[0004] The above mechanism realizes shielding test on the PCB boards of two mobile phones by setting up two identical independent chambers. However, in actual use, multiple shielding boxes are used for testing at one time to ensure the detection efficiency. Placing multiple shielding boxes inside the test station will cause excessive space to be occupied, and also affect other test processes. Utility Model Content

[0005] The utility model aims to provide a stackable drawer shielding box for product testing, so as to solve the problem in the background art that placing a plurality of shielding boxes inside a test station will occupy too much space.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a drawer shielding box for stacking product testing, comprising a shielding box body and an upper cover plate hinged at the top of the shielding box body, a guide rod is slidably connected inside the shielding box body, a product placement rack is fixedly connected to one side of the guide rod, and a product tooling is fixedly connected to one side of the product placement rack, and spring hooks are provided at both ends of the upper end of the other side of the shielding box body;

[0007] The four corners at the top of the shielding box body are all provided with limiting grooves, and a stacking sealing mechanism is provided inside the limiting groove for sealing the remaining space by using an air bag, and the stacking sealing mechanism includes a limiting block, and the limiting block is fixedly connected to the four corners at the bottom of the shielding box body, and the limiting block and the limiting groove are engaged with each other;

[0008] The upper ends of both sides of the outer side of the shielding box body are both engaged and connected with elastic limiting pieces, and an anti-skid mechanism for increasing the anti-skid and wear-resistant performance of the shielding box bodies when they are stacked is arranged on one side between the elastic limiting pieces.

[0009] Furthermore, a power switch is provided at the middle position of one end of the other side of the shielding box body, an AC socket is provided on the other side of the shielding box body below the power switch, a speed regulating valve is provided on the other side of the shielding box body away from the power switch, a filter assembly is fixedly connected to the other side of the shielding box body close to the AC socket, and a power divider is fixedly connected to the other side of the shielding box body on one side of the filter assembly, and a RF port is provided on the other side of the shielding box body above the filter assembly.

[0010] Furthermore, a second airbag is fixedly connected inside the limiting groove, and a top end of the second airbag is fixedly connected to the first airbag via a hose.

[0011] Furthermore, the top end of the first airbag extends to the outside of the limiting groove, and the inner side of the first airbag is fixedly connected to an elastic layer, and the inner side of the elastic layer is fixedly connected to an anti-slip bump.

[0012] Furthermore, the cross section of the anti-skid protrusions is semicircular, and the anti-skid protrusions are distributed on the inner side of the elastic layer at equal intervals.

[0013] Furthermore, the anti-skid mechanism includes an anti-skid pad, and the anti-skid pad is fixedly connected to one side between the spring hooks, and the top of the anti-skid pad is fixedly connected to a wear-resistant layer.

[0014] Furthermore, both ends of the outer sides of the shielding box body are fixedly connected with clamping blocks, and one side of the elastic limiting piece is provided with a clamping groove matching the clamping block.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. When stacking the shielding box bodies, the basic stacking of the shielding box bodies is achieved by engaging the limiting block into the inside of the limiting groove. However, since the depth and height of the limiting groove and the limiting block when engaged are relatively small, instability is likely to occur after stacking. When engaged, the limiting block applies a squeezing force to the second airbag, so that the gas inside the second airbag is transported to the inside of the first airbag through the hose, thereby expanding the first airbag, and using the expansion of the first airbag to fill the gap generated when the limiting groove and the limiting block are engaged, thereby increasing the stability of the limiting groove and the limiting block when engaged;

[0017] Furthermore, according to different detection requirements, different numbers of shielding box bodies are stacked on top of the shielding box body, so that multiple shielding box bodies are stacked and convenient for testing multiple different products. At the same time, different conditions inside the shielding box body can be controlled according to different requirements, so that the product test results can be more in line with the requirements;

[0018] Furthermore, the elastic layer on the inner side of the first airbag can increase the friction between the limit block and the first airbag after engagement, and the first airbag is used to fill the gap on the outer side. At the same time, the elastic layer fills the space between the limit block and the first airbag, and the anti-slip protrusion can increase the contact area between the limit block and the first airbag, so that the engagement stability of the limit block and the limit groove is improved, avoiding the problem of tipping over after stacking the shielding box bodies.

[0019] 2. The anti-skid pad is placed on the top of the shielding box body. The anti-skid pad and the wear-resistant layer can increase the friction and anti-skid performance between the two stacked shielding box bodies. The wear-resistant layer can reduce the friction of the anti-skid pad, thereby extending the service life of the anti-skid pad. The anti-skid pad and the wear-resistant layer can be clamped on the upper end of the outer side of the shielding box body through the elastic limiting piece. The elastic limiting piece can be turned over to set the card slot on the outer side of the card block, thereby fixing the position of the anti-skid pad and the wear-resistant layer. The anti-skid pad and the wear-resistant layer can be disassembled by reverse operation to avoid obstruction when the shielding box body is flipped open by the spring hook.

[0020] Furthermore, when conducting product testing, it is necessary to pull out the product placement rack, place the product to be tested on the inside of the product tooling, and then push the product placement rack into the inside of the shielding box body to reset it. During the resetting process, the guide rod can be used to assist the stable movement of the product placement rack, thereby avoiding the product placement rack being not accurate enough during resetting, resulting in inaccurate detection data. The guidance of the guide rod can also enable the product placement rack to move stably during repeated pulling and pulling, thereby avoiding the position of the product to be tested placed inside the product tooling being offset due to shaking during the movement.

