Description

Technical Field

[0001] This utility model relates to the field of accessory box protection, specifically an anti-drop mechanism for an accessory box of a current transformer tester. Background Technology

[0002] The instrument transformer tester accessory box is mainly used to organize and store the accessories of the instrument transformer tester, so that all accessories can be stored and organized in a unified manner, making the accessories of the instrument transformer tester easier to carry, and providing a certain degree of protection for the internal accessories.

[0003] Existing instrument accessory boxes for current transformer testers primarily rely on the box body to protect the internal accessories during use. However, when the box body is dropped, the vibration will directly affect the internal accessories, potentially causing damage. Furthermore, there is no external protective structure on the box body when it falls, which can also damage the accessory box itself, significantly reducing its protective effect on the internal accessories. Therefore, it is necessary to design a drop-proof mechanism for instrument transformer tester accessory boxes to solve these problems. Utility Model Content

[0004] The purpose of this utility model is to provide a drop-proof mechanism for the accessory box of a current transformer tester, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a drop-proof mechanism for an accessory box of a current transformer tester, comprising a box body and a handle, wherein a metal plug is slidably connected to the inner side wall of the box body, a support tube is fixedly connected to the upper end of the metal plug body, a pressure-bearing slide rod is slidably connected to the inner side of the support tube body, and an elastic air cushion is fixedly connected to the upper end of the pressure-bearing slide rod.

[0006] The side of the box is fixedly connected to a mounting shell, and an outer protective pad is slidably connected to the outer side of the mounting shell. End face pads are fixedly connected to the upper and lower end faces of the box.

[0007] Preferably, the front left and right sides of the box are provided with latches, and a handle is rotatably connected at the middle position of the front of the lower side of the box.

[0008] Preferably, the upper and lower end faces of the box are provided with circular grooves, and magnetic blocks are provided inside the circular grooves. The magnetic blocks are fixedly connected to the box, and the circular grooves are arranged in a rectangular array.

[0009] Preferably, the support tube is provided with a spring inside.

[0010] Preferably, the elastic air cushion has a deformation buffer cavity inside.

[0011] Preferably, an opening end protective block is fixedly connected to each of the front corners of the box body, and the opening end protective block is made of rubber.

[0012] Preferably, the fixed mounting shell has an internal buffer pad inside, and a pressure transmitting plate is provided on the outside of the internal buffer pad. The pressure transmitting plate is slidably connected to the fixed mounting shell, and the pressure transmitting plate is fixedly connected to the outer protective pad.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The anti-drop mechanism of the instrument transformer tester accessory box allows the elastic air cushion to adhere to the surface of the accessory by closing the box, thus providing elastic clamping for the accessory. When the box is dropped, the elastic air cushion provides primary protection for the accessory, preventing the vibration force from directly acting on it. Furthermore, the metal insert can be inserted into a circular slot at any position and magnetically connected to the internal magnetic block. Different accessories will compress the elastic air cushion to varying degrees, causing the pressure-bearing slide rod and spring to be compressed to different degrees. This allows the device to provide effective protection based on the location and shape of the accessory.

[0015] 2. The anti-drop mechanism of the instrument transformer tester accessory box, through the protective block at the open end, can protect the open end from falling and prevent damage to the lock and handle. When the side hits the ground, the outer protective pad can protect the side of the box and transfer the impact force to the pressure plate, thereby allowing the internal buffer pad to buffer the impact force. When the front and back of the box hit the ground, the end face pads can protect the front and back of the box, so that the box can be effectively protected and the service life of the accessory box can be guaranteed.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] Please refer to Figure 1-5 As shown, this utility model provides a drop protection mechanism for an accessory box of a current transformer tester, including a box body 1 and a handle 10. A metal plug 2 is slidably connected to the inner side wall of the box body 1. A support tube 3 is fixedly connected to the upper end of the metal plug 2. A pressure-bearing slide rod 4 is slidably connected to the inner side of the support tube 3. An elastic air cushion 5 is fixedly connected to the upper end of the pressure-bearing slide rod 4. The elastic air cushion 5 can play a major protective role for the accessory and prevent the vibration force from acting directly on the accessory.

[0025] A fixed mounting shell 6 is fixedly connected to the side of the box 1. An outer protective pad 7 is slidably connected to the outer side of the fixed mounting shell 6. The outer protective pad 7 can provide pre-support for the side of the box 1. End face pads 8 are fixedly connected to the upper and lower end faces of the box 1. The end face pads 8 can provide buffer protection for the upper and lower end faces of the box 1 to prevent damage to the upper and lower end faces of the box 1.

[0026] Specifically, the front left and right sides of the box 1 are equipped with latches 9, and the lower side of the box 1 is rotatably connected to the middle of the front of the box 1.

[0027] Specifically, the upper and lower end faces of the box 1 are provided with circular grooves 11, and magnetic blocks 12 are provided inside the circular grooves 11. The magnetic blocks 12 are fixedly connected to the box 1. The circular grooves 11 are arranged in a rectangular array. The arrangement of a large number of circular grooves 11 and magnetic blocks 12 allows the metal plugs 2 to be installed arbitrarily according to the placement position of the accessories, so as to protect different types of accessories.

[0028] Specifically, the support tube 3 is equipped with a spring 13 inside. Different accessories cause the spring 13 to be compressed to different degrees, thereby enabling the device to perform effective protection treatment at the corresponding position according to the location and shape of the accessory.

[0029] Specifically, the elastic air cushion 5 has a deformation buffer cavity 14 inside.

[0030] Specifically, each of the front corners of the housing 1 is fixedly connected with an opening end protection block 15. The opening end protection block 15 is made of rubber. The opening end protection block 15 can protect the opening end and prevent the lock 9 and handle 10 from falling and breaking.

[0031] Specifically, the fixed mounting shell 6 has an internal buffer pad 16 inside, and a pressure transmission plate 17 is provided on the outside of the internal buffer pad 16. The pressure transmission plate 17 is slidably connected to the fixed mounting shell 6, and the pressure transmission plate 17 is fixedly connected to the outer protective pad 7. The outer protective pad 7 can pre-support the side of the box 1 and can transmit the impact force to the pressure transmission plate 17 so that the internal buffer pad 16 can buffer the impact force, greatly reducing the risk of damage after the side lands.

[0032] Working Principle: This utility model is a drop protection mechanism for an instrument transformer tester accessory box. When the instrument transformer tester accessory box falls, the protective block 15 at the open end protects the open end, preventing the latch 9 and handle 10 from falling and breaking. The end face pad 8 cushions the upper and lower end faces of the box body 1, preventing them from breaking. When the side first hits the ground, the outer protective pad 7 pre-supports the side of the box body 1 and transmits the impact force to the pressure plate 17, allowing the internal buffer pad 16 to buffer the impact force. This design significantly reduces the risk of damage after a side impact. When the housing 1 falls, the elastic air cushion 5 provides primary protection for the accessories, preventing the impact force from directly affecting them. The metal insert 2 can be inserted into the circular slot 11 at any position and magnetically connected to the internal magnetic block 12. Different accessories will compress the elastic air cushion 5 to varying degrees, causing the pressure-bearing slide rod 4 and the spring 13 to be compressed to different degrees. This allows the device to provide effective protection based on the location and shape of the accessories.
