Description

Technical Field

[0001] This utility model relates to the field of broadcasting equipment technology, and in particular to an incoming line conversion device and a broadcasting device. Background Technology

[0002] In the fields of communications and broadcasting, loudspeakers are indispensable equipment. With the development of technology, the application of loudspeakers is becoming increasingly widespread, including in public places such as restaurants and large facilities such as ships. Loudspeakers can quickly and accurately transmit information, guiding the public in evacuation and shelter actions, and providing strong support for emergency rescue work.

[0003] Currently, loudspeakers are typically mounted on walls or the interior walls of facilities, with the power cables of the broadcasting equipment connected to the loudspeakers. To prevent cable damage, a seal is installed at the junction of the cable and the loudspeaker. Therefore, a large installation space needs to be reserved behind the loudspeaker, resulting in a significant lateral footprint. When the overall space is limited (such as on ships), the lateral space allowed for the loudspeakers is limited. If the above installation method is used, firstly, the seal is inconvenient to install, and in severe cases, the limited lateral space may prevent installation, causing cable damage; secondly, it makes operation difficult for staff, increasing their workload. Utility Model Content

[0004] The purpose of this utility model is to provide an incoming line conversion device and a broadcasting device to solve the problem of the inability to install the sealing component due to limited lateral space, protect the cable, prevent cable damage, and facilitate operation, disassembly and installation, thereby reducing the workload of workers.

[0031] Example 1

[0032] This embodiment provides an input line conversion device, such as... Figure 1 and Figure 2 As shown, this can solve the problem of the inability to install the seal 3 due to limited space, protect the cable, prevent cable damage, and is easy to operate, disassemble and install, which can reduce the workload of workers.

[0033] The incoming line conversion device includes a base 1, a main housing 2, a seal 3, and a cable. The base 1 includes a connected base plate 11 and a support arm 12. The end of the support arm 12 away from the base plate 11 is configured to be mounted on a wall, and the length of the support arm 12 is adjustable along the direction away from the wall. The main housing 2 is mounted on the base plate 11 and is detachably connected to it. The main housing 2 is configured to mount a speaker 4, which is located on the side of the main housing 2 away from the base plate 11 and is detachably connected to it. The speaker 4, the main housing 2, and the base plate 11 are all detachably connected for easy disassembly, installation, and routine maintenance. A through hole 22 is provided on the side of the main housing 2 facing the speaker 4, and a transition hole 21 is provided on the side wall of the main housing 2. A mounting cavity 23 is provided inside the main housing 2, and the through hole 22 communicates with the transition hole 21 through the mounting cavity 23. The seal 3 engages with the adapter hole 21, and the inner cavity of the seal 3 communicates with the mounting cavity 23 through the adapter hole 21. Engaging the seal 3 to the side wall of the main housing 2 reduces the lateral space occupied when installing the speaker 4. The cable enters the mounting cavity 23 through the inner cavity of the seal 3 and is electrically connected to the speaker 4 through the through hole 22.

[0034] When connecting the speaker 4 and the cable, the seal 3 is installed at the adapter hole 21 on the side wall of the main housing 2. The cable then extends from the inner cavity of the seal 3 into the mounting cavity 23 and exits the main housing 2 through the through hole 22, thus connecting the cable to the speaker 4. By opening the adapter hole 21 on the side wall of the main housing 2, the seal 3 can be placed on the side wall of the main housing 2, allowing the cable to enter the mounting cavity 23 through the seal 3 from the side wall of the main housing 2. This reduces the lateral space occupied by the speaker 4, thus reducing the need for mounting space on the back of the speaker 4 and solving the problem of the seal 3 being unable to be installed due to limited lateral space. Furthermore, the large side space of the main housing 2 facilitates the installation of the seal 3, and the operation is simple, making disassembly and installation easy and reducing the workload of workers. In addition, the length of the support arm 12 can be flexibly adjusted according to the actual site size, avoiding existing equipment while making reasonable use of the space.

[0035] For example, seal 3 includes a cable stuffing gland.

[0036] It should be noted that the cross-sectional area of ​​through hole 22 can be changed according to the actual number of cables and the cross-sectional area of ​​the cables.

[0037] In this embodiment, two support arms 12 are provided, and the two support arms 12 are symmetrically arranged about the center of the base plate 11. In other embodiments, more than two support arms 12 may be provided as needed, and the multiple support arms 12 may be spaced apart along the circumference of the base plate 11; this is not limited here.

[0038] Optionally, the cross-sectional shape of the main housing 2 includes circles, rectangles, and polygons. By providing main housings 2 with various shapes, it is possible to install speakers 4 of different shapes.

[0039] Optionally, such as Figure 1 and Figure 2 As shown, the base plate 11 has a second through hole 13, and the main housing 2 has a third through hole 24 on the side facing the base plate 11. The second through hole 13 and the third through hole 24 are directly opposite each other, and the third through hole 24 communicates with the mounting cavity 23 through the second through hole 13. When the speaker 4 and cable connector need maintenance, workers can directly enter the mounting cavity 23 through the second through hole 13 and the third through hole 24 to perform maintenance operations without disassembling the speaker 4, thus reducing procedures and improving work efficiency.

