[0028] To enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0029] As Figures 1 to 6 shown, an improved walking stick chair aims to solve the problems of complex structure, inconvenient operation and unstable use in the prior art. The walking stick chair includes a main rod 1, on which a first fixing sleeve 2 and a second fixing sleeve 3 are sequentially arranged from top to bottom, and both the first fixing sleeve 2 and the second fixing sleeve 3 are fixedly installed on the main rod 1.

[0030] There are two sliding sleeves slidably connected to the main rod 1: a main sliding sleeve 4 located between the first fixing sleeve 2 and the second fixing sleeve 3, and another locking sliding sleeve 5 located above the first fixing sleeve 2. The part of the main rod 1 where the main sliding sleeve 4 is restricted to slide is between the first fixing sleeve 2 and the second fixing sleeve 3, while the locking sliding sleeve 5 can slide on the part of the main rod 1 located above the first fixing sleeve 2.

[0031] There is a seat assembly 6 movably connected between the first fixing sleeve 2 and the main sliding sleeve 4, and this assembly can be unfolded when the first fixing sleeve 2 and the main sliding sleeve 4 move away from each other and folded when they approach each other.

[0032] There is a leg assembly 7 movably connected between the second fixing sleeve 3 and the main sliding sleeve 4, and this assembly can be unfolded when the second fixing sleeve 3 and the main sliding sleeve 4 approach each other and folded when they move away from each other.

[0033] To fix and control the relative position between the main sliding sleeve 4 and the locking sliding sleeve 5, the present utility model provides a rigid connecting rod 51 for fixedly connecting the two between them. In addition, a first reset elastic member 52 is installed between the main sliding sleeve 4 and the first fixing sleeve 2. This elastic member is mainly used to elastically press down the main sliding sleeve 4, so that after the locking structure 8 is unlocked, the main sliding sleeve 4 can automatically slide down under the action of the first reset elastic member 52, so that the seat assembly 6 and the leg assembly 7 can be automatically unfolded.

[0034] More specifically, the first reset elastic member 52 is preferably a compression spring, which provides the necessary elastic force during the operation process.

[0035] A locking structure 8 is provided between the locking sliding sleeve 5 and the main rod 1 to limit and release the sliding of the locking sliding sleeve 5. The setting of this locking structure 8 enables the main sliding sleeve 4 and the locking sliding sleeve 5 to be locked in a fixed position, ensuring the stability and safety of the structure during use.

[0036] The structural design of the present utility model is simple. By the up-and-down sliding of the main sliding sleeve 4, it can drive the unfolding and folding of the seat assembly 6 and the leg assembly 7, and the operation is convenient. Through the locking structure 8 at the locking sliding sleeve 5, the locking and unlocking of the locking sliding sleeve 5 and the main sliding sleeve 4 are realized, which increases the safety and stability in use. Moreover, with such a design, there are no complex and delicate structures, the cost is relatively low, and the stability is relatively good. In addition, the present utility model utilizes the first reset elastic member 52 to elastically press the main sliding sleeve 4 downward, so that the seat assembly 6 and the leg assembly 7 can be automatically unfolded, greatly improving the convenience and efficiency of the user when unfolding and folding the walking stick chair. In short, the present utility model provides an improved walking stick chair, which has the advantages of simple structure, convenient operation, stable and safe use, and can better meet the needs of users.

[0037] After the seat assembly 6 is unfolded, the structure is stable, which can bear the weight of the user and provide a comfortable seat, while after folding, the volume is small, which is convenient for carrying and storing. The specific structure is as follows:

[0038] The seat assembly 6 includes a main seat plate 61 rotatably connected to the first fixed sleeve 2 and capable of swinging up and down, and a main support rod 62 rotatably connected to the main sliding sleeve 4. One end of the main support rod 62 is rotatably connected to the main sliding sleeve 4, and the other end is rotatably connected to the outer end of the bottom surface of the main seat plate 61, ensuring that the main seat plate 61 can obtain stable support when unfolded. In addition, side seat plates 63 are rotatably connected to both sides of the main seat plate 61, further expanding the width and comfort of the seat.

[0039] In order to support the side seat plate 63 and simplify the structure and reduce the volume after folding, the bottom surface of the side seat plate 63 is movably connected with a side connecting rod 64. The other end of the side connecting rod 64 is movably connected with a secondary support rod 65. The lower end of the secondary support rod 65 is rotatably connected to the middle part of the side of the main support rod 62, forming a stable support structure. The upper end of the secondary support rod 65 is rotatably connected with a slider 68, and the slider 68 is slidably connected to the main seat plate 61 along the length direction of the main seat plate 61, ensuring that the position can be flexibly adjusted during the unfolding and folding process.

[0040] It should be noted that the seat assembly 6 includes three seat plates: one main seat plate 61 and two side seat plates 63. The main seat plate 61 is supported by the main support rod 62, and the side seat plates 63 are supported by the side connecting rod 64 and the secondary support rod 65. With all three seat plates supported, the structure after unfolding is more stable and the support strength is higher.

