Description

Technical Field

[0001] The utility model relates to the technical field of door edge fastening equipment, in particular to a door edge double-sided fastening device. Background Art

[0002] When installing the door edge, it is often necessary to use a door edge fastening device. The utility model patent with patent application number CN201921120218.5 discloses a bamboo door edge strip installation structure. By changing the connection method between the door edge strip and the wall from gluing to clamping, and at the same time using anti-slip teeth and pins, the door edge strip is subjected to a force applied to the wall, thereby ensuring that the door edge strip and the wall are firmly clamped together, avoiding the door edge strip from falling off due to the decrease in adhesion after using glue, ensuring the bonding strength between the door edge strip and the wall, and improving the service life of the door edge strip, thereby improving the stability and durability of the structure. On the one hand, the bamboo boards and connecting rods are bent so that the door edge strips are subjected to force toward the door frame, thereby avoiding the shaking of the door frame and the door edge strips, ensuring the stability of the door and the fit between the door and the wall, thereby improving the stability of the structure. According to the technical scheme disclosed therein, when the existing door edge fastening equipment is in use, on the one hand, it cannot improve the installation efficiency during installation and fixing, and at the same time, the fixing mechanism is exposed on the outside of the door edge, which is not conducive to ensuring the cleanliness and aesthetics of the surface. On the other hand, after long-term use, it is easy to cause degumming or loose bolts, which is not conducive to ensuring the installation firmness of the door edge.

[0003] Therefore, how to design a double-sided fastening device for the door edge has become the problem we need to solve at present. Utility Model Content

When installing and fixing, the plug block 3 connected and fixed on the support sleeve 2 around the door edge body 1 is inserted into the inner side of the socket in the doorway or door frame, and the bayonet 5 is first squeezed to the inner side of the slot 4 under the push of the inner wall of the socket, and then when the plug block 3 is completely inserted into the inner side of the socket, the bayonet 5 is pushed outward by the spring 6, and the bayonet 5 is locked with the socket, thereby fixing the plug block 3 to the socket, which can quickly complete the installation and fixing of the door edge body 1 and improve work efficiency. At the same time, the support sleeve 2 and the plug block 3 are hidden on the outside of the door edge body 1, thereby improving the aesthetics and neatness of the door edge body 1.

[0023] In this embodiment, one end of the support sleeve 2 is installed on the outer side of the door edge body 1, and the support sleeve 2 is evenly distributed on the outer side of the door edge body 1. One end of the guide rod 7 is integrally formed on one side of the plug block 3. A guide groove 9 is provided on the inner side of the support sleeve 2. The other end of the guide rod 7 passes through the other end of the support sleeve 2 and extends to the inner side of the guide groove 9. A through opening 10 is provided at one end of the support sleeve 2. The block 11 is clamped on the inner side of the through opening 10. One end of the block 11 extends to the outer side of the support sleeve 2. The inclined surface 12 is provided at one end of the block 11. One end of the gear rod 13 is welded to the other end of the block 11. The other end of the gear rod 13 is clamped on the outer side of the other end of the guide rod 7.

When in use, after the support sleeve 2 and the plug block 3 are inserted into the inner side of the socket, the inner wall of the socket pushes the stopper block 11 toward the inner side of the through opening 10 through the inclined surface 12, so that the stopper rod 13 in the support sleeve 2 moves downward on the inner side of the guide groove 9 until the stopper rod 13 moves downward to the inner side of the inner groove 14, and the spring 28 pulls the guide rod 7, and then uses the tension of the spring 28 to clamp the door side body 1 to the inner wall of the door door or door frame. Even when the latch 5 is loose, the contraction of the spring 28 can be used to make the guide rod 7 drive the plug block 3 to move toward the outer side of the door side body 1, thereby effectively keeping the door side body 1 in close contact with the inner wall of the door door or door frame to prevent loosening and ensure the installation firmness of the door side body 1.

[0024] When installing and fixing the double-sided fastening device for the door edge, the plug block 3 connected and fixed on the support sleeve 2 around the door edge main body 1 is inserted into the inner side of the socket in the doorway or door frame. The bayonet 5 is pushed to the inner side of the slot 4 by the inner wall of the socket. Then, when the plug block 3 is fully inserted into the inner side of the socket, the bayonet 5 is pushed outward by the spring 6, and the bayonet 5 is locked with the socket, thereby fixing the plug block 3 to the socket. The installation and fixing work of the door edge main body 1 can be completed quickly, and the work efficiency is improved. At the same time, the support sleeve 2 and the plug block 3 are hidden on the outside of the door edge main body 1, thereby improving the aesthetics and neatness of the door edge main body 1. When in use, the support sleeve 2 and the plug block 3 are inserted. After entering the inner side of the socket, the inner wall of the socket pushes the stopper 11 to the inner side of the through opening 10 through the inclined surface 12, so that the stopper rod 13 in the support sleeve 2 moves downward on the inner side of the guide groove 9 until the stopper rod 13 moves downward to the inner side of the inner groove 14, and the spring 28 pulls the guide rod 7, and then uses the tension of the spring 28 to clamp the door side body 1 to the inner wall of the door door or door frame. Even if the latch 5 is loose, the contraction of the spring 28 can be used to make the guide rod 7 drive the plug 3 to move to the outer side of the door side body 1, thereby effectively keeping the door side body 1 in close contact with the inner wall of the door door or door frame to prevent loosening and ensure the installation firmness of the door side body 1.
