The cap for brush

Technical field

The utility model relates to a kind of parts, particularly a kind of cap for brush with movable pen clip.

Background technology

Pen clip of the prior art normally is fixed on the cap for brush and clamps by the elasticity that the pen clip material is had, owing to be subjected to the restriction of material property, therefore often fracture.

Invention constitutes

The purpose of this utility model is to overcome weak point of the prior art and the cap for brush that the movable not easy fracture of a kind of pen clip is provided.

The purpose of this utility model realizes by following approach.

The cap for brush, comprise cap body and pen clip, its structural feature is: cap body top has first vertical slot, a wherein sidewall of the first vertical slot groove width direction is a first side wall, and this first side wall is a kind of thin-walled, is separated with a kind of space between this thin-walled outside, the pen clip stiff end has a kind of olive shape boss, this olive shape boss is plugged in this first vertical slot, and the long limit of this olive shape is greater than the groove width of this first vertical slot, and a kind of vertical spacing device is between cap body and pen clip.

Like this, pen clip is plugged in first vertical slot of cap body by the boss of stiff end, because the long limit of olivary boss is greater than the groove width of first vertical slot, therefore, when rotating pen clip, the long limit of olive shape boss just contacts with the sidewall of first vertical slot, and, the sidewall of this first vertical slot is a kind of thin-walled, and is separated with a kind of space between the outside of this thin-walled, opens greater than the long limit of the olive shape boss of the first vertical slot width sidewall with this first vertical slot, simultaneously, the convergent force of open sidewall backward-acting again make pen clip tool clamping force, and the outside of the slyness of olive shape boss is easy to the rotation of pen clip on the olive shape boss.Vertical spacing device between cap body and pen clip is used to limit the position of pen clip vertical direction.

The purpose of this utility model can also realize by following approach.

Another sidewall of the groove width direction of relative distribution with the first side wall also is a kind of thin-walled.

Like this, the opposition of two side acts on the pen clip, makes pen clip have bigger clamping force.

Thin-walled is the unsettled suspention wall in a kind of lower end.

Such structure is to make that thin-walled is easier to be opened, thereby reduces the open resistance of pen clip.

The concrete structure of vertical spacing device has multiple choices, wherein a kind ofly can be: making on boss has a kind of centre bore concentric with the boss pivot, with a kind of bearing pin respectively with this centre bore and cap body on corresponding hole pin joint, thereby center of rotation that both can positive stop lug boss can be used as a kind of vertical spacing device again; And another kind can be: boss surface has the inclined-plane that a kind of its least significant end is positioned at the boss bottom face, first vertical slot upper end sealing and have the seam end, the boss upper surface can with this seam end clamping.

The least significant end of boss surface is positioned at the boss bottom face, it is a kind of inclined-plane that upwards increases gradually by the bottom, and the seam end of the first vertical slot upper end and boss clamping, the wedge effect of boss by the inclined-plane is pressed in the groove under the seam end and makes the first vertical slot upper end and the clamping of seam end, like this, pen clip is just fixing in the position of the vertical direction of the cap for brush.

The pen clip stiff end has a kind of inserted block, and the olive shape boss has two and lay respectively at the inserted block both sides, and cap body top has second vertical slot, this second vertical slot and the first vertical slot right-angled intersection, and the inserted block bottom can be contained in this second vertical slot.

Inserted block by the pen clip stiff end rigidly fixes olive shape boss and pen clip, make this two between the position interfix, and this inserted block is plugged in cap body second vertical slot, therefore, pen clip can't rotate around vertical axes, limited the rotation of the relative cap for brush of pen clip, and this second vertical slot intersects with first vertical slot, just in time met the setting of pen clip stiff end inserted block and lug boss position.

The second vertical slot two side is a kind of thin-walled, is separated with a kind of space between this thin-walled outside.

Like this, because thin-walled is convenient to open, boss snaps fits in the groove at seam end place more easily by its inclined-plane; Simultaneously, because of second vertical slot and first vertical slot intersect, the space in the thin-walled of second vertical slot outside helps the design and the manufacturing of the outer side clearance of the first side wall.

Boss shows form outward and can be specially: or be a kind of ellipse, or be a kind of water droplet shape, or be a kind of rhombus of sharp corner rounding.

Boss outward now form at all events plant form, all must be a kind of outer ring slyness, length and width are not isometric and boss that projection is arranged can either sidewall being opened by projection, be not obstructed because of the surface of slyness does not make to rotate again.

In sum, the utlity model has following advantage: the cap for brush, the cap body separates with pen clip, resilient force by the thin-walled in the cap body is on pen clip, not only has the characteristic that better elasticity clamps, and the subtended angle of pen clip has also enlarged, and has to use dexterous convenience and produce characteristics such as easy to assembly.
