Description

Technical Field

[0001] The present invention relates to the technical field of traffic signal lamps, and more specifically, to a vertical traffic signal lamp that is easy to maintain. Background Art

[0002] Vertical traffic lights are devices used to control road traffic, usually installed at intersections or crosswalks, to indicate when vehicles and pedestrians can pass or stop. Vertical traffic lights play an important role in modern urban traffic management. They can effectively control traffic flow, improve traffic safety and traffic efficiency, and are an indispensable part of the modern transportation system.

[0003] The lamp heads of existing vertical traffic lights are usually installed at high places at intersections, which requires high-altitude operations during maintenance, posing safety hazards. This not only increases the risks for maintenance personnel, but may also affect the efficiency and quality of maintenance work. Especially in bad weather or busy traffic hours, high-altitude operations are more dangerous and may cause traffic jams or accidents. In addition, traditional traffic lights usually rely on natural heat dissipation to reduce the internal temperature of the lamp head, but this method has limited heat dissipation effect. Under continuous operation, the internal temperature of the lamp head may rise, resulting in a decrease in the performance of the light-emitting unit and the control box, and even affecting their lifespan. The lack of an effective heat dissipation structure may also cause frequent failures of traffic lights, increase maintenance costs, and affect traffic management. In addition, the signal indication effect of traditional traffic lights is not good. Under certain weather conditions, such as rainy and snowy weather or strong light, the indication effect of traditional traffic lights may become unclear, making it difficult for drivers to accurately judge traffic signals and increasing the risk of traffic accidents. Summary of the invention

[0004] The present invention aims to overcome the defects of the prior art and provide a vertical traffic signal lamp which is convenient for maintenance.

[0005] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a traffic light, comprising a lamp pole and a lamp holder, the inner surface of the lamp pole having a strip-shaped slide groove; the lamp holder comprising a shell and a plurality of light-emitting units installed on the shell, a mounting frame being fixed to the shell, a strip-shaped slider matching the strip-shaped slide groove being installed on the mounting frame; a locking unit for locking the relative position of the lamp pole and the lamp holder is also installed on the lamp pole.

[0006] Furthermore, the angle between the strip slide groove and the horizontal plane is between 80-88 degrees.

[0007] Therefore, after the lamp head is lowered, the first door panel is opened, and the lamp pole is located at one side of the space inside the lamp head, which does not affect the maintenance of the light-emitting unit and the control box.

[0008] Furthermore, there are three light-emitting units, which are distributed in a row with equal intervals, and three sunshades are installed on the shell.

[0009] Thus, the sunshade can effectively block direct sunlight or other strong light sources to prevent the light-emitting unit from being disturbed, and drivers and pedestrians can clearly see the status of the signal light without being affected by light interference.

[0010] Furthermore, the shell includes a front panel, a back panel, a top panel, a bottom panel and two side panels, and a first door panel is installed on the back panel; the bottom panel has a rectangular opening for the lamp pole to be inserted, and a first abutting vertical plate and a second abutting vertical plate are fixed to the rectangular opening, and both the first abutting vertical plate and the second abutting vertical plate can abut against the lamp pole.

[0011] Therefore, the rectangular opening at the bottom plate can allow the lamp pole to be smoothly inserted, and the first abutting vertical plate and the second abutting vertical plate can be tightly abutted against the lamp pole, thereby ensuring that the connection between the lamp holder and the lamp pole is stable and reliable.

[0012] Furthermore, the first door panel is hinged to the back panel, and a lock is provided on the first door panel.

[0013] Thereby, it is convenient to open the first door panel for maintenance.

[0014] Furthermore, a control box is installed in the shell, the control box has a second door panel, and a control unit is installed in the control box.

[0015] Thereby, the second door panel can be opened to facilitate maintenance of the equipment in the control box.

[0016] Furthermore, a 4G wireless communication unit or a 5G wireless communication unit is also installed in the control box.

[0017] This enables traffic lights to be remotely monitored and controlled.

