[0014] 1. The vertical direction is initially positioned by the guide plate. When it enters the support platform and reaches a fixed position, it is positioned by the positioning structure. The manual grabbing hand crank is shaken to drive the cam to rotate. When the groove of the cam rotates to the bottom of the roller, it is inserted into the groove. At this time, under the influence of its own weight, the lifting bracket descends, driving the support platform and the water tank to descend, while the front end is tilted to hold the water tank to prevent it from falling off;

[0015] 2. The cam mechanism is designed according to mechanics and can pull up a 600kg water tank with a force of 7kg. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4 The utility model provides a technical solution: a manual water tank roller trolley, comprising: a body 1, a pulley and a support platform are installed under the body 1, the body 1 is moved smoothly by the pulley, the front end of the body 1 is lowered, the support platform is in contact with the ground, and the body 1 is supported and anti-slip;

[0023] A rear baffle 11 is fixedly mounted on one side of the upper portion of the vehicle body 1, and the rear baffle 11 is used for abutting against the water tank;

[0024] A pair of push-pull handles 12 are installed on the surface of the rear guard frame 11, and the push-pull handles 12 are used to push and pull the vehicle body 1;
