The working principle of the novel traction frame for orthopedics clinic provided by the invention is as follows:
firstly, unfastening the adjusting buckles 22 on the chest strap 23, allowing the head of a user to pass through the neck guard 1, enabling the bottom end of the neck guard 1 to be sleeved on the shoulder of the user, adjusting the adjusting buckles 22 on the four connecting straps 21, changing the length of the connecting straps 21, enabling the chest strap 23 to pass through the armpits of the user, then connecting the adjusting buckles 22 on the chest strap 23 and adjusting the adjusting buckles 22, enabling the chest strap 23 to be tightly bound, and enabling the neck guard 1 to be firmly fixed on the shoulder of the user; then, the bottom ends of the four supporting arms 51 are respectively inserted into the connecting boxes 43 on the side walls of the lifting box 41, the clamping columns 46 in the connecting boxes 43 are inserted into the clamping grooves 54 on the bottom ends of the supporting arms 51, the first limiting blocks 55 are clamped with the limiting grooves 47, so that the supporting arms 51 are fixed in the connecting boxes 43, at the moment, the front supporting plate 52 is positioned under the lower jaw of a user, the rear supporting plate 53 is attached to the position of the back brain of the head of the user, then, two hands simultaneously press the knobs 42 on the two sides of the neck collar 1, the knobs 42 press the gears 48 inwards, the gears 48 push the fixed gears 72 to move, the fixed gears 72 compress the springs 73, the supporting rods 71 slide in the fixed gears 72, when the top ends of the supporting rods 71 are abutted against the inner walls of the fixed gears 72, the knob 42 cannot be pushed any more, at this time, the fixed gear 72 is separated from the rack 32, the gear 48 is completely meshed with the rack 32, then the knob 42 is rotated to drive the gear 48 to rotate inside the other side wall of the fixed gear 72, so that the lifting box 41 climbs along the sliding rod 31 and the rack 32, the sliding rod 31 slides in the fixed slot 44, the rack 32 slides in the lifting slot 45, the lifting box 41 can only slide up and down along the sliding rod 31 due to the limitation of the fixed slot 44 and the second limiting block 6, the lifting box 41 ascends to drive the supporting arm 51 to ascend, the supporting arm 51 drives the front supporting plate 52 and the rear supporting plate 53 to ascend, the front supporting plate 52 supports the lower jaw of the user, the rear supporting plate 53 supports the rear brain of the user synchronously, meanwhile, the rear supporting plate 53 automatically rotates around the supporting arm 51 according to the shape of a user's rear brain spoon, and the rear supporting plate 53 can incline for a certain angle, so that the top surface of the rear supporting plate completely fits the user's rear brain spoon, the traction process is more stable and comfortable, the front and rear positions of the head of the user are simultaneously supported, and the cervical vertebra is stretched, so that the traction on the neck is realized; when the knob 42 is released after being adjusted to a proper height, the spring 73 pushes the fixed gear 72 to slide on the surface of the support rod 71, the fixed gear 72 pushes the gear 48 to be separated from the rack 32, and at the same time the knob 42 is ejected, finally the fixed gear 72 is completely engaged with the rack 32, and the elevation box 41 is locked with the position of the rack 32. After the traction is finished, the knob 42 is turned in the above-mentioned way, the lifting structure 4 and the traction structure 5 are lowered to the bottom end of the rack 32, then the supporting arm 51 is lifted upwards, the limiting groove 47 on the clamping post 46 is separated from the first limiting block 55 in the clamping and groove 54, the supporting arm 51 slides out of the connecting box 43, the traction structure 5 is removed, then the adjusting buckle 22 on the chest strap 23 is released, and finally the neck protecting sleeve 1 is removed.
Compared with the related art, the novel traction frame for orthopedics clinic has the following beneficial effects:
the invention provides a novel traction frame for orthopaedics clinic, which can freely adjust the height of a traction structure 5 through the knob 42 according to the needs of a user, so that the traction force of a front supporting plate 52 and a rear supporting plate 53 is different, the applicability is improved, the comfort of the user in the traction process is improved, the novel traction frame is not fixedly connected with an external structure, and the novel traction frame can be freely moved by the user as long as the devices are arranged, and the user does not need to keep the same posture for sitting for a long time all the time and can not feel tired.
The foregoing description is only illustrative of the present invention and is not intended to limit the scope of the invention, and all equivalent structures or equivalent processes or direct or indirect application in other related technical fields are included in the scope of the present invention.
