Description

Technical Field

[0001] This utility model relates to the field of stationery products, and in particular to a puncture-resistant stationery nail. Background Technology

[0002] Pencil pins are a common office stationery item. In schools, they are frequently used to secure posters and decorate classrooms. They are convenient and frequently used. However, due to the sharp pins, users (especially elementary school students) need to be extra careful to avoid being pricked. When stored in a box, the sharp pins often point in various directions, making it easy to prick one's hand when handling them. Furthermore, pins that have fallen on the floor can also prick one's foot; there have even been cases where students have nearly been injured by fallen pins. While pencil pins are convenient and can secure heavy decorations, making them a very useful tool, the exposed sharp points pose a certain danger when handling them.

[0003] In existing stationery staples, the spring structure is exposed. When several such staples are stored in a box, the spring covers, which are meant to protect the staples, become tangled together. Users need to manually separate these staples with springs, which is inconvenient. Even during separation, there is still a possibility of being accidentally pricked by the staple tip. When securing certain filamentous decorations, the exposed springs can become entangled with the decorations, making them difficult to use. A safe and puncture-proof stationery staple would provide greater peace of mind and convenience. Therefore, there is a need to design a puncture-proof stationery staple. Utility Model Content

[0028] Please refer toFigure 1 And Figure 2 The utility model provides a kind of prevent pricking stationery nail, comprising: body, spring 3, inner protective cover 4 and outer protective cover 5.Body includes needle cap 1 and nail needle 2, needle cap 1 inside is hollow structure, and nail needle 2 is fixedly arranged in the inside center of needle cap 1.The one end of spring 3 is connected needle cap 1, and is set in the periphery of nail needle 2.Outer protective cover 5 is hollow structure, and outer protective cover first end 51 and needle cap 1 are fixedly connected, and outer protective cover second end 52 and inner protective cover first end 41 are connected with interference fit, and inner protective cover 4 can move in the inside of outer protective cover 5.

[0029] In the stationery nail of the utility model, spring 3 is installed in the inner cavity of inner protective cover 4, and the first end of inner protective cover 4 is against spring 3, and inner protective cover 4 can move in the inside of outer protective cover 5.The one end of spring 3 is connected on the inner end wall of needle cap 1, and the other end of spring 3 is connected on inner protective cover 4 and is the one end close to the inner end wall of needle cap 1.Inner protective cover 4 is divided into first part and second part, the first part is located at the one end of the second part and is arranged away from needle cap 1, and the inner hole of the first part is for nail needle 2 to pass through, wherein the diameter of the inner hole is only for nail needle 2 to pass through.The one end of spring 3 away from needle cap 1 is abutted on the side wall of the second part, and in the natural state of spring 3, the other end of spring 3 is accommodated in the inner hole 432 of the second part of inner protective cover.

[0030] Example one, please refer to Figures 1 to 3 The inner protective cover 4 of stationery nail is cylindrical, and there is an inner hole 43 in the center as a passage for needle nail 2 to pass through, for hiding sharp nail needle 2.When not in use, nail needle 2 is in protective cover.The center of outer protective cover 5 is hollow, and inner protective cover 4 can move in the middle.Needle cap 1 top is fixed with spring 3 and nail needle 2.The end of inner protective cover first end 41 is provided with a cover plate for abutting against spring 3, and the cover plate is provided with a hole (not shown) for needle nail 2 to pass through.Needle cap 1 nail end is designed as a round head style, which can effectively avoid the situation that stationery nail falls on the ground, and sharp nail tip points upward and mistakenly pricks the foot of a person.When in use, the middle part of outer protective cover 5 is pinched by fingers and pressed into wall body, at this time, spring 3 is in compressed state (see Figure 3 ), so that inner protective cover 4 moves to outer protective cover 5 until inner protective cover 4 is completely located in outer protective cover 5, and outer protective cover second end 52 and inner protective cover second end 42 are flush, at this time, nail needle 2 exposes inner protective cover 4 to the maximum extent.Stationery nail is I-shaped, which can limit fingers and help force when nailing and pulling out stationery nail.

[0031] Example two, please refer to Figure 4, the inner hole 43 inside the inner protective cover 4 can only pass the nail needle 2, and the first end 41 of the inner protective cover is not provided with an end plate and can resist the spring 3.

[0032] Embodiment three, please refer to Figure 5 , the inner protective cover 4 is divided into a first part and a second part, and the inner hole 431 of the first part is used for passing the nail needle 2. In the natural state of the spring 3, one end of the spring 3 is fixed in the needle cap 1, and the other end is accommodated in the inner hole 432 of the second part of the inner protective cover 4, and the second end 52 of the outer protective cover is connected in an interference fit with the first end 41 of the inner protective cover. The first end 41 of the inner protective cover is provided with an inner limiting clasp 44, and the second end 52 of the outer protective cover is correspondingly provided with an outer limiting clasp 53, and the outer limiting clasp 53 is used for clamping into the inner limiting clasp 44, so as to prevent the inner protective cover 4 from falling off. It should be noted that the inner protective cover and the outer protective cover can also be connected in an interference fit by using other ways, and the shape is not limited to the cylindrical body shown in the figure, and can be any shape.

[0033] The anti-piercing stationery nail of the utility model is placed naturally, the nail needle 2 is hidden in the inner and outer protective covers, and hands are prevented from being pierced. When the stationery nail is used, the stationery nail needle 2 is pressed into the wall, the inner protective cover 4 is pushed into the outer protective cover 5 under the action of the wall, and at this time, the inner spring 3 of the stationery nail is compressed. When the stationery nail is pulled out, the inner protective cover 4 is pushed out of the outer protective cover 5 under the action of the spring force, the inner protective cover 4 is automatically reset and hides the nail needle 2. The spring force of the spring 3 needs to be suitable for the stationery nail. When the stationery nail is used, the spring 3 is in a compressed state, so that the nail needle 2 is exposed to the inner and outer protective covers to the maximum extent. When the stationery nail is not used, the spring 3 is kept in an expanded state, the needle cap 1 connected with the nail needle 2 is kept in a natural stretching state under the action of the spring force, and at this time, the nail needle 2 is retracted into the protective cover.

[0034] As an embodiment, the needle cap 1, the inner protective cover 4 and the outer protective cover 5 are printed by using 3D printing. The external style and internal structure diagram of the anti-piercing stationery nail in the static state and the use state are drawn by using computer drawing software and 3D modeling software, and then the physical object is printed. It should be noted that the physical object can also be made by using other ways.

[0035] In summary, the anti-piercing stationery nail is easy to fix articles, convenient and safe to use, and the situation that a user, especially a student, is mistakenly pierced by a stationery nail is avoided. Therefore, the utility model effectively overcomes various shortcomings in the prior art and has high industrial utilization value.

[0036] The above embodiments only exemplarily illustrate the principles and effects of the present application, and are not used to limit the present application. Any person skilled in the art can modify or change the above embodiments without departing from the spirit and scope of the present application. Therefore, all equivalent modifications or changes completed by those skilled in the art without departing from the spirit and technical thought disclosed by the present application should be covered by the claims of the present application.
