[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0024] like Figures 1-5 As shown, the internally spiral-threaded easy-to-disassemble power steering pump housing includes a power steering pump housing 1 with a connecting groove 2 on the top, and the connecting groove 2 is provided with a connector for connecting equipment.
[0025] The connecting component includes a connecting ring 3 disposed inside the connecting groove 2, and the inner sidewall of the connecting ring 3 is machined with an internal thread 4; a plurality of fixing blocks 5 arranged in a ring array are installed on the outer side of the top of the connecting ring 3, and a fixing groove 6 is opened on the top of the booster pump housing 1 corresponding to the fixing block 5, the fixing groove 6 is connected to the connecting groove 2, and the fixing block 5 is disposed inside the fixing groove 6.
[0026] When in use, the staff connects to the equipment through the internal thread 4 in the connecting ring 3. The connection method of the internal thread 4 can effectively realize the convenient disassembly and assembly of the booster pump housing 1.
[0027] Meanwhile, when the internal thread 4 is worn and cannot be precisely engaged, the worker rotates the disassembly fixing bolt 7 to separate it from the booster pump housing 1, so that the top of the connecting ring 3 is not restricted. Then, the worker rotates the disassembly positioning bolt 10 to separate it from the booster pump housing 1, so that the bottom of the connecting ring 3 is not restricted. In this way, the connecting ring 3 with worn internal thread 4 can be disassembled and replaced.
[0028] When replacing the connecting ring 3, the workers place the connecting ring 3 inside the booster pump housing 1 and limit the top of the connecting ring 3 by the engagement of the fixing block 5 and the fixing groove 6 to prevent the connecting ring 3 from rotating. Then, the connecting ring 3 is assembled and fixed by the fixing bolt 7 and the positioning bolt 10 to ensure the stability of the connecting ring 3. With the replaceable connecting ring 3, it is not necessary to replace the entire booster pump housing 1, which can greatly reduce maintenance time and cost and achieve the effect of reducing the cost of use.
[0029] While using the above structure to limit the top of the connecting ring 3, it is also necessary to ensure the stability of the bottom of the connecting ring 3 to avoid pressure imbalance. Figures 3-5 As shown, a plurality of positioning plates 8 arranged in a ring array are installed at the bottom end of the connecting ring 3, and a positioning groove 9 is provided on one side of the booster pump housing 1 corresponding to the positioning plate 8. The positioning groove 9 is connected to the connecting groove 2. The positioning plate 8 is located inside the positioning groove 9. A positioning bolt 10 is provided on the side of the positioning plate 8 away from the positioning groove 9. The positioning bolt 10 passes through the positioning plate 8 and extends into the booster pump housing 1. The positioning bolt 10 is threadedly connected to the booster pump housing 1.
[0030] When assembling the connecting ring 3, the operator can accurately insert the connecting ring 3 into the booster pump housing 1 by engaging the positioning block with the positioning groove 9, thereby achieving the effect of limiting the bottom end of the connecting ring 3. Then, the positioning bolt 10 is used to fix and limit the positioning plate 8, ensuring the connection stability between the connecting ring 3 and the booster pump housing 1.
[0031] When assembling the power booster pump housing 1 and connecting it to the equipment, to avoid leakage, it is necessary to enhance the sealing between the power booster pump housing 1 and the equipment, such as... Figures 1-3 As shown, the top of the power booster pump housing 1 is provided with a sealing ring 11, and an annular groove 12 is opened on one side of the top of the power booster pump housing 1 corresponding to the sealing ring 11. The sealing ring 11 is located inside the annular groove 12, and the annular groove 12 is located outside the connecting groove 2 and multiple fixing grooves 6. Multiple limiting posts 13 arranged in a ring array are installed at the bottom of the sealing ring 11, and a limiting groove 14 is opened on one side of the top of the power booster pump housing 1 corresponding to the limiting posts 13. The bottom end of the limiting post 13 extends into the limiting groove 14, and the limiting groove 14 is connected to the annular groove 12. By installing the sealing ring 11 on the top of the power booster pump housing 1, the sealing ring 11 can fit tightly with the equipment when the power booster pump housing 1 is connected to the equipment, thereby enhancing the sealing performance between the power booster pump housing 1 and the equipment and preventing leakage. At the same time, the locking of the limiting posts 13 and the limiting groove 14 achieves the effect of limiting and fixing the sealing ring 11, preventing the sealing ring 11 from rotating and ensuring the performance of the sealing ring 11.
