Description

Rear mounted soundproof door frame

This novel invention relates to the structure of a door frame, in particular to a rear-mounted soundproof door frame structure.

Common door frame fixing methods can be roughly divided into two types: front construction method and back construction method. The front construction method is usually used when building a house. The door frame can be fixed first and then the brick wall or cement wall can be built along the door frame. Different from the front construction method, the back construction method is more commonly used for the redecoration of an existing house. The door frame using the back construction method is also called the "back-installed door frame".

Traditional door frames are mostly made of wood. Solid wood door frames are easily affected by factors such as environmental moisture or incomplete pest control of the wood itself, which can cause door frame rot and insect infestation after construction. Another type of door frame made of recycled plywood is also easily affected by environmental moisture, which can cause the bottom of the door frame to crack and swell after construction, resulting in the door leaf being unable to close normally.

The technical problem that this new type of rear-mounted soundproof door frame aims to solve is to provide a door frame that will not cause problems such as rotting, expansion, and insect infestation, has the advantages of fast production and good sound insulation, and can be applied to walls of different thicknesses.

In order to solve the above technical problems, a preferred embodiment of the new rear-mounted soundproof door frame is composed of a combination of a transverse frame plate and a longitudinal frame plate, and the improved part is that: the structure of any of the transverse frame plates and the longitudinal frame plates includes: a main body plate and a line plate;

The main body panel comprises: a main body, a first decorative part and a first outer layer; the main body and the first decorative part are a porous structure combined into one body, the first outer layer is coated on the visible position of the main body panel, the main body and the first decorative part are made of polyvinyl chloride (PVC) foam material, the first outer layer is a polyvinyl chloride coating layer, the main body has a first inner side surface for bonding to the mounting surface of the wall, the first decorative part has a second inner side surface for bonding to the first wall surface of the wall; the main body panel has a door stop for abutting against the edge of the door leaf when the door leaf is in the closed position; the main body panel has a second fitting groove, the long axis direction of the second fitting groove is parallel to the first inner side surface;

The wire board includes: a fitting part, a second decorative part, and a second outer layer; the fitting part and the second decorative part are a porous structure combined into one body, and the second outer layer is coated on the visible position of the outer surface of the wire board; the fitting part can be slidably embedded in the second fitting groove of the main body plate, and the second decorative part has a third inner side surface for being attached to the second wall surface of the wall; the fitting part and the second decorative part are made of polyvinyl chloride foam material, and the second outer layer is a polyvinyl chloride coating layer.

As a preferred embodiment of the new rear-mounted soundproof door frame, the side of the door stop has a first engaging groove, and a buffer pad is embedded in the first engaging groove.

As a preferred embodiment of the new rear-mounted soundproof door frame, the main body is provided with a hollow inner cavity.

The advantages and functions of this new type of rear-mounted soundproof door frame include:

1. The door frame is made of PVC foam material, which will not cause door frame rot, expansion and insect infestation.

2. Because the door frame is made of PVC foam material, the physical sound insulation properties of the porous structure can effectively improve the sound insulation performance of the door frame.

3. The door frame is made of PVC foam material. During production, the co-extrusion technology can be used to form the first outer layer of the main board and the second outer layer of the line board in one piece. The production is fast, and its appearance texture and color can also be changed by veneer.

4. This new type of rear-mounted soundproof door frame is composed of a main body plate and a line plate. By adjusting the position of the line plate relative to the main body plate, it can be applied to walls of different thicknesses and has better applicability.
