This technical solution relates to the technical field of circuit breakers, specifically a circuit breaker that is convenient for wiring, comprising: a body, including a circuit breaker body, on the surface of which a connection line is installed; a wiring mechanism, including a screw, which is movably connected to the surface of the circuit breaker body, and which fixes the connection line on the circuit breaker body, and on the surface of which a first limiting column is fixedly connected, and on the surface of which a first limiting ring is movably connected, and on the surface of which a connecting rod is fixedly connected. The utility model uses screws, first limiting columns, first limiting rings, connecting rods, fixed rods, second limiting rings, and second limiting columns, so that when installing and removing the connecting line, the screws can be on the surface of the circuit breaker body, making the wiring process more convenient, and there will be no falling off and no matching screws can be found for wiring, thereby improving wiring efficiency;

[0004] However, when wiring the circuit breaker of the prior art solution, a tool is needed to tighten the screws to fix the connection line on the circuit breaker. If the installer does not have the tool, the circuit breaker cannot be wired, which makes the wiring of the circuit breaker inconvenient.

[0005] In order to solve the above problems, the present application proposes a circuit breaker that is convenient for wiring. Utility Model Content

[0006] The utility model aims to provide a circuit breaker with convenient wiring, which is mainly used to solve the problem that the existing circuit breaker needs to use tools to tighten screws to fix the connection line on the circuit breaker, thereby causing inconvenience in wiring the circuit breaker.

[0007] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0008] A circuit breaker convenient for wiring comprises a circuit breaker body and a connecting line. A sliding cavity matching the connecting line is provided on the circuit breaker body, a moving block is slidably connected inside the sliding cavity, a threaded rod is fixedly connected to one side of the moving block, a knob is rotatably connected to the opening of the sliding cavity on the circuit breaker body, a threaded hole matching the threaded rod is provided on one side of the knob close to the circuit breaker body, and an anti-loosening component is slidably connected to one side of the knob on the circuit breaker body.

[0009] The working principle and beneficial effects of the utility model:

[0010] 1. Working principle: When wiring the circuit breaker body, insert the connecting line into the circuit breaker body, and then turn the knob to make the threaded rod connected to it drive the moving block to move in the direction of the connecting line. When the moving block presses the connecting line tightly, stop turning the knob, fix the knob through the anti-loosening component on one side of the circuit breaker body, and the circuit breaker can be used normally.

[0011] 2. Beneficial effect: By turning the knob, the threaded rod can drive the moving block to move and tighten the connection line. The advantage of this arrangement is that when the circuit breaker body is connected, people can manually turn the knob to fix the connection line. The anti-loosening component set on one side of the circuit breaker body can better fix the knob, thereby effectively preventing the connection line from loosening due to people accidentally touching the knob during the use of the circuit breaker, thereby making the circuit breaker more stable when in use.

[0012] Preferably, the anti-loosening assembly includes a rectangular block slidably connected to one side of the knob on the circuit breaker body, a guide block fixedly connected to one side of the rectangular block close to the circuit breaker body, a guide groove matching the guide block is provided on the circuit breaker body, an insert block is fixedly connected to one side of the rectangular block close to the knob, a plurality of slots matching the insert block are provided on the outer wall of the knob, and the slots are equidistantly distributed on the outer wall of the knob in a circular array. After the connecting line is inserted into the inside of the circuit breaker body, the moving block presses the connecting line tightly when the knob is turned, and then the rectangular block is slid to move it toward the direction of the knob. When the insert block on the rectangular block is inserted into the slot on the knob, the knob can be better fixed, thereby effectively preventing the connecting line from loosening due to people accidentally touching the knob during use of the circuit breaker. When the connecting line needs to be removed, the rectangular block is moved in a direction away from the knob. When the insert block is out of the slot, the knob can be rotated in the opposite direction to move the moving block in a direction away from the connecting line, and then the connecting line can be pulled to separate it from the circuit breaker body, thereby making the circuit breaker more practical.

[0013] Preferably, a plurality of T-shaped blocks are fixedly connected to one side of the knob close to the circuit breaker body, and the T-shaped blocks are equidistantly distributed on the T-shaped blocks in a circular array, and an annular groove matching the T-shaped blocks is provided on the circuit breaker body. When the knob is turned, the plurality of T-shaped blocks arranged on one side of the knob and the annular groove provided on the circuit breaker body can better limit and guide the knob, thereby making the knob more stable when rotating.

[0014] Preferably, one end of the plug block away from the rectangular block is fixedly connected to a magnet block, and the inner wall of the slot is fixedly connected to an iron sheet attracted to the magnet block. After the plug block is inserted into the slot, the magnet block at one end of the plug block is attracted to the iron sheet inside the slot, which can better fix the plug block. This can effectively prevent the plug block from detaching from the slot during the use of the circuit breaker, thereby further improving the stability of the circuit breaker during use.

[0015] Preferably, one side of the T-shaped block is rotatably connected to a plurality of ball bearings, and the ball bearings are equidistantly distributed on the T-shaped block. When the knob is turned, the T-shaped block will slide inside the annular groove. The plurality of ball bearings arranged on one side of the T-shaped block can effectively reduce the friction between the T-shaped block and the inner wall of the annular groove, thereby making it smoother for people to turn the knob.

[0016] Preferably, the corners at the slot opening are all rounded. By setting the corners at the slot opening to be rounded, it is easier to insert the plug into the slot.

