[0002] Access control intercom door is a security door installed with access control system, which is usually installed at the first floor entrance of high-rise buildings. Due to the rapid development of society and the growth of population, high-rise residential buildings have become common. Therefore, access control intercom door has basically been popularized in most high-rise residential buildings. In addition, due to the rapid development of takeout and express delivery industries, online shopping and ordering takeout have become daily routines. This has led to the residents of high-rise residential buildings needing to frequently open the access control intercom door when picking up takeout or express delivery, and the deliveryman cannot place the express delivery or takeout on the ground in front of the access control door for hygiene reasons. This has led to the deliveryman being unable to enter the access control door to deliver the takeout, and can only wait in front of the door for the resident to open the door to take it. In this process, the deliveryman usually wastes a lot of waiting time, and opening the door to take the takeout or express delivery makes it very inconvenient for the residents, and it is easy for illegal persons to take the opportunity to pass through the access control door. Some existing solutions use lockers with passwords for storage, but the space in the lobby at the unit door is limited and the cost is high. Others are in the unit. If a serving table is placed outside the living room, the user still needs to go out of the building to take it out.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-7 The present invention provides an embodiment of an access control intercom door with an alarm structure for communication, comprising a door frame 1, an access control system 2, a door panel 3 and an emergency alarm 4. The front end of the door frame 1 is fixedly installed with the access control system 2, the door panel 3 is hinged inside the door frame 1, the back end of the door panel 3 is fixedly installed with the emergency alarm 4, the back end of the door panel 3 is installed with a limiting mechanism, a door opening 10 is opened on the door panel 3, the back end of the door frame 1 is fixedly welded with a fixed shaft 11, and the fixed shaft 11 is connected to a rotating sleeve 12 through a bearing sleeve, and the rotating sleeve 12 is equidistant from the front end of the door frame 1. Six groups of hanging rods 13 are welded, and a movable groove 15 is opened on the inner wall of the rotating sleeve 12, and a spring 16 is arranged laterally inside the movable groove 15. A limit block 17 is installed at the opening of the movable groove 15, and the inner end of the limit block 17 is against the end of the spring 16. The outer end of the limit block 17 is set to a hemispherical shape. The outer wall of the fixed shaft 11 is equidistantly opened with six groups of limit grooves 18 that are adapted to the end size of the limit block 17. A guide groove 19 communicating with the movable groove 15 is opened in one group of hanging rods 13, and a tensioning mechanism is installed in the guide groove 19;

[0023] Furthermore, the limiting mechanism includes a fixing seat 5, which is welded to the lower side of the back end of the door panel 3, and a hole is vertically opened in the center of the fixing seat 5, in which a first screw sleeve 6 is fixedly installed, and a first screw rod 7 is vertically inserted into the hole, and the first screw sleeve 6 is adjusted on the first screw rod 7. The lower end of the first screw rod 7 is mounted with a base 8 through a bearing, as shown in FIG. Figure 2 and Figure 5 When the door panel 3 is opened, the structure can limit the door panel 3 by contacting and squeezing the ground, so that the door panel 3 cannot be closed automatically, so that it can remain open for a long time, making it convenient for residents to carry items and other tasks;

[0024] Furthermore, a rubber pad 9 is glued to the lower end of the base 8, and the lower surface of the rubber pad 9 is provided with anti-slip grooves, such as Figure 5 This structure is used to increase the friction generated when the rubber pad 9 contacts the bottom surface, so as to improve the limiting performance;

[0025] Furthermore, the longitudinal section of the hanging rod 13 is circular, and the end of the hanging rod 13 is configured to be hook-shaped, such as Figure 3 This structure prevents the plastic bag from coming into contact with the edges and corners when it is put on the hanging rod 13, thereby avoiding damaging the plastic bag. At the same time, the hook-shaped end can prevent the plastic from slipping off.

