Detailed Description

For further explanation of the embodiments, the drawings are provided as part of the disclosure and serve primarily to illustrate the embodiments and, together with the description, to explain the principles of operation of the embodiments, and to provide further explanation of the invention and advantages thereof, it will be understood by those skilled in the art that various other embodiments and advantages of the invention are possible, and that elements in the drawings are not to scale and that like reference numerals are generally used to designate like elements.

According to the utility model discloses an embodiment provides a good spring buffer of stability.

The first embodiment is as follows:

as shown in fig. 1-2, a spring damper with good stability comprises a cylinder body 1, and a damping spring 2 and a piston damping rod 3 inserted into the cylinder body 1, wherein sliding grooves 4 are formed on the left side and the right side of the cylinder body 1, a fixed rod 5 is fixedly connected in the sliding grooves 4, a spring 6 and a sliding sleeve 7 are sequentially sleeved on the fixed rod 5 from bottom to top, a limiting block 8 is fixedly connected on the outer side wall of the sliding sleeve 7, a stabilizing cover 9 with a cylindrical structure is fixedly sleeved on the piston damping rod 3, the bottom of the stabilizing cover 9 is sleeved on the cylinder body 1, limiting slots 10 are formed on the left side and the right side of the bottom in the stabilizing cover 9, and a limiting block 8 is inserted into the limiting slots 10;

example two:

the top end of the piston damping rod 3 is fixedly connected with a mounting frame 11;

the bottom of the cylinder body 1 is provided with a mounting base;

one end of the spring 6 is fixedly connected to the inner bottom surface of the sliding chute 4, and the other end of the spring is fixedly connected to the bottom surface of the sliding sleeve 7;

the length of the limiting slot 10 is greater than the height of the limiting block 8;

the height of the limiting block 8 is equal to the length of the sliding sleeve 7;

the utility model discloses a theory of operation:
