Description

Technical Field

[0001] This utility model relates to the field of explosion-proof loudspeaker technology, specifically to the wireless signal receiving antenna structure of a horn explosion-proof loudspeaker. Background Technology

[0002] The wireless signal receiving antenna of a horn explosion-proof loudspeaker is a key component for communication in special environments, commonly used in flammable and explosive locations such as chemical plants and coal mines. It can stably receive wireless signals, ensuring the loudspeaker accurately transmits instructions and warning information. Its design must be adapted to explosion-proof requirements, maintaining reliable signal reception in complex environments to support safe communication in hazardous scenarios.

[0003] Utility model patent CN221151556U discloses a horn loudspeaker, which includes a base frame assembly, a horn mounting assembly, a rotating locking assembly, and a horn horn. The horn mounting assembly is mounted on the base frame assembly and can tilt and rotate on the base frame assembly. The rotating locking assembly is mounted on the base frame assembly and connected to the horn mounting assembly. The horn horn is mounted on the horn mounting assembly. This horn loudspeaker, by rotatably mounting the horn mounting assembly on the base frame assembly, allows the horn horn to rotate through the rotation of the horn mounting assembly. Simultaneously, the rotating locking assembly secures the horn horn, thereby achieving adjustable sound angle for the horn horn. This meets the needs of different users for horn angle adjustment, resulting in better sound flow and propagation efficiency.

[0004] The component connection method of this horn loudspeaker requires the disassembly of multiple connectors during maintenance and replacement, which involves many steps and is not convenient. In view of this, we propose a wireless signal receiving antenna structure for the horn explosion-proof loudspeaker. Utility Model Content

[0005] The purpose of this invention is to provide a wireless signal receiving antenna structure for a horn explosion-proof loudspeaker, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: The wireless signal receiving antenna structure of the horn explosion-proof loudspeaker includes a loudspeaker body, a tail seat at the rear of the loudspeaker body, an antenna assembly magnetically attached to the tail end of the tail seat, a mounting groove on the tail end face of the tail seat, the antenna assembly including a mounting base embedded in the mounting groove, several antennas mounted at the tail of the mounting base, and an isolation cover covering the tail seat and the outer side of the mounting base, an iron sheet embedded at the bottom of the mounting groove, a magnetic block embedded at the head end face of the mounting base corresponding to the position of the iron sheet, a first convex ring on the outer peripheral surface of the tail seat, an end post at the tail end of the mounting base, a second convex ring on the outer peripheral surface of the end post, the head end of the isolation cover magnetically attached to the tail end face of the first convex ring, and the tail end of the isolation cover tightly bonded to the head end face of the second convex ring.

[0007] Preferably, a plurality of spring pins are provided at the bottom of the mounting groove, and a plurality of contact terminals are installed at the head end face of the mounting base corresponding to the position of the spring pins; In this configuration, the spring pin contacts the contact terminal, enabling an electrical connection between the antenna assembly and the speaker body, ensuring stable signal transmission.

[0008] Preferably, anti-foolproof protrusions are provided on both the left and right sides of the top of the mounting groove, and a pair of positioning grooves are provided on the mounting base corresponding to the position of the anti-foolproof protrusions. When the mounting base is embedded into the mounting groove, the anti-foolproof protrusions extend into the positioning grooves. In this setting, the anti-fooling protrusion cooperates with the positioning groove to prevent the mounting base from being installed in the wrong direction and to ensure that all components are accurately aligned.

[0009] Preferably, an iron ring is embedded at the tail end face of the first convex ring, the isolation cover is an elastic gel structure, the first end of the isolation cover is provided with a first convex edge, and a magnetic ring is tightly bonded to the inner end face of the first convex edge, and the first convex edge is attracted to the iron ring by the magnetic ring. In this configuration, the magnetic ring and the iron ring plate are attracted to each other, so that the first end of the isolation cover is stably connected to the first convex ring, which facilitates installation and separation.

[0010] Preferably, the tail end of the isolation cover is provided with a second protruding edge, and the second protruding edge is tightly bonded to the head end face of the second protruding ring; In this configuration, the second convex edge is tightly bonded to the second convex ring, enhancing the connection and sealing of the tail end of the isolation cover and improving the protective effect.

[0011] Preferably, the tail end of the end post is provided with a prism, and a plurality of hinge seats are fixed on the outer peripheral surface of the prism, and the antenna is hinged to the hinge seats. In this setup, the antenna is hinged to a hinge mount, allowing for flexible adjustment of the antenna angle to accommodate different signal reception needs.

