Description

Technical Field

[0001] This utility model belongs to the field of traffic equipment technology, and in particular relates to a traffic signal light. Background Technology

[0002] Existing traffic lights typically consist of multiple light panels to indicate road traffic flow through different light colors and road directions.

[0003] However, the current traffic lights have a complex structure, making them inconvenient to assemble and requiring a lot of time. In other words, the assembly process of traffic lights composed of multiple light panels is complicated, resulting in low worker efficiency. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model discloses a traffic signal light that can be easily assembled and allows for quick and convenient position adjustment when the traffic signal light is installed on the road.

[0005] The specific technical solution of this utility model is as follows:

[0006] A traffic signal light includes multiple light groups arranged side by side. Each light group includes a lamp holder and a lamp cover. The lamp holder and the lamp cover are detachably connected. A lamp plate is placed inside the lamp holder, and the lamp cover is provided with a light-emitting part.

[0007] Multiple lamp holders are connected by a slide rail, which is slidably fitted with a locking mechanism;

[0008] The locking mechanism includes locking teeth and clamps, which cooperate to install traffic lights. The locking teeth are adjustable and mounted on a slide rail.

[0009] For the assembly of traffic lights, appropriate connection stability is required. In fact, in addition to fulfilling specific functions, traffic lights should also be lightweight. Therefore, if multiple light groups are combined directly through the connection of lamp holders and / or lamp covers, the stability of the traffic lights will be low. Therefore, this application uses slide rails to directly connect multiple light groups, preferably with no gaps between adjacent light groups. This allows the slide rails to connect multiple light groups and also forms a reinforcing component after the multiple light groups are connected, thereby better meeting the connection stability requirements.

[0010] Preferably, the adjustable clamp is mounted on the slide rail, or the clamp and the clamp teeth are detachably connected.

[0011] The position of the clamp moves with the position of the clamp teeth, and there are different ways to set them. Both assembly methods provided in this application can enable the locking mechanism to be well connected with the crossbar of the road intersection to realize the placement of traffic lights.

[0012] Preferably, the locking mechanism further includes a bracket, which is adjustablely positioned on the slide rail;

[0013] The bracket has a first connecting portion and a second connecting portion in the extension direction of the slide rail. The bracket is connected to the locking teeth through the first connecting portion and the second connecting portion. At least one of the first connecting portion and the second connecting portion has a waist-shaped hole for connecting the locking teeth.

[0014] The bracket can improve the connection stability of the locking teeth and better improve the installation stability of the traffic signal light. When one of them has an oblong hole, it can meet the stable connection requirements while maintaining high error. When both have oblong holes, in addition to meeting the stable connection requirements while maintaining high error, it can also achieve a larger angle of light output direction adjustment, thereby better meeting the actual use requirements.

[0015] Preferably, the back side of the lamp holder is provided with two parallel limiting strips, and the slide rail is disposed between the first limiting strip and the second limiting strip.

[0016] The limiting strip one and the limiting strip two have a limiting space for the slide rail, which allows the slide rail to be quickly assembled with each light group. This enables multiple light groups to be connected together quickly using the slide rail. Furthermore, this structure makes it easy to adjust the relative position of the electrical connection between the slide rail and each light group during the assembly process, further improving connection stability and reducing assembly time.

[0017] Preferably, the locking surface of the locking mechanism is parallel to the extension direction of the slide rail, or the locking surface of the locking mechanism is perpendicular to the extension direction of the slide rail.

[0018] The locking surface of the locking mechanism can be adjusted according to the side-by-side orientation of multiple light groups in the traffic signal relative to the horizontal plane to meet the appearance requirements of the traffic signal in actual use.

[0019] Preferably, the slide rail is provided with a locking mechanism at both ends, and the locking mechanism further includes an adjusting bolt, which passes through the locking teeth and is connected to the slide rail;

[0020] At the connection between the adjusting bolt and the locking tooth, a shim is provided between the locking tooth and the slide rail.

[0021] This structure allows for fine adjustments to the light output direction of traffic lights while ensuring their stable installation, thus meeting practical installation requirements.

[0022] Preferably, it also includes a junction box, which is disposed on one side of the slide rail, or is disposed on the slide rail in an adjustable position;

[0023] A circuit board is placed in the junction box, and the circuit board is electrically connected to the lamp panel.

[0024] The junction box can be set at the required location as needed, and can accommodate wire length, as well as the size and thickness of the circuit board, to better meet the power connection requirements.

