Clamping construction

Abstract

The invention discloses a locking structure which comprises a handle and a jacket of the handle; wherein, the same level straight line at one side of the handle is provided with two grooves, an interval is arranged in the middle of the two grooves, and two ribs that are corresponding to the grooves of the handle are arranged at the position where the jacket of the handle is corresponding to the handle. The deflection size of the jacket of the handle is smaller than that at the corresponding position of the handle. When being pushed into the handle, the jacket can keep elasticity, so as to be beneficial to the locking; the locking form of the structure is firm, and the assemble and disassembly are convenient; furthermore, the leap and radial wobble amplitude of the jacket of the handle on the handle can be effectively controlled. When the locking structure is used in a multipole assembly switch, the jacket can be taken off at any time even if the multipole switch is assembled and riveted. The locking form of the structure is convenient for assembly, when in operation, the jacket is just placed at the position corresponding to the handle and slightly pushed to be quickly locked; andwhether the jacket of the handle and the handle are in a good locking state can be well judged by the sound generated by the action of the locking.

Description

technical field [0001] The invention relates to a snap-fit ​​structure, in particular to a snap-fit ​​structure applied to equipment such as small circuit breakers, isolating switches and accessories thereof. Background technique [0002] On the multi-pole switch assembled and riveted by multiple single-pole switches, the existing snap-in form is that there are two pairs of square blind holes at the end of the handle, and the sheath is provided with symmetrical bosses inside the slot. When assembling and riveting the poles, it is necessary to insert the boss on one side of the sheath into the square hole of a switch handle installed, and then insert the square hole of the handle of the other switch into the other boss of the sheath. If it is a three-pole and four-pole platform, it is also assembled in sequence, and then riveted, and after the riveting, the sheath cannot be disassembled. Due to the linkage relationship of the handle, the user can only close the switch at the ...

If it is a three-pole and four-pole platform, it is also assembled in sequence, and then riveted, and after the riveting, the sheath cannot be disassembled. Due to the linkage relationship of the handle, the user can only close the switch at the same time when using multi-pole products. and disconnect
