DETAILED DESCRIPTION

[0027] The following will refer to the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] In order to further understand the content of the utility model, the utility model is described in detail with reference to the accompanying drawings.

[0029] Reference Figure 1-6 The utility model discloses a Bluetooth wireless keyboard with calculator function, comprising a base 1, a keyboard body 2 is arranged on the top of the base 1 (the keyboard body 2 is a Bluetooth wireless keyboard in the prior art), rotating ears 4 are rotatably arranged at the front ends of the left and right sides of the keyboard body 2, and the bottoms of the rotating ears 4 are fixed to the base 1, fixed frames 5 are fixed to the left and right sides of the top of the base 1, moving blocks 51 are slidably arranged inside the two fixed frames 5, a lower limb connecting rod 52 is fixed between the two moving blocks 51, fixed ears 57 are fixed to the left and right sides of the rear end of the keyboard body 2, an upper limb connecting rod 58 is fixed between the two fixed ears 57, linkage rods 56 are rotatably arranged at both ends of the upper limb connecting rod 58, and the bottom ends of the linkage rods 56 are rotated on the lower limb connecting rod 52, the tops of the two fixed frames 5 are provided with evenly distributed reserved through holes 53, the tops of the two moving blocks 51 are provided with limiting holes 55, the tops of the two fixed frames 5 are provided with limiting bolts 54, and the limiting bolts 54 are penetrated in the reserved through holes 53 and the limiting holes 55;

[0030] The moving block 51 is moved inside the fixed frame 5, and the lower limb connecting rod 52 can ensure that the two moving blocks 51 can move synchronously. When the moving block 51 moves, the lower limb connecting rod 52 connected thereto moves simultaneously. At the same time, due to the rotation of the linkage rod 56, the linkage rod 56 will change its angle with the upper limb connecting rod 58 and the lower limb connecting rod 52, and the moving block 51 drives the linkage rod 56 to move and rotate. During the process, thrust is generated, and the thrust at this time is transmitted to the upper limb connecting rod 58, so that the keyboard body 2 changes its angle with the rotating ear 4 as the axis point. Therefore, the inclination of the keyboard body 2 can be adjusted according to the use habits and comfort. Compared with the keyboard in the prior art, the adjustment range of the keyboard body 2 of this keyboard body 2 has been greatly improved, and it can be suitable for different people to use. After the adjustment is completed, the limit bolt 54 is passed through the reserved through hole 53 where the moving block 51 stops, and it is inserted into the limit hole 55 above the moving block 51 to complete the limit, so as to avoid the keyboard body 2 from sliding twice during use, which affects the use experience.

[0031] A rubber pad 6 is provided at the front end of the keyboard body 2, and the bottom of the rubber pad 6 is installed on the base 1. The rubber pad 6 can provide buffer protection for the user's joints or forearms to avoid uncomfortable experience. A placement box 7 is passed through and slidably at the front end of the base 1. A reserved opening 8 is provided at the front end of the placement box 7. The placement box 7 is pulled out through the reserved opening 8, and some tools for cleaning the keyboard body 2 can be placed, which is convenient for storage and use. Lower magnetic strips 9 are installed on the left and right sides of the keyboard body 2, and a dust cover 10 is provided on the top of the keyboard body 2. Upper magnetic strips 11 are installed on the left and right sides of the bottom of the dust cover 10, and the upper magnetic strips 11 are magnetically connected to the lower magnetic strips 9; when the keyboard body 2 is used, the dust cover 10 is covered on the top of the keyboard body 2. Due to the upper magnetic strips 11 and the lower magnetic strips 9 on both sides of the dust cover 10 under the action of magnetic attraction, the dust cover 10 better covers the top of the keyboard body 2, avoiding the situation of misalignment and affecting the dustproof effect;

[0032] A display module 3 is arranged at the upper right corner of the keyboard body 2 . A calculator chip is arranged inside the keyboard body 2 . The calculator chip is electrically connected to the Num Look key above the keyboard body 2 , and the calculator chip is also electrically connected to the display module 3 .

[0033] When the user presses the Num Look key, the calculator chip (the calculator chip is the prior art) will be triggered to work, and then the numeric keys on the upper right side of the keyboard body 2 can be used for calculations according to the way of using a calculator. The keyboard body 2 has an integrated chip with calculator functions, which can perform basic mathematical operations, such as addition, subtraction, multiplication, and division, and transmit the results to the display module 3 (the display module 3 is the display screen in the prior art) for display.

[0034] Reference Figure 1 , 7 8. The utility model is a Bluetooth wireless keyboard with calculator function. Shells 12 are provided on the left and right sides of the rear end of the base 1. The two shells 12 are connected to the base 1 by multiple sets of bolts 13. Sliding columns 121 are slidably arranged inside the two shells 12. Fixed columns 122 are fixed to the rear ends of the two sliding columns 121, and the fixed columns 122 are located outside the shell 12. A bearing plate 123 is fixed to the top ends of the two fixed columns 122. The front and rear ends of the two fixed columns 122 are connected to the bearing plate 123 by a support rod 124. A connecting column 125 is fixed at the bottom end between the two fixing columns 122. A fixing plate 126 is fixed at the front end between the two shells 12. Screws 127 are fixed at the middle of the rear end of the fixing plate 126 and the middle of the front end of the connecting column 125. One of the two screws 127 is a positive thread and the other is a negative thread. The outer diameters of the two screws 127 are threadedly connected with sleeves 128.

[0035] When the sleeve 128 is rotated, the sleeve 128 and the screw rod 127 will produce opposite rotation directions under the action of the thread and the positive and negative teeth. Therefore, the rotation of the sleeve 128 increases the distance between the two screw rods 127. At the same time, as the distance between the screw rods 127 gradually increases, the sliding column 121 moves inside the shell 12 to move with the screw rod 127. Therefore, the distance between the bearing plate 123 and the keyboard body 2 can be adjusted according to the usage habits. After the adjustment is completed, the computer is placed on the bearing plate 123 to facilitate the support of the computer and avoid the need to buy a computer stand separately. If the bearing plate 123 is not needed, the bearing plate 123 can be partially separated from the keyboard body 2 by unscrewing the bolt 13 under the action of the thread and removing it.
