Description

Technical Field

[0001] This utility model belongs to the field of door frame connection technology, and in particular, a novel integrated door frame. Background Technology

[0002] Stainless steel door frames typically used at the openings of display cases are made by separately foaming the horizontal and vertical sections of the door frame and then assembling them onto the display case using a welding process. However, this construction process requires a high level of skill from the workers, and it is inevitable that the welds will not be perfectly perpendicular during the welding process. Furthermore, long-term welding is time-consuming and laborious, which can easily lead to worker fatigue.

[0003] For example, in the utility model patent with publication number CN212447525U, the upper and lower door frames and the left and right door frames are fixed by welding. This requires high skill from the construction workers and is prone to welding misalignment, which can lead to non-vertical welding and affect the normal use of the door frame. In addition, the construction workers are prone to overwork and damage to their health due to long-term welding work. Summary of the Invention

[0004] In view of this, the present invention provides a novel integrated door frame to solve the above problems.

[0005] A novel integrated door frame includes two sets of opposing door frame side panel assemblies, a door frame bottom plate assembly located at one end of the door frame side panel assemblies, and a door frame top plate assembly located at the other end of the door frame side panel assemblies. Each door frame side panel assembly includes an inner door frame side panel, a door frame side decorative panel corresponding to the inner door frame side panel, and a connecting member located on the side of the inner door frame side panel and the door frame side decorative panel facing the door frame top plate assembly. The inner door frame side panel, the door frame side decorative panel, and the connecting member each include first and second top mounting through holes, a first connecting through hole, and first and second bottom mounting through holes, and a second connecting through hole. The first and second top mounting through holes correspond to the first and second connecting through holes. The door frame bottom plate assembly includes a bottom plate reinforcing plate. The bottom plate reinforcing plate includes multiple pairs of opposing first bottom plate through holes, which correspond to the first and second bottom mounting through holes. The door frame top plate assembly includes a door frame top plate. The top plate of the door frame includes multiple pairs of first top plate through holes corresponding to the second connecting through holes, and multiple pairs of second top plate through holes corresponding to the first connecting through holes.

[0006] Furthermore, the door frame side panel assembly also includes a connecting fastener inserted between the inner door frame side panel and the door frame side decorative panel, and a polystyrene block inserted between the inner door frame side panel and the door frame side decorative panel for heat insulation.

[0007] Furthermore, the connecting fastener includes two insertion slots located on both sides of the connecting fastener, and the two insertion slots are respectively used to insert the inner panel of the door frame side and the decorative panel of the door frame side to connect and fix the inner panel of the door frame side and the decorative panel of the door frame side relative to each other.

[0008] Furthermore, the door frame side inner panel also includes a side inner panel body and a first bent portion located on the side of the side inner panel body facing the door frame top panel assembly, the first bent portion being used to carry the first top mounting through hole.

[0009] Furthermore, the door frame side decorative panel also includes a side decorative panel body and a second bent portion located on the side of the side decorative panel body facing the door frame top panel assembly. The second bent portion is used to carry the second top mounting through hole, and the second bent portion and the first bent portion are disposed opposite to each other.

[0010] Furthermore, the base plate reinforcing plate also includes a base plate body and multiple pairs of second base plate through holes disposed opposite to each other on the base plate body.

[0011] Furthermore, the door frame bottom plate assembly also includes a bottom plate decorative plate sleeved on the bottom plate reinforcing plate. The bottom plate decorative plate includes a bottom plate decorative plate body sleeved on the bottom plate reinforcing plate and multiple pairs of third bottom plate through holes disposed opposite to each other on the bottom plate decorative plate body.

[0012] Furthermore, the door frame top panel assembly also includes a top panel cover plate disposed on the door frame top panel, and a top panel decorative panel sleeved on the outside of the door frame top panel.

[0013] Furthermore, the top plate cover includes a cover body, a plurality of third top plate through holes formed on the cover body and corresponding to the first top plate through holes, and a plurality of fourth top plate through holes formed on the cover body and corresponding to the third top plate through holes.

[0014] Furthermore, the top plate decorative panel is used to decorate the top plate of the door frame, and it includes multiple pairs of fifth top plate through holes corresponding to the third top plate through holes.

[0015] Compared with the prior art, the novel integrated door frame provided by this utility model uses screws passing through the second and third bottom plate through holes to connect and fix the bottom plate reinforcing plate and the bottom plate decorative plate to form the door frame bottom plate assembly. Screws are then passed through the first bottom plate through hole, the first bottom mounting through hole, and the first bottom plate through hole and the second bottom mounting through hole to fix the door frame side inner plate and the door frame side decorative plate to the bottom plate reinforcing plate. Alternatively, screws can be passed through the third top plate through hole, the first top plate through hole, the fifth top plate through hole, the second connecting through hole, and the second top mounting through hole to install and fix the door frame top plate assembly to the door frame side decorative plate. Screws are also passed through the third top plate through hole, the second top plate through hole, the first connecting through hole, and the first top mounting through hole to install and fix the door frame top plate assembly to the door frame side inner plate. Compared with the traditional welding assembly method, this utility model uses mounting holes and screws to fix the new door frame into one piece. This not only reduces the construction requirements for workers, but also allows for direct splicing according to the reserved mounting holes during assembly. This saves time on drilling and measuring, and also avoids the problem of the door frame not being vertical after assembly. Attached Figure Description
