[0028] As Figure 1 and Figure 3 As shown in FIGS. and, an edge protection device 100 provided by an embodiment of the present utility model includes a plurality of vertically arranged upright rods 1 arranged at intervals, and at least one length-adjustable cross bar 2 is provided between every two adjacent upright rods 1. The cross bars 2 are respectively connected to the corresponding two upright rods 1; an insertion plate 13 is sleeved on each of the upright rods 1, and a plurality of insertion holes 131 are circumferentially arranged at intervals on the insertion plate 13. Plug heads 23 are provided at both ends of the cross bar 2, and the plug heads 23 are selectively inserted into any one of the insertion holes 131 corresponding to the insertion plate 13.

[0029] In the present utility model, the edge protection device 100 includes a plurality of vertically arranged upright rods 1 arranged at intervals, and at least one length-adjustable cross bar 2 is provided between every two adjacent upright rods 1. An insertion plate 13 is sleeved on each of the upright rods 1, and a plurality of insertion holes 131 are circumferentially arranged at intervals on the insertion plate 13. Plug heads 23 are provided at both ends of the cross bar 2, and the plug heads 23 are selectively inserted into any one of the insertion holes 131 corresponding to the insertion plate 13. By selectively inserting the two plug heads 23 of the cross bar 2 into any one of the insertion holes 131 corresponding to the insertion plate 13, the enclosure angle between different cross bars 2 can be adjusted. Combined with the length-adjustable cross bar 2, it can adapt to the irregularly shaped edge area, and has good versatility.

[0030] It should be noted that the number of the cross bars 2 is not specifically limited, and a plurality of cross bars 2 can be provided. In this way, a plurality of cross bars 2 can be installed on the same insertion plate 13, so that a plurality of protection areas can be divided by the installation and arrangement of the plurality of upright rods 1 and the plurality of cross bars 2. Preferably, the cross section of the insertion plate 13 is in the shape of a plum blossom.

[0031] Specifically, please refer to Figure 1 In some embodiments, the cross bar 2 includes a connecting sleeve 25 and two connecting rod segments 21. A plurality of through holes 26 penetrating radially through the connecting sleeve 25 are provided on the connecting sleeve 25, and the through holes 26 are arranged at intervals along the axial direction of the connecting sleeve 25. The two connecting rod segments 21 are selectively connected to any one of the through holes 26 at both ends of the connecting sleeve 25 by bolts, and the plug heads 23 are respectively provided at the ends of the two connecting rod segments 21 far away from the connecting sleeve 25. After inserting the two connecting rod segments 21 into the connecting sleeve 25, the corresponding through holes 26 are selected according to the length of the cross bar 2 to be adjusted and connected by bolts, realizing the length adjustment of the cross bar 2 and improving the versatility of the edge protection device 100.

[0032] Specifically, please refer to Figure 2, in some embodiments, the cross bar 2 includes an adjusting sleeve 22 and two connecting rod segments 21. The two connecting rod segments 21 are respectively threadedly connected to both ends of the adjusting sleeve 22, and the plugs 23 are respectively provided at the ends of the two connecting rod segments 21 away from the adjusting sleeve 22. In this way, by respectively screwing the two connecting rod segments 21 into the adjusting sleeve 22 and adjusting the length of the cross bar 2 according to the number of turns of screwing, the relative position of the connecting rod segment 21 relative to the adjusting sleeve 22 is adjusted, thereby adjusting the length of the entire cross bar 2. The threaded adjustment can be continuously and smoothly adjusted within a certain length range according to actual needs, rather than in a jumpy manner, with good versatility. Preferably, in some embodiments, in order to facilitate the operation of rotating the adjusting sleeve 22, an operation handle is provided on the adjusting sleeve 22, and two operation handles are provided and oppositely arranged on the outer side wall of the adjusting sleeve 22.

[0033] Specifically, in some embodiments, the adjusting sleeve 22 is respectively threadedly connected to the two connecting rod segments 21 in opposite directions. In this way, by rotating the adjusting sleeve 22 in the forward and reverse directions around the axis of the adjusting sleeve 22, the two connecting rod segments 21 can be driven to approach or separate from each other, thereby realizing the adjustment of the length of the cross bar 2. By rotating the adjusting sleeve 22, the two cross bars 2 can be driven to move simultaneously, improving the rate of length adjustment and thus the installation efficiency of the edge protection device 100.

