Description

Technical Field

[0001] The utility model belongs to the technical field of satellite axis balancing rods for keyboards, in particular to a silent satellite axis balancing rod. Background Art

[0002] The keyboard is the most commonly used and most important input device. Through the keyboard, English letters, numbers, punctuation marks, etc. can be entered into the computer, thereby issuing commands to the computer and inputting data, etc. The long keys of the mechanical keyboard require auxiliary structures. Because the keys are too long, one axis cannot take care of them all, so the balance bar appears. The balance bar is to balance the keys and is an auxiliary structure. In the traditional structure, the balance bar includes a cross bar and two sliding bars. Since the balance bar is made of metal, the keyboard base is also made of metal, which will cause abnormal noise during the impact.

[0003] At the same time, the application number is 202222891792.9, a longer balance bar for keys and a keyboard, the longer balance bar for keys includes two key shafts symmetrically arranged on the mechanical main shaft, the two key shafts are connected by a balance bar, and the balance bar can be linked to achieve synchronous action, the balance bar includes a metal connecting rod and a metal plug rod arranged at both ends of the metal connecting rod, the metal plug rod is arranged perpendicular to the metal connecting rod, the outer wall surface of the metal plug rod is surrounded and wrapped with a soft rubber sleeve, and the soft rubber sleeve is movably connected to the inner wall of the key shaft. The utility model of a keyboard satellite shaft and keyboard can effectively improve the noise when the balance bar and the shaft body collide with each other, and the soft rubber sleeve can effectively prevent the noise generated by the balance bar hitting the inner wall of the key shaft, thereby improving the mute effect, enhancing the practicality during use, and improving the user experience of the mechanical keyboard.

[0004] However, in the implementation of the relevant technology, the following problems were found: a relatively long balance bar for keys and keys were found to collide with the balance bar and the pressing block as well as with the main board during use, resulting in unsatisfactory noise reduction effect of the keyboard, affecting the user experience.

[0005] To this end, we proposed a silent satellite axis balance bar. Utility Model Content

[0006] In order to solve the problems raised in the above-mentioned background technology, the utility model provides a silent satellite axis balance bar, which has the advantage of ideal noise reduction effect of the keyboard during use. No collision will occur between the balance bar and the pressing block, and between the balance bar and the mainboard, thereby achieving the purpose of silent operation and improving the user experience.

[0007] To achieve the above object, the present utility model provides the following technical solution: A silent satellite shaft balance rod, including a support base, a first chute is opened at the top end of the support base, a pressing block is reciprocally slidably arranged on the inner wall of the first chute, a bevel groove is opened at the outer side of the lower part of the pressing block, an oil storage groove is opened inside the pressing block, an oil dripping hole is opened at the bottom end of the inner wall of the oil storage groove, and the oil dripping hole is connected through the top end of the bevel groove.

[0008] Preferably, a third chute is opened at the outer side of the support base, a second guide rail is reciprocally slidably arranged inside the third chute, and a rubber pad is fixedly arranged on the outer side of the second guide rail.

[0009] Preferably, a second chute is opened at the inner wall of the first chute, a first guide rail is reciprocally slidably arranged inside the second chute, and the outer side of the first guide rail is fixedly connected with the outer side of the pressing block.

[0014] Preferably, a second soundproof pad is fixedly arranged at the bottom end of the pressing block.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] 1. By setting the first soundproof pad and the second soundproof pad, when the keycap moves downward, it drives the pressing block to move downward inside the first chute opened at the top end of the support base. The downward movement of the pressing block drives the first guide rail to slide downward inside the second chute. The downward movement of the pressing block drives the balance rod body to rotate downward. The balance rod body rotates inside the rubber pad. The bevel groove squeezes the balance rod body. The first soundproof pad is attached to the top end of the balance rod body. The second soundproof pad at the bottom end of the pressing block is attached to the keyboard main board. Thus, it is found that the noise reduction effect of the keyboard is ideal during use, and no collision occurs between the balance rod and the pressing block, as well as between the balance rod and the main board, thereby achieving the purpose of silencing and improving the user experience.

[0017] 2. By providing an oil dripping hole in the present utility model, the cross sealing bolt at the top of the pressing block is removed, and lubricating oil is injected into the interior of the oil storage tank through a syringe via the oil filling port. After the injection is completed, the cross sealing bolt is tightened. The downward movement of the pressing block drives the lubricating oil to drip onto the outer side of the balance rod body through the oil dripping hole, lubricating the balance rod body, improving the lubrication degree inside the satellite axis balance rod, and enhancing the comfort of the keyboard for consumers when using the keyboard.

When the pressing block 3 moves downward, it drives the first guide rail 5 to slide downward inside the second sliding groove 4. When the pressing block 3 moves downward, it drives the balance rod body 16 to rotate downward. The balance rod body 16 rotates inside the rubber pad 15, and the inclined surface groove 6 squeezes the balance rod body 16. The first soundproof pad 7 fits with the top end of the balance rod body 16, thereby achieving the purpose of sound insulation for the balance rod body 16. When the pressing block 3 moves downward, it drives the lubricating oil to drip onto the outside of the balance rod body 16 through the oil dripping hole 9 to lubricate the balance rod body 16. The second soundproof pad 12 at the bottom end of the pressing block 3 fits with the keyboard main board, thereby achieving the purpose of sound insulation for the satellite axis.
