Description

Flat pressure airtight energy-saving sliding doors and windows

Technical field:

The utility model relates to a door and window for buildings, in particular to a flat-pressure airtight energy-saving push-pull door and window in which the push-pull fan of the push-pull door and window is flatly pressed on the sealing rail to achieve a closed state when the push-pull door is closed.

Background technique:

At present, commonly used sliding doors and windows are composed of a door and window frame with three sliding tracks (two of which are sliding rails for sliding fans and one for sliding rails for sliding fans) and sliding doors and windows with sealing strips on both sides of the inner groove. With the advantages of simple structure, convenient use, and no indoor space, it has become one of the mainstream doors and windows. However, ordinary sliding doors and windows are limited by the structure and switch operation mode. When the door and window sliding fan is in the open or closed state, the contact pressure between the sealing strip and the window frame slide rail does not change. It cannot be used as a door and window fan like ordinary casement doors and windows. When closing, the sealing strip is pressed flat and closed. Therefore, ordinary sliding doors and windows have poorer sealing performance than casement windows. Especially when the sealing strip is worn out, aged and deformed, the airtight effect is even worse, and even water and dust enter the room from the window frame, and the winter heat preservation is also affected. In order to solve this problem, some manufacturers increase the number of sealing strips on the sliding door and window frame and fan, and even add a track with a sealing strip on the frame to enhance the airtight performance of the doors and windows, but this often causes the opening and running resistance of the sliding fan. Correspondingly increased, you can't have both, and it is difficult to fundamentally solve the problem. In addition, the profiles of ordinary sliding doors and windows are relatively narrow, and usually only double-layer insulating glass can be installed, and the thermal insulation and sound insulation performance is also limited. Some areas (such as Tianjin) have restricted the use of sliding doors and windows in construction projects for the above reasons. Now more and more new projects have selected inner casement windows with better airtight and thermal insulation effects, but they have the obvious disadvantages of not only occupying indoor space, but also easily hurting indoor personnel, while outer casement windows without the above problems have The fall hazard has restricted its use to high-rise construction projects.

Invention content:

In order to overcome the deficiencies of the existing ordinary sliding doors and windows in terms of airtightness, thermal insulation and sound insulation, etc. and the influence brought by the use of inner casement windows, the utility model provides a flat-pressure airtight energy-saving sliding door and window, which maintains the advantages of ordinary sliding doors and windows. Basically, when the sliding doors and windows are closed, a method similar to that of the casement doors and windows is adopted, and at the same time, three layers of insulating glass can be conveniently installed, which significantly improves the sealing and thermal insulation performance of sliding doors and windows.

The technical scheme adopted by the utility model is: a flat pressure airtight stop rail is set between the two push-pull fan slide rails on the sliding door and window frame. Except that the two sides of the stop rail are provided with common sealing strip notches, the top of the stop rail is provided with a special seal that can be embedded. The larger notch of the strip, after the special sealing strip is installed in the top notch, the flat-pressed airtight retaining rail should be higher than or protrude from the two adjacent slide rails of the sliding fan as a whole, thus increasing the contact area between the sealing strip and the sliding fan and The airtightness is increased. In addition, when rain is directly poured into the outer window frame slot of the flat-pressed airtight retaining rail, the overall heightened flat-pressed airtight retaining rail is conducive to the rainwater overflowing the outer slide rail and discharged outside.

