[0002] Due to the advantages of saving space and being easy to open, lifting and sliding doors are widely used in home spaces, but the sealing of lifting and sliding doors has always been criticized. Especially in winter, the problem of air leakage is more prominent.

[0003] The overlap of the frame and leaf of the lifting and sliding door has always been a difficult and painful point in the sealing of the sliding door. There are many structural methods for the leaf overlap. As long as one of the materials and designs is not up to standard, this part is prone to loose overlap, resulting in poor overall sealing performance of the sliding window. In order to achieve better sealing, the air tightness and the comfortable and smooth operation are weighed and chosen. Either the air tightness is sacrificed to ensure the smooth sliding and pushing of the lifting and sliding door, or the smoothness of the sliding and pushing of the lifting and sliding door is sacrificed to ensure the sealing of the lifting and sliding door. How to ensure air tightness and the smoothness of lifting and sliding use has become a difficulty for lifting and sliding doors.

[0004] To this end, a sliding door anti-theft decorative sealing structure is proposed to ensure the air tightness of the sliding door while improving the smoothness of sliding. Utility Model Content

[0025] 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.

[0026] like Figures 1 to 3 As shown, embodiment 1, a lifting and sliding door anti-theft decorative sealing structure, includes a main body frame 1, a movable fan 2 is installed in the main body frame 1, a sealing structure 3 cooperating with the movable fan 2 is installed on the upper part of the main body frame 1, the movable fan 2 is slidably matched with the main body frame 1, and the upper parts of the indoor and outdoor sides of the movable fan 2 are both in contact with the main frame 1, and a cavity is provided in the middle part of the main body frame 1 to facilitate the lifting of the movable fan 2, the sealing structure 3 is installed in the cavity between the main body frame 1 and the movable fan 2 and seals the cavity to avoid a gap between the movable fan 2 and the main frame 1 that affects the air tightness; the sealing structure 3 includes a base 4 arranged on the upper part of the main body frame 1, a lifting block 5 is movably connected to the base 4, a sealing member 6 is provided between the lifting block 5 and the base 4, and the sealing member 6 connects the base 4 and the lifting block 5, thereby ensuring the sealing performance of the sealing structure 3 between the movable fan 2 and the main frame 1, and the lifting block 5 can move up and down with the movable fan 2, thereby achieving a sealing effect without affecting the movable fan 2 in the lifted state and the non-lifted state.

[0027] Specifically, the sealing structure 3 cooperates with the lifting of the movable fan 2 and the sealing in the normal state. When the movable fan 2 is in the normal state, the lifting block 5 fits with the movable fan 2 but is subjected to a small force, which does not affect the push and pull of the movable fan 2, thereby achieving the sealing when the main frame 1 and the movable fan 2 are slidingly matched. When the movable fan 2 is lifted, the lifting block 5 rises with the movable fan 2, and the movable fan 2 fits with the base 4. At this time, the sealing member 6 is pressed toward the base 4 under the action of the lifting block 5, which does not affect the lifting effect of the movable fan 2, thereby avoiding the problem that the sealing structure at the overlap between the main frame 1 and the movable fan 2 is difficult to ensure both air tightness and push and pull smoothness at the same time.

[0028] In this embodiment, the base 4 includes a fixed frame 4-1, and a track plate 4-2 is provided at the lower part of the fixed frame 4-1. The fixed frame 4-1 and the track plate 4-2 are both installed on the main frame 1. The fixed frame 4-1 is a basic connecting frame, and the track plate 4-2 provides a movable space for the lifting block 5. The lower part of the four corners of the fixed frame 4-1 is fixed with a track plate 4-2, and the middle part of the track plate 4-2 is provided with a track groove 1 that cooperates with the lifting block 5. The track groove 1 limits the range of motion of the lifting block 5, which can prevent the lifting block 5 from shaking and affecting the sealing effect. Both ends of the fixed frame 4-1 are provided with a connecting plate 4-3, and the connecting plate 4-3 and the fixed frame 4-1 are an integrally formed structure. The base 4 is a nylon base. The connecting plate 4-3 includes a trapezoidal portion and a rectangular portion. The rectangular portion is transitionally connected to the fixed frame 4-1 through the trapezoidal portion, and a mounting hole is provided on the rectangular portion. The screw passing through the mounting hole can fix the fixed frame 4-1 on the upper sash frame.

[0029] In this embodiment, at least two sliders 5-1 are provided on the left and right sides of the lifting block 5, and the sliders 5-1 are slidably arranged in the track groove 1. The two ends of the lifting block 5 are restricted in the track groove 1 of the base 4 by the sliders 5-1, and slide up and down along the track 1, which ensures that the nylon block can move up and down while avoiding affecting the sealing between the main frame 1 and the movable fan 2 during the lifting process. The lifting block 5 is a nylon lifting block. The base 4 and the lifting block 5 are both made of nylon material, which ensures the sealing effect of the sealing structure 3, is easy to process and install, is easy to process, has low cost, and has good thermal insulation and sealing effect. Preferably, a positioning card plate is provided at the bottom of the lifting block, and the positioning card plate is located between the front and rear track plates. The positioning card plate is an inverted U-shaped structure. The positioning card plate slides with the movable fan and does not move with the movable fan. The bottom of the positioning card plate is provided with a guide groove that cooperates with the upper flange of the movable fan. The lifting block cooperates with the movable fan through the positioning card plate, which ensures the stability of the lifting block when the movable fan rises. At the same time, the positioning card plate is clamped and cooperated with the movable fan, which also ensures the cooperation between the movable fan and the lifting block during the pushing and pulling process, further ensuring the air tightness of the sealing structure.

