As shown in fig. 1-4, this embodiment provides a multifunctional foot rest, including placing board 1, the outer lane of placing board 1 articulates through the hinge has the bracing piece 4 that three equidistance distributes, the equal fixedly connected with rubber material's in bottom of every bracing piece 4 cushion 8, and the line has all been seted up to the surface of every cushion 8, increases the frictional force between bracing piece 4 and the ground. Three draw-in grooves 2 symmetrical with bracing piece 4 respectively are seted up to the bottom surface of placing board 1, and the inside of every draw-in groove 2 all is connected with torsional spring 3, and the one end that three torsional spring 3 kept away from draw-in groove 2 respectively with three bracing piece 4 fixed connection. The side that three bracing piece 4 is close to each other has all seted up spout 5, and the equal joint in inside of every spout 5 has slider 6.

The equal fixedly connected with dog 7 of the interior roof of every spout 5 and interior diapire, and every dog 7 is the hemisphere block rubber, and every slider 6 is spherical, wearing and tearing and noise that produce when preventing that slider 6 from contacting with spout 5. The equal fixedly connected with telescopic cylinder 9 of one end that spout 5 was kept away from to every slider 6, and the inside of every telescopic cylinder 9 all is equipped with telescopic link 10. Three telescopic link 10 all is connected with the inner wall fixed connection of three telescopic tube 9 through first spring 11, and the one end that three telescopic link 10 is close to each other is connected with connecting seat 12, and the bottom of connecting seat 12 is equipped with power unit.

The power mechanism comprises a power box 14, and the front surface and the upper surface of the power box 14 are respectively provided with a treading opening 15 and a telescopic opening 16. An air cylinder 17 is fixedly connected to the inner bottom wall of the power box 14, and the air cylinder 17 is a pedal inflator and belongs to the existing equipment. The power box 14 is internally provided with an air bag 19, the bottom end of the outer surface of the air bag 19 is fixedly connected with the inner wall of the power box 14, the air bag 19 is formed by filling compressed air or water medium into a flexible rubber capsule, and the elasticity is realized by utilizing the compressibility of air and the fluidity of water. The output end of the air cylinder 17 is communicated with the input end of the air bag 19 through an air pipe 18, the output end of the air bag 19 is communicated with an air nozzle 20, the air nozzle 20 is the existing equipment commonly used on inflatable toys or tires, has good sealing performance, and finishes deflation work through the insertion of an air needle 27.

The top end of the air bag 19 is fixedly connected with a linkage rod 13, the top end of the linkage rod 13 penetrates through the telescopic opening 16 and is fixedly connected with the bottom surface of the connecting seat 12, and the outer surface of the linkage rod 13 is in contact with the inner ring of the telescopic opening 16. Inner diapire fixedly connected with dead lever 21 of headstock 14, dead lever 21 articulates through the round pin axle has sticks up pole 22, sticks up the front end fixedly connected with footboard 24 of pole 22, and the upper surface of footboard 24 has been seted up tramples groove 25, makes things convenient for trampling of user's foot. The bottom surface of the pedal 24 is fixedly connected with a second spring 23, and the bottom end of the second spring 23 is fixedly connected with the inner bottom wall of the power box 14. The rear end of the tilting rod 22 is fixedly connected with a damping block 26 made of foam board material, so that noise is prevented from being generated when the tilting rod 22 is contacted with the inner bottom wall of the power box 14. The rear end of the tilting rod 22 is connected with an air needle 27 matched with the air nozzle 20, the rear end of the air needle 27 is arc-shaped, and the tilting rod 22 performs circular motion, so that the arc-shaped air needle 27 can be inserted into the air nozzle 20.

It should be noted that the elastic extension force of the torsion spring 3 is weaker, and the friction force between the cushion block 8 and the ground is greater than the sum of the elastic extension force of the torsion spring 3 and the elastic extension force of the first spring 11, so as to prevent the automatic movement of the support rod 4.

The multi-functional foot rest of this embodiment, when the photographer needs to adjust the height of foot rest in the shooting process, the photographer's foot steps on the inflator 17, make the inside gas filling of gasbag 19 produce deformation, along with the slow increase of gasbag 19, thereby promote connecting seat 12 through gangbar 13 and carry out vertical upward movement, connecting seat 12 drives three telescopic link 10 and carries out vertical upward movement, first spring 11 carries out compression deformation this moment, pulling telescopic cylinder 9 is close to connecting seat 12, thereby make slider 6 carry out vertical upward movement in the inside of spout 5, along with the distance between telescopic link 10 and telescopic cylinder 9 is originally the less, at this moment through increasing the pulling force that continuously produces between telescopic link 10 and telescopic cylinder 9, thereby make three articulated bracing piece 4 carry out the rotation of being close to each other, thereby make the horizontal position of placing board 1 rise, reach suitable position after, stopping treading the air cylinder 17, not generating pulling force between the telescopic rod 10 and the telescopic cylinder 9, and keeping the three support rods 4 in a static state, wherein the friction force between the cushion block 8 and the ground is still larger than the sum of the elastic extension force of the torsion spring 3 and the elastic extension force of the first spring 11; when the height needs to be reduced, a photographer steps on the pedal 24 with a foot, so that the second spring 23 is compressed and deformed, the hinged warped rod 22 is rotated, at the moment, the air needle 27 is inserted into the inside of the air nozzle 20 for deflation work, because the size of the air bag 19 is reduced, the first spring 11 rebounds, the telescopic rod 10 and the telescopic cylinder 9 are far away from each other, the sliding block 6 is moved vertically downwards, at the moment, the three hinged supporting rods 4 are moved away from each other, the descending of the horizontal position of the placing plate 1 is completed, after the proper position is reached, the stepping on the pedal 24 is stopped, the second spring 23 rebounds, the air needle 27 is separated from the air nozzle 20, the deflation work is stopped, the air bag 19 stops being deformed, meanwhile, the first spring 11 is kept stable, and the friction force of the cushion block 8 is enough to stabilize the.

It should be noted that the structure of the present invention can be realized in many different forms, and is not limited to the embodiments, and any equivalent transformation, or direct or indirect application in other related technical fields, such as loading and unloading of other articles, which is performed by a person skilled in the art using the contents of the present invention and the accompanying drawings, is included in the protection scope of the present invention.
