Installation structure of safety door installation

technical field

The invention relates to the technical field of device fixing on a door leaf, in particular to an installation structure of a safety door installation part.

Background technique

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 for people to choose door locks. For anti-theft doors and security doors, most of the common fixing devices in the past are door handles, or cat's eyes and so on. In this type of device, the door handle is usually fixed by pulling the front and back panels with screws. For example, Chinese patent document CN203008536U discloses an anti-removal door lock panel, which specifically includes an inner panel and an outer panel. The back of the outer panel is fixed with screws. There are screw holes corresponding to the screws on the outer panel, and also includes a screw connected with the screws on the outer panel. The screws pass through the screw holes on the inner panel and connect with the screws on the outer panel to fix the inner and outer panels on the door. . It can be seen that in the prior art, the design idea is to avoid exposing the fixing member on the outside of the door leaf, so as to prevent illegal actors from disassembling the fixing member to achieve the purpose of opening the door and entering the house. In this way, in the prior art, a fixing piece passing through the door leaf is used to fix the installation piece provided on the outside of the door leaf, and the operable fixing piece is arranged on the inner side of the door leaf, for example, the above-mentioned prior art is set on the door panel. For this reason, in the prior art, in order to keep the inner and outer surfaces of the door leaf clean, the inner and outer panels provided with the handle are arranged in a set at the same time. However, with the development of technology, installation parts such as cameras and hand touch screens that need to be arranged outside the door leaf do not need to be arranged inside the door leaf with corresponding inner parts, which will make the inside of the door leaf look messy. In order to avoid such clutter in some prior art, the camera and the key board are arranged on the outer handle panel. However, the outer handle panel is not an ideal setting position. Because the setting position is too low, the portrait obtained by the camera is not easy to identify, and the buttons need to be bent over to view, etc., which limits the fixed use of the installation parts outside the door leaf.

Then, drag the first fixing member 3 with the installation member 18 through the installation opening in the direction perpendicular to the door panel 1 of the door leaf, into the installation cavity, and make the first The protrusion 20 provided on a fixing member 3 is fitted with the engaging groove 19 provided on the second fixing member 6 . At this time, the first hole 9 on the protrusion 20 is aligned with the second hole 7 on the snap groove 19 . At this time, a tool inserted from the working hole 17 on the corresponding side of the top of the door leaf is inserted into the installation cavity through a hole at the top of the frame body 5, and the tool is operated and installed in the snap groove The locking pin 8 on the second hole 7 of The locking pin 8 enables the external thread 15 on the locking pin 8 to be screwed together with the internal thread 16 in the screw hole of the first hole 9 . In this way, the installation of the installation member 18 on the door panel 1 is completed.

When it needs to be disassembled, it is still a tool that extends from the working hole 17 on the corresponding side of the door leaf, and extends through a hole on the top of the frame body 5 into the installation cavity, and is operated by the tool to install on the The locking pin 8 on the second hole 7 of the snap groove 19 is rotated in the opposite direction to that during installation, so that the external thread 15 on the locking pin 8 and the first The internal thread 16 in the screw hole of a hole 9 is disengaged, and at this time, the helical spring drives the locking pin 8 through the reset biasing force exerted by the retaining spring provided in the retaining groove 13 on the locking pin 8 . Disengage the protrusion 20 on the first fixing member 3 . At this time, the first fixing member 3 is moved in the direction perpendicular to the door panel 1 of the door leaf, so that the protrusion 20 and the engaging groove 19 on the second fixing member 6 are disengaged from each other, Thus, the disassembly of the installation part 18 on the door panel 1 is completed.

In the above embodiment, the end of the locking pin 8 away from the second fixing member 6 is formed with a fastening tool connection structure, and the connection structure is specifically a slot, a cross groove, a hexagonal nut, and the like.

In the above embodiment, as an alternative implementation, at this time, the reset bias provided between the groove wall of the snap groove 19 and the snap spring on the locking pin 8 in the reset element installation groove 11 is removed. Pressure reset element 12 . The locking pin 8 is a polished rod, and the first hole 9 corresponds to a polished hole. The locking pin 8 and the corresponding holes are arranged horizontally and slide in the horizontal direction, so that the locking pin 8 slides in and out of the first hole. 9 to achieve lock and release.

In the above embodiment, as an alternative implementation, the locking member 4 can also be replaced by a rotating arm that is installed on the second fixing member 6 on the door panel 1 with its rotating axis perpendicular to the door leaf, and the rotating The plane of rotation of the arm is parallel to the door panel 1 . Correspondingly, the first fixing member 3 is formed with a locking groove which is suitable for the rotating arm to be inserted through rotation. The movement of the door panel 1 direction.

In the above-mentioned embodiment, as an alternative implementation, the second fixing member 6 can also be directly formed on the frame body 5 by stamping, and does not need to be installed separately.

In the above-mentioned embodiment, as an alternative implementation, the first fixing member 3 is provided with a snap groove 19 , and the second fixing member 6 is correspondingly provided with a protrusion 20 .
