Description

Technical Field

[0001] The utility model relates to a cable tightener, in particular to a cable tightener which is easy to operate and belongs to the technical field of cable installation tools. Background Art

[0002] In the prior art, the utility model with application number 202322964874.6 discloses a cable tensioner for cable installation. In order to solve the problem that the length of the tensioning handle of the traditional tensioner is fixed, when the tensioning position is far away from the operator or there are many beams on the fixed frame, it will cause the tensioning operation to be more difficult. If the operator forces the operation, it is easy to step on air, which is a very dangerous problem. The length of the tensioning handle is adjusted. When the operator is far away from the tensioning position, the telescopic rod can be pulled outward to increase the length of the tensioning handle, so that the operator can perform the tensioning operation at a farther position. This not only facilitates the operator's tensioning operation, but also eliminates the need for the operator to risk going to a closer distance to operate, avoids the operator's forced operation and stepping on air, reduces the danger of the tensioning operation, and ensures the safety of the operator.

[0003] Similar to the above application, there are still some deficiencies:

[0004] Although the length of the handle can be adjusted during use, since the handle is fixed to one side of the tensioner, the operator can only operate conveniently on the side close to the handle during adjustment, so the operator needs to change his position, which is inconvenient to operate.

[0005] Therefore, a convenient-to-operate cable tightener is designed to optimize the above problems. Utility Model Content

[0006] The main purpose of the present invention is to provide a cable tensioner which is easy to operate. Slots are provided at both ends of the line roller, and an insert block is fixed at the end of the handle. The insert block and the slot are plugged into each other, and a positioning mechanism composed of a positioning bead, a positioning groove, a limit groove, a slide groove, an insert rod, an annular groove, a return spring, and a pull ring is used. During use, the position of the handle can be adapted according to the use requirements, so that the operator can operate on different sides of the frame, which is more practical. By arranging strip grooves, balls and extension rods on the handle, the length of the handle can be changed during use. In addition, the traditional reciprocating swinging handle for winding can be changed. By placing the extension rod perpendicular to the outer edge of the handle, the handle can be controlled to rotate by holding the extension rod, which speeds up the winding rate and is more convenient to use.

DETAILED DESCRIPTION

[0023] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is described in further detail below with reference to embodiments and drawings, but the implementation manner of the present invention is not limited thereto.

[0024] like Figures 1-4 As shown, this embodiment provides a cable tensioner that is easy to operate, including a frame 1, a fixed hook 5 installed on the top of the frame 1, a wire roller 2 rotatably installed in the middle position of the frame 1, a cable wound around the wire roller 2, a traction hook 6 fixed on the end of the cable, a ratchet 3 installed at both ends of the wire roller 2 and a ratchet 4 cooperating with the ratchet 3, slots 9 are provided at both ends of the wire roller 2, an insert block 8 is installed inside the slot 9, a handle 7 is installed at the end of the insert block 8, and a limiting mechanism for positioning the insert block 8 is provided inside the insert block 8.

[0025] The overall working principle: when in use, hang the fixed hook 5 on a fixed object, then connect the traction hook 6 to the cable, and then change the position of the handle 7 according to the position of the operator, take the handle 7 to the same side as the operator, and insert the plug 8 on the handle 7 into the inside of the slot 9, and then use the limiting mechanism to fix the position of the plug 8, and then use the handle 7 to drive the rotation of the line roller 2, and use the ratchet 4 to block the reverse movement of the ratchet wheel 3 to automatically position the position of the line roller 2.

[0026] In this embodiment, the limiting mechanism includes a positioning bead 13, a positioning groove 14 and a limiting groove 15. The plug block 8 is in the shape of a quadrangular prism. The outer side of the plug block 8 is provided with a limiting groove 15. The interior of the limiting groove 15 is slidably installed with a positioning bead 13. The interior of the plug block 8 is provided with an extension component for controlling the sliding of the positioning bead 13, and the inner side of the slot 9 is provided with a positioning groove 14 that cooperates with the positioning bead 13.

[0027] Local working principle: After the plug 8 is inserted into the slot 9, the positioning bead 13 inside the limit groove 15 is pushed outward through the expansion component, and the positioning bead 13 partially extends to the outside of the limit groove 15 and enters the inside of the positioning groove 14, thereby fixing the position of the plug 8.

[0028] In this embodiment, the extension component includes a slide 16, an insertion rod 17, a return spring 18 and an annular groove 19. The slide 16 is opened at the end of the handle 7 and the inside of the insert block 8. The insertion rod 17 is slidably installed inside the slide 16. A return spring 18 is provided between the insertion rod 17 and the inner end of the slide 16. An annular groove 19 is opened at the end of the insertion rod 17 close to the return spring 18.

[0029] Partial working principle: When inserting the plug-in block 8, pull the plug rod 17 outward. At this time, the outer side of the annular groove 19 is aligned with the positioning bead 13. During the insertion process, the positioning bead 13 can be squeezed into the inside of the plug-in block 8. After the plug-in block 8 is inserted, release the plug rod 17. The reset spring 18 controls the reset of the plug rod 17. The outer side of the plug rod 17 fits with the outer side of the positioning bead 13, and the positioning bead 13 is squeezed out.

[0030] In this embodiment, a pull ring 20 is fixed to one end of the insertion rod 17 away from the return spring 18 , and the inner diameter of the pull ring 20 is 2 cm.

[0031] Partial working principle: During use, a finger can pass through the inside of the pull ring 20 to facilitate the control of pulling the insertion rod 17.

[0032] In this embodiment, an opening is provided at the end of the wire roller 2 and is located outside the slot 9 , and an inclined surface is formed between the opening and the end of the slot 9 .

[0033] Partial working principle: The opening can guide the plug-in block 8 when it is inserted into the slot 9, making it easier to insert.

[0034] In this embodiment, a strip groove 10 is formed on one end of the side of the handle 7 away from the inserting block 8 , and an extension rod 12 is movably mounted on the inner end of the strip groove 10 .

[0035] Partial working principle: During use, the extension rod 12 can be pulled out from the inside of the strip groove 10. When the extension rod 12 is in a straight line with the handle 7, the length of the handle 7 is increased, which is more practical and labor-saving.

[0036] In this embodiment, the end of the strip groove 10 extends to the end of the handle 7, and the end of the strip groove 10 is connected to both sides of the handle 7. A ball 11 is rotatably installed on one end of the plug block 8 inside the strip groove 10, and the extension rod 12 is fixed on the ball 11.

[0037] Partial working principle: Since the ends of the strip groove 10 are connected to both sides of the handle 7, the rotation of the ball 11 can be controlled by rotating the extension rod 12 to the outside of the handle 7 vertically, and the rotation of the handle 7 can be controlled by hand cranking, which is more practical.

[0038] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and concept of the present invention within the scope disclosed by the present invention, which falls within the protection scope of the present invention.
