Description

Technical Field

[0001] This utility model belongs to the field of anti-collision post technology, specifically relating to a retractable anti-collision post with light warning function. Background Technology

[0002] Bollards are common safety features widely used in parking lots, residential areas, schools, and other locations to restrict vehicle traffic and protect people and property. Traditional bollards are typically of fixed height, making them inconvenient to use as they cannot be flexibly adjusted to allow vehicle passage.

[0003] With technological advancements, retractable bollards have emerged, capable of raising and lowering according to actual needs. However, most existing retractable bollards lack effective warning functions. In nighttime or low-light conditions, drivers may have difficulty spotting them in time, increasing the risk of collisions and posing a safety hazard. Furthermore, existing retractable bollards may experience jamming or instability during raising and lowering, affecting their normal use. Therefore, it is necessary to improve existing retractable bollards to enhance their safety and performance.

[0004] In view of this, a retractable bollard with a light warning function is proposed to solve the above problems. Utility Model Content

[0005] The present invention aims to solve the technical problem that most of the existing lifting bollards lack effective warning functions and may experience jamming or instability during the lifting process.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A retractable bollard with a light warning function includes:

[0008] A fixed base is fixed or embedded in the ground; the fixed base has a hollow structure inside and a mounting panel at the bottom. A fixing seat and a guide rail are installed on the inner bottom of the fixed base, and the guide rail is set along the height direction of the fixed base.

[0009] The lifting column is guided and slidably assisted by a fixed base. Several sliding channels that are adapted to and guided by guide rails are arranged at equal intervals around the circumference of the lifting column. The sliding channels are set along the height direction of the lifting column and are slidably connected to the guide rails, so that the lifting column can move smoothly up and down within the fixed base. The top of the lifting column is provided with a top cover, and several layers of annular warning light strips are arranged vertically at equal intervals along the edge of the top cover.

[0010] The drive unit is used to drive the lifting column to move up and down within the fixed base. The drive unit includes a motor, a lead screw, and a nut. When the motor is activated, it drives the lead screw to rotate. The rotation of the lead screw is converted into linear motion of the lifting column through the nut, thereby realizing the lifting of the lifting column.

[0011] Preferably, the outer edge of the mounting panel is provided with a number of mounting holes arranged at equal intervals around its circumference, for fixing or embedding the mounting base on the ground by bolts.

[0012] Preferably, the bottom inner wall of the fixed base is provided with a perforated mounting ring A, and the fixed base is fixed to the top of the perforated mounting ring A by bolts. Several guide rails are arranged at equal intervals around the circumference of the fixed base.

[0013] As a preferred option, the warning light strip uses LED beads. The warning light strip is connected to a power source via a wire. The power source can be a built-in battery or an external power source. The LED beads are installed in an annular slot on the outside of the top cover.

[0014] Preferably, the motor is fixedly installed at the bottom of the fixed base, one end of the lead screw is connected to the output shaft of the motor, and the other end is connected to the C-shaped frame installed on the top of the fixed base through a bearing. The nut is threadedly engaged with the lead screw, and a lifting platform is fixedly installed on the nut. The lifting platform cooperates with the guide rod on the C-shaped frame and the C-shaped frame to guide and slide.

[0015] Preferably, the bottom of the lifting column is fixed with a perforated mounting ring B, which is fixed to the top of the lifting platform by screws.

[0016] Preferably, the bottom of the top cover is fixed with a perforated mounting ring C, which is fixed to the perforated mounting ring D on the inner side of the top of the lifting column by screws.

[0017] Preferably, limit switches are installed at both the top and bottom of the fixed base. These limit switches are electrically connected to the control device, which controls the forward and reverse rotation of the motor and the switching of the warning light strip. When the lifting column rises to its highest position or falls to its lowest position, the corresponding limit switch is triggered. Upon receiving the signal, the control device stops the motor's rotation to prevent the lifting column from exceeding its travel range. The control device can be a microcontroller or PLC controller, connected to the motor and warning light strip via signal lines. The control device can also be connected to a remote control system to remotely control the lifting and lowering of the bollard and its warning light functions.

