Description

Technical Field

[0001] This utility model relates to the field of chain technology, specifically to roller chains and chain drive systems. Background Technology

[0002] A roller chain is a type of chain drive used for transmitting mechanical power. It is widely used in household, industrial, and agricultural machinery, including conveyors, plotters, printing presses, automobiles, motorcycles, and bicycles. It consists of a series of short cylindrical rollers linked together and driven by a gear called a sprocket. It is a simple, reliable, and efficient power transmission device.

[0003] In the existing technology, the structural strength of roller chains is insufficient. When roller chains are subjected to large pressure, they are prone to breakage, which reduces the service life and reliability of roller chains. Therefore, we have introduced a roller chain and chain drive system. Utility Model Content

[0004] The purpose of this invention is to provide a roller chain and chain drive system, which not only facilitates the improvement of the structural strength of the roller chain, increases its service life and reliability, but also facilitates the installation and disassembly of the reinforcing structure, saving time and effort and increasing efficiency, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A roller chain includes an inner chain module, an outer chain module, and rollers. The inner and outer chain modules are arranged alternately. Each inner chain module includes two inner chain plates, with two pins between them. Each inner chain plate has inner shaft holes on both sides that mate with the pins. The two ends of the pins pass through the corresponding inner shaft holes, and the rollers are rotatably sleeved on the pins. The outer chain module includes two outer chain plates, with outer shaft holes at both ends. The two outer shaft holes are rotatably connected to the pins on the two inner chain modules, respectively. The outer chain module has a reinforcing mechanism on its exterior.

[0007] As a further embodiment of this utility model, the reinforcing mechanism includes a U-shaped plate, which is slidably disposed outside the two outer chain plates. A locking block is integrally formed in the middle of the opposite side of each of the two outer chain plates, and a locking hole is provided on the side wall of the U-shaped plate to cooperate with the locking block.

[0008] As a further embodiment of this invention, the locking block has a beveled sidewall.

[0009] As a further embodiment of this invention, the angle of the inclined plane is set to 45°.

[0010] As a further embodiment of this utility model, the lower end of the U-shaped plate is integrally formed with a bent push plate.

[0011] As a further embodiment of this invention, the U-shaped plate is configured as an elastic metal plate.

[0012] As a further embodiment of this utility model, both ends of the U-shaped plate are provided with guide grooves that cooperate with the pin shaft.

[0013] A chain drive system further includes a sprocket, which is engaged with a roller chain for transmission.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This roller chain and chain drive system, through a U-shaped plate, inner chain plate, roller, pin, push plate, locking block, guide groove, locking hole, outer chain plate, and inclined surface, directly presses the U-shaped plate downwards from the top of the two outer chain plates. The two sides of the U-shaped plate slide against the side walls of the two outer chain plates. The end of the pin slides into the guide groove. The pin and guide groove cooperate to guide the sliding direction of the U-shaped plate, ensuring that the locking block corresponds to the locking hole. The locking block pushes the two sides of the U-shaped plate to deform through the inclined surface. When the locking block corresponds to the position of the locking hole, the two sides of the U-shaped plate return to their original position, and the locking block is locked into the locking hole, completing the installation. When disassembling the reinforcing mechanism, push the two push plates to the sides. The push plates cause the two sides of the U-shaped plate to deform. When the locking block leaves the outside of the locking hole, the U-shaped plate can be removed from the roller chain. This not only facilitates the improvement of the structural strength of the roller chain, increases its service life and reliability, but also facilitates the installation and disassembly of the reinforcing structure, saving time and effort and increasing efficiency.

[0020] 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.

[0021] Please see Figures 1 to 3 This utility model provides a technical solution:

[0022] The roller chain includes an inner chain module, an outer chain module, and rollers 3. The inner chain module and the outer chain module are arranged alternately. The inner chain module includes two inner chain plates 2, and two pins 4 are provided between the two inner chain plates 2. Both sides of the inner chain plate 2 are provided with inner shaft holes that cooperate with the pins 4. The two ends of the pins 4 pass through the corresponding inner shaft holes. The rollers 3 are rotatably sleeved on the pins 4. The outer chain module includes two outer chain plates 9, and both ends of the outer chain plates 9 are provided with outer shaft holes. The two outer shaft holes are rotatably connected to the pins 4 on the two inner chain modules respectively. The outer chain module is provided with a reinforcing mechanism on its exterior.

[0023] Reference Figure 1 and Figure 2 The reinforcing mechanism includes a U-shaped plate 1, which is slidably disposed outside two outer chain plates 9. Locking blocks 6 are integrally formed in the middle of the opposite sides of the two outer chain plates 9. The side wall of the U-shaped plate 1 has locking holes 8 that cooperate with the locking blocks 6. The locking blocks 6 engage with the corresponding locking holes 8. The side wall of the locking blocks 6 has a slope 10 with an angle of 45°. The slope 10 facilitates quick installation of the U-shaped plate 1 by the operator. A bent push plate 5 is integrally formed at the lower end of the U-shaped plate 1. The push plate 5 facilitates bending both ends of the U-shaped plate 1, thus facilitating installation and disassembly. The U-shaped plate 1 is a flexible metal plate. Due to the characteristics of the flexible metal plate, the U-shaped plate 1 provides good structural rigidity for the roller chain while also facilitating the installation and disassembly of the reinforcing mechanism by the operator.

[0024] Reference Figure 1 Both ends of the U-shaped plate 1 are provided with guide grooves 7 that cooperate with the pin 4. The guide grooves 7 can provide guidance for the U-shaped plate 1 when it is installed.

[0025] A chain drive system further includes a sprocket, which is meshed with a roller chain for transmission. Rotating the sprocket can drive the roller chain.

[0026] When installing the reinforcing mechanism, press the U-shaped plate 1 directly downwards from the top of the two outer chain plates 9. The two sides of the U-shaped plate 1 are slidably connected to the side walls of the two outer chain plates 9. The end of the pin 4 slides into the guide groove 7. The pin 4 and the guide groove 7 cooperate to provide guidance for the sliding direction of the U-shaped plate 1, ensuring that the locking block 6 corresponds to the locking hole 8. The locking block 6 pushes the U-shaped plate 1 to both sides through the inclined surface 10 to deform the two sides. When the locking block 6 corresponds to the position of the locking hole 8, the two sides of the U-shaped plate 1 return to their original position, and the locking block 6 is locked into the locking hole 8. The installation is complete. When disassembling the reinforcing mechanism, push the two push plates 5 to both sides. The push plates 5 cause the U-shaped plate 1 to deform on both sides. When the locking block 6 leaves the outside of the locking hole 8, the U-shaped plate 1 can be removed from the roller chain. This not only facilitates the improvement of the structural strength of the roller chain, but also improves its service life and reliability. It also facilitates the installation and disassembly of the reinforcing structure, saving time and effort and increasing efficiency.

[0027] 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.
