Description

Technical Field

[0001] This utility model relates to the technical field of gua sha chairs, specifically a gua sha chair. Background Technology

[0002] With the popularization and development of traditional Chinese medicine physiotherapy techniques, scraping (gua sha), as a traditional and effective non-drug therapy, is widely used in relieving muscle fatigue, promoting blood circulation, and improving sub-health conditions. In practice, patients typically lie prone on a therapy bed or chair so that the practitioner can scrape areas such as the back, shoulders, and neck.

[0003] Existing ordinary chairs or simple physiotherapy chairs have many shortcomings: First, they lack a dedicated support structure, leaving the chest, abdomen, and upper limbs without effective support when the patient is in a prone position. Maintaining this posture for a long time can easily cause breathing difficulties and local pressure discomfort, affecting the scraping experience and treatment effect. Second, auxiliary tools are inconvenient to store. The scraping board, scraping oil, towels, and other tools required for scraping are usually scattered on the surrounding table, making them inconvenient to access and easy to lose, affecting the smoothness of operation. In addition, the ergonomic design is insufficient. The support parts are mostly made of hard cushions, which cannot adapt to individual body shapes and are not comfortable. Utility Model Content

[0004] This utility model provides a gua sha chair, aiming to solve the problems existing in the background art. The specific implementation is as follows: A gua sha chair, comprising the main body of the chair; A folding frame is rotatably connected to the chair body. The folding frame can switch between an unfolded state and a folded state. In the unfolded state, the folding frame is extended outward from the chair body and used to support the patient's limbs. In the folded state, the folding frame is folded and fitted into the chair body for storage. An adjustment component, located on the chair body, is used to control the switching of the folding frame between the unfolded state and the folded state; The adjustment assembly includes a first control lever, and sliders and teeth respectively disposed on the first control lever. There are at least two sliders, which correspond to the unfolded state and the folded state of the folding frame respectively. The chair body has a locking groove that cooperates with the teeth. When the folding frame is switched to the target state, the teeth are engaged in the locking groove to lock the position of the folding frame relative to the chair body.

[0005] As a further embodiment of this utility model, the adjustment assembly further includes a first elastic element, the two ends of which abut against the folding frame and the chair body, respectively.

[0006] As a further embodiment of this utility model, the chair body is provided with a slide rail corresponding to the slider, and the first control lever controls the slider to cooperate with the slide rail to adjust the unfolded or folded state of the folding frame.

[0007] As a further embodiment of this utility model, the slide rail includes a first limiting point and a second limiting point corresponding to the unfolded state and the folded state of the folding frame. When the slider slides to the first limiting point or the second limiting point, the teeth align with and engage with the locking groove to achieve position locking.

[0008] As a further embodiment of this utility model, the surface of the folding frame is provided with a soft pad, which is located on the side of the folding frame facing the patient and on the side opposite to the main body of the chair.

[0009] As a further embodiment of this utility model, the folding frame has a storage cavity inside, and a drawer is slidably installed in the storage cavity; The drawer is provided with sliding rails on both sides, and the inner wall of the folding frame is provided with guide grooves that match the sliding rails.

[0011] As a further embodiment of this utility model, the limiting component includes a second control rod and a limiting block disposed at the end of the second control rod. The second control rod is slidably mounted on the folding frame. When the drawer slides to the closed position, the limiting block engages in the limiting groove to lock the drawer.

[0012] As a further embodiment of this utility model, the second control lever is provided with a second elastic element, and the two ends of the second elastic element abut against the folding frame and the drawer respectively.

[0013] As a further embodiment of this utility model, the chair body includes a chest support, which is connected to the chair body via a chest support adjustment assembly. The surface contact layer of the chest support is supported by memory foam so that it deforms according to the patient's body shape and slowly rebounds when pressure is applied, thereby achieving a fit to the human body and pressure distribution.

[0014] Due to the adoption of the above technical solutions, the beneficial technical effects of this utility model are: 1. This utility model achieves dual locking of the folding frame in both unfolded and folded states by engaging the teeth with the locking groove and guiding the slider at the limit point of the slide rail.

