Technical Field
[0001] The utility model belongs to the technical field of winches and relates to a winch joint. Background Art
[0002] Before transporting goods by car, the goods need to be bundled to prevent the goods from falling off or colliding with each other during the driving process of the car, resulting in loss or damage. In order to ensure the firmness of the bundle, a winch structure is often required. When operating the winch, the tightening operation needs to be achieved by rotating the drive shaft. In order to make the operation more convenient for users, it is often necessary to install a winch joint on the drive shaft. The user uses the one-way clutch structure of the winch joint and only needs to continuously operate the winch joint to rotate back and forth within a comfortable angle range to achieve one-way tightening of the drive shaft.
[0003] For example, the applicant has previously developed a winch with authorization announcement number CN215711359U, which includes a winch shaft, a bird stopper and a welding ring fixedly connected to the end of the winch shaft, the welding ring is connected to a guard ring, the guard ring is rotatably connected to a rotating cylinder for inserting a crowbar, the guard ring is provided with a plurality of mounting grooves axially along the winch shaft, the mounting grooves are arranged one-to-one with the bird stopper, and the bird stopper is rotatably arranged in the corresponding mounting groove, the rotating cylinder and the welding ring are respectively arranged on the left and right sides of the guard ring and limit the bird stopper in the corresponding mounting groove.
[0004] The above structure is easy to use, but the limit plate of the rotating cylinder is positioned on the protective ring by the pressure ring, and a sealing ring is arranged between the limit plate and the pressure ring. When the rotating cylinder rotates, the resistance is large and the sealing ring will be continuously worn. When maintenance and replacement are required, the pressure ring and the protective ring are often fixedly connected by welding and are difficult to separate, resulting in maintenance difficulties. Summary of the invention
[0005] The utility model aims at the above problems existing in the prior art and provides a winch joint. The technical problem to be solved by the utility model is that the existing winch joint parts are easy to wear and difficult to maintain.
[0006] The purpose of the utility model can be achieved through the following technical solutions:
[0007] A winch joint comprises a rotating shaft and a coaxially arranged sleeve, wherein the rotating shaft is axially fixed in the sleeve, and a plurality of bird-stopping members arranged circumferentially around the sleeve are provided between the outer periphery of the rotating shaft and the sleeve. The present invention is characterized in that the outer sleeve of the rotating shaft is provided with two retaining springs and two annular friction-reducing pads, the two retaining springs and the two friction-reducing pads are arranged at intervals along the axial direction of the rotating shaft, the inner edge of the sleeve has two circumferentially arranged positioning grooves, the retaining springs are respectively positioned and embedded in the positioning grooves, the two friction-reducing pads are both located between the two retaining springs, and the bird-stopping members are both limitedly arranged between the two friction-reducing pads.
[0008] By arranging two retaining springs and two friction-reducing pads on the outer periphery of the rotating shaft, the bird stopper is limitedly arranged between the two friction-reducing pads, and the two retaining springs cooperate with the positioning grooves on the inner edge of the sleeve to form axial positioning and thus limit the positions of the two friction-reducing pads. In this way, the friction-reducing pads can shield the matching position of the bird stopper. At the same time, when the rotating shaft rotates, the friction-reducing pads can rotate with the bird stopper with edges to ensure smooth rotation, reduce component wear, and extend the maintenance cycle. When maintenance is needed, the deformation of the free end of the retaining spring can be controlled by using tools to disengage from the positioning groove, and then the internal components can be maintained, making maintenance more convenient.
