Description

TECHNICAL FIELD

[0001] The present application relates to the field of road construction, in particular to a protective fence for road construction. BACKGROUND

[0002] The protective fence for road construction is an indispensable safety facility in modern urban construction, widely used in various engineering construction sites to isolate the construction site from the external environment and ensure the safety of pedestrians and vehicles. With the acceleration of urbanization, the frequency of road construction has increased significantly, and the demand for protective fences has also increased.

[0003] However, during transportation or storage, several protective fences often need to be stacked. However, the protective fence in the related art usually includes a base for supporting the body of the protective fence, and the length direction of the base is perpendicular to the length direction of the protective fence. During the stacking of several protective fences, the bases between adjacent two protective fences may interfere with each other, so that after the stacking of the two adjacent protective fences, there is a large gap between the two protective fences, which occupies more storage space. CONTENT OF THE UTILITY MODEL

[0004] In order to save storage space for transportation or storage of the protective fence, the present application provides a protective fence for road construction.

[0005] The protective fence for road construction provided by the present application adopts the following technical solution:

[0006] A protective fence for road construction, comprising a pair of support rods, a telescopic assembly is installed between the pair of support rods, the bottom end of each support rod is connected with a mounting rod which is perpendicular to the support rod, an adjusting member is connected to each support rod, the adjusting member comprises two hinged hinge plates, one of the hinge plates is fixedly connected to the side of the corresponding mounting rod close to the corresponding support rod, and the other hinge plate is fixedly connected to the side of the corresponding support rod, when each mounting rod contacts the side of the corresponding support rod away from the other support rod, the two hinge plates on the same adjusting member are perpendicular to each other.

[0007] By adopting the above technical solution, the protective fence for road construction can realize flexible adjustment and stable fixation between the support rod and the mounting rod. Adjusting the length of the telescopic assembly and pulling the two support rods away from each other can facilitate the adjustment of the length of the protective fence. The two hinge plate structures in the adjusting member allow the mounting rod to be adjusted within a certain range of angle with respect to the support rod. When the mounting rod contacts the side of the corresponding support rod away from the other support rod, the length direction of the mounting rod is perpendicular to the connecting line between the two support rods, which facilitates the stable support of the protective fence on the mounting rod placed on the ground.

[0008] When the protective fence needs to be stored, the telescopic assembly is adjusted to be shortened, and the two support rods are moved towards each other until the telescopic assembly is shortened to the limit position. Then, the mounting rod is rotated relative to the support rods until the two hinge plates contact each other, at which time the length direction of the mounting rod is consistent with the direction of the line between the two support rods. This facilitates the mutual stacking of a plurality of protective fences for storage, thereby saving storage space for transporting or storing the protective fence.

[0009] Preferably, the mounting rod is connected with a locking assembly, the locking assembly includes a threaded rod threadedly connected with the mounting rod, and threaded holes one are formed in the side surfaces of the two support rods away from each other, one end of the threaded rod is threadedly connected with the threaded hole one, and the other end of the threaded rod is fixedly connected with a cap.

[0010] By adopting the above technical scheme, the relative position between the mounting rod and the support rod can be effectively fixed. Specifically, the threaded connection of the threaded rod and the mounting rod allows the threaded rod to be flexibly adjusted in length, so as to be threadedly connected with or separated from the threaded hole one. At the same time, the design of the cap facilitates the operator to exert force to rotate the threaded rod, further improving the convenience of installation and adjustment.

[0011] Preferably, a long hole is formed in the side surface of the mounting rod away from the support rod, the long hole is arranged along the length direction of the mounting rod, a sliding block is slidingly connected in the long hole, the threaded rod penetrates through the sliding block and is threadedly connected with the sliding block, and threaded holes two are formed in the side surfaces of the hinge plates fixedly connected with each support rod, the threaded holes two are used to be threadedly connected with the threaded rod.

[0012] By adopting the above technical scheme, the sliding connection of the sliding block in the long hole can adjust the position of the threaded rod relative to the mounting rod. When the mounting rod contacts the side surface of the corresponding support rod away from the other support rod, the threaded rod can be threadedly connected with the threaded hole one, so as to lock the mounting rod at this time. When the mounting rod contacts the side surface of the corresponding support rod where the threaded hole two is formed, the threaded rod is rotated and threadedly connected with the threaded hole two, so as to lock the mounting rod at this time.

