Description

Technical Field

[0001] This utility model relates to the field of ceiling speaker equipment technology, and in particular to a ceiling speaker embedded installation anti-fall-off clamping device. Background Technology

[0002] Ceiling speakers, as an important component of public address systems, are used in various public places such as shopping malls, office buildings, schools, and hotels. They play important functions such as information dissemination, background music playback, and emergency broadcasting. Among the installation methods of ceiling speakers, recessed installation has become the first choice for many places because it can be perfectly integrated with the ceiling, does not take up extra space, and is aesthetically pleasing.

[0003] In traditional recessed ceiling speaker installations, simple clips or screws are mainly used for fixing. With clips, the clips are prone to elastic fatigue due to frequent vibrations and changes in temperature and humidity, resulting in a decrease in clamping force and gradual loosening of the speaker. For example, in crowded places such as shopping malls, the vibrations generated by background music playing for a long time and the movement of people will accelerate the aging of the clips. The current solution is to use screws with external connectors to fix them to the wall. Although screw fixing is stronger than the initial tightening effect, there is still a problem that the screws may strip when the ceiling material is not good. Moreover, the installation and disassembly process is relatively cumbersome, which is not conducive to later maintenance and replacement, and thus cannot effectively prevent the speaker from falling off. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a ceiling speaker embedded installation anti-falling clamping device, which aims to improve the problem that when the ceiling material is poor, the screws will strip, making it impossible to achieve a good anti-falling effect.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a ceiling speaker embedded installation anti-fall-off clamping device, including a connecting shell, with square grooves on both the left and right sides of the connecting shell. A speaker device is installed inside the connecting shell, and an electric push rod is rotatably connected to the middle of both the left and right sides of the speaker device. One end of the electric push rod is rotatably connected to a rotating shaft, and a clamping plate is rotatably connected to one side of the rotating shaft. A rotating column is rotatably connected to the rear side of the clamping plate, and the rear side of the rotating column is rotatably connected to the rear side of the outer wall of the speaker device. Two fixing cones are fixedly connected to the opposite sides of the two clamping plates. A heat dissipation mechanism is provided on the rear side of the connecting shell to improve the heat dissipation efficiency inside the device.

[0006] As a further description of the above technical solution:

[0007] The heat dissipation mechanism includes an exhaust fan. The outer wall of the exhaust fan is located on the rear side of the connecting shell. Connecting blocks are fixedly connected to both the upper and lower sides of the exhaust fan. Bolts are threadedly connected to the rear side of the connecting blocks. The front end of the bolts is threadedly connected to the rear side of the connecting shell. An installation groove is provided in the middle of the rear side of the connecting shell. The outer wall of the exhaust fan engages with the installation groove. A processing shell is connected to the front side of the exhaust fan. A filter plate is fixedly connected to the rear side of the inner wall of the processing shell. An absorbent sponge is fixedly connected to the middle of the inner wall of the processing shell. Conveying shells are connected to the left and right ends of the front side of the processing shell.

[0008] As a further description of the above technical solution:

[0009] The heat dissipation mechanism also includes two rubber rings, the inner walls of which are respectively fixedly connected to the front end of the outer wall of the corresponding bolt.

[0010] As a further description of the above technical solution:

[0011] The upper and lower sides of the speaker device are fixedly connected with locking posts, and the upper and lower sides of the inner wall of the connecting shell are provided with locking grooves. The outer wall of the locking post is slidably connected to the locking groove.

[0012] As a further description of the above technical solution:

[0013] A protective ring is fixedly connected to the front end of the outer wall of the speaker device, and the outer wall of the protective ring engages with the inner wall of the connecting shell.

[0014] As a further description of the above technical solution:

[0015] A controller is fixedly connected to the rear of the speaker device, and the controller is electrically connected to the electric push rod and the exhaust fan respectively.

[0016] As a further description of the above technical solution:

[0017] The upper and lower sides of the connecting shell are fixedly connected to connecting seats, and the front side of the connecting seat is provided with mounting holes.

