Description

Technical Field

[0001] The utility model relates to the technical field of code scanners, and in particular to a platform-type code scanner. Background Art

[0002] A platform-type barcode scanner generally includes a barcode scanning module and a base. Since the barcode scanning module can be placed on the desktop through the base, both hands can be freed, which improves the scanning speed and timeliness. In order to facilitate the barcode scanning module to align with the position of the barcode or QR code, the existing platform-type barcode scanner usually sets a rotating structure between the barcode scanning module and the base, so that the barcode scanning module can rotate a certain angle relative to the base.

[0003] However, the existing platform-type barcode scanners still have the following technical problems: since the barcode scanning module usually needs to stay at the adjusted position after rotating a certain angle relative to the base, the rotating structure must not only enable the barcode scanning module to rotate relative to the base, but also be able to reliably realize the follow-stop function during the rotation process. The existing rotating structure that realizes the above-mentioned follow-stop function usually arranges a matching structure of an arc-shaped rack and a gear between the bottom of the barcode scanning module and the base. The matching structure of the arc-shaped rack and the gear is not smooth enough, makes loud noises, and has strong friction when rotating, which leads to a poor user experience, easy wear between parts, and a short service life of parts. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a platform-type code scanner with smoother rotation, lower noise and reduced friction.

[0005] The technical solution of the utility model is: a platform-type code scanner, including a base and a code scanning module, the upper part of the base is provided with a concave surface open upward, and the base and the two sides of the concave surface are respectively fixed with a first side plate and a second side plate, the code scanning module is clamped between the first side plate and the second side plate and the bottom of the code scanning module is concavely matched with the concave surface; one side of the code scanning module is rotatably connected to the first side plate through a stop-rotation shaft structure, and the other side of the code scanning module is rotatably connected to the second side plate through a connecting shaft structure; one end of the connecting shaft structure is fixedly connected to the corresponding side of the code scanning module, and the other end is provided with a snap structure, and the connecting shaft structure passes through the second side plate and is snap-connected to the outer side wall of the second side plate through the snap structure.

[0006] After adopting the above structure, the utility model has the following advantages:

[0007] The scanning module of the platform-type barcode scanner of the utility model realizes the rotation on the base through the stop-following shaft structure and the connecting shaft structure on the left and right sides. Since the stop-following shaft structure can stop at any time during the rotation, and the connecting shaft structure rotates following the stop-following shaft structure and a snap structure is provided on the connecting shaft structure, the snap structure is conducive to ensuring that the connecting shaft structure follows the stop-following shaft structure to stop reliably, and on the other hand, it can prevent the scanning module from escaping laterally. Since the shaft structures on both sides of the scanning module can stop reliably during the rotation, the stop-following function of the scanning module during the rotation process is reliably realized. Compared with the existing arc-shaped rack and gear structure, the stop-following shaft structure and the connecting shaft structure are used to realize the rotation structure with the stop-following function. Obviously, the rotation is smoother, the noise is smaller, and the friction is reduced, thereby improving the user experience, reducing the wear between parts, and extending the service life of parts.

[0008] Preferably, the connecting shaft structure includes a shaft body, and the buckle structure includes a claw arranged outwardly in the radial direction of the outer wall of the shaft body, one end of the shaft body is fixedly connected to the corresponding side of the code scanning module, and the other end passes through the second side plate and is buckled with the outer wall of the second side plate through the claw. The buckle structure is simple and easy to process.

[0009] Preferably, the plurality of claws are evenly spaced along the circumferential direction of the shaft body, and a slot is provided between two adjacent claws. The plurality of claws provide a more secure clamping connection, and the slot is provided between two adjacent claws to provide elastic space on both sides of the claws, making the clamping connection more convenient.

[0010] Preferably, a limit slider is provided on the shaft body, and a limit slot matching the limit slider is provided on the second side plate. When the code scanning module rotates relative to the base, the limit slider rotates within the range limited by the limit slot. This setting uses the limit slider and the limit slot to limit the rotation angle of the code scanning module, which has a simple structure and reliable limit.

