Abstract

A chain sheet with enhanced strength, which is a semi-ellipse, comprises a first face, a second face alternated with the first face, and a mounting hole of two interval devices and through the first face and the second face. The chain sheet also comprises a link part located in the center, and two connecting the link part and the top part located on the two reversal sides, and the max width of the link part is larger than the max width of the top part. The bearing intensity of the chain sheet and the using security can be improved by the widen design of the link part.

Description

The chain sheet of the chain that can gain in strength

Technical field

This novel chain sheet that relates to a kind of chain is meant a kind of chain sheet of chain of gaining in strength especially.

Background technique

General chain be in design by inside and outside chain sheet, chain rolls and chain rivet serial connection forms, described chain sheet normally presents 8 fonts, and comprise a waist, two ends that are engaged on the two opposite sides of waist, and two perforation that is located at respectively on the end, wherein, this waist is to bring together toward central authorities, that is the width of waist is narrow than the width of end, so its strength that can bear is less.The strength that the chain sheet that this kind waist is brought together can bear is about about 820kgf, but then can't bear when external force is bigger, so the chain that uses this kind chain sheet to be concatenated into causes the chain sheet to be broken apart by waist easily, chain is damaged can not continue to use.

Summary of the invention

Therefore, this novel purpose is promptly gained in strength and the chain sheet of the chain of Security providing a kind of.

So the chain sheet of this novel chain of gaining in strength comprises: one first, second of one and first interval, and two intervals are provided with and run through this first and second 's mounting hole.

Definition one connects center on line, two vertical these center on lines at the center, hole of these mounting holes and passes through the hole vertical line at the center, hole of mounting hole respectively.These hole vertical lines of mat define one and are positioned between perpendiculars convergence part, hole on this chain sheet, and two connect these convergence parts and position in the end of two opposite sides, and wherein the Extreme breadth of this convergence part is the Extreme breadth greater than the end.

By the width that increases this convergence part, make this novel chain sheet can bear stronger external force in the use, improve the Security on using simultaneously.

Fig. 2 is the front elevation of this preferred embodiment; And

Fig. 3 is the local assembled sectional view of this chain, shows the assembled relation of this preferred embodiment and other element.

Embodiment

About this addresses other technology contents, characteristics and effect before novel, in the following detailed description that cooperates with reference to one of a graphic preferred embodiment, can clearly present.

As shown in Figure 1, 2, 3, the preferred embodiment of this novel chain sheet 1 is a wherein member of a chain, this chain in design, be to form by majority serial connection unit 10 serial connections, described serial connection unit 10 comprise chain sheet that two internal and external partitions and waist bring together 1 ', two respectively the chain that is located between these inboard chain sheets 1 ' of the chain sheet 1, of position in these chain sheets 1 ' outsides roll 3, and one pass chain sheet 1 ', chain rolls 3, and links the chain rivet 4 of the chain sheet 1 in the outside.And the design of chain, also chain sheet 1 that can this is novel uses as inboard chain sheet, or the chain sheet of medial and lateral all uses this novel chain sheet 1.

The chain sheet 1 of present embodiment is to be positioned at the outside, approximately slightly oval, comprise: one first 11 and 1 second 12, two of internal and external partition between left and right every and run through this mounting hole 13 of first 11 and second 12, and two flanges 14 that center on mounting hole 13 respectively and give prominence to towards another chain sheet 1, wherein mounting hole 13 is to wear for chain rivet 4, and each flange 14 then is to snap in one of the contiguous interior side chain sheet 1 ' mounting hole 11 '.

First 11 of the chain sheet 1 of present embodiment comprises parallel this oval medial region 111 of second 12, and one around the outer region 112 that is connected medial region 111 peripheries, the thickness of this outer region 112 dwindles gradually and is connected to this second 12, and have an inner circumference edge 113 outstanding, and described mounting hole 13 is to run through second 12 from this medial region 111 than medial region 111.

Definition one connect these mounting holes 13 center, hole 131 center on line 5, two vertical these center on lines 5 and pass through the hole vertical line 6 at the center, hole 131 of mounting hole 13 respectively, these hole vertical lines 6 of mat are divided into three parts on this chain sheet 1, be respectively one to be positioned at the convergence part 15 of 6 of described hole vertical lines, and two ends 16 that are connected to 15 left and right sides, convergence part.Wherein have on this convergence part 15 two between the upper and lower every and be connected the linking side 151 of 6 of hole vertical lines, described linking side 151 is from connecting the past centre of one of these hole vertical lines 6 side evagination gradually, and an Extreme breadth W1 of this convergence part 15 is the Extreme breadth W2 greater than each end 16, and the Extreme breadth W2 of described each end 16 is distances of 162 of two intersections of one of finger ends 16 outer circumferential face 161 and hole vertical line 6.

This novel convergence part 15 widen design, make chain sheet 1 can bear stronger external force in the use, its the external force that can bear be about 1500kgf, in addition, inner circumference edge 113 designs of this outer region of first 11 112, the thickness of chain sheet 1 part is increased, also having increases the effect that is subjected to force intensity, avoids chain sheet 1 from the fracture of mounting hole 13 peripheral regions, the therefore chain that utilizes this novel chain sheet 1 to be formed, can bear stronger external force, also improve the Security when using simultaneously.

The above person of thought, it only is this novel preferred embodiment, when the scope that can not limit this novel enforcement with this, promptly the simple equivalent of doing according to this novel claim and novel description generally changes and modification, all still belongs in the scope that this novel patent contains.
