Technical Field

[0001] The utility model relates to the technical field of binding belts, in particular to a ratchet type automatic binding belt. Background Art

[0002] A binding belt is a strip-shaped object, which is widely used for binding, fixing or supporting items. It can be used in the medical field, such as fixing wounds or supporting joints, and also in fashion design such as shoelaces and clothing decoration, and in daily life for binding packages and organizing items. According to the use, the material of the binding belt can be cloth, rubber, plastic or leather.

[0003] However, in actual use, there are still the following deficiencies. For example, manual labor cannot achieve a 24-hour non-stop working mode. Due to the physiological limitations of humans, long-term labor will lead to the accumulation of fatigue. In some operations that require high precision and repetition, such as tightening and loosening the binding belt, since manual operation depends on the reaction speed and concentration of a person, these factors will gradually decline after long-term work, resulting in a slowdown in the operation speed and even mistakes.

[0004] Therefore, the utility model provides a ratchet type automatic binding belt. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the defects existing in the prior art and provide a ratchet type automatic binding belt.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme: a ratchet type automatic binding belt, including a binding belt, a tensioning component is arranged on the outer side of the binding belt, a positioning component is slidably connected inside the tensioning component, and an adjusting component is fixedly connected to the outer side of the tensioning component;

[0007] The tensioning component includes a binding head seat, and the inside of the binding head seat is slidably connected to the outer side of the binding belt;

[0008] The adjusting component includes a positioning bolt, one end of the positioning bolt is fixedly connected to the binding head seat, an adjusting bolt is slidably connected to one end of the outer side of the binding head seat close to the positioning bolt, a spring is fixedly connected to the outer side of the positioning bolt, and a force-releasing piece is rotatably connected to the outer side of the adjusting bolt.

When in use, the belt is passed through the holes of the binding head seat and the rotating shaft, and then connected to the hexagonal hole on the rotating shaft. The rotating shaft is rotated to wind the belt around the rotating shaft to tighten. Due to the action of the spring, the limiting ratchet wheel and the ratchet teeth are always meshed to ensure that the belt can only rotate in one direction to achieve self-locking. If it is necessary to loosen, the internal mechanism will trigger the unloading piece to stretch the spring, and the ratchet teeth will be separated from the limiting ratchet wheel and no longer meshed. At this time, reverse the rotating shaft and lift the binding head to loosen the belt. Such a design can achieve the effect that the binding belt can automatically tighten during the tightening process, ensure that the binding belt can operate in an appropriate tension state, effectively solve the problem that manual operation cannot work efficiently for a long time, realize a reliable self-locking function, and avoid the loosening problem that may occur in manual operation.

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0030] As Figure 1 - Figure 3 shown, this embodiment provides a technical solution: a ratchet - type automatic strap, including a binding strap 1. A tensioning assembly 2 is arranged on the outer side of the binding strap 1. A positioning assembly 3 is slidably connected inside the tensioning assembly 2. An adjusting assembly 4 is fixedly connected to the outer side of the tensioning assembly 2;

