Description

Technical Field

[0001] The utility model belongs to the technical field of hazardous chemicals prevention and control, and specifically relates to an access control gate. Background Art

[0002] With the rapid development of industry, many factories use hazardous chemicals to varying degrees during their production processes. There are many types of hazardous chemicals, most of which are flammable, explosive, and toxic substances. Therefore, the storage and use of hazardous chemicals require close monitoring. In existing technologies, factories lack timely monitoring of hazardous chemicals. Inspections are generally conducted manually inside warehouses, with access control gates installed at the entrances. Inspections are primarily focused on ensuring sufficient inventory of hazardous chemicals. There is a lack of record-keeping and control over the use of hazardous chemicals, and hazardous chemicals pose numerous safety risks during their use, threatening factory production safety.

[0003] A Chinese patent with announcement number CN213814812U discloses a gate machine, which includes a gate machine body with a mounting groove; and a sensing device arranged on the mounting groove; a sensing area is provided in the sensing device, and the sensing device can be rotated relative to the gate machine body to change the position of the sensing area relative to the gate machine body. By rotating the sensing device to change the position of the sensing area relative to the gate machine body, it is convenient for different people to use and the versatility of the gate machine is improved.

[0004] The turnstile in the above-mentioned comparative document controls the passage of people by a set of opposing gates. After verifying the identity of the passerby, the turnstile opens and one person passes through the turnstile at a time. During use, the turnstile with a single set of gates may fail to close in time. If other passersby want to take this opportunity to pass through the turnstile, they may be easily pinched when the gate closes.

[0005] In view of this, the present utility model is proposed. Utility Model Content

[0006] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide an access control gate.

[0007] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0008] An access control gate comprises: a gate body, verification sensors are provided on both sides of the gate body, a detachable access panel is provided on one side of the gate body, two gates are slidably engaged on one side of the gate body, telescopic plates are slidably engaged on the gates, and a switch assembly is provided between the gates and the gate body;

[0009] The switch assembly includes a rotating plate that is rotatably fitted inside the gate body and a connecting plate that is rotatably fitted on one side of the gate. The rotating plate and the connecting plate are matched with each other, and there is a certain distance between the two gates.

[0010] Optionally, an inspection cavity is provided on one side of the gate body, and an inspection plate is installed on the outside of the inspection cavity, and a fixing rod is installed in the inspection cavity, and a through groove is provided on one side of the rotating plate, which rotatably fits on the fixing rod, and a connecting column is provided on one side of the gate, and a connecting groove is provided on one side of the rotating plate, and the connecting column rotatably fits in the connecting groove, and a limit rod is provided on one side of the rotating plate, and a limit circular plate is provided on one side of the limit rod, and T-shaped limit circular grooves are provided on both sides of the connecting plate, and the limit rod and the limit circular plate slide and fit in the T-shaped limit circular groove; when the closed gate is opened, the closed gate drives the rotating plate to rotate on the fixed rod through the connecting plate, and the rotating fixed rod drives the connecting plate on the normally open gate, thereby controlling the normally open gate to move in a direction opposite to the movement direction of the closed gate, closing the entrance to the pedestrian passage, and other patrol personnel cannot enter the pedestrian passage after the normally open gate is closed, thereby reducing the occurrence of gate pinching accidents.

[0011] Optionally, two limit grooves are provided on both sides of the inner wall of the inspection chamber, and limit plates are installed on both sides of the gate. The limit plates slide in the limit grooves, and an electric telescopic rod is installed on one side of the inner wall of the inspection chamber. The telescopic end of the electric telescopic rod is equipped with a connecting rod, and one side of the connecting rod is fixedly connected to one side of one of the gates.

[0012] Optionally, a first slide groove is provided on one side of the gate, the telescopic plate slides in the first slide groove, a second slide groove is provided in the first slide groove, sliders are installed on both sides of the telescopic plate, the sliders slide in the second slide groove, and at least one spring is installed on one side of the gate and one side of the inner wall of the telescopic plate; through the coordinated use of the gate and the telescopic plate, when the gate and the telescopic plate are closed, the telescopic plate can be extended into the gate when it touches a passing passenger, thereby converting a rigid collision into an elastic collision, which can effectively avoid the problem of being pinched.

[0013] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described below at the same time:

[0014] When inspectors of hazardous chemicals warehouse use the turnstile to enter the warehouse, they authenticate their identity through the verification sensor after entering the normally open gate. After the verification is passed, the electric telescopic rod drives the closed gate to open through the connecting rod. At the same time, under the control of the switch component, the normally open gate moves in the opposite direction of the closed gate, closing the entrance to the pedestrian passage. After the pedestrian passes safely, the switch component drives the closed gate in front to close, and the normally open gate reopens. After the normally open gate is closed, other inspectors cannot enter the pedestrian passage, reducing the occurrence of gate pinching accidents, thereby improving the safety performance of the turnstile.
