Description

Technical Field

[0001] The utility model relates to the technical field of casement windows, in particular to a casement window structure in a unit curtain wall. Background Art

[0002] Unit curtain wall refers to a basic unit of curtain wall structure made of various wall panels and supporting frames in the factory, which is directly installed on the main structure of the building curtain wall. The building curtain wall must have an openable part according to the setting requirements to meet the ventilation function of the room. The window opening methods of the unit curtain wall are divided into: casement windows, sliding windows, top-hung windows, bottom-hung windows, and outward-opening and inner-shading windows. Among them, casement windows are widely used because of their good ventilation effect. Casement windows are divided into inward-opening and outward-opening methods. Outward-opening means that the window opens outward, which is suitable for places with larger external space. Inward-opening means that the window opens inward, which is suitable for areas with limited space.

[0003] The existing casement windows are fixed by hinges after opening, and the supporting force is weak. The windows can easily be closed due to strong winds, which can easily cause damage to the window frame and even shatter the glass in severe cases. Therefore, a unit curtain wall casement window structure is proposed to solve the above problems. Utility Model Content

[0004] In order to solve the above technical problems, a casement window structure in a unit curtain wall is provided. This technical solution solves the problem that the casement window is not firmly fixed, which makes it easy for the window to be closed and damaged by wind.

[0005] In order to achieve the above purpose, the technical solution adopted by this utility model is:

[0006] The window frame is hinged to the bottom of the window frame by a plurality of damping hinges, wherein one end of the limit rod is rotatably connected to the lower end of the glass frame, and the other end of the limit rod is slidably connected to the inner wall of the window frame. A locking tongue is provided in the middle of one side frame of the glass frame, and a handle is installed on the outer side of the glass frame, and the handle is at the same height as the locking tongue. A limiting groove is provided at the lower end of the window frame, and a limiting tooth is uniformly arranged inside the limiting groove. The limiting teeth are uniformly arranged in the horizontal direction and fixedly connected to the inner wall of the limiting groove for sliding connection with the limiting rod inside the limiting groove. The limiting rod has two ends fixedly connected to the sliding block on both sides of one end of the limit rod, and the sliding block is cylindrically arranged. The circumferential side of the sliding block is slidably connected to the sliding groove. A clamping block is provided inside the limit rod, and the clamping block is slidably connected to the inner wall of the limit rod, and the other end of the limit rod is provided with a rotating hole.

[0007] Preferably, a sliding groove is provided inside the limiting groove, and the sliding groove passes through the limiting groove.

[0008] Preferably, the middle part of the clamping block is fixedly connected to the movable block, the surface of the movable block is slidably connected to the inner wall of the limiting rod, the side of the movable block close to the inside of the limiting rod is fixedly connected to a spring, the other end of the spring is fixedly connected to the inner wall of the limiting rod, and the end of the clamping block located inside the limiting rod is fixedly connected to a clamping block pull rope.

[0009] Preferably, a rotating shaft is rotatably connected inside the rotating hole, an upper end of the rotating shaft is fixedly connected to a fixing block, and the fixing block is fixedly connected to the bottom frame of the glass frame.

[0010] Preferably, a sound insulation pad is provided on the periphery of the inner frame of the window frame, and a buffer pad is connected to the outer side of the frame on one side of the glass frame close to the damping hinge, and the buffer pad is arranged longitudinally.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This solution fixes the glass frame by setting a limit rod. A card block is set at one end of the limit rod. Turn the handle to make the card block pull the card block with a pull rope, so that the card block slides toward the inside of the limit rod. The card block disengages from the limit teeth set inside the window frame. After opening a certain angle, release the handle. The card block extends out under the elastic force of the spring and is stuck between the teeth of the limit teeth. The limit teeth are tilted to one side, which can resist the card block to lock the limit rod. The glass frame cannot be closed by external force, preventing the wind from blowing and causing the glass frame to close. If the force is large, the glass may be shattered.

