Description

Technical Field

[0001] This utility model relates to the field of physiotherapy chamber technology, specifically to a rapid retraction and expansion support frame for a physiotherapy chamber. Background Technology

[0002] Physiotherapy chambers, integrating rehabilitation therapy and health maintenance, are widely used in homes, health centers, and rehabilitation centers. They provide convenient health management services through rehabilitation therapy methods such as constant temperature, air pressure, and red light. The supporting frame is the core structural component of the physiotherapy chamber, playing a crucial role in fixing the chamber's shape, ensuring operational stability, and providing safety support for the user. It directly impacts the user experience and applicable scenarios.

[0003] Traditional physiotherapy cabin support frames are mostly fixed or have complicated folding procedures. When used at home, the folding and unfolding process requires multiple people to work together or takes a lot of time, and when not in use, they take up a lot of space.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed a rapid retraction and expansion support frame for the physiotherapy chamber. Utility Model Content

[0005] The purpose of this invention is to provide a quick-release and retractable support frame for a physiotherapy chamber, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rapid retraction and expansion support frame for a physiotherapy chamber, comprising a lower frame and a sliding groove. The inner wall of the lower frame is provided with a mounting ear 1, and a support rod is hinged to the middle of the mounting ear 1 via a pin. The other end of the support rod is hinged to a mounting ear 3 via a pin, and a sliding frame is fixed to the top of the mounting ear 3. An upper frame is slidably connected to both ends of the sliding frame, and a pin hole is opened at the bottom of the upper frame. The sliding groove is located on the inner side of the upper frame, and a servo motor is installed at the middle of the front end of the upper frame. The output end of the servo motor is connected to a lead screw 1, and a synchronous pulley 1 is sleeved on the outside of the lead screw 1. A synchronous pulley 2 is connected to the outside of the synchronous pulley 1 via a synchronous belt, and a lead screw 2 passes through the middle of the synchronous pulley 2. A lead screw nut is provided on the outside of the lead screw 1 and lead screw 2, and a mounting ear 2 is connected to the outside of the lead screw nut. A connecting rod is hinged to the middle of the mounting ear 2 via a pin. A bearing is provided at the through hole on the inner side of the upper frame.

[0007] Furthermore, an auxiliary support is provided at the top front of the lower frame, and a front frame is hinged to the auxiliary support via a hinge.

[0008] Furthermore, an auxiliary support two is provided at the top rear of the lower frame, and a rear frame is hinged to the auxiliary support two via a hinge two.

[0009] Furthermore, the front frame and the rear frame are fixed with positioning pins at their tops, and the number of positioning pins and pin holes are the same.

[0010] Furthermore, the ratio of the number of mounting ears one, mounting ears two, and mounting ears three is 2:1:2, and there are two mounting ears two.

[0011] Furthermore, the first lead screw and the second lead screw have the same transmission direction and are parallel to each other. The upper frame is connected to the first lead screw and the second lead screw through bearings.

[0012] Furthermore, the sliding frame is slidably disposed in the sliding groove inside the upper frame, and the end of the connecting rod away from the second mounting ear is hinged to the sliding frame by a pin.

[0013] This utility model provides a quick-release and retractable support frame for a physiotherapy chamber, which has the following beneficial effects:

[0014] 1. This utility model uses a servo motor to drive a double lead screw synchronous transmission. The synchronous pulley one and synchronous pulley two ensure that the lead screw one and lead screw two operate in unison. With the linkage of the connecting rod and the sliding frame, the upper frame can be automatically raised and lowered without complicated manual operation. A single person can complete the folding and unfolding within 30 seconds. After folding, the upper frame and the lower frame form a compact and flat structure, which greatly reduces the space occupied and is perfectly adapted to small apartments, health centers and other spaces with limited space, so as to achieve flexible placement.

[0015] 2. The auxiliary support one and auxiliary support two of this utility model serve as rigid support components at the top of the lower frame, providing a stable installation base for hinge one and hinge two, ensuring that there is no shaking at the hinge joint when the front frame and rear frame are flipped, and that they are stacked sequentially with the lower frame after being folded up without taking up extra space. Moreover, after the positioning pin is inserted into the pin hole, a rigid connection is formed, so that the cabin frame composed of the front frame, rear frame and upper frame can bear a load of ≥150kg and have a lateral tilt of ≤0.5°, thus preventing the frame from shifting during physiotherapy.