[0012] Preferably, when the antenna assembly is installed, the first end of the isolation cover first contacts the first convex ring, at which time the mounting base has not yet been embedded into the mounting groove; In this configuration, the first end of the isolation cover contacts the first protruding ring, which provides protection for the connection points during the initial installation phase.

[0013] Preferably, when the antenna assembly is pulled outward, the mounting base first separates from the tailstock. At this time, the isolation cover undergoes elastic deformation under the magnetic attraction of the magnetic ring, so that the isolation cover still plays an isolation role between the tailstock and the mounting base until the deformation of the isolation cover reaches the upper limit and separates from the first convex ring. In this setup, the isolation shield undergoes elastic deformation during disassembly and maintains continuous isolation, reducing the impact of the external environment on the connection points.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. The wireless signal receiving antenna structure of this horn explosion-proof loudspeaker is connected to the tail mount through a magnetic adsorption structure. During maintenance and replacement, it is not necessary to disassemble multiple connecting parts with tools. Only appropriate external force is needed to separate the mounting base from the tail mount. The whole process has fewer operation steps, which can reduce the time and manpower required for maintenance and replacement, and at the same time reduce the possibility of damage to other components due to disassembly, making it easier to maintain and replace the antenna assembly. 2. The wireless signal receiving antenna structure of this horn explosion-proof loudspeaker, when used in an environment containing explosive gases requiring explosion protection, utilizes an isolation cover. During antenna assembly disassembly, the cover undergoes elastic deformation under the magnetic attraction of the magnetic ring, remaining between the tailstock and the mounting base to provide isolation. During antenna assembly installation, its head first contacts the first convex ring, providing advance protection. Thus, the isolation cover provides continuous protection during antenna assembly disassembly and installation, reducing the risk of explosive gases entering the connection points and improving the safety of the device in explosion-proof environments.

Detailed Implementation

[0016] 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. Example

[0017] Please see Figures 1-5 The wireless signal receiving antenna structure of the horn explosion-proof loudspeaker includes a loudspeaker body 100 made of aluminum alloy. The rear end of the loudspeaker body 100 is provided with a tail seat 110 made of engineering plastic. The tail end of the tail seat 110 is magnetically attached to the antenna assembly 200. This installation method facilitates the quick assembly and disassembly of the antenna assembly 200. The tail end face of the tail seat 110 is provided with a mounting groove 111, which provides positioning space for the installation of the antenna assembly 200. The antenna assembly 200 includes a mounting base 210 embedded in the mounting groove 111 and several antennas 220 installed at the rear end of the mounting base 210. The mounting base 210 is made of ABS plastic and serves to support the antennas 220.

[0018] like Figure 3 and Figure 5As shown, in this utility model, an iron sheet 113 is embedded at the bottom of the mounting groove 111. The iron sheet 113 is made of ordinary carbon structural steel. A magnetic block 215 is embedded at the first end face of the mounting base 210 corresponding to the position of the iron sheet 113. The magnetic block 215 is made of neodymium iron boron. The iron sheet 113 and the magnetic block 215 cooperate to realize the magnetic connection between the tail seat 110 and the mounting base 210, enhancing the stability of the connection. Several spring pins 112 are provided at the bottom of the mounting groove 111. The spring pins 112 are made of copper alloy and have good conductivity. Several contact terminals 214 are installed at the first end face of the mounting base 210 corresponding to the position of the spring pins 112. The contact terminals 214 are made of brass and gold-plated. The contact between the spring pins 112 and the contact terminals 214 realizes the electrical connection between the antenna assembly 200 and the speaker body 100, ensuring signal transmission.

[0019] like Figure 3 and Figure 5 As shown, specifically, anti-foolproof protrusions 114 are provided on both the left and right sides of the top of the mounting groove 111. The anti-foolproof protrusions 114 are integrally formed with the tail seat 110 and are made of the same material. A pair of positioning grooves 216 are provided on the mounting seat 210 corresponding to the position of the anti-foolproof protrusions 114. When the mounting seat 210 is inserted into the mounting groove 111, the anti-foolproof protrusions 114 extend into the positioning grooves 216, which can prevent the mounting seat 210 from being installed in the wrong direction and ensure that the spring pin 112 and the contact terminal 214 are accurately connected.

