Description

Improved structure of bolt

The technical field is as follows:

the utility model relates to an improved structure of bolt.

Background art:

the pin structure in the prior art is more conventional and is difficult to adapt to new use requirements.

The utility model has the following contents:

the utility model aims to solve the technical problem that an improvement structure of bolt that facilitates use is provided.

The technical solution of the utility model is to provide an improved structure of a bolt, which comprises a plate-shaped bolt seat and a movable pin, wherein the movable pin is arranged on the bolt seat in a sliding way, a plurality of fixing holes are arranged on the bolt seat, a first pin ring and a second pin ring are arranged on the bolt seat, the first pin ring is arranged at the front end of the bolt seat, the movable pin is arranged on the first pin ring and the second pin ring in a penetrating way and can rotate around the self axial direction, the movable pin is provided with a head end and a tail end which are opposite in the axial direction, the tail end of the movable pin is bent to form a positioning pin, the tail end of the bolt seat is upwards tilted and provided with a U-shaped notch, a U-shaped positioning seat is arranged on the bolt seat, the movable pin is arranged on the tail end of the bolt seat in a penetrating way in a U-shaped groove of the U-shaped positioning seat, the upper part of the U-, when the locating pin is located between U-shaped locating seat and the bolt seat end, the stiff end of compression spring is located between first cotter ring and the second cotter ring, and the compression spring other end and second cotter ring butt, when the locating pin is located the bolt seat end, the activity round pin is around self axial rotation, and the locating pin is held under the compression spring elastic force and is held in the U-shaped breach at bolt seat end.

Compared with the prior art after the structure more than adopting, the utility model has the advantages of it is following: through this structure, can be under compression spring effect, be in the locking state after making the removable pin and the connecting seat insert, avoid breaking away from naturally, simultaneously, can make the removable pin locking under compression spring effect when removable pin and connecting seat throw off, avoid the removable pin to slide naturally and peg graft with the connecting seat, cause the mistake to lock, simultaneously, can cooperate the lockhole on the U-shaped positioning seat, thereby die at a certain state with padlock cooperation lock, avoid other people to operate.

Preferably, the two sides of the U-shaped positioning seat are provided with lock holes. The two-way installation of two divisions of doors can be realized, and the installation is more convenient.

Description of the drawings:

fig. 1 is a schematic structural diagram of the present invention.

The specific implementation mode is as follows:

the invention will be further explained with reference to the drawings and the detailed description below:

as shown in fig. 1, an improved structure of a bolt comprises a plate-shaped bolt seat 1 and a movable pin 2, wherein the movable pin 2 is slidably disposed on the bolt seat 1, a plurality of fixing holes 3 are disposed on the bolt seat 1, a first pin ring 4 and a second pin ring 5 are disposed on the bolt seat 1, the first pin ring 4 and the second pin ring 5 are fixed on the bolt seat by welding, wherein the first pin ring 4 is disposed at the front end of the bolt seat, the movable pin 2 penetrates through the first pin ring 4 and the second pin ring 5 and can axially rotate around itself, the movable pin 2 has a head end 21 and a tail end which are axially opposite, the tail end of the movable pin 2 is bent to form a positioning pin 23, the tail end of the bolt seat 1 is tilted upward and has a U-shaped notch 6 at the end thereof, a U-shaped positioning seat 7 is further disposed on the bolt seat 1, the U-shaped positioning seat 7 is disposed at the rear end of the bolt seat, the movable pin 2 penetrates through a U-shaped groove of the U-shaped positioning seat, a, the cover is equipped with compression spring 9 on the activity round pin 2, compression spring 9 one end is fixed on the activity round pin through snap ring 10, and it is equipped with the constant head tank to fit with a contraceptive ring at this department activity round pin, the constant head tank sets up along activity round pin circumference, when locating pin 23 is located between U-shaped positioning seat 7 and the bolt seat 1 end, compression spring 9's stiff end is located between first cotter ring 4 and the second cotter ring 5, the compression spring 9 other end and the 5 butt of second cotter ring, at this moment, compression spring is in compression state, in other words, compression spring compresses between snap ring and second cotter ring, when locating pin 23 is located the bolt seat end, activity round pin 2 rotates around self axial, locating pin 23 is held in the terminal U-shaped breach 6 of bolt seat under the effect of compression spring elasticity.

Through this structure, can be under compression spring effect, be in the locking state after making the removable pin and the connecting seat insert, avoid breaking away from naturally, simultaneously, can make the removable pin locking under compression spring effect when removable pin and connecting seat throw off, avoid the removable pin to slide naturally and peg graft with the connecting seat, cause the mistake to lock, simultaneously, can cooperate the lockhole on the U-shaped positioning seat, thereby die at a certain state with padlock cooperation lock, avoid other people to operate.

The foregoing is illustrative of the preferred embodiments of the present invention only, and is not to be construed as limiting the claims. All the equivalent structures or equivalent flow changes made by using the contents of the specification and the attached drawings of the utility model are included in the patent protection scope of the utility model.
