Abstract
The utility model relates to daily articles, in particular to an automatic chain adjustment wheel which mainly overcomes defects existing in the prior art. The automatic chain adjustment wheel comprises an adjustment wheel body, and is characterized in that the adjustment wheel body is made of a rod, one end of the adjustment wheel body is connected with an idler wheel, the other end of the adjustment wheel body is provided with a small hole, and the middle section of the adjustment wheel body is provided with a spring. The automatic chain adjustment wheel is simple in structure and convenient to use. What is needed is to fix the automatic chain adjustment wheel onto a vehicle frame through the small hole, the idler wheel abuts against a chain through pressure of the spring, so when the chain is elongated due to abrasion, the idler wheel can still keep elastic effects of the chain through the pressure of the spring.
Description
Technical field
The utility model relates to a kind of daily living article, especially relates to the automatic adjusting knurl of a kind of chain.
Background technology
Motor bike and bicycle all are to adopt chain gear, use the structure of chain gear when long-time the use, and chain will wear and tear, and causes chain lax, thereby influences the reliability of chain gear.
Summary of the invention
The purpose of this utility model provides the automatic adjusting knurl of a kind of chain, and it mainly solves the characteristics that there is weak point in existing technology.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals.
The automatic adjusting knurl of a kind of chain of the present utility model, comprise an adjusting knurl 1, it is characterized in that described adjusting knurl 1 made by a pole, be connected with a roller 2 at an end of adjusting knurl 1, the other end is provided with an aperture 3, and is provided with spring 4 in the stage casing of adjusting knurl 1.
The utlity model has simple in structure, easy to use, as long as people are fixed on the aperture on the automatic chain adjusting knurl on the vehicle frame, roller withstands on the chain by the pressure of spring, so just guaranteed chain when wearing and tearing are elongated, roller still can make chain keep the degree of tightness effect by the pressure of spring.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model.
The specific embodiment
Below by embodiment, and by reference to the accompanying drawings the technical solution of the utility model is described in further detail.
Embodiment, as shown in Figure 1, the automatic adjusting knurl of a kind of chain of this example, comprise an adjusting knurl 1, it is characterized in that described adjusting knurl 1 made by a pole, be connected with a roller 2 at an end of adjusting knurl 1, the other end is provided with an aperture 3, and is provided with spring 4 in the stage casing of adjusting knurl 1.
During use, as long as people are fixed on the aperture on the automatic chain adjusting knurl on the vehicle frame be, roller withstands on the chain by the pressure of spring, has so just guaranteed chain when wearing and tearing are elongated, and roller still can make chain keep the degree of tightness effect by the pressure of spring.
