Description

Technical Field

[0001] This utility model relates to an eyebrow pencil structure, and more particularly to a push-pull eyebrow pencil structure. Background Technology

[0002] Makeup is a way for modern women to express respect for themselves and others. There are many types of cosmetics, categorized by different areas of the face, such as eye makeup and lip makeup. In eye makeup, an eyebrow pencil is an important tool, used to outline and modify the shape of the eyebrows, making the eyes more expressive. Modern eyebrow pencils generally use a spiral retractable design or a pencil-like shape. However, spiral retractable eyebrow pencils usually require two hands to operate; while pencil-like pencils require sharpening, making them cumbersome to use. Summary of the Invention

[0003] This utility model provides a push-pull eyebrow pencil structure that is simple in structure, has few components, and is easy to operate; it solves the technical problem of inconvenient operation of existing eyebrow pencils.

[0004] The above-mentioned technical problem of this utility model is solved by the following technical solution: A push-pull eyebrow pencil structure includes a pencil barrel and a pencil handle. A pencil cap is fitted onto the pencil handle. The pencil barrel has a receiving cavity, and a push-pull structure is provided in the receiving cavity. The push-pull structure includes a toothed rack formed on the inner wall of the pencil barrel and a sliding groove formed on the pencil barrel. A push button is installed in the sliding groove. A toothed rod is provided below the push button. One end of the push rod is connected to the toothed rod. The end of the toothed rod is located on the toothed rack. An eyebrow pencil lead is installed at the other end of the push rod. The end of the push rod with the eyebrow pencil lead is placed inside the pencil handle and moves in and out of the pencil handle with the movement of the push button. The toothed rack is integrated into the inner wall of the pencil barrel, resulting in a simple structure with few components. The eyebrow pencil lead moves in and out of the pencil handle by the forward and backward movement of the push button. The forward and backward movement of the push button is achieved through the cooperation of the toothed rod and the toothed rack. The entire push-pull structure has few components, high integration, is easy to operate, and has low cost.

[0005] Preferably, the rack has continuous teeth, each tooth including a tooth trough and a tooth apex, with the slope of the front side of the tooth apex greater than the slope of the rear side. The tooth shape is designed to limit the movement of the rack. The relatively gentle rear side of the tooth apex allows the rack to move quickly forward, over the tooth apex, and advance the eyebrow pencil lead. The relatively steep front side of the tooth apex allows the rear side of the rack to abut against it after the rack has passed, preventing it from retracting and thus preventing the eyebrow pencil lead from shrinking back. To retract the lead, the user simply pushes backward, allowing the rack to pass the tooth apex and retract.

[0006] Preferably, the front side of the tooth peak is a sloped surface, which connects to the arc surface of the tooth peak, while the rear side of the tooth peak is a downward-concave arc surface. The sloped surface provides strong support, preventing the tooth bar from retracting. The connection between the sloped surface and the arc surface allows the tooth bar to pass over the tooth peak and retract when the push button is activated. The downward-concave arc surface makes the tooth bar move forward more smoothly, easily passing over the tooth peak.

[0007] Preferably, the bottom surface of the toothed bar corresponds to the tooth shape on the rack, with the front half of the bottom surface of the toothed bar being an arc-shaped surface and the rear half being an inclined surface. The arc-shaped design of the front of the toothed bar facilitates forward movement, and the arc surface reduces friction. The inclined surface of the rear half abuts against the front side of the tooth peak, locking the eyebrow pencil lead and preventing it from retracting.

[0008] Preferably, the push rod includes an eyebrow pencil lead mounting component and a push rod body. The eyebrow pencil lead mounting component is polygonal or irregularly shaped, and its cross-section has the same shape as the cross-section of the central through hole in the pencil barrel. The eyebrow pencil lead mounting component can be any shape other than circular, as long as it prevents relative rotation. The cooperation between the eyebrow pencil lead mounting component and the central through hole guides the eyebrow pencil lead, allowing it to smoothly enter and exit the pencil barrel.

[0009] Preferably, the push rod has a centering strip formed on its main body. The centering strip includes an upper centering strip and a lower centering strip, which are located in the same diameter plane and are both connected to the inner wall of the pen holder. This centering strip design prevents the push rod from wobbling during movement, improving operational stability.

[0010] Preferably, the push rod is provided with a rack mounting plate, and a through hole is opened on the rack mounting plate. The rack is transitionally fitted with the through hole, and there are two racks that are parallel to each other.

