Description

Door frame hinge

Technical Field

The utility model relates to the field of hinges, in particular to a door frame hinge.

Background

In door and window materials, the door frame aluminum profile is a part responsible for being connected with a wall body, is fixed on the wall body and cannot move. At present, when an aluminum profile door frame is installed, bolts with the door frame are often used for fixing the door frame on the inner side of a wall frame, and grouting is carried out in gaps for further fixing and sealing.

For example, chinese patent publication (publication No. CN 211422320U) discloses a door frame aluminum profile convenient for grouting, which comprises a door frame main body, wherein the door frame main body is fixedly arranged on the inner side of a wall frame through bolts, sealing sheets are arranged on the outer side of the door frame main body, decorative baffles are arranged on the front side and the rear side of the door frame main body, the sealing sheets comprise sheet bodies fixedly arranged on the front side and the rear side of the outer surface of the door frame main body, the distance between the outer surfaces of the sheet bodies on the front side and the rear side is smaller than the thickness of the door frame main body by 2 cm, grooves are formed in the outer surfaces of the sheet bodies, sealing strips are fixedly arranged in the grooves, and the left surfaces of the sealing strips are tightly attached to the inner side of the wall frame.

However, when grouting, the slurry has certain fluidity, and easily flows out from the reserved hinge part of the door frame, so that the normal use of the hinge is affected, the stress capability of the door frame is poor, the sealing performance is not strong, and the air leakage phenomenon is easy to occur.

Disclosure of Invention

The utility model provides a door frame hinge which can solve the problem that slurry flows outwards from a reserved hinge of a door frame.

In order to solve the technical problems, the application provides the following technical scheme:

the door frame hinge comprises a door frame, wherein a hinge seat is fixedly arranged on the side wall of the door frame, a housing used for isolating the hinge seat from being contacted with slurry is fixedly arranged on the outer side of the door frame, and the housing is a hollow closed body.

The basic scheme principle and the beneficial effects are as follows: because when installing aluminium alloy door frame, use the bolt from taking of door frame to fix the door frame in the wall frame inboard, grout is further fixed and sealed in the gap, and the housing sets up the one end that is close to the wall at the hinge seat, and during the grout, the thick liquid flows into the gap between the wall frame inboard and the door frame outside, and when flowing to the hinge seat height, the thick liquid drops downwards around the appearance edge of housing, can not directly contact with the hinge seat, until with all gaps filling finish.

The setting up of housing is passed through in this scheme, and the leakproofness is good, has effectively prevented thick liquid and hinge seat contact, and no thick liquid flows tight door frame inner wall through the position of installation hinge seat after having irritated thick liquid to the door frame inner wall all keeps clean and tidy around grouting, has reduced the clearance degree of difficulty in later stage.

Because the slurry is not in direct contact with the hinge seat, the hinge seat can not influence the normal use of the hinge seat after the slurry is solidified, thereby ensuring the normal function of the hinge seat and reducing the rust risk. The normal cooperation of hinge and hinge seat is used, has promoted life.

The hollow setting of the housing can enable the screw for installing the hinge to be directly inserted into the housing when the hinge is installed subsequently, so that the wall body can not be damaged without being inserted into the wall body, and the integrity of the wall body is ensured.

In conclusion, the influence of slurry on the door frame and the hinge seat is effectively avoided through the arrangement of the housing, normal use of the hinge is guaranteed, the stress capacity and the tightness of the door frame are improved, the generation of air leakage is reduced, and the problem that slurry flows outwards from the reserved hinge of the door frame is solved.

Further, the hinge seat is connected with the door frame through screws, and a plurality of hinge holes are formed in the hinge seat. Easy to install and simple in structure.

Further, the housing is fixed at one end of the hinge base near the inner side of the wall frame. The housing is hidden between the door frame and the wall frame, so that the installation of the subsequent door can not be influenced. When the hinge is installed, the screw is directly nailed into the housing, and labor is saved compared with the nailing into the wall.

Further, the wall frame further comprises a door frame reinforcing block, and the door frame reinforcing block is fixed on the door frame close to the inner side of the wall frame. The stability of the door frame is guaranteed, and the strength of the door frame is increased.

Further, seals are fixed above and below the welding reinforcing blocks. The seal is used for blocking slurry flowing out from a gap between the hinge seat and the door frame in grouting.

Further, the wall frame further comprises a welding reinforcing block, one end of the welding reinforcing block is fixed on the hinge base, and the other end of the welding reinforcing block is fixed on the door frame close to the inner side of the wall frame. The hinge seat and the housing are stabilized, the fitting degree of the hinge seat and the door frame is improved, and the hinge seat and the door frame are prevented from falling.

Further, the welding reinforcing blocks are two, and are respectively arranged at the upper end of the housing and the lower end of the housing. The cover shell is synchronously fixed on the hinge seat, so that the dislocation and falling of the cover shell are prevented.

Further, the two sides of the door frame are provided with rolling grooves. The setting of rolling up the groove, when the grout, can be better with thick liquid seal up in the gap, prevent that it from outwards spilling over on a large scale, and thick liquid firm shaping back, the rolling up the groove by solidification in the wall that thick liquid firmly formed, become a whole, increased the intensity of door frame, promoted the anti extrusion ability of door frame.

Further, the door frame near the inner side of the wall frame is provided with a step platform which is Z-shaped, the shape of the hinge seat is matched with that of the step platform, and the hinge seat is fixed on the step platform. After the door is installed, the stepped steps can improve the tightness of the door and the door frame.

Further, the door frame is integrally formed and sequentially distributed into a left side rolling groove, a Z-shaped platform and a right side rolling groove. The forming is convenient, and the processing is simple.
