[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention

[0025] Embodiment 1:

[0026] As Figures 1-4 shown, the present invention provides a technical solution: a device for installing a circuit breaker, including: a protection mechanism 1, a clamping mechanism 2 is arranged inside the protection mechanism 1, and an installation mechanism 3 is arranged on one side of the clamping mechanism 2

[0027] The clamping mechanism 2 includes a limit clamping post 21. Rubber clamping rings 22 are arranged on the outer sides of the top and bottom of the limit clamping post 21. A clamping plate 23 is arranged on the outer side of the rubber clamping ring 22. A threaded connecting plate 24 is arranged on one side of the limit clamping post 21. A threaded rod 25 is arranged inside the threaded connecting plate 24. The outer side of the rubber clamping ring 22 is fixedly connected to the inside of one side of the clamping plate 23. The inner side of the rubber clamping ring 22 is slidably clamped with the outer side of the limit clamping post 21. Thus, through the sliding limit balls arranged on the limit clamping post 21, it is better to facilitate the sliding clamping effect between the limit clamping post 21 and the rubber clamping ring 22. One end of the threaded rod 25 away from the threaded connecting plate 24 is fixedly connected to one side of the threaded sleeve 31 through a connecting block, thereby increasing the connection effect between the clamping mechanism 2 and the installation mechanism 3. The top and bottom of the limit clamping post 21 are respectively fixedly connected to both ends of the threaded connecting plate 24, thereby increasing the connection effect between the limit clamping post 21 and the threaded connecting plate 24. The inside of the threaded connecting plate 24 is threadedly connected to the outer side of the threaded rod 25. Thus, when the threaded rod 25 is rotated, the threaded connecting plate 24 can be adjusted in the front and back trajectory, thereby better facilitating the adjustment and use of the clamping plate 23, better facilitating the movement of the wire terminal clamped inside the clamping plate 23 into the connection port of the circuit breaker, and further better facilitating the installation by the user

[0028] Embodiment 2:

[0029] As Figures 1-4As shown in the figure, the protection mechanism 1 includes a fixed protection shell 11. At the top of the fixed protection shell 11, there is a protection top cover 12. Fixed clamping columns 13 are equidistantly arranged between the two sides of the fixed protection shell 11 and the protection top cover 12. The protection top cover 12 is clamped to the fixed protection shell 11 through the fixed clamping columns 13. Thus, through the installed fixed clamping columns 13, it is more convenient for users to disassemble and use the fixed protection shell 11, and further more convenient for users to install, disassemble and overhaul. It should be noted that installation holes are provided at the four corners of the bottom end of the protection top cover 12, which is more convenient for users to install the device. Inside the fixed protection shell 11, there is a circuit breaker body 101, which is more convenient for users to conduct circuit protection. Fixed slots are drilled on both sides of the circuit breaker body 101. The outer side of the conical threaded hollow fixing part 34 is fixedly clamped to the inner side of the fixed slot. Thus, through the fixed slots drilled on the circuit breaker, it is more convenient for the installation mechanism 3 to be installed and used;

[0030] The installation mechanism 3 includes a threaded sleeve 31. Inside the threaded sleeve 31, there is a locking screw rod 32. The inner end of the threaded sleeve 31 is threadedly connected to the outer side of the locking screw rod 32. At one end inside the threaded sleeve 31, there is a connecting column 33. The threaded sleeve 31 is fixedly connected to the outer side of one end of the conical threaded hollow fixing part 34 through the connecting column 33. Through the installed connecting column 33, it is more convenient for the connection effect between the threaded sleeve 31 and the conical threaded hollow fixing part 34, and further limits the conical threaded hollow fixing part 34. Through the installed threaded sleeve 31, it is also more convenient for the connection between the installation mechanism 3 and the protection mechanism 1. On the outer side of one end of the locking screw rod 32, there is a conical threaded hollow fixing part 34. The outer side of one end of the locking screw rod 32 is threadedly connected to the inside of the conical threaded hollow fixing part 34. Since the conical threaded hollow fixing part 34 adopts a conical hollow threaded design, the threaded connection between the conical threaded hollow fixing part 34 and the locking screw rod 32 can form extrusion on the inside of the conical threaded hollow fixing part 34 by rotating the locking screw rod 32. Thus, the conical threaded hollow fixing part 34 can be expanded outward, achieving the effect of fixing the inside of the fixed slot through the conical threaded hollow fixing part 34, and increasing the fixing effect between the circuit breaker and the installation mechanism 3.

[0031] Working principle:

[0032] As Figures 1-4As shown, the installed fixed clamping posts 13 can better facilitate the clamping effect between the protective shell 11 and the protective top cover 12, thus better facilitating the installation, disassembly and maintenance of the protective mechanism 1 by the user. Through the sliding clamping balls installed on the limit clamping posts 21, it is better to facilitate the sliding clamping effect between the limit clamping posts 21 and the rubber clamping rings 22. Thus, through the sliding clamping between the limit clamping posts 21 and the rubber clamping rings 22, it is better to facilitate the fixing effect of the clamping plate 23 on the wire terminals clamped inside. Through the installed threaded connecting plate 24, it can better connect the limit clamping posts 21 and the threaded rod 25. Due to the threaded connection between the threaded connecting plate 24 and the threaded rod 25, when the threaded rod 25 rotates, the threaded connecting plate 24 can be moved back and forth, and then the wire terminals clamped by the clamping plate 23 are moved inside the wire interface of the circuit breaker body 101. Through the installed threaded sleeve 31, it can better connect the threaded rod 25 and the fixed protective shell 11, and increase the connection effect between the installation mechanism 3 and the fixed protective shell 11, and limit the conical threaded hollow fixing part 34 and the locking screw rod 32. Due to the threaded connection between the locking screw rod 32 and the threaded sleeve 31, the inside of the conical threaded hollow fixing part 34 can be squeezed by rotating the locking screw rod 32. Due to the threaded connection between the locking screw rod 32 and the conical threaded hollow fixing part 34, the conical threaded hollow fixing part 34 can be expanded outward, increasing the fixing effect between the conical threaded hollow fixing part 34 and the fixed groove. Through the installed clamping mechanism 2, it is better to facilitate the user to free both hands to fix the wire terminals during wire installation, and then better facilitate the operation of using a screwdriver to fix the fixing screws on the circuit breaker body 101, and can avoid the finger soreness caused by manual clamping and fixing in the past. Through the installed installation mechanism 3 and protective mechanism 1, it is better to facilitate the installation of the device and the protection of the circuit breaker body 101, thus better facilitating the use of the user.

[0033] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as the technical content of the present invention is not departed from, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
