Abstract

The utility model discloses a door stopper, which comprises a suction base, a sucker and a buffer plate, wherein the suction base is fixed on a wall surface, the sucker is fixed on a door, a magnet is arranged at the top of the suction base, the buffer plate with a disc structure is fixedly arranged on an end surface of the suction base, the mouth of the buffer plate faces outwards, an air inlet is arranged on the buffer plate, and an elastic sheet used for closing the air inlet by aid of elasticity is arranged on the inner wall of the buffer plate. The buffer plate arranged at the top of the suction base of the door stopper has a buffering function when the sucker collides with the buffer plate, thereby effectively protecting the suction base and other components thereof against being damaged due to heavy collision and eliminating noise. Further, the door stopper utilizing the buffer plate to replace springs and stop dogs in the prior art has simple structure, low cost and longer service life.

Description

Door-inhale

Technical field

The utility model relates to a kind of door-inhale.

Background technology

Door-inhale is installed on the bottom of wall behind the door, both can prevent that door moment of opening from breaking wall, again the door of opening wide state is under played fixation, and it can at will not touched, and after door is opened, lives by door-inhale is stable, prevents to close automatically when wind.

In the prior art, door-inhale comprises and being used for fixing at suction base on the metope and the sucker that is used for fixing on door, the top of suction base is provided with spring eye along axis, spring is installed in this spring eye, one end of spring is fixed on the bottom of spring eye, the other end and collision block are fixed, and the top of suction base is provided with magnet simultaneously.When door was opened, the sucker on the door was run into collision block, the compression spring, and spring mainly plays cushioning effect, and simultaneously magnet is the sucker sorption, thereby door is fixed.But mainly there is following deficiency in the door-inhale of said structure: one, complex structure, and the cost of manufacture height, price is expensive; Two, be metal because of sucker and collision block and spring, during collision, noise is big, damages also seriously simultaneously, and application life is short.

The utility model content

At above shortcomings part in the prior art, the utility model provide a kind of simple in structure, cost is low, noise is little, the door-inhale of long service life.

The door-inhale that the utility model provides comprises being used for fixing at suction base on the metope and the sucker that is used for fixing on door that the top of described suction base is provided with magnet; The buffer disc that also comprises disk-like structure, described buffer disc is fixedly installed on the end face of suction base, and Pan Kou is outside; Described buffer disc is provided with air inlet, and the inwall of buffer disc is provided with the flexure strip that relies on elastic force sealing air inlet.

Further, described buffer disc is a rubber disc.

The beneficial effects of the utility model are: door-inhale of the present utility model adopts and at the top of suction base buffer disc is set, buffer disc had both played cushioning effect when the sucker collision is on buffer disc, protected the remaining part on suction base and the suction base to avoid the collision of huge power and damage the while noiseless effectively; This door-inhale adopts buffer disc to replace spring of the prior art and collision block, makes that it is simple in structure, cost is low, and longer service life.

Description of drawings

Accompanying drawing is a structural representation of the present utility model.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is done to describe in further detail.

Accompanying drawing is a structural representation of the present utility model, and as shown in the figure: door-inhale comprises and being used for fixing at suction base on the metope 1 and the sucker 2 that is used for fixing on door.Suction base 1 is made up of soup stick 7, base I8, magnet 3 and buffer disc 4, base I8 is installed in behind the door wall bottom by swell fixture, the bottom rotation set of soup stick 7 is on base I8, the top of soup stick 7 is provided with the magnet mounting groove, magnet 3 is fixedly mounted in the magnet mounting groove, buffer disc 4 is fixedly mounted on the top of soup stick 7, and the opening of buffer disc 4 is outside.Sucker 2 is fixedly mounted on behind the door by base II9, and base II9 adopts screw to be installed on the door, and sucker 2 passes through the threaded engagement rotation set on base II9, and sucker 2 is corresponding with buffer disc 4 in the horizontal direction.Buffer disc 4 is a disk-like structure, is uniformly distributed along the circumference on the buffer disc 4 of disk-like structure to establish four air inlet 5 is arranged, and the inwall of buffer disc 4 is provided with the flexure strip 6 that relies on elastic force sealing air inlet 5.

In the present embodiment, buffer disc adopts rubber disc, and it is big that rubber disc has coefficient of elasticity, the advantage of good buffer effect.

When door is opened, sucker 2 on the door at first bumps on the Pan Kou of buffer disc 4, sucker 2 forms the buffer body that seals with buffer disc 4, air pressurized in the buffer body of sealing reaches good buffering effect, self also have good cushioning effect during buffer disc 4 pressurizeds, therefore, good buffer effect, opposite house and wall are protected effectively, and noise is low; Meanwhile, the magnet 3 sorption suckers 2 on the soup stick 7, the position of fixed gate, prevent the door touch.At closing time, sucker 2 forms the buffer body tension that seals with buffer disc 4, and flexure strip 6 is opened, and air enters by air inlet 5 in the buffer body of sealing, and sucker 2 breaks away from buffer discs 4, and in the present embodiment, flexure strip 6 plays a part one way valve.

Explanation is at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
