive force, which is equal to the force of the roller arm40dropping, thereby completing the convergence of the roller arm40.
