Abstract
Description
Technical Field
[0001] This invention relates to the field of postoperative rehabilitation walking devices, specifically to a postoperative rehabilitation walking device. Background Technology
[0002] During the postoperative rehabilitation phase, patients need to use assistive walking devices to restore limb function and avoid complications caused by prolonged bed rest. Among existing assistive walking devices, traditional wheelchairs have insufficient safety because the center of gravity is concentrated in the front half, and the patient's weight acting on the handles can easily cause them to tilt backward.
[0003] To address this issue, Chinese invention patent CN221731466U discloses a postoperative rehabilitation walking device with anti-tipping function. It stabilizes the center of gravity through optimized segmented tilt design of the frame and incorporates foldable brackets and storage components to provide auxiliary support, storage, and temporary item placement. However, existing technologies still have significant shortcomings: firstly, they lack a visual warning structure for low-light environments, making patients susceptible to collisions in dimly lit settings; secondly, the components rely on screws and hinges for assembly, requiring tools for disassembly and maintenance, making the process cumbersome; and thirdly, locking and unlocking depend on a manual locking mechanism, resulting in poor adaptability for patients with limited postoperative mobility.
[0004] Based on the above-mentioned shortcomings, there is an urgent need to develop a postoperative rehabilitation walking device that takes into account safety, convenience, and operability to meet the actual needs of postoperative rehabilitation scenarios. Summary of the Invention
[0005] The present invention aims to solve one of the technical problems existing in the prior art.
[0006] This application provides a postoperative rehabilitation walking device, including a seat cushion, a pair of side frames, a pair of support rods, a pair of connecting rods, and a pair of locking components. The locking components include a locking frame and a torsion spring. The connecting rods are hollow, with a locking rod fixed therein. The locking components are provided with a locking hook and an unlocking plate. The torsion spring applies force to the locking hook to lock it with the locking rod. The locking components are hinged to the support rods. The unlocking plate is used to release the locking hook from the locking rod.
[0007] It also includes a pair of indicators and a pair of mounting slots, with the pair of mounting slots respectively provided on each side frame for mounting the indicators.
[0008] The indicator includes a light-emitting element and a mounting cylinder with a reflective ring fixed on the top. The light-emitting element is floatingly mounted in the mounting cylinder via a floating quick-release assembly. The mounting cylinder can be detachably assembled into the mounting groove via a rotating quick-release assembly. After the mounting cylinder is inserted into the mounting groove, rotating it in the forward direction can achieve dual locking of axial and circumferential degrees of freedom. Pressing the light-emitting element can release the circumferential restriction between the mounting cylinder and the mounting groove, and reversing the mounting cylinder can release the axial restriction.
[0009] The floating quick-release assembly includes a floating column and an inner sleeve. The inner sleeve is fixedly installed at the bottom of the mounting cylinder and is open from top to bottom. A bifurcated groove is opened on its inner peripheral wall. A lifting spring is provided between the top end and the bottom of the light-emitting element. The floating column is floatingly inserted into the inner sleeve. Its top end is fixedly connected to the light-emitting element. A limiting slider that slides with the bifurcated groove is fixedly installed on the peripheral wall. The bifurcated groove includes a main groove and a branch groove. The main groove is only open at the lower end. The branch groove is open at the top end and inclined at the lower end, connecting to the middle of the main groove.
[0010] The floating quick-release assembly also includes a limiting groove and a limiting post. The limiting groove is opened at the bottom end of the floating post, and the limiting post is fixed at the bottom end of the mounting groove. The cross-sections of the limiting groove and the limiting post are both non-circular. When the light-emitting element is pressed to release the circumferential restriction between the mounting cylinder and the mounting groove, the limiting groove and the limiting post cooperate to restrict the relative circumferential rotation between the floating post and the inner sleeve, preventing the limiting slider from sliding into the support groove.
[0011] The rotating quick-release assembly includes an annular groove, several insert plates, a limiting sleeve, several floating connectors, and several unlocking components. The annular groove is formed on the circumferential wall of the mounting groove. Each insert plate is fixedly mounted on the bottom surface of the reflector ring at circumferential intervals and has a protrusion that engages with the annular groove. The limiting sleeve is fixedly mounted on the bottom of the mounting groove, and its outer wall forms an annular cavity between itself and the circumferential wall of the mounting groove for inserting the insert plates. Each floating connector is arranged at circumferential intervals and is horizontally floating and inserted into the circumferential wall of the mounting sleeve. The circumferential wall of the limiting sleeve has several slots for inserting the outer ends of the floating connectors and several protruding shells for pressing against the inner side of the insert plates after rotation. Each unlocking component is fixedly mounted at circumferential intervals on the bottom of the light-emitting element and corresponds one-to-one with each floating connector. It is used to drive each floating connector to disengage from its corresponding slot when the light-emitting element is pressed.
