The technical realization elements of the new push-pull lock

Technical realization elements:

4. In view of the shortcomings of the prior art, the purpose of the present invention is to provide a new type of push-pull lock.

5. In order to achieve the above purpose, the present utility model provides the following technical solutions:

6. A new type of push-pull lock, comprising a handle seat, the upper end of the handle seat is equipped with a handle, and the lower end is provided with a mounting groove for installing a square shaft sleeve; the handle seat is rotated with a linkage mechanism, the linkage mechanism includes a rotating A linkage member arranged on the handle seat, the upper end of the linkage member is connected with the handle, and the lower end is connected with a push rod for pushing the square shaft sleeve to rotate, wherein the lower end of the push rod passes through the mounting groove and the square shaft sleeve Match

7. The side of the linkage member away from the push rod is installed with a return spring that drives the linkage member to reset;

8. When the handle is pushed, the linkage member rotating on the handle seat drives the push rod to rotate, so that the lower end of the push rod abuts against the square sleeve and pushes the square sleeve to rotate; at the same time, the linkage compresses the return spring downward.

9. The utility model is further provided: the lower end of the handle is provided with a mounting cavity for installing the linkage, one end of the mounting cavity is fixed with a wedge block that matches the linkage, and the side wall at the other end is penetrated with a top Threaded hole

10. When the jack thread is screwed into the threaded hole of the jack thread, the jack thread presses the linkage member so that the linkage member abuts against the wedge-shaped surface of the wedge block.

11. The present utility model is further provided: the lower end of the pushing rod is bent outwards to be provided with a pushing part, wherein the pushing part passes through the installation groove and is matched with the square shaft sleeve.

12. The utility model is further provided: the linkage member is provided with an insertion hole for installing the push rod, wherein the upper end of the push rod is inserted into the insertion hole.

13. The utility model is further provided: the linkage is provided with a first mounting post, and the handle seat is oppositely provided with a second mounting post; wherein the upper end of the return spring is sleeved on the first mounting post, and The lower end part is sleeved on the second mounting post.

14. The present utility model is further provided: an installation assembly for installing a square shaft sleeve is installed in the installation groove, and the installation component includes a mounting seat and a cover plate provided with a rotation hole, wherein the upper end of the square shaft sleeve rotates It is arranged in the rotating hole, and its lower end is pressed on the mounting seat by the cover plate.

15. The utility model is further provided: an escape groove is provided on the mounting seat, and the push rod passes through the escape groove to be matched with the square shaft sleeve.

16. The utility model is further provided: a plurality of fixed posts are arranged in the installation groove, and the installation seat is sleeved on the fixed post.

17. The utility model is further provided: a threaded hole is provided on the fixing column, wherein the fixing screw passes through the cover plate and cooperates with the threaded hole to fix the cover plate on the fixing column.

18. The beneficial effects of the utility model: the handle is linked with the square bushing through the linkage mechanism; when the handle is pushed, the linkage rotating on the handle seat drives the push rod to rotate, so that the lower end of the push rod abuts the square bushing And push the square shaft sleeve to rotate, so that the square shaft inserted in the square shaft sleeve drives the lock tongue to shrink back into the lock body to realize the unlocking of the door lock; the unlocking process can only be done by pressing the end of the handle without hand grip Hold the handle for pressing down operation; the operation is simpler, more convenient and labor-saving; during the unlocking process, the linkage member compresses the return spring downward to store energy for the linkage member to reset; when the handle is released, the linkage member is in the position of the return spring Under the action, the handle is driven to realize the reset.
