Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0024] Please refer to Figures 1-3 , Figure 1 A front structure schematic view of one embodiment of the anti-gravity chair provided by the present application; Figure 2 A side structure schematic view of one embodiment of the anti-gravity chair provided by the present application; Figure 3 A whole structure schematic view of one embodiment of the anti-gravity chair provided by the present application.

[0025] In one specific embodiment, the anti-gravity chair comprises a support column 10, a seat body 20, a fixed pulley set 30 and a movable pulley set 40. The seat body 20 is connected with a fixed shaft of the movable pulley set 40. A fixed shaft of the fixed pulley set 30 is connected with the support column 10. A fixed pulley of the fixed pulley set 30 and a movable pulley of the movable pulley set 40 are transmissionally connected through a tension rope 50. A user in the seat body 20 can realize the height change of the seat body 20 by pulling the tension rope 50. A fall protector 60 is arranged between the top of the support column 10 and the seat body 20, for preventing the seat body 20 from falling to the ground.

[0026] The fixed pulley set 30 is installed on the support column 10, and the movable pulley set 40 is installed on the seat body 20. The two are transmissionally connected through the tension rope 50. The user can realize the height change of the seat body 20 by pulling the tension rope 50, and the effect of anti-gravity is realized. The fall protector 60 is arranged to prevent the seat body 20 from falling to the ground quickly, and the use safety is improved. The fixed pulley set 30 and the movable pulley set 40 are applied, the effect of saving labor is realized, the working strength of the operator is reduced when the chair is used as an outdoor equipment, compared with the cylinder structure, there is no complex hydraulic or pneumatic system, the overall structure is simple, the failure points caused by the complex components are reduced, the failure probability is reduced, the pulley set can better adapt to the harsh outdoor environment, the maintenance is relatively simple, the maintenance difficulty and cost are reduced, the user can experience in real time while facing the structure of the pulley set, the learning effect is improved, and the use safety is improved by arranging the fall protector 60.

[0027] Due to the actual rising or falling process, the seat body 20 may be shaken laterally relative to the support column 10 due to stress and other reasons, which is not conducive to the user's up and down control of the seat body 20, reduces the experience of use, and on the other hand, frequent shaking may cause relative connection at the connection, causing damage to the support column 10 and other parts, and easily causing safety accidents.

[0028] To solve the above technical problems, in one embodiment, the anti-gravity chair further comprises a buffer wheel set 21 arranged between the side of the support column 10 and the seat body 20, and the buffer wheel set 21 is welded or bolted to the side of the support column 10 and the seat body 20.

[0029] By arranging the buffer wheel set 21 between the side of the support column 10 and the seat body 20, as long as there is horizontal displacement during the up and down movement of the seat body 20, the buffer wheel set 21 will be buffered, reducing the kinetic energy of horizontal shaking and reducing the difficulty of use.

[0030] The size, number, material and specific installation method of the buffer wheel set 21 in the present application are not limited.

[0031] The buffer wheel set 21 in the present application can be installed on the support column 10 or the seat body 20. In order to avoid horizontal shaking, the rotation of the buffer wheel set 21 cannot be in the horizontal plane. Otherwise, if the seat body 20 moves in the horizontal circumferential direction, the buffer wheel set 21 will hardly cause resistance, and the buffer wheel rotating in the vertical direction will not rotate in the circumferential direction, which can slow down well, and in the up and down direction, it will not increase the pulling resistance, improving the reliability of use.

[0032] The buffer wheel set 21 in the present application includes but is not limited to rubber wheel set, and can also use silica gel wheel or other flexible materials.

[0033] In the present application, the user needs to manually pull the rope to realize anti-gravity operation. Different people may adapt to different heights. In one embodiment, the support column 10 is a telescopic support column 10, and the telescopic support column 10 adjusts the height difference between the fixed shaft of the fixed pulley set 30 and the ground through telescoping.

