Description

Technical Field

[0001] This utility model relates to the field of scanning and acquisition devices, and in particular to a height-adjustable art scanning and acquisition device. Background Technology

[0002] Artwork scanning and acquisition devices can capture image information of artworks at high resolution and high precision, restoring the colors, details and textures of the artworks to the greatest extent. For example, large-format scanners (such as the RED500) can achieve image acquisition of up to 1 billion pixels, ensuring that the details of the artworks are fully recorded.

[0003] The scanning and acquisition device is mounted on a support. The height of the scanning and acquisition device can be adjusted by height adjustment to ensure that the device is at a suitable height relative to the artwork. For example, Chinese Patent Publication No. CN216057154U discloses a height-adjustable artwork scanning and acquisition device, which includes a slide rail, a sliding seat, a mounting base, and lamp arms. The slide rail includes a pair of parallel sliding rods with at least two connecting rods between them. The sliding seat includes a fixed seat and sliders that are respectively engaged with the corresponding sliding rods at both ends. The mounting base includes a rod with a square cross-section and a mounting plate sleeved on the rod. A square groove is formed on any side of the rod along its length. A driven wheel is rotatably mounted at the upper end of the square groove, and a driving wheel is rotatably mounted at the lower end of the square groove. The driven wheel and the driving wheel are connected by a belt drive. A drive motor is mounted on the rod, and the mounting plate is fixedly connected to the belt. A pair of lamp arms are provided, symmetrically arranged on both sides of the mounting base, and each lamp arm is equipped with a lighting lamp. The drive motor rotates forward or backward, driving the drive wheel to rotate forward or backward. The drive wheel and the driven wheel work together to achieve belt transmission, which in turn drives the mounting plate to rise or fall.

[0004] In actual operation, the rod can adjust the height of the mounting plate on the scanning device, but it cannot adjust the scanning angle of the scanning device. The fixed angle may result in a limited scanning range, some areas may not be captured, and the scanning angle cannot be adjusted according to the size, shape or shooting requirements of different objects, which limits the versatility of the scanning device. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-4 A height-adjustable artwork scanning and acquisition device includes a base 1 and a gimbal bracket 2. The base 1 is fixedly connected to a support unit. A pair of rods 3 are provided on the top of the base 1. The pair of rods 3 are connected in an inner and outer sleeve and fixed together by a height adjustment component 4. An angle adjustment component 5 is provided on the free end of the inner rod 3. The inner rod 3 is connected to the gimbal bracket 2 through the angle adjustment component 5.

[0023] In some embodiments, the gimbal bracket 2 is used to fix the scanning device. In the prior art, the gimbal bracket 2 itself can be adjusted to a certain extent. Therefore, the height adjustment component 4, together with the angle adjustment component 5, can further improve the adjustment range of the height and angle of the gimbal bracket 2.

[0024] The base 1 can be fixed to the support unit by a pair of clamps and locking bolts. The support unit can be a mobile bracket with casters or a support rod, etc.

[0025] Furthermore, the height adjustment component 4 includes a positioning glass bead 41, a pair of rods 3 are slidably connected, and the positioning glass bead 41 is embedded in the bottom of the inner rod 3;

[0026] The outer rod 3 is fixedly connected to the base 1. The outer wall of the outer rod 3 has several positioning holes 42 evenly distributed along its length. The telescopic column end of the positioning glass bead 41 is engaged in the positioning hole 42.

[0027] In this embodiment, after pressing the telescopic end of the positioning glass bead 41 to retract and disengage it from the positioning hole 42, the height between the pair of rods 3 can be adjusted in multiple levels by stretching the rod 3 of the inner sleeve. Similarly, after the telescopic end of the positioning glass bead 41 is engaged in the positioning hole 42, the height of the pair of rods 3 can be fixed.

[0028] Furthermore, the angle adjustment component 5 includes a clamp 51, with the inner end of the rod 3 rotatably connected to the clamp 51. The end of the inner rod 3 is fixedly connected to a support 52 below the clamp 51, and a movable part 54 is slidably connected via a compression spring 53. The movable part 54 and the rod 3 are circumferentially locked. The circumferential locking method can be achieved by setting a protrusion inside the movable part 54 and a straight groove on the outer side of the rod 3. The sliding and circumferential locking purposes are achieved through the cooperation of the straight groove and the protrusion.

[0029] More specifically, the clamp 51 and the movable part 54 have continuous recesses 511 and protrusions 541 on their opposite sides, respectively. The recesses 511 and the protrusions 541 form a matching triangular structure and are abutted and slid together by guide slopes.

[0030] In this embodiment, the compression spring 53 is sleeved on the periphery of the rod 3, and the two ends of the compression spring 53 abut against the support part 52 and the movable part 54 respectively. The compression spring 53 is used to provide upward elastic support for the movable part 54.

[0031] Specifically, the compression spring 53 provides sufficient elastic support to the movable part 54 so that the protrusion 541 is locked in the recess 511, thereby preventing the clamp 51 from rotating freely and achieving the function of circumferential locking of the clamp 51.

[0032] More specifically, by twisting the clamp 51 to make it rotate, and because the recessed part 511 and the protruding part 541 can slide against each other through the guide slope, when the rotational force generated by twisting is greater than the supporting force applied by the compression spring 53 to the movable part 54, the angle of the clamp 51 can be adjusted.

[0033] In general, the top of the clamp 51 is recessed along the centerline to form a movable groove 512, the two side walls of the movable groove 512 are recessed to form spherical grooves 513, and the top of the clamp 51 extends downward along the centerline and connects to one side wall to form a first clamping part 6 and a second clamping part 7.

[0034] Finally, the gimbal bracket 2 has a connecting rod 21, the free end of which is provided with a spherical part 22. The connecting rod 21 is slidably connected in the movable groove 512, and the spherical part 22 is movably connected in the spherical groove 513.

[0035] The first clamping part 6 and the second clamping part 7 are fastened together by fasteners 8 to lock the spherical part 22.

[0036] In this embodiment, the fastener 8 is a locking bolt. The locking bolt passes through the first clamping part 6 and is threadedly connected to the second clamping part 7 to lock and fix the first clamping part 6 and the second clamping part 7. After locking and fixing, the pair of clamping parts can hug the spherical part 22 through the spherical groove 513 to fix the angle of the gimbal bracket 2.

[0037] Specifically, after the pair of clamping parts are unlocked, the spherical part 22 can move freely, and the connecting rod 21 can slide along the movable groove 512.

[0038] Working method: During operation, the base 1 is fixedly connected to the support unit. After pressing the telescopic column end of the positioning glass bead 41 to make it retract and disengage from the positioning hole 42, the height between the pair of rods 3 can be adjusted in multiple stages by stretching the rod 3 of the inner sleeve. After the telescopic column end of the positioning glass bead 41 is engaged in the positioning hole 42, the height of the pair of rods 3 can be fixed.

[0039] Then, after the fastener 8 is twisted to relax the first clamping part 6 and the second clamping part 7, the spherical part 22 is slidably connected in the spherical groove 513, and the connecting rod 21 can slide along the movable groove 512. The pair of clamping parts can be clamped by the fastener 8 to fix the spherical part 22.

[0040] Finally, the clamp 51 can be rotated directly. When the rotational force generated by the twisting is greater than the supporting force applied by the compression spring 53 to the movable part 54, the angle of the clamp 51 can be adjusted.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
