Description

Technical Field

[0001] The present application relates to the technical field of fireproof windows, and in particular to an elastic locking device for fireproof windows. Background Art

[0002] At present, the common fireproof windows on the market mainly use mechanical locking devices to achieve closure and sealing, so as to ensure that they can effectively isolate the spread of fire in the event of a fire. These devices mostly use fasteners such as bolts and nuts, and are installed and removed by manual or power tools. Among them, a relatively advanced existing technology is to use a spring-loaded locking mechanism, which can improve the sealing and locking efficiency of the window sash to a certain extent. However, this type of device still has some problems in practical application. Once the locking device of the existing fireproof window is damaged or requires maintenance, it usually requires professionals to use specific tools to remove it. The process is cumbersome and time-consuming, which is not conducive to rapid replacement in an emergency. The design of some devices makes it difficult for users to quickly open or close the fireproof window in an emergency, increasing safety hazards.

[0003] The above information disclosed in this background technology is only used to increase the understanding of the background technology of this application. Therefore, it may contain information that does not constitute the prior art known to ordinary technicians in this field. Utility Model Content

[0004] In order to solve the problem that once the locking device of the existing fireproof window is damaged or needs maintenance, it usually requires professionals to use specific tools to disassemble it. The process is cumbersome and time-consuming, which is not conducive to rapid replacement in an emergency. The design of some devices makes it difficult for users to quickly open or close the fireproof window in an emergency, increasing safety hazards. The present application provides an elastic locking device for fireproof windows.

[0005] The elastic locking device for a fireproof window provided in this application adopts the following technical solution:

[0006] An elastic locking device for a fireproof window comprises a shell, two limit plates are arranged in the shell, a fireproof window body is arranged above the shell, horizontal plates are arranged on the front and back sides of the fireproof window body, and the shell is connected to the fireproof window body through a connecting mechanism.

[0007] Preferably, the connecting mechanism includes a cavity opened on the front side of the shell, the cavity is used to place the fireproof window body, a sliding groove is opened between the left and right inner walls of the shell, and a placement groove is opened on the inner bottom of the shell, and the two sliding grooves and the placement groove are connected to the cavity.

[0008] Preferably, a connecting block is slidably connected between the front and rear inner walls of the two slides, and the two connecting blocks are wedge-shaped blocks. The ends of the two connecting blocks away from the cavity are elastically connected to the inner walls of the corresponding slides through compression springs.

[0009] Preferably, one end of the two connecting blocks away from the cavity is fixedly connected to a pull rod, and the other end of the two pull rods extends to one side of the shell and is fixedly connected to a buckle.

[0010] Preferably, wedge-shaped grooves that cooperate with the connecting blocks are provided on the left and right sides of the fireproof window body, and a top plate is slidably connected between the left and right inner walls of the placement groove, and the top plate is elastically connected to the inner bottom of the placement groove through multiple connecting springs.

[0011] In summary, this application has the following beneficial technical effects:

[0012] 1. When the fireproof window body needs to be replaced, just pull the two pull buckles. This action will cause the two pull rods to move in opposite directions, which in turn drives the two connecting blocks out of the corresponding slide slots. Subsequently, under the elastic force of multiple connecting springs, the top plate will quickly rise, realizing the rapid separation of the two fixed structures. In this way, the disassembly process is completed, allowing non-professionals to quickly unlock with simple operations, facilitating rapid opening or replacement in emergency situations.

[0013] 2. During installation, align the fireproof window body directly with the cavity and snap it in. As the fireproof window body moves downward, the two wedge-shaped connecting blocks will move to both sides. When the fireproof window body drops to the position where the connecting block is facing the slide groove, the connecting block will automatically snap into the slide groove to complete the limit. The whole process is simple and fast, and no tools are required, whether it is disassembly or installation. After installation, the top plate is pressed down by the fireproof window body, and the connecting spring is compressed accordingly. Under the elastic force of the spring, the top plate will give the fireproof window body an upward force, which works together with the limit of the connecting block to ensure that the fireproof window body can maintain a good locking force under different environmental conditions.

[0018] The following is combined with Figure 1-3This application is described in further detail.

