Abstract

The utility model relates to a theftproof door. The door body of the theftproof door is composed of a rectangular casing made of a metal plate and having an opening and a non-metal plate arranged in the opening of the rectangular casing and having heat insulation and sound insulation. The utility model has the property of a theftproof door, but also has the properties of the other types of doors, such as heat insulation, sound insulation, beautiful performance, etc. Compared with the existing theftproof door, the cost of the utility model is not increased, and the utility model has convenient use.

Description

A kind of security door

The utility model relates to a kind of security door, especially is suitable for civilian security door.

Security door of the prior art, comprise and be used to be installed in the rigidity hollow frame of body of wall opening part and be arranged on the interior door body of this hollow frame, the door body is connected with hollow frame one inboard by the link that is arranged at a side, and the locking device of setting between hollow frame and door body.In general, the framework of this kind security door and a door body are made by metal material, and its surface is firm, except that opening with key locking device could open door, adopt alternate manner to be difficult to accomplish, so it has extraordinary antitheft effect.But it is not,, very attractive in appearance from external form so this kind door is incubated, sound insulation value is poor because metal material is the good conductor of heat yet.In addition, the door body of this kind security door directly contacts with the protuberance of framework when folding, not only seals badly, and usually ear-piercing noise can take place, the pollution surrounding environment.

For addressing the above problem, the solution that adopts usually in the prior art is to add one again in the inboard of security door by the wooden door of manufacturing with insulation, sound insulation function, but this kind mode is quite inconvenient in use, but also has increased decoration cost.

Task of the present utility model provides a kind of improved security door, and it is that nonmetals and metal material are combined a kind of door of making, to overcome above-mentioned weak point.

For finishing above-mentioned task, the utility model comprises and is used to be installed in the rigidity hollow frame of body of wall opening part and is arranged on the interior door body of this hollow frame that a door body is connected with hollow frame one inboard by the link that is arranged at a side.Described door body is to be made the rectangular case of opening and be arranged in this rectangular case opening and non-metal board that have insulation, sound insulation value constitutes by metal sheet.

The inner surface of the described rectangular case of being made by metal sheet is provided with perpendicular rib or cross rib muscle, and nonmetal plate is installed in the housing by the rectangular case opening direction, and by junction plate it is combined.Nonmetal plate can be made of wooden plate or foamed plastics plate or other similarity pieces.

The described hollow frame one end protuberance that extends internally out, and contact a side at this protuberance with a door physical efficiency and be provided with the sealing ring of making by soft material.

Described door body periphery has the gradient of inwardly shrinking gradually, in order to the folding of door.

Because the utility model is to combine the door made from nonmetals and metal material, so it promptly has the characteristic of security door, the insulation, sound insulation and the characteristic such as elegant in appearance that have other type door again, compare with existing security door, do not increase how many costs, and use is quite convenient.

Below in conjunction with drawings and Examples the utility model is elaborated.

Accompanying drawing 1 is the utility model part section front elevational schematic;

Accompanying drawing 2 is schematic rear view of Fig. 1;

Accompanying drawing 3 be among Fig. 1 A-A to sectional view;

Accompanying drawing 4 be among Fig. 1 B-B to sectional view.

Referring to Fig. 1, this security door comprises the hollow frame 1 of rigidity, and vertical edge inboard of this hollow frame is provided with link 2, and door 3 is connected with link 2 other ends in a side.Link 2 can be made of flap, and door 3 can rotate by the axle on flap.Door 3 can be made the rectangular case 31 of an opening by metal sheet, from the section of Fig. 1 part as can be seen rectangular case 31 inner surfaces be provided with cross rib muscle 311 and perpendicular rib 312, in order to reinforce rectangular case 31 and to make this rectangular case and the non-metal board 32 that is installed in its inboard certain space distance separately, can play insulation, deadening better.

Accompanying drawing 2 provides the rear elevation of Fig. 1, it is to increase a nonmetal plate 32 on the basis of former security door, its specific embodiment is that the another side of door 3 is made by nonmetal plate 32, and can be designed to various floral designs at nonmetal plate 32 external surfaces, it can play beauty function, can play the effect of insulation, sound insulation again.Nonmetal plate 32 can be made of wooden plate or foamed plastics plate or its plate that similarly has insulation, sound insulation.

Referring to Fig. 3 and Fig. 4, hollow 11 of hollow frame 1 is to be used for being connected with body of wall, and its hollow 11 interior filling and body of wall attachment make hollow frame 1 and body of wall form one.One end of hollow frame 1 protuberance 12 that extends internally out, the inboard of this protuberance promptly can contact a side with door and be fixed with a sealing ring 6, and it can play sealing function, can prevent that again door 3 from directly contacting with hollow frame 1, so can not produce noise when door 3 foldings.The rectangular case 31 of the opening that door 3 is manufactured by metal sheet, the opening part of this rectangular case is equipped with nonmetal plate 32, and rectangular case 31 and nonmetal plate 32 are combined it by junction plate 4 and junction plate 5.Inwardly shrink formation one gradient around the rectangular case 31 gradually, to be convenient to the folding of door 3.
