DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0022] Embodiment 1: please refer to Figures 1-5 A kind of safety shoes convenient to wear, including shoe body 1, the periphery of shoe body 1 is provided with tightening belt 3, the both ends of tightening belt 3 are connected with pull ring 32 and pull rope 31 respectively, pull rope 31 is connected with spiral spring 43, spiral spring 43 is connected with rotating shaft 41, rotating shaft 41 is rotatably installed in adjusting part 2, adjusting part 2 is connected with pull ring 32 by hook 21, adjusting part 2 is fixedly installed with adjusting frame 8, the notch in the top of adjusting frame 8 is slidably installed with push plate 82, push plate 82 is provided with anti-skid pattern 81, the bottom of push plate 82 is fixedly connected with connecting rod 85, connecting rod 85 is slidably installed in slide 83, connecting rod 85 is connected with one end of slide 83 by spring one 84, connecting rod 85 is fixedly installed in the top of moving frame 7, moving frame 7 is connected with limiting rod 61 by sliding rod 63.

[0023] Moving frame 7 is arranged below adjusting frame 8, the inside of moving frame 7 is provided with sliding groove one 71, sliding groove one 71 is horizontally arranged, sliding rod 63 is slidably installed in sliding groove one 71.

[0024] Specifically, when the spring 84 is in a normal state, the limiting rod 61 can enter a closed state, and when it is necessary to keep the limiting rod 61 in an open state, the push plate 82 is pushed to slide in the notch of the adjusting frame 8, and since the connecting rod 85 at the bottom of the push plate 82 is fixedly connected to the top of the moving frame 7, the movement of the push plate 82 will be directly transmitted to the moving frame 7. The moving frame 7 is internally provided with a horizontal sliding groove 71, and when the moving frame 7 moves, the sliding rod 63 is driven to move through the sliding groove 71, so as to control the limiting rod 61 to rotate around the fixed rod 6 and open through the sliding rod 63. In this process, the connecting rod 85 moves in the sliding groove 83, and the spring 84 is compressed;

[0025] In a normal state, the push plate 82 is installed in the notch provided at the top of the adjusting frame 8, and the notch plays a role of physically isolating and position-limiting the push plate 82. This embedded design makes the push plate 82 have a reduced exposed part, which will not be easily touched by external objects, reducing the possibility of triggering due to accidental collision in a normal state. At the same time, the spring 84 is connected to the connecting rod 85 at the bottom of the push plate 82 and one end of the sliding groove 83. The presence of the spring 84 increases the difficulty of triggering the push plate 82. Only when the force applied to the push plate 82 is enough to overcome the elastic force of the spring 84, the push plate 82 will produce enough displacement to trigger the corresponding function. When an accidental external force is applied to the push plate 82, the spring 84 will generate resistance to the external force. Some accidental small collisions or slight contact forces are usually not enough to overcome the elastic force of the spring 84. In this way, accidental touching of the push plate 82 due to these small, unintended external forces is effectively avoided, ensuring that the safety shoe tightening device will only be started when it is really necessary to adjust, thereby guaranteeing the protection function of the safety shoes.

[0026] In example 2, to realize the tightening work of the tightening belt 3, please refer to Figures 1-5 On the basis of example 1, one end of the limiting rod 61 is rotatably installed on the fixed rod 6, the fixed rod 6 is fixedly installed on one side of the partition plate 22, the other end of the limiting rod 61 is located in the tooth groove of the ratchet wheel 42, the ratchet wheel 42 is fixedly installed on the rotating shaft 41, and the limiting rod 61 is provided with a sliding groove 62, and the sliding rod 63 is slidably arranged in the sliding groove 62.

[0027] The side of the limiting rod 61 away from the moving frame 7 is connected with a spring 51, the limiting rod 61 is connected with the fixed block 5 through the spring 51, the fixed block 5 is fixed on the partition plate 22, and the spring constant of the spring 84 is greater than that of the spring 51.

[0028] The other side of the partition plate 22 is connected with a rotating groove 23, one end of the rotating shaft 41 provided with a helical spring 43 is rotatably arranged in the rotating groove 23, and the other end of the rotating shaft 41 is fixedly connected with the handle 4.

[0029] Specifically, in the initial state, the tightening belt 3 is relatively relaxed. The helical spring 43 is in a natural state. After the user puts on the safety shoes, the user rotates the handle 4. The handle 4 drives the rotating shaft 41 to rotate, and the rotation of the rotating shaft 41 causes the helical spring 43 to be contracted. Since the pull rope 31 is connected with the helical spring 43, the pull rope 31 moves with the deformation of the helical spring 43. The movement of the pull rope 31 causes the two ends of the tightening belt 3 to be pulled close, so as to realize the tightening of the tightening belt 3 around the side of the shoe body 1;

[0030] The spring one 84 and the spring two 51 are both in a normal state, and one end of the limiting rod 61 is located in the tooth groove of the ratchet wheel 42. In the process of rotating the rotating shaft 41, the ratchet wheel 42 also rotates. In this process, the tooth block of the ratchet wheel 42 constantly pushes the limiting rod 61 to rotate around the fixed rod 6. At this time, the spring two 51 is stretched. When the limiting rod 61 corresponds to the other side tooth groove, the spring two 51 loses the restriction of the tooth block and returns to the original state, drives the limiting rod 61 into the corresponding tooth groove, and further prevents the reverse rotation of the ratchet wheel 42 and the rotating shaft 41, thereby fixing the tightening state of the tightening belt 3 and completing the protection work.

[0031] Working principle: initially, the tightening belt 3 is in a relaxed state, and the helical spring 43 is in a natural state. After the user puts on the safety shoes, the user rotates the handle 4, drives the rotating shaft 41 to rotate through the handle 4, and makes the helical spring 43 contract. The pull rope 31 connected with the helical spring 43 moves and pulls the two ends of the tightening belt 3 close to each other, so as to realize the gradual tightening of the tightening belt 3 around the side of the shoe body 1. In this process, the ratchet wheel 42 rotates with the rotating shaft 41, and the tooth block of the ratchet wheel 42 pushes the limiting rod 61 to rotate around the fixed rod 6, so that the spring two 51 is stretched. When the limiting rod 61 corresponds to the other side tooth groove of the ratchet wheel 42, the spring two 51 returns to the original state due to the loss of the tooth block restriction, drives the limiting rod 61 into the corresponding tooth groove, and prevents the reverse rotation of the ratchet wheel 42 and the rotating shaft 41. Through the continuous rotation of the ratchet wheel 42, the tightening state of the tightening belt 3 is fixed, and the wearing protection work of the safety shoes is completed.

[0032] When the safety shoes need to be taken off, the limiting rod 61 needs to be kept in an open state, and the push plate 82 needs to be pushed to slide in the notch of the adjusting frame 8. Because the connecting rod 85 at the bottom of the push plate 82 is fixedly connected with the top of the moving frame 7, the movement of the push plate 82 will be transmitted to the moving frame 7. The moving frame 7 drives the sliding rod 63 to move through the internal horizontal sliding groove one 71. The sliding rod 63 moves in the sliding groove two 62 while controlling the limiting rod 61 to rotate around the fixed rod 6 and open. Then, the helical spring 43 reversely rotates the rotating shaft 41 due to the loss of the limiting of the limiting rod 61, and makes the pull rope 31 relax, so that the tightening belt 3 is loose, and the safety shoes can be pulled off.
