Description

Novel light-resistant projection curtain structure for classroom

Technical Field

The utility model relates to the technical field of teaching equipment, in particular to a novel light-resistant projection screen structure for a classroom.

Background

At present, the mode of assisting classroom teaching by using a multimedia technology is increasingly adopted by most schools, and a good teaching effect is obtained. One of the technologies of multimedia technology teaching is to project animation or pictures on the wall or other positions in front of the classroom by using a projection mode to improve the interestingness in the teaching process and stimulate the interest and fun of students in learning, thereby improving the efficiency of the students in learning professional knowledge. Such multimedia technology generally requires a projection screen to form a projection surface when necessary to display contents projected by a projector, and a conventional projection screen is generally hung on a wall in the front of a classroom, and in a non-use state, the projection screen is generally rolled up on a rotating shaft and pulled down to form the projection surface when in use.

However, although the conventional projection curtain can basically realize the basic functions of multimedia teaching, the conventional projection curtain also has the obvious disadvantage that after the projection curtain is unfolded, one end part of the curtain is a resource end and is easily interfered by external factors such as weak wind power and the like, and the curtain is easy to shake to influence the projection effect of the curtain.

SUMMERY OF THE UTILITY MODEL

Aiming at the defects in the prior art, the utility model provides a novel light-resistant projection curtain structure for classrooms, and solves the problem that the existing projection curtain is easily influenced by external force to shake, so that projection deformation is not clear.

In order to solve the problems, the technical scheme adopted by the utility model is as follows: the utility model provides a novel classroom is with projection curtain structure of anti light, includes curtain, motor, pivot, support, controller and sensor, and pivot one end is connected with the leg joint, and pivot other end fixedly connected with first gear, motor and support fixed connection, motor output shaft one end fixedly connected with and first gear engagement's second gear, motor, sensor are connected with the controller electricity respectively, the curtain lower extreme can be dismantled and be connected with the gravity pole, and the gravity pole is close to blackboard one side and is equipped with the sucking disc.

The beneficial effect that this scheme produced is: 1. the sensor receives signals and transmits the signals to the controller, and the controller controls the motor to start, so that the curtain is automatically unfolded in a remote mechanical and electric control manner, and the curtain is convenient and practical; 2. the sucking disc through the gravity pole setting can adsorb the curtain lower extreme on the blackboard to fixed curtain reduces to rock because of the curtain and causes the fuzzy deformation scheduling problem appearance of projection picture, improves the teaching result of use, and this scheme simple structure, low cost easily reequips.

Furthermore, the rotating drum is sleeved on the spline of the rotating shaft, and one end of the curtain is fixedly connected to the rotating drum. Because of rotary drum and pivot splined connection, the rotary drum can slide relative to the pivot to can follow the horizontal direction adjustment curtain position, convenient to use.

Further, the one end that the motor was kept away from to the rotary drum rotates and is connected with the lantern ring, lantern ring upper end support fixedly connected with telescopic link, and the telescopic link is connected with the controller electricity through the connecting rod and the lantern ring fixed connection that set up along vertical direction, telescopic link. Through design telescopic link electric control curtain horizontal adjustment, need not artifical manual the going on, convenient to use is swift.

Furthermore, the lower extreme sliding connection of gravity pole has the slide bar, still includes the gag lever post, and the gag lever post is opened has the spout that can supply the slide bar embedding, and the lower extreme at the blackboard can be dismantled to the gag lever post and connect. Through setting up slide bar and gag lever post, can carry on spacingly with slide bar embedding gag lever post after the curtain expandes to make the curtain relatively fixed, reduce the curtain and rock, improve projection picture quality, thereby promote the teaching effect.

Further, the support upper end can be dismantled and be connected with the shield that sets up along the horizontal direction, and the shield lower extreme can be dismantled and be connected with the baffle, and the baffle sets up along vertical direction. The dust cover is used for preventing dust from falling into the curtain structure to influence the use of the curtain; through setting up the baffle and reducing external force and destroy the curtain structure, protect improve equipment life to mechanical structure.

Furthermore, the lower end of the baffle plate is detachably connected with a hairbrush, and the hairbrush head is in contact with the surface of the unfolded curtain. Because there is more chalk dust in classroom podium part, be infected with on the curtain easily, influence curtain projection definition, the brush can be clear away curtain surface dust when the curtain expands or contracts.

Further, the curtain adopts black grid structure light-resistant projection curtain, and black grid structure light-resistant projection curtain has great visual angle, can be close to 180 degrees, is fit for many people multi-angle to see the shadow, and positive light resistance is better and no reflection of light, and its size is optional, soft or hard all can, convenient customization, and the gain is generally at 0.6 ~ 0.9.
