Above-mentioned closed strainer, described swing arm are provided with the insurance pin-and-hole that matches with strainer insurance pin-and-hole.

Above-mentioned closed strainer, described strainer rotating cylinder both ends are provided with the locking baffle plate that matches with swing arm.

Above-mentioned closed strainer, described two swing arm ends adopt the reducing connection to revolve ring, revolve ring and are connected with cargo hook.

The advantage of the closed strainer of the utility model is: the movable handle of this strainer adopts and closed rotating cylinder separation type design, solved the problem that is subjected to the operational space restriction in the past cleverly, and this mechanism's dexterity, convenience can freely realize the instant tension of object and unclamp that safety plug that is provided with on closed rotating cylinder and the swing arm and locking baffle plate have improved the safety factor of this closed strainer greatly.

Description of drawings

Below in conjunction with drawings and the specific embodiments the utility model is described in further detail.

Fig. 1 is the structural representation of the closed strainer of the utility model;

Fig. 2 is the semisectional view of the closed rotating cylinder of the closed strainer of the utility model;

Fig. 3 is the closed strainer swing arm of a utility model structural representation;

Fig. 4 is a locking baffle arrangement enlarged drawing of the present utility model.

The specific embodiment

As shown in Figure 1, 2, a kind of closed strainer comprises strainer rotating cylinder 1 and is arranged on the swing arm 3 at two ends, and strainer rotating cylinder 1 center outside face is provided with to be pulled mouthful 10 rotating cylinders that match with free handle and pull mouthfuls 8, and rotating cylinder is pulled mouthful 8 both sides and is provided with insurance pin-and-hole 9.Free handle 6 adopts the separation type setting with strainer rotating cylinder 1.

As shown in Figure 3, it is the swing arm constructional drawing, two swing arms, 3 ends adopt the reducing connection to revolve ring, promptly adopt the pyriform ring, pyriform is bad to be connected with cargo hook 4 by pin 5, be processed with the insurance pin-and-hole 10 that is used to place safety plug in the end of swing arm 3, the other end is made the pyriform ring structure, and this structure can reduce the stress concentration that Yin Lali produces to the full extent.

As shown in Figure 4, be locking baffle plate 2 constructionals drawing, with swing arm 3 by being threaded, be installed in the two ends of strainer rotating cylinder 1, this locking baffle plate 2 can be in swing arm 3 screws in strainer rotating cylinders 1, promptly strain goods after, screw locking baffle plate 2, be used to prevent the excessive thread failure that causes of Yin Lali, safety misadventure takes place.

This closed strainer, the rotating cylinder of strainer rotating cylinder 1 are pulled mouth 8 and are shaped on equidistant indent rectangular opening, and the mouth of pulling of free handle 6 is shaped on the semi-circular cross-section structure that matches with the indent rectangular opening.

The inboard surface of revolution in these strainer rotating cylinder 1 both ends is provided with screw thread, and the swing arm 3 outer surfaces of revolution are provided with the screw thread that matches with strainer rotating cylinder 1.Swing arm 3 is provided with the insurance pin-and-hole 10 that matches with strainer rotating cylinder 1 insurance pin-and-hole 9, when swing arm 3 screws in the strainer rotating cylinder 1, in the insurance pin-and-hole 9 of strainer rotating cylinder 1, put into the insurance pin-and-hole 10 that passes simultaneously on the swing arm 3 respectively with the taper pin that matches with pin-and-hole 9, can avoid like this user in the process of using because the unexpected injury that the work strain or the inefficacy that is threaded cause.
