Description

Technical Field

[0001] This utility model relates to the field of motorcycle anti-theft experimental technology, specifically a clamp for motorcycle anti-theft experiments. Background Technology

[0002] Motorcycle anti-theft testing refers to a systematic test conducted to scientifically evaluate and verify the anti-theft capabilities (such as anti-pry, anti-hacking, and anti-transfer) of motorcycles by simulating real-world theft scenarios and using standardized testing methods to validate the anti-theft performance of motorcycle anti-theft systems, anti-theft devices, or the entire vehicle. Currently, when a motorcycle is in its anti-theft locked state after parking, the front of the motorcycle can only move within a limited range. To test the force exerted on this range of movement, the handlebars or steering wheel need to be clamped to limit the applied rotational force. However, since motorcycles use handlebars or steering wheels, specific clamping tools are required, resulting in insufficient applicability and affecting practical use. Therefore, a motorcycle anti-theft testing clamp that can solve the above-mentioned drawbacks is needed to improve the effectiveness. Utility Model Content

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] To make the objectives, technical solutions and advantages of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0024] Please see Figure 1-4 As shown, this utility model is a clamp for motorcycle anti-theft experiments, comprising:

[0025] The clamping assembly includes a support block 24 and a clamping block 29. Two support blocks 24 are symmetrically arranged. A threaded rod 26 is connected through the middle of the bottom end of the two support blocks 24, and a threaded post 28 is connected through the upper end of the threaded rod 26. The ends of the threaded post 28 are fixed to the lower sides of the clamping block 29. An arc-shaped groove is provided in the middle of the upper end of the clamping block 29. A rotating handwheel 27 is fixedly connected to the bottom end of the threaded rod 26. A positioning groove 210 is provided through the lower part of the inner side of the support block 24.

[0026] The support block 24 provides the structural mounting base, and the threaded rod 26 supports the threaded post 28 for installation. The threaded extension and retraction allows the clamping block 29 to move up and down, and the handlebars are used to complete the clamping and positioning. The screw rotation of the threaded post 28 allows the clamping block 29 to be adjusted at multiple angles. When the clamping block 29 is at a vertical angle to the ground, it can be used to clamp a motorcycle using a handlebar. When the clamping block 29 is at a horizontal angle to the ground, it cooperates with the positioning groove 210 to clamp a motorcycle using a steering wheel. The arc groove is designed to fit the handlebars and steering wheel to ensure the stability of the clamping structure. Rotating the handwheel 27 applies the force required by the screw of the threaded rod 26.

[0027] The clamping assembly also includes a strip groove 21 that passes through one end of the two telescopic columns 18; a locking column 22 is fixed in the middle of the upper end of the support block 24, and the upper part of the locking column 22 extends out of the strip groove 21. Locking nuts 23 are threadedly connected to both the upper and lower ends of the locking column 22.

[0028] The slot 21 receives the locking post 22 and is locked by the upper and lower locking nuts 23, thus fixing the support block 24 to the telescopic rod.

[0029] The middle of the support block 24 is connected to the movable opening 25, and the upper part of the threaded rod 26 extends into the movable opening 25.

[0030] The 25mm movable opening meets the experimental clamping requirements for handlebars and steering wheels.

[0031] Working principle: In the anti-theft experiment of motorcycle, when the motorcycle is using the handlebars, the two handlebars are placed into the movable opening 25 of the support block 24, and the clamping block 29 is adjusted to a perpendicular angle to the ground by rotating the threaded column 28. Then, by rotating the handwheel 27, a rotational force is applied to the threaded rod 26. The clamping block 29 is gradually moved upward by the spiral extension and retraction of the threaded rod 26 until the upper arc surface of the clamping block 29 is in close contact with the handlebars. When the motorcycle is using the steering wheel, the clamping block 29 is also adjusted to a horizontal angle to the ground by rotating the threaded column 28. At this time, the clamping block 29 is used in conjunction with the positioning groove 210 to be in close contact with the surface of the steering wheel.

[0032] This solution utilizes the threaded rotation of the clamping block 29 to position and clamp motorcycles with handlebars and steering wheels, facilitating the application of subsequent forces to test the range of motion of the front of the motorcycle after theft prevention. It eliminates the need to replace corresponding structural tools, saving time and effort, and is simple and convenient, significantly improving work efficiency and reducing operating costs.

[0033] Please see Figure 1-4 As shown, this embodiment is based on the above embodiment:

[0034] An adjustable connection assembly includes telescopic columns 18; two telescopic columns 18 are symmetrically arranged.

[0035] The adjustable connection assembly also includes a cross-hole post 11; a fixed post 17 is threadedly connected to one side of the lower opening of the cross-hole post 11, one end of the fixed post 17 is threadedly connected to the other end of a telescopic post 18, and the other side of the lower opening is threadedly connected to the other end of another telescopic post 18.

[0036] The cross-hole post 11 provides a structural mounting base. The lower opening accommodates the installation of the fixed post 17 and a telescopic post 18. The upper opening can be connected to an external power shaft to provide the power required for the experiment. The telescopic post 18 adjusts the support block 24 by extending and retracting through the threads in the cross-hole post 11 and the fixed post 17.

[0037] The middle and lower parts of the outer surface of the cross-hole post 11 are respectively threaded with an upper threaded ring 12 and a lower threaded ring 13. An upper adjusting rod 14 and a lower adjusting rod 15 are respectively fixed on one side of the outer surface of the upper threaded ring 12 and the lower threaded ring 13. A threaded tube 16 is fixed on the inner side of the upper adjusting rod 14 and the lower adjusting rod 15.

[0038] The upper threaded ring 12 and the lower threaded ring 13 respectively satisfy the installation and fixation of the upper adjusting rod 14 and the lower adjusting rod 15. Then the threaded tube 16 is installed. With the help of the threaded rotation, the threaded tube 16 can be connected to the telescopic column 18, which satisfies the experiment of using a steering wheel motorcycle.

[0039] The length of the upper adjusting rod 14 is set to be less than the length of the lower adjusting rod 15.

[0040] The inner diameter of the threaded tube 16 is larger than the outer diameter of the telescopic column 18, and the middle part of the threaded tube 16 and the middle part of one end of the telescopic column 18 are threadedly connected to the locking column 22.

[0041] Working principle: In the above-mentioned motorcycle clamping experiment, when clamping a motorcycle with handlebars, two telescopic columns 18 are threaded into the fixed column 17 and the cross-hole column 11 respectively. The locking column 22, in conjunction with the slot 21 and the locking nut 23, completes the installation of the telescopic column 18 and the support block 24, that is, the support block 24 and the telescopic column 18 are at a perpendicular angle. When clamping a motorcycle with a steering wheel, one telescopic column 18 directly connected to the cross-hole column 11 is removed, and the upper threaded ring 12 and the lower threaded ring 13 are rotated in sequence. Then, two more telescopic columns 18 are threaded into the two threaded tubes 16 respectively, that is, three telescopic columns 18 are equidistantly arranged on the cross-hole column 11. The locking column 22 is then threaded into the slot 21 on the three telescopic columns 18. At this time, the support block 24 and the telescopic column 18 are also at a perpendicular angle, and the internal space of the slot 21 is used to move the position to ensure the required positioning.

[0042] This solution can be adapted to the installation of the support block 24 under different clamping conditions, which is simple and convenient and further improves the usage effect.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
