TECHNICAL FIELD
[0001] The utility model relates to a multi-head needle tube pen, in particular to a multi-head needle tube pen for staff drawing. BACKGROUND
[0002] In the field of music, staff is an important tool for recording music notes, rhythm and other information. Whether it is music teaching, music creation or music printing, the drawing of staff is indispensable. The traditional staff drawing method has many drawbacks, which seriously affects the efficiency and quality of drawing.
[0003] In the early stage, staff drawing mainly relies on manual methods, and the drawing personnel uses a ruler and a pencil to draw lines one by one. This method not only is extremely slow, but also is difficult to guarantee the parallelism of lines and the uniformity of spacing. Even experienced drawing personnel need to spend a lot of time and effort to ensure the accuracy of the staff, and any slight mistake will cause problems such as line inclination and inconsistent spacing, affecting the overall aesthetics and readability of the music score. Moreover, once a drawing error occurs, it is very troublesome to modify, and the entire music score may need to be redrawn.
[0004] With the development of technology, some drawing tools have been applied to staff drawing, such as ordinary multi-tip drawing pens. These tools have improved the drawing efficiency to some extent, but still have great limitations. The tip spacing of ordinary multi-tip drawing pens is usually fixed and cannot be flexibly adjusted according to different needs. However, in the actual music creation and teaching process, different music works and different teaching scenarios may require different specifications of staff, such as larger spacing staff suitable for beginners to identify notes, and smaller spacing staff that can record more music information in limited paper space. The fixed spacing multi-tip drawing pen cannot meet the diversified needs, which greatly limits its application range. UTILITY MODEL CONTENT

[0024] Sliding column 6 is slidably connected in the inside of sliding slot 5, one end of sliding column 6 is fixed with L-shaped block 7, and the horizontal plate of L-shaped block 7 is fixedly connected with pen refill 2, and the force of lifting plate 4 moving downwards to sliding column 6 is greater than the horizontal moving resistance of L-shaped block 7.
[0025] Shell 1: the external structure of pen, provides overall support and protection, and the internal space is used to accommodate other components.
[0026] Pen refill 2: a plurality of pen refills are installed at the bottom of the inside of shell 1 and arranged on the same straight line, and are used to draw staff lines.
[0027] Push-pull piece 3: an electric push rod is used, and is installed at the top wall of the inside of shell 1, and is used to control the lifting of lifting plate 4.
[0028] Lifting plate 4: located in the inner cavity of shell 1, can move up and down;The sliding slot 5 is formed on the plate, and the middle sliding slot is vertical, and the both sides of the sliding slot are inclined, and are used to guide the movement of sliding column 6.
[0029] Sliding slot 5: cooperate with sliding column 6, control the moving track of sliding column 6, the angle between both sides of sliding slot and horizontal plane is 30-45 °.
[0030] Sliding column 6: sliding in sliding slot 5, one end is fixedly connected with L-shaped block 7, and the power of lifting plate 4 is transmitted.
[0031] L-shaped block 7: the horizontal plate is fixed with pen refill 2, and the middle part has guide hole 9, which cooperates with guide column 8 to ensure smooth movement.
[0032] Guide column 8: fixed in the inner wall of the shell 1, matched with the guide hole 9 of the L-shaped block 7, plays a guiding role.
[0033] Bottom plate 10: located at the bottom end of the shell 1, a recess 11 is opened at the position corresponding to the pen core 2, used for accommodating the pen core 2.
[0034] Working principle: when the multi-head pen tube pen is used to draw the staff, first start the electric push rod installed on the inner side top wall of the shell 1, that is, the push-pull piece 3. The push-pull piece 3 is the power source for the operation of the whole device, and after being turned on, it will generate a linear thrust to push the lifting plate 4 connected thereto to move vertically downward in the inner cavity of the shell 1.
[0035] The lifting plate 4 is provided with a unique layout of the sliding groove 5, the middle part of the sliding groove is in the vertical direction, and the sliding grooves on both sides are intersected with the horizontal plane at an inclination angle of 30-45°. In the process of the downward movement of the lifting plate 4, the inclined sliding groove 5 interacts with the sliding column 6 sliding therein; due to the inclination of the sliding groove 5, an oblique downward force is applied to the sliding column 6, which can be decomposed into vertical downward and horizontal directional components according to the principle of force decomposition; and because the force given to the sliding column 6 by the downward movement of the lifting plate 4 is greater than the horizontal movement resistance of the L-shaped block 7, the sliding column 6 will generate displacement in the horizontal direction along the track set by the sliding groove 5. At the same time, since one end of the sliding column 6 is fixedly connected with the L-shaped block 7, the displacement will be transmitted to the L-shaped block 7, driving the L-shaped block 7 to move synchronously in the horizontal direction.
[0036] The horizontal plate of the L-shaped block 7 is fixed together with the pen core 2, so the horizontal movement of the L-shaped block 7 directly drives the pen core 2 to move synchronously. With the continuous downward movement of the lifting plate 4, the L-shaped block 7 drives the pen core 2 to move horizontally continuously, changing the distance between the pen cores 2; when the lifting plate 4 moves to the bottom end, the outermost pen core 2 is located at the end of the recess 11, and at this time the interval distance between the pen cores 2 reaches the maximum state. In this process, the user can accurately adjust the distance between the pen cores 2 by controlling the degree of descent of the lifting plate 4 according to the actual needs of drawing different specifications of staff, so as to realize the adaptation to various staff drawing scenes, greatly enhancing the applicability of the product.
[0037] Beneficial effect: a plurality of parallel lines can be drawn at one time, which significantly improves the efficiency of drawing staff and changes the tedious mode of traditional line-by-line drawing.
[0038] The user can accurately adjust the distance between the pen cores by controlling the degree of descent of the lifting plate according to the actual needs of drawing different specifications of staff, adapt to various drawing scenes, and have strong applicability.
[0039] The L-shaped block cooperates with the guide column to ensure smooth movement; the cooperation of various components ensures stable operation of the device, reduces shaking and deviation in the drawing process.
[0040] Adopt electric push rod as power source, one key start can realize pencil core distance adjustment, simple operation, reduce the operation difficulty and time cost of user.
[0041] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application have been described in detail, for those skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application, shall be included within the scope of the present application.
