The receiving antenna 601 is installed inside the antenna protective shell 202, so that the antenna can be effectively protected when subjected to external impact, while maintaining good communication performance.

[0040] In summary, by incorporating a protective mechanism 2, including a threaded ring 201 and an antenna protective shell 202, on the upper surface of the housing 1, the durability and impact resistance of the communication equipment in industrial environments are effectively enhanced. The antenna protective shell 202 is fixed to the housing 1 using a threaded connection, providing not only a robust structure and excellent protection against external impacts, but also easy disassembly and replacement, ensuring the maintainability of the equipment. Simultaneously, the outer surface of the antenna protective shell 202 has a vent 203, which protects the antenna without affecting normal signal transmission and reception or antenna adjustment, ensuring stable communication quality. Furthermore, ventilation holes 101 are provided on opposite sides of the housing 1, aiding in heat dissipation and air pressure balance within the equipment, improving its adaptability to high-temperature and high-humidity environments. The overall housing 1 can withstand the risks of use in industrial environments, giving the equipment stronger protective performance.

[0041] refer to Figures 2 to 4 In one embodiment, the housing 1 is provided with a concave plate 205, and slots 215 are provided on opposite sides of the concave plate 205. The inner walls of the two slots 215 are slidably connected with a block 211. The side of the two blocks 211 that are far apart from each other is fixedly connected to the housing 1, and the block 211 is provided with a positioning hole 210.

[0042] A control plate 206 is fixedly installed on the bottom surface of the concave plate 205. Slide openings 207 are provided on opposite sides of the control plate 206. A first spring 214 is fixedly installed on the inner wall of each slide opening 207. Push blocks 213 are fixedly connected to the ends of the two sets of first springs 214 that are far apart from each other. A positioning rod 212 is fixedly installed on the side of the two push blocks 213 that are far apart from each other. The positioning rod 212 is detachably connected to the positioning hole 210.

[0043] In the above embodiment, the recessed plate 205 inside the housing 1 is used to support and fix the control plate 206. The slots 215 on both sides of the recessed plate 205 are slidably connected to the locking blocks 211 fixed on the housing 1, allowing the recessed plate 205 a certain adjustment space within the housing 1 while ensuring stability. The control plate 206 is connected to the push block 213 through the first spring 214 in the sliding port 207. The positioning rod 212 on the push block 213 can cooperate with the positioning hole 210 on the recessed plate 205 to achieve the positioning of the control plate 206. When it is necessary to disassemble or repair the control plate 206, simply pull the positioning rod 212 out of the positioning hole 210, and the push block 213 and the control plate 206 can be ejected by the elastic force of the first spring 214. This facilitates operation, improves the flexibility of the internal structure of the equipment, and also facilitates subsequent maintenance.

[0044] In one example, the inner bottom wall of the sliding opening 207 is provided with a sliding groove 208, and a paddle 209 is slidably connected to the inner wall of the sliding groove 208. The paddle 209 is fixedly connected to the push block 213.

[0045] In the above embodiment, a groove 208 is provided at the bottom of the slide 207 to provide a moving path for the paddle 209. The paddle 209 is closely connected to the push block 213 and works together. When it is necessary to adjust or disassemble the control board 206, the push block 213 can be moved within the slide 207 by moving the paddle 209. The presence of the paddle 209 not only enhances the convenience of operation, but also makes the movement of the push block 213 more stable.

[0046] refer to Figure 3In one embodiment, a through pipe 8 is fixedly embedded on one side of the housing 1, a T-shaped rod 801 is slidably connected to the inner wall of the through pipe 8, a positioning ring 803 is fixedly installed on the inner wall of the through pipe 8, a second spring 802 is fixedly installed on the side of the positioning ring 803 away from the walkie-talkie body, and the second spring 802 is fixedly connected to the T-shaped rod 801.

