Abstract
The utility model relates to a buffering formula base knob, including the cylinder of locating the stiff end with locate the elastic piston in the cylinder, its characterized in that, the end that stretches out in the cylinder body of elastic piston is the base knob contact, be equipped with the reset spring who acts on elastic piston in the cylinder body, last one-way admission valve that is equipped with the air inlet and links to each other with cylinder front side cavity towards cylinder rear side gas outlet that is equipped with of elastic piston. The utility model discloses not only can effectively reduce the door body and bump the effort between the time of opening with the door, reduce the noise that sends because of the contact, this door knob can also be adorned at the door frame lateral part moreover, reduces the impact of the door body and door frame when closing the door through the cushioning effect, and simple structure, convenient to use, safe and reliable have great popularization and application and worth simultaneously.
Description
Technical field
The utility model relates to a kind of buffer-type door knob, and this utility model can cushion by the opposite house body under the two states that opens the door and close the door.
Background technology
At present, the door knob of selling on the market is of a great variety, of all kinds, have the magnetic gate of suction to bump, snap ring door knob or the like is arranged, these door knobs generally speaking all have an effect, stay open state at the relief door that opens the door exactly, but the major defect that these door knobs exist is: (1) is opened when contacting with door knob at door and is not had buffering, so not only causes the door knob rapid wear easily, and noise is bigger when opening the door; (2) these door knobs are not because of existing cushioning effect, so the situation that can not be applied to close the door.
Summary of the invention
The purpose of this utility model is to provide a kind of buffer-type door knob, this door knob simple structure, and good buffer effect, two kinds of situations can be used for opening the door, close the door.
The utility model is to constitute like this: comprise the cylinder of being located at fixed end and be located at the interior elastic piston of cylinder, it is characterized in that, the external part that stretches out in cylinder block of described elastic piston is the door knob contact, be provided with the back-moving spring that acts on elastic piston in the described cylinder block, described elastic piston is provided with the breather cheek valve that air inlet port links to each other with piston front side cavity towards piston rear side cavity gas outlet.
Remarkable advantage of the present utility model: by the cushioning effect of air in the cylinder and back-moving spring, reduced when door is opened effectively and the active force between the door knob, reduced the noise that sends because of collision; This door knob also can be installed in the doorframe sidepiece, by cushioning effect, reduces the impact of Men Tiyu doorframe at closing time, and is simultaneously simple in structure, easy to use.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Description of drawings
Fig. 1 is an organigram of the present utility model.
The specific embodiment
The utility model comprises the cylinder 1 of being located at fixed end and is located at the interior elastic piston 2 of cylinder, it is characterized in that, the external part that stretches out in cylinder 1 body of described elastic piston 2 is a door knob contact 3, be provided with the back-moving spring 4 that acts on elastic piston 2 in described cylinder 1 body, described elastic piston 2 is provided with the breather cheek valve that air inlet port links to each other with piston 2 front side cavitys towards piston 2 rear side cavity gas outlets, has air duct 6 in the body of the piston rod 5 of described elastic piston 2, air duct 6 rear side ports are towards the rear side cavity of piston 2, the sidewall of described air duct 6 is provided with by-pass flow pore 7, described breather cheek valve is located in the air duct 6 of by-pass flow pore 7 front sides, and described breather cheek valve constitutes by being located at the venthole 7 on air duct 6 sidewalls and being located at the elasticity sliding pin 9 that opens and closes in order to control venthole 8 on air duct 6 sidewalls.
In the work, opposite house touched 3 pressure when Yin Men opened, make piston rod 5 drive elastic pistons 2 to the rear side cavity of cylinder 1 move and pressed home spring 4 and chamber in air, at this moment, because both sides cavity inner air pressure imbalance in the cylinder 1, air promotes elasticity sliding pin 9 through air duct 6 and crosses venthole 8 in the rear side cavity, by by-pass flow pore 7 and venthole 8 to front side cavity discharged air (door knob of this moment will produce cushioning effect to the door body that clashes into it), under the effect of spring 10, after the pressure differential of both sides cavity reduced, elasticity sliding pin 9 was closed venthole 8 again; After the ambient pressure disappearance that the door body produces, under the effect of back-moving spring 4, elastic piston 2 slowly resets, and air slowly enters the rear side cavity by by-pass flow pore 7 through air duct 6 in the cavity of front side, thereby realizes the cushioning effect of door knob.
Claims (2)
