[0049] The utility model is further described below in combination with the drawings and specific embodiments. It should be noted that the embodiments described below or the technical features thereof can be combined to form new embodiments without conflict.

[0050] First embodiment

[0051] As Figures 1-8 shown, a novel convenient storage walking aid, including left side frame assembly 10, right side frame assembly 11, front guard assembly 20, locking structure 30, limiting assembly 40 and mute assembly 50, wherein, left side frame assembly 10, right side frame assembly 11 are provided with front side pipe 120, the upper portion of the front side pipe 120 is bent to the rear side of walking aid and forms hand support part 1201, and the plastic sleeve is set on the hand support part 1201 for daily use to support and hold the hands of the user. The lower part of the front side pipe 120 has a side pipe leg for detachably connecting the supporting leg, and the side pipe leg is supported on the ground through the connecting leg.

[0052] The side pipe leg includes front side leg 1202 and rear side leg 1203, and the supporting leg includes front side supporting leg 14 and rear side supporting leg 15. When installing the walking aid, the front side leg 1202 is vertically arranged at the front side of the walking aid and detachably connected with the front side supporting leg 14; one end of the rear side leg 1203 is connected with the front side leg 1202, and the other end of the rear side leg 1203 is arranged to extend a certain distance towards the rear side of the walking aid and then bent downward, and the downward bent part is detachably connected with the rear side supporting leg 15.

[0053] Therefore, through the optimization of the upper part and the lower part of the side pipe leg, the storage area 16 is formed between the rear side leg 1203 of the side pipe leg and the hand support part 1201. The embodiment of the application omits the design of the rear side pipe of the walking aid, saves the material and design cost of the rear side pipe under the premise of maintaining the stability of the overall structure of the walking aid.

[0054] In order to improve the structural strength of the side pipe leg, a pipe support 60 is arranged between the front side leg 1202 and the rear side leg 1203, and the front side leg 1202 and the rear side leg 1203 are connected and reinforced on one side towards the storage area 16 through the pipe support 60. In addition, the front side leg 1202 and the rear side leg 1203 can also be connected and reinforced on the side towards the ground through the pipe support 60.

[0055] The front protection assembly 20 has a front protection plate 201 and a buckling structure 21, the front protection plate 201 includes a first protection plate 2010 and a second protection plate 2011, and the two ends of the first protection plate 2010 and the second protection plate 2011 are correspondingly provided as a hinged end 2012 and a buckling end 2013. The hinged end 2012 of the first protection plate 2010 is hingedly connected with the hinged end 2012 of the second protection plate 2011, and the folding and hinging between the first protection plate 2010 and the second protection plate 2011 realizes the folding and storage of the left side frame assembly 10 and the right side frame assembly 11. In addition, the buckling end 2013 of the first protection plate 2010 and the second protection plate 2011 is connected with the buckling structure 21.

[0056] More specifically, the buckling structure 21 has a first hinge 210 and a second hinge 211, one side of the first hinge 210 and the second hinge 211 is movably hingedly connected, and the other side of the first hinge 210 is fixedly connected to the end of the front protection plate 201. Since the first hinge 210 and the second hinge 211 are both processed to have a certain arc structure, the first hinge 210 and the second hinge 211 can be connected to the front side tube 120. After the first hinge 210 and the second hinge 211 are buckled on the front side tube 120, the other side of the second hinge 211 is detachably connected to the end of the front protection plate 201 by screw connection, bolt connection or buckle connection.

[0057] Therefore, through the hinged folding and optimized design of the first protection plate 2010 and the second protection plate 2011, the first protection plate 2010 and the second protection plate 2011 are quickly and conveniently detachably buckled and connected to the front side tube 120 of the left side frame assembly 10 and the right side frame assembly 11 through the buckling structure 21, thereby improving the convenience of unfolding and folding and storing between the left side frame assembly 10 and the right side frame assembly 11. In particular, the detachable and quick assembly of the buckling structure 21 at the two ends of the front protection plate 201 and the front side tube 120 facilitates the corresponding adjustment of the folding mode of the walker according to various transportation spaces, thereby improving the folding and storage flexibility of the walker.

