Description

Technical Field

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

[0002] Traffic countdown displays are an important component of traffic signal systems. Their main function 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. By providing transparent time information, traffic countdown displays 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 intelligent transportation systems.

[0003] Currently, products on the market have complex structures and are heavy. The display panel is connected to the cabinet by hinges or multiple screws. These connection and fixing methods make it relatively complicated to disassemble and install the display panel. The current operation sequence for maintaining and replacing the display panel unit of a traffic signal countdown display is as follows: first, the screws on the cabinet door need to be unscrewed and the cabinet door needs to be rotated around the hinge to open the cabinet door. Then, multiple screws fixing the display panel need to be removed. Then, the connecting wires need to be disconnected. The operation is then reversed to replace and install the display panel. 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 shell and a rear shell. The front shell and the rear shell are fixedly connected by bolts. A PCB board is installed in the front shell. 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 to the back of the heat dissipation layer at equal intervals. The rear shell 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 traffic lights malfunction, the above solution makes it difficult to quickly disassemble and repair the traffic light display during implementation. It is also inconvenient to operate at heights when maintaining the traffic signal countdown display. Replacing or repairing the traffic countdown display at intersections with high traffic volume may take longer and affect road traffic. Utility Model Content

[0032] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0033] See Figures 1-3 This embodiment discloses a snap-on traffic countdown display, including a display panel 101 and a housing 102, wherein the display panel 101 and the housing 102 are detachably connected;

[0034] The display panel 101 is provided with a hook 103, and the housing 102 is provided with a slot 104 for engaging with the hook 103; the hook 103 has an L-shaped structure, the slot 104 is provided with a positioning groove 105, the bent part of the hook 103 is provided with a positioning block 106 that engages with the positioning groove 105, and the positioning block 106 is provided with a guide arc surface 107;

[0035] The display panel 101 is threaded with a locking bolt 108, and the housing 102 is provided with a threaded hole 110 for engaging with the locking bolt 108.

[0036] In this embodiment, there are multiple hooks 103 and slots 104, and the hooks 103 and slots 104 are correspondingly arranged. After the hooks 103 on the display panel are aligned with the slots 104 on the housing 102 and engaged, the panel is pushed downward with appropriate force. The positioning block 106 on the hook 103 moves into the positioning groove 105, and the hook 103 and slot 104 are engaged. At this time, the locking bolt 108 on the display panel is aligned with the threaded hole 110, thereby accurately positioning the display panel 101. After the locking bolt 108 is screwed into the threaded hole 110, the display panel 101 is fixed. Through the cooperation of the positioning block 106 and the positioning groove 105, the display panel 101 can be effectively prevented from being engaged with the housing 102 by the hooks 103. After being installed in the slot 104, the display panel 101 is displaced horizontally, ensuring its stability after installation. The guide arc surface 107 guides the hook 103, ensuring the accurate positioning of the display panel 101 and laying the foundation for subsequent fixing. In this embodiment, the display panel 101 is positioned by the cooperation of the hook 103 and the slot 104, and then fixed by the locking bolt 108 in a step-by-step manner. Compared with the existing traffic display that directly fixes the display screen with screws, this method simplifies the installation process and avoids the tedious installation caused by repeated adjustments. At the same time, the cooperation of the positioning block 106 and the positioning groove 105 ensures the accuracy of the display panel 101 installation. After fixing, the connection is more stable, effectively resisting external interference such as vehicle vibration and wind, and reducing the risk of loosening.

[0037] In some embodiments, a connector 120 is mounted on the housing 102, and an adjustment groove 121 is provided on the connector. An adjustment knob 122 for conventional fixed light pole or fixed cantilever threaded connection with a traffic fixed pole or other fixed mechanism is installed in the adjustment groove 121. In this embodiment, after the housing 102 is mounted on the traffic fixed pole or other fixed mechanism via the connector 120, when the adjustment knob 122 is released, the housing 102 can rotate in pitch angle or move along the adjustment groove 121 within the adjustment groove 121 to adjust the angle and position; after the knob is tightened, the friction provided by the adjustment knob 122 can lock the housing 102 in the target position.

[0038] In some embodiments, a water-blocking flange structure 109 is provided on the housing 102. In this embodiment, the water-blocking flange structure 109 can effectively prevent rainwater and other liquids from entering the display from the connection between the housing 102 and the display panel 101, providing good waterproof protection for the electronic components installed inside the housing 102, improving the waterproof performance of the traffic countdown display, extending its service life, and enabling it to work stably and reliably under various harsh weather conditions.

