Before adding lubricating oil, first place the sealing block 9210 and the sealing seat 929 in the third channel 9211, then turn the cover nut 924 to adjust its position on the extension tube, adjust the position of the connecting plate 927 in the third channel 9211, so that the spring 928 is in a compressed state, Then, by turning the second knob 925, the moving second knob 925 can drive the adjusting rod 926 to move, thereby adjusting the position of the connecting plate 927, changing the deformation of the spring 928, and thus changing the pressure of the sealing block 9210 on the bottom of the third channel 9211. Then, when the operator turns the first knob 912, the lubricating oil can flow into the first channel 922 from the oil outlet 918 on the transport seat 913. As the operator continues to turn, the lubricating oil can fill the first channel 922. Then, the first knob 912 is continued to be turned. At this time, the oil pressure can generate a thrust on the sealing block 9210, so that it can move away from the third channel 92 The bottom of 11, and then the lubricating oil can move from the first channel 922 to the third channel 9211, and be transported along the third channel 9211 to the second channel 923, so that the lubricating oil can flow out from the oil outlet assembly 93, and the lubricating oil adding work is completed. At the same time, when the hydraulic oil is added through the above-mentioned device, after the second channel 923 is full of lubricating oil, the first knob 912 is continued to be rotated, and then the lubricating oil can push the sealing block 9210 to move, so that it has a certain initial velocity. When it flows into the lock core, the lubricating oil can collide with the lock core, so that the lubricating oil can be dispersed into multiple oil droplets, thereby increasing the lubrication area of ​​the lubricating oil.

[0036] In a further embodiment, during the refueling process of the device, the connecting plate 927 can be first rotated to make it move on the adjusting rod 926 to adjust the distance between it and the free end of the adjusting rod 926, or the cover nut 924 can be rotated to adjust the overlapping area between the cover nut 924 and the extension tube, or the second knob 925 can be rotated to adjust the position of the adjusting rod 926 in the third channel 9211, thereby changing the area where the connecting plate 927 is located, and the deformation of the spring 928 is changed by the above method, and the oil pressure required for the sealing block 9210 to be away from the bottom of the third channel 9211 is adjusted, so that the lubricating oil can enter the third channel 9211 at a predetermined speed. At the same time, when there is no lubricating oil in the oil storage pipe, the position of the connecting plate 927 can be adjusted by rotating the second knob 925, thereby changing the deformation of the spring 928, so that there is a gap between the sealing block 9210 and the bottom of the third channel 9211, and the lubricating oil in the first channel 922 can be injected into the lock cylinder.

[0037] In a further embodiment, through the above-mentioned method of meshing the driving gear 915 and the driven gear 916, the oil outlet end 918 is blocked, so that the lubricating oil can flow out at a certain speed. However, this method still has some problems. When the deformation of the spring 928 is too large, the extrusion pressure between the sealing block 9210 and the bottom of the third channel 9211 is too large, which can seal the lubricating oil. However, due to the excessive extrusion pressure, the oil pressure in the first channel 922 will be too large, which will cause damage to the gear or the sealing block 9210. When the sealing block 9210 is damaged, it will cause leakage of the lubricating oil; and when the deformation of the spring 928 is too small, a gap will appear between the sealing block 9210 and the third channel 9211, and the lubricating oil will flow along the gap from the lock core to the outside of the lock core, causing pollution of the cabinet door and waste of lubricating oil.

[0038] In order to solve the above problems, the present device is provided with an oil outlet assembly 93, which includes an oil outlet shell 931, a rotating shaft 933 connected to the oil outlet shell 931, a third knob 932 arranged at one end of the rotating shaft 933, a locking block 934 arranged at the other end of the rotating shaft 933 and located in the oil outlet shell 931, an oil outlet nozzle 936 connected to the oil outlet shell 931, and a discharge pipe 935 arranged in the oil outlet shell 931; wherein one end of the discharge pipe 935 is located in the second channel 923, and the other end of the discharge pipe 935 is located at the oil outlet nozzle 936; the locking block 934 is arranged at the other end of the rotating shaft 933 and located in the oil outlet shell 931, and the oil outlet nozzle 936 is arranged in the oil outlet shell 931. The tightening block 934 is an elliptical structure; by turning the third knob 932, the moving third knob 932 can drive the rotating shaft 933 to rotate, thereby changing the position of the locking block 934. In the non-fueling state, the long axis area of ​​the elliptical locking block 934 abuts against the discharge pipe 935 and deforms the discharge pipe 935, thereby clamping the discharge pipe 935 to prevent the lubricating oil from flowing out of the discharge pipe 935. Otherwise, the elliptical locking block 934 does not abut against the discharge pipe 935, and the discharge pipe 935 is in a normal oil discharge state, thereby avoiding the problem of lubricating oil leakage in the non-fueling state.

With the movement of the driving gear 915 and the driven gear 916, the lubricating oil can flow out from the oil outlet 918. In the process, the oil output of the oil outlet 918 and the rotation angle of the first knob 912 are adjusted. With the rotation of the first knob 912, the tooth grooves on the driving gear 915 or the driven gear 916 can be rotated to the same angle, and the lubricating oil is located in the tooth groove, so that the amount of lubricating oil added can be controlled to avoid adding too much lubricating oil and avoid wasting lubricating oil.Before adding lubricating oil, first place the sealing block 9210 and the sealing seat 929 in the third channel 9211, then turn the cover nut 924 to adjust its position on the extension tube, adjust the position of the connecting plate 927 in the third channel 9211, and make the spring 928 in a compressed state, and then turn the second knob 925, and then the moving second knob 925 can drive the adjusting rod 926 to move, thereby adjusting the position of the connecting plate 927, changing the deformation of the spring 928, and thus changing the sealing block 9210 to the third channel The pressure at the bottom of the third channel 9211 is increased, and then when the operator turns the first knob 912, the lubricating oil can flow from the oil outlet 918 on the transport seat 913 into the first channel 922. As the operator continues to turn, the lubricating oil can fill the first channel 922. Then, the first knob 912 is turned continuously. At this time, the oil pressure can generate a thrust on the sealing block 9210, so that it can move away from the bottom of the third channel 9211, and then the lubricating oil can move from the first channel 922 to the third channel 9211 and be transported along the third channel 9211. To the second channel 923, so that the lubricating oil can flow out from the oil outlet assembly 93, completing the lubricating oil addition work. At the same time, when the hydraulic oil is added through the above device, since the second channel 923 is full of lubricating oil, the first knob 912 is continued to be turned, which will enable the lubricating oil to push the sealing block 9210 to move, so that it has a certain initial velocity. When it flows into the lock core, the lubricating oil can collide with the lock core, so that the lubricating oil can be dispersed into multiple oil droplets, thereby increasing the lubrication area of ​​the lubricating oil; when the oil outlet assembly 93 is working, By turning the third knob 932, the moving third knob 932 can drive the rotating shaft 933 to rotate, thereby changing the position of the locking block 934. In the non-refueling state, the long axis area of ​​the elliptical locking block 934 abuts against the discharge pipe 935 and deforms the discharge pipe 935, thereby clamping the discharge pipe 935 to prevent the lubricating oil from flowing out of the discharge pipe 935. Otherwise, the elliptical locking block 934 does not abut against the discharge pipe 935, and the discharge pipe 935 is in a normal oil discharge state, thereby avoiding the problem of lubricating oil leakage in the non-refueling state. ;
