Description

Technical Field

[0001] This application relates to the field of signal gain equipment technology, and in particular to a telescopic signal gain mechanism for a smoke alarm relay. Background Technology

[0002] A signal gain device is an electronic device used to enhance signal strength, improve signal quality, and extend transmission distance. Its main function is to amplify and process weak input signals to achieve a signal level sufficient for the normal operation of subsequent equipment or systems. Signal gain devices are widely used in various communication, electronic equipment, and systems, such as wireless communication systems, broadcast television transmission, radar systems, and sensor networks. By amplifying the signal, the signal quality degradation caused by distance attenuation and noise interference during transmission can be effectively overcome, ensuring that the signal is accurately and stably transmitted to its destination.

[0003] In existing technologies, smoke detectors generate electrical signals when they detect smoke or other abnormal conditions. These signals are usually weak and need to be amplified and transmitted so that they can be received by remote monitoring equipment or alarm systems. Therefore, a signal gain base station is often set up within a certain range to ensure stable information transmission. However, existing signal gain base stations rely heavily on antennas for signal enhancement. These antennas are usually manually adjusted by staff during installation, and their angle and direction cannot be adjusted according to actual conditions during use, which can easily lead to poor signal reception.

[0004] Therefore, we propose a telescopic signal gain mechanism for smoke detector relays to solve the above problems. Utility Model Content

[0013] A further feature of this invention is that the interior of the universal base has two motor slots, and a longitudinal axis servo motor and a transverse axis servo motor are respectively fixedly installed on the inner wall of one side of the two motor slots.

[0014] By adopting the above technical solution, the longitudinal axis servo motor and the transverse axis servo motor are used to drive the longitudinal axis crank and the transverse axis crank to rotate respectively.

[0015] A further feature of this invention is that the receiving mechanism includes a longitudinal crank, a ball joint, a transverse crank, and a linkage rod. The longitudinal crank is fixedly sleeved on the output shaft of the longitudinal servo motor. A longitudinal hole is formed on one side of the longitudinal crank, and a ball joint is rotatably installed inside the longitudinal hole. A transverse crank is fixedly sleeved on the output shaft of the transverse servo motor. A linkage hole is formed on one side of the transverse crank, and a linkage rod is rotatably installed inside the linkage hole.

[0016] By adopting the above technical solution, it is convenient to drive the ball joint and the linkage to rotate through the longitudinal axis crank and the transverse axis crank respectively.

[0017] A further feature of this invention is that a linkage groove is provided on one side of the ball head end of the ball head rod, and a linkage metal block is fixedly installed at one end of the linkage rod, with the linkage metal block slidably installed inside the linkage groove.

[0019] A further feature of this invention is that the antenna assembly includes a telescopic antenna base, an antenna sleeve, and an antenna rod. The other end of the ball-head rod is fixedly mounted with the telescopic antenna base. The antenna sleeve is slidably mounted on the inner side of the telescopic antenna base, and the antenna rod is slidably mounted on the inner side of the antenna sleeve.

[0020] By adopting the above technical solution, it is easy to control the extension and retraction of the antenna assembly, thereby enhancing the strength of the received signal.

[0021] This application includes at least one of the following beneficial technical effects:

[0022] This application utilizes a receiving mechanism consisting of a universal base and a ball joint to adjust the orientation and angle of the antenna assembly according to actual conditions, enabling it to better receive the signal from the smoke alarm and transmit it stably.

[0029] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0030] This application discloses a telescopic signal gain mechanism for a smoke alarm relay, including a mounting base 1 for the telescopic signal gain mechanism for a smoke alarm relay. A signal gain base station 4 is detachably mounted on the inner side of the mounting base 1, and multiple receiving brackets 5 are fixedly mounted on the outer side of the signal gain base station 4. A universal base 6 is fixedly mounted on the inner side of each of the multiple receiving brackets 5. A receiving mechanism is provided on the universal base 6, and an antenna assembly is provided on the receiving mechanism.

[0031] Specifically, four magnetic slots 2 are provided on the bottom inner wall of the mounting base 1, and four magnetic blocks 3 are fixedly installed on the bottom of the signal gain base station 4. The four magnetic blocks 3 are respectively adapted to the corresponding magnetic slots 2, which facilitates the disassembly or installation of the signal gain base station 4.

