Description

Technical Field

[0001] This utility model belongs to the field of walking aid technology, specifically relating to a parking limit device for a walking aid. Background Technology

[0002] A walking aid is a medical device that falls between a cane and a wheelchair, primarily used to assist with walking, temporary rest, and shopping. It provides support by being held by both hands, helping the user maintain balance and distribute some of their weight.

[0003] The existing walking aid braking system cannot limit the parking position during use, requiring the user to continuously press down to park, which makes the walking aid inconvenient to use, uncomfortable, and affects the convenience of using the walking aid. Utility Model Content

[0004] To address the problems mentioned in the background section, this invention provides a parking limit device for a mobility aid, which features stable and convenient parking.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a parking limit device for a walking aid, comprising a handlebar tube, a grip plastic seat body being snapped onto one side of the handlebar tube, a grip plastic seat cover being installed on the other side of the handlebar tube corresponding to the grip plastic seat body, a brake cable guide seat being fixed inside the handlebar tube, a brake cable guide wheel being movably connected inside the brake cable guide seat, a brake cable being provided on one side of the brake cable guide wheel, a positioning plug being connected to one end of the brake cable, a handle being movably connected inside the grip plastic seat body, an installation hole being provided on one side of the handle, a parking fixing spring being fixed inside the installation hole, a parking fixing component being connected to one end of the parking fixing spring, a parking unlock button being fixed on the surface of the grip plastic seat body corresponding to the parking fixing component, and a positioning opening being provided inside the grip plastic seat cover corresponding to the parking fixing component.

[0006] Preferably, a guide groove is provided on one side of the inner side of the handle plastic seat body corresponding to the handle, and a limit groove is provided on one side of the inner side of the handle plastic seat cover corresponding to the handle.

[0007] Preferably, the handle has a connecting groove inside corresponding to the positioning plug, and a notch is provided on one side of the connecting groove.

[0008] Preferably, the handle tube has a fixing hole inside corresponding to the brake cable guide seat and the brake cable guide wheel, and a fixing shaft is installed inside the fixing hole.

[0009] Preferably, a steel wire rope is connected between the positioning plug and the brake line, and the steel wire rope is supported by the brake line guide wheel and passes through the interior of the brake line guide seat.

[0010] Preferably, the surface of the parking unlock button has a protrusion corresponding to the parking fastener, and the interior of the handle plastic seat body has an installation groove corresponding to the parking unlock button.

[0011] Preferably, a grip sleeve is fitted and fixed to the surface of the handle tube, and the surface of the grip sleeve is provided with anti-slip texture.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention features a parking retainer and a parking spring installed inside the handle. The downward-moving handle can be moved, and the parking retainer engages with the positioning hole, slightly moving a protrusion to prevent the handle from automatically resetting. The brake cable then applies continuous traction to achieve automatic parking. Pressing the parking unlock button compresses the parking spring at the bottom of the parking retainer, pushing it back into the mounting hole. This allows the brake cable to reset the handle, ensuring convenient use and providing a limit on parking and quick, easy unlocking. Attached Figure Description

[0020] Specifically, a guide groove 17 is provided on one side of the inner side of the handle plastic seat body 2 corresponding to the handle 10, and a limit groove is provided on one side of the inner side of the handle plastic seat cover 4 corresponding to the handle 10.

[0021] By adopting the above technical solution, the handle 10 can move up and down stably without deviation, thus improving the quality of equipment use.

[0022] Specifically, the handle 10 has a connecting groove 12 inside corresponding to the positioning plug 14, and a notch is provided on one side of the connecting groove 12.

[0023] By adopting the above technical solution, the handle 10 can easily pull the positioning block 14 to move when it moves, so as to realize the functions of braking and parking.

[0024] Specifically, the handlebar tube 3 has a fixing hole 16 inside corresponding to the brake cable guide seat 7 and the brake cable guide wheel 6, and a fixing shaft is installed inside the fixing hole 16.

[0025] By adopting the above technical solution, the brake cable guide seat 7 and the brake cable guide wheel 6 are installed stably, thereby improving the traction stability of the brake cable 5.

[0026] Specifically, a steel wire rope is connected between the positioning plug 14 and the brake line 5. The steel wire rope is supported by the brake line guide wheel 6 and passes through the interior of the brake line guide seat 7.

[0027] By adopting the above technical solution, the traction strength of the brake line 5 is guaranteed, and the quality of use of the walking aid is improved.

[0028] Specifically, the surface of the parking unlock button 1 is fixed with a protrusion 18 corresponding to the parking fastener 8, and the inside of the handle plastic seat body 2 is provided with an installation groove corresponding to the parking unlock button 1.

[0029] By adopting the above technical solution, the protrusion 18 can accurately and stably push the parking fastener 8, ensuring the quality of use.

[0030] Specifically, a grip sleeve 13 is fitted and fixed to the surface of the handle tube 3, and the surface of the grip sleeve 13 is provided with anti-slip texture.

[0031] By adopting the above technical solutions, the stability of the walking aid is improved during use, and the comfort of the user holding the handlebar tube 3 is guaranteed.

[0032] The working principle and usage process of this utility model: When using this utility model, if parking is required during the use of the walking aid, press down on the handle 10 so that it moves down along the guide groove 17 and the limiting groove inside the handle plastic seat cover 4. At this time, the parking fixing part 8 inside the handle 10 moves accordingly. When the parking fixing part 8 corresponds to the positioning port 15, the compressed parking fixing spring 9 resets and pushes the parking fixing part 8 out of the mounting hole 11. The parking fixing part 8 is inserted into the positioning port 15 and pushes the protrusion 18 to move slightly. At this time, the parking fixing part 8 is stuck in the positioning port 15 to prevent the handle 10 from automatically resetting.

[0033] As the handle 10 moves down, the positioning block 14 inside the connecting groove 12 is forced to move along the brake line guide wheel 6. The positioning block 14 pulls the brake line 5 to move, so that the scooter completes the parking operation. At the same time, because the parking fastener 8 is stuck in the positioning port 15, the handle 10 cannot be reset, and the brake line 5 continues to be pulled to achieve the automatic parking function.

[0034] When the parking state needs to be unlocked, pressing one end of the parking unlock button 1 causes the protrusion 18 to push the parking fixing spring 9 at the bottom of the parking fixing part 8 to compress, pushing the parking fixing part 8 back into the mounting hole 11. At this time, the brake cable 5 can be released. The released brake cable 5 pulls the positioning plug 14 and drives the handle 10 to move upward and reset along the inside of the handle plastic seat body 2, ensuring the convenience of using the equipment and realizing the functions of parking limit and easy and quick unlocking.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
