[0064] Refer to Figure 5 , 6 The hinged component 82 comprises two groups of circular plates 821 fixedly connected in the mounting box 81, an arc-shaped groove 822 opened in the circular plate 821, a second sliding rail 823 fixedly connected to the arc-shaped groove 822, a clamping block 824 slidingly connected to the arc-shaped groove 822, a tooth groove 825 opened in the inner side of the clamping block 824, a second shaft 826 fixedly connected between the upper and lower two groups of circular plates 821, a first gear 827 rotationally connected to the second shaft 826, a third shaft 828 fixedly connected between the upper and lower two groups of circular plates 821, a second gear 829 rotationally connected to the third shaft 828, the second gear 829 is engaged with the first gear 827, and the second gear 829 and the first gear 827 are engaged with the tooth groove 825 in the inner side of the clamping block 824, a third gear 8210 rotationally connected to the third shaft 828, the third shaft 828 extends out of the upper circular plate 821, a mounting frame 8211 fixedly connected to the upper circular plate 821, a fourth shaft 8212 rotationally connected to the mounting frame 8211, a worm 8213 fixedly connected to the fourth shaft 8212, wherein the worm 8213 on the upper side of the connecting frame 2 is in the opposite direction of the thread on the worm 8213 on the lower side of the connecting frame 2, and a first bevel gear 8214 fixedly connected to the fourth shaft 8212.

[0065] Specifically, when the right side of the enclosure 4 is installed on the connecting frame 2, the right side of the second group of mounting frames 8211 is connected with the left side of the enclosure 4, and the long shaft 5 is placed between the circular plates 821.

[0066] In use, the clamping block 824 is in an open state in the initial state, and when the right side of the enclosure 4 is installed, only the second group of mounting frames 713 is moved to the left side of the enclosure 4, and then the long shaft 5 on the enclosure 4 is placed between the circular plates 821 on the upper and lower hinge units 8.

[0067] Only the second group of mounting frames 713 is moved to the left side of the enclosure 4, and then the long shaft on the enclosure 4 is placed between the circular plates 821 on the upper and lower hinge units 8, and the installation of the left side of the enclosure 4 is completed.

[0068] The remaining structure is the same as that of Example 1.

[0069] Example 3, refer to Figures 1-8 , the third embodiment of the present application, which is different from the second embodiment is: the control unit 9 includes a circular groove 91 arranged in the middle of the connecting frame 2, a transmission rod 92 arranged in the connecting frame 2, and a control component 93 arranged on the connecting frame 2.

[0070] Refer to Figures 6-8 , the control component 93 includes a second bevel gear 931 rotatably connected to the circular groove 91, a square hole 932 opened on the outside of the second bevel gear 931, a wrench 933 inserted into the square hole 932, a third bevel gear 934 fixedly connected to the transmission rod 92, the second bevel gear 931 and the third bevel gear 934 are engaged, a fourth gear 935 fixedly connected to the middle of the transmission rod 92, a blocking plate 936 fixedly connected to the outside of the connecting rod 733, a telescopic shell 937 fixedly connected to the blocking plate 936, a third spring 938 installed in the telescopic shell 937, a toothed plate 939 slidingly connected in the telescopic shell 937, the toothed plate 939 and the fourth gear 935 are engaged, and a fourth bevel gear 9310 fixedly connected to the top of the transmission rod 92, and the fourth bevel gear 9310 and the first bevel gear 8214 are engaged.

[0071] Specifically, when the long shaft 5 on the enclosure 4 is placed on the circular plate 821, the clamping block 824 is in an open state and does not clamp the long shaft 5, so the wrench 933 needs to be inserted into the square hole 932 and then turned counterclockwise. At this time, the second bevel gear 931 drives the transmission rod 92 to rotate clockwise, and the fourth bevel gear 9310 at the top of the transmission rod 92 also drives the first bevel gear 8214 above the connecting frame 2 to rotate clockwise, thereby driving the fourth shaft 8212 to rotate clockwise. Since the threads on the worms 8213 at the upper and lower ends of the connecting frame 2 are arranged in opposite directions, the worms 8213 drive the third gears 8210 at the upper and lower ends to rotate clockwise, thereby driving the first gear 827 and the second gear 829 to rotate in opposite directions, and thus the clamping plate 716 is folded to clamp the long shaft 5.

