AI Technical Summary
The existing signal generator may automatically start the heat dissipation fan in severe cold environments, resulting in continuous low temperature inside the signal generator, affecting the working stability, and requiring manual start of the heat dissipation fan.
A stable mechanism with bimetallic sheet is designed, which automatically starts and stops the heat dissipation fan through temperature changes, and uses metal heat conduction sheets and connecting blocks to transfer heat. The bimetallic sheet is bent due to temperature changes, so that the negative electrode block comes into contact with the positive electrode block, and controls heat dissipation. The fan is turned on, ensuring that it operates at high temperatures and stops at low temperatures.
It realizes that the signal generator does not accidentally start the heat dissipation fan in a low temperature environment, ensures the normal operation of the electrical components, and improves the working stability and service life of the signal generator.

Description
Technical Field
[0001] The utility model relates to the technical field of signal generators, in particular to a signal generator with a stabilizing mechanism. Background Art
[0002] A signal generator is a device that can provide electrical signals of various frequencies, waveforms, and output levels. It is used as a test signal source or excitation source when measuring the amplitude characteristics, frequency characteristics, transmission characteristics, and other electrical parameters of various telecommunication systems or telecommunication equipment, as well as when measuring the characteristics and parameters of components. Signal generators, also known as signal sources or oscillators, are widely used in production practice and the field of science and technology. Various waveform curves are represented by trigonometric function equations. A circuit capable of generating a variety of waveforms, such as a triangular wave, a sawtooth wave, a rectangular wave (including a square wave), and a sine wave, is called a function signal generator. A Chinese patent discloses a signal generator with a stabilizing mechanism (authorization announcement number: CN219876734U). The patent describes that when the machine body starts to work, the machine body generates a large amount of heat during operation, and then the heat dissipation fan device operates to absorb the heat in the machine body through the heat dissipation port of the machine body and discharge it through the exhaust hole on the baffle, thereby discharging the heat in the machine body, reducing the heat loss to the machine body, thereby improving the stability of the machine body operation and extending the service life of the machine body. However, the heat dissipation fan of the above patent needs to be manually started to work normally, or the heat dissipation fan is started at the same time when the power is started, which may cause the fan to start in a relatively cold environment, thereby causing the inside of the signal generator to continue to remain in a low temperature state, so that the signal generator cannot work normally, affecting the working stability of the signal generator. Therefore, a signal generator with a stabilizing mechanism is provided to solve the problems raised in the above background technology. Summary of the invention
[0003] The purpose of the utility model is to provide a signal generator with a stabilizing mechanism to solve the problems raised in the above background technology.
[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] As a further solution of the utility model: wherein, a handle is installed on the signal generator body, and rubber layers are provided at the corners of the two groups of protection frames.
[0007] As a further solution of the utility model: wherein, the housing of the signal generator body is provided with a vent, and the vent is coaxially arranged with the heat dissipation fan.

[0010] As a further solution of the utility model: wherein, a height adjustment rod is spirally connected to the mounting block, and the positive electrode block is mounted on the tail end of the height adjustment rod.
[0011] Compared with the prior art, the beneficial effects of the utility model are:
[0012] When in use, the protective frame is sleeved on both sides of the signal generator body to align the heat dissipation fan with the vent, and then the substrate is attached to the high-temperature component generated when the signal generator body works, and the mounting block is installed on one side of the substrate. When the temperature of the high-temperature component inside the signal generator body is too high, the heat will be transferred to the bimetallic strip through the substrate. The bimetallic strip will deform and bend due to the high temperature, so that the negative electrode block will be attached to the positive electrode block, and then the heat dissipation fan will be turned on and powered, so that the heat dissipation fan starts to work, so that the electrical components inside the signal generator body can be cooled, the temperature of the electrical components inside the signal generator body is reduced, and the stability of the signal generator body is improved. When the temperature inside the signal generator body is normal, the bimetallic strip will return to its original state, so that the negative electrode block will no longer be connected to the positive electrode block, and then the heat dissipation fan will stop working. The above structure prevents the signal generator from turning on the heat dissipation fan in a low temperature environment, so that the electrical components inside the signal generator body can work normally even at low temperatures, thereby improving the working stability of the signal generator.

[0021] Furthermore, when the temperature inside the signal generator body 1 is normal, the bimetallic strip 206 will return to its original state, so that the negative electrode block 208 will no longer be connected to the positive electrode block 209, thereby stopping the cooling fan 201 from working.
[0022] Preferably, a handle 101 is installed on the signal generator body 1, and rubber layers are provided at the corners of the two sets of protection frames 2.
[0023] The setting of the handle 101 makes it easy to pick up the signal generator body 1, and the corners of the protective frame 2 are provided with rubber layers to prevent the signal generator body 1 from colliding with external components. The setting of the protective frame 2 makes the bottom side of the signal generator body 1 higher than the placement position such as the desktop, avoiding water from penetrating into the interior of the generator body 1, so that the electrical components inside the signal generator body 1 will not be immersed and short-circuited, thereby improving the stability of the signal generator body 1.

[0032] Working principle: When in use, the protective frame 2 is sleeved on both sides of the signal generator body 1, so that the heat dissipation fan 201 is aligned with the vent 212, and then the substrate 203 is attached to the high-temperature component generated when the signal generator body 1 works, and the mounting block 207 is installed on one side of the substrate 203. When the temperature of the high-temperature component inside the signal generator body 1 is too high, the heat will be transferred to the bimetallic strip 206 through the substrate 203. The bimetallic strip 206 will deform and bend due to the high temperature, so that the negative electrode block 208 will be attached to the positive electrode block 209, so that the heat dissipation fan 201 is turned on and energized, so that the heat dissipation fan 201 starts to work, so that the electrical components inside the signal generator body 1 can be cooled, the temperature of the electrical components inside the signal generator body 1 can be reduced, and the stability of the signal generator body 1 can be improved.
