Abstract

An automate reversing traction handstand bed is a labor-saving and energy-saving fitness physiotherapy bed which causes an electric actuator and a control device organically integrate with the bed, pursuits simple and natural operation, and can automatically adjust the size and the time interval of the reversed drawing force at random, and saves labor force and saves energy. Automatic handstand can be achieved by an electric motor on the back face on the upper portion of the bed, driving gears of the electric motor, and an orbit which takes a shape of circular arc internal tooth profile on the two sides of a bed bracket. Automatic reversing suspension traction can be achieved by electric motor on the back face on the lower portion of the bed, a traction pole of the electric motor, a spring and a pipeline combination of the spring, a traction rope, a fixed puller on the lower end of the bed, and a traction shoe working together. A pocket shoulder girdle, a dorsal waist gasbag pad, a beam and a bracket of the beam that are firmly tied by the pocket shoulder pad and all controlling keys are arranged on the beam. The bed is not only applicable to the treatment of the related illness, but also can be used for individual health keeping.

Description

Automatically the anti-traction Newton bed that hangs

1 technical field

This utility model relates to the body-building physical therapy apparatus, is specifically related to a kind of counter automatically traction Newton bed that hangs.

2 background technologies

The physiotherapy traction device that uses in the ward in the past, its traction control apparatus separates with bed, and is separated by a distance, to different human body need different angles inconvenience regulated at will, ties up to adjust and be difficult to reach perfect condition, and user is mainly adjusted control by other people are auxiliary.Also have the known anti-Newton bed (patent publication No. is CN1263451A) that hangs that following deficiency is arranged: the one, counter hang pull strength can't allow user according to oneself need or ability to bear regulate control automatically; It two is to forward the preliminary stage of vertical handstand direction when bed to from horizontal direction, is not difficult to find out that according to force analysis starting torque requires big, thereby power of electric motor is required to increase, and causes utilization rate of electrical to reduce.

3 summary of the invention, 3.1 technical problems to be solved

Design this utility model be to create a kind of with electric drive and control device with bed organically combine together, make every effort to operate nature, convenience, use comfortable, the counter automatically traction Newton bed that hangs of lowering energy-saving.Allow user according to own needs, Newton bed is turned to the angle of inclination that suits realize the counter automatically traction of hanging, and the interval of the size of pull strength, traction can freely be controlled by user; The steady lifting control of Newton bed also can be finished alone like a cork by user one people, finally reaches ideal body-building physiotheraping effect.3.2 solve the problems of the technologies described above the technical scheme that is adopted

The turning cylinder of bed is set in the middle part of bed, and rotating fulcrum is due to the both sides, middle and upper part of bedrest; With realizing that bed handstand lifting drive electric motor places the top rear face of bed,, make motion on the circular arc internal tooth form track that this gear disposed in the bedrest both sides realize the automatic handstand lifting of bed by the set gear in transmission bed top rear face both sides.The back side, upper end at bed also is provided with vertical limit switch, and this switch is run into the frame rod of support and is touched when bed forwards the upright position to, allows bed vertically stop automatically with this; Soffit side at bed also is provided with horizontal limit switch, and this switch is run into the frame rod of support and is touched when bed turns back to horizontal level, allows an automatic horizontal stop with this.

To realize that the automatic anti-motor that hangs traction is arranged at the back side, bottom of bed.At the terminal spring guide that links of the draw bar of traction motor; The pairing spring of spring guide is upheld the horizontal both sides of section otch; The elastic force scale that the process metering is arranged in the telescopic notch limit standard laid down by the ministries or commissions of the Central Government; The notch of opening along spring guide is provided with and can moves and can fixed limit power switch; Be fixed in the spring guide end near the spring terminal of motor draw bar side, the other end of spring links can upholding in the middle part of the drawbar load sensing mechanism induction rod that moves with spring of horizontal positioned; The notch that the spring guide both sides are opened is passed at the two ends of this induction rod respectively, and an end is linked to drawbar load sensing mechanism, and the other end can touch the limit power switch on pogo barrel notch limit; The mid link of this induction rod is passed the external pull rope of the other end of spring guide simultaneously; Pull rope is through set fixed pulley up and down is linked to the traction sole part in the bed lower end.It is light easy that the setting of traction footwear allows user tie up just as wearing sport shoes at every turn.In the back side, bottom of bed, also be provided with the spring guide position and move totally two of limit switches, limit the range of activity of pogo barrel with this, thereby also limit the expanded range of traction motor draw bar.In addition, the control chamber that the electrical control device will be housed also is arranged on the back side of bed.

Be provided with on the top of bed sufficiently long, with the wide pocket shoulder belt of shoulder.Be provided with the solid crossbeam of pocket shoulder belt system at the middle part of bed, the flying height of crossbeam is higher than people's build thickness, and it is free to rotate that crossbeam is with an end that fulcrum is fixed on the side stand, and the other end can be fixed on the support that is provided with the crossbeam locking tip.No matter be in automatic handstand process, still counter automatically hanging in the distraction procedure, both hands can cosily be held up on crossbeam naturally very much.Be provided with realization handstand lifting starting and the button that stops about the position that armrest buttresses on the crossbeam is divided separately and realize the counter automatically button that hangs tow start, relaxes and stop; Utilize the thumb of two handss can operate this counter automatically everything that hangs the traction Newton bed of control very light, natural, easily respectively.Also be provided with the pull strength Displaying Meter at the middle part of crossbeam simultaneously so that the size of monitoring pull strength.Middle part at bed is provided with seat belt.Be provided with the back of the body waist air sac pad that can freely load and unload in the middle and upper part of bed, make human body back slightly become anti-arc by the pad tension force of air bag cushion, with this temper human body back muscle, reverse side involves vertebra, lumbar vertebra and belly muscle.

By the above, can be easily, convenient, lowering energy-saving ground realizes the counter automatically traction handstand of hanging.Use this bed accessory, not only can treat diseases such as cervical spondylosis, lumbar spondylosis, gastroptosis, nephroptosis, neurasthenia; Also can be used for loosening health, allaying tiredness, body-building brain-strengthening, thereby prophylactic generation.3.3 with existing counter hang Newton bed compare the effect that is had: 3.3.1 operation control easily, nature, convenience, tie up adjust easy.3.3.2 allow user select under the suitable angle of inclination situation, can the anti-size of pull strength and the interval of traction of hanging of regulated at will control.3.3.3 no matter be to stand upside down to start, still stand upside down and return startup, for motor, institute need starting torque require all very low, even in motor realizes standing upside down the overall process of operation, also low to the power of electric motor requirement under identical bed body rotating speed.
