Description

A winding shaft with anti-slip function Technical Field

[0001] This utility model relates to the field of winding shaft technology, specifically a winding shaft with anti-slip function. Background Technology

[0002] Chinese patent publication number "CN 109775470 A" discloses a "thin-walled impact-resistant cement rod" including a winding shaft with protruding fixing teeth on its surface and fixing plates at both ends. This invention discloses a winding shaft with a fixing function, featuring fixing teeth on its surface and fixing plates at both ends, which can fix the wound object and improve winding efficiency. However, this patent's fixing teeth on the winding shaft surface can damage the wound object, and the contact area between the wound object and the fixing teeth will protrude, leading to a reduction in winding quality. Furthermore, this patent's winding shaft requires manual assistance during winding, which can easily cause hands to become entangled, resulting in low safety. Therefore, we propose a winding shaft with an anti-slip function. Summary of the Invention

[0003] The purpose of this utility model is to provide a winding shaft with anti-slip function to solve the problems mentioned in the background art, such as damage to the winding material when the fixing teeth fix it, and the bulge at the contact point between the winding material and the fixing teeth, which leads to a reduction in winding quality. In addition, the winding shaft of this patent requires manual assistance during winding, which can easily entangle the hands and reduce safety.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a winding shaft with anti-slip function, comprising a shaft body, a limiting disk fixedly connected to the front and rear side walls of the shaft body, a hidden groove formed around the outer side of the shaft body, the hidden groove being evenly distributed in a ring, a through hole formed in the inner cavity of the hidden groove, a connecting post inserted into the inner cavity of the through hole, a support plate embedded in the inner cavity of the hidden groove, one end of the connecting post being fixedly connected to the inner side wall of the support plate, and an outer wedge block being fixedly connected to the other end of the connecting post, a first return spring provided on the inner side of the outer wedge block, an installation cylinder fixedly connected between the middle of the front and rear side walls of the inner cavity of the shaft body, a movable through groove formed around the outer side wall of the installation cylinder, the movable through groove being evenly distributed in a ring, a movable post slidably connected to the inner cavity of the installation cylinder, an inner wedge block being fixedly connected around the outer side wall of the movable post, the inner wedge block being located in the inner cavity of the movable through groove, and the inclined surface of the inner wedge block contacting the outer wedge block.

[0005] Preferably, the front sidewall of the movable column has a screw hole, and a rotating bolt is screwed into the inner cavity of the screw hole. The front end of the rotating bolt passes through the mounting cylinder, the shaft and the limiting plate and extends to the front side of the limiting plate. The rotating bolt is rotatably connected to the mounting cylinder, the shaft and the limiting plate.

[0006] Preferably, a mounting bracket is fixedly connected to the top of the inner cavity of the shaft, a movable plate is slidably connected to the bottom of the inner cavity of the mounting bracket, a movable wedge is fixedly connected to the top of the movable plate, and the movable wedges are arranged sequentially from front to back. A movable bolt is rotatably connected to the rear side wall of the mounting bracket, and the rear end of the movable bolt passes through the shaft and the limiting plate and extends to the front side wall of the limiting plate. The movable bolt is screwed to the shaft and the limiting plate.

[0007] Preferably, the top of the movable plate is provided with a top block, and the bottom of the top block is fixedly connected with a bottom wedge block. The bottom wedge blocks are arranged sequentially from front to back, and the bottom wedge blocks are in contact with the inclined surface of the movable wedge block.

[0008] Preferably, the top of the shaft has a V-shaped through groove, and the left and right side walls of the inner cavity of the V-shaped through groove have limiting grooves, which are arranged sequentially from front to back.

[0009] Preferably, clamping plates are placed on the left and right sides of the inner cavity of the V-shaped through groove. Limiting blocks are fixedly connected to the outer wall of the clamping plates, and the limiting blocks are arranged sequentially from front to back. The limiting blocks are slidably connected to the inner cavity of the limiting groove. A second return spring is fixedly connected to the bottom of the clamping plate, and the second return spring is arranged sequentially from front to back. The bottom end of the second return spring is fixedly connected to the bottom of the inner cavity of the mounting bracket. An inclined surface is opened on the lower side of the inner wall of the clamping plate, and the bottom of the top block is embedded between the inclined surface on the lower side of the inner wall of the clamping plate.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This anti-slip winding shaft moves by screwing a rotating bolt into a screw hole. The moving column moves accordingly within the mounting cylinder, simultaneously moving the inner wedge block. The inner wedge block presses against the outer wedge block and is limited by a moving through groove. The outer wedge block moves the support plate via a connecting column, causing the outer side of the support plate to protrude from the shaft body, thus fixing the wound material. This ensures that the wound material is fixed without causing damage, improving the winding quality.

[0012] This anti-slip winding shaft rotates by turning the moving bolt, which in turn moves the moving plate. The moving plate simultaneously moves the moving wedge to compress the bottom wedge block, which in turn moves the top block upward. At the same time, the top block pushes against the two clamping plates in the V-shaped through groove. The clamping plates separate under the action of the limiting block and the limiting groove, placing one end of the winding material between the clamping plates. By rotating the moving bolt in the opposite direction, the clamping plates move downward under the action of the second return spring to clamp the winding material before winding. This design prevents workers from getting their hands tangled during operation, thus improving the safety of winding. Attached Figure Description

By turning the rotating bolt 135, the screw is moved in the screw hole 134. The moving column 132 moves in the mounting cylinder 130, and at the same time, it drives the inner wedge block 133 to move. The inner wedge block 133 presses the outer wedge block 120 and is limited by the moving through groove 131. The outer wedge block 120 drives the support plate 113 to move through the connecting column 112, so that the outer side of the support plate 113 protrudes from the shaft 100 to fix the wound material.

[0024] In summary, this method can fix the wound material without damaging it, thus improving the quality of the winding.

[0025] Please refer to Figures 1, 3, and 5. A mounting bracket 140 is fixedly connected to the top of the inner cavity of the shaft 100. A movable plate 141 is slidably connected to the bottom of the inner cavity of the mounting bracket 140. Movable wedges 142 are fixedly connected to the top of the movable plate 141, and the movable wedges 142 are arranged sequentially from front to back.

The movable bolt 143 is screwed onto the shaft 100 and the limiting plate 101. Next, a top block 150 is provided on the top of the movable plate 141, and a bottom wedge block 151 is fixedly connected to the bottom of the top block 150. The bottom wedge blocks 151 are arranged sequentially from front to back and are in contact with the inclined surface of the movable wedge block 142.
