[0002] Fences are used for the effect of protection and isolation. In construction sites, in order to isolate the construction site, prevent unauthorized personnel from straying in, reduce the probability of safety accidents, and facilitate the efficient progress of construction.

[0003] In a Chinese utility model patent, such as the utility model of CN220336640U, which discloses a construction safety fence and relates to the technical field of fences. The utility model includes a guardrail, and solves the problem that in the prior art, the protection height of an integrally formed fence is fixed and limited. Therefore, in some large-scale construction sites, it is difficult to adapt the fence for use, which reduces the practicability of the fence and also affects the safety protection effect of the fence.

A plug is fixedly installed on the side far away from the slot. The top surface of the base is provided with a guardrail through a plurality of telescopic rods. An extension plate is slidably connected inside the guardrail. Two threaded rods are symmetrically and rotatably connected inside the guardrail, and each threaded rod is threadedly connected to the extension plate.

One end of each rotating shaft is fixedly installed with a clamping seat. A plurality of pins are symmetrically installed on the outside of one of the clamping seats, and a plurality of card slots are symmetrically provided on the outside of the other clamping seat.

[0008] like Figures 1-5 As shown, the specific implementation method is: by setting a slot and a pin, another base can be inserted into the slot through an insert block so that the two bases are first connected, the height of the extension plate can be adjusted through the threaded rod, and the rotating shaft can drive the threaded rod to rotate through the bevel gear connection mechanism, and the two rotating shafts can be locked with each other through the pin and the slot, so that one rotating shaft drives the other rotating shaft to rotate.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The utility model realizes the connection of two bases by arranging slots, pins, plug blocks, card slots, latches, rotating shafts, synchronization mechanisms, bevel gear connecting mechanisms and other devices, and realizes the connection of two bases by inserting the plug blocks in the slots and fixing them by pins.

[0025] Refer to Figures 1-5, A construction operation safety fence, including a base 1. A slot 7 is provided on the side of the base 1. A pin 8 is inserted into the slot 7. A plug 9 is fixedly installed on the side away from the slot 7. The top surface of the base 1 is provided with a guardrail 2 through a plurality of telescopic rods 5. An extension plate 3 is slidably connected inside the guardrail 2. Two threaded rods 10 are symmetrically and rotatably connected inside the guardrail 2, and each threaded rod 10 is threadedly connected to the extension plate 3. The two threaded rods 10 are connected through a synchronization mechanism. Sliding seats 12 are symmetrically and slidably connected inside the guardrail 2, and each sliding seat 12 is rotatably connected to the corresponding threaded rod 10. A rotating shaft 18 is rotatably connected inside each sliding seat 12. Each rotating shaft 18 is connected to the corresponding threaded rod 10 through a bevel gear connection mechanism. A clamping seat 19 is fixedly installed at one end of each rotating shaft 18. A plurality of pins 20 are symmetrically installed on the outside of one clamping seat 19, and a plurality of card slots are symmetrically provided on the outside of the other clamping seat 19.

[0026] As Figures 1-5 shown, the implementation method is specifically as follows: By setting the slot 7 and the pin 8, another base 1 can be inserted into the slot 7 through the plug 9 so that the two bases 1 are first connected. The height of the extension plate 3 can be adjusted by the threaded rod 10. Through the bevel gear connection mechanism, rotating the rotating shaft 18 can drive the threaded rod 10 to rotate. The two rotating shafts 18 can be clamped to each other through the pin 20 and the card slot, so that one rotating shaft 18 drives the other rotating shaft 18 to rotate.

[0027] Each telescopic rod 5 includes an adapter column and a telescopic base, and the adapter column is slidably connected inside the telescopic base. The top end of each adapter column is fixedly connected to the bottom surface of the guardrail 2. A spring 21 is commonly installed between the bottom surface of each adapter column and the bottom wall of the telescopic base. A rubber pad 23 is installed on the bottom surface of each adapter column, and a pressure sensor 22 is installed on the bottom wall of each telescopic base.

[0028] Through the set spring 21, the rubber pad 23 can be driven to reset. At the same time, pressure is applied to the pressure sensor 22 through the rubber pad 23 to determine whether someone climbs over the guardrail.

[0029] The bevel gear connection mechanism includes a second bevel gear 17, and the second bevel gear 17 is installed at the end of the rotating shaft 18 away from the clamping seat 19. A first bevel gear 16 is installed on each threaded rod 10, and each first bevel gear 16 meshes with the corresponding second bevel gear 17.

[0030] Through the meshing of the first bevel gear 16 and the second bevel gear 17, the threaded rod 10 can be driven to rotate by rotating the rotating shaft 18.

[0031] The synchronization mechanism includes two synchronous wheels 14, and each synchronous wheel 14 is installed on the corresponding threaded rod 10. A synchronous belt 15 is commonly sleeved on the plurality of synchronous wheels 14.

[0032] A baffle 13 is fixedly installed inside the guardrail 2, and a square through slot is formed in the baffle 13. Sliding grooves 11 are respectively formed on both sides of the guardrail 2, and each clamping seat 19 is movably connected in the corresponding sliding groove 11.

[0033] Through the square through slot, the rotation of the threaded rod 10 is not affected, and at the same time, the sliding groove 11 provides space for the up and down sliding of the clamping seat 19.

[0034] A plurality of universal wheels 6 are symmetrically installed on the bottom surface of the base 1. A plurality of warning lights 4 are fixedly installed on the outer side of each guardrail 2, and each warning light 4 is electrically connected to the pressure sensor 22.

[0035] When someone climbs over the guardrail 2, the set warning light 4 will give an alarm warning.

[0036] When the utility model is in use, first, the insertion block 9 installed on the outer side of one base 1 is clamped in the slot 7 inside the other base 1 and fixed by the pin 8, so as to realize the connection of the two bases 1. At the same time, the clamping seat 19 installed on one side of the guardrail 2 is aligned with the clamping seat 19 of the other guardrail 2 to be spliced, and the pin 20 is inserted into the corresponding card slot, so as to realize the connection of the rotating shafts 18 of the two guardrails 2. Thus, when one rotating shaft 18 rotates, it can drive the other rotating shaft 18 to rotate;

[0037] Furthermore, when driven by an external driving source, an optional motor drives one of the rotating shafts 18 to rotate. Then, through the meshing of the first bevel gear 16 and the second bevel gear 17, the threaded rod 10 is driven to rotate. Through the setting of the synchronous pulley 14 and the synchronous belt 15, the two threaded rods 10 are driven to rotate synchronously, and then the extension plate 3 is driven to slide upward. At the same time, the second bevel gear 17 and the first bevel gear 16 on the other side drive the rotating shaft 18 on the other side to rotate, and then drive the rotating shaft 18 on the spliced guardrail 2 to rotate. And through the above operations, the extension plate 3 is synchronously slid upward, so as to realize the simultaneous adjustment of a plurality of extension plates 3;

[0038] At the same time, when someone climbs over the guardrail 2, the pressure is transmitted to the telescopic rod 5 through the extension plate 3, and then drives the rubber pad 23 to move downward and act on the pressure sensor 22. Then, the pressure sensor 22 transmits an electrical signal to the warning light 4, and then gives an alarm warning.

[0039] Only some exemplary embodiments of the present utility model are described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present utility model, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present utility model.
