Description

Technical Field

[0001] The present invention relates to the field of correction equipment, in particular to a cervical vertebra traction device. Background Art Cervical spondylosis is a syndrome characterized by a range of clinical symptoms caused by degenerative cervical disc disease and cervical bone hyperplasia. Occupational factors are a contributing factor, particularly for those who work long hours at a desk, such as programmers, writers, and teachers. Furthermore, high workplace pressure and overtime put even greater strain on the cervical spine. The widespread use of smartphones has led people to look down at their devices during their leisure time, further increasing the strain on the cervical spine and increasing the risk of cervical spondylosis.

DETAILED DESCRIPTION

[0017] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0018] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention as claimed, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort shall fall within the scope of protection of the present invention.

[0019] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0020] In the description of the present invention, it should be noted that if the terms "upper", "lower", "inside", "outside", etc. appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the accompanying drawings, or is the orientation or position relationship in which the product of the invention is usually placed when in use. It is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be understood as a limitation on the present invention.

[0021] In addition, the terms "first", "second", etc., if used, are merely used to distinguish and describe, and should not be understood as indicating or implying relative importance.

[0022] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0023] In the prior art, there are various types of traction devices for treating cervical spondylosis, which are mainly divided into integrated and split types. The integrated structure is bulky and not convenient for storage; while the existing split type traction devices require the use of external tools for operation, which is difficult, labor-intensive, inconvenient to disassemble and assemble, and inefficient; and after disassembly, the various parts are independently scattered, which is not convenient for storage and carrying.

[0024] In view of this, the designer provides a cervical traction device, which not only reduces the difficulty of disassembly and assembly, reduces labor intensity, and improves disassembly and assembly efficiency, but also ensures that multiple components cooperate with each other after disassembly and assembly, and multiple components are not easily scattered around, making them easy to store and carry.

[0025] Please refer to Figures 1-10 This embodiment provides a cervical traction device, including a front support assembly 100, a rear support assembly 200, a seat frame assembly 300, a back opening assembly 400, a supporting assembly 500, a first tensile elastic assembly 600, a second tensile elastic assembly 700 and a third tensile elastic assembly 800, wherein: The front support assembly 100, the rear support assembly 200 and the open-back assembly 400 can all be detachably plugged into the seat frame assembly 300. The front support assembly 100 is connected to the seat frame assembly 300 via a first tensile elastic assembly 600. The rear support assembly 200 and the open-back assembly 400 are distributed on opposite sides of the seat frame assembly 300 and are connected to the seat frame assembly 300 via a second tensile elastic assembly 700. The supporting assembly 500 can be detachably plugged into the open-back assembly 400 and is connected to the open-back assembly 400 via a third tensile elastic assembly 800. When the front support assembly 100, the rear support assembly 200 and the open-back assembly 400 are pulled out of the seat frame assembly 300, the front support assembly 100 and the rear support assembly 200 can be folded to the bottom of the seat frame assembly 300, and the open-back assembly 400 can be folded to the top of the seat frame assembly 300; when the supporting assembly 500 is pulled out of the back assembly 400, the supporting assembly 500 can be folded to the top of the seat frame assembly 300.

[0026] As mentioned above, the cervical traction device provided in this embodiment is used as follows: Please refer to Figure 1-Figure 2 Under normal conditions, the front support assembly 100, rear support assembly 200, and backrest assembly 400 are all plugged into and fixed to the seat frame assembly 300, while the support assembly 500 is plugged into and fixed to the backrest assembly 400. The front support assembly 100 and rear support assembly 200 are located below the seat frame assembly 300, supporting the entire device. The backrest assembly 400 and support assembly 500 are located above the seat frame assembly 300. When a user sits on the seat frame assembly 300, their lower jaw rests on the support assembly 500, which supports their head and reduces the burden on their cervical spine.

