Abstract

The utility model relates to a pen with a pen cylinder and a pen holder which are combined tightly. The pen comprises the pen holder and the pen cylinder, and is characterized in that outer conical surfaces (1) and annular grooves (2) are formed in the head and tail of the pen holder respectively; annular elastic rings (3) are arranged in the two annular grooves (2) respectively; the pen cylinder is provided with an inner conical surface (4); the conical degrees of the outer conical surfaces (1) and the inner conical surface (4) are the same; the conical degrees of matched surfaces of the pen holder and the pen cylinder are the same, and the pen cylinder is sleeved on the pen holder tightly to be locked automatically; and after being compressed, the annular elastic rings have elasticity, so that the pen cylinder can be matched with the pen holder tightly.

Description

The compact pen of a kind of pen container and penholder

Technical field

The utility model relates to a kind of pen, is specifically related to a kind of pen container and cooperates closely pen with penholder.

Background technology

Existing pen has a shortcoming, namely pen container cooperates with penholder not tight, always gapped after pen container much is enclosed within on the penholder.Like this, when pen container was enclosed within the penholder head, pen container easily separated with penholder, and then pen container can not be protected nib; When pen container is enclosed within the penholder afterbody, feel when then writing that pen container is rocking, when writing, people also feel not too comfortable.The head that the pen container of a lot of pens is enclosed within penholder still has a tightness; But the afterbody that is enclosed within penholder is then very loose, if hand is taken pen container and penholder is placed towards the below, then penholder can fall down.

The utility model content

The technical problems to be solved in the utility model is that the pen container that overcomes existing pen cooperates untight shortcoming with penholder, provides a kind of pen container to cooperate closely pen with penholder.

The technical solution adopted in the utility model is: described a kind of pen container cooperates closely pen with penholder, comprise penholder and pen container, it is characterized in that: penholder head and penholder afterbody respectively have an outer conical surface and a cannelure, in described two cannelures an annular resilient collar are installed respectively; Pen container has internal conical surface.

The below proposes additional technical characterictic to above technical scheme:

1, the tapering of described two outer conical surface and an internal conical surface equates.

Beneficial effect: penholder equates with the tapering of the mating surface of pen container, and pen container is tightly placed on the penholder can self-locking; And have elastic force after annular resilient collar is compressed, make pen container tightr with cooperating of penholder.

Description of drawings

Fig. 1 is that a kind of pen container cooperates the closely front view of the penholder of pen with penholder;

Fig. 2 is the front view after the penholder among Fig. 1 is installed annular resilient collar;

Fig. 3 is that a kind of pen container cooperates the closely front view of the pen container of pen with penholder;

Fig. 4 is that a kind of pen container cooperates the closely front view of pen with penholder.

Among the figure: 1, outer conical surface; 2, cannelure; 3, annular resilient collar; 4, pen container.

The specific embodiment

The below cooperates Fig. 1 to Fig. 4, the utility model is described in further detail: a kind of pen container cooperates closely pen with penholder, comprise penholder and pen container, it is characterized in that: penholder head and penholder afterbody respectively have an outer conical surface 1 and a cannelure 2, in described two cannelures 2 annular resilient collar 3 are installed respectively; Pen container has internal conical surface 4.

The tapering of described two outer conical surface 1 and an internal conical surface 4 equates.

Annular resilient collar 3 is made by rubber, by glue in cannelure 2.The annular resilient collar on the right is to cut the technique of painting open among Fig. 2.

Claims

1. a pen container cooperates closely pen with penholder, comprise penholder and pen container, it is characterized in that: penholder head and penholder afterbody respectively have an outer conical surface (1) and a cannelure (2), and an annular resilient collar (3) respectively is installed in described two cannelures (2); Pen container has internal conical surface (4).

2. described a kind of pen container cooperates closely pen with penholder according to claim 1, it is characterized in that: the tapering of described two outer conical surface (1) and an internal conical surface (4) equates.
