Description

Technical Field

[0001] This utility model relates to the technical field of hand chain hoist equipment, specifically a chain output structure for a VX type hand chain hoist with guide wheels. Background Technology

[0002] As a widely used manual lifting machine, the hand chain hoist plays a crucial role in lifting and handling goods in many places such as factories, mines, construction sites, and docks. With its advantages of simple operation and easy portability, it has become the preferred equipment for short-distance lifting operations.

[0003] However, with existing chain hoists, the chain often gets stuck inside the protective cover during rapid pulling, forcing work to stop. Repairing this requires removing the protective cover to clear the jammed chain, which slows down the work process. Furthermore, when pulling the chain quickly, it often scrapes against the sides of the cover, quickly wearing them down to the point of being unusable, thus reducing the cover's lifespan.

[0004] Therefore, a chain output structure with guide wheel for a VX type hand chain hoist is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a chain output structure for a VX-type hand chain hoist with guide wheels. By designing a guiding mechanism, a guide post is used to guide the hand chain, which solves the problem that the hand chain often gets stuck inside the protective cover during rapid pulling, forcing work to stop due to the jammed hand chain. During maintenance, the protective cover needs to be removed to clear the jammed hand chain. However, frequent disassembly of the hand chain hoist slows down the progress of the project. Furthermore, when the hand chain is pulled quickly, it often scrapes against the sides of the cover, and the sides of the cover will soon be worn down and unusable, reducing the lifespan of the cover.

[0006] To achieve the above objectives, the present invention provides the following technical solution: including a housing, a hand cover is provided on the side of the housing, a hand chain wheel is provided between the hand cover and the housing, a rotating outer ring is provided on the side of the hand chain wheel, and at least two mounting grooves are provided on both the rotating outer ring and the side of the housing, the two mounting grooves are symmetrically distributed, and a guide post is provided in the mounting groove;

[0007] The hand chain wheel is equipped with a guiding mechanism via the guide post. The guiding mechanism includes a hand chain, a fixed inner ring, at least two fixing grooves, at least two internal hexagonal head screws, and a chain groove.

[0008] Preferably, the fixed inner ring is located on the side of the rotating outer ring, one side of the fixed inner ring is fixedly connected to the side of the rotating outer ring, and the other side of the fixed inner ring is fixedly connected to the side of the housing.

[0009] Preferably, the chain groove is formed on the side of the hand chain wheel, the hand chain is sleeved on the chain groove, and the hand chain meshes with the hand chain wheel.

[0010] Preferably, one side of the hand chain wheel is rotatably connected to the side of the rotating outer ring.

[0011] Preferably, the two guide posts are located on both sides of the hand chain, and the hand cover is made of aluminum alloy.

[0012] Preferably, at least two fixing grooves are provided on the side of the hand cover and the side of the rotating outer ring, and the two fixing grooves are symmetrically distributed.

[0013] Preferably, the two socket head cap screws are symmetrically distributed, and the socket head cap screws are threadedly connected to the fixing groove.

[0014] Compared with the prior art, this utility model provides a chain output structure for a VX-type hand chain hoist with a guide wheel, which has the following beneficial effects:

[0015] 1. When the hand chain is pulled to rotate the hand chain wheel, the hand chain will first contact the guide post and will not directly contact the side of the hand cover, which reduces wear on the hand cover and improves the service life of the hand cover.

[0016] 2. When the hand chain is pulled, the hand chain will contact the guide post, and because the hand chain is under force, it will be taut on the guide post, which reduces the possibility of the hand chain getting stuck in the hand cover when rotating, thus improving work efficiency.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example:

[0024] Please see Figure 1 - Figure 4 The chain output structure of a VX type hand chain hoist with guide wheel in this embodiment includes a housing 1, a hand cover 2 is provided on the side of the housing 1, a hand chain wheel 3 is provided between the hand cover 2 and the housing 1, a rotating outer ring 5 is provided on the side of the hand chain wheel 3, and at least two mounting grooves 101 are provided on both the rotating outer ring 5 and the side of the housing 1. The two mounting grooves 101 are symmetrically distributed, and a guide post 6 is provided in the mounting groove 101.

[0025] The hand chain wheel 3 is equipped with a guiding mechanism via the guide post 6. The guiding mechanism includes a hand chain 4, a fixed inner ring 103, at least two fixed grooves 7, at least two internal hexagonal head screws 8, and a chain groove 102.

