Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. example. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

1-4, the present utility model provides a technical solution: a locking mechanism for gymnastics equipment, comprising a fixing sleeve 13, a plurality of hinge seats 9 are fixedly connected on the circumference of the fixing sleeve 13 at equal distances, and a plurality of hinge seats 9 is hinged with a hinge rod 1, the fixed sleeve 13 is provided with an external thread 2, the external thread 2 is threadedly connected with a threaded sleeve 12, and the outer wall of the threaded sleeve 12 is fixedly connected with a movable seat 3, and the surface of the movable seat 3 is inclined. , the fixed sleeve 13 is fixed on the lower end tubular object by welding, and the position of the threaded sleeve 12 on the external thread 2 is adjusted by rotating the threaded sleeve 12. When the movable seat 3 moves upward, the movable seat 3 will form a formation on the hinge rod 1. Thrust, the hinge rod 1 will rotate with the hinge seat 9 as the center of the circle, so that the other end of the hinge rod 1 is abutted with the upper end of the tube for fixing, and the distance from the upper end of the hinge rod 1 to the hinge seat 9 is smaller than the lower end of the hinge rod 1 From the distance to the hinged seat 9, the hinged rod 1 acts as a labor-saving lever, amplifying the force, so that a small force can be used to drive the threaded sleeve 12 to rotate, so that the movable seat 3 moves, which is beneficial to the operation. Convenience, when the moving base 3 moves downward, there is no push force on the hinge rod 1, the hinge rod 1 will release the fixation of the tubular object, adjust the distance between the upper tubular object and the lower tubular object, and adjust the height of the instrument.

A grip rod 4 is fixedly connected to the threaded sleeve 12 , and by adopting the design of the grip rod 4 , the grip rod 4 is grasped so as to drive the threaded sleeve 12 to rotate.

Among them, since the instrument will vibrate during use, and when tightening, the threaded connection is used, and the vibration will cause the threaded connection to loosen. The threaded sleeve 12 is provided with a tightening mechanism. The tightening mechanism includes the connection The plate 5, the spring 7, the fastening plate 8, the connecting edge 11, the fastening plate 8 is an arc-shaped plate, the inner annular wall of the fastening plate 8 is fitted with the fixing sleeve 13, and the connecting plate 5 is fixedly connected to the grip rod 4, The connecting plate 5 is provided with a rectangular groove, a connecting edge 11 can be inserted into the rectangular groove, one end of the connecting edge 11 is fixedly connected with a fastening plate 8, the fastening plate 8 is in contact with the fixing sleeve 13, and the spring 7 is sleeved on the connecting edge. 11, one end of the spring 7 is fixedly connected to the connecting plate 5, and the other end is fixedly connected to the fastening plate 8. The spring 7 is in a compressed state. The 8 pairs of fixed sleeves 13 abut against each other, which increases the frictional force when the fastening plate 8 rotates, so as to limit the position of the threaded sleeve 12 and prevent the threaded sleeve 12 from rotating, thereby preventing the effect of locking due to vibration. .