[0027] Please refer to Figure 9-10When use is complete, force is applied to the front support assembly 100, the rear support assembly 200, the back opening assembly 400, and the supporting assembly 500. By overcoming the elastic forces of the first tensile elastic assembly 600, the second tensile elastic assembly 700, and the third tensile elastic assembly 800, the front support assembly 100, the rear support assembly 200, and the back opening assembly 400 are pulled away from the seat frame assembly 300 and folded relative to the seat frame assembly 300. The supporting assembly 500 is pulled away from the back assembly 400 and folded. No external tools are required, making the operation convenient. At the same time, after folding, the front support assembly 100 and the rear support assembly 200 are located at the bottom side of the seat frame assembly 300, and the back opening assembly 400 and the supporting assembly 500 are located at the top side of the seat frame assembly 300. The overall structure is compact, small in size, and occupies little space, making it easy to store and transport. When it needs to be unfolded for use, the front support assembly 100, the rear support assembly 200, and the back-opening assembly 400 are plugged into the seat frame assembly 300, and the supporting assembly 500 is plugged into the back-opening assembly 400. The operation is convenient and quick, and the corresponding elastic components are used to provide locking force, and the structure is stable and reliable.

[0028] It should be understood that the back opening assembly 400 and the supporting assembly 500 can be first pulled out and folded above the seat frame assembly 300, and then the front support assembly 100 and the rear support assembly 200 can be pulled out and folded below the seat frame assembly 300. Obviously, in other scenarios, the order of pulling out and folding the various components can be selected as needed and is not specifically limited in this embodiment.

[0029] The following embodiments illustrate the details of the cervical traction device of the present application by way of examples.

[0030] Please refer to Figures 1-10 In this embodiment, optionally, the cervical traction device includes a front support component 100, a rear support component 200, a seat frame component 300, a back-opening component 400, a supporting component 500, a first tensile elastic component 600, a second tensile elastic component 700 and a third tensile elastic component 800.

[0031] Please refer to Figures 1-6Optionally, the seat frame assembly 300 includes a seat plate body 310, a front assembly tube 320, a rear assembly tube 330, a first plug-in matrix 340, a second plug-in matrix 350, and a third plug-in matrix 360. The front assembly tube 320 and the rear assembly tube 330 are both fixedly connected to the seat plate body 310. There can be two front assembly tubes 320, both of which are fixed to the bottom of the seat plate body 310. There can be one rear assembly tube 330, with the two front assembly tubes 320 and the one rear assembly tube 330 arranged in a triangular structure. The first plug-in matrix 340 can be fixed to the front assembly tube 320 by anaerobic adhesive bonding, and the first plug-in matrix 340 can protrude below the front assembly tube 320. The second plug-in matrix 350 and the third plug-in matrix 360 can be fixed to the two ends of the rear assembly tube 330 by anaerobic adhesive bonding, respectively. The second plug-in mother body 350 may protrude from below the rear assembly tube 330 , and the third plug-in mother body 360 may be retracted above the rear assembly tube 330 .

[0032] It should be understood that when there are two front assembly tubes 320 , a first plug-in mother body 340 is installed in each front assembly tube 320 .

[0033] Please refer to Figure 1-Figure 2 In this embodiment, optionally, the front support assembly 100 includes two front support legs 110, a connecting rod 120 and two first plug-in sub-bodies 130. The two front support legs 110 are fixedly connected by the connecting rod 120. The two first plug-in sub-bodies 130 are respectively fixedly connected to the two front support legs 110 by anaerobic adhesive, and the first plug-in sub-bodies 130 can be located in the corresponding front support legs 110. The two first plug-in sub-bodies 130 can be separably plugged into and matched with the two first plug-in mother bodies 340, respectively, and the first plug-in sub-bodies 130 and the first plug-in mother bodies 340 are damped. That is, the first plug-in mother body 340 on the front assembly tube 320 can be inserted into the corresponding first plug-in sub-body 130. Through the cooperation between the first plug-in sub-body 130 and the first plug-in mother body 340, the stability of the plug-in cooperation can be improved, and it is not easy to shake or produce abnormal noise.

[0034] At the same time, the front assembly tube 320 and the front support leg 110 can be plugged in and matched through a concave-convex snap-fit structure that engages with each other. The concave-convex snap-fit structure not only has an anti-rotation effect, but also has a guiding and positioning effect, making it easier for the front support leg 110 to be accurately installed on the front assembly tube 320.

[0035] It should be noted that each front assembly tube 320 is connected to the corresponding front support leg 110 via a corresponding first tensile elastic component 600 .

