Summary of the invention

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a frequency modulation digital audio broadcasting exciter.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an FM band digital audio broadcasting exciter, including an excitation device integrated front frame, a device inner shell is fixed on the surface of the excitation device integrated front frame, a sealing shell is detachably connected to the inner wall of the device inner shell, an outer fixed sleeve is fixed to the inner wall of the sealing shell, a fixing knob is threadedly connected to the inner wall of the outer fixed sleeve, a fixing sleeve is fixed inside the outer fixed sleeve, a fixing pin is fixed inside the device inner shell, and a clamping ring is fixed inside the fixing knob. In the prior art, the FM band digital audio broadcasting exciter is compactly fixed, and the compact design may limit the upgrade and expansion capabilities of the equipment. With the development of technology and the increase in demand, users may find it difficult to upgrade the equipment. At the same time, the compact design may use some components of special shapes or sizes, and these spare parts may not be easy to find on the market, which increases the difficulty and cost of replacement. With the rapid development of technology, compact equipment may soon become obsolete. , needs to be updated, but the compact design may make this process more complicated and expensive. To solve this problem, the utility model adopts a movable fixing device. After the staff installs the internal module of the FM digital audio broadcasting exciter, the staff aligns the sealing plate with the fixing pin and rotates the fixing knob to move the fixing knob downward along the outer fixed sleeve, so that the clamping ring inside the fixing knob contacts the fixing sleeve teeth. After that, the staff continues to rotate the fixing knob to make the clamping ring continue to move downward, so that the fixing sleeve teeth buckle the fixing pin inward, so that the fixing sleeve teeth clamp the fixing pin, and the installation is completed. At the same time, the staff can also adjust the position of the fixing sleeve teeth clamping the fixing pin according to the height of the upgrade module in the future, so that the space inside the sealing shell and the device shell is changed, thereby avoiding the lack of internal space of the equipment due to future upgrades and expansion capabilities of the equipment, making it easier for users to upgrade and expand the equipment, and avoiding the problem of equipment damage caused by internal compactness.

[0006] Preferably, an impact-resistant shell is detachably connected to the surface of the inner shell of the device, an elastic plate is fixed to the inner wall of the impact-resistant shell, limiting columns are fixed at both ends of the inner shell of the device, and an impact-resistant plate is fixed to the inner wall of the impact-resistant shell. In the prior art, the FM digital audio broadcasting exciter contains many precise electronic components, which may be very sensitive to vibration, falling or impact, resulting in the FM digital audio broadcasting exciter being easily damaged when receiving external impact. The compact structural design may not provide sufficient protection for the internal components and lacks necessary buffering or shock-absorbing measures, so that the external force cannot be effectively dispersed and absorbed when impacted. In response to such problems, the utility model adopts a spring plate and an impact-resistant plate. When the device is impacted, the kinetic energy generated by the device is converted into the elastic potential energy of the impact-resistant plate and the spring plate for storage, so that the kinetic energy generated by the device is gradually exhausted, and the accumulated elastic potential energy is converted and released at the same time. With the help of the internal energy consumption between the device and the impact-resistant shell and the internal energy consumption between the limiting column and the spring plate, the kinetic energy generated by the device is further reduced, thereby achieving the improvement of the impact resistance of the device and preventing the device from being damaged by external impact.

[0007] Preferably, a fixed shell is fixed on the surface of the impact-resistant shell, a push button is slidably connected inside the fixed shell, a toothed disk is fixed at the bottom of the push button, a fixed tooth plate is fixed on the inner wall of the fixed shell, a limiting slip ring is fixed on the inner wall of the fixed tooth plate, a pressure plate is slidably connected to the inside of the fixed shell, a dislocation tooth is slidably connected to the circumference of the pressure plate, a secondary tooth plate is fixed on the circumference of the dislocation tooth, a limiting pin is fixed to the bottom of the pressure plate, a supporting spring is fixed on the inner wall of the fixed shell, and the limiting pin is slidably connected to the front frame integrated with the excitation device. In the prior art, the external installation of the FM digital audio broadcasting exciter adopts an impact-resistant shell fixed by bolts. Although it provides a certain degree of protection, this design may bring some inconvenience in replacement and maintenance. Using bolts to fix the shell may require specific tools, and certain skills and time are required for disassembly and reinstallation, which increases the complexity of maintenance work. In some hard-to-reach locations, tightening or loosening the bolts may be very difficult, requiring additional labor and time. Under harsh environmental conditions, such as humid or corrosive environments, bolts may rust more easily, affecting their fastening performance. To address such problems, the utility model fixes the device with a limit pin. When the staff needs to take out the device inside the impact-resistant shell, they press the push button to make the toothed disc push the dislocated teeth downward until the auxiliary toothed plate is disengaged from the fixed toothed plate. At the same time, the dislocated teeth slide to the top along the tooth grooves on the surface of the toothed disc, so that the dislocated teeth drive the pressure plate to rotate slightly. Then the staff releases the push button. Due to the rotation of the pressure plate, the auxiliary toothed plate is offset at an angle. When the support spring pushes the pressure plate back, the auxiliary toothed plate is slid along the gap between the fixed toothed plates with the help of the support spring. At the same time, the dislocated teeth drive the toothed disc and the push button to push upward, so that the limit pin is disengaged from the integrated front frame of the excitation device, so that the device can be removed for maintenance. During installation, the device is sent into the impact-resistant shell, and the push button is pressed to fix the device with the help of the limit pin, so that the staff can disassemble the device more conveniently and quickly, reduce the difficulty of maintaining the device, and improve the user experience.

