[0004] The above product is easy to use. Based on the above solution, the applicant further optimizes the safety and convenience of use according to actual usage problems. Summary of the invention

[0005] The utility model aims at the above problems existing in the prior art and provides a winch. The technical problem to be solved by the utility model is: how to ensure the safe and convenient use of the winch.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] A winch comprises a bracket and a belt shaft for winding a binding belt, the belt shaft is rotatably connected to the bracket, the bracket comprises a transversely arranged mounting plate, the mounting plate is vertically opposite to the belt shaft, and is characterized in that a reflective identification piece is fixedly provided on the edge of the mounting plate, the reflective identification piece is in a strip shape and is arranged along the side edge of the mounting plate.

[0008] The bracket can be fixed on the carrier, and the belt shaft can rotate relative to the bracket to tighten the binding belt thereon, thereby realizing the tensioning and binding of the binding belt. The bracket is provided with a transversely arranged mounting plate, and the mounting plate can be connected under the bottom plate on the side of the carrier; and reflective marking members in strip shape and arranged along the edge are provided on the edge of the mounting plate, so that the setting position of the reflective marking members will not be too low, and the reflective marking members can produce obvious reflection of light from a more suitable position under low illumination environment at night. At the same time, the strip reflection is helpful for the staff to judge the specific height and position of the winch, and can more easily find and notice the position of the vehicle and the winch at night, so as to operate or avoid them, thereby improving the safety and convenience of use.

[0009] In the above winch, the edge of the mounting plate has a notch groove, and the reflective identification piece is embedded and fixed in the notch groove. In this way, the inner wall of the notch groove is conducive to increasing the contact area between the reflective identification piece and the mounting plate to make the connection stable. At the same time, after being embedded in the notch groove, the reflective identification piece is protected to a certain extent, which can reduce the probability of its collision and damage, and ensure its normal and stable function.

[0010] In the above winch, the edge of the mounting plate has a vertically protruding vertical plate, and the reflective identification piece is fixedly connected to the side of the vertical plate. In this way, the vertical plate has a vertical thickness dimension greater than the thickness of the mounting plate, which is conducive to increasing the arrangement area of ​​the reflective identification piece, making it easier for the staff to find the position of the winch for operation or avoidance.

[0011] In the above winch, the reflective identification member is a reflective coating sprayed on the mounting plate or a reflective strip pasted on the mounting plate. The reflective coating is more firmly and stably joined, and the reflective strip is easy to install, replace and maintain.

[0012] In the above-mentioned winch, one end of the belt shaft is coaxially connected with an anti-slip ratchet, and a bird-stopping piece is rotatably connected to the bracket, and the movable end of the bird-stopping piece always has a tendency to swing toward the outer periphery of the anti-slip ratchet so that the anti-slip ratchet can only rotate in one direction relative to the bracket; the other end of the belt shaft is fixedly provided with a limiting plate, and a coaxially arranged retaining ring is fixedly connected to the limiting plate, and a driving ratchet is provided between the retaining ring and the limiting plate, and a rotating cylinder coaxially connected to the driving ratchet is passed through the retaining ring, and a plurality of small bird-stopping pieces arranged at intervals around the circumference are rotatably connected to the limiting plate, and the movable ends of the small bird-stopping pieces always have a tendency to swing toward the outer periphery of the driving ratchet so that the driving ratchet can only rotate in one direction relative to the belt shaft, and the driving ratchet can drive the belt shaft to rotate synchronously via the small bird-stopping pieces. This helps the staff to keep the anti-slip ratchet locked with the bird stopper when driving the belt shaft to rotate and tension the binding belt, avoiding safety risks caused by reversal of the anti-slip ratchet. When the binding belt needs to be loosened, the bird stopper can be controlled to jump up. At the same time, the staff can operate the rotating drum to rotate to realize the rotation of the belt shaft, and controlling the rotating drum to rotate in the opposite direction will not drive the belt shaft to rotate synchronously. This helps the staff to control the reciprocating rotation of the rotating drum within a certain range to realize unidirectional rotation tension of the belt shaft, which is more in line with the staff's operating habits and improves operational safety and convenience.

[0013] In the above winch, the bird retaining member is located above the anti-slip ratchet, which is conducive to making the movable end of the bird retaining member tend to contact the anti-slip ratchet under the influence of gravity, and is conducive to the design of saving elastic components.

[0014] In the above winch, the retaining ring has an annular avoidance groove on one side facing the driving ratchet, and the avoidance groove is opposite to the driving ratchet along the axial direction of the retaining ring. This is conducive to uniformly reducing the friction area when the driving ratchet contacts the side of the retaining ring during rotation, avoiding excessive movement resistance of the driving ratchet while ensuring stable force on the driving ratchet, and ensuring smooth and convenient operation.

[0015] In the above winch, the belt shaft is cylindrical, and one end of the rotating drum extends into the inner cavity of the belt shaft. This is conducive to the position constraint of the rotating drum by the inner edge of the retaining ring and the inner cavity of the belt shaft during rotation, ensuring the stability of the movable range of the rotating drum, thereby ensuring the stability of the winch operation.

[0016] In the above winch, the side of the limit plate facing the driving ratchet has an annular groove arranged around the circumference, and the annular groove is opposite to the driving ratchet along the axial direction of the limit plate. Similarly, such annular groove can evenly reduce the friction area when the driving ratchet contacts the side of the limit plate during the rotation process, which is beneficial to reduce the movement resistance of the driving ratchet and ensure convenient operation.