[0039] In some embodiments, a waterproof housing 111 is mounted on the display panel 101. In this embodiment, the waterproof housing 111 provides additional waterproof protection in directions not protected by the water-blocking flange structure 109, further enhancing the waterproof capability of the display, preventing damage to the circuits and components on the display panel 101 due to rainwater intrusion, and ensuring the normal operation of the traffic countdown display.

[0040] In some embodiments, a handle 112 is connected to the display panel 101. In this embodiment, by providing the handle 112, it is easier and less strenuous for workers to install, disassemble, and move the display panel 101, improving the ease of operation. Especially when working at heights, it can provide workers with better leverage points, reducing the difficulty of operation and labor intensity.

[0041] In some embodiments, a clamping assembly 113 is slidably installed in the slot 104, and the clamping assembly 113 is used to press the hook 103 onto the slot 104. In this embodiment, after the display panel 101 is installed in place, the clamping assembly 113 slidably installed in the slot 104 can tightly press the hook 103 into the slot 104; the clamping assembly 113 can further enhance the tightness and stability of the connection between the display panel 101 and the housing 102, and prevent the display panel 101 from shifting due to external force during installation, which would prevent the locking bolt 108 from aligning with the threaded hole 110, thus affecting the installation and fixing effect of the display panel 101 and the housing 102.

[0042] In some embodiments, the clamping assembly 113 includes a clamping block 114 and a spring 115. The clamping block 114 is slidably mounted on the slot 104. The clamping block 114 is provided with a connecting groove. The spring 115 is fixedly connected in the connecting groove, and the clamping block 114 is connected to the connecting groove through the spring 115. In this embodiment, when the hook 103 on the display panel 101 is inserted into the slot 104 of the housing 102, the clamping block 114 is pressed upward by the hook 103, and the spring 115 is compressed. The compressed spring 115 presses the hook 103, which has moved to contact the slot 104, onto the limiting groove, thereby further limiting the hook 103 and sealing the slot 104. When it is necessary to remove the display panel 101 from the housing 102, first rotate the locking bolt 108 so that it no longer engages with the threaded hole 110, then move the display panel 101 upward so that the clamping block 114 moves upward. After the spring 115 is further compressed, the hook 103 can be removed from the slot 104, completing the disassembly of the display panel 101. In this embodiment, the clamping block 114 is made of rubber material.

[0043] In some embodiments, a first ball bearing 116 is provided at the end of the hook 103 near the contacting end of the clamping block 114, and a second ball bearing 117 is provided at the end of the hook 103 near the slot 104. In this embodiment, the hook 103 is provided with a first ball groove and a second ball groove, and the first ball bearing 116 and the second ball bearing 117 are respectively rolled in the first ball groove and the second ball groove. By setting the first ball bearing 116 and the second ball bearing 117, when the hook 103 is installed in or removed from the slot 104, the sliding friction generated between the hook 103 and the clamping block 114 and the slot 104 is converted into rolling friction, which significantly reduces the resistance generated during the insertion or removal of the hook 103, making the installation operation smoother and less strenuous; and by setting the first ball bearing 116, the wear of the clamping block 114 during the installation and removal of the hook 103 can be reduced, extending the service life of the clamping assembly 113, while preventing debris generated by friction from entering the display.

[0044] In some embodiments, the end of the clamping block 114 that contacts the hook 103 is provided with a protrusion 118, and the hook 103 is provided with a groove 119 that mates with the protrusion 118. In this embodiment, when the hook 103 is inserted into the slot 104, the clamping block 114 presses the surface of the hook 103 under the action of the spring 115, and the protrusion 118 moves into the groove 119 along with the clamping block 114; the protrusion 118 is made of rubber material, and the protrusion 118 is embedded in the groove 119 to form a lateral limit, preventing the hook 103 from shifting laterally due to vibration or external force such as wind, and further improving the anti-loosening ability of the hook 103.

[0045] In some embodiments, the end of the clamping block 114 that contacts the hook 103 is provided with a third ball groove, in which a third ball is rolled. The hook 103 is provided with a limiting groove that cooperates with the third ball. In this embodiment, when the hook 103 is inserted into the slot 104, the third ball, guided by the ramp at the entrance of the limiting groove, rolls along the wall of the limiting groove into the limiting groove, providing a smooth guiding effect. After the hook 103 is pressed against the slot 104, the third ball falls precisely into the bottom of the limiting groove. The spring 115 pushes the clamping block 114 to make the ball and the limiting groove make tight contact, forming a mechanical limiting and contact surface. When the hook 103 is pulled out by external force, the third ball rolls in the opposite direction along the limiting groove, overcoming the resistance of the spring 115 to achieve smooth separation of the hook 103 and the slot 104.
