DETAILED DESCRIPTION OF THE INVENTION

[0017] The present invention is not limited by the following embodiments, and the specific implementation manners can be determined according to the technical solutions of the present invention and the actual situation.

[0018] In the present invention, for the convenience of description, the description of the relative positional relationship of each component is based on the layout mode of the attached drawings of the specification. Figure 1 For example, the positional relationships such as front, rear, upper, lower, left, and right are determined according to the layout direction of the attached drawings of the specification.

[0019] The present invention will be further described below in conjunction with embodiments and drawings: Embodiment 1: As attached Figures 1-5 As shown, the box body for convenient placement of high-voltage switch cabinet relay protection test tools includes a portable box 1, a sealing cover 2, a storage box 5, a support block 6, a support plate 8, and a lifting assembly. The sealing cover 2 is hinged on the portable box 1, and the storage box 5 is installed in the portable box 1. An isolation groove is provided between the portable box 1 and the storage box 5. A shielding cover 12 is hinged on the storage box 5, and a support block 6 is provided in the storage box 5. The storage box 5 is provided with a lifting assembly that can be linked with the shielding cover 12 to push the support block 6 upward, and a support plate 8 is provided on the upper side of the support block 6.

[0020] When in use, rotate to open the sealing cover 2, and then rotate to open the shielding cover 12. While the shielding cover 12 rotates, it cooperates with the lifting assembly to push the support block 6 upward, thereby pushing the tester 11 placed on the support plate 8 upward. The position of the tester 11 after moving up does not affect the wiring and use. Therefore, the tester 11 can be directly operated and used after moving up without being taken out. After use, close the shielding cover 12. While the shielding cover 12 rotates, it cooperates with the lifting assembly to push the support block 6 downward, thereby completing the storage of the tester 11. It is convenient and fast, and there is no need to frequently take it in and out. An isolation groove is provided between the portable box 1 and the storage box 5 to isolate the external temperature to a certain extent, thereby preventing the external temperature from causing overheating of the tester 11.

[0021] According to actual needs, the above-mentioned box for facilitating the placement and access of the high-voltage switchgear relay protection test tool can be further optimized or / and improved: Embodiment 2: As attached Figures 2-5 As shown, the lifting assembly includes two groups of linkage mechanisms, which are respectively arranged on the left and right sides of the storage box 5 and are symmetrically distributed. The linkage mechanism includes a flat belt 13, an eccentric wheel 14, and a connecting frame 15. A pulley is fixedly installed on the end of the hinge shaft of the shielding cover 12, and an eccentric wheel 14 is rotatably installed on the side of the storage box 5. A pulley is fixedly installed on the rotating shaft inside the eccentric wheel 14. The two pulleys are connected by a flat belt 13. The front part of the eccentric wheel 14 is rotatably connected to the connecting frame 15. A roller 16 is rotatably installed between the connecting frames 15 of the two groups of linkage mechanisms. The lower side of the front end of the support block 6 has an inclined surface with a high front and a low back, and the roller 16 can move along the inclined surface.

[0022] When the shielding cover 12 is opened, the rotation of the rotating shaft drives the pulley to rotate, causing the flat belt 13 to rotate, driving the eccentric wheel 14 to rotate backward. By the rotation of the eccentric wheel 14, the connecting frame 15 is pulled to rotate, causing the roller 16 to move backward and rotate. By the movement of the roller 16 along the inclined surface and squeezing the support block 6 to move upward, the tester 11 on the support plate 8 is lifted upward. Thus, the tester 11 can be automatically lifted while the shielding cover 12 is opened. When the shielding cover 12 is closed, the rotating shaft rotates in the reverse direction, and the eccentric wheel 14 pulls the connecting frame 15 to make the roller 16 move forward along the inclined surface, causing the support block 6 to slowly fall, with convenient operation.

[0023] Embodiment 3: As shown in the appendix Figure 4 As shown, a number of shock absorbers 7 are connected between the support plate 8 and the support block 6. When the portable case 1 accidentally falls during transportation, shock absorption treatment is carried out through the shock absorbers 7.

[0024] Embodiment 4: As shown in the appendix Figure 4 As shown, sliders are respectively installed on the left and right sides of the support block 6, and sliding grooves matching the sliders are provided on the left and right sides of the storage box 5. By setting the sliders and sliding grooves, the movement path of the support block is restricted, so that it is more stable and not easy to shake when moving up and down.

[0025] Embodiment 5: As shown in the appendix Figure 3 As shown, fans 10 are installed on the left and right sides of the portable case 1, and dust-proof nets 9 are installed on the outer sides of the fans 10. When the storage area of the portable case 1 is overheated, the fans 10 can be started. Through the heat dissipation of the fans 10 and the filtering of dust through the dust-proof nets 9, heat dissipation treatment can be carried out on the tester 11 when the environmental temperature is overheated, avoiding the influence on use due to too high temperature.

[0026] Embodiment 6: As shown in the appendix Figure 3 As shown, a drawer 4 is slidably connected to the lower part of the portable case 1, a handle is provided on the front side of the drawer 4, and a handle 3 is hinged to the front part of the portable case 1. The portable case 1 can be conveniently lifted directly through the handle 3, and tools can be placed through the drawer 4.

[0027] The above technical features respectively constitute the embodiments of the present invention, which have strong adaptability and implementation effects. Non-essential technical features can be added or reduced according to actual needs to meet the requirements of different situations.