[0034] By using the telescopic support column 10, the height difference between the fixed shaft of the fixed pulley set 30 and the ground is adjusted through telescoping, so that it can meet the height lifting needs of different personnel.

[0035] The telescopic structure of the telescopic support column 10 is not limited in the present application, and can be controlled in height by a cylinder structure, a gear structure, or other structures.

[0036] In order to further improve the comfort of use, in an embodiment, the anti-gravity chair further comprises a cushion layer arranged at the bottom of the seat body 20, for buffering during the falling of the seat body 20.

[0037] By arranging the cushion layer at the bottom of the seat body 20, the falling of the seat body 20 is buffered, so that even if it collides with the ground, no safety accidents will occur, and the comfort and safety of use are improved.

[0038] The material, installation method, and size of the cushion layer are not limited in the present application.

[0039] In addition to the rubber pad structure, the cushion layer can also adopt an inflatable structure, which can be automatically inflated when the falling speed reaches a certain speed, ensuring the reliability of use.

[0040] In order to further improve the safety of use, in an embodiment, the anti-gravity chair further comprises a limiting groove arranged on the side of the support column 10 facing the seat body 20, for limiting the buffer wheel set 21 on the support column 10.

[0041] By arranging the limiting groove on the side of the support column 10 facing the seat body 20, the buffer wheel set 21 is limited on the support column 10, so that the lateral distance between the support column 10 and the seat body 20 is fixed during the whole movement, improving the safety and reliability of use.

[0042] The structure of the limiting groove is not limited in the present application, and the limiting groove can be machined on the support column 10 or installed separately.

[0043] The size, number, and forming method of the limiting groove are not limited in the present application.

[0044] The fall arrestor 60 is used to prevent the seat body 20 from falling to the ground in the present application, and the structure, model, and connection method are not limited.

[0045] In the application, the seat body 20 needs to be connected with other components, and during the connection process, if the force is connected on the side of the seat body 20, the seat body 20 may be tilted, which reduces the comfort and reliability of use. In order to improve the use efficiency and reliability, and improve the installation efficiency, in an embodiment, the anti-gravity seat further comprises an upwardly extending curved extension provided on the back of the seat body 20, the center of curvature of the curved surface of the curved extension is located on one side of the seat body 20, and at least one mounting position is provided on the side of the curved extension away from the seat body 20. The fixed shaft of the movable pulley and the lower end of the fall arrestor 60 are connected with the seat body 20 through the mounting position.

[0046] By providing an upwardly extending curved extension on the back of the seat body 20, the space of the seat body 20 is not blocked during the connection process of the seat body 20, which does not reduce the comfort of use. At the same time, by connecting at the mounting position of the curved extension, the force during the connection process can be as vertical as possible, which does not cause the seat body 20 to be deflected, improves the safety and reliability of use, and reduces the possibility of the seat body 20 being rotated, thereby improving the stability of the equipment.

[0047] In the application, the size, material and mounting position of the curved extension are not limited, and the formation method of the curved extension is not limited, which can be by installing an independent component to the seat body 20, or by integrally processing the seat body 20.

[0048] In the application, there is a gap between the seat body 20 and the support column 10, and the connection needs to be made at the top of the support column 10, so the installation space is small, and it is not convenient to install the fixed pulley block 30, and the force direction is difficult to be vertical. In order to improve the installation efficiency and convenience, in an embodiment, the anti-gravity seat further comprises a transverse extension 90 provided on the top of the support column 10, the fixed shaft of the fixed pulley block 30 is installed on the transverse extension 90, a rotating wheel and a speed reduction fan 80 are provided on the top of the transverse extension 90, the output end of the tension rope 50 is connected with the movable pulley of the movable pulley block 40 through the rotating wheel, the speed reduction fan 80 is coaxially connected with the rotating wheel, the rotating wheel is provided with a ratchet wheel, which drives the speed reduction fan 80 to rotate during the descent of the seat body 20, and the speed reduction operation is performed on the seat body 20.

