Detailed Description

The operator first takes out the hose car with the pipeline wound in advance, installs the tool box, holds the plastic hose sleeved outside the metal handle by the air blowing method in advance, presses the button 34 with both hands, rotates the connecting piece, namely the adjustable handle to a proper position, then pushes the hose car to a place to be visited, connects the water source pipe with the quick connector K10, and pulls out the pipeline distribution nozzle of the hose car to operate. These are convenient for the operator because of improvements in the axial clutch adjustment mechanisms of the rotatable connectors, such as integral gear rings and gears, as well as the accompanying tool boxes and quick-connects. Because the multifunctional novel garden hose car is composed of the blind rivet 1, the self-tapping screw 2, the fastening nut 3, the left fixing bracket 4, the elbow pipe 5, the sealing ring 6, the inner clamping joint 7, the water stop ring 8, the EPDM sealing ring 9, the European tooth female joint 10, the foot pipe fixing plate 11, the base 12, the wheel cover 13, the wheel buckle 14, the wheel 15, the electroplated wheel shaft 16, the lower bracket 17, the axle sleeve 18, the fixing frame 19, the wheel disc 20, the rocker seat 21, the positioner 22, the rocker sleeve 23, the handle buckle 24, the handle cover 25, the rocker 26, the right fixing bracket 27, the tool box 28, the tool box bracket 29, the metal handle 30, the plastic hose 31, the upper conjoined gear ring 33 of the rotary connecting piece, the gear 32, the lower conjoined gear ring 35, the key 34, and the quick joint K10, the wheel cover 13, the wheel buckle 14, the wheel 15, the electroplated wheel shaft 16, the lower bracket 17, the axle sleeves 18 together form the chassis and the running mechanism of the hose car, so that the wheels rotate when being pulled to enable the car to run. Since the plastic hose 31 is sleeved outside the metal handle 30, the hand feeling is good and the appearance of the hose car is beautiful. The plastic hose 31 is processed from expanded plastic using an extruder, for example from PVC, but preferably from EVA. The sleeving method cannot be tried by using a plurality of methods of a mechanical hard sleeve, but the method is also used for reducing the cost by using an air blowing method; the air pressure is adjusted to 4-6, preferably 5, by using a thin air gun head, namely the air gun head which is commonly used in workshops or specially made thinner; the plastic hose is stretched into the gap between the outside of the metal handle 30 and the plastic hose 31 sleeved on the handle, and is blown and conveyed at the same time, and the operation can be carried out after several minutes of training. Some hose car styles do not adorn the rotary type connecting piece, as the improvement, some hose cars are equipped with the rotary type connecting piece, some hose car hand (hold) 30 outsides do not overlap, some hose car cover are equipped with the plastic hose 31 of hand (hold), some hose cars do not have the toolbox, and some hose cars have the toolbox 28, some hose cars do not have quick-operation joint, and some hose cars have quick-operation joint K10, especially the scheme of quick buckle has been added, so install additional collocation and make the style many, give the multiple selection of customer, the multiple style of hose car has objectively been increased, the product way of selling has been exploited.