[0013] Preferably, the side wall of the cap is fixedly connected with a rubber layer.

[0014] By adopting the above technical scheme, the fixed connection of the rubber layer with the side wall of the cap can increase the friction force between the user's hand and the cap, which is more labor-saving and convenient when the threaded rod is screwed.

[0015] Preferably, the telescopic assembly comprises a plurality of pairs of connecting members, each of which comprises a connecting one rod and a connecting two rod hingedly connected in the middle, each of the connecting one rods is hingedly connected with one end of the connecting two rod in the adjacent connecting member, one of the connecting one rods at one end of the connecting member is hingedly connected with the adjacent support rod, one of the connecting rods at the other end of the connecting member is hingedly connected with the adjacent support rod, one of the connecting two rods at one end of the connecting member is rotatably connected with a guide block, and one of the connecting one rods at the other end of the connecting member is also rotatably connected with a guide block, a vertical guide groove is formed in one side surface of each of the support rods, and each of the guide blocks is slidably connected with the corresponding guide groove.

[0016] By adopting the above technical scheme, the hinged design of the connecting one rod and the connecting two rod can realize flexible linkage between the plurality of pairs of connecting members, so that the telescopic assembly can be stably and continuously length-adjusted between the two support rods. At the same time, the cooperation of the guide block and the guide groove further improves the stability during the telescoping process, ensuring that the protective fence has good reliability and operational convenience during use.

[0017] Preferably, each of the guide grooves is a dovetail groove, and each of the guide blocks is a dovetail block matched with the guide groove.

[0018] By adopting the above technical scheme, when the guide groove is designed as a dovetail groove and the guide block is designed as a dovetail block matched therewith, the situation that the guide block is detached from the guide groove can be effectively reduced, thereby improving the stability of the telescopic assembly during use.

[0019] Preferably, the support rod is connected with a control assembly for locking the two support rods, the control assembly comprises a locking rope fixedly connected with one of the support rods, and a locking ring fixedly connected with the other support rod, one end of the locking rope is fixedly connected with a hook, and the hook is hung with the locking ring when the telescopic assembly is shortened to the limit state.

[0020] By adopting the above technical scheme, stable locking between the two support rods is realized. Specifically, when the telescopic assembly is shortened to the limit state, the hook is hung with the locking ring, thereby reducing the situation that the telescopic assembly is accidentally stretched, and ensuring that the protective fence maintains a compact form during storage or transportation.

[0021] Preferably, the locking rope is an elastic rope, and the elastic rope is in a stretched state when the hook is hung with the locking ring.

[0022] By adopting the technical scheme, when the hook is hung with the locking ring, the elastic rope is in a stretched state, so that pre-tightening force can be provided for the connection between the two support rods, and the overall stability of the protective fence is enhanced. Meanwhile, by using the elastic force characteristics of the elastic rope, when subjected to external impact or vibration, a certain buffering effect can be achieved, and the impact resistance and service life of the structure are improved.

[0024] 1. Facilitate the mutual stacking of several protective fences for storage, transportation or storage of protective fences, which is more space-saving;

[0025] 2. The entire protective fence has good reliability and operational convenience during use;

[0026] 3. Ensure that the protective fence maintains a compact form during storage or transportation. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0031] The following will be combined with the Figures 1-3 The present application will be further described in detail.

[0032] The embodiment of the present application discloses a protective fence for road construction. Referring to Figure 1 and Figure 2 , the protective fence for road construction includes a pair of support rods 1, a telescopic assembly 2, two mounting rods 3 and two adjusting members 4. Among them, the telescopic assembly 2 is connected between the pair of support rods 1, used to adjust the distance between the two; one support rod 1 corresponds to one mounting rod 3, and the bottom end of the support rod 1 is connected with the corresponding mounting rod 3.

[0033] A pair of support rods 1 are located between two mounting rods 3, and each mounting rod 3 is connected with a corresponding support rod 1 through an adjusting piece 4. The adjusting piece 4 comprises two mutually hinged hinge plates 41, one of which is fixedly connected with one side of the corresponding support rod 1 through a screw, and the other is fixedly connected with one side wall of the corresponding mounting plate.

