DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process.

[0020] When using traditional access control, most of them use access control with non-adjustable door beams. This requires that when installing the access control, the precise size of the access control needs to be measured in advance, and then the access control is produced according to the size, and then the access control is installed, which increases the time cost;

[0021] In view of this, the utility model provides an access control structure that can adapt to different installation widths. The access control structure that can adapt to different installation widths solves the problem that traditional access control requires precise measurement of dimensions during installation, which increases time costs, through an adjustment device. The length of the door beam can be changed by using the adjustment device, and precise measurement is not required in the early stage. After production, it can be suitable for access control use in different scenarios. Automatic opening and closing of the access control can be achieved through a rotating device and a telescopic device, thereby reducing labor costs.

[0022] Embodiment 1: Figure 1 ,2 , 3 and 4 show that a door access structure adaptable to different installation widths includes a crossbeam 1, a first support leg 2 is installed at the bottom of the crossbeam 1, and the door access structure adaptable to different installation widths also includes: an adjustment device 3, installed above the first support leg 2; a rotating device 4, arranged below the crossbeam 1; a telescopic device 5, installed on the outer wall of the first support leg 2; a protective device 6, installed on the outside of the telescopic device 5; the adjustment device 3 can change the distance between the crossbeam 1 and the adjustment device 3, the first support leg 2 supports the crossbeam 1, and the protective device 6 can reduce the damage caused by collision to pedestrians and door access; wherein the adjustment device 3 can adjust the overall width of the door access structure adaptable to different installation widths, the rotating device 4 can rotate the telescopic device 5, the telescopic device 5 can adapt to the switch of the door access structure of different installation widths, and the protective device 6 can protect the door access structure adaptable to different installation widths;

[0023] In the specific implementation process, it is worth pointing out that the adjustment device 3 can change the distance between the crossbeam 1 and the adjustment device 3, the first leg 2 supports the crossbeam 1, and the protection device 6 can reduce the damage caused by the collision to pedestrians and access control;

[0024] Specifically, when using the access control structure that can adapt to different installation widths, before the access control is used, the staff will first install the access control. The distance between the beam 1 and the adjustment device 3 can be changed through the adjustment device 3. When the distance is adjusted to a suitable position, the worker will install the access control structure that can adapt to different installation widths. After the installation is completed, it can be put into use. When pedestrians come to the access control, the access control card can be used to make the telescopic device 5 retract, so as not to block the pedestrians. When the number of pedestrians is large, the access control can be fully opened by using the rotating device 4 in conjunction with the telescopic device 5, so that more pedestrians can pass through the access control.

[0025] Embodiment 2: By Figure 1 and 2 It can be known that the adjustment device 3 includes: a first servo motor 301, the model of the first servo motor 301 is: ECMA-E11320RS, installed on the outer wall of the beam 1; a threaded rod 302, which is rotatably connected to the inner wall of the beam 1 through a bearing, and is detachably connected to the output end of the first servo motor 301; a horizontal plate 303, which is arranged on the inner wall of the beam 1 and is threadedly connected to the outer wall of the threaded rod 302; a second leg 304, which is installed at the bottom of the horizontal plate 303; when the horizontal plate 303 is forced to move along the inner wall of the beam 1, it will drive the second leg 304 to move at the same time, and a universal wheel is installed at the bottom of the second leg 304, and the universal wheel can reduce the friction between the second leg 304 and the ground when the second leg 304 moves; wherein, the first servo motor 301 can drive the threaded rod 302 to make the horizontal plate 303 move along the inner wall of the beam 1, and at the same time drive the second leg 304 to move;

[0026] In the specific implementation process, it is worth pointing out that when the horizontal plate 303 is forced to move along the inner wall of the beam 1, it will drive the second leg 304 to move at the same time. The bottom of the second leg 304 is equipped with a universal wheel, which can reduce the friction between the second leg 304 and the ground when the second leg 304 moves.

[0027] Specifically, on the basis of the above-mentioned embodiment 1, when it is necessary to adjust the width of the access control, the staff first starts the first servo motor 301 through an external power supply. After the first servo motor 301 is powered on, it starts to rotate and drives the threaded rod 302 to rotate along the inner wall of the beam 1. Because the threaded rod 302 is threadedly connected to the cross plate 303, when the threaded rod 302 rotates, it will drive the cross plate 303 to move along the outer wall of the threaded rod 302, thereby changing the distance between the beam 1 and the cross plate 303, so that the overall width of the access control structure that can adapt to different installation widths changes. When the distance between the beam 1 and the cross plate 303 can meet the use conditions, the worker turns off the first servo motor 301 and completes the width adjustment operation of the access control structure that can adapt to different installation widths.

