A stepped hole with a small outside and a large inside is formed in the shoelace tensioning seat, a lock pin with a small outside and a large inside and arranged in a stepped cylinder shape is sleeved in the stepped hole, the outer end of the lock pin is pressed against the inner wall of the left upper end of the shoelace collecting cavity, and a pressure spring is clamped between the other end of the lock pin and the bottom surface of the stepped hole;

and a pin hole matched with the small end of the lock pin is formed in the outer wall of the right lower end of the base plate.

The outer end of the lock pin is formed with a hemispherical top.

The tensioning wheel is formed with a rope groove, and the shoelace is inserted and sleeved in the rope groove.

The tension wheel is hinged on the base shaft through a bearing.

The middle part of the base shaft is formed with a slot and an insertion hole which are vertically arranged, the inner end of the spring is inserted and sleeved in the slot, a pin shaft is sleeved in the insertion hole, and the pin shaft penetrates through the inner end of the spring.

The lower bottom surface of the base plate is provided with a plurality of through holes in a forming mode, and the lower bottom surface of the base plate is fixed through a plurality of cotton threads between the through holes and the upper.

The invention has the following outstanding effects: compared with the prior art, it can carry out automatic tensioning to the both ends of shoelace through two shoelace tensioners, not only conveniently dresses, has more effectively solved because of the shoelace pine takes off the problem that leads to tumbleing.

Detailed Description

Example, as shown in fig. 1 to 4, a lace-free safety shoe comprises an upper 11 and a lace 12, wherein a lace tensioner 2 is connected to each end of the lace 12;

the shoelace tensioner 2 comprises a base disc 21 fixed on the upper 11, a shoelace collecting cavity 211 is arranged in the base disc 21, a base shaft 22 is fixed in the shoelace collecting cavity 211, the base shaft 22 is fixedly connected with one end of a clockwork spring 23, the other end of the clockwork spring 23 is fixed on the inner wall of a tension wheel 24, a shoelace fastening seat 241 is formed on the outer wall of the tension wheel 24, and one end of the shoelace 12 passes through a gap 214 of the base disc 21 and is fixed on the shoelace fastening seat 241 by winding an extending end of the tension wheel 24.

Furthermore, a stepped hole 242 with a small outer part and a large inner part is formed on the shoelace tensioning seat 241, a lock pin 25 with a small outer part and a large inner part and arranged in a stepped column shape is sleeved in the stepped hole, the outer end of the lock pin 25 is pressed against the inner wall of the upper left end of the shoelace collecting cavity 211, and a pressure spring 26 is clamped between the other end of the lock pin 25 and the bottom surface of the stepped hole 242;

the outer wall of the right lower end of the base plate 21 is formed with a pin hole 212 matched with the small end of the lock pin 25.

Further, the outer end of the locking pin 25 is formed with a hemispherical top 251.

Further, the tension wheel 24 is formed with a rope groove 241, and the shoelace 12 is inserted in the rope groove 241.

Furthermore, the tension wheel 24 is hinged to the base shaft 22 via a bearing 27.

Furthermore, a slot 221 and a jack 222 which are vertically arranged are formed in the middle of the base shaft 22, the inner end of the spiral spring 23 is inserted into the slot 221, a pin 28 is sleeved in the jack 222, and the pin 28 penetrates through the inner end of the spiral spring 23.
