Figure 5 It is a schematic three-dimensional structure diagram of the guard plate used in a bridge protection device that is easy to install provided by an embodiment of this application.

[0030] The embodiments of this application provide a bridge protection device that is easy to install, such as Figure 1As shown, it includes a bottom plate 100, a plurality of elastic clamping components 200, two guide plates 300 and a guard plate 400. Among them, the bottom plate 100 is a structure for installing and supporting other components. The elastic clamping components 200 can achieve clamping, the guide plates 300 can provide guidance for the guard plate 400, and the guard plate 400 can play a protective role.

[0031] As Figure 3 shown, a plurality of mounting holes 110 are provided on the upper surface of the bottom plate 100. The mounting holes 110 extend in the vertical direction. The plurality of mounting holes 110 are arranged at intervals along the length direction of the bottom plate 100. A receiving hole 120 is provided on the circumferential wall of the mounting hole 110. The receiving hole 120 extends in the width direction of the bottom plate 100 and communicates with the mounting hole 110. That is to say, the receiving hole 120 is opened on the circumferential wall of the mounting hole 110 and is perpendicular to the mounting hole 110.

[0032] As Figure 1 shown, the elastic clamping components 200 are arranged in the receiving holes 120 one by one. When the elastic clamping components 200 are subjected to an external force, they can expand and contract along the axial direction of the receiving holes 120, so as to realize the clamping and loosening of other components. In the natural state (not stressed) of the elastic clamping components 200, at least a part of them can extend into the mounting holes 110.

[0033] As Figure 1 and Figure 3 shown, the two guide plates 300 are symmetrically arranged at both ends of the bottom plate 100. Two convex plates 310 are provided on the opposite sides of the two guide plates 300. A guide slideway is formed between the two convex plates 310, and the guide slideway can provide guidance.

[0034] As Figure 5 shown, a plurality of mounting shafts 410 are provided at the bottom end of the guard plate 400. The plurality of mounting shafts 410 extend along the length direction of the guard plate 400. The number of the mounting shafts 410 is equal to the number of the mounting holes 110, and the positions correspond one by one. The bottom end of the mounting shaft 410 forms a tip. A limiting hole 420 is provided on the mounting shaft 410. The limiting hole 420 extends in the width direction of the guard plate 400, and the direction of the limiting hole 420 is the same as that of the receiving hole 120.

[0035] During implementation, as Figure 2 shown, receiving holes 120 are provided on both sides of the mounting hole 110. Therefore, there are two elastic clamping components 200 on both sides of the mounting hole 110. The two elastic clamping components 200 do not abut against each other, but have a certain gap, which is convenient for the tip to be inserted and for the tip to apply a force to the two elastic clamping components 200.

[0036] As Figure 2As shown, when the mounting shaft 410 is inserted into the mounting hole 110, the tip can abut against the elastic clamping component 200, applying a force to the elastic clamping component 200 to cause the elastic clamping component 200 to retract into the receiving hole 120, so that the mounting shaft 410 can continue to be inserted into the mounting hole 110. As the mounting shaft 410 descends, when the limiting hole 420 is opposite to the receiving hole 120, the elastic clamping component 200 can extend out of the receiving hole 120 and extend into the limiting hole 420 to achieve clamping of the mounting shaft 410.

[0037] During use, place the bottom plate 100 in the area to be protected, insert the guard plate 400 into the guiding chute, the mounting shaft 410 of the guard plate 400 can be inserted into the mounting hole 110, the tip of the mounting shaft 410 can abut against the elastic clamping component 200, causing the elastic clamping component 200 to retract into the receiving hole 120. As the mounting shaft 410 descends, the limiting hole 420 can be opposite to the receiving hole 120. At this time, the elastic clamping component 200 can extend out of the receiving hole 120 and extend into the limiting hole 420 to achieve clamping, realizing the fixation of the mounting shaft 410 and the mounting hole 110, that is, realizing the installation of the guard plate 400.

[0038] Compared with the prior art, when installing this bridge protection device that is easy to install, only need to insert the guard plate 400 along the guiding slideway, insert the mounting shaft 410 into the mounting hole 110, and the elastic clamping component 200 can automatically achieve clamping. The whole process does not require the installation of bolts, is convenient and fast to operate, and there is no risk of loss of bolts and nuts.

[0039] In some embodiments, as Figure 4 shown, the elastic clamping component 200 includes a spring 210 and a clamping shaft 220. One end of the spring 210 is connected inside the receiving hole 120, and the other end of the spring 210 is connected to the clamping shaft 220. When the tip presses the clamping shaft 220 downward, the clamping shaft 220 can compress the spring 210 and thus retract into the receiving hole 120.

[0040] The lower surface of the clamping shaft 220 is provided with a disassembly inclined surface. When it is necessary to disassemble the guard plate 400, the disassembling personnel lift the guard plate 400 upward, causing the mounting shaft 410 to be lifted upward. The limiting hole 420 can abut against the disassembly inclined surface, causing the clamping shaft 220 to gradually retract into the receiving hole 120, releasing the clamping function of the clamping shaft 220 and realizing the disassembly of the guard plate 400.

[0041] In some embodiments, as Figure 1 and Figure 4 shown, both the receiving hole 120 and the limiting hole 420 are square holes, and the clamping shaft 220 is a square shaft. The square shaft will not rotate, which is more convenient for the tip to abut, and it is also more convenient for the orifice of the limiting hole 420 to abut during disassembly, and the structure is reasonable.

[0042] In some embodiments, such as Figure 3 and Figure 4 shown, the receiving hole 120 penetrates through the bottom plate 100, facilitating the installation of the elastic clamping component 200. The elastic clamping component 200 further includes a plug 230. One end of the spring 210 away from the clamping shaft 220 is connected to the plug 230. In this way, during installation, the clamping shaft 220 and the spring 210 can be inserted from the orifice of the receiving hole 120, and then the plug 230 is connected to the orifice of the receiving hole 120 to complete the installation of the entire elastic clamping component 200.

[0043] In some embodiments, the plug 230 is welded to the orifice of the receiving hole 120 to achieve the fixed connection between the plug 230 and the bottom plate 100, and it can withstand the extrusion of the spring 210.

[0044] In other embodiments, the plug 230 is connected to the orifice of the receiving hole 120 by bolts. Some through holes are provided on the plug 230, and some threaded holes are provided near the orifice of the receiving hole 120. Then, the plug 230 is fixedly installed at the orifice of the receiving hole 120 by means of bolt connection, and it can also withstand the extrusion of the spring 210. This structure enables disassembly and assembly, facilitating the maintenance of the elastic clamping component 200.

[0045] In some embodiments, such as Figure 5 shown, a handle 430 is provided on the guard plate 400. The disassembling personnel can install and disassemble through the handle 430, which is convenient for the disassembling personnel to install and disassemble, and the operation is convenient.

[0046] In some embodiments, such as Figure 5 shown, the guard plate 400 is provided with a plurality of weight-reducing holes 440 to appropriately reduce the weight of the entire guard plate 400, facilitating installation and disassembly. In this structure, it can also be understood that the guard plate 400 is welded by a plurality of plate members or rod members, and the structural strength of the guard plate 400 only needs to meet the protection requirements.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, and are not intended to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
