DETAILED DESCRIPTION

[0024] The technical scheme in the utility model will be described clearly and completely in connection with the drawings in the utility model embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by the ordinary skilled in the art without creative labor belong to the protection scope of the utility model.

[0025] Embodiment: Please refer to Figures 1-6 The utility model provides a kind of technical scheme: a novel taxi printer price calculator, including display screen 1, protective shell 2 and back cover plate 3, further include:

[0026] Bolt 5 is internally arranged in back cover plate 3, and the end of bolt 5 can be arranged sharply;

[0027] Round table column 7 is movably arranged in the interior of protective shell 2 and movably arranged in the end surface of bolt 5;

[0028] Limiting component 6 is arranged in protective shell 2, when back cover plate 3 and bolt 5 are installed on protective shell 2, round table column 7 can be extruded to move, to drive limiting component 6 to clamp back cover plate 3 at protective shell 2.

[0029] Limiting component 6 includes spline shaft 63 movably arranged in the interior of protective shell 2, and multiple sliding grooves 67 are formed in the end surface of round table column 7, spline shaft 63 is movably arranged in the inner wall of corresponding sliding groove 67, and spline shaft 63 can make round table column 7 move freely.

[0030] The side of back cover plate 3 close to protective shell 2 is provided with fixed block 64, L-shaped rod 65 is movably arranged in the interior of fixed block 64, inclined block 66 is arranged on the outer surface of round table column 7, the end surface of L-shaped rod 65 is arranged on the side of inclined block 66, and inclined block 66 can be moved by the movement of round table column 7, so that L-shaped rod 65 is moved by inclined block 66.

[0031] The outer surface of round table column 7 is provided with clamping groove 68, the side of inclined block 66 is provided with connecting groove 69, connecting groove 69 is movably arranged on round table column 7, and inclined block 66 is movably arranged in clamping groove 68, when the part of inclined block 66 separated by connecting groove 69 enters clamping groove 68, it is difficult to take out.

[0032] The outer surface of protective shell 2 is provided with limiting groove 61, the end surface of L-shaped rod 65 away from inclined block 66 is provided with limiting block 62, limiting block 62 is movably arranged on the inner wall of limiting groove 61, and L-shaped rod 65 can drive limiting block 62 to enter limiting groove 61, at this time, back cover plate 3 is difficult to be separated from protective shell 2.

[0033] The inner wall of the protective shell 2 is provided with a baffle 4, the baffle 4 divides the protective shell 2 into two parts, the end surface of the spline shaft 63 is rotatably arranged on the side surface of the baffle 4, and the arrangement of the baffle 4 makes it impossible to enter the protective shell 2 to tamper with data when the part connected with the display screen 1 of the protective shell 2 is pried open.

[0034] Working principle: when using the device, first put the bolt 5 into the inside of the rear cover plate 3, and paste the rear cover plate 3 tightly on the side of the protective shell 2, then twist the bolt 5 to make the bolt 5 extrude the circular truncated cone column 7, the circular truncated cone column 7 will slide on the outer surface of the spline shaft 63, and the inclined block 66 on the outer surface will move, the inclined block 66 will drive the L-shaped rod 65 to move, because the L-shaped rod 65 is limited by the fixed block 64, so the L-shaped rod 65 will drive the limiting block 62 to enter the limiting groove 61, at this time the separated part of the inclined block 66 in the connecting groove 69 enters the clamping groove 68, so it is difficult to open the rear cover plate 3.
