Further, the volume of described cylindrical shell is consistent with the volume of hand grease gun gun barrel.
As a kind of preferred version, described cylindrical shell is big or small consistent with the hand grease gun gun barrel.
Further, described linkage structure is the cover that is threaded that matches with hand grease gun gun barrel outside thread.
Further, described cylindrical shell is one-body molded with the cover that is threaded.
Further, described cylindrical shell the other end sealing, an end of described cylindrical shell sealing is provided with exhaust structure; Be provided with pressure spring between one end of described piston and cylindrical shell sealing.
Further, be provided with the one-way locking mechanism of piston pulling rod between the end of described piston pulling rod and cylindrical shell sealing, the locking direction of described one-way locking mechanism is consistent with the elastic force direction that pressure spring acts on piston.
Further, described one-way locking mechanism is made of the locking plate that zigzag fashion bayonet socket, cylindrical shell on the piston pulling rod seal an end; Described exhaust structure is made of the mounting hole of locking plate.
Further, described hermetic seal structure is made of one deck O RunddichtringO at least.
The beneficial effects of the utility model are: during use, at first piston is pushed into the end of cartridge openings one end by piston pulling rod, then cartridge openings one end end is inserted in the butter, then by piston pulling rod with piston toward pulling back, by atmospheric pressure butter is sucked in the cylindrical shell; After cylindrical shell is filled butter, the cylindrical shell that connects hand grease gun gun barrel and this oil-filling device by linkage structure, make both be communicated with, by piston pulling rod the end of piston to oil-filling device opening one end promoted then, the butter in the oil-filling device cylindrical shell is squeezed in the gun barrel of hand grease gun under piston action.Therefore, can carry out oiling to grease gun fast, easily by this oil-filling device.In the process of the butter in this oil-filling device cylindrical shell being clamp-oned in the hand grease gun gun barrel, the piston of hand grease gun, positioning tie bar are clamp-oned and are retreated with butter, therefore can effectively avoid sneaking into of air.
Description of drawings
Fig. 1 is a structure sketch drawing of the present utility model.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As shown in Figure 1, hand grease gun oil-filling device of the present utility model, the piston 2 that comprises cylindrical shell 1, axially in cylindrical shell 1, is slidingly matched along cylindrical shell 1 with it, piston 2 is provided with the sealing configuration that cooperates with cylindrical shell 1 inwall hermetic seal, described cylindrical shell 1 one end openings, an end end of described opening is provided with the linkage structure that links to each other with the hand grease gun gun barrel; Be provided with by 2 in piston and through the other end of cylindrical shell 1 relative opening one end and extend to piston pulling rod 3 outside the cylindrical shell 1, described piston pulling rod 3 is fixedlyed connected with piston 2.
During use, at first piston 2 is pushed into the end of cylindrical shell 1 opening one end, then cylindrical shell 1 opening one end end is inserted in the butter by piston pulling rod 3, then by piston pulling rod 3 with piston 2 toward pulling back, by atmospheric pressure butter is sucked in the cylindrical shell 1; After cylindrical shell 1 is filled butter, the cylindrical shell 1 that connects hand grease gun gun barrel and this oil-filling device by linkage structure, make both be communicated with, by piston pulling rod 3 end of piston 2 to oil-filling device opening one end promoted then, the butter in the oil-filling device cylindrical shell 1 is squeezed in the gun barrel of hand grease gun under piston 2 effects.Therefore, can carry out oiling to grease gun fast, easily by this oil-filling device.In the process of the butter in this oil-filling device cylindrical shell 1 being clamp-oned in the hand grease gun gun barrel, the piston of hand grease gun, positioning tie bar are clamp-oned and are retreated with butter, therefore can effectively avoid sneaking into of air.
Piston pulling rod 3 can be welding etc. with fixedlying connected of piston 2, but for the ease of safeguarding, best, be to be threaded.
The volume of this oil-filling device cylindrical shell 1 can greater than, also can be less than the volume of hand grease gun gun barrel.But less than the time, need repeatedly to add, increase operating procedure, and continuous twice is infused in its easy entrained air in position at interval; Greater than the waste that then may cause butter.Therefore, best, the volume of described cylindrical shell 1 is consistent with the volume of hand grease gun gun barrel.
Estimate volume for convenience, the convenient making, concrete, described cylindrical shell 1 is big or small consistent with the hand grease gun gun barrel.
Its effect of above-mentioned linkage structure is to form the connection of gun barrel and cylindrical shell 1 and avoid air sneaking in injection process, can be the coupler that a columniform elastic caoutchouc cover or external diameter and hand grease gun gun barrel internal diameter adapt.But for the consideration that prevents that gas from sneaking into, best, described linkage structure is the cover 6 that is threaded that matches with hand grease gun gun barrel outside thread.
The above-mentioned body 6 that is threaded can be the structure of a similar pipe joint, but makes for convenience, operates, and described cylindrical shell 1 is one-body molded with the cover 6 that is threaded.When injecting butter in grease gun, guaranteed the sealing that cylindrical shell 1 is connected with gun barrel by the body 6 that is threaded, so just not having butter flow to the outside, reduces the waste of grease, has kept cleaning, so fuel-saving environmental protection.Grease is separated with the external world always, has avoided grease to be polluted.
When butter being injected in the gun barrel of hand grease gun, need overcome outside the resistance of butter itself, also need to overcome the elastic force of grease gun oiling spring.Therefore operation for convenience, described cylindrical shell 1 the other end sealing, an end of described cylindrical shell 1 sealing is provided with exhaust structure; Be provided with pressure spring 4 between one end of described piston 2 and cylindrical shell 1 sealing.
Be provided with the one-way locking mechanism of piston pulling rod 3 between the end that the operation when sucking butter for convenience, described piston pulling rod 3 and cylindrical shell 1 are sealed, the locking direction of described one-way locking mechanism is consistent with the elastic force direction that pressure spring 4 acts on piston 2.
Above-mentioned one-way locking mechanism can be a ratch mechanism etc., and above-mentioned exhaust structure also can be hole etc. arbitrarily.But for simplified structure, described one-way locking mechanism is made of the locking plate 5 of the zigzag fashion bayonet socket 8 on the piston pulling rod 3, cylindrical shell 1 sealing one end; Described exhaust structure is made of the mounting hole of locking plate 5.When sucking butter, prevent that by locking plate 5 and cooperating of bayonet socket 8 piston pulling rod 3 is pushed out under the effect of pressure spring 4; When the hand grease gun oiling, extract locking plate 5 out, locking plate 5 breaks away from all the time with bayonet socket 8, by promoting piston pulling rod 3 and under the power-assisted of pressure spring 4 butter being injected in the gun barrel of hand grease gun.
Above-mentioned hermetic seal structure then is in order to guarantee the suction of butter, and it can be the structure that can realize hermetic seal arbitrarily, and is concrete, and described hermetic seal structure is made of one deck O RunddichtringO 7 at least.In order to guarantee sealing effect, hermetic seal structure concrete in the example of Fig. 1 is made of two-layer O RunddichtringO 7.
The utility model is applicable to the oiling of all kinds of grease guns, and especially open-air occasion is as the field construction building site at excavator place etc.
