Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1 to 5 This utility model provides a technical solution: a glass splicing unit building door, including a door frame 1 and a door body 2. A connecting plate 3 is welded between the inner walls of the door frame 1. The connecting plate 3 is rotatably connected to the door body 2 via a hinge. The door frame 1 and one side of the outer wall of the door body 2 are rotatably connected by a door closer 4. The door closer 4 is located at the highest point on the surface of the door body 2. A glass mounting groove 5 is opened through the surface of the door body 2. The glass mounting grooves 5 are distributed vertically and are spaced apart by a crossbeam 6. The crossbeam 6 is welded between the inner walls of the door body 2 and forms an integral structure with it. Two connecting plates 3 are provided and are spaced apart by the door body 2. One connecting plate 3 has an access control mounting groove 7 on its surface, and a bulletin board 8 is fixedly connected to the surface of the other connecting plate 3. A protective plate 9 is rotatably connected to the surface of the access control mounting groove 7.

[0025] The glass mounting groove 5 is composed of an inner mounting plate 501 and an outer disassembly plate 502. The inner mounting plate 501 and the groove opened on the surface of the door body 2 form an integral connection. Friction-increasing pads 503 are glued to one side of the outer wall of the inner mounting plate 501 and the outer disassembly plate 502. Tempered glass 504 is tightly attached between the friction-increasing pads 503.

[0026] A protective strip 901 is glued to the side of the protective plate 9 adjacent to the access control installation groove 7. An infrared light strip 902 is fixedly connected between the inner walls of the protective plate 9. A wiring groove 903 is provided above the infrared light strip 902 on the protective plate 9.

[0027] In this embodiment, as Figure 1As shown, the door body 2 and the connecting plate 3 are arranged in pairs and symmetrically distributed about the vertical center line of the door frame 1. The door body 2 forms an opening and closing structure between the connecting plates 3 and below the door frame 1 through hinges. A lock groove is provided between the door bodies 2, and the lock cylinder in the lock groove is electrically connected to the access control system in the access control installation groove 7. As a key connecting component between the door body 2 and the door frame 1, the connecting plate 3 welded to the inner wall of the door frame 1 provides a stable support foundation for the door body 2, allowing the door body 2 to open and close smoothly around the connecting plate 3. The surface of the connecting plate 3 is provided with the access control installation groove 7 and the information board 8, respectively, providing suitable positions for the installation of the access control system and the information board 8. This not only meets the security management needs of the building door, but also provides a platform for information display, making it convenient for residents to obtain information. The structure between the door body 2, the connecting plate 3, and the door frame 1 is compact, realizing the integration of multiple functions in a limited space. This efficient space utilization method is not only suitable for the needs of various different building spaces, but also ensures the smooth passage of people and goods.

[0028] In this embodiment, as Figure 2 As shown, the door closer 4 consists of a connecting rod and a hydraulic rod. One end of the connecting rod is rotatably connected to one end of the hydraulic rod above it, and the other end of the connecting rod and the other end of the hydraulic rod are rotatably connected to the outer walls of the corresponding door body 2 and door frame 1, respectively. The door closer 4 can realize the automatic closing of the door body 2. When the door is opened, under the coordinated action of the hydraulic rod and the connecting rod, the door body 2 can smoothly and slowly return to the closed position. This function greatly facilitates the use of users, eliminating the need for manual closing. It is especially suitable for apartment buildings with frequent personnel entry and exit, effectively maintaining the safety and privacy of the building and preventing unauthorized personnel from entering at will.

[0029] In this embodiment, as Figure 2 and Figure 5 As shown, a cable routing port 10 is provided on one side of the connecting plate 3, and cable delivery ports that communicate with the cable routing port 10 are provided on the inner walls of the access control installation groove 7 and the glass installation groove 5. The cable routing port 10 communicates with the cable delivery ports on the inner walls of each installation groove, providing a unified and orderly wiring channel for all the equipment that needs wiring inside the door 2, such as the access control system and the glass heating device, making the entire wiring system more organized and improving the neatness of the door 2 in appearance.

[0030] In this embodiment, as Figure 3As shown, the friction-increasing pad 503 consists of strip-shaped rubber pads and quadrilateral connectors connecting the rubber pads. The quadrilateral connectors on the surface of the friction-increasing pad 503 and the corners of the outer disassembly plate 502 all have through-holes for threaded cross bolts. The corners of the inner mounting plate 501 also have non-through-holes for threaded cross bolts. Additionally, the side of the friction-increasing pad 503 that contacts the tempered glass 504 has a flared suction cup. The slots through the outer wall of the tempered glass 504 connect with the friction-increasing pad 503. The surface quadrilateral connectors have a consistent structure; the bonding strength of traditional gluing methods is affected by factors such as ambient temperature and humidity, and the glue ages over time, resulting in the glass not being firmly fixed. However, tempered glass 504 is connected to the inner mounting plate 501 and the outer disassembly plate 502 by cross bolts. Combined with the friction of the friction-enhancing pad 503 and the adsorption force of the horn-shaped suction cup, it can provide a strong and durable clamping force, ensuring that tempered glass 504 can be firmly installed under various environmental conditions. This greatly improves the safety and stability of the door 2 and also improves the efficiency of replacement.