[0036] Please refer to Figure 3-Figure 4Optionally, the first tensile elastic component 600 includes a first limiting body 610, a second limiting body 620, and a first elastic body 630. The first limiting body 610 and the second limiting body 620 can both be configured as spheres, and the first elastic body 630 can be a rubber band. The number of first elastic bodies 630 can be one or more, and can be designed as needed. The first limiting body 610 and the second limiting body 620 are both connected to both ends of the first elastic body 630. When there are multiple first elastic bodies 630, the multiple first elastic bodies 630 are arranged in parallel. The first limiting body 610 and the second limiting body 620 are respectively engaged with the corresponding first plug-in mother body 340 and first plug-in child body 130. That is, the first limiting body 610 is located on the side of the first plug-in mother body 340 away from the first plug-in child body 130, and the second limiting body 620 is located on the side of the first plug-in child body 130 away from the first plug-in mother body 340. The first limiting body 610 and the second limiting body 620 cannot be relatively close to each other. The first elastic body 630 passes through the first plug-in mother body 340 and the first plug-in child body 130 at the same time and is in a stretched state. The stretched first elastic body 630 can automatically lock the front support leg 110 and the front assembly tube 320.

[0037] It should be understood that when the front support assembly 100 needs to be folded, force is applied to the two front support legs 110 to pull them away from the two front assembly tubes 320. At this time, the first elastic body 630 is further stretched. Although the front support legs 110 and the front assembly tubes 320 are separated, the two are still connected together through the first elastic body 630, and are not easy to disperse, which is conducive to storage and subsequent assembly.

[0038] Please refer to Figure 5-Figure 6 In this embodiment, optionally, the rear support assembly 200 includes a rear support leg 210 and a second plug-in sub-body 220, and the second plug-in sub-body 220 can be fixedly connected to the rear support leg 210 by anaerobic adhesive. The second plug-in sub-body 220 and the second plug-in mother body 350 are detachably plugged into and matched, and the second plug-in sub-body 220 and the second plug-in mother body 350 are damped. Specifically, the second plug-in mother body 350 is plugged into the second plug-in sub-body 220. Obviously, in order to improve stability, a mutually interlocking concave and convex snap-fit structure can be formed on the rear assembly tube 330 and the rear support leg 210 to play an anti-rotation role.

[0039] Please refer to Figure 1 、 Figure 2 、 Figure 5-Figure 7Optionally, the back opening assembly 400 includes a back panel 410, two handrails 420, a support tube 430, a third plug-in sub-body 440, a fourth plug-in sub-body 450, a lifting rod 460, and a lifting mechanism 470. Two plastic fixing seats 480 are provided on the back of the back panel 410. The two fixing seats 480 are spaced apart in the width direction of the back panel 410. Each handrail 420 is provided with a sliding seat 490. The sliding seats 490 on the two handrails 420 are slidably connected to the two fixing seats 480 in the height direction of the back panel 410, and the fixing seats 480 and the sliding seats 490 can be mutually matched dovetail structures or T-shaped structures to prevent the fixing seats 480 and the sliding seats 490 from detaching in the thickness direction of the back panel 410. During disassembly, the sliding seats 490 can be slid away from the fixing seats 480, thereby detaching the two handrails 420 from the back panel 410. The support tube 430 is fixed to the back side of the back plate 410 and is located between the two fixing seats 480. The third plug-in sub-body 440 can be fixed to the bottom of the support tube 430 by anaerobic adhesive and extends out of the support tube 430. The fourth plug-in sub-body 450 can be fixed to the top of the lifting rod 460 by anaerobic adhesive and retracted into the lifting rod 460. The third plug-in sub-body 440 and the third plug-in mother body 360 are detachably plugged into each other, and the third plug-in sub-body 440 and the third plug-in mother body 360 are damped. For example, the third plug-in sub-body 440 can be inserted into the third plug-in mother body 360. The lifting rod 460 is slidably mounted in the support tube 430. The lifting mechanism 470 can be an electric push rod, a cylinder, a hydraulic cylinder, etc. The lifting mechanism 470 is fixed to the support tube 430, and the telescopic end of the lifting mechanism 470 is connected to the lifting rod 460. The lifting mechanism 470 can drive the lifting rod 460 to slide back and forth relative to the support tube 430. Since the supporting assembly 500 is installed on the lifting rod 460, it drives the supporting assembly 500 to rise and fall, and adjusts the height of the supporting assembly 500 to adapt to users of different heights.

