Description

Technical Field

[0001] The utility model relates to the technical field of door and window installation piece development, in particular to a leveling door and window installation connection device. Background Art

[0002] Doors and windows are an indispensable part of house construction. During installation, the door and window frames are usually fixed directly to the wall or the ground with expansion screws. However, due to the thick plaster layer on the walls and the ground during the construction and decoration process, the plaster layer is looser in texture and has weaker structural strength than the concrete structure layer. It cannot bear weight and cannot fix the expansion screws. As a result, the expansion screws cannot be embedded deep enough in the concrete wall or solid ground, resulting in poor installation stability of the door and window frames. At the same time, due to the poor flatness of most walls or ground, the horizontal accuracy of the door and window frame installation is insufficient, resulting in uneven force on the door and window glass during use, resulting in self-explosion.

[0003] To this end, the utility model patent No. 201920919270.0 proposes a door and window installation connecting wall structure, which mainly removes the plaster layer on the installation surface and fills the entire installation surface with a concrete layer formed by a multi-layer mesh structure. Although this technology solves the problem of insufficient door and window installation stability, it has problems such as complex installation structure, long construction time, and high cost. In addition, this technology still has the problem of insufficient horizontal installation accuracy of the door and window frames. Therefore, we urgently need to develop a door and window installation connection structure that can not only ensure the stability and horizontal installation accuracy of door and window installation, but also has a simple structure, quick construction, and is easy to use.

[0008] As a preferred technical solution of the present invention, the top surface of the leveling base plate and the bottom surface of the leveling and height-increasing plate are both provided with multiple leveling platforms of different heights, and an inclined surface is provided between two adjacent leveling platforms of the multiple leveling platforms. After the leveling base plate and the leveling and height-increasing plate are connected, they jointly form a horizontal plate with adjustable thickness.

[0009] As a preferred technical solution of the present invention, an angle a is formed between the inclined surface and the horizontal extension line of the leveling platform, wherein a is 15° to 45°.

[0010] As a preferred technical solution of the present invention, the top surface of the connecting seat is a smooth surface or a toothed surface.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example

[0026] like Figure 1 and Figure 2As shown, the levelable door and window mounting and connection device of the present invention includes a connection base 1 and a mounting plate 2. Specifically, the connection base 1 is installed on concrete after the plaster layer has been removed. The bottom of the connection base 1 is provided with one or more slots 11. In this embodiment, the number of slots 11 is preferably set to two, and the two slots 11 are evenly distributed on the connection base 1. The number of slots 11 can be adjusted according to actual needs. The mounting plate 2 is integrally fixed to the connection base 1. During installation, the mounting plate 2 is fixed to the concrete via multiple expansion screws. During the specific installation, the plaster layer on the wall or the ground is removed according to the width and length of the connecting seat 1, so that an installation groove is formed on the installation surface of the wall or the ground, without removing all the wall plaster layer within the installation range. The connecting seat 1 is placed in the installation groove so that the bottom of the connecting seat 1 is in direct contact with the concrete layer of the wall, and then the mounting plate 2 is fixed to the concrete layer of the wall by multiple expansion screws. In this way, the connecting seat 1 can be firmly fixed on the concrete layer of the wall. This installation method can greatly improve the efficiency of door and window installation and reduce costs.

[0027] In addition, to enhance the fixing effect and strength of the mounting plate 2, a folded edge 8 is provided on the edge of the mounting plate 2. Specifically, the folded edge 8 is integrally fixed to the mounting plate 2. Furthermore, the length and width of the connecting base 1 and the mounting plate 2 can be set according to the specific length and width of the door or window to be installed.

[0028] In order to adjust the level of doors and windows, a leveling structure is provided on the connecting seat 1. Figure 1 As shown, it consists of a leveling base plate 3 and a leveling and heightening plate 4. Specifically, the leveling base plate 3 is mounted on a connecting base 1. The leveling and heightening plate 4 is slidably connected to the leveling base plate 3. The top surface of the leveling base plate 3 and the bottom surface of the leveling and heightening plate 4 are both provided with multiple leveling steps 6 of varying heights. Specifically, the heights of adjacent leveling steps 6 gradually increase or decrease. During installation, the leveling base plate 3 is connected to the leveling and heightening plate 4. When connected, the highest leveling platform 6 of the leveling base plate 3 is docked with the lowest leveling platform 6 of the leveling and heightening plate 4, and the lowest leveling platform 6 of the leveling base plate 3 is docked with the highest leveling platform 6 of the leveling and heightening plate 4, so that each leveling platform 6 of the leveling base plate 3 is docked with the lowest leveling platform 6 of the leveling and heightening plate 4 one by one, so that the leveling base plate 3 and the leveling and heightening plate 4 form a horizontal plate with the same height at both ends after docking. The horizontal plate formed in this embodiment is a rectangular or square plate. In actual production and use, the leveling platforms 6 of the leveling base plate 3 can also be formed into other shapes different from rectangular or square as needed. When in use, the height of the horizontal plate can be adjusted by pushing the leveling and heightening plate 4 to the left or right, such as Figure 1As shown, by pushing the leveling and raising plate 4 to the left, the overall height of the horizontal plate can be increased, and by pushing the leveling and raising plate 4 to the right, the overall height of the horizontal plate can be reduced. The adjustment method can be determined according to the actual setting of the leveling ladder 6 of the leveling base plate 3 and the leveling ladder 6 of the leveling and raising plate 4.

