Detailed Description
The following detailed description of the embodiments of the utility model, given by way of example only, is presented in the accompanying drawings to aid those skilled in the art in a more complete, accurate and thorough understanding of the inventive concepts and aspects of the utility model, and to facilitate their practice.
As shown in fig. 1 and 2, in the adjustable chain dismounting device, a fixed seat 3 is connected with a chain 1, a chain wheel 2 is movably connected on the fixed seat 3, and the chain 1 is matched with the chain wheel 2; one end of the chain 1 is fixedly connected with the fixed seat 3, the other end of the chain penetrates out of the fixed seat 3, and the side end of the fixed seat 3 is fixedly connected with the handle 6.
The sprocket 2 is connected with the fixing seat 3 through the rotating shaft 7 and the clamping spring 5, so that the sprocket 2 rotates on the rotating shaft 7 through the bearing 4 and adjusts the caliber of the annular structure on the chain 1 along with the rotation of the sprocket 2, and therefore the disassembly of accessories such as oil filters, pipe fittings, valves and the like with different sizes is realized.
As shown in fig. 1 and 2, the end of the fixed seat 3 is provided with a rotating shaft 7, the middle of the sprocket 2 is provided with a bearing 4, the rotating shaft 7 passes through the bearing 4, and the sprocket 2 is rotationally connected with the rotating shaft 7.
A gap is arranged between the chain wheel 2 and the fixed seat 3, friction can not occur between the chain wheel 2 and the fixed seat, and the chain 1 can be flexibly adjusted. The friction resistance of the rotation of the rotating shaft 7 can be reduced by using the bearing 4, and the adjustment is convenient; the caliber formed by the chain 1 is regulated by the rotation of the chain wheel 2, the regulation precision is high, the regulation resistance is small, and the use process is simple and convenient.
As shown in fig. 1 and 2, the end of the chain 1 fixed to the fixing base 3 is in a ring-shaped structure to the mating part with the sprocket 2. The fixing seat 3 fixes one end of the chain 1, and the other end of the chain 1 is matched with the chain wheel 2 and penetrates out of the bottom of the chain wheel 2, so that the chain 1 can just form an annular structure, thereby adapting to the appearance of a fitting with a cylindrical structure and expanding the application range; and when the chain 1 is sleeved on the disassembled part, the chain cannot easily fall off, and the use safety is improved.
The two ends of the rotating shaft 7 penetrate out of the fixing seat 3, and the end part of the rotating shaft 7 is provided with a clamp spring 5.
