Specific embodiments
[0023] In order to make the purpose and advantages of the present utility model more clear, the present utility model will be specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific implementation manners of the present utility model, and does not strictly limit the specific protection scope claimed by the present utility model.
[0024] Such as Figures 1-5As shown in the figure, a road maintenance warning fence includes road piers 101 and railings 102. The railings 102 are inserted into the interior of the road piers 101. The railings 102 are divided into two sections. An extension rod 103 is slidably connected inside the railings 102 and is located between the two sections of railings 102. The interior of the extension rod 103 is a cavity. An installation box 2 is fixedly installed on the outer side of the road pier 101. A limiting mechanism is arranged inside the installation box 2, and an extension mechanism is arranged inside the extension rod 103. The limiting mechanism includes an installation groove 201, a compression spring 202, a square plate 203, a limiting block 204, an installation plate 205, and a matching groove 206. The installation groove 201 is opened on the inner side of the installation box 2. One end of the compression spring 202 is fixedly connected to the inner wall of the installation box 2. The square plate 203 is fixedly connected to the other end of the compression spring 202. The limiting blocks 204 are fixedly connected to the top and bottom of the inner wall of the installation groove 201. The installation plates 205 are respectively fixedly connected to the ends of the railings 102. The installation plates 205 are respectively movably arranged inside the installation box 2. The diameter of the installation plates 205 is smaller than that of the installation groove 201. The matching grooves 206 are respectively opened on both sides of the installation plates 205. The matching grooves 206 cooperate with the limiting blocks 204. When the staff installs the railings 102 inside the road piers 101, they need to first insert the railings 102 and the installation plates 205 into the interior of the road piers 101 and penetrate the road piers 101. At the same time, the matching grooves 206 on both sides of the installation plates 205 are adapted to the limiting blocks 204, and the railings 102 and the installation plates 205 are pushed outward, so that the installation plates 205 penetrate the railings 102 and penetrate the installation groove 201, and the installation plates 205 are inserted into the interior of the installation box 2. At the same time, the square plate 203 will be pushed outward and the compression spring 202 will be compressed. Then, the railings 102 and the installation plates 205 are rotated about ninety degrees. At the same time, under the rebounding force of the compression spring 202, the square plate 203 and the installation plates 205 can be pushed, and with the blocking cooperation of the limiting blocks 204, the installation plates 205 can be limited and installed inside the installation box 2, and at the same time, the railings 102 can be installed and limited inside the road piers 101, avoiding the separation of the railings 102 from the road piers 101 easily under the action of external forces, thereby increasing the firmness of the connection between the railings 102 and the road piers 101.
[0025] As Figure 3 and Figure 4As shown, the extension mechanism includes a round shaft 301, an elastic clamp 302, a limiting groove 303 and a limiting column 304. The round shaft 301 is fixedly connected to the inside of the extension rod 103, the elastic clamp 302 is sleeved on the surface of the round shaft 301, the limiting groove 303 is respectively opened at the top and bottom of the inner wall of the railing 102, one end of the limiting column 304 is fixedly connected to the outside of the elastic clamp 302, and the other end of the limiting column 304 passes through the extension rod 103 and extends to the inside of the limiting groove 303. When the fence is used and the length of the railing 102 needs to be adjusted, the staff can hold the railing 102 and the extension rod and pull the railing 102 and the extension rod to both sides. The railing 102 slides on the surface of the extension rod. When the railing 102 slides on the surface of the extension rod, the limit column 304 can be squeezed inward. After the limit column 304 is subjected to pressure, it will squeeze the elastic clip 302 at the same time, and drive the limit column 304 to disengage from the limit groove 303. Then, after the railing 102 is continuously pulled to adjust to a suitable length, the limit column 304 can be pushed to adapt to the corresponding limit groove 303 under the rebound force of the elastic clip 302. The length of the railing 102 can be flexibly adjusted, and can be adjusted according to different construction requirements or traffic conditions. It can adapt to various scenes and changes, thereby enhancing the flexibility and practicality of the fence.
[0026] like Figure 1 and Figure 2 As shown, a protrusion 401 is fixedly connected to the end of the handrail 102, and a groove 402 is provided on the surface of the extension rod 103 for use with the protrusion 401. When the length of the handrail 102 is adjusted to make the handrail 102 slide on the surface of the extension rod, the protrusion 401 cooperates with the groove 402 to limit the extension rod and the handrail 102 to each other, thereby preventing the handrail 102 from rotating on the surface of the extension rod when the length of the handrail 102 is adjusted, thereby affecting the normal operation of the extension mechanism.
