Description

Technical Field

[0001] This utility model relates to the field of telescopic water pipe technology, specifically a high-temperature resistant, high-strength, multi-layer fabric sleeve pipe. Background Technology

[0002] Telescopic water pipes are usually made of TPU or rubber. They are easily scratched or worn when dragged for a long time, rubbed against the ground, or in contact with sharp objects. Usually, multiple layers of cloth sleeves are wrapped around the outside of the telescopic water pipe to form a non-woven barrier on the surface of the pipe, reducing direct friction between the water pipe and hard objects such as the ground, corners, and gravel, preventing the surface of the water pipe from cracking or leaking due to friction, and extending its service life.

[0003] During prolonged use and dragging, it is inevitable that the telescopic water hose will break and leak. Repairing the hose requires cutting off both the telescopic hose and the multiple layers of fabric sleeves. However, the fabric sleeves are usually simply fitted onto the outer wall of the telescopic hose without being secured. After cutting, the inner layer of the telescopic hose will quickly retract into the fabric sleeve and cannot be manually pulled out. The fabric sleeves must be cut again to pull out the telescopic hose for repair. This operation is cumbersome and will cause the fabric sleeves to become shorter, resulting in a mismatch between the telescopic hose's extension and contraction, which will eventually cause the fabric sleeves to break due to long-term pressure. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a high-temperature resistant, high-strength, multi-layered fabric sleeve, which solves the problems mentioned in the background art.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A high-temperature resistant and high-strength multi-layered fabric sleeve includes a multi-layered fabric sleeve fitted over a telescopic water pipe. The multi-layered fabric sleeve, from the inside out, includes a telescopic rubber sleeve, a corrugated heat insulation sleeve, and a wear-resistant fabric sleeve. The telescopic rubber sleeve is fitted snugly onto the outer wall of the telescopic water pipe. The corrugated heat insulation sleeve includes several corrugated units connected end to end. Each corrugated unit includes a crest and a trough. The wear-resistant fabric sleeve is woven and fixed to the crest of the corrugated unit. An elastic tightening ring is fitted over the trough of the corrugated unit.

[0009] Preferably, a plurality of integrally formed limiting rings are provided at intervals on the outer wall of the telescopic rubber sleeve, and the plurality of limiting rings correspond one-to-one with the troughs of the corrugated heat insulation sleeve.

[0010] Preferably, the outer edge of the limiting ring is provided with a limiting ring groove, and the inner wall of the elastic constricting ring is provided with an inner convex ring, which compresses the crest of the corrugated unit into the limiting ring groove.

[0011] Preferably, the corrugated heat insulation sleeve includes a corrugated fabric sleeve layer and a heat insulation coating applied to the corrugated fabric sleeve layer.

[0012] (III) Beneficial Effects

[0013] This utility model provides a high-temperature resistant, high-strength, multi-layer fabric sleeve. It has the following beneficial effects:

[0014] 1. In this utility model, the elastic constriction ring can compress the corrugated unit's trough into the limiting ring groove, forming a limiting in the tensile direction. This allows the corrugated heat insulation sleeve and the wear-resistant cloth sleeve to expand and contract synchronously with the telescopic rubber sleeve in the tensile direction. The telescopic rubber sleeve is fitted on the outside of the telescopic water pipe, and the left and right lower limiting rings of the elastic constriction ring protrude inward, hugging the outer wall of the telescopic water pipe. This ensures that the contraction amount of the multi-layer cloth sleeve and the telescopic water pipe is consistent, preventing the cut telescopic water pipe from retracting into the cloth sleeve and facilitating the repair of broken telescopic water pipes.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] This utility model embodiment provides a high-temperature resistant, high-strength, multi-layer fabric sleeve, such as... Figure 1-2As shown, the device includes a multi-layered fabric sleeve fitted over a telescopic water pipe. From the inside out, the multi-layered fabric sleeve comprises a telescopic rubber sleeve 1, a corrugated heat-insulating sleeve 2, and a wear-resistant fabric sleeve 3. The telescopic rubber sleeve 1 fits snugly against the outer wall of the telescopic water pipe. The friction between the inner wall of the telescopic rubber sleeve 1 and the outer wall of the telescopic water pipe helps maintain a certain degree of consistency between the telescopic rubber sleeve 1 and the telescopic water pipe's expansion and contraction. Several integrally formed limiting rings 4 are spaced apart on the outer wall of the telescopic rubber sleeve 1, each corresponding to a trough of the corrugated heat-insulating sleeve 2. Limiting ring grooves 5 are formed on the outer edge of each limiting ring 4. The corrugated heat-insulating sleeve 2 includes a corrugated fabric layer and a heat-insulating coating applied to the corrugated fabric layer. The corrugated heat-insulating sleeve 2 includes several corrugated units connected end-to-end. Each corrugated unit includes crests and troughs. The wear-resistant fabric sleeve 3 is woven and fixed to the crests of the corrugated units. A protective fabric sleeve 3 is fitted over the troughs of the corrugated units. An elastic retaining ring 6 is sleeved at the corresponding limiting ring 4. The inner wall of the elastic retaining ring 6 is provided with an inner convex ring 7. The inner convex ring 7 squeezes the crest of the corrugated unit and fits into the limiting ring groove 5. The elastic retaining ring 6 can squeeze the limiting ring 4, causing the inner wall of the limiting ring 4 to bulge inward and press tightly against the outer wall of the telescopic water pipe, so that the outer wall of the telescopic water pipe has a corresponding concave shape. This further increases the consistency between the telescopic rubber sleeve 1 and the telescopic water pipe in the telescopic direction. By clamping the trough of the corrugated unit in the limiting ring groove 5 through the elastic retaining ring 6, the position of the trough of the corrugated unit can be kept consistent with the telescopic rubber sleeve 1 in terms of telescopic amount. The wear-resistant cloth sleeve 3 is woven into the crest of the corrugated unit, so that the wear-resistant cloth sleeve 3 is related to the shrinkage amount of each corrugated unit. This can realize that multiple cloth sleeves can tightly hug the telescopic water pipe, preventing the telescopic water pipe from shrinking into the multiple cloth sleeves and facilitating the repair of the telescopic water pipe.

[0020] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
