Description

A high-strength door frame for an electric metal door

technical field

The utility model relates to the technical field of building materials, in particular to a high-strength door frame for electric metal doors.

Background technique

Door cover is a term of architectural decoration, which refers to the two door frames inside and outside the door. Its main function is to fix the door leaf and protect the corners and decorations. It is often used in the decoration process to protect the door from scratches, corrosion, Damaged, dirty, etc.

When the existing door frame is installed, the on-site decoration workers directly fix it to the wall of the door opening with nails, and smooth it with mortar and putty powder at the connection gap between the door frame and the wall. This installation method has low structural strength. When the door When the body is subjected to a strong impact from the outside, the door frame is very easy to collapse and fall off together with the door body. Therefore, we propose a high-strength door frame for electric metal doors.

As a further description of the above technical solution:

Guard plates are fixedly connected to the outside of the main body of the door frame.

As a further description of the above technical solution:

The left inner wall of the main body of the door frame is rotatably connected with a door panel through a hinge, and the right side of the middle part of the door panel is fixedly connected with a handle.

As a further description of the above technical solution:

A rubber pad is fixedly connected to the inner wall of the main body of the door frame.

As a further description of the above technical solution:

The main body of the door frame is made of aluminum alloy.

As a further description of the above technical solution:

The other end of the rotating rod is externally fixedly connected with a rubber pad.

As a further description of the above technical solution:

The left, right, upper and lower ends of the door frame main body are provided with through holes.

The utility model has the following beneficial effects:

In the utility model, the rotation of the rotating rod drives the gear and the limit ring to rotate synchronously, so that the two rack columns are separated from each other and the sliding plate is driven to move left and right, so that the fixing pin is embedded in the fixing pin installation hole on the wall, and the door frame is realized. The fastening and fixing of the door frame can effectively improve the installation strength of the door frame, making it difficult to separate from the wall.

Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

1-4, an embodiment provided by the utility model: a high-strength door frame for an electric metal door, including a door frame main body 1, the upper and lower ends of the middle part of the door frame main body 1 are provided with a card slot 2, and the card slot 2 is mainly fixed Rotating rod 3 rotates, and the middle part of each card slot 2 is connected with rotating rod 3, and rotating rod 3 mainly drives gear 4 to rotate. The middle part of rotating rod 3 is fixedly connected with gear 4, and gear 4 mainly drives gear The bar column 5 has the function of moving left and right, and the outside of the gear 4 is meshed with a rack column 5, and the rack column 5 mainly drives the sliding plate 6 to move left and right, and the left side of the rack column 5 is fixedly connected with the sliding plate 6 , the sliding plate 6 mainly drives the fixed pin 7 to move left and right and insert it into the mounting hole for fixing. The left side of the sliding plate 6 is fixedly connected with the fixed pin 7, and the bottom end of the card slot 2 is provided with a limiting groove 8, which The middle part of 8 rotates and connects the limit ring 9, and the limit ring 9 mainly fixes the rotating rod 3 for positioning and rotating. The middle part of the limit ring 9 is fixedly connected with the rotating rod 3, and the other end of the rotating rod 3 is provided with a hexagonal groove 10 , The hexagonal groove 10 is mainly inserted into the wrench to rotate.