[0018] Furthermore, the mounting frame is U-shaped, including two connecting blocks and a mounting plate connecting the two connecting blocks, the strip-shaped sliding block is installed on the mounting plate, and the connecting block is fixedly connected to the back plate.

[0019] Furthermore, a bottom flange is fixedly mounted on the bottom end of the lamp pole.

[0020] This makes it easier to install fixed traffic lights.

[0021] Furthermore, a bar signal light source is installed at the lamp pole; the three light emitting units can emit red light, yellow light and green light respectively; the bar signal light source can emit red light, yellow light and green light.

[0022] Therefore, the strip signal light source and the light-emitting unit of the lamp holder light up synchronously, and the signal indication effect is better.

[0023] Further, the locking unit includes a sliding unit and a rotating unit, the sliding unit includes a first abutment block, a stud fixedly connected to the first abutment block, and two plug-in rails connected to the first abutment block; the rotating unit includes a rotating seat, two sides of the rotating seat have slots that cooperate with the plug-in rails, the rotating seat is installed with a rotating cylinder through a bearing, the rotating cylinder has a threaded hole that cooperates with the stud, the rotating seat has a mounting through hole, and a cooling fan is installed at the mounting through hole; the rotating seat has a mounting groove, the mounting groove has a limiting slide rail, the limiting slide rail is installed with a limiting slider, the limiting slider is connected to an arc sliding rod, and the lamp pole has an arc limiting channel that cooperates with the arc sliding rod; the rotating seat has a first groove, a first magnetic plate is installed in the first groove, and the lamp pole has a second groove, and a second magnetic plate that can attract each other with the first magnetic plate is installed in the second groove.

[0024] The rotating seat is thereby rotated so that the first and second magnetic plates attract each other, so that the rotating seat can be stably fixed on the lamp pole, thereby facilitating the lifting and lowering of the lamp head.

[0025] Furthermore, a rotating block with a regular hexagonal cross section is fixed to the rotating cylinder.

[0026] Thereby, it is convenient to use a tool, such as a wrench, to rotate the rotating block, thereby rotating the rotating cylinder.

[0027] Furthermore, the first abutment block has a first positioning column; the rotating seat has a second positioning column; one of the side plates of the shell has a first positioning hole that cooperates with the first positioning column, and the lamp pole has a second positioning hole that cooperates with the second positioning column.

[0028] Furthermore, the first door panel has a plurality of air outlet holes and a rain shield for shielding the plurality of air outlet holes.

[0029] Thereby, the air outlet is convenient for heat dissipation, and the rain shield plays a role of rain shielding.

[0030] Furthermore, the number of each of the first positioning column, the second positioning column, the first positioning hole and the second positioning hole is two; and the first positioning column and the second positioning column are both chamfered.

[0031] This makes it easier to insert the first positioning post into the first positioning hole and the second positioning post into the second positioning hole.

[0032] Furthermore, filters are installed at both ends of the installation through hole; and the cross-sections of the strip-shaped slide groove and the strip-shaped slide block are both rectangular, trapezoidal or T-shaped.

After the lamp head is lowered, the first door panel is opened, and the lamp pole is located on one side of the space inside the lamp head, which does not affect the maintenance of the light-emitting unit and the control box, thereby improving the efficiency and convenience of maintenance work.

[0037] 2. The locking unit of the traffic light of the present application can not only lock the relative position of the lamp pole and the lamp holder to ensure the stability of the traffic light, but also has the effect of active heat dissipation, thereby effectively reducing the internal temperature of the lamp holder and extending the service life of the traffic light.

[0038] 3. The traffic light of the present application has a strip signal light source, which lights up synchronously with the three light-emitting units of the lamp head, so that the signal indication effect is better, which helps to reduce misjudgment and improve traffic safety.

