A construction site access control device

Abstract

The invention relates to the field of security and protection, in particular to a construction site access control device. The construction site access control device comprises a box body and in-and-out modules. The in-and-out modules are installed on the left side and the right side of the box body, a sliding rail is arranged at the bottom of the box body, and a sliding block is installed on the sliding rail; a card-swiping module is connected with a controller, the lower end of a sliding door is connected with the sliding block, and a shear-fork type mechanism is located in the box body; an air cylinder is connected with the box body through a support, a rotary shaft is connected with a blocking box through a bearing, and a reversing box is connected with the upper end of the rotary shaft; a roller is fixed to the rotary shaft and wrapped with an elastic net, the right end of the elastic net is connected with a sliding plate in a gluing mode, and the sliding plate is installed in an arc sliding groove of the blocking box; an inserting block is arranged at the right end of the sliding plate and inserted into a groove of the left end of the sliding door, and a magnet is arranged in the groove of the left end of the sliding door and can tightly attract the inserting block to enable connection of the inserting block and the groove to be more steady, so that an intercepting mechanism better plays a role; and the elastic net is made from dacron, extensibility and plasticity of the elastic net adopting the dacron are better, and the buffer effect is better.

Description

technical field [0001] The invention relates to the security field, in particular to a construction site access control device. Background technique [0002] The access control system refers to the prohibition authority of the "door", which is the guard against the "door". The "door" here, in a broad sense, includes various passages that can pass, including doors for people, doors for vehicles, etc. In the application of parking lot management, vehicle access control is an important means of vehicle management. It is not for the purpose of collecting parking fees, but mainly to manage vehicle entry and exit permissions. There are mainly two types of access control devices in the prior art, one is for long-term use, such as access control devices for office buildings, and the other is for temporary use, such as access control devices used in construction projects. Once the long-term use of access control equipment is constructed, it will not be dismantled and will be used al...
