Example 1

A knife switch with removable mounting structure as shown in fig. 1-6, comprising a base plate 10, a contact assembly 20 and a handle member 30, wherein the handle member 30 is connected to the contact assembly 20, and the handle member 30 comprises an insulating block 40, a base 170 that is snap-fitted to the insulating block 40, and a handle portion 50 that is removably fitted to the base 170.

The two side parts of the base 170 are provided with clamping grooves 60, the base 170 is of a C-shaped structure, the lower part of the base 170 is provided with a buckle 70 matched with the clamping grooves 60, the handle 50 comprises a spherical part 200 and a connecting column 80, and the base 170 is provided with a slot 90 matched with the connecting column 80.

The base 170 is directly inserted and assembled with the buckle 70 through the clamping groove 60 arranged on the long side of the insulating block 40, and compared with the prior art in which the handle is connected through threads, the buckle 70 is more rapid and convenient to connect and easy to detach. And the threads are easy to damage and irreversible and quite unreliable.

The snap 70 is disposed on the inner sidewall of the bottom of the base 170, and the C-shaped opening of the base 170 is slightly smaller than the width of the base 170, which forms an interference fit between the base 170 and the insulating block 40, greatly increasing the strength and reliability of the connection of the base 170 and the insulating block 40.

Specifically, the slot 90 is disposed on the top surface of the base 170, two sides of the slot 90 are further provided with a latch 100 and a cavity 120 for accommodating the latch 100, the slot 90 is provided with a through slot 160 for communicating the slot 90 with the cavity 120, the latch 100 includes an elastic portion 130 and a head 110, one side of the head 110 is provided with a stopper 140 extending into the slot 90 through the through slot 160, and a groove 150 matched with the stopper 140 is disposed on a side of the connecting post 80.

The top surface of the limiting block 140 is an inclined surface, the bottom surface is a horizontal surface, the elastic portion 130 and the head portion 110 are integrally formed, and the whole lock latch 100 is made of nylon 66. The number of the accommodating chambers 120 and the number of the locking elements 100 are two, at least one positioning column 180 is arranged on the bottom surface of the base 170 connected with the insulating block 40, positioning grooves 190 matched with the positioning columns 180 are arranged on the top of the base 170, and the number of the positioning grooves 190 is the same as that of the positioning columns 180 and the positions of the positioning grooves correspond to each other.

The top surface of the stopper 140 is a downward inclined surface, which makes the connection post 80 of the handle portion 50 move downward against the lock block when being inserted, and since the force between the connection post 80 and the stopper 140 acts perpendicular to the inclined surface, and the lock block has a certain elasticity, the lock block is compressed a certain distance toward the cavity 120, and the stopper 140 is also compressed a certain distance toward the through groove 160. After the groove 150 of the connecting post 80 and the stopper 140 are at the same level, the stopper 140 pops up to cooperate with the groove 150.

Specifically, the positioning column 180 and the base 170 are integrally formed, and the depth of the cavity 120 is greater than or equal to the depth of the through groove 160. The clamping groove 60 is communicated with two sides of the insulating block 40, and the base 170 and the handle are made of insulating materials.

The diameter of the connecting column 80 is slightly larger than that of the slot 90, the handle part 50 can be fixed by direct insertion or limiting of the latch 100, the handle is easy to mount and dismount, the replacement is quite reliable, the mounting space is distributed reasonably, and compared with the traditional threaded column mounting, the handle is more reliable.

The above examples are merely illustrative of the preferred embodiments of the present utility model and are not intended to limit the spirit and scope of the present utility model. Various modifications and improvements of the technical scheme of the present utility model will fall within the protection scope of the present utility model without departing from the design concept of the present utility model, and the technical content of the present utility model is fully described in the claims.