[0058] Moreover, the front protection plate 201 can be directly locked on the front side tube 120 at any time, and the laser welding and oxidation treatment of the left side frame assembly 10 and the right side frame assembly 11 can be arranged flexibly, thereby improving the production and processing efficiency of the walker.

[0059] As shown in Figure 8 The left side frame assembly 10 and the right side frame assembly 11 are transposed and stored in the same horizontal plane, so the overall thickness of the left side frame assembly 10 and the right side frame assembly 11 after storage still maintains the thickness of the side tube of the walker.

[0060] Therefore, the folding and storing mode of the embodiment of the application is suitable for the transportation space with limited horizontal placement and wide vertical stacking height.

[0061] Moreover, the lower part of the front side tube 120 of the left frame assembly 10 can be stored in the storage area 16 of the right frame assembly 11, and the lower part of the front side tube 120 of the right frame assembly 11 can be stored in the storage area 16 of the left frame assembly 10, so that the storage structure is compact. The front guard plate 201 and the buckle structure 21 of the front guard assembly 20 and the supporting leg are also correspondingly stored in the storage area 16, so that the storage is more orderly, the storage space is fully utilized, the thickness of the stored walking aid can be kept as the thickness of the side tube of the walking aid, the occupied space of the stored walking aid is maximally saved, and the transportation cost is greatly reduced.

[0062] Preferably, the locking structure 30 has a locking piece 301, a lock tongue 302 and a pushing block 303. The locking piece 301 is substantially plate-shaped, so as to be better assembled with the front guard plate 201. The locking piece 301 has a fixed end 3010 and a buckle end 3011, and a boss 3012 is integrally formed on the side surface of the fixed end 3010 and the buckle end 3011. The first guard plate 2010 and the second guard plate 2011 are both provided with a guard plate hole 2014.

[0063] When the locking structure 30 is installed, the boss 3012 on the fixed end 3010 of the locking piece 301 is fixedly clamped on the guard plate hole 2014 of the second guard plate 2011, so that the fixed end 3010 of the locking piece 301 is fixedly connected with the second guard plate 2011. The buckle end 3011 and the boss 3012 are both provided with a sliding hole 3013, and the sliding hole 3013 penetrates the buckle end 3011 and the boss 3012.

[0064] The lock tongue 302 has a guide block 3020 matched with the sliding hole 3013 on the buckle end 3011. When the lock tongue 302 is assembled, the guide block 3020 of the lock tongue 302 is embedded in the sliding hole 3013 from the side of the boss 3012 of the buckle end 3011, so that the lock tongue 302 can be movably assembled on the boss 3012 of the buckle end 3011. In addition, the pushing block 303 is arranged on the side opposite to the boss 3012 of the buckle end 3011, and the pushing block 303 is connected with the guide block 3020 of the lock tongue 302. A user can drive the lock tongue 302 to slide along the sliding hole 3013 by pushing the pushing block 303.

[0065] In order to realize the locking of the first guard plate 2010 and the second guard plate 2011, the boss 3012 of the locking end 3011 is clamped on the corresponding guard plate hole 2014 of the first guard plate 2010, at this time, the fixed end 3010 and the locking end 3011 of the locking piece 301 are clamped on the second guard plate 2011 and the first guard plate 2010 through the boss 3012, so that the locking piece 301 is assembled on the same side of the front guard plate 201.

[0066] Since the size of the lock cover 3021 of the lock tongue 302 is smaller than the hole diameter size of the guard plate hole 2014, after the boss 3012 of the locking end 3011 is clamped on the guard plate hole 2014 of the first guard plate 2010, the lock tongue 302 can pass through the guard plate hole 2014 and be exposed on the other side of the first guard plate 2010, that is, the first guard plate 2010 is located between the locking end 3011 and the lock tongue 302 of the locking piece 301.

