Description

Technical Field

[0001] This utility model relates to the field of walking aid technology, specifically to a height-adjustable seat structure for a walking aid. Background Technology

[0002] In the field of walking aid technology, walking aids, as important tools to assist walking, are widely used in the daily lives of the elderly, disabled, and those with mobility impairments. Traditional walking aids are usually equipped with a simple seat structure so that users can sit down when they need to rest. However, these seats generally suffer from the problem of inconvenient height adjustment.

[0003] Specifically, the height of existing walking aid seats is often fixed and cannot be adjusted according to the user's height or actual needs. This fixed height design not only limits the user experience for users of different heights, but also easily leads to discomfort or even injury due to an unsuitable seat height. Especially on uneven outdoor ground, fixed-height seats are even less able to meet the diverse needs of users. Utility Model Content

[0004] (I) Purpose of the utility model

[0005] In view of this, the purpose of this utility model is to propose a height-adjustable seat structure for a walking aid, which solves the problems mentioned in the background above.

[0006] (II) Technical Solution

[0007] A lifting seat structure for a walker includes two sets of support rods. Each set of support rods has two sets of sliding grooves and multiple sets of positioning grooves on one outer surface. A sliding plate is movably installed on the inner wall of each set of sliding grooves, and a connecting plate is connected to one side of the sliding plate. A seat is installed on the top of the connecting plate. An annular through groove and two sets of threaded grooves are formed on the outer surface of the sliding plate. A limit sleeve is movably installed on one outer surface of the sliding plate. A positioning pin is movably installed on the inner wall, passing through the annular through groove, and one end of the positioning pin is movably installed in the inner wall of the positioning groove.

[0008] Preferably, the limiting sleeve is fixedly connected to two sets of threaded grooves by two sets of bolts. The bolts ensure that the limiting sleeve is securely installed on the sliding plate and is not easy to loosen or fall off. This fixing method not only increases the stability of the structure, but also allows it to withstand greater external forces, thus improving the durability of the entire walker's liftable seat structure.

[0009] Preferably, a limiting plate is fixedly installed on the outer surface of the locating pin. The presence of the limiting plate can prevent the locating pin from sliding excessively or accidentally falling off, especially when no external force is applied, it can ensure that the locating pin remains in the correct position. This increases the safety and stability of the structure.

[0010] Preferably, a limiting groove is formed on the outer surface of the positioning pin, and an insert rod is movably engaged with the inner wall of the limiting groove. One end of the insert rod is connected to a limiting rod. When the insert rod is inserted into the limiting groove, it prevents the positioning pin from moving, thereby fixing the height of the seat.

[0011] Preferably, a square through groove is provided on one side of the insertion rod, and limit rings are fixedly installed at both the upper and lower ends of the insertion rod. The square through groove allows the insertion rod to undergo elastic deformation when subjected to pressure, so that its two ends can stick together and reduce its diameter, thereby making it easier to pull out from the limit groove. The presence of the limit rings can prevent the insertion rod from sliding completely into the limit groove and being unable to be pulled out when it is inserted.

[0012] Preferably, the outer end of the connecting plate is arc-shaped. The arc-shaped connecting plate reduces the sharpness of the connecting plate edge and reduces the damage that may be caused by accidental collision.

[0013] Preferably, the insertion rod is made of soft plastic, which has good elasticity and wear resistance, allowing the insertion rod to maintain its shape and function after long-term use.

[0014] As can be seen from the above technical solutions, this application has the following beneficial effects:

[0015] 1. This utility model adjusts the height of the seat 4 by pushing the sliding plate 2 up and down, so that users can adjust the seat height at any time according to their height, sitting posture preference or actual use needs, thus realizing flexible height adjustment and improving the versatility and applicability of the product.

[0016] 2. This utility model re-inserts the positioning pin into the positioning groove at the corresponding height, thus stably locking the positional relationship between the sliding plate and the support rod. This design not only ensures the stability of the seat during use but also prevents the positioning pin from accidentally slipping out of the positioning groove, thereby improving the safety and reliability of the entire walker's height-adjustable seat structure.

[0023] The following description is exemplary in nature and is not intended to limit the scope, application, or use of this disclosure. It should be understood that in all these figures, the same or similar reference numerals indicate the same or similar parts and features. The figures are merely schematic representations of the concept and principles of embodiments of this disclosure and do not necessarily show the specific dimensions and scale of the various embodiments of this disclosure. Certain details or structures of embodiments of this disclosure may be exaggerated in particular portions of certain figures.