[0011] Preferably, the limiting slide groove is an arc-shaped structure, and the limiting slide groove is coaxially arranged with the shaft body in the circumferential direction, and the symmetric midline of the limiting slide groove is used as the reference line, and the rotation angle range of the limiting slider in the limiting slide groove is -20° to +20°. This setting can make the limiting slide groove cooperate well with the limiting slider on the shaft body, thereby ensuring that the limiting slider rotates stably, reliably and smoothly in the limiting slide groove.

[0012] Preferably, the second side plate is provided with an axial hole matched with the shaft body, a mounting ring is fixed in the axial hole, a notch is provided on the mounting ring along its axial direction, when the mounting ring is installed in the axial hole, the notch and the inner wall of the axial hole are combined to form the limiting slide groove. This arrangement facilitates the formation of the limiting slide groove, and the structure is simple and compact.

[0013] Preferably, the outer side wall of the assembly ring is convexly arranged on the outer side wall of the second side plate, so that the clamping claw is clamped on the outer side wall of the assembly ring. This arrangement can make the length of the clamping claw longer, making it more convenient to install the buckle structure.

[0014] Preferably, the limit slider is arranged outwardly along the radial direction of the outer wall of the shaft body, and the limit slot is arranged as a through slot along the axial direction of the shaft hole. This arrangement can reduce the friction surface between the limit slider and the limit slot, further making the rotation smoother, with less friction and less noise.

[0015] Preferably, the limiting slider axially penetrates the limiting slot, which can ensure stable and reliable cooperation between the limiting slider and the limiting slot.

[0016] Preferably, the code scanning module comprises a spherical shell, the bottom of which is concave-convexly matched with the concave surface of the base. The spherical shell is easy to achieve concave-convex matching with the base.

[0017] Preferably, the spherical shell is formed by detachably splicing two half shells. The spherical shell is formed by detachably splicing two half shells to facilitate the installation of internal components. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] Example:

[0026] like Figure 1-5 As shown, a platform-type code scanner includes a base 1 and a code scanning module 2. The upper part of the base 1 is provided with a concave surface 3 open upward. The base 1 is also fixed with a first side plate 16 and a second side plate 4 on both sides of the concave surface 3. In this embodiment, the first side plate 16 and the second side plate 4 are integrally formed with the base 1, and the code scanning module 2 is clamped between the first side plate 16 and the second side plate 4, and the bottom of the code scanning module 2 is concavely matched with the concave surface 3; one side of the code scanning module 2 is rotatably connected to the first side plate 16 through a stop-rotation shaft structure 5, and the other side of the code scanning module 2 is rotatably connected to the second side plate 4 through a connecting shaft structure 6; one end of the connecting shaft structure 6 is fixedly connected to the corresponding side of the code scanning module 2, and the other end is provided with a snap structure 7, and the connecting shaft structure 6 passes through the second side plate 4 and is snap-connected to the outer wall of the second side plate 4 through the snap structure 7.

[0027] The scanning module 2 of the platform-type barcode scanner of the utility model realizes the rotation on the base 1 through the stop-following shaft structure 5 and the connecting shaft structure 6 on the left and right sides. Since the stop-following shaft structure 5 can stop at any time during the rotation, and the connecting shaft structure 6 rotates following the stop-following shaft structure 5 and a snap structure 7 is provided on the connecting shaft structure 6, the snap structure 7 is conducive to ensuring that the connecting shaft structure 6 follows the stop-following shaft structure 5 to stop reliably on the one hand, and can prevent the scanning module 2 from escaping laterally on the other hand. Since the shaft structures on both sides of the scanning module 2 can stop reliably during the rotation, the stop-following function of the scanning module 2 during the rotation process is reliably realized. Compared with the existing arc-shaped rack and gear structure, the rotation structure with the stop-following shaft structure 5 and the connecting shaft structure 6 are adopted, which obviously rotates more smoothly, makes less noise, and reduces friction, thereby improving the user experience, reducing the wear between parts, and extending the service life of parts.

