Through adopting above-mentioned technical scheme, the slider runs through the casing and is convenient for operating personnel control slider, and the stopper is used for making slider and casing difficult separation.

Optionally, the reset member is a spring.

Through adopting above-mentioned technical scheme, spring position market purchase piece is convenient for acquire and use.

Optionally, the end of the ejector rod is arc-shaped.

Through adopting above-mentioned technical scheme for the ejector pin is when running through the chain body, and the difficult chain body that wears.

Optionally, the end edge of the sliding block located outside the shell is arc-shaped.

Through adopting above-mentioned technical scheme for when pressing the sliding block, operating personnel is difficult for the fish tail.

Optionally, the spring buckle is mounted at one end of the chain body.

By adopting the technical scheme, the adjusting range of the chain body is larger.

Optionally, the chain body is formed by connecting a plurality of chain loops end to end.

By adopting the technical scheme, a structural mode of the chain body is provided specifically but not restrictively, and the chain body can have a certain rotation function without unique explanation.

Optionally, the chain ring is circular and has two narrow ends and a wide middle.

Through adopting above-mentioned technical scheme, the joint cooperation of the buckle of being convenient for and chain circle.

In summary, the present application includes at least one of the following beneficial technical effects:

according to the spring type chain fixing structure, the ejector rod penetrates through the chain body to tightly support the chain body, so that the chain body is not prone to shaking relative to the spring fastener, and the chain body is not prone to abrasion;

the utility model provides a spring chain fixed knot constructs's chain circle is convenient for buckle and the joint cooperation of chain circle.

Description of reference numerals:

1. a chain body; 11. a chain loop; 2. a spring buckle; 21. a housing; 211. the clamping cavity; 22. a sliding block; 221. a limiting block; 222. a through hole; 23. a reset member; 24. and a push rod.

Detailed Description

The present application is described in further detail below with reference to figures 1-2.

The embodiment of the application discloses spring chain fixed knot constructs. Referring to fig. 1, a spring type chain fixing structure includes a chain body 1 and a spring buckle 2.

Wherein, the chain body 1 is formed by a plurality of chain rings 11 end to end, and chain ring 11 is the ring form and the narrow centre in both ends is wide so that buckle and the joint cooperation of chain ring 11, and snak link 2 is installed in the one end of the chain body 1 so that the control range of the chain body 1 is bigger.

The structure of the snap 2 is described in detail below.

The spring buckle 2 comprises a shell 21, a clamping cavity 211 is formed in the shell 21 in a hollow mode, a sliding block 22 is connected to the shell 21 in a sliding mode, a reset piece 23 is installed between the sliding block 22 and the inner wall of the shell 21, a through hole 222 is formed in the sliding block 22, and a push rod 24 is arranged inside the through hole 222. Wherein, the restoring member 23 can be a spring, which is convenient to obtain and use because the spring is commercially available.

The sliding block 22 penetrates through the shell 21, and a limiting block 221 is arranged on the side wall of the sliding block 22. The sliding block 22 penetrates through the shell 21, so that an operator can control the sliding block 22 conveniently, and the limiting block 221 is used for enabling the sliding block 22 to be not separated from the shell 21 easily.

In this embodiment, the end of the top rod 24 is arc-shaped, so that the top rod 24 is not easy to wear the chain body 1 when penetrating through the chain body 1.

In order to prevent the operator from being scratched when the sliding block 22 is pressed, further, the edge of the end of the sliding block 22 located outside the housing 21 is arc-shaped,

the implementation principle of the spring type chain fixing structure in the embodiment of the application is as follows: when the wearing size of the chain needs to be adjusted, the through hole 222 of the sliding block 22 slides to coincide with the clamping cavity 211, then the chain body 1 penetrates through the through hole 222 of the sliding block 22, then the wearing size of the chain is adjusted to be comfortable to wear, the sliding block 22 is loosened, the sliding block 22 resets under the driving of the resetting piece 23, the ejector rod 24 penetrates through the chain body 1 to tightly support the chain body 1, and the chain body 1 is not prone to shaking relative to the spring buckle 2.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
