DETAILED DESCRIPTION
[0022] The following will be combined with the attached embodiment of the utility model Figures 1-6 , clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of 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.
[0023] Embodiment 1:
[0024] like Figures 1 to 5 As shown, the utility model discloses a circuit breaker with good operability, including a circuit breaker body 1, a first control seat 3 and a second control seat 4. An operating handle 2 is rotatably arranged on the front side of the circuit breaker body 1, and the operating handle 2 includes a bend plate 21 for detachably connecting with the first control seat 3 and the second control seat 4. The user can select one of the first control seat 3 or the second control seat 4 to be installed on the bend plate 21 according to the usage scenario. The difference between the first control seat 3 and the second control seat 4 is that: Figure 1 As shown, the first control sleeve 3 is fixedly connected to an extended handle 31; Figure 2 As shown, an operation slot 41 is provided on the second control sleeve 4 .
[0025] The extended handle 31 on the first control sleeve 3 is convenient for the user to operate the extended handle 31 when the operating handle 2 is in an inaccessible position. The operator can directly turn the extended handle 31 by hand to control the operating handle 2 to open and close the gate. The operation card slot 41 on the second control sleeve 4 can be used for the user to insert a wooden pole or other long pole tool into it when the user uses a wooden pole or other long pole tool to operate, so as to increase the user's operating distance. The operation card slot 41 is convenient for the user to use a wooden pole or other tool to turn the operating handle 2. The specific choice of whether to use the first control sleeve 3 or the second control sleeve 4 can be made by the user according to the actual usage scenario and his own operating habits.
[0026] like Figure 3 andFigure 4 As shown in Figure 4 , the specific structure for the first control sleeve seat 3 and the second control sleeve seat 4 to be detachably connected to the lever plate 21 is as follows: Connecting grooves 7 are respectively formed through the first control sleeve seat 3 and the second control sleeve seat 4 toward the right side, and the lever plate 21 can be detachably connected in the connecting grooves 7. Specifically, the lever plate 21 is in the shape of a cross strip, and the connecting grooves 7 are adapted to the lever plate 21 and are used for the lever plate 21 to be slidably inserted therein.
[0027] Furthermore, both the first control sleeve seat 3 and the second control sleeve seat 4 are provided with a fixing mechanism at the right end of the connecting groove 7 for preventing the lever plate 21 from disengaging from the connecting groove 7 toward the right.
[0028] In this embodiment, the fixing mechanism includes a rubber plug 5, which is press-fitted into the opening at the right end of the connecting groove 7, thereby preventing the lever plate 21 from disengaging from the connecting groove 7 and maintaining the structural reliability of the connection between the first control sleeve seat 3 and the second control sleeve seat 4 on the lever plate 21.
[0029] Among them, the length direction of the operation card slot 41 extends toward the left and right ends of the second control sleeve seat 4. Such a structure of the operation card slot 41 provides a large space for insertion, facilitating the insertion of tools. In addition, a circular card slot 42 is formed in the middle of the operation card slot 41, and the circular card slot 42 is convenient for inserting a circular wooden rod tool.
[0030] In addition, as Figure 5 shown, in the present utility model, a third control sleeve seat 8 is further included. The third control sleeve seat 8 is made of wear-resistant insulating material. The connection manner between the third control sleeve seat 8 and the lever plate 21 is the same as that of the first control sleeve seat 3 and the second control sleeve seat 4. The third control sleeve seat 8 is used in scenarios where the position is appropriate and the space is not narrow. The third control sleeve seat 8 can be made of rubber or polyurethane, which is insulating and wear-resistant and can be used to improve the safety of operators.
[0031] Embodiment 2:
[0032] Embodiment 2 is basically the same as Embodiment 1, except that the fixing mechanism in Embodiment 2 is not the rubber plug 5. The fixing mechanism in Embodiment 2 includes a screw 61 and a gasket 62. As Figure 6 shown, a threaded hole 22 is formed at the right end of the lever plate 21, and the gasket 62 is located outside the connecting groove 7. The screw 61 passes through the gasket 62 and is threadedly connected to the threaded hole 22, and this structure has a firm fixing effect.
[0033] It should be noted that the terms used in the present utility model, such as "front", "rear", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. This is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation on the protection scope of the present utility model.
[0034] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
