Abstract

The utility model discloses a checkpost pore structure, including inserting and block the checkpost mounting hole of the rectangle structure of checkpost, the orientation both sides still are out of shape including setting up to be out of shape orientation one side or to set up respectively at the checkpost mounting hole at the checkpost mounting hole to the setting of checkpost mounting hole on the checkpost adheres to the piece, have the deformation hole of a determining deviation with the checkpost mounting hole. This practical optimization of taking out the diplopore structure to the checkpost hole, it has increased a deformation hole to warp direction one side or warp the direction both sides at the checkpost mounting hole respectively at the checkpost mounting hole, overcome current similar checkpost because the checkpost mounting hole hard warp the assembly that arouses and dismantles difficult problem, not only the assembly is easier with the dismantlement, the work efficiency is improved, still reduced because of dismantling the difficulty, two products at checkpost and checkpost hole place can not part and cause one of them piece to scrap and another condemned risk only together, the recycle who improves the product is rateed, and simultaneously, the product has lacked certain materials and relatively more lightweight, and save cost.

Clamp pore structure

Technical field

This utility model relates to clamp technical field, is specifically related to a kind of card sub-aperture with deformation hole.

Background technology

At present, existing clamp buckle structure (such as Fig. 1), clamp 3 is made up of the clamp head 31 of sphenoid structure and the clamp wall 32 under it, the clamp installing hole 4 of card sub-aperture only one of which rectangular configuration, when clamp head 31 inserts clamp installing hole 4, clamp installing hole 4 broadens by clamp head 31, and by rear, clamp installing hole 4 resiles.Existing clamp buckle structure there is problems in that due to card sub-aperture only one of which clamp installing hole 4 when dismounting, being all enclosed construction around clamp installing hole 4, it is more difficult that clamp installing hole 4 deforms, and when causing clamp 3 to assemble, contact engaging and separating force is bigger, during dismounting highly difficult, easily occur fracture, deformation damage.Conforming product rate only about 88%.

Utility model content

The technical problems to be solved in the utility model is: when existing buckle structure causes clamp 3 to assemble, contact engaging and separating force is relatively big, highly difficult during dismounting, the problem damage of fracture, deformation easily occur.

To achieve the above object of the invention, the technical scheme that this utility model is used is: provide a kind of clamp pore structure, clamp installing hole including the rectangular configuration inserting and blocking clamp, clamp installing hole is arranged on clamp attachment, it is characterized in that: also include being arranged on clamp installing hole deformation direction side or being separately positioned on clamp installing hole deformation direction both sides having deformation hole at regular intervals with clamp installing hole.

The rectangular opening that described deformation Kong Weiyu clamp installing hole is parallel.

Detailed description of the invention

Such as the clamp pore structure of Fig. 2, including the clamp installing hole 4 of the rectangular configuration inserting and blocking clamp 3, clamp installing hole 4 is arranged on clamp attachment 1.Compared with existing clamp pore structure, this clamp pore structure also includes the clamp installing hole 4 deformation direction both sides being arranged on clamp installing hole 4 deformation direction side, has deformation hole 5 at regular intervals with clamp installing hole 4, named in this spacing this utility model.Of course, if required, such as material is harder, when deflection is inadequate, respectively arranging a deformation hole 5 in clamp installing hole 4 deformation direction both sides is also feasible.

The deformation direction of clamp installing hole 4 is its money direction.

In the present embodiment, described deformation hole 5 is the rectangular opening parallel with clamp installing hole 4.

Such as Fig. 3 and 4, installing hole attachment 2 in this example and clamp attachment 1 and respectively automobile front beam grid body and grid counterpart, it is PP material, between body material thickness 2mm to 3.5mm.Clamp is made up of the clamp head 31 of sphenoid structure and the clamp wall 32 under it, and clamp wall thickness f is 2mm≤f≤3.5mm, and in automobile interior exterior room, PP material general thickness is in this range.

In the present embodiment, other sizes are as follows:

(1) clamp width a: this size requires to take according to product size and card relay.Such as, in this specific embodiment example, clamp width a is 13.5mm.

(2) clamp installing hole length b:

1.5a≤b≤3a(I)

In formula: b-clamp installing hole length, a-clamp width.