[0028] Embodiment 3: By Figure 1 , 2 As can be seen from Figure 4, the rotating device 4 includes: two fixed plates 401, both of which are installed on the outer wall of the second support leg 304; a second servo motor 402, the model of the second servo motor 402 is: SM3L-042A1NDV, installed on the outer wall of the fixed plate 401 close to the side of the horizontal plate 303; a shell 403, which is rotatably connected to the inner walls of the two fixed plates 401 through a bearing, and is detachably connected to the output end of the second servo motor 402; the rotating device 4 is used in conjunction with the telescopic device 5 to fully open the access control, so that more pedestrians can pass through the access control, and the fixed plate 401 close to the side of the horizontal plate 303 supports the second servo motor 402; wherein, the second servo motor 402 can drive the shell 403 to rotate along the inner wall of the fixed plate 401;

[0029] In the specific implementation process, it is worth pointing out that the rotating device 4 is used in conjunction with the telescopic device 5 to fully open the access control, thereby allowing more pedestrians to pass through the access control, and the fixed plate 401 close to the side of the horizontal plate 303 plays a supporting role for the second servo motor 402;

[0030] Specifically, on the basis of the above-mentioned embodiment 1, when the telescopic device 5 needs to be rotated, the worker first turns on the second servo motor 402 through an external power supply. After the second servo motor 402 is powered on, it starts to drive the shell 403 to rotate along the inner walls of the two fixed plates 401. When the shell 403 rotates to a suitable position, the worker turns off the second servo motor 402. At this time, the shell 403 is no longer subjected to force and stops moving, thereby completing the rotation adjustment operation of the telescopic device 5.

[0031] Embodiment 4: By Figure 1 and 2 It can be seen that the telescopic device 5 includes: a door panel 501, which is arranged on the inner wall of the shell 403; a limit plate 502, which is installed on the outer wall of the first support leg 2 and is movably connected to the outer wall of the door panel 501; an electric push rod 503, the model of the electric push rod 503 is: YH-T521, which is installed on the inner wall of the shell 403 and is fixedly connected to the inner wall of the door panel 501; an access control machine 504, the model of the access control machine 504 is not specifically limited, and it can meet the use requirements and is arranged on the outer wall of the first support leg 2; the rotating device 4 is used in conjunction with the telescopic device 5. When the telescopic device 5 needs to rotate, the electric push rod 503 is first required to control the door panel 501 to break away from the limit of the limit plate 502, and then the rotating device 4 can control the telescopic device 5 to rotate; wherein, the access control machine 504 can control the electric push rod 503 to drive the door panel 501 to move along the inner wall of the limit plate 502;

[0032] In the specific implementation process, it is worth pointing out that the rotating device 4 is used in conjunction with the telescopic device 5. When the telescopic device 5 needs to rotate, the electric push rod 503 is first required to control the door panel 501 to break away from the limit of the limit plate 502, and then the rotating device 4 can control the telescopic device 5 to rotate;

[0033] Specifically, based on the above-mentioned embodiment 1, when a pedestrian walks to the access control and needs to open the access control, he first puts the access card on the access control machine 504. When the access control machine 504 detects that the access card information is correct, the access control machine 504 will control the electric push rod 503 to retract on the inner wall of the shell 403. When the electric push rod 503 retracts, it will drive the door panel 501 to move along the inner wall of the shell 403 until the door panel 501 is completely retracted to the inner wall of the shell 403. The pedestrian is no longer blocked by the door panel 501 and can pass through the access control normally. After the pedestrian passes through the access control normally, the electric push rod 503 will extend and drive the door panel 501 to move along the inner wall of the shell 403 until the door panel 501 is inserted into the inside of the limit plate 502, completing the opening and closing operations of the access control.

[0034] Embodiment 5: By Figure 1 , 2As can be seen from Figure 3, the protective device 6 includes: four transverse tubes 601, which are arranged and are all installed on the outer wall of the door panel 501; four protective plates 602, which are arranged and are all plugged into the inner walls of the four transverse tubes 601; four springs 603, which are arranged and are respectively installed inside the four transverse tubes 601 and are tightly pressed against the outer walls of the four protective plates 602; the inner wall of the transverse tube 601 is equipped with a damper, and the elastic potential energy generated by the spring 603 can be consumed through the friction between the protective plate 602 and the transverse tube 601, so that the spring 603 can be quickly stabilized; wherein, when the protective plate 602 is hit, it can move along the inner wall of the transverse tube 601 and compress the spring 603;

[0035] In the specific implementation process, it is worth pointing out that the inner wall of the cross tube 601 is installed with a damper, and the elastic potential energy generated by the spring 603 can be consumed through the friction between the protective plate 602 and the cross tube 601, so that the spring 603 can be quickly stabilized;

[0036] Specifically, based on the above-mentioned embodiment 1, when a pedestrian collides with the protective plate 602, the protective plate 602 begins to move along the inner wall of the cross tube 601 under the force, and at the same time, the compression spring 603 is used for buffering, thereby reducing the impact force on the door panel 501 and preventing the door panel 501 from being damaged due to excessive collision force. At the same time, the outer wall of the protective plate 602 is provided with a plurality of equidistant soft material balls. When a pedestrian collides with the protective plate 602, these soft material balls can reduce the impact force on the pedestrian and prevent the pedestrian from being injured.
