Abstract

The utility model relates to a paste-glue gun structure without paste dripping, which has the main structure that a push rod is inserted into a gun body after passing through a push plate in a gun headstock, a thrust spring and a guide sleeve, the end of the push rod is combined with a push disc, and the gun headstock beside a gun grip is pivoted with a trigger which can push the push plate to move the push rod forwards and squeeze a paste can to extrude paste glue outwards. Because the push rod is moved forwards only by a push plate and forms a free state after finishing the action without any clamping devices, the paste can receive moderate backing buffer fed back by the push rod when excessive pressure is formed so as not be extruded of excessive paste glue; a backbone of the gun body is provided with a small pin which can be used for penetrating and unchoking the paste can when the glue at an opening of the paste can is solidified and hardened.

Description

Paste glue gun structure without dropping paste

The utility model relates to the paste glue gun structure of a kind of paste glue gun, particularly a kind of without dropping paste.

By general paste glue gun structure, the owner will pass a push rod 2 and penetrates in the body of a gun 3 in the rifle headstock 1 of the body of a gun one end as shown in Figure 1, wear a push pedal 4 on the rear wall 11 of rifle headstock 1 and the push rod 2 between the barral of a gun rear wall 31, then wear a spring 5 between push pedal 4 and the barral of a gun rear wall 31, then wear the card that a slice can reverse after the rear wall 11 of rifle headstock 1 and end plate 6, card ends between the rear wall 11 of plate 6 and rifle headstock and wears a spring 7, and a trigger 8 is pivoted in the rifle headstock 1 under the push rod 2.

As shown in Figure 2, the owner that advances of push rod 2 will pull push pedal 4 with cocking 8, and push pedal 4 promotes push rod 2 again advances, and the push rod 2 that advances need have a card to end just unlikely returning of power, advances and can continue maintenance when cocking once again; Card end plate 6 be subjected to pushing away of spring 7 pull with the push rod 2 angle θ that staggers, just can block push rod 2, prevent that it from retreating; When push rod 2 is shifted the terminal point of barral of a gun onto, then need press card and end plate 6 with thumb, the angle θ that staggers is disappeared, card ends strength and disappears, and the side must retract push rod 2.

Aforesaid paste glue gun structure, Yin Qika ends the effect of plate 6, make the action form that formation only advanced not move back when push rod 2 advanced pulled by pushing away of push pedal 4, no doubt it can be finished to beat and stick with paste action, but therefore make beating of push rod 2 stick with paste the space that loses buffering between action and paste jar, and stick with paste jar inside often because of a physical property own, the unavoidable pressure that can form a feedback when pressurized, when this pressure does not have the space of buffering to digest, just the paste glue that can extrude a little again alleviates pressure, and forms the unnecessary waste of sticking with paste glue.

Main purpose of the present utility model ties up to the deficiency in overcoming above-mentioned technology, a kind of without dropping paste paste glue gun structure is provided, its push rod is only stirred with a push jack to advance, after finishing, forward motion just is free state without any clamping device, stick with paste the buffering of stepping back that to accept its feedback appropriateness when jar has excess pressure to form thereby make, and unlikelyly extrude excessive paste glue.

Another purpose of the present utility model ties up in a kind of without dropping paste paste glue gun structure is provided, and device has a little pin on its body of a gun, can be used to penetrate the convenient means of mediation when sticking with paste the viscose glue setting and hardening of glue jar opening.

Technical solutions of the utility model are:

After mainly body of a gun structure being simplified, the overall structure that the whole body of a gun is extended to the rifle handle is all one-body molded with fibrous plastic, being one extends two body of a gun backbones in the rifle headstock and receives a ring to end, the downside one of rifle headstock extends into a rifle handle, the key stage casing of two body of a guies extends a C shape by ring to a side, pass a push rod during combination in the rifle headstock of the paste glue gun body of a gun and penetrate in the body of a gun, this push rod passes a slice push pedal in the rifle headstock, one push away pull spring and one the guiding sleeve after, penetrate the interior push rod end of the body of a gun in conjunction with a push-plate, and the trigger that is pivoted on the other rifle headstock of rifle handle, but pushing tow push jack and will dial before the push rod and paste jar in the extruding body of a gun is outwards extruded paste glue; And key little pin of device of going up of the body of a gun can be used for penetrating mediation when sticking with paste the viscose glue setting and hardening of glue jar opening.

Because push rod of the present utility model is only stirred with a push jack and advanced, and just is free state after forward motion is finished, without any clamping and drawing device, thereby sticking with paste the buffering of stepping back that to accept its feedback appropriateness when jar has excess pressure to form, and unlikelyly extruding excessive paste glue.The dredging device that the utility model is set---a little pin on the body of a gun when sticking with paste the viscose glue setting and hardening of glue jar opening, can be used for penetrating mediation expediently.

Fig. 1 is the combination section of paste glue gun in the known technology;

Fig. 2 is the action diagram that the push rod of paste glue gun is got stick in the known technology;

Fig. 3 is the action diagram that the push rod of paste glue gun retracts in the known technology;

Fig. 4 is a stereogram of the present utility model;

Fig. 5 is side-looking planar gesture figure of the present utility model;

Fig. 6 is that push rod of the present utility model retracts action diagram.

The utility model will be further described below in conjunction with accompanying drawing and embodiment.

As shown in Figure 4, after the utility model owner will be simplified body of a gun structure, the overall structure that the whole body of a gun 10 is extended to rifle handle 11 is all one-body molded with fibrous plastic, be one in two body of a gun backbones 13 of rifle headstock 12 extensions, receive a ring 14 to end, and the stage casing that the downside one of rifle headstock 12 extends into a rifle handle 11, two body of a gun backbones 13 extends a C shape by ring 15 to a side.

The owner will pass a push rod 20 and penetrates in the body of a gun 10 during combination in the rifle headstock 12 of the paste glue gun body of a gun 10, a slice push pedal 30, one that this push rod 20 passes in the rifle headstock 12 pushes away pull a spring 40 and a guiding sleeve 50, penetrate push rod 20 ends in the body of a gun 10 in conjunction with a circular push-plate 21, being pivoted one on the other rifle headstock 12 of rifle handle 11 also is the integrated trigger 60 of fibrous plastic, and on its body of a gun on key 13 device a little pin is arranged.

As shown in Figure 5, but cocking 60 just this push pedal 30 of pushing tow push rod 20 is dialled forward, and then the paste jars in the extruding body of a gun 10 are extruded paste glue.And as shown in Figure 6, as long as stick with paste glue and squeeze and catch push rod 20 head ends to pull back when finishing when one bottle, the paste glue jar that uses up is renewed, can construct again; And little pin 70 of device on its body of a gun can be pulled up it when sticking with paste the viscose glue setting and hardening of glue jar opening, is used for penetrating mediation, the carrying out of convenient construction.
