Description

Pen-shaped solid gum

Technical field

The utility model is related to office stationary field more particularly to a kind of solid gums.

Background technology

Solid gum can be used for being bonded various paper and paper products, be suitable for office worker, financial and accountancy personnel, file clerk, religion Teacher, student and related personnel use.Stretching structure inside existing solid gum is typically all that screw rod is injected in colloid, rotates spiral shell During bar colloid is driven to stretch out upwards, such solid gum is disposable products, and colloid is inconvenient after use to replace.

Utility model content

The utility model provides a kind of pen-shaped solid gum in view of the above problems, and simple in structure and colloid is replaceable, repeats The solid gum used.

The utility model solve problem above used in technical solution be：A kind of pen-shaped solid gum, it is characterised in that：Including Penholder, rotating body, screw rod, colloid and glue core, the penholder, rotating body are tubular structure, and penholder upper end opening is socketed in The lower part of rotating body, rotating body lower part circumferentially rotate along rotating body with penholder top and are connected, in the lower part of rotating body Wall is equipped with screw thread, and the colloid is located at the top in rotating body, and the screw rod is located in penholder, and under screw rod and rotating body The threaded engagement of portion's inner wall, the upper end of screw rod are located in rotating body, and the upper end of screw rod is connected by the glue core with colloid, spiral shell The lower end of bar is equipped with circular limited block, and the outer circumferential surface of circular limited block is equipped at least one groove, the axis of groove and screw rod Axis is parallel, is equipped on the inner wall of penholder and is slidably connected with the one-to-one convex ribs of groove, convex ribs with groove along its length.

After more than structure, compared with prior art, the utility model is in turn rotating body, screw rod cooperation rotation Body rotates, and because the convex ribs of penholder play the groove of screw rod position-limiting action, screw rod can not rotate in a circumferential direction, and can only make to move down Dynamic, screw rod moves up and down the movement for promoting glue core and colloid, and colloid after use, can be installed to rotating body with new colloid It is interior.The utility model is simple in structure, easy to use, and colloid is replaceable after use, economizes on resources, and avoids meaningless waste.

Preferably, the outer wall of the rotating body lower part is equipped with annular indent, the corresponding position of the penholder inner wall Be equipped with annular protrusion, after so setting, annular indent and annular protrusion mutually axially /V, be conducive to rotating body lower part and Penholder top circumferentially rotates.

Preferably, the glue core upper surface be equipped with the first indent, glue core lower face be equipped with the second indent, glue core it is transversal Face is H fonts, and the lower end of the colloid is located in the first indent, and the upper end of the screw rod is connected in the second indent.Glue core rises To the protective effect to colloid, screw rod is avoided to be directly connected to colloid and destroy colloid, the first indent holds colloid and second Indent covers screw rod upper end, and radial direction position-limiting action is played to colloid and screw rod, avoids colloid and the screw rod sideslip when moving up and down.

Preferably, the rotating body lower end is set there are two symmetrical notch, the notch of rotating body forms sliding tooth and protects Shield when being screwed into top or bottom, avoids screw rod from continuing rotation ejection rotating body on earth.

Preferably, it further includes the cap for brush, the cap for brush is socketed in penholder top, and the penholder external wall of upper portion is equipped with step Face, penholder outer diameter more than step surface are less than the penholder outer diameter below step surface；Penholder below the step surface Outer wall is equipped with the 3rd indent, and the corresponding position of cap for brush inner wall is equipped with protrusion corresponding with the 3rd indent.After so setting, pen Front resilient portion of the cap for brush because of material in itself can strut when cap sleeve living penholder at step surface, and protrusion coordinates with the 3rd indent, The sealing structure air-tightness of the cap for brush and penholder is high.

Preferably, the cap for brush outer wall is equipped with pen clip, the design of pen clip makes solid gum reach the purpose easy to carry taken.
