Specific embodiment

Referring to the accompanying drawing of this utility model embodiment, this utility model is described in more detail.However, this practicality is new Type can be realized in many different forms, and should not be construed as and limited by the embodiment for herein proposing.Conversely, proposing these Embodiment is that, in order to reach fully and complete disclosure, and it is of the present utility model those skilled in the art is understood completely Scope.In these accompanying drawings, for clarity, may be exaggerated the size and relative size in layer and region.

With reference to Fig. 1-2, this utility model provides a kind of plastic buckle, for connecting first structure part and the second structure Part, is not intended to limit the specific constructive form of first structure part and the second structural member in the present embodiment, and such as first structure part can Think automotive upholstery, the second structural member can be plates of automobile.

The plastic buckle is included for connecting the deck 1 of first structure part 3, and the lower end of deck 1 is connected with for inserting To the snapin part 2 in the installing hole of the second structural member 4；Deck 1 is by the head 102, connecting pole 103 for connecting as one from top to bottom And resilient disc, resilient disc is additionally provided with foam-rubber cushion 106 towards on the end face of 2 side of snapin part.This utility model is by deck 1 On be provided with resilient disc, flexure strip is pressed on the second structural member 4, and surrounding deformation produces pretightning force and causes the second structural member 4 will not Upper and lower play, while by foam-rubber cushion 106 is arranged on the lower surface of resilient disc, foam-rubber cushion 106 is located at the second structural member and bullet Between property disk, play a part of water proof and dust proof.

In the present embodiment, 1 upper end of deck is provided with a blind hole 101 for extending axially downward；Wherein, blind hole 101 is located at At 1 upper end center of deck, and blind hole 101 is extended in connecting pole 103.This utility model is by arranging blind hole in 1 upper end of deck 101, it is to avoid 1 wall unevenness of deck, cause product surface to shrink serious, while the setting of blind hole 101 can mitigate product weight, drop Low cost.

In the present embodiment, the external diameter of connecting pole 103 is less than the external diameter of head 102 and resilient disc；As shown in Figure 2, The installing hole of one structural member 3 is enclosed within connecting pole 103, and the relative end face of head 102 and resilient disc is pressed on first structure part 3, Head 102 and resilient disc push down first structure part 3, prevent first structure part play about 3.

Further, the root of 103 junction of head 102, resilient disc and connecting pole is fillet 107；This utility model exists On deck 1 with 3 assembling of first structure part at root carry out rounding, prevent root produce stress, cause deck to rupture.
