They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0026] like Figures 1 to 4 As shown, a retractable seat for exhibitions includes a base 1 and a seat 4, a support column 2 is provided on the upper surface of the base 1, a hydraulic cylinder 3 is installed on the upper surface of the support column 2, an output end of the hydraulic cylinder 3 is installed on the lower surface of the seat 4, armrests 5 are provided on the left and right sides of the seat 4, an adjustment mechanism 6 for driving the seat 4 to rise is provided on the front of the support column 2, a supporting mechanism 7 is provided on the lower surface of the adjustment mechanism 6, a protection mechanism 8 is installed on the left side of the adjustment mechanism 6, and a control panel 9 is provided on the side of a group of armrests 5 away from the seat 4 near the protection mechanism 8; specifically, the adjustment mechanism 6 is triggered by the user's feet to push the hydraulic cylinder 3 to drive the seat 4 to move upward, so that when the user sits on the upper end of the seat 4, the legs of the user are suspended in the air without supporting themselves, so that the legs of the user can remain relaxed when using the seat for a long time to view the exhibition, thereby improving the comfort of the user when using the seat to view the exhibition, thereby improving the practicality of the device.

[0027] At the same time, by starting the support mechanism 7, the support surface of the support mechanism 7 is abutted against the ground, so that the support mechanism 7 supports the adjustment mechanism 6 during use, thereby minimizing the bending of the adjustment mechanism 6 when the user steps on the upper end of the adjustment mechanism 6, thereby increasing the service life of the adjustment mechanism 6.

[0028] like Figure 1 and Figure 2 As shown, the adjustment mechanism 6 includes a connecting block 601, a supporting plate 603 is installed on the front of the connecting block 601, a groove is opened on the upper surface of the supporting plate 603, a pressure sensor 602 is bonded inside the groove, the pressure sensor 602 is arranged at the lower end of the seat 4, the pressure sensor 602 is electrically connected to the control end of the hydraulic cylinder 3, and the control panel 9 is electrically connected to the control end of the pressure sensor 602; specifically, when the user sits on the surface of the seat 4, the user moves his legs to place his feet on the upper surface of the pressure sensor 602, so that the pressure sensor 602 triggers the hydraulic cylinder 3 to push the seat 4 upward, and when the user's feet leave the upper surface of the pressure sensor 602, the hydraulic cylinder 3 is shut down, so that the legs of different users are in a suspended state when sitting on the upper end of the seat 4, so that the legs of the users can remain relaxed when using the seat for a long time to view the exhibition, thereby improving the comfort of the users when using the seat to view the exhibition, thereby improving the practicality of the device.

[0029] At the same time, when the user descends from the upper end of the seat 4 to the ground, the pressure sensor 602 is turned off by operating the control panel 9, so that when the subsequent user relies on the support plate 603 to descend to the ground, the pressure sensor 602 cannot trigger the hydraulic cylinder 3 to push the seat 4 upward, thereby improving the safety of the user when descending from the seat to the ground.

[0030] like Figure 1 , Figure 3 and Figure 4 As shown, the support mechanism 7 includes a U-shaped fixing block 701, and through holes are provided on the inner walls of the front and rear sides of the U-shaped fixing block 701. A fixing rod 702 is rotatably connected inside the two groups of through holes of the U-shaped fixing block 701. A groove is provided on the side of the fixing rod 702 away from the U-shaped fixing block 701. An electric telescopic rod 1 703 is installed inside the groove of the fixing rod 702. A support block 705 is installed on the output end of the electric telescopic rod 1 703. An anti-slip pad 706 is bonded to the side of the support block 705 away from the electric telescopic rod 1 703.

[0031] Specifically, before the seat is used, the fixing rod 702 is rotated to rotate the fixing rod 702 away from the side of the U-shaped fixing block 701 to a position parallel to the ground, and then the support block 705 is pushed to move by starting the electric telescopic rod 703, so that the anti-skid pad 706 is abutted against the ground on the side away from the support block 705, and is installed on the lower surface of the support plate 603 through the U-shaped fixing block 701, so that the support mechanism 7 supports the support plate 603 during use, thereby avoiding bending of the connection between the support plate 603 and the connecting block 601 when the user steps on the upper end of the support plate 603, thereby preventing the adjustment mechanism 6 from being damaged during use, thereby improving the service life of the adjustment mechanism 6; the anti-skid pad 706 replaces the contact between the support block 705 and the ground, so that the support mechanism 7 is not easy to rub against the ground and make noise when the staff pushes the seat to move.

