[0037] Example 1

[0038] like Figure 1-Figure 5 As shown, this embodiment provides a protective fence for road construction, including: a support column 1, a telescopic plate assembly 3, two connecting sleeves 4,

[0039] A counterweight block 5 is provided at the bottom of the support column 1 to improve the placement stability of the support column 1. A plurality of connection components 2 are provided on the support column 1. The plurality of connection components 2 are spaced apart along the axial direction of the support column 1. Each connection component 2 includes a plurality of connection heads 201. The plurality of connection heads 201 are spaced apart along the circumference of the support column 1. The connection heads 201 are oriented horizontally.

[0040] The length of the telescopic plate assembly 3 can be adjusted;

[0041] Two connecting sleeves 4 are respectively arranged at two ends of the telescopic plate assembly 3, and the connecting sleeves 4 can be detachably connected to the connecting head 201;

[0042] See also Figure 3 In the figure, two groups of connection components 2 are set on the support column 1 as an example. Each group of connection components 2 has two connecting heads 201. The two support columns 1 are placed in parallel. The two ends of a group of telescopic plate components 3 are respectively connected to a group of connection components 2 on the two support columns 1 through the horizontal connection and cooperation of the connecting sleeve 4 and the connecting head 201. Then, the telescopic plate components 3 are installed on each group of connection components 2 of the two support columns 1 to assemble a group of guardrail units. A single group of guardrail units is in a straight line shape. When a longer straight-line protective fence needs to be assembled, it is only necessary to add a support column 1 and a group of telescopic plate components 3 with one end not connected on the basis of a group of guardrail units. By analogy, the corresponding protective fence is assembled according to the required length;

[0043] When a nonlinear protective fence needs to be assembled, the two connectors 201 in each set of connecting components 2 are arranged at an angle, see Figure 1 On the basis of a set of guardrail units, a support column 1 and a set of telescopic plate components 3 with one end not connected are added, and so on, a nonlinear protective fence can be assembled. At this time, the assembled protective fence can be open or closed, and has a wider range of applications.

[0044] Example 2

[0045] This embodiment provides a protective fence for road construction, which, in addition to the technical solutions of the above embodiments, also discloses a structure of a connecting assembly 2;

[0046] See also Figure 2 Each connecting assembly 2 further includes: an annular groove 202, a plurality of angle adjustment seats 203,

[0047] The annular groove 202 is formed on the outer wall of the support column 1;

[0048] The angle adjustment seat 203 is connected to the annular groove 202 by sliding along the circumference of the support column 1. The number of the angle adjustment seat 203 is the same as the connector 201. In the figure, two angle adjustment seats 203 are taken as an example. The angle adjustment seat 203 can slide in the annular groove 202. The sliding between the angle adjustment seat 203 and the annular groove 202 does not need to be provided with a locking structure. When the positions of the two support columns 1 are fixed, the two support columns 1 are fixed by the telescopic plate assembly 3. The corresponding angle adjustment seats 203 on the two support columns 1 will naturally be fixed relative to the support column 1. Each angle adjustment seat 203 is provided with a connector 201.

[0049] By providing the annular groove 202 and the angle adjustment seat 203, the direction of the connector 201 on the support column 1 can be flexibly adjusted, such as Figure 1The two connectors 201 are vertically distributed. Figure 2 The two connecting heads 201 are parallel to each other and can be distributed at other angles, which improves the flexibility of assembling the protective fence.

[0050] See also Figure 5 In this embodiment, a protective cover 204 is provided on the angle adjustment seat 203, and the connecting head 201 is arranged in the protective cover 204. The connecting cover 4 can be inserted into the protective cover 204 and detachably connected with the connecting head 201; in this way, when the support column 1 is not in use, the connecting head 201 can be hidden in the protective cover 204 to avoid damage to the connecting head 201. After being assembled into a protective fence, the connection point between the connecting head 201 and the connecting column is protected to improve the structural stability of the protective fence.

[0051] Example 3

[0052] This embodiment provides a protective fence for road construction, which, in addition to the technical solutions of the above embodiments, also discloses a structure of a telescopic plate assembly 3;

[0053] See also Figure 5 The outer wall of the connector 201 is provided with an external thread, and the inner wall of the connector sleeve 4 is provided with an internal thread adapted to the connector 201. The connector sleeve 4 is rotatably connected to the end of the telescopic plate assembly 3, and is easy to disassemble and assemble;

[0054] The telescopic plate assembly 3 includes: two connecting plates 301, two mounting seats 303, and a locking member 304.

[0055] See also Figure 4 , two connecting plates 301 are arranged in parallel, and locking grooves 302 are opened on the two connecting plates 301 along the length direction, and the two locking grooves 302 have overlapping parts on the vertical projection plane;

[0056] The two mounting seats 303 are respectively arranged at ends of the two connecting plates 301 which are farther apart from each other, and the connecting sleeve 4 is rotatably connected to the mounting seats 303;

[0057] The locking member 304 can lock or loosen the two connecting plates 301. In this embodiment, the locking member 304 is a screw rod and a nut. The diameter of the fixed end of the screw rod and the nut is larger than the width of the locking groove 302. The length of the locking groove 302 is larger than the diameter of the threaded end of the screw rod. The threaded end of the screw rod passes through the two locking grooves 302 in sequence and is threadedly connected with the nut.

[0058] In this embodiment, after the nut is loosened, a gap appears between the two connecting plates 301. At this time, the two plates can be manually pushed toward each other or pulled away from each other, thereby shortening or lengthening the length of the telescopic plate assembly 3. When the length formed by the two connecting plates 301 reaches the required range, the two connecting plates 301 can be locked by tightening the nut.

[0059] Preferably, in the present embodiment, racks 305 are provided on the side walls of the two connecting plates 301 that are close to each other. The length direction of the racks 305 is the same as the length direction of the connecting plates 301. When the locking member 304 releases the two connecting plates 301, the two racks 305 can approach and move away from each other in the length direction. When they are away from the locking member 304 that locks the two connecting plates 301, the two racks 305 are meshed with each other. This can improve the structural stability of the two connecting plates 301 in the locked state.

[0060] The embodiments of the utility model are described above in conjunction with the accompanying drawings. In the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the enlightenment of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