[0017] The specific embodiments of this utility model are described below with reference to the accompanying drawings and examples: It should be noted that the structures, proportions, sizes, etc. shown in the accompanying drawings are only for the purpose of assisting those skilled in the art in understanding and reading the content disclosed in the specification, and are not intended to limit the conditions under which the present invention can be implemented. Any modifications to the structure, changes in the proportions, or adjustments to the size, without affecting the effects and purposes that the present invention can produce, should still fall within the scope of the technical content disclosed in the present invention.

[0018] Meanwhile, the terms such as "upper", "lower", "left", "right", "middle" and "one" used in this specification are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.

[0019] Combination Figures 1 to 6 As shown, this utility model provides a scraping chair, including a chair body 1, and leg pads 2, seat cushions 3, chest supports 4, head supports 5, adjustment components 7 and folding frames 8 installed on the chair body 1. The leg pads 2, seat cushions 3, chest supports 4 and head supports 5 are used to support the patient's legs, buttocks, chest and head respectively, thereby forming a complete prone physiotherapy support chair to improve the comfort and stability during scraping.

[0020] Specifically, the chair body 1 is a single load-bearing structure, which can be made of a metal frame covered with soft upholstery material to provide sufficient strength and comfort. A folding frame 8 is provided on the opposite side of the chest support 4. The folding frame 8 is rotatably connected to the chair body 1 via a hinge shaft, allowing the chair body 1 to switch between an unfolded and folded state. When the folding frame 8 rotates outwards and unfolds, it forms a horizontal support platform to support the patient's forearm, facilitating scraping operations on the patient's shoulders and back. When the folding frame 8 folds downwards and fits against the front wall of the chair body 1, it achieves compact storage, thus facilitating the transportation and storage of the scraping chair or saving space during daily use.

[0021] In this embodiment, as Figure 2 , Figure 3 As shown, the adjustment component 7 is mounted on the chair body 1 and is used to control the switching of the folding frame 8 between the unfolded state and the folded state. The adjustment component 7 includes a first control lever 71, a slider 73, a tooth 72, and a first elastic element.

[0022] Specifically, the first control lever 71 can be manually operated and is equipped with a slider 73 and a tooth 72. The folding frame 8 has a slide rail 82 corresponding to the slider 73, and the slider 73 is slidably disposed within the slide rail 82. When the user operates the first control lever 71, it causes the slider 73 to slide along the slide rail 82 and move out of the slide rail 82, thereby enabling the folding frame 8 to rotate around the hinge axis to complete the unfolding or folding action of the folding frame 8.

[0023] The slide rail 82 is provided with a first limiting point and a second limiting point corresponding to the unfolded position and the folded position of the folding frame 8, respectively. When the slider 73 slides to either limiting point, it indicates that the folding frame 8 has reached the target state. Specifically, the slide rail 82 includes a first slide rail 83 and a second slide rail 84. When the first slide rail 83 cooperates with the slider 73, it indicates that the folding frame 8 is located at the first limiting point, at which time the folding frame 8 is in the unfolded state; when the second slide rail 84 cooperates with the slider 73, it indicates that the folding frame 8 is located at the second limiting point, at which time the folding frame 8 is in the folded state.

[0024] Furthermore, the chair body 1 is provided with a hinge seat 6, the folding frame 8 is hinged to the hinge seat 6, the locking groove 61 is provided on the hinge seat 6, and the folding frame 8 is provided with a connecting seat 81, which is hinged to the hinge seat 6. The teeth 72 on the first control rod 71 correspond to the locking groove 61 on the hinge seat 6, and the two ends of the first elastic member abut against the connecting seat 81 and the hinge seat 6 respectively. Under the action of the first elastic member, the teeth 72 always tend to move towards the locking groove 61. When the folding frame 8 is in position, the teeth 72 automatically engage in the locking groove 61, thereby limiting the position of the folding frame 8, preventing it from accidentally loosening during load-bearing, and thus improving the support stability of the folding frame 8.

[0025] Preferably, the first elastic element is a first spring 74, with its two ends connected to the connecting seat 81 and the hinge seat 6, respectively. When the first control lever 71 loses the action of external force, the first spring 74 drives the first control lever 71 to reset, thereby realizing the conversion between the unfolded state and the folded state of the folding frame 8.

[0026] To facilitate the operation of the first control lever 71, a first control wheel 75 is provided at the end of the first control lever 71. The first control wheel 75 is axially mounted on the first control lever 71, and the diameter of the first control wheel 75 is larger than that of the first control lever 71, so as to prevent the first control lever 71 from moving out of the hinge seat 6 when it is reset.