[0011] Therefore, the push-pull eyebrow pencil structure of this utility model has the following advantages: the entire push-pull structure consists of only a push rod, with the rack integrated into the pencil holder. The overall structure is very simple, with few parts, low cost, and easy operation, allowing for one-handed operation. Furthermore, the design of the teeth on the rack ensures that the eyebrow pencil lead will not retract after being pushed out. When retraction is needed, simply flicking the push button will retract the eyebrow pencil lead. Attached Figure Description

[0015] The technical solution of the utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0016] Example:

[0017] like Figure 1 and 2 As shown, a push-pull eyebrow pencil structure includes a cylindrical pencil holder 1, with a pencil barrel 2 threadedly connected to the holder 1. A rectangular through hole is formed in the center of the pencil barrel 2. A pencil cap 3 is fitted over the pencil barrel 2. An end cap 13 is located at the rear of the holder 1. When the end cap 13 mates with the holder 1, it forms a receiving cavity inside the holder. An integral toothed rack 15 is formed at the bottom of the receiving cavity. The toothed rack 15 has continuous teeth, such as... Figure 3 As shown, the tooth includes a tooth peak 17 and a tooth valley 16. The slope of the front side 18 of the tooth peak is greater than the slope of the rear side 19. The front side 18 of the tooth peak is a sloped surface, which connects to the convex arc surface of the tooth peak, while the rear side 19 of the tooth peak is a concave arc surface.

[0018] A push rod 14 is installed within the receiving cavity. The push rod 14 includes an integrally formed eyebrow pencil lead mounting component 5 and a push rod body 6. The eyebrow pencil lead mounting component 5 is rectangular, and an eyebrow pencil lead 4 is mounted on it. The cross-section of the eyebrow pencil lead mounting component 5 is the same as the cross-sectional shape of the central through hole of the pen barrel 2. The eyebrow pencil lead mounting component 5 passes through the central through hole of the pen barrel and can extend out of the through hole to draw eyebrows. A toothed rod mounting plate 9 is formed on the push rod body 6. Two through holes are opened in the center of the toothed rod mounting plate 9, and toothed rods 8 are fitted into the through holes. There are two toothed rods 8, which are parallel to each other. One end of the toothed rod 8 contacts the rack 15, and the other end of the toothed rod 8 is formed with an integral circular push button 7. A sliding groove 10 is opened on the pen barrel 1. The push button 7 is located above the sliding groove 10 of the pen barrel, and the toothed rod 14 passes through the sliding groove 10 and abuts against the rack 15. The front half 20 of the bottom surface of the toothed rod 8, where it connects to the rack 15, is an arc-shaped surface, while the rear half 21 of the bottom surface of the toothed rod is a sloped surface. The slope of the sloped surface is the same as the slope of the front side of the tooth peak, allowing the rear side of the toothed rod 8 to abut against the rack 15, effectively preventing the push rod body 6 from moving backward, thus preventing the eyebrow pencil lead from moving backward. A straightening strip is also integrally formed on the push rod body 6, including an upper straightening strip 11 and a lower straightening strip 12 located on the upper and lower sides of the push rod body. Only the upper straightening strip is formed on the front side of the toothed rod 8, while both upper and lower straightening strips are formed on the rear side of the toothed rod. The upper and lower straightening strips are located within the same diameter plane, and both upper and lower straightening strips are connected to the inner wall of the pencil holder, thereby preventing the push rod from wobbling during movement.

[0019] To use, push the push button forward. The push button is fixed to the push rod, thus moving the push rod forward. The eyebrow pencil lead mounting piece at the front of the push rod moves within the through hole in the pencil barrel, guiding the push rod. Because the toothed bar and rack have a rounded contact surface, it is very easy to push one or more teeth forward, pushing the eyebrow pencil lead out of the pencil barrel to the desired length. Stop pushing the push button. The inclined surface of the rear half of the toothed bar abuts against the inclined surface of the front half of the tooth peak, effectively preventing the push rod from retracting and thus preventing the eyebrow pencil lead from retracting into the pencil barrel. After use, manually push the push button backward again. Due to the upward force and the curved surface design of the wave peak, the toothed bar slides out of the inclined section into the tooth valley, thus retracting the eyebrow pencil lead back into the pencil barrel.

[0020] The specific embodiments described herein are merely illustrative of the concept of the invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
