Description

Technical Field

[0001] This utility model relates to the field of highway operation equipment technology, and in particular to a new type of highway operation indicator equipment. Background Technology

[0002] The safety and smooth flow of highways not only depend on reasonable traffic management and strict laws and regulations, but also require a series of necessary equipment to support them. In order to ensure the efficient operation of highways, the operating and management units should be equipped with a series of key equipment. When carrying out maintenance work on highways, the work site must be equipped with indicator equipment, including warning signs, speed limit signs and directional signs, etc. Vehicles passing through the work site must run according to the indicator equipment and must not interfere with the work.

[0003] Currently, highway signage is inconvenient to move during use. Because the signage used by maintenance workers is generally lightweight, stones or slabs are usually placed on the bottom of the signage to prevent it from being blown over by strong winds. When the signage needs to be moved, the stones or slabs need to be lifted again, which is a complicated process and increases the labor intensity of workers. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a novel highway operation indication device, which solves the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel highway operation indicator device, comprising:

[0006] A counterweight base, with a pair of first square tubes connected to the top of the counterweight base, a second square tube slidably connected inside the first square tubes, an indicator sign fixedly connected to the outside of the second square tubes, and a positioning mechanism provided on the outside of the first square tubes.

[0007] A pair of bearing seats are connected to the bottom left and right positions of the counterweight base, and a shaft is rotatably connected inside the pair of bearing seats. Rollers are connected to both ends of the shaft.

[0008] A handle is attached to the upper right side of the counterweight base.

[0009] As a further technical solution of this utility model, the front and rear sides of the first square tube are connected to support plates, and the bottom of the support plates is fixedly connected to the counterweight base.

[0010] As a further technical solution of this utility model, the positioning mechanism includes a U-shaped plate, both sides of which are fixedly connected to a first square tube. A through hole is opened inside the U-shaped plate, and a positioning rod is connected through the through hole. One end of the positioning rod is connected to a pull plate. A ring is fixedly connected to the outside of the positioning rod and inside the U-shaped plate. A return spring is sleeved on the outside of the positioning rod and at the middle position between the ring and the U-shaped plate. One end of the return spring is fixedly connected to the ring, and the other end of the return spring is fixedly connected to the inner wall of the U-shaped plate.

[0011] As a further technical solution of this utility model, a second positioning hole is provided on the outer side of the first square tube near the U-shaped plate. The position of the second positioning hole corresponds to the position of the through hole, and one end of the positioning rod passes through the interior of the second positioning hole.

[0012] As a further technical solution of this utility model, six first positioning holes are sequentially opened from top to bottom on the outer side of the second square tube near the second positioning hole, and one end of the positioning rod passes through the interior of the first positioning hole.

[0013] As a further technical solution of this utility model, a reflective sticker is connected to the outer side of the counterweight base.

[0014] This utility model provides a novel highway operation indication device, which has the following advantages compared with the prior art:

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This utility model provides a new type of highway operation indicator equipment technical solution: including: a counterweight base 4, a pair of first square tubes 8 connected above the counterweight base 4, a second square tube 10 slidably connected inside the first square tubes 8, an indicator sign 1 fixedly connected to the outside of the second square tubes 10, and a positioning mechanism provided on the outside of the first square tubes 8.

[0025] A pair of bearing seats 11 are connected to the bottom left and right positions of the counterweight base 4. A shaft 12 is rotatably connected inside the pair of bearing seats 11. Rollers 6 are connected to both ends of the shaft 12. A handle 2 is connected to the upper right side of the counterweight base 4. The staff can hold the handle 2 to push the counterweight base 4 to move, thereby improving the flexibility of the sign 1.

[0026] like Figure 1 and Figure 2As shown, support plates 3 are connected to both the front and rear sides of the first square tube 8. The bottom of the support plate 3 is fixedly connected to the counterweight base 4, which helps to further increase the stability of the sign 1 and prevent it from being blown over by strong winds.

[0027] like Figure 3 and Figure 4 As shown, the positioning mechanism includes a U-shaped plate 7, with both sides of the U-shaped plate 7 fixedly connected to the first square tube 8. A through hole 17 is provided inside the U-shaped plate 7, through which a positioning rod 15 is connected. One end of the positioning rod 15 is connected to a pull plate 9. A ring 16 is fixedly connected to the outside of the positioning rod 15 and inside the U-shaped plate 7. A return spring 18 is sleeved on the outside of the positioning rod 15 and at the middle position between the ring 16 and the U-shaped plate 7. One end of the return spring 18 is fixedly connected to the ring 16, and the other end is fixedly connected to the inner wall of the U-shaped plate 7. When the height of the indicator 1 needs to be adjusted, the pull plates 9 on both sides are pulled simultaneously, removing the positioning rod 15 on one side of the pull plate 9 from the inside of the second positioning hole 14 and the first positioning hole 13. This allows for easy adjustment of the height of the second square tube 10 within the first square tube 8. After adjustment, the pull plate 9 is released, and the elasticity of the return spring 18 drives the positioning rod 15 to reset, thus fixing the height of the second square tube 10 within the first square tube 8.

[0028] like Figure 3 and Figure 4 As shown, a second positioning hole 14 is provided on the outer side of the first square tube 8 near the U-shaped plate 7. The position of the second positioning hole 14 corresponds to the position of the through hole 17, and one end of the positioning rod 15 passes through the interior of the second positioning hole 14.

[0029] like Figure 3 and Figure 4 As shown, six first positioning holes 13 are sequentially opened from top to bottom on the outer side of the second square tube 10 near the second positioning hole 14. One end of the positioning rod 15 passes through the interior of the first positioning hole 13. After adjusting the height of the second square tube 10 in the first square tube 8 and aligning the position of the first positioning hole 13 with the position of the second positioning hole 14, the pull plate 9 is released. The elasticity of the return spring 18 is used to drive the positioning rod 15 to reset, thereby fixing the height of the second square tube 10 in the first square tube 8.

[0030] like Figure 1 As shown, reflective stickers 5 are attached to the outer side of the counterweight base 4, which helps to provide a warning effect at night.

[0031] The working principle of this utility model is as follows: By setting a counterweight base 4, the stability of the sign 1 is increased. By setting support plates 3 on the front and rear sides of the first square tube 8, the stability of the sign 1 is further increased, preventing it from being blown over by strong winds. By setting two pairs of bearing seats 11 at the bottom of the counterweight base 4, and setting a rotatably connected shaft 12 and roller 6 inside the bearing seats 11, the operator can hold the handle 2 to push the counterweight base 4 to move, thereby improving the flexibility of the sign 1. When it is necessary to adjust the height of the sign 1, the pull plates 9 on both sides are pulled at the same time, and the positioning rod 15 on one side of the pull plate 9 is taken out from the inside of the second positioning hole 14 and the first positioning hole 13, so that the height of the second square tube 10 in the first square tube 8 can be easily adjusted. After adjustment, the pull plate 9 is released, and the elasticity of the return spring 18 is used to drive the positioning rod 15 to return to its original position, thereby fixing the height of the second square tube 10 in the first square tube 8.

[0032] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
