Abstract
The utility model discloses a hose coupling which comprises a coupling core and a coupling sleeve, wherein one end of the coupling core is an insertion part into which a hose is inserted; the coupling sleeve is sheathed outside the insertion part of the coupling core, and presses the hose together with the coupling core; the internal surface of the coupling sleeve is uniformly provided with more than four rings of pressing teeth; and the height of each pressing tooth is 12-17% of the wall thickness of the coupling sleeve. The structure disclosed by the utility model increases the height of the pressing teeth on the internal surface of the coupling sleeve; thus, when the hose of engineering mechanical equipment or oil pump is clamped between the coupling sleeve and the insertion part of the coupling core, the hose can easily sink into grooves formed by every two adjacent pressing teeth on the internal surface of the coupling sleeve; and therefore, steel wires in the hose can not be easily broken, and can not disengage due to the pressure in the oil duct, thereby prolonging the service life of the hose and ensuring the sealability of the oil transfer duct of the engineering mechanical equipment or oil pump.
Description
Technical field
The utility model relates to the parts in a kind of hose coupling, relates in particular to a kind of hose coupling.
Background technique
At present, in the oil circuit delivery line of engineering mechanical device (for example digging machine, road roller, loader or fork truck etc.) or oil pump etc., generally adopt hose coupling to connect flexible pipe and engineering mechanical device or oil pump.Conventional hose coupling generally includes a joint fuse and adapter sleeve, and joint fuse one end is for inserting the cutting graftage part of flexible pipe, and the adapter sleeve internal surface is provided with withholds tooth.In use; 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 withholding on the steel wire of tooth pressure in flexible pipe of adapter sleeve.The shortcoming of existing this hose coupling is: the adapter sleeve internal surface withhold the 7-10% that tooth height is generally the adapter sleeve pipe thickness; Because it is too low to withhold tooth height; So withhold tooth and joint fuse cutting graftage part when withholding flexible pipe jointly, be prone to the steel wire buckle in the flexible pipe disconnected; Simultaneously, it is sharp to withhold the tooth profile of tooth, also easily that the steel wire buckle in the flexible pipe is disconnected when withholding.In addition, joint fuse and flexible pipe are difficult for fastening, and flexible pipe is prone to withhold flexible pipe from the cutting graftage part of joint fuse with adapter sleeve to be deviate from, thus phenomenons such as generation leakage of oil.
Summary of the invention
In order to overcome the deficiency of existing technology, the purpose of the utility model provides a kind of flexible pipe and hose coupling is connected firmly and the hose coupling of flexible pipe long service life.
A kind of 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; Evenly be provided with the tooth of withholding more than four circles on the said adapter sleeve internal surface, the said height of withholding tooth is the 12-17% of adapter sleeve wall thickness.
The said tooth cross section perpendicular to axial direction of withholding is trapezoidal.
The said tooth of withholding is six circles.
Adopt the structure of the utility model; Increased the height of withholding tooth on the adapter sleeve internal surface; Like this when the hose clip of engineering mechanical device or oil pump is connected between the cutting graftage part of adapter sleeve and joint fuse; Flexible pipe is prone to sink on the adapter sleeve internal surface adjacent two to be withheld in the groove that tooth forms, and the steel wire in the flexible pipe is difficult for being buckled and breaks like this, and flexible pipe can not deviate from because of the pressure in the oil circuit yet; Thereby in the working life that not only can postpone flexible pipe, can also guarantee the sealing of engineering mechanical device or oil pump pipeline road.
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 hose coupling.
Embodiment
As shown in Figure 1; A kind of hose coupling of the utility model 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; Adapter sleeve 2 is located at outside the cutting graftage part 3 of joint fuse 1; Together withhold flexible pipe with joint fuse 1, evenly be provided with on said adapter sleeve 2 internal surfaces four circles above withhold tooth 4, the said height of withholding tooth 4 is the 12-17% of adapter sleeve 2 wall thickness.
Adopt the structure of the utility model; Increased the height of withholding tooth 4 on adapter sleeve 2 internal surfaces; Like this when the flexible pipe of engineering mechanical device or oil pump is withheld in adapter sleeve 2 and joint fuse cutting graftage part 3; Flexible pipe is prone to sink on adapter sleeve 2 internal surfaces adjacent two to be withheld in the groove 5 that tooth 4 forms, and the steel wire in the flexible pipe is difficult for being buckled and breaks like this, and flexible pipe can not deviate from because of the pressure in the oil circuit yet.
The said height of withholding tooth 4 is the 12-17% of sleeve 2 wall thickness, is preferably 14-15%.
When the height of withholding tooth 4 is compared increase not for a long time with existing, to the fastening DeGrain of flexible pipe; When the height of withholding tooth 4 increases when too much with existing comparing, it is inconvenient not only to withhold tooth 4 preparation processing, and wastes raw material, and when fixing flexible pipe, also is prone to exceedingly stretch flexible pipe, causes the steel wire in the flexible pipe also to be prone to buckled break.
Said to withhold tooth 4 cross sections perpendicular to axial direction be trapezoidal, withholds tooth 4 like this in withholding flexible pipe, and withholding tooth 4 can be disconnected with the steel wire buckle in the flexible pipe.
The said tooth 4 of withholding is preferably six circles.
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; Again the cutting graftage part 3 of joint fuse 1 is inserted in the flexible pipe; The cutting graftage part 3 of adapter sleeve 2, flexible pipe, joint fuse 1 is withheld together withholding on the machine at last, the steel wire in the flexible pipe sinks on adapter sleeve 2 internal surfaces adjacent two and withholds in the groove 5 that tooth 4 forms.
Claims (3)
1. 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: evenly be provided with the tooth of withholding more than four circles on the said adapter sleeve internal surface, the said height of withholding tooth is the 12-17% of adapter sleeve wall thickness.
2. hose coupling according to claim 1 is characterized in that: the said tooth cross section perpendicular to axial direction of withholding is trapezoidal.
