Description

Technical Field

[0001] The invention relates to the technical field of fixing components on door leaves, and in particular to an installation structure of a safety door installation component. Background Art

[0002] With the development of door lock technology and the improvement of people's living standards, door locks must not only meet people's safety needs, but the appearance of door locks has gradually become an important factor in people's choice of door locks. For anti-theft doors and security doors, the common fixed devices in the past are mostly door handles, or cat's eyes, etc. In this type of device, the door handle is usually fixed by screws on the front and rear panels. For example, Chinese patent document CN203008536U discloses an anti-disassembly door lock panel, which specifically includes inner and outer panels, the back of the outer panel is fixed with screws, the inner panel is provided with screw holes corresponding to the screws on the outer panel, and also includes a screw connected to the screw of the outer panel, and the screw passes through the screw hole of the inner panel and connects with the screw on the outer panel to pull the inner and outer panels together and fix them on the door. It can be seen that in the prior art, the design idea is to avoid exposing the fixings on the outside of the door leaf, so as to prevent illegal actors from disassembling the fixings to achieve the purpose of opening the door and entering the house. In this way, the prior art uses a fixing that passes through the door leaf to fix the installation parts set on the outside of the door leaf, and sets the operable fixings on the inside of the door leaf, such as the above prior art is set on the door panel.

[0026] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0027] like Figures 1 to 3 The figure shows a specific embodiment of the installation structure of the safety door installation part, which includes: a door panel 1 with an installation opening, a fixing frame 2 arranged on one side of the installation opening of the door panel 1 and recessed into the door leaf to form an installation cavity, a first fixing member 3 fixedly connected to the installation member 18, and a locking member 4 arranged on the fixing frame 2 to be movable parallel to the door panel 1.

[0028] In this embodiment, the fixing frame 2 is composed of a frame body 5 and a second fixing member 6. The frame body 5 is a box-shaped structure surrounded by four sides and a bottom plate fixed on the door panel 1. The edges of the open sides of the box-shaped structure are fixedly connected to the edges of the installation opening of the door panel 1 by welding, and the concave cavity of the box-shaped structure concave inwardly toward the door leaf constitutes the installation cavity. The second fixing member 6 is fixed to the inner wall of the bottom plate of the installation cavity of the frame body 5 by screws. The first fixing member 3 is fixed to the side of the bottom plate of the mounting member 18 facing the frame body 5 by screws. Mutually matching convex and concave plug-in structures are provided on the opposite surfaces of the first fixing member 3 and the second fixing member 6 in the assembled state. In this embodiment, a protrusion 20 is provided on the first fixing member 3, and a corresponding snap-in groove 19 is provided on the second fixing member 6.

[0029] The second hole 7 of the through hole is formed on the groove wall of the clamping groove 19 on the second fixing member 6. In this embodiment, the axial direction of the second hole 7 is vertically arranged; the locking member 4 is a locking pin 8 slidably arranged in the second hole 7; the protrusion 20 on the first fixing member 3 is formed with a first hole 9 suitable for the locking pin 8 to extend into at a position corresponding to the second hole 7 after assembly. In this embodiment, the first hole 9 is a screw hole with an internal thread 16, and correspondingly, the corresponding end of the locking pin 8 is provided with an external thread 15 that matches the screw hole. The locking pin 8 is locked and released by rotating in and out of the first hole 9 through the thread. The second fixing member 6 is provided with a mounting portion 10, and a reset member mounting groove 11 is formed between the mounting portion 10 and the groove wall of the clamping groove 19 on the second fixing member 6. The mounting portion 10 is formed with a mounting hole 21 for the locking pin 8 to pass through at a position corresponding to the second hole 7. A clamping groove 13 is provided on the locking pin 8 at a position corresponding to the reset member installation groove 11, and a clamping spring as a first clamping member 14 is clamped on the clamping groove 13. The clamping spring cooperates with the installation portion 10 and the groove wall of the clamping groove 19 to movably clamp the locking pin 8 on the second fixing member 6. A coil spring as a reset member 12 is provided in the reset member installation groove 11 to provide a reset biasing force between the groove wall of the clamping groove 19 and the clamping spring on the locking pin 8.

