Description

Technical Field

[0001] This utility model belongs to the field of PVC door frame technology, specifically, it relates to a standardized adjustable control PVC door frame. Background Technology

[0002] PVC door frames use rigid polyvinyl chloride (RPVC) as the base material, and coloring materials (such as PMMA or ASA) are usually added through a co-extrusion process to enhance the surface texture. To improve strength, reinforcing steel is embedded inside the profile, and different specifications of steel are selected according to the wind pressure resistance requirements.

[0003] Doors can be classified into hinged doors, sliding doors, and folding doors according to their opening method. Hinged doors offer better sealing, while sliding doors save space.

[0004] Existing PCV door frames may have uneven or tilted tops at the door opening during installation. This can prevent the top frame of the door frame from fitting snugly into the door opening, making it prone to wobbling when installing expansion bolts and causing the installation to tilt. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] To address the problem mentioned in the background art that existing PCV door frames may have tilted or uneven tops at the door opening during installation, making it difficult for the top frame of the door frame to fit snugly against the door opening and causing it to wobble when installing expansion bolts, resulting in installation tilt, this utility model adopts the following technical solution.

[0007] A standardized adjustable control PVC door frame includes a mounting top frame, mounting vertical frames inserted into the bottom of both sides of the mounting top frame, a sliding track provided at the bottom of the mounting top frame, an adjustment component installed inside the sliding track, and a fixing component installed on the adjustment component. The adjustment component causes the fixing component to move upward to contact the top of the door opening.

[0008] Preferably, an adhesive injection assembly is installed on the mounting frame, and the adhesive injection assembly is fitted to the inner walls of both sides of the door opening.

[0009] Preferably, the top frame is provided with first insertion slots at both ends, and the upper end of the vertical frame is fixedly connected with an insertion block that inserts into the first insertion slots.

[0010] Preferably, the fixing component includes a connecting top plate and elastic telescopic columns. A through groove is provided on the top inner side of the sliding track, and sliding grooves are provided on both sides of the inner side of the sliding track. The connecting top plate is slidably connected to the inside of the sliding track. Sliding plates that are slidably connected to the sliding grooves on both sides are fixedly connected to both ends of the connecting top plate. Multiple elastic telescopic columns are provided at the upper end of the connecting top plate. Each elastic telescopic column has an outward stretching elastic force. When the connecting top plate moves upward, the elastic telescopic column adaptively retracts after contacting the top of the door opening.

[0011] Preferably, the adjustment assembly includes a sliding plate, a sliding groove, and a first driving screw. A sliding rod is fixedly connected inside the sliding groove on one side, and the first driving screw is rotatably connected inside the sliding groove on the other side. One sliding plate is slidably connected to the outer wall of the sliding rod, and the other sliding plate is threadedly connected to the outer wall of the first driving screw. Rotating the first driving screw causes the connecting top plate to move upward through the two sliding plates.

[0012] Preferably, the glue injection assembly includes a mounting groove, a positioning pin, a second drive screw, a U-shaped frame, a through groove, and a glue injection port. The two outer walls of the mounting vertical frame are provided with mounting grooves, and the opposite surfaces of the two mounting vertical frames are provided with second insertion grooves. The positioning pin is fixedly connected to one side of the mounting groove, and the second drive screw is rotatably connected to the other side. The U-shaped frame is slidably connected to the mounting groove, and the U-shaped frame is slidably connected to the positioning pin and threadedly connected to the second drive screw. The outer wall of the U-shaped frame is provided with a through groove. A glue injection port is provided near the top of the mounting vertical frame. The upper end of the mounting vertical frame is fixedly connected to an insertion block that inserts into the first insertion groove. Rotating the second drive screw causes the U-shaped frame to move outward and contact the two outer walls of the doorway.

[0013] Preferably, the ends of the first drive screw and the second drive screw are provided with internal hexagonal grooves.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. By moving the connecting top plate in the fixed component upward, the elastic telescopic column retracts adaptively after contacting the top of the door opening, thereby fixing the door frame and preventing it from moving when the expansion bolts are installed. By rotating the first drive screw in the adjustment component, the connecting top plate moves upward through the sliding plates on both sides, thereby adjusting the rising height of the connecting top plate and the contact pressure between the elastic telescopic column and the top of the door opening according to the specific deviation of the top of the door opening.

[0016] 2. By rotating the second drive screw in the glue injection assembly, the U-shaped frame moves outward to contact the outer walls on both sides of the door opening, thereby fixing the door frame and improving the fixing effect. Foam is injected into the interior of the U-shaped frame through the glue injection port and contacts the inner wall of the door opening through the penetration groove, making glue injection more convenient.
