Abstract

The utility model relates to a PVC micro-foam plastic door. One side of the door frame of the PVC micro-foam plastic door is provided with a concave-convex faying face, a hollow U-shaped groove and a concave-convex wedge opening, and the other side is a profiled-bar component provided with decorative edges. A main door panel is inserted into the door frame, passes through the hollow U-shaped groove, and then is adhered into integration with the door frame via the concave-convex faying face and the concave-convex wedge opening. A small door panel whose periphery is sealed by decorative edge-sealing strips is also adhered onto the main door panel.

Description

The micro-foamed plastic door

The utility model relates to a kind of door, particularly a kind of door member and composite member thereof with PVC micro-foamed plastic material.

Traditional door is with doorframe and door-plate combination, methods such as adopting joggle, interlockings more, fuse, be bonding is made, because can there be problems such as the easy loose or dislocation of bonding surface, the aesthetic feeling that disfeatures, complex manufacturing technology to some extent in factors such as the material of doorframe and door-plate and manufacture craft.The CN210751 utility model patent discloses a kind of plastic door that improves structure, has more efficiently improved the combined characteristic of plastic door, has increased the aesthetic feeling of door.But this door is comparatively complicated, and only especially at the improvement of the panelling structure of assembly different materials on plastic door frame, still exists shortcoming such as extensively to promote, manufacturing process complexity, durability are good inadequately.

The purpose of this utility model is to provide a kind of micro-foamed plastic door, and it is made by the micro-foamed plastic shaped component, and assembly technology is simple, and firmly, attractive in appearance, indeformable, practicality is good.

The purpose of this utility model is to realize like this, a kind of micro-foamed plastic door promptly is provided, comprise doorframe, main door-plate, little door-plate and decoration edge sealing bar, wherein, doorframe has concavo-convex bonding surface, concavo-convex wedge mouth and several hollow U type groove by one group of corresponding mutually one side, and another side has the profile shapes member of upholstery border to being connected into the door frame of two groups of mutual correspondences and four welded corner joints; Main door-plate four edges is inserted in respectively in the middle of four door frames, passes hollow U type groove, and is connected as a single entity by the bonding and doorframe of concavo-convex bonding surface and concavo-convex wedge mouth; The bonding little door-plate in the two sides of main door-plate, it is on every side to decorate the sealing-in of edge sealing bar.

The utility model is made through high-strength adhesive is bonding by PVC micro-foamed plastic shaped component, and assembly technology is simple, high-strength bonding not loose, do not come off, indeformable, profile is solemnly neat and artistic, the product specification height.Hollow structure design in the doorframe, the bulk strength of raising door guarantees the Men Buhui distortion, has strengthened the impact resistance of door, has also reduced the consumption of material.Add little door-plate on the main door-plate and decorate the edge sealing bar, increase the overall aesthetic of door, strengthen the fastness and the intensity of door.

Description of drawings of the present utility model is as follows:

Fig. 1 is the overall structure schematic diagram of the utility model door;

Fig. 2 is along the sectional view of A-A line among Fig. 1;

Fig. 3 is along the sectional view of B-B line among Fig. 1.

Be described in further detail below in conjunction with 1,2,3 pairs of the utility model of accompanying drawing: the utility model is to be stock with emerging substitute materials for wood PVC micro-foamed plastic, profile shapes and flat-sheet material with compression moulding are main member, bonding based on high-strength adhesive, and the method that is aided with welding produces a kind of type gate with unit construction.Its main member has doorframe 1, main door-plate 2, wicket plate 3 and decorates edge sealing bar 4, and wherein doorframe 1 and decoration edge sealing bar 4 are the profile shapes member, and main door-plate 2 and wicket plate 3 are the flat-sheet material member.Doorframe 1 simultaneously is the particular configuration that has concavo-convex bonding surface 8, hollow U type groove 7 and socket wedge mouth 9 by one group, another side is the doorframe profile shapes member that frame has upholstery border 6, through mutual corresponding bonding composing frame frame 1a, 1b, door frame with two groups of different sizes is corresponding mutually in twos again, and constitutes in the welding of joint line 5 places at four angles.During integral installation the four edges of main door-plate 2 is plugged on the centre of door frame 1a, 1b respectively, insert respectively between one group of doorframe profile shapes member 1a, 1b that mutually combines on each the bar limit that is about to main door-plate 2, pass hollow U type groove 7, and be bonded as one with doorframe 1a, 1b by concavo-convex bonding surface 8 and concavo-convex wedge mouth 9.Concavo-convex bonding surface 8 between several hollow U type groove 7 on door frame 1a, the 1b, particularly the concavo-convex wedge mouth 9 of hollow U type groove 10 both sides on outermost limit is the whole bonding surface of door, with the bonding comparison in plane, its bonding force is much bigger, can make the combination between each member tightr, can not become flexible and come off, and bonding surface is smooth good looking appearance.The hollow structure that hollow U type

groove

7,10 in the doorframe forms not only can reduce raw-material consumption, and has strengthened the bulk strength of door, has guaranteed the Men Buhui distortion, improves the resistance to impact of door, makes door firm and durable more.The all bonding wicket plate 3 in the two sides of main door-plate 2 is around it and with decorating 4 sealing-ins of edge sealing bar.The design of installing wicket plate 3 and decoration edge sealing bar 4 additional can increase the integral thickness and the intensity of door.

Claims