[0025] Preferably, the junction box includes a box body and a box cover that slide together. The box cover has a limiting part and a snap-fit ​​part. When the box cover completely covers the opening of the box body, the limiting part limits the movement of the box cover, and the snap-fit ​​part snaps into the box body.

[0026] This structure facilitates the opening and closing of the junction box, effectively meets power connection requirements, and provides excellent waterproofing. It is simple in structure and easy to operate.

[0027] Preferably, the back side of the lamp holder has a cavity, and a second circuit board electrically connected to it is disposed on the lamp plate. At least a portion of the second circuit board is located in the cavity, and the end of the cavity has an opening, which is provided with a closure to close the cavity.

[0028] Although the second circuit board is fixed on the lamp panel and electrically connected to it, the position of the second circuit board should not affect the light output of the lamp panel. Therefore, the second circuit board should be located on the back side of the lamp panel, that is, on one side of the cavity. Since the second circuit board may have a relatively large thickness, the lamp holder may have a certain relatively protruding part, which is the location of the cavity. In other words, at least part of the second circuit board is located in the cavity. Thus, the setting of the enclosure helps to prevent rainwater from causing short circuits.

[0029] Preferably, one of the lamp holder and the lamp cover is provided with a waterproof groove with a closed-loop structure, and the other has a waterproof protrusion that cooperates with the waterproof groove.

[0030] This structure effectively prevents water from entering the light assembly.

[0031] Preferably, the lamp holder has a trumpet-shaped structure, and the diameter of the lamp holder gradually increases from the end connected to the slide rail to the end away from the slide rail;

[0032] A heat sink is provided on the side of the lamp holder facing the small diameter of the lamp base, a small lens is provided on the side of the lamp holder facing the large diameter of the lamp base, and a large lens is provided on the lamp base at its large diameter.

[0033] This structure overcomes the defect of uneven light output from low-power lamp panels in existing technologies. This structure uses high-power lamp panels, which better meets the actual needs of use. Moreover, high-power lamp panels are simple to produce and easier to maintain.

[0034] Preferably, the lamp holder has a stepped structure in the circumferential direction, and a second circuit board is disposed in the groove-shaped space formed by the stepped structure, and the second circuit board is electrically connected to the lamp panel.

[0035] This structure enables the stable placement of the second circuit board, avoiding the instability caused by the curved structure of the lamp holder, thus preventing poor contact problems after long-term use.

[0036] Preferably, the light-emitting part of the lamp cover is a transparent mask integrally formed from a transparent material into the lamp cover, or the light-emitting part of the lamp cover has a through-hole structure and is connected to transparent glass.

[0037] The mask or transparent glass can seal the lamp cover, thereby better preventing external impurities from entering the lamp assembly and preventing rainwater from entering the lamp assembly, thus better ensuring the circuit operating environment and improving service life.

[0038] Preferably, the lamp holder or lamp cover is provided with a detachable shielding component in the direction of light emission from the lamp panel.

[0039] The shielding component can provide sun protection and waterproofing.

[0040] Compared with existing technologies, this utility model is easy to install, simple in structure, easy to disassemble, and easy to maintain. It can greatly improve the assembly efficiency of traffic lights while giving them high structural stability. This utility model has a high waterproof rating, which can effectively prevent water from entering the light assembly. In addition, this utility model can adjust the light output direction of the traffic lights, thereby better adapting to the usage requirements of different road intersections.

Detailed Implementation

[0057] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to specific embodiments.

[0058] like Figures 1 to 15As shown, a traffic signal light includes multiple light groups arranged side by side. Each light group includes a lamp holder 1 and a lamp cover 2. The lamp holder 1 and the lamp cover 2 are detachably connected. A lamp disk 3 is placed inside the lamp holder 1, and the lamp cover 2 is provided with a light-emitting part. Multiple lamp holders 1 are connected by a slide rail 4, and the slide rail 4 is slidably engaged with a locking mechanism. The locking mechanism includes a locking tooth 5 and a clamp 6. The locking tooth 5 and the clamp 6 cooperate with each other to hold the traffic signal light. The locking tooth 5 is adjustable in position on the slide rail 4.

