The fixed profile includes a first profile section 6, a second profile section 7, and a third profile section 8 arranged from back to front and fixed to each other. A first receiving groove 9 with an opening facing away from the wall is formed between the first profile section 6, the second profile section 7, and the third profile section 8. The first receiving groove 9 can accommodate the end of a fastener 10. The baffle 5 is embedded in the groove of the first receiving groove 9. The inner side of the first profile section 6 is provided with a support for... The supporting surface of the hinge plate 11 is flush with the inner side of the baffle 5. The rear side of the first profile part 6 is provided with a first mounting groove 12, and the front side of the third profile part 8 is provided with a second mounting groove 13. The first movable profile 3 and the second movable profile 4 are both L-shaped structures. One side of the first movable profile 3 is slidably connected in the first mounting groove 12, and one side of the second movable profile 4 is tightly fitted in the second mounting groove 13. The other side of the first movable profile 3 and the other side of the second movable profile 4 are respectively attached to the opposite sides of the wall.

[0026] With the above settings, firstly, the distance between the first movable profile 3 and the second movable profile 4 is adjustable to accommodate walls of different thicknesses; secondly, the inner side of the baffle 5 is flush with the support surface, and the baffle 5 will not interfere with the hinge plate 11, making it convenient to adjust the hinge plate 11 back and forth to accommodate door panels of different thicknesses; thirdly, the baffle 5 covers the fastener 10 to hide the fastener 10 and improve aesthetics.

[0027] The fixed profile, the first movable profile 3, and the second movable profile 4 are all integrally molded polyvinyl chloride structures, manufactured by extrusion process; Figure 1The markings indicate the front and rear sides and the inner and outer sides of the door frame profile. The inner side refers to the side of the door frame profile facing away from the wall, and the outer side refers to the side of the door frame profile facing the wall. The first movable profile 3 has an L-shaped cross-section. One side of the first profile portion 6 extends forward and into the first mounting groove 12, while the other side extends outward for easy attachment to the wall. One side of the second profile portion 7 extends backward and fits snugly into the second mounting groove 13, while the other side extends outward for easy attachment to the wall. By controlling the depth of the first movable profile 3 in the first mounting groove 12 and the depth of the second movable profile 4 in the second mounting groove 13, the distance between the first movable profile 3 and the second movable profile 4 can be adjusted to accommodate walls of different thicknesses. The door frame profile is then installed. First, the expansion sleeve of the expansion screw is driven into the wall end face. One side of the second movable profile 4 is pressed into the second mounting groove 13. Then, the fixed profile is attached to the wall end face. Next, one side of the first movable profile 3 is inserted into the first mounting groove 12. The first movable profile 3 and the second movable profile 4 are attached to opposite sides of the wall. The expansion screw is a self-tapping screw. The self-tapping screw passes through the second profile part 7 and engages with the expansion sleeve on the wall end face to fix the fixed profile to the wall. The baffle 5 is installed into the groove of the first receiving groove 9 to cover the self-tapping screw. The hinge plate 11 is attached to the support surface. Another self-tapping screw passes through the hinge plate 11, the first profile part 6, and the first movable profile 3, and engages with the expansion sleeve on the wall end face. Figure 3 The self-tapping screws lock the hinge plate 11 to the support surface and also lock the fixing profile to the end face of the wall 19. At this point, the door frame profile installation is complete. Finally, the door leaf 20 is installed on the hinge plate 11.

[0028] As one implementation method, the fixed profile has a multi-cavity structure. Two ribs 14 are provided on the inner wall of the second profile part 7 near the baffle 5. The two ribs 14 are arranged in a front-to-back manner, and the distance between the two ribs 14 is adapted to the outer diameter of the fastener 10.

[0029] With the above settings, firstly, the cross-sectional area of ​​the fixed profile is reduced, saving raw materials; secondly, the rib 14 increases the rigidity of the inner wall of the second profile section 7, preventing deformation of the second profile section 7.

