Description

Technical Field

[0001] This utility model relates to the field of flange technology, specifically a transmission box flange. Background Technology

[0002] As a crucial connecting component in mechanical equipment, the stability and durability of the transmission box flange have a vital impact on the overall performance of the equipment. In practical applications, flanges are typically secured with bolts to ensure a tight connection between them and other components.

[0003] However, when flanges are in use, they are exposed to the air for extended periods. The air is filled with oxygen and moisture, which can react chemically with metals under certain conditions. For the bolts on the flanges, being directly exposed to the air and often lacking sufficient protection, they are highly susceptible to oxidation. Over time, an oxide layer gradually forms on the bolt surface, commonly known as "rust." Rusting not only affects the bolt's appearance, but more importantly, it creates numerous tiny voids inside the bolt. These voids weaken the bolt's mechanical strength and may cause deformation or breakage under pressure. The corrosion and rusting of the bolts directly leads to instability in their fixing effect on the flange. A previously tight connection may loosen due to bolt corrosion, affecting the overall stability and performance of the transmission box. In extreme cases, loosening of the flange may even lead to equipment malfunction or safety accidents. Therefore, we propose a transmission box flange to address these issues. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a transmission box flange, which solves the problems mentioned in the background section.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0008] A transmission box flange includes a flange body with multiple mounting holes for bolts to movably contact. The flange body has two cavities. A positioning rod is welded to the inner wall of one side of each cavity, and a locking pin is slidably connected to the positioning rod. A spring is fixedly connected between the end of the locking pin and the inner wall of the corresponding cavity, and the spring is movably sleeved on the corresponding positioning rod. A ball is embedded in the other end of the locking pin. A connecting block is welded to one side of the locking pin. T-shaped rods are provided on both sides of the flange body, with the ends of the T-shaped rods extending into the corresponding cavities and fixedly connected to one side of the connecting block. A sealing ring is movably contacted on one side of the flange body. Multiple circular grooves are annularly formed on one side of the sealing ring, and these grooves engage with corresponding bolts. Two mounting rods are fixedly connected to one side of the sealing ring. One side of each mounting rod is an inclined surface with a groove that engages with a corresponding locking pin. The inclined surface also engages with a corresponding ball.

[0009] Furthermore, a rectangular hole is provided on the inner wall of the other side of the cavity, and the inner wall of the rectangular hole does not contact the outer side of the corresponding mounting rod.

[0010] Furthermore, a limiting groove is formed on one side of the flange body, and a limiting ring is fitted on the limiting groove. One side of the limiting ring is fixedly connected to one side of the sealing cover ring.

[0011] Furthermore, a guide hole is provided on one side of the inner wall of the cavity, and the inner wall of the guide hole is slidably connected to the outer side of the corresponding T-shaped rod.

[0012] Furthermore, a limiting hole is provided on the locking pin, and the locking pin is slidably connected to the corresponding positioning rod through the limiting hole.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, the present invention provides a transmission box flange, which has the following advantages:

[0015] This invention uses bolts to fix the flange body to the place of use. Then, the mounting rod on the sealing cover ring is inserted into the cavity through the rectangular hole. The inclined surface of the mounting rod contacts and presses against the corresponding ball. Under the action of the pressing force, the ball drives the locking pin to slide on the corresponding positioning rod. During the movement, the locking pin compresses the corresponding spring. When the locking groove aligns with the corresponding ball, the spring, which is in a compressed state, returns to its original state. The spring drives the corresponding locking pin to engage with the locking groove, thereby fixing the sealing cover ring to the flange body. At the same time, the circular groove on the sealing cover ring engages with the bolt, and the sealing cover ring seals and protects the bolt, preventing the bolt from being exposed and rusting.