Install side pressure fittings that can cooperate with each other and have different structures at appropriate positions around the sliding door and window frame and the sliding fan. The side pressure fittings of the door and window frame are generally installed in the upper, lower and side grooves between the frame rail and the slide rail. In the mouth; the side pressure fittings of the door and window are generally installed in the grooves on the upper and lower sides of the fan, and the installation positions of the side pressure fittings of the door and window frame and the door and window should correspond to each other. The side pressure fittings on the top use the slope structure at a certain angle to contact each other to press the push-pull fan to the sealing rail, interact with the sealing strip on the side of the sealing rail and the sealing strip embedded in the top notch to press and seal, and push and pull at the same time The sealing strip in the fan groove is also pressed to the outside of the slide rail to form a press-fit seal, so that several press-fit seals work together to improve the airtightness. In order to extend the service life of the side pressure fittings and reduce the large resistance force when the doors and windows are opened due to the sealing of the side pressure, the side pressure fittings should be made of smooth and wear-resistant materials, and can even be made into rotating structures such as balls; The multi-point transmission closer is modified, and the opening on the locking hasp for the operation of the locking head is made into a slope-like structure with a certain angle. When the window handle is turned, the locking head has a certain degree on the locking hasp Running in the opening of an angle, it can make the sliding door and window sash flatly press against the sealing rail and slide rail like a side pressure fitting, and play a sealing role; while playing a sealing role, it is necessary to reduce the pressure of the door and window when the door and window are opened due to the side pressure sealing Larger blocking force can make the opening on the locking hasp for the operation of the locking hasp to form a running structure with a certain angle to the rear. Running in the opening, so that the sliding door and window can be pulled forward a few millimeters while playing the role of side pressure sealing; on the contrary, when the window is opened, the sliding door and window can be automatically pulled back a few millimeters, and the opening of the sliding door is more labor-saving .

In order to ensure the sealing performance of doors and windows, sealing blocks of different structures must be installed in the matching notches of the door and window frames, and the sealing strips should be used to achieve a good sealing effect.

In order to make the sliding door and window sash move horizontally to both sides and press against the sealing rail smoothly when it is close to the closed position, it is necessary to increase the space distance of the pulley’s lateral movement on the basis of the ordinary door and window pulley structure. A corresponding space is provided between the pulley frames, and the pulleys move in series on the pulley shaft; or a corresponding space is provided between the pulley block frame and the outer frame, and the pulley block frame moves in series on the balance shaft. In this way, when the push-pull fan is laterally pressed and sealed, only the pulley frame or outer frame moves in series with the push-pull fan, while the pulley or the pulley block frame remains on the original slide rail to ensure the flat-pressed and sealed effect of the door and window.

On the sides where the two sliding door and window sashes overlap each other, a sealing strip of corresponding shape can be installed to ensure the airtightness of the overlap.

In terms of cross-sectional structure, the push-pull fan should reduce the thickness of the profile bar on the part where the glass is installed, and correspondingly reduce the thickness of the glass bead, and even change the cavity structure into a unilateral shape, so that the distance can be increased to facilitate the installation of three layers insulating glass.

Between the two outer layers of glass around the three-layer hollow glass structure, there is a glass spacer with a groove in the middle, and a 3mm-5mm thick glass is installed in the groove, forming a three-glass structure with the outer two glasses; to ensure The middle glass is not easy to break and has tightness, and the groove must be filled with a soft gasket; the middle glass can also be replaced with polycarbonate plate or laminated glass, and combined with a general protection and anti-theft device to form a protection and anti-theft energy-saving door and window.

The lower part of the sliding door and window frame sealing retaining rail section is designed with a Y-shaped structure. This structure can open the indoor notch to the outdoor drainage channel under the premise of isolating the steel lining reinforcement cavity no matter whether the sliding sliding rail of the sliding fan is indoors or outdoors. Cooperate with the automatic drainer to discharge the rainwater entering the notch on one side of the window frame indoors to the outside.

The frame of flat-press airtight energy-saving sliding doors and windows can be made into a three-rail structure. This structure reduces the structure of push-pull yarn fans and saves the material used for outer frame profiles. The doors and windows are exactly the same, and are mostly used for sliding doors. If it is necessary to add gauze fans, other structures can be used to solve the problem; the cross-sectional view of the three-rail frame structure can also be widened. This structure increases the thickness of the doors, windows and three-layer hollow glass structure, which is conducive to improving flat pressure and airtightness Various performances of energy-saving sliding doors and windows.

The beneficial effects of the utility model are: on the basis of maintaining the advantages of sliding doors and windows, the performance of watertightness, airtightness, thermal insulation and sound insulation is enhanced, and the structure is relatively simple.

