Abstract

The utility model relates to a connecting piece for a water supply hose, which comprises a rubber hose body, a connecting inner core inserted into a port of the rubber hose body, a sealing ring and an external nut. The connecting piece is characterized in that a locking sleeve is arranged outside the rubber hose body and closely sleeved with the outer wall of the rubber hose body; a lower port of the connecting inner core takes a reducing frustum shape, is inserted into the rubber hose body and adopts an interference fit relationship with the inner wall of the rubber hose body; an external thread correspondingly tightened and connected with the locking sleeve is arranged in the middle of the connecting inner core; and the external nut is sleeved and buckled at the other end of the connecting inner core. By the adoption of the structure, since the locking sleeve works in with the connecting inner core, the difficult problem of connection of the traditional hose is solved, the length of the connecting piece for the hose can be freely and flexibly selected, and the connecting piece has the advantages of simplicity and convenience of construction operation, firm and reliable connection, excellent sealing performance, low production cost and the like.

Description

A kind of water supply hose connector

Technical field

The utility model belongs to the member that is tightly connected of the connection of pressure fluid conveyance conduit, the technical field of combination, particularly flexible pipe.

Background technique

At present, home-use water supply connecting tube mainly contains two kinds of metallic hose and glue flexible pipes, they are used for water supply line outlet and water tap, being tightly connected between the valves such as gondola water faucet, but reason owing to link, conventional art all adopts the way of fixed length, the termination that is flexible pipe is that jointing is installed non-dismountablely, such way, though made things convenient for the connection between the link, but people must measure the distance between water supply line outlet and the valve in advance, it is suitable to select again, the flexible pipe of fixed length, this causes to connect on the one hand reserves long or short problem, makes connection imperfect, owe attractive in appearance; On the other hand, link manufacturer must be equipped with the flexible pipe of various different size length, not only wastes but also bother.In addition, the flexible pipe termination adopts metal to tighten up, bind round dead mode fitting joint more at present, produces seepage or explosion, poor durability, and cost height because of metal is corroded easily.Therefore, be necessary traditional flexible pipe interconnection technique is improved.

The model utility content

The purpose of this utility model is the deficiency that overcomes above-mentioned prior art, proposes a kind of construction connection flexibly, simply, firm and reliable connection, good seal performance, the water supply hose connector that cost is low.

The purpose of this utility model is achieved by the following technical solution: a kind of water supply hose connector, include the sebific duct body, insert in connection inner core and seal ring and outer connected nut in the sebific duct body port, it is characterized in that: the external lock sleeve that is provided with of sebific duct, the tight socket of the external wall of lock sleeve and sebific duct, the lower end mouth that connects inner core is the reducing taper type, insert the sebific duct body, and with the inwall interference fit of sebific duct body, there is the corresponding outside thread that screws connection with lock sleeve at the middle part that connects inner core, and outer connected nut then overlaps to be buckled in and connects on the inner core the other end.Further, be screwing between convenient connection inner core and the lock sleeve, connecting inner core another port inwall is interior hexagon.The middle part outside thread that connects inner core locates to be provided with baffle ring to the greatest extent, and external nut sleeve is buckled in the baffle ring place and is connected with external valve.

Such structure, install when connecting, to connect inner core earlier and insert the sebific duct body, the front port that connects inner core is the reducing taper type, go deep in the sebific duct body, and the outside thread that connects the middle part of inner core exposes, the lock sleeve that is placed in the sebific duct body utilizes its internal thread to spin with the outside thread that is connected inner core, owing to connect the front port of inner core and the inwall interference fit of sebific duct body, make the inwall radial compaction sebific duct body of lock sleeve by spinning, connect thereby form deformable seal, make to connect the end that inner core is firmly attached to the sebific duct body.And the outer connected nut that cover is buckled on the connection inner core the other end is restrained between baffle ring and the lock sleeve, has certain axial freedom, and can realize being connected with other valves, pipe fitting.

Advantage is: 1, the connection operation is very easy, implements easily;

2, link can be installed on the hose body whenever and wherever possible, is not subjected to the restriction of body length, and adaptability is strong;

3, good sealing effect, the reliability height, cost of production is much lower than metalwork;

4, can install and remove repeatedly, be repeatedly used, the performance unanimity.

Embodiment

Referring to Fig. 1-Fig. 6, the water supply of present embodiment with hose connector mainly by sebific duct body 1, lock sleeve 2, outer connected nut 3, connect inner core 4, seal ring 5 constitutes, and wherein connects inner core 4 and lock sleeve 2 is cores, is working of plastics.Connecting inner core 4 is hollow structure, and its integral body can be divided into three ones of upper, middle and lowers, top be interior hexagon port 41 and with the baffle ring 42 of the corresponding coupling of outer connected nut 3 internal diameters; The middle part is the outside thread 43 corresponding with lock sleeve 2; The bottom is the port 44 that is the reducing taper type.Lock sleeve 2 inside have internal thread and its internal diameter just in time closely to mate with the external diameter of sebific duct body 1.

When installing and using, earlier outer connected nut 3 covers are buckled in and connect on the inner core 4, the lower end mouth 44 that connects inner core 4 is inserted in the sebific duct body 1, lower end mouth 44 is an interference fit with the inwall of sebific duct body 1, the reducing taper type of lower end mouth 44 makes sebific duct body 1 differential expansion protuberance, and the lock sleeve that is placed in sebific duct body 1 outer wall in advance can spin with the outside thread 43 that is connected inner core 4 middle parts for 2 this moments, along with screwing mutually of screw thread, lock sleeve 2 compresses mutually with the lower end mouth 44 that is connected inner core 4, makes be locked cover 2 of the port of sebific duct body 1 compress and form sealing fully with the lower end mouth 44 that is connected inner core 4.For convenience lock sleeve 2 be connected screwing mutually between the inner core 4, connection inner core 4 tops are interior hexagon ports 41, can insert Allen key and be helped to screw connection.After screwing, outer connected nut 3 just is in the rear of baffle ring 42 versatilely, connects inner core 4 upper ends and puts seal ring 5, cooperates outer connected nut 3, just can realize the sealing that is connected of sebific duct body 1 and other valves or pipe fitting.

Certainly, only enumerated a kind of preferred implementation here, the protection category that other is equal to, structure roughly the same all should belong to this patent repeats no more here.
