Detailed description of the invention
Fig. 1 is the schematic cross-sectional view of the utility model；
In figure: 1 mentions flitch, 2 material extraction rods, 3 filters, 4 check-valves, 5 core bar valve bodies, 6 check valves, 7 connecting rods, 8 pneumatically
Pump output rod, 9 oil outlets, the 10 pneumatic pump housings, 11 connected pipes, 12 oil pump bodies, 13 stop collars, 14 ring check valve seats, 15 into
Oil pipe, the oil inlet of 16 oil inlet pipe side walls, the fuel feed hole of 17 core bar valve bodies, the oil outlet of 18 core bar valve bodies, 19 check-valves top
Oil inlet notch, 20 sealing rings.
Specific embodiment
The utility model is further illustrated in conjunction with accompanying drawings and embodiments, as shown in Figure 1, a kind of Pneumatic oiling device proposes oily increasing
Press mechanism, ring check valve seat 14 are fastened between oil pump body 12 and oil inlet pipe 15, the core bar valve body 5 being placed in oil pump body 12
Inside is equipped with check valve 6, and the both ends of core bar valve body 5 are connected with connecting rod 7, material extraction rod 2 respectively, are fixedly connected on material extraction rod 2
Flitch 1 is mentioned, check-valves 4 is equipped on the outside of material extraction rod 2, connecting rod 7 is connected with air driven pump output rod 8, is provided in oil inlet pipe 15
Filter 3.
The utility model to propose oily pressurization as follows:
Firstly, oil liquid enters oil inlet pipe from oil inlet 16 when air driven pump output rod 8 is moved upwards from lower limit position
15, the oil liquid into oil inlet pipe 15 is proposed the compressing of flitch 1 by filter 3, enters oil pump body from 14 hole of ring check valve seat
12, the gap of check-valves outer wall Yu oil pump body inner wall is flowed through, around the oil inlet notch on 4 top of check-valves for being limited the limit of ring 13
19, it is gradually filled with oil pump body 12；
Then, after air driven pump output rod 8 reaches upper limit position then when moving downward, check-valves 4 closes (check-valves
Decline, the hole of ring check valve seat is blocked in the bottom of check-valves), core bar valve body 5 oppresses the intracorporal oil liquid of oil pump through core bar
