[0002] Guardrail net is a fixed mesh wall constructed with mesh and columns. It can be widely used in roads, railways, test sites, construction sites and other places to protect personal safety and equipment and facilities. It can be seen everywhere in daily life.

[0003] For example, a highway guardrail net disclosed in the patent with patent number CN213267638U, although the highway guardrail net increases the anti-collision property of the highway guardrail by setting the first connecting plate and the second connecting plate, makes the highway guardrail not easy to be damaged, and improves practicality; however, when the highway guardrail net is actually used, the first bolt and the nut are used to fix the first connecting block and the second connecting block to realize the installation of the protection frame on the second column, so that when the protection frame is disassembled and assembled, the bolts need to be tightened multiple times, and the operation is relatively cumbersome. At the same time, there is a lack of protection for the guardrail between the first column and the second column in the guardrail net, which makes the guardrail easy to be damaged by impact, so it needs to be improved.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention, through the arrangement of the locking cavity, the locking member and the fixing plate, enables the locking member to pass through the fixing plate, extend into the corresponding locking cavity and rotate, so that the fixing plate can be fixed at the upper end of the column, so that the installation frame is fixed between the columns. Compared with the existing fixing method, the present invention adopts the locking member for locking, which is simple and convenient to operate and is easy to use.

[0013] 2.

DETAILED DESCRIPTION

[0023] In order to further understand the content of the present invention, the present invention is described in detail in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are only for explaining the present invention and are not intended to limit it.

[0024] The following combination Figure 1-Figure 7 The present embodiment is further described in detail.

[0025] Combination Figure 1-Figure 7As shown, a guardrail net with an anti-collision function in this embodiment includes columns 100 arranged parallel to each other, and slide grooves 300 are provided on the opposite sides of the columns 100 in the vertical direction. A mounting frame 120 is slidably provided between the slide grooves 300, and a protective net 130 is provided in the mounting frame 120. Fixed plates 140 overlapped on the upper end surfaces of the corresponding columns 100 are provided at both ends of the upper side surfaces of the mounting frame 120; a locking cavity 400 is provided at the upper end of the column 100, and a locking member that penetrates the fixing plate 140 and extends into the locking cavity 400 is provided at the upper end of the column 100. The locking member is rotated to realize the fixation of the fixing plate 140 at the upper end of the column 100, and a fixing member for fixing the rotated locking member is also provided in the locking cavity 400; a protective component for protecting the protective net 130 is provided on the side of the column 100.

[0026] In actual use of this embodiment, a mounting plate 180 is fixed on the lower end surface of the column 100, and the mounting plate 180 is fixed to the ground by bolts 190, so as to realize the fixed installation of the column 100 on the ground; the protective net 130 is connected to the installation frame 120 by welding, and the opposite sides of the installation frame 120 can slide along the corresponding slide grooves 300 through the setting of the slide grooves 300, so as to realize the installation of the installation frame 120 between the opposite columns 100, and then the guardrail net is assembled; Among them, through the arrangement of the locking cavity 400, the locking member and the fixing plate 140, the locking member can pass through the fixing plate 140 and extend into the corresponding locking cavity 400 and rotate, so that the fixing plate 140 can be fixed at the upper end of the column 100, so that the installation frame 120 is fixed between the columns 100 to prevent it from sliding in the slide groove 300. Compared with the existing installation method, the locking member in this embodiment is more convenient for fixing the installation frame 120 and is easy to use; Among them, by setting the fixing member, the fixing member can fix the rotating locking member, so that the installation frame 120 is better fixed, and it is prevented that the locking member rotates by mistake, causing it to release the fixing of the installation frame 120 and affect its use; Among them, through the provision of the protection component, the protection net 130 in the guardrail net is protected, so that the guardrail net has an anti-collision function.

[0027] Combination Figure 3-Figure 5As shown, in this embodiment, a first notch 112 is provided on the fixing plate 140, and a second notch 310 corresponding to the first notch 112 and connected to the locking cavity 400 is provided on the upper end surface of the column 100; the locking member includes a locking rod 160 and a locking block 410 arranged at one end of the locking rod 160, and a pressure ring 111 is provided on the locking rod 160. The locking block 410 passes through the first notch 112 and the second notch 310 and extends into the locking cavity 400 to make the pressure ring 111 fit on the corresponding fixing plate 140, and the locking member is rotated to misalign the locking block 410 with the second notch 310, so as to achieve the fixation of the locking member in the locking cavity 400.

