[0014] The technical solutions in the embodiments will be described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the utility model.

[0015] At the same time, in order to clearly illustrate the technical solutions of the present application, the upper side, lower side, front side, rear side, left side and right side as shown in Figure 1 are defined.

[0016] As shown in Figures 1 to 2 , the present application provides a traffic signal lamp, which comprises a shell and a lamp installed in the shell, and the shell comprises a lamp holder 11 and a mounting plate 12.

[0017] Specifically, the lamp holder 11 is in a boat-shaped semi-enclosed structure to provide stable support and pressure resistance for the signal lamp, especially during installation and use, so that the lamp holder 11 can withstand external impact forces and reduce the influence of external factors on the signal lamp elements.

[0018] The top surface of the lamp holder 11 is provided with four accommodating grooves 111. The mounting plate 12 is arranged on the top of the lamp holder 11, and the mounting plate 12 is provided with a mounting hole 121 in the middle for mounting the signal lamp. The mounting plate 12 is provided with a notch 122 at each corner, which is matched with the accommodating groove 111. Each notch 122 is provided with a first through hole 123 extending in the front-rear direction. Each first through hole 123 is provided with a rotating shaft member 124, which is at least partially arranged in the accommodating groove 111. One end of the rotating shaft member 124 is a light rod, and the other end is a threaded end. The first through hole 123 is provided with an internal thread, so that the rotating shaft member 124 can be threadedly connected with the first through hole 123.

[0019] When the mounting plate 12 is closed on the lamp holder 11, the mounting plate 12 can rotate around the two rotating shaft members 124 at the left end or the right end to achieve opening and closing.

[0020] Through the structure design of the rotating shaft member 124 between the lamp holder 11 and the mounting plate 12, the traffic signal lamp realizes the opening and closing function of the mounting plate 12, greatly simplifies the installation and maintenance process of the signal lamp, and significantly improves the operation efficiency. At the same time, the rotating shaft member 124 structure is arranged in the lamp holder 11 without shaft ears, which is convenient for the embedded installation of the traffic signal lamp. In addition, the structure of the shell is simple, which greatly reduces the production, assembly and maintenance cost.

On the mounting plate 12, a plurality of protrusions 126 are arranged around the mounting hole 121. A clamping gap is formed between the protrusions 126 and the edge 125, so that the external apron plate can be clamped and installed. Through the above setting, the mounting plate 12 does not need to be bent manually, and the protrusions 126 can guide and position the apron plate, so that the installation of the apron plate is more convenient. At the same time, the problem that the apron plate is easy to loosen or fall off in the traditional installation mode is avoided, and the appearance and stability of the whole are improved.

[0022] As shown in Figure 1 and Figure 2 , the lamp holder 11 is provided with a mounting groove 112 at each of the front and rear ends, and a cylindrical connector 113 is arranged in the middle of the mounting groove 112 in the front-rear direction. A plurality of threaded members 114 are arranged in the mounting groove 112, and the shell can be mounted to the external signal lamp base through the connector 113 and the threaded members 114.

[0023] Further, the bottom edge of the mounting groove 112 is provided with a plurality of second through holes 1121, the second through holes 1121 are used for assembling an external decorative plate, so as to improve the appearance diversity and the aesthetic of the signal lamp. Meanwhile, the second through holes 1121 can be used for drainage, so as to improve the waterproof performance of the signal lamp.

[0024] As shown in Figure 2 The length L1 of the flange 115 along the vertical direction is greater than or equal to 0.1 times and less than or equal to 0.2 times of the length L2 of the lamp holder 11 along the vertical direction. Through the above setting, when it rains, the flange 115 can block most of the rain, further improving the waterproof performance of the signal lamp.
