Abstract
An oil filling pipe joint assembly comprises a metal connection pipe (1) and a connection nut (2) sleeving one end of the metal connection pipe (1). An annular slot (1.1) for inserting an oil filling machine rubber pipe (3) is formed in the other end of the metal connection pipe (1), an annular pawl (4) for preventing the oil filling machine rubber pipe (3) from being pulled out is arranged on the inner circumferential lateral wall of the annular slot (1.1) at the position close to the central axis of the annular slot, the pawl tip of the annular pawl (4) faces the groove bottom of the annular slot (1.1), and threads (5) are arranged on the inner circumferential lateral wall of the annular slot (1.1) far away from the central axis of the annular slot. The oil filling pipe joint assembly has good sealing performance.
Description
Technical field
The utility model relates to oilling machine sebific duct and nozzle interconnection technique field, is specifically a kind of oil filling pipe adapter assembly.
Background technique
In gas station, oilling machine sebific duct often adopts oil filling pipe adapter assembly to realize both connections with being connected of nozzle, comparatively common oil filling pipe adapter assembly generally comprises a metal connecting tube and a nut connector at present, nut connector is set in the end of metal connecting tube for being connected with nozzle, and the head of oilling machine sebific duct connects oilling machine sebific duct for plug-in mounting.Although the oil filling pipe adapter assembly of this structure can be realized being connected of oilling machine sebific duct and nozzle, along with the prolongation of service time, the sealability between oilling machine sebific duct and metal connecting tube can reduce, thereby occurs draining phenomenon.
Model utility content
The technical problems to be solved in the utility model is that a kind of oil filling pipe adapter assembly of good seal performance is provided.
For solving the problems of the technologies described above, the technological scheme that the utility model provides is: comprise metal connecting tube and the attaching nut who is set in metal connecting tube one end, the other end of described metal connecting tube is provided with the ring-type slot for plug-in mounting oilling machine sebific duct, inner circumference sidewall near ring-type socket center axis on this ring-type slot is provided with the annular pawl that prevents that oilling machine sebific duct from extracting, the crown of annular pawl is towards ring-type slot bottom land, and the inner circumference sidewall away from ring-type socket center axis on this ring-type slot is provided with screw thread.
Adopt after above structure, the utlity model has following advantage: oil filling pipe adapter assembly of the present utility model is provided for the ring-type slot of plug-in mounting oilling machine sebific duct by the end at metal connecting tube, on two inner circumference sidewalls of ring-type slot, annular pawl and screw thread are set respectively, and the crown of annular pawl is towards ring-type slot bottom land, after like this in oilling machine sebific duct is plugged in this ring-type slot, annular pawl just can be stung out the inwall of oilling machine sebific duct, and the screw thread on ring-type slot also can tightly be bitten oilling machine sebific duct, make together with oilling machine sebific duct fits tightly with metal connecting tube, like this under the double action of screw thread and annular pawl, oilling machine sebific duct is closely connected with metal connecting tube, sealability increases greatly, there will not be draining phenomenon, and pawl is firmly bitten oilling machine sebific duct, using external force to pull out oilling machine sebific duct can not make it by pull-off, be fallen yet.
Further, the cross section of described annular pawl is triangle, described annular pawl becomes spaced set, cross section is that leg-of-mutton annular pawl is more easily bitten oilling machine sebific duct, make that oilling machine sebific duct is more difficult to be fallen by pull-off, form the annular pawl of equidistantly arranging and evenly bite oilling machine sebific duct, be more difficult for making oilling machine sebific duct to be fallen by pull-off.
Accompanying drawing explanation
Fig. 1 is the sectional structure schematic diagram after oil filling pipe adapter assembly of the present utility model and the assembling of oilling machine sebific duct.
Fig. 2 is the sectional structure schematic diagram of oil filling pipe adapter assembly of the present utility model.
As shown in the figure: 1, metal connecting tube, 1.1, ring-type slot, 2, attaching nut, 3, oilling machine sebific duct, 4, annular pawl, 5, screw thread.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in the figure, oil filling pipe adapter assembly of the present utility model, comprises metal connecting tube 1 and the attaching nut 2 who is set in metal connecting tube 1 one end.The other end of described metal connecting tube 1 is provided with the ring-type slot 1.1 for plug-in mounting oilling machine sebific duct 3.Inner circumference sidewall near ring-type socket center axis on this ring-type slot 1.1 is provided with the annular pawl 4 that prevents that oilling machine sebific duct 3 from extracting, and the crown of annular pawl 4 is towards ring-type slot 1.1 bottom lands.Inner circumference sidewall away from ring-type socket center axis on this ring-type slot 1.1 is provided with screw thread 5, and described screw thread 5 is V thread screw.
In the present embodiment, the cross section of described annular pawl 4 is triangle, described 4 one-tenth spaced sets of annular pawl.
Oil filling pipe adapter assembly of the present utility model arranges ring-type slot 1.1 by the end at metal connecting tube 1, by this ring-type slot 1.1, oilling machine sebific duct 3 can be plugged in groove, this metal connecting tube adopts the structure of ring-type slot to carry out plug-in mounting oilling machine sebific duct, compared with prior art, after oilling machine sebific duct is plugged in groove, realized close-fitting, good sealing effect, add on the inner peripheral wall of ring-type slot 1.1 and be respectively equipped with annular pawl 4 and screw thread 5, annular pawl 4 is tightly bitten oilling machine sebific duct, effectively prevented that oilling machine sebific duct is pulled out, increased the sealability of metal connecting tube and oilling machine sebific duct simultaneously, and screw thread makes the precession in a spiral manner of oilling machine sebific duct, make oil machine sebific duct and metal connecting tube close-fitting more, also both sealabilities have been increased simultaneously.
Claims (2)
1. an oil filling pipe adapter assembly, comprise metal connecting tube (1) and be set in the attaching nut (2) of metal connecting tube (1) one end, it is characterized in that: the other end of described metal connecting tube (1) is provided with the ring-type slot (1.1) for plug-in mounting oilling machine sebific duct (3), the upper inner circumference sidewall near ring-type socket center axis of this ring-type slot (1.1) is provided with the annular pawl (4) that prevents that oilling machine sebific duct (3) from extracting, the crown of annular pawl (4) is towards ring-type slot (1.1) bottom land, the upper inner circumference sidewall away from ring-type socket center axis of this ring-type slot (1.1) is provided with screw thread (5).
2. oil filling pipe adapter assembly according to claim 1, is characterized in that: the cross section of described annular pawl (4) is triangle, and described annular pawl (4) becomes spaced set.
