The server provided in the embodiment of the present application is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.

Embodiment 1:

As shown in Figures 1 to 3, an embodiment of the present application provides an anti-fall device for a stacker truck, including a frame 1 and a lifting frame 2, and also includes a fixed frame 3, which is fixed to the frame 1; a flip rod 4, which can be movably mounted on the fixed frame 3 through a connecting mechanism 5, and one end of the flip rod 4 can extend under the lifting frame 2.

Furthermore, the connecting mechanism 5 includes a hinge shaft 51, which is rotatably inserted in the middle of the fixing frame 3 and the flip rod 4; a fixing block 52, which is fixed to one end of the hinge shaft 51; and a nut 53, which is installed on the other end of the hinge shaft 51 through a thread.

Furthermore, the connecting mechanism 5 further includes a bearing 54 , which is used to enable the hinge shaft 51 to rotatably cooperate with the fixing frame 3 ; and a clamping member 6 , which is used to fix the hinge shaft 51 to the middle part of the flip rod 4 .

Furthermore, the engaging member 6 includes a plurality of slots 61 which are arranged at intervals on the flip rod 4 ; and a plurality of blocks 62 which are fixedly connected to the hinge shaft 51 at intervals along the circumferential direction and are plugged and matched with the corresponding slots 61 .

Furthermore, the connecting mechanism 5 also includes an outer limiting groove 55, which is arranged on the inner circumferential wall of the nut 53; an inner limiting groove 56, which is arranged on the circumferential wall of the hinge shaft 51 away from the fixed block 52; and an insertion rod 57, which can be inserted into the outer limiting groove 55 and the inner limiting groove 56.

In this embodiment of the present application, due to the adoption of the above-mentioned structure, when the lifting frame 2 is lowered carrying heavy goods, the worker controls the turning rod 4 and the hinge shaft 51 to rotate so that one end of the turning rod 4 extends to the bottom of the lifting frame 2. When the lifting frame 2 is close to the turning rod 4, it has been lowered to a safe height. At this time, the turning rod 4 and the hinge shaft 51 are controlled to rotate so that the turning rod 4 is away from the bottom of the lifting frame 2. The bearing 54 can reduce the friction between the hinge shaft 51 and the fixed frame 3. The engaging member 6 can keep the relative positions of the hinge shaft 51 and the turning rod 4 consistent during the rotation process without friction, which can effectively reduce the loss caused by friction between the components. The cooperation of the insertion rod 57 with the outer limiting groove 55 and the inner limiting groove 56 can prevent the nut 53 from falling off from the end of the hinge shaft 51, thereby ensuring the stable connection between the turning rod 4 and the fixed frame 3.

The fixing frame 3 is fixed to the lower part of the frame 1 by bolts.

Embodiment 2:

As shown in Figures 2 and 3, in addition to the structural features of the aforementioned embodiments, this embodiment also includes a pair of slots 7, which are arranged on the surface of the fixing frame 3; a plug-in component 8, which is telescopically installed at one end of the flip rod 4 and can be inserted into the corresponding slot 7, and the pair of slots 7 are respectively located below the connecting mechanism 5 and away from the left side of the lifting frame 2.

Furthermore, the plug-in component 8 includes a sliding hole 81 , which is arranged on the flip rod 4 ; a sliding rod 82 , which is slidably inserted in the sliding hole 81 , one end of which is fixedly connected to the pull plate 84 , and the other end of which can be inserted into the slot 7 .

Furthermore, the connector 8 also includes a plurality of limiting ring grooves 83 which are spaced apart on the slide rod 82 ; and a plurality of floating limiting units 9 which are movably mounted in the slide hole 81 and are used to cooperate with the corresponding limiting ring grooves 83 to limit the position of the slide rod 82 in the slide hole 81 .

Preferably, a plurality of floating restriction units 9 are arranged at intervals along the circumferential direction.

Furthermore, the floating limiting unit 9 includes a blind hole 91 , which is arranged in the sliding hole 81 ; a floating steel ball 92 , which is movably installed in the blind hole 91 through a floating spring 93 , and the outer end of the floating steel ball 92 can be inserted into the corresponding limiting ring groove 83 .

In this embodiment of the present application, due to the adoption of the above-mentioned structure, when it is necessary to rotate the flip rod 4 around the hinge shaft 51, the sliding rod 82 is pulled in the direction away from the fixed plate through the pull plate 84, and each floating steel ball 92 disengages from the current limiting ring groove 83, and the corresponding floating spring 93 is compressed and shortened until the end of the sliding rod 82 disengages from the corresponding slot 7, and each floating steel ball 92 moves to correspond to another limiting ring groove 83. At this time, under the action of each floating spring 93, the outer end of each floating steel ball 92 enters the limiting ring groove 83. Conversely, when it is necessary to fix the position of the flip rod 4, the pull plate 84 is pressed to insert the other end of the sliding rod 82 into the corresponding slot 7, and each floating steel ball 92 disengages from the current limiting ring groove 83, and the corresponding floating spring 93 is compressed and shortened until the end of the sliding rod 82 is inserted into the corresponding slot 7, and each floating steel ball 92 moves to correspond to another limiting ring groove 83. At this time, under the action of each floating spring 93, the outer end of each floating steel ball 92 enters the limiting ring groove 83.