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Embodiment 1:

[0030] like Figure 1-Figure 5The technical solution shown is to solve the problem of decreased overall shaking stability when the shielding box is stacked in multiple layers: the drawer shielding box for testing stackable products discloses a stacking sealing mechanism, and limiting grooves 19 are provided at the four corners at the top of the shielding box body 1, and a stacking sealing mechanism for sealing the remaining space using an air bag is provided inside the limiting groove 19, and the stacking sealing mechanism includes a limiting block 13, and the limiting block 13 is fixedly connected to the four corners at the bottom end of the shielding box body 1, and the limiting block 13 and the limiting groove 19 are engaged with each other, and a power switch 7 is provided at the middle position of one end of the other side of the shielding box body 1, and an AC socket 8 is provided on the other side of the shielding box body 1 below the power switch 7, and the other side of the shielding box body 1 is away from the power switch 7 A speed regulating valve 12 is provided on one side, a filter assembly 9 is fixedly connected to the other side of the shielding box body 1 close to the AC seat 8, and a power divider 11 is fixedly connected to the other side of the shielding box body 1 on one side of the filter assembly 9, and a radio frequency port 10 is provided on the other side of the shielding box body 1 above the filter assembly 9, a second airbag 22 is fixedly connected to the inside of the limiting groove 19, and the top of the second airbag 22 is fixedly connected to the first airbag 20 through a hose 21, the top of the first airbag 20 extends to the outside of the limiting groove 19, and an elastic layer 23 is fixedly connected to the inner side of the first airbag 20, and an anti-slip bump 24 is fixedly connected to the inner side of the elastic layer 23, the cross-section of the anti-slip bump 24 is semicircular, and the anti-slip bumps 24 are evenly spaced and distributed on the inner side of the elastic layer 23.

[0031] In this example, after the shielding box body 1 is placed, different numbers of shielding box bodies 1 are stacked on top of the shielding box body 1 according to different detection quantity requirements, so that multiple shielding box bodies 1 are stacked and convenient for detecting multiple different products. At the same time, different conditions inside the shielding box body 1 can be controlled according to different requirements, so that the detection results of the products can be more in line with the requirements. When stacking the shielding box bodies 1, the basic stacking of the shielding box bodies 1 is achieved by engaging the limit block 13 into the inside of the limit groove 19. However, since the depth and height of the limit groove 19 and the limit block 13 when engaged are relatively small, instability is likely to occur after stacking. When engaged, the limit block 13 applies a squeezing force to the second airbag 22, so that the gas inside the second airbag 22 is transported to the inside of the first airbag 20 through the hose 21, thereby expanding the first airbag 20, and using the expansion of the first airbag 20 to fill the gap generated when the limit groove 19 and the limit block 13 are engaged, thereby increasing the stability of the limit groove 19 and the limit block 13 when engaged.

[0032] Embodiment 2:

[0033] like Figure 1 , Figure 4 and Figure 6The technical solution shown is to solve the problem that the product placement rack 3 needs to be repeatedly pulled out when the product is placed in the product tooling 4, and the position of the product placement rack 3 is not accurate when it is reset, resulting in an inaccurate test structure: the drawer shielding box for stackable product testing discloses a guiding mechanism, including a shielding box body 1 and an upper cover plate 2 hinged at the top of the shielding box body 1, a guide rod 5 is slidably connected inside the shielding box body 1, one side of the guide rod 5 is fixedly connected to the product placement rack 3, and one side of the product placement rack 3 is fixedly connected to the product tooling 4, and both ends of the upper end of the other side of the shielding box body 1 are provided with spring hooks 6.

[0034] In this example, when conducting product inspection, it is necessary to pull out the product placement rack 3, place the product to be inspected on the inner side of the product tooling 4, and then push the product placement rack 3 into the inside of the shielding box body 1 to reset it. During the resetting process, the guide rod 5 can assist the stable movement of the product placement rack 3 to avoid inaccurate inspection data due to the lack of precision of the product placement rack 3 during resetting. The guidance of the guide rod 5 can also enable the product placement rack 3 to move stably during repeated pulling and pulling, to avoid the position of the product to be inspected placed inside the product tooling 4 being offset due to shaking during the movement.

[0035] Embodiment three:

[0036] like Figure 1 , Figure 2 and Figure 4 The technical solution shown is to solve the problem of instability caused by insufficient anti-slip performance between the shielding boxes when the limit groove 19 and the limit block 13 are not engaged: the drawer shielding box for testing stackable products discloses an anti-slip mechanism, which includes an anti-slip pad 14, and the anti-slip pad 14 is fixedly connected to one side between the spring hooks 6, and the top of the anti-slip pad 14 is fixedly connected to a wear-resistant layer 15, and both ends of the outside of the shielding box body 1 are fixedly connected with a clamping block 17, and a clamping groove 18 matching the clamping block 17 is opened on one side of the elastic limit plate 16.

[0037] In this example, the anti-skid pad 14 is snap-fitted and placed above the shielding box body 1. The anti-skid pad 14 and the wear-resistant layer 15 can increase the friction and anti-skid performance between the two stacked shielding box bodies 1. The wear-resistant layer 15 can reduce the friction of the anti-skid pad 14, thereby extending the service life of the anti-skid pad 14. The anti-skid pad 14 and the wear-resistant layer 15 can be snap-fitted to the upper end of the outer side of the shielding box body 1 through the elastic limiting plate 16. The elastic limiting plate 16 can be flipped over to set the slot 18 on the outer side of the block 17, thereby fixing the position of the anti-skid pad 14 and the wear-resistant layer 15. The anti-skid pad 14 and the wear-resistant layer 15 can be removed by reverse operation to avoid obstruction when the shielding box body 1 is flipped open by the spring buckle 6.

[0038] Although the 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.
