Technical field

The utility model is related to door-inhale field, especially, is to be related to a kind of self-positioning door-inhale.

Background technology

Door-inhale is also commonly called as door knob, is the device that positioning is held after a kind of door leaf is opened, with prevent wind or touch door leaf and Close；Door-inhale is divided into two kinds of permanent magnetism door-inhale and electromagnetism door-inhale, and permanent magnetism door-inhale is commonly used in common door, can only control manually；Electricity Magnetic gate is smoked in the automatically controlled door window device such as fire resistant doorsets, has control and automatic control function manually concurrently；The door-inhale of general family expenses is generally Permanent magnetism door-inhale, door-inhale is often arranged on the lower edge at door leaf back, promotes door leaf manually by user so that door leaf is in door-inhale In the presence of be positioned in side close to metope, reach the effect of positioning door leaf；This door-inhale structure typically can only be by door leaf It is opened to maximum position to be positioned, when user needs to carry out house interior ventilation, and when protecting individual privacy again, now Door leaf is accomplished by fixed folding angle, can meet user's demand, and the folding position of fixation door leaf that can be stable；Typically Permanent magnetism door-inhale be all by magnetic material carry out attraction positioning, be usually constructed with position portion and magnetic force suction unit be grouped into, door The position portion of suction is generally vertically fixed on metope or ground, and such mounting means can occupy segment space, user or Child may trip injury during daily routines by the position portion of door-inhale；Permanent magnetism door-inhale after a protracted use, Because the door-inhale is positioned by magneticaction, therefore indoor metal dust can be adsorbed in the magnetic force attraction part of door-inhale, So that magnetic force weakens；Such door-inhale is due to no buffer structure, when by external force collision, meeting coup injury door-inhale structure, subtracts The service life of few door-inhale；In summary, therefore it there is defect.

Utility model content

In view of the above-mentioned problems, the purpose of this utility model is to provide a kind of vapour-pressure type self-positioning door attraction device, Neng Goutong Cross air pressure and carry out being automatically positioned for any folding angle.

The utility model solves the technical scheme that is used of technical problem：The self-positioning door attraction device of the vapour-pressure type, it is wrapped Include locating module, exhaust module and reseting module；The locating module includes designing in fixed plate and telescoping tube, the fixed plate There is fixing hole, the fixed plate is fixedly mounted on the lower edge at door leaf back；The telescoping tube uses arcuate corrugation pipe, described The inlet end sealing of telescoping tube is fixed in the fixing hole of the fixed plate, the outlet side of the telescoping tube and the exhaust module Connection；The exhaust module includes air bleeding valve, and the exhaust module is designed as being designed with flat housing, the exhaust module Air admission hole, venthole and reset hole；The position of the exhaust module correspondence locating module is fixedly mounted on wall, described The outlet side of the air admission hole of exhaust module and the telescoping tube is tightly connected；The air bleeding valve uses one-way valve structures, the row Air valve is fixedly mounted on the venthole of the exhaust module, and the inlet end of the air bleeding valve is designed in the exhaust module Design in the outside of the exhaust module portion, the outlet side of the air bleeding valve；The reseting module includes return unit and triggering top Bar, the return unit uses automatic telescopic module, and the principle of the automatic telescopic module is identical with the flexible principle of mechanical pencil, therefore It is not described in detail herein, the Position Design of the return unit is in the inside of the exhaust module, the telescopic end of the return unit Design is at the reset hole of the exhaust module；The position of the triggering push rod correspondence return unit is vertically fixed on described solid In fixed board.

Preferably, the telescopic end design magnetic material of the return unit, the tip designs of the triggering push rod have phase Sealing ring is designed with the magnetic material answered, the telescopic end of the return unit, the Position Design of the sealing ring is in the exhaust The inside of module.

Preferably, being designed with blast pipe on the air bleeding valve, the blast pipe uses Universal pipe, described blast pipe one end Sealing is fixed on the outlet side of the air bleeding valve, and the other end is directed at the outside of the telescoping tube.

Preferably, sealing ring is designed between the fixed plate and the telescoping tube, between the fixed plate and door leaf Cohesive material is designed with, the fixed plate is made using elastomeric material.

Preferably, being designed with retainer ring on the exhaust module, the retainer ring is fixed on wall using screw.

The beneficial effects of the utility model are：The self-positioning door attraction device of the vapour-pressure type, when in use user open manually The reseting module is opened, user is when promoting door leaf, because the telescoping tube uses bellows, so the telescoping tube is being squeezed Compressed in the presence of pressure so that the air inside the telescoping tube is pressed into inside the exhaust module, then passes through the row Air valve is discharged, and is in now negative pressure state inside the exhaust module, so door leaf can be positioned in any folding angle, is reached certainly The effect of dynamic positioning, while user is when promoting door leaf, the air pressure in the telescoping tube can play cushioning effect；When using When person promotes door leaf to maximum folding angle, the triggering push rod starts the return unit, because the return unit is touched with described Magnetic material is designed on hair push rod, so door leaf, which remains unchanged, is positioned in maximum folding angle；When user needs to close door leaf When, only it need to pull door leaf so that the triggering push rod is separated with the return unit, now the return unit is in contraction state, institute State the negative pressure state inside exhaust module to disappear, user being capable of normal switching-off door leaf.
