A pipe body is provided with a pipe cavity, the pipe cavity is provided with a first movable pipe, the first movable pipe is provided with a first convex ring which is threadingly connected to the pipe cavity. A third movable tube is sleeved in the rightend of the first movable tube in a left-and-right stretching way, a second movable tube is sleeved outside the right end of the first movable tube in a left-and-right stretching way. The right end ofthe second movable tube is provided with a retaining ring, the third movable tube is provided with a second convex ring which abuts against the inner wall of the right end of the second movable tube.The first convex ring is provided with a first plug block, and the second convex ring is provided with a second plug block. The top of the pipe body is provided with a water inlet hole, the top of the pipe cavity is provided with a first water collecting tank which is internally provided with a first water collecting cavity, and the first water collecting cavity communicates with the water inlethole. The bottom in the pipe cavity is provided with a second water collecting tank which is internally provided with a second water collecting cavity, and the second water collecting cavity communicates with the first water collecting cavity through a connecting pipe. Two ports of the power cable protection sleeve pipe can be clamped for waterproofing, and water can be collected for heat dissipation.

The invention discloses a roof-mounted type hydraulic cylinder lifting mechanism for a damper of a light and medium truck. The mechanism comprises an outer protective cylinder body (4), an outer cylinder body (5), a moveable spherical hinge (7) and a piston rod (9), wherein an oil inlet and a sealing member are arranged on the outer cylinder body. The mechanism is characterized by further comprising a lower installation shaft (1), an upper installation shaft (3), a dirt receiving ring (6) and a reinforcing plate (2). Both ends of the lower installation shaft are connected with a frame, the reinforcing plate is welded in the middle of the lower installation shaft, the lower installation shaft is in fastened connection with the outer cylinder body through a screw thread, the upper installation shaft is welded with the outer protective cylinder body, both shaft ends of the upper installation shaft are connected with an automobile container, the moveable spherical hinge is welded on the upper part of the piston rod, the outer protective cylinder body is sleeved on the moveable spherical hinge, and the top of the piston rod is sleeved with a shock absorbing gasket and is fixed by a locking nut. According to the invention, the oil cylinder is automatically leveled in the using process and still maintained vertical to the automobile body, so that, the quality product is greatly improved, and the safety and the stability of the product are ensured.
