Specific embodiments
[0026] The following describes the present utility model in detail with reference to the accompanying drawings and specific embodiments, but it is not a limitation to the present utility model.
[0027] Embodiment: A portable Bluetooth keyboard, as Figures 1 - 4 , Figure 6 , Figure 7 and Figure 9 shown, includes a keyboard body 1, a slider 3, a cover plate 4 and a limiting component. The left parts of the front and rear sides inside the cover plate 4 are symmetrically and rotatably connected with sliders 3. The front and rear sides of the keyboard body 1 are symmetrically provided with chutes 2. The two sliders 3 are respectively slidably connected in the two chutes 2. The cover plate 4 is provided with a limiting component.
[0028] As Figures 1 - 4 , Figure 6 , Figure 7 and Figure 9 shown, the limiting component includes a clamping rod 5 and a return spring 6. The middle part of the right side of the cover plate 4 is slidably connected with the clamping rod 5. A return spring 6 is fixedly connected between the right end of the clamping rod 5 and the right side of the cover plate 4. The return spring 6 is wound around the clamping rod 5. A straight slot 51 is opened in the middle part of the left side of the keyboard body 1. When the right side of the cover plate 4 is attached to the left side of the keyboard body 1, the clamping rod 5 is located at the left end of the straight slot 51. By pushing the clamping rod 5 to the right and inserting it into the straight slot 51, the return spring 6 will be compressed. Then, the clamping rod 5 is rotated by a certain angle so that the clamping rod 5 intersects with the straight slot 51, thereby realizing the limitation of the keyboard body 1 by the clamping rod 5 and completing the stable closing between the cover plate 4 and the keyboard body 1.
[0029] As Figure 3 , Figure 5 , Figure 8 and Figure 11As shown, it further includes a rotating plate 11 and a torsion spring 12. The lower left side inside the cover plate 4 is rotatably connected to a rotating plate 11, and both ends of the rotating plate 11 are respectively connected to the front and rear sides inside the cover plate 4 with torsion springs 12.
[0030] As Figure 6 and Figures 9 - 12 shown, it further includes a placement rack 10 and a clamping assembly. A placement groove 8 is formed in the rear left side of the keyboard body 1. A placement rack 10 is slidably connected inside the placement groove 8. The upper part of the rear side of the placement rack 10 is located above the top of the keyboard body 1, and a clamping assembly is provided inside the placement groove 8.
[0031] As Figure 11 and Figure 12 shown, the clamping assembly includes a clamping block 9 and a compression spring 91. The lower part inside the placement groove 8 is symmetrically and slidably connected to clamping blocks 9 on the left and right. Symmetrically inclined grooves are formed in the lower parts of the sides of the two clamping blocks 9 facing each other. The inclined grooves of the two clamping blocks 9 are respectively in contact and fit with the left and right sides of the placement rack 10. Compression springs 91 are respectively connected between the sides of the two clamping blocks 9 facing away from each other and the left and right sides inside the placement groove 8.
[0032] Initially, the cover plate 4 is located below the keyboard body 1, and the lower part of the keyboard body 1 is embedded inside the cover plate 4. A USB receiver is inserted into the placement groove 8. Under the action of the compression spring 91, the two clamping blocks 9 respectively fit with the left and right sides of the USB receiver, so as to clamp the USB receiver. The front side of the bottom of the placement rack 10 contacts the bottom inside the placement groove 8.
[0033] When taking out the USB receiver, pull the placement rack 10 upward. The placement rack 10 drives the USB receiver to move upward, and the placement rack 10 contacts and squeezes the two clamping blocks 9 through the inclined grooves, driving the two clamping blocks 9 to move toward the side away from the USB receiver, and the compression spring 91 is compressed, so as to release the clamping of the USB receiver, and it can push the USB receiver upward while releasing the limit, facilitating taking out the USB receiver for use.
[0034] When the Bluetooth keyboard is not in use or needs to be carried, push the cover plate 4 to move to the right. The cover plate 4 drives the slider 3 and the rotating plate 11 to move to the right. During the process of the cover plate 4 moving to the right, the rotating plate 11 contacts and moves relative to the keyboard body 1. The keyboard body 1 causes the rotating plate 11 to rotate counterclockwise to open, and the torsion spring 12 is compressed. When the cover plate 4 drives the slider 3 to slide to the right side in the chute 2, rotate the cover plate 4 counterclockwise, and the rotating plate 11 disengages from the keyboard body 1. Under the elastic force of the torsion spring 12, the rotating plate 11 rotates clockwise to reset and contacts the right side of the keyboard body 1. At this time, the cover plate 4 is located above the keyboard body 1, the right side of the cover plate 4 fits with the left side of the keyboard body 1, and the latch 5 is located at the left end of the one-word slot 51. By pushing the latch 5 to the right until the latch 5 is inserted into the one-word slot 51 to the right, the return spring 6 will be compressed. Then rotate the latch 5 by a certain angle so that the latch 5 intersects with the one-word slot 51. The keyboard body 1 is limited by the latch 5, so that the cover plate 4 and the keyboard body 1 are stably closed, realizing the limitation of the cover plate 4 on the keyboard body 1. It can effectively avoid dust and prevent other items from wearing and colliding with the keycaps, which is convenient for carrying and using, ensures the subsequent use effect, improves the safety of use, and extends the service life.
