Abstract

The utility model discloses a bathing tube, comprising a plastic pipe, an inner core communicated with the hollow pressing coating tightly set-in covering the end of the plastic pipe, and a connecting nut sleeved at the end of the inner core; wherein, the inner core is a hollow sleeve arranged at the end of the plastic pipe, an inverted pawl and a shaft shoulder are arranged at the external surface of the inner core; an elastic rubber band is sleeved between the bottom of the inverted pawl and the shaft shoulder, and the inverted pawl of the inner core is embedded at the inner wall of the plastic pipe. The utility model has the advantages that: the bathing tube fully realizes the performance of the plastic pipe which is healthy and environment-friendly, and reduces the cost. Meanwhile, owing to the rubber band arranged outside the inner core, even if the plastic pipe is intenerated by the frequently passing hot water to result in the deviation of the plastic pipe from the pawl of the inner core, the rubber band is still tightly equipped into the inner core because of the strong heat resisting ability of the rubber band, preventing the inner core pulling out.

Description

A kind of bathroom flexible pipe

Technical field

The utility model relates to a kind of bath articles, but the bathroom flexible pipe that particularly a kind of heat supply water passes through.

Background technique

The bathroom flexible pipe is a kind of bath articles commonly used, generally include flexible pipe and the inner core and the nut that are fitted in hose end, owing to often need pass through hot water in these flexible pipes, so flexible pipe must have certain resistance to heat, traditional flexible pipe generally adopts rubber hose or plastic hose to make interior pipe, wherein the resistance to heat of rubber hose is better, hot water by the time tube wall be difficult for deforming, but this flexible pipe exists cost higher again, sanitation performance is relatively poor, product can not cycling and reutilization defective, and plastic hose is because cheap, nontoxic, peculiar smell is few, the hygienic environment-protecting performance is also better, so be able to remedy the deficiency of rubber hose, rubber hose is good but the resistance to heat of this plastic hose but is far from, therefore working as the hot water temperature who is passed through takes place when higher softening easily, the inner core that is fitted in hose end is deviate from gradually, caused and leak and the hot water accident of hurting sb.'s feelings.

Summary of the invention

In order to overcome the deficiencies in the prior art, the purpose of this utility model be to provide a kind of cheap, the hygienic environment-protecting performance is good and can effectively prevent the bathroom flexible pipe that the inner core at two ends is deviate from because of being heated.

The technological scheme that its technical problem that solves the utility model adopts is:

A kind of bathroom flexible pipe, comprise the inner core of plastic hose, the tight setting-in of hollow gland by being coated on the plastic hose end and be sleeved on the attaching nut of inner core end, described inner core is a hollow sleeve, be inserted into the plastic hose end, core outer surface is provided with the pawl and the shaft shoulder in described, be set with the elastic caoutchouc circle between the described shaft shoulder and the close pawl at shaft shoulder place, the described plastic hose end and the inner core shaft shoulder clamp rubber ring vertically, described gland and inner core radially compress described plastic hose and rubber ring, and make the inner core pawl embed the plastic hose inwall.

As the utility model most preferred embodiment, described gland end edge inwardly radially turns down and forms annular rib, and described rib is installed between the rubber ring and the inner core shaft shoulder.

As the further improvement to above-mentioned mode of execution, the interior outer core of described nut inboard is provided with seal groove, is installed with seal ring in the described seal groove.

The beneficial effects of the utility model are: because flexible pipe of the present utility model has adopted plastic hose, so just given full play to the performance of plastic hose hygienic environment-protecting, and product cost is lower, simultaneously owing to outside inner core, be set with rubber ring, and this rubber ring firmly is installed on the inner core pawl under the extruding of gland and plastic hose end face, even plastic hose softens because of the hot water effect of frequently passing through like this, cause plastic hose and inner core pawl to break away from, but because rubber ring has stronger resistance to heat, so rubber ring still can tightly be installed on outside the inner core, thereby play the effect that prevents that inner core from deviating from.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and Examples.

Embodiment

With reference to Fig. 1, Fig. 2, Fig. 3, a kind of bathroom flexible pipe, comprise plastic hose 1, the inner core 3 of the hollow gland 2 tight setting-ins by being coated on plastic hose 1 end and be sleeved on the attaching nut 4 of inner core 3 ends, described inner core 3 is a hollow sleeve, be inserted into plastic hose 1 end, described inner core 3 outer surfaces are provided with the shaft shoulder 32 and spaced vertically three groups of pawls 31, wherein pawl 31 is the inclined-plane away from the shaft shoulder 32 sides, 31 of the pawls at the described shaft shoulder 32 and the close shaft shoulder 32 places are set with elastic caoutchouc circle 5, the thickness of described rubber ring 5 is slightly larger than the described shaft shoulder 32 and near the distance of 31 of the pawls at the shaft shoulder 32 places, described plastic hose 1 end and the inner core shaft shoulder 32 clamp rubber ring 5 vertically, described gland 2 and inner core 3 radially compress described plastic hose 1 and rubber ring 5, and make inner core pawl 31 embed plastic hose 1 inwall, described gland 2 end edge inwardly radially turn down and form annular rib 21, described rib 21 is installed on 32 of rubber ring 5 and the inner core shaft shoulders, inner core 3 outer walls of described nut 4 inboards are provided with seal groove 33, are installed with seal ring 6 in the described seal groove 33.

Because what the flexible pipe in the present embodiment adopted is plastic hose, thus given full play to the performance of plastic hose hygienic environment-protecting, and also product cost is lower.Present embodiment is put into elastic caoutchouc circle 5 gland 2 and is close to gland rib 21 inboards when assembling, again plastic hose 1 plug-in mounting is gone in the gland 2, and make plastic hose 1 hold out against rubber ring 5, the seal ring 6 of in the seal groove 33 of inner core 3 outer ends, packing into, 33 of seal ring 6 and seal grooves also are drive fits, inner core 3 band pawls 31 1 ends pass the back in the nut 4 and go into plastic hose 1 from 21 side pressures of gland rib, because pawl 31 is the inclined-plane away from the shaft shoulder 32 sides, so inner core 3 can pass rubber ring 5 smoothly and enter in the plastic hose 1, and rubber ring 5 closely is installed between the shaft shoulder 32 and the close pawl 31 at the shaft shoulder 32 places, slightly thick rubber ring 5 can guarantee can be not gapped between itself and the adjacent shaft shoulder 32 and the pawl 31, radially push gland 2, plastic hose 1 and rubber ring 5 are deformed, the pawl 31 of inner core 3 outer walls embeds plastic hose 1 inwall, rubber ring 5 fully is filled between the shaft shoulder 32 and the close pawl 31 and gland 2 at the shaft shoulder 32 places, inner core 3 just firmly is installed in the plastic hose 1 like this, in use, even plastic hose 1 softens because of the hot water effect of frequently passing through, cause 31 disengagings of pawl of plastic hose 1 and inner core 3, because rubber ring 5 has stronger resistance to heat, so rubber ring 5 still can tightly be installed on outside the inner core 3, thereby play the effect that prevents that inner core 3 from deviating from.

Also can prevent external force damage plastic hose 1 outer surface in the utility model by outside plastic hose 1, coating coat of metal.