[0023] Example

[0024] like Figure 1-5As shown in the figure, an embodiment of the present invention provides a transmission box flange, including a flange body 1. The flange body 1 has multiple mounting holes 2, with bolts 3 movably contacting the mounting holes 2. The flange body 1 has two cavities 4. A positioning rod 5 is welded to the inner wall of one side of each cavity 4. A locking pin 6 is slidably connected to the positioning rod 5. A spring 7 is fixedly connected between the end of the locking pin 6 and the inner wall of the corresponding cavity 4. The spring 7 is movably sleeved on the corresponding positioning rod 5. A ball bearing 8 is embedded at the other end of the locking pin 6. A connecting block 9 is welded to one side of the locking pin 6. T-shaped rods 10 are provided on both sides of the flange body 1. The ends of the T-shaped rods 10 extend into the corresponding cavities 4 and are fixedly connected to one side of the connecting block 9. A sealing cover ring 11 movably contacts one side of the flange body 1. A plurality of circular grooves 12 are annularly formed on one side of the sealing cover ring 11. The circular grooves 12 engage with the corresponding bolts 3. Two mounting holes 3 are fixedly connected to one side of the sealing cover ring 11. Mounting rod 13 has an inclined surface on one side, with a groove 14 on the inclined surface. The groove 14 engages with the corresponding locking pin 6, and the inclined surface cooperates with the corresponding ball bearing 8. The flange body 1 is fixed to the place of use by bolts 3. Then, the mounting rod 13 on the sealing cover ring 11 is inserted into the cavity 4 through the rectangular hole 15. The inclined surface of the mounting rod 13 contacts and presses against the corresponding ball bearing 8. Under the action of the pressing force, the ball bearing 8 drives the locking pin 6 to slide on the corresponding positioning rod 5. During the movement, the locking pin 6 compresses the corresponding spring 7. When the groove 14 aligns with the corresponding ball bearing 8, the spring 7, which is in a compressed state, returns to its original state. The spring 7 drives the corresponding locking pin 6 to engage with the groove 14, thereby fixing the sealing cover ring 11 to the flange body 1. At the same time, the circular groove 12 on the sealing cover ring 11 is engaged with the bolt 3. The sealing cover ring 11 seals and protects the bolt 3, preventing the bolt 3 from being exposed and rusting.

[0025] In some embodiments, a rectangular hole 15 is provided on the inner wall of the other side of the cavity 4, and the inner wall of the rectangular hole 15 does not contact the outer side of the corresponding mounting rod 13.

[0026] In some embodiments, a limiting groove 16 is provided on one side of the flange body 1, and a limiting ring 17 is fitted on the limiting groove 16. One side of the limiting ring 17 is fixedly connected to one side of the sealing cover ring 11. The setting of the limiting ring 17 plays a limiting role.

[0027] In some embodiments, a guide hole is provided on one side of the inner wall of the cavity 4, and the inner wall of the guide hole is slidably connected to the outer side of the corresponding T-shaped rod 10.

[0028] In some embodiments, a limiting hole is provided on the locking pin 6, and the locking pin 6 is slidably connected to the corresponding positioning rod 5 through the limiting hole. The positioning rod 5 serves as a positioning tool.

[0029] Working principle or structural principle: During use, the sealing cover ring 11 is separated from the flange body 1. The flange body 1 is fixed to the place of use by bolts 3. Then, the mounting rod 13 on the sealing cover ring 11 is inserted into the cavity 4 through the rectangular hole 15. The inclined surface of the mounting rod 13 contacts and presses against the corresponding ball 8. Under the action of the pressing force, the ball 8 drives the locking pin 6 to slide on the corresponding positioning rod 5. During the movement, the locking pin 6 compresses the corresponding spring 7. When the locking groove 14 aligns with the corresponding ball 8, the spring 7, which is in a compressed state, returns to its original position. 7 drives the corresponding locking pin 6 to engage with the locking groove 14, thereby fixing the sealing cover ring 11 to the flange body 1. At the same time, the circular groove 12 on the sealing cover ring 11 engages with the bolt 3, and the sealing cover ring 11 seals and protects the bolt 3, preventing the bolt 3 from being exposed and rusting. When disassembling, pull the T-shaped rod 10. The T-shaped rod 10 drives the corresponding locking pin 6 to move through the connecting block 9. The locking pin 6 slides on the corresponding positioning rod 5 and compresses the spring 7, causing the locking pin 6 to separate from the corresponding locking groove 14. Then, move the sealing cover ring 11 to remove the sealing cover ring 11.