[0041] In order to ensure the stability of the main seat plate 61, the upper end of the main support rod 62 is directly hinged to the bottom surface of the main seat plate 61 instead of being slidably connected thereto, so as to prevent the shaking problem that may occur in the conventional sliding connection.

[0042] More specifically, a universal joint 66 for movably connecting the lower end of the side link 64 and the auxiliary support rod 65 is provided therebetween. The introduction of the universal joint 66 makes the connection between the side link 64 and the auxiliary support rod 65 more flexible, adapting to adjustments at different angles. In addition, the upper end of the side link 64 is rotatably connected to a rotating seat 67, and the rotating seat 67 is rotatably connected to the bottom surface of the side seat plate 63, and the rotation central axes of the two are perpendicular to the side seat plate 63, thereby realizing the movable connection between the side seat plate 63 and the side link 64. This design allows the two side seat plates 63 to be folded to both sides of the main seat plate 61 during the folding process of the folding seat assembly 6, reducing the overall volume.

[0043] It should be noted that the auxiliary support rod 65 is connected between the main seat plate 61 and the main support rod 62, while the side link 64 is connected between the side seat plate 63 and the auxiliary support rod 65. This connection method ensures that all components can work together to provide stable support during the unfolding process; when folding, all components can be compactly stored, greatly improving portability and ease of use.

[0044] The leg assembly 7 is mainly used to provide stable ground support when the walking cane chair is unfolded, ensuring the safety and comfort of the user. The specific structure is as follows:

[0045] The leg assembly 7 includes a main leg 71 rotatably connected to the second fixed sleeve 3, and a first leg link 72 rotatably connected to the main sliding sleeve 4. One end of the first leg link 72 is rotatably connected to the main sliding sleeve 4, and the other end is rotatably connected to the main leg 71, forming a flexible support structure, enabling the main leg 71 to firmly support on the ground when unfolded.

[0046] More specifically, an extension rod 73 that can extend and retract along its length direction is slidably connected to the main leg 71. The extension rod 73 extends out when the leg assembly 7 is unfolded to increase the length of the main leg 71 so that it can support to the ground; after the leg assembly 7 is folded, the extension rod 73 can retract into the main leg 71 to reduce the volume after storage.

[0047] A third fixed sleeve 74 located below the second fixed sleeve 3 is also fixedly connected to the main rod 1. A second leg link 75 is rotatably connected to the third fixed sleeve 74. One end of the second leg link 75 is rotatably connected to the third fixed sleeve 74, and the other end is rotatably connected to the extension rod 73, for driving the extension rod 73 to extend and retract.

[0048] Through the above structural design, the unfolding and folding processes of the leg assembly 7 become simple and efficient, enhancing the stability and ease of use of the walking cane chair. When the user needs to rest, the leg assembly 7 can be quickly unfolded to provide stable support; when not in use, the leg assembly 7 can be easily folded to reduce the overall volume, facilitating carrying and storage.

[0049] The locking structure 8 can effectively lock the lock sliding sleeve 5 in the deployed and folded states, ensuring the stability and safety of the walking stick chair during use and storage. The specific structure is as follows:

[0050] The locking structure 8 includes an upper locking hole 11 and a lower locking hole 12 provided on the main rod 1. These two locking holes correspond to the folded and deployed states of the lock sliding sleeve 5 respectively. In addition, the locking structure 8 further includes an unlocking button 81 that is slidably connected to the lock sliding sleeve 5 in the transverse direction and can be inserted into and disengaged from the upper locking hole 11 and the lower locking hole 12.

[0051] To ensure that the unlocking button 81 has a reliable reset ability during use, a second reset elastic member 82 is provided between the unlocking button 81 and the lock sliding sleeve 5. This elastic member 82 is usually a compression spring or other devices with elastic recovery functions. It can elastically press the unlocking button 81 inward, making it automatically return to the initial position when there is no external force, ensuring the smooth operation of the unlocking button 81 during locking and unlocking.

[0052] When the unlocking button 81 is aligned with the upper locking hole 11, under the action of the second reset elastic member 82, the unlocking button 81 can be inserted into the upper locking hole 11, thereby locking the lock sliding sleeve 5 in the folded state. Similarly, when the unlocking button 81 is aligned with the lower locking hole 12, under the action of the second reset elastic member 82, the unlocking button 81 can be inserted into the lower locking hole 12, thereby locking the lock sliding sleeve 5 in the deployed state.

[0053] In actual operation, a ring-shaped seat body is connected to the unlocking button 81. The unlocking button 81 is provided on the inner circle of the seat body and extends inward. A pressing protrusion is also provided on the outer circle of the seat body, and this protrusion is located on the opposite side of the unlocking button 81. When unlocking is required, the user only needs to press the protrusion on the seat body to make the unlocking button 81 disengage from the locking hole 11.
