Description

It has the advantages of simple operation, flexible movement, and long working time.

[0003] However, when moving the new cart-type long-tube respirator, it is necessary to press down the upper push rod and use the rollers as a fulcrum to move it. The smooth movement of the new cart-type long-tube respirator depends on always keeping the support legs off the ground. In actual use, the up and down shaking of the pusher's hand will cause the new cart-type long-tube respirator to swing up and down as a whole, and the up and down swinging of the new cart-type long-tube respirator will cause the support legs to contact the ground. When the support legs contact the ground, reverse resistance will occur, which will affect the movement of the new cart-type long-tube respirator. Similarly, after placing the new cart-type long-tube respirator, it is necessary to step on the brakes on the rollers on both sides to stabilize the new cart-type long-tube respirator. When the brakes are canceled, they need to be bent upwards, which is laborious to operate. Utility Model Content

A support leg 4 is extended from one end of the fixing frame 2 away from the roller 3, and the lower end of the support leg 4 is flush with the lower end of the roller 3. It also includes: an auxiliary rolling mechanism, the auxiliary rolling mechanism is arranged at the lower end of the fixing frame 2, the auxiliary rolling mechanism includes a push-pull rod 8, one end of the push-pull rod 8 is provided with an auxiliary wheel 6, the auxiliary wheel 6 is rotatably arranged on the support leg 4, the other end of the push-pull rod 8 is movably arranged on the fixing frame 2, and the auxiliary wheel 6 can be driven by the push-pull rod 8 to support the support leg 4 for overall movement; a stabilizing mechanism, the stabilizing mechanism is arranged on both sides of the push-pull rod 8, the stabilizing mechanism is matched with the roller 3, and can be The driving card is connected to both sides of the roller 3, thereby improving the overall stability; when the respirator needs to be moved to the position, the roller 3 is first used as a fulcrum to lift the support leg 4, and then the push-pull rod 8 is pulled backward. The push-pull rod 8 drives the auxiliary wheels 6 to be upright on both sides of the support leg 4. After the auxiliary wheels 6 are upright and in contact with the ground, they can be put down. At this time, the rollers 3 and the auxiliary wheels 6 are used as a rolling movement mode, which greatly improves the movement efficiency and does not need to press the bracket 1 forward all the time. When the position is reached, the support leg 4 is also pried up with the roller 3 as a fulcrum. After prying up, the push-pull rod 8 is pushed forward to drive the upright auxiliary wheels 6 backward. At this time, the push-pull rod 8 drives the stabilizing mechanism to be clamped on the roller 3 to limit and fix the roller 3 to prevent the roller 3 from rotating, and the support leg 4 contacts the ground to form a conflict, so that the whole can be stably placed on the ground.

[0024] like Figure 4 、 Figure 5 、 Figure 6 and Figure 7As shown: the auxiliary rolling mechanism also includes: a connecting member 5, the connecting member 5 is rotatably connected at both ends of the end of the support leg 4, the auxiliary wheel 6 is fixedly connected at the lower end of the connecting member 5, a cross bar 7 is fixedly connected between the inner sides of the connecting member 5, and the cross bar 7 is rotatably connected to the end of the push-pull rod 8; a fixed seat 9, the lower end of the fixed seat 9 is rotatably connected to a rotating member 10, the rotating member 10 is a waist-shaped hollow setting, and the two ends of the fixed sheath 11 can pass through the two ends of the rotating member 10, and the rotating member 10 is slidably connected with a fixed sheath 11, the fixed sheath 11 can slide up and down on the rotating member 10, and slide in conjunction with the movement of the push-pull rod 8, the fixed sheath 11 is fixed on the push-pull rod 8, and the outer end of the fixed seat 9 is fixedly connected It is connected to a connecting plate 14, which is provided with a first fixing hole 16 and a second fixing hole 15.
