DETAILED DESCRIPTION

[0023] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0024] Example

[0025] like Figure 1 - Figure 7 As shown, a handheld wireless two-dimensional code scanner includes an upper shell 1 and a lower shell 2 detachably connected by a connecting piece, and a handheld portion 3 is integrally formed at the same end of the upper shell 1 and the lower shell 2. The handheld portion 3 is provided to facilitate the user to hold the code scanner through the handheld portion 3 to perform code scanning. The handheld portion 3 includes an upper grip integrally formed with the upper shell 1 and a lower grip integrally formed with the lower shell 2. The connecting piece includes two groups of clamping rings 4 fixedly connected in the inner cavity of one end of the upper shell 1 away from the upper grip, and also includes two groups of clamping columns 5 fixedly connected at one end of the lower shell 2 away from the lower grip. The two groups of clamping columns 5 are arranged in opposition to the two groups of clamping rings 4. When assembling, the upper shell 1 and the lower shell 2 can be moved so that the clamping rings 4 correspond to the clamping columns 5 one by one. At this time, the upper shell 1 and the lower shell 2 are pressed toward each other, so that the clamping columns 5 can be inserted into the clamping rings 4, so that the upper shell 1 and the lower shell 2 are clamped together by the clamping columns 5 and the clamping rings 4 to form an integral structure;

[0026] A microprocessor 6 is installed in the inner cavity of the upper shell 1, and a scanning structure is installed on the upper shell 1. The scanning structure is a scanning head 7 electrically connected to the microprocessor 6 installed on the outer wall of the upper shell 1 at one end away from the upper handle. When scanning a two-dimensional code, the scanning head 7 can be aimed at the two-dimensional code, and the two-dimensional code image is scanned by the scanning head 7, and the image information is transmitted to the microprocessor 6;

[0027] A partition 8 is provided between the inner cavity of the upper shell 1 and the inner cavity of the upper handle, and a receiving cavity is formed between the partition 8 and the inner wall of the upper handle. A decoder 9 is installed in the receiving cavity. A wire 10 with an intermediate section penetrating the partition 8 is provided between the microprocessor 6 and the decoder 9. The microprocessor 6 and the decoder 9 are electrically connected through the wire 10. After receiving the two-dimensional code image information scanned by the scanning head 7, the microprocessor 6 transmits the information to the decoder 9 for decoding, so as to identify the information of the two-dimensional code image, and retransmits the decoded information to the microprocessor 6;

[0028] A display screen 11 is installed on the upper surface of the upper housing 1, and a control button 12 is installed on the upper surface of the upper handle. The display screen 11 and the control button 12 are both electrically connected to the microprocessor 6. The control button 12 is used to control the scanning head 7 to scan. When the microprocessor 6 receives the decoded information transmitted by the decoder 9, the decoded information is transmitted to the display screen 11 and displayed on the display screen 11.

[0029] Slide tubes 16 made of magnetic material are fixedly connected in the inner cavity of the lower shell 2 on both sides of the handheld part 3. One end of the slide tube 16 close to the handheld part 3 passes through the side wall of the lower shell 2 and is fixed to the side wall of the lower shell 2. Two symmetrically arranged limit clamps 13 are fixedly connected to the inner wall of the lower shell 2 on the adjacent sides of the two slide tubes 16. A lithium battery 14 is arranged between the two limit clamps 13. Both sides of the lithium battery 14 are respectively attached to the adjacent sides of the two limit clamps 13. A charging interface 15 electrically connected to the lithium battery 14 is also arranged on the lower shell 2. The lithium battery 14 is used to power the scanning head 7, the microprocessor 6, the decoder 9 and the display screen 11. The limit clamp 13 is used to clamp and fix the lithium battery 14 to avoid the lithium battery 14 from shaking in the lower shell 2 as much as possible. The charging interface 15 electrically connected to the lithium battery 14 is arranged on the lower shell 2 for charging the lithium battery 14;

