One end of the injection head has a connecting cylinder. A long hole is provided in the middle of the injection rod body. The front section of the injection rod body is a reduced-diameter section. The injection rod is threadedly connected to the connecting cylinder of the injection head through a sealing structure. An oil pipe is also connected to the injection head and extends into the long hole of the injection rod body. An annular oil groove is provided on the outer ring surface of the injection head, and a number of oil outlet holes are provided in the oil groove. The oil outlet holes are communicated with the oil pipe. Water inlet holes and water outlet holes are also provided on the injection rod body, and both the water inlet holes and the water outlet holes are communicated with the long hole.

[0004] During the implementation of this application, it is found that there are the following problems with this technology: When the injection rod body and the injection head are connected in the above patent document, although the oil pipe will be communicated with the oil storage cavity, there may be gaps, resulting in the leakage of lubricating oil into the annular cavity. After a long time, more lubricating oil will accumulate, resulting in more lubricating oil flowing out when the injection rod body and the injection head are disassembled later, and the sealing performance at the connection between the injection rod body and the injection head is poor.

[0005] Therefore, an automatic oiling device for a vacuum injection rod of a battery frame is proposed. Content of the Utility Model

An external thread section 15 is provided on the outer surface of the right end of the injection rod body 1. A connecting cylinder 24 is fixedly connected to the left side surface of the injection head 2, and the outer surface of the right end of the injection rod body 1 is inserted into the inner surface of the connecting cylinder 24. An internal thread section 25 is provided on the inner side wall of the connecting cylinder 24 close to the external thread section 15. An annular rubber pad two 26 is adhesively bonded to the inner side wall of the connecting cylinder 24 close to the injection head 2. A deformation hole 27 is opened inside the annular rubber pad two 26. The number of deformation holes 27 is several, and several deformation holes 27 are evenly arranged inside the annular rubber pad two 26. Specifically, when connecting the injection rod body 1 and the injection head 2, the left end of the injection rod body 1 is rotated and inserted into the inside of the connecting cylinder 24. The cooperation of the internal thread section 25 and the external thread section 15 can connect the injection rod body 1 and the injection head 2. When the external thread section 15 is rotated and inserted into the inside of the connecting cylinder 24, it will exert a little extrusion on the annular rubber pad two 26, and the deformation hole 27 can provide a certain deformation space for the deformation of the annular rubber pad two 26, thereby improving the sealing performance at the connection between the injection rod body 1 and the injection head 2.

[0025] Refer to Figures 1-4 , An oil pipe 13 is installed inside the injection rod body 1. An electromagnetic valve 14 is installed at the oil inlet hole at the left end of the oil pipe 13. An annular clamping groove 28 is opened on the left side surface of the injection head 2. The outer surface of the right end of the oil pipe 13 is inserted into the inner surface of the annular clamping groove 28. An annular rubber pad one 17 is adhesively bonded to the outer surface of the end of the oil pipe 13 extending into the annular clamping groove 28. An oil storage cavity 21 is provided inside the injection head 2, and the inner cavity at the right end of the oil pipe 13 is communicated with the oil storage cavity 21. Specifically, when the injection rod body 1 is connected to the injection head 2, the annular rubber pad one 17 on the oil pipe 13 will also abut against the inner wall of the annular clamping groove 28, further improving the sealing performance at the connection between the injection rod body 1 and the injection head 2. Compared with the injection rod in CN210789141U, the sealing performance at the connection between the injection rod body 1 and the injection head 2 can be improved through the cooperation of the above structures.

[0026] Refer to Figures 1-4 , A number of oil outlet holes 22 are opened on the outer side surface of the injection head 2. A flow sensor 23 is installed on the inner wall of the oil outlet hole 22. The flow sensor 23 and the electromagnetic valve 14 are electrically connected to the controller of the fuel tank through a cable arranged inside the injection rod body 1. Specifically, the controller in the fuel tank uses a single-chip microcomputer as the main control chip, and its model is STC89C51. The flow sensor 23 can be used to monitor the flow rate of the lubricating oil passing through the oil outlet hole 22 and feed the data back to the controller of the fuel tank. When the flow rate is insufficient, the controller will control to open the electromagnetic valve 14 and input lubricating oil into the oil pipe 13 to achieve automatic oil feeding.

Specifically, cooling water can be introduced through the water inlet holes 11. The cooling water will fill the inside of the injection rod body 1 to cool the injection rod, and finally flow out from the water outlet pipe connected to the water outlet holes 12, effectively reducing the temperature of the injection rod.

[0029] When using this device, first connect to an external power supply. The flow sensor 23 can monitor the flow rate of the lubricating oil passing through the oil outlet hole 22 and feed the data back to the controller of the fuel tank. When the flow rate is insufficient, the controller will control the solenoid valve 14 to open and start the oil pump in the fuel tank to input lubricating oil into the oil pipe 13 to achieve automatic oil feeding.

[0030] When connecting the injection rod body 1 and the injection head 2, the left end of the injection rod body 1 is rotated and inserted into the inside of the connecting cylinder 24. The cooperation of the internal thread section 25 and the external thread section 15 can connect the injection rod body 1 and the injection head 2.

At the same time, the annular rubber pad one 17 on the oil pipe 13 will also abut against the inner wall of the annular card slot 28, further improving the sealing performance at the connection between the injection rod body 1 and the injection head 2. Compared with the injection rod in CN210789141U, the sealing performance at the connection between the injection rod body 1 and the injection head 2 can be improved through the cooperation of the above structures.
