Abstract
One says that edge of table pressurized ejects baffle protection device.It comprises pedal and two pieces of baffle plates; Wherein: pedal be arranged on both sides, dais trample control device, two pieces of baffle plates are the upspring type baffle plate being arranged on Liang Ge side, dais respectively, when the pin of people steps on pedal, trample control device and will automatically trigger baffle plate and automatically upspring, and reported to the police by signal light; When baffle plate lifts, there is protective effect.Described control device of trampling comprises: the induction zone be made up of piezo-resistance, electromagnetic type baffle plate device for ejecting, signal lamp and battery and switch; Wherein: the positive pole of battery is connected with the negative pole of battery with switch by piezo-resistance, magnetic-type baffle plate device for ejecting successively, and signal lamp and magnetic-type baffle plate device for ejecting are in parallel.Good and the advantage such as easy to use of edge of table pressurized ejects baffle protection device has reasonable in design that what the utility model provided say, safety.
Description
Technical field
The utility model relates to a kind of classroom apparatus, particularly relates to one and says that edge of table pressurized ejects baffle protection device.
Background technology
In the classroom of school, the front of blackboard is all provided with dais, and teacher in the class, needs to stand on dais and teaches; But say that edge of table does not have protective device, teacher is saying that edge of table says class hour, if because of carelessness, just has the danger of falling down from dais.
Summary of the invention
In order to solve the problem, the purpose of this utility model is to provide one to say, and edge of table pressurized ejects baffle protection device.
In order to achieve the above object, what the utility model provided says that edge of table pressurized ejects baffle protection device and comprises: pedal and two pieces of baffle plates; Wherein: pedal be arranged on both sides, dais trample control device, two pieces of baffle plates are the upspring type baffle plate being arranged on Liang Ge side, dais respectively, when the pin of people steps on pedal, trample control device and will automatically trigger baffle plate and automatically upspring, and reported to the police by signal light; When baffle plate lifts, there is protective effect.
Described control device of trampling comprises: the induction zone be made up of piezo-resistance, electromagnetic type baffle plate device for ejecting, signal lamp and battery and switch; Wherein: the positive pole of battery is connected with the negative pole of battery with switch by piezo-resistance, magnetic-type baffle plate device for ejecting successively, and signal lamp and magnetic-type baffle plate device for ejecting are in parallel.
Good and the advantage such as easy to use of edge of table pressurized ejects baffle protection device has reasonable in design that what the utility model provided say, safety.
Accompanying drawing explanation
What Fig. 1 provided for the utility model says that edge of table pressurized ejects baffle protection device composition schematic diagram.
What Fig. 2 provided for the utility model says that edge of table pressurized ejects the schematic diagram trampling control device in baffle protection device.
Detailed description of the invention
What provide the utility model below in conjunction with the drawings and specific embodiments says that edge of table pressurized ejects baffle protection device and is described in detail.
As shown in Figure 1, what the utility model provided says that edge of table pressurized ejects baffle protection device and comprises: pedal 1 and two pieces of baffle plates 2; Wherein: pedal 1 tramples control device for what be arranged on both sides, dais 3, two pieces of baffle plates 2 are the upspring type baffle plate being arranged on 3 two sides, dais respectively, when the pin of people steps on pedal 1, trample control device and automatically will trigger baffle plate 2 and automatically upspring, and reported to the police by signal light; Baffle plate 2 has protective effect when lifting.
As shown in Figure 2, described control device of trampling comprises: the induction zone be made up of piezo-resistance Rx, electromagnetic type baffle plate device for ejecting Ro, signal lamp L and battery E and switch S; Wherein: the positive pole of battery E is connected with the negative pole of switch S with battery E by piezo-resistance Rx, magnetic-type baffle plate device for ejecting Ro successively, and signal lamp L and magnetic-type baffle plate device for ejecting Ro is in parallel.
Edge of table pressurized ejects baffle protection device that what the utility model provided say can teacher step on say edge of table time; send light prompt signal; can also say that edge of table ejects baffle plate simultaneously; play the effect of protection, so just can effectively avoid teacher to fall down the danger at dais because of carelessness.