[0018] As a further description of the above technical solution:

[0019] The heat dissipation mechanism also includes two rubber strips, the front sides of which are fixedly connected to the left and right rear ends of the exhaust fan, respectively.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the electric push rod drives one end of the plate to move. However, under the displacement restriction of the rotating column, the plate can rotate around the rotating column as an axis, so that the plate can rotate towards the outer wall of the connecting shell. Thus, under the displacement of multiple fixed cones, it can penetrate into the interior of the wall, achieving the purpose of preventing the speaker equipment from falling off. This avoids the situation of installation falling off when the ceiling material is poor, thereby improving the anti-falling effect.

[0022] 2. In this utility model, by starting the exhaust fan, it can draw in outside air into the processing shell, so that the air can be filtered and adsorbed for moisture. Then, the filtered and dried airflow can be output to the inside of the connecting shell through the conveying shell, which reduces the heat accumulation generated by the equipment inside the connecting shell, thus improving the heat dissipation effect and increasing the service life of the equipment.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of a ceiling speaker embedded installation anti-fall-off clamping device, including a connecting shell 1. Square grooves 3 are provided on both the left and right sides of the connecting shell 1. The square grooves 3 allow a clamping plate 7 to flip out of the connecting shell 1. A speaker device 4 is installed inside the connecting shell 1. Electric push rods 5 are rotatably connected to the center of both the left and right sides of the speaker device 4, allowing a rotating shaft 6 and the clamping plate 7 to move under the drive of the electric push rods 5. One end of the electric push rod 5 is rotatably connected to the rotating shaft 6, and one side of the rotating shaft 6 rotates... A clamping plate 7 is connected, and a rotating column 8 is rotatably connected to the rear side of the clamping plate 7. The rear side of the rotating column 8 is rotatably connected to the rear side of the outer wall of the speaker device 4. However, under the displacement restriction of the rotating column 8, the clamping plate 7 will not move, so that the clamping plate 7 achieves the effect of rotating around the rotating column 8 as an axis. Two fixed cones 9 are fixedly connected to the opposite side of the two clamping plates 7, so that multiple fixed cones 9 can penetrate into the interior of the wall to achieve the clamping effect of preventing detachment. A heat dissipation mechanism 2 is provided on the rear side of the connecting shell 1. The heat dissipation mechanism 2 is used to improve the heat dissipation efficiency inside the device.

[0032] Specifically, by activating the electric push rod 5, one end can drive the rotating shaft 6 and the clamping plate 7 to move. The rotating column 8 restricts the movement of the clamping plate 7, ensuring that the clamping plate 7 will not move, so that the clamping plate 7 can rotate around the rotating column 8 as the axis. As the rotation proceeds, the clamping plate 7 flips towards the outer wall of the connecting shell 1 through the square groove 3. With the connection of multiple fixing cones 9, the fixing cones 9 can penetrate deep into the interior of the installation wall, thereby achieving a stable installation of the speaker device 4 and ensuring that it will not easily fall off. This installation method is suitable for situations where the ceiling material is not good, effectively avoiding the problem of unstable installation and improving the anti-falling effect of the speaker device 4.

[0033] Reference Figure 1 , Figure 2 and Figure 5The heat dissipation mechanism 2 includes an exhaust fan 201. The outer wall of the exhaust fan 201 is located on the rear side of the connecting shell 1. Connecting blocks 202 are fixedly connected to both the upper and lower sides of the exhaust fan 201. Bolts 203 are threadedly connected to the rear side of the connecting blocks 202. By rotating the bolts 203, the heat dissipation mechanism 2 can be disassembled. The front end of the bolts 203 is threadedly connected to the rear side of the connecting shell 1. A mounting groove 209 is provided in the middle of the rear side of the connecting shell 1. The outer wall of the exhaust fan 201 engages with the mounting groove 209. The heat dissipation mechanism 2 can be disassembled by the operation of the exhaust fan 201. The fan 201 is connected to the front of the processing shell 205. The filter plate 206 is fixedly connected to the rear of the inner wall of the processing shell 205. The extracted airflow is filtered and dried by the filter plate 206 and the adsorption sponge 207. The adsorption sponge 207 is fixedly connected to the middle of the inner wall of the processing shell 205. The left and right ends of the front of the processing shell 205 are connected to the conveying shell 208. The airflow then passes through the conveying shell 208 to dissipate heat inside the connecting shell 1. The accumulated heat is discharged through the square groove 3.