[0040] It should be understood that the lifting mechanism 470 can be controlled by a remote control 900. The remote control 900 can be connected to the lifting mechanism 470 via a power cord, or the remote control 900 can be connected to the lifting mechanism 470 via wireless communication such as a Bluetooth module. The remote control 900 can be mounted on the front support assembly 100 and removed during use for easier operation. After use, it can be positioned on the front support assembly 100 to prevent loss. The remote control 900 can automatically adjust the height of the support assembly 500, providing flexible and convenient operation.

[0041] It should be understood that mutually engaged concave and convex snap-fit structures may be provided on the support tube 430 and the rear assembly tube 330 to play an anti-rotation guiding role.

[0042] In addition, a plurality of insertion holes 491 may be provided on the sliding seat 490 , and the armrest 420 may be plugged into the inner sides of the corresponding insertion holes 491 as needed, thereby achieving height adjustment of the armrest 420 .

[0043] Please refer to Figure 5-Figure 6 In this embodiment, the second tensile elastic component 700 optionally includes a third limiting body 710, a fourth limiting body 720, and a second elastic body 730. The third limiting body 710 and the fourth limiting body 720 can both be configured as spheres, and the second elastic body 730 can be a rubber band. The third limiting body 710 and the fourth limiting body 720 are respectively fixedly connected to the ends of the second elastic body 730. The third limiting body 710 and the fourth limiting body 720 are respectively engaged with the second plug-in sub-body 220 and the third plug-in sub-body 440. That is, the third limiting body 710 is located on the side of the second plug-in sub-body 220 away from the third plug-in sub-body 440, and the fourth limiting body 720 is located on the side of the third plug-in sub-body 440 away from the second plug-in sub-body 220. The third limiting body 710 and the fourth limiting body 720 do not approach each other. The second elastic body 730 sequentially passes through the second plug-in sub-body 220, the second plug-in mother body 350, the rear assembly tube 330, the third plug-in mother body 360, and the third plug-in sub-body 440, and the second elastic body 730 is in a stretched state. The second elastic body 730 can automatically lock the support tube 430, the rear assembly tube 330, and the rear support leg 210.

[0044] It should be understood that the rear support leg 210 and the rear assembly tube 330 can be pulled out, and the support tube 430 and the rear assembly tube 330 can be pulled out. During the pulling out process, the second elastic body 730 will be stretched, and after pulling out, the second elastic body 730 can be folded at will, thereby realizing the folding of the rear support leg 210 and the support tube 430 relative to the rear assembly tube 330. After the rear support leg 210 and the support tube 430 are folded, they can still be constrained in position by the second elastic body 730, will not disperse, and the overall structure is compact.

[0045] Please refer to Figure 1 、 Figure 7-Figure 8In this embodiment, optionally, the supporting assembly 500 includes a support rod 510, two support arms 520, a neck support 530, an enlarged tube 540, a fourth plug-in mother body 550, a fifth plug-in mother body 560 and a fifth plug-in child body 570. Among them, the support rod 510 can be set to a bent tube that is approximately 90°, and the bent part is an arc part, which is not easy to break or damage. Both support arms 520 can be rotatably mounted on both ends of the support rod 510, and each support arm 520 can be connected to the support rod 510 through a damping structure, which can ensure that the support arm 520 remains stable when it is rotated to the set position, and is not easy to shake or rotate freely. In addition, an elastic buckle can be set between the support arm 520 and the support rod 510. When the support arm 520 is rotated to the open state, the elastic buckle connects the support arm 520 and makes a clicking sound, indicating that it has been rotated into place. The neck support 530 is provided with two buckles, which are detachably connected to the two support arms 520 respectively. The neck support 530 is used to support the head. One end of the support rod 510 is detachably plugged into one end of the expansion tube 540, and the other end of the expansion tube 540 is detachably plugged into the lifting rod 460. The fourth plug-in mother body 550 and the fifth plug-in mother body 560 can both be fixed in the expansion tube 540 by anaerobic adhesive. The fourth plug-in mother body 550 is located below the fifth plug-in mother body 560. The fourth plug-in mother body 550 protrudes from the bottom of the expansion tube 540, and the fifth plug-in mother body 560 can be retracted at the top of the expansion tube 540. The fifth plug-in child body 570 can be fixed in the support rod 510 by anaerobic adhesive. The fifth plug-in child body 570 protrudes from the end of the support rod 510 for connection with the expansion tube 540. During actual assembly, the fourth plug-in mother body 550 can be plugged into the fourth plug-in sub-body 450 on the support tube 430 , and the fifth plug-in sub-body 570 can be plugged into the fifth plug-in sub-body 570 .

