Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
embodiment one, as shown in fig. 1 to 7, in this embodiment, a lighthouse mast self-locking device includes
The frame 100 is provided with two parallel side plates 110 and a connecting plate 120 connected to the two side plates 110, and the corresponding positions of the two side plates 110 are respectively provided with a long-strip-shaped limiting hole 111 extending along the moving direction of the frame 100;
Two positioning plates 130, respectively disposed on the two side plates 110;
A pulley shaft 210 penetrating the two limiting holes 111 and capable of reciprocating in the limiting holes 111 along the moving direction of the frame 100;
A pulley 200 disposed on the pulley shaft 210, and the pulley 220 is located between the two side plates 110;
Two springs 240, one end of each of the two springs 240 is connected to a portion of the pulley shaft 210 extending out of the position-limiting hole 111, the other end of each of the two springs 240 is connected to the two positioning plates 130, and the springs 240 are used for applying a pulling force to the pulley shaft 210, the pulling force being directed to the positioning plates 130;
a positioning shaft 310 disposed on the two side plates 110 and penetrating the two side plates 110, wherein the positioning shaft 310 is located at an end of the side plate 110 far away from the positioning plate 130;
a pulling plate 320, disposed on the positioning shaft 310 and outside between the two side plates 110, wherein the pulling plate 320 can rotate on a plane parallel to the plane of the side plates 110, the pulling plate 320 extends to an end away from the positioning shaft 310 and protrudes from the side plates 110, and the portion of the pulling plate 320 protruding from the side plates 110 is used for blocking the movement of the frame 100 after the steel cable 420 is broken;
A waist hole 321, the shifting plate 320 is provided with a waist hole 321 with the same size as the limiting hole 111, the waist hole 321 is inclined relative to the limiting hole 111, and the pulley shaft 310 passes through the waist hole.
In this embodiment, when the steel cable 420 is not broken, the steel cable 420 applies a pulling force to the pulley 220, the pulling force applied by the steel cable 420 is greater than the pulling force of the spring 240, the pulley shaft 210 moves in the position-limiting hole 111 to the end farthest from the positioning plate 130, and since the pulley shaft 210 penetrates through the waist hole 321 and the waist hole 321 is inclined with respect to the position-limiting hole 111, the pulley shaft 210 moves in the waist hole 321 to the end close to the positioning shaft 310 and drives the dial 320 to rotate along the direction b until the portion of the dial 320 protruding from the side plate 110 does not contact with the position-limiting plate 410, so that the frame 100 can move normally;
