Description

Technical Field

[0001] The utility model relates to the technical field of metal doors and windows, in particular to a metal door and window convenient for disassembly and assembly. Background Technique

[0002] After retrieval, the application number 202321796204.1 discloses a metal door and window convenient for quick disassembly and assembly, including two door and window horizontal frames. There are two door and window vertical frames between the two door and window horizontal frames. Disassembly and assembly mechanisms are arranged between the two door and window horizontal frames and the two door and window vertical frames; the disassembly and assembly mechanism includes a pull block. One side of the pull block is fixedly connected with a pull rod. The pull rod extends into the interior of the door and window horizontal frame. A spring is sleeved outside the pull rod. A rack is arranged outside the spring. A through hole is opened inside the rack. Side plates are arranged on both sides of the rack. A gear is arranged on one side of the rack.

[0003] During the use of the metal door and window convenient for quick disassembly and assembly in the patent application, by using the rack to drive the gear to rotate under the drive of the spring, the gear drives the swing rod to rotate through the rotating shaft and snap into the interior of the limit seat, so that the lateral movement of the door and window horizontal frame and the door and window vertical frame is restricted. Then, through the cooperation of the limit hole and the limit post, the longitudinal movement and the front-back movement of the door and window horizontal frame and the door and window vertical frame are restricted, realizing the convenient installation of the door and window. However, during such use, due to the lack of self-locking ability between the rack and the gear, the rack only forms a positioning effect by the elastic force of the spring, resulting in poor overall structural stability of the door and window. When the door and window vibrates due to being collided or other situations, it is easy for the rack to compress the spring and move, driving the swing rod on the rotating shaft to rotate and disengage from the limit seat, causing the door and window to fall apart. Moreover, when the door and window is installed and disassembled, the staff needs to keep pulling the two pull blocks on the door and window horizontal frame while performing the installation and disassembly operations between the two door and window horizontal frames and the two door and window vertical frames. The operation is relatively cumbersome and not convenient for the staff to complete alone, affecting the installation and disassembly efficiency of the device. Therefore, we propose a metal door and window convenient for disassembly and assembly. Content of the Utility Model

[0004] The utility model mainly solves the technical problems existing in the above-mentioned prior art, and provides a metal door and window convenient for disassembly and assembly.

[0005] To achieve the above object, the present utility model adopts the following technical solutions. A metal door and window that is convenient for disassembly and assembly includes two horizontal door and window frames and two vertical door and window frames arranged between the two horizontal door and window frames. An installation and disassembly mechanism is arranged between the two horizontal door and window frames and the two vertical door and window frames. The installation and disassembly mechanism includes two connecting rotating rods rotatably connected to the inside of the two horizontal door and window frames and four connecting seats fixedly installed inside the two vertical door and window frames. The four connecting seats are distributed in a matrix state and correspond to the left and right ends of the two connecting rotating rods. On one side of the four connecting seats close to the two connecting rotating rods, four connecting jacks adapted to the outer wall surfaces of the left and right ends of the two connecting rotating rods are opened. At the top of the inner wall surface of the four connecting jacks near one end of the two connecting rotating rods, four guiding chutes are penetrated and opened. On the side part of the inner wall surface of the four connecting jacks, four positioning card slots communicated with the four guiding chutes are penetrated and opened. Four positioning rods fixedly connected to the corresponding positions on the outer wall surfaces of the two connecting rotating rods are clamped inside the four positioning card slots. In the middle of the inner cavities of the two horizontal door and window frames, an adjusting mechanism for driving the two connecting rotating rods to rotate is arranged. The adjusting mechanism includes two adjusting worm gears rotatably connected to the top of the middle part of the inner cavities of the two horizontal door and window frames.

[0006] Further, on both the left and right sides of the outer wall surfaces of the two connecting rotating rods, mounting brackets fixedly installed at the corresponding positions on the inner cavity walls of the two horizontal door and window frames are symmetrically rotatably connected.

[0007] Further, the left and right ends of the two connecting rotating rods are respectively inserted into the four connecting jacks.

[0008] Further, the four guiding chutes and the four positioning card slots are arranged perpendicular to each other.

[0009] Further, the four guiding chutes and the four positioning card slots are all adapted to the four positioning rods.

