Problems solved by technology

However, this structure also has the following disadvantages: the rocker arm of the handle moves linearly through two parallel long shaft holes to operate the locking member, but the two long shaft holes are prone to loosening when rotating
After the handle rocker arm drives the connecting rod to rotate, the handle rocker arm can easily move in the opposite direction with a small gap, making the positioning control of the handle rocker arm itself unstable, causing troubles for users, and even affecting the opening and closing of the circuit breaker

Embodiment 1

[0036] Such as figure 1 and figure 2 As shown, this embodiment provides an opening and closing handle mechanism of a plug-in circuit breaker, which is installed in a plug-in circuit breaker. The plug-in circuit breaker also includes a housing and an operating mechanism. The opening and closing handle mechanism specifically includes a handle rocker arm 1 and a connecting rod 2 , and the handle rocker arm 1 is hinged to the housing of the plug-in circuit breaker through a rotating shaft 4 . The connecting rod 2 is a rod member bent at both ends, the right end of which is bent into a connecting end 21 for connecting with the handle rocker arm 1 , and a bending portion 22 is also provided at the end of the connecting end 21 . The bending at the left end of the connecting rod 2 is connected to the operating mechanism, and the operating mechanism is deformed by toggling the rocker arm 1 of the handle, thereby changing the opening and closing state of the circuit breaker.

Embodiment 2

[0045] Such as Figure 8 As shown, the main difference between the present embodiment and the first embodiment is that the braking part in this embodiment is only a limiting protrusion 13 , and the limiting protrusion 13 is installed on the side wall of the rocker arm 1 of the handle.

[0046] Such as Figure 9 As shown, when the plug-in circuit breaker needs to be closed, the handle rocker arm 1 rotates clockwise along the rotating shaft 4, so that the bending part 22 rotates counterclockwise relative to the handle rocker arm 1 until it abuts against the brake block 13, thereby The rocker arm 1 of the handle and the connecting rod 2 form a lock with each other, and no relative movement occurs.

[0047] Such as Figure 10 As shown, when the circuit breaker needs to be opened, the handle rocker arm 1 rotates counterclockwise along the rotating shaft 4, so that the bending part 22 is separated from the brake block 13 by a certain distance, thereby releasing the mutual restrict...

Abstract

The invention relates to an opening and closing handle mechanism and a plug-in circuit breaker. The handle mechanism comprises a handle rocker arm and a connecting rod; the handle rocker arm is hingedto a shell of the plug-in circuit breaker through a rotating shaft. The handle rocker arm is connected with an operating mechanism in the plug-in circuit breaker through a connecting rod; the handlerocker arm is provided with a first long-strip-shaped shaft hole and a second long-strip-shaped shaft hole. The rotating shaft is installed in the first long-strip-shaped shaft hole, the connecting end of the connecting rod penetrates into the second long-strip-shaped shaft hole, a bent part is arranged at the connecting end, a brake part is arranged on the side wall of one side of the handle rocker arm, and after the connecting end penetrates through the second long-strip-shaped shaft hole, the bent part of the connecting end is located on the side wall with the brake part. Compared with theprior art, in the opening and closing process of the plug-in circuit breaker, the bent part rotates at the brake part without interference; and after closing, the bent part and the brake part are mutually limited, so that the arm rocker arm is fixed and static, and the stability of the arm rocker arm after closing is ensured.

Description

technical field [0001] The invention relates to the field of plug-in circuit breakers, in particular to an opening and closing handle mechanism and a plug-in circuit breaker. Background technique [0002] In recent years, plug-in circuit breakers have become more and more widely used, especially with the rapid development of the 5G industry, the demand for 5G cabinets is increasing, and the plug-in circuit breakers used in conjunction with them have attracted more and more attention from manufacturers. [0003] The Chinese invention application with publication number CN 107993900 A discloses a plug-in miniature circuit breaker. The invention application is the most common plug-in circuit breaker on the market. The plug-in circuit breaker adopts a button structure. When the button is pressed, the circuit breaker closes; when the button is pulled out, the circuit breaker opens. However, this structure is prone to the problem of misoperation of the circuit breaker coming out...