[0012] The floating connector includes an outer top spring and an outer top insert block. The outer top insert block is horizontally slidably inserted into the peripheral wall of the mounting cylinder through a side groove. The outer top spring is disposed between the outer wall of the inner sleeve and the inner end of the outer top insert block.
[0013] The inner end of the external insertion top block is provided with a limiting protrusion to prevent the external insertion top block from coming out of the side groove.
[0014] Both the outer wall of the inner sleeve and the inner end of the outer top insert are provided with limiting blocks for fixing the outer top spring.
[0015] The unlocking component includes an unlocking groove and an unlocking rod. The unlocking groove extends vertically through the inner end of the outer top insert block, and a guide slope is provided on the top of its inner side wall. The unlocking rod is fixed to the bottom surface of the light-emitting component. When the light-emitting component is pressed, the unlocking rod is inserted into the unlocking groove, and after being reversed by the guide slope, it drives the outer end of the outer top insert block to disengage from the corresponding slot.
[0016] The beneficial effects of this invention are as follows:
[0017] 1. On the one hand, the automatic locking structure using a torsion spring in the locking mechanism ensures reliable engagement between the hook and the rod, preventing safety hazards caused by loose connections during use. Combined with the anti-tipping design of the frame, this further guarantees patient walking stability. On the other hand, the indicator uses a combination of a light-emitting element and a reflective ring, significantly improving the walker's visibility in low-light environments such as at night and in corridors, effectively reducing the risk of collisions and addressing the lack of low-light warning functionality in existing technologies. Simultaneously, the non-circular design of the limiting groove and limiting post prevents accidental disassembly of the light-emitting element by the patient, avoiding safety issues caused by component detachment and meeting the high safety requirements of postoperative rehabilitation scenarios.
[0018] 2. The locking mechanism features a single-step unlocking plate design, eliminating the need for complex force application and making it suitable for postoperative patients with limited mobility or weak hand strength. The indicator utilizes a collaborative structure of "rotation quick-release + floating quick-release," allowing for easy assembly and disassembly with simple "insertion + forward rotation" for locking and "press + reverse rotation" for unlocking, eliminating the need for tools and facilitating quick maintenance by patients or medical staff. Separating the luminous component requires first removing the entire indicator, satisfying maintenance needs while simplifying the process and resolving the cumbersome assembly and disassembly issues caused by existing technologies relying on screws and hinges. Furthermore, the automatic return of the floating connector's outer top spring and the force-reversing drive design of the unlocking component further reduce operational difficulty and enhance the user experience.
[0019] 3. The rotary quick-release assembly achieves axial and circumferential dual locking of the indicator through triple limiting: the engagement of the protruding part of the insert plate with the annular groove, the fitting of the outer top insert block with the slot, and the outer convex shell pressing against the insert plate. This prevents loosening or falling off during use. The bifurcated groove of the floating quick-release assembly cooperates with the limiting slider, along with the elastic support of the lifting spring, to ensure stable installation and accurate reset of the light-emitting component. The limiting protrusion and limiting block of the floating insert prevent the outer top insert block from falling out and the outer top spring from shifting, respectively, extending the service life of the assembly and solving the problems of easy loosening and easy wear of components in the existing locking structure.
[0020] 4. This application retains the anti-tipping and walking assistance functions of the existing technology, and through the design of low light warning, convenient disassembly and assembly, and anti-misoperation, it is fully adapted to the rehabilitation and nursing scenarios of postoperative patients. It not only meets the core needs of patients to walk and rest independently, but also facilitates medical staff to perform maintenance operations such as equipment cleaning and component replacement. At the same time, it takes into account the usage needs of patients with different lighting environments and different operating abilities, making it more practical and adaptable.

Detailed Implementation
[0034] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.
[0035] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.
[0036] The postoperative rehabilitation walking device provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.
[0037] Example 1:
[0038] This application provides a postoperative rehabilitation walking device, including a seat cushion 1, a pair of side frames 2, a pair of support rods 3, a pair of connecting rods 4, and a pair of locking components 5. The locking component 5 includes a locking frame 51 and a torsion spring 52. The connecting rods 4 are hollow, and a locking rod 6 is fixed therein. The locking component 5 is provided with a locking hook 7 and an unlocking plate 8. The torsion spring 52 applies force to the locking hook 7 to lock it with the locking rod 6. The locking component 5 is hinged to the support rod 3. The unlocking plate 8 is used to release the locking hook 7 from the locking rod 6.
[0039] In this embodiment of the application, a pair of indicator elements 9 and a pair of mounting slots 10 are also included. The pair of mounting slots 10 are respectively provided on each side frame 2 for mounting the indicator elements 9.