[0026] When starting work, first pull the hand chain 4. Under the action of the guide mechanism, the hand chain 4 will drive the hand chain wheel 3 to rotate, so that the hand chain wheel 3 can drive the subsequent device to rotate. When rotating the hand chain 4, due to the action of the guide mechanism, the hand chain 4 will first contact the guide post 6, and will not directly contact the side of the hand cover 2. Because the hand chain 4 is prone to deformation under force, when pulling the hand chain 4 quickly or at an angle, the hand chain 4 will contact the side of the hand cover 2 and cause wear to the hand cover 2. The guide post 6 is designed so that the hand chain 4 will first drive the guide post 6 to rotate, avoiding direct contact with the side of the hand cover 2, thus reducing wear on the hand cover 2. In addition, because the guide post 6 guides the rotation of the hand chain 4, the hand chain 4 is less likely to get stuck inside the hand cover 2.

[0027] At this point, the hand zipper 4 is guided, preventing it from getting stuck inside the hand cover 2 due to rapid rotation. If it gets stuck, the hand cover 2 needs to be disassembled to clear the blockage. This solves the problem and avoids the need to frequently disassemble the hand cover 2 to clear the blockage during work, thus improving work efficiency. Furthermore, because the guide post 6 limits the position of the hand zipper 4, it prevents the hand zipper 4 from deforming under force and wearing down the side of the hand cover 2, thus extending the service life of the hand cover 2.

[0028] The fixed inner ring 103 is located on the side of the rotating outer ring 5. One side of the fixed inner ring 103 is fixedly connected to the side of the rotating outer ring 5, and the other side of the fixed inner ring 103 is fixedly connected to the side of the housing 1.

[0029] The chain groove 102 is formed on the side of the hand chain wheel 3, and the hand chain 4 is sleeved on the chain groove 102 and meshes with the hand chain wheel 3;

[0030] In this configuration, since the chain wheel 3 is rotatably connected to the outer rotating ring 5, and the outer rotating ring 5 is fixedly connected to the inner fixed ring 103, the chain wheel 3 will not drive the outer rotating ring 5 to rotate when it rotates. The two guide posts 6 on the outer rotating ring 5 will limit and guide the zipper chain 4. Since the zipper chain 4 is engaged with the chain wheel 3, the zipper chain 4 will drive the chain wheel 3 to rotate when it rotates.

[0031] At this time, the outer ring 5 is limited, and the positions of the guide post 6 and the hand chain 4 are also fixed to avoid the problem of the outer ring 5 rotating due to the rotation of the hand chain wheel 3, thus improving the stability of the device.

[0032] One side of the chain wheel 3 is rotatably connected to the side of the rotating outer ring 5;

[0033] Two guide posts 6 are located on both sides of the hand chain 4, and the hand cover 2 is made of aluminum alloy;

[0034] At least two fixing grooves 7 are provided on the side of the hand cover 2 and the side of the rotating outer ring 5, and the two fixing grooves 7 are symmetrically distributed.

[0035] Two socket head cap screws 8 are symmetrically distributed, and the socket head cap screws 8 are threadedly connected to the fixing groove 7;

[0036] Because the hand cover 2 is made of aluminum alloy, it is easily worn by the zipper 4. Therefore, when the zipper 4 drives the hand chain wheel 3 to rotate, the two guide posts 6, located on either side of the zipper 4, will first contact the guide posts 6 when the zipper 4 is taut or deformed, causing the guide posts 6 to rotate. Since the guide posts 6 are spaced apart from the sides of the hand cover 2, the zipper 4 will not directly contact the sides of the hand cover 2, thus avoiding the problem of the zipper 4 directly contacting the sides of the hand cover 2. Furthermore, because the two guide posts 6 guide the zipper 4... The function is that when the hand chain 4 generates force, it will be straightened by contact with the guide post 6, reducing the possibility of it getting stuck in the hand cover 2. When it is necessary to disassemble the hand cover 2, the hex socket head cap screw 8 is turned. Since both the hand cover 2 and the rotating outer ring 5 have fixing grooves 7, when the hex socket head cap screw 8 is disengaged from the fixing groove 7 on the rotating outer ring 5, the fixing between the hand cover 2 and the rotating outer ring 5 is made into contact, and the hand cover 2 can be removed from the rotating outer ring 5. When it is necessary to install, the hex socket head cap screw 8 is aligned with the fixing groove 7 on the rotating outer ring 5 and turned to fix the rotating outer ring 5 and the hand cover 2.

[0037] At this point, the rotating outer ring 5 and the hand cover 2 are quickly disassembled, making it faster to disassemble the hand cover 2 when needed. Furthermore, due to the characteristics of the fixing groove 7 and the internal hexagonal head screw 8, the fixation between the hand cover 2 and the rotating outer ring 5 is more secure.

[0038] The installation method, connection method, or setting method disclosed in this embodiment are all common mechanical connections.

[0039] Any connection method that can achieve its beneficial effect can be implemented, so the specific structural composition and working principle will not be described in detail in this embodiment.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
