Description

Technical Field

[0001] The utility model relates to the technical field of the structural improvement design of assembled glass profiles for doors and windows, and particularly relates to a split pressing strip profile structure for swing doors and windows. Background Art

[0002] The pressing strip of aluminum alloy doors and windows is used to fix the glass, making the glass installation firm and safe. Generally, rubber strips or glass glue are selected to connect the pressing strip and the glass, providing sealing and supporting functions, so as to improve the sealing performance, wind pressure resistance of the doors and windows and pursue beauty on this basis. The common pressing strips on the market are assembled at 45 degrees. Its installation method is relatively complex. It needs to be cut obliquely and assembled before installation, which has relatively high technical requirements for construction workers. The overall effect is relatively delicate, and the gap will not be noticed if not looked at carefully.

[0003] The profile design, adjustment of the door and window processing technology, and installation operation have a significant impact on the appearance and performance of the doors and windows. Since the frame materials are assembled first and then the glass and pressing strips are installed, the flatness and twist of the overall frame materials are prone to deformation during the production process of the pressing strip profiles, resulting in situations such as loose, tight, unable to be buckled in, or uneven when assembling the pressing strips. Since the pressing strip profile is an easily deformable profile, it is difficult to control the assembly dimensions. When the pressing strip is closed, the pressing strip is easy to loosen and slip out, and cannot clamp the glass tightly, as Figure 5 shown. When the pressing strip opens, due to the large elasticity and small clamping amount of the pressing strip, the pressing strip is easy to pop out by itself and cannot clamp the glass tightly; if the clamping amount of the pressing strip is large, it is difficult to buckle the pressing strip into the card slot, as Figure 6 shown. In addition, the 45-degree corner pressing strip with edges is prone to deformation during production and transportation, which is difficult to control. After installation, either the appearance does not meet the standard, or the assembly effect does not meet the standard, or it is deformed and difficult to install or cannot be installed. There are the following situations: the cantilever at the buckling position is relatively long, and it is extremely easy to retract during production and transportation, which leads to poor assembly or inability to buckle and fall off of the pressing strip; the tail edge part is easy to retract, expand or bend during production and transportation, resulting in poor splicing or inability to splice; the vertical edge of the pressing strip is also easy to retract or expand, resulting in poor assembly or inability to buckle and fall off of the pressing strip, and poor splicing or inability to splice, as Figures 7 - 8 shown.

[0004] In the prior art, a patent with the publication number CN209444083U discloses a split aluminum window pressing strip structure, including a stepped base, an L-shaped decorative pressing strip, and a U-shaped inner and outer beveled tooth rubber strip. The base is provided with tooth ribs, and the decorative pressing strip is provided with reverse beveled tooth grooves; the decorative pressing strip and the base are fixed to each other by beveled teeth through the inner and outer beveled tooth rubber strip. The L-shaped corner code cavity enables the pressing strip to be cut at 45° and pushed into the frame, and at the same time, the pressing strip is fixed to the window frame by using the tooth ribs and the silicone groove of the base, avoiding the use of screws for fixing. The split pressing strip used in the present utility model has the advantages of a flat and beautiful appearance and no need for screwing during installation.

[0005] In the above technical solution, it is necessary to put the inner and outer beveled tooth rubber strip into the second tooth rib of the base, and the reverse beveled tooth groove on the decorative pressing strip is sleeved on the outer surface of the inner and outer beveled tooth rubber strip, so as to fix the decorative pressing strip frame, and the overall assembly structure is relatively complex.

[0006] In order to solve one of the above problems, the present application provides a split profile structure for the pressing strip of a flat-opening door and window. Utility Model Content

The ends of the fourth buckle and the hook plate are clamped in the slot of the frame profile;

[0009] A buckle cover, the buckle cover includes a second side plate and a fourth buckle and a fifth buckle formed by the horizontal extension of the second side plate. The fourth buckle and the fifth buckle can be snap-connected to the first buckle and the second buckle respectively to complete the assembly of the buckle cover and the first decorative pressing strip.

[0010] Further, the slot of the frame profile as described above is composed of a first buckle position and a second buckle position arranged oppositely.

