Spring not prone to deformation

Abstract

The invention discloses a spring not prone to deformation. The spring comprises a support A and a support B, two telescopic rods are arranged on the right side of the support A, a pin rod is installedin the middle of the right side of the support A, a magnetic surface B is arranged outside the pin rod, telescopic sleeves are arranged at the left side of the support B, a buffer base is arranged atthe right side of the support B, an enlarging hole is formed inside the buffer base, a magnetic block A is arranged at the right end inside the enlarging hole, and the right end of the pin rod penetrates through the enlarging hole. Accordingly, by arranging four sliding blocks on the outer wall of each telescopic rod, four sliding rails are arranged on the inner side of each telescopic sleeve, when the telescopic rods and the telescopic sleeves retract, the shift phenomenon cannot occur, and it is guaranteed that the spring cannot deform when compression is conducted; due to the fact that oilholes are formed in the sliding rails, a user can inject lubricating oil into the sliding rails and sliding grooves through the oil holes in the later period, the frictional force of the sliding blocks and the sliding rails is reduced, and the spring is practical and suitable for widely application and popularization.

Description

technical field [0001] The invention relates to a spring, in particular to a spring which is not easily deformed. Background technique [0002] At present, springs are widely used. In daily life, springs are commonly used for shock absorption. When springs are used for shock absorption for a long time, the uneven force of springs will cause deformation of springs, which will affect the effect of shock absorption and contraction of the entire spring. Therefore, we propose a spring that is not easily deformed. Contents of the invention [0003] The main purpose of the present invention is to provide a spring that is not easy to deform. By setting four sets of sliders on the outer wall of the telescopic rod and four sets of slide rails on the inner wall of the telescopic sleeve, when the telescopic rod and the telescopic sleeve are contracted, there will be no Offset phenomenon occurs, so as to ensure that the spring will not deform when it is compressed. Since there are oil...
