[0002] The RF functional test uses a test process that is run in parallel by multiple identical test stations. Due to the interference of multiple radio frequencies during the test process, a signal shielding box is required to ensure detection accuracy and a relatively independent detection environment.

[0003] The prior art discloses a signal shielding box for testing (CN201922303117.8), which comprises: a box body with an opening on the front side, a box door hinged on the opening of the box body, an inner wall of the box door provided with a sponge layer, a heat sink and a heat dissipation motor provided on the side panels of the box body, a power socket component and a communication interface component provided on the box body, the power socket component being provided with plug holes on the inner and outer sides of the box body, and the communication interface component being provided with communication interfaces on the inner and outer sides of the box body.

[0004] In the prior art, the box is sealed by the box door, and the box door is clamped by inserting the plug on the handle into the bearing block on the box. The degree of fit between the door and the fitting surface of the box will affect the shielding effect of the signal. As time goes by, the plug and the bearing block will wear out, so that the plug and the bearing block are no longer tightly fitted, which will cause a gap between the box and the door, and the gap cannot be automatically compensated, thereby affecting the detection result. There is a certain room for optimization in compensating the gap between the box and the door in the prior art. To this end, we propose a wireless signal shielding box. Utility Model Content

The resistance body is located in the top groove and is elastically connected to the main body. The top surface of the resistance body is provided with a deformation groove and a notch that are interconnected.

[0017] Beneficial Effects

[0018] The utility model provides a wireless signal shielding box, which has the following beneficial effects:

[0019] 1. This wireless signal shielding box is provided with a resistance body, which is elastically connected to the main body. When the cover plate and the main body are closed to form a sealed box, the resistance body can resist the bottom surface of the cover plate, thereby filling the gap between the fitting surfaces of the cover plate and the main body, thereby ensuring the sealing performance of the entire box, reducing the probability of the shielding gap caused by the gap between the cover plate and the main body affecting the detection accuracy, and ensuring the detection accuracy.

[0020] 2. This wireless signal shielding box pushes the resistance body to slide up in the top groove through the elastic member. When the cover plate and the main body are closed, the upper end surface of the resistance body can fit tightly against the bottom surface of the cover plate, thereby automatically filling the gap. The sealing can be achieved in the process of closing the cover plate without manual intervention.

[0021] 3. This kind of wireless signal shielding box, by setting a contact rod with a rubber texture, the contact rod is squeezed into the deformation groove. When the cover plate is in contact with the main body, the contact rod can buffer the bottom surface of the cover plate, thereby reducing the wear caused by the hard contact of the cover plate with the main body. At the same time, through the extrusion deformation of the contact rod, the contact rod pushes the petal structure of the resistance body, and then the petal structure of the resistance body can resist the inner bottom surface of the main body located at the top groove, thereby ensuring the fitting effect of the resistance body and the main body. The resistance body can be made of the same material as the main body, thereby allowing the resistance body and the main body to form a complete shielding cover. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] A wireless signal shielding box, such as Figure 1 and Figure 2 As shown, including:

[0031] The main body 10 is configured as a box structure with an opening at the top, and is used to load the workpiece to be inspected;

[0032] The cover plate 11 is hinged to the main body 10 and abuts against the top of the main body 10 to block the opening of the main body 10;

[0033] Specifically, the main body 10 is a box structure with an opening at the top, the cover 11 is a rectangular plate and is adapted to the opening of the main body 10, and a lock is provided between the cover 11 and the main body 10. The lock is a technology disclosed in the prior art, and its specific model and specifications are not restricted too much here. A sealed box structure is formed by the cover 11 and the main body 10 to shield the signal, thereby being able to detect the workpiece placed in the main body 10.

