Detailed Description

The following disclosure provides many different embodiments or examples for implementing different features of the invention. To simplify the disclosure of the present invention, the components and arrangements of specific examples are described below. Of course, they are merely examples and are not intended to limit the present invention. Furthermore, the present invention may repeat reference numerals and/or letters in the various examples, such repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed. In addition, the present invention provides examples of various specific processes and materials, but one of ordinary skill in the art may recognize applications of other processes and/or uses of other materials.

Referring to fig. 1-4, a linkage type side lock according to an embodiment of the present invention includes a lock body 1, a push rod 2 and a handle 14. Lock body 1 includes lock seat 3, be provided with push rod connecting block 4 and tapered end 5 in the lock seat 3, push rod connecting block 4 wears to establish in first slide 6 and second slide 7, the internal diameter of first slide 6 is greater than the internal diameter of second slide 7, the cover is equipped with first elastic component 8 on the push rod 2, first elastic component 8 is located first slide 6, tapered end 5 is located third slide 9, second slide 7 and third slide 9 communicate with each other, be provided with second elastic component 10 between tapered end 5 and the third slide 9, spacing groove 11 has been seted up on tapered end 5, push rod connecting block 4 can stretch into in spacing groove 11. The handle 14 assembly is fixedly connected with the push rod connecting block 4 through the push rod 2.

The side lock controls the switch of the lock head 5 through the handle 14, has simple structure, easy manufacture, lower cost and humanized operation.

Specifically, the limiting groove 11 on the lock head 5 has a slope, the push rod connecting block 4 is abutted to the limiting groove 11, and the lock head 5 can make corresponding displacement along with the displacement of the push rod connecting block 4.

Specifically, the lock body 1 is in a rectangular parallelepiped shape. One end of the lock head 5 positioned in the lock body 1 is a flat surface, and the other end is in a bolt shape. The first and second runners 6, 7 are rectangular parallelepiped in shape.

Furthermore, the lock head 5 and the push rod connecting block 4 are both positioned on the side surface of the lock body 1, and the lock head 5 and the push rod connecting block 4 are perpendicular to each other. So, the structure of lock body 1 is comparatively simple, can not occupy too big volume, is convenient for set up in various industrial product.

Further, the handle 14 assembly comprises a fixed seat 13 and a handle 14, and the handle 14 is rotatably arranged in the fixed seat 13. When the handle is not used at ordinary times, the handle 14 is well hidden, and normal use is not influenced. The handle 14 can be easily pulled out when in use.

Further, the fixed seat 13 and the handle 14 are connected through the torsion spring 12 and the T-shaped pin. Therefore, the handle 14 can be stably fixed in the fixing seat 13 and can rotate freely to drive the push rod connecting block 4 to move.

Further, the moving directions of the push rod connecting block 4 and the lock head 5 are perpendicular to each other.

Further, the elastic member is a spring.

In summary, the working principle of the side lock in the invention is as follows:

the handle 14 is pulled, the handle 14 rotates, and the push rod 2 is driven to move towards the direction close to the lock body 1, so that the push rod connecting block 4 is driven to move towards the inside of the lock body 1, at the moment, the first elastic part 8 is compressed, the push rod connecting block 4 moves towards the right to extrude the lock head 5, the second elastic part 10 is stretched, and the lock head 5 is forced to extend out; when the handle 14 is released, the push rod 2 and the push rod connecting block 4 move away from the lock body 1, the first elastic element 8 elastically returns to the original state, the second elastic element 10 is compressed, and the bolt retracts.

While embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that: various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