[0027] In this embodiment, to improve the convenience of gua sha operation, the folding frame 8 is provided with a storage cavity, in which a drawer 86 is slidably installed. The drawer 86 is used to centrally store gua sha boards, gua sha oil, towels and other physiotherapy tools, thereby avoiding the items from being scattered and improving the efficiency of use.

[0028] Specifically, the drawer 86 is provided with sliding guide rails on both sides, and the inner wall of the folding frame 8 is provided with matching guide grooves at corresponding positions. The sliding guide rails slide smoothly along the guide grooves to realize the push-pull opening and closing of the drawer 86.

[0029] Furthermore, to prevent the drawer 86 from accidentally sliding out during the movement of the chair body 1 or the folding frame 8, the folding frame 8 is also provided with an elastic limiting component 9, and the drawer 86 has a limiting groove. When the drawer 86 slides to the fully closed position, the elastic limiting component 9 engages in the limiting groove to achieve automatic positioning and locking of the drawer 86. The limiting component 9 includes a second control rod 92, a limiting block 93 at its end, and a second elastic element. The folding frame 8 has a through hole 87, and the second control rod is slidably disposed in the through hole 87. When the drawer 86 slides to the closed position, the limiting block 93 engages in the limiting groove to lock the drawer 86.

[0030] In this embodiment, the second control lever is provided with a second elastic element, the two ends of which abut against the folding frame 8 and the drawer 86, respectively. When the user pushes the drawer 86 fully into the closed position, the side wall of the drawer 86 pushes the limiting block 93 to compress the second elastic element. When the limiting block 93 aligns with the limiting groove, the second elastic element releases its elastic force, causing the limiting block 93 to automatically spring into the limiting groove, thereby completing the automatic locking of the limiting component 9. When it is necessary to remove the drawer 86, the second control lever 92 can be manually moved to disengage the limiting block 93 from the limiting groove, and the drawer 86 can then be pulled out.

[0031] Preferably, the second elastic element is a second spring 94, with both ends of the second spring 94 connected to the folding frame 8 and the limiting block 93 respectively. When the second control rod 92 loses its external force, the second spring 94 drives the limiting block 93 to reset, thereby causing the limiting block 93 to automatically spring into the limiting groove, thus completing the automatic locking of the limiting component 9.

[0032] To facilitate the operation of the second control lever 92, a second control wheel 91 is provided at the end of the second control lever 92. The second control wheel 91 is axially mounted on the second control lever 92, and the diameter of the second control wheel 91 is larger than that of the second control lever 92, so as to prevent the second control lever 92 from moving out of the folding frame 8 when it is reset.

[0033] In this embodiment, the chest support 4 is placed on the chair body 1 corresponding to the patient and is used to support the chest or upper abdomen when the user is in a prone position for back scraping, thereby reducing abdominal pressure and improving breathing smoothness.

[0034] Specifically, the chest support 4 is adjustablely connected to the chair body 1 via a chest support adjustment assembly. The chest support adjustment assembly can employ conventional adjustment mechanisms such as a sliding rail lifting structure, an angle adjustment hinge, or a pneumatic lifting rod to adjust the height and / or tilt angle of the chest support to suit users of different body types.

[0035] In this embodiment, the specific structure of the chest support adjustment component can refer to common seat height or angle adjustment devices in the prior art, and its basic working principle is well known to those skilled in the art. Therefore, this document will not elaborate on the common technical details such as its internal transmission and locking mechanism.

[0036] The surface contact layer of the chest support is made of memory foam material, preferably with a thickness of 30–50 mm. Memory foam has slow rebound properties, which can adaptively deform according to the user's body shape when compressed and slowly return to its original shape, thereby achieving a close fit and pressure distribution, and thus significantly improving the comfort of long-term physiotherapy.

[0037] Preferably, the memory foam is covered with a removable, antibacterial, and breathable fabric layer, which facilitates the cleaning and replacement of the fabric layer.

[0038] Many other changes and modifications can be made without departing from the concept and scope of this utility model. It should be understood that this utility model is not limited to the specific embodiments, and the scope of this utility model is defined by the appended claims.