[0032] like Figure 4 As shown, a slot is provided on the upper surface of the fixing rod 702, and a magnet 704 is installed inside the slot of the fixing rod 702, and the upper surface of the magnet 704 is adsorbed on the lower surface of the support plate 603; specifically, when the staff is transporting and moving the seat, the fixing rod 702 is rotated to adsorb the upper surface of the magnet 704 on the lower surface of the support plate 603, so that the magnet 704 limits the rotation position of the fixing rod 702 inside the U-shaped fixing block 701, thereby minimizing the swinging of the fixing rod 702 back and forth when the staff is transporting and moving the seat, thereby improving the safety of the staff when transporting and moving the seat.

[0033] like Figure 1 and Figure 2 As shown, the protective mechanism 8 includes an L-shaped fixed plate 801 and an electric telescopic rod 802. A through hole is opened on one side of the support plate 603 close to the anti-slip pad 706. The electric telescopic rod 802 is installed inside the through hole of the support plate 603. The inner wall of the L-shaped fixed plate 801 is installed on the output end of the electric telescopic rod 802. The top of the inner wall of the L-shaped fixed plate 801 is attached to the upper surface of the support plate 603. Specifically, when the seat is idle, the electric telescopic rod 802 is started to push the L-shaped fixed plate 801 to move, and the top of the inner wall of the L-shaped fixed plate 801 is covered to the upper surface of the support plate 603, so that the L-shaped fixed plate 801 blocks the pressure sensor 602, thereby minimizing damage to the pressure sensor 602 during the idle storage of the seat.

[0034] like Figure 2As shown, two groups of limit blocks 10 are arranged on the side of a group of armrests 5 away from the seat 4 near the protective mechanism 8, and the positions of the two groups of limit blocks 10 are respectively arranged on the front and rear sides of the control panel 9, and the two groups of limit blocks 10 are parallel to the side of the two groups of limit blocks 10 away from the adjacent group of armrests 5 and the side of the control panel 9 away from the adjacent group of armrests 5; specifically, the two groups of limit blocks 10 are arranged on the side of the left group of armrests 5 away from the seat 4, so that the two groups of limit blocks 10 limit the moving position of the left group of armrests 5, thereby avoiding the control panel 9 on the side of the left group of armrests 5 and objects during the movement of the seat, thereby preventing the control panel 9 from being damaged during use.

[0035] In summary: the user moves his or her legs to place his or her feet on the upper surface of the pressure sensor 602, so that the pressure sensor 602 triggers the hydraulic cylinder 3 to push the seat 4 to move upward. When the user's feet are off the upper surface of the pressure sensor 602, the hydraulic cylinder 3 is shut down, so that the legs of different users are all in a suspended state when sitting on the upper end of the seat 4, so that the legs of the users can remain relaxed when using the seat to view an exhibition for a long time, thereby improving the comfort of the users when using the seat to view an exhibition; the pressure sensor 602 is shut down by operating the control panel 9, so that when the subsequent user relies on the support plate 603 to go down to the ground, the pressure sensor 602 cannot trigger the hydraulic cylinder 3 to push the seat 4 to move upward, thereby improving the safety of the users when they go down from the seat to the ground.

[0036] At the same time, by rotating the fixing rod 702, the fixing rod 702 is rotated away from the side of the U-shaped fixing block 701 to a position parallel to the ground, and then the electric telescopic rod 703 is started to push the support block 705 to move, so that the side of the anti-skid pad 706 away from the support block 705 is abutted against the ground, and is installed on the lower surface of the support plate 603 through the U-shaped fixing block 701, so that the support mechanism 7 supports the support plate 603 during use, thereby avoiding bending of the connection between the support plate 603 and the connecting block 601 when the user steps on the upper end of the support plate 603 as much as possible; by rotating the fixing rod 702, the upper surface of the magnetic block 704 is adsorbed on the lower surface of the support plate 603, so that the magnetic block 704 limits the rotation position of the fixing rod 702 inside the U-shaped fixing block 701, thereby avoiding swinging of the fixing rod 702 back and forth when the staff is moving the chair.

[0037] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and the specification only describe the principles of the utility model.
