The embodiment of the present disclosure discloses a hose telescopic device with a locking structure, as shown inFIGS.1-8, including: a hose1, a receiving assembly2and a locking structure3, wherein one end of the hose1is received in the receiving assembly2, and the other end of the hose1passes through the receiving assembly2and the locking structure3successively, and the locking structure3includes a locking seat31, the locking seat31being provided with several locking pawls311having elasticity, the locking pawls311being used for locking the hose1, and the locking seat31being sheathed with a locking piece32used for tightening or loosening the locking pawls311.

It should be noted that the locking seat31is sheathed with a locking piece32for tightening or loosening the locking pawls311, and the locking pawls311lock the hose1, to provide a hose telescopic device with a locking structure, which is convenient for locking the hose1after drawing, and expands the scope of application for drawing hose1.

As shown inFIGS.2,3,4and8, the locking piece32includes a locking ring321, the locking ring321being provided therein with locking latches322adapted to the locking pawls311. In a specific implementation, the number of the locking pawls311is set to be plural, a plurality of the locking pawls311are equally spaced along the circumferential direction of the locking seat31, the number of the locking latches322is set to be plural, and a plurality of the locking latches322are equally spaced along the circumferential direction of the locking ring321. It should be noted that the locking pawls311are pressed by the locking latches322, and the locking pawls311are retracted inward to clamp the hose1.

As shown inFIGS.2,3,4and8, the locking pawls311are provided with a first ramp3111and the locking latches322are provided with a second ramp3221adapted to the first ramp3111. It should be noted that the provision of the first ramp3111and the second ramp3221facilitates the pressing of the locking pawls311when the locking piece32rotates, so that the locking pawls311are retracted inward to clamp the hose1.

As shown inFIGS.2,3,4and8, the locking ring321is provided with a shift lever323for conveniently shifting the locking ring321for rotation. It should be noted that the provision of the shift lever323facilitates the rotation of the locking piece32by the user, saving manpower and facilitating the operation.

As shown inFIG.8, the shift lever323is integrally formed with the locking ring321. It should be noted that since the shift lever323is integrally formed with the locking ring321, the structure of the locking piece32is more stable.

As shown inFIGS.2-4, the locking structure3further includes a ferrule33sleeved on the locking seat31, the ferrule33being used for clamping and limiting the locking seat31. It should be noted that the ferrule33serves as a stopper for preventing the locking piece32from being separated from the locking seat31.

As shown inFIGS.2-4, the locking seat31is screwed with a fastening seat34for fastening the locking structure3. It should be noted that the fastening seat34serves a mounting function for fixing the locking structure3in a certain position.

As shown inFIGS.2-4, the locking seat31is sheathed with a wear ring35abutting against the locking piece32. It should be noted that the wear ring35serves a wear resistance function for facilitating the rotation of the locking piece32and preventing the locking piece32from wearing the locking seat31.

As shown inFIGS.1,5,6and7, the receiving assembly2includes a receiving plate21, a first box board22and a second box board23, the first box board22being detachably connected to the second box board23, the receiving plate21being rotatably connected to the first box board22and the second box board23, respectively, the hose1being wound around the receiving plate21, and a winding spring24being mounted on one side of the receiving plate21. In a specific implementation, one side of the second box board23is fixedly mounted with an isolating plate28for isolating the winding spring24.

As shown inFIGS.5-7, a plastic card25is rotatably connected to the first box board22, one end of the plastic card25is hooked with a first spring26, the first spring26is fastened to the first box board22by a fastening screw27, the receiving plate21is provided with a latch portion211and a smooth portion212, and the plastic card25is clamped with the latch portion211. In a specific implementation, a decorative plate29for covering the plastic card25, the first spring26and the fastening screw27is mounted on one side of the first box board22.

It should be noted that when one end of the plastic card25is clamped with the latch portion211, the winding spring24is prevented from driving the receiving plate21to rotate; when one end of the plastic card25is located at the smooth portion212, the winding spring24facilitates to drive the receiving plate21to rotate, so that the hose1may be retracted.

Working principle: the locking seat31is sheathed with a locking piece32for tightening or loosening the locking pawls311, and the locking pawls311lock the hose1, to provide a hose telescopic device with a locking structure, which is convenient for locking the hose1after drawing, and expands the scope of application for drawing hose1.

It is to be understood that the above-described embodiments are merely illustrative for clarity and are not restrictive of the embodiments. For a person of ordinary skill in the art, other variations and modifications are possible in the light of the above description. All embodiments need not be, and cannot be, exhaustive herein.
