Description

Technical Field

[0001] The utility model relates to the technical field of shock absorbers, in particular to a shock absorber with a transparent protective cover. Background Art

[0002] Shock absorbers are widely used and come in many types. Existing shock absorbers used in baby strollers, child carriages, etc. are all simple structures, generally simple spring components, and have many defects: for example, the internal structure is complex and rough, resulting in a larger overall structure; since most of the structure is exposed, it is easy for water and sand to enter; the simple outer wrapping structure is not beautiful or practical, and the damping cannot be adjusted, etc., so improvements are needed. Utility Model Content

[0003] The technical problem to be solved by the utility model is: to provide a shock absorber with a transparent protective cover in order to overcome the deficiencies in the prior art.

[0004] The utility model solves the technical problem by adopting the following technical solution: a shock absorber with a transparent shield, comprising a body, the body comprising a mounting handle at one end and a lifting ring at the other end, a piston cylinder body being mounted on the mounting handle, a piston rod being mounted on the lifting ring, and the piston cylinder body being movably sleeved on the piston rod;

[0005] The mounting handle and the hanging ring are both provided with acrylic transparent shields that cooperate with each other, and the mounting handle and the hanging ring are both provided with slots. The transparent shield is fixed in the corresponding slots through a retaining spring, and the retaining spring is provided with an outer convex ring edge. The bottom of the transparent shield is clamped on the outer convex ring edge. A spring is provided outside the piston cylinder sleeve, and both ends of the spring are limited by the outer convex ring edges on the two retaining springs, and the transparent shield covers the spring therein.

[0006] Furthermore, the piston rod of the utility model is provided with a piston, a valve plate group and a powder metallurgy part, one side of the piston, the valve plate group and the powder metallurgy part are fastened and riveted by a nut and a nylon ring, and the other side is sealed in the piston cylinder by an aluminum profile cover. The valve plate group includes a bottom valve, a spring and three valve plates.

[0007] Furthermore, the piston rod described in the utility model is provided with a step section on one side and a threaded connection section on the other side, which facilitates the tight-fitting installation of the internal structure of the internal cylinder and the installation of the lifting ring.

[0008] Furthermore, the outer diameters of the two transparent shields on the installation handle and the lifting ring of the utility model are different, and when the shock absorber is under pressure, the two transparent shields move alternately with each other and a gap is left in between.

[0009] By adopting the above technical solution, the transparent shield plays three roles: 1. The internal operating status is visible, which is beautiful and novel; 2. Compared with the existing technology, it is waterproof and sandproof. 3. It prevents children from pinching their hands and feet.

[0010] Furthermore, the powder metallurgy part in the piston cylinder of the utility model is also provided with an "O" ring and a compression oil seal.

[0011] By adopting the above technical solution, oil leakage can be avoided.

[0012] The beneficial effects of the utility model are as follows: the shock absorber with a transparent shield of the utility model optimizes the shock absorber structure used in traditional baby strollers and child carriages. Since the new internal structure layout is more compact, the overall volume is reduced, the damping can be freely adjusted, and an acrylic transparent shield is added, not only the appearance is more beautiful, and the operating status of the internal structure can be seen (the working principle and actual use effect of the shock absorber are witnessed); it can also effectively play the role of waterproofing and sandproofing, especially preventing the baby from pressing or pinching the fingers and toes, thus achieving multiple goals at one stroke.
