Description

Technical Field

[0001] The utility model relates to the technical field of door access control and security equipment, in particular to an integrated door access control and security mechanism. Background Art

[0002] Access control security equipment is an important part of the entrance and exit channel control system of modern facilities. Access control equipment can restrict the people entering and exiting the entrances and exits, control and manage the normal entrances and exits inside and outside the building, and improve the security of the entire facility.

[0003] Upon investigation, it was found that the Chinese utility model patent with announcement number CN220150161U discloses an access control security device with a protective mechanism, including a main shell, the rear side of the main shell is fixedly connected with an outer fixing plate, the inner upper surface of the main shell is fixedly connected with a plurality of inner fixing plates, the upper ends of the inner fixing plates are all fixedly connected with a middle fixing plate, the upper ends of the middle fixing plates are fixedly connected with an upper fixing plate, the front upper surface of the middle fixing plate is fixedly connected with the upper fixing plate, and the rear side of the upper fixing plate is provided with a transmission mechanism and a buffer reset mechanism.

[0004] When personnel pass through the above-mentioned access control and security equipment normally, the buffer reset mechanism can assist the transmission mechanism in resetting the door panel mechanism. When the door panel is accidentally hit, the impact force from the entrance to the door panel mechanism can be absorbed and buffered by the buffer reset mechanism to prevent excessive impact force from damaging the equipment or injuring personnel. However, for personnel allowed to pass, the above-mentioned access control and security equipment can play a good buffering role. For personnel who are not allowed to pass through the access control or who pass closely following the previous person, the above-mentioned access control and security equipment does not play a blocking role. They can enter by simply pushing the door panel, thus losing the basic access control and security functions.

[0005] Therefore, the utility model provides an integrated access control and security mechanism to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0025] 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.

[0026] Example 1

[0027] The utility model provides an integrated access control security mechanism, referring to Figures 1 to 5 , including an access control box 1, a door shaft 2 rotatably arranged in the access control box 1, a door panel 21 fixedly arranged on the door shaft 2, a driving mechanism 3 arranged at one end of the door shaft 2 and a reset mechanism 5 arranged on the door shaft 2 for restoring the position of the door panel 21 and providing buffering, a limiting mechanism 4 is arranged on the door shaft 2, the limiting mechanism 4 includes a one-way gear 42 fixedly sleeved on the end of the door shaft 2 away from the door panel 21 and a limiting wheel 41 fixedly sleeved on the driving mechanism 3 for limiting the rotation of the one-way gear 42, the limiting wheel 41 includes a wheel disc 411 and a telescopic block 412 symmetrically arranged on the wheel disc 411 and having an arc-shaped end, the wheel disc 411 is provided with a receiving opening for accommodating the telescopic block 412, a spring 413 is arranged in the receiving opening, and two ends of the spring 413 are respectively fixedly connected to the inner wall of the receiving opening and the telescopic block 412.

[0028] Among them, the access control box 1 is fixedly provided with a first partition 11 located above the door panel 21 and a second partition 12 located above the first partition 11, the driving mechanism 3 includes a rotating shaft 31 rotatably connected between the first partition 11 and the second partition 12, a rotating gear a32 fixedly sleeved on the rotating shaft 31, and a motor 34 fixedly arranged on the second partition 12 and with the output end fixedly connected to the rotating shaft 31, the door shaft 2 longitudinally penetrates the first partition 11 at one end away from the door panel 21, and a driven gear a33 is fixedly sleeved on the door shaft 2 between the first partition 11 and the one-way gear 42, the rotating gear a32 is only provided with 90-degree serrations, and the rotating gear a32 is meshed with the driven gear a33.

