[0002] Building doors and windows are an indispensable part of buildings. In addition to the functions of lighting, ventilation and transportation, they also have the function of heat insulation;

[0003] When the building doors and windows are in use, they are generally of the sliding opening type and the hinged flap type. In the chemical building, the hinged flap type structure is generally adopted because of the good sealing effect. When the existing building doors and windows are hingedly installed, the hinge points are positioned by pins, which are often difficult to insert and install when they are deformed by force, making the installation inconvenient. Moreover, when the locking block is flipped and locked after the window is closed, the locking block becomes loose after a long period of wear and tear, making the window unstable.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example 1

[0024] See also Figure 1-5A novel chemical building door and window connection device comprises a window frame 1 and a window sash 2. A hinge arm 3 is arranged at the outer end of the window sash 2, a hinge seat 4 is arranged at the outer end of the window frame 1, a slide groove is arranged inside the hinge arm 3, and a spring 5 and a protrusion 6 are slid in the slide groove;

[0025] The convex head 6 adopts a convex eccentric circular shaft structure, which is convenient for rotation when clamped in the hinge seat 4;

[0026] During installation, the convex head 6 is clamped on the inner surface of the hinge seat 4, and the outer end of the convex head 6 is sleeved with a plane thrust bearing 7. The window sash 2 is turned over by the plane thrust bearing 7 and can be rotatably supported and stabilized. A pulling convex block 8 is fixed on the outer end of the convex head 6, and a handle 9 is fixed on the outer end of the window sash 2. A round shaft 10 is arranged in the handle 9, and a locking block 11 is fixed on the end face of the round shaft 10. A locking groove 12 is arranged on the inner side of the window frame 1, and the locking block 11 is locked in the locking groove 12. A slide groove is arranged on the inner surface of the locking block 11, and an extrusion block 13 and a compression spring 14 are arranged in the slide groove.

[0027] The outer end of the extrusion block 13 is provided with a rounded corner, and the extrusion block 13 is extruded on the inner surface of the window frame 1. After the locking block 11 is locked in the locking groove 12, the extrusion block 13 can be compressed and contracted, and the compression spring 14 squeezes the extrusion block 13 into the locking groove 12, which can be locked and positioned. Even if it is worn after frequent friction (the locking block 11 is covered with a rubber layer, and the outer surface of the extrusion block 13 is covered with a rubber layer), it will not loosen;

[0028] The outer end of the pull protrusion 8 extends out of the outer end of the hinge arm 3, and the outer surface of the pull protrusion 8 is slidably connected to the inner surface of the hinge arm 3. When the pull protrusion 8 moves, the two protrusions 6 can be driven to move, and can be separated from the hinge seat 4, and the window sash 2 can be pulled out for disassembly, which is convenient for disassembly;

[0029] The handle 9 adopts a straight handle structure, and is fixed on the outer surface of the window sash 2 at the upper and lower sides. The two handles and the lock block 11 structure prevent accidental opening, are more stable, and are suitable for chemical buildings.