[0013] 2. A buffer pad is set on one side of the glass frame. When the glass frame is opened to the maximum angle, the edge of the glass frame will contact the edge of the window frame. If the opening force is too large, it is easy to cause the glass to vibrate due to the reaction force, which may easily shatter the glass. Setting a buffer pad at the contact point can provide buffering when the glass frame contacts the window frame, thereby reducing the force applied to the glass. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0026] like Figures 1-3 As shown, a casement window structure in a unit curtain wall includes a window frame 1, a glass frame 2, a limiting rod 3 and a damping hinge 4. The window frame 1 and the glass frame 2 are hinged by multiple damping hinges 4. The damping hinge 4 has a built-in damping device to control the opening and closing speed of the glass frame 2, so as to prevent the glass from being damaged due to excessive force when the glass frame 2 is closed. One end of the limiting rod 3 is rotatably connected to the lower end of the glass frame 2, and the other end of the limiting rod 3 is slidably connected to the inside of the window frame 1. When the glass frame 2 is opened and closed, the end of the limiting rod 3 located inside the window frame 1 slides inside the window frame 1. At the same time, the limiting rod 3 also limits and fixes the glass frame 2, so that the glass frame 2 can be fixed after being opened to a certain angle, thereby preventing the glass from being shattered due to closing due to excessive wind force. A lock tongue 21 is provided in the middle of one side frame of the glass frame 2, which is used to lock the glass frame 2 when it is closed. A handle 22 is installed on the outside of the glass frame 2. Turning the handle 22 can control the lock tongue 21 to extend. The handle 22 is at the same height as the lock tongue 21. A limiting groove 12 is provided at the lower end of the window frame 1. A limiting tooth 13 is provided inside the limiting groove 12. The limiting tooth 13 is a tooth-shaped structure inclined to one side. A plurality of limiting teeth 13 are evenly arranged laterally and fixedly connected to the inner wall of the limiting groove 12. The interior of the limiting groove 12 is slidably connected to the limiting rod 3. A slide groove 14 is provided inside the limiting groove 12. The slide groove 14 runs through the limiting groove 12. The limiting rod 3 cooperates with the limiting tooth 13 to limit and fix the glass frame 2 by being stuck between the teeth of the limiting tooth 13.

[0027] like Figures 5-6As shown, the limit rod 3 includes a sliding block 31, a clamping block 32 and a rotating hole 33. The sliding blocks 31 are fixedly connected to the two sides of one end of the limit rod 3. The sliding block 31 is cylindrical and is arranged on the upper and lower sides of the limit rod 3. When the glass frame 2 is switched, the sliding block 31 slides inside the slide groove 14. The peripheral side of the sliding block 31 is slidably connected to the slide groove 14. The clamping block 32 is arranged inside the limit rod 3 and is slidably connected to the inner wall of the limit rod 3. The clamping block 32 extends out and is clamped between the teeth of the limiting teeth 13 to fix the limit rod 3. A rotating hole 33 is provided at the other end of the limit rod 3. The interior of the rotating hole 33 is rotatably connected to the rotating shaft 24. The upper end of the rotating shaft 24 is fixedly connected to the fixed block 23. The fixed block 23 is fixedly connected to the bottom frame of the glass frame 2. The clamping block 3 2 is fixedly connected to a movable block 34 in the middle part, and the surface of the movable block 34 is slidably connected to the inner wall of the limit rod 3. The movable block 34 is fixedly connected to a spring 35 on one side close to the inside of the limit rod 3, and the other end of the spring 35 is fixedly connected to the inner wall of the limit rod 3. The spring 35 applies elastic force to the movable block 34 to push the card block 32 to extend outward. The end of the card block 32 located inside the limit rod 3 is fixedly connected to a card block pull rope 36, which extends through the internal cavity of the limit rod 3 to the inside of the frame of the glass frame 2 and is connected to the rotating shaft of the handle 22. By rotating the handle 22, the card block pull rope 36 can be pulled to move the card block 32 toward the inside of the limit rod 3, so that the card block 32 can be disengaged from the teeth between the limit teeth 13, thereby unlocking the limit rod 3. At this time, the glass frame 2 can be rotated.

[0028] Among them, a sound insulation pad 11 is provided on the periphery of the inner frame of the window frame 1, which can improve the sound insulation performance of the window. A buffer pad 15 is connected to the outer side of the frame of the glass frame 2 close to the damping hinge 4. The buffer pad 15 is arranged longitudinally. When the glass frame 2 is opened to the maximum angle, the frame of the glass frame 2 will contact the frame of the window frame 1. If the opening force is large, it is easy to cause the glass to vibrate due to the reaction force, and it is easy to shatter the glass. The buffer pad 15 can provide buffering when contacting the frame of the window frame 1, thereby reducing the force exerted on the glass.

[0029] The principle of the present invention is as follows: the handle 22 is rotated to retract the lock tongue 21 into the interior of the glass frame 2 to unlock the glass frame 2. At the same time, the rotating shaft of the handle 22 pulls the card block rope 36 to make the card block 32 slide toward the interior of the limit rod 3, so that the card block 32 is disengaged from the limit tooth 13. At this time, the glass frame 2 is rotated, and the sliding block 31 slides along the slide groove 14. After opening to a certain angle, the handle 22 is released. The card block 32 extends out and is stuck between the teeth of the limit tooth 13 under the elastic force of the spring 35. The limit tooth 13 is tilted to one side and can resist the card block 32 to lock the limit rod 3, thereby preventing the glass frame 2 from being closed due to wind and shattering the glass with a large force.
