Description

Technical Field

[0001] This utility model relates to the field of traffic signal technology, specifically a novel snap-on traffic signal. Background Technology

[0002] The main function of traffic signal systems is to provide pedestrians and drivers with a clear time reference by intuitively displaying the remaining time of red, green, or yellow lights, thereby optimizing traffic behavior, improving safety, and increasing traffic efficiency. Traffic countdown light units, by providing transparent time information, balance the collaborative relationship between people, vehicles, and roads, playing a key role in reducing accidents, alleviating congestion, and improving the travel experience. They are an indispensable device in modern urban smart transportation systems.

[0003] Currently, products on the market have complex structures and are heavy. The light-emitting unit is connected to the housing by hinges or multiple screws. These connection and fixing methods make the disassembly and installation of the light-emitting unit relatively complicated. The current operation sequence for maintaining and replacing the light-emitting unit of the traffic signal countdown light-emitting unit is as follows: first, the screws on the housing door need to be unscrewed and the housing door needs to be rotated around the hinge to open the housing door. Then, multiple screws fixing the display board need to be removed. Then, the connecting wires need to be disconnected. The operation is then reversed to replace and install the display board. For example, the patent with announcement number CN214704963U discloses a road traffic signal light learning countdown display (hereinafter referred to as prior art 1), which includes a front housing and a rear housing. The front housing and the rear housing are fixedly connected by bolts. A PCB board is installed in the front housing. A heat-conducting layer is bonded to the back of the PCB board. A heat dissipation layer is bonded to the back of the heat-conducting layer. Heat sinks are fixedly connected at equal intervals to the back of the heat dissipation layer. The rear housing has through holes for the heat sinks to extend out.

[0004] Existing technology 1 can achieve rapid heat dissipation of the PCB board during implementation, extending the service life of the PCB board; however, when the traffic signal light malfunctions, the above solution makes it difficult to quickly disassemble and repair the traffic light emitting unit during implementation; it is inconvenient to operate at heights when maintaining the traffic signal countdown emitting unit, and replacing or repairing the traffic countdown emitting unit at intersections with high traffic volume may take longer and affect road traffic. Utility Model Content

[0005] The purpose of this utility model is to provide a new type of snap-on traffic signal light, which can solve the problems of complicated disassembly and installation of the light-emitting unit and the housing, and inconvenience of maintenance and repair in the existing traffic countdown display technology.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A new type of snap-on traffic signal light includes a light-emitting unit and a housing, wherein the light-emitting unit and the housing are detachably connected;

[0008] The light-emitting unit includes a water-blocking cover and a control circuit unit connected to the water-blocking cover. The water-blocking cover is provided with a limiting structure, and the housing is provided with fixing bolts for cooperating with the limiting structure. The limiting structure includes a limiting groove and a positioning groove communicating with the limiting groove.

[0009] The end of the limiting groove away from the positioning groove is provided with a stepped structure.

[0010] Preferably, a guide post is installed on the housing, and a wire groove for communicating with the outside is provided inside the guide post.

[0011] Preferably, the housing is provided with a plurality of mounting slots.

[0012] Preferably, the housing is provided with a plurality of slots.

[0013] Preferably, the water-blocking cover is provided with a water-blocking flange.

[0014] Preferably, the water-blocking cover is provided with a guide arc surface.

[0015] Preferably, the housing is equipped with a positioning mechanism for engaging with the positioning groove.

[0016] Preferably, the positioning mechanism includes a tension spring and a movable part, the movable part being slidably connected to the housing, and the movable part being connected to the housing via the tension spring.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] Compared to existing traffic lights that are fixed with multiple screws, this invention greatly simplifies the assembly and disassembly process through the ingenious combination of fixing bolts and limiting structures. During installation, only simple moving, rotating, and pushing operations are needed to sequentially engage the positioning and limiting grooves of the water shield with the fixing bolts, thus achieving positioning and fixation of the water shield without repeatedly tightening multiple screws. During disassembly, after loosening the fixing bolts, rotating the water shield allows the positioning grooves to re-engage with the fixing bolts, separating the light-emitting unit from the housing. This design significantly reduces the time required for installation and disassembly, making it particularly suitable for high-altitude operations and emergency maintenance scenarios at busy intersections, significantly reducing the impact of equipment maintenance on traffic.

