Description

Technical Field

[0001] The utility model relates to the field of anti-theft doors, in particular to a push-pull anti-theft door. Background Art

[0002] The full name of the anti-theft door is anti-theft security door. It has both anti-theft and safety properties. It is equipped with an anti-theft lock. It can resist abnormal opening under certain conditions within a certain period of time. It has certain safety protection performance and meets the corresponding anti-theft security level.

[0003] Sliding security doors can save space, do not take up extra space when opened, keep the passage unobstructed, and the movement of sliding doors is simpler and more natural than turning movements.

[0004] The existing push-pull security door has lower pulleys at intervals on the lower edge, which slide in conjunction with the translation guide rail and are fixed by an anti-theft chain. However, this method makes it easy for bad guys to break into or control the security door, thereby reducing the security of the security door. In addition, there is a problem of poor ventilation, which easily causes users to feel uncomfortable, thereby reducing the practicality of the security door. Utility Model Content

[0005] Based on this, the purpose of the present invention is to provide a sliding anti-theft door to solve the technical problems mentioned in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a sliding anti-theft door, comprising an installation frame, wherein the upper and lower ends of the inner wall of the installation frame are provided with a first slot, a second slot connected to the outside is provided on one side of the inner wall of the installation frame, and the second slot is connected to the first slot, a door panel is slidably arranged in the first slot, a first docking block is installed on the installation frame, a second docking block matching the first docking block is installed on the door panel, and the first docking block and the second docking block are both installed by fixing parts, and a locking component matching the second docking block is provided in the first docking block.

[0007] By adopting the above technical solution, the door panel can be easily installed by sliding. When the door panel is slid closed, the first docking block and the second docking block are docked to complete the locking, which facilitates enhancing safety.

[0008] The utility model is further configured as follows: the locking assembly includes a first mounting groove provided on one side of the first docking block, a second mounting groove provided on one side of the second docking block, a movable block is installed in the first mounting groove, and the movable block extends from one end of the first docking block, a hook matching the movable block is installed in the second mounting groove, a sliding block is provided at the end of the hook, a sliding groove matching the sliding block is provided on the inner wall of one side of the second mounting groove, a limiting block is installed in the first mounting groove, and the limiting block is located on one side of the movable block, a protrusion matching the hook is provided on the limiting block, a second return spring is fixed between the inner wall of the second mounting groove and the outer surface of one side of the hook, and a matching unlocking mechanism is provided in the first docking block and the second docking block.

[0009] By adopting the above technical solution, it is convenient to lock the door panel when closing it. By pushing the door panel, the second docking block installed on the door panel is driven to move forward until the hook enters. When the front end of the hook touches a small protrusion on the limit block, the hook will move backward. The hook moves in the sliding groove under the action of the bottom sliding block. When the hook part at the front end of the hook passes over the protrusion part where the limit block is located, the hook is driven to reset under the action of the second reset spring, and the notch part at the front end of the hook engages with the protrusion part of the limit block to complete the fixation.
