Abstract
The invention provides a pen cap not easily lost in use. The pen cap comprises a tube for holding the writing part of a penholder, one end of the tube is hermetically connected with the small end of a sucking disc, a support with an airflow through hole is fixed at the end of the tube, the airflow through hole is communicated with the cavity of the sucking disc and the cavity of the tube at the end, a piston in air-tight sliding connection with the inner wall of the tube is arranged in the tube, and the upper end of the piston is connected with the support through an elastic piece.
Description
Technical field
The present invention relates to a kind of cap for brush.
Background technology
In daily life, the cap for brush is often lost easily, causes penholder to use and deposits inconvenience.
Summary of the invention
The cap for brush that the technical problem that the present invention will solve is difficult for losing when providing a kind of the use.
In order to solve the problems of the technologies described above, technical scheme of the present invention is:
A kind of cap for brush; Comprise the cylindrical shell of admitting the penholder writing portion; One end and the sucker small end of cylindrical shell are tightly connected, and this cylindrical shell end is fixed with the bearing that has the air-flow through hole, and the air-flow through hole is communicated with the inner chamber of sucker inner chamber and this end cylindrical shell; Be provided with the piston that is slidingly connected with the cylinder inboard wall hermetic seal in the cylindrical shell, connect through elastic component between piston upper end and the bearing.
Said piston lower end is provided with the recess of admitting the penholder writing portion.
Said recess wall is taper type.
Said elastic component is cylindrically coiled spring or conical helical spring.
Said bearing is cross, and is one-body molded with cylindrical shell.
The present invention is tightly connected cylindrical shell and sucker small end, is provided with the piston that is slidingly connected with the cylinder inboard wall hermetic seal in the cylindrical shell, connects through elastic component between piston upper end and the bearing; Therefore, when plan using pen to write, appear for the first time sucker is affixed on the desktop; To pressing down penholder, piston moves down then, and sucker inner chamber and cylinder lumen gas are discharged; Cap for brush integral body is adsorbed on the desktop, takes out penholder, can use.When pen was finished using, penholder was exerted pressure to piston, and sucker separates with desktop, can preserve.
Description of drawings
Do further detailed explanation below in conjunction with the accompanying drawing specific embodiments of the invention:
Fig. 1 is structural representation of the present invention, has penholder.
Fig. 2 is Fig. 1 part-structure sketch map.
Fig. 3 is the vertical view of Fig. 1.
The sectional drawing of Fig. 4 piston.
Fig. 5 is the upward view of piston.
Among the figure: 1 penholder, 2 elastic components, 3 pistons, 4 suckers, 5 bearings.
The specific embodiment
Shown in Fig. 1～5; A kind of cap for brush comprises the cylindrical shell of admitting penholder 1 writing portion, and an end of cylindrical shell and sucker 4 small ends are tightly connected; This cylindrical shell end is fixed with the bearing 5 that has the air-flow through hole; The air-flow through hole is communicated with the inner chamber of sucker inner chamber and this end cylindrical shell, is provided with the piston 3 that is slidingly connected with the cylinder inboard wall hermetic seal in the cylindrical shell, connects through elastic component 2 between piston upper end and the bearing.
Said piston lower end is provided with the recess of admitting the penholder writing portion.
Said recess wall is taper type.
Said elastic component is cylindrically coiled spring or conical helical spring.
Said bearing is cross, and is one-body molded with cylindrical shell.
During use, penholder promotes piston and in cylindrical shell, slides, and sucker is close to desktop simultaneously, and the result releases the gas in the sucker.Atmospheric pressure acts on the surface of sucker, and the spring counter-force acts on the piston simultaneously.At this moment, penholder is extracted, cap for brush integral body promptly can be adsorbed on the desktop.Gas pressure intensity in the sucker is much smaller than atmospheric pressure at this moment, and piston can be towards the motion of penholder direction, up to reaching mechanical balance under the effect of spring.
When pen uses up, penholder is inserted in the cap for brush.Piston can move downward along cylindrical shell, and the gas of sucker and desktop sealing is discharged, and sucker separates with desktop.
