Description

Technical Field

[0001] The utility model relates to the technical field of keyboard satellite axes, in particular to an ultra-dwarf satellite axis of a keyboard. Background Art

[0002] The satellite axis is used to support the structure of large keys (2x and above) so that one side will not tilt up when the large keys are pressed. The two ends of the satellite axis are shaped like axes, and the middle is connected by a balance bar. However, it is different from the usual axis because it does not control the on-off. The satellite axis in the keyboard refers to adding two axes on both sides of the large key axis of the keyboard to ensure consistency even when pressing both sides of the large key.

[0003] The traditional satellite axis has a relatively high axis height, and a relatively high groove protrudes from the top of the axis for the axis core to move up and down, ensuring that the axis core has sufficient distance to reset, providing a stable connection and ensuring the consistency of the keys. If the groove protruding from the top of the axis becomes shorter, the stability of the axis core connection will be reduced, affecting the quality of the keyboard product and being inconvenient for users to use.

[0017] like Figure 1-3As shown, an ultra-dwarf satellite axis of a keyboard comprises an ultra-dwarf satellite axis body 1 and an axis core 2, wherein the ultra-dwarf satellite axis body 1 is provided with a mounting groove 3 for mounting the axis core 2, and the axis core 2 is raised and lowered in the mounting groove 3, and hooks 4 protrude from both sides of the axis core 2, and inner side walls of the mounting groove 3 are provided with limit slots 5 for one-to-one locking and limiting cooperation with the hooks 4, and the limit slots 5 have an L-shaped gap for the lifting and lowering activities of the hooks 4, and the top of the axis core 2 is provided with a key cap socket 7 for plugging and cooperating with the key caps of the keyboard.

[0018] The ultra-dwarf satellite axis of the keyboard adopts an ultra-dwarf satellite axis body 1 and an axis core 2. The ultra-dwarf satellite axis body 1 is provided with an installation groove 3 for installing the axis core 2. The axis core 2 is raised and lowered in the installation groove 3. Hooks 4 protrude from both sides of the axis core 2. The inner side walls of the installation groove 3 are provided with limiting grooves 5 for one-to-one locking and limiting cooperation with the hooks 4. The limiting grooves 5 have an L-shaped gap for the lifting and lowering activities of the hooks 4 to ensure that the axis core 2 can be lifted and lowered in the installation groove 3 of the ultra-dwarf satellite axis body 1. At the same time, the limiting grooves 5 and the hooks 4 are limited to prevent the axis core 2 from exceeding the ultra-dwarf satellite axis body 1 and detaching, thereby improving the connection stability of the axis core 2. Moreover, compared with the traditional cross-shaped axis core 2, the top of the axis core 2 of the utility model is provided with a key cap socket 7 for the insertion and cooperation of the key caps of the keyboard, thereby further reducing the overall thickness of the ultra-dwarf satellite axis.

[0019] Furthermore, one end of the ultra-dwarf satellite axis body 1 is provided with a balance bar through hole 8 connected to the mounting groove 3, and one end of the axis core 2 is provided with a balance bar clamping hole 9 connected to the balance bar through hole 8, and the balance bar clamping hole 9 passes through the other end of the axis core 2; a plurality of light-transmitting holes 10 are also provided on the top of the axis core 2. It can also ensure that the traditional satellite axis balance bar passes through the balance bar through hole 8 and the balance bar clamping hole 9 is used in conjunction with the axis core 2; in addition, the balance bar clamping hole 9 passes through the other end of the axis core 2, and a plurality of light-transmitting holes 10 are also provided on the top of the axis core 2, so that the light source of the mechanical keyboard is emitted through the light-transmitting hole 10, which is conducive to maintaining a good light effect on the basis of reducing the luminous power. Furthermore, the plurality of light-transmitting holes 10 are evenly distributed.

[0020] Furthermore, a balance pole connecting hook 11 is extended from one end of the ultra-dwarf satellite shaft body 1. The balance pole connecting hook 11 is provided so as to be used in conjunction with a conventional satellite shaft balance pole.

[0021] Furthermore, a keyboard connecting hook 12 is protruded from the other end of the ultra-dwarf satellite shaft body 1. The keyboard connecting hook 12 is provided so as to be engaged with the keyboard.

[0022] Furthermore, an installation guide strip 13 is protruded from the outer side wall of the ultra-dwarf satellite shaft body 1 so as to cooperate with the keyboard and facilitate the installation and introduction of the ultra-dwarf satellite shaft body 1.

[0023] Furthermore, limiting protrusions 14 protrude from the four corners of the mounting groove 3, and the limiting protrusions 14 cooperate with the corners of the mounting groove 3 to form limiting accommodating grooves 6. The ultra-dwarf satellite axis also includes a ball (not shown in the figure) accommodated in the limiting accommodating groove 6. The ultra-dwarf satellite axis body 1 is slidably connected to the shaft core 2 through the ball, so as to reduce abnormal noise due to friction between the ultra-dwarf satellite axis body 1 and the shaft core 2, and avoid friction and wear to reduce the service life.

[0024] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present invention is within the protection scope of the present invention.
