Description

Technical Field

[0001] This utility model belongs to the field of security door technology, and more specifically, it relates to a stainless steel security door with an enhanced impact resistance structure. Background Technology

[0002] Doors and windows are essential components of buildings, and their security has gradually improved with social development. Security doors are a common choice for most buildings. Currently, security improvements in security doors are mainly achieved through the locks. For example, utility model patent CN214006964U discloses a security door that adds an anti-theft sliding lock, giving it a double protection function and increasing the difficulty of unlocking, thereby improving its anti-theft performance. However, besides unlocking, the strength of the door itself is also a factor in its anti-theft performance. When security doors with multiple anti-theft locks are impacted, the impact on the door leaf is easily transmitted to the edge of the door frame, causing deformation and damage to the security door. In such cases, the lock pins can be opened directly without restriction, rendering the security door unusable.

[0003] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a stainless steel security door with enhanced impact resistance, in order to achieve a more practical value. Summary of the Invention

[0004] To solve the above-mentioned technical problems, this utility model provides a stainless steel security door with an enhanced impact-resistant structure. This addresses the issue that when a security door is impacted, the impact on the door leaf is transmitted to the edge of the door frame, causing deformation and damage to the security door. In such cases, the door becomes unusable, except that the lock pin can be opened directly without restriction.

[0005] The purpose and effect of this utility model of a stainless steel security door with enhanced impact resistance structure are achieved by the following specific technical means:

[0006] A stainless steel security door with enhanced impact resistance includes a door frame and a door leaf. The door frame includes a front frame and a rear frame. The door leaf is hinged to the front frame. The front frame and the rear frame are connected by multiple connecting pieces distributed around the perimeter of the door frame. The inner circle of the rear frame is provided with an L-shaped reinforcing liner. The inner wall size of the reinforcing liner is smaller than that of the inner wall size of the front frame. An anti-vibration frame is engaged between the reinforcing liner and the front frame. The anti-vibration frame abuts against the door leaf when closed. The anti-theft lock of the door leaf cooperates with the front frame.

[0007] Furthermore, the anti-vibration frame is a hollow rubber frame, and a serpentine elastic bar is provided inside the hollow cavity.

[0008] Furthermore, two baffles are provided at the four corners of the seismic frame to form installation corner grooves. A fan-shaped connecting tile is inserted in the installation corner groove. The serpentine elastic bar passes through the baffles and connects with the connecting tile. The four connecting tiles and the serpentine elastic bar form a rectangular frame inside the hollow cavity of the seismic frame.

[0009] Furthermore, the shock-absorbing frame is made of rubber, and the serpentine spring bar is made of metal.

[0010] Furthermore, the connecting piece is U-shaped, with the front frame and the rear frame connected to each other on both sides, and a shock-absorbing spring located between the front frame and the rear frame is fitted inside the connecting piece.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] With the layered door frame design, when the door is closed, the inside of the door abuts against the shock-absorbing frame. If the door is impacted, the impact is transmitted to the shock-absorbing frame, which can then absorb the force before it is transmitted to the rear frame. The anti-theft lock on the door forms a lock with the front frame, reducing the force on the front frame when the security door is impacted. If the front frame is not easily deformed, the security door is less likely to be damaged. Attached Figure Description

In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example

[0023] As attached Figure 1 To be continued Figure 5 As shown:

[0024] This utility model provides a stainless steel security door with an enhanced impact-resistant structure, including a door frame 1 and a door leaf 2. The door frame 1 includes a front frame 102 and a rear frame 101. The door leaf 2 is hinged to the front frame 102. The front frame 102 and the rear frame 101 are connected by a plurality of connecting pieces 103 distributed around the periphery of the door frame 1. Figure 5 As shown, the connecting piece 103 is U-shaped. The two sides of the connecting piece 103 are connected to the front frame 102 and the rear frame 101 respectively. The connecting piece 103 is fitted with a shock-absorbing spring 3 located between the front frame 102 and the rear frame 101. When the front frame 102 is impacted, the shock-absorbing spring 3 can buffer and dissipate the force. Even if the force is too great, only the connecting piece 103 will deform, without affecting the door frame 1, thus avoiding damage to the security door caused by the deformation of the door frame 1.

[0025] An L-shaped reinforcing liner 1011 is provided on the inner ring of the rear frame 101. The inner wall dimension of the reinforcing liner 1011 is smaller than that of the inner wall dimension of the front frame 102, so that the door leaf 2 corresponds to the reinforcing liner 1011 when closed. An anti-vibration frame 104 is engaged between the reinforcing liner 1011 and the front frame 102, and the anti-vibration frame 104 abuts against the closed door leaf 2. Figure 3 and Figure 4 As shown, the seismic frame 104 is a hollow rubber frame, and a serpentine elastic bar 1041 is provided inside the hollow cavity. The serpentine elastic bar 1041 can absorb the impact received by the seismic frame 104.

[0026] Two baffles 1042 are provided at the four corners of the seismic frame 104 to form installation corner grooves. Fan-shaped connecting tiles 1043 are installed in the installation corner grooves. Since the connecting tiles 1043 are convex fan-shaped hollow bodies, the serpentine elastic strips 1041 pass through the baffles 1042 and connect with the connecting tiles 1043. The end of the serpentine elastic strips 1041 is inserted into one side of the connecting tiles 1043. The four connecting tiles 1043 and the serpentine elastic strips 1041 form a rectangular frame in the hollow cavity of the seismic frame 104. The connecting tiles 1043 connect the four sides of the serpentine elastic strips 1041 into a whole, increasing the overall stability and structural strength. At the same time, it is convenient to disassemble and assemble the serpentine elastic strips 1041. Since the seismic frame 104 is made of rubber and the serpentine elastic strips 1041 are made of metal, the serpentine elastic strips 1041 will corrode after long-term use and lose their elasticity. The seismic frame 104 can be cut open to replace the serpentine elastic strips 1041.

[0027] In addition, mounting cylinders 1041 are provided at the four corners of the seismic frame 104, and bolts can pass through the mounting cylinders 1041 to connect the front frame 102 and the rear frame 101, further strengthening the connection between the front frame 102 and the rear frame 101.

[0028] The door frame 1 is formed by the front frame 102 and the rear frame 101. The anti-theft lock of the door leaf 2 cooperates with the front frame 102. If the door leaf 2 is impacted, the impact is transmitted to the shock-absorbing frame 104. The impact is then dissipated by the shock-absorbing frame 104 before being transmitted to the rear frame 101. The anti-theft lock on the door leaf 2 is locked to the front frame 102. The anti-theft door can be used normally as long as the front frame 102 is not deformed or damaged. This reduces the force on the front frame 102 when the anti-theft door is impacted, thereby improving the impact resistance of the anti-theft door and making it less prone to damage.

[0029] Among them, multiple notches 105 are opened on one side of the front frame 102, and hinges 201 are rotatably installed in the notches 105, and the hinges 201 are connected to the door leaf 2.

[0030] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