[0030] A shielding sleeve 17 is provided on a section of the outer surface of the slide tube 16 located in the inner cavity of the lower shell 2. The shielding sleeve 17 is made of a graphene material with a three-dimensional honeycomb mesh structure. Since the slide tube 16 is made of a magnetic material, a magnetic field will be generated on its surrounding side, which may affect the operation of the scanning gun. The shielding sleeve 17 made of graphene with a three-dimensional honeycomb mesh structure can reflect and absorb electromagnetic waves multiple times through its internal structure, achieving ultra-high electromagnetic shielding performance, so as to prevent the slide tube 16 from interfering with the operation of the scanning gun;

[0031] A slide bar 18 is slidably connected in the inner cavity of the slide tube 16. The slide bar 18 is a round rod-shaped structure. The slide bar 18 is made of metal that can be adsorbed by magnetic materials, and the length of the slide bar 18 is not greater than the length of the slide tube 16. Since the slide bar 18 is made of metal that can be adsorbed by magnetic materials, when the slide bar 18 slides to any position, it can be adsorbed on the inner wall of the slide tube 16 by the action of the magnetic field force to achieve relative fixation with the slide tube 16. The length of the slide bar 18 is set to be not greater than the length of the slide tube 16, so that the slide bar 18 can slide into the slide tube 16 until it is completely embedded in the slide tube 16, so as to achieve the storage of the slide bar 18, thereby reducing the volume of the overall device and increasing the portability of the overall device.

[0032] A connecting seat 19 is fixedly installed at one end of the slide bar 18 located outside the slide tube 16, and the two connecting seats 19 are arranged in opposition. A fixing belt 20 with an arc-shaped structure is arranged between the two connecting seats 19, and connecting shafts 21 rotatably connected to the fixing belt 20 are passed through both ends of the fixing belt 20. The connecting shaft 21 passes through the end of the fixing belt 20 and is fixed to the corresponding connecting seat 19. An elastic belt 22 is also fixedly connected between the two ends of the fixing belt 20. When in use, the user can put the fixing belt 20 and the elastic belt 22 on the arm, and adjust the position of the fixing belt 20 and the elastic belt 22 by sliding the slide bar 18, so that the fixing belt 20 and the elastic belt 22 are stably fixed to the user's arm, and the user's arm can cooperate with the slide bar 18 to provide auxiliary support for the entire scanning gun to relieve the pressure on the user's wrist.

[0033] It should be noted that when using this handheld wireless two-dimensional code scanner, the user first pulls the slide bar 18 toward the slide tube 16, pulls out one end of the slide bar 18 connected to the fixing belt 20 and the elastic belt 22, and then puts the fixing belt 20 and the elastic belt 22 on the arm, and adjusts the position of the fixing belt 20 and the elastic belt 22 by sliding the slide bar 18, so that the fixing belt 20 and the elastic belt 22 are stably fixed to the user's arm, and then the scanning head 7 can be aligned with the two-dimensional code to be scanned, and the scanning head 7 is turned on by the control button 12 to scan the two-dimensional code image. After scanning the code, the scanning head 7 transmits the two-dimensional code image to the microprocessor 6 installed in the upper shell 1, and the image information is transmitted to the microprocessor 6 through the wire 10. The decoder 9 decodes, and after the decoding is completed, the decoder 9 retransmits the decoded information to the microprocessor 6, and transmits the decoded information to the display screen 11 installed on the upper shell 1 for display through the microprocessor 6. During the scanning process, the lower shell 2 is fixed to the user's arm through the slide bar 18, the fixing belt 20 and the elastic belt 22, so that the user's arm can assist in supporting the entire scanner to relieve the pressure on the user's wrist, and try to avoid the problem that the existing handheld two-dimensional code scanner is generally only supported by the user's hand. Since the gravity of the scanner is completely applied to the user's wrist, when used for a long time, it will cause soreness in the user's wrist, which is inconvenient for the user to continue scanning for a long time.

[0034] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
