[0001] The present invention relates to the technical field of walkers, in particular to a push-down locking walker. Background Art

[0002] For patients who are bedridden for a long time or need orthopedic rehabilitation training, a walker is a commonly used training aid. Existing walkers are usually in the form of brackets, similar to two connected crutches, which patients can use with both hands to assist walking.

[0003] However, in actual application, we found that the existing walkers also have certain shortcomings: if the bottom of the walker is not designed with wheels, it will be difficult to move the entire walker, especially for orthopedic patients, it is difficult to lift the entire walker; if the bottom of the walker is designed with wheels, although it is convenient to move the walker, when the walker plays a supporting role and the patient's body weight acts on the walker, the whole walker is easy to slide, which can easily cause the patient to fall.

[0004] The use of wheels with a locking function can meet the above requirements at the same time. However, the existing wheels with a locking function are not friendly enough for orthopedic patients, whether they are locked by stepping on the foot or by bending over and locking with the hands.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in 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. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Example: See also Figure 1-Figure 7 A push-down locking walker comprises two U-shaped handlebars 1 and four support rods 2 arranged in parallel, such as Figure 1 As shown, the bottom ends of the two U-shaped handlebars 1 are movably inserted into the support rods 2, and the two adjacent support rods 2 on the rear side are connected by multiple connecting rods to form the frame of the walker. When in use, the patient stands between the two U-shaped handlebars 1 and holds the two U-shaped handlebars 1 with both hands.

[0021] like Figure 7 As shown, a bottom sleeve 12 is fixedly installed at the bottom end of the support rod 2, a bottom groove is opened at the bottom of the bottom sleeve 12, a ball sleeve 13 is arranged in the bottom groove, and a moving ball 14 is rotatably installed in the ball sleeve 13. Further, the ball sleeve 13 is movably arranged in the bottom groove, and is supported downward by a lower support spring 15 installed on the top wall of the bottom sleeve 12. An annular pad 16 is also fixedly installed on the side of the bottom of the bottom sleeve 12; When assisting walking, the patient's weight acts on the U-shaped handlebar 1, the support rod 2 and the bottom sleeve 12, so that the moving ball 14 and the ball sleeve 13 can move upward in the bottom sleeve 12, and the annular pad 16 can contact the ground. Through the contact between the annular pad 16 and the ground, a downward pressing and locking effect can be achieved, thereby preventing the walker from sliding and the patient from falling due to the movement of the moving ball 14 during the walking process; and when the patient only holds the U-shaped handlebar 1, only the moving ball 14 contacts the ground, making it convenient for the patient to push.

[0022] In the present invention, a baffle 4 is fixedly installed in the support rod 2, and a support spring 5 is fixedly installed between the top of the baffle 4 and the bottom end of the U-shaped handlebar 1. In addition, a vertical rod 3 is also fixedly installed at the bottom end of the U-shaped handlebar 1. The bottom end of the vertical rod 3 passes through the baffle 4 and is elastically telescopically provided with a telescopic rod 17. The friction block 18 is fixedly installed at the bottom end of the telescopic rod 17 and can contact the moving ball 14 through the top notch opened at the top of the ball sleeve 13 to further lock the position of the moving ball 14. When the U-shaped handlebar 1 moves downward relative to the support rod 2, while compressing the support spring 5, the vertical rod 3 is also driven downward, and the downward movement of the vertical rod 3 drives the friction block 18 downward, so that the friction block 18 can be in close contact with the moving ball 14, further locking the moving ball 14 to prevent it from sliding during the walking assistance process.

[0023] like Figure 3 As shown, an anti-slip plate 6 is fixedly mounted on the vertical rod 3 , and the anti-slip plate 6 is located below the baffle 4 , which can prevent the U-shaped handlebar 1 from slipping out of the support rod 2 .

[0024] In this embodiment, whether the U-shaped handlebar 1 is retracted can be manually controlled, specifically, Figure 4 , Figure 5 and Figure 6 As shown, a telescopic groove 21 is provided on the side of the bottom end of the U-shaped handlebar 1, and a clamping block 19 is movably and telescopically provided in the telescopic groove 21. A clamping groove 20 for clamping the clamping block 19 is provided on the inner wall of the support rod 2. When the clamping block 19 is located outside the support rod 2 and extends out, it can limit the retraction of the U-shaped handlebar 1; when the clamping block 19 is located outside the support rod 2 and retracts, the U-shaped handlebar 1 can retract freely; when the clamping block 19 is located at the position of the clamping groove 20 and extends out, it can lock the U-shaped handlebar 1 so that the U-shaped handlebar 1 cannot pop out again; In the present invention, the extension and retraction of the clamping block 19 is controlled by the gripping rod 26. Specifically, a partition is fixedly installed in the expansion slot 21, and a transverse spring 22 is provided between the partition and the clamping block 19. A gripping area is formed in the middle of the U-shaped handlebar 1, and a wire groove is opened inside the U-shaped handlebar 1, one end of which is connected to the telescopic groove 21, and the other end is located at the gripping area. A steel wire 23 is arranged in the wire groove, one end of the steel wire 23 passes through the partition and is fixedly connected to the block 19, and the other end is fixedly installed on the inner wall of the wire groove. In addition, an inner cavity 24 is formed perpendicular to the wire groove in the gripping area of ​​the U-shaped handlebar 1, and a pressing tongue 25 for pressing the steel wire 23 is movably inserted in the inner cavity 24. The end of the pressing tongue 25 located outside the inner cavity 24 is fixedly connected to a gripping rod 26, and the gripping rod 26 is located below the gripping area of ​​the U-shaped handlebar 1. When the gripping rod 26 is held, the pressing tongue 25 can be moved up, and the pressing tongue 25 moves up to press the steel wire 23, so that the other end of the steel wire 23 can pull the block 19, thereby retracting the block 19; otherwise, the block 19 is extended.

[0025] like Figure 6 As shown, a guide wheel is rotatably installed in the wire groove to guide the movement of the steel wire 23.

[0026] Therefore, in the present invention, by holding the gripping rod 26 , the extension and retraction of the clamping block 19 can be controlled.

[0027] like Figure 1 and Figure 2 As shown, a rotating shaft 7 is rotatably installed between two adjacent supporting rods 2 at the rear side, a mounting plate 8 is fixedly installed on the rotating shaft 7, and the mounting plate 8 is fixedly connected to a seat plate 9, and the seat plate 9 is in a vertical state in the initial state; in addition, a gear 10 is fixedly installed at the end position of the rotating shaft 7, and an L-shaped toothed plate 11 is meshed with the outer wall of the gear 10, and the L-shaped toothed plate 11 is fixedly installed on the U-shaped handlebar 1; The downward movement of the U-shaped handlebar 1 will not only further lock the moving ball 14, but will also drive the L-shaped toothed plate 11 to move. The movement of the L-shaped toothed plate 11 drives the gear 10 to rotate. The rotation of the gear 10 drives the rotating shaft 7, the mounting plate 8 and the seat plate 9 to rotate, so that the seat plate 9 rotates to a horizontal position, providing a seat function, so that it is convenient for patients to rest when they are tired during training; by locking the block 19 in the slot 20, the upward movement of the U-shaped handlebar 1 can be limited, so that the seat plate 9 can be kept in a horizontal state.

[0028] When the patient stands up, although the annular pad 16 loses its locking effect, the friction block 18 is still effective due to the locking of the clamping block 19, thereby effectively preventing the walker from sliding when the patient stands up.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