[0032] Specifically, the surfaces of the four magnetic slots 2 and the four magnetic blocks 3 are all coated with an anti-electromagnetic interference coating to prevent magnetic force from interfering with the signal.

[0033] Specifically, the surface of the signal gain base station 4 is coated with tungsten carbide. The tungsten carbide coating can significantly improve hardness and wear resistance, enhance corrosion resistance, resist high temperature environment, and reduce the coefficient of friction, effectively extending the service life of the signal gain base station 4.

[0034] Specifically, the universal base 6 has two motor slots inside. A longitudinal axis servo motor 7 and a transverse axis servo motor 11 are fixedly installed on the inner wall of one side of the two motor slots, respectively. The longitudinal axis servo motor 7 and the transverse axis servo motor 11 drive the longitudinal axis crank 8 and the transverse axis crank 12 to rotate.

[0035] Specifically, the receiving mechanism includes a longitudinal crank 8, a ball joint rod 9, a transverse crank 12, and a linkage rod 13. The longitudinal crank 8 is fixedly sleeved on the output shaft of the longitudinal servo motor 7. A longitudinal hole is opened on one side of the longitudinal crank 8, and the ball joint rod 9 is rotatably installed inside the longitudinal hole. The transverse crank 12 is fixedly sleeved on the output shaft of the transverse servo motor 11. A linkage hole is opened on one side of the transverse crank 12, and the linkage rod 13 is rotatably installed inside the linkage hole, so that the ball joint rod 9 and the linkage rod 13 can be rotated by the longitudinal crank 8 and the transverse crank 12 respectively.

[0036] Specifically, a linkage groove 10 is provided on one side of the ball head end of the ball head rod 9, and a linkage metal block 14 is fixedly installed on one end of the linkage rod 13. The linkage metal block 14 is slidably installed inside the linkage groove 10, and the ball head rod 9 can be driven to rotate through the linkage rod 13.

[0037] Specifically, the antenna assembly includes a telescopic antenna base 15, an antenna sleeve 16, and an antenna rod 17. The telescopic antenna base 15 is fixedly installed at the other end of the ball head rod 9. The antenna sleeve 16 is slidably installed on the inner side of the telescopic antenna base 15, and the antenna rod 17 is slidably installed on the inner side of the antenna sleeve 16, which facilitates the control of the antenna assembly to extend and retract, thereby enhancing the received signal strength.

[0038] Working principle: When the signal gain base station 4 is in operation, upon receiving a weak signal, it activates the vertical axis servo motor 7 and the horizontal axis servo motor 11. The vertical axis servo motor 7 drives the vertical axis crank 8 to rotate. The rotation of the vertical axis crank 8 causes one end of the ball joint rod 9 to rotate around its own ball joint as the center. The rotation of one end of the ball joint rod 9 causes the antenna assembly to rotate, thereby adjusting its angle. At the same time, the horizontal axis servo motor 11 activates, causing the horizontal axis crank 12 to rotate around the output shaft of the horizontal axis servo motor 11 as the center. The rotation of the horizontal axis crank 12 causes the linkage rod 13 to move. The linkage rod 13 moves through the linkage metal block 14. The ball head end of the movable ball head rod 9 rotates, which drives the antenna assembly to rotate and adjust its orientation for better reception of the smoke alarm signal. When maintenance is required, the signal gain base station 4 can be disassembled for maintenance. At the same time, the length of the antenna assembly can be adjusted to enhance the signal strength. After maintenance and debugging are completed, the four magnetic blocks 3 on one side of the signal gain base station 4 are aligned with the corresponding magnetic slots 2 and then magnetically installed. The surfaces of the four magnetic blocks 3 and the four magnetic slots 2 are all coated with anti-electromagnetic interference coating to prevent magnetic force from affecting the signal.

[0039] With the above structure, the telescopic signal gain mechanism of the smoke alarm relay provided in this application can adjust the orientation and angle of the antenna assembly according to the actual situation, so that it can better receive the signal of the smoke alarm and stably transmit it, thereby increasing the practicality of the device and improving the safety and stability of the smoke alarm. At the same time, the magnetic slot and magnetic block can assist the signal gain base station in disassembly and maintenance, greatly improving the efficiency of maintenance.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
