Special barrier used in examination room

Abstract

A special barrier used in an examination room comprises barrier pillars, a portal frame, a metal detector and signal jammers, wherein channel steel rails and hydraulic lifting devices are arranged in the barrier pillars; the channel steel rails are mounted on the inner walls of the barrier pillars; each hydraulic lifting device comprises rail wheels, a hydraulic rod, an oil-pressure jack, a chain, a rotating wheel and a lifting rod; the rail wheels are mounted in the channel steel rails; the lifting rods are connected with the middle shafts of the rail wheels; the rotating wheels are mounted at the oil-pressure jack heads of the oil-pressure jacks; one end of each of the chains is fixed at the bottoms of the barrier pillars; the other end of each of the chains bypasses the rotating wheels to be connected with the lifting wheels; the portal frame is fixed to the lifting rods; the metal detector is fixed on the portal frame; the signal jammers are fixed on the barrier pillars. The special barrier used in the examination room integrates the functions of metal detection, signal jamming and examination room information display and has the characteristics of high practicability and suitability for being popularized in a large range.

Description

technical field [0001] The invention belongs to the field of examination invigilation equipment, and in particular relates to a special barrier for an examination room which is placed at the entrance of an examination room and is capable of metal detection, signal interference and information display of the examination room. Background technique [0002] With the vigorous development of my country's education, the number of examinations has also increased. Although integrity examinations are now advocated, metal detection is still required before the examination to prevent candidates from carrying prohibited items, and signal interference is always carried out during the examination to prevent candidates from carrying prohibited items. Cheating by means of communication. [0003] Before the test starts, it is usually necessary to post the test room and test information at the entrance of the test room, and it needs to be torn off after the test, which wastes resources.

AI Technical Summary

Problems solved by technology

[0003] Before the test, it is usually necessary to post the test room and test information at the entrance of the test room, and it needs to be torn off after the test, wasting resources

Before the start of the test, the invigilator needs to hold a metal detector to check the candidates one by one, which wastes a lot of time; and the signal jammer is usually a certain distance from the test room, and the signal interference cannot achieve satisfactory results
