Description

Technical Field

[0001] The utility model relates to the technical field of circuit breaker debugging, in particular to a debugging tool for opening and closing a circuit breaker. Background Art

[0002] During the production process of molded case circuit breakers, they need to be tested for opening and closing. However, since the circuit breaker is not fully assembled, it lacks a handle and cannot be tested for opening and closing. Therefore, a quick-disconnect debugging tool is needed to perform the opening and closing test on the molded case circuit breaker. After the test is completed, the debugging tool is quickly disassembled and the subsequent assembly of the molded case circuit breaker is completed. Utility Model Content

[0003] In view of the deficiencies in the prior art, the present invention provides a debugging tool for opening and closing a circuit breaker.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0020] like Figure 1 and Figure 2 As shown, the utility model discloses a debugging tool for opening and closing of circuit breakers, which is mainly used in the assembly process of molded case circuit breakers. After the assembly of the circuit breaker bracket is completed, opening and closing operations need to be performed to debug the position of the lever in the bracket. Since the handle has not been installed at this time, it is not easy to perform opening and closing operations. Therefore, the utility model discloses a debugging tool for quickly disconnecting and disconnecting from the lever at this stage. The installation and disassembly of the debugging tool are relatively convenient and can meet the opening and closing operations.

[0021] It is mainly composed of a base plate and a rotating buckle, wherein a buckle opposite to the rotating buckle is set at the bottom of the base plate, so that a corresponding clamping space is formed between the rotating buckle and the buckle. By rotating the rotating buckle, the lever can be placed into the clamping space and restricted by the buckle and the rotating buckle.

[0022] The bottom plate extends upward to form a handle, which is used as an operating part. By pulling the handle, the entire circuit breaker bracket is driven to move, completing the opening and closing actions.

[0023] The bottom plate 100 has a lower edge extending downwardly and is provided with a clip 120 for forming a limit fit with one end of the circuit breaker bracket 200. There can be two clips, which are arranged at intervals on the same edge of the bottom plate, and the size of the clip groove is adapted to the thickness of the lever, so that the lever can be easily inserted into the clip groove.

[0024] A rotating clip 300 is rotatably mounted on one side of the base plate 100. The rotating clip 300 is located opposite the clip 120, forming a clamping space 140 between the clip 120 and the clip 120 for clamping the circuit breaker bracket 200. The relatively rotatable clip can be moved away from or closer to the clip by rotation, thereby clamping the lever. This arrangement also makes assembly and disassembly more convenient.

[0025] The driving handle 110 is arranged perpendicular to the base plate 100 and is located on the upper side of the base plate 100. The driving handle 110 is provided with a baffle 400 that can slide along the axis of the driving handle 110. The baffle 400 has a first position that drives the rotating buckle 300 to move in the locking direction and a second position that releases the restriction on the rotating buckle 300.

[0026] The baffle mainly limits the movement of the rotating buckle away from the buckle when the rotating buckle clamps the lever. It is preferred that the baffle gives the rotating buckle a certain force to move in the direction of the buckle, thereby making the clamping more reliable. In some other embodiments, it can also be a force to maintain the clamping.

[0027] An elastic member 600 is provided between the baffle 400 and the base plate 100. The elastic member 600 is a spring. The function of the spring is to give the baffle a force to move upward. During operation, the baffle is pushed downward to compress the spring, and then the rotary buckle can be opened, which is convenient for installation. After the installation is completed, by releasing the hand pressing the baffle, the baffle will move upward under the action of the restoring force of the spring, thereby limiting the opening of the rotary buckle and maintaining the clamping state.

[0028] A positioning ring 500 is provided above the baffle 400 for limiting the maximum movement position of the baffle 400. The positioning ring is used to limit the maximum movement position of the baffle, ensuring that when the baffle moves to fit the positioning ring, the baffle can maintain the rotating buckle in a clamping state, avoiding excessive displacement that causes the baffle to be unable to limit the rotating buckle.

[0029] One end of the base plate 100 extends upward to form a support seat 130 , and the rotating buckle 300 is hingedly disposed on the support seat 130 . By being directly hinged to the base plate, the entire structure is simplified and the cost is reduced.

[0030] The rotating buckle 300 includes a hinge portion 310 , a pressing portion 320 extending upward from the hinge portion 310 , and a buckle portion 330 extending downward from the hinge portion 310 .

[0031] The buckle portion 330 and the pressing portion 320 are arranged in a staggered and parallel manner. The staggered and parallel manner can ensure that the buckle portion is placed on the outside of the bottom plate and the pressing portion is placed on the inside of the bottom plate, so that it can perform a better clamping operation.

[0032] The embodiments should not be regarded as limiting the present invention, but any improvements based on the spirit of the present invention should be within the scope of protection of the present invention.
