It is an extremely important power control facility, usually installed in a distribution cabinet or distribution box.

[0003] After searching and researching, it is found that the current installation of circuit breakers usually adopts a bolt installation method, and the circuit breaker is installed in the box through multiple long bolts. However, this disassembly and assembly structure still has some shortcomings during use: its installation and disassembly speed is slow, which affects the installation efficiency. When a fault occurs and needs to be disassembled and replaced, there is an inconvenient operation problem. Therefore, it is urgent to improve the existing circuit breaker disassembly and assembly structure and provide a circuit breaker disassembly and assembly structure that is easy to operate.

[0008] As a preferred embodiment, the positioning assembly includes a threaded rod, a positioning disc and a block. The front end of the threaded rod is fixedly connected to the positioning disc, and the rear end of the threaded rod is sleeved with a block on the outer side of the bearing, and the block slides on the inner side of the slide groove.

[0009] As a preferred implementation, the threaded rod is connected to the mounting plate by threaded connection, and a protrusion is provided on the outer wall of the middle part of the front end of the positioning disc.

[0010] As a preferred embodiment, the limiting groove includes a vertical through groove and a circular groove, the vertical through groove is opened in the middle of the bottom end of the connecting plate, and the circular groove is opened on the top of the vertical through groove.

[0011] As a preferred embodiment, the thickness of the vertical through groove is equal to the thickness of the connecting plate, the thickness of the circular groove is only one half of the thickness of the vertical through groove, the width of the vertical through groove is equal to the diameter of the threaded rod, and the diameter of the circular groove is equal to the diameter of the positioning disk.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] In the solution of the utility model:

[0015] During installation, first insert the fixing block of the outer wall of the rear end of the connecting plate into the positioning groove, and then control the connecting plate to move downward. At this time, since the intersection surfaces of the fixing block and the positioning groove are both inclined, the fixing block can drive the connecting plate to move backward during the downward movement, which is convenient for the connecting plate to fit closely with the mounting plate, and can improve the installation stability of the circuit breaker body. At the same time, the downward moving connecting plate can make the front end of the threaded rod located in the vertical through groove, and the initial positioning of the connecting plate and the circuit breaker body is achieved by the engagement between the fixing block and the mounting plate. The structure is simple and easy to operate.

[0016] After the connecting plate and the circuit breaker body are initially positioned, the positioning disc and the threaded rod can be manually rotated. Since the threaded rod is threadedly connected to the mounting plate, the threaded rod can drive the positioning disc to move backward when rotating, and control the positioning disc to enter the circular groove, so that the connecting plate can be snap-fitted and positioned to avoid unstable installation caused by the connecting plate moving up, thereby achieving stable installation of the circuit breaker body. Similarly, the threaded rod can be rotated to disengage the positioning disc from the circular groove, and then the connecting plate can be pulled upward to achieve quick disassembly of the circuit breaker body. This disassembly and assembly structure does not require the use of other tools, and the installation operation is simple, fast, and more practical. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The embodiments described below are only some of the embodiments of the present invention and do not represent all the embodiments consistent with the present invention. Now, in conjunction with the accompanying drawings, the exemplary embodiments are described as follows:

[0026] like Figure 1-5 As shown, the utility model is easy to operate the circuit breaker disassembly and assembly structure, which includes a mounting plate 1 and a circuit breaker body 8. A positioning groove 2 is opened in the middle of the front end of the mounting plate 1, and a plurality of slide grooves 3 are opened at equal intervals inside the bottom end of the mounting plate 1 along its length direction. Positioning components 4 are installed on the inner sides of the plurality of slide grooves 3. A connecting plate 5 is provided at the front end of the mounting plate 1, and a limiting groove 6 is opened at the bottom of the connecting plate 5. A fixing block 7 is fixedly connected to a side of the connecting plate 5 close to the mounting plate 1, and a circuit breaker body 8 is fixedly installed on a side of the connecting plate 5 away from the mounting plate 1.

[0027] On the basis of the above structure, the lengths of the positioning groove 2 and the mounting plate 1 are equal, and the plurality of slide grooves 3 and the plurality of positioning components 4 are arranged in a one-to-one correspondence.

