Description

Technical Field

[0001] The utility model relates to the technical field of signal detection, in particular to a signal monitoring device which is convenient to adjust. Background Technique

[0002] Frequency modulation, full name "frequency modulation". It is a modulation method that makes the instantaneous frequency of the carrier change according to the change law of the signal to be transmitted. It is a modulation method that makes the instantaneous frequency of the modulated wave change with the modulation signal. The circuit that realizes this modulation method is called a frequency modulator, which is widely used in frequency modulation broadcasting, television sound, microwave communication, phase-locked circuits, sweep frequency meters and other aspects. The basic requirements for a frequency modulator are large frequency modulation deviation, good frequency modulation characteristics, and small parasitic amplitude modulation. The radio wave generated by the frequency modulation method is called a frequency modulated wave, and its basic characteristic is that the oscillation amplitude of the carrier remains unchanged, and the oscillation frequency changes with the modulation signal. Frequency modulation (FM) means that the frequency of the high-frequency carrier is not a constant, but changes within a certain range with the modulation signal, and its amplitude is a constant. Correspondingly, amplitude modulation means that the frequency of the carrier frequency is constant, and its amplitude changes with the modulation signal.

[0003] The frequency modulation broadcast monitoring system is a system that uses modern communication technology and information technology means to monitor, analyze and manage frequency modulation broadcast signals in real time. The system receives frequency modulation broadcast signals, demodulates, decodes and analyzes them, so as to realize the real-time monitoring and management of broadcast content. The frequency modulation broadcast monitoring system is widely used in fields such as radio stations, television stations, and network operators, and is of great significance for ensuring the transmission quality of broadcast signals, maintaining information security, and improving the broadcast service level.

[0004] The existing frequency modulation signal receiver is installed on the wall to receive and decode signals, and then transmits the results. In daily use, it is necessary to frequently plug and unplug the connecting wires of the receiver, and it is also necessary to prevent the connecting wires from being accidentally touched. Therefore, some detection devices have the function of lifting and adjusting, but the stability is not strong enough and they are not a whole. So we propose a new signal monitoring device to solve this problem. Content of the Utility Model

[0026] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0027] It should be noted that all the directional indications in the embodiments of the present application are only used to explain the relative positional relationship and movement conditions between components in a specific posture. If this specific posture changes, the directional indications will also change accordingly.

[0028] In the present application, unless otherwise clearly defined and limited, terms such as "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal connection of two components or the interaction relationship between two components, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0029] The monitoring device receives the FM radio signal, demodulates, decodes, and analyzes it, so as to realize the real-time monitoring and management of the broadcast content.

[0030] In the related art, a frequency modulation signal receiver is installed on a wall to receive and decode signals, and then the results are transmitted. In daily use, the connection wires of the receiver need to be frequently plugged and unplugged, and the connection wires also need to be prevented from being accidentally touched. Therefore, some detection devices have the function of lifting and adjusting, but the stability is not strong enough and they are not an integral whole.

[0031] In order to solve the problems in the related art to a certain extent, the embodiment of the present application provides a signal monitoring device that is convenient to adjust. By forming a fixation between a slide rail 14 with a groove 16 and a connection seat 12 of a receiver 11, it can not only move up and down to adjust the height, but also will not be easily separated.

[0032] The following describes the present application with reference to the accompanying drawings and specific embodiments:

[0033] Combined Figures 1-4 , the embodiment of the present application provides a signal monitoring device that is convenient to adjust, including a monitoring device 1; the monitoring device 1 includes: a connection seat 12 is arranged on the outer wall of a receiver 11; a mounting seat 13 is arranged on the outer wall of the connection seat 12 and is connected to the wall by bolts; a slide rail 14 is arranged on the outer wall of the mounting seat 13; a chute 15 is opened on the outer wall of the connection seat 12; a groove 16 is opened on the outer wall of the slide rail 14; a second limiting block 17 is arranged inside the chute 15; a pin 18 penetrates through the slide rail 14 and the connection seat 12, a first through hole 181 is opened on the connection seat 12, and a second through hole 182 is opened on the slide rail 14.

[0034] When in use, first install the mounting seat 13 on the wall, then connect and fix the connection seat 12 and the receiver 11 by bolts, sleeved the chute 15 on the connection seat 12 on the slide rail 14 of the mounting seat 13, so that the connection seat 12 can slide up and down on the slide rail 14 of the mounting seat 13, and fix it by inserting the pin 18 into the first through hole 181 on the connection seat 12 and the second through hole 182 on the slide rail 14. The groove 16 opened on the slide rail 14 cooperates with the second limiting block 17 installed in the chute 15 to limit the second limiting block 17 in the groove 16, thereby preventing the chute 15 from separating from the slide rail 14 and making all structures form an integral whole.

[0035] Specifically, the model of the receiver 11 is RX-750, which belongs to the prior art.

[0036] In some embodiments, the mounting seat 13, the receiver 11 and the second limiting block 17 are connected by bolts. The second limiting block 17 is fixed to the mounting seat 13 and the receiver 11 by bolts, increasing the strength of the receiver 11 and the second limiting block 17.

[0037] In some embodiments, the slide rail 14 has a convex structure. The setting of the convex structure further enhances the stability between the chute 15 and the slide rail 14.

[0038] In some embodiments, a first limiting block 141 is provided at the top of the slide rail 14, and the first limiting block 141 is connected to the slide rail 14 by bolts. By removing the first limiting block 141, the connecting seat 12 can be moved upward and detached from the slide rail 14, facilitating the connection and fixation between the connecting seat 12 and the mounting seat 13.

[0039] In some embodiments, an auxiliary component 2 is provided on the mounting seat 13. The auxiliary component 2 includes: a connecting block 21 disposed on the outer sidewall of the mounting seat 13; a brake block 22 disposed at one end of the connecting block 21. During the descent of the receiver 11 and the connecting seat 12, the brake block 22 on the connecting block 21 forms friction with the connecting seat 12, slowing down the descent speed of the connecting seat 12. The connecting block 21 can be fixed to the mounting seat 13 by welding.

[0040] In some embodiments, an inclined plate 23 cooperating with the brake block 22 is provided on the outer sidewall of the connecting seat 12. The setting of the inclined plate 23 can increase the frictional force between the brake block 22 and the connecting seat 12, gradually slowing down the descent speed of the inclined plate 23 and the connecting seat 12 until the inclined plate 23 and the connecting seat 12 are stuck with the brake block 22 and cannot continue to descend. At this time, the gap between the second limiting block 17 and the bottom of the groove 16 is smaller than the rubber block 25 in the following text.

[0041] In some embodiments, a shaft body 24 is threadedly connected to the outer sidewall of the mounting seat 13, and the connecting block 21 is sleeved on the shaft body 24 and rotatably connected. The connecting block 21 rotates on the shaft body 24 and is installed on the mounting seat 13 through the shaft body 24. The connecting block 21 has an arc-shaped structure. When the connecting seat 12 descends, it squeezes the lower end of the connecting block 21, causing the upper brake block 22 to closely adhere to the connecting seat 12. The shaft body 24 is connected by two cylinders with different diameters, a large one and a small one. The connecting block 21 is sleeved on the small-diameter cylinder and is threadedly connected to the mounting seat 13.

[0042] In some embodiments, a rubber block 25 is provided at the bottom of the inner wall of the groove 16. The setting of the rubber block 25 is to prevent the second limiting block 17 from hitting the bottom of the groove 16.