[0030] In this embodiment, the frame 5 of the fixing frame 2 has been welded to the door panel 1 when the door leaf is formed, so it has been installed on the door when it is shipped as a finished door. In this way, when installing the mounting member 18, first, the first fixing member 3 is fixed to the mounting member 18 by screws, and the second fixing member 6 is fixed to the frame 5 by screws. Then, the first fixing member 3 with the mounting member 18 is dragged through the installation opening in a direction perpendicular to the door panel 1 of the door leaf, enters the installation cavity, and the protrusion 20 provided on the first fixing member 3 and the clamping groove 19 provided on the second fixing member 6 are engaged with each other. At this time, the first hole 9 on the protrusion 20 and the second hole 7 on the clamping groove 19 are aligned with each other. At this time, a tool is inserted from a working hole 17 on the corresponding side of the top of the door leaf, through a hole on the top of the frame body 5 and into the installation cavity, and the tool operates the locking pin 8 installed on the second hole 7 of the clamping groove 19, first pushing the locking pin 8 to overcome the reset bias force applied by the coil spring and move to a position in contact with the first hole 9, and then rotating the locking pin 8 so that the external thread 15 on the locking pin 8 is screwed with the internal thread 16 in the screw hole of the first hole 9. In this way, the installation of the mounting member 18 on the door panel 1 is completed.

[0031] When disassembly is required, the tool is inserted from the working hole 17 on the corresponding side of the top of the door leaf, and extends into the installation cavity through a hole on the top of the frame 5. The tool operates the locking pin 8 installed on the second hole 7 of the clamping groove 19, and rotates the locking pin 8 in the opposite direction to that during installation, so that the external thread 15 on the locking pin 8 is disengaged from the internal thread 16 in the screw hole of the first hole 9. At this time, the return bias force applied by the coil spring to the locking pin 8 through the clamping spring arranged in the clamping groove 13 drives the locking pin 8 to disengage from the protrusion 20 on the first fixing member 3. At this time, the first fixing member 3 is moved in a direction perpendicular to the door panel 1 of the door leaf, so that the protrusion 20 and the clamping groove 19 on the second fixing member 6 are disengaged from each other, thereby completing the disassembly of the installation member 18 on the door panel 1.

[0032] In the above embodiment, a fastening tool connection structure is formed on one end of the locking pin 8 away from the second fixing member 6, and the connection structure is specifically a slot, a cross slot, a hexagonal nut, etc.

[0033] As an alternative implementation in the above embodiment, the reset member 12 provided in the reset member installation groove 11 and providing the reset biasing force between the groove wall of the clamping groove 19 and the clamping spring on the locking pin 8 is removed. The locking pin 8 is a bare rod, and the first hole 9 is a bare hole correspondingly. The locking pin 8 and the corresponding holes are arranged horizontally and slide in the horizontal direction, so that the locking pin 8 can be locked and released by sliding in and out of the first hole 9.

[0034] As an alternative implementation in the above embodiment, the locking member 4 may also be replaced by a rotating arm mounted on the second fixing member 6 with a rotating axis perpendicular to the door panel 1 of the door leaf, and the rotating plane of the rotating arm is parallel to the door panel 1. Correspondingly, a locking groove suitable for the rotating arm to be inserted through rotation is formed on the first fixing member 3, and the movement of the mounting member 18 in the direction perpendicular to the door panel 1 of the door leaf is restricted by the rotating arm and the locking groove.

[0035] As an alternative implementation in the above embodiment, the second fixing member 6 may also be formed directly on the frame 5 by stamping, without having to be installed separately.

[0036] As an alternative implementation in the above embodiment, a clamping groove 19 is provided on the first fixing member 3 , and a protrusion 20 is correspondingly provided on the second fixing member 6 .

[0037] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
