Abstract
The utility model discloses a rotary fastener for building scaffolds, which comprises a forged male fastener and a forged female fastener which can mutually rotate, one side of each of the two fastener is riveted together, wherein the center of a fixing piece of the male fastener is provided with a semi-circular big slot which is provided without a pin hole, and the reverse surface of the big slot is provided with a salience which can be inserted into a pin hole of the female fastener. The center of the fixing piece of the female fastener is also provided with a semi-circular big slot, and a pin hole is vertically arranged in the semi-circular big slot. The male fastener is an entire with the structure and is inserted into the female fastener, the male fastener is riveted with one side of the female fastener and is a forged piece, so strength is greatly increased.
Description
Technical field
The utility model belongs to the turn buckle in the building field scaffold connection fastener.
Background technology
Turn buckle in the existing building field scaffold connection fastener is all identically formed through two limit riveteds by the single fastener that is made of the fixture of pin hole and the movable part be made up of semicircle arc cover plate and bolt, nut respectively by two, and all be to adopt cast member, this turn buckle insufficient strength, even the frame that can collapse, cause personnel's injures and deaths.
The utility model content
The purpose of this utility model is to provide a kind of intensity height, and the scaffold that skid resistance is strong connects turn buckle.
This turn buckle comprises that respectively two single fastener riveteds that are made of fixture and the movable part be made up of semicircle arc cover plate and bolt, nut form, it is characterized in that it is to be formed at mother buckle one side riveted by a pin thread spare and a mother buckle, and can rotate mutually; Wherein there is a semicircle arc big groove in the fixture central authorities of pin thread spare, no pin hole in the groove, reverse side at big groove has the projection that can insert in the mother buckle pin hole, also there is a semicircle arc big groove in the fixture central authorities of mother buckle, in this big groove and with its vertical direction a pin hole are arranged.
Fixture two ends of male and female fastener connect semicircle arc cover plate and the bolt that has the claw type breach, nut respectively by pin; The semicircle arc cover plate that has the claw type breach can be connected with the bolt of another side by nut, and with fixture in semi-circular recesses synthesize a fixedly circle of steel pipe.Loosen nut is their connection of disassemble easily then; When two single fasteners are rotated in mutually perpendicular direction, just two mutually perpendicular steel pipes can be fixed, also can the steel pipe of different angles be fixed according to different needs.With upper fastener is to form through forging and pressing.
The fastener of this a kind of structure, because pin thread spare is an integral body, and by inserting in the mother buckle again at mother buckle one side riveted, so the intensity of this fastener improves greatly, this fastener is a press forging, intensity than cast member commonly used improves again greatly, so but this fastener is solid, intensity is high, light weight, economical with materials also.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is pin thread spare and mother buckle coupling part cut-away view.
The specific embodiment:
In conjunction with the accompanying drawings: this turn buckle is to be formed at mother buckle one side riveted by a pin thread spare 1 and a mother buckle 2 that is formed by forging and pressing, and can rotate mutually; Wherein there is a semicircle arc big groove 9 in the fixture central authorities of pin thread spare, no pin hole in the groove, reverse side at big groove has the projection 8 that can insert in the mother buckle pin hole, also there is a semicircle arc big groove in the fixture central authorities of mother buckle, hole 4 movable parts that have a projection that can allow pin thread spare 8 insert in this big groove and with its vertical direction and carry out riveted comprise the semicircle arc cover plate 3 that has the claw type breach, and bolt 6, nut 7; The semicircle arc cover plate 3 that has the claw type breach can be connected with the bolt 6 of another side by nut 7, and with fixture in semi-circular recesses synthesize a fixedly circle of steel pipe, loosen nut is their connection of disassemble easily then; When two single fasteners are rotated in mutually perpendicular direction, just two mutually perpendicular steel pipes can be fixed, also can the steel pipe of different angles be fixed according to different needs.
Claims (2)
