Description

Technical Field

[0001] This utility model relates to the field of security door technology, specifically a four-dimensional inlaid welded security door. Background Technology

[0002] With increasing demands for building security, security doors, as crucial protective facilities in homes and public places, are receiving growing attention for their structural strength and aesthetic design. Traditional security doors often employ welding to assemble the door leaf and frame, leaving the weld points exposed. This not only affects appearance but also makes the welds susceptible to corrosion over time, leading to a decrease in structural strength. Furthermore, traditional welding processes are prone to door leaf deformation, and exposed weld points are vulnerable to malicious damage, reducing security performance. While some designs attempt to conceal weld points with covers, these methods suffer from installation complexity, high costs, and ineffective concealment.

[0003] Therefore, we propose a four-dimensional inlaid welded security door to solve the problems mentioned above. Utility Model Content

[0004] The purpose of this invention is to provide a four-dimensional inlaid welded security door to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a four-dimensional inlaid welded security door, comprising: a door frame, a door leaf, a door lock, and hinges, wherein the door leaf is installed inside the door frame via hinges, and the door lock is installed on the door leaf.

[0006] The door leaf is composed of an inner welded side panel between two door panels, with the side panel located at the edge of the door panel.

[0007] Preferably, the connection between the door panel and the side guard is bent at 90° to cover the weld point.

[0008] Preferably, the side guard is divided into two parts, which are welded to the two door panels respectively, and the two side guards are welded together.

[0009] Preferably, a stainless steel baffle is fixedly installed on the side guard, and the stainless steel baffle covers the welding points on the side guard.

[0010] Preferably, the stainless steel baffles are distributed on the four sides of the door panel.

[0011] Preferably, the hinge includes hinge plate one and hinge plate two, which are fixedly installed to the door frame and the door leaf, respectively.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By bending the door panel 90° inward to connect the side guard, and by using stainless steel strips to double-cover the weld points, the weld points are completely hidden, avoiding exposure and corrosion, extending service life, and making the door surface more concise and beautiful.

[0014] 2. The internal welding of the side guards and the door panel, combined with the frame distribution of stainless steel retaining strips, forms a four-dimensional support structure, which significantly improves the door leaf's impact resistance and deformation resistance, and enhances its anti-theft performance.

[0015] 3. The split design of the side guards and the pre-welding process of the stainless steel guard strips simplify the production process, reduce the thermal deformation problems caused by traditional welding, and improve production efficiency and product consistency.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-6 This utility model provides a technical solution: a four-dimensional inlaid welded security door, including: a door frame 1, a door leaf 2, a door lock 3 and a hinge 4. The door leaf 2 is installed in the door frame 1 through the hinge 4, and the door lock 3 is installed on the door leaf 2.

[0025] The door leaf 2 is composed of two door panels 21 connected by an internally welded side rail 24. The side rail 24 is located at the edge of the door panel 21. The connection between the door panel 21 and the side rail 24 is bent at 90° to hide the weld point and make it more aesthetically pleasing.

[0026] The side guard 24 is divided into two parts, which are welded to the two door panels 21 respectively, and the two side guards 24 are welded together.

[0027] A stainless steel baffle 22 is fixedly installed on the side panel 24. The stainless steel baffle 22 covers the welding points on the side panel 24, strengthens the overall strength of the door leaf 2, and further hides the welding points, improving the aesthetics.

[0028] Stainless steel baffles 22 are distributed on the four sides of the door leaf 2. The stainless steel baffles 22 are bent into a square shape and fixed to the side baffles 24 by screws.

[0029] Hing 4 includes hinge plate 1 41 and hinge plate 2 42. Hing plate 1 41 and hinge plate 2 42 are fixedly installed to the door frame 1 and the door leaf 2 respectively, so as to realize the rotation and opening of the door leaf 2 and the door frame 1.

[0030] Working principle: The side guards 24 are welded to the door panel 21, and the door panel 21 at the weld point is bent at 90° to cover the weld point, thus hiding the weld point. The weld points between the side guards 24 are covered and hidden by the stainless steel retaining strip 22, so that the weld points of the entire door leaf 2 are hidden, realizing the weld point-free design of the door leaf 2, improving the aesthetics. The stainless steel retaining strip 22 can also improve the overall strength of the door leaf.
