DETAILED DESCRIPTION

[0024] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0025] like Figure 1-Figure 4 As shown, the embodiment of the utility model proposes a portable calculator, including a calculator body 1, a screen saver storage assembly and a support assembly: the calculator body 1 is provided with a display screen 2 and an operation keyboard 3, the operation keyboard 3 includes a function area 19 with shortcut keys commonly used by financial and tax staff integrated; the screen saver storage assembly includes two sliding grooves 4 opened on the two side walls of the calculator body 1, each sliding groove 4 is slidably connected with a limited sliding shaft 5, the sliding groove 4 and the limited sliding shaft 5 are both convex in cross section, and the inner surface of the sliding groove 4 and the outer surface of the limited sliding shaft 5 are coated with grease, the two limited sliding shafts 5 are rotatably connected with a transfer rod 6, the ends of the two transfer rods 6 are fixedly connected with a protective plate 7, the inner surface of the protective plate 7 is provided with a soft cotton sheet, and the protective plate 7 is provided with a paddle 16;

[0026] The protective plate 7 is driven to move by toggling the paddle 16. During this process, the limit sliding shaft 5 slowly slides in the sliding groove 4 and stops when the protective plate 7 is located directly above the display screen 2. At this time, the display screen 2 can be fully protected by the protective plate 7 to avoid wear and tear on the display screen and ensure the display effect of the display screen. When the calculator body 1 is in use, the protective plate 7 can also be driven to move by toggling the paddle 16 so that the protective plate 7 moves to the top position of the calculator body 1, and then the protective plate 7 is toggled so that the protective plate 7 rotates 180 degrees and continues to move. The protective plate 7 stops when it is located directly below the display screen 2 on the rear side of the calculator body 1, thereby avoiding the protective plate 7 from occupying additional space, which is conducive to the storage of the calculator screen saver and the portable use of the calculator.

[0027] like Figure 1-Figure 4As shown, a transfer block 13 is rotatably connected to the limit sliding shaft 5 through a small bearing, a fixing plate 14 is fixedly connected to the side wall of the calculator body 1, and a tension spring 15 is fixedly connected between the fixing plate 14 and the transfer block 13, and the tension spring 15 is made of polypropylene plastic spring;

[0028] When the protective plate 7 is driven to move to protect the display screen 2, the tension spring 15 can pull the adapter block 13 and the limiting sliding shaft 5 through its own elastic force, thereby assisting in driving the protective plate 7 to move directly above the display screen 2. When the protective plate 7 is driven to move to store the protective plate 7, the tension spring 15 can also automatically pull the protective plate 7 to move, thereby realizing automatic resetting of the protective plate 7 and improving the portability of the calculator.

[0029] like Figure 1 and Figure 3 As shown, the support assembly includes a first placement groove 8 provided on the calculator body 1, a rotating shaft 9 is rotatably connected in the first placement groove 8 through a torsion spring, a support plate 10 is fixedly connected to the rotating shaft 9, a paddle 16 is provided on the support plate 10, a support column 17 is fixedly connected to the support plate 10, and an anti-slip coating is provided on the outer surface of the support column 17, and two second placement grooves 11 are provided on the calculator body 1, a support rod 12 is rotatably connected in each second placement groove 11 through a torsion spring, a silicone ball 18 is fixedly connected to the end of the support rod 12, and paddles 16 are provided on the two support rods 12;

[0030] By sequentially toggling the paddles 16 on the support plate 10 and the two support rods 12, the support plate 10 and the two support rods 12 are driven to rotate a certain angle, so that the support plate 10 is disengaged from the first placement groove 8 and the support rod 12 is disengaged from the second placement groove 11. It should be noted that the rotation angles of the support plate 10 and the two support rods 12 are both greater than 90 degrees. The support column 17 on the support plate 10 and the silicone support balls 18 on the two support rods 12 are used as support points, so that the calculator body 1 can be tilted and placed, thereby adapting to the staff's working line of sight and facilitating the staff to operate and view the calculator.

[0031] like Figure 1 As shown, the operation keyboard 3 is mainly composed of two upper and lower partitions. The upper operation keyboard partition, namely the function area 19, is integrated with shortcut function keys commonly used in financial and tax work, and the lower operation keyboard partition is the commonly used numeric keys and operation symbol keys. By integrating the shortcut function keys frequently used in financial and tax work into the function area 19 of the operation keyboard 3, it is convenient for staff to view and operate the calculations of economic transactions.

[0032] The detailed working process of the utility model is as follows:

[0033] 1. When the calculator body 1 is not in use, the protective plate 7 can be driven to move by toggling the paddle 16. During this process, the limit sliding shaft 5 slowly slides in the sliding groove 4 and stops when the protective plate 7 is located directly above the display screen 2. At this time, the display screen 2 can be fully protected by the protective plate 7 to avoid wear and tear on the display and ensure the display effect of the display screen. When the calculator body 1 is in use, the protective plate 7 can also be driven to move by toggling the paddle 16, so that the protective plate 7 moves to the top position of the calculator body 1, and then the protective plate 7 is toggled to rotate 180 degrees and continue to move. The protective plate 7 stops when it is located directly below the display screen 2 on the rear side of the calculator body 1, thereby avoiding the protective plate 7 from occupying additional space, which is conducive to the storage of the calculator screen saver and the portable use of the calculator;

[0034] 2. When the protective plate 7 is driven to move to protect the display screen 2, the tension spring 15 can pull the adapter block 13 and the limit sliding shaft 5 by its own elastic force, thereby assisting in driving the protective plate 7 to move to just above the display screen 2. When the protective plate 7 is driven to move to store the protective plate 7, the tension spring 15 can also automatically pull the protective plate 7 to move, thereby realizing the automatic reset of the protective plate 7, thereby improving the portability of the calculator;

[0035] 3. When the calculator is in use on a desktop, the support plate 10 and the two support rods 12 can be driven to rotate a certain angle by sequentially toggling the paddles 16 on the support plate 10 and the two support rods 12, so that the support plate 10 is disengaged from the first placement slot 8 and the support rods 12 are disengaged from the second placement slot 11. It should be noted that the rotation angles of the support plate 10 and the two support rods 12 are both greater than 90 degrees. The support column 17 on the support plate 10 and the silicone support balls 18 on the two support rods 12 are used as support points, so that the calculator body 1 can be tilted and placed, thereby adapting to the staff's working line of sight and facilitating the staff to operate and view the calculator.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
