Abstract
The utility model discloses a high-pressure rubber hose rotational tie-in, which pertains to a tie-in used to connect the high pressure rubber hose. The tie-in comprises a rotational tie-in seat and a joint. The tie-in seat is sheathed to the joint, easing rings placing between the tie-in seat and the joint, a corresponding ring groove arranging inside the connection wall of the rotational tie-in seat and outside the connection of the joint. A plurality of steel balls are arranged in the ring groove. For the high-pressure rubber hose rotational tie-in in use, an outer end of the rotational tie-in seat is connected to an injection pressure device and an outer end of the joint is connected with the rubber hose. As the joint of the high-pressure rubber hose rotational tie-in can correspond to the rotational tie-in and can freely rotate, the joint can not be distorted after the joint is sheathed with the rubber hose. At the same time, the utility model is simple and reasonable in structure and good in sealing performance and also has more high practical value.
Description
Technical field
The utility model belongs to field of mechanical technique, particularly a kind of joint that is used for the high-pressure rubber pipe connection.
Background technique
In the injection apparatus of hydraulic pressure, generally there are a shower nozzle or spray gun to be connected with injection apparatus by a sebific duct.The water that is sprayed or other liquid, are outwards penetrated by shower nozzle or spray gun through high-pressure rubber pipe by after the pressurization of injection apparatus.
In use,, often rotate, therefore just be easy to sebific duct is wound up, the operation that influence is actual because shower nozzle or spray gun are movable.Because the fluid pressure in the sebific duct is very high in use, so the common joint with rotating function can not satisfy its requirement.But, if adopt complicated structure to guarantee its sealing, can increase the cost of product again, make the user be difficult to accept.
Summary of the invention
The purpose of this utility model is at existing the problems referred to above in the high-pressure injection device, and a kind of high-pressure rubber pipe swivel that can freely rotate is provided, and makes it have characteristics simple and reasonable, favorable sealing property.
The purpose of this utility model is achieved like this: this high-pressure rubber pipe swivel comprises a swivel seat and a joint, the swivel cover for seat is connected on the joint, and between swivel seat and joint, be provided with rubber seal, be respectively equipped with corresponding annular groove at the madial wall of swivel seat joint and the outer side surface of joint joint, some steel balls are housed in the annular groove.
This high-pressure rubber pipe swivel in use, the outer end of swivel seat is connected to sprays on the pressurization device, the outer end of joint is connected with sebific duct.
In this high-pressure rubber pipe swivel, by between swivel seat and joint steel ball being set, the characteristic of utilizing steel ball to roll they are linked together, and joint can freely rotate with respect to the swivel seat.Here, rubber seal is to play seal action, leakage phenomenon occurs to prevent the joint.
In above-mentioned high-pressure rubber pipe swivel, corresponding to the annular groove place through hole is set on the described swivel seat, the internal diameter of through hole is slightly larger than the external diameter of steel ball, and at overcoat of outer side surface socket of swivel seat.When between swivel seat and joint, assembling steel ball, swivel seat and joints sleeve are connected together, steel ball is entered in the annular groove by through hole, put overcoat at last, stop that steel ball comes out to get final product in annular groove.
Advantage of the present utility model is:
1, can freely rotate with respect to the swivel seat owing to joint, so after glue pipe socket was connected to joint, phenomenon in use can not be distorted.
2, this high-pressure rubber pipe swivel is simple and reasonable, and favorable sealing property, has higher utility.
Description of drawings
Fig. 1 is the longitudinal sectional view of the high-pressure rubber pipe swivel that provides of the utility model.
Fig. 2 is the transverse sectional view of the high-pressure rubber pipe swivel that provides of the utility model.
Among the figure, 1, the swivel seat; 11, outer end; 12, through hole; 2, joint; 21, outer end; 22, rib; 3, steel ball; 4, seal ring; 5, overcoat; 6, annular groove.
Embodiment
As depicted in figs. 1 and 2, this high-pressure rubber pipe swivel comprises swivel seat 1 and joint 2.Swivel seat 1 is socketed on the joint 2, and is provided with two rubber seal 4 in their joint.Two rubber seal 4 are set, can increase the sealing of this swivel, to prolong its working life.
Be equipped with annular groove 6 at the madial wall of swivel seat 1 and the outer side surface of joint 2, and the position is corresponding.In the present embodiment, the cross section of described annular groove 6 be shaped as semicircle, its radius is slightly larger than the radius of steel ball 3.Like this, two annular groove 6 combination backs form a complete circular ring slot.
There is a through hole 12 at annular groove 6 places at swivel seat 1, and the internal diameter of through hole 12 is slightly larger than the external diameter of steel ball 3.After swivel seat 1 is socketed on the joint 2,, steel ball 3 is entered in the annular groove 6 by through hole 12.The quantity of steel ball 3 is decided according to the actual requirements, and generally is to be full of full annular groove 6.In the present embodiment, steel ball 3 has 26.Owing to be provided with steel ball 3, joint 2 just can't separate with swivel seat 1, but can freely rotate around rotating connection block 1.
After all steel balls 3 are loaded on annular groove 6, overlap an overcoat 5 again at the outer side surface of swivel seat 1.In the present embodiment, be connected by drive fit between overcoat 5 and the swivel seat 1.Overcoat 5 can stop that not only steel ball 3 comes out in annular groove 6, but also can play the effect of decoration, makes the product design of this swivel attractive in appearance.
As shown in Figure 1, in the present embodiment, the side of swivel seat 1 outer end 11 is provided with screw thread.Swivel seat 1 is connected with the injection pressurization device by screw thread.In the side of joint 2 outer ends 21 several anti-skidding ribs 22 are arranged.After glue pipe socket is connected to joint 2, utilize these anti-skidding ribs 22, sebific duct can firmly be connected with joint 2.
