Abstract

The invention relates to a large plastic plate matching structure based on cantilever buckles. The large plastic plate matching structure comprises a cover plate (1) and a basal plate (2), the buckles (10) and cover plate turning edges (11) are arranged on the periphery of the cover plate at intervals, and the inner side wall of the basal plate is provided with clamping groove bosses (21) matched with the buckles and limiting bosses (20) used for supporting the cover plate turning edges. When the cover plate turning edges are turned to the upper portion of the side wall of the basal plate, the lower end faces of the cover plate turning edges abut against the top surfaces of the limiting bosses. Each clamping groove boss comprises a rectangular cavity (210) extending in the Z direction, the top surface of each limiting boss is a vertical limiting surface (201), and circumferential direction limiting surfaces (202) perpendicular to the vertical limiting surfaces are arranged at the upper ends of the vertical limiting surfaces. The limiting bosses are utilized, the clamping groove bosses are matched with the cover plate turning edges, and the buckles are used for multi-point horizontal surface matching; compared with an existing method that cover plate turning edges and grooves in the side wall of the basal plate are directly buckled and the turning edges directly abut against the bottom surface of the basal plate, better assembly stability is achieved.

Description

A kind of large-sized plastic rubber plate cooperating structure based on cantilever snaps

Technical field

The present invention relates to a kind of plastic cement products cooperating structure taking conventional cantilever snaps as basic joint form.Can be widely used in the detachable connection of big-and-middle-sized plate.

Background technique

Cantilever snaps is a kind of removable fasteners that plastic parts coordinates that is widely used in, formed by the buckle on cover plate flange and the groove being opened on substrate sidewall, when use by among the groove of the direct holding of flange buckle, cover plate flange lower along large size be resisted against with substrate bottom surface on, between flange and substrate for curved surface tilts to contact, therefore this dependence flange and substrate sidewall buckle and both large size against assembly method support stiffness not high, Assembly stability is also poor, easily causes assembly deflections.

Summary of the invention

Technical problem to be solved by this invention is to provide a kind of cooperation buckle structure applicable to big-and-middle-sized curved panel piece, can, guaranteeing to promote Assembly stability under detachable performance prerequisite, guarantee matched edges even transition, and be convenient to the later stage modify of mould.

The technological scheme that the present invention addresses the above problem is as follows:

A large-sized plastic rubber plate cooperating structure based on cantilever snaps, comprises cover plate and substrate, is arranged at intervals with buckle and cover plate flange along the week edge of described cover plate, it is characterized in that:

The madial wall of described substrate is provided with the draw-in groove boss that matches with buckle and for supporting the positive stop lug boss of cover plate flange, in the time that cover plate flange is folded on substrate sidewall, the lower end surface of cover plate flange compresses mutually with the end face of positive stop lug boss.

As preferred version, described buckle comprises leg-of-mutton buckle head and the buckle back side,

Described draw-in groove boss comprises the rectangular enclosure extending along Z-direction, one side of the relative buckle head of described rectangular enclosure has convex edge, lower surface and the Z-direction of described convex edge are perpendicular, and in the time that buckle holding is in rectangular enclosure, the upper-end surface of described buckle head is pressed on the fin of convex edge.

Further again, to join buckle head in process and put under in rectangular enclosure for the ease of turning, described draw-in groove boss end face and substrate sidewall junction are provided with inclined guide surface.

Further, in the time that buckle holding is in rectangular enclosure, the distance of the inwall of described rectangular enclosure and the buckle back side, side is preferably 0.7mm, avoids Assembly Interference.Interference distance between described buckle head and convex edge is preferably 0.3mm.While assembling to realize, be buckled in the level contact under appropriate deformed state, improve fitment stability.

Further, the end face of described positive stop lug boss is vertical confined planes, and the upper end of described vertical confined planes is provided with the circumferential confined planes perpendicular with vertical confined planes.This structure is the Z-direction to cover plate and circumferentially spacing in order to realization.Because vertical confined planes is vertical with stripping direction, by contacting with cover plate flange bottom surface notch the pressure that offsets, realize spacingly to cover plate Z-direction multiple spot horizontal support, eliminate originally directly contacting caused cooperation destabilization problems because of flange and bottom curved surface.

Described circumferential confined planes and substrate sidewall junction are provided with guide surface.Can be convenient to like this assembly process cover plate slips into.

Further, in the time that circumferential confined planes is parallel with cover plate side flanging, the distance between the two is 0.2mm.After installation, utilize the equidistant contact of multiple spot to guarantee two circumferential closely cooperating.

Compared with prior art, beneficial effect of the present invention is:

A, use positive stop lug boss, draw-in groove boss coordinate cover plate flange, buckle to implement multiple spot horizontal plane and coordinate, and the direct buckle of groove, flange and substrate bottom surface on cover plate flange and substrate sidewall directly have better Assembly stability against method.

B, be less than the surface of contact of prior art by reducing cover plate flange lower end and the area of contact of vertical confined planes, significantly reduce working surface, for later stage die debugging facilitates.

C, the present invention compensate the extended distance of cover plate flange by the vertical confined planes height of positive stop lug boss, the interval of positive stop lug boss arranges can shorten flange length, improves rigidity of support.In die debugging process, only need the vertical confined planes of multiple spot to carry out local crawl processing, just can realize matched edges height fall adjustment, compare original flange, bottom surface directly more efficient against method.
