Description

Technical Field

[0001] The utility model relates to the technical field of signal source switchers, in particular to a high-performance signal source switcher. Background Art

[0002] A signal switcher is also called a signal selector. The main function of a signal converter is to convert one signal into another so as to transmit information between different systems. It can convert analog signals into digital signals, or digital signals into analog signals, and select any one of the multiple input signals to output to the display device. The switcher supports fast and high-definition signal switching, and can switch signals from different input sources in real time and display them on a large screen, ensuring smooth and clear picture transmission. Current signal source switchers are inconvenient to disassemble and repair, and the signal source switcher does not have a drop-proof structure, and is easily damaged after falling, thus affecting normal use. In view of this, in-depth research was conducted on the above-mentioned issues, resulting in this case. Utility Model Content

[0021] The inner wall of the locking rod 2 is provided with an internal thread, and a threaded connection structure is formed between the locking rod 2 and the threaded rod 3;

[0022] A knob 14 is installed at the top of the inspection cover 8, and a driving gear 5 is installed below the knob 14, and driven gears 4 are meshed and installed on both sides of the driving gear 5;

[0023] The outer wall of the other end of the threaded rod 3 is installed with a first bevel gear 6, and the lower part of the driven gear 4 is connected with a second bevel gear 7, and a meshing transmission structure is formed between the second bevel gear 7 and the first bevel gear 6;

[0024] A second damper 21 is installed on the inner wall above the inspection cover 8, and a second buffer spring 22 is installed on the outer wall of the second damper 21. One end of the second buffer spring 22 is connected to a clamping rod 20. The outer wall of the knob 14 is provided with a clamping groove 19 that matches the clamping rod 20.

[0025] Specifically, Figure 1 , Figure 2 and Figure 4 As shown, when this structure is used, the driving gear 5 is rotated by rotating the knob 14, and the driving gear 5 is meshed with the driven gear 4, so that the driven gear 4 drives the second bevel gear 7 to rotate at the same time, and the second bevel gear 7 is meshed with the first bevel gear 6, so that the threaded rod 3 is rotated at the same time, and the locking rod 2 is threadedly matched with the threaded rod 3 to move the locking rod 2 to the side away from the locking groove 9, so that the inspection cover 8 can be disassembled, and then the switch body 10 can be inspected.

[0026] Embodiment 2: The inner wall of the rubber buffer block 12 is evenly installed with the first damper 17, and the outer wall of one end of the first damper 17 is evenly installed with the first buffer spring 15;

[0027] The inner wall of the rubber buffer block 12 is evenly installed with a first magnetic block 16, and the outer wall of the inspection cover 8 and the switch body 10 are both installed with a second magnetic block 18 that matches the first magnetic block 16;

[0028] Specifically, Figure 1 , Figure 2 and Figure 3 As shown, when this structure is used, when the switch body 10 accidentally falls, the rubber buffer block 12 contacts the ground, and the impact force hits the rubber buffer block 12. Through the elasticity of the rubber buffer block 12, a certain buffering effect is achieved, and then the first damper 17 and the first buffer spring 15 are squeezed and deformed to further achieve the buffering effect. At the same time, the repulsive force formed by the first magnetic block 16 and the second magnetic block 18 having the same magnetic pole on one side relative to the other also has a buffering effect, and the anti-fall effect of the switch body 10 is achieved through multiple rubber buffer blocks 12.

[0029] Working principle: When using the device, first connect different signal source interfaces to the VGA interface 1, the HDMI interface 13 and the wired signal interface 11 respectively, and open the inspection cover 8 to inspect the switch body 10;

[0030] The first step to implement the innovation point:

[0031] Step 1: Move the card rod 20 away from the card slot 19, rotate the knob 14 to rotate the driving gear 5, and the driving gear 5 is meshed with the driven gear 4, so that the driven gear 4 drives the second bevel gear 7 to rotate at the same time, and the second bevel gear 7 is meshed with the first bevel gear 6 to rotate the threaded rod 3 at the same time, and the locking rod 2 is threadedly matched with the threaded rod 3 to move the locking rod 2 to the side away from the locking slot 9, and then remove the inspection cover 8;

[0032] Step 2: After the position of the knob 14 is fixed, the clamping rod 20 is loosened, and the second damper 21 and the second buffer spring 22 are reset to lock the clamping rod 20 into the clamping slot 19.

[0033] The second innovation point implementation steps:

[0034] Step 1: When the switch body 10 accidentally falls, the rubber buffer block 12 contacts the ground, and the impact force hits the rubber buffer block 12. Through the elasticity of the rubber buffer block 12, a certain buffering effect is achieved;

[0035] Step 2: The first damper 17 and the first buffer spring 15 are squeezed and deformed to further achieve the buffering effect. At the same time, the first magnetic block 16 and the second magnetic block 18 have the same magnetic poles on one side, so the repulsive force formed also has a buffering effect. The switch body 10 and the inspection cover 8 are protected from collision by multiple rubber buffer blocks 12.
