Detailed Description

The following describes the embodiments of the present utility model further with reference to the drawings. The description of these embodiments is provided to assist understanding of the present utility model, but is not intended to limit the present utility model. In addition, the technical features of the embodiments of the present utility model described below may be combined with each other as long as they do not collide with each other.

1-4, the safety protection scooter for automobile maintenance comprises a bottom plate 1 and a plurality of support rods 4 with damping effect in the vertical direction, wherein the support rods are slidably arranged at two ends of the bottom plate 1; the top of the supporting rod 4 is fixedly connected with a supporting plate 5; the top of the supporting plate 5 is fixedly connected with a containing frame 6 with an open top; an explosion-proof airbag 7 smaller in size than the accommodating frame 6 is placed in the accommodating frame 6.

Above-mentioned safety protection scooter for auto repair, when the automobile body drops suddenly, the automobile body is at first pressed on explosion-proof gasbag 7, and explosion-proof gasbag 7 is pressed and is warp, plays certain cushioning effect to the impact, then the impact is further through having damping effect's bracing piece 4 in vertical direction buffering. Through the mutual cooperation of explosion-proof air bag 7 and bracing piece 4, can improve the buffer capacity to the impact force, and realize soft contact through explosion-proof air bag 7, can effectively reduce the damage to the chassis, can both play better safety protection effect to human body and automobile body.

Specifically, two ends of the bottom plate 1 are provided with parallel T-shaped sliding grooves 2; a sliding block 3 is slidably arranged in the T-shaped chute 2; the top of the sliding block 3 is fixedly connected with the bottom of the supporting rod 4. The T-shaped chute 2 and the sliding block 3 can play a double role of guiding and limiting displacement in the vertical direction.

Specifically, the support rod 4 is a hydraulic damping rod. Compared with a spring telescopic rod, the hydraulic damping rod has better buffering capacity for resisting sudden large impact load.

Specifically, a plurality of triangular reinforcing plates are fixedly connected between the top side wall of the supporting rod 4 and the bottom of the supporting plate 5 along the axial direction.

Specifically, the outer walls of the two sides of the bottom plate 1 are fixedly connected with a [ -shaped supporting rod 8; the outer flanges of the tool placement frames 9 are slidably mounted on the support rods 8 and the base plate 1. The tool placement frame 9 is slidably mounted on the support rod 8, so that a worker can move the position of the tool placement frame 9 at any time according to needs, and overhaul work is convenient.

Specifically, in order to conveniently adjust the illumination angle, screw rods 10 are arranged on the outer wall threads on the two sides of the bottom plate 1; one end of the screw rod 10 is fixedly connected with a connecting block 11; the connecting block 11 is connected with one end of a clamping ring 13 for clamping a flashlight 14 through a hinge 12; the clamping ring 13 opens at an end remote from the connection block 11.
