[0031] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. It should be noted that the drawings are schematic and not to scale. For the sake of clarity and convenience, the relative sizes and proportions of the parts shown in the drawings are exaggerated or reduced in size, and any sizes are only illustrative and not restrictive.

[0032] Example 1:

[0033] See also Figure 1 - Figure 8As shown, a stable highway contour column and its installation structure include a base 1, a fixing plate 11 is fixedly connected to the top of the base 1, and a number of bolts 12 are symmetrically threaded on the fixing plate 11. A slot is opened on the base 1, and a contour column 2 is inserted into the slot. A sleeve 3 is provided on the outside of the contour column 2, and a reflective film 31 is attached to the outside of the sleeve 3. A mounting assembly 4 is provided in the contour column 2. The base 1 is the basic part of the entire device, used to support and fix the contour column 2. It has certain strength and stability, can withstand the weight of the contour column 2 and its upper structure, and transfer it to the ground. The function of the fixing plate 11 is to be fixedly connected to the ground through bolts 12, and the base 1 is firmly installed on the ground, thereby ensuring the stability of the entire contour column 2 installation structure. It provides a reliable fixing point for the base 1 to prevent the base 1 from moving or tilting during use. The bolts 12 It is used to fix the fixing plate 11 on the ground. By tightening the bolts 12, the fixing plate 11 can be firmly fixed in the installation position, thereby ensuring the stability of the base 1. The tightening degree of the bolts 12 directly affects the stability of the entire device. Therefore, it is necessary to ensure that the bolts 12 are tightened in place during the installation process. The contour column 2 is the core component of the entire device and is used to serve as a warning on the road. The role of the sleeve 3 is to protect the contour column 2 and provide a stable support platform for the reflective film 31. The reflective film 31 can reflect light at night or in dim light conditions to improve road visibility and serve as a warning. The setting of the reflective film 31 is to ensure that the contour column 2 can be clearly seen by the driver under various weather and light conditions, thereby improving road safety. The mounting assembly 4 is an important component inside the contour column 2 and is used to achieve the installation and fixation of the contour column 2;

[0034] The mounting assembly 4 includes a receiving plate 41 fixedly connected to the inner wall of the contour column 2, a first spring 42 fixedly connected to the receiving plate 41, a spiral rod 43 fixedly connected to the end of the first spring 42, a driving rod 44 fixedly connected to the end of the spiral rod 43, a sliding groove 45 is provided on the contour column 2, and a clamping member 46 is provided in the contour column 2. The receiving plate 41 is used to support and fix the first spring 42. The function of the receiving plate 41 is to provide a stable support point for the first spring 42 to ensure that the first spring 42 can work normally inside the contour column 2. The first spring 42 The function of the first spring 42 is to provide elastic force during the installation of the contour column 2. When the driving rod 44 is pressed down, the first spring 42 is tightened and elastic potential energy is stored. When the driving rod 44 is released, the first spring 42 releases the elastic potential energy and pushes the spiral rod 43 to move upward, thereby realizing the installation and fixation of the contour column 2. The function of the spiral rod 43 is to convert the downward force of the driving rod 44 into the rotation of the rotating plate 462, thereby driving the L-shaped block 465 to move. The spiral rod 43 realizes the transmission and conversion of force by cooperating with the spiral groove 463, so that the L-shaped block 465 can be fixed. 65 can be accurately engaged or separated with the card slot 131 on the collar 13. The function of the driving rod 44 is to drive the screw rod 43 to be pressed down by the downward operation, thereby driving the entire installation assembly 4 to work. When the contour column 2 needs to be installed, the driving rod 44 is pressed down, the screw rod 43 is pressed down, the first spring 42 is tightened, and the screw rod 43 drives the rotating plate 462 to rotate through the spiral groove 463, thereby driving the L-shaped block 465 to move, canceling the card slot 131 on the collar 13. After loosening the driving rod 44, the first spring 42 releases its elastic potential energy, pushing the screw rod 43 moves upward, so that the L-shaped block 465 is re-engaged in the slot 131, thereby fixing the contour column 2. The slide groove 45 is used to slide and connect the drive rod 44. The function of the slide groove 45 is to provide a stable sliding channel for the drive rod 44 to ensure that the drive rod 44 can move up and down smoothly on the contour column 2. The setting of the slide groove 45 enables the drive rod 44 to accurately transfer the downward force to the spiral rod 43, thereby realizing the normal operation of the installation component 4. The clamping member 46 cooperates with the slot 131 on the ring 13 to fix and position the contour column 2.

[0035] Specifically, a ring 13 is fixedly connected to the top of the fixed plate 11, and a plurality of slots 131 are evenly distributed on the circumference are provided on the ring 13. The ring 13 is fixedly connected to the top of the fixed plate 11, and a plurality of slots 131 are evenly distributed on the circumference are provided on the ring 13. The function of the ring 13 is to cooperate with the clamping member 46 to achieve the fixation and positioning of the contour column 2. The slot 131 is used to clamp with the L-shaped clamping block 465 in the clamping member 46, so as to firmly fix the contour column 2 on the base 1 to prevent the contour column 2 from loosening or falling off during use.