[0067] Then, the hand pushing block 303 on the locking end 3011 is pushed by the spring, the hand pushing block 303 drives the lock cover 3021 of the lock tongue 302, and the lock cover 3021 of the lock tongue 302 is slid to a dislocation state with the guard plate hole 2014 on the first guard plate 2010, at this time, the locking end 3011 of the locking piece 301 cannot be separated from the first guard plate 2010, and then the unfolded connection state of the first guard plate 2010 and the second guard plate 2011 is locked by the locking piece 301. When unlocking is needed, the lock cover 3021 of the lock tongue 302 is only slid to be aligned with the guard plate hole 2014 of the first guard plate 2010, and the first guard plate 2010 can be folded with the second guard plate 2011 from the side away from the locking piece 301.

[0068] By arranging the locking structure 30 on the hinged end 2012 of the first guard plate 2010 and the second guard plate 2011, when the fixed end 3010 of the locking piece 301 is fixedly connected with the second guard plate 2011, the user can drive the lock tongue 302 to slide on the locking end 3011 of the locking piece 301 and lock or unlock the first guard plate 2010 by operating the hand pushing block 303, so as to realize the purpose of quickly unfolding and locking or unlocking and folding of the first guard plate 2010 and the second guard plate 2011, and the user only needs to push and pull the hand pushing block 303, which is convenient and labor-saving.

[0069] In this way, the new convenient storage walking aid provided by the embodiment of the application is connected through the front guard plate 201 between the left side frame assembly 10 and the right side frame assembly 11, and the two ends of the front guard plate 201 are provided with the buckling structure 21, so as to quickly disassemble and assemble the front side tube 120 of the left side frame assembly 10 and the right side frame assembly 11 through the buckling structure 21 at the two ends of the front guard plate 201 correspondingly; compared with the sleeve assembly mode of the front guard plate 201 and the front side tube 120 in the prior art, the new convenient storage walking aid is more convenient to assemble, especially convenient for laser welding and oxidation treatment, and the production and processing efficiency of the walking aid is improved;

[0070] When the left frame assembly 10 and the right frame assembly 11 are quickly folded and stored through the buckling structure 21, the front guard plate 201 and the buckling structure 21 of the front guard assembly 20 and the supporting legs can be correspondingly stored in the storage area 16 formed by the supporting hand part 1201 of the front side tube 120 and the side tube supporting leg, which is more orderly, fully utilizes the storage space, and can keep the thickness of the stored walking aid as the thickness of the side tube of the walking aid; compared with the prior art in which the thickness of the folded walking aid reaches 3 to 4 times the thickness of the side tube, the occupied space of the stored walking aid is maximally saved, and at least 60% of the transportation cost is saved.

[0071] Preferably, as shown in 6 and 7, the limiting assembly 40 has a prying block 401, a limiting block 402 and a pin 403, wherein the limiting block 402 and the prying block 401 are both processed with an arc-shaped structure adapted to the surface of the front side tube 120, the limiting block 402 is fixedly connected to the surface of the front side tube 120, and the prying block 401 is movably arranged on the side surface of the front side tube 120. Figure 2 、 4

[0072] The front side tube 120 is provided with a pin hole, so that the pin 403 can penetrate the front side tube 120 from the pin hole, one end of the prying block 401 is provided with a hand prying end 4010 for a user to pry, and the other end of the prying block 401 is a sliding end 4011 connected with the pin 403. When the sliding end 4011 of the prying block 401 reciprocally prys along the surface of the front side tube 120, the pin 403 can slide axially forward and backward in the pin hole of the front side tube 120, so that the limiting end of the pin 403 extends out of the surface of the front side tube 120 and limits the connecting position of the front guard plate 201 and the front side tube 120 together with the limiting block 402, thereby avoiding the loosening problem between the front guard plate 201 and the front side tube 120, and improving the overall structural stability of the left frame assembly 10 and the right frame assembly 11 in the unfolded state, and ensuring the safety of the user.

