Abstract
The utility model discloses a spherical withholding hose connector which comprises a connector body and a locking nut (1); the connector body comprises a tail pipe part (4), a head pipe part (2) and a bent pipe part (3); one end of the bent pipe part is connected with one end of the head pipe part; the other end of the bent pipe part is connected with one end of the tail pipe part; the tail pipe part, the bent pipe part and the head pipe part are integrated, and the axis of the tail pipe part and the axis of the head pipe part form a 135-degree angle; the free end of the head pipe part is arranged in the locking nut and is movably connected with the locking nut; one end of the locking nut which is close to the free end of the head pipe part is provided with a circular limiting retaining ring; the inner diameter of the central hole of the circular limiting retaining ring is smaller than the outer diameter of the free end of the head pipe part; the end surface of the free end of the head pipe part is an arc-shaped surface; and the outline of the cross section of the locking nut is a regular pentagon. When the spherical withholding hose connector tightens the locking nut, a wrench is not easy to skid, and the sealing performance is high.
Description
Technical field
The utility model relates to a kind of joint, specifically is a kind of sphere fastening-pressing type hose coupling.
Background technique
Hose coupling is a kind of parts that will be used to connect flexible pipe and machinery equipment, and flexible pipe is generally transport pipe, pneumatic tube and water pipe etc.The head of hose coupling generally is provided with locking nut, this locking nut is generally positive hexagon nut, this hexagon nut is when tightening with spanner or unclamping, the clamping part of spanner is clamped on two parallel side walls of hexagonal locking nut outer side wall, like this when tightening locking nut, because the external frame of positive hexagonal locking nut is near circular, excessive if exert oneself or overexert and to make locking nut outer side wall corner angle wearing and tearing, spanner is skidded, thereby can not tighten locking nut, make the sealability of hose coupling and machinery equipment joint bad like this.
In addition, when the hose coupling head was connected with machinery equipment such as valve, the head at hose coupling was provided with the sealing that a resilient pad improves the joint usually.The resilient pad that is provided with in the head of the hose coupling of prior art is relative with the area of contact of the head of hose coupling less, so sealability is not high, particularly under the situation that oil pressure or air pressure are bigger in machinery equipment, oil or gas in the machinery equipment can overflow from the head of hose coupling, thereby the head seal performance of hose coupling is reduced.
The model utility content
The technical problems to be solved in the utility model is, overcomes the defective of above prior art, provides a kind of when tightening locking nut, and spanner is difficult for skidding, and the high sphere fastening-pressing type hose coupling of sealability.
Technical solution of the present utility model is, a kind of sphere fastening-pressing type hose coupling with following structure is provided: it comprises joint body and locking nut, described joint body comprises tail pipe portion, pipe portion and bent portion, one end of described bent portion is connected with an end of a pipe portion, the other end of bent portion is connected with an end of tail pipe portion, described tail pipe portion, bent portion and a three of pipe portion are one, and the axis of tail pipe portion becomes 135 degree angles with an axis of pipe portion; The free end of described pipe portion is arranged in the locking nut, and flexibly connect with locking nut, described locking nut is provided with the annular stop back-up ring near the free-ended end of a pipe portion, and the internal diameter of the center hole of described annular stop back-up ring is less than the free-ended external diameter of head pipe portion; The free end end face of described pipe portion is a cambered surface, and the cross section external frame of described locking nut is a regular pentagon.
After adopting above structure, the utility model sphere fastening-pressing type hose coupling compared with prior art, have the following advantages: the axis of the tail pipe portion of the joint body of this sphere fastening-pressing type hose coupling becomes 135 degree angles with an axis of pipe portion, make the tail pipe portion of the joint body after the installation can perk like this, be convenient to the replacing of flexible pipe; Because the cross section external frame of the locking nut of this sphere fastening-pressing type hose coupling is a regular pentagon, thereby make spanner when the clamping locking nut screwing, be difficult for incline wearing and tearing with locking nut, thereby when tightening locking nut, spanner is difficult for skidding, and makes sphere fastening-pressing type hose coupling tightr with being connected of machinery equipment; In addition, the free end end face of pipe portion is a cambered surface, when tightening locking nut and be connected with machinery equipment, the resilient pad of placing in the locking nut is big with the free-ended curved end area of contact of a pipe portion, thereby has improved the sealability of this sphere fastening-pressing type hose coupling and machinery equipment joint.
As a kind of improvement, the tail pipe portion of described joint body is provided with the flexuose projection.Be installed in the tail pipe portion of joint body at flexible pipe after, this flexuose projection has increased the inwall of flexible pipe and the frictional force of tail pipe portion, makes the flexible pipe difficult drop-off.
