The hose coupling disclosed by the utility model has the advantage that a hydraulic giant and other water tube fittings can be conveniently installed and removed from a faucet without any tool.

Description

A kind of hose coupling

Technical field

The utility model relates to a kind of pipe connecting device, particularly the joint of the flexible pipe that waters of a kind of gardens.

Background technique

People water to the gardens flowers and plants and generally use hose, one is connected on water tap, water in other end hose in tow, and people generally directly prick hose on water tap with iron wire, when iron wire is tightened, easily water pipe is crushed, when iron wire Zha Detaisong, water pipe easily comes off from water tap again, and the folding dress is also inconvenient, more existing hose couplings adopt four advance and retreat screws to be screwed on water tap, and this joint couples together very inconvenient equally, and are not connected with water tap and closely just easily leak.

The model utility content

Technical problem to be solved in the utility model is to overcome existing above-mentioned deficiency in prior art, and a kind of easy accessibility is provided, connects hose coupling closely.

For solving the problems of the technologies described above, a kind of hose coupling described in the utility model, comprise bellows, flexible pipe connector, overcoat pipe fitting, spring, steel ball and snap ring, the overcoat pipe fitting is enclosed within the first half of flexible pipe connector, spring housing is on flexible pipe connector, and in outer casing tube body, the flexible pipe connector first half is provided with cinclides, steel ball is located in the cinclides of flexible pipe connector, and snap ring is enclosed within the draw-in groove of the steel ball top flexible pipe connector first half;

Hose connector is class's body, the first half is hollow cylinder, Lower Half is the body of two inverted cones, and the internal diameter of the body of two inverted cones is less than the hollow cylinder of the first half, the first half and outside, Lower Half joint are provided with a circle bump, inside is provided with seal ring, and mouth of pipe outer wall place, first half top is provided with draw-in groove;

The lower end of overcoat pipe fitting has one to enclose the convex edge, its inwall is class's tube wall of up and down two-stage, and lower inner tubal wall diameter is greater than upper inner tubal wall diameter, and overcoat pipe fitting first half inner tubal wall slightly larger in diameter is in flexible pipe connector first half hollow cylinder diameter, and the inwall of overcoat pipe fitting upper pipes mouth is inverted cone;

Cinclides is inverted cone, and its inner tubal wall aperture is little, and the outer tube wall aperture is large;

Spring one end is against on flexible pipe connector on the bump of part, and the other end is against the upper and lower inner tube of overcoat pipe fitting joint;

Snap ring is located on the draw-in groove of the flexible pipe connector first half, and the slightly larger in diameter of snap ring is in overcoat pipe fitting diameter of inner pipe.

Compare with existing hose coupling, the utility model has the advantage of: installing/dismounting hydraulic giant, other pipe fittings and be installed on water tap convenient, need to be by any instrument.

Embodiment

as shown in Figures 1 to 4, a kind of hose coupling described in the utility model, comprise bellows 1, flexible pipe connector 2, overcoat pipe fitting 3, spring 4, steel ball 5 and snap ring 6, overcoat pipe fitting 3 is enclosed within the first half of flexible pipe connector 2, spring 4 is enclosed within on flexible pipe connector 2, and in outer casing tube body 3, flexible pipe connector 2 first halves are provided with cinclides 7, steel ball 5 is located in the cinclides 7 of flexible pipe connector 2, snap ring 6 is enclosed within the draw-in groove 8 of steel ball 5 top flexible pipe connector 2 first halves, hose connector 2 is class's body, the first half is hollow cylinder, Lower Half is the body of two inverted cones, and the internal diameter of the body of two inverted cones is less than the hollow cylinder of the first half, the first half and outside, Lower Half joint are provided with a circle bump 10, inside is provided with seal ring 9, seal ring 9 is used for preventing from leaking when hose coupling is connected with water tap, mouth of pipe outer wall place, first half top is provided with draw-in groove 8, the lower end of overcoat pipe fitting 3 has one to enclose convex edge 11, its inwall is class's tube wall of up and down two-stage, and lower inner tubal wall diameter is greater than upper inner tubal wall diameter, overcoat pipe fitting 3 first half inner tubal wall slightly larger in diameter are in flexible pipe connector 2 first half hollow cylinder diameters, the inwall of the overcoat pipe fitting 3 upper end mouths of pipe is inverted cone, cinclides 7 is inverted cone, its inner tubal wall aperture is little, the outer tube wall aperture is large, spring 4 one ends are against on the bump 10 of part on flexible pipe connector 2, the other end is against on overcoat pipe fitting 3, lower inner tube joint, snap ring 6 is located on the draw-in groove 8 of flexible pipe connector 2 first halves, and the slightly larger in diameter of snap ring 6 is in overcoat pipe fitting 3 diameter of inner pipe.

the user is when watering for the gardens flowers and plants, only hose coupling need to be installed, when hose coupling is connected with water tap, first the overcoat pipe fitting down wedging ring at the spring on flexible pipe connector until overcoat pipe fitting convex edge be against on the bump of flexible pipe connector, the interior steel ball of flexible pipe connector cinclides this moment outwards is rolled between the inverted cone tube wall of cinclides and overcoat pipe fitting, again flexible pipe connector first half cover feed cock, until faucet outlet props up the jointing place of the interior first half of flexible pipe connector and Lower Half, at this moment, cinclides on flexible pipe connector is just in time aimed at the groove on water tap, decontrol the overcoat pipe fitting, what the spring in the overcoat pipe fitting was replied tries hard to recommend moving overcoat pipe fitting along the flexible pipe connector upward sliding, can get into cinclides to the steel ball between inverted cone tube wall and cinclides, and the smaller part of steel ball partly exceeds in the groove that cinclides is stuck in water tap, this moment, hose coupling and water tap were even connected, during dismounting, also only need press the overcoat pipe fitting just can extract hose coupling from water tap, installation and removal do not need other assistant tools, namely fast convenient again.

Said circumstances is the explanation for one of the utility model, and unrestricted the utility model the scope of the claims, does not allly break away from the equivalence that the utility model does and implements or change, all should be contained in the scope of the claims of the present utility model.
