The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1 to 6, a human body auxiliary device for welding a cabin includes two foot supporting parts 1 for supporting and fixing left and right soles of a human body, in general, a human body puts a foot step or a foot wearing shoes on the foot supporting parts 1, and fixes the shoes on the foot supporting parts 1 by a certain fixing device, for the fixing method, a common method in the present stage such as binding the shoes on the foot supporting parts 1 by using a rope, for the specific structure of the foot supporting parts 1, any device for fixing the shoes, most common structure such as a roller skate, can be used. The rear end of each foot supporting part 1 is hinged with the middle position of the U-shaped structure of the lower leg supporting part 2 through a cylindrical foot rotating shaft 11, and the hinged structure can ensure that the foot supporting part 1 swings back and forth relative to the lower leg supporting part 2, so that the feet can be bent when an electric welder moves forward. The free ends of two adjacent U-shaped structures at the inner sides of the left and right lower leg supporting parts 2 are respectively hinged with one end of two rod-shaped inner joints 5 through a cylindrical knee rotating shaft 3, and the hinging at the position can assist the electric welder to replace the movement of the knee joint when the electric welder walks. In order to enable the whole device to be matched more harmoniously when a worker walks, the other end ends of the two inner joints 5 rotate freely relative to the rod-shaped inner rotating shaft 6, and front and back alternate left and right thighs can be simulated by self rotation when the electric welder walks. The remaining two free ends of the U-shaped structure on the two lower leg supports 2 are respectively hinged with a rod-shaped outer joint 4 through a knee rotating shaft 3. In order to support the whole hip part of a worker after squatting and save strength, the outer joint 4 is provided with an arc-shaped rod-shaped bent part 41 with an upward opening in the same direction at a position far away from the knee rotating shaft 3, the free ends of the two bent parts 41 freely rotate relative to the rod-shaped outer rotating shaft 7, the arc-shaped bent part 41 can just wrap the whole hip part, and the foot part of the worker which moves forwards can not be hindered when the worker stands. Of course, in order to make the whole auxiliary device have a better effect of supporting the body of the worker, as shown in fig. 4, the shank support band 91 made of a plurality of flexible materials is connected to the shank support part 2 near the knee rotating shaft 3, the two sides of the U-shaped structure, the flexible shank support band 91 can make the worker squat and make the shank bend forward, the shank support band 91 can play a role of elastic support, thus preventing the shank of the worker from being fatigued due to the over-stressing of the muscle. In the same way, in order to better support the thigh, the outer joints 4 and the inner joints 5 on the left and right sides are connected into a whole through a thigh supporting belt 92 made of a plurality of flexible materials at a position close to the inner rotating shaft 6, as shown in fig. 4, after the worker squats, the thigh is supported to enable the worker to squat, so that the transition of the worker squat is severe, and muscle fatigue is prevented from occurring, and blood flow is not smooth. In the above structure, in order to make the whole device have a certain self-recovery property, the rear end of the foot supporting part 1, the foot rotating shaft 11, the knee rotating shaft 3, the outer joint 4 or the inner joint 5 are respectively connected in series with four elastic expansion devices 10 made of elastic materials, and one end of each elastic expansion device 10 is connected with the foot supporting part 1, and the other end is connected with the outer joint 4 or the inner joint 5. The elastic tension that whole elastic telescoping device 10 takes place when the workman stands contracts lessly, and back when the workman squats, whole device can hinder the workman to squat, according to newton's law of mechanics, when whole device hinders the workman to squat, the workman squat and receives certain hindrance, consequently can give certain support of workman after the workman squats. Greatly reducing the muscle fatigue of workers.

The working principle is as follows: first, a worker inserts the left and right legs into the lower leg support 2 as shown in fig. 4, and then the upper part of the lower leg is closely attached to the lower leg support band 91, and the muscles of the upper leg are placed on the upper leg support band 92, and the shoe and the foot support 1 are fixed together by a certain fixing device or a rope. When the worker walks, the worker can conveniently go forward due to the knee rotating shaft 3 and the inner rotating shaft 6 and the outer rotating shaft 7 in the whole device. When a long time squat is needed, the elastic expansion device 10 in the whole device cooperates with the lower leg support band 91 and the upper leg support band 92 to support and limit the squat action of people. Thereby supporting people. Because the squatting range is limited, the whole device can relieve the condition that the joint is not pressed too much, so that the damage to the joint can be greatly reduced.

