Description

Technical Field

[0001] This utility model relates to the technical field of transmission chain devices, specifically a corrosion-resistant transmission chain. Background Technology

[0002] In the industrial field, transmission chains refer to chains used for power transmission and material handling. They are widely used in various machinery and equipment, such as motorcycles, bicycles, conveyor belts, and elevators. As a key mechanical component, they can effectively transmit power and motion. They consist of a series of chain links, each of which includes two sprockets (with teeth) connected by pins. The chain can roll on the sprockets to transmit power and motion. They can be further classified into roller chains and toothed chains, etc. Different types play different roles in different fields.

[0003] For example, a corrosion-resistant chain with announcement number CN218992236U includes a front plate, a rear plate, and a connecting plate. Holes are formed on both the left and right sides of the front and rear plates. The left hole of the front plate is nested and fixed to the left hole of the rear plate via a shaft sleeve. The right hole of the front plate is connected to the connecting plate. Rings are fixed to the front end of the front plate and the rear end of the rear plate. A sleeve is nested on the outer wall of the shaft sleeve. Ring grooves are formed at the front and rear of the shaft sleeve, and these grooves engage with the corresponding rings. The right hole of the front plate is nested and fixed to the right hole of the rear plate via the shaft sleeve. The structures of the front and rear plates are symmetrical and identical. Locking holes are formed on both the left and right sides of the connecting plate. The position of the locking hole on the left side corresponds sequentially to the right hole of the front plate and the right hole of the rear plate.

[0004] The aforementioned device, through the arrangement of the shaft sleeve, sleeve, ring body, and ring groove, prevents external dust particles from entering between the shaft sleeve and sleeve, thus avoiding increased friction. This helps prevent dust particles and dirt from entering the nested structure of the chain, further reducing chain friction and extending chain lifespan. However, during chain use, lubricating oil is often required. The relatively tight nested structure of the aforementioned device makes it difficult to add lubricating oil, potentially leading to greater internal friction and more damage to the inner ring body, thereby reducing the chain's lifespan. Utility Model Content

[0005] The purpose of this invention is to provide a corrosion-resistant transmission chain to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a corrosion-resistant transmission chain, comprising a shaft chain body, a connecting collar assembled at the front end of the shaft chain body, and a sleeve body assembled at the rear end of the shaft chain body. A sleeve opening is provided on the surface of the sleeve body, an insertion opening is provided in the middle of the connecting collar, and a recessed layer is provided on the surface of the insertion opening. An anti-corrosion surface layer is coated on the surface of the shaft chain body, thickened layers are provided on both sides of the sleeve body, and a side recessed edge is provided on the inner side of the sleeve body. A connecting bolt structure is assembled in the middle of the sleeve body.

[0007] Preferably, the two sides of the connecting bolt structure are fitted with connecting ends, and the outer surface of the connecting ends is provided with a notch, and the inside of the notch is provided with a threaded opening.

[0008] Preferably, a push block is fitted on the inner surface of the connecting end, and a connecting rod is fitted in the middle of one side of the connecting end, with a threaded post fitted at the front end of the connecting rod.

[0009] Preferably, an outer sleeve is fitted in the middle of the other side of the connecting end, and the inner surface of the outer sleeve is provided with meshing grooves.

[0010] Preferably, a friction ring is fitted onto the fitting opening, and the surface of the friction ring is provided with a pressing end.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. Compared to other transmission chains, this device adopts a unidirectional shaft chain design, which prevents the components of the device from affecting each other. The transmission chains are embedded with connecting bolts to effectively fix the connection between them. Friction rings are installed on both sides of the connecting shaft end. The friction rings are used to offset the rotational damage of the connecting shaft end. In addition, the friction rings can also act as a carrier for lubricant, effectively retaining the lubricant on the surface for better internal lubrication. By avoiding damage in multiple ways, the anti-corrosion layer on the surface of the shaft chain body can be prevented from leaking, and it can better withstand the corrosive effects of air.