[0020] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the mounting base 210 further includes an end post 211 at its tail end, which is integrally formed with the mounting base 210. The end post 211 also includes a prism 212 at its tail end, which is made of stainless steel to improve structural strength. Several hinge seats 213 are fixed on the outer circumferential surface of the prism 212. The hinge seats 213 are made of metal, and the antenna 220 is hinged to the hinge seats 213, allowing the antenna 220 to rotate around the hinge seats 213, which facilitates the adjustment of the receiving angle of the antenna 220. In this embodiment, the wireless signal receiving antenna structure of the horn explosion-proof loudspeaker is used as follows: First, align the mounting base 210 with the mounting groove 111, so that the anti-fooling protrusion 114 corresponds to the positioning groove 216. Then, insert the mounting base 210 into the mounting groove 111. At this time, the iron piece 113 and the magnetic block 215 attract each other, and the spring pin 112 contacts the contact terminal 214, completing the connection and electrical conduction between the antenna assembly 200 and the tail seat 110. Next, according to the actual signal reception requirements, adjust the angle of the antenna 220 through the hinge structure between the antenna 220 and the hinge seat 213. Finally, when disassembly is required, apply appropriate external force to separate the mounting base 210 from the tail seat 110. Example

[0021] To prevent accidents caused by electrical sparks resulting from sudden connection or interruption of electrical connections during the disassembly and installation of the antenna assembly 200, such as... Figures 1-6 As shown, an isolation cover 230 is installed on the outside of the tailstock 110 and the mounting base 210. The isolation cover 230 is made of silicone rubber, which has good elasticity and sealing performance and can play a role in isolation and protection. A first protruding ring 115 is provided on the outer peripheral surface of the tailstock 110. The first protruding ring 115 is integrally formed with the tailstock 110. A second protruding ring 217 is provided on the outer peripheral surface of the end post 211. The second protruding ring 217 is integrally formed with the end post 211. The first end of the isolation cover 230 is magnetically attracted to the tail end face of the first protruding ring 115, and the tail end of the isolation cover 230 is tightly bonded to the first end face of the second protruding ring 217, so that the isolation cover 230 can be stably installed on the outside of the tailstock 110 and the mounting base 210.

[0022] like Figure 3 , Figure 5 and Figure 6 As shown, in this embodiment, the isolation cover 230 is an elastic gel structure. The first end of the isolation cover 230 has a first protruding edge 231, which is integrally formed with the isolation cover 230. A magnetic ring 233, made of ferrite material, is tightly bonded to the inner end face of the first protruding edge 231. An iron ring piece 116, made of low-carbon steel, is embedded at the tail end face of the first protruding ring 115. The first protruding edge 231 is attracted to the iron ring piece 116 by the magnetic ring 233, ensuring a stable connection between the first end of the isolation cover 230 and the first protruding ring 115 and facilitating separation. The tail end of the isolation cover 230 has a second protruding edge 232, which is integrally formed with the isolation cover 230. The second protruding edge 232 is tightly bonded to the first end face of the second protruding ring 217, enhancing the sealing performance between the tail end of the isolation cover 230 and the end post 211.

[0023] Specifically, when installing the antenna assembly 200, the first end of the isolation cover 230 first contacts the first convex ring 115. At this time, the mounting base 210 has not yet been embedded in the mounting groove 111, which can protect the installation part in advance. When the antenna assembly 200 is pulled out, the mounting base 210 first separates from the tail seat 110. At this time, the isolation cover 230 undergoes elastic deformation under the magnetic attraction of the magnetic ring 233, so that the isolation cover 230 still plays an isolation role between the tail seat 110 and the mounting base 210 until the deformation of the isolation cover 230 reaches the upper limit and separates from the first convex ring 115, ensuring continuous protection during disassembly.

[0024] In this embodiment, during installation, the wireless signal receiving antenna structure of the horn explosion-proof loudspeaker is such that the first end of the isolation cover 230 first contacts the iron ring 116 on the first convex ring 115 through the magnetic ring 233, thus achieving early protection. Then, the mounting base 210 is inserted into the mounting groove 111 to complete the connection. The second convex edge 232 at the tail end of the isolation cover 230 is tightly bonded to the second convex ring 217, forming complete isolation. During disassembly, the mounting base 210 first separates from the tail base 110. The isolation cover 230 undergoes elastic deformation due to the attraction of the magnetic ring 233, continuing to isolate the two until the deformation reaches its upper limit and then separates from the first convex ring 115. Throughout the entire process, the isolation cover 230 always plays a protective role.

[0025] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
