It should be noted that the description of these implementation methods is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in each implementation method of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0023] Example 1, please refer to Figure 1-Figure 6 A lubrication device for mechanical equipment includes a syringe 1 and a needle 2, the needle 2 is installed on the lower wall of the syringe 1, a liquid level observation window 3 is opened on the outer wall of the syringe 1, a guide structure is installed on the upper end surface of the syringe 1, an injection structure is installed on the inner wall surface of the syringe 1, and a storage structure is installed on the upper end surface of the guide structure.

[0024] See also Figure 1-Figure 6 The guide structure includes: a threaded positioning groove 4, a sealing ring 5 and a plurality of injection guide holes 6; the threaded positioning groove 4 is installed on the upper end surface of the injection barrel 1, the sealing ring 5 is installed on the side wall surface outside the threaded positioning groove 4, and the plurality of injection guide holes 6 are respectively opened on the lower wall surface inside the threaded positioning groove 4.

[0025] See also Figure 1-Figure 6The injection structure includes: an injection plug 7, a drainage groove 8, a return spring 9, a ball plug 10, an injection push tube 11, a connecting seat 12 and a connecting ring 13; the injection plug 7 is installed on the inner wall surface of the injection barrel 1, the drainage groove 8 is opened on the inner wall surface of the injection plug 7, the return spring 9 is installed on the inner wall surface of the drainage groove 8, the ball plug 10 is installed on the upper wall surface of the return spring 9, the injection push tube 11 is installed on the upper wall surface of the injection plug 7, the connecting seat 12 is installed on the upper wall surface of the injection push tube 11, and the connecting ring 13 is installed on the upper wall surface of the connecting seat 12.

[0026] See also Figure 4 The injection push tube 11 is provided with a plurality of drainage holes 19 . In this embodiment, when the injection plug 7 moves, the lubricating oil in the injection barrel 1 flows into the drainage groove 8 through the drainage holes 19 .

[0027] In this embodiment, the ball plunger 10 is moved by the reset spring 9, so that the lubricating oil above the injection plug 7 in the syringe 1 flows into the lower part of the injection plug 7 through the drainage groove 8. A scale is engraved on the liquid level observation window 3. The pulling position of the injection plug 7 can be adjusted according to the scale to accurately control the output amount of the lubricating oil from the needle 2, thereby realizing multiple and accurate output of the lubricating oil.

[0028] Specifically, the operator inserts a finger into the connecting ring 13 and pulls it in the opposite direction of the needle 2. The connecting ring 13 drives the injection push tube 11 to drive the injection plug 7 to move along the injection barrel 1 through the connecting seat 12. During this period, the lubricating oil in the injection barrel 1 enters the drainage groove 8 through the drainage hole 19. The ball plug 10 compresses the reset spring 9 under the action of the flow of the lubricating oil. The lubricating oil above the injection plug 7 flows into the bottom of the injection plug 7 through the drainage groove 8. When the connecting ring 13 is not pulled, the reset spring 9 is reset, driving the ball plug 10 to block the drainage groove 8. When the connecting ring 13 is pushed downward, the lubricating oil below the injection plug 7 flows out through the needle 2. There is a scale engraved on the liquid level observation window 3. The pulling position of the injection plug 7 can be adjusted according to the scale to accurately control the output of the lubricating oil from the needle 2. The sealing ring 5 is used to prevent the lubricating oil from flowing out of the injection barrel 1 along the injection push tube 11.

[0029] Example 2, please refer to Figure 1-Figure 4 The storage structure includes: a threaded seat 14, a liquid storage tank 15, a plurality of storage air guide holes 16, an auxiliary cap 17 and a plurality of auxiliary air guide holes 18; the threaded seat 14 is installed on the inner wall surface of the threaded positioning groove 4, and is threadedly connected to the threaded positioning groove 4, the liquid storage tank 15 is installed on the upper wall surface of the threaded seat 14, a plurality of storage air guide holes 16 are respectively opened on the upper wall surface of the liquid storage tank 15, the auxiliary cap 17 is installed on the upper wall surface of the liquid storage tank 15, and a plurality of auxiliary air guide holes 18 are respectively opened on the upper wall surface of the auxiliary cap 17.

[0030] See also Figure 6A plurality of storage guide holes 20 are provided on the lower wall surface of the liquid storage tank 15 . In this embodiment, the lubricating oil in the liquid storage tank 15 enters the injection cylinder 1 through the storage guide holes 20 .

[0031] See also Figure 6 The side wall of the auxiliary cap 17 is provided with a plurality of anti-skid patterns. In this embodiment, the anti-skid patterns can increase the friction between the auxiliary cap 17 and the hand.

[0032] In this embodiment, by rotating the auxiliary cap 17 around the liquid storage tank 15, the air pressure in the connection between the injection barrel 1 and the liquid storage tank 15 can be adjusted, so that the lubricating oil in the liquid storage tank 15 can enter the adjustment injection barrel 1 along a number of injection guide holes 6 and storage guide holes 20 when pushing the connecting ring 13.

[0033] Specifically, when the operator drives the liquid storage tank 15 to screw the threaded seat 14 into the threaded positioning groove 4, a number of injection guide holes 6 overlap with the storage guide holes 20. When the operator pulls the connecting ring 13, the auxiliary cap 17 is first rotated to misalign the several storage air guide holes 16 with the several auxiliary air guide holes 18 to stabilize the air pressure in the liquid storage tank 15. At this time, pulling the connecting ring 13 again will prevent the lubricating oil in the liquid storage tank 15 from flowing out of the several storage air guide holes 16. When the connecting ring 13 is pushed, the auxiliary cap 17 is turned again to overlap the several storage air guide holes 16 with the several auxiliary air guide holes 18. At this time, when the lubricating oil in the injection barrel 1 flows out from the needle 2, the lubricating oil in the liquid storage tank 15 enters the injection barrel 1 through the storage guide holes 20.

For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
