Description

TECHNICAL FIELD

[0001] The utility model relates to door and window field, especially a door and window frame structure. BACKGROUND

[0002] At present, when constructing the invisible door, the wall surface paint batch is scraped on the front and back walls of the door frame to form the invisible door frame. In order to reduce the cracking probability of the wall surface paint between the door frame and the wall, the mesh cloth is set to realize the anti-cracking. In order to realize the installation and positioning of the mesh cloth, the clamping strip is fixed on the side of the mesh cloth, and the mesh cloth end is limited on the door frame by the clamping strip, for example, the patent documents disclosed in the Chinese patent authorized publication No. CN215761181U, CN214035279U and CN206928840U. In order to control the use amount of the wall surface paint, the thickness of the wall surface paint batch scraped on the surface of the door frame is generally thin, which easily leads to the small thickness of the clamping strip. This not only easily leads to the limited structure strength of the clamping strip, but also easily leads to the limited fixed connection amount of the clamping strip and the mesh cloth, and easily leads to the inconvenient assembly of the clamping strip and the mesh cloth, thereby easily leading to the limited limiting effect of the clamping strip on the mesh cloth end, and further easily leading to the poor stability and convenience of the installation and positioning of the mesh cloth. This will lead to the limited anti-cracking performance of the mesh cloth. Therefore, it is necessary to design a door and window frame structure to solve the above technical problems. SUMMARY

[0003] The utility model aims at solving the above problems and deficiencies, and provides a door and window frame structure. The door and window frame structure not only can improve the installation and positioning efficiency of the anti-cracking surface material for preventing the cracking of the wall surface paint layer, but also can play a very stable and reliable positioning effect on the end of the anti-cracking surface material, thereby can improve the convenience, stability and reliability of the installation and positioning of the anti-cracking surface material, and further can improve the anti-cracking performance of the wall. Such door and window frame structure can have very high reliability and applicability.

[0004] The technical scheme of the utility model is realized as follows:

[0005] A door and window frame structure, characterized in that it comprises an invisible frame, at least one clamping groove is formed on the batch scraping surface of the invisible frame, and a clamping strip is embedded in the clamping groove.

[0009] Preferably, a receiving groove is formed on the corner of the wall-joining surface of the invisible frame.

[0010] Preferably, at least one side wall of the clamping strip is provided with an anti-skid surface.

[0011] Preferably, the door and window frame structure further comprises a crack-preventing surface material capable of preventing the wall surface paint from cracking, and the end of the crack-preventing surface material is embedded in the clamping groove, so that the end of the crack-preventing surface material is clamped by the clamping strip and the groove wall of the clamping groove.

[0012] Preferably, the clamping strip is a hard plastic strip or a metal strip.

[0013] Preferably, at least one beveled groove is formed on the batch scraping surface.

[0014] Preferably, the invisible frame is a profile frame, and the batch scraping surface and the clamping groove are formed integrally with the invisible frame.

This not only allows the clamping groove to accommodate the end of the crack-preventing surface material, but also allows the clamping strip to be embedded in the clamping groove, thereby quickly and stably clamping and positioning the end of the crack-preventing surface material. This improves the positioning efficiency of the crack-preventing surface material and stably and reliably positions the end of the crack-preventing surface material.

[0024] As Figures 1 to 3 The utility model discloses a door and window frame structure, including invisible frame 1, the batch scraping surface 11 of invisible frame 1 is seted up at least one clamping groove 12, the clamping groove 12 is embedded with embedding strip 2.

[0025] On this door and window frame structure, at least one clamping groove 12 is seted up on the batch scraping surface 11 of invisible frame 1, and embedding strip 2 is embedded in the clamping groove 12. This not only can utilize clamping groove 12 to contain the end of anti-cracking surface material, but also can utilize embedding strip 2 to be embedded into clamping groove 12, to realize very stable and reliable clamping positioning of the end of anti-cracking surface material quickly and stably, which can improve the positioning efficiency of anti-cracking surface material and provide very stable and reliable positioning of the end of anti-cracking surface material. The door and window frame structure can improve the convenience, stability and reliability of anti-cracking surface material positioning, thereby improving the anti-cracking performance of the wall surface. Therefore, such door and window frame structure can have very high reliability and applicability.

[0026] Meanwhile, by using the above structure, embedding strip 2 and anti-cracking surface material can have a split structure, and different types of anti-cracking surface material can be arbitrarily replaced according to the stability of the wall surface. For example, the anti-cracking surface material can be kraft paper, mesh cloth or special cloth that can prevent the cracking of the wall surface coating layer. In this way, embedding strip 2 and invisible frame 1 can be clamped on different positions of the anti-cracking surface material to ensure that the anti-cracking surface material is effectively stretched and different widths of anti-cracking surface material can be conveniently set, thereby facilitating the use in more environments, and the applicability of the door and window frame structure is very strong.

