Abstract
The utility model discloses a kind of novel assembly fastened structure, its one end for being connected to oil delivery hose, the buckle press joint includes the interconnecting piece for connecting oil delivery hose, interconnecting piece is formed by withholding set and inner core, set is withheld to be fixed on inner core outer peripheral surface, it withholds to be formed between set and inner core and accommodates oil delivery hose wall and withhold slot, it is characterized in that, described withhold forms annular flange on set inner wall, arcuate bottom is formed on the bottom for withholding slot, buckle press joint has the function of good leakproofness and firm fixation sebific duct, such as withhold set inside annular flange is set, extruding oil pipeline wall that can be closer, the lesser sub- flange of lateral dimension is set especially on the inner peripheral surface of annular flange, sub- flange can be smoothly embedded in oil pipeline wall, form better seal effect.
Description
Technical field
The utility model relates to a kind of connector of oil delivery hose, a kind of specifically novel assembly buckle press joint.
Background technique
In Chinese patent literature, an a kind of entitled utility model patent for the rubber hose coupling of compression molding sealing is disclosed,
Publication number is CN205781591U comprising inner core mesoporous, which is worn, is connected with interior sebific duct layer, and interior sebific duct layer outer end is turned over by molding
Side sulfidization molding is connect with inner core end face；Cladding is connected with casing play in the outer circle of interior sebific duct layer and close inner core outer end, close
Outer sebific duct layer is connected on the surface of casing play outer end；Sebific duct layer in vulcanization flange by the way that tip side to be faced to the connection of inner core end face
It squeezes locking and carries out first time sealing, and the interior sebific duct layer that connector end face is equipped with sealing ring and inner core end face upper overturning is squeezed
Flexible deformation carries out second and seals, and by squeeze tighten convex-concave tooth engaged that sleeve is connected with its inner hole interval successively will be outer
Sebific duct layer end and casing play, it is corresponding with the concave-convex clutch tooth that is connected with is spaced in inner core outer circle withhold it is connected.
Utility model content
The utility model provides a kind of novel assembly buckle press joint, solves oil delivery hose and buckle press joint excellent sealing
Technical problem, while the technical issues of also solve buckle press joint stress raisers, extend the service life of buckle press joint.
A kind of novel assembly buckle press joint, is connected to one end of oil delivery hose, which includes connection oil transportation glue
The interconnecting piece of pipe, interconnecting piece are formed by withholding set and inner core, are withheld set and are fixed on inner core outer peripheral surface, withhold between set and inner core
Form receiving oil delivery hose wall withholds slot, which is characterized in that described withhold forms annular flange on set inner wall, withholds the bottom of slot
Portion forms arcuate bottom.
The utility model also does following improvement:
Annular lateral dimension is formed on the inner peripheral surface of the annular flange is less than the sub convex of flange inner peripheral surface face lateral dimension
Edge.
The quil of several annular arrays is also set up on the inner wall for withholding set, the tip inclination direction of quil withholds slot
Bottom.
Two annular hoops are set on the outer peripheral surface for withholding set, two hoops respectively with annular flange and annular array
Quil is corresponding.
The tail end for withholding set forms the opotism structure turned up.
Buckle press joint has the function of good leakproofness and firm fixation sebific duct, is such as withholding setting annular inside set
It is lesser that lateral dimension is arranged in flange, extruding oil pipeline wall that can be closer especially on the inner peripheral surface of annular flange
Sub- flange, sub- flange can be smoothly embedded in oil pipeline wall, form better seal effect.
It is also set up on the inner wall for withhold set to the inclined several quils of trench bottom are withheld, quil is pierced into oil pipeline wall
It is interior, prevent oil pipeline wall from falling off.Opotism structure plays a protective role, and prevents the outer wall of oil pipeline from wearing.Slot is withheld to be formed
Arcuate bottom avoids bottom stress concentration from causing to be broken.
It elaborates with reference to the accompanying drawings and examples to the utility model.
Detailed description of the invention
Fig. 1 is the connection structure diagram of oil delivery hose and buckle press joint.
Fig. 2 is the cross-sectional view of buckle press joint.
The cross-sectional view of another embodiment of the room Fig. 3 buckle press joint.
Appended drawing reference
1 opotism structure, 2 hoops, 3 withhold set, and 4 hoops, 5 inner cores, 6 annular flanges, 7 sub- flanges, 8 quils, 9 withhold slot.
Specific embodiment
Such as Fig. 1, buckle press joint is connected to one end of the tube body 10 of oil delivery hose, and in conjunction with Fig. 2, which includes withholding
Set 3 and inner core 5, that withholds the tube wall that accommodating oil delivery hose is formed between set 3 and inner core 5 withholds slot 9.On the inner wall for withholding set 3
Annular flange 6 is set, as a further improvement, preferably again on the inner peripheral surface of annular flange 6 in the sub- flange 7 of one annular of setting,
The lateral dimension of sub- flange 7 is less than annular flange 6.
Such as Fig. 3, the inner peripheral surface of camber structure is also can be set in the end face of annular flange 6, can also play increase office in this way
The effect of portion's pressure improves sealing effect.
Such as Fig. 1 and Fig. 2, several quils are also set up on the inner peripheral surface for withholding set 3, such as quil 8, several quils are preferably annular
It is arranged in the inside for withholding set 3, and the bottom for withholding slot 9 is directed toward in the inclination of the tip of quil.Withhold slot 9 with arcuate bottom
Mechanism avoids stress caused by deformation from concentrating.
In order to avoid wearing the circumferential surface of tube body 1, the tail end for withholding set 3 forms the opotism structure 1 extended out.
