CN201915784U - Non-welding double layer seal type fireproof antitheft door with double grooves and four ditches - Google Patents

Abstract

The utility model relates to a non-welding double layer seal type fireproof antitheft door with double grooves and four ditches. The U-shaped edge of the door leaf inner wall is assembled with the J-shaped edge of the door leaf outer wall. The door is made from transfer printing metallic plates and the surface of the door is coated with a film. When the antitheft door is closed, an expansion sealing strip is hidden in the frame and the door ditch grooves, which is not easy to be damaged. When the door is closed, the double-groove sealing strips at periphery have the function of heat insulation, sound insulation, moist insulation and insect prevention. The limitation of undiversified products can be eliminated.

Description

Double flute four ditches do not have welding double seal formula fireproof and theftproof door

Technical field: the utility model relates to a kind of novel house lead in double flute four ditches of living in peace not to be had the welding totally enclosed type and turns to the structure design device of the fire safety security door of energy-conservation practicality freely, especially can wear combined pressure system one and door leaf and close and hide the bonding expanding sealing strips of double flute four limes marginis around the back and play fully closed " double flute four ditches do not have the totally enclosed type of welding fireproof and theftproof door " adopting in door leaf inwall, outer wall, the inner frame assembling.

Background technology: at present, the known fire safety security door of recognizing does not also often have these general double flute four ditches and does not have welding project organization double seal formula device product, development superpotential according to domestic and international building construction top gradeization, particularly to house the live in peace safe antitheft and the fire prevention of condition, heat insulation, sound insulation, damp proof insulation, 99.7% the hermetically-sealed construction that all adopts the fire safety security door of utilizing of insect protected is that ladder is pounced on and designed single seal groove and does the isolation sealing process, though they have light letter, easily processing, flexibly, many with its chief's advantage, but also exist not advanced simultaneously, unreasonable, it is heat insulation that door leaf and doorframe are closed the back, sound insulation, damp proof insulation, vermins-proof effect is poor, door is single with frame sealing strip project organization, can not play the fire-proof and theft-proof effect.It can be to play totally-enclosed buffer action inside and outside door leaf and doorframe are closed the back that the purpose of this utility model is to propose a kind of exactly, hinge is installed to be in and is hidden, expanding sealing strips is installed to be in and is hidden difficult drop-off in the groove, the Men Tiwu pad, door leaf and doorframe fit-up gap can be regulated voluntarily, its Men Tixian takes roll extrusion after the thermal vacuum transfer printing, pressing and forming technology, all pads of door leaf have been cancelled simultaneously, the unified common-use size of formation, be applicable to the distinctive double seal formula of the house fireproof and theftproof door fireproof and theftproof door of living in peace, and have volume adequacy, specification standardization, highly sensitive, good looking appearance is generous, not novel " double flute four ditches do not have welding double seal formula fireproof and theftproof door " that use value is high.

Summary of the invention: the purpose of this utility model is to realize like this, should " double flute four ditches do not have welding double seal formula fireproof and theftproof door " be made up of limes marginis, inner frame, expanding sealing strips, blind hinge, rotary connecting device and the structural component combined pressure system of wearing around the outer shape of doorframe, manhole ladder limit double flute, the door leaf inside and outside wall, hide after reaching door leaf and do not have pad, closing the groove expanding sealing strips play around totally-enclosed effect, switch 90 spend adjustable purpose freely.

Double flute four ditches that the utility model proposed do not have around the door leaf inwall of welding double seal formula fireproof and theftproof door U font limes marginis and door leaf outer wall all around J font limes marginis wear and set up dress jointly, its material is the transfer printing metal sheet, surperficial peritonaeum.

Described door leaf outer wall is to be with limes marginis type transfer printing metal cover-shaped body around rectangular, and its surrounding is respectively J font channel form, is mainly the workpiece assembling and is connected.

This utility model mainly is suitable for the fireproof and theftproof door of living in peace and uses, double flute four ditches that are absolutely necessary do not have welding double seal formula fireproof and theftproof door, and it wears in no pad door leaf after the combined pressure system, door body inner skeleton, the door body supplement by limes marginis around frame external surface lace shape and manhole ladder limit double flute door frame, the door inside and outside wall does not have chlorine PLASTIC LAMINATED, expanding sealing strips, blind hinge, fire-proof and theft-proof lock and form " double flute four ditches do not have the double seal of welding formula fireproof and theftproof door ".It by electric welding with hinge box be welded on the frame, screw rod respectively with no pad door leaf side be fastenedly connected, regulate again linking arm be a body and function steering spindle to be connected the two be one to form totally, be enclosed within the door opening that is installed in door in the framework installing hole respectively with dilating screw again.

It is mainly used to: the fireproof and theftproof door of the door of living in peace, by expanding sealing strips in the double flute of hiding play heat insulation, form every cigarette, sound insulation a kind of general and be convenient to the economical and practical light-duty fireproof and theftproof door product of living in peace of dismounting.
