Description

Technical Field

[0001] The utility model relates to a barcode scanning gun. Background Art

[0002] In the library, a scanner is needed to scan the books and put them into the library, so that the area where the books are located can be determined based on the scanning results, which is convenient for returning the books to their original locations later. The scanner is also used to collect data statistics on the books that are in and out of the library.

[0003] In the prior art, the scanners in libraries are handheld scanners. During the book scanning process, a QR code or a barcode is printed on the back of the book, which needs to be scanned by a scanner. However, when a single person operates, the scanner needs to be held and the book needs to be turned over, which is cumbersome to operate. Especially for heavy books, it is difficult to turn them over with one hand, especially for female administrators. Therefore, they need to put down the scanner, turn the book over with both hands, and then scan it, which takes a long time.

[0004] Based on the above problems, we designed a barcode scanner that can achieve fixed-position scanning without the need for handheld operation. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a barcode scanning gun which can realize fixed position scanning and does not require hand-held operation.

[0026] like Figure 1 and Figure 2 The barcode scanning gun shown includes a scanning head 1, and the scanning head 1 is equipped with a handle 2. A press-triggered button switch 21 is installed on the inner side of the handle 2. The button switch 21 has two operating modes, one is a single click, which scans once when pressed, and the other is a continuous press. When pressed continuously, the scanning head 1 is in an intermittent scanning state, and the interval time of each scan is 0.5 to 1.5 seconds. It also includes a bracket device 3 connected to a table, and a book board device 4 installed through the bracket device 3. The scanning head 1 is installed through the bracket device 3. After the installation is completed, the scanning position of the scanning head 1 corresponds to the book board device 4.

[0027] The above technical solution has two operation modes:

[0028] The first method is to use only the scanning head 1 to perform scanning operations, and scan the barcode or QR code by pressing the button switch 21, which is mainly for the case where the amount of books is not large.

[0029] The second method is to assemble the scanning head 1 with the bracket device 3. At this time, the books to be scanned slide along the book board device 4 and are directly scanned and read when they slide to the scanning area of ​​the scanning head 1. This method is suitable for situations where there are a large number of books.

[0030] See also Figure 1 , Figure 3 and Figure 4 As shown, the bracket device 3 includes a bracket body 31, a clamp 32 for clamping a table is provided at the inner bottom position of the bracket body 31, a bolt 33 for fixing is screwed upward at the bottom of the clamp 32, a first clamp 34 for installing the book board device 4 is provided at the inner middle position of the bracket body 31, a first bolt 35 is matched between the first clamp 34 and the book board device 4, a support ring 36 for supporting the scanning head is provided on the top of the bracket body 31, a groove 37 for fitting the handle 2 is provided on the outside of the bracket body 31, the groove 37 penetrates the support ring 36, slots 38 are provided on the groove walls on both sides of the groove 37, a locking plate 39 is inserted in the slot 38, and one end of the locking plate 39 extends to the slot 38 On the outside, a spring 310 is installed at the other end, and the spring 310 acts on the end of the slot 38. Under the action of the spring 310, the locking piece 39 pops outward along the slot 38, and a slide groove 311 connected to the slot 38 is arranged on the top of the bracket body 31, and a slide rod 312 is arranged in the slide groove 311. The lower end of the slide rod 312 is screwed into the locking piece 39, and the slide rod 312 forms a limit for the sliding of the locking piece 39; locking grooves 22 for fitting the locking piece 39 are arranged on both sides of the handle 2, and when the locking piece 39 and the locking grooves 22 are matched, the button switch 21 acts on the bottom of the groove 37 and is in a pressed state; when the scanning head 1 is matched in the supporting ring 36, the scanning head 1 scans downward.

[0031] In the above technical solution, the handle 2 is clamped and fixed by the cooperation of the locking plate and the locking groove, and the button switch 21 is in a pressed state. At this time, the scanning head 1 faces downward to the book board device 4 and continues to scan the passing books.

[0032] See also Figure 5 As shown, the book board device 4 includes a book board 41 , the book board 41 is inserted into the first clamping opening 34 , and the scanning head 1 corresponds to the book board 41 .

[0033] The book plate to be scanned slides along the book plate 41 and is read when it passes through the scanning area of ​​the scanning head 1 .

[0034] See also Figure 5As shown, two sliding holes (not shown) are provided on the upper part of the book board 41, and the sliding holes are close to the edges of the book board. A first sliding rod 42 is fitted through the sliding holes, and a nut 43 is fitted at the lower end of the first sliding rod 42. A connecting plate 44 is provided at the upper end of the first sliding rod 42, and a spring 45 is provided on the first sliding rod 42. The spring 45 acts between the book board 41 and the nut 43. Under the action of gravity, the first sliding rod 42 descends to the connecting plate 44 to act on the book board 41, and a book pressing plate 46 is fitted between the two connecting plates 44, and the scanned book passes under the book pressing plate 46.

[0035] When some books are wrinkled, they will be pried up. When pried up, the barcode will be deformed or tilted, making it impossible for the scanning head 1 to read it effectively. The book can be flattened by the above-mentioned book pressing plate 46 to facilitate reading of the barcode or QR code. During specific operation, one end of the book is sealed and the other end can be turned. The sealed end first enters under the book pressing plate 46. The barcode or QR code of the book is in a position close to the book pressing plate 46, which is convenient for the scanning head 1 to scan.

[0036] See also Figure 5 As shown, one end of the book pressing plate 46 is provided with an inclined plate portion 466, and the scanned book slides in from the inclined plate portion. When sliding in, the book pressing plate is lifted up, and at this time, the first slide bar moves upward, and the spring is compressed.

[0037] In the above technical solution, the inclined plate portion 466 facilitates sliding into the vertical plate.

[0038] See also Figure 5 As shown, a limiting plate 441 is provided on the plate surface of the book plate 41, and the limiting plate 441 is located on the side of the book pressing plate 46. The scanned book is limited by the limiting plate, and the book slides in from the inclined plate part after sliding horizontally along the limiting plate.

[0039] The limiting plate 441 can limit the vertical plate, so that the sliding position of the book is more accurate.

[0040] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