[0072] During use, when the left side of the enclosure 4 needs to be connected to the connecting frame 2, the long shaft 5 on the left side of the enclosure 4 is placed between the circular plates 821. At this time, the clamping block 824 is in an open state and does not clamp the long shaft 5, so the wrench 933 needs to be inserted into the square hole 932 and then turned counterclockwise. At this time, the second bevel gear 931 drives the transmission rod 92 to rotate clockwise, and the fourth bevel gear 9310 at the top of the transmission rod 92 also drives the first bevel gear 8214 above the connecting frame 2 to rotate clockwise, thereby driving the fourth shaft 8212 to rotate clockwise. Since the threads on the worms 8213 at the upper and lower ends of the connecting frame 2 are arranged in opposite directions, the worms 8213 drive the third gears 8210 at the upper and lower ends to rotate clockwise, thereby driving the first gear 827 and the second gear 829 to rotate in opposite directions, and thus the clamping plate 716 is folded to clamp the long shaft 5. When the wrench 933 is turned counterclockwise, the toothed plate 939 will continuously extend out of the telescopic shell 937 under the drive of the fourth gear 935, and then be pulled back by the third spring 938, so it will not affect the normal rotation of the transmission rod 92. When the enclosure 4 needs to be disassembled, the wrench 933 can be turned clockwise, and the toothed plate 939 will be driven to move outward, thereby driving the connecting rod 733 to move outward. In this process, the limiting block 732 first releases the limiting of the sliding plate 721, and then the clamping block 824 is released from clamping the long shaft 5 by continuing to turn clockwise. During the continuous turning process, the outermost teeth of the toothed plate 939 will continuously abut against the fourth gear 935, so it will not affect the normal rotation of the transmission rod 92.

[0073] By turning the wrench 933 counterclockwise, the clamping block 824 can complete the clamping and fixing of the left side of the enclosure 4. By turning the wrench 933 clockwise, the clamping plate 716 and the clamping block 824 can simultaneously release the clamping and fixing of the enclosure 4, which is quick and simple to operate.

[0074] The remaining structure is the same as that in Example 2.

[0075] Example 4, refer to Figures 1-8 The fourth embodiment of the present invention provides a method for using a safety enclosure device for a construction area, comprising the following steps:

[0076] S1: First, align the short shaft 6 on the right side of the enclosure 4 with the arc plate 711, so that the bottom of the short shaft 6 is placed on the base 712. At this time, the clamping plate 716 will automatically open to both sides. Then push the enclosure 4 so that the short shaft 6 enters the rectangular slide groove 33. At this time, the clamping plate 716 will close, and the limiting block 732 will limit and fix the slide plate 721. At this time, the right side of the enclosure 4 is installed with the connecting frame 2.

[0077] S2: Then move the second set of connecting frames 2 so that the long shaft 5 on the surrounding plate 4 is placed on the circular plate 821 on the connecting frame 2. At this time, the clamping block 824 is in the open state, that is, the initial state.

[0078] S3: Then, insert the wrench 933 into the square hole 932 and rotate the wrench 933 counterclockwise. At this time, under the action of the transmission rod 92, the clamp 824 will close accordingly until it is rotated to the point where it encounters resistance and cannot rotate. At this time, the clamp 824 has completed the clamping of the long shaft 5. Then, repeat the above three actions to complete the installation of multiple sets of enclosure plates 4. When rotating the wrench 933 counterclockwise, since the toothed plate 939 and the telescopic shell 937 are connected by the third spring 938, under the transmission of the fourth gear 935, the toothed plate 939 will continuously extend out of the telescopic shell 937 and then be pulled back by the action of the third spring 938. Therefore, it will not affect the normal rotation of the transmission rod 92.

[0079] S4: Finally, if it is necessary to disassemble the enclosure 4, the wrench 933 can be inserted into the square hole 932 and the wrench 933 can be turned clockwise. At this time, under the transmission action of the transmission rod 92, the clamping block 824 and the clamping plate 716 will release the clamping of the long shaft 5 and the short shaft 6 on the enclosure 4, and it can be easily disassembled. When disassembling the enclosure 4 by turning the wrench 933 clockwise, the toothed plate 939 will be driven to move outward, thereby driving the connecting rod 733 to move outward. During this process, the limiting block 732 first releases the limiting of the slide plate 721, and then continues to rotate clockwise to allow the clamping block 824 to release the clamping of the long shaft 5. During the continued rotation, the teeth of the toothed plate 939 at the end away from the blocking plate 936 will continuously abut against the fourth gear 935, so it will not affect the normal rotation of the transmission rod 92.
