Background technique

A new study published in the British "Lancet Global Health" predicts that if the treatment of eye diseases is not strengthened, the number of blind people in the world will increase to 115 million by 2050, which is 2.2 times more than the current 36 million. The proportion of visually impaired people is actually declining, but the number will soar over the next few decades as the global population and older populations increase, the report said. In addition to the blind population, there are more than 200 million people in the world with moderate or severe vision impairment, and this number is estimated to increase to more than 550 million by 2050.

As the most populous country in the world and one of the countries with the most blind people in the world, eye disease is also a major public health problem in China. There are about 6-7 million blind people in China, accounting for 18% of the total blind people in the world, and another 12 million people with low vision in both eyes. At the same time, 450,000 blind people are newly added in my country every year. The blind stick is a very useful behavioral aid for them.

Defects of traditional blind sticks: Traditional blind sticks cannot fully adapt to the current complex road conditions. With the popularization of blind roads, blind roads have played an increasingly important role for the blind to travel, but traditional blind sticks cannot correctly find the blind road. , the traditional directional walking method and the limitations of the traditional blind stick can no longer meet the needs of the blind people to travel in the new era.

Detailed ways

In order to make the objectives, technical solutions and advantages of the present invention more clear, the technical solutions of the present invention will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other implementations obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present invention.

Referring to Figures 1-2, the present utility model provides a self-positioning alarm and rescue multifunctional blind stick, comprising a foldable rod body 1, the upper end of the rod body 1 is sleeved with a handle 9, and the lower end of the rod body 1 is rotatable A rotating bracket 3 is installed on the swivel bracket 3, and three connecting frames 4 evenly distributed around the center of the rotating bracket 3 are fixedly installed on the outer wall of the rotating bracket 3, and casters 5 are installed at the lower end of each connecting frame 4;

The rotating bracket 3 includes a sleeve 302 and an end cover 301 fixedly connected to the lower end of the sleeve 302. The sleeve 302 is installed at the lower end of the rod body 1 through a bearing, and the center of the upper surface of the end cover 301 is fixedly connected. The upper end extends into the cavity of the rod body 1, and a plurality of protrusions 12 arranged at equal intervals are arranged on the upper surface of the column 13. The shortest distance between the adjacent two protrusions 12 is equal, and the lower end cavity of the rod body 1 is provided. A mounting bracket 14 is fixedly arranged on the side wall of the mounting bracket 14, the end of the mounting bracket 14 is hinged with a limit piece 11, and a circlip (not shown in the figure) is installed on the position where the limit piece 11 is hinged with the mounting bracket 14, and the circlip In the free state, as shown in FIG. 2 , the right end of the limiting piece 11 is always driven to press down, and one end of the limiting piece 11 close to the mounting frame 14 is connected with a pull rope 10 for driving the limiting piece 11 to rotate.

As an optional embodiment, the side of the handle 9 is provided with a through hole penetrating the side wall of the rod body 1 and the side wall of the handle 9 , and a braking pull ring 6 is installed at the outer position of the through hole. The inner pull rope 10 is connected, and the diameter of the brake pull ring 6 is larger than the diameter of the through hole. Under normal conditions, the brake pull ring 6 is close to the outer side wall of the handle 9. When the rotating bracket 3 needs to be positioned, the brake pull ring 6 can be pulled. Move the pull ring 6 to realize the rotation of the limiting piece 11 .

The upper end of the rod body 1 is fixedly installed with an SOS alarm (not shown in the figure), and the handle 9 is inlaid with an SOS alarm button 7 for controlling the work of the SOS alarm to send an alarm signal through the SOS alarm button 7 with one key. ,Convenient.

The handle 9 is made of rubber material, and the upper end of the handle 9 is connected with a wrist ring 8 to be connected to the wrist of the blind person to prevent the blind stick from falling off.

The thickness of the limiting piece 11 is equal to the distance between the two connected protrusions 12, so the setting is so that after the left end of the limiting piece 11 moves down, it can smoothly enter the gap between the two protrusions 12, which is convenient and reliable. .

The rod body 1 includes a plurality of short rods, and two adjacent short rods are sleeved and connected to each other. This arrangement is to facilitate the carrying of the blind stick and to reduce the footprint.

Reflective stickers 2 are adhered to the outer wall of the short bar located in the penultimate section below, which can facilitate reflection at night and improve the safety of blind people traveling at night.

A GPS locator (not shown in the figure) is installed in the inner cavity of the upper end of the rod body 1, and the GPS locator is connected to the mobile phone of the blind family member through a wireless signal, so that the family member can quickly find the blind person.

By adopting the above-mentioned self-positioning alarm and rescue type multifunctional blind stick, the rod body 1 is in a folded state in a non-working state. The specific principle is that the two adjacent short rods are separated from each other. Connecting a plurality of short rods can prevent one or more of the short rods from being lost; when in use, two adjacent rod bodies 1 are sleeved and assembled with each other, and the specific working method is as follows: two adjacent short rods In the connection position, the diameter of one short rod end is connected with the inner diameter of the other short rod end. After the assembly is completed, the blind person holds the handle 9, the caster 5 is in contact with the ground, and one of the casters 5 encounters an obstacle. When it cannot continue to roll, the rotating bracket 3 can rotate around the rod body 1, which is convenient for the blind to adjust the direction in time; when the blind stick is not used, the operator can pull the brake pull ring 6 at the position of the handle 9, and the brake pull ring 6 drives the The pull rope 10 moves upward, thereby driving the limit piece 11 to overcome the force of the circlip, so that the left end of the limit piece 11 moves downward. When the limit piece 11 moves to the gap between the two adjacent protrusions 12 above the column 13 At this time, the pulling rope 10 exposed above is wound and tied on the handle 9, at this time, the rotating bracket 3 and the rod body 1 are in a mutually stationary state, the rotating bracket 3 is no longer free to rotate, and the blind cane can be used as a blind person. When the rotating bracket 3 needs to be rotated again, loosen the pull rope 10 bound on the handle 9, and the limit piece 11 can lift the left end up under the force of the circlip and separate from the column 13 The upper protrusion 12 has a gap, at this time, the rotating bracket 3 can rotate freely again;

The SOS alarm installed in the inner cavity of the upper end of the rod body 1 can send an alarm signal under the action of the SOS alarm button 7. The SOS alarm is connected with the mobile phone of the user's family through a wireless signal, and can actively send an alarm when the blind person needs help. The GPS locator installed in the inner cavity of the rod body 1 is also connected to the family's mobile phone, and the family can check the position of the blind person in real time, which is easy to find.

The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited to this. Replacement should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