[0049] The transverse extension 90 provides space for connecting the seat body 20, and the staff can adjust the installation position of the top of the seat body 20 according to the size of the seat body 20, and other components can also be provided to improve the installation efficiency and convenience.

[0050] The size, structure, and installation method of the transverse extension 90 are not limited in the present application, and the transverse extension 90 can have some installation positions and have an installation position adjustment function.

[0051] To further improve the learning effect of the user on the pulley, in an embodiment, the anti-gravity chair further comprises a parameter sign provided on the seat body 20, which is used to identify the fixed pulley parameter in the fixed pulley set 30, the movable pulley parameter in the movable pulley set 40, the weight parameter of the seat body 20, and the mechanical efficiency of the fixed pulley set 30 and the movable pulley set.

[0052] By setting the parameter sign to display the relevant pulley parameters, the user can quickly obtain the overall device information, and can compare the calculated values with the actual pulling force to improve the learning efficiency of the pulley principle.

[0053] The size, structure, material, and marking method of the parameter sign are not limited in the present application, and in addition to the above, the structure diagram of the entire device or other parameters can also be identified.

[0054] Further, to improve the test accuracy, in an embodiment, the anti-gravity chair further comprises a display and a communication module provided on the seat body 20, the display is used to display the fixed pulley parameter, the movable pulley parameter, the weight parameter, and the pulling force value and length change value of the pulling rope 50, and the communication module is used to output the display content of the display.

[0055] By setting the display, the device parameters can be displayed in real time, corresponding to the parameter sign, and the data of the sensor can also be displayed, and even a processor can be provided for related efficiency calculation, to improve the learning efficiency.

[0056] The communication module is provided, and the user can output the relevant data information to the user through the communication module, so that the user can obtain the information in real time.

[0057] In addition, the application can also achieve different transmission ratios by changing the connection relationship of the fixed pulley set 30, the movable pulley set 40, etc. For example, one of the fixed pulley connecting shafts can be transferred from the support column 10 to the seat body 20, the movable pulley can be transferred from the seat body 20 to the support column 10 to become a fixed pulley, or a reserve fixed pulley or movable pulley can be added, etc. The overall pulley structure is changed, and the device information is processed by the processor in the display.

[0058] In one embodiment, the anti-gravity seat, as shown in Figure 1 The rubber wheel set is arranged in an upper and lower arrangement, is installed around the support column 10, and is welded on the seat body 20. This can prevent the seat body 20 from swinging and can also serve as a buffer when descending.

[0059] The fixed pulley reinforcing steel plate 31 is arranged in the fixed pulley set 30 to strengthen the structure and prevent external dust from entering the fixed pulley set 30, thereby protecting the fixed pulley set 30.

[0060] When a person sits on the seat body 20 and pulls the tension rope 50 with his hand, the tension rope 50 passes through the rotating wheel and reaches the movable pulley. The tension rope 50 forms multiple strands of rope between the movable pulley and the fixed pulley. This can bear the weight of the human body and save the operating strength of the person. When descending, the tension rope 50 is loosened, and the whole body will automatically slow down.

[0061] When the tension rope 50 passes through the rotating wheel, it will also drive the rotation of the deceleration fan leaf. The existence of the deceleration fan leaf is to rotate the fan leaf when the human body descends, thereby increasing the resistance.

[0062] The fall arrestor 60 is connected to the chair through the rope and plays a role in ensuring safety.

[0063] The transverse extension part 90 is composed of a horizontal steel plate 91 and a vertical steel plate 92, which are welded together and structurally reinforced by a reinforcing rib 93. The rotating wheel reinforcing steel plate 71 is arranged in the rotating wheel 70 to improve the structural strength thereof. The seat body 10 includes a first support pipe 11 and a second support pipe 12, which are connected by a connecting steel plate 111.
