Problems solved by technology
[0003] The outer tube of the existing plastic damper is generally made of plastic injection molding. Due to the limitation of the injection molding process, the length of the outer tube of the damper is not long, and it is easy to eccentric, which will easily cause the cylinder to explode when it is subjected to a strong impact.
[0004] The outer tube of the existing metal shell damper is formed by stamping and stretching a steel plate to form an outer tube with one end closed. Although the problem of frying the cylinder is solved, the length of the outer tube cannot be made due to the limitation of the steel plate drawing process. long

Embodiment Construction
[0028] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0029] see figure 1 , the metal casing damper, including a damper outer tube 08 made of metal with a damper piston 09 inside, the damper piston is in interference connection with one end of the damper rod 07, and the other end of the damper rod 07 passes through the damper The bracket 06, the oil seal rubber sleeve 04 of the damper extend out of the top end cover 02 of the damper, and are interference-connected with the pull rod head 01 of the damper. The outer tube 08 of the damper is cylindrical, and the front end is provided with the oil sealing rubber sleeve 04 of the damper and the top end cover 02 of the damper is respectively connected with the front end of the pull rod 07 of the damper and the outer tube 08 of the damper, and the rear end is provided with ...

The invention discloses a damper with a metal housing. The damper includes a damper outer tube of a damper piston, the damper outer tube being arranged inside the damper with the metal housing, the damper piston dividing a damper internal space filled with fluid into two chambers, the damper piston having a hole and / or a passage gap defined together with an inner wall of the damper outer tube; a damper top end cover and a damper tube bottom end cover respectively arranged at both ends of the damper outer tube; a damper support which is arranged in the damper outer tube and guides a damper pull rod; a damper pull rod connected to the damper piston, the damper pull rod passing through the damper support and extending out from the damper top end cover. The damper tube bottom end cover of the damper with the metal housing in the invention is provided with radial ribs and outer radial grooves which are used for arranging a seal ring and applying extrusion process to the damper outer tube, which solves the problem of proneness to cylinder explosion due to a larger impact force born by the damper. In addition, a slow-speed piston slide cavity and a rapid-speed piston slide cavity of the damper outer tube are connected to form a ladder shape, realizing both fast and slow cushioning strokes.
Description
technical field [0001] The invention relates to a damper, in particular to a metal shell damper. Background technique [0002] When the furniture wing is closed or the drawer is closed, it is easy to collide with the main body, make noise, and is also easy to damage each other. Therefore, a shock-relieving device, that is, a damper, is installed on the furniture. [0003] The outer tube of the existing plastic damper is generally made of plastic injection molding. Due to the limitation of the injection molding process, the length of the outer tube of the damper is not long, and it is easy to be eccentric, so that it is easy to explode the cylinder when it is subjected to a strong impact. [0004] The outer tube of the existing metal shell damper is formed by stamping and stretching a steel plate to form an outer tube with one end closed. Although the problem of frying the cylinder is solved, the length of the outer tube cannot be made due to the limitation of the steel plat...
