Abstract
The utility model discloses an exempt from to weld door frame hinge structure, including door frame body and door leaf, it has a plurality of recesses, every to open on the one side inner wall that the door frame body is close to the door leaf be fixed with the articulated slab through a plurality of fastening bolt on the recess, the articulated slab is the rectangle structure. Replace the welding with the fixed articulated slab of fastening bolt, the process is simple, and work efficiency is higher, and the operation process does not have the welding and sprays paint the pollution, and is more environmental protection, can not cause the injury to the human body, and the clearance between the door frame door leaf is less, in accidents such as conflagration, reduces the penetrability of flue gas, flame, reduces injury and loss.
Description
Technical Field
The utility model relates to a door industry field specifically is a exempt from to weld door frame hinge structure.
Background
The anti-theft door is a product required by every family, and is divided into a push-pull fence anti-theft door, a vertical hinged fence anti-theft door, a plastic relief anti-theft door, a multifunctional luxury anti-theft door and the like according to the structural characteristics. The anti-theft door is mainly divided into five types in material: steel, steel-wood structures, stainless steel, aluminum alloys and copper, all of which are characterized by their quality and performance.
At present, the door frame and the door leaf of current burglary-resisting door pass through the hinge fixed to an organic whole, and current fixed mode is hinge stationary blade of welding on the door leaf, and is fixed with the hinge through the hinge stationary blade, and this kind of process is complicated, need earlier hinge stationary blade welded fastening, then through the processing of spraying paint after polishing, influences product preparation efficiency, can produce the welding flue gas, and is harmful to the human body, and is not environmental protection, and can make the clearance between the door frame door leaf great.
Disclosure of Invention
The utility model aims to provide a: door frame and door leaf to above-mentioned current burglary-resisting door pass through the hinge fixed to an organic whole, and current fixed mode is hinge stationary blade of welding on the door leaf, and is fixed with the hinge through the hinge stationary blade, and this kind of process is complicated, need earlier with hinge stationary blade welded fastening, then through the processing of spraying paint after polishing, influences product preparation efficiency, can produce the welding flue gas, is harmful to the human body, and the environmental protection not, and can make the great problem in clearance between the door frame door leaf, the utility model provides an exempt from to weld door frame hinge structure.
The utility model adopts the technical scheme as follows:
the welding-free door frame hinge structure comprises a door frame body and a door leaf, wherein a plurality of grooves are formed in the inner wall of one side, close to the door leaf, of the door frame body, a hinged plate is fixed on each groove through a plurality of fastening bolts, and the hinged plate is of a rectangular structure.
The working principle is as follows: replace the welding with the fixed articulated slab of fastening bolt, the process is simple, and work efficiency is higher, and the operation process does not have the welding and sprays paint the pollution, and is more environmental protection, can not cause the injury to the human body, and the clearance between the door frame door leaf is less, in accidents such as conflagration, reduces the penetrability of flue gas, flame, reduces injury and loss.
Further, 2-6 grooves are formed at equal intervals.
Furthermore, the depth of each groove is 1-2 mm greater than the thickness of the hinge plate.
Further, the clearance between door frame body and door leaf is less than 1 mm.
Furthermore, 3-6 fastening bolts are fixed on each hinge plate.
To sum up, owing to adopted above-mentioned technical scheme, the beneficial effects of the utility model are that:
1. the utility model discloses a replace the welding with the fixed articulated slab of fastening bolt, the process is simple, and work efficiency is higher, and operation process does not have the welding and sprays paint the pollution, and is more environmental protection, can not cause the injury to the human body.
2. The utility model discloses an it has the recess to open on one side inner wall that the door frame body is close to the door leaf, makes the articulated slab just imbed the recess, makes the door frame door leaf more close to, and the clearance is littleer, in accidents such as conflagration, reduces the penetrability of flue gas, flame, reduces injury and loss.
Drawings
Fig. 1 is a sectional view of the hinge structure of the welding-free door frame of the present invention.
Labeled as: 1-door frame body, 101-groove, 2-hinged plate, 3-fastening bolt and 4-door leaf.
Detailed Description
All features disclosed in this specification may be combined in any combination, except features and/or steps that are mutually exclusive.
The present invention will be described in detail with reference to fig. 1.
Example 1
The structure of this embodiment, as shown in fig. 1, is a welding-free door frame hinge structure, including a door frame body 1 and a door leaf 4, a plurality of grooves 101 are opened on an inner wall of one side of the door frame body 1 close to the door leaf 4, a hinge plate 2 is fixed on each groove 101 through a plurality of fastening bolts 3, and the hinge plate 2 is a rectangular structure.
Replace the welding with the fixed articulated slab 2 of fastening bolt 3, the process is simple, and work efficiency is higher, and the operation process does not have the welding and sprays paint the pollution, and is more environmental protection, can not cause the injury to the human body, and the clearance between door frame door leaf 4 is less, in accidents such as conflagration, reduces the penetrability of flue gas, flame, reduces injury and loss.
Example 2
On the basis of embodiment 1, in this embodiment, further, 2 to 6 grooves 101 are equidistantly formed, and the plurality of hinge plates 2 can be fixed by the plurality of grooves 101, so that the connection of the door frame and the door leaf 4 is more stable.
Example 3
In this embodiment, on the basis of embodiment 2, further, the depth of each groove 101 is 1-2 mm greater than the thickness of the hinged plate 2, so as to avoid the hinged plate 2 from protruding, make the door frame and door leaf 4 closer, and reduce the gap between the door frame and door leaf 4.
Example 4
In this embodiment, based on embodiment 1, the gap between the door frame 1 and the door leaf 4 is smaller than 1mm, and the smaller gap between the door frame and the door leaf 4 reduces the penetration of smoke and flame and reduces damage and loss in accidents such as fire.
Example 5
In this embodiment, on the basis of embodiment 1, further, 3 to 6 fastening bolts 3 are fixed on each hinge plate 2, so that the hinge plates 2 are fixed to the door frame more stably.