[0053] The locking unit includes a sliding unit and a rotating unit, the sliding unit includes a first abutment block 6.1, a stud 6.2 fixedly connected to the first abutment block 6.1, and two insertion rails 6.3 connected to the first abutment block 6.1; the rotating unit includes a rotating seat 7.1, both sides of the rotating seat 7.1 have slots 7.1.1 that match the insertion rails 6.3, the rotating seat 7.1 is installed with a rotating cylinder 7.3 through a bearing 7.2, the rotating cylinder 7.3 has a threaded hole that matches the stud 6.2, the rotating cylinder 7.3 is fixed with a rotating block 7.4 with a regular hexagonal cross-section, the rotating seat 7.1 has a mounting through hole, and a cooling fan 7.5 is installed at the mounting through hole; the rotating seat 7.1 has a mounting groove, the mounting groove has a limiting slide rail 7.6, and the limiting slide rail 7.6 is installed with a limited A positioning slider 8 is provided, wherein the positioning slider 8 is connected to an arc-shaped slide bar 8.1, and the lamp pole 1 has an arc-shaped limiting channel cooperating with the arc-shaped slide bar 8.1; the rotating seat 7.1 has a first groove, in which a first magnetic plate 7.7 is installed, and the lamp pole 1 has a second groove, in which a second magnetic plate 1.4 capable of attracting the first magnetic plate 7.7 is installed; the first abutment block 6.1 has a first positioning column 6.4; the rotating seat 7.1 has a second positioning column 7.8; one of the side panels of the shell 2.1 has a first positioning hole 2.7 cooperating with the first positioning column 6.4, and the lamp pole 1 has a second positioning hole 1.5 cooperating with the second positioning column 7.8; the first door panel 4 has a plurality of air outlet holes 4.1 and a rain shield 4.2 for shielding the plurality of air outlet holes 4.1.

[0054] There are two of each of the first positioning column 6.4, the second positioning column 7.8, the first positioning hole 2.7 and the second positioning hole 1.5; the first positioning column 6.4 and the second positioning column 7.8 are both chamfered; filters are installed at both ends of the mounting through hole; the cross-sections of the strip slide groove 1.1 and the strip slider 3.1 are both rectangular, trapezoidal or T-shaped; and the bottom plate is provided with a handle portion 2.8.

[0055] Working principle: The traffic lights of this application, such as Figure 1 , 2As shown, in normal use, the traffic light can be used to indicate traffic signals, and the bar signal light source can be used to indicate synchronously with the three light-emitting units above, so that the signal indication effect is better. At this time, because the first abutting vertical plate and the second abutting vertical plate are both abutted against the lamp pole, and the sliding unit and the rotating unit are extended to the longest state they can reach to abut against each other, the traffic light is in a stable state with a relatively high height.

[0056] When a traffic light fails and needs to be repaired or maintained, Figure 4 As shown, the maintenance personnel (sometimes two people are required to cooperate) use a tool to rotate the rotating block so that the first abutting block does not abut the side plate; then as shown in Figure 5 As shown, the rotating seat is rotated, and the first and second magnetic plates attract each other, so that the rotating seat can be stably fixed on the lamp pole. Therefore, since the lamp head is in a lower position (the strip slider is at the lowest end of the strip slide groove, and the lamp head cannot be lowered any further), it is convenient to open the first door panel to maintain the light-emitting unit and the control box in the lamp head. In addition, the lamp pole is located on one side of the space in the lamp head, which reduces the obstruction of the light-emitting unit, making it more convenient for maintenance personnel to maintain the light-emitting unit and the control box.

[0057] The locking unit not only locks the height of the lamp holder, but also allows the air to dissipate heat for the light-emitting unit and the control box. The arc-shaped slide bar, the limit slider and the limit slide rail ensure that when the rotating seat is rotated to a horizontal state, the limit slider and the limit slide groove provide a certain displacement space for the rotating seat in the horizontal direction as the rotating cylinder rotates, which is more conducive to the complete tight contact between the rotating seat and the lamp pole, thereby making the locking of the lamp holder and the lamp pole more stable.

[0058] Although the present invention has been illustrated and described with respect to the preferred embodiments, it will be appreciated by those skilled in the art that various changes and modifications may be made to the present invention without departing from the scope of the present invention as defined by the claims.