[0017] Preferably, arc grooves are provided at the top and bottom of the rectangular block, and rubber pads are fixedly connected to the inner walls of the arc grooves. The arc grooves provided at the top and bottom of the rectangular block can make it easier and more labor-saving for people to pull the rectangular block. The rubber pads provided on the inner walls of the arc grooves can increase the friction between the staff's hands and the rectangular block, thereby effectively preventing people's hands from slipping when pulling the rectangular block.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-4 A circuit breaker for convenient wiring comprises a circuit breaker body 1 and a connection line 2. A sliding cavity 3 matching the connection line 2 is provided on the circuit breaker body 1. A moving block 4 is slidably connected inside the sliding cavity 3. A threaded rod 5 is fixedly connected to one side of the moving block 4. A knob 6 is rotatably connected to the opening of the sliding cavity 3 on the circuit breaker body 1. A threaded hole 7 matching the threaded rod 5 is provided on the side of the knob 6 close to the circuit breaker body 1. When the circuit breaker body 1 is wired, the connection line 2 is inserted into the circuit breaker body 1. Then, by rotating the knob 6, the threaded rod 5 threadedly connected thereto can drive the moving block 4 to move in the direction of the connection line 2. After the moving block 4 presses the connection line 2 tightly, the connection line 2 can be fixed well. The knob 6 is fixedly connected to the side of the circuit breaker body 1. A T-shaped block 13 is provided, and the T-shaped blocks 13 are evenly distributed on the T-shaped block 13 in a circular array. An annular groove 14 matching the T-shaped block 13 is provided on the circuit breaker body 1, which can play a better role in limiting and guiding the knob 6, so that the knob 6 has higher stability when rotating. A plurality of balls 17 are rotatably connected to one side of the T-shaped block 13, and the balls 17 are evenly distributed on the T-shaped block 13, which can effectively reduce the friction between the T-shaped block 13 and the inner wall of the annular groove 14, so that people can turn the knob 6 more smoothly. An anti-loosening component is slidably connected to one side of the knob 6 on the circuit breaker body 1. After the moving block 4 presses the connection line 2 tightly, the knob 6 stops rotating, and the knob 6 is fixed by the anti-loosening component on one side of the circuit breaker body 1, and the circuit breaker can be used normally.

[0025] like Figure 2 and Figure 4As shown, the anti-loosening assembly includes a rectangular block 8 slidably connected to one side of the knob 6 on the circuit breaker body 1, arc grooves are provided on the top and bottom of the rectangular block 8, and a rubber pad is fixedly connected to the inner wall of the arc groove, a guide block 9 is fixedly connected to the side of the rectangular block 8 close to the circuit breaker body 1, a guide groove 10 matching the guide block 9 is provided on the circuit breaker body 1, an insert block 11 is fixedly connected to the side of the rectangular block 8 close to the knob 6, a plurality of slots 12 matching the insert block 11 are provided on the outer wall of the knob 6, and the slots 12 are equidistantly distributed on the outer wall of the knob 6 in a circular array, after the connecting line 2 is inserted into the circuit breaker body 1, the moving block 4 presses the connecting line 2 when the knob 6 is turned, and then the rectangular block 8 is slid to move it toward the knob 6, when the insert block 11 on the rectangular block 8 is inserted into the slot 12 on the knob 6, the knob 6 can be better fixed, thereby effectively preventing the knob from being accidentally touched by people during the use of the circuit breaker. 6 causes the connecting line 2 to loosen. When the connecting line 2 needs to be removed, the rectangular block 8 is moved in the direction away from the knob 6. When the plug-in block 11 is separated from the slot 12, the knob 6 can be rotated in the opposite direction to move the movable block 4 in the direction away from the connecting line 2, and then the connecting line 2 can be pulled to separate it from the circuit breaker body 1, thereby making the circuit breaker more practical. The corners at the opening of the slot 12 are all rounded, which can make it more convenient to insert the plug-in block 11 into the slot 12. The end of the plug-in block 11 away from the rectangular block 8 is fixedly connected with a magnet block 15, and the inner wall of the slot 12 is fixedly connected with an iron sheet 16 attracted to the magnet block 15. After the plug-in block 11 is inserted into the slot 12, the magnet block 15 at one end of the plug-in block 11 is attracted to the iron sheet 16 inside the slot 12, which can play a good fixing effect on the plug-in block 11. This can effectively prevent the plug-in block 11 from being separated from the slot 12 during the use of the circuit breaker, thereby further improving the stability of the circuit breaker during use.

[0026] From the above, it can be seen that the specific implementation of the utility model is as follows:

[0027] When the circuit breaker body 1 is connected, the connecting line 2 is inserted into the circuit breaker body 1, and then the knob 6 is rotated to make the threaded rod 5 threadedly connected thereto drive the moving block 4 to move in the direction of the connecting line 2, so that the moving block 4 presses the connecting line 2 tightly, and the rectangular block 8 is slid to move it in the direction of the knob 6. When the plug-in block 11 on the rectangular block 8 is inserted into the slot 12 on the knob 6, the magnet block 15 at one end of the plug-in block 11 is attracted to the iron sheet 16 in the slot 12, so that the knob 6 can be fixed well, thereby effectively preventing the connecting line 2 from loosening due to people accidentally touching the knob 6 during the use of the circuit breaker. At this time, the circuit breaker can be used normally. When the connecting line 2 needs to be disassembled, the rectangular block 8 is moved away from the knob 6. When the plug-in block 11 is separated from the slot 12, the knob 6 can be rotated in the opposite direction to move the moving block 4 in the direction away from the connecting line 2, and then the connecting line 2 can be pulled to separate it from the circuit breaker body 1, thereby making the circuit breaker more practical.
