Specific embodiment
It is described further referring to figs. 1 to embodiment of the Fig. 6 to the stretching-machine that the utility model saves power source.
Embodiment one:
As shown in Figure 1-3, a kind of stretching-machine for saving power source, including take blame for others 3 and fuel tank 7,3 and the fuel tank of taking blame for others
It is provided with oil inlet pipe 8 and oil return line 6 between 7, is provided with check valve 9 on the oil inlet pipe 8, on the oil return line 6
It is provided with overflow valve 5, described take blame for others 3 includes cylinder body 13 and piston 12, and the piston 12 is provided with towards 13 interior side of cylinder body
Push rod 11,11 lower end of push rod are connected with reset drives mechanism through and out cylinder body 13,11 lower end of push rod, wherein multiple
Position driving mechanism can be cylinder 10 or spring 14, and those skilled in the art should know to make push rod 11 through and out cylinder body
13, through-hole is opened up in the bottom of cylinder body 13 and is passed through for push rod 11, and in this through hole, sealing prevents oil leak.
It the preferred overflow valve 5 and takes blame for others and is provided with pressure gauge 4 between 3.
There is provided power by cylinder 10 or spring 14 moves upwards push rod 11 with piston 12, unidirectional in oil inlet pipe 8
Valve 9 will be opened in the oil pocket 15 for making entering in fuel tank 7 take blame for others 3 again, and oil pocket 15 at this time is piston 12, cylinder body 13 and push rod 11
The region surrounded jointly, the diameter of certain push rod 11 are less than the internal diameter of oil pocket 15, stop when 3 piston 12 of taking blame for others reaches highest point
Only, the master cylinder 1 of top will push, and check valve 9 can not be connected, 3 offer back pressures of taking blame for others at this time, when pressure is more than setting for overflow valve 5
When definite value, overflow valve 5 is back to the oil in oil pocket 15 in fuel tank 7, and wherein pressure gauge 4 being capable of more convenient staff's sight
Examine the provided back pressure in oil pocket 15 all the time.
When wherein using cylinder 10, cylinder 10 need to be connected with air accumulator, and air accumulator is then usually provided by air compressor machine
Compressed gas, indispensable equipment when wherein air compressor machine is mostly enterprise's production, there is no need to individually purchase, and the pressure in air accumulator
Contracting gas can be stored, and only need to connect cylinder 10 by tracheae with air accumulator, when needing to reset piston 12 every time,
It is activated individually without air compressor machine, only need to be using the compressed gas in air accumulator, therefore the existing of enterprise can be efficiently used
Equipment is that piston 12 provides power source without individually spending cost.
When using spring 14, preferably as shown in figure 3, directlying adopt compressed spring, mounting structure is simple, only needs lower end
Fixed, upper end connects push rod 11, then entirely without energy consumption when 3 piston 12 of taking blame for others resets, is not necessarily to electricity consumption, and safeguard at
This is almost without as needed to select spring 14, manufacture life as long as piston 12 can be jacked up reset by the elastic force of spring 14
Cost is produced also to substantially reduce simultaneously.
Embodiment two:
As shown in figure 4, the stretching mode for 3 pistons 12 of only taking blame for others in the present embodiment makes change, tool different from embodiment one
Body are as follows: the reset drives mechanism is only with spring 14 in the present embodiment, and wherein spring 14 is located at piston 12 and 13 bottom of cylinder body
Between portion, what those skilled in the art understand that, spring 14 is preferably compressed spring 14 at this time, as long as piston can be given
12 power moved upwards.
Spring 14 is placed in inside cylinder body 13, without opening up hole location in 13 bottom of cylinder body, structure is simple, suitable for taking blame for others 3
12 stroke of piston it is shorter when, reduce the entire mechanism that back pressure is provided occupied space in the vertical direction.
Embodiment three:
As shown in Figure 5 and Figure 6, the stretching mode of 3 pistons 12 of only taking blame for others in the present embodiment makes change and embodiment one not
Together, specifically: without open up through-hole in the bottom of cylinder body 13, but reset drives mechanism be placed in take blame for others 3 side, it is described multiple
Position driving mechanism and piston 12, which stretch out between 13 part of cylinder body, is provided with connector 16, can equally reduce entire offer back pressure
Mechanism occupied space in the vertical direction.
Wherein there are two preferred reset drives mechanism settings at least, in the present embodiment for two, two resets are driven
Motivation structure be symmetricly set on take blame for others 3 side, and by horizontal a connecting plate or connecting rod as connector 16 by reset drive
Motivation structure and piston 12 connect.
It is directly fixedly connected between connector 16 and piston 12, the top for being attached to piston 12 is also attached to work
Fill in 12 top upper positions.
Wherein although Fig. 5 and Fig. 6 illustrates cylinder and spring is the structure of upward roof connecting, but those skilled in the art
It should be clear that cylinder and spring can also be inverted, that is, be placed in the top of connector, by the contraction of cylinder or the contraction of spring come
It realizes the reset of piston, the separate connector side of cylinder and spring need to be only fixed in the rack of stretching-machine at this time.
The above is only the preferred embodiment of the utility model, and the protection scope of the utility model is not limited merely to
Above-described embodiment, technical solution belonging to the idea of the present invention belong to the protection scope of the utility model.It should refer to
Out, for those skilled in the art, it is without departing from the principle of the utility model it is several improvement and
Retouching, these improvements and modifications also should be regarded as the protection scope of the utility model.
