[0027] See also Figures 1 to 5 The present invention provides a technical solution of a pull ring for a traction bed and a method for using the pull ring for a traction bed: a pull ring for a traction bed, comprising a sliding sleeve 1 sleeved on a crossbar, a sleeve 2 connected to the lower end of the sliding sleeve 1, and a telescopic tube 21 with a hollow interior inserted in the sleeve 2, a ring-shaped handle 22 with a hollow interior connected to the end of the telescopic tube 21, and an inner cavity of the handle 22 is communicated with the telescopic tube 21. The handle 22 is ring-shaped and has a flat bottom.

[0028] It also includes a clamping mechanism disposed between the sleeve 2 and the telescopic tube 21 and a switch mechanism for opening the clamping mechanism, and the switch mechanism is disposed on the handle 22 so as to be pressed to open. The clamping mechanism is used to fix the telescopic tube 21, and the switch mechanism is used to open the clamping mechanism. The switch mechanism is disposed on the handle 22, which is convenient for one-handed operation, and the switch mechanism can be opened when the handle 22 is pulled.

[0029] The clamping mechanism includes an annular clamping groove 23 provided at equal intervals along the length direction on the inner wall of the sleeve 2 and an installation groove provided on the circumference of the telescopic tube 21. An upward elastic spring piece 24 is provided in the installation groove, and a clamping block is fixed at the end of the spring piece 24, which can be clamped into the clamping groove 23 by utilizing the elasticity of the spring piece 24. A pull rope 25 is connected to the inner side of the free end of the spring piece 24, and the ends of the pull rope 25 are connected by a pull block 26 located in the telescopic tube 21. The pull block 26 mainly applies force to the pull rope 25 in a balanced manner. Here, four installation grooves can be symmetrically provided. The spring piece 24 can be made of the same material as the telescopic tube 21, such as metal, or can be a hard plastic with a certain elasticity. The elasticity of the spring piece 24 can be adjusted according to the thickness. The clamping block is clamped in the clamping groove 23 so that it will not slide down. The clamping block is triangular and can slide out of the clamping groove 23 when the telescopic tube 21 applies force upward. The triangle may be a right triangle, with the vertical side against the bottom of the inner cavity of the slot 23, and the hypotenuse being an inclined surface extending out of the slot 23, so that when pushed upward, the inclined surface can be utilized to slide out of the slot 23 to achieve contraction.

[0030] The switch mechanism includes two main pull ropes 27 connected to the lower end of the pull block 26. The main pull ropes 27 pass through the inside of the telescopic tube 21 and the handle 22 and pass out from the bottom of the handle 22. The bottom of the handle 22 is clamped with a block-shaped switch 28 that can move up and down. The two main pull ropes 27 pass through both sides of the inner cavity of the handle 22 and are fixed on the switch 28. The bottom of the handle 22 is provided with a guide groove for the switch 28 to move upward. When the switch 28 moves upward, the main pull rope 27 is pulled, thereby pulling the pull block 26, driving the spring piece 24 and the card block to flip inward, thereby sliding out of the card slot 23.

The multi-angle mechanism includes a spherical shell 3 with an opening at the bottom fixed to the lower end of the sleeve 1 and a spherical core 31 located inside the spherical shell 3. The top and bottom of the spherical core 31 are both open, and the sleeve 2 passes through the top of the spherical core 31 upwards and then abuts against the inner cavity wall of the spherical shell 3. It also includes an elastic mechanism arranged between the sleeve 2 and the spherical shell 3. Under the action of the elastic mechanism, the sleeve 2 abuts against the inner cavity wall of the spherical shell 3 to achieve fixation. Under the action of the elastic mechanism, the inner end of the sleeve 2 abuts against the inner cavity wall of the spherical shell 3, generating extrusion and friction to achieve fixation. The sleeve 2 is pulled to break contact, and the angle adjustment can be achieved. The elastic mechanism includes a retaining ring 32 fixed on the circumference of the sleeve 2, and a receiving groove for accommodating the retaining ring 32 is provided on the ball center 31, the bottom of the receiving groove is a guide hole for the sleeve 2 to be telescopic, and the retaining ring 32 is connected to the bottom of the inner cavity of the receiving groove through a spring 33 sleeved on the sleeve 2, and the spring 33 provides elastic force. In this way, the handle 22 can stay in the air at a certain angle, which is convenient for the patient to grasp. The bottom of the sleeve 2 is in an arc shape that fits the inner cavity wall of the ball shell 3, and the top of the sleeve 2 is provided with a rubber pad 34 for increasing friction, where the end diameter of the sleeve 2 can be increased, thereby increasing the contact area with the ball shell 3, and the friction effect is better and the fixing effect is better.

[0032] The upper end of the sliding sleeve 1 is open, and a baffle 11 that can be placed on the cross bar is inserted into the open end of the sliding sleeve 1, and a bolt that prevents slipping is connected to the free end of the baffle 11. The lower end of the baffle 11 is provided with an anti-skid pad 12 that increases friction and prevents slipping, and there is a movable gap between the lower anti-skid pad 12 and the cross bar for upward and downward movement. The cross bar is square in cross section to prevent the sliding sleeve 1 from turning over. When you want to move along the length direction on the cross bar, you can directly push up the sleeve 2 to disengage the anti-skid pad 12, and then you can move. When in normal use, the anti-skid pad 12 can prevent slipping.

[0033] A method for using the pull ring for the traction bed, comprising the following steps:

[0034] Pull down the handle 22 to adjust the initial angle;

[0035] When getting up, hold the handle 22 on the corresponding side with both hands, push the handle 22 upward with the right hand to get up on one side, then push the handle 22 on the side with the left hand to shorten the overall length, and do the operations alternately until sitting up. Compared with the original fixed length, this method can directly shorten the distance when getting up, which is convenient for applying force. The traditional fixed length makes it inconvenient to apply force when getting up halfway.

[0036] Working principle: When getting up, pull the handle 22 on the corresponding side with both hands, push the handle 22 upward with the right hand to get up on one side, then push the handle 22 on that side with the left hand to shorten the overall length, and perform the operations alternately in sequence until you sit up. Compared with the original fixed length, this method can directly shorten the distance when getting up, which is convenient for applying force. The traditional fixed length is inconvenient to apply force when you are halfway up. Under the action of the spring 33, the inner end of the sleeve 2 is pressed against the inner cavity wall of the ball shell 3 and fixed by friction. In this way, the handle 22 can maintain a certain tilt angle, which is convenient for getting up.