[0073] In daily use, the pin 403 is sleeved with a telescopic spring 404, and the two ends of the telescopic spring 404 are correspondingly tightly pressed against the pin 403 and the inner wall of the front side tube 120. Therefore, when the prying block 401 is manually pried, the pin 403 retreats into the front side tube 120 and compresses the telescopic spring 404, so as to release the limiting of the front guard plate 201, and at this time, the folding operation of the front guard plate 201 can be performed; when the prying block 401 is released, the pin 403 extends out of the surface of the front side tube 120 under the elastic force of the telescopic spring 404, so as to limit the front guard plate 201 together with the limiting block 402.

[0074] ​Preferably, the mute assembly 50 has an elastic strip 501, one end of the elastic strip 501 is provided with a quick release head, and the other end is provided with a limiting sheet. The elastic strip 501 used in the embodiment of the application can be an elastic band or a telescopic spring.

[0075] The embodiment of the application selects to set a plurality of through internal positioning holes 150 in the length direction of the front side leg 14 and the rear side leg 15, and sets a positioning piece 13 on the front side leg 1202 and the rear side leg 1203 of the front side pipe 120. The positioning piece 13 is elastically arranged on the front side leg 1202 and the rear side leg 1203, and can be telescoped into the pipe hole of the front side leg 1202 and the rear side leg 1203 under the pressing of an external force.

[0076] Therefore, when the front side leg 14 is sleeved outside the front side leg 1202, the length of the front side leg 1202 inserted into the front side leg 14 and the length of the rear side leg 1203 inserted into the rear side leg 15 can be adjusted according to the use demand of the user, and then the height of the side frame of the walker is adjusted. After the height of the side frame is determined, the positioning piece 13 is aligned with the specified positioning hole 150 on the leg, and the positioning piece 13 is inserted into the specified positioning hole 150, so as to lock the assembly relationship between the leg and the leg.

[0077] When the height of the side frame of the walker needs to be adjusted, the user only needs to press the positioning piece 13, so that the positioning piece 13 is separated from the positioning hole 150 and retreats into the inner cavity of the leg, and then the length of the leg of the front side pipe 120 inserted into the pipe hole of the leg is adjusted. The leg of the front side pipe 120 moves along the inner cavity of the leg and aligns the positioning piece 13 with the specified positioning hole 150, and then the operation of inserting the positioning piece 13 into the positioning hole 150 is repeated.

[0078] In order to realize the mute purpose of the walker, a pin is arranged in the leg hole of the front side pipe 120, an end hole matched with the elastic strip 501 is arranged at the lower end of the leg, and then the first end of the elastic strip 501 is inserted into the pin inside the leg of the front side pipe 120 from the end hole at the lower end of the leg and is detachably connected to the pin. In addition, the second end of the elastic strip 501 is limited by the limiting sheet and the end hole, so as to prevent the second end of the elastic strip 501 from being separated from the lower end of the leg. Therefore, after the elastic strip 501 is assembled between the leg and the leg of the front side pipe 120, the left leg and the left leg, and the right leg and the right leg always maintain the state of being elastically pulled towards each other.

[0079] Therefore, by setting the mute assembly 50, the elastic connection between the feet and the legs of the front pipe 120 is achieved through the elastic strip 501. Even if the assembly gap between the positioning hole 150 and the positioning piece 13 increases due to wear over time, since the positioning piece 13 is arranged on the feet of the front pipe 120 and the positioning hole 150 is arranged on the legs, when the pipe feet and the legs are elastically pulled towards each other through the elastic strip 501, the positioning piece 13 and the positioning hole 150 are always in close contact regardless of whether the user is lifting or lowering the walker. Therefore, the problem of metal collision noise caused by the collision between the positioning piece 13 and the positioning hole 150 during use is avoided, the mute use effect of the walker is improved, and the user experience is improved.

