Description

Technical Field

[0001] The utility model mainly relates to the technical field of mechanical tools, and specifically relates to a rope tightener. Background Art

[0002] Ropes are commonly used tools in life, and rope bundling and fixing are often applied in many fields. For example, the fixing of goods transported by water, air, etc. Basically, large goods often need to be fixed and bundled to prevent damage or loss of goods caused by collision, bumping, and vibration during transportation; used in construction site safety protection, etc., using ropes to tighten and fix hoisted goods, fix and support protective structures, etc. If the direct bundling method of ropes is adopted, the ropes are difficult to be tightened, and thus the bundling effect is generally average. Therefore, in order to stably bundle goods, a tightener tool is usually used to tighten the ropes to ensure the bundling effect.

[0003] There are many existing tighteners. The most common ones are threaded barrel tighteners, worm and worm gear structure tighteners, etc. The above-mentioned tighteners have a stable tightening effect, but there is a problem of low use efficiency. There are also some tighteners with complex structures, which can tighten ropes quickly and efficiently, but the complex structural design leads to high production costs and high product prices, making it difficult to popularize and use. Content of the Utility Model

[0004] To solve the deficiencies of the prior art, the utility model provides a rope tightener, which can greatly reduce the production and manufacturing costs of the tightener through delicate structural design, and at the same time can ensure a stable and reliable tightening and fixing effect, which is beneficial to the popularization and use of this product.

[0006] A rope tightener includes a frame for installing various components. The frame includes a rotating seat and a fixed end. The rotating seat is provided with a shaft hole, and the fixed end is provided with a fixed groove. A rotating shaft is movably installed in the shaft hole. The rotating shaft passes through the outside of the rotating seat and is fixedly installed with a one-way gear. A locking device is movably installed on one side of the rotating seat, and tightening nuts are installed at both ends of the rotating shaft.

[0007] The rotating shaft is composed of two semi-circular shaft rods. There is an installation gap between the two semi-circular shaft rods. Connecting pieces are installed at both ends of the installation gap. Fixed holes are opened at both ends of the rotating shaft. Special-shaped fixing rods are installed in the fixed holes. The special-shaped fixing rods pass through the fixed holes and the connecting pieces. One end of the connecting piece close to the rotating seat abuts against the outside of the one-way gear, and a tightening nut is fixedly installed at the outer end of the connecting piece.

[0008] The edge of the semi-circular shaft rod has an arc-shaped edge.

[0009] At least two fixing grooves are provided, and the fixing grooves are arranged parallel to each other.

DETAILED DESCRIPTION

[0019] In conjunction with the accompanying drawings and specific embodiments, the present utility model will be further described. It should be understood that these embodiments are only used to illustrate the present utility model and not to limit the scope of the present utility model. In addition, it should be understood that after reading the content taught by the present utility model, those skilled in the art can make various changes or modifications to the present utility model, and these equivalent forms also fall within the scope defined by this application.

[0020] In conjunction with the attached Figures 1-4 , a rope tensioner, comprising a frame 1 for mounting various components. The frame 1 includes a rotating seat 10 and a fixed end 11. The rotating seat 10 is provided with a shaft hole 100, and the fixed end 11 is provided with a fixed groove 110. A rotating shaft 2 is movably installed in the shaft hole 100. The rotating shaft 2 penetrates through the outside of the rotating seat 10 and is fixedly installed with a one-way gear 3. A locking device 4 is movably installed on one side of the rotating seat 10, and tightening nuts 5 are installed at both ends of the rotating shaft 2.

[0021] The rotating shaft 2 is composed of two semi-circular shaft rods 20. There is an installation gap 21 between the two semi-circular shaft rods 20. Connecting pieces 22 are installed at both ends of the installation gap 21. Fixing holes 23 are provided at both ends of the rotating shaft 2. An irregular fixing rod 24 is installed in the fixing holes 23. The irregular fixing rod 24 penetrates through the fixing holes 23 and the connecting pieces 22. One end of the connecting piece 22 close to the rotating seat 10 abuts against the outside of the one-way gear 3, and a tightening nut 5 is fixedly installed at the outer end of the connecting piece 22.

[0022] The edge of the semi-circular shaft rod 20 has an arc-shaped edge 200; the arc-shaped edge 200 can prevent the installed rope from being worn.

[0023] At least two of the fixed grooves 110 are provided, and the fixed grooves 110 are arranged in parallel.

[0024] Both sides of the fixed end 11 have side plates 111; the side plates 111 can improve the structural strength of the frame 1, and the side plates 111 are relatively low in height, and can be used to fix the frame 1 in some scenarios with relatively narrow spaces.

[0025] The locking device 4 includes a lock piece 40, which is adapted to the one-way gear 3. A positioning hole 101 and a torsion spring hole one 102 are provided on one side of the rotating seat 10. The lock piece 40 is rotatably installed outside the positioning hole 101 through a bolt. A torsion spring 41 is movably installed on the bolt at the rotation installation position of the lock piece 40. A torsion spring hole two 400 is provided on the lock piece 40. A lever 401 is fixedly provided on the lock piece 40. Two force-receiving ends of the torsion spring 41 are respectively inserted into the torsion spring hole one 102 and the torsion spring hole two 400; the torsion force of the torsion spring 41 causes the lock piece 40 to approach the one-way gear 3, and thus the one-way gear 3 is locked when there is no other external force.

[0026] When the device is in use, a bolt is passed through the fixing groove 110 to fix the fixing end 11 of the device in the tightening position. The strip-shaped fixing groove 110 can facilitate accurate adjustment of the installation position. The rope to be tightened is passed through the installation gap 21 of the rotating shaft 2 and then tied and fixed. The tightening nut 5 is rotated with a wrench to tighten the rope. The tightening torque can be accurately determined by using a torque wrench. When it needs to be loosened, the lever 401 is pushed to disengage the one-way gear 3 and the rotating shaft 2 can be freely rotated to loosen the rope.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