[0026] Furthermore, the surface of the hanging rod 13 is provided with ridges 14 at equal intervals, and the ridges 14 are provided in a circular ring shape, such as Figure 4 This structure is used to limit the position of the plastic bag on the hanging rod 13, so that the plastic belt can be staggered and hung on the hanging rod 13, which can avoid the accumulation of plastic belts in the same place and cause inconvenience in taking them out to a certain extent;

[0027] Furthermore, the tensioning mechanism includes a second screw 20, and the guide groove 19 is laterally inserted with the second screw 20. The longitudinal section of the guide groove 19 is square. The outer diameter of one end of the second screw 20 placed in the guide groove 19 is adapted to the inner diameter of the guide groove 19. A top plate 21 is slidably connected in the movable groove 15, and the top plate 21 is fixedly connected to the end of the second screw 20 away from the guide groove 19. A second screw sleeve 22 is installed in the guide groove 19 through a bearing, and the second screw sleeve 22 is sleeved on the second screw 20. A conical gear ring 23 is fixedly sleeved on the second screw sleeve 22. A transmission rod 24 is installed on the hanging rod 13 through a bearing, and a bevel gear 25 is fixedly installed on the inner end of the transmission rod 24. The bevel gear 25 is meshed with the bevel gear ring 23, and the outer end of the transmission rod 24 is fixedly welded with a turning handle 26, as shown in FIG. Figure 2 and Figure 7 This structure is used to adjust the elastic coefficient of the spring 16. By adjusting the tightness of the spring 16, the elastic coefficient of the spring 16 can be changed to adjust the triggering force of the limit block 17. At the same time, it can compensate for the elasticity of the spring 16 that decreases with the increase of use time;

[0028] When in use, the emergency alarm 4 can be used to call for emergency help, and the deliveryman can hang the takeaway or small express delivery through the door opening 10 on the hanging rod 13 behind the door opening 10 after obtaining the consent of the resident. The hook-shaped end of the hanging rod 13 and the convex strip 14 can limit the handle of the plastic belt to prevent the plastic belt from falling from the hanging rod 13, and the convex strip 14 can also separate the plastic belt to a certain extent to prevent the plastic belt from being concentrated together and causing inconvenience in taking. The resident can manually take away his own takeaway or express delivery from the hanging rod 13. During the process, the deliveryman does not need to wait and does not contact each other, which can play a role in mutual protection during the epidemic. There is no need to open the door, which also prevents illegal personnel from taking the opportunity to enter. When the upper and lower groups of hanging rods 13 are in the position of the upper and lower groups of hanging rods 13, the limit block 17 is aligned with the lower group of limit grooves 18. At this time, the spring 16 in the compressed state will push the limit block 17 out through the restorative force, causing the limit block 17 to be embedded in the limit groove 18. In this set of limiting grooves 18, the rotating sleeve 12 is limited at this time, and the hanging rod 13 will remain at the back end of the door opening 10 to wait for use. The elastic force of the spring 16 will decrease with the increase of usage time. At this time, the turning handle 26 can be rotated, so that the turning handle 26 drives the bevel gear 25 to rotate through the transmission rod 24, and the bevel gear 25 drives the second screw sleeve 22 to rotate through the meshing bevel gear ring 23. When the second screw sleeve 22 rotates, it will be threadedly matched with the second screw rod 20. By rotating the turning handle 26, the second screw rod 20 is extended out of the thread action guide groove 19. At the same time, the second screw rod 20 will squeeze the spring 16 away from one end of the limiting block 17 through the top plate 21, causing the spring 16 to be compressed. 16 applies pressure to the limit block 17 through the restorative force. In this way, the elastic coefficient of the spring 16 can be changed to increase the triggering force of the limit block 17 to compensate for the elasticity of the spring 16 that decreases with use. At the same time, when the door panel 3 needs to be opened for a long time to facilitate the transportation of items, the door panel 3 can be opened, and then the first screw 7 is rotated. The first screw 7 drives the base 8 to move downward through the thread cooperation with the first screw sleeve 6 until the rubber pad 9 on the lower surface of the base 8 contacts and fits tightly to the ground. The door panel 3 is limited by extrusion and the friction between the rubber pad 9 and the ground to keep it in the open state for a long time, thereby facilitating people to enter and exit or carry out item transportation. The above is the entire working process of the present invention.

[0029] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein.
