Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mechanical keyboards, in particular to a multi-section foldable space bar cap bracket. Background Art
[0002] The space bar is a key on a computer keyboard, usually located at the bottom of the keyboard. It is a long strip-shaped key. The main function of the space bar is to enter spaces. That is, when entering text, pressing the space bar can insert an invisible space character and move the cursor to the right.
[0003] The space bar keycap is usually made of plastic or metal and is one of the keycaps on the keyboard that is most easily worn. Since the space bar is the longest key on the keyboard, its keycap is also relatively large and needs to withstand greater pressure and friction. If the space bar keycap is severely worn or damaged, it will affect normal use, so it needs to be replaced in time. The method of replacing the space bar keycap is usually to remove the old keycap and then install the new keycap.
[0004] However, the existing space bar caps are rather special and have different sizes. When replacing them, it is necessary to find a keycap that matches the original keyboard. Mistakes are easy to occur during the search, resulting in the found space bar cap being unable to be replaced. The space bar cap may be too long or too small and cannot be adjusted, so it can only be found again, and the scope of use is small. For this reason, we propose a multi-section folding space bar cap bracket. Utility Model Content

[0015] Compared with the prior art, the utility model provides a multi-section foldable space bar cap bracket, which has the following beneficial effects:
[0016] 1. The multi-section foldable space bar cap bracket adopts a multi-spaced shell on the surface for active connection. The shell is centered on the first shell and gradually expands outward. The size of each shell is gradually reduced, making it more convenient to push the shell. In addition, a through hole is provided on the surface of each shell, and the position and size of these through holes are the same, and a movable pin is installed inside each through hole. When the length needs to be adjusted, take out the movable pin and directly push the shell inward. When the required length is reached, the movable pin is inserted into the through hole to fix the length of the space bar cap, which is easy to use.
[0017] 2. The multi-section folding space bar cap bracket has the second connecting column at the bottom installed inside the slot to support the entire bracket. A spring is added under the center block. Pressing the keycap squeezes the spring. When released, the spring rebounds to restore the space bar. A limit block is installed to limit the range of motion of the center column to a certain range. BRIEF DESCRIPTION OF THE DRAWINGS