[0033] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0034] See Figures 1-5 This embodiment discloses a novel snap-on traffic signal light, including a light-emitting unit 101 and a housing 102, wherein the light-emitting unit 101 and the housing 102 are detachably connected;

[0035] The light-emitting unit 101 includes a water-blocking cover 103 and a control circuit unit 104 connected to the water-blocking cover 103. The water-blocking cover 103 is provided with a limiting structure 105, and the housing 102 is provided with a fixing bolt 106 for cooperating with the limiting structure 105. The limiting structure 105 includes a limiting groove 107 and a positioning groove 108 communicating with the limiting groove 107.

[0036] The end of the limiting groove 107 away from the positioning groove 108 is provided with a stepped structure.

[0037] In this embodiment, there are multiple limiting structures 105 and fixing bolts 106, and the limiting structures 105 and fixing bolts 106 are arranged one-to-one along the circumferential direction of the water-blocking cover 103. When it is necessary to install the light-emitting unit 101 onto the housing 102, the water-blocking cover 103 is first initially aligned with the housing 102, so that the fixing bolts 106 threaded onto the housing 102 move into the positioning grooves 108 provided on the water-blocking cover 103. Then, the water-blocking cover 103 is rotated, and the cooperation between the limiting groove 107 and the threaded post structure in the fixing bolt 106 can limit and guide the rotating waterproof housing. After the fixing bolt 106 contacts the end of the limiting groove 107 away from the positioning groove 108, the light-emitting unit 101 moves to the predetermined position. At this time, after rotating the fixing bolt 106 to press the waterproof shell onto the housing 102, the waterproof shell and the control circuit unit 104 can be installed on the housing 102. When the fixing bolt 106 presses the waterproof shell onto the housing 102, it will fit tightly with the stepped structure, avoiding installation deviation and increasing the friction and contact area between the fixing bolt 106 and the limiting groove 107, which greatly enhances the stability of the connection between the light-emitting unit 101 and the housing 102. During the installation of the light-emitting unit 101, the step-by-step operation involves first positioning it using the limiting mechanism and the fixing bolt 106, and then fixing it with the fixing bolt 106. Compared with the prior art method of directly fixing the display mechanism with screws, this method simplifies the installation process of the light-emitting unit 101 and avoids the cumbersome and time-consuming installation caused by repeatedly adjusting the installation position of the light-emitting unit 101. Loosen the fixing bolt 106 so that it is loosened in the limiting groove 107, and then rotate the waterproof shell in the opposite direction so that the positioning groove 108 moves to the position corresponding to the fixing bolt 106, thereby releasing the limiting effect of the fixing bolt 106 on the light-emitting unit 101. At this point, the light-emitting unit 101 can be easily removed from the housing 102, completing the disassembly operation and facilitating the inspection and replacement of components such as the control circuit unit 104 inside the light-emitting unit 101. In this embodiment, the width of the limiting groove 107 is smaller than the diameter of the positioning groove 108. The control circuit unit 104 is a conventional control device in the prior art (such as XRCHD-B-4-SW (3500-V1) and RX300-3-SW-2RA (SH3700-V1). The functions and structures of the control circuit unit 104 and the light-emitting unit will not be described in detail here.

[0038] In some embodiments, a guide post 109 is mounted on the housing 102, and a wire groove 110 for communicating with the outside is provided inside the guide post 109. When the display screen is running, the control circuit unit 104 needs to connect to various lines such as power supply and control signals. The guide post 109 and the wire groove 110 provide a fixed and orderly arrangement space for these wires. During installation, the wires can pass orderly through the guide post 109 along the wire groove 110, avoiding messy tangling of wires inside the housing 102, making the internal wiring layout clearer, facilitating installation, and meeting the requirements of traffic signal equipment for neat and standardized wiring.

[0039] In some embodiments, the housing 102 is provided with a plurality of mounting grooves 111. In this embodiment, the mounting grooves 111 are strip-shaped groove structures. The design of the strip-shaped groove structure allows the housing 102 to be adapted to a variety of common fasteners such as bolts and screws. Installers can flexibly choose the appropriate fixing method when installing the housing 102 onto traffic fixed poles or other fixed mechanisms conventional fixed light poles or fixed cantilever arms according to the actual installation environment and needs. Moreover, during the later maintenance of traffic lights, if it is necessary to adjust the installation position or replace the installation components, the mounting grooves 111 of the strip-shaped groove structure facilitate the disassembly and reinstallation of common fasteners such as bolts and screws.

[0040] In some embodiments, the housing 102 is provided with a plurality of slots 112. By providing the slots 112, the overall weight of the traffic light can be significantly reduced while ensuring the structural strength of the housing 102. The lighter weight not only reduces transportation costs but also makes installation and disassembly operations easier and less strenuous, especially during high-altitude installation and maintenance, reducing the labor intensity of workers and improving work safety; furthermore, the slots 112 increase the contact area between the surface of the housing 102 and the air, forming a good air circulation channel and improving heat dissipation performance.

