[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4 This utility model provides a technical solution: an easy-to-install bearing bush, including an upper bearing body 1, a lower bearing body 2 movably installed at the bottom end of the upper bearing body 1, and an installation and disassembly mechanism 3 provided at the top end of the lower bearing body 2;

[0022] The installation and disassembly mechanism 3 includes installation grooves 301. Two installation grooves 301 are formed at the top of the lower tile body 2. Supporting installation blocks 302 are fixedly installed on the inner walls of both sides of the two installation grooves 301. Connecting springs 303 are fixedly installed on the adjacent sides of the supporting installation blocks 302. Connecting installation plates 304 are fixedly installed on the side of the connecting springs 303 away from the supporting installation blocks 302. Disassembly and assembly fixing connecting rods 305 are fixedly installed on the opposite sides of the connecting installation plates 304. Disassembly and assembly fixing connecting holes 306 are formed on both sides of the lower tile body 2. The disassembly and assembly fixing connecting rods 305 are movably connected inside the disassembly and assembly fixing connecting holes 306. The bottom end of the upper tile body 1 is fixedly installed with... Two mounting connecting blocks 307 are installed, and mounting connecting brackets 308 are fixedly installed at the bottom of the two mounting connecting blocks 307. The mounting connecting brackets 308 at the bottom of the mounting connecting blocks 307 slowly approach the connecting mounting plate 304. As the mounting connecting brackets 308 gradually approach and contact the connecting mounting plate 304, the outer wall of the mounting connecting brackets 308 begins to squeeze the connecting mounting plate 304. After being squeezed by the mounting connecting brackets 308, the connecting mounting plate 304 overcomes the elastic force of the connecting spring 303 and moves to both sides inside the mounting groove 301, so that the mounting connecting brackets 308 are inserted into the connecting mounting plate 304, and the upper tile body 1 and the lower tile body 2 are installed and connected.

[0023] The lower oil groove 4 is provided at the top of the inner side of the lower bearing 2, and the upper oil groove 5 is provided at the bottom of the inner side of the upper bearing 1. The oil filling hole 6 is provided at the top of the upper bearing 1. The oil filling hole 6 has an internal thread 7. A sealing cover 8 is movably installed inside the oil filling hole 6. The outer end of the sealing cover 8 is threaded with an external thread 9. The sealing cover 8 is threadedly connected to the oil filling hole 6. When the sealing cover 8 is opened, lubricating oil is injected through the oil filling hole 6 and then enters the lower oil groove 4 and the upper oil groove 5.

[0024] Working principle: Pick up the upper tile body 1 and align the two mounting connecting blocks 307 fixed at its bottom with the mounting groove 301 on the lower tile body 2. Slowly move the mounting connecting bracket 308 at the bottom of the mounting connecting block 307 closer to the connecting mounting plate 304. As the mounting connecting bracket 308 gradually approaches and contacts the connecting mounting plate 304, the outer wall of the mounting connecting bracket 308 begins to squeeze the connecting mounting plate 304. After being squeezed by the mounting connecting bracket 308, the connecting mounting plate 304 overcomes the elastic force of the connecting spring 303 and moves to both sides inside the mounting groove 301. The connecting spring 303 is compressed. When the mounting connecting bracket 308 continues to move downward until it falls completely into the mounting groove 301 and reaches the predetermined position, the connecting spring 303 rebounds under its own elastic restoring force, pushing the connecting mounting plate 304 to tightly lock the outer wall of the mounting connecting bracket 308. At the same time, the disassembly and fixing connecting rod 305 is inserted into the disassembly and fixing connecting socket 306. This further enhances the stability of the connection, thereby achieving a quick and stable connection between the upper bearing body 1 and the lower bearing body 2. When the bearing needs to be disassembled, the operator inserts their fingers or tools into the disassembly and fixing connection holes 306 on both sides of the lower bearing body 2 and pushes the disassembly and fixing connection rod 305. After the disassembly and fixing connection rod 305 is pushed, it drives the connecting mounting plate 304 to overcome the elastic force of the connecting spring 303 and move towards the inside of the mounting groove 301. The connecting spring 303 is compressed again. As the connecting mounting plate 304 moves, the clamping state between it and the mounting connecting bracket 308 is gradually released. When the connecting mounting plate 304 and the mounting connecting bracket 308 are completely separated, the upper bearing body 1 can be easily lifted from the lower bearing body 2 and removed, completing the disassembly operation. Open the sealing cover 8 and inject lubricating oil through the oil injection hole 6. The lubricating oil then enters the lower oil groove 4 and the upper oil groove 5, so that the lubricating oil can be evenly distributed on the contact surface of the bearing and the journal, playing a lubricating role.

[0025] Finally, it should be noted that the above content is only used to illustrate the technical solution of this utility model, and is not intended to limit the scope of protection of this utility model. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model do not depart from the essence and scope of the technical solution of this utility model.
