Embodiment Construction

[0017] Figure 1-Figure 4 As a preferred embodiment of the present invention, as shown in the figure, the elastic adjustment device of the pull bar type keyboard key of the present invention includes a bottom plate 1, an adjustment shaft 2, an adjustment wrench 3 and a chuck 4, the bottom plate 1 has a square groove, and the adjustment shaft 2 Placed in the bottom plate 1 groove, the adjustment shaft 2 has a cut surface along the axis; the adjustment wrench 3 is installed at the end of the adjustment shaft 2, and is perpendicular to the axis of the adjustment shaft 2; there are multiple clamps on the chuck 4 for clamping the adjustment wrench slot.

[0018] The cutting surface of the adjusting rotating shaft 2 cuts the adjusting rotating shaft 2 into a semi-cylindrical shape, and the width of the cutting surface is greater than zero and smaller than the diameter of the adjusting rotating shaft 2 .

[0019] In the device, an adjusting wrench 3 is installed at both ends of the ...

Abstract

The invention discloses an elasticity adjusting device for a pull rod type keyboard key. The elasticity adjusting device is characterized by comprising a base plate, an adjusting rotating shaft, an adjusting spanner and a chuck. A square groove is formed in the base plate, and the adjusting rotating shaft is installed in the groove of the base plate. The adjusting rotating shaft is provided with a tangent plane along the axis. The adjusting spanner is installed at the tail end of the adjusting rotating shaft and perpendicular to the axis of the adjusting rotating shaft. The chuck is provided with a plurality of grooves used for clamping the adjusting spanner. The adjusting rotating shaft can rotate freely in the groove of the base plate and will not shake. A pull rod of the key is placed on the adjusting rotating shaft, when the tangent plane of the adjusting rotating shaft and the bottom of the groove of the base plate are coincident, the pull rod of the key can reach the lowest position, and when the tangent plane of the adjusting rotating shaft is perpendicular to the bottom of the groove of the base plate, the pull rod of the key can reach the highest position. The positions which the pull rod of the key can reach can be adjusted in a tiny range through rotation of the adjusting rotating shaft, and therefore elasticity of the key is adjusted.

Description

technical field [0001] The invention belongs to keyboard key technology, in particular to a device capable of adjusting the elasticity of a pull-bar type keyboard key. Background technique [0002] Typewriters and modern stenographic machines or stenographs also use lever-type buttons. The biggest feature of the lever-type buttons is that they feel obvious when pressing the buttons, which is helpful for operators to judge whether their keystrokes are in place when typing quickly. However, the button elasticity of the existing pull-bar type keyboard is uniform, and all operators need to implement the same pressing force to complete the operation. In fact, there are differences in strength between different operators, and everyone's keystroke habits are different. In the case of only one type of button elasticity, the operator can only change himself to fit the keyboard no matter how hard he is or how he is used to it. This often causes people with weak strength to be unable...
