Description

Technical Field

[0001] This utility model relates to the field of stationery-related technology, and in particular to a rotating children's oil pastel. Background Technology

[0002] Oil pastels are oil-based colored paints characterized by their smooth, delicate texture, excellent spreadability, superior layering and mixing properties, and vibrant colors. The coating has a certain thickness and exhibits strong adhesion and coverage on paper, providing a textured finish that fully showcases the effects of oil painting and meets the needs of various painting techniques.

[0003] Most existing oil pastels are straight-handled, meaning they are picked up directly for drawing when in use and stored in a box when not in use. When not in use, the exposed tip of the oil pastel makes it easy to accidentally deface the surrounding environment, resulting in poor usability.

[0004] To avoid exposing the tip of the oil pastel, the structure of the oil pastel has been improved. Utility Model Content

[0005] This invention aims to overcome the shortcomings of existing technologies, such as exposed pen tips that easily cause mis-painting on the surrounding environment and poor usability. It provides a rotary children's oil pastel with a retractable pen tip to prevent mis-painting and improve usability.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a rotating children's oil pastel, comprising:

[0007] The outer tube has a spiral guide groove on its inner wall;

[0008] The inner tube is sleeved with the outer tube, and the inner tube has a guide groove on its side wall;

[0009] A slider is placed inside an inner tube. A rod core is installed on the top of the slider. A guide block is provided on the outer wall of the slider. The guide block passes through a guide groove and is embedded in a guide rail groove.

[0010] Tail block, which is rotatably sleeved with the outer tube and connected to the inner tube.

[0011] This oil pastel includes an outer tube, an inner tube, a slider, and a tail block. The outer tube serves as the grip for the oil pastel, and the inner tube is fitted inside the outer tube. The slider, containing the oil pastel tip, is located inside the inner tube. A guide groove, arranged spirally, is provided on the inner wall of the outer tube. A guide groove is provided on the inner tube, and a guide block is located on the outer side of the slider. This guide block slides within the guide groove, and its end is embedded in the guide groove. A tail block is located at the lower end of the outer tube. This tail block rotates with the outer tube and is connected to the inner tube. When the tail block rotates, the inner and outer tubes rotate relative to each other. Simultaneously, the slider inside the inner tube moves vertically along the guide groove under the guidance of the guide groove and guide rail groove, allowing the tip of the oil pastel to move in and out of the outer tube. This allows the tip of the oil pastel to be stored in the outer tube when not in use, preventing accidental application of the tip and improving the overall effect.

[0012] Preferably, the guide groove is a strip-shaped groove, arranged coaxially with the inner tube. Stop grooves are connected to the upper and lower ends of the guide groove, and these stop grooves are arranged radially with the inner tube. Specifically, the guide groove is a strip-shaped groove, vertically arranged, and coaxial with the inner tube. Stop grooves are provided at both the upper and lower ends of the guide groove, radially arranged with the inner tube. The guide block can enter the stop groove along the guide groove. When the guide block slides into the upper stop groove, the rod core stops extending outwards; when the guide block slides into the lower stop groove, the rod core stops retracting, completing the storage of the pen tip. This structure enables the extension and retraction of the rod core, thereby improving the usability.

[0013] Preferably, the top of the slider is provided with a mounting groove, and the inner wall of the mounting groove is provided with several retaining strips. The retaining strips are arranged coaxially with the mounting groove, and the rod core is engaged with the retaining strips. Specifically, the mounting groove at the top of the slider and the several retaining strips on the inner wall of the mounting groove are arranged vertically. The rod core is engaged in the mounting groove. The retaining strips improve the fixing and engaging effect of the rod core, ensuring the stability of the rod core when entering and exiting the outer tube, and improving the performance.

[0014] Preferably, the guide block includes a connecting rod and a guide wheel. The guide wheel is rotatably connected to the end of the connecting rod, the connecting rod is placed in a guide groove, and the guide wheel is placed in a guide rail groove. Specifically, the guide block includes a connecting rod and a guide wheel. The connecting rod is connected to the side wall of the slider and is arranged at an angle matching the guide rail groove. Simultaneously, the guide wheel is rotatably connected to the end of the connecting rod, causing relative rotation between the guide wheel and the connecting rod. The connecting rod, placed in the guide groove, can slide along the guide groove, while the guide wheel is embedded in the guide rail groove and can slide within it. This structure allows the slider to move axially within the inner tube through the relative rotation of the outer and inner tubes, thereby driving the pen tip to press tightly against the outer tube. When not in use, the pen tip retracts, preventing accidental application and improving usability.

[0015] Preferably, the lower inner wall of the guide rail groove is provided with several limiting grooves, and the guide wheel is fitted into the limiting grooves. Specifically, the several limiting grooves on the lower inner wall of the guide rail groove are evenly spaced. When the guide wheel slides along the guide rail groove, it contacts the upper inner wall of the guide rail groove, thus guiding the movement. When the rod core is adjusted outwards, the guide wheel is embedded in the limiting groove, ensuring that the rod core will not move during use, guaranteeing the stability of the rod core, and improving the performance.

[0016] Preferably, a locking block is provided at the bottom of the inner wall of the outer tube, and a locking groove is provided in the middle of the outer wall of the tail block. The locking block engages with the locking groove, and a spring is sleeved in the locking groove. The two ends of the spring contact the end face of the locking block and the inner wall of the locking groove, respectively. Specifically, the locking block at the bottom of the inner wall of the outer tube engages with the annular locking groove in the middle of the outer wall of the tail block. This structure allows for the rotational engagement of the outer tube and the tail block. Simultaneously, a spring is provided in the locking groove, which engages with the groove. The two ends of the spring contact the end face of the locking block and the inner wall of the locking groove, respectively. The spring force ensures a stable connection between the tail block and the outer tube. When the tail block is pressed down, the guide wheel contacts the upper inner wall of the guide rail groove, facilitating the rotation of the tail block to extend the adjustment rod. When the tail block adjustment is complete, the spring force pushes the tail block outward, allowing the guide wheel to be stably embedded in the limiting groove. This improves the stability of the rod during drawing, thus ensuring good performance.

[0017] Preferably, the end face of the locking block is provided with an annular positioning groove, and the inner wall of the lower end of the groove is provided with an annular positioning block, which is embedded in the positioning groove. Specifically, the positioning groove on the end face of the locking block is annular, and the positioning block on the inner wall of the lower end of the groove is embedded in the positioning groove. When the tail block is pressed down, the positioning block contacts the bottom surface of the positioning groove, ensuring stable contact between the guide wheel and the guide rail groove, thus guaranteeing stable guiding effect and improving its performance.

[0018] Preferably, the upper end of the outer tube is provided with a conical opening, the conical opening having an inner wall that contacts the rod core. The conical opening at the upper end of the outer tube has a conical outer contour and is internally a hollow tube, ensuring stable support for the extended rod core and guaranteeing good performance.

[0019] The beneficial effects of this utility model are as follows: axial movement of the slider inside the inner tube can be achieved by rotating the tail block, allowing the stick core to extend during use and retract into the outer tube when not in use, avoiding accidental application and thus improving the performance.
