[0002] Lifting bollards are devices for controlling vehicle traffic. They can be used in conjunction with gate control systems or alone. Lifting bollards are divided into hydraulic lifting and electric lifting. They are specially designed and developed to prevent non-permitted vehicles from forcibly entering sensitive areas. They are highly practical, reliable and safe.

[0003] After searching, the patent document with the authorization publication number CN2644498Y in the related technology discloses a lifting column and a lifting column array, which belongs to road traffic safety equipment. The lifting column includes a column body, a column sleeve, a lifting rope, a sleeve, and a group of pulleys; the column body is installed in the column sleeve and the upper end surfaces of the two are flush; the sleeve is installed below the ground; a pulley is located at the upper end of the side wall of the column sleeve; the lifting rope crosses the pulley, and its fixed end passes through the gap between the column body and the column sleeve and is fixed to the bottom of the column body, and the other end passes through the sleeve and is connected to the lifting rope winding wheel located on the ground through another pulley. The lifting column array includes a plurality of the above-mentioned lifting columns, a main rope and another group of pulleys; the lifting rope of each lifting column passes through a pulley in the same direction and is connected to the main rope, and the main rope is connected to the lifting rope winding wheel. The utility model is difficult to be damaged by vehicles and is also very convenient to use.

[0004] Regarding the above-mentioned related technologies, the utility model applicant believes that there are the following defects:

[0005] 1. Although the above structure is difficult to be damaged by vehicles and is convenient to use, the above column only uses pulleys and ropes to achieve the lifting of the column during the lifting process, which easily causes the main lifting and shaking to deviate and affect the lifting work. At the same time, it also lacks the corresponding warning function. Therefore, when the lifting column is lifting, it cannot promptly remind the surrounding pedestrians and vehicle drivers, which easily leads to the safety hazard of pedestrians or vehicles hitting the lifting column, and safety accidents are prone to occur.

[0006] Therefore, it is necessary to provide a new lifting column to solve the above technical problems. Utility Model Content

[0026] Please refer to Figure 1 , Figure 2 and Figure 3 ,in, Figure 1 The structure of the utility model is shown in FIG. Figure 1 ; Figure 2 The structure of the utility model is shown in FIG. Figure 2 ; Figure 3 The structure of the utility model is shown in FIG. Figure 3 The lifting column comprises: a storage cylinder 1;

[0027] A limiting ring 2, wherein the limiting ring 2 is installed in the storage tube 1, and the top height of the limiting ring 2 is consistent with the top height of the storage tube 1;

[0028] A column 3, wherein the column 3 is disposed in the storage tube 1, and the top of the column 3 passes through the limiting ring 2 and is slidably connected to the limiting ring 2;

[0029] A sealing ring 4, wherein the sealing ring 4 is arranged on the limiting ring 2, and the sealing ring 4 is adapted to the column 3;

[0030] A sliding plate 5, wherein the sliding plate 5 is slidably mounted in the storage tube 1, the sliding plate 5 is located below the bottom of the limiting ring 2, and the bottom end of the column 3 is connected to the top of the sliding plate 5;

[0031] The electric push rod 6 is installed on the bottom inner wall of the storage tube 1 , and the output shaft of the electric push rod 6 is connected to the bottom of the sliding plate 5 .

[0032] Two limiting round rods 7 are installed on the inner wall of the bottom of the storage tube 1 , and the electric push rod 6 is located between the two limiting round rods 7 . The top ends of the two limiting round rods 7 pass through the sliding plate 5 and are connected to the bottom of the limiting ring 2 .

[0033] The sliding plate 5 is provided with two sliding holes, and the limiting round rod 7 passes through the sliding holes and is slidably connected with the sliding plate 5 .

[0034] A mounting tube 8 is fixedly mounted on the inner wall of the bottom of the storage tube 1 , and the mounting tube 8 is located on the left side of the electric push rod 6 . A mounting rod 9 is mounted on the bottom of the sliding plate 5 , and the bottom end of the mounting rod 9 extends into the mounting tube 8 and is slidably connected to the mounting tube 8 .

[0035] The installation tube 8 and the mounting seat 11 can be installed or not according to actual needs. If not installed, the proximity switch 12 can be directly installed on the bottom inner wall of the storage tube 1. At the same time, it is necessary to select a suitable storage tube 1 and the length of the mounting rod 9 according to the actual lifting height of the column 3 to avoid failure to achieve the warning effect.

[0036] A sensing sheet 10 is disposed at the bottom end of the mounting rod 9 , a mounting seat 11 is disposed in the mounting tube 8 , a proximity switch 12 is disposed on the top of the mounting seat 11 , and the proximity switch 12 is matched with the sensing sheet 10 .

[0037] A power source 13 is disposed in the storage tube 1 , and the power source 13 is located on the right side of the electric push rod 6 . A lamp housing 14 is disposed on the top of the column 3 , and a warning light 15 is disposed in the lamp housing 14 .

[0038] The working principle of the lifting column provided by the utility model is as follows:

[0039] The first step: when in use, the electric push rod 6 is started, and the output shaft of the electric push rod 6 drives the sliding plate 5 to telescopically move on the two limiting round rods 7, and the sliding plate 5 can drive the column 3 to move up and down, thereby completing the lifting work, and the two limiting round rods 7 can prevent the column 3 from deviating during the lifting process and affecting the lifting work;

[0040] The second step: the proximity switch 12 is used to control the switch of the sealing ring 4. Therefore, when the sliding plate 5 moves up and down, it will drive the mounting rod 9 and the sensor sheet 10 to move up and down in the mounting tube 8. When the sensor sheet 10 is away from the proximity switch 12, the distance between the two will become larger. When the sensor sheet 10 moves out of the detection range of the proximity switch 12, the proximity switch 12 can automatically turn on and light the warning light 15 through the internal circuit, and then the warning light 15 can illuminate the surroundings to remind pedestrians and vehicles passing by, thereby achieving a warning effect. Similarly, when the sliding plate 5 drives the mounting rod 9 and the sensor sheet 10 to move downward, the sensor sheet 10 will be close to the proximity switch 12. When the proximity switch 12 detects the sensor sheet 10, it automatically turns off the output and turns off the lamp housing 14, thereby achieving energy saving effects and extending the service life of the warning light 15.
