Description

Spiral pressure grease gun

One, technical field: the utility model relates to a kind of grease gun, relates in particular to a kind of firmly for a short time, and extrusion capacity is the spiral pressure grease gun of control easily.

Two, background technique: at present the grease gun that uses is to adopt the mode of pushing the gun barrel inner carrier, and butter is extruded, and its required thrust is bigger, and extrusion capacity is wayward, and thrust is excessive, and the butter of then extruding will be excessive, has not only wasted but also easy dirty oiling place.Traditional grease gun is structure as a whole, and volume is bigger, carries inconvenience.Some narrow positions of machine, equipment, limited space, the single butter of annotating that often is difficult to.

Three, summary of the invention: the purpose of this utility model is to provide a kind of laborsaving, convenient, easy spiral pressure grease gun of controlling of extrusion capacity.

The purpose of this utility model is achieved in that spiral pressure grease gun, by gun barrel, the rifle head that links to each other with the gun barrel front end, places screw rod, piston in the gun barrel, and the handle that is connected with screw rod composition.Gun barrel is not sealed hollow bodies of two ends, is connected with a cap at its front end, and tube cap center is equiped with oil outlet, and oil outlet is communicated with gun barrel is interior, is connected with the chassis at the gun barrel back-end sealing, and the center chassis perforate is inserted with screw rod in the hole.The screw rod front portion is positioned at the gun barrel cavity, and the surface has outside thread, is connected with piston on it, and the screw rod rear portion is positioned at outside the gun barrel, and the surface also has outside thread, is with lock sleeve on the screw rod rear portion, and connecting rod and lock sleeve spin.Connecting rod end in addition is provided with ring connecting rod cover, is connected with handle in the connecting rod cover.

Owing to carry out technique scheme, this grease gun can't be extruded butter or extrude excessive problem with regard to efficiently solving because of firmly too small, excessive, its outer rifle head, connecting rod, handle that is connected on the gun barrel all can be dismantled easily, makes whole rifle volume reduce greatly, is convenient for carrying.

Four, description of drawings: the technical solution of the utility model is provided by following drawings and Examples.

Five, embodiment:

The utility model is not subjected to following embodiment's restriction, can determine concrete mode of execution according to the technical solution of the utility model and actual conditions.

Embodiment: as shown in Figure 1, spiral pressure grease gun by gun barrel 5, with the rifle head 7 that gun barrel 5 front ends link to each other, place screw rod 3, piston 4 in the gun barrel 5, and handle 10 compositions that are connected with screw rod 3.Gun barrel 5 is not sealed hollow bodies of two ends, is connected with a cap 6 at its front end, and tube cap 6 centers are equiped with oil outlet 16,

oil outlet

16 and 5 interior connections of gun barrel, the taper rifle head 7 of circle after being connected with paracone on the oil outlet 16, the 7 interior perforations of rifle head are porose, with oil outlet 16 conductings.Be connected with chassis 2 at gun barrel 5 back-end sealings, chassis 2 center drillings are inserted with screw rod 3 in the hole.Screw rod 3 front portions are positioned at gun barrel 5 cavitys, and the surface has outside thread, are connected with piston 4 on it, and ring piston 4 outer periphery middle part has a circle groove, the embedded seal ring 18 that is with of groove.Be filled with thick objects such as butter, latex at gun barrel 5 cavitys that are positioned at piston 4 front portions.Screw rod 3 rear portions are positioned at outside the gun barrel 5, and the surface also has outside thread, are with lock sleeve 8 on screw rod 3 rear portions, be rotary with nut 13, two nuts 13 on the screw rod 3 of lock sleeve 8 both sides lock sleeve 8 is locked on screw rod 3 rear portions.Lock sleeve 8 is a cavity cover, and the one side has through hole, is rotary with locking element 1 in this through hole, and locking element 1 is a screw rod.On 8 pairs of sides of lock sleeve of aforementioned through-hole, also have through hole, be connected with connecting rod 9 in it, connecting rod 9 end in addition is provided with ring connecting rod cover 14, be connected with handle 10 in the connecting rod cover 14, handle 10 front portions have outside thread, the front end exposure is overlapped at connecting rod and is rotary with nut 13, two nuts 13 on handle 10 front portions of 14 both sides connecting rod cover 14 is locked at handle 10 front portions outside connecting rod cover 14.

As shown in Figure 2, the edge of circular piston 4 has arc notch, along the front and back length direction arc lug, nib 11 that cooperates with this breach is housed even on gun barrel 5 inwalls, and it can prevent that piston 4 from rotating with screw rod 3.Piston 4 also can be ellipse, and this moment, gun barrel 5 also was supporting with it ellipse.Also can leave arc notch or flat breach respectively, promptly on gun barrel 5 inwalls, make two supporting lug, nibs 11 of shape with it this moment at the diameter two ends of circular piston 4.Also can leave a flat breach, promptly on gun barrel 5 inwalls, make a supporting lug, nib 11 of shape with it this moment at the edge of circular piston 4.On chassis 2, have and the corresponding notch 12 of lug, nib 11 shapes.Can guarantee that so 4 in piston seesaws, and can not rotate in screw rod 3 rotations.

Rotation handle 10 drives screw rod 3 and rotates, and piston 4 then can only rotate forward and backward motion under the drive at screw rod 3 owing to do not rotate, and in the 4 proal whiles of piston, can slowly the butter in the gun barrel 5 be extruded, and the extrusion capacity of assurance butter is even.When not using, promptly back out nut 13, unscrew locking element 1, handle 10, connecting rod 9 and lock sleeve 8 can be pulled down, to be convenient for carrying.

As shown in Figure 3, in some narrow positions of machine, equipment, under the situation of limited space, can be on gun barrel 5 outer walls nested rack 17, spin elbow 15, flexible pipe, rifle head 7 of order on oil outlet 16.Singlely can a hand-held gun 7 aim at and add pump nozzle, another hand rotates handle 10 filling butter.Under the big situation of butter filler amount, change heavy caliber gun barrel 5, one people's hand-held gun 7 aligning into and add pump nozzle, another people rotates handle 10 filling a long way off.Except all the other component, gun barrel 5 is an expendable consumed product.At ordinary times, the outlet port of tube cap 6 centers installing oil outlet 16 is stamped door or is plugged with obstruction.

Above technical characteristics has constituted most preferred embodiment of the present utility model, and it has stronger adaptability and best implementation result, can increase and decrease inessential technical characteristics according to actual needs, satisfies the needs of different situations.