[0028] In actual use of this embodiment, through the above structure, when the locking rod 160 is held and the locking block 410 is driven to pass through the first notch 112 and the second notch 310 and extend into the locking cavity 400, the pressing ring 111 can press the fixing plate 140 downward to make it abut against the upper end surface of the column 100. At this time, by rotating the locking rod 160, the locking block 410 and the second notch 310 are misaligned, thereby achieving the fixed installation of the installation frame 120 on the column 100. Compared with the existing ones, the process of fixing and installing the installation frame 120 on the column 100 by extending the locking member into the locking cavity 400 and rotating is relatively simple, which facilitates the disassembly and assembly operation of the installation frame 120. Among them, the locking block 410 is adapted to the locking cavity 400, so that when the locking block 410 is extended into the locking cavity 400 and rotates to be misaligned with the second notch 310, the upper and lower side surfaces of the locking block 410 can abut against the upper and lower side walls of the locking cavity 400, thereby preventing the locking block 410 from moving up and down in the locking cavity 400, thereby allowing the mounting frame 120 to be better fixed on the column 100; at the same time, the length of the locking block is adapted to the diameter of the locking cavity 400, that is, when the locking block 410 is extended into the locking cavity 400 and rotates, the locking piece will not shake.

[0029] Combination Figure 4-Figure 5 As shown, in this embodiment, a through hole 510 is provided at the bottom of the locking block 410, and the fixing part includes a placement cavity 460 arranged on the bottom wall of the locking cavity 400, a baffle 420 is provided at the opening of the placement cavity 460, and the placement cavity 460 is provided with a baffle ring 440 through a first spring 450, and the baffle ring 440 is provided with a pin 430 that passes through the baffle 420 and extends into the through hole 510.

[0030] In actual use of this embodiment, a step groove is provided on the bottom wall of the locking cavity 400 and at the opening of the placement cavity 460, and the baffle 420 is installed in the step groove by screws, thereby realizing the disassembly and assembly of the baffle 420 at the opening of the placement cavity 460; wherein, in order to facilitate the installation of the locking member in the column 100, a notch 170 communicating with the locking cavity 400 is provided on one side surface of the column 100, and the notch 170 is used to facilitate the operator to install the locking member; The first spring 450, the retaining ring 440 and the pin 430 are arranged so that in the initial state, the first spring 450 pushes the retaining ring 440 to fit the baffle 420 so that the pin 430 passes through the baffle 420 and extends out; In actual use, such as Figure 6 As shown, the lower end of the lock block 410 and the two sides thereof are provided with inclined surfaces 500, and the upper end of the pin 430 is provided with a guiding hemispherical surface 470 matched with the inclined surface 500, so that when the locking member is rotated, the lock block 410 rotates to drive the inclined surface 500 to squeeze the guiding hemispherical surface 470, so that the pin 430 is retracted into the placement cavity 460, and when the lock block 410 rotates to make the through hole 510 and the pin 430 face each other, under the push of the first spring 450, the retaining ring 440 drives the pin 430 to pass through the baffle 420 and extend into the through hole 510, so as to fix the lock block 410, so that it can no longer rotate in the locking cavity 400, thereby preventing the lock member from rotating by mistake, causing it to release the fixation of the installation frame 120; Among them, through the setting of the retaining ring 440 and the baffle plate 420, the retaining ring 440 can abut against the baffle plate 420, thereby better preventing the first spring 450 from pushing the pin 430 out of the placement cavity 460, resulting in the pin 430 being unable to extend into the through hole 510 to lock and fix the locking block 410.

[0031] Combination Figure 4-Figure 7 As shown, in this embodiment, a mounting cavity 600 is provided in the locking block 410, a through hole 510 is connected to the mounting cavity 600, a cavity connected to the mounting cavity 600 is provided in the locking rod 160, a pressing rod 150 is provided in the cavity, the upper end of which extends out of the locking rod 160, the lower end of the pressing rod 150 is extended into the mounting cavity 600, a pressing plate 610 is provided on the extended end of the pressing rod 150, a pressing column 620 is provided on the pressing plate 610 corresponding to the through hole 510, a second spring 630 for pushing the pressing plate 610 to move upward is provided in the mounting cavity 600, and pressing the pressing rod 150 drives the pressing plate 610 to move downward to drive the pressing column 620 to extend into the through hole 510, so that the pin 430 is disengaged from the through hole 510.