[0030] The self-tapping screw of the expansion screw of this application passes between two ribs 14. The ribs 14 enhance the rigidity of the inner wall of the second profile 7. When tightening the self-tapping screw, the end of the self-tapping screw may press against the inner side of the second profile 7. The ribs 14 can prevent the inner side of the second profile 7 from deforming.

[0031] As one implementation method, both the first movable profile 3 and the second movable profile 4 are multi-cavity structures.

[0032] The above settings reduce the material consumption of the first movable profile 3 and the second movable profile 4.

[0033] As one implementation, the inner side of the third profile section 8 protrudes from the inner side of the baffle 5, and a third mounting groove 15 is provided on the rear side of the third profile section 8, with the groove opening of the third mounting groove 15 being narrowed.

[0034] The above setup facilitates the installation of rubber strips, thereby improving the sealing and sound insulation between the door leaf and the door frame.

[0035] Specifically, one side of the rubber strip is adapted to the third mounting groove 15. The rubber strip has good elasticity. After being embedded in the third mounting groove 15, the rubber strip is not easy to detach from the third mounting groove 15. The other side of the rubber strip protrudes from the rear side of the third profile part 8. After the door is closed, the door squeezes the rubber strip to improve the sealing and sound insulation between the door and the door frame profile.

[0036] As one implementation, the groove of the third mounting slot 15 is fitted with a sticker 16.

[0037] The above settings prevent foreign objects from entering the third mounting slot 15.

[0038] When no rubber strip is installed in the third mounting slot 15, the sticker 16 is affixed to the opening of the third mounting slot 15 to prevent foreign objects from entering the third mounting slot 15. When the rubber strip needs to be installed, the sticker 16 is peeled off and then the rubber strip is installed.

[0039] As one implementation, the first receiving groove 9 is provided with limiting ribs 17 on the inner walls of opposite sides. The baffle 5 includes a baffle body 51 and two elastic members 52 integrally formed on the outside of the baffle body 51. The inner side of the baffle body 51 is flush with the support surface. A locking head 53 is provided on the side of the elastic member 52 away from the other elastic member 52. A guide surface 54 is provided on the side of the locking head 53 away from the baffle body 51. The side of the locking head 53 away from the guide surface 54 abuts against the side of the limiting rib 17 away from the baffle body 51.

[0040] The above configuration facilitates the insertion of the baffle 5 into the first receiving slot 9.

[0041] When installing the baffle 5, the elastic element 52 of the baffle 5 is aligned with the first receiving groove 9, and the baffle 5 is pushed into the first receiving groove 9. The limiting rib 17 presses against the guide surface 54, and the elastic element 52 bends and deforms towards the other elastic element 52. After the clamping head 53 passes the limiting rib 17, the elastic element 52 rebounds, and the side of the clamping head 53 near the baffle body 51 abuts against the limiting rib 17 to prevent the baffle 5 from being pulled out. At this time, the inner side of the baffle body 51 is flush with the support surface.

[0042] As one implementation, a second receiving groove 18 is provided on the outer side of the third profile section 8, which is used to receive the end of another fastener 10.

[0043] The above settings facilitate the use of fasteners 10 to lock the second movable profile 4, improve the stability of the second movable profile 4, and prevent the second movable profile 4 from being pulled out of the second mounting slot 13.

[0044] After one side of the second movable profile 4 is pressed into the second mounting groove 13, another self-tapping screw passes through the third profile part 8 from the second receiving groove 18 and drills into the second movable profile 4 to prevent the second movable profile 4 from being pulled out of the second mounting groove 13.

[0045] As one implementation method, the openings of the first mounting groove 12 and the second mounting groove 13 are provided with protrusions, the height of which is less than or equal to 1mm.

[0046] By setting the above, the friction between the first movable profile 3 and the first mounting groove 12, and the friction between the second movable profile 4 and the second mounting groove 13 are increased, thereby improving the stability of the first movable profile 3 and the second movable profile 4.

[0047] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
