DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The utility model provides Figure 1 - Figure 6 The metal chain assembly shown comprises a traction chain 1,

[0024] A plurality of honeycomb hollow grooves are equidistantly arranged on both sides of the traction chain 1, which effectively reduces the weight of the traction chain 1 without any adverse effect on its carrying capacity. The traction chain 1 is a chain mainly used for pulling and lifting, and fixing various loads. It is also called a traction chain or a lifting chain, which is differentiated according to different occasions of use. Its main function is to move objects slowly and intermittently through a distance, or to maintain the load when not moving. The traction chain 1 is usually moved back and forth during use, rather than a complete cycle. Therefore, it has both transmission and conveying functions.

[0025] The traction chain 1 is provided with a hanging part 2 for carrying objects, which can mainly adopt a quick disassembly mechanism. The lifting lug 202 can be easily installed on the traction chain 1, simplifying the installation and disassembly steps. When no objects are hung, the lifting lug 202 can be easily removed, reducing the weight and burden, extending the life of the traction chain 1, and improving its flexible switching ability between different working scenes, thereby expanding the scope of use. In addition, the rotatable design of the lifting lug 202 facilitates the adjustment of the angle or rotation of the object on the hanging part 2, enhancing the flexibility and convenience of the object;

[0026] The hanging part 2 includes a mounting seat 201, and one end of the mounting seat 201 close to the bearing 205 is open. The mounting seat 201 is made of hard material to ensure the stability of its structure and has a certain deformation ability.

[0027] There are multiple mounting seats 201 that are equidistantly slidably arranged on the surface of the traction chain 1. A lifting lug 202 is installed on the inner wall of the mounting seat 201. A hanging groove 203 is provided on the lifting lug 202. The arrangement of the hanging groove 203 enhances the stability and fixing effect of the object on the lifting lug 202.

[0028] The surface of the traction chain 1 is provided with a plurality of equally spaced mounting grooves 204, a bearing 205 is provided in the mounting groove 204, the outer wall of the mounting seat 201 is in squeeze contact with the inner wall of the bearing 205, a threaded hole 206 is provided at one end of the mounting seat 201 away from the bearing 205, and the lifting lug 202 is threadedly connected to the mounting seat 201 through the threaded hole 206;

[0029] When the lifting lug 202 needs to be installed, the mounting seat 201 is inserted into the inner wall of the bearing 205, and then the lifting lug 202 is screwed into the mounting seat 201 by rotating it clockwise. When the lifting lug 202 is screwed into the mounting seat 201, the bottom opening of the mounting seat 201 is squeezed by the lifting lug 202 and expands to both sides, and the opening of the mounting seat 201 expands to both sides and contacts the inner wall of the bearing 205. When the lifting lug 202 is tightened on the mounting seat 201, the installation of the lifting lug 202 is completed, and then the object can be put on the hanging slot 203.

[0030] When the lifting ear 202 needs to be disassembled, the lifting ear 202 is disconnected from the mounting seat 201 by rotating it counterclockwise, and then the lifting ear 202 is pulled out of the mounting seat 201. When the lifting ear 202 is pulled out of the mounting seat 201, the bottom of the mounting seat 201 recovers its deformation and does not contact the inner wall of the bearing 205. At this time, the mounting seat 201 can be pulled out of the mounting groove 204.

[0031] The utility model also provides a metal chain transmission structure, including a support frame 3 and a sprocket 4, the sprocket 4 is rotatably arranged on the outer side wall of the support frame 3, the traction chain 1 is movably arranged on the sprocket 4, and a lubrication component 5 for lubricating the traction chain 1 is arranged on the surface of the support frame 3, which can automatically trigger the lubrication process when the traction chain 1 rotates, without manually applying lubricating oil. When the traction chain 1 contacts the lubrication component 5, the sponge 507 will release an appropriate amount of lubricating oil to ensure that the traction chain 1 is properly lubricated, and when the traction chain 1 does not contact the lubrication component 5, the lubricating oil will not be released, thereby avoiding waste;

[0032] The lubrication assembly 5 includes a storage tank 501, which is slidably arranged on the surface of a support frame 3, and the inner wall of the storage tank 501 is provided with a compartment 502, the inner wall of the compartment 502 is provided with a liquid outlet 503, and the inner wall of the compartment 502 is slidably provided with a discharge pipe 504;

[0033] A baffle 505 is provided at one end of the discharge pipe 504 close to the compartment 502, a through hole 506 is provided on the surface of the baffle 505, the through hole 506 is connected to the discharge pipe 504, the baffle 505 is in contact with the liquid outlet 503, a sponge 507 is provided at one end of the discharge pipe 504 away from the compartment 502, the discharge pipe 504 is connected to the sponge 507, a first spring 508 is provided on the inner wall of the compartment 502, one end of the first spring 508 is fixed to the discharge pipe 504;

[0034] A moving part 6 for moving the storage tank 501 is provided on one side of the support frame 3 close to the storage tank 501, mainly for facilitating the movement of the storage tank 501 and limiting the position of the storage tank 501 when lubricating the traction wheel;

[0035] The moving part 6 includes a sliding groove 601, which is provided on a side of the support frame 3 close to the storage tank 501. A second spring 602 is provided on the inner wall of the sliding groove 601. One end of the second spring 602 is fixed to the storage tank 501. A plurality of equally spaced limiting grooves 603 are provided on the side of the support frame 3 close to the storage tank 501. A fixing block 604 is provided on the side of the storage tank 501 close to the limiting groove 603. A limiting rod 605 is slidably provided on the inner wall of the fixing block 604. The limiting rod 605 is plugged into the limiting groove 603.

[0036] Working principle: When the traction chain 1 needs to be lubricated, the limit rod 605 and the limit groove 603 are released, and the storage tank 501 is pushed to slide in the direction of the traction chain 1. At this time, the second spring 602 is compressed. When the storage tank 501 slides and causes the sponge 507 to contact the traction chain 1, the limit rod 605 is aligned with one of the limit grooves 603, and the limit rod 605 is pushed to insert into the limit groove 603. At this time, the outer wall of the traction chain 1 contacts the sponge 507, and the contact of the traction chain 1 makes the discharge pipe 504 contact the compartment 502. When the traction chain 1 contacts the lubrication group When the first spring 508 is in contact with the first component 502, the sponge 507 will continuously contact and slide with it, so that the discharge pipe 504 slides back and forth in the compartment 502. During the sliding process, the discharge pipe 504 compresses the first spring 508 and is reset by the first spring 508, so that the through hole 506 on the baffle plate is sometimes connected and sometimes disconnected with the liquid outlet hole 503. Once the through hole 506 is connected with the liquid outlet hole 503, the lubricating oil in the storage tank 501 will flow into the through hole 506 and into the sponge 507 through the discharge pipe 504, so that the sponge 507 can release the lubricating oil in time to provide necessary lubrication for the traction chain 1.

[0037] After the lubrication of the traction chain 1 is completed, the limiting relationship between the limiting rod 605 and the limiting groove 603 is released, so that the second spring 602 can restore its deformation and push the storage tank 501 to reset. Then, the limiting rod 605 is reinserted into the limiting groove 603 for limiting. At this time, the storage tank 501 has been reset, and the sponge 507 thereon is no longer in contact with the traction chain 1. Since the sponge 507 is separated from the traction chain 1, the lubricating oil in the storage tank 501 will no longer be released.
