Abstract
The utility model relates to an anti-channel-broken and nail-pulled proofing steel plate of automatic pressurization The utility model is formed by that each side of a steel plate with a C-shaped cross section is provided with 1 to 3 fixing circular holes, a stressing slotted hole is arranged inside each circular hole, and a sink hole of a screw is arranged only inside the slotted hole; two inner folding lugs extend out of one side surface of the steel plate, two outer folding lugs extend out of the other side surface of the steel plate, and the folding lugs are provided with fixing holes. The utility model has the advantages that both of the two inner folding lugs are moved from the outer sides of both of the two slotted holes to the inner sides, so the distance between both of the two slotted holes is properly increased; therefore, both of the two inner folding lugs 2 bear the maximum of folding force, which alleviates the stress condition of both of the two slotted holes and improves obviously the fracture resistant performance of the steel plate.
Description
This utility model belongs to the medical apparatus class.
Existing, China Patent No. is 932355919 the flute profile nail-pulled proofing steel plate that pressurizes automatically; Be by section for the steel plate of shape, the every side of steel plate has 1-3 fixedly circular hole respectively; An afterburning slotted hole is arranged respectively in the circular hole inboard, and slotted hole only has screw counter bore in the inboard; Be extended with two inner foldable ears in side of steel plate, another side is extended with two outer foldable ears, on the folding ear fixedly circular hole is arranged, this steel plate in use, effect is reasonable on the whole, and its problem is: the most close on the steel plate is two slotted holes, and these the most close two holes also are the holes that is subjected to folding power maximum, caused the phenomenon that fractures, safety is relatively poor.
The purpose of this utility model is: provide a kind of safe, not the steel plate of frangibility.
The technical solution of the utility model is: based on the patent No. is 932355919 the flute profile nail-pulled proofing steel plate that pressurizes automatically, and two inner foldable ears are displaced in two slotted hole inboards.
Steel plate of the present utility model is owing to be displaced in two inner foldable ears the inboard of two slotted holes; Making what be subjected to folding power maximum is two inner foldable ears, reduces the force-bearing situation of two slotted holes, the good effect that the anti-breaking force of steel plate is significantly improved.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a side view.
1 is that section is among the figure ］ steel plate of shape, the every side of steel plate has 1-3 fixedly circular hole 5 respectively, and an afterburning slotted hole 3 is arranged respectively in circular hole 5 inboards, and slotted hole only has screw counter bore 6 in the inboard; Be extended with two inner foldable ears 2 in side of steel plate, another side is extended with two outer foldable ears 4, on each folding ear fixedly circular hole is arranged respectively.This utility model is that two inner foldable ears 2 are displaced in the inboard by the outside of two slotted holes 3, suitably increase the distance of two slotted holes, making what be subjected to folding power maximum is two inner foldable ears 2, alleviates the force-bearing situation of two slotted holes 3, facts have proved that the anti-performance that fractures of this steel plate is significantly improved.