[0029] When the access control security mechanism is working, the door panel 21 is initially in the closed position to intercept people entering and leaving. At this time, the straight surface of the telescopic block 412 in the limiting mechanism 4 conflicts with the straight surface of the sawtooth of the one-way gear 42, so that the one-way gear 42 cannot rotate in the direction of opening the door panel 21. After recognizing the person's pass, the motor 34 drives the rotating shaft 31 to rotate, the rotating shaft 31 drives the rotating gear a32 to rotate, and the rotating gear a32 drives the driven gear a33 to rotate ninety degrees and then no longer meshes. The driven gear a33 drives the door shaft 2 and the door panel 21 to rotate ninety degrees to open the passage. When people pass through, the driven gear a33 is no longer affected by the rotating gear a32. At this time, the door shaft 2 is only slowly closed by the reset mechanism 5. People who pass by accidentally fall or otherwise hit the door panel 2 1, the reset mechanism 5 can provide a certain buffer. At this time, the motor 34 continues to rotate. When a person passes through, the motor 34 rotates from ninety degrees to half a circle. At this time, the telescopic block 412 contacts the one-way gear 42 again. During the closing process of the door panel 21, the one-way gear 42 contacts the arc-shaped side of the telescopic block 412, squeezing the telescopic block 412. The telescopic block 412 squeezes the spring 413 and retracts into the wheel 411, which does not affect the closing of the door panel 21 under the action of the reset mechanism 5. However, when someone continues to pass through when the previous person passes and the door panel 21 is not completely closed, the telescopic block 412 will jam the one-way gear 42 to prevent the door panel 21 from opening again, making it impossible for the following person to enter through the narrow space. When the door panel 21 is completely closed, the motor 34 rotates half a circle again to return to the initial state.

[0030] Example 2

[0031] Different from Example 1, the reset mechanism 5 includes a fixed gear 51 rotatably connected to the bottom of the second partition 12, a fixed shaft 52 with one end fixedly connected to the bottom of the fixed gear 51, a torsion spring 53 sleeved on the fixed shaft 52 for resetting the door shaft 2, a rotating gear b54 fixedly sleeved on the rotating shaft 31, and a transition gear 55 rotatably connected to the bottom of the second partition 12 and meshing with the rotating gear b54 and the fixed gear 51 at the same time, the rotating gear b54 is only provided with ninety-degree serrations, and the rotation angle of the fixed gear 51 is ninety degrees.

[0032] It is worth noting that one end of the fixed shaft 52 away from the fixed gear 51 is rotatably connected to the one-way gear 42 , and two ends of the torsion spring 53 are respectively fixedly disposed on the fixed gear 51 and the one-way gear 42 .

[0033] When the motor 34 drives the rotating shaft 31 to rotate ninety degrees, the rotating gear b54 starts to mesh with the transition gear 55 for transmission. When the motor 34 rotates ninety degrees again, the rotating shaft 31 drives the door shaft 2 and the transition gear 55 to rotate in opposite directions. The transition gear 55 drives the fixed gear 51 to rotate in the same direction as the rotating shaft 31, so that the fixed gear 51 rotates in the opposite direction to the door shaft 2, increasing the torque of the torsion spring 53. When a person holding a pass passes through, the closing of the door panel 21 is accelerated, which can effectively prevent the following person from taking the opportunity to pass through. After the door panel 21 is closed, the motor 34 rotates half a circle again, and the fixed gear 51 and the transition gear 55 return to the initial state under the action of the torsion spring 53.

[0034] Furthermore, the access control box 1 is provided with a sensing device 13 for sensing the passage of a person and transmitting an alarm device on one side close to the door panel 21. The sensing device 13 is located above the door panel 21. The sensing device 13 can sense the walking position of a person holding a pass, thereby controlling the operation of the motor 34 according to the position of the person. When the door panel 21 is not opened, when the passage of a person is sensed, the alarm device can be connected to remind the guard.

[0035] Furthermore, a limiting plate 14 is fixedly provided on the access control box 1 to prevent the door panel 21 from rotating in the reverse direction, thereby preventing the door panel 21 from being rotated in the reverse direction and passing through.

[0036] It is worth noting that door pads 22 for cushioning impact are fixedly provided on the inner and outer surfaces of the door panel 21 , so as to reduce the damage to a person when colliding with the door panel 21 .

[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