[0028] In this embodiment, the positioning groove 2 is provided to facilitate the snap connection between the fixing block 7 and the mounting plate 1 .

[0029] Based on the above structure, the positioning assembly 4 includes a threaded rod 41, a positioning disc 42 and a block 43. The front end of the threaded rod 41 is fixedly connected to the positioning disc 42, and the rear end of the threaded rod 41 is sleeved with a block 43 on the outer bearing. The block 43 is slidably located on the inner side of the slide groove 3.

[0030] In this embodiment, the front-rear movement range of the threaded rod 41 can be limited by the arrangement of the block 43 and the slide groove 3 .

[0031] On the basis of the above structure, the threaded rod 41 is connected to the mounting plate 1 by threaded connection, and a protrusion is provided on the outer wall of the middle part of the front end of the positioning disc 42 .

[0032] In this embodiment, the connection plate 5 is conveniently positioned by the positioning disc 42 .

[0033] On the basis of the above structure, the limiting groove 6 includes a vertical through groove 61 and a circular groove 62 . The vertical through groove 61 is opened at the middle position of the bottom end of the connecting plate 5 , and a circular groove 62 is opened at the top of the vertical through groove 61 .

[0034] Based on the above structure, the thickness of the vertical through groove 61 is equal to the thickness of the connecting plate 5, the thickness of the circular groove 62 is only half of the thickness of the vertical through groove 61, the width of the vertical through groove 61 is equal to the diameter of the threaded rod 41, and the diameter of the circular groove 62 is equal to the diameter of the positioning disk 42.

[0035] In this embodiment, by rotating the threaded rod 41 to drive the positioning disc 42 to move backward and enter the circular groove 62, the connecting plate 5 can be positioned in a snap-fit ​​manner to achieve stable installation of the circuit breaker body 8.

[0036] On the basis of the above structure, the longitudinal section of the fixing block 7 is an inverted "L" shape, and the interface between the fixing block 7 and the positioning groove 2 is an inclined structure.

[0037] In this embodiment, since the interface surfaces of the fixing block 7 and the positioning groove 2 are both inclined structures, during the process of inserting the fixing block 7 into the positioning groove 2, the fixing block 7 can drive the connecting plate 5 to move backward, which is convenient for the connecting plate 5 to fit closely with the mounting plate 1, and can improve the installation stability of the circuit breaker body 8.

[0038] The working principle of the utility model is as follows:

[0039] When in use, first fix the mounting plate 1 in the distribution box. When installing the circuit breaker, first insert the fixing block 7 of the outer wall of the rear end of the connecting plate 5 into the positioning groove 2, and press the connecting plate 5 downward. Figure 2 As shown in , since the intersection surfaces of the fixing block 7 and the positioning groove 2 are both inclined structures, the fixing block 7 can drive the connecting plate 5 to move backward during the downward movement, which is convenient for the close fit between the connecting plate 5 and the mounting plate 1, and can improve the installation stability of the circuit breaker body 8. The engagement between the fixing block 7 and the mounting plate 1 facilitates the preliminary positioning of the connecting plate 5 and the circuit breaker body 8;

[0040] When the connecting plate 5 is moved down for installation, the front end of the threaded rod 41 can also be located in the vertical through groove 61. After the preliminary positioning, the positioning disc 42 and the threaded rod 41 can be manually rotated. Since the threaded rod 41 is threadedly connected to the mounting plate 1, the threaded rod 41 can drive the block 43 to move back stably in the slide groove 3 during rotation, and the positioning disc 42 can be moved back into the circular groove 62, so that the connecting plate 5 can be engaged and positioned, so as to avoid the connecting plate 5 moving up and causing unstable installation, and realize the stable installation of the circuit breaker body 8. Similarly, the threaded rod 41 can be rotated to make the positioning disc 42 move forward and disengage from the circular groove 62, and then the connecting plate 5 can be pulled upward to realize the quick disassembly of the circuit breaker body 8.

[0041] In summary, the disassembly and assembly structure does not require the use of other tools, the installation operation is simple and quick, the installation stability is high, and the practicality is stronger.

[0042] The above are only preferred specific embodiments of the utility model and are not intended to limit the protection scope of the utility model; any equivalent changes, modifications, substitutions and variations made by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the protection scope determined by the claims.
