Description

Propelling pencil

Technical field

The utility model relates to a kind of pencil, specifically is a kind of propelling pencil.

Background technology

Pencil is the stationery of using always, and common pencil is owing to need wrap up wooden holding rod at lead for retractable pencil, and this need consume a large amount of timber naturally, is unfavorable for the enforcement of energy-saving and emission-reduction, thereby country encourages to use propelling pencil energetically at present; This class has the propelling pencil of movement spring Telescopic mainly by the knot of pressing bar and runner at present Structure is controlled realization, and this structure is prone to the hair fastener phenomenon of beating, and causes propelling pencil temporarily can't use Or problem such as lead for retractable pencil fracture.

The utility model content

The purpose of this utility model is to provide a kind of propelling pencil, uses the movement relation of slide block and pen clip to replace original structure function of pressing bar and runner, and this kind structure function is more stable relatively, is not prone to the hair fastener phenomenon of beating, and promotes product quality.

For achieving the above object by the following technical solutions:

A kind of propelling pencil, comprise nib, cartridge assemblies and penholder, cartridge assemblies is placed in the penholder, nib is screwed in the front end of penholder, it is characterized in that: described cartridge assemblies comprises movement and is enclosed within the outer interior pipe of movement, the front end of interior pipe is connected with metal penpoint, is provided with the movement spring between the front end madial wall of the front portion of movement and interior pipe; Between interior pipe front portion and nib, also be provided with the spring spring, the rear end of movement is connected with the rubber seat, the rubber seat is with slide block assembly outward, slide block assembly also is with the pen clip assembly outward, and the pen clip assembly is connected the rear end of penholder, is provided with breach on the bar wall at penholder rear portion, the slide block of slide block assembly can pass and corresponding with the pen clip of pen clip assembly from this indentation, there, the inboard of pen clip is provided with projection, and Dui Ying slide block is provided with the groove that matches with it, and the rear end of rubber seat and slide block assembly is with presses cap.

The projection of described pen clip inboard is the triangle convex, and the groove on the described slide block is the triangle groove.

Be provided with salient point on the outer wall of described rubber seat, salient point is against on the front end face of pen clip assembly.

The front end of pipe is provided with retainer in described, and retainer is positioned at the bloom rear side of assembly of movement front end

In the front port of described metal penpoint, be provided with fixedly needle tubing, be provided with damping at fixing needle tubing rear portion.

The utility model adopts the movement relation of slide block and pen clip to replace original structure function of pressing bar and runner; This kind structure function is more stable relatively, is not prone to the hair fastener phenomenon of beating, and promotes product quality, For realizing that propelling pencil can stretch in the movement spring, can normally press the dual-use function that knockout is write again, carry Supplied a kind of new structure.

Shown in Fig. 1-6, a kind of propelling pencil, comprise nib 1, cartridge assemblies and penholder 2, cartridge assemblies is placed in the penholder 2, and nib 1 is screwed in the front end of penholder 2, and described cartridge assemblies comprises movement 31 and is enclosed within the outer interior pipe 32 of movement, the front end of interior pipe 32 is connected with metal penpoint 33, in the front port of metal penpoint 33, be provided with fixedly needle tubing 34, be provided with damping 37, between the front end madial wall of the front portion of movement 31 and interior pipe 32, be provided with movement spring 36 at fixing needle tubing 34 rear portions; Between interior pipe 32 front portions and nib 1, also be provided with spring spring 35, the active force of spring spring 35 is greater than movement spring 36, the front end of pipe 32 is provided with retainer 38 in described, retainer 38 is positioned at the bloom rear side of assembly 39 of movement 31 front ends, the rear end of movement 31 is connected with rubber seat 4, the rubber seat 4 outer slide block assemblies 5 that are with, the slide block assembly 5 outer pen clip assemblies 6 that also are with, pen clip assembly 6 is connected the rear end of penholder 2, on the bar wall at penholder 2 rear portions, be provided with breach 21, the slide block 51 of slide block assembly 5 can pass and corresponding with the pen clip 61 of pen clip assembly 6 from this breach 21, the inboard of pen clip 61 is provided with triangle convex 62, Dui Ying slide block 51 is provided with the triangle groove 52 that matches with it, on the outer wall of described rubber seat 4, be provided with salient point 41, this salient point 41 can pass on the front end face that slide block assembly 5 is against pen clip assembly 6, and the rear end of rubber seat 4 and slide block assembly 5 is with presses cap 7.

The course of work of the present utility model is such: press when pressing cap when finger, slide block is promoted forward immediately pins the slide position thus in pen clip triangle convex embeds its triangle groove; Meanwhile, slide block drives whole cartridge assemblies and moves forward, makes metal penpoint expose nib; Because the reach of slide block impels two salient points and the pen clip assembly end face on the rubber seat to isolate a segment distance, effect because of the movement little spring, move after metal is bloomed and be lockable, the lead for retractable pencil locking of being bloomed thus, the while metal is pressed cap and is also moved backward, isolate certain distance of pressing with slide block, this finishes metal penpoint to propelling pencil and exposes written action; Again since the power of spring spring greater than the power of movement movement spring, so when pressing metal with less power and press cap, metal is bloomed and opened normal knockout, this finishes the action of pressing knockout to propelling pencil; When pressing when pressing cap with bigger power, slide block is promoted forward, and pen clip triangle convex breaks away from slide block triangle groove, because the effect of big spring, slide block moves immediately up to being blocked the location by pen clip assembly end face backward, and whole cartridge assemblies also moves backward, in the metal penpoint indentation nib again; Meanwhile, the salient point on the rubber seat props up pen clip assembly end face again, and impelling blooms returns to open mode, and top cap and slide block fit again, and this is to finishing the action that returns to reset condition.
