[0028] Embodiment 1

[0029] See also Figure 1-Figure 6 A three-integrated test box includes a test box body 1, a test chamber 2 is arranged in the test box body 1, a door panel 3 completely covering the test chamber 2 is arranged on one side of the test box body 1, a support plate 4 is arranged in the test chamber 2, a symmetrical side plate 5 is fixedly installed on the upper surface of the support plate 4, a plurality of placement plates 6 are arranged between the two side plates 5, a vibration unit for vibration is arranged on the lower surface of the support plate 4, two symmetrical and U-shaped clamping frames 7 are arranged on the opposite sides of the placement plates 6, a moving chamber 8 is opened in the side plates 5, two moving grooves 9 adapted to the clamping frames 7 and connected to the moving chamber 8 are opened on the opposite surfaces of the two side plates 5, and a plurality of teeth are opened on the opposite side walls of the two moving grooves 9 Slot 10, a plurality of limit plates 11 adapted to the movable slot 9 are arranged in the movable cavity 8, one side of the limit plate 11 is adapted to the tooth groove 10 and the limit plate 11 is adapted to the clamping frame 7, a plurality of bidirectional screw rods 12 extending into the movable cavity 8 are passed through one side of the side plate 5, each bidirectional screw rod 12 passes through two limit plates 11 and is threadedly connected with the two limit plates 11, and the bidirectional screw rod 12 drives the two limit plates 11 to move toward or away from each other when rotating, and an adjusting slot 21 connected to the movable cavity 8 is provided on the side of the side plate 5 close to the door panel 3, one end of the bidirectional screw rod 12 passes through the adjusting slot 21 and extends to the outside, and one end of the bidirectional screw rod 12 extending to the outside is fixedly connected to a rotating plate 22.

[0030] The specific implementation method in this embodiment is as follows: Figure 1As shown, the structure of the test box body 1 in this embodiment is similar to the structure of the existing three-integrated test box, such as a conveniently layered three-integrated test box disclosed in the patent with publication number CN213263457U. The main improvement of this embodiment is that it is more convenient to adjust the placement plate 6 and expand the adjustment range of the placement plate 6; in this embodiment, when the product needs to be subjected to the three-integrated test, the spacing between the placement plates 6 is adjusted according to the height of the product. During adjustment, the two-way screw rod 12 is rotated by rotating the rotating plate 22. When the two-way screw rod 12 rotates, it drives the two limit plates 11 to move toward each other. At the same time, the limit plates 11 are all moved in the clamping frame 7. The clamping frame 7 is supported by the limit plates 11. The two limit plates 11 are separated from the tooth grooves 10 on the side walls of the moving groove 9, and the position of the placement plate 6 can be adjusted. During adjustment, the two-way screw rod 12 moves in the adjustment groove 21, and the clamping frame 7 and the limit plates 11 move in the moving cavity 8 and the moving groove 9. After the positions of several placement plates 6 are adjusted, By rotating the two-way screw rod 12 in the opposite direction, the two-way screw rod 12 drives the two limit plates 11 to move away from each other, and the limit plates 11 are meshed with the tooth grooves 10 on the moving grooves 9, thereby limiting the position of the placement plate 6. If necessary, a nut can be installed on the side of the two-way screw rod 12 to fix the position of the two-way screw rod 12. Normally, the position of the two-way screw rod 12 can be fixed by tightening the rotating plate 22 to fix the product on the placement plate 6. The method of fixing the product on the placement plate 6 is an existing known technology and will not be introduced in detail here. By starting the vibration unit on the lower surface of the support plate 4, a vibration test is performed on the product, and the temperature and humidity test is performed on the product through the internal equipment of the test box body 1. Through the above-mentioned setting, it is convenient for the test personnel to adjust the position of the placement plate 6, and the adjustment range of the placement plate 6 is expanded. Two adjacent placement plates 6 can be adjusted to be infinitely close, and the overall structure is simple, which reduces the manufacturing cost of the overall device.

[0031] Embodiment 2

[0032] See also Figure 2 and Figure 3 This embodiment includes the above-mentioned embodiment, wherein the vibration unit includes a vibration motor 13 fixedly mounted on the lower surface of the supporting plate 4, a plurality of first bearing columns 14 are fixedly connected to the bottom of the test chamber 2, a plurality of second bearing columns 15 are fixedly connected to the lower surface of the supporting plate 4, and the lower ends of the second bearing columns 15 are inserted into the upper ends of the first bearing columns 14. An elastic member 16 is provided between the lower surface of the supporting plate 4 and the bottom of the test chamber 2 and is sleeved on the sides of the first bearing columns 14 and the second bearing columns 15. The elastic member 16 is a spring.

[0033] Specific implementation method in this embodiment: when it is necessary to perform a vibration test on the product, since the side panel 5 has no connection with the inner wall of the test chamber 2, when the vibration motor 13 is started, the vibration motor 13 will generate a vibration force on the support plate 4, and since the first bearing column 14 and the second bearing column 15 limit the support plate 4, the support plate 4 vibrates up and down, and cooperates with the elastic member 16 to perform a vibration test on the product fixedly installed on the placement plate 6, thereby improving the overall test effect.

[0034] Among them, the vibration motor 13 mentioned above can be purchased on the market. It is a mature technology and has been fully disclosed, so it is not repeated in the specification. The vibration motor 13 is equipped with a power connection line, and it is electrically connected to the external main controller and 220V phase voltage (or 380V line voltage) through the power line, and the main controller can be a conventional known device such as a computer that plays a control role.

[0035] Implementation Three

[0036] See also Figure 4 and Figure 5 This embodiment includes all the above embodiments, which further includes: sliding grooves 17 adapted to the clamping frame 7 are provided on the opposite sides of the placement plate 6, a waist-shaped groove 18 penetrating the placement plate 6 is provided on the lower side wall of the sliding groove 17, and a fixing bolt 19 with one end threadedly connected to the lower side of the clamping frame 7 is passed through the waist-shaped groove 18; a plurality of grooves 20 are provided on the lower surface of the placement plate 6, and the grooves 20 are adapted to the waist-shaped groove 18 and the fixing bolts 19; and a plurality of universal wheels 23 are fixedly installed on the lower end of the test box body 1.

[0037] Specific implementation method of this embodiment: Through the above-mentioned setting, the effect of adding or reducing the placement plates 6 can be achieved. When the height of the product to be tested is too high, too many placement plates 6 will block the installation of the product. At this time, it is necessary to remove several placement plates 6, loosen the fixing bolts 19, move the clamping frame 7 into the sliding groove 17, and the clamping frame 7 is disengaged from the limiting plate 11, and the placement plates 6 can be removed. The same reverse operation can be used to increase the number of placement plates 6, thereby increasing the application range of the overall device. The screw head position of the fixing bolt 19 is located in the groove 20, which will not affect the spacing between adjacent placement plates 6. The overall device can be displaced through the universal wheel 23, which is convenient for moving the overall device.

[0038] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
