Energy-efficient management box for reading card and checking in

Abstract

The invention provides an energy-saving card reading and sign-in management box, which includes a device main body, an angle fine-tuning mechanism and a self-opening mechanism. The plate angle fine-tuning mechanism is assembled in the partition, and the angle fine-tuning mechanism includes a pull cord 1, a pulley 1, a blind hole 1, a magnet ring, a limit slot, a square block, a magnet block, a square plate, a chute, a blind hole 2, a nut, Threaded rod, spring 1 and sleeve, the self-opening mechanism is assembled on the left end of the box body. The self-opening mechanism includes circular groove, disc, air hole, cylinder, heat dissipation port, blind hole 3, connecting plate, pull rope 2, Pulley 2, spring 2, fixed ring 1, fixed ring 2, spring 3, limit ring, pressure bar and round hole, compared with the prior art, the present invention has the following beneficial effects: the angle adjustment of solar photovoltaic panels is achieved. purpose, and also achieved the purpose of self-opening of the heat dissipation port.

Description

technical field [0001] The invention is an energy-saving card-reading sign-in management box, which belongs to the field of electronic equipment. Background technique [0002] Electronic sign-in is based on computer technology, communication technology, identification technology and multimedia interactive technology. It is a new mobile data service product of "voucher" developed by network technology. With the development of technology, electronic sign-in equipment is widely used in meetings, training and sports training projects, especially in marathon events. Due to the large number of people and long time-consuming, the use of electronic sign-in equipment is particularly necessary. [0003] In the prior art, there are still many deficiencies in the card-reading and sign-in management box. The angle adjustment of the cover plate remains unchanged, resulting in the adjustment of the angle of the solar photovoltaic panel installed on the cover plate. At the same time, the ex...

Problems solved by technology

[0003] In the prior art, there are still many deficiencies in the card-reading and sign-in management box. The angle adjustment of the cover plate remains unchanged, resulting in the adjustment of the angle of the solar photovoltaic panel installed on the cover plate. At the same time, the existing card-reading sign-in management box The heat dissipation holes are open for a long time, and it is easy to get dust and moisture, so an energy-saving card reading and sign-in management box is urgently needed to solve the above problems