[0027] like Figure 3 and Figure 4 As shown, a telescopic rod 5 is installed on the inner side of the elastic clamp 302, and the two ends of the telescopic rod 5 are respectively fixedly connected to the top and bottom of the inner side of the elastic clamp 302. When the elastic clamp 302 is squeezed and deformed, the telescopic rod 5 can provide better support and fixation, reduce the shaking of the elastic clamp 302 and the limiting column 304, and at the same time, under the action of the telescopic rod 5, the contraction performance of the elastic clamp 302 can be increased, its stability can be enhanced, and the service life of the elastic clamp 302 can be extended.
[0028] like Figure 3 and Figure 4As shown, a limiting ring 6 is sleeved on the surface of the circular shaft 301. The limiting rings 6 are respectively located on the front side and the rear side of the elastic clip 302. After the elastic clip 302 is deformed under pressure, in order to prevent the elastic clip 302 from sliding and displacing on the surface of the circular shaft 301, the limiting ring 6 can assist in limiting the elastic clip 302 to prevent it from driving the limiting post 304 to displace after displacement and making the limiting post 304 unable to cooperate and connect with the limiting groove 303.
[0029] As Figure 3 and Figure 4 shown, circular holes 7 are formed in both the top and the bottom of the surface of the extension rod 103. The diameter of the circular hole 7 is adapted to the limiting post 304. When the limiting post 304 is in cooperation and connection with the limiting groove 303, the limiting post 304 needs to observe the extension rod 103 first. Therefore, the circular hole 7 is provided to facilitate the limiting post 304 to penetrate through the extension rod 103 and enable the limiting post 304 to move flexibly inside the circular hole 7, so as to flexibly adjust the length of the railing 102.
[0030] As Figure 3 and Figure 4 shown, the number of the limiting grooves 303 is several, and they are evenly distributed on the top and the bottom of the inner wall of the railing 102. The end of the limiting post 304 is tapered. The limiting post 304 is used in cooperation with the limiting groove 303. By providing a plurality of limiting grooves 303, the length of the railing 102 can be flexibly adjusted as needed, so that the limiting post 304 is respectively adapted to the limiting grooves 303 at different positions, improving the compatibility and practicability of the extension mechanism.
[0031] The working principle of the utility model is as follows: When the staff needs to install the railing 102 inside the road pier 101, the railing 102 and the mounting plate 205 can be first inserted into the road pier 101 and penetrate through the road pier 101. At the same time, the mating grooves 206 on both sides of the mounting plate 205 are adapted to the limit blocks 204, and the railing 102 and the mounting plate 205 are pushed outward, so that the mounting plate 205 penetrates through the railing 102 and the mounting groove 201, and the mounting plate 205 is inserted into the interior of the mounting box 2. At the same time, the square plate 203 will be pushed outward and the compression spring 202 will be compressed. Then, the railing 102 and the mounting plate 205 are rotated by about ninety degrees. At the same time, under the rebounding force of the compression spring 202, the square plate 203 and the mounting plate 205 can be pushed, and with the blocking cooperation of the limit blocks 204, the mounting plate 205 can be limited and installed inside the mounting box 2, and at the same time, the railing 102 can be installed and limited inside the road pier 101, preventing the railing 102 from being easily separated from the road pier 101 under the action of external forces. When using the fence and it is necessary to adjust the length of the railing 102, the staff can hold the railing 102 and the extension rod and pull the railing 102 and the extension rod to both sides, so that the railing 102 slides on the surface of the extension rod. When the railing 102 slides on the surface of the extension rod, the limit post 304 can be squeezed inward. After the limit post 304 is under pressure, it will also squeeze the elastic clip 302 and drive the limit post 304 to disengage from the limit groove 303. Then, after continuously pulling the railing 102 to adjust to a suitable length, under the rebounding force of the elastic clip 302, the limit post 304 can be pushed to be adapted to its corresponding limit groove 303, and the length of the railing 102 can be flexibly adjusted.
[0032] The above is only the preferred embodiment of the utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the utility model. The structures, devices and operation methods not specifically described and explained in the utility model, unless otherwise specified and limited, are implemented according to the conventional means in the art.
