Abstract
The utility model discloses a large-size hose joint which comprises a joint core and a joint sleeve, wherein one end of the joint core is used as an inserting part into which a hose is inserted; the joint sleeve is sleeved outside the inserting part of the joint core and is used for pressing the hose together with the joint core; pressing teeth are arranged on the inner surface of the joint sleeve; and tooth-shaped bulges are arranged at the outer surface of the inserting part of the joint core. With the adoption of the structure of the hose joint provided by the utility model, as the tooth-shaped bulges are arranged at the outer surface of the inserting part of the joint core, the hose is pressed by the tooth-shaped bulges together with the pressing teeth of the joint core, so that the hose does not drop off from the part where the hose is pressed by the inserting part of the hose and the joint sleeve even the pressure inside the hose is more than 35MPa, the phenomenon of oil leakage of a pipeline is unlikely to happen, and the normal working of equipment is ensured.
Description
Technical field
The utility model relates to a kind of hose coupling, relates in particular to a kind of large scale hose coupling, is widely used in the technical field that needs use hydraulic system.
Background technique
Hose coupling is the key position of connection device and sebific duct; Conventional at present hose coupling generally includes a joint fuse and adapter sleeve; Joint fuse one end is the cutting graftage part of insertion flexible pipe, in use, and the cutting graftage part of earlier adapter sleeve being inserted in the joint fuse; Again the cutting graftage part of joint fuse is inserted in the flexible pipe, the cutting graftage part of adapter sleeve, flexible pipe, joint fuse is withheld together withholding on the machine at last.The shortcoming of existing this hose coupling is: the hose coupling of this structure can only be connected with undersized flexible pipe, when hose diameter is big, has six roots of sensation steel wire in the flexible pipe, and existing small size joint fuse and adapter sleeve can not be withheld flexible pipe securely; Simultaneously, the pressure in the flexible pipe is big, if the pressure in the flexible pipe reaches 35MPa when above, joint fuse cutting graftage part and adapter sleeve withhold that the flexible pipe place is easy to be washed open by the pressure in the flexible pipe, pipeline generation leakage of oil, thus influence the equipment proper functioning.
Summary of the invention
In order to overcome the deficiency of existing technology, the purpose of the utility model provides a kind of large scale hose coupling closely that cooperates with flexible pipe.
A kind of large scale hose coupling of the utility model; Comprise joint fuse and adapter sleeve; Joint fuse one end is for inserting the cutting graftage part of flexible pipe, and adapter sleeve is set in outside the cutting graftage part of joint fuse, together withholds flexible pipe with the joint fuse; The internal surface of said adapter sleeve is provided with withholds tooth, and the cutting graftage part outer surface of joint fuse is provided with toothed projections.
The cutting graftage part of said joint fuse is shunk and is formed the choke that diameter diminishes, and said sleeve one end is provided with the snap collar that bends inwards, and this snap collar is fastened in said choke.
Adopt the structure of the utility model hose coupling; Because of joint fuse cutting graftage part outer surface is provided with toothed projections; The tooth of withholding of toothed projections and joint fuse is together withheld flexible pipe, though the pressure like this in the flexible pipe more than 35MPa, flexible pipe also can not withheld flexible pipe from joint fuse cutting graftage part and adapter sleeve and deviate from; Pipeline is difficult for sending oil leakage phenomenon, guarantees the equipment proper functioning.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation:
Fig. 1 is the structural representation of the utility model large scale hose coupling.
Embodiment
As shown in Figure 1; A kind of large scale hose coupling of the utility model comprises joint fuse 1 and adapter sleeve 2, and joint fuse 1 one ends are for inserting the cutting graftage part 3 of flexible pipe; Joints sleeve jacket casing 2 is located at outside the cutting graftage part 3 of joint fuse 1; Together withhold flexible pipe with joint fuse 1, the internal surface of said adapter sleeve 2 is provided with withholds tooth 21, and cutting graftage part 3 outer surfaces of joint fuse 1 are provided with toothed projections 4.
The cutting graftage part 3 of said joint fuse 1 is shunk and is formed the choke 3 that diameter diminishes, and said sleeve 2 one ends are provided with the snap collar 22 that bends inwards, and this snap collar 22 is fastened in described choke 3.Joint fuse 1 adopts the cutting graftage part 3 of choke can be easy to insert in the flexible pipe like this.
The hose coupling of the utility model in use; The cutting graftage part 3 of earlier adapter sleeve 2 being inserted in joint fuse 1; To insert in the flexible pipes with the cutting graftage part 3 of the joint fuse 1 of reducing again, the cutting graftage part 3 of adapter sleeve 2, flexible pipe, joint fuse 1 withheld together withholding on the machine at last.Because of joint fuse cutting graftage part 3 outer surfaces are provided with toothed projections 4; Toothed projections 4 is together withheld flexible pipe with the tooth 21 of withholding of adapter sleeve 2, and toothed projections 4 compresses the steel wire in the flexible pipe, like this when fixing large-sized flexible pipe; Even have six roots of sensation steel wire in the flexible pipe; Pressure in the flexible pipe is more than 35MPa, and flexible pipe also can not withheld flexible pipe with adapter sleeve 2 from the cutting graftage part 3 of joint fuse 1 and deviate from assurance equipment proper functioning.
Claims (2)
1. large scale hose coupling; Comprise joint fuse and adapter sleeve; Joint fuse one end is for inserting the cutting graftage part of flexible pipe, and adapter sleeve is set in outside the cutting graftage part of joint fuse, together withholds flexible pipe with the joint fuse; It is characterized in that: the internal surface of said adapter sleeve is provided with withholds tooth, and the cutting graftage part outer surface of joint fuse is provided with toothed projections.
2. large scale hose coupling according to claim 1 is characterized in that: the cutting graftage part of said joint fuse is shunk and is formed the choke that diameter diminishes, and said sleeve one end is provided with the snap collar that bends inwards, and this snap collar is fastened in described choke.
