Description

Technical Field

[0001] The utility model relates to the field of door access control devices, in particular to a door access control device capable of being opened in both directions. Background Art

[0002] Access control generally refers to the prohibition of door permissions, which is a precaution against the door. The "door" here, in a broad sense, includes various passages that can be passed, including doors for people to pass through, doors for vehicles to pass through, etc. Therefore, access control includes vehicle access control. In parking lot management applications, vehicle access control is an important means of vehicle management, so access control devices are widely used in schools, communities, factories and other facilities to prevent other vehicles or personnel from entering.

[0003] However, the current access control devices still have some shortcomings. For example, the anti-pinch function of the existing access control devices is poor, which makes it easy for people or vehicles to be pinched if they do not pass completely when the access control device is closed, thereby posing certain safety hazards to the passage of vehicles or people, and thus there are certain usage defects.

[0004] Therefore, it is urgent to improve this shortcoming. The utility model studies and improves the existing structural deficiencies and provides a door control device that can be opened in both directions. Utility Model Content

[0005] The purpose of the utility model is to provide a door control device capable of bidirectional opening, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a bidirectionally openable access control device, comprising a supporting bracket and a right-side protective door, the upper end inner surface of the supporting bracket is rotatably connected with a bidirectional driving screw, and the end of the bidirectional driving screw is equipped with a driving motor, and the left inner surface of the supporting bracket is slidably connected with the left protective door, and a storage groove is provided on the right side of the left protective door, the right protective door is slidably connected to the right inner surface of the supporting bracket, and an anti-pinch component is installed on the left side of the right protective door, and a accommodating groove is provided inside the supporting bracket, and a protective plate is symmetrically installed on the bottom inner surface of the supporting bracket.

[0007] Furthermore, the right protective door includes a door body, a viewing window, a connecting mechanism, a T-shaped slider and an auxiliary guide wheel, and a viewing window is embedded in the interior of the door body, and a connecting mechanism is fixedly installed on the left top of the door body, and the interior of the connecting mechanism is movably connected to the side of the bidirectional driving screw rod, and at the same time, a T-shaped slider is fixedly installed on the top of the connecting mechanism, and auxiliary guide wheels are symmetrically installed on the bottom of the door body.

[0008] Furthermore, the top of the connecting mechanism is fixedly connected to the bottom of the T-shaped slider, and the connecting mechanism forms a sliding structure with the supporting bracket through the T-shaped slider.

[0009] Furthermore, the anti-pinch assembly includes an elastic damping mechanism, an anti-pinch plate, a rubber protective pad, a trigger rod and a push-type emergency stop button, and the anti-pinch plate is fixedly installed on the end of the elastic damping mechanism, and the rubber protective pad is fixedly connected to the left side of the anti-pinch plate, and the trigger rod is fixedly installed on the right side of the anti-pinch plate, and a push-type emergency stop button is correspondingly arranged at the right end of the trigger rod.

[0010] Furthermore, an end of the elastic damping mechanism is fixedly connected to the right side of the anti-pinch plate, and the other end of the elastic damping mechanism is fixedly connected to the left inner surface of the door body, and the anti-pinch plate forms an elastic structure with the door body through the elastic damping mechanism.

[0011] Furthermore, the push-type emergency stop button is embedded in the left inner surface of the door body, and the installation position of the push-type emergency stop button corresponds to the installation position of the trigger rod.

[0012] Furthermore, the side of the anti-pinch component is connected to the side of the right protective door, and when the side of the right protective door is fitted and connected with the side of the left protective door, the anti-pinch component is completely immersed in the interior of the storage slot.

[0013] Furthermore, a fingerprint reader is fixedly mounted on the outer surface of the supporting bracket, and an embedded surveillance camera is embedded on the outer surface of the upper end of the supporting bracket.

[0014] The utility model provides a door control device capable of bidirectional opening, which has the following beneficial effects:

[0015] 1. The utility model provides a bidirectional driving screw rod, so that the left protective door and the right protective door can move synchronously in opposite directions when the driving motor is running, so as to achieve a bidirectional switching function, thereby effectively improving the switching efficiency of the access control device (the bidirectional switching efficiency in the same switching interval is much higher than the unidirectional switching efficiency), thereby greatly reducing the waiting time for people entering and exiting, thereby improving the convenience of using the access control device, and the setting of the auxiliary guide wheel makes the left protective door and the right protective door smoother when opening and closing, thereby greatly reducing the noise generated by the left protective door and the right protective door when opening and closing.

[0016] 2. The utility model provides an elastic damping mechanism, so that when the right protective door moves with the closing movement, if the anti-pinch plate squeezes an obstacle, it will move toward the side of the door body under the force, thereby driving the trigger rod to move toward the push-type emergency stop button. When the trigger rod presses the push-type emergency stop button, the driving motor stops running, thereby preventing the right protective door from continuing to move and causing the right and left protective doors to pinch and injure passing personnel when closing. In addition, the provision of the rubber protective pad makes it difficult for the anti-pinch plate to cause excessive harm to the pinched personnel when it comes into contact with the torso of the personnel. In addition, the provision of the storage slot makes it possible for the anti-pinch component to be perfectly moved into the interior of the left protective door when the right and left protective doors are fully closed, thereby reducing the probability of the push-type emergency stop button being accidentally touched.

By configuring the connecting mechanism 63 and the supporting bracket 1 as a sliding structure, the connecting mechanism 63 is more stable when moving left and right along the top inner surface of the supporting bracket 1, and auxiliary guide wheels 65 are symmetrically installed on the left and right of the bottom of the door body 61, a fingerprint reader 10 is fixedly installed on the outer surface of the supporting bracket 1, and an embedded surveillance camera 11 is embedded on the upper outer surface of the supporting bracket 1.

[0024] like Figure 2-Figure 4 As shown, the left inner surface of the supporting bracket 1 is slidably connected with the left protective door 4, and the right side of the left protective door 4 is provided with a storage groove 5, the right protective door 6 is slidably connected to the right inner surface of the supporting bracket 1, and the left side of the right protective door 6 is installed with an anti-pinch component 7, the anti-pinch component 7 includes an elastic damping mechanism 71, an anti-pinch plate 72, a rubber protective pad 73, a trigger rod 74 and a push-type emergency stop button 75, and the end of the elastic damping mechanism 71 is fixedly installed with the anti-pinch plate 72, the end of the elastic damping mechanism 71 is fixedly connected to the right side of the anti-pinch plate 72, and the other end of the elastic damping mechanism 71 is fixedly connected to the left inner surface of the door body 61, and the anti-pinch plate 72 forms an elastic structure with the door body 61 through the elastic damping mechanism 71, and the anti-pinch plate 72 and the door body 61 are set to an elastic structure.

Then the staff passes through the access control device. When the drive motor 3 reaches the setting When the time comes, it starts to run in reverse, so that the left protective door 4 and the right protective door 6 start to close. If the staff member has not completely passed through the access control device, as the left protective door 4 and the right protective door 6 move, the anti-pinch plate 72 fits against the staff member's body.
