It elaborates to the present invention below in conjunction with drawings and examples.
Referring to Fig. 1 to a kind of mounting structure of plastic fuel tank fuel oil pipe clamp shown in Fig. 3, including fuel oil pipe clamp 1, feature
It is：Further include matching merge the screw base 3 for the fuel oil pipe clamp 1 limit, pass through the limit with plastic fuel tank edge 2
Screw base 3 and the screw 4 being connected with the fuel oil pipe clamp 1.By in 2 attachment screw seat 3 of plastic fuel tank edge, making
Obtaining fuel oil pipe clamp 1 can be fixed on by screw base 3 and screw 4 on plastic fuel tank edge 2, can either ensure fuel oil pipe clamp
1 is reliably connected with plastic fuel tank edge 2, and can improve the intensity of matching part, additionally it is possible to limit fuel oil pipe clamp 1
Position prevents fuel oil pipe clamp 1 from moving and rotating.
The screw base 3 includes the upper limit portion 31 being square and lower limit portion 32 in the form of annular discs；The plastic fuel tank
Edge 2 is equipped with screw bore 21；The upper limit portion 31 passes through the screw bore 21 to coordinate with the fuel oil pipe clamp 1,
It is close to the lower surface of the plastic fuel tank edge 2 upper surface in the lower limit portion 32.The upper limit portion 31 of screw base 3
Fuel oil pipe clamp 1 can be limited in the horizontal direction, can prevent fuel oil pipe clamp 1 from all around moving and rotating；Lower limit
Position portion 32 can ensure screw base 3 with the cooperation of screw bore 21 on plastic fuel tank edge 2 in place.After the completion of assembly, spiral shell
The head end of nail 4 is close to the bottom surface in lower limit portion 32, and lower limit portion 32 can play protection plastic fuel tank edge 2
Effect, prevents screw 4 from causing to damage to plastic fuel tank edge.
The upper surface of described upper limit portion 31 is equipped with groove 311, the plane of symmetry of the groove 311 and the through-hole in the horizontal direction
33 axial line is coplanar；The screw base 3 is vertically equipped with through-hole 33, and the screw 4 passes through the through-hole 33 and the combustion
Tubing clamp 1 is connected.Groove 311 enables to upper limit portion 31 more to hold when with screw bore 21 and the cooperation of fuel oil pipe clamp 1
It is yielding, it is easier for installation.
The screw bore 21 is square hole, and the outer surface in the upper limit portion 31 is matched with 21 interference of screw bore
It closes.After screw base 3 coordinates with screw bore 21, by the through-hole of 4 drivescrew seat 3 of screw, screw 4 has outward screw base 3
Active force, the value of interference fit of screw base 3 and screw bore 21 can be increased so that 21 jail of upper limit portion 31 and screw bore
Gu cooperation, prevents screw base 3 from falling off from plastic fuel tank edge 2.
The top edge in the upper limit portion 31 is equipped with guide surface 312.From when guide surface 312 can install screw base 3
Guiding role so that easier for installation quick.
The fuel oil pipe clamp 1 is equipped with the mounting hole for coordinating with the screw 4, and the medial surface of the mounting hole is equipped with
Pawl 11, and the lower part of the mounting hole is to limit square hole 12 with 31 corresponding matching of upper limit portion.Pawl 11 has screw 4
It promptly acts on, can prevent fuel oil pipe clamp 1 from deviating from.
The fuel oil pipe clamp 1 includes deck 13, the card lid 14 with the deck 13 cooperation, and the deck 13 and card lid 14 are close
The position on the left side is that the position of rotation connection, middle part and close the right is clamping；And the left part of the deck 13 and Ka Gai 14 and
Right part is correspondingly provided with card slot 15.It can facilitate and assembly or disassembly is carried out to fuel pipe, and can ensure that fuel pipe is reliably fixed.
There are gap a between 14 right hand edge of card lid and the top right edge of deck 13.It being capable of the opening of convenient card lid 14.
The fuel oil pipe clamp 1, screw base 3 are integral molded plastic molding, and plastic fuel tank is blow molding.Use can be reduced
Expect, reduce cost.
When assembly, screw base 3 is assembled on plastic fuel tank edge 2 first, i.e., by the upper limit portion 31 of screw base 3
Screw bore 21 is passed through from the lower section of plastic fuel tank edge 2, until the upper surface in 3 lower limit portion 32 of screw base and plastic oil
It is close to the lower surface of case edge 2；The guide surface 312 of 31 top edge of upper limit portion can play the guiding role in assembly, make
It is quick and easy for installation to obtain screw base 3；Groove 311 can be convenient for upper limit portion 31 to coordinate with screw bore 21, i.e. upper limit portion 31
It can be squeezed and be deformed inward by two parts that groove 311 is divided.It then will be in 4 drivescrew seat 3 of screw so that screw 4
Coordinate with the through-hole 33 on screw base 3, until the head end of screw 4 is close to assemble in place with the bottom surface in lower limit portion 32；
At this point, the upper limit portion 31 of screw base 3 by screw 4 to its outside active force so that the upper limit portion 31 of screw base 3 and spiral shell
The interference volume in nail seat hole 21 increases so that is more firmly mounted.Finally fuel oil pipe clamp 1 is assembled on screw 4, until fuel pipe
The bottom surface of card 1 is close to the upper surface of plastic fuel tank edge 2, that is, completes assembly；Fuel oil pipe clamp 1 installs internal surface of hole at this time
Pawl 11 and screw 4 on screw-thread fit, prevent fuel oil pipe clamp 1 from deviating from from screw 4；Limit square hole 12 and screw base 3
Upper limit portion 31 coordinates, and prevents fuel oil pipe clamp 1 from rotating.It is achieved in the fixation to fuel oil pipe clamp 1 and limit, and can ensure to fire
Tubing clamp 1 is reliably mounted at plastic fuel tank edge.
