[0002] With the rapid development of modern urban construction and the significant improvement of people's quality of life, buildings are not only required to be sturdy and durable, but also pursue the perfect integration of artistry and practicality. Especially in terms of safety facilities such as fire protection, people hope that they can not only provide security, but also be beautiful and practical, and conform to the overall decoration style. Therefore, many buildings take this into consideration when designing, and the finishing of safety facilities such as finished fire hidden doors is decorated simultaneously with the wall engineering, so that the finished fire hidden doors and wall decoration are integrated, which is not only beautiful and generous, but also has a variety of decorative styles, meeting people's aesthetic needs.

[0003] However, as the building is used for a long time and the frequency of opening and closing of the hidden door increases, some problems are gradually exposed. Due to the frequent opening and closing of the hidden door, its stability gradually deteriorates, resulting in unevenness between the hidden door and the wall decoration, and the hidden door is no longer tight when closed. These problems seriously affect the overall decoration effect, making the originally beautiful wall decoration look messy.

The other side of the door leaf 400 is closely matched with the door bump, so that when the door leaf 400 is closed, the door bump can ensure that the door leaf 400 is closely attached to the decorative wall surface 100, achieving a good sealing effect. During the installation and connection process of the door leaf 400 and the door post 300, the blocking member 700 provided on the door post 300 can penetrate into the small gap between the door leaf 400 and the door opening 110, effectively blocking and blocking the gap between the door leaf 400 and the door opening 110. This design not only ensures the close fit between the door leaf 400 and the decorative wall surface 100, but also effectively prevents foreign matter such as dust and microorganisms from invading between the decorative wall surface 100 and the original building wall surface, thereby ensuring the cleanliness of the wall surface and the overall safety of the building.

[0039] In actual use, the operation of the finished fire-fighting hidden door is extremely convenient and durable. In the initial state, the end face of the door leaf 400 away from the original building wall 200 is kept flush with the decorative wall surface 100, ensuring the aesthetics of its overall decorative effect. When it is necessary to open the finished fire-fighting hidden door, just press the side of the door leaf 400 close to the door touch, so that the door leaf 400 swings in the direction close to the original building wall 200, and the door touch can be triggered to return to the top. At this time, an angle will appear between the door leaf 400 and the decorative wall surface 100, forming a door gap. The user only needs to put his hand deep into the door gap and gently move the door leaf 400, so that the door leaf 400 can swing relative to the connecting hinge 500, so as to fully open the door leaf 400. In addition, since a blocking member 700 is provided between the door leaf 400 and the decorative wall surface 100, when the door leaf 400 is in a closed state, it can ensure that the gap between the door leaf 400 and the door opening 110 is completely blocked and blocked. This not only prevents foreign matter such as dust and microorganisms from invading between the decorative wall surface 100 and the original building wall surface, but also effectively prevents the connecting hinge 500, the door stop and other components from being contaminated and corroded by foreign matter. This design not only prolongs the service life of the finished fire-fighting hidden door, but also ensures that it can work normally and reliably at critical moments.

[0040] In some embodiments, the door column 300 includes a fixing plate 310, an L-shaped connecting plate 320, and a keel 330. The fixing plate 310 is installed on the original building wall 200. The horizontal plate 321 of the L-shaped connecting plate 320 is fixedly connected to the fixing plate 310. The longitudinal plate 322 of the L-shaped connecting plate 320 is fixedly connected to the keel 330. The keel 330 is installed on the end surface of the decorative wall 100 close to the original building wall 200. The keel 330 extends along the decorative wall 100 toward the door opening 110 to form a supporting portion 331. The blocking member 700 is installed on the supporting portion 331. Specifically, each of the above parts The components are connected and fixed by screws. By fixing the door post 300 to the original building wall 200 and the decorative wall 100 at the same time, on the one hand, the fixing reliability of the door post 300 is ensured and the probability of the door post 300 being deflected is reduced. On the other hand, support can be provided for the relative position of the decorative wall 100 and the original building wall 200 to ensure the connection stability between the various components. The supporting portion 331 protruding from the decorative wall 100 and provided on the keel 330 can provide reliable support and limitation for the door leaf 400 to avoid the door leaf 400 from buckling inward when it approaches the original building wall 200, thereby affecting its normal use.

[0041] In some embodiments, the connecting hinge 500 and the door stop are respectively installed on the supporting portion 331 of the corresponding keel 330. By installing the connecting hinge 500 on the protruding supporting portion 331, the swinging direction of the door leaf 400 relative to the connecting hinge 500 is increased, and the opening angle of the door leaf 400 can be effectively increased, so that after the door leaf 400 is opened, there is a maximum angle of 160° between the door leaf 400 and the decorative wall 100, which makes it more convenient for users to take and place fire-fighting equipment through the door opening 110.

[0042] In some embodiments, the blocking member 700 includes a blocking end 710 and a clamping end. A clamping groove corresponding to the clamping end is provided on the end surface of the support portion 331 close to the door leaf 400, and the clamping end is installed in the clamping groove. The blocking end 710 is passed between the door leaf 400 and the decorative wall 100. By setting the clamping structure, when installing the blocking member 700, the clamping end can be directly inserted into the clamping groove, which is easy to operate. Moreover, when the blocking effect of the blocking member 700 on the gap between the door leaf 400 and the door opening 110 is reduced due to long-term use, the blocking member 700 can be quickly disassembled and replaced for easy maintenance.

