Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0019] Please see Figures 1 to 4 This utility model provides a medical treatment chair, including a seat cushion 1, a back cushion 2, a foot pedal 3, a connecting plate 4, and a traction rope 5. The seat cushion 1 and the back cushion 2 are connected. One side of the connecting plate 4 is hinged to the seat cushion 1, and the other side is hinged to the foot pedal 3. The connecting plate 4 is provided with a first sliding contact point 41 and a second sliding contact point 42. The first sliding contact point 41 is located at the center of the connecting plate 4, and the second sliding contact point 42 is located on the edge of the connecting plate 4 adjacent to the hinge plate. The traction rope 5 is sequentially wound around the first sliding contact point 41 and the second sliding contact point 42. The back cushion 2 is provided with a hanging point 21 on the side away from the seat cushion 1. One end of the traction rope 5 is used to be fixedly connected to the side of the foot pedal 3 away from the connecting plate 4, and the other end is used to be detachably connected to the hanging point 21.

[0020] Specifically, one end of the traction rope 5 is fixedly connected to the foot pedal 3 at the end away from the connecting plate 4, and the other end passes through the top of the first sliding contact point 41, then passes through the second sliding contact point 42 from the back of the connecting plate 4, and extends all the way to the hook point 21.

[0021] The following is the specific process of folding the foot pedal 3 and connecting plate 4: The foot pedal 3 and connecting plate 4 are folded by pulling the traction rope 5, and then one end of the traction rope 5 is fixed through the hook point 21. The end of the traction rope 5 connected to the foot pedal 3 serves as the first force point for folding the foot pedal 3. The traction rope 5 pulls the foot pedal 3 towards the connecting plate 4, causing it to rotate, and the angle between the foot pedal 3 and the connecting plate 4 gradually decreases. Simultaneously, the second sliding contact point 42 serves as the second force point for folding the connecting plate 4. The traction rope 5 pulls the connecting plate 4 towards the bottom surface of the seat cushion 1, causing the angle between the connecting plate 4 and the seat cushion 1 to gradually decrease. Therefore, under the pulling force of the traction rope 5, the connecting plate 4 and the foot pedal 3 are stacked sequentially under the seat cushion 1, completing the folding process.

[0022] For example, hooks can be used as attachment points 21. Typically, two hooks can be provided on the back of the back pad 2 as attachment points 21. The higher hook can be used as attachment point 21 to fix the traction rope 5 after the foot pedal 3 and connecting plate 4 are folded up; the lower hook can be used as attachment point 21 to fix the traction rope 5 after the foot pedal 3 and connecting plate 4 are unfolded. The end of the traction rope 5 forms a rope loop for easy connection with the hook.

[0023] Preferably, a first roller 6 is rotatably connected to both the first sliding contact point 41 and the second sliding contact point 42, and the traction rope 5 is wound around the first roller 6. In this embodiment, the first roller 6 causes rolling friction between the traction rope 5 and the first sliding contact point 41 and the second sliding contact point 42, which greatly reduces the resistance encountered when pulling the traction rope 5.

[0024] In one feasible embodiment, the first roller 6 is recessed inward to form a limiting groove 61, which is used to accommodate the traction rope 5 and limit its position. In this embodiment, it is possible to prevent the traction rope 5 from deviating from the first roller 6 during pulling, thus avoiding the failure of the rolling connection between the first roller 6 and the traction rope 5.

[0025] In one feasible embodiment, a second roller 7 is rotatably connected to the connection between the seat cushion 1 and the back cushion 2, and the second roller 7 is used to abut against the traction rope 5. Since the attachment point 21 is located above the foot pedal 3 and the connecting plate 4, the connection between the seat cushion 1 and the back cushion 2 will come into contact with the traction rope 5 during the pulling process. Therefore, the arrangement of the second roller 7 causes rolling friction between the connection between the seat cushion 1 and the back cushion 2 and the traction rope 5, which greatly reduces the resistance encountered when pulling the traction rope 5.

[0026] In one feasible embodiment, the system further includes a hinge rod 8 and a locking member 9. The locking member 9 is disposed on the hinge rod 8. A sliding groove 11 is provided on the side of the seat cushion 1. One end of the hinge rod 8 is hinged to the connecting plate 4, and the other end is slidably connected to the sliding groove 11. The locking member 9 is used to lock the hinge rod 8 onto the sliding groove 11. In this embodiment, the hinge rod 8 and the locking member 9 are used to fix the connecting plate 4 at the desired angle. After the traction rope 5 is disconnected from the hook point 21, the user can flip the connecting plate 4 to the desired angle. Since the hinge rod 8 and the seat cushion 1 are slidably connected, the end of the hinge rod 8 slides to the desired position accordingly, and then the locking member 9 locks the hinge rod 8 onto the sliding groove 11, thus completing the fixation of the hinge rod 8.

[0027] In one feasible embodiment, the locking member 9 includes a connecting shaft 91, a stop plate 92, and a screw cap 93. The stop plate 92 and the screw cap 93 are respectively disposed at both ends of the connecting shaft 91. The stop plate 92 is slidably connected to the slide groove 11. The connecting shaft 91 is threadedly connected to the hinge rod 8. The screw cap 93 is used to screw to lock the hinge rod 8 onto the slide groove 11. Since the screw cap 93 and the hinge rod 8 are threadedly connected, when the screw cap 93 is rotated, the hinge rod 8 will move closer to the seat cushion 1, cooperating with the stop plate 92 engaged in the slide groove 11, together pressing the hinge rod 8 onto the seat cushion 1, thus completing the angle fixation of the connecting plate 4.

[0028] In one feasible embodiment, a limiting block 10 is provided at the hinge point of the foot pedal 3 and the connecting plate 4. The limiting block 10 is used to limit the angle at which the foot pedal 3 rotates relative to the connecting plate 4. In this embodiment, the limiting plate abuts against the bottom surface of the foot pedal 3. Under the action of gravity of the foot pedal 3 and the supporting action of the limiting block 10, the angle at which the foot pedal 3 rotates relative to the connecting plate 4 is limited.

[0029] In some other feasible embodiments, a number of casters are connected to the underside of the seat cushion 1, allowing the entire treatment chair to slide, and locking blocks are provided on the casters.

[0030] In some other feasible embodiments, a rotating mechanism is provided between the seat cushion 1 and the casters. The rotating mechanism allows the seat cushion 1 to rotate 1360 degrees, and can also be locked by a handbrake. Once locked, it cannot rotate, so as to better control the direction during transportation. Combined with the casters, it makes the movement smoother and less strenuous, improving the convenience and safety of transportation.

[0031] In some other feasible implementations, a lifting mechanism is provided between the seat cushion 1 and the casters, and a switch is provided on the lifting mechanism. The lifting function is changed to be operated by the accompanying person behind the treatment chair; a short press of the switch raises the chair, and a long press lowers it, without requiring the patient to stand.

[0032] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of the equivalent elements of the claims are intended to be included within this application. No reference numerals in the claims should be construed as limiting the scope of the claims.
