Description

Technical Field

[0001] This utility model relates to the field of prison access control technology, and more specifically, to a prison AB channel door control device. Background Technology

[0002] AB doors, also known as double-door interlocking, function to prevent door B from opening when door A is open, and allow door B to open only when door A is closed; conversely, prevent door A from opening when door B is open, and allow door A to open only when door B is closed.

[0003] Currently, the control components of AB doors used in prisons or detention centers all adopt an electric sub-control structure. During operation, they are mainly operated by buttons on the control device. Existing control devices are generally installed in protective boxes for protection. However, in actual use, the control device may be subjected to external impacts. Since the control device is fixedly installed in the protective box without any buffer structure, it is easily damaged when subjected to external impacts. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a prison AB channel door control device, which has the advantage of better buffering effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a control device for a prison AB passage door, comprising a protective box, a control component movably mounted on the top of the protective box, a buffer mechanism mounted on the bottom of the control component, the buffer mechanism comprising two support rods, the two support rods being fixedly mounted at both ends of the bottom of the control component, two connecting rods being hinged to the bottom of each of the two support rods, and sliders being hinged to the bottom ends of the two connecting rods on the same support rod, the sliders being slidably mounted inside the protective box, and a buffer element being mounted at the end of the sliders.

[0006] As a preferred embodiment of this utility model, two parallel guide rails are fixedly installed at the bottom of the inner side of the protective box, and the slider can slide along the corresponding guide rails.

[0007] As a preferred embodiment of this utility model, the buffer component includes a sleeve, a rod, and a buffer spring; the sleeve is fixedly installed on the inner wall of the protective box, one end of the rod is inserted into the sleeve and can slide relative to the sleeve, the other end of the rod is fixedly connected to a corresponding slider, and the buffer spring is sleeved on the rod.

[0008] As a preferred embodiment of this utility model, the diameter of the buffer spring is smaller than the outer diameter of the sleeve and larger than the inner diameter of the sleeve.

[0009] As a preferred technical solution of this utility model, a plurality of air inlets are provided on the side wall of one end of the protective box, and the plurality of air inlets are distributed on the protective box.

[0010] As a preferred technical solution of this utility model, a heat dissipation mechanism is installed at the other end of the protective box. The heat dissipation mechanism includes a ventilation tube, which is fixedly installed on the outside of the protective box and communicates with the inside of the protective box. A fixing plate is fixedly installed on the inside of the ventilation tube, and a suction impeller is rotatably installed on the fixing plate.

[0011] As a preferred embodiment of this utility model, a first bevel gear is coaxially fixedly installed on one side of the suction impeller, a motor is fixedly installed on the outside of the ventilation cylinder, and a second bevel gear is fixedly installed on the output shaft of the motor, with the second bevel gear meshing with the first bevel gear.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. When the control component is subjected to an external impact, it will transmit the impact force to the support rod, and then to the corresponding connecting rod. This increases the angle between the two connecting rods on the same support rod, causing the two corresponding sliders to slide back and forth along the guide rail. This causes the sliders to apply pressure to the corresponding sleeve rod, which in turn causes the sleeve rod to slide into the sleeve. This compresses the buffer spring and generates elastic force. The elastic force of the buffer spring can buffer the impact force on the connecting rod, thus buffering the control component and preventing damage to the control component from large impact forces.

[0014] 2. By starting the motor, the second bevel gear rotates, which in turn causes the first bevel gear to rotate synchronously, and thus the suction impeller rotates synchronously. This reduces the pressure inside the ventilation duct, allowing air inside the protection box to be drawn into the ventilation duct and discharged outwards. At the same time, outside air can be drawn into the protection box through the air inlet. This accelerates the airflow inside the protection box, thereby improving the heat dissipation efficiency inside the protection box and also enhancing the heat dissipation efficiency of the control components.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1 to 4 As shown, this utility model provides a control device for the AB passage door of a prison, including a protective box 1. A control component 2 is movably installed on the top of the protective box 1, and a buffer mechanism 3 is installed on the bottom of the control component 2. The buffer mechanism 3 includes two support rods 31, which are respectively fixedly installed at both ends of the bottom of the control component 2. Two connecting rods 32 are hinged to the bottom of each of the two support rods 31. A slider 33 is hinged to the bottom of the two connecting rods 32 on the same support rod 31. The slider 33 is slidably installed inside the protective box 1. Two parallel guide rails 34 are fixedly installed at the bottom of the inner side of the protective box 1, and the slider 33 can slide along the corresponding guide rails 34. The two support rods 31 can support the control component 2, and the triangular structure formed between the connecting rods 32 and the slider 33 supports the corresponding support rods 31, thereby ensuring that the entire control component 2 remains stable.

[0022] The slider 33 has a buffer component 35 installed at its end. The buffer component 35 includes a sleeve 351, a rod 352, and a buffer spring 353. The sleeve 351 is fixedly installed on the inner wall of the protective box 1. One end of the rod 352 is inserted into the sleeve 351 and can slide relative to the sleeve 351. The other end of the rod 352 is fixedly connected to the corresponding slider 33. The buffer spring 353 is sleeved on the rod 352. The diameter of the buffer spring 353 is smaller than the outer diameter of the sleeve 351 and larger than the inner diameter of the sleeve 351.

[0023] When the control component 2 is impacted by an external force, it transmits the impact force to the support rod 31, and then to the corresponding connecting rod 32. This increases the angle between the two connecting rods 32 on the same support rod 31, causing the two corresponding sliders 33 to slide back and forth along the guide rail 34. This causes the sliders 33 to apply pressure to the corresponding sleeve rod 352, which in turn causes the sleeve rod 352 to slide into the sleeve 351. This compresses the buffer spring 353 and generates elastic force. The elastic force of the buffer spring 353 can buffer the impact force on the connecting rod 32, thus buffering the control component 2 and preventing it from being damaged by a large impact force.

[0024] The protective box 1 has several air inlets 5 on one side wall, and the air inlets 5 are distributed on the protective box 1. The other end of the protective box 1 is equipped with a heat dissipation mechanism 4, which includes a ventilation cylinder 41. The ventilation cylinder 41 is fixedly installed on the outside of the protective box 1 and communicates with the inside of the protective box 1. A fixing plate 42 is fixedly installed on the inside of the ventilation cylinder 41, and a suction impeller 43 is rotatably installed on the fixing plate 42. A first bevel gear 44 is coaxially fixedly installed on one side of the suction impeller 43. A motor 45 is fixedly installed on the outside of the ventilation cylinder 41. A second bevel gear 46 is fixedly installed on the output shaft of the motor 45, and the second bevel gear 46 meshes with the first bevel gear 44.

[0025] During operation, starting the motor 45 causes the second bevel gear 46 to rotate, which in turn causes the first bevel gear 44 to rotate synchronously, and thus the suction impeller 43 to rotate synchronously. This reduces the pressure inside the ventilation duct 41, allowing air inside the protection box 1 to be drawn into the ventilation duct 41 and discharged outwards. At the same time, outside air can be drawn into the protection box 1 through the air inlet 5. This accelerates the airflow inside the protection box 1, thereby improving the heat dissipation efficiency inside the protection box 1, and also improving the heat dissipation efficiency of the control component 2.
