The utility model has the advantages that anti-losing function is achieved, and the simple installation can be realized. The installation time can be saved. The fabrication cost and the die cost of parts can be saved. The waterproof function and dust prevention function can be realized. The whipping prevention can be realized. The pretension function, pre-installation and mistake proofing of the parts can be realized by adopting the design.

Description

The anti-drop device that cover plate connects

Technical field

The utility model relates to the connection set between a kind of plate part and the lid shape part, particularly relates to a kind of anti-drop device that the cover plate that is connected between automotive plastic parts and the sheet metal part connects that is mainly used in.

Background technique

Part generally adopts seizing type with easy connection the between the part at present, perhaps the viscose glue stick type.And these Placements only play simple installation function, in case buckle or viscose glue lost efficacy, just can have to cause coming off and losing of part.

Summary of the invention

Lost efficacy in case the purpose of this utility model just provides a kind of fastener, part can not come off and lose yet, and can realize simple and easy installation; Installation time can be saved; Save the manufacture cost of part; Save the component die cost; Can realize dust reduction capability; Can realize the anti-drop device that anti-shake cover plate connects.

Solution of the present utility model is such: at the rear portion of plate the positive stop hook groove is arranged, in the rear end of lid mousing-hook is arranged; The head of described mousing-hook is to the both sides convex, and boss is greater than the width of positive stop hook groove, and at the tight Board position of lid lid, the boss of mousing-hook is in the position that limited hook groove blocks.This mousing-hook had been introduced into a spacing groove before the cantilever hook enters draw-in groove, the width of this groove only can allow the mousing-hook side and enter, after this mousing-hook enters groove, revolve turn 90 degrees after, then this mousing-hook can not be deviate from from groove, reaches anti-detachment effect with this.

If there are at least two cantilever hooks the rear end at lid, there is the projection head in the outside of cantilever hook, and the size of relative projection head portion is greater than the size in hole on the plate, and when lid covers position at plate, the root of projection head is stuck in the rear side of plate.During use, cover in pushing course, the EDGE CONTACT of two its projection heads of cantilever hook and plate hole, respectively distortion to the inside is when the border movement of plate hole during to projection bottom root, because the elastic force effect return of cantilever hook, hook the edge of plate hole, to cover and fix, and play and realize simple and easy installation, save the installation time; Save the manufacture cost of part, save the component die cost, realize water-proof function, realize dust reduction capability; Realize anti-shakely, realize the pretension function, part has adopted this design, realizes installing in advance, realizes installing mistake proofing.

The utility model has the advantages that and realized anti-loss function, and can realize simple and easy installation, can save the installation time; Can save the manufacture cost of part, can save the component die cost, can realize water-proof function, can realize dust reduction capability; Can realize anti-shakely, part has adopted this design, can realize the pretension function, and part has adopted this design, can realize pre-installation, and part has adopted this design, can realize installing mistake proofing.

Embodiment

The utility model includes plate 1 and lid 2, and lid 2 is to snap onto on the hole of plate 1, at the rear portion of plate 1 positive stop hook groove 7 is arranged, and in the rear end of lid 2 mousing-hook 6 is arranged; The head of described mousing-hook 6 is to the both sides convex, and boss is greater than the width of positive stop hook groove 7, and in the tight plate of lid 2 lids 1 position, the boss of mousing-hook 6 is in the position that limited hook groove 7 blocks.A mousing-hook 6 is arranged at the bottom of lid 2, this mousing-hook 6 had been introduced into a spacing groove 7 before cantilever hook 3 enters draw-in groove, the width of this groove only can allow mousing-hook 6 sides and enter, after this mousing-hook enters groove, revolve turn 90 degrees after, then this mousing-hook can not be deviate from from groove.Reach anti-detachment effect with this.Described mousing-hook 6 head design are become arrow-shaped, can more easily mousing-hook be inserted in the positive stop hook groove.

For improving the effect that is connected of plate and lid, in lid 2 rear end at least two cantilever hooks 3 are arranged, there is projection 4 in the outside of cantilever hook 3, and the size of relative projection 4 head is greater than the size in hole on the

plate

1,2 cover in the position of plate 1 at lid, the root of projection 4 is stuck in the rear side of plate 1.

Also can there be a border rear end of lid 2 as the equiform projection head of cantilever hook.

In the present embodiment, described plate 1 has rearward extending card platform 5 on its limit, hole, and the root that covers the projection 4 of 2 rear ends is the termination that is stuck in card platform 5.Limit, hole at plate 1 is fluted, and the edge of lid 2 is to be stuck in this groove.

The utility model when mounted, two cantilever hooks 3 are in traveling process, the profile in hole contacts distortion to the inside respectively on its projection 4 and the plate 1; Perhaps cover 2 when mounted, the projection of a border is advanced under the promotion of power, and in traveling process, the profile by hole on the plate 1 is to its extruding, 4 distortion of the projection on the lid 2.

When lid 2 when being in place, the projection of two cantilever hooks 4 will break away from the profile in hole on the plate 1 and contact, part or fully recovery be out of shape; Perhaps when lid 2 when being in place, projection 4 break away from plate 1 on the contacting of profile in hole, partly or fully recover to be out of shape.

Recover two projections 4 of distortion, cooperate and cover 2 and the surface of contact of plate 1, will limit and cover 2 disengaging plates 1; Perhaps recover the projection 4 of distortion, cooperate and cover 2 and the surface of contact of plate 1, will limit and cover 2 disengaging plates 1.

Use-case of the present utility model has: in the installation of backplate decorative sheet, this decorative sheet is anchored on the panel beating of the vehicle body outside by screw under a kind of outside of car.Present technique is: adopt a lid that has cantilever hook and mousing-hook, lid is gone on this decorative sheet.Avoid screw head to be exposed to the outside.

The utility model also can be used with traditional cover plate linkage structure except being used with above-mentioned cover plate connection set.
