Description

Technical Field

[0001] The utility model relates to the technical field of hand-held scanning devices, and particularly relates to a hand-held scanning device with an anti-detachment structure. Background Technique

[0002] Hand-held scanning devices are applied in various industries, and their functions vary in different industries. In some industries where the operation time of hand-held scanning devices is relatively long, such as the express delivery industry, when the hand-held scanning device is held for too long, people's hands will become sore and numb, so the hand-held scanning device may fall off.

[0003] In the "Portable Scanning Gun for Logistics Warehousing" with the authorization announcement number of "CN 218471315 U", it includes a scanning gun body. A hand-held grip is fixedly installed at the lower part of the scanning gun body. An anti-detachment device is arranged on the rear surface of the hand-held grip. The anti-detachment device includes an elastic structure, an anti-detachment support arm and an elastic rubber block. The lower part of the elastic structure is movably installed with the anti-detachment support arm. An elastic rubber block is fixedly installed on the inner wall of the anti-detachment support arm. The elastic structure includes a spring sleeve, a guiding sliding plate and a return spring. The guiding sliding plate is movably installed inside the spring sleeve, and the return spring is movably installed inside the spring sleeve.

[0004] In the above-mentioned prior art, the user needs to insert the finger into the hand-held opening between the anti-detachment support arm and the hand-held grip. However, when inserting the finger into the hand-held opening, it is necessary to insert the whole finger between the elastic rubber block and the hand-held grip. Sometimes, it is necessary to move the position of the elastic rubber block to insert the whole finger between the elastic rubber block and the hand-held grip, which is inconvenient for people to use. At the same time, only the finger is fixed between the elastic rubber block and the hand-held grip, and the back of the hand is not fixed, so the palm is still easy to fall off from the hand-held scanning device, and the anti-detachment effect is poor.

[0023] When the finger presses the inclined surface 4, it will drive the installation plate 7 installed with the elastic rubber block 3 to slide along the four first limiting rods 6. At this time, the first compression spring 9 is in a compressed state. Then, the whole finger passes through one side of the elastic rubber block 3, and the finger will be fixed between the elastic rubber block 3 and the handle 2 under the extrusion of the first compression spring 9 on the installation plate 7, which is convenient for fixing the position of the finger.

[0024] As Figures 1 to 4 shown, a clamping groove 10 for clamping the finger position is arranged on the side of the elastic rubber block 3 away from the installation plate 7.

[0025] The finger can be clamped inside the clamping groove 10 for limiting the finger of people.

[0026] As Figures 1 to 4 shown, a motor 11 is fixedly installed inside the top end of one side of the handle 2. The output end of the motor 11 is fixedly installed with a screw rod 12.

[0032] The present utility model provides a handheld scanning device with an anti-detachment structure, and the specific working principle is as follows:

[0033] When the device is in use, squeezing the inclined surface 4 with a finger will drive the mounting plate 7 equipped with the elastic rubber block 3 to slide along the four first limiting rods 6. At this time, the first compression spring 9 is in a compressed state. Then, passing the entire finger through one side of the elastic rubber block 3, the finger will be fixed between the elastic rubber block 3 and the handle 2 under the extrusion of the first compression spring 9 on the mounting plate 7, facilitating the fixation of the finger position.

[0034] Then, driving the screw rod 12 to rotate through the motor 11, and driving the lifting plate 14 to descend through the threaded connection between the screw rod 12 and the lifting plate 14 and the control of the second limiting rod 13 on the lifting plate 14. Further driving the control plate 5 to descend, the control plate 5 can position the back of the hand to prevent the palm of people from slipping out between the elastic rubber block 3 and the control plate 5, so as to improve the anti-detachment effect of the hand.