[0008] Preferably, the surface of the fixing pin is rough, thereby further improving the fastening ability of the fixing sleeve tooth to fix the fixing pin.

[0009] Preferably, the inner diameter of the clamping ring is larger than the diameter of the fixed sleeve teeth, thereby further improving the user's operating experience and making it smoother to operate the clamping ring to clamp the fixed sleeve teeth, thereby improving the user's feel.

[0010] Preferably, a heat dissipation groove is provided at the bottom of the impact-resistant housing, thereby improving the heat dissipation capacity of the device and preventing heat accumulation from causing high temperature damage to the device.

[0011] Preferably, the array of diamond grooves on the surface of the impact-resistant plate is in a honeycomb shape. When impacted, the honeycomb structure can absorb energy through structural deformation, reduce the energy transferred to the inside of the device, and further improve the impact resistance of the impact-resistant plate.

[0012] Preferably, the surface of the push button is covered with a rubber sleeve, and the soft texture of the rubber sleeve can improve the feel when pressing, provide a more comfortable and natural pressing experience, and further enhance the user's feel.

[0013] Preferably, the support spring adopts a double-strand spring. Compared with a single-strand spring, a double-strand spring can withstand a larger load. The design of the double-strand spring can enable the spring to maintain good elasticity and performance after long-term use, thereby extending the service life of the fixed spring.

[0014] Preferably, the bottom of the impact-resistant housing is provided with anti-skid grooves, which help to fix the position of the device when the device is running or subjected to vibration, and prevent accidental collision or falling due to sliding, thereby reducing the risk of the device slipping. Beneficial Effects

[0015] 1. In the prior art, the FM digital audio broadcasting exciter is compact and fixed, and the compact design may limit the upgrade and expansion capabilities of the equipment. With the development of technology and the increase in demand, users may find it difficult to upgrade the equipment. At the same time, the compact design may use some parts of special shapes or sizes. These spare parts may not be easy to find on the market, which increases the difficulty and cost of replacement. With the rapid development of technology, compact equipment may soon become obsolete and need to be replaced, but the compact design may make this process more complicated and expensive. In response to such problems, the utility model adopts a movable fixing device, which allows workers to install the internal module of the FM digital audio broadcasting exciter Finally, the staff aligns the sealing plate with the fixing pin and rotates the fixing knob to move the fixing knob down along the outer fixed sleeve, so that the clamping ring inside the fixing knob contacts the fixing sleeve teeth. Then the staff continues to rotate the fixing knob to make the clamping ring continue to move downward, so that the fixing sleeve teeth buckle the fixing pin inward, and the fixing sleeve teeth clamp the fixing pin, and the installation is completed. At the same time, the staff can also adjust the position of the fixing sleeve teeth clamping the fixing pin according to the height of the upgrade module in the future to change the space inside the sealing shell and the device shell, so as to avoid insufficient internal space of the equipment due to future upgrades and expansion capabilities, making it easier for users to upgrade and expand the equipment, and avoiding the problem of equipment damage caused by internal compactness.

[0016] 2. In the prior art, the FM digital audio broadcasting exciter contains many sophisticated electronic components, which may be very sensitive to vibration, falling or impact, resulting in the FM digital audio broadcasting exciter being easily damaged when subjected to external impact. The compact structural design may not provide sufficient protection for the internal components and lacks the necessary buffering or shock-absorbing measures, thus failing to effectively disperse and absorb external forces when subjected to impact. To address such problems, the utility model adopts a spring plate and an anti-impact plate. When the device is subjected to impact, the kinetic energy generated by the device is converted into the elastic potential energy of the anti-impact plate and the spring plate for storage, so that the kinetic energy generated by the device is gradually exhausted, and the accumulated elastic potential energy is converted and released at the same time. The kinetic energy generated by the device is further reduced by consuming the internal energy between the device and the anti-impact shell and the internal energy between the limit column and the spring plate, thereby improving the impact resistance of the device and preventing the device from being damaged by external impact.

[0017] 3. In the prior art, the external installation of the FM digital audio broadcasting exciter adopts an impact-resistant shell fixed by bolts. Although it provides a certain degree of protection, this design may bring some inconvenience in replacement and maintenance. The use of bolts to fix the shell may require specific tools, and certain skills and time are required for removal and reinstallation, which increases the complexity of maintenance work. In some hard-to-reach locations, tightening or loosening bolts may be very difficult, requiring additional labor and time. In harsh environmental conditions, such as humid or corrosive environments, the bolts may rust more easily, affecting their tightening performance. To address such problems, the utility model fixes the device through a limit pin. When the staff needs to take out the device inside the impact-resistant shell, they press the push button , so that the toothed disc pushes the misaligned tooth to move downward until the auxiliary tooth plate is separated from the fixed tooth plate. At the same time, the misaligned tooth slides to the top along the tooth groove on the surface of the toothed disc, so that the misaligned tooth drives the pressure plate to rotate slightly. Then the staff releases the press button. Due to the rotation of the pressure plate, the auxiliary tooth plate is offset at an angle. When the support spring pushes the pressure plate back, the auxiliary tooth plate is slid along the gap between the fixed tooth plates with the help of the support spring. At the same time, the misaligned tooth drives the toothed disc and the press button to be lifted upward, so that the limit pin is separated from the integrated front frame of the excitation device, so that the device can be removed for maintenance. During installation, the device is sent into the impact-resistant casing and the press button is pressed to fix the device with the help of the limit pin, so that the staff can disassemble the device more conveniently and quickly, reduce the difficulty of maintaining the device, and improve the user experience.
