Description

Technical Field

[0001] The utility model relates to building doors and windows, specifically an anti-sinking pulley structure with guide rails in an opening fan system, which is mainly suitable for aluminum alloy sliding doors and windows in buildings with high opening frequency and poor future maintenance environment such as office buildings, teaching buildings, and residential buildings, and effectively improves the convenience of curtain wall opening fan systems. Background Art

[0002] With the rapid development of building curtain walls, the frequency of opening of building curtain wall sashes has increased significantly, and people have more stringent requirements for building curtain wall sashes. However, in actual applications, there are often the following problems: the curtain wall sashes are prone to corner drop, which increases maintenance costs, and structural design problems lead to low installation efficiency. In order to avoid the problem of corner drop, an anti-corner drop structure is set on the opening sash of the building curtain wall. It mostly uses glass pads installed inside the opening sash, but the form is too simple and the service life is short. At the end of the service life, the deformation of the profile and the aging of the hardware will still cause the opening sash to drop corners. After the corner drop, the closing resistance increases and the disassembly and maintenance are difficult, which is not conducive to the after-sales service of the curtain wall. Utility Model Content

[0003] The purpose of the utility model is to provide an anti-sinking pulley structure with a guide rail in an opening window system, which fundamentally solves the above-mentioned problems and has the advantages of low process precision requirements, strong adjustability, high durability, stable operation of the window sash unit, and convenient maintenance.

[0004] To achieve the above purpose, the utility model provides the following technical solution: the anti-sinking pulley structure with guide rails in the opening sash system, the sash unit is matched on the bottom frame through the anti-sinking pulley assembly, and its technical points are:

[0005] The window sash unit includes an L-shaped support unit, a curtain wall panel plugged into the outside of the support unit, and a corner guard snapped into the bottom of the support unit;

[0006] The anti-sinking pulley assembly includes a pair of L-shaped mounting plates arranged opposite to each other and a pulley limited therebetween; the L-shaped mounting plates are fixed to the support unit through an anti-sinking pulley back plate limited in the top of the support unit;

[0007] The upper limit of the bottom frame has an L-shaped frame fan body, on which is fixed an anti-sinking guide rail for cooperating with the pulley. The anti-sinking guide rail and the bottom of the frame fan body are limited by an anti-sinking guide rail pad. The outer side of the anti-sinking guide rail is tilted downward and a gap is left between the frame fan body.

[0008] Furthermore, a sealing strip is provided on the top contact end between the frame and sash body and the support unit.

[0009] Beneficial effects of the utility model:

[0010] In terms of the overall technical solution, under the premise of installing glass pads inside the original opening sash, in terms of specific structure, by changing the opening stroke of the window sash unit to a rolling stroke coordinated by a pulley and an anti-sinking guide rail made of stainless steel, the opening and closing resistance of the opening frame sash body is effectively reduced, and the durability is improved to prevent corner drop;

[0011] The L-shaped mounting plate, anti-sinking guide rail and anti-sinking guide rail pad are fixed to the supporting unit and the frame and sash body respectively by screws, which can realize the rapid disassembly and assembly of accessories, effectively reduce the difficulty of disassembly and maintenance, and facilitate the installation and maintenance of the curtain wall.

[0012] The matching clearance of the opening frame and sash body can be easily adjusted by simply adjusting the thickness of the anti-sinking guide rail pad, which can meet the installation requirements of multiple opening frame and sash systems with different clearances at the installation site. It avoids the production of window sash units of various sizes and specifications at the production end, which is convenient for installation and manufacturing.

[0013] By setting up a rigid anti-sinking guide rail, the weight of the entire window sash unit can be effectively carried, making the window sash more stable when moving and without deviation; the corner guard can effectively prevent the edge of the window sash from bumping, reducing maintenance costs. The pulley can run stably through the downward-inclined guidance and restriction of the outer side of the anti-sinking guide rail. When the window sash unit is opened outward, the outer slope of the anti-sinking guide rail plays a limiting role under the cooperation of the deadweight of the window sash unit; when the window sash unit is closed, an upward and inward pulling force is applied to the window sash unit, and the pulley returns to the horizontal section of the anti-sinking guide rail upward and inward, and is locked by the window sash lock on the window sash unit frame.

[0014] In summary, the utility model has the advantages of low process precision requirements, easy replacement and maintenance, strong versatility, stable operation of the window sash unit, safety and durability, and easy installation and maintenance. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following combination Figure 1~2, the specific contents of the utility model are described in detail through specific embodiments. The anti-sinking pulley structure with guide rails in the opening sash system, the window sash unit is matched on the bottom frame 10 through the anti-sinking pulley assembly 2. The bottom frame 10 is fixed on the floor unit (not shown in the figure), the L-shaped frame sash body 1 is fixed on the bottom frame 10 by buckles and / or bolts (not shown in the figure), the anti-sinking guide rail 3 and the anti-sinking guide rail pad 5 are fixed on the horizontal bottom of the L-shaped frame sash body 1 by screws 6, the outer side of the anti-sinking guide rail 3 is tilted downward, and there is a gap between the protruding part of the anti-sinking guide rail 3 and the frame sash body 1, and a sealing strip that cooperates with the vertical part of the support unit 7 is provided on the top contact end of the frame sash body 1. In addition, the anti-sinking guide rail 3 can be electroplated and colored to further improve the tolerance and make its appearance more beautiful.

[0018] The anti-sinking pulley assembly 2 includes a pair of L-shaped mounting plates 21 arranged opposite to each other and a pulley 22 limited therebetween. The window sash unit includes an L-shaped support unit 7, a curtain wall panel 8 plugged and matched on the outside of the support unit 7, and a corner guard 9 snapped and matched on the bottom of the support unit 7. The support unit 7 includes horizontal upper and lower connecting parts, a vertical middle body, a columnar matching part is provided on the inner side of the lower connecting part, and a frame structure with a rectangular cross section (not marked in the figure) is provided at the corner between the middle body and the upper connecting part and at the lower end of the upper connecting part to enhance the structural strength. The corner guard 9 is matched on the outer side of the lower connecting part of the support unit 7 through the card groove structure at both ends, and the curtain wall panel 8 is matched on the inner side of the lower connecting part through the columnar structure at its end. The L-shaped mounting plate 21 is fixed by the anti-sinking pulley back plate 4 and the screw 6 that passes through the rectangular frame of the upper connecting part of the support unit 7, and the end of the screw 6 is screwed into the columnar groove inside the rectangular frame.

[0019] Through the above structure, when the frame sash body 1, the supporting unit 7, the curtain wall panel 8, the corner guard 9 and the bottom frame 10 are all manufactured with the same standard size, the vertical position of the window sash unit can be adjusted by adjusting the thickness of the anti-sinking guide rail pad 5, thereby simplifying the production process and reducing the processing accuracy requirements.
