Description

Glue gun

Technical field

Relevant with hardware apparatus, in particular to a kind of glue gun of the invention.

Background technology

In the constructing operations such as finishing, the semi-fluid glue of wound packages, which is extruded, needs a kind of glue gun, and it is general manual Manual operation, it is made up of spanner, gun rack, handle, push rod, spring, sleeve etc., in use, pulling spanner, reciprocating operation promotees back and forth Make glue of the push rod sinciput packing element cylinder bottom in the release cylinder as piston to lay coating；The packing element length of dress glue typically exists More than 25cm, so glue gun is used for accommodating the length sleeve of packing element also in more than 25cm, plus the gun rack length after sleeve again Plus the length of the push rod for sinciput, the glue rifle length in use is not less than half meter, and the instrument as singlehanded manual operation comes Say, such length is very inconvenient, carrying even usually, the single glue gun also length more than the 30cm, in order to construct And it is easy to carry for the sake of be sought after this conventional gluing instrument reducing volume.

The content of the invention

The purpose of the present invention is to provide a kind of new technical scheme of glass glue gun, and it can solve the problems, such as foregoing.

The content of technical solution of the present invention is as follows：It includes handle, spanner, gun rack, and the gun rack is rectangular box-like, gun rack Centre have the inflator with breather check valve of circle by upper and lower basket side fixing device, the piston rod on piston is from beating The right-hand member of inflator stretches out to the right to be flexibly connected by a pin rod with the upper end of spanner again, then concentric on the gas outlet of inflator left end The tracheae for being connected with an overcoat stretched out to the left and the colloid accordion of pull bar pipe, while returning apparatus has one at this gas outlet Outgassing nonreturn valve, vent valve；Set one to be provided with circular notch towards a left side in the left end of gun rack and be machined with externally threaded circular card Enclose, collar is divided into Internal and external cycle two parts by the circular notch on collar, and outer perimeter section is uniform in its circular end face towards a left side It is provided with multiple gap towards a left side；One nut for being machined with the internal thread to match with the external screw thread on collar is rotatably coupled to collar On, nut will process bunchy mouth shape at its end face inwall towards a left side；Piston reciprocating work inflator is promoted to start when pulling spanner When inflating, tracheae that overcoat telescopic lever will cross collar, nut stretches out to the left, and tracheae can shrink again when opening vent valve Return original state.

The beneficial effects of the invention are as follows：Its easy to operate volume simple in construction greatly reduces.

Brief description of the drawings：

Fig. 1 is the front assembling half sectional view of the design glue gun（Schematic device containing packing element）.

Fig. 2 is collar, the plan view of nut left side.

Fig. 3 is the overall front plan view of packing element device glue gun in place.

In each figure, 1 is gun rack, and 2 be spanner, and 3 be handle, and 4 be piston rod, and 5 be inflator, and 6 be collar, and 7 be nut, 8 For pull bar pipe, 9 be tracheae, and 10 be packing element, and 11 be outgassing nonreturn valve, and 12 be vent valve, and 13 be notch, and 14 be gap, 15 be into Gas check valve.

Embodiment：

Below in conjunction with the accompanying drawings to the design explanation for example.

As shown in Figure 1, Figure 2, Figure 3 shows, the glue gun of the design citing includes handle 3, spanner 2, gun rack 1, and the gun rack 1 is Rectangular box-like, the centre of gun rack has the inflator 5 with breather check valve 15 of circle by upper and lower basket side fixing device, living Piston rod 4 beyond the Great Wall stretches out to the right from the right-hand member of inflator to be flexibly connected by a pin rod with the upper end of spanner 2 again, when past back and forth Inflator will produce pressed gas when pulling spanner again, as shown in Figure 1；The concentric company on the gas outlet of the left end of inflator 5 The tracheae 9 that an overcoat stretched out to the left the colloid accordion of pull bar pipe 8 is connected to, while returning apparatus has one to go out at this gas outlet Gas check valve 11, a vent valve 12, the right-hand member of tracheae 9 are fitted on the inflator 5 that can produce pressed gas, and its tube wall is fold knot The elastomeric material that the telescopic resilience of structure is good is processed, and when no pressure is filled with, the pleated structure of its tube wall can shrink in most completely Short status, when there is appropriate pressed gas to be filled with pipe, the pleated structure of tube wall then can be partially opened or opened completely, entirely Body will be extended until the limit reaches most long status, be filled with a kind of telescopic pull bar pipe 8 in air pipe sleeve, pull bar pipe 8 is A kind of thin-wall high intensity pipe by more piece gradient-thickness is assembled by elastic card interlocking to be combined for the tubulose of an entirety Thing, such as the reception telescopic antenna that electronic product assembles, the matched both ends suit in tracheae in its both ends in place and is fixedly connected It is good, when tracheal strips are full of or drain pressure gas tracheae full extension or pull bar pipe also accompanies synchronous full extension when shrinking completely Or shrink, because pull bar caliber is immutable, the tracheae in it will be only towards axial direction in the pressure for the gas that is under pressure Extend to the left, the pressure of tracheae four will dissipate and weaken top to the left if the pull bar pipe as being not provided with overcoat is restrained tracheae Contribute, as shown in Figure 1, Figure 3；One is set to be provided with the notch 13 of circle towards a left side and be machined with externally threaded in the left end of gun rack 1 Collar 6 is divided into Internal and external cycle two parts, circle of the outer perimeter section at it towards a left side by circular collar 6, the circular notch on collar 6 Multiple gap 14 towards a left side are uniformly provided with end face；One is machined with the nut of the internal thread to match with the external screw thread on collar 7 are rotatably coupled on collar 6, and nut 7 will process bunchy mouth shape at its end face inwall towards a left side, as shown in Figure 1 and Figure 2, with spiral shell Female gradually screws, the outer perimeter section for the locking collar that the outer end of the beam mouth of nut will be increasingly tighter, and the width of notch is also It is less and less, it can thereby lock the bottom barrel for the packing element 10 for inserting notch；Piston reciprocating work is promoted to beat when pulling spanner 2 When inflator 5 starts to inflate, the outgassing nonreturn valve 11 of device can cooperate at the breather check valve 15 and gas outlet on inflator Pressed gas and the charged pressure gas into the pipe of tracheae 9 can be produced by ensuring inflator, overcoat the tracheae 9 of pull bar pipe 8 because Being filled with for pressed gas will extend across collar 6, nut 7 to the left until most strong point, open vent valve 12 and bleed off pressed gas When tracheae 9 again can shrink back most short original state；When specifically used, nut 7 is laid down first, and the barrel of the bottom of packing element 10 is sticked into groove In mouthfuls 13, then bottom of the tightening nut until pinning packing element, then pull spanner and start to inflate, as it was previously stated, tracheae will be to The first from left directly extends, and the movable cylinder bottom that the left end of tracheae will withstand packing element 10 ejects sizing material in cylinder to the left as piston, such as Shown in Fig. 3, reclaimed with pressed gas tracheae is bled off later, remove packing element and complete one action.Due to using the structure of the above, Glue gun eliminates the sleeve and push rod that original volume increases so that the length reduction of this common tool of glue gun to original 1/ 2 to 1/3, facilitate carrying and use, and meanwhile it is also laborsaving many, it is the useful improvement of this common tool of glue gun.
