Technical Field

[0001] The utility model relates to the technical field of municipal guardrails, in particular to a municipal building guardrail. Background Art

[0002] Guardrails are mainly used for the protection and protection of personal safety and equipment facilities in residential, highway, commercial areas, public places and other occasions. Guardrails can be seen everywhere in our lives. The price per meter of guardrails will vary depending on the height.

[0003] With respect to the above-mentioned related technologies, the inventor believes that there are the following defects: when using municipal building guardrails, different road sections have different requirements for guardrail heights. The existing municipal building guardrails have a fixed height, which results in the guardrail height of a section of road not meeting the standard after replanning. At this time, since the height of the municipal building guardrails is fixed, it is necessary to purchase new guardrails, which increases the cost of use. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a municipal building guardrail.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions: a municipal building guardrail, comprising two symmetrical bases, the upper surfaces of the two bases are fixedly provided with support rods, a first connecting rod is commonly fixedly provided on the side walls where the two support rods are close to each other, the bottom surface of the first connecting rod is flush with the bottom surface of the support rod, a second connecting rod is commonly installed on the side walls where the two support rods are close to each other, a plurality of mounting rods are commonly distributed in an array on the side walls where the first connecting rod and the second connecting rod are close to each other, and an adjustment component for adjusting the height of the second connecting rod is provided on the support rod.

[0006] By adopting the above technical solution, when the guardrail is in use and the height of the guardrail needs to be adjusted, the staff needs to start the adjustment component, and then the height of the second connecting rod moves up or down under the action of the adjustment component, thereby adjusting the overall height of the guardrail. In this process, when the road is re-planned, the guardrail does not need to be replaced and can continue to be used, thereby reducing the cost of use.

[0007] Furthermore, the upper surfaces of the two support rods are provided with sliding grooves, and the adjustment assembly includes two sliding rods respectively slidably arranged in the two sliding grooves and a threaded rod rotatably arranged on the bottom wall of the sliding groove, the threaded rod is threadedly connected to the sliding rod, and the two ends of the second connecting rod are respectively fixed to the side walls of the two sliding rods close to each other.

[0008] By adopting the above technical solution, when the staff needs to adjust the height of the second connecting rod, the staff needs to rotate the threaded rod, so that the sliding rod slides up or down under the action of the threaded rod, so that the second connecting rod moves up or down with the sliding rod under the action of the sliding rod, thereby adjusting the overall height of the guardrail.

[0009] Further, the inner bottom walls of the two slide grooves are each provided with a through hole, the inner walls of the two through holes are each provided with a first receiving groove, the bottom surface of the first connecting rod is provided with a rotation groove, the inner top wall of the rotation groove is provided with a second receiving groove, the two opposite inner walls of the second receiving groove are each provided with a rotation groove, the two rotation grooves are both connected to the adjacent first receiving grooves, and the lower end of the threaded rod passes through the through hole and extends into the first receiving groove;

[0011] By adopting the above technical scheme, when the staff needs to rotate the threaded rod, the staff needs to rotate the rotating rod, so that the first bevel gear rotates synchronously with the rotating rod under the action of the rotating rod, so that the two second bevel gears meshing with the first bevel gear rotate under the action of the first bevel gear, and then the rotating rod rotates under the action of the two second bevel gears, so that the other two second bevel gears rotate under the action of the rotating rod, and then the third bevel gear rotates under the action of the second bevel gear, so that the threaded rod rotates under the action of the third bevel gear, thereby reducing the difficulty of the staff to rotate the threaded rod, thereby reducing the difficulty of the staff's work.

[0012] Furthermore, the mounting rod includes a plurality of sleeves distributed in an array on the upper surface of the first connecting rod and a plurality of sleeve rods slidably disposed in the plurality of sleeves respectively, and the upper surfaces of the plurality of sleeve rods are fixed to the bottom surface of the second connecting rod.

[0013] By adopting the above technical solution, when the second connecting rod moves upward or downward under the action of the sliding rod, the sleeve rod slides upward or downward following the second connecting rod under the action of the second connecting rod, thereby causing the sleeve and the sleeve rod to slide relative to each other, thereby reducing the difficulty of sliding the second connecting rod.

[0014] Furthermore, a limiting rod is fixedly provided on the inner bottom wall of the first accommodating groove, a limiting groove is provided on the bottom surface of the third bevel gear, and the limiting rod is rotatably connected to the limiting groove.

[0015] By adopting the above technical solution, when the third bevel gear rotates, the limit rod and the third bevel gear rotate relatively. During this process, the limit rod supports the third bevel gear, thereby reducing the probability of the third bevel gear falling downward under the action of gravity, thereby improving the stability of the device.

[0016] Furthermore, an annular groove is provided on the inner wall of the rotating groove, an annular block is rotatably arranged in the annular groove, and the annular block is fixed to the rotating rod.

[0017] By adopting the above technical solution, when the staff rotates the rotating rod, the annular block rotates synchronously with the rotating rod under the action of the rotating rod. During this process, the side wall of the annular block abuts against the inner wall of the annular groove, thereby reducing the probability of movement during the rotation of the rotating rod, thereby reducing the probability of the first bevel gear and the second bevel gear separating from each other, thereby improving the stability of the device.

[0018] Furthermore, a knob is fixedly disposed on the bottom surface of the rotating rod.

[0019] By adopting the above technical solution, the knob reduces the difficulty for the staff to rotate the rotating rod, thereby reducing the work difficulty of the staff.

[0020] In summary, the utility model has the following beneficial effects:

[0021] 1.
