Description

Assembled combination door leaf

technical field

The utility model relates to the technical field of door leaf production, in particular to an assembled combined door leaf whose surrounding frame is quickly assembled with inner and outer panels by embedding.

Background technique

At present, the door leaf structure mainly refers to the anti-theft safety door formed by the metal door leaf panel and the inner frame composed of profiles, or similar door leaves with specific safety requirements. Usually, the front panel and rear panel of the door leaf are combined with the inner frame by welding. The welding is generally done by manual electric welding. Spray paint, etc., and fill the cavity between the front and rear panels with the required fillers, such as honeycomb paper, fire-resistant and heat-insulating materials, etc. The above-mentioned door leaf structure has at least the following deficiencies: first, because the solder joints are usually 8-20cm apart, the strength is difficult to guarantee, and the welding process will cause stress and deformation of the door leaf panel, and the presence of solder joints will damage the aesthetics of the door leaf; First, it is not conducive to large-scale production needs. Because it is manual welding, the quality of welding is difficult to fully guarantee; third, due to the poor sealing of the inner cavity of the door leaf, honeycomb paper materials can only be used as fillings. Good foaming materials require complex processes to complete; fourth, ultraviolet rays, dust, harmful gases, etc. produced by welding, grinding, spraying, transfer printing, painting and other processes pollute the environment and are not conducive to the health of operators. Advocated clean production is contrary; Fifth, the welding, grinding, transfer printing, bonding and other processes used in door leaf processing are complicated, the production efficiency is low, and the quality is unstable.

In response to the above problems, Chinese patents have disclosed many solutions, such as authorized publication or announcement number CN103696661B, named as assembled door leaf, CN102884269B, named as door frame manufacturing method and plate manufacturing method, CN103573112A, named as aluminum profile door leaf, CN103061649B, named as Inter-embedded and snap-fit door leaf structure, authorized announcement number CN2481825Y, name is aluminum profile door leaf), CN2355076Y, name is combined multi-leaf door, CN2268102Y, name is metal door leaf and so on. However, the technical solutions of these patents are not completely separated from the processes of plastic spraying, transfer printing, spray painting, heat sealing, and gluing in the production process of security doors.

Chinese patent publication CN103061649B provides an "interlocking and buckling door leaf structure", which is a first door leaf plate interfitting mechanism formed on the side of the door frame substrate facing the first door leaf plate, and a second door leaf plate interembedding mechanism formed on the door leaf The frame base plate faces the side of the second door leaf plate; the first door leaf frame inter-embedding mechanism is formed on both sides of the first door leaf plate; the second door leaf frame inter-embedding mechanism is formed on both sides of the second door leaf plate; 1. A technical solution in which the second door leaf plate and a pair of door leaf frames are mutually embedded and interlocked. However, the deficiency of this patent solution is that although the welding process is eliminated, the folded edge is consistent with the opening and closing direction of the door, that is, the direction of force, and the thickness of the mutual embedding is only the thickness of the door panel. , the inter-embedding mechanism is easy to disengage after the door panel is hit or the number of openings increases, the overall strength and firmness are not enough, and this structure only solves the problem of the combination of the long sides between the door frame and the door panel, and does not solve the problem of both The bonding problem between the short sides.

CN103573112A disclosed by the Chinese patent, the "aluminum profile door leaf" technical solution provided also only solves the bonding problem of the long side between the inner frame and the door leaf plate, and does not solve the bonding problem between the two short sides.

Chinese patent publication CN103696661B provides the "assembled door leaf" technical solution. All parts are made by molds at one time. The parts of the door are assembled and limited by corresponding connecting pieces. All door accessories are assembled and formed. The door leaf parts on the rear side After the filling cavity is formed after installation, the inside of the rear part is brushed with foaming agent, filled with aluminum foil honeycomb paper, and then the front door leaf parts are assembled and installed. The door leaf integration is heat-synthesized by a heat-sealing machine with a shaping device. This technical solution still does not realize the integration of the front panel and the rear panel with the inner frame as a whole, and also needs to adopt a heat-synthesis molding process, and has not really realized assembly molding. For this reason, many manufacturers and people of insight carry out development and research, but there is not yet relatively satisfactory product to come out on the market so far.