[0018] Compared with the prior art, the technical effects and advantages of this utility model are:

[0019] 1. This retractable bollard with illuminated warning function emits a bright ring-shaped warning light strip at night or in low-light conditions, alerting drivers and effectively reducing the occurrence of collisions. The warning light strip uses LED bulbs, which are energy-efficient, have a long lifespan, and are adaptable to various working environments.

[0020] 2. The mounting base can be easily and quickly fixed or embedded in the ground using mounting holes and bolts. The evenly spaced mounting holes help distribute the fixing force evenly, increasing stability. The hollow structure of the mounting base reduces overall weight and cost, while providing space for internal circuitry and drive mechanisms.

[0021] 3. The combination of motor, lead screw, and nut in the drive unit provides stable driving force, enabling precise lifting control of the lifting column. The matching design of the guide rail and sliding channel ensures the smoothness of the lifting column during the lifting process, avoiding jamming and improving motion accuracy. The design with perforated mounting rings facilitates the installation and fixation of the lifting column to the lifting platform, improving structural strength and stability.

[0022] 4. Limit switches prevent the lifting column from exceeding its travel range, protecting the drive unit and the lifting column from damage and extending the equipment's service life. The control device can use a microcontroller or PLC controller, improving the system's intelligence. It also supports remote control system connections, making operation more flexible and suitable for a wider range of applications. The structural design considers ease of maintenance, facilitating daily inspection and repair. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] The following combination Figures 1 to 8 This application will be described in further detail.

[0034] This application discloses a lifting anti-collision post with light warning function, including a fixed base 1, a lifting post 5, and a driving device 9; the fixed base 1 is fixed or embedded in the ground; the lifting post 5 cooperates with the fixed base 1 to guide and slide; the driving device 9 is used to drive the lifting post 5 to move up and down within the fixed base 1;

[0035] The mounting panel 2 has a plurality of mounting holes 13 arranged at equal intervals around its circumference, for fixing or embedding the fixed base 1 into the ground with bolts. The mounting holes 13 and bolts allow for convenient and quick fixing or embedding of the fixed base 1 into the ground, improving installation flexibility and convenience. The evenly spaced mounting holes 13 help to evenly distribute the fixing force, making the lifting column 5 more stable.

[0036] The fixed base 1 has a hollow internal structure, with a mounting panel 2 at its bottom. A fixed seat 3 and a guide rail 4 are mounted on the inner bottom of the fixed base 1, with the guide rail 4 positioned along the height direction of the fixed base 1. A perforated mounting ring A14 is provided on the inner wall of the bottom of the fixed base 1. The fixed seat 3 is fixed to the top of the perforated mounting ring A14 by bolts. Several guide rails 4 are arranged at equal intervals around the circumference of the fixed seat 3. Several sliding channels 6, adapted to and guide the guide rails 4, are arranged at equal intervals around the circumference of the lifting column 5. The sliding channels 6 are positioned along the height direction of the lifting column 5 and slidably connected to the guide rails 4, allowing the lifting column 5 to move smoothly up and down within the fixed base 1.

[0037] The hollow internal structure of the fixed base 1 reduces overall weight and cost while providing space for the built-in circuitry and drive unit 9. The guide rail 4 ensures smooth movement of the lifting column 5, preventing swaying and improving movement accuracy. The perforated mounting ring A14, secured with bolts, increases the stability of the fixed base 3 and provides support for the guide rail 4.

[0038] The top of the lifting column 5 is provided with a top cover 7, and several layers of annular warning light strips 8 are arranged vertically at equal intervals along the edge of the top cover 7; the warning light strips 8 use LED beads, and the warning light strips 8 are connected to the power supply through wires. The power supply uses a built-in battery or an external power supply, and the LED beads are installed in the annular slot 15 set on the outside of the top cover 7.

