Detailed Description

The present invention is described in further detail below.

As shown in fig. 1, the keyboard convenient to adjust comprises a key 1, a housing upper cover 2, a positioning plate 3, a circuit board 4, a clamping plate 5, a battery 6, a keyboard lower cover 11 and the like.

The utility model discloses change the traditional formula pivot support of burying of keyboard into disconnect-type support, including keyboard body and pipe shape support, keyboard body rear end bottom is equipped with two at least rectangular shape recesses 17 that traverse the keyboard body. The extending direction of each strip-shaped groove 17 is parallel to the length direction of the keyboard body.

As shown in fig. 2, in this embodiment, the elongated grooves 17 include a first groove, a second groove and a third groove, and the first groove, the second groove and the third groove are sequentially arranged from the rear end of the keyboard body to the front end of the keyboard body. When the circular tube-shaped support abuts against the lower ends of the first groove, the second groove and the third groove respectively, the inclination angles theta of the keyboard body are 5 degrees, 6 degrees and 7 degrees respectively.

Specifically, the round tube shaped bracket comprises a round tube core 10, and a soft round tube sleeve 9 is sleeved outside the round tube core 10. The circular sleeve 9 can roll in the elongated groove 17 along the arc of the elongated groove 17. The length of the pipe core 10 and the pipe sleeve 9 is equal to the length of the elongated groove 17.

At ordinary times, the round tube-shaped bracket is placed on the office desktop and embedded in any elongated groove 17 at the bottom of the keyboard. Because the diameter of the circular pipe sleeve 9 is larger than the depth of the strip-shaped groove 17, the circular pipe sleeve 9 and the circular pipe core 10 increase the height of the rear part of the keyboard body, so that the keyboard body is in a forward inclined state.

When the inclination angle of the keyboard needs to be adjusted, a user lightly presses two sides of the keyboard body and moves the keyboard body back and forth by using the palm of the hand with the round tube-shaped support as a fulcrum, so that the round tube sleeve 9 and the round tube core 10 roll on the office desktop together and roll out of the current elongated groove 17, and then continue to roll below the keyboard body and enter the other elongated groove 17. Because at least two strip-shaped grooves 17 are sequentially arranged from the rear end of the keyboard body to the front end of the keyboard body, when the circular tube sleeve 9 is embedded in different strip-shaped grooves 17, the inclination angle of the keyboard body changes. The adjusting mode changes the traditional action that a user lifts the keyboard to search the support and uses fingertips to pull the support out into the action of pushing the keyboard back and forth, improves the fault-tolerant rate of adjusting the support, and increases the interestingness of adjustment. Therefore, the utility model discloses can easily adjust the keyboard inclination, need not to use the nail to scratch out the support in the accommodation process, can not wear and tear or scrape colored nail, specially adapted first personage (especially long nail personage) uses, and user experience is good.

In order to make the adjustment process quiet and noiseless, the circular tube sleeve 9 is made of a silica gel material.

As shown in fig. 1, in order to maintain the stability of the circular tube shaped support during the use of the keyboard, a magnet 7 is arranged in the rear part of the keyboard body, and the covered areas of the first groove, the second groove and the third groove correspond to the magnet 7. Meanwhile, the round tube core 10 is made of metal, so that the round tube core 10 cannot easily roll in the elongated groove 17 due to the magnetic attraction of the magnet 7, and stability is kept.

In this embodiment, two magnets 7 are provided, and are respectively located at the left and right ends of the keyboard body. The magnet 7 is arranged below the clamping plate 5, and electromagnetic shielding coating is additionally arranged on the bottom surface of the clamping plate 5 to reduce the influence of a magnetic field on upper parts.

In order to further increase the stability of the keyboard in use, a plurality of weight parts 8 are arranged in the front part of the keyboard body.

The prior art keyboard key 1 is usually a hard key cap 14, when a user types, the middle part of the key 1 is generally pressed by using a fingertip or a finger belly, at this time, a nail of a nail beautifying person (especially a nail-growing person) touches the surface of the hard key cap 14, noise is easily generated, and nail abrasion is accelerated.

As shown in fig. 4, in this embodiment, the key 1 of the keyboard body is improved and divided into two parts, one part is a hard keycap 14 made of hard plastic, a sinking step is arranged at the rear part of the hard keycap 14, and the hard keycap 14 is in a shape of a thick and flat "L"; the other part is a soft keycap 13 made of soft plastics, the soft keycap is in a shape like a Chinese character 'yi', the soft keycap is connected to the sunken step of the hard keycap 14 through adhesive, and the top end of the front part of the hard keycap 14 is flush with the top end of the soft keycap 13. Hard keycaps 14 and soft keycaps 13 together form a single keycap.

When the keyboard is used, the middle of the hard keycap 14 is pressed by the finger tip and the finger pulp of a user to type, and the longer fingernail falls on the soft keycap 13 at the rear part of the hard keycap 14. The flexibility of soft key cap 13 makes user's nail obtain bearing and protection, reduces the noise that sends when pressing, has slowed down beautiful first wearing and tearing, and specially adapted beautiful first personage (especially long nail personage) uses.

As shown in fig. 3 and 5, in order to enhance the moving performance of the keyboard, in the present embodiment, the keyboard body is provided with a circuit board 4, a battery 6 and a charging port 16, and the circuit board 4 is connected to the charging port 16 and the battery 6, respectively. The battery 6 is used for supplying power, so that the constraint of keyboard connecting wires is reduced. Be equipped with a plurality of bluetooth connector link 12 on the keyboard body, all be equipped with pilot lamp 15 on every bluetooth connector link 12.

When the Bluetooth wireless connection device is used, a user presses any Bluetooth connection key 12 for a long time to enter a pairing mode, and the indicator light 15 begins to flash; when the pairing with the external device is successful, the indicator lamp 15 is turned off after being turned on for a long time. When switching external equipment, click arbitrary bluetooth connection key 12 that has paired, the keyboard will be connected with another external equipment, extinguishes after the pilot lamp 15 is bright for a long time, the automatic disconnection of the external equipment of former connection.

The above embodiments are preferred embodiments of the present invention, but the embodiments of the present invention are not limited to the above embodiments, and any other changes, modifications, substitutions, combinations, and simplifications which do not depart from the spirit and principle of the present invention should be equivalent replacement modes, and all are included in the scope of the present invention.
