[0022] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0023] like Figures 1-3 As shown in this embodiment, a protective device for road and bridge construction includes a first column 2, a second column 5 on one side of the first column 2, a protective mesh plate 1 installed between the first column 2 and the second column 5, an assembly groove 3 on the side wall of the first column 2 facing away from the protective mesh plate 1, a quick-locking assembly 6 installed in the assembly groove 3, and an assembly block 4 installed on the side wall of the second column 5 facing away from the protective mesh plate 1. Limiting grooves 7 are symmetrically opened on both sides of the assembly block 4. The quick-locking assembly 6 includes a limiting post 601, an installation cavity 602, a connecting rod 603, a linkage rod 604, a spring 605, and a guide groove 600. 06. Linkage plate 607 and guide block 608. There are two mounting cavities 602, which are symmetrically opened on both sides of the column 1 2. Guide groove 606 is reserved in the lower part of the side walls of the mounting cavity 602. Guide block 608 is installed at the guide groove 606. There are two guide blocks 608. Linkage plate 607 is connected between the two guide blocks 608. Linkage rod 604 is installed on one side of the top of guide block 608. Connecting rod 603 is installed on one side wall of linkage rod 604. Limiting post 601 is connected to the bottom of connecting rod 603. Spring 605 is installed at the bottom of guide block 608.

[0024] This utility model provides a road and bridge construction protective device that enables rapid connection between two adjacent protective devices without the aid of external bolts. It solves the problem that existing road and bridge protective devices mainly consist of two columns, a protective plate installed between the two columns, a splicing block installed on one column, and a splicing groove installed on the other column. When installing the protective device at the road and bridge construction site, the splicing blocks and splicing grooves on the two adjacent protective devices are fitted together, and then external bolts are used for locking the connection. This achieves the connection between the two adjacent protective devices during use. Although splicing blocks, splicing grooves, and external bolts can achieve rapid connection between adjacent protective devices... While reliable connection between protective devices is possible, the repeated tightening of bolts during assembly is cumbersome, resulting in low assembly efficiency and hindering efficient installation and use. The present invention addresses this problem by utilizing the weight of one protective device to lower the linkage plate 607 on the other. As the linkage plate 607 moves downward, the limiting post 601 extends from the side wall of the mounting cavity 602 under the action of the linkage rod 604 and connecting rod 603. This allows the limiting post 601 to be inserted into the corresponding limiting groove 7, enabling rapid assembly and connection of the two adjacent protective devices.

[0025] like Figures 1-2 As shown, the protective mesh panel 1 is made of stainless steel. The protective mesh panel 1 is welded to the first post 2 and the protective mesh panel 1 is welded to the second post 5.

[0026] As one implementation method, the protective netting 1 is mainly used to block the construction site of roads and bridges, prevent pedestrians from accidentally entering, and prevent debris from accidentally flying out of the construction site.

[0027] like Figures 1-3 As shown, both column 1 (2) and column 2 (5) have a fixed support foot at their bottom, and the fixed support foot has a pre-drilled mounting hole.

[0028] As one implementation method, the built-in fixed supports can be used to reliably install and fix the first column 2 and the second column 5 at the construction site.

[0029] like Figure 1 , Figure 3 and Figure 4 As shown, the linkage plate 607 slides with the assembly groove 3, and the guide block 608 is formed on the linkage plate 607.

[0030] As one implementation method, the sliding fit installation method makes it more convenient for the linkage plate 607 to slide within the assembly groove 3.

[0031] As shown in the figure Figure 3As shown, the guide block 608, guide groove 606, and lower part of mounting cavity 602 are all in sliding fit.

[0032] In one implementation, the guide block 608 cooperates with the guide groove 606 to ensure that the linkage plate 607 can slide easily up and down along the assembly groove 3.

[0033] like Figure 1 , Figure 3 and Figure 4 As shown, the top end of the spring 605 is welded to the guide block 608, and the bottom end of the spring 605 is welded to the bottom end of the mounting cavity 602.

[0034] In one implementation, when not assembled, the spring 605 is in its normal extended state. At this time, the linkage plate 607 is lifted by the action of the spring 605. When the protective devices are assembled and connected, the linkage plate 607 will be pressed down, thereby compressing the spring 605. When the protective devices are disassembled later, the linkage plate 607 will automatically spring back to its original position after the pressure is removed by the action of the spring 605, thus facilitating the next assembly and use of the protective devices.

[0035] like Figure 3 and Figure 5 As shown, one end of the connecting rod 603 is hinged to the limiting post 601, and the other end of the connecting rod 603 is hinged to the linkage plate 607.

[0036] In one implementation, when the linkage rod 604 moves down, the connecting rod 603 can push the limiting post 601 out of the side wall of the mounting cavity 602 so as to push the limiting post 601 into the corresponding limiting groove 7.

[0037] like Figure 3 and Figure 4 As shown, the limiting post 601 slides with the side wall of the mounting cavity 602, and the limiting post 601 is dimensionally matched with the limiting groove 7.

[0038] As one implementation method, the sliding fit installation method makes it easier for the limiting post 601 to slide relative to the side wall of the mounting cavity 602.

[0039] The specific implementation process of this embodiment is as follows: When assembling two adjacent protective devices at a road and bridge construction site, one protective device is first fixed, and then the assembly block 4 on the other protective device is inserted into the assembly slot 3 on the other protective device. During the insertion of the assembly block 4, pressure is applied to the corresponding linkage plate 607. After being pressed, the linkage plate 607 will drive the connecting rod 603 to rotate. While the connecting rod 603 is rotating, the limiting post 601 will extend from the side wall of the mounting cavity 602 so that after the limiting post 601 is inserted into the corresponding limiting slot 7, the two adjacent protective devices can be quickly assembled and connected. Because the above assembly method eliminates the tedious operation of repeatedly tightening bolts for locking, the assembly efficiency between the two adjacent protective devices is higher, which facilitates the efficient installation and use of the protective devices.

[0040] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