[0017] Compared with the prior art, the advantages of the utility model are as follows:

[0018] The winch is provided with a transversely arranged mounting plate on the top of the bracket, and a reflective identification piece is provided on the mounting plate at a higher position. The reflective identification piece can produce obvious reflection of light from a higher position in a low illumination environment at night, so that the staff can more easily find and notice the position of the winch at night, so as to operate it or avoid it, thereby improving the safety and convenience of use.

[0029] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0030] Embodiment 1:

[0031] like Figure 1-4As shown, the winch includes a bracket 1 and a belt shaft 2 for winding the binding belt, the belt shaft 2 is rotatably connected to the bracket 1, the bracket 1 is gantry-shaped and includes a mounting plate 11 arranged horizontally at the top, the mounting plate 11 is vertically opposite to the belt shaft 2 below, and a strip-shaped reflective identification member 12 is fixed on the edge of the mounting plate 11. The bracket 1 can be fixed on the carrier, and the belt shaft 2 can rotate relative to the bracket 1 to tighten the binding belt thereon, thereby realizing the tensioning and binding of the binding belt; by setting the mounting plate 11 arranged horizontally on the top of the bracket 1, and setting the reflective identification member 12 on the mounting plate 11 at a higher position, the reflective identification member 12 can produce obvious reflection of light from a higher position in a low illumination environment at night, so that the staff can more easily find and notice the position of the winch at night, so as to operate or avoid it, thereby improving the safety and convenience of use. Specifically, the edge of the mounting plate 11 has a notch groove 111, and the reflective identification member 12 is embedded and fixed in the notch groove 111. In this way, the inner wall of the notch groove 111 is conducive to increasing the contact area between the reflective identification member 12 and the mounting plate 11 to make the connection stable. At the same time, after being hidden in the notch groove 111, the reflective identification member 12 is protected to a certain extent, which can reduce the probability of its damage by collision and ensure its normal and stable function. The reflective identification member 12 is a reflective strip pasted on the mounting plate 11. The reflective strip is easy to install and more convenient to replace and maintain. The cam 6 is provided with a plurality of camshafts 2, each of which is provided with a plurality of camshafts 3, each of which is provided with a plurality of camshafts 3. The camshafts 3 are provided with a plurality of camshafts 4, each of which is provided with a plurality of camshafts 3. The camshafts 3 are provided with a plurality of camshafts 4, each of which is provided with a plurality of camshafts 3. This is conducive to the staff to keep the anti-slip ratchet 3 locked with the bird-blocking member 4 when driving the belt shaft 2 to rotate and tension the binding belt, avoiding the safety risk caused by the reverse rotation of the anti-slip ratchet 3. When the binding belt needs to be loosened, the bird-blocking member 4 can be controlled to jump up. At the same time, the staff can operate the rotating drum 8 to rotate to realize the rotation of the belt shaft 2, and when the rotating drum 8 is controlled to rotate in the opposite direction, it will not drive the belt shaft 2 to rotate synchronously, which is conducive to the staff to control the reciprocating rotation of the rotating drum 8 within a certain range to realize the unidirectional rotation tension of the belt shaft 2, which is more in line with the staff's operating habits and improves the safety and convenience of operation. Preferably, the bird-blocking member 4 is located above the anti-slip ratchet 3.This is conducive to making the movable end of the bird retaining member 4 have a tendency to contact the anti-slip ratchet 3 under the influence of gravity, which is conducive to the design of saving elastic components. The side of the retaining ring 6 facing the driving ratchet 7 has an annular avoidance groove 61 that is arched toward the super outer side, and the avoidance groove 61 is opposite to the driving ratchet 7 along the axial direction of the retaining ring 6. This is conducive to uniformly reducing the friction area when the driving ratchet 7 contacts the side of the retaining ring 6 during rotation, and avoiding the driving ratchet 7 from being subjected to excessive movement resistance under the condition of ensuring the stable force of the driving ratchet 7, thereby ensuring smooth and convenient operation. The belt shaft 2 is cylindrical, and one end of the rotating cylinder 8 extends into the inner cavity of the belt shaft 2. This is conducive to the rotating cylinder 8 being able to obtain the position constraint of the inner edge of the retaining ring 6 and the inner cavity of the belt shaft 2 when rotating, ensuring the stability of the range of motion of the rotating cylinder 8, and then ensuring the stability of the winch operation. The limiting plate 5 has a circumferentially arranged annular groove 51 on the side of the driving ratchet 7, and the annular groove 51 is opposite to the driving ratchet 7 along the axial direction of the limiting plate 5. Similarly, the annular groove 51 can evenly reduce the friction area when the driving ratchet 7 contacts the side of the limit pan during rotation, which is beneficial to reducing the movement resistance of the driving ratchet 7 and ensuring convenient operation.

[0032] Embodiment 2:

[0033] like Figure 5 As shown, this embodiment is basically the same as the first embodiment, except that: the edge of the mounting plate 11 has a vertically protruding vertical plate 112, and the reflective identification member 12 is fixedly connected to the side of the vertical plate 112. In this way, the vertical plate 112 has a vertical thickness dimension greater than the thickness of the mounting plate 11 body, and will not affect the normal operation of the winch, which is conducive to increasing the arrangement area of ​​the reflective identification member 12, making it easier for the staff to find the winch position for operation or avoidance. The reflective identification member 12 is a reflective coating sprayed on the mounting plate 11, and the reflective coating is more firmly and stably joined.
