Gear holes are opened on the first bracket and the second bracket.

The inner sides of the first bracket and the second bracket are respectively provided with concave slide grooves; the outer surfaces of the second bracket and the third bracket are respectively provided with convex slide grooves; and the concave slide grooves on the first bracket are connected with the The convex chute on the second support is used in conjunction with the concave chute on the second support and the convex chute on the third support is used in conjunction.

LED lights and switches connected thereto are installed on the side of the arm support.

Rubber foot pads are installed on the bottoms of the second bracket and the third bracket.

The second bracket is provided with an upper strap hole; the third bracket is provided with a lower strap hole.

A bench is installed on the second support.

The gear adjustment button includes a button housing, and a spring strut is installed inside, a spring is installed at one end of the spring strut, and a button is installed at the other end of the spring.

The buttons are arranged in a square shape.

The buttons are arranged in a square shape.

The beneficial effects of the utility model are: the utility model is aimed at the disadvantages of the traditional underarm crutches such as single function, inconvenient carrying, and the inability to control the position and angle of a single button. It is used in conjunction with a spring to form a retractable button, and by using the square design of the button shape and the elastic effect of the spring, on the one hand, it can realize the functions of a cylindrical button, and on the other hand, it can control the position and angle according to the needs. For some folding mechanisms and supporting mechanisms, it can simplify and save costs. The more important point is that the utility model realizes the height adjustment and folding of the crutches in different ways, thereby realizing the function of folding and transforming into a stool; the combination of the chute can strengthen the stability of the crutches, and it is easy to use and install. The strap design and lighting design provide convenience for the user's life.

Detailed ways

Example 1

As shown in Figure 1-4, a new type of multifunctional foldable armpit crutch comprises a first support 1, a second support 2 and a third support 3; One end is fixedly installed with a handshake 6; wherein the first bracket 1 and the handshake 6, and the second bracket 2 and the third bracket 3 are respectively movably connected by gear adjustment buttons 4. The first bracket 1 and the second bracket 2 are provided with shift holes 7 . The first bracket 1 and the second bracket 2 are respectively provided with a concave slide groove 8 on the inner side; the second bracket 2 and the third bracket 3 are respectively provided with a convex slide groove 9 on the outer surface; and the first bracket The concave chute 8 on the 1 is used in conjunction with the convex chute 9 on the second bracket, and the concave chute 8 on the second bracket 2 is used in conjunction with the convex chute 9 on the third bracket 3 . An LED lamp 10 and a switch 11 connected thereto are installed on the side of the arm support 5 . Rubber foot pads 12 are installed on the bottoms of the second bracket 2 and the third bracket 3 . The second bracket 2 is provided with an upper strap hole 13 ; the third bracket 3 is provided with a lower strap hole 14 . The gear adjustment button includes a button housing 1, and a spring strut 2 is installed inside, a spring 3 is installed at one end of the spring strut 2, and a button 4 is installed at the other end of the spring 3. The buttons 4 are arranged in a square shape. When the position and angle need to be adjusted, press the button 4, due to the elasticity of the spring 3, the button is retracted into the button shell, at this time, rotate to a suitable position, release the button, and reset it, so that the desired position can be locked. Position, simple and convenient operation, especially suitable for folding mechanism. A gear adjustment button in this embodiment realizes the integration of position adjustment and position angle control, and the shape of the square button can realize the simple conversion of 90 degrees and 180 degrees at the matching position, which greatly simplifies the number of parts of the folding mechanism that realizes the same function and saves Cost; and good stability, easy to use and install.

When in use, the functional foldable armpit crutch is in the state of using the crutch while walking, as shown in Figure 3. When the user is riding in a car, having a meal or going to a theater to watch a movie, the crutch can be folded, shrunk into a smaller volume and placed on the Next to it, it will not get in the way of others and is very space-saving. The specific operation method is: through the gear position adjustment button 4, the gear position adjustment button 4 is hollowed out inside and used in conjunction with the spring to form a retractable button to adjust the gear position at the connection between the third bracket 3 and the second bracket 2 Press the button 4 inwards, turn the third bracket 3 180° opposite to each other, then the third bracket 3 can be folded into the second bracket 2; turn the gear adjustment button 4 at the connection between the handshake 6 and the first bracket 1 inward Press, turn the second bracket 2 together with the third bracket folded into it by 90°, that is, the second bracket 2 and the first bracket 1 can be received together into the first bracket.

When it needs to be used, it can also be unfolded by the gear adjustment button 4 voluntarily. And when unfolding as a crutch, the gear hole 7 on the second bracket 2 and the gear adjustment button 4 on the handshake 6, and the gear hole 7 on the third bracket 3 and the gear adjustment button 4 are used in conjunction ; When adjusted to a suitable height, release the gear adjustment button 4 so that it is just stuck on the corresponding gear hole to complete the unfolding of the crutches, as shown in Figure 1.

When the user uses crutches to travel, he can also adjust the handle to a designated position through the gear adjustment button 4 to make it a chair. The principle is the same as when folding; 13 acts as a chair surface. Turn the crutch into a chair. The user can take a short rest to relieve fatigue.

The strap design of this embodiment is a very difficult task for people who rely on crutches to go up and down the stairs. Said to increase the difficulty. The role of the strap is reflected here. When going up and down the stairs, a crutch is carried on the back, which avoids the danger of going up and down the stairs with a crutch. As for the design of the lighting components, when going out at night, the product of this embodiment can directly use the built-in LED lights at the armrests, and the angle can be adjusted to expand the lighting range. This does not need to free up one hand to use the lighting tool as before; it provides convenience for the life of the user.