[0030] Embodiment 2, a lifting and sliding door anti-theft decorative sealing structure, the sealing member 6 includes a symmetrically arranged sealing strip 1 6-1 and a sealing strip 2 6-2, the upper parts of the sealing strip 1 6-1 and the sealing strip 2 6-2 are correspondingly pasted on the inner wall of the fixed frame 4-1, and the lower parts of the sealing strip 1 6-1 and the sealing strip 2 6-2 are correspondingly pasted on the front and rear sides of the lifting block 5. The sealing strip 1 6-1 and the sealing strip 2 6-2 are pasted between the lifting block 5 and the base 4 to achieve a double-sided connection between the lifting block 5 and the base 4, and realize a double seal between the main frame 1 and the movable sash 2 without affecting the lifting of the movable window. The sealing member 6 is an EPDM sealing strip. The EPDM sealing strip is easy to process, has a good sealing effect, and is low in cost.

[0031] In this embodiment, the main frame 1 includes an outdoor profile 9, an intermediate profile 8 and an indoor profile 7. Insulation strips 10 are installed on both sides of the intermediate profile 8 and are connected to the corresponding outdoor profile 9 and indoor profile 7 through the insulation strips 10. The lower part of the intermediate profile 8 is provided with a track groove 2 that cooperates with the sealing structure 3. The base 4 is installed in the track groove 2. The lifting block 5 forms an insulating cavity with the bottom of the track groove 2 through the side wall of the track groove 2 and the sealing strip 1 6-1, the sealing strip 2 6-2, and the track groove 2, thereby ensuring air tightness while also achieving thermal insulation performance. The middle profile 8 is connected to the indoor profile 7 by using a heat insulation strip 10 and an outdoor profile 9. The heat insulation strip 10 between the indoor profile 7 and the middle profile 8 is located in the upper sliding track of the movable window, which improves the sealing and heat insulation of the sliding door. The indoor profile 7 and the middle profile 8 are both provided with tracks that match the movable fan 2, and the movable fan 2 is dynamically sealed with the indoor profile 7 and the middle profile 8, which ensures the sealing between the movable fan 2 and the main frame 1. The sealing heat insulation component is installed on the track groove 2, and blocks the lifting cavity formed between the main frame 1 and the movable fan 2, which ensures the airtightness and heat insulation between the movable fan 2 and the main frame 1.

[0032] The other structures are the same as those in Example 1.

[0033] Embodiment 3, a lifting and sliding door anti-theft decorative sealing structure, such as Figure 2 As shown, it comprises: a main frame 1 and a movable fan 2, wherein the movable fan 2 is arranged between the main frame 1, and a fixed anti-theft decorative sealing structure 3 is arranged in the middle groove of the main frame 1, such as Figure 1 As shown, the fixed anti-theft decorative sealing structural component 3 includes a fixing component base connected to the main frame 1, and a lifting block and a sealing strip located inside the fixing component base.

[0034] Preferably, if Figure 1As shown, the fixing base of the fixed anti-theft decorative sealing structure 3 is in the shape of a "Z" character, and a lifting block and a sealing strip are arranged inside. The lifting block and the sealing strip are in a flat shape. The fixing base and the lifting block are connected together through an interlaced structure. The lifting block can slide up and down in the connection notch of the fixing base. The upper and lower ends of the sealing strip are fixed to the inner wall of the fixing base and the outer surface of the lifting block by glue. The fixing base and the lifting block are both made of nylon, and the sealing strip is made of EPDM, which is soft, has a large deformation, and a thickness of 0.5~1mm.

[0035] like Figure 2 As shown, the main frame 1 is in a concave shape, and a fixed anti-theft decorative sealing structure 3 can be placed inside the groove. The push-up block falls on the movable fan 2 along the slideway of the fixing base due to its own gravity, and the sealing strip seals the through holes at the front and rear ends of the fixing base, thereby realizing the sealing of the overlap of the lifting and sliding door frame and fan, and ensuring its air tightness.

[0036] When the lift-sliding door is open, the movable leaf 2 will rise 7~8mm, causing the lifting block to rise 7~8mm along the slideway of the fixing base, and the sealing strip will be folded and deformed by 7~8mm under the extrusion of the lifting block and the fixing base. When the lift-sliding door is opened, the movable leaf will rise 7~8mm driven by the lifting mechanism of the lift-sliding door, driving the lifting block to rise 7~8mm accordingly. The contact surface between the lifting block and the movable leaf 2 is small, and the friction is very low, which will not affect the operation of the movable leaf 2.

[0037] Preferably, if Figure 3 As shown, when the lift-and-slide door is closed, the movable leaf 2 will drop 7~8mm, and the lifting block will drop 7~8mm along the slideway of the fixing base due to its own gravity and fall on the movable leaf 2. The sealing strip will be unfolded under the action of the lifting block to seal the through hole of the fixing base. When the lift-and-slide door is closed, the movable leaf 2 will drop 7~8mm, and the lifting block will drop 7~8mm due to its own gravity. The sealing strip will be stretched by the lifting block to seal the through hole of the fixing base, so as to achieve the sealing of the gap between the sliding leaves and ensure the airtightness of the lift-and-slide door.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