[0011] Further, the first side plate as described above abuts against the first buckle position and makes the third buckle catch the first buckle position.

[0012] Further, the protrusions on the first buckle and the second buckle as described above are arranged in opposite directions.

[0013] Further, the first side plate as described above is perpendicular to the first support plate, and the extending directions of the first buckle and the second buckle are parallel to the first support plate.

[0014] Further, the third buckle as described above is formed by extending in a right-angle bending manner.

[0015] Further, the protrusion on the third buckle as described above faces the first buckle position.

[0016] Further, one end of the hook plate as described above is perpendicular to the first support plate, and the other end of the hook plate is bent to form a hook.

[0033] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0034] Embodiment 1

[0035] Referring to Figures 1 - 4 As shown, a split flush door and window press strip profile structure of the present utility model, the press strip profile is snap-connected to the frame profile 3 of the flush door and window, including a first decorative press strip 1. The first decorative press strip 1 includes a support plate 15, the support plate 15 is a straight plate in the horizontal direction, one end of the support plate 15 extends vertically to form a first side plate 11, the first side plate 11 is a straight plate in the vertical direction, a first buckle 12 and a second buckle 13 are formed by horizontal extension on one side of the first side plate 11, and a fourth buckle 22 is formed by vertical extension on the other side of the first side plate 11. The other end of the support plate 15 extends vertically to form a hook plate 16. The ends of the fourth buckle 22 and the hook plate 16 are clamped in the slot of the frame profile 3, as Figure 4 shown, the slot of the frame profile 3 is composed of a first buckle position 32 and a second buckle position 33 arranged oppositely. Specifically, the fourth buckle 22 is snap-connected to the first buckle position 32 while the end of the hook plate 16 is clamped at the second buckle position 33;

[0036] A buckle cover 2, the buckle cover 2 includes a second side plate 21 and a fourth buckle 22 and a fifth buckle 23 formed by horizontal extension of the second side plate 21. The second side plate 21 is also a straight plate in the vertical direction. The fourth buckle 22 and the fifth buckle 23 can be snap-connected to the first buckle 12 and the second buckle 13 respectively to complete the assembly of the buckle cover 2 and the first decorative press strip 1.

[0037] Both the first decorative press strip 1 and the buckle cover 2 are profiles formed by integral processing, generally aluminum profiles or aluminum alloy profiles. The tolerance fit in the above snap-connection method is designed according to the conventional design.

[0038] The installation method of the split-type first decorative pressing strip 1 and the buckle cover 2 of the present application on the frame profile 3 is as follows: First, measure and cut the length and angle of the first decorative pressing strip 1 to be installed to ensure that the length and angle of the first decorative pressing strip 1 are suitable. Note that the cutting angle should be appropriate for subsequent splicing. Then, install the glass, and then install the cut first decorative pressing strip 1 in the corresponding positions in sequence, press the glass tightly, and spray special glue at the splicing joints for bonding. During this process, it is necessary to ensure that all four sides of the first decorative pressing strip 1 are clamped with the frame profile 3 and the glass is clamped tightly. Finally, install the buckle cover 2 with the cut angle in sequence on the corresponding first decorative pressing strip 1 to ensure a good 45-degree splicing effect, and spray special glue at the splicing joints for bonding.

[0039] Embodiment 2

[0040] Refer to Figures 1 - 4 As shown, on the basis of the technical solution of Embodiment 1, a split-type flat door and window pressing strip profile structure, as Figure 2 shown, for the specific structure of the first decorative pressing strip 1, the first side plate 11 abuts against the first buckle position 32 and the third buckle head 14 clamps the first buckle position 32. The first buckle position 32 is formed by the horizontal extension of the main body part of the frame profile 3, and the third buckle head 14 is formed by extending in a right-angle bending manner. The protrusion on the third buckle head 14 faces the first buckle position 32, that is, the lower part of the first side plate 11 extends out the bent third buckle head 14. In this way, when assembling the first decorative pressing strip 1 with the frame profile 3, it is necessary to simultaneously satisfy that the end of the first side plate 11 abuts against the first buckle position 32 and the third buckle head 14 clamps the first buckle position 32.

