Abstract
Description
Technical Field
[0001] This utility model relates to the field of testing technology, specifically to a clamping mechanism for fastening a test body and a testing fixture having the same. Background Technology
[0002] X-ray security inspection equipment uses X-rays to scan items and outputs images for inspectors to determine whether prohibited items are being carried. It is widely used in airports, train stations, logistics facilities, and other locations requiring security checks. Whether the performance of X-ray security inspection equipment meets requirements depends on testing the tested items.
[0003] The test subject consists of a backplate and a test card, with the test card mounted on the backplate. For some test items, the backplate is made of ABS plastic sheet with a fixed thickness and dimensions; the dimensions of the ABS plastic backplate do not change with the test content. However, the backplate for the penetration test subject is made of 45# steel plate with fixed dimensions. The thickness of the steel plate backplate varies with the test content, typically between 15mm and 40mm.
[0004] For top-illuminated security scanners, test subjects need to lie flat as they pass through the security lane; while for side-illuminated scanners, they need to stand upright. Currently, due to the lack of a clamping mechanism, existing test subjects cannot be directly passed upright through the security lane. If it is necessary to stand the test subject upright, temporary supports must be placed on both sides, but this method can only tilt the test subject at best, not fully erect it, significantly impacting the testing effectiveness of side-illuminated scanners.

[0039] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0040] like Figure 1-7 As shown, this embodiment of the invention provides a clamping mechanism for fastening a test body. Specifically, as... Figure 1 As shown, the clamping mechanism includes a base plate 3 and a clamping component 2 disposed opposite to each other, the clamping component 2 being disposed on the base plate 3.
[0041] like Figure 2 and Figure 3 As shown, the clamping assembly 2 includes a guide post 28 extending horizontally, opposing pressure blocks 22, and a locking mechanism. The opposing pressure blocks 22 are configured to be sleeved on the guide post 28, and the pressure blocks 22 are slidably connected to the guide post 28. A cavity is formed between the opposing pressure blocks 22 to hold the test body 1.
[0042] The locking mechanism is used to lock the opposing pressure blocks 22 in the horizontal direction when the test body 1 is placed in the cavity, so as to clamp the test body 1 and thus realize the vertical placement of test bodies of different thicknesses.
[0043] Based on the clamping mechanism for fastening the test body provided in the above embodiments, the specific process for fastening the test body is as follows:
[0044] After the user places both ends of the test body 1 into the cavity formed between the opposing pressure blocks 22, the user operates the locking mechanism. The pressure blocks 22 slide on the guide post 28, adjusting the distance between the opposing pressure blocks 22 to clamp the test body 1, thereby achieving the effect of the test body 1 standing stably.
[0045] The clamping mechanism proposed in this embodiment of the invention is highly versatile and can adjust the spacing between the pressure blocks according to the thickness of the back plate to achieve stable clamping of test objects of different thicknesses, so as to facilitate the performance testing of side-illuminated security inspection equipment.
[0046] In one feasible implementation, the locking mechanism includes an adjustment hole 26 extending in a horizontal direction and a fastener 25. The position of the adjusting block 22 in the adjustment hole 26 is adjusted to adjust the distance between the opposing blocks 22. The fastener 25 cooperates with the blocks 22 to lock the opposing blocks 22.
[0047] One feasible implementation method is, for example Figure 4 (a) and Figure 4 As shown in (b), the locking mechanism also includes an adjusting seat 21, on which an adjusting hole 26 is provided. The pressure block 22 is connected to the adjusting seat 21 by a fastener 25. Exemplarily, the upper part of the pressure block 22 is connected to the adjusting seat 21 by a fastener 25.
[0048] Specifically, fastener 25 includes, but is not limited to, fixing screws.
[0049] In one feasible implementation, the guide post 28 is disposed on the adjusting seat 21. For example, the guide post 28 is disposed at the lower part of the pressure block 22. In this case, when the test body 1 is placed in the cavity formed between the opposing pressure blocks 22, the guide post 28 can serve as a support for the test body 1, which not only facilitates the adjustment of the locking mechanism, but also helps to ensure the stable erection of the test body.
[0050] In one feasible implementation, the locking mechanism further includes an adjusting shaft 23 extending horizontally, the adjusting shaft 23 being configured to adjust the position of the pressure block 22 within the adjusting shaft 23 to adjust the distance between the opposing pressure blocks 22. Exemplarily, the lower portion of the pressure block 22 is sleeved outside the adjusting shaft 23.
[0051] One feasible implementation method is, for example Figure 5 As shown, the adjusting shaft 23 is a threaded shaft with opposite thread directions at both ends. The pressure block 22 is connected to the threaded shaft via a thread. Specifically, when it is necessary to adjust the distance between the two pressure blocks 22, the threaded shaft can be rotated. Since the two threads on the threaded shaft have different directions of rotation, they drive the two pressure blocks 22 to move in opposite directions, thereby increasing or decreasing the distance between the two pressure blocks 22, thus enabling the placement of test subjects of different thicknesses.
[0052] In one feasible implementation, the locking mechanism includes a bearing 24, and the end of the adjusting shaft 23 is sleeved on the bearing 24. Exemplarily, the bottom of the adjusting seat 21 has holes at both ends, and bearings 24 are installed in the holes. The two ends of the adjusting shaft 23 are mounted on the bottom of the adjusting seat 21 via corresponding bearings 24. The type of bearing is not limited.
[0053] One feasible implementation method is, for example Figure 7 As shown, the pressure block 22 includes a groove 27, and the pressure block 22 is slidably connected to the guide post 28 through the groove 27. Specifically, the groove 27 of the pressure block 22 is a horizontally arranged strip groove, and the guide post 28 is embedded in the strip groove, so that the pressure block 22 can slide horizontally along the guide post 28. Of course, in other embodiments, the sliding connection between the pressure block 22 and the guide post 28 can be other connection methods. This embodiment does not limit this, and the operator can adjust the connection method according to the actual situation. The number of grooves 27 and guide posts 28 can be one or more. This embodiment does not limit this, and the operator can adjust the number according to the actual situation.
[0054] One feasible implementation method is, for example Figure 6 As shown, a support platform 31 is provided on the substrate 3 to support the test body 1, and can bear relatively heavy test bodies. The support platform 31 is disposed between two clamping components 2 arranged opposite each other.
[0055] This utility model embodiment also provides a testing fixture, including a test body 1 and the above-mentioned clamping mechanism for fastening the test body, wherein the test body 1 is disposed in the clamping mechanism.
[0056] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
