[0036] This utility model provides an overall structural schematic diagram of an embodiment of a speedometer testing device, including:

[0037] Please see Figures 1-6This embodiment of a speedometer testing device includes a body 1. A groove 10 is formed inside the body 1, and a shaft hole 11 is formed on the inner wall of the groove 10. A shaft 20 is inserted into the shaft hole 11, and a clamping rod 21 is installed outside the shaft 20. Two through holes 19 are formed inside the clamping rod 21, through which a pressure rod 17 passes. A clamping plate 18 is installed at the end of the pressure rod 17, and a spring 16 is fixedly connected to the surface of the clamping plate 18. The other end of the spring 16 is fixedly connected to the surface of the clamping rod 21. The surface of the clamping rod 21 has... When the wiring hole 2 of the test device is worn, the concealed handle 22 can be pulled up and the clamp 18 can be pressed. The clamp 21 can be rotated by the shaft 20 and the shaft hole 11 so that the clamp 18 is directly above the wiring plug. At this time, the spring 16 of the clamp 18 is released and the clamp 18 is clamped on the top of the wiring plug, which can secure the wiring plug inside the wiring hole 2. Therefore, when the wiring hole 2 is worn due to repeated insertion and removal, resulting in loose and unstable wiring, the stability of the wiring connection can be effectively improved so as not to affect the staff to test the odometer.

[0038] It is worth noting that, in order to effectively protect the display screen 9 of the testing device, specifically, the main body 1 has a slot 13 inside, a fixing block 14 is installed on the top of the slot 13, a round hole 15 is opened inside the fixing block 14, the round hole 15 communicates with the slot 13, a round rod 25 is movably connected inside the round hole 15, a protective cover 3 is installed on the outside of the round rod 25, a connecting block 23 is installed on the outside of the protective cover 3, a locking block 24 is provided at the bottom of the connecting block 23, and a slot 12 is opened inside the main body 1, the slot 12 engages with the locking block 24.

[0039] Next, in order to facilitate the connection and testing of the odometer, a wiring hole 2 is provided at the bottom of the groove 10. The wiring hole 2 is located directly below the clamping plate 18. The wiring hole 2 structure makes it convenient for users to plug in the wiring to test the odometer.

[0040] Meanwhile, to facilitate users' observation of test data, a display screen 9 is installed on the surface of the main body 1. The display screen 9 is located directly below the protective cover 3. Through the structure of the display screen 9, the test data can be effectively observed and recorded.

[0041] Furthermore, in order to ensure good heat dissipation of the testing device, specifically, the main body 1 has heat dissipation holes 7 inside, and a dustproof mesh 8 is installed inside the heat dissipation holes 7. Through the structure of the heat dissipation holes 7 and the dustproof mesh 8, the testing device can dissipate heat effectively.

[0042] It is worth noting that, in order to facilitate the power supply and operation of the testing device, a power hole 5 is installed on the surface of the main body 1, and a button 4 is provided on the surface of the main body 1. The power hole 5 can effectively supply power to the testing device, and the button 4 has a good structure to control the testing device.

[0043] Finally, to prevent the user from slipping while holding the testing device, the main body 1 has anti-slip grooves 26 on its surface and speaker holes 6 inside. The anti-slip grooves 26 prevent the user from slipping while holding the testing device, and the speaker holes 6 allow the user to hear the control prompts of the testing device.

[0044] Combination Figures 1-6 The speedometer testing device of this embodiment is used in the following specific way:

[0045] 1: According to the actual use, a groove 10 can be opened inside the main body 1, and a shaft hole 11 can be opened on the inner wall of the groove 10. A shaft rod 20 is inserted into the shaft hole 11, and a clamping rod 21 is installed outside the shaft rod 20. Then, a through hole 19 is opened inside the clamping rod 21. There are two through holes 19, and a pressure rod 17 passes through the through hole 19. Then, a clamping plate 18 is installed at the end of the pressure rod 17. A spring 16 is fixedly connected to the surface of the clamping plate 18, and the other end of the spring 16 is fixedly connected to the surface of the clamping rod 21. A concealed handle 22 is opened on the surface of the clamping rod 21.

[0046] 2: When the wiring hole 2 of the test device becomes worn after repeated plugging and unplugging, causing the wiring plug to become loose, the clamping rod 21 can be pulled up by the hidden handle 22, and the clamping plate 18 can be pressed to compress the spring 16 until the clamping rod 21 is rotated 90 degrees by the shaft 20 and shaft hole 11 and is directly above the wiring plug. Then the clamping plate 18 is released, and the rebound force of the spring 16 causes the pressure rod 17 to slide inside the through hole 19, pressing the clamping plate 18 onto the wiring plug, so that the wiring plug is clamped inside the wiring hole 2. In this way, when the wiring hole 2 becomes worn due to repeated plugging and unplugging after long-term use, causing the wiring to become loose, the wiring can be clamped inside the wiring hole 2, which effectively improves the stability of the wiring connection and will not affect the staff to test the odometer.

[0047] 3: Finally, a slot 13 can be made inside the main body 1, and a fixing block 14 is installed on the top of the slot 13. A circular hole 15 is made inside the fixing block 14, which communicates with the slot 13. Then, a circular rod 25 is movably connected inside the circular hole 15. A cover 3 is installed outside the circular rod 25, and a connecting block 23 is installed outside the cover 3. Then, a locking block 24 is provided at the bottom of the connecting block 23. A locking groove 12 is made inside the main body 1, and the locking block 24 is locked inside the locking groove 12. In this way, when using the testing device, the connecting block 23 can be pulled up so that the locking block 24 is no longer locked inside the locking groove 12. Then, the cover can be flipped over by rotating the circular rod 25 inside the circular hole 15. 3. Press the cover 3 until it is vertically above the slot 13, then press the cover 3 to make the round rod 25 slide inside the slot 13. Insert the cover 3 into the slot 13, and you can use the test device and observe the test data through the display screen 9. After use, pinch the connecting block 23 and slowly pull the cover 3 upward until the round rod 25 is inside the round hole 15. Then flip the cover 3 until the card block 24 is engaged inside the card slot 12. At this time, the display screen 9 can be covered and protected. In this way, when the test device is not in use, its display screen 9 has a protective structure to prevent accidental bumps from breaking the display screen 9, and will not affect the staff's observation of test data in subsequent use.
