Problems solved by technology

However, there are still some problems. The main reason is that the hose currently used cannot be stretched, that is, a ten-meter-long hose can only be transported to a place ten meters away from the water source at work. The conveying distance is limited, if the length is very long, its storage, transportation and use are more troublesome, and it is easy to be entangled during storage

Embodiment Construction

[0018] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0019] Such as figure 1 As mentioned above, the present invention includes an inner tube 2 and an outer tube 4 sleeved outside the inner tube 2, and is characterized in that,

[0020] The inner tube 2 is provided with an elongation margin in its axial and / or radial direction, which can be released when the inner tube 2 is filled with water, and can be regenerated after the water-filled state is eliminated;

[0021] The outer tube 4 is used for the storage of the inner tube 2 when the remaining amount is not released, and the forced expansion of the inner tube 2 when the remaining amount is released. The expansion includes the axial and / or radially elongated and reversible or partially reversible.

[0022] As a further improvement of the present invention, the outer tube 4 is made of elastic mate...

Abstract

The invention discloses a telescopic pipe. The telescopic pipe comprises an inner pipe and an outer pipe which is connected to the exterior of inner pipe in a sleeving mode, and is characterized in that the inner pipe is provided with an elongated allowance in the axial and/or radial direction of the inner pipe, and the allowance can be released when the inner pipe is filled with water and regenerated after the water filling state is eliminated; the outer pipe is used for the receiving of the inner pipe in the condition that the allowance of the inner pipe is in a non-released state, and for the forced expansion when the allowance of the inner pipe is released, and the expansion includes the elongation of the axial and/or radial direction of the outer pipe and is reversible or partially reversible. The telescopic pipe is provided with the inner pipe and the outer pipe, the inner pipe can be lengthened in the axial direction, and the outer pipe can be stretched by elastic deformation inthe axial direction; and through the coordination of the outer pipe and the inner pipe, a smaller size can be achieved due to the existence of external pipe elastic force when the telescopic pipe isnot used, and when the telescopic pipe is in use, the elastic elongation of the outer pipe can be overcome under the action of water pressure to meet length requirements for corresponding use.

Description

technical field [0001] The invention relates to a telescopic tube. Background technique [0002] At present, the connecting water pipes used in car washing and garden watering are commonly used hoses, which can be folded for easy storage, are relatively light, and are very convenient for storage and transportation. But there are still some problems, mainly because the hoses currently used cannot be stretched, that is, a ten-meter-long hose can only be transported to a place ten meters away from the water source at work. The conveying distance is limited, and if the length is very long, it will be troublesome to store, transport and use, and it is easy to be entangled during storage. Contents of the invention [0003] The object of the present invention is to propose a water pipe that can be expanded and contracted. [0004] In order to solve the above problems, the invention provides: [0005] A telescopic tube, comprising an inner tube and an outer tube sleeved outside...
