Description

Hose for sanitary ware

Technical Field

The utility model relates to a sanitary ware equipment field, specifically a hose for sanitary ware.

Background

In the sanitary equipment commonly used in bathrooms, a hose is usually used to connect the water supply device and the sanitary equipment.

Among the current hose structure, the inside inner core that is the embedding circular tube type usually of both ends, then at the inner tube with weave the outer banding overcoat pressfitting of pipe form of outer use of dictyosome and cramp, owing to need prevent the inner core off-site, the dynamics that the overcoat pressfitting cramps can the grow, thereby the outside-in transmits the fastening force to the inner core on through the inner tube with weaving the dictyosome, press from both sides tight inner core, this inner core that has just led to not have special anti off-site structure needs thickening wall thickness, bear the fastening force of overcoat, make the diameter at hose both ends reduce, lead to the holistic water capacity of hose to reduce, be unfavorable for the use.

SUMMERY OF THE UTILITY MODEL

To the above problem, the utility model provides a hose for sanitary wares.

In order to achieve the above purpose, the present invention is realized by the following technical solution: a hose for sanitary ware, comprising: the corrugated pipe is nested in the mesh grid.

Furthermore, the corrugated pipe is in a spiral shape, and the external thread at the tail part of the core is matched with the spiral inside the corrugated pipe;

the core is screwed at two ends of the corrugated pipe, so that the core is prevented from moving in one step.

Furthermore, the diameter of the part of the outer sleeve hooped on the woven mesh sleeve, which is positioned on the allowance groove, is smaller than the diameter of the two ends of the outer sleeve;

when the inner pipe and the braided net sleeve are pressed and hooped by the circular-tube-shaped jacket, the pressed part is positioned on a allowance groove arranged between two sections of external threads on the core, thereby further clamping and fixing the core.

Furthermore, the through hole of the head of the core is provided with a hexagonal prism-shaped groove, so that the core can be quickly installed by adopting a common hexagonal wrench.

Furthermore, the head of the core is in a two-layer ladder shape, the diameter of the outer layer is larger than that of the inner layer, and the inner layer of the head of the core is connected with the tail of the core; the diameter of the portion of the joint which is nested with the core is smaller than the diameter of the outer layer of the head of the core, so that the joint is clamped into the head of the core.

Advantageous effects

Compared with the prior art, the utility model discloses following beneficial effect has:

1. the utility model discloses an external screw thread and bellows matched with core are screwed at the both ends of bellows, prevent earlier that the core from running the position, from this in follow-up processing, alright reduce the overcoat and will apply to it the confinement power to alright adopt the bigger core of through-hole diameter, thereby enlarge the through-hole internal diameter at hose both ends, increase the holistic water capacity of hose, make its more convenient to use.

2. The utility model discloses when inner tube and the outer banding overcoat pressfitting of weaving the net cover with the pipe form cramp, the position of pressfitting lies in on the core on the surplus groove that is equipped with between two sections external screw threads, reaches from this to the core further screens fixed, still gives the space of cramping the position and slightly deforming to the central extruded bellows simultaneously.

Detailed Description

The technical solution of the present invention will be described clearly and completely with reference to the accompanying drawings, and obviously, the described embodiments are some embodiments, not all embodiments, and all other embodiments obtained by a person of ordinary skill in the art without creative work belong to the protection scope of the present invention based on the embodiments of the present invention.

Example one

As shown in fig. 1-4, the utility model provides a hose for sanitary ware, which structurally comprises: bellows 1 and woven wire netting 2, bellows 1 nestification is in woven wire netting 2, still includes core 3, overcoat 4 and

joint

5, 3 middle parts of core are equipped with the through-hole, 3 afterbody embeddings of core the both ends of bellows 1, joint 5 nestification is in the head of core 3, overcoat 4 cramps weave the both ends of

wire netting

2, 3 afterbody of core is equipped with external screw thread 3a, external screw thread 3a is in the afterbody of core 3 is equipped with both ends, two of core 3 interval department between the external screw thread 3a is equipped with surplus groove 3 b.
