[0025] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0026] like Figure 1-3 As shown, the utility model provides a technical solution: a deep groove ball bearing with dustproof effect, comprising an inner ring 1 and an outer ring 2, the inner ring 1 is arranged inside the outer ring 2, a plurality of steel balls 5 are arranged between the inner ring 1 and the outer ring 2, a retaining frame 6 is arranged between the inner ring 1 and the outer ring 2, the retaining frame 6 is sleeved on the surfaces of the plurality of steel balls 5, a dustproof device 3 is arranged between the inner ring 1 and the outer ring 2, a protective device 4 is arranged on one side of the outer ring 2, the dustproof device 3 comprises a groove 31 opened on one side of the inner ring 1, a threaded groove 32 is opened on the inner wall of the groove 31, a round hole block 33 is slidably connected to the inner wall of the groove 31, a bolt 35 is arranged inside the round hole block 33, the surface of the bolt 35 is threadedly connected to the inner wall of the threaded groove 32, a sealing ring 34 is fixedly connected to one side of the round hole block 33, the sealing ring 34 is arranged between the inner ring 1 and the outer ring 2, and the sealing ring 3 The surface of 4 fits with the surface of the inner ring 1, and the surface of the sealing ring 34 fits with the inner wall of the outer ring 2. By setting the dustproof device 3, the sealing ring 34 is first moved manually, so that the sealing ring 34 drives the circular hole block 33 to move. When the circular hole block 33 moves to the internal position of the insertion groove 31, the inner wall of the thread groove 32 coincides with the inner wall of the circular hole block 33. At this time, the bolt 35 is rotated by a tool to make the bolt 35 rotate into the internal position of the circular hole block 33 and the thread groove 32 to fix the circular hole block 33 and the sealing ring 34, so that the sealing ring 34 is located between the inner ring 1 and the outer ring 2 and fills the gap between the two to prevent the entry of external dust, thereby reducing the external dust and debris falling between the inner ring 1 and the outer ring 2, causing the steel ball 5 to be blocked or stuck during rotation, thereby improving the use efficiency and internal cleanliness of the bearing.

[0027] Specifically, Figure 2 and Figure 3As shown, a receiving groove 36 is provided on one side of the circular hole block 33, and the size and shape of the inner wall of the receiving groove 36 are adapted to the size and shape of the nut of the bolt 35. By providing the receiving groove 36, the nut of the bolt 35 can be accommodated in the receiving groove 36, thereby reducing the situation where the nut of the bolt 35 protrudes from the surface of the inner ring 1 and affects normal use. A wear-resistant ring 37 is fixedly connected to one side of the sealing ring 34, and the surface of the wear-resistant ring 37 is annular. By providing the wear-resistant ring 37, the wear-resistant ring 37 can increase the friction durability between the sealing ring 34 and the outer ring, thereby improving the service life of the sealing ring 34. A plurality of reinforcing ribs 38 are fixedly connected to one side of the sealing ring 34, and the plurality of reinforcing ribs 38 are fixedly connected to the inner wall of the wear-resistant ring 37. By providing the reinforcing ribs 38, the reinforcing ribs 38 can increase the strength of the sealing ring 34, thereby reducing the shaking of the sealing ring 34 during use.

[0028] Specifically, Figure 4 As shown, the protective device 4 includes a sleeve 41, which is sleeved on the surface of the outer ring 2, and the inner wall of the sleeve 41 is fixedly connected with a cylinder 42, and the surface of the cylinder 42 is slidably connected to the inner wall of the inner ring 1. By setting the protective device 4, the sleeve 41 is first manually moved so that the sleeve 41 drives the cylinder 42 to move. When the sleeve 41 moves to a position sleeved on the surface of the outer ring 2, the cylinder 42 is inserted into the inner ring 1, so that the sleeve 41 and the cylinder 42 are respectively sleeved on the outer ring 2 and the inner ring 1 to intercept external objects, and at the same time protect the outer ring 2 and the inner ring 1, thereby reducing the outer ring 2 and the inner ring 1 from falling off when being carried, causing damage to the outer ring 2 or the inner ring 1 and affecting the use, and improving the safety of carrying the inner ring 1 and the outer ring 2.

[0029] Specifically, Figure 4 As shown, a plurality of rubber pads 43 are fixedly connected to the surface of the sleeve 41, and the surface of the rubber is arc-shaped. By arranging the rubber pads 43, the rubber pads 43 can separate the sleeve 41 from external objects, reduce the impact force caused by the outer ring 2 falling, and further improve the protection effect on the outer ring 2 or the inner ring 1. A plurality of anti-slip strips 44 are fixedly connected to the inner wall of the cylinder 42, and the plurality of anti-slip strips 44 are arranged at equal distances. By arranging the anti-slip strips 44, the anti-slip strips 44 can increase the friction between the hand and the inner wall of the cylinder 42, so that the person can insert the hand into the cylinder 42 to transmit the sleeve 41 more stably, thereby improving the convenience of manually stripping the sleeve 41.

[0030] The working principle of the utility model is:

[0031] S1. First, manually move the sealing ring 34 so that the sealing ring 34 drives the circular hole block 33 to move. When the circular hole block 33 moves to the internal position of the insertion groove 31, the inner wall of the thread groove 32 coincides with the inner wall of the circular hole block 33. At this time, the bolt 35 is rotated by a tool so that the bolt 35 is rotated into the internal position of the circular hole block 33 and the thread groove 32 to fix the circular hole block 33 and the sealing ring 34. Then, the sealing ring 34 is located between the inner ring 1 and the outer ring 2 and fills the gap between the two to prevent the entry of external dust, thereby completing the dustproof treatment of the bearing.

[0032] S2. First, manually move the sleeve 41 so that the sleeve 41 drives the cylinder 42 to move. When the sleeve 41 moves to the position on the surface of the outer ring 2, the cylinder 42 is inserted into the inner ring 1, so that the sleeve 41 and the cylinder 42 are respectively on the outer ring 2 and the inner ring 1 to intercept external objects and protect the outer ring 2 and the inner ring 1 at the same time.

[0033] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0034] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
