Description

Technical Field

[0001] This utility model relates to the field of door and window technology, and in particular to a self-locking device for door and window installation. Background Technology

[0002] As a key component of the building envelope, doors and windows serve a dual function of enclosure and spatial division, depending on their location within the building. Therefore, their design must meet specific functional requirements, such as thermal insulation, sound insulation, waterproofing, and fire resistance, all of which must be guaranteed through systematic technical measures. As the core element of the building envelope, the functional design of doors and windows has a crucial impact on the overall performance of the building.

[0003] Chinese Patent CN219158665U discloses an automatic door and window locking device, including a window frame and a first and second door / window disposed inside the window frame. The first door / window has a locking mechanism comprising a fixed frame fixedly mounted on its surface, a first pressing rod movably mounted inside the fixed frame via a first spring, second pressing rods movably mounted on both sides of the first pressing rod via second springs, and a latching rod movably mounted on one side of the second pressing rod via a third spring. This locking mechanism uses an internally designed latching rod and latching block to lock the first and second doors / windows. The latching rod is supported by a third spring on one side, providing sufficient support and improving the stability of the locking mechanism, preventing loosening and ensuring a more secure lock on the first and second doors / windows.

[0004] However, the above technical solution has the following shortcomings: Although the door and window can lock the first and second doors and windows through the locking mechanism, multiple springs with different functions are installed inside to act simultaneously, driving multiple compression rods and locking rods to engage, which greatly increases the probability of problems with the locking mechanism and also increases the difficulty of maintenance. Utility Model Content

[0006] The technical solution of this utility model is a door and window self-locking device, including an installation frame and a self-locking mechanism; two rotating frames are rotatably connected to the installation frame, and transparent glass sheets are provided on the rotating frames; the self-locking mechanism includes a first fixed block and a second fixed block respectively disposed on the two rotating frames, a slider slidably connected to the second fixed block and having a second inclined surface, two springs disposed inside the second fixed block, and two guide blocks symmetrically distributed on the slider; the first fixed block has a first inclined surface, and a limiting groove for the end of the guide block to be embedded in the first fixed block; the two ends of the spring are respectively on the second fixed block and the slider; and a sliding groove for the guide block to slide horizontally is provided inside the second fixed block.

[0007] Preferably, hinges are provided on the mounting frame and the rotating frame.

[0008] Preferably, the slider is provided with two horizontally distributed stabilizing rods that are slidably connected to the second fixed block, and the springs are sleeved on the stabilizing rods.

[0009] Preferably, the slider is provided with a connecting block, and the connecting block is provided with a pull plate.

[0012] Preferably, the rotating frame is provided with a cleaning mechanism, which includes a lifting plate, a mounting plate on the lifting plate, a cleaning pad on the mounting plate, and two third bolts that pass through the lifting plate and are threaded to the mounting plate; a handle is provided on the lifting plate.

[0013] Preferably, a fixed frame is provided on the rotating frame, and vertically distributed guide rods are provided inside the fixed frame. The lifting plate is slidably connected to the guide rods and slidably connected to the fixed frame.

[0014] Compared with the prior art, the present invention has the following beneficial technical effects:

[0015] This utility model achieves a self-locking function when doors and windows are closed through a self-locking mechanism. The locking effect is stable, and the structure of the self-locking mechanism is simple, which not only reduces the probability of failure but also facilitates installation and maintenance.

[0021] Example 1

[0022] like Figures 1-4 As shown in the figure, the self-locking device for door and window installation proposed in this embodiment includes an installation frame 1 and a self-locking mechanism; two rotating frames 2 are rotatably connected to the installation frame 1, and hinges 3 are provided on the installation frame 1 and the rotating frames 2, and transparent glass sheets 4 are provided on the rotating frames 2.

