Abstract

The utility model relates to a drawer guide-rail damper. A piston rod is arranged in a cylinder body of the damper; one end of the piston rod is connected with a piston arranged in the cylinder body of the damper, and the other end thereof extends out toward one end that is opposite to the closing end of the cylinder body of the damper; viscous damping fluid is filled in the cylinder body of the damper; a plurality of overflow notches are pre-arranged on the periphery where the piston is matched with the inner wall of the cylinder body of the damper; a flexible glue sealing bat is arranged onthe piston; the tail end of the piston is provided with a bottom cover; a plurality of overflow grooves are arranged on the cover surface of the bottom cover toward one side of the flexible glue sealing bat; the tail of the closing end of the cylinder body is encapsulated with a fluid storage sponge by a sealing cover; and a plurality of overflow notches are pre-arranged on the periphery of the sealing cover. When a drawer is pulled out, the combined action of the overflow notches of the piston, the overflow notches on the sealing cover and the overflow grooves on the bottom cover can be realized to ensure the quick flowing of the damping fluid, so as to facilitate the user to pull the drawer with less labor quickly; compared with the prior art, the structure is more reasonable.

Description

A kind of drawer guideway damper

Technical field:

The utility model relates to the drawer fitting technical field, refers in particular to a kind of drawer guideway damper.

Background technology:

The drawer of prior art, in order to realize self-off function, the designer tends to install additional the snubber of band damper on slide rail, utilize the hydraulic pressure of damper to realize closing automatically of drawer, but existing damper is owing to structural shortcoming, and the damping of damper is bigger, makes when drawer is pulled out, need relatively large power just can pull out, brought inconvenience to the user.

Summary of the invention:

The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of rational in infrastructure, easy to use, pull out drawer guideway damper smoothly.

For achieving the above object, the technical scheme that the utility model provides is: a kind of drawer guideway damper, include the damper cylinder body, in the damper cylinder body piston rod is housed, one end of piston rod is connected with the piston that is positioned at the damper cylinder body, the other end of piston rod stretches out towards the opposite end of the cylinder body blind end of described damper cylinder body, be filled with viscous damping liquid in the damper cylinder body, be reserved with a plurality of overflow breach on piston and the circumference that the damper inboard wall of cylinder block matches, the flexible glue sealing is housed on the piston claps, the end of piston is installed bottom, this bottom offers a plurality of bypass channels on the capping of the side that the flexible glue sealing is clapped, the end at the cylinder body blind end is packaged with the liquid storage sponge by capping, is reserved with a plurality of overflow breach on the circumference of capping.

A plurality of overflow breach on the described piston are evenly to distribute.

A plurality of overflow breach in the described capping are evenly to distribute.

Bypass channel on the described bottom is evenly to distribute.

After adopting technique scheme, a plurality of overflow breach in piston overflow breach, the capping and the bypass channel on the bottom are when drawer is pulled out, and acting in conjunction has guaranteed flowing rapidly of damping fluid, thus make things convenient for the user laborsaving, promptly spur drawer, be compared with the prior art, structure is more reasonable.

Description of drawings:

Fig. 1 is the utility model structure sectional view.

Fig. 2 is a piston plane structure schematic diagram.

Fig. 3 seals the face structural representation of clapping for flexible glue.

Fig. 4 is a bottom plane structure schematic diagram.

Fig. 5 is a capping plane structure schematic diagram.

The specific embodiment:

Below in conjunction with accompanying drawing the utility model is described further, see that accompanying drawing 1-is shown in Figure 5, present embodiment includes the damper cylinder body 1 of open circles column type, one piston rod 2 is housed in the damper cylinder body 1, one end of this piston rod 2 is connected with the piston 3 that is positioned at the damper cylinder body, the other end of piston rod 2 stretches out towards the opposite end of the cylinder body blind end of described damper cylinder body 1, be filled with viscous damping liquid in the damper cylinder body 1, evenly distribute on piston 3 and the circumference that damper cylinder body 1 inwall matches and be reserved with a plurality of overflow breach 5 (referring to Fig. 2), the flexible glue sealing is housed on the piston 3 claps 6 (referring to Fig. 3), the end of piston is installed bottom 7, this bottom 7 evenly is distributed on the capping of a side of flexible glue sealing bat 6 and is provided with a plurality of bypass channels 9 (referring to Fig. 4), the end at the cylinder body blind end is packaged with liquid storage sponge 4 by capping 8, and evenly distributing on the circumference of capping 8 is reserved with a plurality of overflow breach 7 (referring to Fig. 5).

The embodiment of the above is preferred embodiment of the present utility model only, is not to limit practical range of the present utility model with this, so the equivalence that all shapes according to the utility model, structure and principle are done changes, all should be covered by in the protection domain of the present utility model.
