Abstract

The utility model relates to an improved solid glue applicator, relating to office supplies, particularly a container for applying solid glue. The utility model is composed of a covering cap and a tube body which is sheathed up by an inner and an outer hollow tubes connected by a telescopic rod; one end of the telescopic rod is fixed to a closed end of the outer tube, the other end provided with a piston extends in the inner tube. The solid glue taking the piston as a base is formed in the inner tube body. The utility model omits rotation with the telescopic way of sending the glue out. The glue can be automatically sent out via the active force of a user in applying process to realize continuous application and convenient operation. The glue can not be wasted in the use process, so the utility model is adapted for various crowds.

Description

A kind of improved solid glue applicator

The utility model relates to a kind of office appliance, refers to a kind of appearance tool that is used to smear solid glue especially.

Popular solid glue applicator mostly is revolving greatly on the market, hollow cylinder one end of its built-in glue is the block mouth, be the discharging opening of solid glue simultaneously, other end socket one rotatable base, base central authorities are equipped with a screw rod and insert in the interior column solid glue of hollow cylinder, screw rod and column solid glue are the screw thread socket, during use, only need pull up block, rotating base, solid glue just can be placed outside the discharging opening by back-out, smears with this.This solid glue applicator uses more convenient, but also have the following disadvantages: one, automatically plastic emitting in the use, must artificially rotate the base that has screw rod, make solid glue expose barrel discharge hole, need rotation once more after exposed portions serve has been coated with, in for a long time continuous use, must spin coating be coated with, be coated with and revolve, indispensable rotary manipulation has influenced the continuous work that smears; Its two, expose the length of the solid glue of discharging opening and be difficult for to grasp, screws out a little lessly, scribble effect is poor, screws out morely, glue ruptures easily when smearing, and particularly for underage child, is difficult to especially operate.

The utility model is just in order to overcome above-mentioned deficiency, provides a kind of and exempts to rotate, plastic emitting automatically, need not to adjust the portable solid glue applicator of plastic emitting length.

Improvements of the present utility model are to change rotary plastic emitting into telescopic automatic plastic emitting.Specifically, a kind of improved solid glue applicator, form by block and stack shell, it is characterized in that stack shell is connect by the two inside and outside jacket casings that are hollow form forms, described inside and outside tube is connected by an expansion link, this expansion link one end is fixed in the urceolus blind end, and the other end that has piston stretches into inner core, and solid glue is that base takes shape in the inner barrel with the piston.When product comes into operation, place the solid glue of inner barrel just to expose interior nozzle, the user only need hold stack shell (the finger contact must be arranged on urceolus), in the process of smearing, the glue of nozzle in progressively consuming, because the process of smearing is a force process, and be a process of exerting oneself downwards, urceolus is subjected to the effect of downward force, has also applied downward force for expansion link, and simultaneously interior nozzle places coated article spare surface, the thrust that made progress by its surface, inner core along expansion link/urceolus do the indentation campaign, inner core slowly, continuous indentation, solid glue automatic plastic emitting process in use just, and gel quantity just, nozzle in only exposing, strip glue does not have phenomenon of rupture, can not produce waste in the process of smearing yet.

Inner diameter of steel flue of the present utility model is slightly less than the urceolus diameter, the gum outlet end of inner core is equipped with a shirt rim, the design of this shirt rim, can make glue expose interior nozzle slightly a bit, and unlikely by chance fair with interior nozzle, influence scribble effect, this shirt rim also can make by spreading object surface and plastic emitting face slyness and contact simultaneously, be more suitable for smearing, the user does not have the sensation of scratching.

Expansion link one end of the present utility model is fixed in urceolus blind end central authorities, to keep equilibrium of forces.The fixed form of the two, also can directly be fixed for good certainly with engaging, and its structure shows as at urceolus blind end middle part and is equipped with the arc lug, and described lug inboard is provided with groove, and this groove engages with the expansion link round edge.The engaging mode can make things convenient for the production of this applicator, only needs expansion link is engaged with the lug groove in when assembling, just can realize fixedlying connected of expansion link and urceolus.

The utility model is put the hollow tube-shape that the expansion link plunger designs in the inner core becomes an end to seal, and described blind end is expansion link fixedly.This trunk-piston diameter is slightly less than inner diameter of steel flue, and during the solid glue moulding, the glue bottom is stuck in the piston barrel, and the expansion link of being more convenient for is slowly released glue the glue applied thrust.

The interior nozzle circumference place that the utility model connects expansion link is equipped with annular end face.When assembling this applicator, elder generation of the expansion link that will engage with urceolus inserts from the inner core discharging opening, the outlet of passing inner core annular end face central authorities, be fixed in the urceolus blind end, the hollow tube-shape piston of expansion link other end is kept somewhere in inner core, is subjected to the obstruction of annular end face, and piston can not skid off inner core.Be close to the situation compacted under solid glue of inner core annular end face at the piston closes end, under the prerequisite that guarantees maximum glue quantity, also can avoid liquid object to enter urceolus, cause wastage of material.

The utility model adopts flexible plastic emitting mode just, has exempted rotation, by the user in the process of smearing firmly, finish the automatic plastic emitting of glue, realize smearing continuously, operate simple and easyly, can not waste glue in the use yet, be suitable for various crowds' uses.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is A-A figure.

Further specify the utility model below in conjunction with embodiment.

Embodiment 1, a kind of solid glue applicator of forming by block (1) and stack shell (2), stack shell is socketed to form with an expansion link (5) by two inner core (3), the urceolus (4) that are hollow form, these expansion link (5) one ends are fixed in urceolus (4) blind end central authorities, the other end that has piston (6) stretches into inner core, and solid glue is that base takes shape in the inner barrel with piston (6).

Embodiment 2, a kind of solid glue applicator of forming by block (1) and stack shell (2), stack shell is socketed to form with an expansion link (5) by two inner core (3), the urceolus (4) that are hollow form, these expansion link (5) one ends are sticked in the groove of two lugs (7) inboard in the middle part of urceolus (4) blind end, the other end that has a trunk-piston (6) stretches into inner core and piston (6) is subjected to inner core annular end face (8) restriction, and solid glue is that base takes shape in the inner barrel with piston (6).

Embodiment 3, reference example 2, and inner core (3) gum outlet is provided with shirt rim (9).