[0023] The self-locking mechanism includes a first fixed block 5 and a second fixed block 6 respectively disposed on two rotating frames 2, a slider 8 slidably connected to the second fixed block 6 and having a second inclined surface 9, two springs 10 disposed inside the second fixed block 6, and two guide blocks 11 symmetrically distributed on the slider 8; the first fixed block 5 has a first inclined surface 7, and the first fixed block 5 is provided with a limiting groove for the end of the guide block 11 to be embedded in; the two ends of the spring 10 are respectively on the second fixed block 6 and the slider 8; the interior of the second fixed block 6 is provided with a sliding groove for the guide block 11 to slide horizontally.

[0024] A connecting block 13 is provided on the slider 8, and a pull plate 14 is provided on the connecting block 13.

[0025] The slider 8 is provided with two horizontally distributed stabilizing rods 12 that are slidably connected to the second fixed block 6. The spring 10 is sleeved on the stabilizing rod 12. The stabilizing rod 12 is used to guide the extension and retraction of the spring 10, so as to prevent the spring 10 from being completely twisted and to ensure the service life of the spring 10.

[0026] In this embodiment, when the doors and windows are closed, the hinge 3 rotates the rotating frame 2, which in turn causes the transparent glass sheet 4 to close. When the second inclined surface 9 of the slider 8 contacts the first inclined surface 7 on the first fixed block 5, compression occurs. Subsequently, the slider 8 slides along the groove into the first fixed block 5 under the action of the guide block 11. At the same time, the spring 10 is compressed. When the first inclined surface 7 and the second inclined surface 9 are completely misaligned, the slider 8 slides outward under the elastic force of the spring 10 until the end of the slider 8 is completely embedded in the limiting groove on the first fixed block 5, thus completing the self-locking of the two rotating frames 2. When it is necessary to open the doors and windows, the pull plate 14 pulls the connecting block 13, which causes the slider 8 to slide until the slider 8 disengages from the limiting groove, thus opening the doors and windows. This method is not only simple and convenient to use, but also has a simple structure, making it easy to assemble and maintain.

[0027] Example 2

[0028] like Figure 2 and Figure 3 As shown in the figure, the door and window self-locking device proposed in this embodiment, compared with the first embodiment, has two fixing plates 15 on both the first fixing block 5 and the second fixing block 6, and two first bolts 16 are threadedly connected to the rotating frame 2 on the fixing plate 15.

[0029] A sealing plate 17 is provided on the second fixing block 6, and two second bolts 18 are threadedly connected to the second fixing block 6 through the sealing plate 17.

[0030] In this embodiment, the self-locking mechanism can be quickly installed on the rotating frame 2 by means of the fixed plate 15 and the first bolt 16. The sealing plate 17 is used to isolate and protect the internal structure of the second fixed block 6. At the same time, the sealing plate 17 can be disassembled by the second bolt 18, so that it is easy to repair or replace when the self-locking mechanism has a problem.

[0031] Example 3

[0032] like Figure 1 and Figure 4 As shown, this embodiment proposes a door and window self-locking device. Compared with the first embodiment, in this embodiment, the rotating frame 2 is provided with a cleaning mechanism. The cleaning mechanism includes a lifting plate 20, a mounting plate 21 provided on the lifting plate 20, a cleaning pad 22 provided on the mounting plate 21, and two third bolts 23 that penetrate the lifting plate 20 and are threadedly connected to the mounting plate 21. A handle 24 is provided on the lifting plate 20, and a fixed frame 19 is provided on the rotating frame 2. Vertically distributed guide rods 25 are provided inside the fixed frame 19. The lifting plate 20 is slidably connected to the guide rods 25 and slidably connected to the fixed frame 19.

[0033] In this embodiment, when it is necessary to clean the transparent glass sheet 4 or remove impurities from its surface, the cleaning liquid is first sprayed onto the transparent glass sheet 4. The lifting plate 20 is pulled up and down by the handle 24, and the lifting plate 20 drives the mounting plate 21 to move, thereby allowing the cleaning pad 22 to clean the transparent glass sheet 4. The mounting plate 21 can be disassembled by the third bolt 23 so that the cleaning pad 22 can be cleaned or replaced after long-term use.

[0034] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
