Description

Technical Field

[0001] The invention belongs to the field of hardware accessories for doors and windows, in particular to a quick-install part, a damping sliding part and a wind brace for doors and windows. Background Art

[0002] The wind support of doors and windows is a connecting rod or slider connecting rod mechanism, one part of which is installed on the fixed frame of the door and window, and the other part is installed on the sash of the door and window that can be opened and closed. When the sash is opened, the connecting rod can connect and support the sash to prevent the sash from closing suddenly due to force; the maximum angle of the sash when it is opened can also be controlled by adjusting the installation position of the slider located on the frame.

[0003] Traditional wind bracing has the following main disadvantages:

[0004] 1) The adjustment slider accessories are exposed, easy to be contaminated, and have a short service life;

[0005] 2) There is no obvious mark on the limit position at the maximum opening angle, which means that it is impossible to determine whether the adjustment slider has slid to the limit position. If the torque for opening or closing the door is large, the slider is easily damaged;

[0006] 3) The wind bracing structure is not easy to disassemble, which is very inconvenient when it is necessary to cancel the opening limit of the wind bracing. Summary of the invention

[0033] This embodiment is a wind bracing structure for doors and windows and a quick-install component and a damping sliding component used in the wind bracing structure. The technical solution is further explained below in conjunction with the accompanying drawings.

[0034] like Figure 1 and Figure 2 As shown, the wind brace for doors and windows includes a brace rod 2, a quick-fitting part 1 located on a hardware notch of a frame 5, and a damping sliding part located on a hardware notch of a sash 6, wherein the damping sliding part includes a long strip sliding block 3 slidably arranged on the sash 6 and a limit stopper 4 fixed on the sash 6. The head end of the brace rod 2 is rotatably and detachably connected to the quick-fitting part 1, and the tail end is rotatably connected to the sliding block 3.

[0035] like Figures 4 to 7 As shown, the quick-install part 1 includes a long strip base 11, a locking piece 12 and a detachable pin Ⅰ7. The bottom of the base 11 is mounted on the hardware slot of the frame 5 through a hook 18, and is fixed to the frame 5 through two mounting screws 21. The locking piece 12 is slidably connected to the base 11. Specifically, the locking piece 11 is a C-shaped slide member, and the base 11 is an I-shaped slide member matching the C-shaped slide structure.

[0036] The base 11 is provided with a pin hole Ⅰ17, and the locking piece 12 is provided with a gourd hole 13 matched with the pin hole Ⅰ17. The large diameter of the gourd hole 13 is not less than the diameter of the pin hole Ⅰ17, and the small diameter is less than the diameter of the pin hole Ⅰ17. The pin Ⅰ7 is a stepped pin with two different diameters. The large diameter part of the pin Ⅰ7 matches the pin hole Ⅰ17, and the small diameter part matches the small diameter hole of the gourd hole 13. The large diameter hole and the small diameter hole of the gourd hole 13 are respectively matched with the pin hole Ⅰ17 by sliding the locking piece 12 to loosen or lock the pin Ⅰ7. The top of the pin Ⅰ7 is riveted to the support rod 2. The pin Ⅰ7 rotates in the pin hole Ⅰ17 and is detachable, so that the disassembly and assembly of the support rod 5 is realized, which is simple and convenient.

[0037] The base 11 and the locking piece 12 are positioned at a sliding position by an elastic member, and the sliding position is the position of the locking piece 12 when the large diameter hole and the small diameter hole of the gourd hole 13 correspond to the pin hole I 17 respectively.

[0038] Specifically, the elastic member includes a spring 15 and a steel ball 16. The base 11 is provided with a blind hole 14 for placing the spring. The steel ball 16 is placed on the top of the spring 15. The locking plate 12 is provided with a left positioning groove 19 and a right positioning groove 20 for clamping the steel ball 16. When the steel ball 16 cooperates with the left positioning groove 19, the small-diameter hole corresponding to the gourd hole 13 cooperates with the pin hole Ⅰ17. When the steel ball 16 cooperates with the right positioning groove 20, the large-diameter hole corresponding to the gourd hole 13 cooperates with the pin hole Ⅰ17.

[0039] like Figures 8 to 11 As shown, the damping sliding member includes a long strip slider 3 slidably arranged on the sash 6 and a limit stopper 4 fixed on the sash 6 by a fastening screw 42. The limit stopper 4 and the slider 3 are both hardware pieces in the shape of a Chinese character "X" and are clamped in the hardware slot of the sash 6. The sliding tracks of the limit stopper 4 and the slider 3 are colinear to limit the slider 3. The installation position of the limit stopper 4 can be arbitrarily set according to the opening angle of the door and window. The slider 3 is provided with a pin hole II 32, a trapezoidal block 36 and an adjusting bolt 33. The lower end of the pin II 8 is riveted to the support rod 2, and the pin II 8 is rotatably connected in the pin hole II 32 to form a quick-fitting part 1. Figure 2 The wind bracing structure shown in the figure. The slider 3 is located at the bottom of the fan 6, which can reduce pollution and increase the service life. The quick-install part 1 is arranged on the frame 5 to facilitate the disassembly operation.

[0040] The side of the slider 3 that matches the fan 6 is provided with a trapezoidal groove 35. The trapezoidal block 36 matches the inclined surface of the trapezoidal groove 35. The adjusting bolt 33 passes through the slider 3 and is screwed to the trapezoidal block 36. By screwing the adjusting bolt 33, the trapezoidal block 36 can be driven to move up and down, thereby adjusting the matching clearance between the slider 3 and the hardware notch of the fan 6 to control the damping during sliding. For example, when the slider damping of the slider 3 is too small, refer to Fig.11 , screwing the adjusting bolt 33 makes the trapezoidal block 36 move downward, and the trapezoidal block 36 squeezes the trapezoidal groove 35 to increase the sliding damping between the slider 3 and the hardware notch of the fan 6.

[0041] When limiting, the front end of the limit stopper 4 contacts the rear end of the slider 3, and a buffering elastic member is provided at the front end of the limit stopper 4. Specifically, the elastic member is a bow-shaped spring sheet 41, and the rear end of the slider 3 is provided with a holder 31 matching the spring sheet 41. When sliding to the limit position, the holder 31 squeezes the spring sheet 41 to achieve damping and limiting.
