Embodiment 1

[0049] like figure 1 and figure 2 As shown, this embodiment provides a stretchable and inflatable garden telescopic water pipe in a specific embodiment, which includes an elastic inner pipe 1 and a protective jacket 2, and the protective jacket 2 is sleeved on the outside of the elastic inner pipe 1 to form an inner and outer double pipe structure (In this embodiment, the unfolded length of the protective jacket 2 is greater than the length of the elastic inner tube 1 before stretching, and the protective jacket 2 is sleeved on the elastic inner tube 1 to form folds, such as figure 1 , of course, in other embodiments, the length of the protective jacket 2 after unfolding can also be equal to the length of the elastic inner tube 1 before stretching, and the protective jacket 2 also has stretchable elasticity), the elastic inner tube 1 and the two ends of the protective jacket 2 Simultaneously connect the valve connecting device (such as a water pipe joint, not shown in the fi...

Embodiment 2

[0058] like Figure 8 As shown, in this embodiment, the first gas charging port 7 and the external source gas source 10 used in the first embodiment are further improved: the first gas charging port 7 is provided with an internal thread 11 and a steel needle 12, and the steel needle 12 The needle 12 is provided with an air inlet, the steel needle 12 is hollow, and the air inlet communicates with the hollow area of ​​the steel needle 12 and the hollow box 4 .

[0059] In order to be easy to carry, it is sold as a set with telescopic water pipes, and to reduce costs, the external gas source 10 used in this embodiment is a portable small gas cylinder or a micro gas cylinder. When using a portable small gas cylinder or a micro gas cylinder as an external gas source, The principle of inflating is: since the portable small gas bottle or tiny gas bottle is provided with an external thread, directly screw the external thread on the portable small gas bottle or the small gas bottle wit...

Embodiment 3

[0062] like figure 1 , figure 2 , Figure 10 , Figure 11 , Figure 12 and Figure 13 As shown, this embodiment provides another kind of flexible and inflatable garden telescopic water pipe in a specific embodiment, which includes an elastic inner pipe 1 and a protective jacket 2, and the protective jacket 2 is sleeved on the outside of the elastic inner pipe 1 to form an inner and outer double pipe Structure (in this embodiment, the length of the protective coat 2 after unfolding is greater than the length before the stretching of the elastic inner tube 1, and the protective coat 2 is sleeved on the elastic inner tube 1 to form folds, such as figure 1 , of course, in other embodiments, the length of the protective jacket 2 after unfolding can also be equal to the length of the elastic inner tube 1 before stretching, and the protective jacket 2 also has stretchable elasticity), the elastic inner tube 1 and the two ends of the protective jacket 2 Simultaneously connect th...

Abstract

The invention discloses a telescopic water pipe with an air inflation device. The telescopic water pipe comprises an elastic inner pipe and a protection outer sleeve. The elastic inner pipe is sleevedand connected with the protection outer sleeve, and an inner-outer dual pipe structure is formed. An airtight space is formed between the elastic inner pipe and the protection outer sleeve. The telescopic water pipe is provided with the air inflation device. The air inflation device is used for inflating air to the airtight space. Since the elastic inner pipe is likely to be damaged due to friction constantly produced between the elastic inner pipe and the protection outer sleeve, the service life of the telescopic water pipe is greatly shortened. According to the main design thought, the telescopic water pipe is provided with the air inflation device, the air inflation device can inflate air into the airtight space, the elastic inner pipe and the protection outer sleeve make no contact in the using process of the air-inflated telescopic water pipe, accordingly, constant telescopic friction between the elastic inner pipe and the protection outer sleeve is avoided, friction force between the elastic inner pipe and the protection outer sleeve is reduced to the minimum as far as possible, accordingly, thinning and damage of the elastic inner pipe are greatly avoided, and the servicelife of the telescopic water pipe is ensured and prolonged.

Description

technical field [0001] The invention relates to the technical field of flexible pipe fittings, and more specifically, relates to a telescopic water pipe provided with an inflatable device. Background technique [0002] The mainstream flexible pipe fittings on the market are telescopic and inflatable water pipes. The telescopic and inflatable water pipes are more suitable for places where water flow is required and where the water source is far away. It saves the production cost of pipe fittings, and the length becomes shorter after rebounding, which is convenient for storage; the general stretchable and inflatable water pipe is composed of an elastic inner pipe and a braided outer pipe sleeved outside the elastic inner pipe. The structure is generally that the elastic inner tube can be extended and expanded to a certain multiple of the original length under the action of water pressure, so that the water pipe can be extended; this type of water pipe is due to the continuous ...