[0043] In some embodiments, the snap-in slot includes two symmetrical triangular slots 332, and the snap-in end includes two symmetrically arranged snap-in plates 720; the snap-in end is installed in the snap-in slot, and the snap-in plate 720 abuts against the corresponding triangular slot 332; specifically, Figure 2 As shown, after the snap-in end is installed in the snap-in groove, the snap-in plate 720 can always abut against the corner of the corresponding triangular groove 332, thereby forming a stable fit, which can effectively prevent the blocking member 700 from shaking randomly.

[0044] In some embodiments, the blocking end 710 of the blocking member 700 is arranged in the gap between the door leaf 400 and the decorative wall surface 100; that is, when the blocking end 710 of the blocking member 700 penetrates into the gap between the door leaf 400 and the decorative wall surface 100, it is at most flush with the end surface of the decorative wall surface 100 away from the original building wall 200, so as to avoid affecting the flatness of the decorative wall surface 100.

[0045] In some embodiments, the door touch includes a rebounder 610, which is installed on the corresponding door column 300. Pressing the movable rod 611 of the rebounder 610 can make it approach the door leaf 400 to push the door leaf 400; when the user needs to open the door leaf 400, just press the door leaf 400 lightly, and then press the movable rod 611 of the rebounder 610, the movable rod 611 will respond quickly and move toward the door leaf 400. This push action can effectively help the door leaf 400 overcome possible resistance and achieve smooth opening. The design principle of the rebounder 610 is very intuitive and easy to understand. Through a simple mechanical structure and power transmission mechanism, it can achieve fast and accurate action response. This design not only ensures the efficiency of the door touch device, but also greatly simplifies the installation process. Whether it is a professional installer or a user with certain hands-on ability, it can easily complete the installation of the rebounder 610. In addition, the maintenance of the rebounder 610 is also quite convenient. Due to its simple structure and few parts, daily inspection and maintenance are relatively simple. Even when a fault occurs, users can quickly locate the problem and repair it, or contact professionals for maintenance. This convenience makes the door contact device more reliable during use and provides users with a better experience.

[0046] In some embodiments, a first connecting member is provided on the movable rod 611, and a second connecting member corresponding to the first connecting member is provided on the end surface of the door leaf 400 close to the movable rod 611, and the first connecting member is correspondingly connected to the second connecting member; when the door leaf 400 remains closed, the corresponding connection between the first connecting member and the second connecting member can effectively avoid the accidental opening of the door leaf 400 due to external factors such as vibration or wind, thereby ensuring the reliability of the door leaf 400 in a closed state.

[0047] In some embodiments, the first connecting member is an elastic connecting seat 620, and a ball groove 621 is provided on the elastic connecting seat 620. The second connecting member is a rigid connecting seat 630, and a connecting ball 631 is provided on the rigid connecting seat 630. When the connecting ball 631 approaches the ball groove 621 and enters the ball groove 621, the ball groove 621 is squeezed and expanded, and finally the connecting ball 631 falls into the ball groove 621, so that the elastic connecting seat 620 is connected to the rigid connecting seat 630, and the door leaf 4 When 00 is pulled by an external force greater than the elastic force caused by the ball groove 621 on the connecting ball 631, the elastic connecting seat 620 and the rigid connecting seat 630 can be quickly separated, so that the door leaf 400 can be quickly opened, so that the corresponding connection between the first connecting member and the second connecting member will not affect the opening and closing of the door leaf 400, and the principle is simple, which is convenient for later replacement and maintenance; of course, in other embodiments of the utility model, the door leaf 400 can also be connected to the movable rod 611 by adopting other structures.

[0048] In some embodiments, the material selection of the doorpost 300 takes into special consideration its durability, corrosion resistance and cost-effectiveness. Therefore, the doorpost 300 is made of galvanized steel. This material not only has extremely high strength and stability, and can withstand various pressures and impacts that may be encountered in daily use, but also its surface is galvanized, which can effectively resist oxidation and corrosion, thereby extending the service life of the doorpost 300. In addition, the galvanized steel material also has good plasticity, and can be processed and customized according to actual needs to meet the use requirements in different occasions and environments. The selection of this material not only ensures the reliability and durability of the doorpost 300, but also takes into account cost-effectiveness, and is an ideal material for the doorpost 300.

[0049] In some embodiments, the end surface of the door column 300 close to the door leaf 400 is paved with a buffer layer 340. The main function of this buffer layer 340 is to effectively reduce shock and buffer the door leaf 400 during the opening and closing process of the door leaf 400, especially at the moment when the door leaf 400 is about to be completely closed or just opened. Specifically, when the door leaf 400 contacts the buffer layer 340 of the door column 300 during the closing process, the buffer layer 340 will absorb part of the impact force, reduce the collision sound between the door leaf 400 and the door column 300, and also prevent the door leaf 400 from being damaged by direct impact. Similarly, at the moment when the door leaf 400 is opened, the buffer layer 340 can also play a similar role to ensure that the door leaf 400 is opened smoothly and smoothly. Such a design not only improves the comfort of the door leaf 400, reduces noise, but also prolongs the service life of the door leaf 400 and the door column 300. The material of the buffer layer 340 is usually selected from a material with certain elasticity and wear resistance to ensure that it is durable and has a good shock absorption effect.
