Description

Dropless glue gun

The utility model belongs to manual plastic squeeze instrument, relates in particular to a kind of dropless glue gun.

At present, on the market in the common glue spraying gun, what be subjected to that people favor surely belongs to the powerful manually glue spraying gun ＂ of the ＂ high viscosity type of now having patented, its Granted publication number is CN2400190Y, in this body of a gun push rod is housed, it is stifled stifled before body of a gun two ends are fixing with the back, handle is connected with handle, driving chip and spring are housed on the push rod, the body of a gun and handle fuse, porose on the handle, be welded with blade on the handle, packing element inserts in the hole, blade can cut away the tube mouth, push jack before the push rod left end fixes one with nut, advance the plastic squeeze of packing element piston forward, driving chip can prevent that throw-out lever retreats, and drives spring driving chip is resetted, this glue spraying gun is the same with other numerous glue spraying guns all a unsolved for a long time problem, be exactly the water clock problem of glue, the operator when using glue spraying gun, the push jack plastic squeeze of marching forward before pulling the handle push rod and driving, when unclamping handle, push rod halts, and driving chip is being controlled push rod again and can not retreated, and at this moment remaining pressure still arranged in the packing element, thereby glue also can flow out, and the water clock problem comes to this and produces.In addition, commercially available glue spraying gun also has a problem, in the time of need not leading to plastic pin exactly, will lead to plastic pin playback, because of there not being securing device, and is easy to swing, and is very dangerous.

Main purpose of the present utility model is to provide a kind of dropless glue gun at the problems referred to above, this glue spraying gun utilizes adjustment part fine setting push rod, when the operator unclamps handle, having push rod in arms under the effect of adjustment part overbottom pressure in packing element shrinks back, pressure moment in the packing element is released, thus glue with regard to can not water clock in outer.

Another purpose of the present utility model is, by steady needle tray is set under the body of a gun, and makes logical plastic pin make it can not swing in this groove in time spent holding not, avoids hurting sb.'s feelings.

Main purpose of the present utility model is realized by following technical scheme:

A kind of dropless glue gun comprises: stifled before the body of a gun, body of a gun front end install, preceding stifled lower ending pivot is adorned a logical plastic pin, and it is stifled that the rear end of the body of a gun installs the back, and stifled position, the center of circle, back is provided with seam formula through hole; Stifled outside, back installs handle, and a concentric via hole of seam formula through hole that blocks up with the back is set on the handle; The leading portion of push rod installs preceding push jack, and suit driving chip and driving spring on the push rod, by via hole and seam formula through hole, is threaded onto in the body of a gun; Adorn a handle by the pivot pivot in the handle, suit one dialing spring is provided with driving shaft on this pivot on the handle, and driving chip is set with adjustment part on the described push rod before stretching the driving shaft that places in the handle.

The purpose of this utility model can also realize by next technical scheme:

Aforesaid dropless glue gun, described adjustment part are the silica gel circle, and this silica gel circle is placed in the seam position of seam formula through hole.

Another purpose of the present utility model can realize by next technical scheme:

Aforesaid dropless glue gun, the described body of a gun is provided with the ring convex ridge, and this convex ridge portion is provided with steady needle tray.

Advantage of the present utility model and good effect be by above technical scheme as can be known:

Significant contribution of the present utility model is, can effectively prevent the water clock of glue, saves glue, for the operator builds a clean working region; Simultaneously, the utility model also provides steady needle construction for the audient, makes it safer reliable, believes and can be liked by numerous audients.

For further understanding technology contents of the present utility model, characteristics and effect, exemplify following preferred embodiment now, and conjunction with figs. is described in detail as follows:

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

Fig. 2 is the local enlarged diagram of the utility model.

Fig. 3 is the structural representation of the glue spraying gun commonly used.

The structure of the dropless glue gun of the utility model topic being stated below in conjunction with accompanying drawing and preferred embodiment and feature, effect elaborate:

As depicted in figs. 1 and 2, the utility model comprises: the body of a gun 1 generally is half thick bamboo tube shape, and its ring convex ridge portion 12 is provided with steady needle tray 123.Body of a gun front end is welded and one has the preceding stifled 2 of U type gap, and preceding stifled bottom pivot is adorned a logical plastic pin 21, and the rear end of the body of a gun is welded stifled 3 behind the dome shape, and stifled position, the center of circle, back is provided with seam formula through hole 31; Its seam position 311 is used for ccontaining adjustment part 5, and the outside stifled in the back installs handle 8, and handle generally is the entrainment shape, and it installs with the stifled mode that can four hole flanging riveteds in back, like this body of a gun with preceding stifled, after block up and handle is combined into an integral body securely.Seam formula through hole 31 concentric positions in the ridge of handle and back on stifled are provided with a via hole 81, for placing push rod 4, this push rod is the J type, and push rod passes via hole 81, and the suit driving chip 7 successively, driving spring 6, adjustment part 5 passes seam formula through hole 31 again, and the leading portion of push rod installs preceding push jack 41, and push rod just has been threaded onto in the body of a gun like this, described adjustment part 5 selects for use the silica gel circle the most suitable; Adorn a handle 9 by pivot 10 pivots in the handle, its frame mode is the technology of commonly using.Suit one dialing spring 11 on this pivot, the upper end of handle is provided with driving shaft 91, before driving chip 7 is stretched the driving shaft that places in the handle, for improving the functional of glue spraying gun Jiao Zui hole 82 can be set on handle, and on handle relative set one blade 92, its structure is the technology of commonly using, and does not repeat them here.

When using the utility model to play glue, the packing element of in the half thick bamboo tube shape body of a gun, packing into, drive driving chip and gnaw before the push rod and then extrude glue in the packing element by pulling handle, produce certain pressure in the packing element simultaneously, when unclamping handle, under the effect of adjustment part overbottom pressure in packing element, have in arms under the push rod slow astern, instantaneous time has just released the pressure in the packing element, and Jiao Zui has not gone out glue at once, has effectively prevented the water clock of glue.Logical plastic pin is no the time, and card crouches in steady needle tray, and it is safe and reliable can not swing.

The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did.