[0010] Further, two adjusting worm wheels meshing with the two adjusting worm gears are fixedly installed in the middle of the outer wall surfaces of the two connecting rotating rods.

[0011] Further, on the sides of the two horizontal door and window frames away from each other, two receiving grooves corresponding to the positions of the two adjusting worm gears are opened.

[0012] Further, the mutually remote ends of the two adjusting worm gears respectively penetrate the inner cavity walls of the two horizontal door and window frames and extend into the two receiving grooves.

[0013] Further, hexagonal grooves are opened on the sides of the two adjusting worm gears located inside the two receiving grooves.

[0014] The present utility model provides a metal door and window that is convenient for disassembly and assembly. It has the following beneficial effects:

[0015] 1. The metal doors and windows that are convenient for disassembly and assembly are provided with a loading and unloading mechanism and an adjusting mechanism. In the initial state, both ends of the two connecting rotating rods are inserted into the four connecting jacks on the four connecting seats, so that the two door and window horizontal frames and the two door and window vertical frames are limited in the front-back direction and the up-down direction. Then, the four positioning rods on the two connecting rotating rods are clamped into the four positioning grooves on the two connecting seats, so that the two door and window horizontal frames and the two door and window vertical frames are limited in the left-right direction. With the combination of the two structures, the fixed installation between the two door and window horizontal frames and the two door and window vertical frames is realized. When the equipment needs to be disassembled, a hexagonal wrench is inserted into the hexagonal groove to drive the adjusting worm to rotate, forcing the adjusting worm gear meshing with the adjusting worm to drive the positioning rod on the connecting rotating rod to rotate upward and move away from the positioning groove into the guiding chute, releasing the limit of the two door and window horizontal frames and the two door and window vertical frames in the left-right direction. At this time, the two door and window vertical frames can be pulled outwards to drive the four connecting seats away from the two connecting rotating rods, realizing the convenient disassembly operation of the equipment. Similarly, the convenient installation operation of the equipment can be realized through reverse operation. Due to the self-locking function between the adjusting worm gear and the adjusting worm, a positioning effect is formed on the two connecting rotating rods and the four positioning rods thereon, enabling the four positioning rods to be stably clamped in the four positioning grooves. It also enables the staff to perform the loading and unloading operation of the equipment without applying force to the four positioning rods to maintain the positioning. The above operations are simple and practical, with a reasonable and compact structure, realizing the convenient loading and unloading operation of the equipment, improving the stability of the equipment structure, facilitating the staff to perform the loading and unloading operation alone, and enhancing the convenience of using the equipment.

[0016] 2. The metal doors and windows that are convenient for disassembly and assembly are provided with a loading and unloading mechanism. When the equipment is installed by inserting the connecting rotating rod into the connecting jack, when the connecting rotating rod drives the positioning rod to move to the end of the guiding chute, it is exactly aligned with the position inside the positioning groove, that is, the guiding chute can form a limiting and guiding effect on the positioning rod, facilitating the staff to align the positioning rod and the positioning groove, and then facilitating the subsequent installation operation of the equipment. Similarly, during disassembly, the connecting rotating rod rotates to drive the positioning rod to move away from the positioning groove to the end position of the guiding chute, that is, the guiding chute forms a limiting effect on the positioning rod, facilitating the staff to perform the subsequent disassembly operation of the equipment, and further improving the loading and unloading efficiency of the equipment.

