Description

Technical Field

[0001] The present invention relates to the field of mixing consoles, and in particular to a mixing console and a system thereof with a protection function for adjustment keys. Background Art

[0002] A mixing console, also known as a mixing control console, amplifies, mixes, distributes, modifies the sound quality, and processes the sound effects of multiple input signals, and then outputs through the bus. The mixing console is an important device for broadcasting and recording programs in modern radio broadcasting, stage sound reinforcement, audio program production and other systems;

[0003] Patent: CN219068318U discloses a live mixing console. The live mixing console includes: an operation panel disposed obliquely; and a support plate stably disposed at one end of the operation panel for stabilizing the operation panel; the support plate and the operation panel are connected to form a V-shaped frame for supporting the live mixing console. A plurality of knobs are provided on the operation panel for tuning the audio. A non-slip pad assembly is provided at the bottom of the V-shaped frame. One pad assembly is installed on the support plate, and the other is installed on the operation panel. For this live mixing console, the operation panel and the support plate form a V-shaped frame, so that the operation panel is disposed obliquely, and the buttons and knobs face the user, which is more convenient to operate. Moreover, the V-shaped structure is more conducive to the stable placement of the live mixing console. A non-slip pad assembly is provided below the mixing console, with a simple structure and convenient use. The mixing console has various functions, convenient tuning operation, stable placement, and good stability of the tuning operation;

[0004] The mixing console in the above technology cannot be adjusted to different heights according to the user's habits, and simply setting a non-slip pad assembly below the mixing console for anti-slip cannot ensure the stable placement of the device. When a sound engineer uses the mixing console, it is easy to cause the mixing console to displace, resulting in inconvenient use. Moreover, the above technology cannot effectively clean the dust on the adjustment keys, and thus cannot achieve a protection effect, so improvement is needed. For this reason, we propose a mixing console and a system thereof with a protection function for adjustment keys. Summary of the Invention

[0024] Beneficial effects: Control the rotation of the bidirectional screw, the two moving strips move away from each other, the liquid inside the first hollow tube is squeezed into the second hollow tube, pushing the piston push rod two downward, and then pushing the wedge-shaped extrusion block backward. By embedding the wedge-shaped extrusion block under the lifting plate, the lifting plate is lifted. At this time, multiple piston blocks will rise along the adsorption holes, and the adsorption holes inhale air, so that it can be adsorbed on a smooth placement surface to ensure the stable placement of the device.

[0025] Continue to rotate the bidirectional screw to control the two moving strips to continue to move away from each other. At this time, since the piston push rod one is completely retracted, under the rotational connection of the rotating connector one and the rotating connector two, the piston push rod one will rotate and tilt along the center of the connection axis of the rotating connector one and the rotating connector two, thereby pushing the mixing console body to rise. This method enables the user to adjust the height of the mixing console body according to needs, facilitating the use of users with different habits.

[0026] Hold the suction head, pull out the second branch pipe, then start the air pump to pump air, and pump air at the control keys on the mixing console body with the suction head, which can extract dust and achieve a dust-proof protection effect; the sucked dust will be filtered by the filter mesh cylinder and stored in the filter cavity. Release the suction head, and under the pulling and resetting of the torsion spring, the second branch pipe will be rewound again, which is convenient for storage. By opening the sealing cover, it is convenient to clean the dust.

[0027] When sucking dust, the motor can be started at the same time. Through the meshing transmission of the first bevel gear, the second bevel gear and the third bevel gear, the circular tube and the rotating rod will drive the brush and the filter mesh cylinder to rotate relative to each other. On the one hand, the filter mesh cylinder rotates during the filtering process to avoid the problem that the first branch pipe enters dust and is only filtered on one side of the filter mesh cylinder, resulting in poor filtering effect and easy blockage. At the same time, the brush can clean the inner side of the filter mesh cylinder to further avoid blockage, and the cleaning and filtering effect is better. Description of the Drawings

[0044] A hollow tube two 10 is fixedly connected to the front surface inside the storage groove 4, a piston push rod two 11 is slidably connected inside the hollow tube two 10, the bottom end of the piston push rod two 11 penetrates below the hollow tube two 10 and is rotatably connected through a rotating shaft to a traction rod 12, the bottom end of the traction rod 12 is rotatably connected through a rotating rod to a longitudinal push block 13, and a wedge-shaped extrusion block 14 is fixedly connected to the rear end of the longitudinal push block 13;

[0045] A ventilation pipe 15 is fixedly connected and communicated between the hollow tube one 9 and the hollow tube two 10;

[0047] In the normal state, the adsorption bottom plate 201 fits against the bottom of the mixing console body 1, which is convenient for taking and placing at this time;

[0048] There is liquid for extrusion between the hollow tube one 9 and the hollow tube two 10 to ensure the transmission efficiency;

[0049] When in use, by controlling the rotation of the bidirectional screw 5, the two moving bars 6 are controlled to move away from each other. At this time, the piston push rod one 8 will contract towards the inside of the hollow tube one 9, and the liquid inside the hollow tube one 9 will be extruded into the hollow tube two 10, pushing the piston push rod two 11 to descend. Then, under the push of the traction rod 12 and the longitudinal push block 13, the wedge-shaped extrusion block 14 will be pushed to move backward, so that the wedge-shaped extrusion block 14 is embedded under the lifting plate 206, causing the lifting plate 206 to rise.

The rear end of the rotating rod 307 penetrates into the interior of the filter cavity 303, and a plurality of air inlet holes 308 are opened;

[0058] A air pump 309 is fixedly connected to the front surface inside the transmission cavity 302 to the right of the hollow cylinder one 306. The input end of the air pump 309 is communicated with the inside of the hollow cylinder one 306, and the output end of the air pump 309 penetrates to the right of the installation box 301;

[0059] The rear surface inside the transmission cavity 302, and outside the rotating rod 307 is rotationally connected to a circular tube 310 through a rotating shaft. The front end of the circular tube 310, and outside the rotating rod 307 is fixedly connected to a second bevel gear 311. The outer wall of the rotating rod 307 is fixedly connected to a third bevel gear 312 in front of the second bevel gear 311. The first bevel gear 305 is meshed with both the second bevel gear 311 and the third bevel gear 312;

[0060] The outer wall of the rotating rod 307 is fixedly connected to a filter screen cylinder 313 inside the filter cavity 303. The outer wall of the rotating rod 307 is fixedly connected to two brush hairs 314 on the outer side wall of the filter screen cylinder 313.

[0062] When the device is in use, the suction head 321 can be held by hand, the second branch pipe 320 can be pulled out, and then the air pump 309 is started. Under the combined connection of the first hollow cylinder 306, the rotating rod 307, the air inlet hole 308, the first branch pipe 318, the shaft pipe 319 and the second hollow cylinder 317, air is pumped.
