Detailed Description

The present application is described in further detail below with reference to figures 1-7.

The application discloses calabash cloth cover of flexible water pipe, refer to fig. 1, flexible water pipe 1 overcoat is equipped with cloth cover 2 with flexible water pipe 1 synchronous telescope, and cloth cover 2 generally sets up to weave the cloth, weaves the cloth and can adopt nylon fiber, high-strength silk, wear-resisting yarn etc. to weave and form, and wherein, nylon fiber is because of characteristics such as its density is low, pliability is good, the hygroscopicity is strong, elasticity resilience is high, wearability and alkali resistance are good widely used.

The cloth cover 2 has the characteristics of axial and radial expansion, the cloth cover 2 comprises a plurality of corrugated units 3 which are connected in an end-to-end mode, and each corrugated unit 3 is respectively sleeved outside the telescopic water pipe 1 to form a layer of folds.

When flexible water pipe 1 is flexible, ripple unit 3 is followed flexible water pipe 1's axial and radial flexible on the cloth cover 2, then cloth cover 2 can together stretch out and draw back with flexible water pipe 1, but again because the flexible volume of cloth cover 2 receives the restriction of cloth and ripple unit 3 diameter, can restrict flexible water pipe 1's flexible, avoids flexible water pipe 1 to lead to the emergence of the water pipe scheduling problem that breaks because of reasons such as water pressure is too big. Namely, the cloth sleeve 2 plays a role in protecting the telescopic water pipe 1, and the cloth sleeve 2 is wound on the periphery of the telescopic water pipe 1, so that the exposure of the outer surface of the telescopic water pipe 1 is prevented, and the probability of friction damage of the telescopic water pipe 1 is reduced; but also can restrict the expansion of the telescopic water pipe 1 and prevent the telescopic water pipe 1 from being excessively stretched.

Referring to fig. 2, the corrugated unit 3 is provided with an inner concave portion 31 and a convex portion 32, the inner concave portion 31 and the convex portion 32 are arranged along the axial direction of the corrugated unit 3, and the inner concave portion 31 and the convex portion 32 are alternately arranged to form a bending shape, when the cloth cover 2 is elongated, the convex portion 32 and the inner concave portion 31 are simultaneously elongated and unfolded, so that the amount of expansion and contraction of the cloth cover 2 in the axial direction is increased.

The concave portions 31 of adjacent corrugated units 3 face the same end of the cloth cover 2, and the convex portions 32 of adjacent corrugated units 3 face the same end of the cloth cover 2. Referring to fig. 3, when the cloth cover 2 is in the contracted state, the concave portions 31 of adjacent corrugated units 3 are partially nested, and the convex portions 32 of adjacent corrugated units 3 are partially nested, that is, the concave portions 31 of adjacent corrugated units 3 are contracted toward the same side, so that the concave portion 31 at the front end is contracted into the concave portion 31 at the rear end, and the convex portion 32 at the front end is contracted into the convex portion 32 at the rear end. The occupied space of the cloth cover 2 is reduced, namely, the cloth cover 2 with the same length is adopted, and the larger axial expansion amount can be achieved.

Referring to fig. 4, one side of each of the corrugated units 3 is provided with an outer convex surface 33, and the other side is provided with an inner concave surface 34, so that when the cloth cover 2 is in a contracted state, the outer convex surface 33 of the front corrugated unit 3 is sleeved in the inner concave surface 34 of the rear corrugated unit 3 in the two connected corrugated units 3. When the corrugated units 3 are in the contracted state, the adjacent corrugated units 3 can be in a stacked state, so that the cloth cover 2 has larger axial expansion and contraction amount when the corrugated units 3 are unfolded.

The first embodiment is as follows:

referring to fig. 5, the concave portions 31 and the convex portions 32 are provided at the peak positions of the corrugated unit 3, that is, when the cloth cover 2 is stretched, the concave portions 31 and the convex portions 32 at the peak positions are simultaneously expanded, increasing the amount of expansion and contraction in the axial direction of the cloth cover 2.

The outer side surface of the cloth cover 2 is provided with a wear-resistant protective layer 4, the wear-resistant protective layer 4 is made of elastic plastic materials or elastic leather products, the wear-resistant layer is pasted on the outer surface of the cloth cover 2 through viscose, and the wear-resistant protective layer 4 can be coated on the outer surface of the cloth cover 2 to protect the whole cloth cover 2.

Wear-resisting protective layer 4 also can set up in the crest position department of ripple unit 3, because the cloth cover 2 of crest position department receives external friction when flexible big than other positions, and wearing and tearing are more serious, and wear-resisting protective layer 4 sets up can reduce the wearing and tearing of cloth cover 2 when flexible in crest position department, prolongs the life of cloth cover 2, and saves the cost of the 4 materials of wear-resisting protective layer and the cost of processing. Can protect the surface of the cloth cover 2, lead the cloth cover 2 not to be easily worn directly in the dragging process, and prolong the service life of the cloth cover 2.

The inner side of the cloth cover 2 is provided with a protective film 5, the protective film 5 is made of PE plastic films, the protective film 5 has elasticity, the protective film 5 is fixed on the inner side of the cloth cover 2 in a viscose mode, friction between the cloth cover 2 and the outer surface of the telescopic water pipe 1 can be reduced, the telescopic water pipe 1 is protected, and the service life of the telescopic water pipe 1 is prolonged.

The protective film 5 can cover the inner side of the whole cloth cover 2 and can also be arranged at the positions of wave troughs of the corrugated units 3. When flexible water pipe 1 and cloth cover 2 are stretched, the easy and wave trough position contact of ripple unit 3 of flexible water pipe 1 lateral surface leads to weaving the flexible water pipe 1 of cloth cover 2 friction that forms, causes wearing and tearing to flexible water pipe 1 lateral surface, reduces flexible water pipe 1's life. When the wave trough position of the corrugated unit 3 is pasted or coated with the protective film 5, the friction between the telescopic water pipe 1 and the cloth sleeve 2 is reduced, and the telescopic water pipe 1 is protected.

The implementation principle of the calabash cloth cover of the telescopic water pipe in the embodiment of the application is as follows: when the telescopic water pipe 1 is introduced with pressure water to stretch, the cloth cover 2 can stretch along with the stretching of the telescopic water pipe 1 due to the folds of the cloth cover 2, and meanwhile, the convex part 32 and the inner concave part 31 are stretched and unfolded, so that the cloth cover 2 and the telescopic water pipe 1 can stretch axially and radially together.

Example two:

referring to fig. 6, the difference from the first embodiment is that: the concave portions 31 and the convex portions 32 are provided between the peaks and the valleys of the corrugated unit 3. When the cloth cover 2 is stretched, friction between the concave portion 31 and the convex portion 32 can be reduced, and the service life of the concave portion 31 and the convex portion 32 can be prolonged.

Example three:

referring to fig. 7, the difference from the first embodiment is that: the concave portions 31 and the convex portions 32 are provided at the valley positions of the corrugated unit 3. When the cloth cover 2 is stretched, friction between the concave portion 31 and the convex portion 32 can be reduced, and the service life of the concave portion 31 and the convex portion 32 can be prolonged.

The concave part 31 and the convex part 32 can also be extended to the wave trough position of the ripple unit 3 by the wave crest of the ripple unit 3, so that the whole ripple unit 3 is in a bending state, and the axial expansion amount of the cloth cover 2 is greatly improved.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
