The wire fixing fork 200 adopts a structure surrounded by three plates, so that the manufacturing cost can be reduced, the horizontal rotating shaft 240 is perpendicular to the length direction of the locking pin 250, the locking pin 250 can rotate in a plane perpendicular to the first side plate 220, and when the locking pin 250 rotates to be in contact with the first side plate 220, the opening of the fixing fork can be closed. The locking pin 250 can be directly pushed when the slider moves from bottom to top.
Referring to fig. 4 and 5, a first notch 221 is vertically disposed on the first side plate 220 at a position corresponding to the locking pin 250, a second notch 231 for accommodating the locking pin 250 is vertically disposed on the second side plate 230, and a blocking protrusion 232 extending to the other side is further disposed on one side of the upper edge of the second notch 231. The second notch 231 and the first notch 221 may allow the locking pin 250 to be fixed by the second notch 231 when being rotated to the second side plate 230, and the first notch 221 may allow the locking pin 250 to be balanced when being locked into the second notch 231. The blocking protrusion 232 is used for preventing the lifeline from being forced to lift the locking pin 250, when the lifeline is forced to push the locking pin 250 outwards, the locking pin 250 is pushed under the blocking protrusion 232, that is, a space for limiting the locking pin 250 is formed between the blocking protrusion 232 and the bottom of the second notch 231, and the locking pin 250 cannot be turned upwards to unlock due to the blocking protrusion 232. In order that the blocking protrusion 232 does not affect the normal opening of the locking pin 250, the distance between the blocking protrusion 232 and the other side of the second notch 231 is slightly larger than the thickness of the locking pin 250, so that the locking pin 250 can be normally locked into and disengaged from the second notch 231.
Referring to fig. 2 and 3, the mounting base 100 includes a horizontal plate 110, a bending portion 120 is vertically disposed at one end of the horizontal plate 110 near the wire fixing fork 200, the mounting base 100 is fixedly connected to the bottom plate 210 of the wire fixing fork 200 through the bending portion 120, and the bending portion 120 and the bottom plate 210 are fixedly connected through a second bolt 400. The bending part 120 can be attached to the floor in a large area, and the reliability of connection is increased.
The horizontal rotation shaft 240 is fixed at a position corresponding to the first notch 221 outside the first side plate 220. During manufacturing, the horizontal rotating shaft 240 may be directly fixed on the first side plate 220 by welding, and the locking pin 250 is rotatably disposed on the horizontal rotating shaft 240 through a shaft hole. The locking pin 250 can be smoothly locked into the first notch 221 and the second notch 231 after being connected by the horizontal rotating shaft 240.
Referring to fig. 4 and 5, a limiting protrusion 251 is further extended on the side of the locking pin 250 connected to the horizontal rotating shaft 240. The limiting projection 251 is used for limiting the upward turning angle of the locking pin 250, so as to prevent the locking pin 250 from falling to the second side plate 230 after the sliding block passes through. When the locking pin 250 is separated from the second notch 231 and turned upwards, the distance between the limit lug 251 and the first side plate 220 is reduced along with the increase of the rising height of the locking pin 250, the locking pin 250 cannot be turned further when the limit lug 251 is in contact with the first side plate 220, at this time, the sliding block can smoothly pass through the wire fixing fork 200, and the gravity center of the locking pin 250 is still located between the planes of the first side plate 220 and the second side plate 230, so that the sliding block can fall under the action of self gravity through the rear locking pin 250 and be blocked into the second notch 231 again.
In order to increase the reliability of the locking pin 250 falling back to the second notch 231, a torsion spring is provided at a position where the horizontal rotation shaft 240 is connected with the locking pin 250 to assist in resetting the locking pin 250.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present invention, and not for limiting the same; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the invention, and are intended to be included within the scope of the appended claims and description.
