Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The utility model will be described in detail with reference to fig. 1 and 2, and the key switch type quick release lug comprises a pin 1, a bracket cover 2, a base 3 and a bracket 4, wherein the two pins 1 are respectively movably arranged in a hollow tube at the front part of the base 3, the heads of the two pins 1 are in contact with the conical head of the bracket 4, the bracket cover 2 is arranged above the base 3 in a turnover manner, a key 5 is arranged on the bracket cover 2, the bracket 4 is vertically arranged with a first elastic part 6, and when the key 5 is pressed down, the key 5 pushes the bracket 4 to move towards a direction of compressing a second elastic part 7, so that the pin 1 is driven to shrink in the hollow tube. The key switch type quick-release lug has the characteristics of simple structure, easiness in assembly, convenience in operation, strong compatibility and the like.

A working principle of a key switch type quick-release lug is as follows: the key 5 moves downwards to push the support 4 to move towards the direction of compressing the second elastic part 7, at the moment, the support 4 moves backwards, and under the action of the first elastic part 6, the 2 pins 1 move oppositely in the hollow tube to finish the contraction action of the pins 1; when the external force applied to the key 5 disappears, the key 5 bounces. The internal force of the second elastic part 7 is released, the second elastic part 7 pushes the bracket 4 to the initial position, so that the 2 pins 1 are driven to move outwards and axially in the hollow tube, and the extending action of the pins 1 is completed. When no pressure is applied to the key 5, the key 5 is maintained in the initial state, and the first elastic member 6 is maintained in the initial state, so that the pin 1 is positioned in the extended state.

In a specific embodiment, the hollow tube and the pin 1 are both cylindrical structures, and the two cylindrical pins 1 are fixed in the cylindrical hollow tube, so that the pin 1 has the freedom of axial reciprocating motion, and the pin 1 can do contraction or extension motion along the axial direction of the hollow tube.

In a specific embodiment, the support 4 comprises a tapered head and a cross bar, the tapered head and the cross bar are distributed in front and at the back to form a T-shaped structure, and the cross bar is provided with 2 inclined planes. The bottom of button 5 is provided with 2 inclined plane grooves, and 2 inclined plane grooves are fixed with 2 inclined planes of horizontal pole cooperations.

In a specific embodiment, the elastic members include a first elastic member 6 and a second elastic member 7, and the first elastic member 6 and the second elastic member 7 are U-shaped springs. The 2 pins 1 are respectively sleeved with a first elastic component 6, and the 2 pins 1 are coaxially arranged. The key 5 moves downwards to push the bracket 4 to move towards the direction of compressing the second elastic component 7, thereby driving the pin 1 to move inwards. One end of the second elastic part 7 is abutted against the cross bar of the bracket 4.

In a specific embodiment, a key slot is arranged on the bracket cover 2, and the key 5 can be movably arranged in the key slot up and down. The arrangement of the keys 5 facilitates the installation and the disassembly of the ear, and the watchband can be assembled and disassembled without the help of special tools or nails.
