[0040] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0041] The present application provides a folding treatment chair, which is used to solve the problem of how to adjust the width of the treatment chair according to the body type of a patient.

[0042] Referring to Figure 1 , Figure 1 Fig. 2 is a perspective view of a folding treatment chair in a folded state according to an embodiment of the present application. The folding treatment chair comprises a seat 1, a backrest 2 and four widening pieces 3.

[0043] The seat 1 and the backrest 2 both have a seat surface 4.

[0044] Two of the widening pieces 3 correspond to the seat 1 and are rotatably connected to the two sides of the width of the seat 1. The other two widening pieces 3 correspond to the backrest 2 and are rotatably connected to the two sides of the width of the backrest 2. The widening piece 3 has a widening surface 31.

[0045] The rotation trajectory of the widening member 3 includes an unfolded position and a folded position. When the widening member 3 is in the unfolded position, the widened surface 31 is flush with the seat surface 4 of the corresponding seat 1 or backrest 2. When the widening member 3 is in the folded position, the widening member 3 is located below the corresponding seat 1 or backrest 2.

[0046] The widening member 3 has a locking structure 5 at the rotatable connection between it and the seat 1 or the backrest 2. The locking structure 5 is used to fix the widening member 3 to the seat 1 or the backrest 2 so as to lock the widening member 3 in the unfolded position or the folded position.

[0047] When using the folding treatment chair described above, the initial position of the widening component 3 is the folded position. If the patient is overweight, simply unlock the locking structure 5 to rotate the widening component 3 from the folded position to the unfolded position, and then unlock the locking structure 5 again to lock the widening component 3 in the unfolded position, thus widening the seat 1 and the backrest 2 of the chair surface 4. After the treatment, if the next patient does not require widening, repeat the above steps to re-lock the widening component 3 in the folded position. It can be seen that this folding treatment chair can be widened according to the patient's body size, ensuring that each patient receives the best sitting or lying experience, while avoiding discomfort or safety hazards caused by size mismatch. When widening is not needed, the widened part of the treatment chair can be folded back to a compact state, minimizing the space occupied in the treatment room and facilitating daily operations and rapid response in emergencies for medical personnel.

[0048] See Figure 1 and Figure 2 As shown, Figure 2 This is a side view of the folding treatment chair in one embodiment. In one implementation of the locking structure 5, the locking structure 5 includes a fixed base 51, a swing arm 52, and a locking pin 53. The fixed base 51 is fixed to the seat 1 or backrest 2 by welding or screwing. A rotating shaft 511 is provided on the fixed base 51 by welding or screwing. The fixed base 51 also has a first positioning hole 512 and a second positioning hole 513 arranged annularly around the rotating shaft 511. One end of the swing arm 52 is rotatably connected to the fixed base 51 via the rotating shaft 511, and the other end is fixed to the widening member 3 by welding or screwing. The swing arm 52 has an alignment hole 521. When the alignment hole 521 is opposite to and communicates with the first positioning hole 512, the widening member 3 is in the unfolded position; when the alignment hole 521 is opposite to and communicates with the second positioning hole 513, the widening member 3 is in the folded position. Figure 2The widened member 3 on the left side is in the folded position, and the widened member 3 on the right side is in the unfolded position. The locking pin 53 is used to penetrate the alignment hole 521 and the first positioning hole 512 or the second positioning hole 513 opposite to the alignment hole 521, so as to lock the widened member 3 in the unfolded position or the folded position. In this way, the widened member 3 can be quickly locked in the unfolded position or the folded position by only inserting the locking pin 53 into the first positioning hole 512 or the second positioning hole 513. Conversely, if the position locking of the widened member 3 is to be released, the locking pin 53 can be pulled out of the first positioning hole 512 or the second positioning hole 513. It can be seen that the locking and unlocking operations of the widened member 3 are simple and convenient for medical staff to quickly operate, greatly reducing the operation burden of medical staff.

[0049] Referring to Figure 2 and Figure 3 , as shown in Figure 3 , the cross-sectional view of the locking structure in the embodiment, in one embodiment of the locking pin 53, the locking pin 53 includes a connecting barrel 531 and a pin shaft 532. The connecting barrel 531 is fixedly arranged at the alignment hole 521 of the swing arm 52 by welding or integral connection. The connecting barrel 531 has a sliding groove 5311 coaxially distributed and communicated with the alignment hole 521. The sliding groove 5311 has a clearance hole 5312 at the bottom. The pin shaft 532 includes a plug-in part 5321, a sliding part 5322 and a handle part 5323 connected in sequence. The plug-in part 5321 is used to penetrate the alignment hole 521 and the first positioning hole 512 or the second positioning hole 513 opposite to the alignment hole 521. The sliding part 5322 is slidably connected in the sliding groove 5311 along the axial direction of the sliding groove 5311. The handle part 5323 penetrates the clearance hole 5312 and is located outside the connecting barrel 531. In this way, the locking pin 53 is connected to the swing arm 52 through the connecting barrel 531, which can effectively avoid the pin shaft 532 of the locking pin 53 from falling off and being lost, affecting the normal use of the locking pin 53. In combination with the sliding part 5322, the pin shaft 532 can be always coaxially distributed with the alignment hole 521, which facilitates the plug-in part 5321 to quickly penetrate the alignment hole 521 and the first positioning hole 512 or the second positioning hole 513, thereby further reducing the operation burden of medical staff. The handle part 5323 can facilitate medical staff to exert force to pull out the plug-in part 5321 from the first positioning hole 512 or the second positioning hole 513.

[0050] In addition to the above-mentioned embodiments, the locking pin 53 can also directly use the existing pin. Or the pin shaft 532 can directly use the existing pin.