[0039] The sliding channel 6 on the lifting column 5 is compatible with the guide rail 4, ensuring smoothness and stability during the lifting process. The warning light strip 8 improves the safety warning effect, and the LED beads have low energy consumption and long lifespan.

[0040] The drive unit 9 includes a motor 10, a lead screw 11, and a nut 12. The motor 10 is fixedly mounted on the bottom of the fixed base 3. One end of the lead screw 11 is connected to the output shaft of the motor 10, and the other end is connected to the U-shaped frame 16 mounted on the top of the fixed base 3 via a bearing. The nut 12 is threadedly engaged with the lead screw 11, and a lifting platform 17 is fixedly mounted on the nut 12. The lifting platform 17 cooperates with the guide rod 18 on the U-shaped frame 16 and the U-shaped frame 16 to guide and slide. When the motor 10 is activated, it drives the lead screw 11 to rotate. The rotation of the lead screw 11 is converted into linear motion of the lifting column 5 through the nut 12, thereby realizing the lifting and lowering of the lifting column 5.

[0041] A perforated mounting ring B19 is fixedly installed at the bottom of the lifting column 5, and the perforated mounting ring B19 is fixed to the top of the lifting platform 17 by screws. A perforated mounting ring C20 is fixedly installed at the bottom of the top cover 7, and the perforated mounting ring C20 is fixed to the perforated mounting ring D21 on the inner side of the top of the lifting column 5 by screws.

[0042] The combination of motor 10, lead screw 11 and nut 12 on the drive device 9 provides a stable driving force, enabling precise lifting control of the lifting column 5.

[0043] The perforated mounting ring B19 facilitates the installation and fixing of the lifting column 5 and the lifting platform 17, ensuring the stability of the lifting platform 17. The perforated mounting rings C20 and D21 are fixed with screws, ensuring the structural strength of the top of the lifting column 5.

[0044] Limit switches are installed at both the top and bottom of the fixed base 1. These limit switches are electrically connected to the control device, which controls the forward and reverse rotation of the motor 10 and the switching of the warning light strip 8. When the lifting column 5 rises to its highest position or falls to its lowest position, the corresponding limit switch is triggered. Upon receiving the signal, the control device stops the rotation of the motor 10 to prevent the lifting column 5 from exceeding its travel range. The control device can be a microcontroller or PLC controller, connected to the motor 10 and the warning light strip 8 via signal lines. The control device can also be connected to a remote control system to remotely control the lifting and lowering of the bollard and its warning light functions.

[0045] Limit switches prevent the lifting bollard 5 from exceeding its travel range, avoiding equipment damage and potential safety risks. The control device, employing a microcontroller or PLC controller, enables precise control and enhances the system's intelligence. Connecting to a remote control system makes the operation of the lifting bollard more flexible and suitable for a wider range of applications.

[0046] The retractable bollard with light warning function has a ring-shaped warning light strip 8 installed on the top of the bollard body 5. In the dark or low-light environment, it can emit a bright light to remind the driver of the presence of the bollard, effectively reducing the occurrence of collision accidents and improving safety.

Limit switches are installed at the top and bottom of the fixed base 1 to prevent the bollard 5 from exceeding its travel range, protecting the drive unit 9 and the bollard 5 from damage and extending the service life of the equipment.

[0049] When the lifting bollard 5 needs to be raised, the control device starts the motor 10 to rotate forward. The motor 10 drives the lead screw 11 to rotate, and the lead screw 11, through the nut 12, drives the lifting platform 17 and the lifting bollard 5 to rise. At the same time, the control device turns on the warning light strip 8 to emit a light warning. When the lifting bollard 5 rises to the highest position, the limit switch at the top is triggered, and the control device stops the rotation of the motor 10. When the lifting bollard 5 needs to be lowered, the control device starts the motor 10 to rotate in reverse, and the lifting bollard 5 descends. When it descends to the lowest position, the limit switch at the bottom is triggered, and the control device stops the rotation of the motor 10. The lifting bollard can also be remotely controlled via a remote control system.
