The upper bracket 1 includes an embracing protection rod 11, a chest rest 12, a main support frame 13 and an elderly handle 14; the main support frame 13 is formed by bending several pipes, and the front end of the main support frame 13 is a back-shaped nurse handle, and the rear The end is a chest rest bracket, which is connected by a connecting pipe between the back-shaped nurse handle and the chest rest support; the lower end of the back-shaped nurse handle is connected to the pin hole on the slewing height adjustment rod 31 through a connecting rod, and between the connecting rod and the pin hole It is fixed by the ball head locking pin, and the height adjustment is realized by the combination of pin holes in different positions; the middle of the connecting rod at the lower end of the back-shaped nurse handle is provided with an elderly handle 14; There is an embracing protection rod, each embracing protection rod is composed of two parts of elbows, the two parts of the elbows are sleeved together, and the two parts of the elbows can rotate relative to each other; It can be used for the elderly to lean back when sitting on the truck, and at the same time, it can prevent the elderly from falling backward during the transportation, so as to play a protective and support role; It is made of material and is located at the end of the embracing protection rod 11. It is the main support part of the body during the lifting of the elderly. The soft sponge ensures the comfort of the elderly during the lifting process; the elderly handle 14 is fixed on the main support. The middle and lower parts of the frame are used for grasping when the elderly are lifted, and share part of the gravity when the elderly are lifted, increasing the comfort and safety of the handling process;

The present invention is further characterized in that the pipe material and the bent pipe are both aluminum alloy pipes, which are simple and lightweight.

In the present invention, the right pedal 411 and the left pedal 412 are both fixed at the left and right positions of the front end of the foot pedal for the elderly through corresponding fixed shafts. The length of the right pedal link 46 and the left pedal link 47 are different, and the right pedal link 46 is longer Short, the left pedal link 47 is longer, the rear end of the right pedal 411 is connected with the front end of the right pedal link 46; the middle part of the left pedal 412 is connected with the front end of the left pedal link 47, and the right pedal 411 and the left pedal 412 are on the right The pedal link 46 and the left pedal link 47 are driven to rotate around their respective fixed axes; the working states of the left and right pedals are opposite. The pedal link 47 pushes the first push rod 48 forward, and drives the third push rod 40 to rotate through the second push rod 49, thereby increasing the angle between the splayed legs. The movement drives the right pedal link 46 to stretch forward, so that the right pedal 411 rotates around the fixed axis, and its rotation direction is opposite to that of the left pedal 412, the right pedal is in a raised state, and the left pedal is in a depressed state; this is because the left pedal 412 The connection positions of the right pedal 411 and the corresponding link are different (as shown in FIG. 4 ) and the lengths of the right pedal link 46 and the left pedal link 47 (the right pedal link 46 is shorter and the left pedal link 47 is longer). ) determined (that is, different rod lengths determine different motion states); in the same way, stepping on the raised right pedal 411 can make the angle between the eight-shaped legs smaller, while the left pedal 412 is lifted; the purpose of making the angle larger It is to lower the center of gravity of the truck and increase the stability and safety of the truck during the process of lifting the elderly. After the elderly sit firmly, adjust the angle to facilitate movement.

A further feature of the present invention is that the truck is further provided with a casing 5 (see FIG. 6 ), the casing wraps the middle bracket 3 , the swing height adjustment rod 31 , the connecting rod 32 , the load-bearing rod 33 , the footrests 34 and the feet of the guards The pedal locking mechanism 35 is all wrapped in the casing 5, which makes the overall appearance more beautiful. The upper part of the casing 5 is provided with an opening that can expose the upper end of the middle bracket 3 , the middle part is provided with a through hole through which the seat cushion support rod 22 can be inserted, and the front end of the bottom is provided with a hole for exposing the footrest 34 of the guard.

There is a row of pin holes on the slewing height adjustment rod of the truck of the present invention, which can be connected with the pin holes on the main support frame 13 through pins to realize height adjustment to adapt to the height difference of the elderly; The lifting and lowering actions of the old man; in the process of lifting the old man up, the foot pedal 34 of the nurse can be locked by the foot pedal locking mechanism 35, and the function of locking is to keep the old man in the lifted state. When the nurse can move to the middle of the truck and rotate the seat cushion 21 to a horizontal position for the elderly to sit down, then the nurse can step on the foot pedal again to release the locked state and place the elderly on the cushion to sit firmly.

The front and rear orientation words in the present invention are relative concepts. In this application, the side where the back-shaped nurse handle is located is defined as the front, and the side where the chest rest is located is the rear.

What is not described in the present invention applies to known techniques.
