Description

Technical Field

[0001] The utility model relates to the technical field of door and window connection mechanisms, and specifically relates to a connection structure for manufacturing metal doors and windows. Background Technique

[0002] According to the material of the doors and windows, they can be divided into plastic-steel (PVC) doors and windows, aluminum alloy doors and windows, solid wood doors and windows, and stainless steel doors and windows; doors and windows are an indispensable part of a living room. So far, doors and windows have gone through four eras: wooden, steel, aluminum alloy, and plastic-steel doors and windows. Wooden doors and windows have a moderate price, poor sealing performance, are flammable, prone to deformation and cracking, can only be used in general places, have high maintenance costs, and a short service life.

[0003] In the prior art, such as a rivet connection structure for a metal door leaf in CN215565452U, a rivet connection structure for a metal door leaf is provided. Sliding grooves are opened on both the second metal plate and the first metal plate. Two metal rings are inserted into the sliding grooves on the two metal plates. When assembling, two limiting blocks are inserted into the circular notch and the round hole. After the metal plates and metal rings on both sides are spliced, the limiting blocks will ensure that the two metal plates cannot move up, down, left, or right. Then, a rivet gun is used to drive rivets into eight fixing grooves, and both hands are used to pull the handle forcefully until the nail rod is broken, and the riveting is completed, and the metal door leaf is spliced. When disassembly is required, the eight rivets are pulled out by tools, and then the door leaf can be disassembled. In this way, if a component inside is damaged, it can be replaced separately, and when the door leaf is transported, it can be disassembled into multiple parts for transportation, and then spliced after arriving at the destination, so the transportation is also very convenient.

[0004] However, there are still certain problems when using the above and other typical prior arts; this mechanism completely loses the ability to move. To add the effect of movement, the cost is greatly increased. Moreover, this mechanism is fixed by rivets. This fixing method is not only quite complicated and cumbersome to operate, but also very time-consuming and laborious, bringing a lot of inconvenience to the relevant staff, greatly increasing their work difficulty and workload.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] Next, in combination with the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the protection scope of the present invention.

[0024] For the embodiments, please refer to Figures 1-4 , the present invention provides a technical solution:

[0025] A connecting structure for manufacturing metal doors and windows, including a door frame 1 and a door panel 17. The door frame 1 is provided with a first groove 2. An installation plate 3 is fixedly connected to the outside of the first groove 2. The installation plate 3 is provided with a cross-shaped sliding groove 4. A first fixing block 5 is fixedly connected to the outside of the cross-shaped sliding groove 4. A first connecting column 7 and a second connecting column 8 are respectively fixedly connected to the top of the first fixing block 5. The top of the second connecting column 8 is rotatably connected to a first connecting plate 9. One end of the first connecting plate 9 is rotatably connected to the second connecting column 8 and the other end is fixedly connected to a first rotating rod 10. A support plate 11 is rotatably connected to the outside of the first rotating rod 10. A connecting member 12 is fixedly connected to the center of the support plate 11. A slider 6 is slidably connected to the inside of the cross-shaped sliding groove 4. A third connecting column 13 is fixedly connected to the top of the slider 6. The top of the third connecting column 13 is rotatably connected to a second connecting plate 14. One end of the second connecting plate 14 is rotatably connected to the third connecting column 13 and the other end is rotatably connected to the connecting member 12. A third connecting plate 15 is rotatably connected to the outside of the first connecting column 7. One end of the third connecting plate 15 is rotatably connected to the first connecting column 7 and the other end is rotatably connected to a second rotating rod 16. The door panel 17 is provided with a second groove 27. The support plate 11 is fixedly connected to the second groove 27.

[0026] Among them, within the installation plate 3, the first fixing block 5 and the slider 6 cooperate with each other. When the door panel 17 needs to be opened, relying on the force generated by the movement of the slider 6, it can efficiently drive the second connecting plate 14, and then pull the support plate 11 and the third connecting plate 15 to move accordingly. As the second connecting plate 14 moves, it will also indirectly push the first connecting plate 9 to displace. Such a precisely cooperating transmission mechanism can effectively achieve the opening and closing.

[0027] In this embodiment, as Figures 1-4As shown, a fixed cylinder 18 is fixedly connected to the outside of the door panel 17. A push rod 19 is slidably connected to the inside of the fixed cylinder 18. A spring 21 is elastically connected to the outside of the push rod 19. A limiting plate 20 is fixedly connected to the outside of the push rod 19. One end of the spring 21 is elastically connected to the fixed cylinder 18 and the other end is elastically connected to the limiting plate 20. One end of the push rod 19 is fixedly connected to a handle 22 and the other end is fixedly connected to a rectangular block 23. A damping rod is arranged inside the spring 21. A second fixed block 24 is fixedly connected to the outside of the door frame 1. The second fixed block 24 is provided with a card slot 25 and a jack 29. The card slot 25 is clamped with the rectangular block 23. A T-shaped plug rod 26 is inserted into the jack 29. The T-shaped plug rod 26 extends into the rectangular block 23. A handle 28 is fixedly connected to the outside of the door panel 17. The handle 28 is U-shaped.

[0028] Among them, when the door panel 17 needs to be closed, pull the handle 28 and use the first fixed block 5 as a fixed point to achieve the closing effect by the precise cooperation of each component. Then push the handle 22 to drive the push rod 19, so that the rectangular block 23 is clamped into the card slot 25. Finally, insert the T-shaped plug rod 26 into the jack 29 and extend it into the rectangular block 23, which reduces the working time and has a very convenient and simple opening and closing effect.

[0029] The working process of the present utility model: When the door panel 17 needs to be opened, first, the T-shaped plug rod 26 must be pulled out. Then, pull the handle 22 to drive the push rod 19, so that the rectangular block 23 is disengaged from the second fixed block 24. Then push the door panel 17. Since the door panel 17 is fixedly connected to the support plate 11, the first fixed block 5 and the slider 6 in the mounting plate 3 can be relied on to cooperate with each other. By means of the movement of the slider 6, the second connecting plate 14 is driven, and then the support plate 11 and the third connecting plate 15 are driven to move accordingly. Since the first fixed block 5 is fixedly connected in the cross-shaped chute 4 and only the slider 6 can slide, finally the effect of driving the door panel 17 to open is achieved. When the door panel 17 needs to be closed, pull the handle 28 and use the first fixed block 5 as a fixed point to achieve the closing effect through the precise cooperation of each component. Then, push the handle 22 to drive the push rod 19 to make the rectangular block 23 clamped into the card slot 25. Finally, insert the T-shaped plug rod 26 into the jack 29 and extend it into the rectangular block 23 to complete the operation.

[0030] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