[0047] In the above embodiment, a through-tube 8 is embedded in the side of the housing 1, and a T-shaped rod 801 can slide smoothly inside the through-tube 8. A positioning ring 803 is also fixedly installed inside the through-tube 8. A second spring 802 is connected to the side of the positioning ring 803 away from the walkie-talkie body, and the other end of the second spring 802 is connected to the T-shaped rod 801. This allows the T-shaped rod 801 to move stably within the through-tube 8, while being subjected to the elastic force of the second spring 802, ensuring the stability and resilience of the structure. When certain adjustments or operations are required on the walkie-talkie, the T-shaped rod 801 can act as an operating lever, achieving specific functions through sliding, while the second spring 802 provides the necessary restoring force, making the operation smoother and more reliable.

[0048] In one embodiment, a first limiting block 7 and a second limiting block 701 are provided on the inner side of the housing 1, and both the first limiting block 7 and the second limiting block 701 abut against the walkie-talkie body.

[0049] In the above embodiment, the inner wall of the housing 1 is provided with a first limiting block 7 and a second limiting block 701. The main function of the limiting blocks is to fix and support the walkie-talkie body, jointly ensuring the stable position of the walkie-talkie body within the housing 1, thus guaranteeing the stability and durability of the device. At the same time, the first limiting block 7 and the second limiting block 701 also have a certain buffering effect, which can reduce the damage caused to the walkie-talkie body 6 by external impacts to a certain extent, thereby improving the stability and reliability of the overall structure.

[0050] In one embodiment, a rubber pad 9 is fixedly installed on the upper end surface of the concave plate 205, and the rubber pad 9 abuts against the bottom surface of the walkie-talkie body.

[0051] In the above embodiment, the rubber pad 9 further enhances the stability and protection of the walkie-talkie body on the concave plate 205. The rubber pad 9 has excellent elasticity and friction, allowing it to fit tightly against the bottom surface of the walkie-talkie body, effectively preventing the walkie-talkie from sliding or shaking on the concave plate 205, maintaining stability even in uneven or vibrating environments. Furthermore, the rubber pad 9 also has a certain cushioning function; when the walkie-talkie is accidentally dropped, it can absorb some of the impact force, reducing damage to the walkie-talkie body 6 and protecting the internal precision components from injury.

[0052] In one embodiment, the concave plate 205 is provided with two pull plates 5, and the two pull plates 5 are fixedly installed on the front and back sides of the control plate 206 respectively.

[0053] In the above embodiment, two pull plates 5 enhance the stability of the control plate 206 within the recessed plate 205. One pull plate 5 is tightly connected to the front of the control plate 206, while the other pull plate 5 is fixedly installed to the back of the control plate 206, ensuring that the control plate 206 will not shift due to vibration or external force within the recessed plate 205, effectively improving the overall structural stability.

[0054] In one embodiment, each of the vent holes 101 is provided with a filter screen 204 inside, and the filter screen 204 is fixedly connected to the inner wall of the vent hole 101.

[0055] In the above embodiments, the filter 204 installed inside each vent 101 prevents dust and other impurities from entering the device and damaging internal electronic components. The filter 204 is tightly fixed to the inner wall of the vent 101 to ensure good sealing and prevent impurities from penetrating. The filter 204 is made of lightweight and durable material, effectively blocking impurities without affecting the normal ventilation of the device.

[0056] In one embodiment, a rubber sleeve 3 is fitted on the outer surface of the housing 1, and the rubber sleeve 3 has a through hole 301 corresponding to the vent hole 101.

[0057] In the above embodiment, the rubber sleeve 3 enhances the protective performance of the housing 1 and the grip of the operator. It fits tightly against the outer surface of the housing 1, providing an additional buffer layer that effectively resists external impacts and friction, protecting the housing 1 and its internal components from damage. Simultaneously, the rubber sleeve 3 corresponds to the through hole 301 opened in the vent 101, ensuring normal ventilation and heat dissipation of the equipment and preventing the rubber sleeve 3 from obstructing airflow.

[0058] In one embodiment, a base 4 is provided below the concave plate 205, and the base 4 is fixedly connected to the bottom surface of the concave plate 205.

[0059] In the above embodiment, the base 4 provides a stable support for the recessed plate 205, ensuring its stability during use. The base 4 and the bottom surface of the recessed plate 205 can be fixedly connected by high-strength adhesives or fasteners such as screws. In addition, the bottom of the base 4 is provided with anti-slip texture, increasing the friction with the placement surface and further improving the stability of the device.
