[0020] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0021] In the description of the present application, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.
[0022] It should also be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not require further definition and explanation in subsequent drawings.
[0023] The specific implementation of the utility model is described in detail below in conjunction with the accompanying drawings.
[0024] like Figures 1 to 5 As shown, a universal pencil cap for protecting pencils of different sizes comprises a cap body 1 with an elastic structure and a fixing sleeve 2.
[0025] The cap body 1 extends in the direction of the straight line L1, and is provided with a chamber 3 connected to the outside for accommodating the pencil tip therein. In order to allow the pencil cap to protect pencils of different sizes, a taper is set on the inner wall (inner diameter) of the chamber 3, and the tip of the taper is set in the direction of the straight line L1 (the bottom of the cone is located at the bottom of the cap body 1, and the tip of the cone is toward the top of the cap body 1).
[0026] like Figures 1 to 5 As shown, a circumferentially arranged and axially extending annular groove 5 is provided on the outer diameter of the cap body 1, and the top end of the fixed sleeve 2 is folded inward to form a fixed boss 6, and the fixed boss 6 cooperates with the annular groove 5 to enable the fixed sleeve 2 to perform axial reciprocating motion on the cap body 1. The inner wall of the fixed sleeve 2 is also tapered along the direction of the straight line L1, and the taper of the inner wall of the fixed sleeve 2 is equal to the taper of the inner wall of the chamber 3.
[0027] By setting the taper of the inner wall of the chamber 3 and the fixing sleeve 2, the pencil cap can be adapted to pencils of different sizes. The pencil cap has two states, namely, a thick pencil state in which the pencil is fixed by the inner wall of the fixing sleeve 2 and a thin pencil state in which the pencil is fixed by the inner wall of the chamber 3. The pencil cap can be switched between the thick pencil state and the thin pencil state by sliding the fixing sleeve 2.
[0028] Specifically, Figure 1 As shown, when the thin pencil is in use: the pencil tip is directly inserted into the chamber 3, and the pencil is clamped by the taper of the inner wall of the chamber 3. At this time, the fixing sleeve 2 can slide and rotate freely, and has a certain playability.
[0029] like Figure 2 As shown, the thick pencil is in use: since the diameter of the pencil is larger than the maximum taper diameter of the chamber 3, the pencil cannot be inserted into the chamber 3. By sliding the fixing sleeve 2, the pencil can be inserted into the fixing sleeve 2, and the thick pencil with a larger diameter can be fixed by the fixing sleeve 2. (The specific sliding position of the fixing sleeve 2 can be controlled according to the diameter of the thick pencil)
[0030] When the fixing boss 6 is located at the top of the annular groove 5, the fixing sleeve 2 also wraps the bottom of the cap body 1, and at this time, a reserved spacing 7 is provided between the bottom outer diameter of the cap body 1 and the bottom inner diameter of the fixing sleeve 2. By providing the reserved spacing 7, the fixing sleeve 2 can slide up and down on the cap body 1 better.
[0031] like Figure 3 to Figure 4 As shown, specifically, the cap body 1 includes a protective end 11 and a fixed end 12; the protective end 11 is in a frustum shape, which can better protect the pencil tip, so that the pencil tip is not easily broken when it falls to the ground and collides. The bottom surface of the frustum is integrally connected with the top surface of the fixed end 12, and the reserved spacing 7 is set between the bottom outer diameter of the fixed end 12 and the bottom inner diameter of the fixed sleeve 2.
[0032] like Figure 3 As shown, the top of the protection end portion 11 is provided with a through hole 9 connected to the chamber 3. The design of the through hole 9 can provide ventilation to the human body and ensure the condition of autonomous breathing when swallowing occurs.
[0033] like Figures 1 to 4 As shown, the cap body 1 can be made of a transparent or non-transparent elastic material, and at least one observation hole 8 is provided on the cap body 1, and the observation hole 8 is axially arranged in the middle of the cap body 1. Half of the observation hole 8 is located on the protection end 11, and the other half is located on the fixed end 12.
[0034] When the cap body 1 is made of transparent material, the fixing of the pencil can be observed through the cap body 1; and when the material is non-transparent, the fixing of the pencil can be observed through the observation hole 8. When the pencil cap is formed, the centering position of the pencil cap can be determined through the observation hole 8.
[0035] The above is a description of the embodiments of the utility model. Through the above description of the disclosed embodiments, professionals and technicians in the field can implement or use the utility model. Various modifications to these embodiments will be obvious to professionals and technicians in the field. The general principles defined in this article can be implemented in other embodiments without departing from the spirit or scope of the utility model. Therefore, the utility model will not be limited to these embodiments shown in this article, but will conform to the widest range consistent with the principles and novelties disclosed in this article.
