The specific embodiment
Below in conjunction with Fig. 1 to Fig. 5, the utility model is described in further detail.
Consult Fig. 1～Fig. 5, a kind of for draw-bar or rope through hole, comprise the through hole 11 that is opened on vehicle bumper body 10 and with the suitable lid 20 of through hole 11, described through hole 11 is corresponding with the car puller hook position that is positioned at bumper/spoiler body 10 inner sides, on the interior plate face of described lid 20, be provided with two projections 21, two projections 21 are positioned at and cover that 20 interior plate face edges arrange and about covering 20 Central Symmetries, described through hole 11 edges arrange two supporting seats 12 about through hole 11 Central Symmetries, projection 21 and supporting seat 12 form against coordinate and both against face be circular-arc, the interior plate face edge of described lid 20 is also provided with two or more flexible claws 22 and coordinates with the inside edge inlay card of through hole 11 to be construed as limiting and cover the 20 outwards mobile spacing cooperations that depart from from through hole 11 places, flexible claw 22 is arranged with projection 21 intervals.
As preferred version of the present utility model, projection 21 is arranged to convex arc shaped here, supporting seat 12 is arranged to be concave arc shape.Described projection 21 is semicircle plate-like, and the card of this semi-disc is perpendicular to the plate face of lid 20, and 20 plate face setting is covered in the laminating of the straight section of semi-disc, and the arc section edge of semi-disc forms against coordinating with the concave arc on supporting seat 12.
In order to facilitate the setting of supporting seat 12, described through hole 11 disposed inboard have annual seat 13, and annual seat 13 is with through hole 11 with core layout, and the interior ring diameter size of annual seat 13 matches with through hole 11 apertures, and described supporting seat 12 is arranged on annual seat 13.The setting of annual seat 13 can also be played to the periphery of through hole 11 effect of reinforcement, and guaranteeing in use herein not can because of pressing, strength is excessive causes deformation.
The quantity of flexible claw 22 too much brings inconvenience to processing, and best, described flexible claw 22 has two, and the line that the line of two flexible claw 22 formations and projection 21 form intersects vertically.The every side of line that projection 21 forms arranges a flexible claw 22 can be effectively fixing by lid 20.
The set-up mode of flexible claw 22 is various, here provide a kind of comparatively simply but very practical a kind of scheme: one end of described flexible claw 22 is fixed on to be covered on 20, its section of suspending is provided with detent projection for being fastened on through hole 11 edges, the tooth top both sides of detent projection are inclined-plane, comparatively precipitous near lid 20 1 skew back faces, comparatively level and smooth away from lid 20 1 skew back faces.Its level and smooth skew back face convenient cap 20 fastens on through hole 11, and a precipitous skew back face prevents from covering 20 and departs from easily through hole 11, needs certain pressing force just can make to cover 20 disengagings.
In practical operation, by the corresponding site of pressing cover 20, under the cooperation of projection 21 and supporting seat 12, covering 20 can rotate, and wherein, has half cover plate will be to the outer side shifting of through hole 11, and second half cover plate is to the medial movement of through hole 11.Clearly, can there are deformation in the flexible claw 22 that mobile side edge thereof place arranges laterally, but 22 of the flexible claws of opposite side are along with cover plate is to through hole 11 medial movement, and deformation does not occur.The flexible claw 22 that therefore deformation described one of them can not occurred to replaces to block 23, and the cross section of described block 23 is L-type and is interlocked with through hole 11 edges.Block 23 is rigidity, and compared to flexible claw 22, its restriction covers 20, and from through hole 11 places, outwards the mobile effect departing from is better.The benefit that is all flexible claw 22 is that the arbitrary portion of pressing cover 20, can make to cover 20 rotations; But, when flexible claw 22 and block 23 are set simultaneously, can only press the cover plate that is provided with block 23 part and just can make to cover 20 rotations.
When lid 20 rotates certain angle with respect to through hole 11, just can directly lid 20 be taken off, carry out trailer or the operation of pulling a cart, now, because lid 20 is less and separated with car body, easily lose, therefore, the utility model will be furnished with flexible anticreep pawl 24 on the interior plate face of described lid 20, and anticreep pawl 24 is inserted in draw-in groove 14, described draw-in groove 14 is arranged on annual seat 13, and anticreep pawl 24 end that suspends is arranged to arrow shaped and draw-in groove 14 formation anticreeps and is coordinated.Like this, even if cover 20 separatedly with through hole 11, cover 20 and also by anticreep pawl 24, be connected with the draw-in groove 14 on annual seat 13, be difficult for loss.The end that suspends of anticreep pawl 24 is arranged to arrow shaped, after conveniently processing, inserts in draw-in groove 14; And after inserting draw-in groove 14, the natural separated position of arrow is greater than the groove width of draw-in groove 14, make both be unlikely to depart from.Certainly, where necessary, can press by manually pinching the two ends of arrow to make it produce certain deformation it is departed from from draw-in groove 14.
In addition, the shaft-like body integral body of the rope of described anticreep pawl 24 is bending, and itself and lid 20 one sections of being connected arrange perpendicular to lid 20 plate face, and its section of suspending is with to cover 20 parallel and postpone to the outside of covering 20.The benefit arranging is like this, when lid 20 is separated with through hole 11 when carrying out trailer or pulling a cart operation, covers 20 and can not cause interference to draw-bar or rope.And when lid 20 is fastened on through hole 11, the bending that anticreep pawl 24 presents also can play the outwards mobile effect departing from from through hole 11 places of certain restriction lid 20.And when covering a part of edge of 20, flexible claw 22 is set, another part edge arranges block 23, block 23 restrictions are covered 20 successfuls that outwards move disengaging from through hole 11 places and are better than flexible claw 22, therefore, the boundary plank face place between flexible claw 22 and projection 21 by described anticreep pawl 24.
