Door and window protective sleeve

Abstract

The invention provides a door and window protective sleeve. The door and window protective sleeve comprises a door and window frame, wherein a protective sleeve main body is arranged at the splicing position of the door and window frame, the protective sleeve main body is L-shaped, a mounting hole is formed in the protective sleeve main body, a fixing device is arranged in the mounting hole, a chamfer is arranged at the bending position of the protective sleeve main body, the protective sleeve main body comprises a first side plate and a second side plate, the first side plate is connected with the second side plate through a connecting plate, a sealing wool top is arranged on the first side plate, and an adsorption strip is arranged on the connecting plate. The protective sleeve main bodycan be quickly sheathed at the splicing position of the door and window frame through a channel formed by the first side plate, the second side plate and the connecting plate, and the protective sleeve main body is fixedly connected with the door and window frame through the fixing device, so that the assembly operation of the protective sleeve is simple, the production efficiency is improved, the sealing wool top can achieve a good sealing effect, the resistance during the movement of the door and window frame is reduced, the stability of a door and window is ensured, the adsorption strip can eliminate excess collision force or supplement the insufficient force during closing, and secondary operation is avoided.

Description

technical field [0001] The invention relates to the technical field of door and window equipment, in particular to a door and window protective cover. Background technique [0002] Doors and windows are divided into enclosure components or partition components according to their positions, and have different design requirements to have functions such as heat preservation, heat insulation, sound insulation, waterproof, and fire prevention. The new requirement is energy saving. The lost heat accounts for about 25% of the total heating heat consumption. The airtight requirements of doors and windows is an important content in energy-saving design. Doors and windows are an important part of the building envelope system. [0003] With the improvement of living standards, people have put forward higher requirements for the quality of building doors and windows and the style of doors and windows. Production usually adopts mortise and mortise joints. Due to the use of glue, the m...

Problems solved by technology

[0003] With the improvement of living standards, people have put forward higher requirements for the quality of building doors and windows and the style of doors and windows. Production usually adopts mortise and mortise joints. Due to the use of glue, the mortise and tenon joints of doors and windows are often too simple. At the same time, degumming is prone to occur due to reasons such as handling, painting, assembly, and transportation. It can be effectively supported, and even some metal or plastic doors and windows will use mortise joints, and these materials tend to form sharp corners at the joints, which are easy to cause scratches