In the above technical solution, the specific structure of the elastic expansion device 10 may be a specific elastic band, and the elastic expansion device 10 may also include: the first winding part B1 and the first torque spring C1 are fixed on the torsion shaft sleeve D sleeved on the foot rotating shaft 11, and the rotating directions of the first winding part B1 and the first torque spring C1 are just opposite, so that the tension of the electric welder after squatting is favorably converted into the potential energy of the torque spring to be stored together, and the larger the amplitude of squatting is, the larger the elastic extrusion force given by the whole device is, and the larger the supporting force can be given to the electric welder. A second winding part B2 and a second torsion spring C2 of circular shape are fixed on a torsion shaft sleeve D sleeved on the knee rotary shaft 3; the first fixing point A on the foot supporting part 1 is connected with one end of a first pulling wire A1, and the other end of the first pulling wire A1 is wound and fixed on a first winding part B1 clockwise; the first torque spring C1 is wound counterclockwise by the second wire a2 with the second wire winding part B2; the second torsion spring C2 is connected to a second fixed point E on the outer joint 4 or the inner joint 5 by a third pull wire A3. The advantage of this structure with torsion spring is to convert the pulling force generated after the device change into internal elastic potential energy, and the structure has longer life compared with the elastic band.

Before the device is not used, the emphasis of the body is on leaning slightly forward, typically after the worker normally squats. However, when the present invention is used, although a certain support is provided for the worker, the center of gravity of the body is deviated to the rear of the body, which is not suitable for the electric welder who needs to work and is not safe. Therefore, in order to ensure that the center of gravity of the squat body of the worker does not tilt forward after using the present invention, the thickness of the rear end of the foot supporting part 1 is made larger than that of the front end of the foot supporting part 1, and the upper surface of the foot supporting part 1 is provided with a downward inclined surface. When the height of the heel of the worker is increased, the gravity center of the person who squats down is inclined forward, and the safety is ensured. Of course, this increased height at the heel allows the ball to bear a greater compressive force. Therefore, the front end of the foot supporting part 1 is connected with a bending layer 12 made of a flexible bending-resistant material, and the bending layer 12 can reduce the elasticity of the front sole when bending. Certainly, in order to better relieve the pressure of the sole of the foot, the upper surface of the bending layer 12 is provided with a buffer layer 13 made of silica gel.

In order to prevent the hip of the worker from being worn by the outer rotating shaft 7, a hollow cylindrical support rotating shaft 8 which can freely rotate relative to the outer rotating shaft 7 is sleeved between the left outer joint 41 and the right outer joint 41 on the outer rotating shaft 7. When the buttocks of the worker contact the supporting rotating shaft 8, the buttocks of the worker are prevented from directly contacting the upper outer rotating shaft 7. The skin of the buttocks is prevented from being injured by the outer rotating shaft 7 and the free end of the bending part 41.

Of course, the most important functions of the supporting shaft 8 are: a front supporting plate 82 and a rear supporting plate 81 with an included angle smaller than 45 degrees can be fixed on the supporting rotating shaft 8. Because the front support plate 82 and the rear support plate 81 have fixed included angles, after the welder squats down, the front support plate 82 and the rear support plate 81 can firstly fall down, so that the openings of the front support plate 82 and the rear support plate 81 are always towards the ground. When the worker squats, the hip of the worker can be supported, and the stool has the function of a stool. And the rear supporting plate 81 end face is provided with an arc-shaped fillet, so that the body of a worker can be smoothly transited when the worker squats down, and the use comfort is ensured.

Generally, in a cabin, there are some places which are not all horizontal steel plates, and sometimes, it is necessary to squat on a thick circular pipe to perform welding operation, so that it is necessary to cut arc-shaped slots 83 in the bottom edges of the rear support plate 81 and the front support plate 82 as shown in fig. 8. The arc-shaped clamping groove 83 can be completely clamped on a round pipe with a thick diameter, so that the safety of workers sitting on the front supporting plate 82 and the rear supporting plate 81 in a squatting mode is guaranteed.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
