Description

Technical Field

[0001] The utility model belongs to the field of booster fans, and particularly relates to a booster fan with a shaft end sealing structure. Background Art

[0002] A booster fan is a device that can effectively increase air flow and air pressure, and is widely used in industrial production, ventilation and exhaust, environmental protection and other fields. The shaft end of the booster fan is a very important part, and its working state directly affects the performance and stability of the entire fan. First of all, the design of the shaft end of the booster fan needs to have a certain strength and stiffness to withstand the inertial force and inertial moment generated during the high-speed rotation of the fan. At the same time, the shaft end also needs to have good wear resistance and corrosion resistance to ensure long-term stable operation. Therefore, strict control is required in the material selection and processing technology of the shaft end to ensure that it meets the engineering requirements. In the prior art, the device does not have a sealing mechanism, and it is inconvenient to seal the device, resulting in inconvenient use of the device. Therefore, it is necessary to improve the prior art. Summary of the Invention

[0003] The purpose of the utility model is to provide a booster fan with a shaft end sealing structure, which solves the problem that the device does not have a sealing mechanism, and it is inconvenient to seal the device, resulting in inconvenient use of the device.

[0004] To achieve the above purpose, the utility model provides a booster fan with a shaft end sealing structure, including a booster fan body and a rotating block. A shaft body is arranged inside the booster fan body. A sealing ring is in contact with the inside of the booster fan body. The shaft body is in contact with the inside of the sealing ring. A connecting sleeve is fixedly connected to the outside of the sealing ring. The connecting sleeve is in contact with the inside of the booster fan body. A fixing sleeve is in contact with the inside of the booster fan body. The sealing ring is in contact with the fixing sleeve. The shaft body is in contact with the inside of the fixing sleeve. The connecting sleeve is in contact with the fixing sleeve. A threaded groove is opened inside the booster fan body. The rotating block is in contact with the fixing sleeve. A screw rod is movably connected to the inside of the fixing sleeve. A limiting mechanism is arranged on the outside of the fixing sleeve. By moving the sealing ring, the connecting sleeve and the fixing sleeve to the designated positions inside the booster fan body, and then installing components such as the screw rod to the designated positions on the device, the components such as the sealing ring are limited, and thus the device is sealed, making the device convenient to use.

[0005] The principle of the present utility model is as follows: When in use, pull the handle to move towards the elastic sponge. The movement of the handle drives the movement of the connecting block, the movement of the connecting block drives the movement of the pulling block, the movement of the pulling block drives the movement of the sliding block, the movement of the sliding block drives the movement of the groove, the movement of the groove drives the movement of the ball, and the movement of the sliding block compresses the elastic sponge. After the sliding block moves to the specified position, move the sealing ring, connecting sleeve, and fixing sleeve to the specified position inside the booster fan body. Then move the rotating block, and the movement of the rotating block drives the annular groove and the screw rod to move towards the fixing sleeve. The screw rod moves and inserts into the fixing sleeve to contact the thread groove. Then rotate the rotating block, and the rotation of the rotating block drives the screw rod to rotate. The rotation of the screw rod and the thread groove undergo a threading movement, thereby causing the screw rod to generate a relative displacement. After the screw rod rotates to the specified position, the sealing ring and other components are limited, and thus the device is sealed, making the device easy to use;

[0006] When the screw rod needs to be limited, release the handle, and the elastic force of the elastic sponge pushes the sliding block to move. The movement of the sliding block drives the movement of the groove and the pulling block, the movement of the pulling block drives the movement of the connecting block and the handle, the movement of the groove drives the movement of the ball, and the sliding block moves into the annular groove, thereby limiting the screw rod and preventing the screw rod from loosening during long-term use.

[0007] The beneficial effects of the present utility model are as follows: In this solution, by designing components such as the sealing ring, connecting sleeve, fixing sleeve, thread groove, screw rod, and rotating block, move the sealing ring, connecting sleeve, and fixing sleeve to the specified position inside the booster fan body, and then install components such as the screw rod to the specified position on the device, thereby limiting the sealing ring and other components, and thus sealing the device, making the device easy to use. By designing components such as the annular groove, sliding block, sliding groove, guide rod, groove, and ball, by pulling the sliding block to the specified position, then installing components such as the screw rod and rotating block to the specified position, and then moving the sliding block into the annular groove, the screw rod is limited, preventing the screw rod from loosening during long-term use.

[0008] Further, a screw rod is threadedly connected inside the thread groove, and a rotating block is fixedly connected to one end of the screw rod away from the thread groove. By designing the rotating block, it can be used to drive the screw rod to rotate.

[0009] Further, the limiting mechanism includes an annular groove. An annular groove is formed inside the rotating block. A slider is slidably connected inside the annular groove. A sliding groove is formed inside the slider. A guide rod is slidably connected inside the sliding groove. A groove is formed inside the slider. An elastic sponge is arranged on the outer side of the guide rod. A connecting seat is fixedly connected to the fixed sleeve. A guide rod is fixedly connected inside the connecting seat. A sliding groove is formed inside the connecting seat. A slider is slidably connected inside the connecting seat. A pulling block is fixedly connected to the outer side of the slider. By pulling the slider to a specified position, then installing components such as the screw rod and the rotating block to the specified position, and then moving the slider into the annular groove, the screw rod can be limited, preventing the screw rod from loosening after long-term use.

