[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-4 The utility model provides an embodiment: a split bolt that is easy to maintain, including a supporting device 3, a receiving device 2 is slidably sleeved on the top of the supporting device 3, and a covering device 1 is threadedly inserted on the top of the receiving device 2. The covering device 1 includes a covering ring 4, a plastic ring 5 and a threaded sleeve 6. The plastic ring 5 is fixedly installed on the outer ring of the covering ring 4, and the threaded sleeve 6 is fixedly installed on the bottom end of the covering ring 4. The supporting device 3 includes a screw body 12 and a screw head 13, and the screw body 12 is fixedly installed at the bottom end center of the screw head 13.

[0021] The storage device 2 includes a first support ring 7, a second support ring 8, a support bottom ring 9, a guide tube 10 and a sealing head 11. The second support ring 8 and the first support ring 7 are fixedly installed on the top of the support bottom ring 9, and the first support ring 7 is located in the inner ring of the second support ring 8. The guide tube 10 is fixedly installed inside the first support ring 7 and the second support ring 8, and the sealing head 11 is threadedly sleeved on the end of the guide tube 10 away from the second support ring 8.

[0022] The screw body 12 is slidably inserted into the inner center of the support bottom ring 9, and the threaded sleeve 6 is threadedly inserted into the inner ring of the first support ring 7, so that lubricating oil can be retained between the threaded sleeve 6 and the first support ring 7.

[0023] The top of the inner wall of the first support ring 7 is provided with a thread to facilitate the butt-jointing installation of the threaded sleeve 6 and the first support ring 7 .

[0024] The outer ring of the flow guide tube 10 and the inner ring surface of the plugging head 11 are both provided with threads, so as to facilitate the removal or reinstallation of the plugging head 11 from the outer ring of the flow guide tube 10 .

[0025] A sealing ring is fixedly mounted on the bottom end of the screw head 13 to prevent oil leakage from the bottom end of the supporting bottom ring 9.

[0026] Working principle: When in use, first slide the screw body 12 into the inside of the support bottom ring 9 until the screw body 12 is threadedly installed on the external equipment, so that the screw head 13 can drive the support bottom ring 9 to be fastened to the surface of the external equipment. At the same time, when the screw head 13 is fastened to the support bottom ring 9, the sealing ring at the bottom end of the screw head 13 can be driven to be fastened to the support bottom ring 9. Then, the covering ring 4 can be installed above the second support ring 8 until the threaded sleeve 6 is threadedly adapted to the first support ring 7, so that the first support ring 7 and the threaded sleeve 6 wrap the outer periphery of the screw head 13. Then, when the threaded sleeve 6 and the first support ring 7 are aligned and adapted, the plastic ring 5 can be driven. The second support ring 8 fits together, so that the plastic ring 5 and the second support ring 8 can protect the periphery of the first support ring 7 and the threaded sleeve 6 to prevent the threaded sleeve 6 and the first support ring 7 from premature aging. At the same time, when the threaded sleeve 6 and the first support ring 7 are screwed and tightened, the sealing head 11 can be screwed off from the outer ring of the guide tube 10, and then the external lubricating oil is poured into the interior of the guide tube 10. The guide tube 10 is connected to the interior of the first support ring 7, so that the lubricating oil can enter between the threaded sleeve 6 and the first support ring 7, so that the lubricating oil can be wrapped on the outer ring of the screw head 13. Subsequently, when the threaded sleeve 6 and the first support ring are tightened, the sealing head 11 can be screwed off from the outer ring of the guide tube 10, and then the external lubricating oil can be poured into the interior of the guide tube 10. The lubricating oil can enter between the threaded sleeve 6 and the first support ring 7, so that the lubricating oil can be wrapped on the outer ring of the screw head 13. After the lubricating oil is poured between the threaded sleeve 6 and the first support ring 7, the sealing head 11 can be installed on the outer ring of the guide tube 10 again to prevent the lubricating oil from flowing out from the inside of the guide tube 10, thereby completing the lubrication and protection of the screw head 13. When the lubricating oil between the threaded sleeve 6 and the first support ring 7 needs to be replaced, the cover ring 4 can be screwed and rotated to make the threaded sleeve 6 disengage from the first support ring 7, so that the threaded sleeve 6 and the first support ring 7 are separated, so that the lubricating oil between the threaded sleeve 6 and the first support ring 7 can flow out, completing the lubricating oil release work, and then repeat the above steps to pour the lubricating oil from the inside of the guide tube 10 to the threaded sleeve 6 and the interior of the first support ring 7, so that the screw head 13 can be lubricated and protected again. When the device is in use, when the threaded sleeve 6 is screwed to the outer ring of the first support ring 7, the plastic ring 5 and the second support ring 8 can be driven to cooperate, so that the threaded sleeve 6 and the first support ring 7 can be protected, and the guide tube 10 and the first support ring 7 are interconnected, so that the guide tube 10 can transport lubricating oil to the interior of the first support ring 7. At the same time, the threaded sleeve 6 and the first support ring 7 are screwed together, so that the lubricating oil can remain between the threaded sleeve 6 and the first support ring 7, so that the lubricating oil can lubricate and protect the screw head 13, and the work is completed.

[0027] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