[0031] In this embodiment, as Figure 4 As shown, the top and bottom of the crossbeam 6 are tightly connected to the corresponding tempered glass 504, and a heating module is bolted inside the crossbeam 6. Air vents are provided at both the top and bottom of the crossbeam 6. In cold weather or in environments with high humidity, fog or frost is easily formed on the glass surface, which seriously affects visibility and the normal use of the door. When the heating module inside the crossbeam 6 is powered on, heat is discharged through the air vents at the top and bottom. Heat transfer spreads from the edge of the tempered glass 504 to the center, which can effectively dispel fog and frost on the glass surface, keep the glass clear and transparent, ensure visibility inside and outside the door, and provide convenience for residents' daily passage and safety observation. In addition, a maintenance panel is provided on one side of the crossbeam 6, which provides convenience for the maintenance of internal electrical components. At the same time, the outer wall of the crossbeam 6 is made of polycarbonate and the inner wall is made of metal, which can effectively reduce the surface temperature of the crossbeam 6.

[0032] In this embodiment, as Figure 1 and Figure 5As shown, the protective plate 9 forms an openable structure on the surface of the access control mounting slot 7, and the protective plate 9 is connected to the access control mounting slot 7 at one end by a cross bolt thread. The protective plate 9 has two sets of hollow surfaces, one upper and one lower. The upper hollow surface is glued to an acrylic plate of the same material as the bulletin board 8, while the lower hollow surface is a through structure. The protective plate 9 forms an openable structure on the surface of the access control mounting slot 7, which can provide physical protection for the access control system installed in the access control mounting slot 7, reducing the risk of accidental collisions to its visible surface. The lower through hollow surface provides convenience for users to operate the access control system interface. In addition, the protective plate 9 integrates a supplementary lighting function. In the dark or low-light environment, the ordinary access control operation area may be difficult to see, causing inconvenience to users. However, the light emitted by the infrared light strip 902 can illuminate the access control operation interface, allowing users to clearly see the keypad, card swiping area, etc., making it convenient to enter passwords and swipe cards without the need for additional external lighting tools, greatly improving the convenience of users using the access control system at night.

[0033] The usage and advantages of this utility model: The working process of this glass-paneled building entrance is as follows:

[0034] like Figure 1 , Figure 2 , Figure 3 , Figure 4 Figure 5As shown, firstly, the door frame 1 is firmly fixed to the pre-reserved door opening in the building using expansion bolts. The door body 2 is then installed using hinges and connecting plates 3. The door closer 4 assembly is installed at the highest point of the door frame 1 and the door body 2 using pin connectors, with the installation position facing inwards. The door closer 4 is a modular type, with its connecting rod and hydraulic rod fixed by pins to achieve a rotating structure, ensuring that the door body 2 can automatically and smoothly close after opening. Unlike traditional gluing methods, tempered glass 504 is inserted into the glass mounting groove 5. One side of the inner mounting plate 501 is attached to the friction-enhancing pad 503. The outer disassembly plate 502 is threadedly fixed to the inner mounting plate 501 using cross bolts and corresponding slots. During installation, the friction-enhancing pads 503 on the surfaces of the inner mounting plate 501 and the outer disassembly plate 502 gradually apply pressure to both ends of the tempered glass 504, firmly clamping it. The trumpet-shaped suction cup structure on the surface of the friction-enhancing pad 503 will tightly adhere to the tempered glass 504 when the cross bolts are tightened. On both sides of 04, the outer wall of tempered glass 504 has a slot that matches the quadrilateral connector structure of the outer wall of friction-increasing pad 503, so that the cross bolts can effectively avoid contact with tempered glass 504 during installation. An access control system of model NTS-4T01 is installed in the access control installation slot 7. The protective plate 9 forms an opening and closing structure on the surface of the access control installation slot 7. The protective plate 9 and the access control installation slot 7 are connected by cross bolt threads at one end. The protective plate 9 has two sets of hollow surfaces, the upper hollow surface is glued to an acrylic plate of the same material as the bulletin board 8, and the lower hollow surface is a through structure. It is used in conjunction with the access control system of this model. When residents approach the building door, they are identified through the access control system, such as by swiping a card or entering a password. After the access control system successfully identifies the residents, the residents push the door 2. The door 2 rotates around the hinge to open. The linkage and hydraulic rod of the door closer 4 work together to control the opening speed of the door 2.After passing through, door 2 automatically closes under the action of door closer 4. During the day, users can directly operate the access control system interface through the through-hole surface below the protective plate 9. At night, the infrared light strip 902 below the protective plate 9 lights up to provide illumination for the user's operating interface, facilitating access control operations. At the same time, property management personnel can insert relevant information that needs to be notified to residents into the slot of the bulletin board 8 for public display, making it convenient for residents to obtain information. In winter, when the outdoor temperature is low and the temperature difference between indoors and outdoors is large, causing fogging to form on the surface of the tempered glass 504, the heating module inside the beam 6 can be activated. After the heating module is powered on, heat is discharged from the air vents at the top and bottom of the crossbeam 6. Heat transfer spreads from the edge of the tempered glass 504 to the center, alleviating fogging on the glass surface and maintaining the clarity of the glass. When maintenance and repair of the access control system are required, relevant personnel only need to remove the cross bolts corresponding to the surface of the protective plate 9 and the access control mounting groove 7, open the protective plate 9, and the access control system can be repaired. If the tempered glass 504 needs to be replaced, unscrew the cross bolts between the outer disassembly plate 502 and the inner mounting plate 501, and the old glass can be removed and replaced with a new tempered glass 504.