[0034] When the length direction of the mounting rod 3 is perpendicular to the horizontal line between the two support rods 1, the two hinge plates 41 in the adjusting piece 4 are arranged perpendicular to each other. When the mounting rod 3 is rotated relative to the support rod 1 until the two hinge plates 41 in the same adjusting piece 4 contact each other, the mounting rod 3 is in a folded state, which is convenient for storing the protective fence.

[0035] The telescopic assembly 2 comprises a plurality of pairs of connecting pieces 21, each pair of connecting pieces 21 being composed of a connecting one rod 211 and a connecting two rod 212 which are hinged at the middle. One end of the connecting one rod 211 in each connecting piece 21 is hinged with one end of the adjacent connecting two rod 212. The connecting one rod 211 in one of the connecting pieces 21 located at both ends of the telescopic assembly 2 is hinged with the adjacent support rod 1 at one end, and the connecting two rod 212 is hinged with a guide block 213 at one end; the connecting two rod 212 in the other connecting piece 21 is hinged with the adjacent support rod 1 at one end, and the connecting one rod 211 is hinged with a guide block 213 at one end.

[0036] Referring to Figure 1 and Figure 3 , one side of each support rod 1 is provided with a guide groove 11, one guide block 213 corresponds to one guide groove 11, and the guide block 213 is slidably connected with the guide groove 11. Each guide groove 11 is arranged along the length direction of the support rod 1, and the guide groove 11 is a dovetail groove, and the guide block 213 is a dovetail block matching the shape and size of the dovetail groove.

[0037] In addition, in order to ensure the stability of the mounting rod 3 after being rotated relative to the support rod 1, a locking assembly 5 for locking the mounting rod 3 and the support rod 1 is connected to each mounting rod 3. A long strip hole 31 is formed on the side of the mounting rod 3 away from the support rod 1, and the long strip hole 31 is arranged along the length direction of the mounting rod 3. A sliding block 6 is slidably connected in the long strip hole 31.

[0038] Referring to Figure 2 and Figure 3 , the locking assembly 5 comprises a threaded rod 51 and a cap 52 fixedly connected with one end of the threaded rod 51, and a threaded hole one 12 is formed on the side of each support rod 1 away from the other support rod 1, and a threaded hole two 13 is formed on the side of each hinge plate 41 fixedly connected with the support rod 1. Both the threaded hole one 12 and the threaded hole two 13 are used for threaded connection with the threaded rod 51. The side wall of the cap 52 is fixedly connected with a layer of rubber.

[0039] When the mounting rod 3 contacts the side of the corresponding support rod 1 away from the other support rod 1, the threaded rod 51 is screwed with the threaded hole one 12, at this time, the mounting rod 3 and the support rod 1 are locked. The threaded rod 51 is unscrewed from the threaded hole one 12, then the mounting rod 3 is rotated relative to the support rod 1 until the hinge plate 41 on the mounting rod 3 abuts against the hinge plate 41 on the support rod 1, then the threaded rod 51 is screwed with the threaded hole two 13, at this time, the mounting rod 3 and the support rod 1 are also locked.

[0041] When the telescopic assembly 2 is contracted to the shortest limit, the hook 72 can be just buckled on the locking ring 73 by pulling, at this time, the elastic rope itself tension plays a pulling role.

[0042] The implementation principle of the protective fence for road construction is as follows: when the protective fence needs to be stored, the two support rods 1 are pushed towards each other, at this time, the telescopic assembly 2 gradually presents a folded state. When the telescopic assembly 2 is shortened to the limit position, the hook 72 is hung with the locking ring 73 by pulling. Then the corresponding mounting rod 3 is rotated relative to each support rod 1 until the two hinge plates 41 in each adjusting piece 4 abut against each other, then the threaded rod 51 is screwed with the threaded hole two 13.

[0043] The above are the preferred embodiments of the present application, which do not limit the protection scope of the present application, therefore: all equivalent changes made on the structure, shape and principle of the present application should be covered within the protection scope of the present application.
