Description

Technical Field

[0001] The utility model relates to the technical field of broadcasting equipment, in particular to a campus broadcasting equipment with high safety. Background Art

[0002] Since the sound energy emitted by natural sound sources is very limited, its sound pressure level decays with the increase of propagation distance. In addition, the influence of campus environmental noise limits the propagation distance of the sound source. Therefore, a sound reinforcement system must be used in public activity places on campus to amplify the sound source signal and ensure that every student can obtain a clearer sound source when playing important notices, get out of class bells, and music during breaks.

[0003] Existing campus broadcasting equipment is often composed of a speaker device and a signal transmission device. Common speaker devices are divided into outdoor and indoor types, and campus broadcasting equipment usually adopts outdoor type.

DETAILED DESCRIPTION

[0023] Reference Figure 1-Figure 5 A campus broadcasting device with high safety includes a broadcasting device shell 1 and a dustproof plate 2. A substrate 13 is fixedly installed on the broadcasting device shell 1, and a plurality of mounting members 14 are fixedly installed on the substrate 13. Fixed shafts 15 are arranged at both ends of the mounting members 14. A convex plate 16 is connected to the bottom end of the substrate 13, and a screw 17 is arranged on the convex plate 16. By fitting a plurality of mounting members 14 and the convex plate 16 to a supporting rod, the fixed shaft 15 and the screw 17 are manually rotated to fix the mounting members 14 while keeping the balance at both ends. At the same time, the screw 17 fixes the convex plate 16 to complete the installation of the broadcasting device. The mounting members 14 and the convex plate 16 fix the broadcasting device in the horizontal and vertical directions at the same time, thereby improving the stability of the installation of the broadcasting device.

[0024] A top cover 7 is installed on the top of the broadcasting equipment shell 1, and a dustproof plate 2 is clamped on the broadcasting equipment shell 1. A plurality of circular holes are opened on the dustproof plate 2, and a plurality of clamping blocks 3 are installed on the bottom of the dustproof plate 2. A first circular hole is opened on the top of the broadcasting equipment shell 1, and a second circular hole with a smaller diameter than the first circular hole is opened at the position where the broadcasting equipment shell 1 and the dustproof plate 2 are clamped. A plurality of connecting strips 8 are installed on the top cover 7, and the top cover 7 includes a plurality of protruding columns. The connecting strips 8 are sleeved on the protruding columns, and the connecting strips 8 are connected to the limiting rings 9. The limiting rings 9 are coaxially arranged with the protruding columns. A plug rod 10 is connected to the bottom end of the connecting strip 8. The diameter of the end of the plug rod 10 away from the connecting strip 8 is smaller than the diameter of the end of the plug rod 10 close to the connecting strip 8. A compression spring 11 is coaxially arranged on the plug rod 10, and the compression spring 11 is connected to an action ring 12. The action ring 12 moves on the plug rod 10. The rod 10 is inserted into the circular hole on the broadcasting equipment housing 1. After the dustproof plate 2 is clamped with the broadcasting equipment housing 1, the circular hole on the broadcasting equipment housing 1 and the vertical circular holes on both sides of the dustproof plate 2 are matched. The rod 10 is inserted into the circular hole on the broadcasting equipment housing 1, and the end of the rod 10 with a smaller diameter enters the second circular hole with a smaller diameter on the broadcasting equipment housing 1. Because the diameter of the action ring 12 is the same as the end with a larger diameter of the rod 10, the action ring 12 cannot enter the second circular hole with a smaller diameter. The action ring 12 is blocked by the second circular hole. At the same time, in the process of inserting the rod 10 into the hole, the end of the rod 10 with a larger diameter squeezes the compression spring 11, and the limiting ring 9 is rotated to make the connecting strip 8 fit the top cover 7. The fixing of the connecting strip 8 and the installation of the dustproof plate 2 are completed by the reaction force of the compression spring 11 and the pressure of the limiting ring 9.

[0025] A water retaining frame 5 is installed on the broadcasting equipment shell 1, and a plurality of guide plates 4 are connected to the water retaining frame 5. The guide plates 4 are distributed in an array on the water retaining frame 5 along the vertical direction. An auxiliary frame 6 is fixedly connected to the bottom end of the broadcasting equipment shell 1. A plurality of strip holes are opened on the auxiliary frame 6. The auxiliary frame 6 includes a slope. The bottom end of the water retaining frame 5 protrudes from the bottom end of the broadcasting equipment shell 1. Rainwater is gathered on the guide plate 4 through the dustproof plate 2. The guide plate 4 is tilted downward. The rainwater gathered on the guide plate 4 slides down onto the auxiliary frame 6 along with the guide plate 4, and is guided by the slope of the auxiliary frame 6 through the strip holes of the auxiliary frame 6 to flow out of the broadcasting equipment shell 1, so as to prevent the broadcasting equipment from being eroded by rainwater and causing a short circuit and an accident.

[0026] The working principle of the utility model is as follows: a water retaining frame 5 is installed on the broadcasting equipment shell 1, and a plurality of guide plates 4 are connected to the water retaining frame 5. The guide plates 4 are distributed in an array on the water retaining frame 5 along the vertical direction. An auxiliary frame 6 is fixedly connected to the bottom end of the broadcasting equipment shell 1, and a plurality of strip holes are opened on the auxiliary frame 6. The auxiliary frame 6 includes a slope. The bottom end of the water retaining frame 5 protrudes from the bottom end of the broadcasting equipment shell 1. A base plate 13 is fixedly installed on the broadcasting equipment shell 1. A plurality of mounting members 14 are fixedly installed on the base plate 13. Fixed shafts 15 are arranged at both ends of the mounting members 14. A convex plate 16 is connected to the bottom end of the base plate 13. A screw 17 is arranged on the convex plate 16. The water is guided out of the broadcasting equipment shell 1 by the cooperation of the guide plate 4 and the auxiliary frame 6. The fixed installation of the broadcasting equipment in different directions is completed by rotating the fixed shaft 15 and the screw 17, thereby improving the stability of the broadcasting equipment.