[0040] Optionally, such as Figure 1 and Figure 2 As shown, the main housing 2 has a plurality of first mounting holes 25 spaced apart circumferentially on the side facing the base plate 11, and the base plate 11 has a plurality of second mounting holes 14 spaced apart circumferentially. The incoming line conversion device also includes a first connector (not shown in the figure) and a first fastener (not shown in the figure). When the main housing 2 is installed on the base 1, the main housing 2 abuts against the base plate 11, and the plurality of first mounting holes 25 are aligned with the plurality of second mounting holes 14 one by one. Then, the operator can use through hole two 13 and through hole three 24 to pass the first connector through the first mounting holes 25 and the second mounting holes 14, and thread it with the first fastener. The structure is simple, easy to operate, and easy to disassemble and install.

[0041] For example, the first connector includes a bolt, and the first fastener includes a nut.

[0042] In this embodiment, the main housing 2 has four first mounting holes 25, and the base plate 11 has four second mounting holes 14. In other embodiments, depending on actual needs, two, three, or more first mounting holes 25 may be provided on the main housing 2, and two, three, or more second mounting holes 14 may be provided on the base plate 11; this is not limited here.

[0043] It should be noted that the number of the first mounting holes 25 is the same as the number of the second mounting holes 14.

[0044] Optionally, such as Figure 1 and Figure 2As shown, the main housing 2 has multiple third mounting holes 26 spaced circumferentially on the side facing the speaker 4, and the speaker 4 has multiple fourth mounting holes (not shown in the figure). The input conversion device also includes a second connector (not shown in the figure) and a second fastener (not shown in the figure). When installing the speaker 4, the speaker 4 is abutted against the side of the main housing 2 away from the base plate 11, and the multiple third mounting holes 26 are aligned with the multiple fourth mounting holes one by one. Then, the operator can use through hole one 22 and through hole two 13 to pass the second connector through the third mounting holes 26 and the fourth mounting holes, and thread it with the second fastener. The structure is simple, easy to operate, and easy to disassemble and install.

[0045] For example, the second connector includes a bolt, and the second fastener includes a nut.

[0046] In this embodiment, the main housing 2 has four third mounting holes 26, and the speaker 4 has four fourth mounting holes. In other embodiments, depending on actual needs, two, three, or more third mounting holes 26 may be provided on the main housing 2, and two, three, or more fourth mounting holes may be provided on the speaker 4; this is not limited here.

[0047] It should be noted that the number of the third mounting holes 26 is the same as the number of the fourth mounting holes.

[0048] In some embodiments, the base 1 further includes multiple fasteners. These fasteners are circumferentially spaced on the base plate 11 and are axially rotatable about the base plate 11. A circumferentially protruding edge is provided on the side of the main housing 2 facing the base plate 11. A first fastener has a clamping position that clamps the protruding edge and the base plate 11, and a release position away from the protruding edge. When the main housing 2 is installed on the base 1, the main housing 2 abuts against the base plate 11, and the multiple fasteners are rotated to clamp the fasteners in the clamping position, i.e., the fasteners simultaneously clamp the protruding edge and the base plate 11, thereby connecting the main housing 2 to the base 1. When the main housing 2 is removed, the multiple fasteners are rotated to release the fasteners, at which point the fasteners separate from the protruding edge, thereby releasing the main housing 2 from the base 1 and removing the main housing 2.

[0049] Optionally, the support arm 12 includes a first arm segment and a second arm segment. One end of the first arm segment is mounted on the wall, and the other end is hollow. One end of the second arm segment extends into the first arm segment and is threadedly connected to the inner wall of the first arm segment. The end of the second arm segment away from the first arm segment is connected to the base plate 11. When other equipment passes between the main housing 2 and the wall, the main housing 2 needs to maintain a certain distance from the wall to avoid other equipment. Part of the second arm segment can be screwed out of the first arm segment to increase the length of the support arm 12, thereby facilitating the passage of other equipment. When the lateral space of the site is small, part of the second arm segment can be screwed into the first arm segment to appropriately reduce the length of the support arm 12, thereby reducing the space occupied by the lateral installation of the speaker 4. Furthermore, by flexibly adjusting the length of the support arm 12, the site space can be rationally utilized, preventing interference with the installation of other equipment.

[0050] Example 2

[0051] This embodiment provides a broadcasting device, including a loudspeaker 4 and an input conversion device as described above. The loudspeaker 4 is mounted on the input conversion device, and a cable is electrically connected to the loudspeaker 4 through the input conversion device. The input conversion device can reduce the lateral space occupied by the loudspeaker 4 during installation, thereby reducing the overall space occupied by the broadcasting device, which is beneficial for realizing the electrical connection between the broadcasting device and the cable when space is limited.

[0052] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model.
