Description

Technical Field

[0001] The utility model belongs to the technical field of door frame installation, and in particular relates to a supporting device for door frame installation. Background Art

[0002] In the prior art, the support device for door frame installation involves door frame installation technology. If the direction or position of the door needs to be adjusted, the movable function can provide great convenience. A door frame without the ability to move may limit the flexibility of the door operation, and after the bottom plate of the traditional device contacts the ground and the bottom door frame, the bottom plate may not be in a horizontal state due to the uneven surface of the ground or the bottom door frame, which may affect the support effect of the support plate on the door frame. At the same time, the door frame cannot ensure that the top and bottom surfaces cannot be kept horizontal, which may cause the door frame to be easily offset during installation. Finally, the door frame needs to be disassembled again, or the installed door frame needs to be broken and reinstalled, which is laborious and time-consuming, slows down work efficiency, and also causes losses and increases costs.

[0003] The existing authorization number is CN 209509942 U, which discloses a support device for door frame installation, including a wall, a door frame, a bracket, a support, a wall friction plate, a bracket stud, a support plate, a clamping seat, a clamping plate, a clamping stud, a push plate, a screw sleeve, a push rod screw, a rotating sleeve and a clamping plate. The clamping stud is rotated by rotating the handle to press the front end of the clamping stud against the back of the wall, so that the bracket is fixed to the wall through the wall friction plate and the clamping plate. The bracket stud is rotated by the handle to lift the door frame upward, so that the top of the crossbeam of the door frame is in close contact with the top of the side wall of the wall door opening, the push plate is clamped on the wall, and the push rod screw is rotated to move the screw sleeve outward along the push rod screw, so that the push plate and the bottom of the inner part of the door frame are pressed against the side wall of the door opening of the wall, so that the door frame is fixed in the door opening of the wall, which is convenient for installation.

[0004] However, the flexibility of the above-mentioned support device for door frame installation is poor. After the bottom plate contacts the ground and the bottom door frame, the bottom plate may not be in a horizontal state due to the uneven surface of the ground or the bottom door frame, and additional tools are required for adjustment. In addition, when the bottom of the device is not convenient to move, the flexibility of door operation is limited. At the same time, the device fixes the top of the door frame by clamping it on the wall and fixing it by friction, which has high requirements for the working environment and the wall, and cannot ensure that the top and bottom surfaces are level, and has high technical requirements for workers. Therefore, it is necessary to propose a support device for door frame installation to solve the above problems. Utility Model Content
