Description

Technical Field

[0001] This utility model relates to the field of keyboard technology, specifically to a foldable keyboard. Background Technology

[0002] The keyboard is the most frequently used and primary input device on a computer. It allows users to input English letters, numbers, punctuation marks, and other symbols, thus issuing commands and inputting data. Therefore, common keyboards typically include letter keys, number keys, and a touchpad. However, most keyboards on the market today are one-piece designs with limited functionality, failing to meet the evolving needs of consumers.

[0003] As shown in the announcement number CN 212032124 U, a convenient keyboard includes a main keyboard and a numeric keypad that can be used as an independent calculator. The numeric keypad has a spring pin contact on its left side, and the main keyboard has a connector on its right side near the editing keyboard area. The connector has a copper conductor for assembling with the spring pin contact. This device does not have a convenient elastic fixing method and cannot achieve the stability of the keyboard after folding by simply pressing it down by the operator. Accidental unfolding may occur. At the same time, after fixing, there is no guarantee that there will be a certain gap between the first folding plate and the second folding plate. Under long-term pressure, the keys may wear against each other. There is also no retractable and retractable movable block to ensure the overall aesthetics of the device. Utility Model Content

[0004] The purpose of this invention is to provide an easily foldable keyboard to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A foldable keyboard includes a first folding plate. A telescopic locking mechanism is fixedly provided on one side of the first folding plate. The telescopic locking mechanism includes a telescopic groove, a movable block, a threaded hole, and a fixing screw. The telescopic groove is provided on one side of the first folding plate. The movable block is movably provided inside the telescopic groove. Several threaded holes are provided on both sides of the movable block. A fixing screw is movably provided on the outer side of the first folding plate. One end of the fixing screw is movably connected to the threaded hole.

[0007] The movable block also has elastic fixing mechanisms on both sides. The elastic fixing mechanism includes a movable groove, a telescopic spring, a movable plate, a pressing post, and a locking post. Movable grooves are opened on both sides inside the movable block. Several telescopic springs are fixedly installed on one side of the movable groove. A movable plate is fixedly installed on the other end of the telescopic spring. A pressing post is fixedly installed on the side of the movable plate away from the telescopic spring. A locking post is fixedly installed on the side of the movable plate away from the pressing post.

[0008] Preferably, a movable column is fixedly provided on one side of the first folding plate, and a second folding plate is movably provided on the side of the movable column away from the first folding plate. The first folding plate and the second folding plate can be folded together through the movable column, which is convenient for carrying.

[0009] Preferably, a number of buttons are fixedly provided on one side of the first folding plate and the second folding plate, and the buttons are configured to implement corresponding commands.

[0010] Preferably, the first folding plate and the second folding plate are movably provided with a support block at the end away from the case. The movably provided support block can slightly lift the keyboard, and the user can adjust the height as needed.

[0011] Preferably, the second folding plate has a fitting groove on the side away from the movable column. The fitting groove is movably connected to the movable block. A slot is provided at the bottom of the fitting groove. The slot is movably connected to the locking column. After folding, the movable block is movably connected to the fitting groove, and the slot is elastically connected to the locking column, which facilitates the improvement of the stability of the device after folding.

[0012] Preferably, a plurality of limiting rods are fixedly provided inside the movable block, and a plurality of limiting grooves are started from one side inside the movable plate. The limiting rods and limiting grooves are movably connected. The setting of the limiting rods and limiting grooves prevents the internal telescopic spring of the movable block from shifting when the movable column is pressed, and ensures the stable state when elastically fixed.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. A foldable keyboard, wherein when the keyboard needs to be folded, the first folding plate can be rotated to the top of the second folding plate, the movable block is inserted into the engaging groove, and by pressing the pressing post, the movable plate is pressed in the same direction to compress the telescopic spring, causing it to elastically deform. Under the elastic buffering effect, the engaging post at the other end of the movable plate can also elastically extend and retract, and finally be inserted into the slot for fixed position. When it needs to be unfolded for use, the same method is used to press the engaging post out of the slot. At this time, the fixing screw is removed, the movable block is pressed into the telescopic groove, and then the fixing screw is rotated to insert one end into the threaded hole for fixed position, ensuring that the top of the movable block does not protrude from the surface of the first folding plate.

[0015] 2. This easy-to-fold keyboard has a convenient and flexible fixing method. The keyboard can be folded and stabilized by simple pressing by the staff, avoiding accidental unfolding. At the same time, after fixing, a certain gap is maintained between the first folding plate and the second folding plate to prevent the keys from being squeezed after folding, thus avoiding wear. The retractable and hidden movable block also ensures the overall aesthetics of the device. Attached Figure Description
