Description

Technical Field

[0001] The utility model is a sketch anti-erasure ring. Except for the ball bearing, all structural parts are produced by injection molding. Background Art

[0002] In the process of sketching, a large area of ​​color can be painted with a horizontal pen holding method, and the pen can be thrown away for painting. The painter does not need to touch the picture; when depicting in detail, in order to stabilize the hand, the painter usually uses a posture similar to writing, and partially touches the picture with the hand holding the pen. For a few people who have been painting for a long time and have formed good habits, they can open their little fingers and support the picture with the fingertips or knuckles of the little fingers to carefully paint the picture. In this way, the area where the little finger touches the picture is small, it is not easy to smear the picture, and the picture will not stain the hand. Due to personal habits, most people prefer to use a writing posture when drawing sketches, putting the bottom of the hand on the picture for depiction. The area is large, and the hand movement will be more stable and controllable, but the painting hand is very easy to smear the picture during the drawing process. Usually in the depiction process, the hand smears the part of the picture that the hand passes through into a mess, and the bottom of the painting hand is also stained with black by the picture.

[0003] In order to solve the problem of the painting hand easily smearing the picture during the sketching process, the method of using white paper to cover the picture under the painting hand as the painting hand moves is usually adopted. However, this method can only be used when the drawing board is placed horizontally. If the drawing board is placed vertically, the white paper is easy to slide off, and the white paper will cover part of the picture, making it inconvenient to observe, compare, and adjust the picture.

[0004] Another method is to put a transparent plastic sheet under the painting hand to cover the picture, so that the picture can be seen through the sheet, which is convenient for the painter to compare and observe and adjust the picture. However, it also needs to be used when the drawing board is flat, and the smooth plastic sheet is very easy to slip, so it needs to be specially prepared.

[0005] Currently, there is a kind of sketching (anti-smearing) gloves on the market, which can cover the wrist, half of the palm and the bottom two fingers when drawing, leaving the thumb, index finger and middle finger exposed. This kind of gloves brings convenience to people who love cleanliness and don't want to wash their hands, but when drawing sketches, after holding the pen with the gloved hand, it has to be placed on the picture, which will still smear the picture, and at the same time, the sketching gloves will be stained by the picture. In this way, the sketching gloves must be cleaned regularly, otherwise the dirty gloves will stain the picture again, which is very troublesome. In order to solve the smearing problem, the painter wears sketching gloves and puts white paper or transparent plastic sheets under them during the painting process.

[0006] At present, there is a lack of a simple and convenient tool on the market that can be effectively used by painters at any angle of the drawing board to solve the problem of easy smearing of the picture during the sketch painting process. Summary of the invention

[0007] In order to overcome the lack of a simple and effective tool in the market in the prior art to solve the problem of easy smearing of the picture during sketching and painting, the utility model adopts the following technical solution to solve the technical problem: a cylindrical connecting tube opened downward is connected to the lower side of a side-opening annular finger ring, the edge of the opening has a circle of slightly inward-retracted connecting tube buckle edge, a connecting tube seam is opened on the side of the connecting tube, a joint ball is buckled into the connecting tube, and the joint ball is connected to the universal table downward through a connecting column, and a sleeve is provided on the rounded edge of the bottom surface of the universal table, the sleeve opens downward, and the edge of the opening has a circle of slightly inward-retracted sleeve buckle edge, a sleeve seam is opened on the side of the sleeve, and a smooth rolling ball is embedded in each sleeve.

[0008] The inner diameter of the finger ring is slightly smaller than the diameter of an average person's little finger, and the lateral opening is small, so that the finger ring has a certain degree of elasticity, and can be used to cover fingers of different thicknesses. The finger ring is integrated with the socket, and the inner diameter of the socket is slightly larger than the diameter of the joint ball, so that the joint ball can rotate smoothly in the socket. The socket seam and the side of the socket are continuous, and there are 2 to 4 of them, which act as expansion joints, so that the joint ball can be inserted into the socket through the socket seam, and is stuck by the buckle edge of the socket so as not to fall off. The joint ball is connected and integrated with the universal platform through the connecting column, so that the universal platform can rotate in multiple directions as the joint ball rotates, and the height of the connecting column is appropriate. The gimbal is minimized so as not to affect the operability, and the shape is preferably circular or rounded triangle. The inner diameter of the sleeve is slightly larger than the ball, so that the ball can rotate smoothly in the sleeve. The ball has a higher smoothness and is embedded in the sleeve through the sleeve seam as an expansion joint. It is caught by the slightly inward-retracted sleeve buckle edge and does not fall off. Part of the volume of the ball is exposed from the sleeve mouth to contact the drawing surface. The number of sleeve seams on the sleeve is 2 to 4, and the sleeve depth can enter part of the space of the gimbal, and the outer edges of the sleeve buckle edge and the sleeve buckle edge are moderately chamfered.

[0009] The utility model has a simple structure, is convenient for realizing functions, has a low manufacturing cost, and can be generally used in the process of drawing sketches. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] Now, embodiments of the present invention will be described with reference to the accompanying drawings:

[0027] Before drawing a sketch, the painter's hand 12 holds the painting pen 14 and wears the utility model on the little finger of the human hand 12 until it is firmly put on the innermost joint of the little finger. The universal platform 2 is located below the finger, and the bottom surface generally faces the sketch screen 13. When drawing a sketch, the human hand 12 is placed on the sketch screen 13. The universal platform 2 will contact the sketch screen 13 and adjust its direction as the rolling ball 11 contacts the sketch screen 13, so that it is stably placed on the sketch screen 13, which is convenient for the human hand 12 to hold the painting pen 14 and draw steadily. When the human hand 12 moves, rotates or leaves and is placed back on the sketch screen 13, the universal platform 2 will randomly adjust its direction and will always be placed flat on the sketch screen 13. Since the rolling ball 11 is a sphere with a smooth surface and rotates randomly, it can contact the sketch screen 13 in a minimum range in a rolling manner, thereby preventing the human hand 12 from smearing the sketch screen 13 to a minimum extent during the painting process.