[0024] Please see Figure 1-5 One embodiment provided by this utility model:

[0025] A lifting seat structure for a walker includes two sets of support rods 1. Each set of support rods 1 has two sets of sliding grooves 7 and multiple sets of positioning grooves 711 on one side of its outer surface. A sliding plate 2 is movably installed on the inner wall of the two sets of sliding grooves 7. A connecting plate 3 is connected to one side of the sliding plate 2. A seat 4 is installed on the top of the connecting plate 3. An annular through groove 211 and two sets of screw grooves 212 are provided on the outer surface of the sliding plate 2. A limit sleeve 5 is movably installed on one side of the outer surface of the sliding plate 2. A positioning pin 8 is movably installed on the inner wall. The positioning pin 8 passes through the annular through groove 211, and one end of the positioning pin 8 is movably installed in the inner wall of the positioning groove 711.

[0026] Furthermore, the limiting sleeve 5 is fixedly connected to two sets of threaded grooves 212 by two sets of bolts 9. The bolts 9 ensure that the limiting sleeve 5 is securely installed on the sliding plate 2, preventing it from loosening or falling off. This fixing method not only increases the stability of the structure but also allows it to withstand greater external forces, improving the durability of the entire walker's lift-up seat structure.

[0027] Furthermore, a limiting plate 811 is fixedly installed on the outer surface of the locating pin 8. The presence of the limiting plate 811 can prevent the locating pin from sliding excessively or accidentally falling off, especially when there is no external force, it can ensure that the locating pin remains in the correct position. This increases the safety and stability of the structure.

[0028] Furthermore, a limiting groove 812 is formed on the outer surface of the positioning pin 8, and an insert rod 613 is movably engaged in the inner wall of the limiting groove 812. One end of the insert rod 613 is connected to the limiting rod 6. When the insert rod 613 is inserted into the limiting groove 812, it prevents the positioning pin from moving, thereby fixing the height of the seat.

[0029] Furthermore, a square through groove 611 is provided on one side of the insertion rod 613, and limit rings 612 are fixedly installed at both the upper and lower ends of the insertion rod 613. The square through groove 611 allows the insertion rod 613 to undergo elastic deformation when subjected to pressure, so that its two ends can stick together and reduce its diameter, thereby facilitating its removal from the limit groove 812. The presence of the limit ring 612 can prevent the insertion rod 613 from sliding completely into the limit groove 812 and becoming unable to be removed.

[0030] Furthermore, the outer end of the connecting plate 3 is arc-shaped. The arc-shaped connecting plate 3 reduces the sharpness of the connecting plate edge and reduces the damage that may be caused by accidental collision.

[0031] Furthermore, the insertion rod 613 is made of soft plastic, which has good elasticity and wear resistance, allowing the insertion rod 613 to maintain its shape and function even after long-term use.

[0032] Working principle: First, the user needs to press both ends of the insertion rod 613 on the limiting rod 6. Because the insertion rod 613 has a square through groove 611, it can elastically deform under pressure, allowing its two ends to fit together, thus reducing the overall diameter to be smaller than the diameter of the limiting groove 812. Therefore, the insertion rod 613 can smoothly slide out of the limiting groove 812, at which point the positioning pin 8 is released from its locked state.

[0033] Next, the user needs to pull the positioning pin 8. After being pulled, the positioning pin 8 will slide to one side along the inner wall of the limiting sleeve 5 until it is completely disengaged from the current positioning groove 711. After this step is completed, the locking relationship between the sliding plate 2 and the bracket rod 1 is released, and the sliding plate 2 can therefore slide freely up and down in the groove 7.

[0034] At this point, the user can adjust the height of the seat 4 by pushing the sliding plate 2 up or down according to their height or actual needs. Since the sliding plate 2 and the connecting plate 3 are fixedly connected, the seat 4 will move synchronously as the sliding plate 2 moves up and down.

[0035] After adjusting the height of seat 4 to a satisfactory position, the user needs to re-lock the positional relationship between sliding plate 2 and support rod 1. At this point, the user simply inserts one end of positioning pin 8 into the corresponding positioning groove 711. To ensure that positioning pin 8 is stably locked in positioning groove 711, the user also needs to re-insert rod 613 into limiting groove 812. Since rod 613 is connected to O6, and O6 supports the two sets of O8, this prevents positioning pin 8 from accidentally sliding out of positioning groove 711.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