[0028] The connecting shaft structure 6 includes a shaft body 13, and the buckle structure 7 includes a claw 8 arranged outwardly along the radial direction of the outer wall of the shaft body 13. One end of the shaft body 13 is fixedly connected to the corresponding side of the code scanning module 2, and the other end passes through the second side plate 4 and is buckled with the outer wall of the second side plate 4 through the claw 8. The buckle structure 7 is simple and easy to process.

[0029] The plurality of claws 8 are evenly spaced along the circumferential direction of the shaft body 13, and a slot 12 is provided between two adjacent claws 8. In this embodiment, two claws 8 are provided. The plurality of claws 8 are provided, and the clamping is more secure. The slot 12 is provided between two adjacent claws 8, so that both sides of the claws 8 have elastic space, and the clamping is more convenient.

[0030] A limit slider 9 is provided on the shaft body 13, and a limit slot 10 matching the limit slider 9 is provided on the second side plate 4. When the code scanning module 2 rotates relative to the base 1, the limit slider 9 rotates within the range limited by the limit slot 10. This setting uses the limit slider 9 and the limit slot 10 to limit the rotation angle of the code scanning module 2, and has a simple structure and reliable limit.

[0031] The limiting slide groove 10 is an arc-shaped structure, and the limiting slide groove 10 and the shaft body 13 are coaxially arranged in the circumferential direction. With the symmetric midline of the limiting slide groove 10 as the reference line, the rotation angle range of the limiting slider 9 in the limiting slide groove 10 is -20° to +20°. This arrangement can make the limiting slide groove 10 cooperate well with the limiting slider 9 on the shaft body 13, thereby ensuring that the limiting slider 9 rotates stably, reliably and smoothly in the limiting slide groove 10.

[0032] The second side plate 4 is provided with an axial hole 14 matched with the shaft body 13, and a mounting ring 15 is fixed in the axial hole 14. A notch is provided on the mounting ring 15 along its axial direction. When the mounting ring 15 is installed in the axial hole 14, the notch and a part of the inner wall of the axial hole 14 are enclosed to form a limiting slide groove 10. This arrangement facilitates the formation of the limiting slide groove 10, and the structure is simple and compact.

[0033] The outer side wall of the assembly ring 15 is convexly arranged on the outer side wall of the second side plate 4, so that the claw 8 is clamped on the outer side wall of the assembly ring 15. This arrangement can make the length of the claw 8 longer, and it is more convenient to install the buckle structure 7.

[0034] The limit slider 9 is arranged outwardly along the radial direction of the outer wall of the shaft body 13, and the limit slot 10 is arranged as a through slot along the axial direction of the shaft hole 14. This arrangement can reduce the friction surface between the limit slider 9 and the limit slot 10, further making the rotation smoother, with less friction and less noise.

[0035] The limiting slide block 9 axially penetrates the limiting slide groove 10. This arrangement can ensure the stable and reliable cooperation between the limiting slide block 9 and the limiting slide groove 10.

[0036] The code scanning module 2 includes a spherical shell 11, and the bottom of the spherical shell 11 is matched with the concave surface 3 of the base 1. The spherical shell 11 is easy to achieve the concave-convex match with the base 1.

[0037] The spherical shell 11 is formed by detachably splicing two half shells, and the detachable splicing structure can be a snap connection plus bolt locking. The spherical shell 11 is detachably spliced ​​by two half shells to facilitate the installation of internal components.

[0038] The working principle of the platform-type barcode scanner of the utility model is as follows:

[0039] Rotate the code scanning module 2, the stop shaft structure 5 rotates relative to the first side plate 16 and the connecting shaft structure 6 rotates relative to the second side plate 4, and at the same time, the limit slider 9 rotates in the limit slide groove 10. When it is rotated to a suitable angle, release the code scanning module 2, the stop shaft structure 5 stops rotating immediately, and the connecting shaft structure 6 also quickly follows the stop shaft structure 5 to stop rotating with the cooperation of the buckle structure 7. In this way, the shaft structures on both sides of the code scanning module 2 can be reliably stopped during the rotation process, thereby reliably realizing the stop function of the code scanning module 2 during the rotation process.