[0029] Among them, the number of leveling platforms 6 can be set according to the needs of actual production use. In this embodiment, the number of leveling platforms 6 is preferably set to six, and the height of each leveling platform 6 can be set according to the needs of actual production use. When the height of each leveling platform 6 is set, the height of the horizontal plate can be fine-tuned.

[0030] In order to facilitate the pushing of the leveling and raising plate 4, an inclined plane 7 is provided between two adjacent leveling platforms 6, and the inclined plane 7 is used to connect the two adjacent leveling platforms 6. Figure 2 As shown, an angle a is formed between the inclined surface 7 and the horizontal extension line of the leveling ladder 6, wherein a is 15° to 45°. The degree of the angle a can be specifically set according to the actual use situation so that the leveling height increasing plate 4 and the leveling base plate 3 can slide well. In this embodiment, the degree of the angle a is preferably set to 30°.

[0031] The top surface of the connecting seat 1 can be set as a smooth surface or a toothed surface. The bottom surface of the leveling base plate 3 and the top surface of the leveling and heightening plate 4 can be set as a smooth surface or a toothed surface. Figure 1 As shown, in order to prevent the leveling base plate 3 from sliding on the connecting seat 1 and to better fix the leveling base plate 3 on the connecting seat 1, so as to ensure that the leveling base plate 3 does not shift when the leveling and height-increasing plate 4 is pushed, thereby ensuring the accuracy and reliability of the height adjustment of the connecting device, this embodiment preferably configures the top surface of the connecting seat 1 and the bottom surface of the leveling base plate 3 as tooth surfaces, wherein the tooth surfaces of the connecting seat 1 and the tooth surfaces of the leveling base plate 3 are two tooth surfaces that can mesh with each other. During installation, the bottom surface of the leveling base plate 3 meshes with the top surface of the connecting seat 1, so that the leveling base plate 3 can be well fixed on the connecting seat 1. When the leveling and height-increasing plate 4 is pushed, the leveling base plate 3 does not shift, thereby ensuring the accuracy and reliability of the height adjustment of the connecting device. At the same time, configuring the top surface of the leveling and height-increasing plate 4 as a tooth surface can improve the stability of the door and window frame installation.

[0032] When used specifically, Figure 3As shown, first, according to the width and length of the connecting base 1, the plaster layer on the wall or ground is removed to form an installation groove on the installation surface of the wall or ground. The number of installation grooves and connecting devices needs to be set according to the specific length of the door and window. After the installation groove is set, the connecting base 1 is placed in the installation groove so that the bottom of the connecting base 1 is in direct contact with the concrete layer of the wall. Then, the mounting plate 2 is fixed to the concrete layer of the wall using multiple expansion screws. Then, the leveling structure is installed on the connecting base 1. After the leveling structure is installed, the door and window frame is placed on the leveling structure. At this time, the overall level of the door and window frame can be adjusted by pushing the leveling and heightening plate 4. After the overall level of the door and window frame is adjusted, the door and window frame is fixed to the connecting base 1 using multiple fixing screws. The fixing screws pass through the door and window frame, the leveling structure, and the top of the connecting base 1 in sequence, and the fixing screws are threadedly connected to the door and window frame, the leveling structure, and the bottom of the connecting base 1. By leveling the height-raising plate 4, the horizontal accuracy of the installed door and window frame can be accurately adjusted to about 0.3 mm, which can make the door and window glass more evenly stressed and effectively reduce the probability of self-explosion of the door and window glass.

[0033] Example 2

[0034] The structure of this embodiment is basically the same as that of embodiment 1, with the difference being that the leveling structure of this embodiment consists of a leveling base plate 3, a leveling and heightening plate 4, and a heightening supplementary plate 5. During specific installation, the leveling base plate 3 is mounted on the connecting seat 1, the leveling and heightening plate 4 is slidably connected to the leveling base plate 3, and the heightening supplementary plate 5 is mounted on the leveling and heightening plate 4. The leveling and heightening plate 4 is used to fine-tune the height of the door and window frames to improve the horizontal accuracy of the installed door and window frames. The heightening supplementary plate 5 can be used to significantly increase the installation height of the door and window frames. In actual use, the thickness of the heightening supplementary plate 5 needs to be set according to actual conditions. It serves as a filling plate to increase the height of the door and window frames, and the number of the heightening supplementary plates 5 can be set as needed.

[0035] Example 3

[0036] The structure of this embodiment is basically the same as that of embodiment 1, except that Figure 4 As shown, the levelable door and window installation connection device also includes a connection seat heightening plate 9. The upper surface of the connection seat heightening plate 9 is provided with a clamping arm 10 that cooperates with the clamping slot 11. The number of clamping arms 10 is the same as the number of clamping slots 11, and in this embodiment, there are two clamping arms 10. When in use, the clamping arm 10 of the connection seat heightening plate 9 is clamped into the clamping slot 11 of the connection seat 1. The connection seat heightening plate 9 is used to significantly increase the height of the levelable door and window installation connection device. That is, when the installation space is too large and the door and window frame needs to be significantly increased, the connection seat heightening plate 9 can be added to the bottom of the connection seat 1 to adjust the overall height of the door and window frame.

[0037] As described above, the present invention can be well implemented.
