DETAILED DESCRIPTION

[0022] The present invention will be further described below in conjunction with specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention but are not intended to limit the present invention.

[0023] Example: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 A keyboard that is easy to install is shown.

[0024] The first embodiment of the utility model refers to Figure 1 and Figure 2 A keyboard that is easy to install includes a first shell 1 and keys 9. The first shell 1 is a box structure with an opening at the bottom. A second shell 2 is arranged at the lower part of the first shell 1. A circuit board 8 is arranged inside the second shell 2. The first shell 1 and the second shell 2 together form a closed shell, providing an installation protection place for the circuit board 8. The keys 9 are evenly arranged on the circuit board 8. The keys 9 include a key shaft and a key cap. The key shafts are respectively installed corresponding to the contacts on the circuit board 8. The key caps are arranged on the upper part of the key shaft. The key caps pass through the avoidance holes 101 opened on the upper part of the first shell 1. As a preferred embodiment, Figure 2 and Figure 3 As shown, the second shell 2 is plugged into the lower opening of the first shell 1, and the second shell 2 is connected to the first shell 1 through a snap-fit ​​mechanism, which includes a spring piece 203, which is respectively tilted in the control port 202 opened on the front and rear sides of the second shell 2, and the outer end of the spring piece 203 is tilted outward, and the spring piece 203 is snap-fitted with the slot 102 opened inside the first shell 1. The second shell 2 is provided with a regulating device for controlling the contraction of the spring piece 203, and the regulating device can control the outer end of the spring piece 203 to contract inward, so that the spring piece 203 is separated from the slot 102, which is convenient for disassembly and maintenance of the keyboard.

[0025] When installing the keyboard, first fix the key shafts of the keys 9 at the corresponding positions of the circuit board 8, fix the circuit board 8 inside the second shell 2, insert the second shell 2 into the lower opening of the first shell 1, and after the upper end of the second shell 2 enters the interior of the first shell 1, the outer end of the spring 203 is inserted into the slot 102 opened inside the first shell 1, and finally the keycap of the key 9 is installed above the key shaft through the avoidance hole 101, so as to achieve quick installation of the keyboard.

[0026] The second embodiment of the utility model refers to Figure 1 and Figure 4 As shown, the regulating device includes a guide rod 3 and a slide rod 4. The guide rod 3 is fixedly arranged between the left and right inner walls of the second shell 2. There are two slide rods 4, which are slidably arranged at the left and right ends of the guide rod 3 respectively. The lower part of the slide rod 4 passes through the slide openings 201 opened on the left and right sides of the second shell 2 respectively, so as to facilitate manual operation of the slide rod 4. Control rods 401 are obliquely arranged at the front and rear ends of the slide rod 4. The outer ends of the control rods 401 are inclined outward in an eight-shaped shape. The control rods 401 are respectively slidably connected with control blocks 204 arranged at the movable ends of the spring pieces 203. Preferably, a spring 5 is provided on the outer sleeve of the guide rod 3. The spring 5 is located between the two slide rods 4. In the absence of external force, the spring 5 can avoid The slide bar 4 automatically moves to improve the stability of the overall structure. Preferably, the regulating device also includes a push block 6, which is respectively arranged at the lower end of the slide bar 4. The outer side surfaces of the push blocks 6 are each provided with stripes 601. The push block 6 provides a manual operation position for the user. The stripes 601 can increase the friction between the push block 6 and the user's hand, thereby facilitating the pushing of the push block 6 to move. Preferably, the second shell 2 is provided with a partition 7, and the circuit board 8 is located above the partition 7. The partition 7 separates the regulating device from the circuit board 8 to ensure that the regulating device and the circuit board 8 do not interfere with each other. A positioning rod 701 is provided on the upper part of the partition 7, and a positioning hole 801 opened on the outer side of the circuit board 8 is plugged into the positioning rod 701.

[0027] When disassembling and repairing the keyboard, the two push blocks 6 are manually pushed closer to each other, and the push blocks 6 drive the slide bar 4 to slide along the guide rod, so that the control rod 401 slides inward along the slide hole inside the control block 204. Since the length of the slide bar 4 is fixed, as the control rod 401 slides in the slide hole inside the control block 204, the control block 204 pulls the spring sheet 203 toward the middle of the second shell 2, so that the outer end of the spring sheet 203 shrinks, the spring sheet 203 disengages from the slot 102, and the second shell 2 is pulled outward to separate the second shell 2 from the first shell 1, thereby realizing the rapid disassembly operation of the keyboard.