[0059] The lamp holder 1 has a built-in decorative edge, eliminating the need for separate screws to fix it. In some technical solutions of this embodiment, the light-emitting part of the lamp cover 2 is a transparent mask integrally formed from a transparent material. Specifically, the mask and the lamp cover 2 are integrally formed, differing only in that they are molded from different materials. That is, according to functional zoning, the non-light-emitting area of ​​the lamp cover 2 is made of opaque material, while the mask portion of the light-emitting area is made of transparent material, thus achieving both waterproofing and light transmission. In other technical solutions of this embodiment, the light-emitting part of the lamp cover 2 has a through-hole structure, and the light-emitting part is connected to transparent glass. The transparent glass is fitted onto the light-emitting part by a waterproof rubber ring to achieve both waterproofing and light transmission. The waterproof rubber ring can be configured with grooves on both the inner and outer rings, thereby simplifying the installation of the transparent glass.

[0060] like Figure 1 , Figure 3 , Figure 8 , Figure 11 As shown, in this embodiment, the light emission direction of each lamp group is consistent. A detachable shielding component 7 is provided on the lamp holder 1 or lamp cover 2 in the direction of light emission from the lamp panel 3. The shielding component 7 can be used for sunshade or waterproofing. The shielding component 7 is connected to the lamp holder 1 or lamp cover 2 by a snap-fit ​​connection; alternatively, it can be connected by bolts. Therefore, the snap-fit ​​connection of the shielding component 7 avoids the use of screws, offering the advantage of a convenient assembly process. In this embodiment, the lamp holder 1 and lamp cover 2 are also detachably connected by a snap-fit ​​connection; alternatively, they can be connected by bolts.

[0061] like Figure 5 As shown, in this embodiment, one of the lamp holder 1 and the lamp cover 2 is provided with a closed-loop waterproof groove 8, and the other has a waterproof protrusion 9 that cooperates with the waterproof groove 8. The waterproof groove 8 can be a circular groove, or a triangular, quadrilateral, or other polygonal groove, characterized by its closed-loop structure to prevent water leakage. Correspondingly, the waterproof protrusion 9 is also a closed-loop structure. In this embodiment, the waterproof groove 8 is provided in the lamp holder 1, and the waterproof protrusion 9 is provided in the lamp cover 2. Thus, waterproofing is achieved between the lamp holder 1 and the lamp cover 2 through the waterproof groove 8 and the waterproof protrusion 9, and a waterproof rubber ring can be placed in the waterproof groove 8 to better meet the waterproofing requirements.

[0062] like Figure 3 As shown, in some technical solutions of this embodiment, the clamp 6 is adjustablely positioned on the slide rail 4. The clamp 6 is typically an arc-shaped structure, and the locking teeth 5 have toothed structures arranged along the arc, forming a clamping space between the clamp 6 and the locking teeth 5. By adaptively adjusting the size of the clamping space between the clamp 6 and / or the locking teeth 5, or by adaptively selecting clamps 6 and locking teeth 5 of appropriate specifications, the crossbar on one side of the road is clamped in the clamping space, thereby realizing the placement of the traffic signal light. In other technical solutions of this embodiment, the clamp 6 and the locking teeth 5 are detachably connected, such as... Figure 2 As shown, in this technical solution, the locking teeth 5 are not connected to the slide rail 4, but are connected to both ends of the locking teeth 5, and their positions are adjusted on the slide rail 4 to meet actual needs.

[0063] Furthermore, such as Figures 8-15 As shown, the locking mechanism further includes a bracket 10, which is adjustablely positioned on the slide rail 4. The bracket 10 has a first connecting portion 11 and a second connecting portion 12 extending along the slide rail 4. The bracket 10 is connected to the locking tooth 5 via the first connecting portion 11 and the second connecting portion 12. At least one of the first connecting portion 11 and the second connecting portion 12 has a slotted hole 13 for connecting the locking tooth 5. Specifically, the bracket 10 can be connected and fixed to the slide rail 4 on the back side of the lamp holder 1, and its position can be adjusted on the slide rail 4. The locking tooth 5 is fixed to the bracket 10, and the locking tooth 5 clamps the crossbar via a clamp 6, thereby achieving the purpose of fixing the signal light. Figure 10 , Figure 14 As shown, when one of the first connecting part 11 and the second connecting part 12 has an oblong hole 13, the stable connection requirement can be met while maintaining high error. When both have oblong holes 13, in addition to meeting the stable connection requirement while maintaining high error, the light output direction can also be adjusted at a larger angle, thereby better meeting the actual use requirements.

