For the problems referred to above, the scaffold clasp that has occurred a kind of wedging type on market, this fastener comprises sliding sleeve, relative be arranged on gland and hasp and the wedge block between gland and hasp on sliding sleeve, wherein the place, one end for snap fit of gland has gap, during use, by sliding sleeve cover therein on a scaffolding steel pipe, an other scaffolding steel pipe is placed between gland and hasp, then by rotation hasp, hasp being taken snaps in the gap on gland and rides on gland, by knocking the steel pipe of wedge block swelling simultaneously in sliding sleeve and between gland and hasp, thereby two steel pipes that intersect are bound together.Publication No. is to disclose respectively the scaffold clasp that contains said structure in the Chinese patent application of CN103195237A, CN103147566A, CN103089000A, CN103046737A, CN103233576A.

That above-mentioned wedging type scaffold clasp has is easy to use, dismounting advantage efficiently.But the many employings of its gland is the gland of traditional scaffold, and in the gland of traditional scaffold, owing to coordinating with nut, the outside at the position (clinch) at its place, U-shaped bayonet socket rear end is equipped with roughly rounded bowl configurations, this is obviously inoperative in wedging type scaffold clasp, and the existence of this structure also can affect the intensity of gland itself.In addition, due to what adopt, be the locking mechanism of overlapping, in work progress, likely there will be the problem of hasp rollback, once and this problem occurs, will directly cause the locking failure of corresponding fastener, bring unpredictable loss.

Summary of the invention

The purpose of this utility model is to provide a kind of fastener gland, to solve the problem that hasp that wedging makes fastener can accidental release.

Meanwhile, the purpose of this utility model is also to provide the scaffold clasp that uses above-mentioned gland.

In order to address the above problem, fastener gland is by the following technical solutions: fastener gland, comprise the articulated section of rear end and the clinch of front end, clinch is provided with for the bayonet socket with snap fit, and at least one side of the front end place at described bayonet socket on the lateral surface of clinch is provided with for stoping hasp to exit the Stop structure of bayonet socket when gland compresses corresponding steel pipe.

Described Stop structure consists of the bulge-structure being located on clinch lateral surface.

Described bulge-structure is the arc extending along fore-and-aft direction, and the peak of this arc is positioned at rear end.

Scaffold clasp is by the following technical solutions: scaffold clasp, comprise sliding sleeve, be articulated with the gland on sliding sleeve and be hinged on the hasp on sliding sleeve, gland comprises the articulated section of rear end and the clinch of front end, clinch is provided with for the bayonet socket with snap fit, and at least one side of the front end place at described bayonet socket on the lateral surface of clinch is provided with for stoping hasp to exit the Stop structure of bayonet socket when gland compresses corresponding steel pipe.

On lateral surface due to the clinch of this fastener gland, at the front end place of described bayonet socket, be provided with for stoping hasp to exit the Stop structure of bayonet socket when gland compresses corresponding steel pipe, therefore, in the process of using, when the wedge block wedging of fastener and after by two steel pipe bindings that intersect, described Stop structure can stop hasp (being the front end of bayonet socket) outside bayonet socket to slide, hasp does not outwards slide, gland just can not get loose, thereby can solve the problem that hasp that wedging makes fastener can accidental release.

Further, adopt the bulge-structure on clinch lateral surface can strengthen the intensity of fastener gland as Stop structure simultaneously; Adopt the bulge-structure of arc, and make the peak of arc be arranged in rear end can when hasp snaps in the bayonet socket of gland, to avoid interfering with corresponding hasp.