[0034] like Figure 3 , Figure 4 and Figure 5 As shown, the top groove 20 is provided on the top surface of the main body 10; a sealing component for sealing the gap between the main body 10 and the cover plate 11 is provided in the top groove 20, and the sealing component includes a contact body 21, a deformation groove 23, a notch 24 and a contact rod 25. The contact body 21 is located in the top groove 20 and is elastically connected to the main body 10. The top surface of the contact body 21 is provided with a deformation groove 23 and a notch 24 that are interconnected. The top surface of the contact body 21 forms a petal-like structure through the deformation groove 23 and the notch 24 and contacts the inner wall of the main body 10. The contact rod 25 is detachably installed in the deformation groove 23, and the cover plate 11 can squeeze the contact rod 25 to deform so that The petal structure of the resistance body 21 is expanded, and the top groove 20 forms a U-shaped groove. The resistance body 21 cooperates with the top groove 20, and the resistance body 21 is slidably connected to the top groove 20. In this solution, by setting the resistance body 21, the resistance body 21 is elastically connected to the main body 10. When the cover plate 11 and the main body 10 are closed to form a sealed box, the resistance body 21 can resist the bottom surface of the cover plate 11, thereby filling the gap between the fitting surface of the cover plate 11 and the main body 10, thereby ensuring the sealing performance of the entire box, reducing the probability of the shielding gap caused by the gap formed between the cover plate 11 and the main body 10 affecting the detection accuracy, and ensuring the detection accuracy.

[0035] like Figure 6 and Figure 7 As shown, the sealing assembly also includes an elastic member 22. A plurality of elastic members 22 are arranged on the bottom surface of the abutment 21. The abutment 21 is elastically connected to the main body 10 through the elastic members 22. The elastic members 22 are fixedly installed at the four corners of the bottom surface of the abutment 21. The elastic members 22 include springs but are not limited to springs. By arranging the elastic members 22, the other end of the elastic members 22 is fixedly connected to the inner bottom surface of the main body 10. The abutment 21 is pushed to slide up in the top groove 20 by the elastic members 22. When the cover plate 11 and the main body 10 are closed, the upper end surface of the abutment 21 can fit tightly against the bottom surface of the cover plate 11, thereby achieving the purpose of automatically making up the gap. Sealing can be achieved in the process of covering the cover plate 11 without manual intervention.

[0036] like Figure 7As shown, the deformation groove 23 surrounds the top surface of the contact body 21 and forms a closed U-shaped groove. The opposite side walls of the contact body 21 are provided with the same notch 24, which extends from the outer wall of the contact body 21 to the deformation groove 23. Two notches 24 are provided on the same side wall of the contact body 21. The contact rod 25 forms a U-shaped frame structure. The contact rod 25 and the deformation groove 23 are interference fit. The thickness of the contact rod 25 is greater than the depth of the deformation groove 23. The interior of the contact rod 25 is hollow and forms an air storage cavity. By setting the contact rod 25 with a rubber texture, the contact rod 25 is squeezed When the cover 11 enters the deformation groove 23 and fits with the main body 10, the contact rod 25 can cushion the bottom surface of the cover 11, thereby reducing the wear caused by the hard contact of the cover 11 with the main body 10. At the same time, through the extrusion deformation of the contact rod 25, the contact rod 25 pushes the petal-shaped structure of the contact body 21, and then the petal-shaped structure of the contact body 21 can contact the inner bottom surface of the main body 10 located at the top groove 20, thereby ensuring the fitting effect of the contact body 21 and the main body 10. The contact body 21 can be made of the same material as the main body 10, so that the contact body 21 and the main body 10 form a complete shielding cover.

[0037] The working principle of the utility model is as follows: the contact rod 25 is squeezed into the deformation groove 23. When the cover plate 11 is fitted with the main body 10, the contact rod 25 can buffer the bottom surface of the cover plate 11, reduce the wear caused by the hard contact of the cover plate 11 with the main body 10, and push the resistance body 21 to slide up in the top groove 20 through the elastic member 22. When the cover plate 11 and the main body 10 are closed, the upper end surface of the resistance body 21 can be tightly fitted with the bottom surface of the cover plate 11, so as to achieve the purpose of automatically filling the gap. The contact rod 25 is squeezed and deformed by the cover plate 11 to squeeze the petal structure of the resistance body 21, and then the petal structure of the resistance body 21 can contact the inner bottom surface of the main body 10 located at the top groove 20, so as to ensure the fitting effect of the resistance body 21 and the main body 10, fill the gap between the fitting surfaces of the cover plate 11 and the main body 10, and then ensure the sealing performance of the entire box body and the detection accuracy.