[0031] The tensioning assembly 2 includes a strap head seat 21, the interior of the strap head seat 21 is slidably connected to the outer side of the binding belt 1, the inner wall of the strap head seat 21 is rotatably connected with a rotating shaft 22, the outer side of the binding belt 1 is slidably connected to the inside of the rotating shaft 22, the outer side of the rotating shaft 22 is fixedly connected to a limited ratchet 23, one end of the rotating shaft 22 close to the limited ratchet 23 is threadedly connected with a nut 24, the interior of the adjusting bolt 42 is rotatably connected with a ratchet 25, the limited ratchet 23 is meshed with the ratchet 25, and the inner end of the ratchet 25 away from the adjusting bolt 42 is rotatably connected with a positioning column 26. The binding belt 1, as the main body in the overall structure, is made of a woven belt and has the characteristics of high strength and good flexibility. The function of the binding belt 1 is to achieve the fixation of the article and to tighten or relax it with the operation of other components. The design of the strap head seat 21 enables it to be slidably connected to The outer side of the binding belt 1 is connected by sliding, so that the binding belt 1 can cooperate with the movement of other components more flexibly. The inner wall of the binding head seat 21 is rotatably connected with the rotating shaft 22. This design enables the binding belt 1 to be adjusted smoothly during rotation to prevent jamming during operation. The rotating shaft 22 realizes precise control of the binding belt 1 with the help of the limiting ratchet 23. The function of the limiting ratchet 23 is to prevent the binding belt 1 from loosening in the reverse direction. Once the binding belt 1 is tightened, it will be engaged with the ratchet 25 to ensure that the binding belt is in a tightened state. The cooperation between the nut 24 and the limiting ratchet 23 provides a locking force to ensure that the limiting ratchet 23 can be fixed in the specified position. The design of the ratchet 25 enables it to mesh with the limiting ratchet 23 to provide a unidirectional tightening effect. When the binding belt 1 is tightened, the engagement of the ratchet and the limiting ratchet 23 can effectively prevent it from loosening back.

[0032] The adjusting assembly 4 includes a positioning bolt 41, one end of which is fixedly connected to the strap head seat 21, and an adjusting bolt 42 is slidably connected to the end of the strap head seat 21 close to the positioning bolt 41. A spring 43 is fixed to the outer side of the positioning bolt 41, and the end of the spring 43 away from the fixed shaft 31 is fixedly connected to the adjusting bolt 42. The outer side of the adjusting bolt 42 is rotatably connected to a force unloading piece 44. The adjusting bolt 42 enables the user to accurately adjust the tension of the binding strap 1, and cooperates with the resilience of the spring 43 to maintain an appropriate tension state. When the tension needs to be released, the design of the force unloading piece 44 can release the fastening state of the binding strap 1 through simple operation, so that the items can be easily taken out or adjusted, and under the elastic force of the spring 43, the ratchet 25 and the limit ratchet 23 are always engaged, and the head of the binding strap 1 can only rotate in one direction to achieve a self-locking effect;

[0033] Furthermore, Figure 1 - Figure 2As shown: The positioning component 3 includes a fixed shaft 31. The outer side of the fixed shaft 31 is movably connected inside the head seat 21 of the binding strap. A pin 32 is inserted inside the fixed shaft 31. The fixed shaft 31 passes through two round holes at the front end of the binding strap 1, and the tail is fixed with an R-shaped split pin 32.

[0034] Working principle:

[0035] As Figure 1 - Figure 3 shown:

[0036] When in use: The closed-loop end with stitches of the binding strap 1 is sleeved on the fixed shaft 31 of the head of the binding strap for installation. When in use, the other end of the binding strap passes through the middle opening of the head seat 21 of the binding strap and the opening of the rotating shaft. After grasping the head of the binding strap, it is connected to the rotating shaft 22 through the hexagonal hole on the rotating shaft 22. The locking tool rotates the rotating shaft 22 to wind the binding strap around the outer diameter of the rotating shaft 22 in sequence, so as to tighten the binding strap. Under the elastic force of the spring 43, the limiting ratchet 23 and the ratchet teeth 25 are always engaged, and the binding strap 1 can only rotate in one direction, achieving the self-locking effect. When it is necessary to loosen the binding strap, the internal mechanism of the locking tool triggers the force-releasing piece 44. The force-releasing piece 44 rotates around the mounting positioning post 26 of the ratchet teeth 25, supports the connecting bolt of the spring 43 on the ratchet teeth 25, stretches the spring 43, separates the ratchet teeth 25 from the limiting ratchet 23, and no longer engages. By reversing the rotating shaft 22 of the locking tool and lifting the head of the binding strap at the same time, the effect of loosening the binding strap is achieved.

[0037] The above is only the preferred embodiment of the present invention, and it is not a limitation of the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
