Description

Technical Field

[0001] This utility model relates to the field of medical door technology, and in particular to an adaptive plug-in double-door frame. Background Technology

[0002] Currently, the most prominent problem with steel medical doors is the door frame. Most steel door frames are double-framed structures, typically installed using expansion bolts. This requires drilling bolt holes at the installation location, affecting aesthetics and resulting in large, unsightly gaps between the main and secondary frames. Furthermore, uneven wall thickness on-site necessitates custom-fabricating double-frames based on the actual opening thickness, leading to inefficiency and increased processing and installation difficulty. Therefore, there is an urgent need to design an adjustable, seamless, plug-in double-frame design without expansion bolt holes to solve these problems. Utility Model Content

[0003] The purpose of this utility model is to provide an adaptive plug-in double-sided door frame to solve the problems in the above-mentioned background technology, such as the non-adjustable width of the double-sided door frame, the inability of the door frame side wall width to be adjusted according to the actual thickness of the wall, and the large and unsightly gaps at the joint surfaces of the main and secondary frames.

[0004] To achieve the above objectives, this utility model provides an adaptive plug-in double-door frame, including a main frame, a sub-frame, a tie rod, and an embedded elastic seal. The sub-frame is L-shaped, and both the main frame and the sub-frame have hook edges at one end. The other end of the main frame has a side hook edge. The main frame has a U-shaped rubber strip groove, and the embedded elastic seal is disposed in the U-shaped rubber strip groove. The tie rod is fixedly connected to the main frame, and the sub-frame is plugged between the side hook edge and the tie rod.

[0005] Preferably, the tie rod is fixed by welding it to the pre-embedded expansion bolt or by using polyurethane foam. The tie rod includes a tie rod body and a support plate. One end of the tie rod body is fixedly connected to one side of the U-shaped adhesive strip groove. One end of the support plate is fixedly connected to the tie rod body, and the other end of the support plate is fixedly connected to the side hook edge.

[0006] Preferably, the end of the tie rod body away from the Z-shaped adhesive strip groove is attached to the side hook edge, and the tie rod body is higher than the main frame surface.

[0007] Preferably, the main body of the tie rod is configured as a U-shaped structure, and the support plate is configured as an arc-shaped structure.

[0008] Preferably, the main frame and the sub-frame are combined using a flat insertion method, and the insertion depth is adjusted within a range of 10-30mm.

[0009] Preferably, both the main frame and the sub-frame include a horizontal frame and a vertical frame, and the horizontal frame and the vertical frame are connected by an overlay-type plug-in method.

[0010] Therefore, the adaptive plug-in double-opening door frame of this utility model with the above-described structure has the following beneficial effects:

[0011] (1) By setting the main frame and the sub-frame as horizontal and vertical frames respectively, and using the wrapping plug-in fixed connection for the horizontal and vertical frames, seamless plug-in connection and beautiful appearance are achieved. The horizontal and vertical frames of the main frame and the sub-frame can be shipped separately, which is convenient for transportation and on-site assembly, reducing the difficulty of processing and installation.

[0012] (2) The tie rods are fixed by pre-embedded expansion bolt welding or polyurethane foam, which eliminates the need to drill expansion bolt holes on the door frame and improves the overall aesthetics of the door frame.

[0013] (3) The main frame and the sub-frame are combined by flat insertion. The insertion depth can be adjusted to accommodate the error caused by non-standard thickness of the opening. It is highly adaptable. After insertion, the exposed side of the sub-frame is about 25mm, which ensures that the gap between the two joint surfaces is small after the sub-frame is inserted into the main frame, thus improving the overall aesthetics.

[0025] Example

[0026] The technical solutions in the embodiments of this utility model will now be clearly and completely described with reference to the accompanying drawings.

[0027] like Figure 1-2 As shown, an adaptive plug-in double-opening door frame includes a main frame 1, a sub-frame 3, a tie rod 2, and an embedded elastic seal 4. The main frame 1 is an external frame structure with a flat snap-fit ​​edge on the front. The sub-frame 3 is L-shaped, with its front structure identical to that of the main frame 1. The side with the flat plate is the insertion side. Both the main frame 1 and the sub-frame 3 have a hook edge 5 at one end, which is flush with the wall to ensure the perpendicularity of the door frame to the opening and maintain the aesthetics of the door frame. The other end of the main frame 1 has... The side hook edge 6 and the main frame 1 are provided with a Z-shaped rubber strip groove. The embedded elastic seal 4 is set in the Z-shaped rubber strip groove, which can increase the sealing and sound insulation performance of the door. The tie rod 2 is fixedly connected to the main frame 1. The tie rod 2 is fixed by welding with the pre-embedded expansion bolt or by polyurethane foam. The expansion bolt is first pre-embedded in the wall and then the tie rod is welded to the pre-embedded expansion bolt. This can save the need to open expansion bolt holes in the door frame and improve the overall aesthetics of the door frame. The sub-frame 3 is inserted between the side hook edge 6 and the tie rod 2.

[0028] The main frame 1 and the sub-frame 3 are assembled using a flat plug-in method. The plug-in depth is adjustable from 10-30mm, which can accommodate errors caused by non-standard thickness of the opening, making it highly adaptable. After plugging, the exposed side of the sub-frame 3 is about 25mm, ensuring a small gap at the joint surface of the sub-frame 3 and the main frame 1, thus ensuring an overall aesthetically pleasing appearance. Both the main frame 1 and the sub-frame 3 include horizontal and vertical frames, which are connected by an overlay plug-in method to achieve a seamless and aesthetically pleasing appearance. They can also be shipped separately for convenient transportation and on-site assembly to improve efficiency.

[0029] like Figure 3-7 As shown, the tie rod 2 includes a tie rod body 21 and a support piece 22. One end of the tie rod body 21 is welded to the upper side of the Z-shaped rubber strip groove at welding point 3 9. After inserting the rubber strip, the welding point can be hidden. One end of the support piece 22 is welded to the tie rod body 21 at welding point 2 8. The other end of the support piece 22 is welded to the side hook edge 6 at welding point 1 7. The main frame 1 covers welding point 1 7, achieving overall welding point concealment and aesthetic appearance. The end of the tie rod body 21 away from the Z-shaped rubber strip groove is attached to the side hook edge 6. After being attached tightly, welding points 2 8 and 3 9 are positioned for easy welding. Moreover, tight welding can improve clamping force and ensure the gap of the contact surface. In addition, the tie rod body 21 is higher than the frame surface of the main frame 1, which facilitates the insertion of the sub-frame 3. The end of the tie rod body 21 that extends beyond the main frame 1 serves as a guide when inserting the sub-frame 3. At the same time, the rounded corners of the side hook edge 6 facilitate the insertion of the sub-frame 3.

[0030] The main body 21 of the tie rod is set as a U-shaped structure, and the support plate 22 is set as an arc-shaped structure. The arc-shaped structure has a certain bending strength, and the hollow part of the arc ensures the amount of gap when inserting the sub-frame 3. The only obstacle when inserting is the friction between the initial tie rod main body 21 and the side hook edge 6.

[0031] Therefore, the adaptive plug-in double-opening door frame of this utility model, which adopts the above-mentioned structure, can adjust the insertion depth of the sub-frame into the main frame according to the actual thickness of the opening on site, reducing the processing and installation difficulty, improving construction efficiency, and the tie rod is welded to the main frame, realizing the concealment of the overall welding points and the appearance is beautiful.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solution of this utility model, and these modifications or equivalent substitutions cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of this utility model.