[0040] In this embodiment of the application, the indicator 9 includes a light-emitting element 11 and a mounting cylinder 13 with a reflective ring 12 fixed on the top. The light-emitting element 11 is floatingly mounted in the mounting cylinder 13 via a floating quick-release assembly 14. The mounting cylinder 13 is detachably assembled into the mounting groove 10 via a rotating quick-release assembly 15. After the mounting cylinder 13 is inserted into the mounting groove 10, rotating it in the forward direction can achieve dual locking of axial and circumferential degrees of freedom. Pressing the light-emitting element 11 can release the circumferential restriction between the mounting cylinder 13 and the mounting groove 10. Reversing the mounting cylinder 13 can release the axial restriction, thus realizing the overall disassembly of the indicator 9 (the light-emitting element 11 needs to be removed as a whole with the mounting cylinder 13 before being disassembled separately).
[0041] like Figures 1 to 6 , Figure 9 As shown, due to the above-mentioned structure, on the one hand, the locking component 5 achieves automatic locking of the locking hook 7 and the locking rod 6 through the elastic force of the torsion spring 52, without the need for additional manual locking, thus improving the structural stability of the walker and avoiding safety hazards caused by loose connections during postoperative use. The unlocking plate 8 can quickly release the lock, making operation convenient and suitable for postoperative patients with limited mobility. On the other hand, the indicator component 9 adopts a combination structure of "floating quick release + rotation quick release". During installation, only "insertion + forward rotation" is required to complete the double locking, and during overall disassembly, only "pressing + reversing" is required to unlock, without the need for tools, making it convenient for patients or medical staff to quickly replace and maintain the indicator component 9. At the same time, the light-emitting component 11 and the reflective ring 12 work together to improve the visibility of the walker in low-light environments, reducing the risk of collisions for postoperative patients while walking and further ensuring safety.
[0042] Example 2:
[0043] In this embodiment, in addition to the structural features of the aforementioned embodiments, the floating quick-release assembly 14 includes a floating column 141 and an inner sleeve 142. The inner sleeve 142 is fixedly installed at the bottom of the mounting cylinder 13 and is vertically continuous. A bifurcated groove 143 is provided on its inner peripheral wall. A lifting spring 144 is provided between the top end and the bottom of the light-emitting element 11. The floating column 141 is floatingly inserted into the inner sleeve 142. Its top end is fixedly connected to the light-emitting element 11. A limiting slider 145 that slides with the bifurcated groove 143 is fixedly installed on its peripheral wall. The bifurcated groove 143 includes a main groove 1431 and a branch groove 1432. The main groove 1431 is only continuous at its lower end. The branch groove 1432 is continuous at its top end and inclinedly connected to the middle of the main groove 1431 at its lower end.
[0044] In this embodiment of the application, the floating quick-release assembly 14 further includes a limiting groove 146 and a limiting post 147. The limiting groove 146 is formed at the bottom end of the floating post 141, and the limiting post 147 is fixedly installed at the bottom end of the mounting groove 10. The cross-sections of the limiting groove 146 and the limiting post 147 are both non-circular. When the light-emitting element 11 is pressed to release the circumferential restriction between the mounting cylinder 13 and the mounting groove 10, the limiting groove 146 and the limiting post 147 engage and cooperate, forcibly restricting the circumferential relative rotation between the floating post 141 and the inner sleeve 142, so that the limiting slider 145 cannot slide into the support groove 1432, thereby preventing the light-emitting element 11 from being disassembled alone.
[0045] like Figures 7 to 8 , Figures 10 to 11As shown, due to the aforementioned structure, the core function of the floating quick-release assembly 14 is: when the indicator 9 is installed as a whole in the mounting slot 10, the lifting spring 144, in conjunction with the limiting slider 145 and the bifurcation slot 143, ensures the floating stability of the light-emitting element 11. Simultaneously, the non-circular interlocking design of the limiting slot 146 and the limiting post 147 prevents the light-emitting element 11 from being removed separately due to postoperative patient accidental pressing, thus improving structural safety during use. When maintenance or replacement of the light-emitting element 11 is required, the indicator 9 must first be removed from the mounting slot 10 by rotating the quick-release assembly 15 (at this time, the limiting slot 146...). (After disengaging from the limiting post 147 and releasing the circumferential restriction), press the light-emitting element 11 to compress the lifting spring 144, causing the limiting slider 145 to slide down along the main groove 1431 to the connection point of the support groove 1432. Rotating the light-emitting element 11 will drive the limiting slider 145 to slide out along the support groove 1432, thus separating the light-emitting element 11 from the mounting cylinder 13. The inclined structure of the main groove 1431 and the support groove 1432 of the bifurcated groove 143, combined with the automatic reset function of the lifting spring 144, allows the light-emitting element 11 to be quickly and accurately reset and installed after disassembly, taking into account structural stability, safety of use and ease of maintenance, and adapting to the special needs of postoperative rehabilitation scenarios.
