[0032] The following is in conjunction with the appendix Figure 1 -Appendix Figure 7 The present invention will be described in further detail below.

[0033] This utility model discloses a liquid lubricating oil anti-leakage structure for a driven guide roller bearing housing. (Refer to...) Figures 1-7 It includes a driven guide roller 1, a bearing housing 2 and a bearing 3. The driven guide roller 1 extends to the inside of the bearing housing 2. The bearing 3 is fixedly connected to the inside of the bearing housing 2. There are through covers 4 and blind covers 5 on both sides of the bearing housing 2. Both through covers 4 and blind covers 5 are in contact with the bearing housing 2. A leak-proof mechanism 6 is provided on the outside of the driven guide roller 1.

[0034] The anti-leakage mechanism 6 includes an anti-leakage ring 61, which is fixedly connected to the outside of the driven guide roller 1. The anti-leakage ring 61 is located inside the through cover 4. A top frame 62 and a bottom frame 63 are provided outside the driven guide roller 1. The top frame 62 is located on top of the bottom frame 63 and fits against the bottom frame 63. Both the top frame 62 and the bottom frame 63 fit against the outside of the driven guide roller 1. A cotton layer 64 is fixedly connected inside the top frame 62 and the bottom frame 63.

[0035] Both the top frame 62 and the bottom frame 63 are provided with observation ports 65, which are arranged at equal intervals on the top frame 62 and the bottom frame 63 respectively. The anti-leak ring 61 outside the driven guide roller 1 does not contact the inner diameter surface of the cover 4. In this way, when the lubricating oil inside the bearing seat 2 drips onto the outer diameter of the shaft through the groove of the cover 4, the oil is blocked by the anti-leak ring 61 and flows back into the bearing seat 2, ensuring that the lubricating oil does not leak out. In addition, if the anti-leak ring 61 is damaged or other extreme situations cause lubricating oil leakage, the leaked oil enters the space formed by the top frame 62 and the bottom frame 63 and is absorbed by the cotton layer 64. The user can quickly judge the oil leakage situation by observing the changes in the cotton layer 64 through the observation port 65, thereby further improving the anti-leak safety performance.

[0036] The driven guide roller 1 has a slot 66. The top frame 62 and the bottom frame 63 are both fixedly connected to the insert rod 67. The insert rod 67 extends into the slot 66 and matches the slot 66. After the insert rod 67 is inserted into the slot 66, it can provide a limit for the top frame 62 and the bottom frame 63. The bottom frame 63 is fixedly connected to the first rectangular plate 68, and the top frame 62 is fixedly connected to the second rectangular plate 69. The second rectangular plate 69 is set on the top of the first rectangular plate 68 and fits against the first rectangular plate 68. After the first rectangular plate 68 and the second rectangular plate 69 fit against each other, it is easy to improve the stability of the top frame 62 and the bottom frame 63 after installation.

[0037] A limiting plate 691 is fixedly connected to the top of the first rectangular plate 68. The limiting plate 691 passes through the second rectangular plate 69. A locking block 692 is slidably connected inside the limiting plate 691. The locking block 692 extends out of the limiting plate 691. The bottom of the locking block 692 is in contact with the top of the second rectangular plate 69. After the locking block 692 extends out of the limiting plate 691, the first rectangular plate 68 and the second rectangular plate 69 remain in contact. A spring 693 is fixedly connected inside the limiting plate 691. The spring 693 is fixedly connected to one side of the locking block 692. The spring 693 exerts an elastic force on the locking block 692.

[0038] A fixing rod 694 is provided on one side of the end cap 5. The fixing rod 694 passes through the end cap 5, the bearing 3 and the through cap 4 in sequence. A fixing ring 695 is provided on one side of the through cap 4. The fixing rod 694 passes through the fixing ring 695 and is connected to the fixing ring 695 by threads. The fixing ring 695 fits against one side of the through cap 4. After the fixing ring 695 is tightened outside the fixing rod 694, the end cap 5 and the through cap 4 fit tightly against both sides of the bearing seat 2. The driven guide roller 1 passes through the through cap 4 and the bearing 3 in sequence. The bearing 3 is fixedly connected to the outside of the driven guide roller 1. The bearing 3 is installed on the outside of the driven guide roller 1 so that when the driven guide roller 1 rotates, it will not affect the bearing seat 2.

[0039] In actual operation, after inserting the fixing rod 694 from one side of the end cap 5 to the through cap 4, tighten the fixing ring 695 on the outside of the fixing rod 694 to fix the end cap 5 and the through cap 4 tightly against both sides of the bearing seat 2. The bearing seat 2 is filled with lubricating oil. When this device is working, the anti-leakage ring 61 on the outside of the driven guide roller 1 does not contact the inner diameter surface of the through cap 4. In this way, when the lubricating oil inside the bearing seat 2 drips onto the outer diameter of the shaft through the groove of the through cap 4, the anti-leakage ring 61 blocks the oil and flows back into the bearing seat 2, ensuring that the lubricating oil will not leak out. However, if extreme situations such as the damage of the anti-leakage ring 61 cause the lubricating oil to leak, the lubricating oil will enter the space formed by the top frame 62 and the bottom frame 63 and be absorbed by the cotton layer 64. The cotton layer 64 will change color after absorbing the lubricating oil. The user can quickly judge the lubricating oil leakage during operation by observing the extension change of the inner cotton layer 64 through the observation port 65, and thus take timely action.

[0040] If the cotton layer 64 has absorbed lubricating oil and needs to be replaced, simply pinch the locking block 692 into the limiting plate 691 to remove the limiting plate 691 from the second rectangular plate 69, thus separating the top frame 62 and the bottom frame 63. When replacing the top frame 62 and the bottom frame 63 with new ones, align the insert rods 67 on the top frame 62 and the bottom frame 63 with the two ends of the slot 66 and insert them. At this time, the locking block 692 on the limiting plate 691 will be squeezed and enter the limiting plate 691. When the locking block 692 moves to the other side of the second rectangular plate 69, it will be pushed out by the elastic force of the spring 693. This completes the quick assembly of the top frame 62 and the bottom frame 63. Accordingly, the installation and removal process of the top frame 62 and the bottom frame 63 is simple and convenient, which is conducive to users to quickly learn how to operate and replace them, and makes them more flexible to use.

[0041] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
