Description
Technical field
The utility model relates to a kind of door-inhale, particularly a kind of door-inhale that is applicable on the metal anti-theft door.
Background technology
The effect of door-inhale is temporary transient fixed in position for the door that will open, makes it not to swing or to close because of wind or slight external force effect; Existing door-inhale generally comprises the armature component that is fixed on the door and is fixed on the metope or ground magnetic suction base composition, and door is inhaled mutually with the magnetic suction base by armature and fixed; The weak point that said structure exists has: the one, in the time of on being used for metal anti-theft door, though the magnetic suction base can be inhaled mutually with metal anti-theft door, because the magnetic suction base is not provided with elastic buffer function, burrow so still will on door, hole and armature component to be installed and the magnetic suction base matches, so not only increase the installation difficulty of door-inhale, and boring burrows and will certainly influence the intensity of security door and attractive in appearance on door; The 2nd, existing door-inhale function singleness can not it be used.For this reason, many research units, manufacturer and knowledgeable people research and develop, but so far solution are not preferably arranged as yet.
Summary of the invention
For overcoming the problems referred to above that existing door-inhale exists, the purpose of this utility model provides the door-inhale of a kind of simple and reasonable, easy for installation, adsorption reliability, wide adaptability.
The technical scheme that its technical problem that solves the utility model adopts, it comprises magnet, magnet holder, magnet is fixed on the magnet holder, be fixed with the turriform spring on the described magnet holder, the other end of turriform spring is fixed with base plate, be provided with the flexible plastic sheath that is connected as a single entity by Shooting Technique on magnet, magnet holder, turriform spring and the base plate, the clinkering of flexible plastic sheath is on the turriform spring and become one.
For ease of installing and fixing, described base plate is provided with inner bolt hole, is fixed with holder on the inner bolt hole.Described holder is provided with fixing hole.
After adopting said structure, the utility model has following characteristics: the one, during with the supporting use of metal anti-theft door, any device need be installed on the shop front, and magnet is inhaled with metal anti-theft door mutually across the flexible plastic sheath, and the shop front can be damaged; Owing between base plate and the magnet holder turriform spring and flexible plastic sheath are set, therefore turriform spring and flexible plastic sheath produce distortion and play cushioning effect when colliding, and eliminate impact force.The 2nd, when with the supporting use of timber, increase the armature component that is installed on the door and get final product.The 3rd, the utility model can also use as the door top.Have advantages such as simple and reasonable, easy to install, good reliability, the scope of application be big.