[0046] Example 3:
[0047] In this embodiment, in addition to the structural features of the aforementioned embodiments, the rotary quick-release assembly 15 includes an annular groove 151, a plurality of insert plates 152, a limiting sleeve 153, a plurality of floating connectors 154, and a plurality of unlocking components 155. The annular groove 151 is formed in the peripheral wall of the mounting groove 10. Each insert plate 152 is fixedly mounted to the bottom surface of the reflector ring 12 at circumferential intervals, and each has a protrusion 1521 that engages with the annular groove 151. The limiting sleeve 153 is fixedly mounted to the bottom of the mounting groove 10, and its outer wall forms a space between the outer wall and the peripheral wall of the mounting groove 10 for each insert plate 152 to be inserted. 2. The inserted annular cavity 1531 has floating connectors 154 spaced circumferentially and horizontally floatingly inserted into the circumferential wall of the mounting cylinder 13. The circumferential wall of the limiting sleeve 153 has several slots 1532 for the outer ends of the floating connectors 154 to be inserted, and several protruding shells 1533 for pressing against the inner side of the rotating insert plate 152. Each unlocking member 155 is fixedly installed at a distance along the circumferential direction at the bottom of the light-emitting element 11, corresponding one-to-one with each floating connector 154, and is used to drive each floating connector 154 to disengage from the corresponding slot 1532 when the light-emitting element 11 is pressed.
[0048] In this embodiment of the application, the floating connector 154 includes an outer top spring 1541 and an outer top plug 1542. The outer top plug 1542 is horizontally slidably inserted into the peripheral wall of the mounting cylinder 13 through a side groove 1543. The outer top spring 1541 is disposed between the outer wall of the inner sleeve 142 and the inner end of the outer top plug 1542.
[0049] In this embodiment of the application, the inner end of the outer top insert 1542 is provided with a limiting protrusion 1544 to prevent the outer top insert 1542 from coming out of the side groove 1543.
[0050] In this embodiment of the application, both the outer wall of the inner sleeve 142 and the inner end of the outer top insert 1542 are provided with a limiting block 1545 for fixing the outer top spring 1541.
[0051] In this embodiment of the application, the unlocking component 155 includes an unlocking groove 1551 and an unlocking rod 1552. The unlocking groove 1551 extends vertically through the inner end of the outer top insert 1542, and a guide slope 1553 is provided on the top of its inner sidewall. The unlocking rod 1552 is fixedly mounted on the bottom surface of the light-emitting component 11. When the light-emitting component 11 is pressed, the unlocking rod 1552 is inserted into the unlocking groove 1551, and after being reversed by the guide slope 1553, the outer end of the outer top insert 1542 is driven to disengage from the corresponding slot 1532.
[0052] like Figures 7 to 8 , Figures 10 to 11 As shown, due to the above-mentioned structure, the rotary quick-release assembly 15 and the floating quick-release assembly 14 complement each other: the rotary quick-release assembly 15 is responsible for the overall detachable connection between the indicator 9 and the mounting groove 10. During installation, the mounting cylinder 13 is inserted into the limiting sleeve 153, each insert plate 152 is inserted into the annular cavity 1531, and the outer ends of each outer top insert 1542 enter the inner side of each outer protrusion 1533. Then, the mounting cylinder 13 is rotated, and the outer top spring 1541 drives the outer top insert 1542 to embed into the slot 1532 of the limiting sleeve 153. With the engagement of the protrusion 1521 of the insert plate 152 with the annular groove 151 and the pressing action of the outer protrusion 1533 against the insert plate 152, the axial and circumferential dual locking of the indicator 9 is achieved. The locking structure is stable and reliable, preventing the mounting cylinder 13 from loosening or falling off during postoperative use by the patient. Unlocking Simply press the light-emitting element 11, and through the force reversal action of the unlocking rod 1552 and the guide slope 1553, all floating connectors 154 are simultaneously driven to disengage from the slot 1532. The operation is simple and efficient, and suitable for the operational capabilities of postoperative patients. At the same time, the unlocking action of the rotating quick-release component 15 and the "anti-disassembly" function of the floating quick-release component 14 work together. When the light-emitting element 11 is pressed, only the overall circumferential restriction of the indicator 9 is released, and the light-emitting element 11 will not be disassembled separately, ensuring the consistency of the operation logic. The limiting protrusion 1544 and the limiting block 1545 of the floating connector 154 respectively ensure the installation stability of the outer top connector 1542 and the outer top spring 1541, and extend the service life of the components. The overall technical solution takes into account the safety of use, structural stability and ease of maintenance, and is fully adapted to the application scenarios of postoperative rehabilitation walking devices.