An installation and unloading mechanism is arranged between the two door and window horizontal frames 10 and the two door and window vertical frames 11. The installation and unloading mechanism includes two connecting rotating rods 12 rotatably connected to the inside of the two door and window horizontal frames 10 and four connecting seats 13 fixedly installed inside the two door and window vertical frames 11. Installation brackets 14 fixedly installed at corresponding positions on the inner wall surfaces of the two door and window horizontal frames 10 are symmetrically and rotatably connected to the left and right sides of the outer wall surfaces of the two connecting rotating rods 12. The four connecting seats 13 are distributed in a matrix state and correspond to the left and right ends of the two connecting rotating rods 12. Four connecting jacks 15 adapted to the outer wall surfaces of the left and right ends of the two connecting rotating rods 12 are opened on the side of the four connecting seats 13 close to the two connecting rotating rods 12. The left and right ends of the two connecting rotating rods 12 are respectively inserted into the four connecting jacks 15. Guide chutes 16 are penetrated and opened at the top ends of the inner wall surfaces of the four connecting jacks 15 close to the two connecting rotating rods 12. Four positioning card slots 17 communicating with the four guide chutes 16 are penetrated and opened on the side parts of the inner wall surfaces of the four connecting jacks 15. The four guide chutes 16 and the four positioning card slots 17 are arranged perpendicular to each other. Four positioning rods 18 fixedly connected to the corresponding positions on the outer wall surfaces of the two connecting rotating rods 12 are clamped in the four positioning card slots 17. The four guide chutes 16 and the four positioning card slots 17 are all adapted to the four positioning rods 18. An adjusting mechanism for driving the two connecting rotating rods 12 to rotate is arranged in the middle of the inner cavities of the two door and window horizontal frames 10. The adjusting mechanism includes two adjusting worms 20 rotatably connected to the top ends of the middle parts of the inner cavities of the two door and window horizontal frames 10. Two adjusting worm wheels 19 meshing with the two adjusting worms 20 are fixedly installed in the middle parts of the outer wall surfaces of the two connecting rotating rods 12. Two receiving grooves 21 corresponding to the positions of the two adjusting worms 20 are opened on the sides of the two door and window horizontal frames 10 away from each other. The one ends of the two adjusting worms 20 away from each other respectively penetrate the inner wall surfaces of the two door and window horizontal frames 10 and extend into the two receiving grooves 21. Hexagonal grooves 22 are opened on the sides of the two adjusting worms 20 located inside the two receiving grooves 21.

[0024] Working principle of the utility model: In the initial state, both ends of the two connecting and rotating rods 12 are inserted into the four connecting jacks 15 on the four connecting seats 13, so that the two horizontal window and door frames 10 and the two vertical window and door frames 11 are limited in the front-back direction and the up-down direction. Then, the four positioning rods 18 on the two connecting and rotating rods 12 are clamped into the four positioning slots 17 on the two connecting seats 13, so that the two horizontal window and door frames 10 and the two vertical window and door frames 11 are limited in the left-right direction. With the combination of the two structures, the fixed installation between the two horizontal window and door frames 10 and the two vertical window and door frames 11 is realized. When the equipment needs to be disassembled, an Allen wrench is inserted into the hexagonal groove 22 to drive the adjusting worm 20 to rotate, forcing the adjusting worm gear 19 meshing with the adjusting worm 20 to drive the positioning rod 18 on the connecting and rotating rod 12 to rotate upward and move away from the positioning slot 17 and into the guiding chute 16, releasing the limit of the two horizontal window and door frames 10 and the two vertical window and door frames 11 in the left-right direction. At this time, the two vertical window and door frames 11 can be pulled outwards to drive the four connecting seats 13 away from the two connecting and rotating rods 12, realizing the convenient disassembly operation of the equipment. Similarly, the convenient installation operation of the equipment can be realized through reverse operation. Due to the self-locking function between the adjusting worm gear 19 and the adjusting worm 20, a positioning effect is formed on the two connecting and rotating rods 12 and the four positioning rods 18 thereon, so that the four positioning rods 18 can be stably clamped in the four positioning slots 17, and it also enables the staff to perform the loading and unloading operation of the equipment without applying force to the four positioning rods 18 to maintain the positioning. The above operations are simple and practical, with a reasonable and compact structure, realizing the convenient loading and unloading operation of the equipment, improving the stability of the equipment structure, facilitating the staff to perform the loading and unloading operation alone, and improving the convenience of using the equipment; when the equipment is installed by inserting the connecting and rotating rod 12 into the connecting jack 15, when the connecting and rotating rod 12 drives the positioning rod 18 to move to the end of the guiding chute 16, it is exactly aligned with the position in the positioning slot 17, that is, the guiding chute 16 can form a limiting and guiding effect on the positioning rod 18, facilitating the staff to align the positioning rod 18 and the positioning slot 17, and further facilitating the subsequent installation operation of the equipment. Similarly, during disassembly, the connecting and rotating rod 12 rotates to drive the positioning rod 18 to move away from the positioning slot 17 and into the end position of the guiding chute 16, that is, the guiding chute 16 forms a limiting effect on the positioning rod 18, facilitating the staff to perform the subsequent disassembly operation of the equipment and further improving the loading and unloading efficiency of the equipment.