[0009] In the above-mentioned winch joint, the outer periphery of the rotating shaft has a plurality of mounting grooves evenly spaced around the circumference, one end of the bird stopper is a hinged part and is rotatably connected in the mounting groove, the inner edge of the sleeve has a plurality of inner racks arranged along the axial direction and evenly arranged around the circumference, the other end of the bird stopper is a swinging part and is located between the inner racks, the swinging part and the side surface of the inner rack abut against each other along the circumferential limit of the sleeve, the outer periphery of the rotating shaft is also connected with an elastic reset part abutting against the swinging part, and when the rotating shaft rotates relative to the sleeve, the swinging part swings toward the side where the elastic reset part is located. In this way, the rotating shaft can drive the sleeve to rotate synchronously through the bird stopper, and the elastic reset part can make the swinging part of the bird stopper snap between the inner racks to prepare for the subsequent synchronous rotation state after the rotating shaft rotates relative to the sleeve, so as to meet the function of the one-way drive of the joint, in addition, the bird stopper and the elastic reset part are both connected to the outer periphery of the rotating shaft, and when the bird stopper and the elastic reset part are installed, the external space is larger for observation, which is conducive to improving the assembly accuracy.
[0010] In the above winch joint, the positioning grooves are all formed on the inner rack, so that the housing slides along the surface of the inner rack before the retaining ring is inserted into the positioning groove, which helps to reduce sliding resistance and ensures convenient assembly.
[0011] In the above-mentioned winch joint, the outer circumference of the rotating shaft has a plurality of limit blocks evenly spaced around the circumference, the number of the installation grooves is consistent with the number of the limit blocks, the installation grooves are respectively located on each limit block and penetrate the limit block along the axial direction of the sleeve, and the side of the swinging part away from the elastic reset member is limitedly abutted against the limit block connected to the bird stopper. In this way, the installation groove is arranged on the limit block and penetrates the limit block, which is convenient for workers to embed the bird stopper into the installation groove along the axial direction of the rotating shaft from both sides according to needs during assembly, and the assembly is convenient. At the same time, the swinging part is limitedly abutted against the connected limit block under the action of the elastic reset member. At this time, the swinging part is positioned before being installed in the sleeve, so that the bird stopper can be just embedded between the inner racks during the process of installing the rotating shaft into the sleeve, so that the operation is smooth and the assembly efficiency is further guaranteed.
[0012] In the above winch joint, the outer circumference of the rotating shaft also has a plurality of slots arranged at intervals along the circumferential direction, and the elastic reset member includes a sheet-shaped elastic part and a U-shaped clamping part, the elastic part is connected to the clamping part, the clamping part is positioned and clamped in the slot, and the elastic part abuts against the bird stopper. In this way, the U-shaped clamping part can be more easily clamped into the slot by force deformation to achieve convenient installation, and the elastic part can provide reset for the bird stopper by deformation.
[0013] In the above winch joint, the outer periphery of the rotating shaft is also sleeved with an annular cover, the cover is located on the outside of the clip, and the outer edge of the cover has a plurality of external teeth, which mesh with the internal rack. In this way, the cover can provide protection for the clip from the outside, reduce the intrusion of foreign impurities and dirt into the working area of the bird retaining member, and the meshing of the external teeth with the internal rack can ensure the stability of the cover position.
[0014] In the above winch joint, a connecting bolt is radially penetrated at one end of the sleeve away from the rotating shaft, and a cylindrical soft bushing is sleeved on the outer circumference of the connecting bolt. In this way, when the sleeve is connected to the outer end of the winch drive shaft through the connecting bolt, it is beneficial to contact the winch drive shaft through the soft bushing to provide buffering, avoid rapid damage due to rigid contact between the connecting bolt and the winch drive shaft, and ensure the service life.
[0015] In the above winch joint, the inner edge of the sleeve away from the rotating shaft end is fixedly connected with a plurality of rubber pads arranged around the circumference. This is conducive to the rubber pads being in contact with the winch drive shaft when the sleeve is fixed to the outer periphery of the winch drive shaft, and when the sleeve moves slightly around the winch drive shaft, it will not directly rub against it, but can be achieved through the deformation of the rubber pads, thereby improving the quiet effect and service life.
[0016] Compared with the prior art, the advantages of the utility model are as follows:
[0017] The rotating shaft in the winch joint rotates smoothly and the parts loss is low, and the maintenance cycle is longer. When maintenance is needed, the deformation of the free end of the retaining spring can be controlled by using tools to disengage from the positioning groove, and then the internal parts can be maintained, which makes maintenance more convenient and worry-free.

