The utility model provides a technical scheme that its technical problem adopted is:
The utility model provides a mounting structure of empty filter syntonizer, includes empty filter outlet duct and syntonizer, and outlet duct and syntonizer are equipped with buckle connection structure, and buckle connection structure includes fastener and the fastener of withholding the fastener, the fastener includes body portion and the head that is bigger than body portion, and the corner junction of head and body portion is the right angle, be equipped with the open slot that supplies the head to withhold on the fastener, the inner wall of open slot opening part is the plane.
The head part of the clamping piece is completely buckled into the open slot, and the body part is clamped by the opening of the open slot.
The inner contour of the inner wall of the open slot is slightly larger than the head.
The resonator is provided with a plug connector, and the air outlet pipe is provided with a positioning connector for the plug connector to be plugged.
The positioning connector is internally provided with a step hole, the plug connector is inserted into the step hole, an annular groove is arranged at the corner of the step surface of the step hole, and the top of the plug connector is abutted against the step surface and is provided with a convex rib buckled into the annular groove.
And a locking ring is arranged on the outer wall of the positioning joint of the air outlet pipe.
The utility model has the advantages that: the utility model discloses fastener open slot inner wall and with the fastener head of inner wall contact, body junction be the plane among the buckle coupling mechanism, improve buckle joint strength between outlet duct and the syntonizer, reduce the possibility that the buckle connection pine takes off, realize the reliable connection to air cleaner outlet duct and syntonizer through simple structure.

The present invention will be further explained with reference to the drawings and examples.
FIG. 1 is a partial cross-sectional view of the prior art;
Fig. 2 is a schematic structural diagram of the present invention;
Fig. 3 is a schematic exploded view of the present invention;
FIG. 4 is a cross-sectional view taken at A of FIG. 1;
Fig. 5 is a sectional view at B of fig. 1.
Detailed Description
Referring to fig. 2 to 4, the mounting structure of an air filter resonator comprises an air filter outlet pipe 1 and a resonator 2, the outlet pipe 1 and the resonator 2 are provided with a buckle connection structure, the buckle connection structure comprises a buckle 21 and a clamping piece 11 buckled into the buckle 21, the clamping piece 11 comprises a body part 111 and a head part 112 larger than the body part 111, the corner connection part of the head part 112 and the body part 111 is a right angle, an open slot 22 for buckling the head part 112 is arranged on the buckle 21, and the inner wall of the opening of the open slot 22 is a plane.
Through the utility model discloses a structural design, when the buckle is connected and is dismantled, because the right angle of open slot 22 inner wall for the plane and clip head and body junction makes the dismantlement resistance increase, reduces the possibility that the buckle connection pine takes off, makes the buckle connection is more reliable.
Further, the head 112 of the clamping piece 11 is completely buckled into the opening groove 22, and the body 111 is clamped by the opening of the opening groove 22, so that the clamping connection is more reliable and is not easy to loosen.
Further, in order to prevent the head 112 of the clip member 11 from deforming against the inner top wall of the opening slot 22, the head 112 of the clip member cannot be completely fastened into the opening slot 22 of the fastener 21; the inner contour of the inner wall of the opening slot 22 is slightly larger than that of the head 112, so that the head 112 can be conveniently buckled after being extruded and deformed.
in a preferred embodiment, as shown in fig. 5, the resonator 2 is provided with a plug 23, and the outlet pipe 1 is provided with a positioning joint 12 for inserting the plug 23. Be equipped with step hole 13 in the position joint 12, bayonet joint 23 cartridge is in step hole 13, and step face corner of step hole 13 is equipped with annular groove 14, and bayonet joint 23 top is equipped with protruding muscle 24, and when bayonet joint 23 top butt was on the step face of step hole 13, protruding muscle 24 buckled into annular groove 14, made bayonet joint 23 and position joint 12 fixed butt joint, simple to operate is simple.
