Abstract

The utility model belongs to anti-theft door type, which specifically relates to a cover for reinforcing an anti-theft door. The utility model is formed by that a right-angle rim folded by a backboard of a door leaf is engaged with a sealing edge on periphery of a panel. The utility model has the technical proposal that a reinforcing internal support is arranged between the right-angle rim and a face sealing seam. The utility model has the advantages of high intensity, great angular rigidity, tight closedown, and good anti-prizing effect.

Description

The antitheft door closure mouth of reinforcing that supports in having

Belong to antitheft class, be specifically related to a kind of door leaf lid mouth structure of security door.

At present, the security door door leaf of market sale lid mouth all is to adopt the three ply board thick structure.Its manufacture process is: earlier the door leaf back plate edges is converted into the right-angle side edge, again the door skin edge is carried out the edge sealing seaming with edge banding machine to the right-angle side edge, have the thick door leaf lid mouth of three ply board material thereby form.This by backboard be converted into right-angle side along and the thick lid mouth of three ply board formed of panel edge sealing seaming, the one, thiner, the 2nd, the destruction that is difficult to resist pry, pick-proof poor performance.

The purpose of this utility model provides a kind of interior antitheft door closure mouth of reinforcing that supports that has, and improves lid mouth self intensity by reinforcing, and strengthens the pick-proof performance.

The technical solution of the utility model is: have on the lid mouth basis of three ply board thick structure, provide a kind of interior antitheft door closure mouth of reinforcing that supports that has.It is made up of right-angle side edge and panel edge sealing seaming that the door leaf backboard is converted into, and technical characterictic is to be provided with interior support between right-angle side edge that backboard is converted into and panel inner surface interlayer.Interior support can be become by the bent inflection of backboard periphery self, but its manufacturing process difficulty is big, also can be arranged to the steel plate frame that cross sectional shape is the opening rectangular channel separately.Reinforce lid mouthful periphery smooth firmly the technical program also is provided with support frame at door leaf abdominal cavity periphery for making, it fuses with the interior support edge of lid mouthful.For guaranteeing that reinforcing the edge sealing seaming that covers the actinal surface plate can sting the right-angle side of backboard firmly along envelope, the technical program also can be equipped with groove along root at the right-angle side that backboard is converted into, and panel edge sealing seaming inserts into the inner.The technical program can also be according to the structure needs, adopt the reinforcing lid mouth that supports in having on a limit of door leaf, on two limits, on three limits or on four limits.

The utility model has the advantages that: lid is mouthful thick, intensity is high, rigidity is big, it is tight to close, the pick-proof performance is good.

The antitheft door closure mouth of reinforcing that supports in 1: four limit of embodiment has is provided by following accompanying drawing:

Fig. 1 is the antitheft door closure mouth of the reinforcing front view that supports in four limits have;

Fig. 2 is a vertical view;

Fig. 3 is a left view;

Fig. 4 is the schematic diagram that lid mouthful root has groove.

The drawing explanation: sequence number 1 is a backboard among the figure; The 2nd, panel; The 3rd, interior support; The 4th, support frame; The 5th, the insulation filler; The 6th, groove.

Bracing reinforcement lid mouth in all adopt on present embodiment door leaf four limits, its middle cover cause for gossip border is of a size of 10 * 10 millimeters.

The antitheft door closure mouth of reinforcing that supports in having on 2: three limits of embodiment is provided by following accompanying drawing;

Fig. 5 is the antitheft door closure mouth of the reinforcing front view that supports in three limits have;

Fig. 6 is a left view.

Bracing reinforcement lid mouth in all adopt present embodiment door leaf dual-side and top, bottom is panel and backboard while and flute profile support edge sealing seaming, constitutes one in front and one in back parallel base Gai Kou.