[0080] Second embodiment

[0081] As shown in Figure 9 , the difference between the embodiment of the present application and the first embodiment is that the folding and storage methods of the left side frame assembly 10 and the right side frame assembly 11 are different, and the first guard plate 2010 and the second guard plate 2011 do not need to be folded and do not need to be completely disassembled, and the legs do not need to be disassembled. The rest is the same and will not be repeated here.

[0082] Specifically, since the buckle structure 21 is rotatably assembled with the front pipe 120 of the left side frame assembly 10 and the right side frame assembly 11 through the sheet sliding layer, the left side frame assembly 10 and the right side frame assembly 11 can be folded and stored with one side of the front guard plate 201 in the same direction, and the first guard plate 2010 and the second guard plate 2011 are kept in the unfolded state and placed in the storage area 16 of the left side frame assembly 10 and the right side frame assembly 11. The sheet sliding layer used in the assembly of the buckle structure and the front pipe 120 in the embodiment of the present application can be selected as a Teflon sheet. In this way, the assembly gap between the buckle structure 21 and the front pipe 120 is filled with the Teflon sheet, and the Teflon sheet has a relatively smooth surface, so that the buckle structure 21 and the front pipe 120 can rotate without being disassembled after assembly. The folding and storage method of the embodiment of the present application can keep the overall width of the left side frame assembly 10 and the right side frame assembly 11 unchanged after folding, and the folding thickness is twice the thickness of the side pipe of the walker.

[0083] Therefore, the folding and storage method of the embodiment of the present application is suitable for vertical stacking with limited height and horizontal placement in a wide transportation space.

[0084] Third embodiment

[0085] As shown in Figure 10 , the difference between the embodiment of the present application and the first embodiment is that the folding and storage methods of the left side frame assembly 10 and the right side frame assembly 11 are different, and the legs do not need to be disassembled. The rest is the same and will not be repeated here.

[0086] Specifically, by unlocking the locking structure 30 on the front guard plate 201, then the second guard plate 2011 is folded by the hinge end 2012 with the first guard plate 2010, and then the left side frame assembly 10 and the right side frame assembly 11 are centered and stored at the hinge end 2012 of the first guard plate 2010 and the second guard plate 2011. The folded front guard assembly 20 can be located in the storage area 16.

[0087] Using the folding storage method of the embodiment of the application, the overall width of the left side frame assembly 10 and the right side frame assembly 11 after folding can be reduced by one fifth, and the folding thickness is 2 times the thickness of the side tube of the walker. Therefore, the folding storage method of the embodiment of the application is especially suitable for transportation space with limited vertical stacking height and more spacious horizontal placement.

[0088] Fourth embodiment

[0089] As Figures 11-13 the difference between the embodiment of the application and the first embodiment is that the front guard plate 201 is not foldable, that is, the first guard plate 2010 and the second guard plate 2011 are designed as an integral type, and the first guard plate 2010 and the second guard plate 2011 are not foldable.

[0090] In addition, as Figure 12 shown, as in the first embodiment, when the two ends of the left side frame assembly 10 and the right side frame assembly 11 are transposed and stored in the same horizontal plane, the front side foot 1202 of the left side frame assembly 10 and the right side frame assembly 11 is located in the storage area 16. The difference is that the non-foldable front guard plate 201 is placed on the surface of the left side frame assembly 10 and the right side frame assembly 11, but the two ends of the front guard plate 201 and the buckling structure 21 thereof can still be stored in the storage area 16. As Figure 13 shown, as in the folding storage method of the second embodiment. The remaining parts are the same, and will not be repeated here.

[0091] The above embodiments are only preferred embodiments of the application, and cannot be used to limit the scope of protection of the application. Any non-essential changes and substitutions made by those skilled in the art based on the application are within the scope of protection of the application.
