Abstract

The utility model relates to the technical field of door frame and hinge mounting structures, in particular to a hinge fixing plate and a door frame mounting structure thereof.

Description

Hinge fixed plate and mounting door frame structure thereof

Technical Field

Background

At present, many door frames are made of stainless steel plates, hinges are directly fixed on the door frames through screws, and due to the fact that the weight of the door is heavier, after the door is used for a long time, deformation can occur at the joint of the door frames and the hinges under the action of the weight of the door, namely the plates of the door frames can protrude outwards, normal opening and closing of the door can be affected when the plates of the door frames are severe, and therefore the service life of the door frames can be affected by the installation structure of the door frames and the hinges.

In order to solve the problems, the hinge fixing plate and the door frame mounting structure thereof adopt the following technical scheme:

the utility model provides a hinge fixed plate, includes the bottom plate, the border portion of bottom plate has the spacing end plate that sets up perpendicularly, is provided with the spacing curb plate of being connected perpendicularly with spacing end plate respectively in the both sides of bottom plate, be equipped with L type bayonet socket on the spacing curb plate, set up on the bottom plate and be used for the first mounting hole of door frame connection and be used for with hinge connection's second mounting hole.

The door frame structure for installing the hinge fixing plate comprises a first side plate and a second side plate which are perpendicular to each other, wherein an installation through groove is formed in the bent edge of the first side plate and the bent edge of the second side plate, one side of the installation through groove extends to a limit step from the bent edge to the first side plate, the other side of the installation through groove extends to the second side plate from the bent edge and is provided with a bearing plate, and the bearing plate is perpendicular to the second side plate; when the hinge fixed plate is inserted into the mounting through groove, the bottom plate is positioned at the back of the bearing plate, the limiting side plate is positioned at the side part of the mounting through groove, and the limiting end plate is in contact with the back of the limiting step.

Further, a third mounting hole corresponding to the first mounting hole is formed in the step surface of the limiting step, and the step surface of the limiting step is connected with the hinge fixing plate through a jacking bolt.

The beneficial effects of the utility model are as follows:

1. the hinge fixing plate is matched with the structure of the mounting door frame, the contact surface between the door frame and the hinge fixing plate is increased through the bearing plate and the step surface, so that the tensile force from the door plate borne by the door frame is shared, the stress concentration is avoided, the door frame is protected, and the service life of the door frame is prolonged.

Detailed Description

In order to make the technical purpose, technical scheme and beneficial effect of the present utility model more clear, the technical scheme of the present utility model is further described below with reference to the accompanying drawings and specific embodiments.

Example 1: the utility model provides a hinge fixed plate, as shown in fig. 1-5, includes bottom plate 1, and the border portion of bottom plate 1 has spacing end plate 2 that set up perpendicularly, is provided with spacing curb plate 3 that is connected perpendicularly with spacing end plate 2 respectively in the both sides of bottom plate 1, and bottom plate 1, spacing end plate 2 and spacing curb plate 3 adopt integrated into one piece compression molding. An L-shaped bayonet 4 is arranged on the limiting side plate 3 and is used for being clamped on a mounting through groove 10 of the door frame. A first mounting hole 5 for connecting with a door frame and a second mounting hole 6 for connecting with a hinge are formed on the bottom plate 1.

A door frame structure for installing hinge fixed plate, including mutually perpendicular's first sideboard 7 and second sideboard 8, the opposite side of first sideboard 7 has spacing step 11, and first sideboard 7, second sideboard 8 and spacing step 11 adopt integrative compression moulding. The bending edges 9 of the first side plate 7 and the second side plate 8 are dug with mounting through grooves 10, one sides of the mounting through grooves 10 extend from the bending edges to the first side plate 7 to the limiting steps 11, the other sides of the mounting through grooves 10 extend from the bending edges 9 to the second side plate 8 and are provided with bearing plates 12, and the bearing plates 12 are perpendicular to the second side plate 8.

The hinge fixed plate inserts installation through groove 10 from the back of spacing step 11, and after the hinge fixed plate inserted installation through groove 10, the bottom plate 1 of hinge fixed plate was located the back of supporting board 12, and the spacing curb plate 3 of hinge fixed plate is located the lateral part of installation through groove 10, and the spacing end plate 2 of hinge fixed plate contacts with the back of spacing step 11.

A third mounting hole 13 corresponding to the first mounting hole 5 is formed in the step surface of the limiting step 11, the step surface of the limiting step 11 is connected with the hinge fixing plate through a jacking bolt 14, and the jacking bolt 14 passes through the third mounting hole 13 and the first mounting hole 5 once to connect the hinge fixing plate with the door frame.

After the hinge fixing plate and the door frame are assembled, a first stress bearing surface is formed between the bottom plate 1 of the hinge fixing plate and the bearing plate 12 and used for reversely blocking downward pulling force of the door plate to the hinge fixing plate and the door frame, so that the door frame is prevented from deforming. The spacing end plate 2, spacing curb plate 3 of hinge fixed plate constitute the second stress bearing surface with spacing step 11 between the step face, spacing end plate 2, spacing curb plate 3 of hinge fixed plate form right angle shape's contact end face, can increase the area of contact of door frame and hinge fixed plate, make hinge fixed plate and door frame connection more firm on the one hand, and on the other hand great area of contact can further share the pulling force from the door plant that the door frame receives, avoids stress to concentrate on the door frame to improve the life of door frame.

Finally, what should be said is: the above embodiments are only for illustrating the technical solution of the present utility model, but the scope of the present utility model is not limited thereto, and any equivalent substitutions for the present utility model and modifications or partial substitutions without departing from the spirit and scope of the present utility model should be covered by the scope of the claims of the present utility model.