[0041] Furthermore, the protrusions on the first buckle head 12 and the second buckle head 13 are arranged in opposite directions to facilitate the mutual clamping with the two buckle heads on the buckle cover 2 to prevent loosening and falling off. In addition, the first side plate 11 is perpendicular to the first support plate 15, and the extending directions of the first buckle head 12 and the second buckle head 13 are parallel to the first support plate 15.

[0042] Embodiment 3

[0043] Refer to Figures 1 - 4 As shown, on the basis of the technical solution of Embodiment 1, a split-type flat door and window pressing strip profile structure, as Figure 2 shown, for the specific structure of the first decorative pressing strip 1, one end of the hook plate 16 is perpendicular to the first support plate 15, and the other end of the hook plate 16 is bent to form a hook. In this way, when assembling the first decorative pressing strip 1 with the frame profile 3, while satisfying the clamping of the first buckle position 32, it is also necessary to make the first side plate 11 abut against the first buckle position 32 and the hook abut against the second buckle position 33.

[0044] Further, the extending directions of the fourth buckle 22 and the fifth buckle 23 are perpendicular to the second side plate 21, the protrusions on the fourth buckle 22 and the first buckle 12 are arranged in opposite directions, and the protrusions on the fifth buckle 23 and the second buckle 13 are arranged in opposite directions. The design directions of the protrusions on the above-mentioned buckles are to facilitate the mutual clamping with the two buckles on the buckle cover 2, so as to prevent the buckle cover 2 from loosening and falling off during use after buckling the first decorative pressing strip 1.

[0045] As Figures 5 - 8 shown, the existing structural method has the following deficiencies in operation:

[0046] First, profile extrusion belongs to hot processing, and the second decorative pressing strip 4 profile is an easily deformable profile. The integral design makes it difficult to control the assembly dimensions. When the second decorative pressing strip 4 is closed, the second decorative pressing strip 4 is prone to looseness and slipping out, and cannot clamp the glass tightly, as Figure 5 shown; when the second decorative pressing strip 4 is open, due to the large elasticity and small clamping amount of the second decorative pressing strip 4, the second decorative pressing strip 4 is prone to pop out by itself and cannot clamp the glass tightly; if the clamping amount of the second decorative pressing strip 4 is large, it is difficult to buckle the second decorative pressing strip 4 into the card slot, as Figure 6 shown.

[0047] Second, due to the dimensional tolerance of the aluminum alloy product, the second decorative pressing strip 4 cannot fit perfectly when buckled on the frame and sash, and there will be situations such as large gaps at the splicing positions or height differences of the second decorative pressing strip 4, the appearance surface is uneven, or it cannot be assembled.

[0048] Third, the second decorative pressing strip 4 is cut at a 45-degree angle, and it cannot be cut by a hand saw. If the cut angle is slightly deviated, it cannot be assembled.

[0049] Fourth, when processing the 45-degree corner group angle second decorative pressing strip 4 with edges, it is prone to deformation during the production and transportation process, which is difficult to control. After installation, either the appearance does not meet the standard, or the assembly effect does not meet the standard, or it is deformed and difficult to install or cannot be installed. It affects the progress of the project / engineering and delays the delivery date. For example: the cantilever at the buckling position is relatively long, and it is extremely prone to inward contraction during the production and transportation process, which results in poor assembly of the pressing strip or inability to buckle and fall off; the tail edge part is prone to inward contraction, outward expansion or bending during the production and transportation process, resulting in poor splicing or inability to splice; the vertical edge of the second decorative pressing strip 4 is also prone to inward contraction or outward expansion, resulting in poor assembly of the pressing strip or inability to buckle and fall off, poor splicing or inability to splice, as Figures 7 - 8 shown.

[0050] In the device of the present utility model, the assembly and cooperation relationships of various components are involved. The common auxiliary materials required during the processing and installation of profiles are existing technologies or materials. Those skilled in the art can directly purchase or customize them according to the required product models and specifications.

[0051] The above are only the preferred specific embodiments of the present utility model, and common general knowledge such as the specific structures and characteristics in the solution are not described in detail herein. For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. Any person skilled in the technical field, within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present utility model.
