Detailed Description

In order to make the above objects, features and advantages of the present invention more clearly understood, the present invention will be further described with reference to the accompanying drawings and examples. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the present invention is not limited to the limitations set forth in the following description of the specific embodiments.

In a first embodiment, please refer to fig. 1-4, the present invention provides a technical solution: the utility model provides a miniature circuit breaker easy to assemble, including circuit breaker body 1, spacing hole 2 has been seted up to one side of circuit breaker body 1, logical groove 3 has still been seted up to one side that the inside of circuit breaker body 1 is located spacing hole 2, circuit breaker body 1 has spacing stick 4 for one side fixed mounting of spacing hole 2, spring an 5 is equipped with admittedly to the inside of spacing stick 4, spring an 5's top fixedly connected with bullet piece 6, the both sides of bullet piece 6 are the arc, 6 symmetric distribution of bullet piece are located four corners position department in one side of circuit breaker body 1, through setting up multiunit bullet piece 6, the fastness after connecting between the circuit breaker body 1 has been improved.

Please refer to fig. 4, rubber washer 7 is equipped with admittedly on the surface of spacing stick 4, through setting up rubber washer 7, the effect of increasing spacing stick 4 frictional force has been played, the stability of spacing stick 4 when circuit breaker body 1 has been improved, simultaneously when rubber washer 7 gets into spacing hole 2 inside, deformation then can appear in rubber washer 7 this moment, still including the driving lever 8 that opens circuit, the driving lever 8 that opens circuit sets up on the surface of circuit breaker body 1, through setting up the driving lever 8 that opens circuit, the circuit switch-on when the gear was dialled to last gear to the driving lever 8 that opens circuit, circuit disconnection when dialling gear down.

In a second embodiment, referring to fig. 5-8, an auxiliary device is disposed on a surface of the circuit breaker body 1 near the trip lever 8, the auxiliary device includes a connecting block 9, a rotating rod 10 is rotatably connected to a top surface of the connecting block 9, a knob 14 is fixedly mounted at a top end of the rotating rod 10, and by setting the knob 14, people can conveniently rotate the rotating rod 10, so that the practicability of the rotating rod 10 is improved.

Referring to fig. 5-8, a limiting plate 11 is fixedly mounted on one side of the rotating rod 10, a spring b12 is fixedly mounted at a position, located at one side, inside the rotating rod 10, a positioning bead 13 is fixedly connected to one side of the spring b12, a through hole 15 is formed at a position, located at the positioning bead 13, on one side of the connecting block 9, the positioning bead 13 penetrates through the through hole 15, the positioning bead 13 is slidably connected with the through hole 15, and the through hole 15 is arranged to play a role of limiting the positioning bead 13, so that the positioning bead 13 can prevent the rotating rod 10 from rotating.

The working principle is as follows: through setting up circuit breaker body 1, spacing hole 2, lead to groove 3, spacing stick 4, spring a5 and elastic block 6, in the installation of adjacent circuit breaker body 1, people only need insert spacing stick 4 on single circuit breaker body 1 in the spacing hole 2 that another circuit breaker body 1 one side was seted up, because the shape of elastic block 6 is the arc, when elastic block 6 and spacing hole 2 inner wall laminating of spacing stick 4 one side, elastic block 6 then can drive spring a5 locking to inside spacing stick 4 this moment, when spacing stick 4 can't continue to move, at this moment, elastic block 6 and logical groove 3 coincidence, spring a5 then drives elastic block 6 and runs through logical groove 3 inside, the effect of location circuit breaker body 1 has been played, when people need separate circuit breaker body 1, only need outwards stimulate circuit breaker body 1 can, through setting up auxiliary device, because circuit breaker body 1 usually utilizes deflector rod 8 control circuit that opens and breaks when the knob 13 and drives deflector rod 13 and the deflector rod 11 rotates the deflector rod 12 and the deflector rod 13 rotates the deflector rod 12 and the fixed position the deflector rod 12 and then can not rotate the deflector rod 12 when people move the deflector rod 12 and the effect of fixing, and the deflector rod can not rotate the deflector rod 12 when people's turn on the deflector rod.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in other forms, and any person skilled in the art may use the above-mentioned technical contents to change or modify the equivalent embodiment into equivalent changes and apply to other fields, but any simple modification, equivalent change and modification made to the above embodiments according to the technical matters of the present invention will still fall within the protection scope of the technical solution of the present invention.