[0027] The clamping groove 12 and embedding strip 2 of the door and window frame structure can be used not only for clamping and positioning anti-cracking surface material, but also for clamping and positioning other mesh surface anti-cracking accessories that can prevent the cracking of the wall surface coating layer. Therefore, the door and window frame structure can have very high applicability.

[0028] As Figure 4As shown in the drawings, at least one side wall of the embedded strip 2 is provided with an anti-skid surface 21. The anti-skid surface 21 can be used to enhance the restriction of the anti-cracking surface material, thereby further improving the stability and reliability of the installation and positioning of the anti-cracking surface material.

[0029] As shown in the drawings, Figure 4 The anti-skid surface 21 can be a corrugated anti-skid surface, a tooth-shaped anti-skid surface, or a net-shaped anti-skid surface, etc., which can play a good anti-skid role.

[0030] As shown in the drawings, Figure 4 At least one corner of the inner wall of the embedded strip 2 is provided with a guide inclined surface 22. In this way, when the embedded strip 2 is embedded, the guide inclined surface 22 can be used to guide the embedded strip 2, thereby facilitating the embedded strip 2 to enter the clamping groove 12 more smoothly, and further improving the convenience of assembly.

[0031] As shown in the drawings, Figures 1 to 4 The slot of the clamping groove 12 is a V-shaped slot 121, the outer end of the embedded strip 2 is a reversed trapezoidal portion 23 matched with the V-shaped slot 121, and the reversed trapezoidal portion 23 is embedded in the V-shaped slot 121. This not only increases the clamping amount of the anti-cracking surface material, but also increases the structural strength and positioning capacity of the embedded strip 2, and enables the anti-cracking surface material to be placed in the clamping groove 12 in an inclined state, which can facilitate the anti-cracking surface material to be positioned more stably and reliably, thereby further improving the reliability and applicability of the door and window frame structure.

[0032] As shown in the drawings, Figure 2 As shown in the drawings, Figure 3 The reference convex strip 14 is provided on the side away from the wall surface 13 of the invisible frame 1. The side wall of the reference convex strip 14 close to the batch scraping surface 11 is an inclined surface 141 inclined away from the batch scraping surface 11. At least one receiving groove 142 is formed on the inclined surface 141. The reference convex strip 14 can be used as a thickness reference for wall surface paint batching, which can improve the accuracy and convenience of wall surface paint batching. The inclined surface 141 not only controls the width of the reference convex strip 14, but also ensures that the reference convex strip 14 has high structural strength, which can gradually thicken the wall surface paint layer while ensuring that the reference convex strip 14 can play a very stable and reliable positioning and restriction role. The receiving groove 142 can be used to store wall surface paint, thereby improving the adhesion of wall surface paint on the inclined surface 141, and further facilitating the construction of more stable and reliable invisible doors and windows.

[0033] As shown in the drawings, Figure 3As shown, the inclined surface 141 is in the same plane with the corresponding wall of the V-shaped opening 121, which not only facilitates the molding process, but also helps to build a narrow frame structure, thereby helping to improve the scope of application. The receiving groove 142 is also provided on the wall of the V-shaped opening 121 adjacent to the inclined surface 141, which can enhance the storage capacity of the wall paint, thereby enhancing the adhesion of the wall paint, and further improving the reliability of the door and window frame structure.

[0034] As shown in the drawings, Figure 2 With Figure 3 As shown, the corner of the wall-adjacent surface 13 of the invisible frame 1 is provided with a receiving groove 15. The receiving groove 15 can be used to store wall paint, so that more amount of wall paint can be stored between the invisible frame 1 and the wall, thereby facilitating the formation of a more stable and reliable adhesion effect of the wall paint, and further improving the reliability and applicability of the door and window frame structure. The receiving groove 15 is provided on the corner of the wall-adjacent surface 13, which can be used to achieve the positioning of the invisible frame 1 by embedding and connecting other auxiliary positioning members with the receiving groove 15 during the installation of the invisible frame 1, which can facilitate the enhancement of the stability of the installation and positioning of the invisible frame 1 according to the needs.

[0035] As shown in the drawings, Figure 5 With Figure 6 As shown, the door and window frame structure further comprises a crack-resistant surface material 3 for preventing the wall paint from cracking, the end of the crack-resistant surface material 3 is embedded in the clamping groove 12, and the end of the crack-resistant surface material 3 is clamped by the groove wall of the clamping groove 12 and the clamping strip 2. This can facilitate the quick and stable positioning of the end of the crack-resistant surface material 3, thereby further improving the stability and reliability of the installation and positioning of the crack-resistant surface material 3, and further improving the crack-resistant performance.