[0032] 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.
[0033] like Figure 1-4 , Figure 6As shown, the winch joint includes a rotating shaft 1 and a coaxially arranged sleeve 2, the rotating shaft 1 is axially fixed in the sleeve 2, eight elastic reset members 3 and bird stop members 4 are arranged evenly spaced around the circumference of the sleeve 2 between the outer periphery of the rotating shaft 1 and the sleeve 2, the outer periphery of the rotating shaft 1 has eight mounting grooves 11 evenly spaced around the circumference, one end of the bird stop member 4 is a hinged portion 41 and is rotatably connected to the mounting groove 11, the elastic reset member 3 is connected to the outer periphery of the rotating shaft 1 and is close to the rotating shaft with the bird stop member 4 1, the inner edge of the sleeve 2 has twenty-four inner racks 21 arranged along the axial direction and evenly arranged around the circumference, the inner racks 21 extend around the circumference of the sleeve 2, the other end of the bird-blocking member 4 is a swinging portion 42 and is located between two adjacent inner racks 21, the swinging portion 42 of the bird-blocking member 4 and the side surface of the inner rack 21 are abutted against the circumferential limit of the sleeve 2, when the rotating shaft 1 rotates relative to the sleeve 2, the swinging portion 42 of the bird-blocking member 4 swings toward the side where the elastic reset member 3 is located. One end of the sleeve 2 is used to be fixedly connected to the driving shaft 101 of the winch, and the rotating shaft 1 is used for the operator to realize rotation by applying force through the connecting rocker arm. A swingable bird stopper 4 is set between the rotating shaft 1 and the sleeve 2 to realize the unidirectional rotation of the sleeve 2. The bird stopper 4 itself can be an existing strip or plate-shaped structure. In this way, the operator only needs to control the reciprocating rotation of the rotating shaft 1 within a certain angle range to realize the continuous rotation of the sleeve 2 in the specified direction to realize the winding of the winch, which is more convenient to operate. The elastic reset button is used to provide a reset force for the bird stopper 4 to ensure that the bird stopper 4 always has a tendency to limit the rotating shaft 1 and the sleeve 2 during the reciprocating rotation of the rotating shaft 1; by setting eight circumferentially evenly spaced mounting grooves 11 on the outer periphery of the rotating shaft 1, the hinged portion 41 of the bird stopper 4 is rotatably connected to the mounting groove 11 The spring 22 is provided with a spring 24 which is arranged on the inner edge of the sleeve 2 so that the swinging portion 42 of the bird stopper 4 is located between the inner racks 21 and abuts against the side surface of the inner rack 21 along the circumferential direction of the sleeve 2. In this way, the sleeve 2 can be driven to rotate synchronously through the bird stopper 4, and the spring 24 is arranged between the inner racks 21 to prepare for the subsequent synchronous rotation state after the shaft 1 rotates relative to the sleeve 2. In addition, the bird stopper 4 and the spring 24 are connected to the outer periphery of the shaft 1. When the bird stopper 4 and the spring 24 are installed, the external space is large enough to reduce interference during assembly and facilitate observation, thereby improving assembly convenience and assembly accuracy. Specifically, the outer periphery of the rotating shaft 1 has eight limit blocks 12 evenly spaced around the circumference, the mounting groove 11 is respectively located on each limit block 12 and penetrates the limit block 12 along the axial direction of the sleeve 2, and the side of the bird stopper 4 away from the elastic reset member 3 is limitedly abutted against the limit block 12 along the swinging direction of the bird stopper 4.In this way, the mounting groove 11 is arranged on the limit block 12 and passes through the limit block 12, so that the worker can easily embed the bird-blocking member 4 into the mounting groove 11 along the axial direction of the rotating shaft 1 during assembly, and the assembly is convenient. At the same time, the bird-blocking member 4 is limitedly pressed against the limit block 12 under the action of the elastic reset member 3. At this time, since the bird-blocking member 4 is also located between the inner racks 21, that is, the bird-blocking member 4 can be inserted between the inner racks 21 during the process of being installed into the sleeve 2, it is further ensured that the bird-blocking member 4 can be smoothly installed into the sleeve 2 so that the bird-blocking member 4 cooperates with the inner rack 21. Preferably, the limit block 12 also has eight slots 13 arranged at intervals along the circumferential direction, and the elastic reset member 3 includes a sheet-shaped elastic portion 31 and a U-shaped clamping portion 32, the elastic portion 31 is connected to the clamping portion 32, and the clamping portion 32 is positioned and clamped in the slot 13, and the elastic portion 31 is pressed against the bird-blocking member 4. In this way, the U-shaped clamping portion 32 can be clamped into the clamping slot 13 by being deformed by force to achieve convenient installation, and the elastic portion 31 can be deformed to provide reset for the bird stopper 4.