[0041] In some embodiments, the water-blocking cover 103 is provided with a water-blocking flange 113. In this embodiment, the water-blocking flange 113 on the water-blocking cover 103 can effectively prevent rainwater, snow water and other liquids from entering the interior of the light-emitting unit 101. In rainy or humid environments, the flange structure changes the direction of water flow, causing rainwater to flow down along the edge of the flange and preventing it from penetrating to the connection between the light-emitting unit 101 and the control circuit unit 104.

[0042] In some embodiments, the water shield 103 is provided with a guide arc surface. By providing this guide arc surface, raindrops blown onto the water shield 103 from the front can be guided, allowing rainwater to slide off the guide arc surface more quickly and preventing water accumulation. This not only avoids corrosion of the equipment surface caused by long-term rainwater residue, but also prevents residual rainwater from freezing and expanding in low-temperature environments, thus preventing damage to the equipment structure and further improving the durability and reliability of the traffic light under different climatic conditions.

[0043] In some embodiments, a positioning mechanism 114 for cooperating with the positioning groove 108 is installed on the housing 102. In this embodiment, a sliding groove is provided on the housing 102, and the positioning mechanism 114 is slidably installed in the sliding groove. When the fixing bolt 106 enters the positioning groove 108, the positioning mechanism 114 will move into the sliding groove under the pressure of the water-blocking cover 103, so that the waterproof housing can be initially positioned by the cooperation of the positioning groove 108 and the fixing bolt 106. When the fixing bolt 106 contacts the end of the limiting groove 107 away from the positioning groove 108, the positioning groove 108 rotates with the waterproof housing to the position corresponding to the positioning mechanism 114. Once the positioning mechanism 114 moves into the positioning groove 108, it indicates that the light-emitting unit 101 has reached the predetermined installation position, thus assisting in the positioning of the waterproof shell. Furthermore, the positioning mechanism 114, once inside the positioning groove 108, can further limit the position of the light-emitting unit 101, preventing the waterproof shell from rotating along the limiting groove 107 under its own weight or external force when the worker tightens the fixing bolt 106. This would prevent the light-emitting unit 101 from being improperly installed, resulting in skewed display content or unstable connection. This further improves the accuracy and reliability of the installation.

[0044] In some embodiments, the positioning mechanism 114 includes a tension spring 115 and a moving part 116. The moving part 116 is slidably connected to the housing 102, and the moving part 116 is connected to the housing 102 via the tension spring 115. In this embodiment, when the fixing bolt 106 enters the positioning groove 108, the moving part 116 moves into the slide groove under the pressure of the water-blocking cover 103. The tension spring 115 is stretched, allowing the waterproof housing to be initially positioned through the cooperation of the positioning groove 108 and the fixing bolt 106. When the fixing bolt 106 contacts the end of the limiting groove 107 away from the positioning groove 108, the positioning groove 108 rotates with the waterproof housing to a position corresponding to the moving part 116. After the moving part moves into the positioning groove 108 under the force provided by the tension spring 115, it indicates that the positioning mechanism is in operation. The light unit 101 has reached the predetermined installation position, and the positioning mechanism 114 can further limit the light-emitting unit 101 after moving into the positioning groove 108. When it is necessary to remove the light-emitting unit 101, first loosen the fixing bolt 106 so that it is loose in the limiting groove 107, then press the waterproof shell and rotate it in the opposite direction. The positioning groove 108 moves back to the position corresponding to the fixing bolt 106, releasing the limitation of the fixing bolt 106 on the light-emitting unit 101. During the reverse rotation of the waterproof shell, the moving part 116 moves back into the sliding groove under the pressure of the waterproof shell to avoid affecting the rotation of the waterproof shell.

[0045] In some embodiments, the movable part 116 is provided with a ball groove, in which a ball is rolledly connected, and the slide groove is provided with a guide slope that cooperates with the ball. In this embodiment, by setting the ball to cooperate with the guide slope, the sliding friction during the sliding process of the movable block can be transformed into rolling friction, which greatly reduces the resistance when the movable block slides. During installation, it is easier and less strenuous for the operator to push the light-emitting unit 101 to rotate; during disassembly, rotating the light-emitting unit 101 makes the operation of moving the movable block to the slide groove smoother, significantly improving the smoothness of the entire disassembly and assembly process and reducing the wear between the movable block and the waterproof shell.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.
