The invention aims to provide a shading device for psychological experiments, which solves the problem that the shading device for psychological experiments in the prior art is inconvenient for a testee to control.
In order to achieve the aim, the basic scheme of the invention provides a shading device for psychological experiments, which comprises a base, wherein a vertical guide frame is fixedly connected to the base, and a transverse supporting plate is connected to the guide frame in a sliding manner along the vertical direction; two supporting frames are arranged on the base, and shading cloth is connected to the supporting frames; the pneumatic type telescopic mechanism comprises a base, and is characterized in that a sliding block is connected to the base along the vertical sliding direction, a supporting frame is hinged to the sliding block, a shifting rod is fixedly connected to the supporting frame, the shifting rod is fixedly connected with one end, close to the sliding block, of the supporting frame, the end, far away from the supporting frame, of the shifting rod is located on the lower side of a supporting plate and is in sliding fit with the supporting plate, a pneumatic type telescopic mechanism for pushing the sliding block to slide is arranged on the base, a pedal is connected to the base along the vertical sliding direction, is located below the supporting plate, an air pump for inflating by oneself is arranged on.
The principle and the beneficial effect of the basic scheme are as follows: the guide frame and the supporting plate are arranged, so that a testee can sit on the supporting plate conveniently, and the supporting plate is driven to move downwards. A supporting frame is arranged for supporting the shading cloth. And arranging a sliding block for changing the position of the bottom of the supporting frame. And the shifting rod is used for driving the supporting frame to rotate. A pedal is provided for driving the air pump to draw air. And a pneumatic telescopic mechanism is arranged for driving the sliding block to move.
Initially, the two frames are separated, and when the subject stands on the pedal, the pedal drives the air pump to work to suck air, so that a large amount of air is stored in the air pump. Then, the tested person slowly sits on the supporting plate, at the moment, the center of gravity of the person is gradually transferred to the supporting plate from the upper part of the pedal, so that the pressure on the pedal is reduced, the air pump on the lower side of the pedal automatically fills air into the pneumatic telescopic mechanism, the pneumatic telescopic mechanism pushes the sliding block to move, one end of the deflector rod, far away from the sliding block, abuts against the supporting plate, and then when the sliding block moves, the supporting frame rotates upwards; with the downward movement of the supporting plates, the shifting rod continues to swing around the sliding block, so that the supporting frames continue to rotate upwards until the two supporting frames drive the shading cloth to abut against each other, and the supporting frames drive the shading cloth to cover a testee, thereby forming a shading effect. When the testee feels any discomfort and wants to terminate the experiment, as long as the testee stands up, the deflector rod loses the pressing effect of the supporting plate, so the supporting frame is separated towards two sides under the action of gravity, the testee can see the surrounding environment immediately, and further the discomfort reaction is avoided from continuing to occur.
The driving support frame drives the shading cloth to move by utilizing the self gravity of the testee, and an additional power mechanism is not required to be introduced, so that the use cost is reduced. Through the difference of the barycenter position that utilizes the tester state of standing and the state of sitting to reach the effect of driving the driving lever behind the air pump of forerunner, the production of this effect is just that the tester is from standing to sitting this in-process in the same direction as taking the production, need not to set up operating procedure deliberately and makes the tester control, thereby has improved the use convenience of this device, makes things convenient for the tester to control. Through the change of the state of the testee from standing to sitting down, make the backup pad when just contacting the human body, at this moment, pneumatic type telescopic machanism just begins to work, the slider just begins to remove, the driving lever is great to the holding power of backup pad, along with the removal of slider, the skew takes place for the focus of carriage, the driving lever reduces to the holding power of backup pad gradually, thereby make the testee from contacting the backup pad and the in-process of sitting down gradually, the holding power of backup pad reduces gradually, make the testee have a transient adaptation process, just take place the uncomfortable sensation of heeling backward because of the holding power of backup pad is less when having avoided the testee to contact the backup pad, thereby the comfort of testee has been improved.
Furthermore, rigid rods are arranged at the crossed positions of the shading cloths on the two supporting frames. Through setting up the rigidity pole, make things convenient for better corresponding laminating when two shading cloth intersect.
Further, a sponge cushion is fixedly connected to the rigid rod. Through setting up the foam-rubber cushion, can come to seal the gap between the rigidity pole through the deformation of foam-rubber cushion, avoid external light to get into.
Further, an arc-shaped sliding rail is fixedly connected to the base, and the sliding block is connected with the sliding rail in a sliding mode. Set up curved slide rail, make the movement track of slider be the arc, then, the slider all has the displacement in horizontal and vertical two directions, can form the extension effect to the shading cloth in horizontal.
Furthermore, the axis of the deflector rod is positioned below the radius of the sliding block on the sliding rail. Therefore, the direction of the force applied to the sliding block by the supporting plate through the shifting rod is approximately the same as the direction of the force applied to the sliding block by the pneumatic telescopic mechanism, and the effect of mutually offsetting acting forces caused by the force in the opposite direction is avoided.
Furthermore, the pneumatic type telescopic mechanism is located between the two sliding blocks, and two ends of the pneumatic type telescopic mechanism are respectively hinged with the corresponding sliding blocks. The two sliding blocks can be pushed to move through one action of the pneumatic telescopic mechanism, and the operation is convenient.
Further, the pneumatic telescopic mechanism is connected with the base in a sliding mode along the vertical direction. The pneumatic telescopic mechanism and the sliding block can move vertically together, so that the telescopic direction of the pneumatic telescopic mechanism is relatively fixed.
Further, the pneumatic telescopic mechanism is a bidirectional telescopic cylinder. The two ends of the bidirectional telescopic cylinder can be simultaneously telescopic, and the middle position can be kept unchanged, so that the bidirectional telescopic cylinder is convenient to install and use.
Furthermore, the slide block is rotatably connected with a roller, and the roller is in contact fit with the slide rail. The abrasion between the sliding block and the sliding rail can be reduced through the roller.
Furthermore, the deflector rod is an elastic telescopic rod. The length of the shift lever can be adaptively adjusted, so that interference among the shift levers is avoided; simultaneously, the driving lever can extend by oneself under the effect of losing pressure to make the backup pad rise fast under the effect of gravity that loses the person under test, and then make the carriage separation that can be more quick.