[0034] Specifically, in some embodiments, a locking portion 221 for locking the adjusting sleeve 22 and the connecting rod segment 21 is provided on the adjusting sleeve 22. In this way, even when the threads on the adjusting sleeve 22 or the connecting rod segment 21 fail, the relative movement of the adjusting sleeve 22 and the two connecting rod segments 21 can still be restricted, playing a dual limiting role, thereby improving the protection effect. It should be noted that the locking portion 221 is not specifically limited. In this embodiment, the locking portion 221 includes a locking pin or a fastening screw provided on the adjusting sleeve 22.

[0035] Specifically, in some embodiments, a plurality of the cross bars 2 are vertically arranged at intervals between every two adjacent vertical rods 1. By arranging a plurality of cross bars 2 at intervals in the axial direction of the vertical rod 1, the connection stability and anti-deformation ability between every two adjacent vertical rods 1 are further enhanced, which is equivalent to adding an additional protective barrier and improving the safety protection level. In addition, since the lengths of the respective cross bars 2 are adjustable, the lengths of the respective cross bars 2 can be adjusted separately to adapt to vertical rods 1 of different shapes, further improving the versatility.

[0036] Specifically, in some embodiments, a connecting support rod 24 is provided between two adjacent cross bars 2 in the vertical direction. The connecting support rod 24 can improve the connection stability of two adjacent cross bars 2 connected thereto, and connect the two cross bars 2 into a whole to jointly bear the load, improving the anti-deformation ability, and thus improving the protection ability. It can be understood that the connecting support rod 24 can be connected between two adjacent adjusting sleeves 22, or can be connected between two adjacent connecting rod segments 21 of different cross bars 2. When connected between two connecting rod segments 21, it can ensure that the distances adjusted by the two connecting rod segments 21 relative to the respective adjusting sleeves 22 are the same, realizing the same-distance adjustment of each cross bar 2, which is beneficial to the two vertical rods 1 connected to each cross bar 2 being vertical and parallel, and not prone to tilting or collapsing, thereby improving the bearing capacity of the guardrail.

[0037] Specifically, please refer to Figure 4 , in some embodiments, a locking portion 3 is provided on the portion of the plug 23 extending into the insertion hole 131. In this way, after the plug 23 is inserted into the insertion hole 131, the plug 23 can be limited by the locking portion 3 to improve the connection stability between the plug 23 and the plug tray 13. In this embodiment, the locking portion 3 includes a locking block hinged to the free end of the plug 23, and an elastic reset member is provided between the locking block and the plug 23. In this way, when the plug 23 is inserted into the insertion hole 131, the elastic reset member will be compressed to allow the plug 23 and the locking block to pass through the insertion hole 131. After passing through the insertion hole 131, the elastic reset member is no longer pressed and drives the locking block to reset. At this time, the locking block can limit the plug 23 from moving out of the insertion hole 131, thereby improving the connection stability between the cross bar 2 and the vertical rod 1. When disassembly is required, only need to press the locking block again and pull out the plug 23 upward, the operation is simple and the installation is convenient. It should be noted that the elastic reset member is not specifically limited and can be a spring, a torsion spring, a hinge, etc.

[0038] Specifically, in some embodiments, the length of the vertical rod 1 is adjustable. In this way, according to the on-site requirements, the length of the vertical rod 1 can be adjusted to meet the protection requirements of different heights. Please refer to Figure 2 , the vertical rod 1 includes a base 11 and a vertical rod segment 12 movably sleeved on the base 11 in the vertical direction. An adjusting portion 4 for adjusting the installation height of the vertical rod segment 12 relative to the base 11 is provided on the base 11. Since the vertical rod segment 12 is movably sleeved on the base 11, it is beneficial for installation. Then, through the adjusting portion 4, the installation height of the vertical rod segment 12 relative to the base 11 can be adjusted, so that the length of the vertical rod 1 can be adjusted in real time according to the requirements during the installation process, and the versatility is good. Please refer to Figure 4, a screw rod 111 with an axis parallel to the vertical direction is provided on the base 11. The adjusting part 4 includes a body part 41 screwed on the screw rod 111 and a supporting part 42 protruding from the body part 41 for supporting the vertical rod section 12. In this way, since the vertical rod section 12 is carried on the supporting part 42, only by rotating the body part 41 can the vertical rod section 12 be driven to move relative to the base 11 along the axial direction of the screw rod 111, thereby adjusting the length of the upright rod 1. The operation is convenient, and the structure is simple, which is beneficial to quick installation and disassembly.

[0039] Specifically, considering that each upright rod 1 needs to be fixedly installed at a fixed point after determining the installation position, in some embodiments, an installation hole for installing column foot screws is formed on the base 11 or a pin protruding from the bottom of the base 11 is provided, and the pin is inserted into the ground to achieve positioning installation.

[0040] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
