Abstract

The utility model relates to a quick diameter-changing self-locking general building fastener for a scaffold, which comprises a base 1 and a gland 2. The utility model is characterized in that one end of the gland 2 is hinged with the base 1, and the other end of the gland 2 has a U-shaped groove, the external surface of which has curved surface teeth 5; the U-shaped groove end of the gland 2 is locked and connected with a hole of the base 1 via a pull rod 4 and an eccentric distance adjusting shaft 3. The utility model has the advantages of reasonable structure, no need of screwed connection, no bolt and nut and safe and fast use; the utility model can put an end to the randomness of the locking operation of the fastener fundamentally and effectively prevent the safety accident hidden risks of buildings; furthermore, the coefficient of recovery is high, so the utility model can be used repeatedly; the utility model can realize the fast diameter change and the locking to scaffold steel pipes phi 47 M / M to phi 51 M / M.

Description

The quick general building buckle of reducing self-locking

The utility model relates to a kind of building buckle, particularly a kind of general building buckle of quick reducing self-locking that is used for scaffold.

Steel tube scaffold clasp is widely used in engineering constructions such as building construction, tunnel, water conservancy, chemical industry, coal, national defence.At present, the fastening common employing bolt of the building buckle that uses on the construction market, the nut turn is fixed, this fastening means, in case screw thread is damaged, dismounting is difficulty very, even can not use, and engineering construction some months at least, several years at most, expose to the sun and rain for a long time, the dead phenomenon of screw corrosion rust is very serious, and the attached collection of cement mortar finally can cause fastener to disassemble on bolt and nut, and it is extremely low that it reclaims utilization rate; When particularly adopting this fastening means that fastener is loaded onto scaffold, whether fastener really is connected locking with steel pipe, does not have operation or work standard to follow, and relies on operating personnel's experience or sensation fully, and regular meeting stays building safety accident potential thus.

That the purpose of this utility model is to provide is a kind of rational in infrastructure, safe in utilization, the general building buckle of reducing self-locking fast efficiently.

The utility model is achieved in that the general building buckle of a kind of quick reducing self-locking, and it comprises pedestal, and gland is characterized in that: an end and the pedestal of gland are hinged, and the other end of gland is provided with U type groove, is provided with the curved surface tooth at the external surface of U type groove; The U type groove end of gland is connected locking with the aperture pull bar of pedestal with eccentric roll adjustment axle.

Above-mentioned pull bar is a T type pull bar, the axle tooth that T type pull bar top has the curved surface tooth with gland U type groove to be complementary, and the hole inner surface of T type pull bar is provided with platform; Above-mentioned eccentric roll adjustment axle one side of passing T type pull bar hole is fluted, and one side is established platform, and also is provided with salient point on the eccentric roll adjustment axle, the locking that is complementary of the embedding mouth of the Kong Shangshe of this salient point and pedestal.

In sum, the utility model adopts overall structure, connect without screw, the non-bolt nut, therefore, be not afraid of cement mortar and the corrosion rust that exposes to the sun and rain dead, can 100% reclaim and be repeatedly used; Because design has to design on curved surface tooth and the pull bar on the gland of fastener a tooth is arranged, can realize scaffolding steel pipe Φ 47M/M-quick reducing of Φ 51M/M and locking; The utility model biggest advantage is that also its profit has eccentric roll adjustment axle principle to reach automatic contraposition locking, randomness when fundamentally having stopped the fastener locking operation, effectively prevented building safety accident potential, and the utility model has kept the basic profile of conventional fastener, realize and solved fastener production unifying the universal standardization problem, do not need spanner during operation, hammer beats, only pull, just can mount and dismount rapidly several seconds.

The utility model is described in further detail below in conjunction with drawings and Examples:

Fig. 1: the structural representation of the utility model embodiment 1;

Fig. 2: the front view that is pull bar among Fig. 1;

Fig. 3: the vertical view that is Fig. 2;

Fig. 4: the front view that is eccentric roll adjustment axle among Fig. 1;

Fig. 5: the vertical view that is Fig. 4;

Fig. 6: the A-A sectional view that is Fig. 4.

Referring to Fig. 1 as can be known: present embodiment is to be that the utility model is described in further detail for example with the right-angle coupler, the general building buckle of a kind of quick reducing self-locking, it comprises pedestal 1, gland 2, it is characterized in that: an end and the pedestal 1 of gland 2 are hinged, the other end of gland 2 is provided with U type groove, is provided with curved surface tooth 5 at the external surface of U type groove; The U type groove end of gland 2 is connected locking with the aperture pull bar 4 of pedestal 1 with eccentric roll adjustment axle 3.

Referring to Fig. 1 and 2～3 as can be known: pull bar 4 is a T type pull bar among the figure, the axle tooth 6 that T type pull bar top has the curved surface tooth 5 with gland 2U type groove to be complementary, and the hole inner surface of T type pull bar is provided with platform 7.

Referring to Fig. 1 and 4～6 as can be known: eccentric roll adjustment axle 3 one sides are fluted 8 among the figure, and one side is established platform 9, and also is provided with salient point 10 on the eccentric roll adjustment axle 3, the locking that is complementary of the embedding mouth 11 of this salient point 10 and the Kong Shangshe of pedestal 1.

Structure described in the utility model is equally applicable to rotary buckle and to clasp.