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0022] like Figure 1 and Figure 3 As shown, a rapid retraction and expansion support frame for a physiotherapy chamber includes a lower frame 1 and a sliding groove 12. The inner wall of the lower frame 1 is provided with mounting ears 9, and a support rod 24 is hinged to the middle of mounting ears 9 via a pin. The other end of the support rod 24 is hinged to mounting ears 23 via a pin, and a sliding frame 22 is fixed to the top of mounting ears 23. An upper frame 10 is slidably connected to both ends of the sliding frame 22. A pin hole 11 is provided at the bottom of the upper frame 10. The sliding groove 12 is located inside the upper frame 10. A servo motor 13 is installed at the middle of the front end of the upper frame 10. A lead screw 14 is connected to the output end of the servo motor 13. A synchronous pulley 15 is sleeved on the outside of the lead screw 14. A synchronous pulley 17 is connected to the outside of the synchronous pulley 15 via a synchronous belt 16. A lead screw 18 is inserted through the middle of wheel 17. Lead screw nut 19 is provided on the outside of lead screw 14 and lead screw 28. A mounting ear 20 is connected to the outside of lead screw nut 19. A connecting rod 21 is hinged to the middle of mounting ear 20 by a pin. A bearing 25 is provided at the through hole on the inner side of upper frame 10. The ratio of the number of mounting ear 19, mounting ear 20 and mounting ear 3 23 is 2:1:2. There are two mounting ears 20. Lead screw 14 and lead screw 28 have the same transmission direction and are parallel to each other. Upper frame 10 is connected to lead screw 14 and lead screw 28 by bearing 25. Sliding frame 22 is slidably disposed in sliding groove 12 on the inner side of upper frame 10. The end of connecting rod 21 away from mounting ear 20 is hinged to sliding frame 22 by a pin.

[0023] The specific operation is as follows: the servo motor 13 drives the double lead screw synchronous transmission, and the synchronous pulley 15 and synchronous pulley 27 ensure that the lead screw 14 and lead screw 2 18 operate in unison. With the linkage of the connecting rod 21 and the sliding frame 22, the upper frame 10 can be automatically raised and lowered without complicated manual operation. A single person can complete the folding and unfolding within 30 seconds. After folding, the upper frame 10 and the lower frame 1 form a compact and flat structure, which greatly reduces the space occupied and is perfectly adapted to small apartments, health centers and other spaces with limited space, so as to achieve flexible placement.

[0024] like Figures 1 to 4 As shown, an auxiliary support 1 2 is provided at the top front of the lower frame 1, and a front frame 4 is hinged to the auxiliary support 1 2 via a hinge 1 3. An auxiliary support 2 5 is provided at the top rear of the lower frame 1, and a rear frame 7 is hinged to the auxiliary support 2 5 via a hinge 2 6. Positioning pins 8 are fixed at the top of the front frame 4 and the rear frame 7, and the number of positioning pins 8 and pin holes 11 is the same.

[0025] The specific operation is as follows: Auxiliary support 1 2 and auxiliary support 2 5 serve as rigid support components at the top of the lower frame 1, providing a stable installation base for hinge 1 3 and hinge 2 6, so that there is no shaking at the hinge when the front frame 4 and rear frame 7 are flipped. After being folded up, they are stacked with the lower frame 1 in sequence without taking up extra space. Moreover, after the positioning pin 8 is inserted into the pin hole 11, a rigid connection is formed, so that the cabin frame composed of the front frame 4, rear frame 7 and upper frame 10 can bear a load of ≥150kg and have a lateral tilt of ≤0.5°, avoiding frame displacement during physiotherapy.

[0026] In summary, the quick-release support frame of this physiotherapy chamber is designed so that, when in use, threaded holes are pre-set on the outer sides of both the front frame 4 and the rear frame 7, which are connected to the ABS chamber panel by stainless steel bolts. Then, the load-bearing plate at the bottom of the chamber is fixed on the top of the lower frame 1. A red light physiotherapy lamp is installed on the inner side of the rear frame 7, and the power cord of the lamp extends along the wiring channel on the inner side of the rear frame 7.

[0027] When unfolding is required, servo motor 13 drives lead screw 14 to rotate, and synchronous pulley 15 drives synchronous pulley 17 and lead screw 18 to rotate synchronously via synchronous belt 16. Lead screw nuts 19 on lead screw 14 and lead screw 18 move axially towards each other, pushing connecting rod 21 through mounting ear 20, causing sliding frame 22 to slide along the sliding groove 12 on the inner side of upper frame 10 to both ends. Support rod 24 is pushed through mounting ear 3 23, causing support rod 24 to rotate around mounting ear 9, lifting upper frame 10. When upper frame 10 reaches a certain height, manual... The front frame 4 rotates upward synchronously around the hinge 3 of the auxiliary support 1 2 and the rear frame 7 rotates upward synchronously around the hinge 6 of the auxiliary support 2 5, so that the pin hole 11 at the bottom of the upper frame 10 is aligned with the positioning pin 8 at the top of the vertically erected front frame 4 and rear frame 7. Then, the servo motor 13 is controlled to rotate in the opposite direction, driving the lead screw nut 19 to move in the opposite direction. Through the connecting rod 21, the sliding frame 22 is pulled, so that under the thrust of the support rod 24, the positioning pin 8 is inserted into the pin hole 11, completing the mechanical locking. At this time, the front frame 4, rear frame 7 and upper frame 10 form the cabin support skeleton.

[0028] When it needs to be folded up, the servo motor 13 rotates in the forward direction, causing the support rod 24 to lift the upper frame 10. During the lifting of the upper frame 10, the positioning pin 8 disengages from the pin hole 11. The front frame 4 and the rear frame 7 naturally swing down around the hinge 1 3 and hinge 2 6 under the action of gravity, folding inward and fitting against the upper frame 1. Then, the servo motor 13 is controlled to rotate in the reverse direction, causing the support rod 24 to lift the upper frame 10 down, forming a flat structure with the lower frame 1, thus completing the storage. The folded frame occupies less than half the space and can be placed close to the wall, which is suitable for the space optimization needs of small homes or health centers.

Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
