Detailed implementation manners

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the attached drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Usually, the components of the embodiments of the present invention described and shown in the attached drawings here can be arranged and designed in various different configurations.

[0027] Please refer to Figures 1-8, a test fixture for a test device provided by the present utility model includes a bottom support and two lateral adjustment devices symmetrically arranged on the bottom support.

[0028] Among them, the bottom support provides a support foundation for the entire device, including a support plate 7 and two symmetrically arranged support frames 5. The support plate 7 is a conventional flat plate structure, and the support frame 5 is a rectangular cube structure with several holes opened in the middle to reduce the weight of the entire device. The top of the support frame 5 is connected to the lateral adjustment device.

[0029] One end of the adjacent lateral adjustment devices is provided with a vertical probe for connecting with the test device. A vertical adjustment device is arranged in the middle of the bottom support, and a carrier device is detachably connected to the top of the vertical adjustment device. The top of the carrier device is used to arrange the device under test.

[0030] Adopting the above structure of the present utility model mainly includes a bottom support and two lateral adjustment devices symmetrically arranged on the bottom support. One end of the adjacent lateral adjustment devices is provided with a vertical probe for connecting with the test device. A vertical adjustment device is arranged in the middle of the bottom support, and a carrier device is detachably connected to the top of the vertical adjustment device. During the use process, the carrier device can be detached from the vertical adjustment device to fix the test device, and then the carrier device with the fixed test device is reinstalled on the vertical adjustment device. After adjusting the vertical adjustment device and the lateral adjustment device to the proper position, the test can be carried out. Through the above structure, when setting the test device, there is no restriction of any space, the operable range is large, and the test device can be set quickly, improving the work efficiency.

[0031] In an exemplary embodiment of the present utility model, the lateral adjustment device includes a first adjustment knob 6, a first adjustment gear set, and a moving plate 4. The input end of the adjustment gear set is connected to the first adjustment knob 6, and the bottom of the moving plate 4 is meshed with the bottom of the adjustment gear set to drive the moving plate 4 to move on the top of the support frame 5.

[0032] Among them, the moving plate 4 is a structure with semi-circular arcs at both ends. One end is connected to the fixed block 2, and the other end is used to contact and limit with the support frame 5 when the moving plate 4 moves to prevent the two moving plates 4 from approaching too closely.

[0033] Specifically, a fixed block 2 is arranged on one side of the top of the moving plate 4. There is a pressing plate 1 for setting the probe on the fixed block 2. A radio frequency connector 3 is arranged on the side of the fixed block 2 relative to the probe and is connected to the probe.

[0034] The probe is used to connect with the chip to read data, and the radio frequency connector 3 is used to connect with an external device to transmit the data to an external terminal for data display.

[0035] In an exemplary embodiment of the present utility model, the first adjustment gear set includes a housing 8, a first bevel gear 16, a spur gear 15, and a second bevel gear 17 provided on the first adjustment knob 6. The first bevel gear 16 is meshed and connected with the second bevel gear 17. The first bevel gear 16 and the spur gear 15 are coaxially connected by a connecting shaft, and the connecting shaft is rotatably connected within the housing. The spur gear 15 is meshed and connected with the bottom of the moving plate 4. Wherein, a spur rack can be provided at the bottom of the moving plate 4.

[0036] During use, by rotating the first adjustment knob 6, the second bevel gear 17 rotates, driving the first bevel gear 16 to rotate. The spur gear 15 is driven to rotate through the connecting shaft, and then the moving plate 4 meshed with the spur gear 15 is driven to move horizontally.

[0037] In an exemplary embodiment of the present utility model, the vertical adjustment device includes a second adjustment knob 10, a support column 18, a support block 9, a carrying device, and a second adjustment gear set 19. The support block 9 is connected to the support plate 7. The support column 18 is slidably connected within the support block 9. The second adjustment gear set 19 is provided within the support block 9. Its input end is connected to the second adjustment knob 10, and its output end is connected to the support column 18 through a connecting device for driving the support column 18 to move up and down. The top of the support column 18 is connected to the carrying device.

[0038] Wherein, the connecting device can be a flat plate and a rack. The support column 18 is connected to the flat plate, and a rack is provided under the flat plate and meshed with the output end of the second adjustment gear set 19. The last gear of the output end of the second adjustment gear set 19 is meshed and connected with the rack. Through the output power of the second adjustment gear set 19, the support column 18 is driven to move.

[0039] It should be noted that the second adjustment gear set 19 in this solution is a conventional multi-stage reduction gear combination, and its structure will not be elaborated too much in this solution. A relatively large reduction ratio can be set, which can be specifically set according to the weights of the support column 18 and the carrying device. In this way, self-locking can be formed to prevent reverse output, that is, to prevent reverse output from the output end of the second adjustment gear set 19 to the input end. In this way, no other clamping devices need to be set, and the gravity of the support column 18 and the carrying device will not cause reverse output from the output end of the second adjustment gear set 19 to the input end. Of course, a check valve or other structures can also be set when necessary. In this embodiment, only the simplest structure is proposed. Similarly, for the first adjustment gear set, the selected gears also achieve a reduction tooth ratio that cannot be reversely output from the output end to the input end.

[0040] Specifically, the carrying device includes a carrying platform 11 and limit blocks 12 provided at four corners of the carrying platform 11. A slide rail 13 and a carrying block 14 are provided in the middle of the carrying platform 11. The carrying block 14 is slidably connected to the slide rail 13 and is limited by the slide rail 13.

[0041] Among them, the vehicle device includes a connecting block, a test stage, and a push-pull handle. The test stage is connected to the connecting block, and the push-pull handle is connected to one side of the connecting block. The connecting block is connected to the bearing block 14. Specifically, threaded holes are provided in both the connecting block and the bearing block 14, and the connecting block and the bearing block 14 are detachably connected through the threaded holes and bolts.

[0042] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