[0036] Furthermore, the clamping member 46 includes a connecting plate 461 fixedly connected to the inner wall of the contour column 2, a rotating plate 462 is rotatably connected to the connecting plate 461, a spiral groove 463 is provided on the rotating plate 462, an arc groove 464 is provided on the rotating plate 462, an L-shaped clamping block 465 is slidably connected in the arc groove 464, the connecting plate 461 is used to support and fix the rotating plate 462, the function of the connecting plate 461 is to provide a stable support point for the rotating plate 462, to ensure that the rotating plate 462 can work normally inside the contour column 2, and the function of the rotating plate 462 is to cooperate with the screw rod 43 through the spiral groove 463 to move the lower end of the screw rod 43 The pressure is converted into its own rotation. The rotation of the rotating plate 462 drives the L-shaped block 465 to accurately engage or disengage with the groove 131 on the ring 13 through the arc groove 464, thereby fixing and positioning the contour column 2. The spiral groove 463 is used to spirally connect the spiral rod 43. Through the shape and angle of the spiral groove 463, the downward force is converted into the rotation of the rotating plate 462, driving the L-shaped block 465 to move. The arc groove 464 is used to slide the L-shaped block 465 and to apply extrusion force to the L-shaped block 465. The L-shaped block 465 cooperates with the groove 131 on the ring 13 to fix and position the contour column 2.

[0037] Furthermore, the drive rod 44 is slidably connected in the slide groove 45, the spiral rod 43 is spirally connected in the spiral groove 463, the L-shaped block 465 is slidably connected to the contour column 2, and the end of the L-shaped block 465 is clamped in the slot 131. There are multiple arc grooves 464 and L-shaped blocks 465 and they are evenly distributed around the circumference.

[0038] As can be seen from the above, first, place the base 1 into the pre-excavated groove to ensure that the base 1 is horizontal, and then fix the fixing plate 11 to the ground with the bolts 12. The bolts 12 need to be tightened to ensure stability. Next, insert the contour column 2 into the slot of the base 1 to ensure that the contour column 2 is vertical. Pour concrete around the base 1 to further ensure the stability of the contour column 2. When the contour column 2 needs to be fixed to the base 1, press down the drive rod 44. The drive rod 44 drives the spiral rod 43 to press down, the first spring 42 is tightened, and the spiral rod 43 drives the rotating plate 462 to rotate through the spiral groove 463. The arc groove 464 on the rotating plate 462 drives the L-shaped block 465 to move, canceling the groove 13 on the collar 13. 1, at this time, the contour column 2 can be inserted into the slot of the base 1, and the driving rod 44 is released. The first spring 42 releases the elastic potential energy, pushing the spiral rod 43 to move upward, and the spiral rod 43 drives the rotating plate 462 to rotate in the opposite direction through the spiral groove 463. The arc groove 464 on the rotating plate 462 drives the L-shaped block 465 to be re-engaged in the groove 131 on the ring 13, thereby firmly fixing the contour column 2 on the base 1. By setting the installation component 4, the contour column 2 can be effectively prevented from loosening or falling off during use, thereby improving the stability of the entire device. Moreover, the installation of the contour column 2 can be completed by simply pressing down or releasing the driving rod 44, which saves time and effort and improves work efficiency.

[0039] Example 2:

[0040] See also Figure 5 - Figure 6 As shown, this embodiment is basically the same as the previous embodiment, with the difference that an adjustment component 5 is provided on the sleeve 3, and the adjustment component 5 includes a lower pressure ring 51 sleeved on the outside of the sleeve 3, and a bevel block 52 is fixedly connected to the bottom of the lower pressure ring 51. The adjustment component 5 is used to adjust the position of the sleeve 3 on the contour column 2 so as to meet the position height standard of the reflective film 31. The lower pressure ring 51 cancels the squeezing of the bevel block 52 on the lever 54 by the downward pressure operation, so that the lever 54 can be freely opened. The setting of the lower pressure ring 51 makes the operation of the adjustment component 5 more convenient and quick. The position of the sleeve 3 can be adjusted by a simple downward pressure action. The bevel block 52 is used to cooperate with the lever 54. The shape and angle of the bevel block 52 match the shape of the lever 54, so that the lever 54 can open or close under the squeezing of the bevel block 52, thereby adjusting the position of the sleeve 3.