[0051] Referring to Figure 3As shown, on the basis of the above embodiment, the locking pin 53 further comprises an elastic member 5324. The elastic member 5324 is located in the sliding groove 5311. The two ends of the elastic member 5324 are connected with the groove bottom of the sliding groove 5311 and the sliding part 5322 respectively, and the elastic member 5324 is used to drive the sliding part 5322 to move towards the fixed seat 51. In this way, when it is needed to change the unfolded position or the folded position, the elastic member 5324 can be compressed by pulling the handle part 5323 away from the fixed seat 51 to pull out the plug-in part 5321 from the first positioning hole 512 or the second positioning hole 513, and then the swing arm 52 is rotated to make the alignment hole 521 and the first positioning hole 512 or the second positioning hole 513 position relative and communicate, so that the plug-in part 5321 of the pin shaft 532 can automatically penetrate the alignment hole 521 and the first positioning hole 512 or the second positioning hole 513 under the elastic force of the elastic member 5324, thereby automatically locking the widened member 3 in the unfolded position or the folded position. It can be seen that the elastic member 5324 can further facilitate medical staff to quickly lock or unlock the widened member 3, thereby further reducing the operation burden of medical staff.

[0052] The above-mentioned elastic member 5324 can use existing compression springs and other components with elastic force.

[0053] Referring to Figure 3 As shown, in one embodiment of the connecting barrel 531, the connecting barrel 531 comprises a ring-shaped main member 5313 and a limiting cover 5314. One end of the ring-shaped main member 5313 is fixed to the alignment hole 521 of the swing arm 52 by welding or integral connection. The limiting cover 5314 is screwed on one end of the ring-shaped main member 5313 and forms a sliding groove 5311 with the ring-shaped main member 5313. The limiting cover 5314 has a clearance hole 5312 in the middle. In this way, when installing the locking pin 53, only need to insert the plug-in part 5321 and the sliding part 5322 of the pin shaft 532 into the sliding groove 5311, then sequentially sleeve the elastic member 5324 and the limiting cover 5314 on the handle part 5323, and finally screw the limiting cover 5314 and the ring-shaped main member 5313, which can be completed. It can be seen that the connecting barrel 531 is detachable, which can facilitate the subsequent replacement of parts such as the pin shaft 532 and the elastic member 5324, thereby saving costs.

[0054] Referring to Figure 1 As shown, on the basis of any of the above embodiments, the folding treatment chair further comprises a leg rest 6. The leg rest 6 is rotationally connected to one side of the chair seat 1 away from the chair back 2. The rotationally connected part of the leg rest 6 and the chair seat 1 also has a locking structure 5, and the locking structure 5 is also used to fix the leg rest 6 and the chair seat 1. It can be seen that the leg rest 6 also has two states of folding and unfolding, and when the leg rest 6 is unfolded, it can lengthen the chair seat 1 to meet the use requirements of patients; and the leg rest 6 and the widened member 3 use the same locking structure 5 to lock the leg rest 6 in the folded position or the unfolded position, which can facilitate mass production and save costs.

[0055] Referring to Figure 1 and Figure 4 as shown, Figure 4 is a perspective view of the folding treatment chair in the unfolded state in the embodiment, and on the basis of any of the above embodiments, the folding treatment chair further comprises a supporting base frame 7. The supporting base frame 7 is provided with at least two limiting tooth grooves 71, and each limiting tooth groove 71 is uniformly distributed along the length direction of the supporting base frame 7. The chair seat 1 is fixed on the supporting base frame 7 by welding or screwing or the like. The side of the chair back 2 close to the chair seat 1 is rotationally connected to the supporting base frame 7. The bottom surface of the chair back 2 is rotationally connected with a supporting rod 8. The folding treatment chair has an unfolded state and a folded state. In the unfolded state, the chair back 2 is placed on the supporting base frame 7, the chair surface 4 of the chair back 2 is flush with the chair surface 4 of the chair seat 1, and the supporting rod 8 is attached to the bottom surface of the chair back 2. In the folded state, the chair surface 4 of the chair back 2 is arranged at a right angle or an obtuse angle with the chair surface 4 of the chair seat 1, and the supporting rod 8 abuts against any limiting tooth groove 71. It can be seen that the chair back 2 of the utility model can be flipped relative to the chair seat 1, and the flipping angle of the chair back 2 can be limited by the cooperation of the supporting rod 8 and the limiting tooth groove 71, and the chair back 2 can also be directly placed on the supporting base frame 7, so as to realize the conversion of the patient from a sitting posture to a semi-laying or full-laying posture, greatly improving the convenience of the diagnosis and treatment process and the comfort of the patient.

[0056] Referring to Figure 1 and Figure 4 as shown, in an embodiment of the supporting base frame 7, the supporting base frame 7 comprises a top frame 72, a bottom plate 73 and at least two foot supports 74. The top of the foot support 74 is fixed to the top frame 72 by welding or screwing or the like, and the top frame 72 is used to connect the chair seat 1 and the chair back 2. Each foot support 74 is uniformly distributed along the length direction of the top frame 72, and the upper half of the foot support 74 is trapezoidal. The bottom plate 73 is fixed between the adjacent two foot supports 74 by welding or screwing or the like. In this way, the trapezoidal part of the foot support 74 can ensure the structural stability of the supporting base frame 7, and the structure design of the upper narrow and lower wide can also accommodate the widened part 3 in the folded position, reduce the occupied space, and make the folding treatment chair more compact; and the top frame 72 and the bottom plate 73 can strengthen the structural stability of the supporting base frame 7, so that the treatment chair can maintain good stability whether or not widened, avoiding any possible shaking or tilting, and ensuring the safe performance of the diagnosis and treatment process.

[0057] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
