[0020] like Figure 1-2It is a schematic diagram of the structure of a novel control and protection switch in a preferred embodiment of the utility model. In this embodiment, a novel control and protection switch includes a switch body 1, a connecting cavity 14 is provided on the switch body 1, an operating handle 2 is arranged in the connecting cavity 14, and the operating handle 2 includes a handle 4, a connecting shaft 5, a fixed block 3 and a reset spring 7, an active cavity 6 is provided in the fixed block 3, the active cavity 6 is rotatably connected with the connecting shaft 5, and the connecting handle 4 is fixed on the top of the connecting shaft 5, the switch body 1 is operated by operating the handle 4, and a limiting block 15 is sleeved on the surface of the connecting shaft 5 at the cavity opening of the active cavity 6, which plays the role of limiting and supporting. At the same time, the reset spring 7 is sleeved on the surface of the connecting shaft 5, and the reset spring 7 is located between the connecting shaft 5 and the inner wall of the active cavity 6. The setting of this structure realizes the reset function; specifically, if you want to operate the switch body 1, the operator needs to press and then turn the handle 4 by hand to realize the control of the switch body 1, thereby replacing the problems caused by the traditional direct rotation of the handle 4, and effectively solving the problems raised in the background technology; combined with the setting of the utility model, the operating handle 2 of the switch has a locking function, which can effectively prevent misoperation when it is not rotated, and has higher safety; the operating handle 2 is firmly connected, compact in structure, convenient and quick to operate, and the product has a longer service life.
[0021] In this embodiment, a slot 8 is provided in the connecting cavity 14, and a collar 9 is provided in the connecting cavity 14 below the fixing block 3. A clamping block 10 is fixedly connected to the outer wall of the collar 9 at a position relative to the slot 8. The clamping block 10 is clamped in the slot 8. The above-mentioned structural design is utilized to realize that the operating handle 2 can be firmly fixedly installed on the switch body 1.
[0022] In this embodiment, the fixing block 3 and the collar 9 are designed as an integral structure, and the arrangement of this structure can increase the connection strength between the fixing block 3 and the collar 9, reduce the connection gap, and increase the service life.
[0023] In this embodiment, a rotation position 11 is opened on the inner wall of the ring 9, and a connection position 12 is opened on the inner wall of the ring 9 above the rotation position 11, and the connection position 12 is communicated with the rotation position 11, and a connection block 13 is fixedly connected below the outer wall of the connecting shaft 5, and the connection block 13 is movable between the connection position 12 and the rotation position 11. Combined with the above-mentioned structural design, when the handle 4 is pressed downward, the connecting shaft 5 is driven to move downward. As the connecting shaft 5 moves downward, the connection block 13 moves from the connection position 12 to the rotation position 11, thereby realizing the rotation of the handle 4, and the angle setting between the connection positions 12 is opened according to the limit positions of the closing and opening operations of the switch body 1.
[0024] In this embodiment, the connection block 13 is adapted to the connection position 12 , and its arrangement reduces the generation of gaps and better realizes the locking effect of the operating handle 2 .
[0025] How it works
[0026] During specific use, if the operator wants to operate the switch body 1, he needs to press the handle 4 to drive the connecting block 13 to move downward and away from the connecting position 12. After that, the connecting block 13 is at the rotating position 11. The handle 4 is rotated to rotate the connecting block 13 at the rotating position 11. After completing the operation of the switch body 1, the handle 4 is released. The reset spring 7 uses its own elasticity to push the connecting shaft 5 upward, driving the connecting block 13 to move from the rotating position 12 to the connecting position 11. If the operator wants to directly rotate the handle 4, the connecting block 13 will conflict with the connecting position 12 and cannot rotate, thereby realizing the self-locking function.
[0027] The above content is a further detailed description of the utility model in combination with specific implementation methods. It cannot be determined that the specific implementation of the utility model is limited to these descriptions. For ordinary technicians in the technical field to which the utility model belongs, without departing from the concept of the utility model, they can also make several simple deductions or substitutions, which should be regarded as belonging to the scope of protection determined by the claims submitted for the utility model.