[0032] In actual use of this embodiment, by pressing the pressing rod 150 downward, the pressing rod 150 can drive the pressing plate 610 to move downward, and the pressing column 620 corresponds to the through hole 510, so that the pressing column 620 can extend into the through hole 510, pushing the pin 430 to disengage from the through hole 510 and retract into the placement cavity 460, thereby releasing the fixation of the locking block 410, so that the locking block 410 can rotate in the locking cavity 400, thereby releasing the fixation of the fixing plate 140; The upper end of the second spring 630 is connected to the lower side of the pressing plate 610 by welding, and the lower end abuts against the bottom wall of the installation cavity 600. The second spring 630 is arranged so that the second spring 630 can push the pressing plate 610 to move upward, thereby enabling the pressing plate 610 to drive the pressing column 620 to move upward and out of the through hole 510, so that the pin 430 can enter the through hole 510 again to fix and lock the locking block 410. During actual use, the gap between the cavity and the pressing rod 150 is small. At the same time, the opposite side walls of the pressing plate 610 abut against the side walls of the mounting cavity 600, so that the pressing plate 610 cannot shake in the mounting cavity 600, thereby enabling the pressing plate 610 to move up and down smoothly in the mounting cavity 600, ensuring that the pressing column 620 is aligned with the through hole 510 for easy use.

[0033] Combination Figure 2-Figure 3 As shown, in this embodiment, the protection component includes a mounting frame 200 arranged on opposite sides of two columns 100, and the cross-section of the mounting frame 200 is U-shaped. The protection component also includes a protection plate 210, and both ends of the protection plate 210 are inserted into the corresponding mounting frame 200.

[0034] In actual use of this embodiment, the opening position of the mounting frame 200 is connected to the side wall of the same side of the two columns 100 by welding, so that the protective plate 210 can be preferably extended into the mounting frame 200 for clamping installation. In order to make the clamping installation of the protective plate 210 more stable, a blocking plate is provided at the opening position of the mounting frame 200, and the blocking plate is used to block the two ends of the protective plate 210; In actual use, there is a certain gap between the protective plate 210 and the protective net 130, so that when the protective plate 210 is impacted, the protective plate 210 will deform through the gap, thereby providing a certain protective buffer for the protective net 130, so that the protective net 130 is anti-collision, thereby making the guardrail net have a certain anti-collision function; In order to improve the protection effect of the protection net 130 , a plurality of protection components can be arranged on the opposite sides of the two columns 100 .

[0035] Working principle: When the guardrail net needs to be assembled, the two sides of the installation frame 120 are slid into the column 100 along the corresponding slide grooves 300, and the locking block 410 is driven to extend into the locking cavity 400 and rotate by holding the locking rod 160, so that the locking block 410 rotates in the locking cavity 400, and the inclined surface 500 abuts against the guide hemispherical surface 470 to rotate and squeeze, so that the pin 430 moves downward. When the locking block 410 rotates, the through hole 510 is rotated to the top of the placement cavity 460. At this time, the second spring 630 pushes the pin 430 into the through hole 510, The pin 430 can fix the locking block 410, thereby realizing the assembly of the guardrail net; when the fixing plate 140 needs to be unlocked, the pressing rod 150 is pressed downward, so that the pressing rod 150 drives the pressing plate 610 to drive the pressing column 620 to extend into the through hole 510, and the pin 430 is pushed out of the through hole 510, so that the pin 430 cancels the fixation of the locking block 410, so that the locking block 410 can be rotated in the locking cavity 400 and taken out, thereby releasing the fixation of the fixing plate 140, so that the installation frame 120 can be disassembled.

[0036] In conclusion, the above is only a preferred embodiment of the present invention, and all equivalent changes and modifications made according to the scope of the patent application of the present invention should fall within the scope of the patent of the present invention.