[0034] like Figure 1 , Figure 5-7 As shown, the outer periphery of the rotating shaft 1 is sleeved with two retaining springs 5, and the two retaining springs 5 are arranged on both sides of all the bird-blocking parts 4 along the axial direction of the rotating shaft 1. The inner edge of the sleeve 2 has two positioning grooves 22 arranged around the circumference, and the retaining springs 5 are positioned and embedded in the positioning grooves 22, and the positioning grooves 22 are all opened on the inner rack 21. In this way, the retaining springs 5 can expand and embed into the notch groove to form a positioning after being installed in the sleeve 2, which is convenient for installation. Then, the bird-blocking parts 4 are constrained between the two retaining springs 5 by the two retaining springs 5 to avoid falling out to ensure the stability of installation and operation. At the same time, the retaining springs 5 can be easily disassembled during maintenance, which is convenient for maintenance. Further, the outer periphery of the rotating shaft 1 is also sleeved with two annular friction-reducing pads 6, and the two friction-reducing pads 6 are located between the two retaining springs 5 and are arranged on both sides of all the bird-blocking parts 4. In this way, during the rotation of the rotating shaft 1 relative to the sleeve 2, the bird-blocking parts 4 will contact with the friction-reducing pads 6 to avoid direct wear on the retaining springs 5. At the same time, the friction-reducing pads 6 can rotate automatically to ensure smooth rotation and improve the service life of the joint. Two annular covers 7 are also sleeved on the periphery of the rotating shaft 1. The two covers 7 are respectively located on the outside of the two clamping springs 5. The outer edges of the covers 7 have twenty-four external teeth 71, which mesh with the internal racks 21. In this way, the covers 7 can provide protection for the clamping springs 5 from the outside, reduce the intrusion of foreign impurities and dirt into the working area of the bird retaining member 4, and the meshing of the external teeth 71 with the internal racks 21 can ensure that the cover 7 is firmly positioned.
[0035] like Figure 1 , Figure 2 , Figure 5-7As shown, a connecting bolt 8 is radially penetrated at one end of the sleeve 2 away from the rotating shaft 1, and a cylindrical soft bushing 9 is sleeved on the outer periphery of the connecting bolt 8, and the soft bushing 9 can be a rubber part. In this way, when the sleeve 2 is connected to the outer end of the winch drive shaft 101 through the connecting bolt 8, it is beneficial to contact the winch drive shaft 101 through the soft bushing 9 to provide buffering, avoid the connection bolt 8 and the winch drive shaft 101 from being quickly damaged by rigid contact, and ensure the service life. The inner edge of the end of the sleeve 2 away from the rotating shaft 1 is fixedly connected with a plurality of rubber pads 10 arranged around the circumference. In this way, when the sleeve 2 is fixed to the outer periphery of the winch drive shaft 101, the rubber pad 10 will not directly rub against it when the sleeve 2 moves slightly circumferentially relative to the winch drive shaft 101, but can be achieved through the deformation of the rubber pad 10, thereby improving the mute effect and service life.