[0013] 2. In addition, the device has a simple structure, which makes it very convenient to repair or replace a certain component. The independent design means that subsequent disassembly can be carried out individually, with fewer steps and simpler operation compared to other devices. Attached Figure Description

[0018] 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.

[0019] Please see Figures 1 to 3 This utility model provides a technical solution:

[0020] refer to Figure 1 The main body is a shaft chain body 6. The front end of the shaft chain body 6 is equipped with a connecting collar 2, and the rear end of the shaft chain body 6 is equipped with a sleeve body 4. The sleeve body 4 and the connecting collar 2 serve as a carrier for mutual connection. Each set of shaft chain bodies 6 is assembled between sleeve bodies 4 through the front connecting collar 2, and is fixedly connected with other fixing structures. The surface of the sleeve body 4 is provided with a fitting opening, and the middle of the connecting collar 2 is provided with an insertion opening. The surface of the insertion opening is provided with a recessed layer 1. The surface of the shaft chain body 6 is coated with an anti-corrosion surface layer 3. The design of the anti-corrosion surface layer 3 can increase the corrosion resistance of this transmission chain and extend its service life. The two sides of the sleeve body 4 are provided with thickening layers 5. The thickening layers 5 are made of stainless steel. Most of the structures on both sides are corroded by long-term contact with air, but stainless steel has strong corrosion resistance and can withstand air corrosion. The inner side of the sleeve body 4 is provided with a side recessed edge, and a connecting bolt structure is assembled in the middle of the sleeve body 4.

[0021] refer to Figure 2 , 3The main body is a bolt structure. Connecting ends 14 are mounted on both sides of the bolt structure. The outer surface of each connecting end 14 has a notch, and inside the notch is a threaded opening 15. The threaded opening 15 facilitates rotational engagement by a thread cutter, simplifying subsequent assembly. A push block 7 is mounted on the inner surface of the connecting end 14. A connecting rod 13 is mounted in the middle of one side of the connecting end 14, and a threaded post 12 is mounted at the front end of the connecting rod 13. An outer sleeve 8 is mounted in the middle of the other side of the connecting end 14, and the inner surface of the outer sleeve 8 has engagement grooves 11, enabling the outer sleeve 8 to rotate and be fixed with the threaded post 12. A friction ring 9 is mounted on the sleeve opening. The surface of the friction ring 9 has a pressing end 10. The friction ring 9 is mounted inside the sleeve opening, and part of it is recessed. The friction ring 9 is positioned in the recessed position of the sleeve opening, and its surface has a pressing end 10. The pressure end 10 is designed to facilitate the contact of the push block 7 with the friction ring 9, which pushes the friction ring 9 inward. Since the connecting collar 2 is smaller than the sleeve body 4, there will inevitably be a gap between them under normal fixing, and collisions will inevitably occur during the transport of the transmission chain. This will accelerate the damage to the surface anti-corrosion layer. However, by utilizing the design of the friction ring 9, and with the push block 7 assembled at the connecting end, when the connecting end 14 moves a certain distance, the push block 7 contacts the friction ring 9 and pushes it towards the recessed layer 1 on the surface of the connecting collar 2, so that the friction ring 9 supports the sleeve body 4, and both sides are supported and fixed at the same time. At this time, the sleeve body 4 is replaced by the friction ring 9 when rotating, avoiding damage to the main body. In addition, the friction ring 9 is assembled in the inner recess of the sleeve opening. When adding lubricant, the friction ring 9 can more easily retain the lubricant in the inner recess, reducing rotational friction for a longer period of time.

[0022] In actual use, the device is first installed by connecting the connecting collar 2 and the sleeve body 4. It is then fixed by the connecting bolt structure in the middle. This connecting bolt structure can not only reduce the friction between the sleeve body 4 and the connecting collar 2, but also better preserve the lubricant, minimize damage to the surface of the shaft connector, avoid damage to the anti-corrosion surface layer 3, and increase the corrosion resistance of the transmission chain.

[0023] 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.
