Description

Spring rotary switch

Technical Field

the utility model belongs to the technical field of the switch, a spring rotary switch is related to.

Background

the common switch is generally a key lock, and the key is used for realizing the rotation unlocking of the switch, so that the unlocking mode is troublesome.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a spring rotary switch realizes that the switch is rotatory to be unblanked, and can automatic re-setting through pressing the switch downwards.

In order to achieve the above purpose, the utility model adopts the technical scheme that:

A spring rotary switch comprises a switch base with a step hole inside and a switch column with a cap head at the head, wherein the switch column penetrates through the step hole small hole of the switch base, the end part of the switch column is connected with a locking plate, and a spring is arranged between the cap head at the other end and the step of the switch base;

The side wall of the small hole of the stepped hole is provided with a spiral groove, and the side wall below the switch column is provided with a spiral pin matched with the spiral groove.

The utility model discloses a cap head of switch post is pressed downwards, behind the switch post atress, the spring pushes down, and the spiral pin of switch post below lateral wall moves along the helicla flute rotation downstream of the inside step hole aperture lateral wall of switch seat, and the locking plate that the switch post drove its tip simultaneously is rotatory, realizes that the locking plate unblanks. When the cap head of the switch column is released, the spring rebounds, the spiral pin of the switch column rotates and moves upwards along the spiral groove of the switch seat, and the locking plate connected with the end part of the spiral pin rotates and resets along with the spiral groove.

fig. 1 is a schematic structural view of the present invention;

Fig. 2 is a schematic structural diagram of a switch column in the present invention;

Fig. 3 is a schematic partial cross-sectional view of the switch base of the present invention.

Detailed Description

The invention is described in further detail below with reference to the drawings and specific examples.

As shown in fig. 1-3, a spring rotary switch comprises a switch base 1 with a step hole inside and a switch column 2 with a cap head 2.1 at the head, wherein the switch column 2 penetrates through a small hole 1.1 of the step hole of the switch base 1, the end part of the switch column is fixedly connected with a locking plate 4 through a bolt 5, and a spring 3 is arranged between the cap head 2.1 at the other end and the step 1.3 of the switch base 1;

The side wall of a small hole 1.1 of the stepped hole is provided with a spiral groove 1.2, and the side wall below the switch column 2 is provided with a spiral pin 2.2 matched with the spiral groove.

The cap head 2.1 of the switch column 2 is pressed downwards, after the switch column 2 is stressed, the spring 3 is pressed downwards, the spiral pin 2.2 on the side wall below the switch column 2 rotates along the spiral groove 1.2 on the side wall of the small hole 1.1 of the step hole in the switch base 1 and moves downwards, and meanwhile, the switch column 2 drives the locking plate 4 on the end part to rotate, so that the locking plate 4 is unlocked. The cap head 2.1 of the switch column 2 is released, the spring 3 rebounds and resets, the spiral pin 2.2 of the switch column 2 rotates and moves upwards along the spiral groove 1.2 of the switch seat 1, and the locking piece 4 connected with the end part rotates and resets along with the spiral pin.

Although the present invention has been disclosed in detail with reference to the accompanying drawings, it is to be understood that such description is merely illustrative and not restrictive of the application of the present invention. The scope of the invention is defined by the appended claims and may include various modifications, adaptations and equivalents of the invention without departing from its scope and spirit.

Claims (1)