[0034] Specifically, by activating the exhaust fan 201, outside air is drawn into the processing housing 205. The air first passes through the filter plate 206 to remove dust particles, ensuring the cleanliness of the incoming air. After being processed by the filter plate 206, the air continues to flow to the adsorption sponge 207, which further adsorbs moisture from the air, thus preventing potential damage to the equipment from dust particles and moisture. After this dual-processed airflow, the airflow is then sprayed through the conveying housing 208 onto the interior of the connecting housing 1, reducing the heat accumulation generated by the equipment inside the connecting housing 1 during operation, thereby improving the heat dissipation efficiency of the equipment and preventing damage due to overheating. In addition, the exhaust fan 201 can be disassembled and installed by rotating the bolt 203, improving the flexibility and convenience of equipment maintenance.

[0035] Reference Figure 1 , Figure 4 and Figure 5 The heat dissipation mechanism 2 also includes two rubber rings 204, the inner walls of which are fixedly connected to the front end of the outer wall of the corresponding bolts 203; a protective ring 10 is fixedly connected to the front end of the outer wall of the speaker device 4, and the outer wall of the protective ring 10 engages with the inner wall of the connecting shell 1; a controller 13 is fixedly connected to the rear side of the speaker device 4, and the controller 13 is electrically connected to the electric push rod 5 and the exhaust fan 201 respectively.

[0036] Specifically, the rubber ring 204 can reduce the rotational damage of the bolt 203 to the connecting block 202, the protective ring 10 can improve the protection of the outer wall of the speaker device 4, and the controller 13, which is electrically connected to the electric push rod 5 and the exhaust fan 201 respectively, can complete the opening and closing of the device.

[0037] Reference Figure 1 , Figure 2 and Figure 3 The upper and lower sides of the speaker device 4 are fixedly connected with locking posts 11, and the upper and lower sides of the inner wall of the connecting shell 1 are provided with locking grooves 12. The outer wall of the locking post 11 is slidably connected to the locking groove 12. The upper and lower sides of the connecting shell 1 are fixedly connected with connecting seats 14, and the front side of the connecting seat 14 is provided with mounting holes 15. The heat dissipation mechanism 2 also includes two rubber strips 16, and the front sides of the two rubber strips 16 are fixedly connected to the left and right ends of the rear side of the exhaust fan 201, respectively.

[0038] Specifically, the sliding connection between the locking post 11 and the locking groove 12 improves the limiting of the speaker device 4. The device can be installed and connected through the connecting seat 14 and the mounting hole 15. The rubber strip 16 can reduce the impact damage to the rear side of the exhaust fan 201 during installation.

[0039] Working principle: When in use, the electric push rod 5 is activated, which drives the rotating shaft 6 and the clamping plate 7 to move. Then, under the displacement restriction of the clamping plate 7 by the rotating column 8, the clamping plate 7 will not move, so it can rotate around the rotating column 8 as the axis. This allows the clamping plate 7 to rotate through the square groove 3 towards the outer wall of the connecting shell 1. Then, with the connection of multiple fixed cones 9, the fixed cones 9 can penetrate into the interior of the installation wall, achieving the purpose of preventing the speaker device 4 from falling off. This avoids the situation of unstable installation when the ceiling material is not good, thus improving the anti-falling effect.

[0040] Furthermore, during device installation, the installation space has a certain capacity, allowing the exhaust fan 201 to draw outside air into the processing housing 205. This air then passes through the filter plate 206 to filter dust particles, and subsequently through the absorbent sponge 207 to absorb moisture, preventing dust particles or moisture from affecting the equipment's operation. The filtered and dried airflow then passes through the conveying housing 208 to spray airflow into the interior of the connecting housing 1, reducing heat buildup caused by the equipment's operation, improving heat dissipation, and thus increasing the equipment's lifespan. The exhaust fan 201 can be disassembled and installed by rotating the bolt 203, thereby improving its flexibility.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