[0046] It is worth noting that anti-rotation concave-convex snap-fit structures can be provided between the extended tube 540 and the lifting rod 460 , as well as between the extended tube 540 and the support rod 510 .

[0047] In addition, when the support arm 520 is folded, the neck support 530 can be removed to avoid wrinkles.

[0048] Please refer to Figure 7In this embodiment, optionally, the third tensile elastic component 800 includes a fifth limiting body 810, a sixth limiting body 820, and a third elastic body 830. The fifth limiting body 810 and the sixth limiting body 820 can both be configured as spheres, and the third elastic body 830 can be configured as a rubber band. The fifth limiting body 810 and the sixth limiting body 820 are respectively fixedly connected to the ends of the third elastic body 830. The number of third elastic bodies 830 can be one or more, which is not specifically limited in this embodiment. The fifth limiting body 810 and the sixth limiting body 820 are respectively engaged with the fourth plug-in mother body 550 and the fifth plug-in sub-body 570, that is, the fifth limiting body 810 can be located on the side of the fourth plug-in mother body 550 away from the fifth plug-in sub-body 570, and the sixth limiting body 820 can be located on the side of the fifth plug-in sub-body 570 away from the fourth plug-in mother body 550. The fifth limiting body 810 and the sixth limiting body 820 will not be close to each other, and the third elastic body 830 is inserted into the expanded tube 540, and the third elastic body 830 is in a stretched state.

[0049] It should be understood that the lifting rod 460 and the expansion tube 540 can be pulled apart, and the support rod 510 and the expansion tube 540 can be pulled apart. During the pulling apart process, the third elastic body 830 is further stretched. After the pulling apart, the third elastic body 830 can be folded freely, thereby achieving the folding of the expansion tube 540 relative to the lifting rod 460 and the folding of the support rod 510 relative to the expansion tube 540. At the same time, after the lifting rod 460 and the expansion tube 540 are folded, they can still be restrained in position by the third elastic body 830, so as not to be scattered, and the overall structure is compact. After folding, the expansion tube 540 and the support rod 510 are both located above the back plate 410. Moreover, after the two support arms 520 are folded on both sides of the support rod 510, the support rod 510 can also be rotated so that the plane where the support rod 510 is located is parallel to the top surface of the seat plate body 310, thereby ensuring that the support rod 510 fits better on the top of the seat plate body 310, and making the two support arms 520 roughly the side of the seat plate body 310, and the structure volume after folding is smaller.

[0050] In addition, after the two armrests 420 are removed from the back panel 410 , the two armrests 420 are separated from the back panel 410 , and the two armrests 420 can be clamped between the support tube 430 and the seat panel body 310 to achieve the positioning of the armrests 420 .

[0051] Please refer to Figure 11 It is worth noting that the concave-convex snap-fit structure not only improves the stability of the connection position and prevents shaking and rotation, but also guides the connection of adjacent components, making it easier to insert and install. In addition, the concave-convex snap-fit structure of multiple connection positions can be set to be the same, which is convenient for processing and manufacturing.

[0052] The cervical traction device provided in this embodiment requires no external tools for assembly and disassembly, making it quick and easy to operate, with low labor intensity and high efficiency. Furthermore, after assembly and disassembly, the multiple components are essentially connected together by an elastic body, which prevents the components from becoming scattered and keeps them neatly positioned. The overall compact size facilitates storage and transportation. Furthermore, since the components remain connected even after folding, the elastic body can be used to guide subsequent assembly, shortening mating time and improving assembly efficiency.

[0053] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