[0019] The embodiment of the present application discloses an elastic locking device for fireproof windows. Figure 1-3 A resilient locking device for a fireproof window comprises a shell 1, two limit plates 13 are arranged in the shell 1, a fireproof window body 6 is arranged above the shell 1, and horizontal plates 14 are arranged on the front and rear sides of the fireproof window body 6. The shell 1 is connected to the fireproof window body 6 through a connecting mechanism.

[0020] When the fireproof window body 6 needs to be replaced, it is only necessary to pull the two pull buckles 2. This action will cause the two pull rods 11 to move in opposite directions, thereby driving the two connecting blocks 5 to disengage from the corresponding slide grooves 10. Subsequently, under the elastic force of multiple connecting springs 9, the top plate 8 will rise rapidly, realizing the rapid separation of the two fixed structures. In this way, the disassembly process is completed, allowing non-professionals to quickly unlock it through simple operations, which is convenient for rapid opening or replacement in emergency situations.

[0021] Reference Figure 2-3 The connecting mechanism includes a cavity 3 opened on the front side of the shell 1, a fixed plate is provided between the cavity 3 and the two limit plates 13, the cavity 3 is used to place the fire window body 6, a slide groove 10 is opened between the left and right inner walls of the shell 1, and a placement groove 4 is opened at the inner bottom of the shell 1. The two slide grooves 10 and the placement groove 4 are connected to the cavity 3, and a connecting block 5 is slidably connected between the front and rear inner walls of the two slide grooves 10. The two connecting blocks 5 are wedge-shaped blocks, and the ends of the two connecting blocks 5 away from the cavity 3 are elastically connected to the inner walls of the corresponding slide groove 10 through compression springs 12. The ends of the two connecting blocks 5 away from the cavity 3 are fixedly connected to a pull rod 11, and the other ends of the two pull rods 11 extend to one side of the shell 1 and are fixedly connected to a buckle 2.

[0022] Align the fireproof window body 6 directly with the cavity 3 and snap it in. As the fireproof window body 6 moves downward, the two wedge-shaped connecting blocks 5 will move to both sides. When the fireproof window body 6 drops to the position where the connecting block 5 is facing the slide groove 10, the connecting block 5 will automatically snap into the slide groove to complete the limiting. The whole process is simple and quick, and no tools are required, whether it is disassembly or installation.

[0023] Reference Figure 1-3 The left and right sides of the fireproof window body 6 are provided with wedge-shaped grooves 7 that cooperate with the connecting block 5. A top plate 8 is slidably connected between the inner walls on the left and right sides of the placement groove 4. The top plate 8 is elastically connected to the inner bottom of the placement groove 4 through multiple connecting springs 9.

[0024] The implementation principle of the elastic locking device of the fireproof window in the embodiment of the present application is as follows: when the fireproof window body 6 needs to be replaced, it is only necessary to pull the two pull buckles 2. This action will cause the two pull rods 11 to move in opposite directions, thereby driving the two connecting blocks 5 to disengage from the corresponding sliding grooves 10. Subsequently, under the elastic force of multiple connecting springs 9, the top plate 8 will rise rapidly, realizing the rapid separation of the two fixed structures. In this way, the disassembly process is completed, allowing non-professionals to quickly unlock the window through simple operations, which is convenient for rapid opening or replacement in emergency situations.

[0025] During installation, align the fireproof window body 6 directly with the cavity 3 and snap it in. As the fireproof window body 6 moves downward, the two wedge-shaped connecting blocks 5 will move to both sides. When the fireproof window body 6 drops to the position where the connecting block 5 is facing the slide groove 10, the connecting block 5 will automatically snap into the slide groove to complete the limit. The whole process is simple and fast, and no tools are required, whether it is disassembly or installation. After installation, the top plate 8 is pressed down by the fireproof window body 6, and the connecting spring 9 is compressed accordingly. Under the elastic force of the spring, the top plate 8 will give the fireproof window body 6 an upward force, which will work together with the limit of the connecting block 5 to ensure that the fireproof window body 6 can maintain a good locking force under different environmental conditions.
