[0002] Currently, a ratchet-type belt tensioner is an industrial fastening device that can quickly tighten and loosen ropes or belts. It has the characteristics of simple structure and easy use. It is widely used in mechanical manufacturing, aerospace, automotive and other fields, especially for fastening items on trucks, trailers, ships or rails, and bundling and fastening steel, wood and various pipes.

[0003] A Chinese utility model patent with announcement number CN207842787U discloses a hand-cranked tape tensioner. Although the above-mentioned prior art is convenient for bundling goods, has an attractive appearance, and is easy to use, the tensioner requires a matching tape when in use. If the tape is not matched, it cannot be used normally and the tensioner and the tape may be damaged. The tape is separate from the tensioner. When the equipment is needed, it is necessary not only to find the matching tape but also to install the loose tape on the tensioner. This is time-consuming and affects the efficiency of the equipment. Therefore, it is necessary to design a ratchet-type tape tensioner that can reel the matching tape onto the tensioner. Utility Model Content

[0004] In order to solve the technical problem that a winding belt cannot be directly installed on a winder for carrying, the utility model provides a ratchet type winding belt tensioner.

[0005] The utility model is implemented by the following technical solutions: a ratchet-type belt tensioner, including a tensioner, a belt mounted on the tensioner, a winding assembly capable of winding up the loose belt, both sides of the winding assembly are provided with fixing assemblies for fixing the belt after it is wound up to prevent it from spreading, the winding assembly includes a winding box arranged on one side of the tensioner and a winding roller arranged inside the winding box, a winding opening is opened on one side of the winding roller, and one end of the belt extends to the inside of the winding box and passes through the winding opening.

[0006] Through the above technical solution, when the tensioner is not in use, one end of the tape is inserted into the winding roller, and the fixing component can be used in conjunction with the winding component to wind the tape into the winding component, so that the tape can be carried together with the matching tensioner.

[0007] As a further improvement of the above solution, the fixing assembly includes a ratchet rotatably mounted on one side of the tensioner, a rotating column mounted on one side of the tensioner and provided with a torsion spring therein, and a clamping block mounted on one side of the rotating column.

[0008] Through the above technical solution, the ratchet and the clamping block can fix the wound tape to prevent the tape from loosening.

[0009] As a further improvement of the above solution, both ends of the winding roller pass through the winding box and are fixedly mounted to adjacent ratchets, and each of the clamping blocks is adapted to the adjacent ratchets.

[0010] Through the above technical solution, the clamping block can fix the ratchet, thereby fixing the belt.

[0011] As a further improvement of the above solution, a twisting column is fixedly installed on one side of each ratchet, and a friction groove is provided on the circumferential surface of each twisting column.

[0012] With the above technical solution, the ratchet wheel and the winding roller can be rotated together by manually rotating the twisting column.

[0013] As a further improvement of the above solution, fixed plates are fixedly installed on both sides of the top of the winding box, each of the fixed plates is provided with a fixed groove adapted to the tensioner, and a friction plate is fixedly installed on the inner wall of each fixed groove.

[0014] Through the above technical solution, the fixed plate and the friction plate can be directly inserted into the tensioner, so that the tensioner can be used normally without being blocked by the winding box.

[0015] As a further improvement of the above solution, limiting plates with sliding grooves are fixedly installed on both sides of the winding box, and a cover plate that slides with the two limiting plates is provided on the top of the winding box.

[0016] Through the above technical solution, the cover plate can prevent foreign objects from entering the reel box and affecting the tape.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] The utility model provides a winding assembly and a fixing assembly. When the tensioner is not in use, one end of the tape adapted for the tensioner is inserted into the winding assembly. The loose tape can be rolled into the winding box during the rotation of the winding assembly. The fixing assembly also fixes the winding assembly so that the wound tape will not become loose, allowing the adapted tape to be carried together with the tensioner, and the winding assembly can be disassembled when not in use to prevent the winding assembly from affecting the use of the tensioner. In this way, the adapted tape can be carried together and the use of the tensioner can be prevented from being affected. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Below, the present invention is further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0025] Please combine Figure 1-Figure 3 The present embodiment is a ratchet-type tape tensioner, comprising a tensioner 1, a tape 2 being mounted on the tensioner 1, a winding assembly being provided on one side of the tensioner 1 for winding up the loose tape 2, and fixing assemblies being provided on both sides of the winding assembly for fixing the tape 2 after it is wound up to prevent it from spreading out, the winding assembly comprising a winding box 301 arranged on one side of the tensioner 1 and a winding roller 302 arranged inside the winding box 301, a winding opening being provided on one side of the winding roller 302, one end of the tape 2 extending into the interior of the winding box 301 and passing through the winding opening, when the tensioner 1 is not in use, one end of the tape 2 is inserted into the winding roller 302, and the fixing assembly can be used in conjunction with the winding assembly to wind the tape 2 into the winding assembly, so that the tape 2 can be carried together with the matching tensioner 1.

[0026] Combine Figure 1-Figure 3 The fixing component includes a ratchet 401 rotatably installed on one side of the tensioner 1, a rotating column 402 installed on one side of the tensioner 1 and provided with a torsion spring inside, and a clamping block 403 installed on one side of the rotating column 402. Both ends of the winding roller 302 pass through the winding box 301 and are fixedly installed with adjacent ratchets 401. Each clamping block 403 is adapted to the adjacent ratchet 401. A twisting column 5 is fixedly installed on one side of each ratchet 401. A friction groove is provided on the circumferential surface of each twisting column 5. The clamping block 403 can fix the ratchet 401, thereby fixing the belt 2.

[0027] Combine Figure 1 and Figure 3, fixed plates 6 are fixedly installed on both sides of the top of the winding box 301, each fixed plate 6 is provided with a fixing groove adapted to the tensioner 1, and a friction plate 7 is fixedly installed on the inner wall of each fixing groove, and limiting plates 8 with sliding grooves are fixedly installed on both sides of the winding box 301. A cover plate 9 is provided on the top of the winding box 301 that slides with the two limiting plates 8. The fixed plate 6 and the friction plate 7 can be directly inserted into the tensioner 1, so that the tensioner 1 can avoid being blocked by the winding box 301 during normal use.

[0028] The implementation principle of a ratchet-type belt tensioner in the embodiment of the present application is as follows: when the tensioner 1 is not in use, the winding box 301 cooperates with the two fixing plates 6 to be inserted on the tensioner 1, and then one end of the belt 2 is inserted into the interior of the winding box 301, and one end is inserted into the winding opening of the winding roller 302, and then the twisting column 5 is rotated to rotate the winding roller 302, so that the belt 2 is rolled up by the winding roller 302, and the clamping block 403 cooperates with the ratchet 401 to allow the winding roller 302 to be wound. It is fixed and cannot be rotated in the reverse direction to loosen the tape 2. Only by moving the block 403 can the winding roller 302 be rotated in the reverse direction, so that the tape 2 can be wound and fixed. Finally, the cover plate 9 is inserted into the sliding groove of the limit plate 8 to prevent foreign objects from entering the winding box 301. When the tape 2 is needed, it is only necessary to take the tape 2 out of the winding box 301 and take down the winding box 301. This allows the adapted tape 2 to be portable together and prevents the use of the tensioner 1 from being affected.

[0029] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