[0041] Specifically, the adjustment assembly 5 also includes a base 53 fixedly connected to the outside of the sleeve 3, and a lever 54 is rotatably connected to the base 53. A rubber block 55 is fixedly connected to the end of the lever 54. The base 53 is used to provide a stable support point for the lever 54 to ensure that the lever 54 can work normally on the sleeve 3. It also serves to connect the sleeve 3 and the lever 54, transmitting the force of the lever 54 to the sleeve 3, thereby adjusting the position of the sleeve 3. The lever 54 is opened or closed by the downward pressure operation of the lower pressure ring 51. The opening or closing of the lever 54 is achieved by the contact or separation of the rubber block 55 and the contour column 2, so that the sleeve 3 can move smoothly on the contour column 2, thereby meeting the position height standard of the reflective film 31. The material of the rubber block 55 has a certain elasticity and friction, and can fit tightly with the contour column 2 under the pressure of the lever 54, ensuring the stable position of the sleeve 3 on the contour column 2 and preventing the sleeve 3 from sliding or loosening during movement.

[0042] Furthermore, the rubber block 55 is fitted on the outside of the contour column 2 , and multiple bases 53 , levers 54 and rubber blocks 55 are provided and evenly distributed around the circumference. The bottom of the inclined block 52 is fitted with the tops of the multiple bases 53 .

[0043] As can be seen from the above, when the position height of the reflective film 31 needs to be adjusted, the lower pressure ring 51 is pushed, and the lower pressure ring 51 drives the inclined block 52 to move upward. The inclined block 52 cancels the squeezing of the lever 54, and the multiple levers 54 can be opened. At this time, the position of the movable sleeve 3 on the contour column 2 is adjusted to meet the position height standard of the reflective film 31. The lower pressure ring 51 is released, and the inclined block 52 squeezes the lever 54 again, and the lever 54 returns to its original position. The rubber block 55 is again attached to the outside of the contour column 2 to fix the sleeve 3 in the new position. The operation is simple and quick, which improves the efficiency of installation and maintenance.

[0044] Example 3:

[0045] See also Figure 7 - Figure 8As shown, this embodiment is basically the same as the previous embodiment, with the difference that a dustproof assembly 6 is provided on the top of the contour column 2, and the dustproof assembly 6 includes a dustproof cover 61 provided on the top of the contour column 2, and the side plate 64 of the dustproof cover 61 is fixedly connected with a plurality of protrusions 62 evenly distributed on the circumference, and each protrusion 62 is symmetrically provided with at least two semicircular grooves 63. The dustproof cover 61 is used to prevent dust from entering the interior of the contour column 2. During the installation process, the dustproof cover 61 can also play a protective role, preventing debris from entering and falling into the slots provided on the base 1, affecting the normal operation of the device. The protrusion 62 cooperates with the ball 67 to fix the dustproof cover 61 on the top of the contour column 2. When the dustproof cover 61 is buckled on the top of the contour column 2, the ball 67 is stuck with the protrusion 62 under the thrust of the second spring 66, so that the dustproof cover 61 is firmly fixed to the top of the contour column 2, and the semicircular groove 63 is used to cooperate with the ball 67.

[0046] Specifically, the contour column 2 is fixedly connected with a plurality of side plates 64 that are evenly distributed around the circumference, and each side plate 64 is symmetrically fixed with a connecting tube 65. A second spring 66 is provided in each of the two connecting tubes 65, and a ball 67 is slidably connected in each of the two connecting tubes 65. The side plates 64 are used to provide a stable support point for the connecting tube 65 to ensure that the connecting tube 65 can work normally on the contour column 2. The connecting tube 65 is used to provide a stable installation space for the second spring 66 and the ball 67 to ensure that they can work normally in the connecting tube 65. The second spring 66 is used to provide thrust for the ball 67. The elastic force of the second spring 66 ensures close contact between the ball 67 and the protrusion 62 to prevent the dust cover 61 from loosening or falling off during use. The function of the ball 67 is to cooperate with the semicircular groove 63 on the protrusion 62 to fix the dust cover 61 on the top of the contour column 2.

[0047] Furthermore, the inner side of the dust cover 61 fits with the outer side of the end of the contour column 2 , the two ends of the second spring 66 are fixedly connected to the connecting pipe 65 and the sphere 67 respectively, and the outer side of the sphere 67 fits in the semicircular groove 63 .

[0048] As can be seen from the above, when pouring concrete around the base 1, the dust cover 61 is buckled on the ring 13 to cover the slot of the base 1 to prevent debris from falling into it. When the pouring is completed, the dust cover 61 is buckled on the top of the contour column 2. The protrusion 62 on the side plate 64 of the dust cover 61 cooperates with the ball 67. The thrust of the second spring 66 pushes the ball 67 to clamp the protrusion 62, so that the dust cover 61 is firmly fixed to the top of the contour column 2 to play a dust-proof role. When the dust cover 61 needs to be removed, it is only necessary to apply a certain external force to make the ball 67 overcome the thrust of the second spring 66 and escape from the semicircular groove 63 on the protrusion 62, and the dust cover 61 can be removed from the top of the contour column 2.
