DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0024] Example:

[0025] See also Figure 1-Figure 5 , the utility model provides a technical solution:

[0026] A vehicle towing hook strength test detection device comprises an operating platform 1, a bracket 2 is installed at the bottom of the operating platform 1, a hanger 3 is installed outside the operating platform 1, a hydraulic rod 4 is installed inside the hanger 3, and a clamping assembly 5 is installed on the top of the operating platform 1;

[0027] The clamping assembly 5 is used to fix the bottom of the vehicle towing hook.

[0028] For further information, see Figure 1 , Figure 2 , Figure 3 and Figure 4In this embodiment, the clamping assembly 5 includes an outer frame 501, a telescopic rod 502, a rotating seat 503, a connecting rod 504, a gear 505 and a clamping block 506. The outer frame 501 is installed on the top of the operating table 1, the telescopic rod 502 is installed inside the outer frame 501, the rotating seat 503 is symmetrically installed on the top of the telescopic rod 502, the connecting rod 504 is installed inside the rotating seat 503, the tooth plate 509 is installed on the end of the connecting rod 504 away from the rotating seat 503, and the clamping block 506 is installed on the top of the gear 505. When it is necessary to test the hardness of the automobile towing hook, by placing the tail of the towing hook between the clamping blocks 506, by starting the telescopic rod 502, the telescopic rod 502 is caused to move upward, so that the connecting rod 504 is rotated inside the rotating seat 503, and the gear 505 is driven to rotate at the same time, so that the clamping blocks 506 are close to each other, so that the tail of the towing hook is clamped and fixed, and the distance between the two groups of clamping blocks 506 can also be controlled according to the size of the towing hook.

[0029] Among them, see Figure 1 , Figure 2 , Figure 3 and Figure 4 In this embodiment, a through slot 507 is provided at the top of the outer frame 501, and the clamping block 506 extends to the top of the outer frame 501 through the through slot 507. A serrated plate 508 is installed on the side that the clamping block 506 wants to approach. The through slot 507 limits the two sides of the clamping block 506. Secondly, the clamping blocks 506 are close to each other, and the serrated plates 508 are evenly spaced, so that the anti-slip property is greatly enhanced to prevent detachment during clamping.

[0030] Second, see Figure 1 , Figure 2 , Figure 3 and Figure 4 In this embodiment, a tooth plate 509 is installed at the bottom of the clamping block 506, and the tooth plate 509 is adapted for use with the gear 505. The bottom end of the gear 505 is rotatably connected to the outer frame 501. Through the rotation of the gear 505, a meshing reaction occurs between the gear 505 and the tooth plate 509, so that the tooth plate 509 realizes translational motion driven by the rotational force of the gear 505, thereby realizing the two groups of clamping blocks 506 approaching each other.

[0031] Furthermore, please see Figure 1 , Figure 2 , Figure 3 and Figure 4In this embodiment, a slide bar 510 is symmetrically provided on the outside of the clamping block 506, and a slide groove is provided on the outside of the outer frame 501 at a position corresponding to the slide bar 510. The slide bar 510 slides inside the slide groove, so that when the clamping block 506 makes a translational movement to get closer, the front and rear sides are limited, so that it can complete linear movement, effectively ensuring the stability during translational movement.

[0032] For further information, see Figure 1 , Figure 2 and Figure 3 In this embodiment, a rectangular groove 6 is provided on the top of the operating table 1, and auxiliary grooves are symmetrically provided on the inner side wall of the rectangular groove 6. A slide plate 7 is installed inside the rectangular groove 6. The clamping assembly 5 is slidably connected to the operating table 1 through the slide plate 7. By inserting the slide plate 7 into the rectangular groove 6 and the auxiliary groove, the clamping assembly 5 can be quickly installed when the towing hook needs to be tested.

[0033] For further information, see Figure 1 and Figure 5 In this embodiment, an extension block 8 is installed at the output end of the hydraulic rod 4, a connecting block 9 is installed outside the extension block 8, and a threaded rod 10 is installed between the extension block 8 and the connecting block 9. The earring at the top of the traction hook is placed between the extension block 8 and the connecting block 9, and the threaded rod 10 is inserted into the interior of the extension block 8 and extended to the interior of the earring and the connecting block 9, thereby completing the fixation of the top of the traction hook, and by starting the hydraulic rod 4, the traction hook completes the stretching work.

[0034] In this embodiment, the implementation scenario is specifically as follows: by inserting the slide plate 7 into the rectangular groove 6 and the auxiliary groove, when the traction hook needs to be tested, the clamping assembly 5 is quickly installed, and by placing the tail of the traction hook between the clamping blocks 506, the telescopic rod 502 is started, so that the telescopic rod 502 moves upward, so that the connecting rod 504 rotates inside the rotating seat 503, and at the same time drives the gear 505 to rotate, so that the gear 505 and the toothed plate 509 are meshed, so that the toothed plate 509 is driven by the rotation force of the gear 505. Under the condition that the two groups of clamping blocks 506 are evenly spaced, the translation movement is realized, so that the two groups of clamping blocks 506 are brought close to each other. The equidistant distribution of the serrated plates 508 greatly enhances the anti-slip property, so that the tail of the towing hook can be clamped and fixed. At the same time, the distance between the two groups of clamping blocks 506 can be controlled according to the size of the towing hook. The earring at the top of the towing hook is placed between the extension block 8 and the connecting block 9, and the threaded rod 10 is inserted into the interior of the extension block 8 and extended to the interior of the earring and the connecting block 9, so as to complete the fixation of the top of the towing hook. By starting the hydraulic rod 4, the towing hook completes the stretching work.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
