Description

Technical Field

[0001] The utility model relates to the technical field of craft painting relief positioning, in particular to a positioning mechanism for craft painting relief. Background Art

[0002] Craft painting is a kind of artwork made with a variety of rich materials and techniques. Through collage, inlay, painting, casting, forging, lacquering and other craftsmanship, it forms vivid and artistically appealing paintings.

[0003] In the current process of craft painting, artists usually place a plain board on a table to carry out detailed relief painting. Although this method is simple, it has certain technical challenges: if the plain board is too thin, it will be easily disturbed by external forces during the painting process, causing the picture to shift and affecting the final artistic effect. This shift may not only damage the delicate pattern, but also make the entire creation return to the starting point, so stability is crucial in the production process.

[0004] Therefore, we propose a positioning mechanism for craft painting relief. Utility Model Content

[0005] The utility model mainly solves the technical problems existing in the above-mentioned prior art and provides a positioning mechanism for craft painting relief.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a positioning mechanism for craft painting relief, comprising a base and a plain plate, an adjusting seat is arranged on the top of the base, four mounting blocks are fixedly installed on the front side of the adjusting seat, positioning clamps for clamping the plain plate are rotatably installed between two of the mounting blocks through a rotating shaft, a clearance groove is arranged on the front side of the adjusting seat, a positioning screw barrel is fixedly inserted on the rear inner wall of the clearance groove, a guide slide barrel is slidingly sleeved on the front end of the positioning screw barrel, a positioning plate is fixedly installed on the front end of the guide slide barrel, an auxiliary slot is arranged around the outer side wall of the positioning plate, the inner end of each positioning clamp is movably inserted into the auxiliary slot, a clearance hole which passes through the front and back is arranged on the front side of the positioning plate, a positioning stud is inserted into the inner thread of the positioning screw barrel, and a positioning stopper is fixedly installed on the front end of the positioning stud through the clearance hole.

[0007] Furthermore, a mounting frame is fixedly installed on the top of the base, an adjusting cylinder is rotatably inserted on the top of the mounting frame, the rear wall of the adjusting seat is fixedly installed on the front end of the adjusting cylinder, and an adjusting rotary cylinder is fixedly sleeved on the rear end of the adjusting cylinder.

[0008] Furthermore, a mounting bearing is fixedly installed on the inner wall of the adjusting cylinder, a control rod is fixedly inserted on the mounting bearing, the front end of the control rod and the rear end of the positioning stud are fixedly connected, and a positioning knob is fixedly installed on the rear end of the control rod.

[0009] Furthermore, a mounting plate is fixedly installed on the front end of the top of the mounting frame, a locking arm is rotatably installed on the top of the mounting plate through a rotating shaft, a locking block is fixedly installed on the bottom of the rear end of the locking arm, and a plurality of locking slots are provided on the front end of the outer wall of the adjusting rotary cylinder to facilitate the insertion of the locking block.

[0010] Furthermore, a second spring is fixedly mounted on the top of the mounting frame, and the other end of the second spring is fixedly mounted on the bottom surface of the locking arm.

[0011] Furthermore, a first spring is sleeved on the guide slide cylinder, and the front and rear ends of the first spring are respectively in contact with the rear wall of the positioning plate and the rear inner wall of the clearance groove.

[0012] Furthermore, a rubber pad is fixedly mounted on the inner side wall of each positioning clamp.

[0013] Beneficial Effects

[0014] The utility model provides a positioning mechanism for craft painting relief, which has the following beneficial effects:

[0015] 1. A positioning mechanism for craft painting relief. When in use, first put the plain plate between four positioning clamps, and then turn the positioning knob. The positioning knob drives the positioning stud to rotate through the control rod arranged on the mounting bearing. The positioning stud drives the positioning block to move backward through the threaded connection with the positioning screw barrel. The positioning block drives the positioning plate and the guide slide barrel arranged at the rear of the positioning plate to move backward along the positioning screw barrel. The positioning plate drives the positioning clamps arranged between the two mounting blocks to rotate through the auxiliary slots provided on the outer wall. The positioning clamps clamp the plain plate through the rubber pads provided on the inner wall, so that the plain plate can be stably positioned when painting relief, avoiding displacement that causes the relief position drawn out to be different from the expected structure, thereby reducing the defective rate.

[0016] 2. This positioning mechanism is used for craft painting relief. When it is necessary to rotate the plain plate to a certain angle to facilitate painting relief, the rear end of the locking arm arranged on the mounting plate is lifted upward, and the rear end of the locking arm drives the locking block to leave the locking slot, thereby releasing the lock of the adjusting rotary cylinder. The adjusting rotary cylinder is rotated, and the adjusting rotary cylinder drives the adjusting seat to rotate through the adjusting cylinder. The adjusting seat drives the plain plate to rotate through the mounting block and the positioning clamp, thereby realizing the effect of rotating the plain plate after positioning it during the painting relief process to meet various needs of the painting process.

[0017] 3. For the positioning mechanism used in the relief of handicraft paintings, when it is necessary to remove the plain board, rotate the positioning knob in the reverse direction. The first spring rebounds to make the positioning disk move forward, so that the positioning clamp can open outward, releasing the positioning of the plain board. After rotating to the appropriate angle, loosen the rear end of the locking arm. The second spring rebounds to drive the locking block arranged at the rear end of the locking arm to re-engage into the locking slot, completing the fixation of the angle of the plain board. The operation is simple and convenient to use. At the same time, a rubber pad is arranged on the inner side wall of the positioning clamp to reduce the possibility of deformation of the plain board during fixation.
