Embodiment

Fig. 1 is the structural schematic diagram of the snap component 100 in the utility model embodiment；Fig. 2 is the left view of Fig. 1；Fig. 3 It is the top view of Fig. 1；Fig. 4 is the bottom view of Fig. 1；Fig. 5 is cross-sectional view of the Fig. 2 along line A-A.

Fig. 1 to Fig. 5 is please referred to, the snap component 100 in the present embodiment includes male fastener 10 and mother buckle 20；Male fastener 10 Including squeezing shaft part 11 and operating side；Operating side includes being connected to the head 12 for squeezing 11 one end of shaft part and the two sides from head 12 The motion arm 13 extended outward to form respectively；Mother buckle 20 be with along axially through through-hole K1 tubular structure, and female thread Part 20 has expansion arc 21, and the extruding shaft part 11 that expansion arc 21 is configured to hard to bear male fastener 10 squeezes axis when being inserted into through-hole K1 Section 11 is applied to the radial compression power of expansion arc 21 and radially swells.Optionally, the male fastener 10 and female thread in the present embodiment Part 20 is constituted using engineering plastics such as engineering plastics PA66-GF30.The material has high tenacity, wearability, light and anti- Corrosion, further ensures that structure is repeatedly dismantled and is not susceptible to damage.

A kind of application method of snap component 100 in the present embodiment are as follows: mother buckle 20 is first packed into suitable mounting hole In, then the extruding shaft part 11 of male fastener 10 fitted into the through-hole K1 of mother buckle 20 until the extrudings shaft part 11 squeezes makes It obtains and radially swells with compression fit in expansion arc 21 in the hole wall of mounting hole.In the present embodiment, due to setting operating side and Its motion arm 13, in some places for often needing to disassembly, such as air window washing liquid filler position, as long as will pass through when disassembly Male fastener 10 can be back-outed by forcing in motion arm 13 manually, thus the power that unloading keeps expansion arc 21 radially enlarged, and then can hold It changes places and takes out mother buckle 20, without borrowing additional auxiliary tool, components itself will not be caused to damage, mentioned significantly High structure Discerptibility and reusability, while the use of Surrounding Parts will not be influenced.The setting of motion arm 13 Torque is increased, hand is made to twist operation more efficiently.

In an embodiment of the present embodiment, optionally, being separately formed the motion arm 13 in 12 two sides of head is Laminated structure；Bilamellar motion arm 13 is coplanar, and the face passes through the central axes of male fastener 10.Under optional situation, as shown in figure Out, the motion arm 13 of two sides collectively forms butterfly wings.For the motion arm 13 for improving the butterfly wing in the present embodiment Bonding strength between head 12, the head 12 in the present embodiment has biggish axial width, so that the motion arm of two sides There is biggish connection length between 13 and head 12.Motion arm 13 and head 12 can be integrated molding or by such as welding Mode links together.The shape of motion arm 13 can be arranged according to the principle met convenient for users to finger force.

Mother buckle 20 can be set to diversified forms, such as in an embodiment of the present embodiment, see on the whole, female thread Part 20 is the tubular structure surrounded by wall.Axial one end of the wall of the mother buckle 20 of tubular structure offer it is multiple perforation its Along the circumferentially distributed of mother buckle 20, grooving C1 is axially extended to through wall the grooving C1, multiple grooving C1 of inner and outer circumferential surfaces The end end face, and be divided into multiple one end to fix the end of the wall of mother buckle 20, the other end can be squeezed by radially outer Compressive resilience radially distending sub- wall flaps 21a；The end of mother buckle 20 constitutes expansion arc 21.It is cut shown in the present embodiment Slot C1 is four, and four grooving C1 are separated to form four sub- wall flaps 21a.The axial outer end of through-hole K1 is set as bellmouth K2 knot Structure decomposites pair so as to squeeze shaft part 11 when extruding shaft part 11 insertion of male fastener 10 and be applied to the axial compression power of expansion arc 21 The radial component of each sub- wall flaps 21a, the radial component make a sub- wall flaps 21a at least partly radially swell.It is corresponding The outer end for squeezing shaft part 11 may also set up certain cone angle, to facilitate its force to sub- wall flaps 21a.In the present embodiment, squeeze Shaft part 11 is with externally threaded column；What the external screw thread that the through-hole K1 of mother buckle 20 was equipped with and squeezed shaft part 11 was threadedly engaged Internal screw thread squeezes shaft part 11 and is threadedly engaged in the through-hole K1 for screwing in mother buckle 20 by this.The length of thread segment can be according to reality Situation setting.

In an embodiment of the present embodiment, the axial inner ends of mother buckle 20 are equipped with to extend radially outward to be formed Ring cap 22.The outer end of ring cap 22 is equipped with the holding tank C2 formed along axial depression, and the extruding shaft part 11 of male fastener 10 cooperates When into through-hole K1, head 12 is contained in holding tank C2.When in use, mother buckle 20 is buckled into the peace for needing the structure connected When filling in hole, the axial limiting of mother buckle 20 can be realized by the face contact cooperation between ring cap 22 and the structure for needing to connect Positioning.And the holding tank C2 that recess is arranged accommodates head 12, and male fastener 10 can be improved and be screwed into depth, to reduce its exposed parts Height the space occupied.In an embodiment of the present embodiment, the axial outer end of the outer peripheral surface of mother buckle 20 is set as boring Shape face P1, to facilitate guidance mother buckle 20 to enter in mounting hole.

In summary describe, the snap component 100 in the present embodiment have without tool auxiliary can assemble and disassemble manually, disassembly side Just efficient beneficial effect is particularly suitable for being frequently necessary to the scene of disassembly, such as air window washing liquid filler position.

The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, for this For the technical staff in field, various modifications and changes may be made to the present invention.It is all in the spirit and principles of the utility model Within, any modification, equivalent replacement, improvement and so on should be included within the scope of protection of this utility model.
