Abstract
The invention relates to a door-retaining device. The door-retaining device comprises a magnet. The door-retaining device is structurally characterized in that the magnet is arranged on the bottom end surface of a door leaf; the door leaf is provided with a groove in the ground corresponding to the position of the magnet after the door leaf is opened; a suction block which can stretch out of the groove and is sucked on the magnet is hinged in the groove by a connecting rod; the suction block comprises a plastic base and a plurality of iron posts arranged on the plastic base; the bottom end surface of the magnetic is provided with a plurality of iron post grooves which are respectively adaptive to each iron post; the connecting rod is in a shape of an upwards bumped bent arc; one end of the connecting rod is fixedly connected with the suction block, and the other end of the connecting rod is arranged in the groove by a pin shaft; the top ends of the iron posts are hemispheric; and three to five iron posts are uniformly arranged on the plastic base. The door-retaining device provided by the invention is firmly sucked, can be separated with little force, does not occupy space and does not have potential safety hazards.
Description
Technical field
The present invention relates to a kind of gear door gear.
Background technology
The gear door gear that uses at present mostly is greatly in the door leaf side magnet is installed, and the body of wall of magnet correspondence position arranges iron prop when opening with door leaf, can keep the opening of door leaf behind magnet and the iron prop dependence magnetic attraction.In actual use, there is following shortcoming in the gear door gear of this kind structure: 1) the suction-combining force of magnet and iron prop is often larger, and for children and old man, very effort also might be fallen by rolling at closing time, causes potential safety hazard; 2) iron prop is arranged on the metope behind the door leaf, and outstanding body of wall can stop also when it has taken too much space that the pedestrian walks.
Summary of the invention
The technical problem to be solved in the present invention provide a kind of adhesive firmly, separate laborsavingly, and do not have the gear door gear of potential safety hazard.
For solving the problems of the technologies described above, gear door gear of the present invention, comprise magnet, its design feature is that described magnet is installed on the bottom face of door leaf, the ground corresponding with the position of magnet offers groove after door leaf is opened, and groove is interior to be hinged with extended groove and to be pull-in on adhesive piece on the magnet by connecting rod.
Described adhesive piece comprises plastic feet and is installed in a plurality of iron props on the plastic feet, offers a plurality of iron prop grooves that adapt with each iron prop respectively on the bottom face of described magnet.
Described connecting rod is to curved arc shape and the one end of upper process and the adhesive piece is affixed, the other end is installed in the groove by bearing pin.
The top of described iron prop is hemispherical.
Described iron prop evenly arranges three to five on plastic feet.
The invention has the beneficial effects as follows: when door leaf is in closed condition, connecting rod and adhesive piece can drop in the groove owing to gravity, after door leaf is opened, magnet and adhesive piece approach and are pulled together, at this moment, one end of connecting rod is also taken away out groove, and door leaf has just been fixed by the magnet of mutually adhesive and adhesive piece and connecting rod like this; When needs are closed door leaf, with pin connecting rod is stepped on back in the groove, under the drive of connecting rod, magnet separates with the adhesive piece, and door leaf breaks away from fixing, and free to rotate, door leaf cuts out.As seen, only need tramp with one's feet at closing time and step on connecting rod, magnet is separated with the adhesive piece, simple to operate, laborsaving, old man or child all can easily finish, and can not shaken magnet and separating suddenly of adhesive piece and arrive; The design of iron prop and iron prop groove is so that adhesive is more firm; Connecting rod is the curved arc shape, adds the part that major connector stretches out groove, the more convenient connecting rod of trampling; Hemispherical is adopted on the iron prop top, so that more easily enter the iron prop groove during adhesive, can too clearly not be stuck in below the door leaf because of its corner angle.To sum up, gear door gear of the present invention adhesive firmly, separate laborsavingly, do not take up room and can not stay potential safety hazard.
Description of drawings
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail:
The structural representation that Fig. 1 is the present invention when magnet and adhesive piece are in attracting state;
The structural representation that Fig. 2 is the present invention when magnet and adhesive piece are in released state.
The specific embodiment
See figures.1.and.2, a kind of embodiment of gear door gear of the present invention is for comprising magnet 1, wherein, magnet 1 is installed on the bottom face of door leaf 2, the ground corresponding with the position of magnet 1 offers groove 3 after door leaf 2 is opened, and groove 3 is interior to be hinged with extended groove 3 and to be pull-in on adhesive piece 5 on the magnet 1 by connecting rod 4.As shown in Figure 2, when door leaf 2 was in closed condition, connecting rod and adhesive piece can drop in the groove owing to gravity.As shown in Figure 1, after door leaf 2 was opened, magnet 1 approached with adhesive piece 5 and is pulled together, and at this moment, an end of connecting rod 4 is also taken away out groove 3, and door leaf 2 has just been fixed by the magnet 1 of mutual adhesive and adhesive piece 5 and connecting rod 4 like this; When needs are closed door leaf 2, with pin connecting rod 4 is stepped on back in the groove 3, under the drive of connecting rod 4, magnet 1 separates with adhesive piece 5, and door leaf 2 breaks away from fixing, and free to rotate, door leaf 2 cuts out.As seen, only need tramp with one's feet at closing time and step on connecting rod 4, magnet 1 is separated with adhesive piece 5, simple to operate, laborsaving, old man or child all can easily finish, and can not shaken magnet 1 and separating suddenly of adhesive piece 5 and arrive
See figures.1.and.2, adhesive piece 5 comprises plastic feet 51 and is installed in a plurality of iron props 52 on the plastic feet 51, offers a plurality of iron prop grooves 10 that adapt with each iron prop 52 respectively on the bottom face of magnet 1.Gravity when alleviating adhesive, base and connecting rod 4 all can adopt light material to make, such as plastics etc.In addition, the number of iron prop 52 is preferably three to five, and for the iron prop 52 of being more convenient for can more successfully enter in attracting process in the iron prop groove 10, hemispherical is adopted on the top of iron prop 52.
See figures.1.and.2, expose more groove 3 in order to make connecting rod 4 when the adhesive, connecting rod 4 is the curved arc shape to upper process.One end of connecting rod 4 and adhesive piece are 5 affixed, the other end is installed in the groove 3 by bearing pin 6.
In sum, the invention is not restricted to the above-mentioned specific embodiment.Those skilled in the art under the premise without departing from the spirit and scope of the present invention, can do some changes and modification.Protection scope of the present invention should be as the criterion with claim of the present invention.
