Description

Technical Field

[0001] The invention relates to the technical field of anti-theft doors, and in particular to a convenient replacement device for building anti-theft doors. Background Art

[0002] For existing roughcast and finished houses, developers will reserve doors and windows in advance. Some owners need to replace the matching anti-theft doors. However, the door frame of the anti-theft door is bonded to the wall with cement to ensure its firmness. If you want to remove the anti-theft door, you must smash the wall around the door frame together before you can remove it. After replacing the new door, you need to re-brick and re-paint with cement. The whole replacement process is relatively large and time-consuming.

[0003] When replacing existing anti-theft doors, most of them are carried out manually, which makes the door body prone to tipping over after disassembly. In addition, during the construction process, the construction cement at the door frame needs to be removed, which easily causes the door body to move, making it inconvenient to continue disassembling and easily causing safety accidents. Summary of the invention

[0004] The object of the present invention is to provide a convenient replacement device for building anti-theft doors to solve the problems raised in the above-mentioned background technology.

[0006] Preferably, the front side walls of the two sleeves are respectively provided with sliding grooves, the top walls of the two sleeves are respectively provided with movable grooves, the outer surfaces of the left and right ends of the two double-threaded rods are respectively sleeved with thread rings, the outer surfaces of several of the thread rings are respectively fixedly connected with clamping plates, and several of the clamping plates are respectively slidably arranged inside the sliding grooves and extend to the outside.

[0007] Preferably, a placement plate is provided at the central axis of the support frame, the interior of the placement plate is hollowed out, a transverse groove is opened on the rear outer surface of the placement plate, suction cups are provided on the left and right ends of the placement plate away from the transverse groove, and the two suction cups are connected to the outer surface of the placement plate.

[0008] Preferably, a moving rod is fixedly connected between the outer surfaces of the upper and lower threaded rings, and a connecting piston plate is fixed at the central axis of the two moving rods, and the two piston plates are slidably arranged inside the placement plate, wherein the two piston plates are fixedly connected to the outer surfaces of the central axis of the two moving rods through two connecting rods, and the two connecting rods are slidably arranged inside the transverse groove.

[0009] Preferably, the left and right sides of the support frame are hollowed out, and arc-shaped pull rods are fixedly connected to the side walls of the two moving rods, and the ends of several arc-shaped pull rods away from the moving rods slide through the outer wall of the support frame and extend to the interior, and the extended parts of several arc-shaped pull rods are fixedly connected to extrusion plates, and arc-shaped deformation rods are fixedly connected between the pull rod extrusion plates, and the arc-shaped protruding sides of the two arc-shaped deformation rods face the front of the device.

[0010] Preferably, a plurality of auxiliary grooves are respectively opened on the outer walls on both sides of the support frame, and two auxiliary rods are respectively fixedly connected to the outer surfaces of the two arc-shaped deformation rods, and the two auxiliary rods are respectively slidably arranged inside the two auxiliary grooves, and guide rods are fixedly connected to the central axes of the two auxiliary rods.

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

[0012] (1) The convenient replacement device for building anti-theft doors can make the clamping plates move away from or closer to each other under the action of the threaded rings by rotating the double-threaded rods, thereby achieving the purpose of clamping and fixing the anti-theft door, so that the door body can be fixed during the replacement of the anti-theft door, effectively improving the stability of the door body during disassembly and the stability of the door body during replacement.

[0013] (2) In the convenient replacement device for building anti-theft doors, the double threaded rods approach each other, which causes the moving rod to drive the piston plate to move along the inside of the placement plate, thereby squeezing the gas inside. Under the action of the squeezing force, the gas is discharged through the suction cup, thereby making the inside of the suction cup a vacuum state, achieving the purpose of adsorbing the anti-theft door, and enhancing the clamping effect of the device on the anti-theft door.

[0014] (3) The convenient replacement device for the building anti-theft door, after the anti-theft door is pressed, the double threaded rods move away from each other, which causes the piston plates to move away from each other along the inside of the placement plate under the action of the moving rod, and then in this state, negative pressure is generated inside the placement plate, so that gas can enter the inside of the suction cup, breaking its original vacuum state, so as to facilitate the removal of the anti-theft door from the device.

[0015] (4) The convenient replacement device for building anti-theft doors and the distance between the double threaded rods will cause the arc-shaped pull rod to squeeze the arc-shaped deformation rod, causing it to deform under the action of squeezing. Since the arc-shaped deformation rod faces outward, when the double threaded rods are away from each other, the arc-shaped deformation rod will deform outward. Then, under the action of the auxiliary rod, the guide rod exerts an outward force on the anti-theft door, thereby enhancing the effect of removing the anti-theft door from the device.

[0030] Working principle:

[0031] When the anti-theft door needs to be installed, the staff can start the motor 22. The start of the motor 22 will drive the belt 21 to rotate, and the two double-threaded rods 2 will rotate under the drive of the belt 21. The rotation of the double-threaded rods 2 will cause the clamping plates 33 to move away from each other under the action of the thread ring 32, and move closer to each other to clamp the anti-theft door, so that the door body can be fixed during the replacement of the anti-theft door, effectively improving the stability of the door body during disassembly and the stability of door body replacement. Secondly, the mutual approach of the double-threaded rods 2 will cause the moving rod 5 to drive the piston plate 51 to move along the inside of the placement plate 4, and then squeeze the internal gas. Under the action of the squeezing force, the gas will be discharged through the suction cup 42, so that the inside of the suction cup 42 is in a vacuum state, thereby achieving the purpose of adsorbing the anti-theft door and enhancing the clamping effect of the device on the anti-theft door.

[0032] At the same time, when the anti-theft door is pressed, the double-threaded rods 2 move away from each other, which will cause the piston plate 51 to move away from each other along the inside of the placement plate 4 under the action of the moving rod 5, and then in this state, negative pressure will be generated inside the placement plate 4, so that the gas can enter the inside of the suction cup 42, breaking its original vacuum state, thereby facilitating the removal of the anti-theft door from the device. Secondly, the double-threaded rods 2 move away from each other, which will cause the arc-shaped pull rod 6 to squeeze the arc-shaped deformation rod 62, causing it to deform under the action of squeezing. Since the arc-shaped deformation rod 62 faces outward, therefore, when the double-threaded rods 2 move away from each other, the arc-shaped deformation rod 62 will be deformed outward, and then under the action of the auxiliary rod 71, the guide rod 72 has an outward force on the anti-theft door, thereby enhancing the effect of removing the anti-theft door from the device.