Detailed ways:

Please refer to Fig. 1～Fig. 40, the specific embodiment of the present utility model is as follows: 1 among Fig. 1 is the outer frame of sliding door and window, 2 is the outer leaf of sliding door and window, and 3 is the inner leaf of sliding door and window. In Fig. 4, there is a notch 5 at the top of the sealing retaining rail 4 in the side outer frame 1, and a special sealing strip 6 is embedded in the notch 5. The sealing strip 6 can be made of soft materials such as rubber and plastic, or can be made of soft and hard materials. Made by extrusion process, that is, the middle part is hard material, and the two sides are soft rubber strips for sealing. The sealing retaining rail 4 that is embedded with sealing strip 6 can protrude from the slide rails 7 of a certain size on both sides. A frame side pressure fitting 8 is installed in the groove between the stop rail 4 and a slide rail 7. Figures 5 to 7 are three views of the frame side pressure fitting. The side view is approximately L-shaped, and one side is screwed into the groove In the mouth, the outer end of the other side forms a slope-shaped structure 9 at a certain angle; a side pressure fitting 10 is installed in the groove opening of the sliding door and window sash 2 corresponding to the slide rail 7, and Fig. 8 to Fig. 10 are side pressure fittings 10. In the three views of the fittings, the outer end of the fan side pressing fitting 10 is in the shape of a slope 11 in a circular arc shape. 11 interacts with the slope-shaped structure 9 at the outer end of the frame side pressure fitting 8, so that the side of the push-pull fan is flatly pressed on the sealing strip 6 and the sealing strip 12 on the side of the sealing rail 4, and at the same time, the sealing strip 13, 14 is also pressed on the outer surface of the slide rail 7 to form several flat pressure seals. Fig. 11 is a cross-sectional view of the lower outer frame 1 of the door and window 1 and the push-pull fans 2, 3. Its sealing structure and method are similar to those in Fig. 4, except that (the lower rail 7 is equipped with a guide rail bar for the switch operation of the push-pull fan). The push-pull fans 2 and 3 cooperate with lap seals, as shown in Figure 20; therefore, sealing blocks 15 must be installed in the grooves of the upper and lower frames. The sealing block 15 also has a side pressure fitting structure 16; the corners of the upper and lower grooves of the push-pull fans 2 and 3 are equipped with a sealing side pressure fitting 17, and Fig. 12 to Fig. 14 are three views of the sealing side pressure fitting 17. When the leaves 2 and 3 are running close to the closed state, in addition to interacting with the side pressure plate 16 of the sealing block 15 to make the push-pull door and window sash laterally flat-pressed and sealed, a sealing strip can be installed on it to seal the gap between the groove of the push-pull fan and the slide rail. . There is a guide rail bar 18 at the top of the slide rail to guide the pulley movement of the push-pull fan. After the sealing retaining rail 4 is equipped with a special sealing strip 6, the overall height can be higher than the guide rail bar 18 several millimeters, which is conducive to rainwater discharge. The side pressure fittings and sealing side pressure fittings can be designed in different structures. Figures 23 to 25 are three views of another kind of sealing side pressure fittings. Fig. 18 is a cross-sectional view of the frame fan with the modified multi-point actuator for side flat pressure sealing. Fig. 19 is the main body diagram of the multi-point actuator. Its installation and use methods are the same as those of ordinary actuators, except that The locking head 19 and the locking hasp 20 of the multi-point transmission closer are modified. Figures 20 to 22 are three views of the multi-point transmission locking hasp. The locking hasp 20 is used to lock the opening of the locking head 19. 21 is made into a structure with a certain inclination.

The stop rail and slide rail play a role of airtightness; while playing the role of airtightness, to reduce the large resistance force when the doors and windows are opened due to side pressure airtightness, the opening on the locking hasp for locking the buckle head can be locked at the same time. Make a running structure 23 with a certain angle to the rear. When the window handle 22 is twisted, its locking buckle head runs in the locking hasp opening with a certain angle, and the sliding door and window can be continued while playing the role of side pressure sealing. Pull a few millimeters forward; on the contrary, when the window is opened, the sliding door and window sash can be automatically pulled back a few millimeters, and it is more labor-saving to open the sliding sash.
