Abstract
The utility model relates to a safety fast clamping fastener for a scaffold, which is composed of a base, a two-convolution press cover, a fastener, etc., wherein the fastener adopts a self-locking fastening device which is composed of a concentric type eccentric locking shaft and an H-shaped draw rod. The base is in a loose leaf type connection with one end of the press cover through the concentric type eccentric locking shaft, and a positioning slot at the other end of the press cover is fastened by and connected with the base through the fastener which is an H-shaped draw rod. One end of the draw rod is a sharp transverse link stopper which is vertical to the draw rod, and one end of the locking shaft is provided with a convex triangular or a concave triangular key for rotation. Compared with the prior art, the utility model has the characteristics of time saving, labour saving (the utility model can be fastened by only pulled for once), safety and reliability. In addition, the fastening of the utility model only needs 2 seconds as the fastening speed of the utility model is high and the efficiency can be enhanced by 24 times.
Description
The utility model belongs to general building buckle, particularly be series new type of safe press from both sides the reducing scaffold clasp soon.
Because the steel tube scaffold clasp that generally uses in the present building trade, what adopt is the screw and nut fastening structure, when installation or removal, generally all to rotate tens times clamp nuts or unclamp nut with spanner, (generally tighten or loosen a nut and approximately need 55 seconds-1 minute 30 seconds), and labor strength is too big, and is tired easily.Fastening degree is often not good, can cause the fastener landing easily, can cause the balladeur train accident when serious, jeopardizes workman's life security.In addition in work progress owing to expose to the sun and rain, mud spills and solidifies, and can cause screw, nut corrosion, influences mechanical strength after the screw corrosion, the carrying gravitational low is dangerous.And when dismounting, be difficult to take apart, have to adopt sawing method devastatingly sometimes, be unfavorable for that like this recovery of fastener is reused, and cause fastener damage and nut to lose easily.Therefore, each engineering its loss late after installing and using reaches more than 30% the maintenance cost height.
At the shortcoming that exists in the prior art, the purpose of this utility model provides a kind of novel structure, does not have detached accessories, and is in light weight, production efficiency is high, installing/dismounting is easily quick, fastening fireballing " new type of safe fast clamping scaffold fastening ".
A kind of new structure safety fast clamping scaffold fastening that the utility model provides.This scaffold clasp comprises: right-angle coupler, rotary buckle with to three kinds of similar steel pipe scaffold fastening clips of clasp.
" new type of safe fast clamping scaffold fastening " of the present utility model, be to constitute by pedestal and hyperbolical gland and securing member etc., the lock-bit fastener that securing member has adopted eccentric lock shaft of concentric type and I-shaped pull bar to constitute, pedestal is connected by the eccentric lock shaft loose-leaf of concentric type with gland one end, the other end locating slot of gland is fastenedly connected through securing member and pedestal, it is characterized in that, securing member is an I-shaped pull bar, one end of pull bar is the apiciform transom block vertical with pull bar, and the termination of lock shaft is provided with a protruding triangle or recessed triangle (also can be other a shape) rotation spoon part.
Wherein gland is hyperbolical and the reinforcing rib structure that contacts with steel pipe is arranged.
Wherein T shape pull bar crosspiece piece inner surface crown is T shape inclined-plane.Also can adopt T shape to face directly.
Wherein on one (or two) end axial plane of the eccentric lock shaft of concentric type, have draw-in groove, the spring catch sheet is set in draw-in groove.
Wherein the slot pitch of locating slot and groove depth are unequal on the gland, and its slot pitch is to widen gradually from outside to inside, and its groove depth is deepened from outside to inside gradually, has equal coupling mechanism force to adapt to non-standard caliber.
The utlity model has the theory structure novelty, characteristics such as safe and reliable, in light weight, cost is low, torque resistant, antiskid fall, installing/dismounting is easily quick.It is compared with the fastener of prior art, have laborsaving (mounting or dismounting only need be pulled), saving time, (fastening speed is fast, only needed for 2 seconds, compare with old fastener, raise the efficiency 24 times), few, the long service life of not pollution when producing, production efficiency height, maintenance cost, the proportion of goods damageds be extremely low, have better skid resistance, and has auto-lock function (tearing open not open with general tool), thereby improved safety in utilization.
For further specifying structure of the present utility model and feature, below in conjunction with drawings and Examples the utility model is described in further detail, wherein:
Fig. 1 is the structural representation of the utility model right-angle coupler.
Fig. 2 the utility model is to the structural representation of clasp.
Below in conjunction with accompanying drawing 1, Fig. 2 structure of the present utility model, embodiment and operating principle being done one describes in detail.Fig. 1 has provided right-angle coupler example structure schematic diagram of the present utility model, be by pedestal 4, gland 2,5 and I-shaped pull bar 1,6, lock shaft 8,9 constitutes, gland 2 and 5 reinforcing rib structures that adopt hyperbolical to contact with steel pipe, a termination at lock shaft 8,9 is provided with spoonful, the spoon part has adopted triangular structure, also can adopt other shape.I-shaped pull bar crosspiece piece side surface is the V-arrangement inclined-plane.Its operating principle is: hyperbolical gland 2,5 connects as one by eccentric lock shaft 8,9 of concentric type and pedestal 4.After steel pipe 3 or steel pipe 7 are installed on the pedestal 4, hyperbolical gland 2,5 is anchored on steel pipe 3 or the steel pipe 7, then I-shaped pull bar 1,6 is advanced in the locating slot of hyperbolical gland 2,5, locating slot adopts not equidistant (from narrow to wide) and does not wait deeply that (from shallow to deep) designs, and has equal coupling mechanism force to adapt to non-standard caliber.Utilize the special special tool of unblanking to make the lock shaft rotation by the spoon part of pulling on the lock shaft 8,9, when the recess surface of the flat part of rotation lock shaft 8,9 during towards this termination of axis hole of I-shaped pull bar 1,6, axis hole wall near this termination on recess surface and the I-shaped pull bar 1,6 contacts, pull bar 1,6 can rotate freely, and fastener is in releasing orientation.When the recess surface of rotation lock shaft 8,9 during towards that end of crosspiece piece of I-shaped pull bar 1,6, the recess surface does not contact with axis hole wall on the pull bar 1,6, and fastener is in locking state.On one or two ends axial plane of lock shaft 8,9, can also slot, 10 of spring catch sheets are set in groove can prevent that lock shaft 8,9 from dropping out from axis hole, also witness marker can be set on the end face of lock shaft 8,9, with clear and definite its lock shaft location status.
Fig. 2 is of the present utility model to clasp example structure figure, is two steel pipes 11,13 are placed in pedestal 17 and the gland 16, and with its locking, pull bar 12 adopts the structure identical with Fig. 1 with lock shaft 14, pull bar 12.Be installed with center-pole connecting ring 15 on the lock shaft 14.
The utility model compared with prior art has: laborsaving, save time, rational in infrastructure and use The advantage that life-span is long and use is safe.
