Description

Technical Field

[0001] This utility model relates to the field of barrel insertion testing technology, and in particular to a barrel insertion parallelism testing device. Background Technology

[0002] The fork tube, also known as the fork shank, is the outer tube of the fork. As the external structure of the fork, the fork shank contains the travel tube and is responsible for guiding its movement. This allows the fork to remain stable during shock absorption and to extend and retract according to its designed travel, effectively absorbing ground vibrations and providing a comfortable riding experience. During the production of the fork tube, its levelness needs to be tested. A fork tube levelness testing device is a professional device used to check whether the bicycle fork tube is level. The levelness of the bicycle fork tube is crucial to the bicycle's handling performance, stability, and riding safety. If the fork tube is not installed level, it can cause the bicycle to veer off course and become unresponsive during riding, increasing the risk of riding accidents. However, the testing device is prone to damage and malfunction after high-intensity, long-term testing, at which point it must be replaced.

[0003] The existing replacement mechanism consists of screws and nuts. For some simple measuring elements, when replacement is needed, the housing of the measuring device must first be opened. The housing is usually fixed with screws. Use a suitable screwdriver to unscrew the screws, then carefully remove the housing to expose the internal measuring element. Next, disconnect the measuring element from the rest of the device. This may involve unplugging the plug and loosening the terminals. After that, place the new measuring element in the correct position in the device, reconnect the wiring, and finally close the housing and tighten the screws. However, this disassembly method requires tools, is time-consuming and laborious, and long-term use can lead to stripped threads, making the fixation unstable. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a device for detecting the parallelism of the insertion barrel, which aims to improve the existing technology where disassembly requires tools, is time-consuming and laborious, and can lead to stripping of threads and unstable fixation after prolonged use.

[0039] Working principle: When detector 1 needs to be replaced, press the spring block 4 back. At this time, the spring block 4 compresses the spring 7 and deforms, and retracts. Then, the fixing block 16 is taken out with the connecting rod 8. At this time, the spring block 4 leaves the circular hole 9. Then, rotate the screw 12 out of the nut 13. At this time, the screw 12 and the nut 13 leave the connecting rod 14 and the lower fixing cylinder 10. Then, detector 1 can be picked up and installed. Similarly, rotate the screw 12 and the nut 13 back onto the connecting rod 14 and the lower fixing cylinder 10. Then, the fixing block 16 is put back into the upper fixing cylinder 3. At this time, it can be used normally. This realizes that when detector 1 is damaged or malfunctions, it can be quickly disassembled and replaced without delaying or affecting the workflow.

[0040] When it is necessary to raise or lower the threaded sleeve 19, crank the hand crank 201. At this time, the hand crank 201 drives the worm gear 202 to rotate, and the worm gear 202 drives the worm wheel 203 to rotate. The worm wheel 203 drives the rotating shaft 204 to rotate, and then the rotating shaft 204 drives the threaded rod 205 to rotate. Then the threaded rod 205 rotates the threaded sleeve 206 up and down, thus achieving the effect of adjusting the height of the threaded sleeve 19 according to the needs.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
