Description

Technical Field

[0001] The utility model relates to the technical field of bill calculation boards, in particular to a bill calculation board that is convenient for clamping. Background Art

[0002] The calculation board is an auxiliary device that facilitates users to perform superimposed calculations on bill amounts, and is used to facilitate users' calculations. Current bill calculation boards are mostly composed of a board body and a ticket clip. The ticket clip is set on the upper front part of the board body, and the bill is clamped by the ticket clip. After the calculation of one bill is completed, the bill is turned over and the data of the next bill is calculated. However, the bill is easy to fall back again after being turned over, which interferes with the calculation and is not convenient to use. At the same time, the board structure of the current bill calculation board is a single plate, which is difficult to stand stably on the seat surface. It is mostly laid flat when in use, which is not convenient when calculating and viewing the bill data at the same time. Therefore, those skilled in the art provide a bill calculation board that is easy to clamp to solve the problems raised in the above background technology. Utility Model Content

[0003] The purpose of the utility model is to solve the shortcomings existing in the prior art, and to propose a bill calculation board that is easy to clamp. The board is provided with an expandable back panel so that the board can be tilted and placed on a desktop, so that the data of the bill can be viewed more conveniently and the work efficiency can be improved. A clamping spring is provided to clamp the flipped bill to prevent the bill from falling back and interfering with the work.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] A bill-holding calculation board, comprising a board body, a bill clip fixedly connected to the upper side of the front end surface of the board body, a connector fixedly connected to the upper side of the rear end surface of the board body, and a clamping spring fixedly connected to the upper end of the connector;

[0006] A back groove is provided at the lower side of the rear end surface of the plate body, a back plate is rotatably connected inside the back groove, a plurality of slots are evenly spaced at the middle of the back plate, a matching groove is provided at the middle of the back groove, a support rod is provided inside the matching groove, and the upper end of the support rod is rotatably connected to the matching groove;

[0007] Through the above technical solution, the back panel can be unfolded and used as a base, so that the board can be tilted and placed on the desktop, which makes it more convenient to view the data of the bill and improves work efficiency. A clamping spring can be used to clamp the flipped bill, thereby preventing the bill from falling back and interfering with work.

[0008] Furthermore, the upper end of the clamping spring is fixedly connected with an arc-shaped head;

[0009] With the above technical solution, the arc-shaped head is provided to facilitate the user to spread the clamping spring sheet with his fingers and put the bill into the inner side of the clamping spring sheet when using.

[0010] Furthermore, a hanging hole is provided at the middle of the arc-shaped head;

[0011] Through the above technical solution, the provided hanging hole makes it easy to hang the computing board on the hook.

[0012] Furthermore, a rotating groove is provided at the lower side of the back groove, a rotating head is fixedly connected to the lower end of the back plate, and the rotating head is rotatably connected to the rotating groove;

[0013] Through the above technical solution, the back plate can be smoothly rotated out and put into the back groove by means of the provided rotating head and rotating groove.

[0014] Furthermore, elastic bands are provided on both sides of the outer end of the back plate, and both ends of the elastic bands are fixedly connected to the back plate;

[0015] Through the above technical solution, the elastic bands arranged on both sides of the back panel make it convenient to hold the computing tablet. The hand is inserted into the inner side of an elastic band to prevent it from falling. At the same time, when the back panel is unfolded, the elastic band with a relatively rough surface contacts the desktop, which can also play an anti-slip role, thereby improving the stability when placed upright and having strong practicality.

[0016] Furthermore, a clamping block is rotatably connected to the rear end surface of the plate body near the upper end of the back groove, and one end of the clamping block is in contact with the outer surface of the back plate;

[0017] Through the above technical solution, the card block is rotated to separate it from the back panel, thereby unlocking the back panel. After the back panel is retracted, the card block is rotated downward to lock the back panel, making it difficult to separate.

[0018] Furthermore, the four corners of the plate body are all configured to be arc-shaped;

[0019] With the above technical solution, if the plate body with arc-shaped corners collides with a human body during use, it is not easy to injure the human body.

[0020] Furthermore, an arc-shaped groove is provided at the middle of the outer side of the matching groove;

[0021] Through the above technical solution, the arc-shaped groove is provided to facilitate taking out the support rod inside the matching groove.

[0022] The utility model has the following beneficial effects:

[0023] 1. The utility model proposes a bill calculation board that is easy to clamp. The back of the bill calculation board is provided with an unfoldable backboard. When in use, the unfolded backboard is supported by a support rod, which can provide support so that the board can be tilted and placed on a desktop. When the user is calculating, the data of the bill can be viewed more conveniently, which improves work efficiency. The backboard and the support rod can be completely retracted into the back slot, which takes up little space and is easy to carry.

[0024] 2. The utility model proposes a bill calculation board that is easy to clamp. The bill calculation board is provided with a clamping spring sheet on the upper side of the back. After a bill is used, the bill can be turned over and the lower end of the bill can be clamped by the clamping spring sheet, thereby preventing the bill from falling back after use and interfering with work, making it more convenient to use.