[0036] As shown in the drawings, Figure 5 With Figure 6 As shown, during the installation of the crack-resistant surface material 3, the end of the crack-resistant surface material 3 is first overlapped on the slot of the clamping groove 12; then the clamping strip 2 is embedded into the clamping groove 12, which pushes the crack-resistant surface material 3 to move into the clamping groove 12, so that the end of the crack-resistant surface material 3 can be clamped by the two side walls of the clamping strip 2 and the groove wall of the clamping groove 12, and the inner end surface of the clamping strip 2 and the groove bottom of the clamping groove 12. This not only enables the clamping strip 2 to quickly clamp the end of the crack-resistant surface material 3, but also ensures that the clamping action is extremely stable and reliable, thereby stably positioning the crack-resistant surface material 3.

[0037] The crack-resistant surface material 3 is a crack-resistant cloth, kraft paper or mesh cloth, which can be used to prevent the wall paint from cracking.

[0038] As shown in the drawings, Figure 2As shown, the batch scraping surface 11 is provided with at least one beveled slot 16. The beveled slot 16 can not only be used for accommodating the wall paint, but also can help to stably and reliably limit the wall paint, so as to effectively enhance the adhesion of the wall paint, and further improve the reliability and applicability of the door and window frame structure.

[0039] As shown in Figure 2 , the beveled slot 16 can avoid the slot directly facing the back or front, so as to better limit the wall paint. In actual opening, the beveled slot 16 can be made into a parallelogram or other beveled slot, which can meet the actual manufacturing and use requirements.

[0040] As shown in Figure 2 , when the width of the batch scraping surface 11 is slightly narrow, the beveled slot 16 can not be provided. When the width of the batch scraping surface 11 is slightly wide, the beveled slot 16 can be provided to enhance the adhesion of the wall paint, which can ensure the high batch scraping quality of the wall paint.

[0041] The embedded strip 2 is a hard plastic strip or a metal strip. The hard plastic strip can not only make the embedded strip 2 have a high-strength and easy-to-manufacture structure, but also can still meet the installation and positioning requirements when being tightly embedded, and can make the embedded strip 2 play a stable and reliable positioning role on the anti-cracking surface material 3, which helps to further improve the reliability and applicability of the door and window frame structure. The metal strip can have high structural strength, so as to have a high-strength clamping effect on the end of the anti-cracking surface material 3, which helps to further improve the reliability and applicability of the door and window frame structure.

[0042] In the actual manufacturing process, the embedded strip 2 can be a hard plastic strip made of PVC or a metal strip made of aluminum profile, which can meet the actual manufacturing and use requirements. Of course, the utility model can also be other hard plastic strips or metal strips to constitute the embedded strip 2, which is not limited to the hard plastic strip made of PVC or the metal strip made of aluminum profile. Other hard plastic strips or metal strips to constitute the embedded strip 2 are also within the protection scope of the utility model.

[0043] As shown in Figure 2 , the invisible frame 1 is a profile frame, and the batch scraping surface 11 and the clamping slot 12 are integrally formed with the invisible frame 1. This not only can make the invisible frame 1 have high structural strength, but also can improve the efficiency of batch manufacturing the invisible frame 1, thereby helping to further improve the reliability and applicability of the door and window frame structure.

[0044] As shown in Figure 2As shown, the invisible frame 1 is a hollow profile frame. This not only facilitates the lock installation and hiding, but also facilitates the hiding of the screws for fixing the invisible frame 1 to the wall, thereby helping to further improve the applicability of the door and window frame structure.

[0045] As Figure 2 With Figure 4 As shown, a clamping groove 12 is formed on each of the front and rear of the batch scraping surface 11 of the invisible frame 1, and a door blocking strip 18 is arranged on the side of the door connecting surface 17 of the invisible frame 1. When the batch scraping surface 11 on the front or rear side of the invisible frame 1 is widened, a beveled slot 16 is formed on the widened batch scraping surface 11. When the invisible frame 1 is a hollow profile frame, the batch scraping surface 11, the clamping groove 12, the V-shaped slot 121, the wall connecting surface 13, the reference convex strip 14, the inclined surface 141, the receiving groove 142, the receiving groove 15, the beveled slot 16, the door connecting surface 17, and the door blocking strip 18 are integrally formed with the invisible frame 1. The embedded clamping strip 2 is also a profile strip, and the anti-skid surface 21, the guide inclined surface 22, and the inverted trapezoidal portion 23 are integrally formed with the embedded clamping strip 2. This not only greatly improves the manufacturing efficiency, but also improves the reliability of the structure.

[0046] As Figure 7 With Figure 8 As shown, when the wall paint layer 100 is batch scraped on the batch scraping surface 11, the wall paint layer 100 covers the batch scraping surface 11, and the wall paint layer 100 also covers the anti-cracking surface material 3. This can effectively prevent the wall paint layer 100 from cracking.

[0047] The above embodiments are preferred embodiments of the present application, and any similar structure and equivalent changes made should be within the protection scope of the present application.