[0010] Further, a ball is arranged inside the groove. The outer side of the ball contacts the guide rod. By designing the ball, the friction between the slider and the guide rod can be reduced.

[0011] Further, one end of the elastic sponge is fixedly connected to the slider, and the other end of the elastic sponge is fixedly connected to the connecting seat. By designing the elastic sponge, the slider has an elastic effect.

[0012] Further, a pulling block is slidably connected inside the sliding groove. A connecting block is fixedly connected to the pulling block. By designing the pulling block, it can be used to drive the slider to move.

The rotating block 8 is in contact with the fixing sleeve 5. The screw rod 7 is movably connected to the inside of the fixing sleeve 5. The limiting mechanism 9 is arranged on the outside of the fixing sleeve 5. By moving the sealing ring 3, the connecting sleeve 4 and the fixing sleeve 5 to the designated positions inside the booster fan body 1, and then installing components such as the screw rod 7 to the designated positions on the device, the sealing ring 3 and other components are limited, and thus the device is sealed, making the device easy to use.

[0022] As Figure 2 — Figure 5 shown, the limiting mechanism 9 includes the annular groove 91. The annular groove 91 is opened inside the rotating block 8. The slider 92 is slidably connected to the inside of the annular groove 91. The sliding groove 93 is opened inside the slider 92. The guide rod 94 is slidably connected to the inside of the sliding groove 93. The groove 95 is opened inside the slider 92. The ball 96 is arranged inside the groove 95. The outside of the ball 96 is in contact with the guide rod 94. By designing the ball 96, the friction between the slider 92 and the guide rod 94 can be reduced. The elastic sponge 97 is arranged on the outside of the guide rod 94. One end of the elastic sponge 97 is fixedly connected to the slider 92. The other end of the elastic sponge 97 is fixedly connected to the connecting seat 98. By designing the elastic sponge 97, the slider 92 has an elastic effect.

[0023] As Figure 2 — Figure 5As shown in the figure, a connecting seat 98 is fixedly connected to the fixed sleeve 5. A guide rod 94 is fixedly connected inside the connecting seat 98. A sliding groove 99 is formed inside the connecting seat 98. A pulling block 910 is slidably connected inside the sliding groove 99. A connecting block 911 is fixedly connected to the pulling block 910. By designing the pulling block 910, it can be used to drive the slider 92 to move. The connecting block 911 is slidably connected to the connecting seat 98. A handle 912 is fixedly connected to the connecting block 911. By designing the handle 912, it can be used to drive the connecting block 911 to move. A slider 92 is slidably connected inside the connecting seat 98. A pulling block 910 is fixedly connected to the outer side of the slider 92. By pulling the slider 92 to a specified position, then installing components such as the screw rod 7 and the rotating block 8 to the specified positions, and then moving the slider 92 into the annular groove 91, the screw rod 7 is thus limited, preventing the screw rod 7 from loosening after long-term use.

[0024] The specific implementation process of the present utility model is as follows: When in use, pull the handle 912 in the direction of the elastic sponge 97. The movement of the handle 912 drives the movement of the connecting block 911. The movement of the connecting block 911 drives the movement of the pulling block 910. The movement of the pulling block 910 drives the movement of the slider 92. The movement of the slider 92 drives the movement of the groove 95. The movement of the groove 95 drives the movement of the ball 96. The movement of the slider 92 compresses the elastic sponge 97. After the slider 92 moves to the specified position, move the sealing ring 3, the connecting sleeve 4, and the fixed sleeve 5 to the specified positions inside the booster fan body 1. Then move the rotating block 8. The movement of the rotating block 8 drives the annular groove 91 and the screw rod 7 to move in the direction of the fixed sleeve 5. The screw rod 7 moves and inserts into the fixed sleeve 5 to contact the thread groove 6. Then rotate the rotating block 8. The rotation of the rotating block 8 drives the screw rod 7 to rotate. The rotation of the screw rod 7 and the thread groove 6 perform a threading movement, thereby causing the screw rod 7 to have a relative displacement. After the screw rod 7 rotates to the specified position, the components such as the sealing ring 3 are thus limited, and the device is thus sealed, making the device easy to use;

[0025] When the screw rod 7 needs to be limited, release the handle 912. The elastic force of the elastic sponge 97 acts to push the slider 92 to move. The movement of the slider 92 drives the movement of the groove 95 and the pulling block 910. The movement of the pulling block 910 drives the movement of the connecting block 911 and the handle 912. The movement of the groove 95 drives the movement of the ball 96. The slider 92 moves into the annular groove 91, thereby limiting the screw rod 7 and preventing the screw rod 7 from loosening after long-term use.

[0026] This solution designs components such as the sealing ring 3, connecting sleeve 4, fixing sleeve 5, thread groove 6, screw rod 7, and rotating block 8. The sealing ring 3, connecting sleeve 4, and fixing sleeve 5 are moved to the designated positions inside the booster fan body 1, and then components such as the screw rod 7 are installed at the designated positions on the device, thereby limiting the components such as the sealing ring 3, and further sealing the device, making the device easy to use. By designing components such as the annular groove 91, slider 92, chute 93, guide rod 94, groove 95, and ball 96, by pulling the slider 92 to the designated position, then installing components such as the screw rod 7 and rotating block 8 at the designated positions, and then moving the slider 92 into the annular groove 91, the screw rod 7 is limited, preventing the screw rod 7 from loosening after long-term use.
