Description

pen with sliding cap

technical field

The utility model relates to a pen, in particular to a pen with a sliding pen cover.

Background technique

At present, the structures of known ballpoint pens or signature pens, fountain pens, etc. are mainly composed of a pen holder and a pen cap. When in use, the barrel of a general ballpoint pen or signature pen is separated from the cap, and the user will choose to put the cap on the end of the barrel, or put the cap aside, because the cap is small, it is easy to cause the cap to be lost, and the pen loses the functionality of the cap. Protection, the nib is easily damaged and loses its original function.

In addition, when the cap of a general pen is placed on a loose or untightened nib or barrel, it is easy to cause the sealing plug at the end of the pen tip or pen barrel to be embedded in the cap, and the hand cannot be easily taken out, which may cause the entire pen to be unusable. cause great waste.

Detailed ways

Referring to Fig. 1 to Fig. 3, a pen with a sliding cap of the present utility model includes a pen holder 1 and a pen cap 2 cooperating with each other, and the pen cap 2 is mainly composed of a sleeve 2a, a hinged joint, The sleeve cover 2b at the free end of the sleeve 2a is composed of an elastic positioning buckle 2c arranged on the outer wall of the sleeve 2a, the sleeve cover 2b is provided with a positioning projection 2d compatible with the elastic positioning buckle 2c; the sleeve 2a is provided with a positioning structure 2e on the inner wall near the end of the tube cover 2b. When the pen cap 2 is set on the pen holder 1 around the pen core, the pen holder 1 corresponding to the positioning structure 2e is provided with a corresponding positioning structure 2e. The lower limit structure 3; the upper part of the pen holder 1 is provided with an upper limit structure 4 corresponding to the positioning structure 2e. The positioning structure 2e is a positioning convex ring or several positioning bosses arranged along the circumference of the sleeve 2a. In this embodiment, the positioning boss is selected as the positioning structure 2e.

Specifically, the pen holder 1 is composed of a pen holder 1a and a nib 1b screwed to the lower end of the pen holder 1a, the upper limit structure 4 is arranged at the upper proximal end of the pen holder 1a, and the lower stop structure 3 is arranged on the nib 1b. The lower limiting structure 3 described in this embodiment is composed of first upper protruding ring 3a and first lower protruding ring 3b arranged at intervals, the outer diameter of the first upper protruding ring 3a is smaller than the outer diameter of the first lower protruding ring 3b diameter; when the pen cap 2 is sleeved on the pen holder 1 on the periphery of the refill, the positioning boss is set between the first upper and lower convex rings 3a, 3b, and the first lower convex ring 3b is used to carry out the pen cap 2 The limit prevents it from protruding from the lower end of the pen holder 1. The upper limit structure 4 is composed of a second upper protruding ring 4a and a second lower protruding ring 4b arranged at intervals, the outer diameter of the second upper protruding ring 4a is greater than the outer diameter of the second lower protruding ring 4b; when the pen cap 2 When moving to the upper end of the pen holder 1, the positioning boss is clamped between the second upper and lower protruding rings 4a, 4b, and the second upper protruding ring 4a limits the position of the pen cap 2 to prevent it from coming out of the upper end of the pen holder 1 . Since the main bodies of the pen holder 1 and the pen cap 2 are both made of plastic and have a certain elastic deformation, the positioning boss can slide past the corresponding first upper convex ring 3a or second lower convex ring 4b and then get stuck.

Further, a hinge seat 2f is provided on the outer wall of the free end of the sleeve 2a, and an elastic book card 2g is provided on the hinge seat 2f along the axial direction of the sleeve 2a, which can be used to clamp thin objects, or The pen is clamped on other thin objects; the cylinder cover 2b is hinged on the hinge seat 2f, and the structure of the elastic positioning buckle seat 2c in this embodiment is also similar to the structure of the elastic book card 2g, except that the opening direction is different. When the cover 2b is opened, the elastic positioning buckle 2c is idle, and can be used as an elastic book card 2g at this time; meanwhile, a protective groove 2h for protecting the nib is provided inside the cover 2b.

When in use, when the pen is not in use, the pen cap 2 is fixed at the lower limit structure 3, and the cap 2b is fastened to the end of the sleeve 2a to protect the pen tip; when the pen is to be used, open the cap 2b , Push the whole pen cap 2 upwards forcefully, so that the positioning boss slides out from the lower limit structure 3, and snaps into the upper limit structure 4.

The above-mentioned embodiment is a preferred implementation mode of the present utility model, but the implementation mode of the present utility model is not limited by the above-mentioned embodiment, and any other changes, modifications, modifications, Substitution, combination, and simplification should all be equivalent replacement methods, and are all included in the protection scope of the present utility model.
