A force control system and method for traction device

Abstract

The invention belongs to the technical field of traction equipment and particularly relates to a strength control system for a traction device. The system comprises a main working unit, an adjusting unit and a control system, wherein the main working unit comprises a first air supply part and a first exhaust part which are connected with the control system and used for supplementing and exhaustingthe air in an air bag according to needs. The adjusting unit comprises a second air supply part and a second air exhaust part which are connected with the control system, the second air supply part and the second air exhaust part provide circulating air flow for the interior of an air bag, the second air exhaust part is closed for set time when the first air exhaust part is started, and the second air supply part is closed for set time when the first air supply part is started. The system is advantaged in that the main working unit mainly controls the air pressure in the air bag, the adjusting unit assists the main working unit, the buffering effect is achieved in the pressure sudden change process, and the use comfort degree is effectively improved. The invention further provides a strength regulation and control method for the traction device.

Description

technical field [0001] The invention belongs to the technical field of traction equipment, and in particular relates to a power control system and method for a traction device. Background technique [0002] At present, with the transformation of the office model, the incidence of cervical spondylosis is getting higher and higher. Among the existing treatment methods, regular non-surgical physical therapy is the treatment method adopted by most patients. [0003] Existing cervical tractors roughly include mechanical and pneumatic tractors. Mechanical tractors can precisely control equipment such as motors that provide traction power through the control system, thereby achieving stable adjustment of traction force. However, such equipment generally The structure is more complex, the volume is larger and the price is more expensive. [0004] As a device more suitable for home use, the pneumatic retractor is favored by more people. At present, in the process of using it, the tr...

[0003] Existing cervical tractors roughly include mechanical and pneumatic tractors. Mechanical tractors can precisely control equipment such as motors that provide traction power through the control system, thereby achieving stable adjustment of traction force. However, such equipment generally The structure is more complex, the volume is larger and the price is more expensive

[0004] As a device more suitable for home use, the pneumatic retractor is favored by more people. At present, in the process of using it, the traction force is adjusted by manual pressure, that is, through the sleeve on the neck. The airbag is controlled by manual air supply, and different traction is provided through different expansion degrees of the airbag. In this way, rapid inflation and rapid deflation are easy to occur during the pressure adjustment process, and the sudden change of traction will greatly reduce the comfort of use. The change of air pressure lacks gentleness, which increases the difficulty of control and adjustment
