Description

Technical Field

[0001] This utility model relates to the field of guide rail technology, specifically to a guide rail with good corrosion resistance. Background Technology

[0002] A guide rail is a groove or ridge made of metal or other materials that supports, fixes, guides, and reduces friction of moving devices or equipment. Guide rails can be used to guide motorcycle chains. However, existing guide rails still have certain defects in use.

[0003] According to a publicized guide rail with good corrosion resistance (publication number: CN220566518U), the U-shaped seat is made of iron-based alloy. Iron-based alloy has good corrosion resistance and can effectively resist the corrosion of rainwater. After long-term use, debris will accumulate at the bottom of the chain, and manual cleaning is time-consuming. At this time, a cleaning brush can be pulled to move it. When the cleaning brush moves, it can drive the guide rod to move. When the guide rod moves, it can slide through the connecting block. When the foam block moves to the inner wall of the U-shaped seat, it can generate compression deformation. At this time, it can significantly reduce the noise generated by the sliding of the slide. It is convenient for the guide rail to reduce the noise generated by the slide through the noise reduction plate and the foam block during use.

[0004] During use, the cleaning brush needs to be manually adjusted to fit the chain, and it is not easy to replace the cleaning brush after it wears out. The chain will also be corroded by rainwater, resulting in corrosion and rust, which will cause wear when it comes into contact with the guide rail. Utility Model Content

[0005] The purpose of this invention is to provide a guide rail with good corrosion resistance to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a guide rail with good corrosion resistance, comprising a guide rail body, wherein multiple sets of arrayed rollers are rotatably connected between the guide rail bodies, a cleaning component is provided inside the guide rail body, and an oiling component is provided on the side wall of the guide rail body. The cleaning component includes a telescopic rod, which is fixedly connected to the inner wall of the guide rail body. A top plate is fixedly connected to the top of the telescopic rod, and the top plate is elastically connected to the inner wall of the guide rail body by a return spring. A sponge pad is attached to the surface of the top plate.

[0007] Preferably, the oil filling assembly includes an oil tank, a hose is fixedly connected to the side wall of the oil tank, the hose passes through and is fixedly connected to the bottom surface of the top plate, a cotton thread is provided inside the hose, one end of the cotton thread extends into the inside of the oil tank, and the other end of the cotton thread is inserted into the inside of the sponge pad.

[0008] Preferably, four sets of positioning strips are fixedly connected to the surface of the top plate, and the four sets of positioning strips are respectively attached to the perimeter of the sponge pad.

[0009] Preferably, the return spring is sleeved on the outer wall of the telescopic rod.

[0010] Preferably, the surface of the oil tank is provided with an oil filling port, and the top of the oil filling port is provided with a cap.

[0011] Preferably, a limiting ring is fixedly connected to the outer wall of the cotton thread, and the limiting ring is in contact with the surface of the top plate.

[0012] Compared with the prior art, this utility model provides a guide rail with good corrosion resistance, and has the following beneficial effects:

[0013] 1. This corrosion-resistant guide rail, with its return spring and telescopic rod working together in the cleaning assembly, allows the top plate to automatically conform to the chain, ensuring the stability of cleaning and oiling effects. The positioning strip prevents the sponge pad from shifting, and the sponge pad can be easily replaced by pressing the top plate, making operation simple.

[0014] 2. This corrosion-resistant guide rail features an oiling component that continuously supplies oil to the sponge pad via the capillary action of cotton threads. This ensures that the lubricating oil is evenly applied to the chain surface, forming a protective film that effectively isolates corrosive media such as moisture and oxygen, thereby improving the chain's corrosion resistance and extending its overall service life.

[0019] like Figures 1-3As shown, this utility model provides a technical solution: a guide rail with good corrosion resistance, comprising a guide rail body 1, with multiple sets of arrayed rollers 2 rotatably connected between the guide rail bodies 1. The guide rail bodies 1 are disposed on the bottom surface of a chain, and the rollers 2 are in contact with the bottom surface of the chain, serving as support and guidance. A cleaning component 3 is disposed inside the guide rail body 1, and the cleaning component 3 is located in the gap between two sets of rollers 2.

