Description
Technical field
The utility model relates to the auxiliary spare part of construction implement, and especially a kind of Outsourcing-type for fixing scaffold equipment is to clasp.
Background technology
The equipment of setting up of current building operations building site scaffold mainly carries out connecting with fastener, fastener is as the link between steel pipe and steel pipe, for the safety of scaffold, fastness and convenience play vital effect, because steel pipe has certain length, therefore for needing head to head between steel pipe and steel pipe in putting into practice, the situation that tail connects tail is many, just need such to clasp, Outsourcing-type conventional is at present all monolateral locking to clasp, namely locking mechanism is set at the joint of two steel pipes, because sometimes steel pipe is long, when Outsourcing-type fastener be used for fixing after, if act on power on steel pipe not evenly or steel pipe stressed directly when the two ends of steel pipe, the stress that the joint of two steel pipes produces is just very huge, this huge stress not only can make the joint of steel pipe produce deformation, the locking position of Outsourcing-type fastener also can be made time serious to come off or split, cause security incident, moreover the locking of Outsourcing-type fastener of the prior art is all that needs two spanners carry out just can completing to screw bolt and nut simultaneously, it is more inconvenient to operate, therefore the structure for Outsourcing-type this in prior art must be improved the environment just can tackling complicated building operations building site.
Utility model content
The purpose of this utility model is overcome above-mentioned the deficiencies in the prior art and provide a kind of Outsourcing-type for fixing steel pipe to clasp, solves when Outsourcing-type of the prior art causes fastener locking position come off or split and lock clasp because of unbalance stress and operates cumbersome problem.
For achieving the above object, the technical solution adopted in the utility model is:
There is the Outsourcing-type of balancing of stresses structure to clasp, comprise fastener body and the bolt for fixing, nut and pad, the two ends of described fastener body arrange two pairs of engaging lugs, be respectively the nut check end engaging lug of bolt insertion end engaging lug and the jaw shape being provided with perforate, bolt insertion end engaging lug is provided with and can forms the subsider of interference fit with nuts, described subsider is concentric with perforate, the inwall of fastener body is provided with the balancing of stresses structure that cross section is I-shaped groove, described balancing of stresses structure and the inwall of fastener body form double-layer tube wall and the joint being positioned at two steel pipes in fastener body is cut off by I-shaped groove.
As preferably, described subsider is key shape groove, and corresponding bolt is tee T bolt.
As preferably, described subsider is hexagon groove, and corresponding bolt is hex bolts.
The technical program mainly solves when Outsourcing-type of the prior art comes off or splits the fastener locking position that clasp causes because of unbalance stress and lock and operates cumbersome problem, mainly by arranging the balancing of stresses structure that cross section is I-shaped groove in fastener body, the inwall of balancing of stresses structure and fastener is made to form double-layer tube wall structure, and original single side lock locking structure is changed into both sides locking and namely bolt insertion end engaging lug and nut check end engaging lug are set respectively at the two ends of Outsourcing-type fastener body, after steel pipe is inserted into Outsourcing-type fastener, two steel pipes just in time can be clamped in I-shaped groove, carrying out fastening in conjunction with both sides locking mechanism, so just steel pipe is defined well fixing, the potential safety hazard caused because of unbalance stress can be avoided, bolt insertion end engaging lug arranges subsider can conveniently for the locking of steel pipe, use spanner is only needed to tighten nut.
The beneficial effects of the utility model: be that being arranged on of the balancing of stresses structure of I-shaped groove strengthens fixing for steel pipe in conjunction with both sides locking mechanism by cross section; decrease and form the concentrated hidden danger of stress because of unbalance stress; protect whole fastener equipment; decrease the generation of security incident, the setting party of subsider for the locking of fastener.

Detailed description of the invention
In conjunction with the accompanying drawings, the present invention is further detailed explanation, and these accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model and operating principle is described in a schematic manner.
Embodiment 1
See Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, shown in Fig. 6, there is the Outsourcing-type of balancing of stresses structure to clasp, comprise fastener body 1 and the bolt 3 for fixing, nut 5 and pad 4, the two ends of described fastener body 1 arrange two pairs of engaging lugs, be respectively and be provided with the bolt insertion end engaging lug 6 of perforate 8 and the nut check end engaging lug 7 of jaw shape, bolt insertion end engaging lug 6 is provided with and can forms the subsider 9 of interference fit with nuts, described subsider 9 is concentric with perforate 8, the inwall of fastener body 1 is provided with the balancing of stresses structure 2 that cross section is I-shaped groove, described balancing of stresses structure 2 and the inwall of fastener body 1 form double-layer tube wall and the joint being positioned at two steel pipes in fastener body 1 is cut off by I-shaped groove.
Preferably, described subsider 9 is hexagon groove, and corresponding bolt 3 is hex bolts.
The utility model arranges the balancing of stresses structure that cross section is I-shaped groove in fastener body 1, make it to form double-layer tube wall structure with fastener body 1, after two steel pipes insert, steel pipe is just in time clamped in I-shaped groove, and the joint of two steel pipes is separated (as shown in Figure 6) by I-shaped groove, which reduces the interaction between two steel pipes, and adopt both sides locking mechanism, namely steel pipe is locked at the two ends of fastener body 1 after inserting fastener body 1, such structure just alleviates because masterpiece is used in the two ends of steel pipe and the very concentrated problem of the steel pipe joint stress that causes, what alleviate at steel pipe joint is stressed, effectively protect whole fastener equipment, when fastening, bolt 3 forms interference fit between nuts meeting and subsider 9 after being inserted into bolt insertion end engaging lug 6, only needs the nut 5 that screws up with a wrench.
It should be noted that the detailed description of the invention of above just a kind of situation of the utility model; the utility model also can have other embodiment; as adopted key shape subsider and tee T bolt or by other structure of balancing of stresses vibrational power flow; in a word, the structure made under the inspiration of the present embodiment of those skilled in the art or change in fixed form all belong to protection category of the present utility model.
