Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described further:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of lifting device in the utility model;
Fig. 3 is the top view of Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is elaborated.
As shown in Figure 1, the shoulder belt 2 that the utility model comprises inclusion 1 and is connected on inclusion, back-up block 3 is provided with below described shoulder belt, described back-up block one end is connected on inclusion and the other end is provided with arc support 301, the both sides of described inclusion are respectively equipped with lifting device, and described lifting device comprises the receiver 4 being fixed on inclusion both sides, and described receiver is provided with telescopic lifting arm 5, described lifting arm is collapsible to be accommodated in the inner chamber of receiver, and described lifting arm lower end is provided with universal wheel 6.Described receiver 4 is provided with between two lifting arms, 5, two lifting arms and is provided with cross bar 7.Student in the process of walking, can grip cross bar 7, promotes the stability of walking.
As shown in Figure 2, the body of rod of described lifting arm 5 is provided with several grooves 501 vertically arranged, described receiver 4 lower end is provided with block 502, described block is provided with the projection 5021 with groove fit near one end of lifting arm, spring 503 is provided with in described receiver, described spring one end is connected with receiver, and the other end of described spring is connected with block and spring applies to make projection embed the elastic force of groove to block.This structure enables lifting arm extension and contraction control length easily, adapts to the student of different height.
As shown in Figure 3, the cambered surface of described arc support 301 is to inclusion 1 curving, and described arc support two ends are respectively equipped with bandage 302, and the head end of described bandage is provided with interface 303.Fast arc support 301 can be fixed on the support that waist carries out attaching type by bandage 302 and interface, in the process of walking, waist and the upper part of the body keep plumbness, student can being corrected bend because bearing the school bag appearance of walking caused of bearing a heavy burden for a long time, being conducive to the healthy development of vertebra and bone.