[0020] The cleaning component 3 includes a telescopic rod 31, which is fixedly connected to the inner wall of the guide rail body 1. A top plate 32 is fixedly connected to the top of the telescopic rod 31. The telescopic rod 31 guides the top plate 32 vertically, allowing it to move up and down. The top plate 32 is elastically connected to the inner wall of the guide rail body 1 via a return spring 33, which is sleeved on the outer wall of the telescopic rod 31. The return spring 33 provides support for the top plate 32, causing it to move upwards towards the bottom of the chain. A sponge pad 34 is attached to the surface of the top plate 32. The sponge pad 34 adheres tightly to the chain, absorbing and cleaning dust and debris during chain transmission. Four sets of positioning strips 35 are fixedly connected to the surface of the top plate 32, each set fitting around the perimeter of the sponge pad 34. These positioning strips 35 position the sponge pad 34, preventing it from shifting during compression. At the same time, the top plate 32 moves downward, compressing the return spring 33, so that the sponge pad 34 is away from the bottom surface of the chain, making it easier to remove the sponge pad 34 for replacement.

[0021] The side wall of the guide rail body 1 is equipped with an oil injection assembly 4, which includes an oil tank 41. A flexible hose 42 is fixedly connected to the side wall of the oil tank 41. The flexible hose 42 passes through and is fixedly connected to the bottom surface of the top plate 32. A cotton thread 43 is installed inside the flexible hose 42. One end of the cotton thread 43 extends into the oil tank 41, and the other end is inserted into the sponge pad 34. The oil tank 41 contains lubricating oil, which is delivered to the sponge pad 34 through the capillary action of the cotton thread 43, keeping it moist. The flexible hose 42 protects the cotton thread 43 and does not interfere with the movement of the top plate 32. When the sponge pad 34 comes into contact with the chain, the lubricating oil is evenly coated on the chain surface, isolating it from moisture, oxygen, and corrosive media in the air, thus delaying the corrosion of the chain.

[0022] A limiting ring 44 is fixedly connected to the outer wall of the cotton thread 43. The limiting ring 44 fits against the surface of the top plate 32, allowing the cotton thread 43 to move with the top plate 32, preventing the cotton thread 43 from falling off and ensuring stable oil supply. The surface of the oil tank 41 is provided with an oil inlet 45, and the top of the oil inlet 45 is provided with a cap 46. Lubricating oil can be replenished at any time through the oil inlet 45, while the cap 46 prevents lubricating oil contamination or evaporation.

[0023] In this invention, during use, the bottom surface of the chain is in contact with the roller 2 on the guide rail body 1 during transmission. The roller 2 rotates with the movement of the chain, providing stable support and guidance for the chain and reducing frictional resistance during chain transmission.

[0024] Simultaneously, supported by the return spring 33, the top plate 32 moves the sponge pad 34 upward, ensuring it fits tightly against the bottom surface of the chain. As the chain drives forward, the sponge pad 34 continuously wipes the bottom surface of the chain, using its own adsorption capacity to clean dust and debris, keeping the chain clean. During this process, four sets of positioning strips 35 tightly adhere to the perimeter of the sponge pad 34, effectively preventing displacement of the sponge pad 34 under the pressure and friction of the chain, ensuring the stability of the cleaning effect.

[0025] The lubricating oil in the oil tank 41 is continuously delivered to the sponge pad 34 through the capillary action of the cotton thread 43 and the hose 42, keeping the sponge pad 34 constantly wet. When the lubricated sponge pad 34 comes into contact with the chain, the lubricating oil is evenly coated on the chain surface, forming a protective film. This not only reduces frictional wear between the chain and the roller 2 but also isolates moisture, oxygen, and other corrosive media in the air, delaying chain corrosion and enhancing its corrosion resistance. The hose 42 protects the cotton thread 43 without interfering with the lifting and lowering movement of the top plate 32; the limiting ring 44 moves synchronously with the top plate 32, preventing the cotton thread 43 from falling off during the movement of the top plate 32 and ensuring the stability of the lubricating oil delivery.

[0026] When the sponge pad 34 needs to be replaced, simply press down on the top plate 32 to compress the return spring 33, moving the sponge pad 34 away from the bottom of the chain. The old sponge pad 34 can then be easily removed. After replacing it with a new sponge pad 34, release the top plate 32. The return spring 33 will return to its original position, pushing the top plate 32 and the new sponge pad 34 upwards, re-adhering them to the bottom of the chain. If the lubricating oil in the oil tank 41 is insufficient, open the cap 46 and add lubricating oil to the tank 41 through the oil inlet 45. After adding oil, close the cap 46 to prevent lubricating oil contamination or evaporation.

[0027] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
