Referring to fig. 1, a cervical traction chair comprises a seat 110, a support rod 120 connected to the seat 110, wherein the support rod 120 may be relatively located at any orientation of the seat 110, in practical applications, the support rod 120 may be located at the front or the rear of the seat 110, a horizontal suspension rod 130 is disposed at the top end of the support rod 120 in a direction close to the seat 110, a slider 140 is slidably connected to the horizontal suspension rod 130, the slider 140 is slidable on the horizontal suspension rod 130 in a direction along the length extension direction of the horizontal suspension rod 130, and the support rod 120 is provided with: the adjusting assembly comprises an internal thread sleeve 210, a first connecting sleeve 220 and a transmission rod 230, wherein an external thread section is arranged on the supporting rod 120, the internal thread sleeve 210 and the external thread section are matched and connected with each other through threads, the first connecting sleeve 220 is sleeved on the internal thread sleeve 210 through a first bearing, one end of the transmission rod 230 is hinged on the first connecting sleeve 220, the other end of the transmission rod 230 is hinged on the sliding block 140, and the rotation axes of the two ends of the transmission rod 230 extend along the horizontal direction; the traction assembly comprises a second connecting sleeve 310, a take-up reel 320, a traction wire 330, a guide wheel 340 and a traction frame 350, wherein the guide wheel 340 is rotatably connected to the sliding block 140, the second connecting sleeve 310 is sleeved on the internal thread sleeve 210 through a second bearing, the second connecting sleeve 310 is located below the first connecting sleeve 220, the take-up reel 320 is arranged on the second connecting sleeve 310, one end of the traction wire 330 is wound on the take-up reel 320, and the other end of the traction wire 330 is connected to the traction frame 350 after bypassing the guide wheel 340.

As can be seen from the above description, when in use, a user can sit on the seat 110, then rotate the internal threaded sleeve 210, and meanwhile hold the second connecting sleeve 310, so that the second connecting sleeve 310 does not rotate, the internal threaded sleeve 210 moves up and down on the support rod 120 due to the matching connection between the external threaded section and the internal threaded sleeve through the threads, when the internal threaded sleeve 210 moves up, the internal threaded sleeve 210 drives the first connecting sleeve 220 to move up, and pushes the sliding block 140 to slide on the horizontal suspension rod 130 in a direction away from the support rod 120 through the transmission rod 230, when the internal threaded sleeve 210 moves down, the internal threaded sleeve 210 drives the second connecting sleeve 310 to move down, and drives the sliding block 140 to slide on the horizontal suspension rod 130 in a direction close to the support rod 120 through the transmission rod 230, so that different users can adjust the sliding block 140 to be right above the head of the user, the comfort level that the user uses traction frame 350 to pull the cervical vertebra is improved, and the stress on the horizontal direction of supporting rod 120 is reduced, so that supporting rod 120 is not easy to bend, and the structural stability and the safety in use are improved.

In the above embodiment, since one end of the transmission rod 230 is connected to the horizontal suspension rod 130 through the sliding block 140, the first connecting sleeve 220 at the other end of the transmission rod 230 cannot rotate together with the internal threaded sleeve 210, and in order to improve the use experience in use, in this embodiment, the first connecting sleeve 220 is provided with the first limiting block 221, the outer side wall of the support rod 120 is provided with the first limiting groove, the first limiting groove extends along the length direction of the support rod 120, and the first limiting block 221 extends into the first limiting groove. When the internal thread sleeve 210 rotates, the first connection sleeve 220 tends to rotate together with the internal thread sleeve 210, and the first limiting block 221 and the first limiting groove limit the rotation of the first connection sleeve 220, so that the transmission rod 230 drives the sliding block 140 to slide more smoothly.

In order to improve the use experience, in this embodiment, the second connection sleeve 310 is provided with a second limiting block 311, the outer side wall of the support rod 120 is provided with a second limiting groove, the second limiting groove extends along the length direction of the support rod 120, and the second limiting block 311 extends into the second limiting groove. The second limiting block 311 and the second limiting groove limit the second connecting sleeve 310 and the internal thread sleeve 210 to rotate together, and the second connecting sleeve 310 does not need to be held when the internal thread sleeve 210 is rotated, so that the problem that the take-up reel 320 rotates around the supporting rod 120 is solved.

In order to conveniently arrange the pulling wires 330, so that the whole body is simpler, in this embodiment, a wire guiding groove is formed in the outer side wall of the first connecting sleeve 220, the wire guiding groove extends along the length direction of the first connecting sleeve 220, and a blocking piece is arranged in the wire guiding groove. When the traction wire 330 is pulled from the take-up reel 320 to the guide wheel 340, the traction wire 330 can pass through the lead slot, and the baffle plate can limit the traction wire 330 in the lead slot, so that the traction wire 330 is not easy to drop out of the lead slot.

As an embodiment of an improvement on the internally threaded sleeve 210, a handwheel 400 is fixedly connected to an outer wall of the internally threaded sleeve 210, and a center line of the handwheel 400 and a center line of the internally threaded sleeve 210 are coincident with each other. When the inner thread sleeve 210 is rotated, a user can exert force on the hand wheel 400, and the rotation is more convenient.

As another embodiment for improving the internally threaded sleeve 210, a plurality of ribs are circumferentially disposed on the outer sidewall of the internally threaded sleeve 210, and the ribs extend along the length direction of the internally threaded sleeve 210. When the inner threaded sleeve 210 is rotated, a user can exert force on the ribs, and the ribs increase the friction of the user contacting with the inner threaded sleeve 210, so that the rotation is more convenient.

While the preferred embodiments of the present invention have been described in detail, it will be understood by those skilled in the art that the invention is not limited to the details of the embodiments shown, but is capable of various modifications and substitutions without departing from the spirit of the invention.
