Description

A kind of self-service extension table of ratchet control

Technical field

This utility model relates to the equipment of a kind of casual health and medical treatment, especially, relates to the self-service extension table of the ratchet control of a kind of simple and easy, detachable, portable treatment or prevention lumbar vertebra and cervical spondylosis.

Background technology

Waist, neck degenerative osteoarthritis and prolapse of lumbar intervertebral disc are the major reasons that causes waist, cervicodynia, and waist, cervicodynia are modal diseases in the orthopaedics illness.According to statistics, China has more than 1,000 ten thousand people to suffer from the outstanding disease of lumbar disc.Particularly along with the popularizing of computer, people's office and amusement more and more depend on computer, and the life-time service computer causes waist, cervical region to be ached easily, and then causes cervical spondylosis.In the method for treatment waist, NC, traction treatment is simple, safe, painless with it, effectively be widely used.Traction treatment not only can make outthrust also receive, and also helps little joint disorders correction and resets, and make intervertebral foramina recover normal appearance, thereby remove the extruding to nerve root; Draw can make disruptive disc tissue evacuate distortion or migration, and nerve root obtains decompression and obtains treatment; Can make soft tissue release, remove muscle spasm, eliminate the extruding of body weight, improve circulation, and the pathogenic goods and materials of exopathogenic factor are reduced, thereby reach the analgesic purpose intervertebral disc.

Late nineteen seventies, extension table just enter clinical use.But in the extension table that uses, external extension table complex structure is operated inconvenience, and is costly at present; Domestic extension table is then relatively heavier, bulky, not easy to assemble, also will occupy certain space obsolete the time.And existing extension table generally can only use in hospital.

Along with the goods and materials growth in the living standard, people more and more pay attention to healthy, wish to reach prophylactic purpose by certain physical therapy, still, also do not prevent the detachable self-service extension table of simple type of waist NC at present in the society.

The utility model content

The purpose of this utility model is the deficiency at above-mentioned existing extension table, the self-service extension table that provides a kind of ratchet simple in structure, that be easy to dismantle to control.

The purpose of this utility model is achieved through the following technical solutions: a kind of extension table for the treatment of lumbar vertebra and cervical vertebra, mainly form by stand arrangement, power set and traction apparatus; It is characterized in that, described stand arrangement mainly by bedstead, be connected bed shelves on the bedstead, first bed board on the bed board carriage and second bed board on the bed shelves and form; Described bed shelves are socketed to form the detachably also scalable adjustment of member each other by the section bar of two kinds of different sizes; Described power set mainly by the loading rope that is fixed on the pulley on the bedstead, the coupling spindle that an end is fixed in pulley center, the ratchet that is fixed in the coupling spindle other end, fork, connection fork, be connected driving ratchet that fork flexibly connects, be connected on extension spring on the fork, the braking ratchet, near the making leaf spring of braking ratchet be connected the unloading rope of braking ratchet and form; By pull rope, the draw bar that links to each other with pull rope, the traction belt that links to each other with draw bar is formed in the described traction apparatus.

The utlity model has following technique effect: simple in structure, easy to operate, be easy to the dismounting, be easy to carry, be suitable for using in places such as hospital, community and families.

Description of drawings

Fig. 1 is the structural representation of extension table of the present utility model.

The specific embodiment

Describe specific embodiment of the utility model below with reference to the accompanying drawings in detail.

Embodiment

As shown in Figure 1, extension table of the present utility model mainly is made up of stand arrangement, power set and traction apparatus.Wherein, stand arrangement comprises bedstead 1, bed shelves 3, bed board carriage 4, first bed board 6, second bed board 26, bed shelves carriage 7; Power set comprise loading rope 11, unloading rope 12, making leaf spring 13, braking ratchet 14, extension spring 15, reverse pulley 16, fork 17, drive ratchet 18, ratchet 19, connecting axle 20, pulley 21, support 22; Traction apparatus comprises pull rope 23, draw bar 24, traction belt 25.

In the stand arrangement, bedstead 1 can stretch up and down, and it is fixing to adjust screw 2 by bedstead.Bed shelves 3 are socketed to form each other by two kinds of different section bars of size, and scalable adjustment is adjusted the back and fixed by bed shelves trip bolt, and bed shelves 3 can and connect bent plate 10 by bedstead trip bolt 9 and be fixed on the bedstead 1, between the bedstead by 7 supportings of bed shelves carriage.Carriage is adjusted screw 8 and is contained on the bed shelves carriage 7, is used to adjust the height of bed shelves carriage 7.Respectively there is a rolling bearing at bed board carriage 4 two, and rolling bearing can roll in bed shelves 3, and bed board is divided into first bed board 6 and second bed board 26, first bed board 6 is placed on the bed board carriage 4, is screwed, by 4 supportings of bed board carriage, by the rolling bearing at two, first bed board 6 can horizontally slip; Second bed board 26 is fixed on the bed shelves 3, by 3 supportings of bed shelves.

In the power set, pulley 21 places on the bedstead 1 by support 22, and coupling spindle 20 1 ends are fixed in pulley 21 centers, and the other end is fixed in ratchet 19 centers, and like this, ratchet 19 rotates and driven pulley 21 rotations.Fork 17 1 ends are enclosed within the outside of coupling spindle 20, and another termination loads restricts 11, loads rope and walks around reverse pulley 16, and it is hinged with fork 17 formations to drive ratchet 18, and the tip is placed in the teeth groove of ratchet 19; Pulling loads rope 11 like this, loads rope by reverse pulley 16 pulling forks 17, and driving ratchet 18 driving pawls 19 on the fork 17 rotate counterclockwise, and load to traction apparatus.Also be connected to extension spring 15 on the fork 17, after relieving loaded rope 11, fork 17 was returned to initial position under extension spring 15 effects.One braking ratchet 14, the tip of braking ratchet 14 is inserted in the teeth groove of ratchet and reaches arresting purpose, connect unloading rope 12 on the braking ratchet 14, like this, pulling unloading rope 12, make the most advanced and sophisticated temporary transient ratchet 19 that breaks away from of braking ratchet 14, ratchet 19 clockwise rotates under the effect of traction apparatus, reaches the purpose of unloading, behind the relieving unloading rope 12, braking ratchet 14 is inserted in the teeth groove of ratchet 19 under the effect of making leaf spring 13 again, thus brake ratchet 19.As seen, load rope 11, can load traction apparatus, until reaching the suitable pull strength of human body by pulling; At last, by pulling unloading rope 12, can shed pull strength.

In the traction apparatus, pull rope 23 1 ends are connected on the pulley 21, the move left and right along with the rotation of pulley 21, the other end of pull rope 23 connects T shape draw bar 24, traction belt 25 is connected on the draw bar 24, like this, the move left and right of pull rope 23 causes moving of traction belt 25, thereby realizes the draw to human body.

The foregoing description is used for this utility model of explaining; rather than this utility model limited; in the protection domain of spirit of the present utility model and claim, any modification and change to this utility model is made all fall into protection domain of the present utility model.