[0064] In some technical solutions of this embodiment, such as Figure 2As shown, the slide rail 4 is equipped with locking mechanisms at both ends. Each locking mechanism includes an adjusting bolt 14, which passes through the locking teeth 5 and connects to the slide rail 4. A shim is placed between the locking teeth 5 and the slide rail 4 at the connection point of the adjusting bolt 14 and the locking teeth 5. As can be seen from the above, the locking teeth 5 are fixed to the slide rail 4 using the adjusting bolts 14, and the locking teeth 5 can clamp the crossbar. The clamp 6 is fixed to the locking teeth 5 with screws, thereby holding the light assembly tightly, making the light assembly installation more stable and less prone to slippage, thus achieving the purpose of fixing the traffic light. Each of the locking teeth 5 at both ends of the slide rail 4 is connected to an adjusting bolt 14, and a shim is placed at the location of the adjusting bolt 14. By setting shims of different thicknesses, the light output direction of the traffic light can be finely adjusted. Typically, the locking surface of the locking mechanism is perpendicular to the extension direction of the slide rail 4.

[0065] Therefore, as described above, in this embodiment, the locking surface of the locking mechanism is perpendicular to the extension direction of the slide rail 4. However, depending on actual needs, the locking surface of the locking mechanism can also be set parallel to the extension direction of the slide rail 4. Multiple light groups can be arranged side-by-side vertically or horizontally. Since the traffic lights are actually located in the middle of the road, a locking mechanism is usually used to hold the crossbar. Therefore, the locking surface of the locking mechanism is usually perpendicular to the crossbar. Based on this, depending on the arrangement of the light groups, the locking surface of the locking mechanism has two basic configurations: parallel to the extension direction of the slide rail 4 and perpendicular to the extension direction of the slide rail 4. Of course, in special cases, traffic lights can also be installed on vertical poles, such as traffic lights on one side of the road for pedestrians to cross. In this case, depending on the arrangement of the lights, the locking surface of the locking mechanism also has two basic ways: parallel to the extension direction of the slide rail 4 and perpendicular to the extension direction of the slide rail 4. In this case, unlike the scheme that can use at least one or two or more locking mechanisms to hold the horizontal bar, only one locking mechanism is set in the middle of the slide rail 4.

[0066] In this embodiment, as Figure 3 , Figure 15 As shown, the back of the lamp holder 1 is provided with two parallel limiting strips, namely, a first limiting strip 15 and a second limiting strip 16, and the slide rail 4 is disposed between the first limiting strip 15 and the second limiting strip 16. This structure can well meet the setting requirements of the slide rail 4. The first limiting strip 15 and the second limiting strip 16 are symmetrical with respect to the center line. Therefore, after connecting the slide rail 4, the slide rail 4 is naturally located in the middle of the lamp holder 1, thereby ensuring the connection balance. In this embodiment, the slide rail 4 is made of aluminum, which has good strength and light weight. The slide rail 4 is fixed to the lamp holder 1 by rivets.

[0067] In this embodiment, a junction box 17 is also included, such as... Figure 2 As shown, in one technical solution, the junction box 17 is disposed on one side of the slide rail 4, as... Figure 3 , Figure 8 , Figure 11 As shown, in another technical solution, the wire box 17 is adjustablely positioned on the slide rail 4. In this solution, the wire box 17 is connected to the slide rail 4 via a box base 18. Different assembly methods can be selected according to actual needs. A circuit board 19 is housed in the wire box 17, and the circuit board 19 is electrically connected to the lamp panel 3. The back side of the lamp holder 1 has a cavity 20, and a second circuit board 21 electrically connected to it is provided on the lamp panel 3. At least a portion of the second circuit board 21 is located in the cavity 20, and the end of the cavity 20 has an opening. A closure 22 is provided at the opening to close the cavity 20. The closure 22 can be first snapped onto the slide rail 4 and / or the lamp holder 1, and then connected with screws. Typically, the circuit board 19 in the wire box 17 is connected to an external power source, and then electrically connected to the second circuit board 21, which in turn electrically connects to the lamp panel to achieve light emission from the lamp panel. Figure 5 , Figure 7 , Figure 13 As shown, in circuit board 19 and circuit board 21, one is a power supply board and the other is a terminal block. The power supply board converts 220V AC mains power into a low voltage suitable for the lamp board, and the terminal block is equivalent to a terminal block. Because circuit board 19 and circuit board 21 are set separately in this embodiment, the electrical connection of multiple lamp groups can be effectively realized. Furthermore, according to the specific circuit board specifications, the lamp holder 1 can be further thinned, thereby achieving better weight reduction of the lamp holder 1, which in turn achieves better weight reduction of the lamp group, and ultimately better weight reduction of the traffic signal light. Therefore, in some technical solutions of this embodiment, the AC mains power is first connected to circuit board 19 (which serves as the power supply board), then stepped down and electrically connected to circuit board 2 (which serves as the terminal block) in the lamp holder 1. In other technical solutions of this embodiment, the AC mains power is first connected to circuit board 19 (which serves as the terminal block), and then electrically connected to circuit board 21 (which serves as the power supply board) in each lamp holder 1 for individual voltage reduction.

