[0025] As Figures 1 to 4 shown, the draw - type test box of the present utility model includes: a box body 1, the box body 1 is provided with at least one set of support structures along the height direction, and the support structure at least includes an upper guide rail 21 and a lower guide rail 22; a carrier plate 3, the top surface of the carrier plate 3 is provided with an upper slider 41 that cooperates with the upper guide rail 21, and the bottom surface of the carrier plate 3 is provided with a lower slider 42 that cooperates with the lower guide rail 22; a reinforcing structure 5, the reinforcing structure 5 is arranged between the box body 1 and the carrier plate 3, and is used to improve the bearing strength when the carrier plate 3 is pulled out.

[0026] See Figure 1 , multiple sets of support structures are arranged in the box body 1 along the height direction. Each set of support structures at least includes two upper guide rails 21 and two lower guide rails 22 arranged on both sides inside the box body 1. The top surface of the carrier plate 3 is connected to the upper guide rail 21 through the upper slider 41, and the bottom surface of the carrier plate 3 is connected to the lower guide rail 22 through the lower slider 42. The bottom surface of the carrier plate 3 and the reinforcing structure 5 arranged inside the box body 1 can further support the carrier plate 3, ensuring that the carrier plate 3 still has a certain bearing capacity after being pulled out of the box body 1.

[0027] In this application, the carrier plate 3 is limited and supported by the upper guide rail 21 and the lower guide rail 22, and the reinforcing structure 5 is used for reinforcing support to increase the bearing weight of the carrier plate 3 of this application and expand the applicable range of this application; at the same time, by configuring the carrier plate 3 as a draw - type, the applicable range of this application can be further expanded, which has practicality.

[0028] In one or more embodiments, the reinforcing structure 5 at least includes support rollers 51 arranged on the box body 1, wherein the support rollers 51 are in contact with the lower surface of the carrier plate 3; the support rollers 51 are relatively located at one end of the box body 1 close to the drawing - out direction of the carrier plate 3.

[0029] See Figures 1 to 4, the supporting roller 51 is relatively located at the bottom of the bearing plate 3, and the supporting roller 51 is relatively located near the opening of the box body 1, that is, in the direction where the bearing plate 3 is drawn out of the box body 1. Through this setting, when the bearing plate 3 is gradually drawn out of the box body 1, the supporting roller 51 located at the opening of the box body 1 can support the bottom of the bearing plate 3, so as to reduce the problem that the connection between the bearing plate 3 and the lower sliding block 42 is deformed due to the bearing plate 3 carrying a large amount of heavy objects. At the same time, the top surface of the bearing plate 3 is connected to the upper guide rail 21 through the upper sliding block 41, and the bottom surface is connected to the lower guide rail 22 through the lower sliding block 42, so as to further limit the position of the bearing plate 3, ensure the bearing strength of the bearing plate 3, and improve the application range and service life of the present application.

[0030] In other possible embodiments, the supporting roller 51 can also be arranged on one side of the box body 1 away from the drawing direction of the bearing plate 3 to further improve the supporting effect of the supporting roller 51 on the bearing plate 3.

[0031] In one or more embodiments, a stop block 6 is arranged at one end of the upper guide rail 21 and / or the lower guide rail 22 close to the drawing direction of the bearing plate 3.

[0032] See Figure 1 , Figure 3 , Figure 4 , a stop block 6 is arranged at one end of the upper guide rail 21 close to the opening of the box body 1, and a stop block 6 is arranged at one end of the lower guide rail 22 close to the opening of the box body 1; it should be noted that the stop block 6 arranged at the end of the upper guide rail 21 can limit the position of the upper sliding block 41, and the stop block 6 arranged at the end of the lower guide rail 22 can limit the position of the lower sliding block 42, so as to avoid the problem that the bearing plate 3 slides out of the guide rail and causes the carried objects to fall, and improve the safety and stability of the use of the present application.

[0033] In other possible embodiments, a rubber pad is installed on the surface of the stop block 6 facing the bearing plate 3. When the upper sliding block 41 or the lower sliding block 42 impacts the stop block 6, the rubber pad can provide buffering for the upper sliding block 41 or the lower sliding block 42 to contact the stop block 6, reduce the damage of the stop block 6, and reduce the generation of noise.

[0034] In one or more embodiments, the upper sliding block 41 and the lower sliding block 42 are located at one end of the bearing plate 3 relatively far from the drawing direction of the bearing plate 3. See Figure 4 , through this setting, the distance that the bearing plate 3 is drawn out of the box body 1 can be further increased, the range of objects carried by the bearing plate 3 can be increased, the use effect of the present application can be improved, and it has practicability.

[0035] In one or more embodiments, a support plate 7 is arranged at the bottom of the bearing plate 3, and the bearing plate 3 is installed on the lower sliding block 42 through the support plate 7, and the supporting roller 51 is always in contact with the support plate 7.

[0036] See Figure 3 , the support plate 7 is a sheet metal part. In the initial state, the bearing plate 3 is located inside the box body 1. At this time, the support plate 7 abuts against the support roller 51 at the opening of the box body 1, and the lower slider 42 is located inside the box body 1. Through this setting, the stability of the bearing plate 3 for bearing objects can be ensured, and the use effect of this application can be improved; when the bearing plate 3 is pulled out of the box body 1, the bearing plate 3 always slides on the support roller 51 through the support plate 7.

[0037] In one or more embodiments, a handle 8 is configured on the bearing plate 3. See Figure 1 , the handle 8 is configured on one side surface of the bearing plate 3 in the direction of being pulled out of the box body 1.

[0038] In one or more embodiments, at least two groups of lower sliders 42 are configured at the bottom of the bearing plate 3. Through this setting, the bearing strength of the bearing plate 3 for objects can be further improved, and the applicable range of this application can be increased.

[0039] In other possible embodiments, along the direction in which the bearing plate 3 is pulled out, a copper tube is configured at the opening of the box body 1, and a rubidium magnet capable of extending into the copper tube is configured on the side of the lower slider 42.

[0040] It should be noted that the rubidium magnet and the copper tube are coaxial, and the outer diameter of the rubidium magnet is less than or equal to the inner diameter of the copper tube, so that the rubidium magnet can extend into the copper tube. When the bearing plate 3 is about to be completely pulled out of the box body 1, the rubidium magnet extending from the side of the lower slider 42 will enter the copper tube. The rubidium magnet moves in the copper tube and cuts the magnetic induction line to generate a Lorentz force to hinder the movement of the rubidium magnet, and then hinder the movement of the lower slider 42 on the lower guide rail 22, so that a damping effect is generated before the bearing plate 3 is about to be completely pulled out, so as to achieve the effect of reminding the staff to slow down the pulling speed of the bearing plate 3, and at the same time, the problem that the objects on the bearing plate 3 are displaced due to too fast pulling speed can be reduced, which has practicability.

[0041] The above embodiments are only for illustrating the technical concept and characteristics of the present invention, and the purpose is to enable those who are familiar with this technology to understand the content of the present invention and implement it, and cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
