Abstract
The utility model discloses an outer clamping dropping-prevention pin which comprises a pin and an outer clamping spring ring which is arranged to be Omega-shaped. The outer clamping spring ring, close to two end heads, is respectively bent towards two outer side directions to be a shape with a 6cm radius R, the two end heads of the outer clamping spring ring are circular-arc-shaped, the radius R of a fillet is equal to 6cm, the lower end of the pin is arranged to be a chamfer, and the chamfer is equal to 2*45 degrees. The outer clamping dropping-prevention pin has the advantages that the outer clamping dropping-prevention pin is composed of the pin and the outer clamping spring ring, elasticity and a bending shape of the outer clamping spring ring are utilized to enable the pin to achieve dropping-prevention reliable connection and achieve rapid connection and dismantling effect.
Description
Technical field
The utility model relates to a kind of engineering scaffold, supporting frame, particularly a kind of wild card anti-avulsion pin.
Background technique
Dish pin formula supporting frame is in recent years from the domestic a kind of novel support system of external introducing.Supporting frame vertical rod and vertical rod are located by connecting and realize by pitman (pipe).For safety and supporting frame integral hoisting, need to be located by connecting with pitman and prevent from coming off in vertical rod and vertical rod joint.For rapid construction, need to accomplish the pin of pitman can locate fast, reliably connect (preventing from coming off), simultaneously again can quick-detachment.
The model utility content
Technical problem to be solved in the utility model provides a kind of wild card anti-avulsion pin.
For solving the problems of the technologies described above, the utility model is realized as follows: a kind of wild card anti-avulsion pin comprises pin and wild card spring ring; Described wild card spring ring is arranged to Ω shape shape, and is bent into respectively the shape of radius R=6cm to two lateral direction in the position near two ends; The two ends of described wild card spring ring is set to circular shape, fillet radius R=6cm; The lower end of described pin is set to chamfering=2 * 45 °.
Good effect of the present utility model is: described wild card anti-avulsion pin, formed by special pin and wild card spring ring, and utilize the elasticity of wild card spring ring and the shape that bends, pin is reached prevent from coming off reliable the connection, and can reach the effect of quick connection and dismounting.

Fig. 2 is wild card anti-avulsion pin side view
Fig. 3 is the local enlarged diagram of the pin in the wild card anti-avulsion pin assemblies.
Fig. 4 is wild card anti-avulsion pin and pitman, vertical rod connection diagram.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
As shown in Figure 1, a kind of wild card anti-avulsion pin described in the utility model is an assembly, comprises pin 1 and wild card spring ring 2.Wild card spring ring 2 is arranged to Ω shape shape, and is bent into respectively the shape of radius R=6cm to two lateral direction in the position near two ends.
As shown in Figure 2, the two ends of wild card spring ring 2 is set to circular shape, fillet radius R=6cm.The lower end of pin 1 is set to chamfering=2 * 45 °.
As shown in Figure 3, Fig. 3 is the pin partial enlarged drawing, and is indeformable for the ease of riveting rear wild card spring ring 2, and the junction of pin 1 upper end riveted joint and pin 1 body is designed to spherical form (R sphere).
Fig. 4 is seen in practical application, directly wild card anti-avulsion pin is penetrated in the pore of vertical rod 3 and pitman 4 in the preassembly; During dismounting, only wild card spring ring (R6) need be broken a little into two with one's hands, whole anti-avulsion pin can be extracted.
The beneficial effects of the utility model:
Described wild card anti-avulsion pin is comprised of special pin and wild card spring ring, utilizes the elasticity of wild card spring ring and the shape that bends, and pin is reached prevent from coming off reliable the connection, and can reach the effect of quick connection and dismounting.
The utility model is intended to improve the pin on the pitman, be designed to a kind of can be convenient, fast and prevent the pin assemblies of the reliable connection that comes off.
The utlity model has following advantage: (1) can fast quick-mounting, tear open; (2) prevent that reliably pin from coming off; (3) through zinc-plated processing, can repeatedly use for a long time.
Claims (2)
1. a wild card anti-avulsion pin is characterized in that, comprises pin and wild card spring ring; Described wild card spring ring is arranged to Ω shape shape, and is bent into respectively the shape of radius R=6cm to two lateral direction in the position near two ends; The two ends of described wild card spring ring is set to circular shape, fillet radius R=6cm; The lower end of described pin is set to chamfering=2 * 45 °.
2. wild card anti-avulsion pin according to claim 1 is characterized in that, the junction of described pin upper end riveted joint and described pin body is designed to spherical form.
