[0028] Example 1

[0029] The adjustable wood-plastic door frame provided in this embodiment includes two cardboard structures 1 symmetrically arranged on both sides of a wall a, and a plurality of telescopic connection structures 2 arranged between the two cardboard structures 1.

[0030] In this embodiment, the card plate structure 1 includes a panel 101 parallel to the long side of the wall a, a connecting plate 102 arranged on the panel 101 and parallel to the wide side of the wall a, an internal threaded hole 103 arranged at the end of the connecting plate 102 and used to connect with the adjusting screw 202, and a step surface 104 arranged at the connection between the panel 101 and the connecting plate 102.

[0031] The panel 101, connecting plate 102, and stepped surface 104 are all made of wood-plastic and are integrally molded, forming a T-shaped structure. The length of the internal threaded hole 103 is less than half the length of the connecting plate 102 to ensure the overall strength of the connecting plate 102. The stepped surface 104 is a frame protruding from the periphery of the connecting plate 102. In this embodiment, it serves to strengthen the connection between the panel 101 and the connecting plate 102.

[0032] In this embodiment, the telescopic connection structure 2 includes an internal threaded sleeve 201 and an adjusting screw 202 with one end screwed into the internal threaded sleeve 201 and the other end connected to the clamping plate structure 1 .

[0033] There are two adjusting screws 202, one mounted on each side of the internally threaded sleeve 201, so that both ends of the internally threaded sleeve 201 are connected to the two clamping plate structures 1. Since the adjusting screws 202 can adjust the distance between the clamping plate structure 1 and the internally threaded sleeve 201 by screwing the depth of the adjusting screws 202 into the internally threaded sleeve 201, the distance between the two clamping plate structures 1 can be adjusted according to the thickness of the wall.

[0034] As a further preference of this embodiment, the telescopic connection structure 2 also includes a countersunk hole 206 arranged at the opening of the internal threaded hole 103, a limiting nut 207 threaded on the adjusting screw 202 and screwed into the countersunk hole 206, and a partition 208 arranged in the middle of the inner cavity of the internal threaded sleeve 201.

[0035] Among them, the structural setting of the countersunk hole 206 and the limiting nut 207 is used to ensure that the adjusting screw 202 is fixed after the depth of the end of the adjusting screw 202 screwed into the internal threaded hole 103 is determined, so as to avoid the position of the adjusting screw 202 in the internal threaded hole 103 from changing; the purpose of setting the partition 208 is to avoid the depth difference between the two adjusting screws 202 screwed into the internal threaded sleeve 201 being too large, thereby resulting in a large difference in the connection strength between the internal threaded sleeve 201 and the two clamping plate structures 1, affecting the overall stability of the door frame.

[0036] In this embodiment, the gaps between the clip structure 1 and the telescopic connection structure 2 and the wall a are filled with an adhesive foam layer. After the clip structure 1 and the telescopic connection structure 2 are connected, the gaps between them and the wall a are filled to form an adhesive foam layer, thus completing the connection between the door frame and the wall a. The materials used to form the adhesive foam layer are commonly used in the art and will not be described in detail in this embodiment.

[0037] The adjustable wood-plastic door frame provided in this embodiment can be flexibly adjusted according to the thickness of the wall. The adjustment structure is located inside the door frame structure, and the door frame surface is flat and beautiful. At the same time, the adjustment structure is composed of a simple sleeve and a connecting rod, which has the advantages of simple structure and easy maintenance.

[0038] Example 2

[0039] This embodiment adds a cover plate 3 for shielding the telescopic connection structure 2 on the basis of embodiment 1. The specific structure is as follows:

[0040] The door frame also includes a cover plate 3 disposed between the two clip structures 1. The ends of the cover plate 3 engage with the stepped surfaces 104 of the two clip structures 1. Two chamfered surfaces 301 are provided on the sides of the cover plate 3 near the stepped surfaces 104. A positioning rod 302 is provided on the surface of the cover plate 3 near the wall a, and a slot 203 is provided on the internally threaded sleeve 201 to mate with the positioning rod 302.

[0041] Among them, the purpose of setting the beveled surface 301 is to improve the stability and tightness of the connection between the cover plate 3 and the step surface 104, and to ensure that the exposed door frame surface is beautiful; the connection function of the slot 203 and the positioning rod 302 is to improve the installation stability of the cover plate 3, and the second function is to prevent the internal threaded sleeve 201 from rotating after the cover plate 3 is installed, thereby changing the distance between the two clamping plate structures 1.

[0042] Example 3

[0043] This embodiment optimizes the telescopic connection structure 2 based on the embodiment 1 or embodiment 2, specifically as follows:

[0044] The telescopic connection structure 2 further includes two connecting screw holes 204 provided on the upper and lower surfaces of the internally threaded sleeve 201 , and a connecting screw 205 with both ends threadedly connected to the two connecting screw holes 204 is provided between two adjacent internally threaded sleeves 201 .

[0045] During the installation process of a door frame, at least three telescopic connection structures 2 are required to be respectively arranged at the upper, middle and lower positions to strengthen the connection stability between the two card structures 1; the connecting screws 205 are used to complete the series connection between the telescopic connection structures 2, so that the above-mentioned multiple telescopic connection structures 2 are located in the same vertical plane, thereby improving the integrity of the telescopic connection structure 2 and ultimately strengthening the installation strength of the door frame.

[0046] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