[0068] like Figure 6 , Figure 7As shown, in this embodiment, the housing 25 has an inlet hole 23 and an outlet hole 24. Waterproof coils are installed in both the inlet hole 23 and the outlet hole 24. The cable extends through the inlet hole 23 and is electrically connected to circuit board 19. The cable exits through the outlet hole 24, passes through the lamp cover 2, and extends into the lamp holder 1, electrically connecting to circuit board 21. In other words, the lamp assembly's incoming wire enters the wiring box 17 through the inlet hole 23 and is electrically connected to circuit board 19 inside the wiring box 17. The wires of circuit board 19 exit through the outlet hole 24 of the housing 25, pass through the back side of the lamp holder 1, and connect to circuit board 21. Then, circuit board 21 is electrically connected to the lamp panel 3, thereby energizing the lamp assembly. In this embodiment, the junction box 17 includes a slidingly fitted box body 25 and a box cover 26. The box cover 26 has a limiting part and a snap-fit ​​part. When the box cover 26 completely covers the opening of the box body 25, the limiting part limits the movement of the box cover 26, and the snap-fit ​​part snaps into the box body 25. Figure 6 As shown, the cover 26 slides up and down relative to the box body 25. When the cover 26 is at its lowest position, that is, when the cover 26 completely covers the opening of the box body 25, the cover 26 and the box body 25 are engaged. Thus, the wire box 17 achieves the connection between the box body 25 and the cover 26 through sliding and engaging methods, which is simple in structure and easy to use.

[0069] like Figures 10-15 As shown, in some technical solutions of this embodiment, the lamp holder 1 has a horn-shaped structure, and the diameter of the lamp holder 1 gradually increases from one end connected to the slide rail 4 to the end away from the slide rail 4; a heat sink 27 is provided on the side of the lamp disk 3 facing the small diameter of the lamp holder 1, a small lens 28 is provided on the side of the lamp disk 3 facing the large diameter of the lamp holder 1, and a large lens 29 is provided on the lamp holder 1 at its large diameter. In this technical solution, the lamp disk 3 is a high-power LED component. During the operation of the traffic signal light, the lamp disk 3 emits light, which is converged into a beam of light with a corresponding angle under the action of the small lens 28. The beam of light is converged into a ring of parallel light by the large lens 29, and then emitted through the mask or transparent glass at the light-emitting part, making the light intensity of the light-emitting surface more uniform and significantly improving the luminous intensity; at the same time, the heat generated by the lamp disk 3 during operation can also be quickly dissipated through the heat sink 27. Usually, the lamp disk 3 has an aluminum substrate, so the aluminum substrate combined with the heat sink 27 can better meet the heat dissipation requirements. In this embodiment, the large lens 29 can be attached to the mask or transparent glass by adhesive, while the small lens 28, lamp plate 3, and heat sink 27 can be fixed together by bolts.

[0070] Furthermore, a stepped structure 30 is provided on the circumference of the lamp holder 1, and a second circuit board 21 is disposed in the groove-shaped space formed by the stepped structure 30. The second circuit board 21 is electrically connected to the lamp panel 3. In this embodiment, the stepped structure 30 is disposed at the lower part of the lamp holder 1. This structure is simple, facilitates the placement of the second circuit board 21, and has a good aesthetic appearance. At the same time, it avoids a low center of gravity and has good structural advantages.

[0071] Therefore, the traffic light in this embodiment has the advantages of simple structure, low material usage, easy installation, and waterproofing. Specifically, the weight of the traffic light in this embodiment is reduced, meeting the specific application requirements of convenient installation. The traffic light has a simple structure, is easy to disassemble, and is easy to maintain. The overall design of this embodiment is fully waterproof, achieving a waterproof rating of IP67. Compared with the shortcomings of existing traffic lights, such as a scattered overall structure and difficult assembly, this embodiment simplifies the structure, greatly reduces the assembly time of the traffic light, and significantly improves the efficiency of worker assembly.

[0072] The above are merely preferred embodiments of this utility model. It should be noted that the above preferred embodiments should not be considered as limitations on this utility model, and the scope of protection of this utility model should be determined by the scope defined in the claims. For those skilled in the art, several improvements and modifications can be made without departing from the spirit and scope of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
