A sealing ring b is provided on the inner side of the fixing base a, and a sealing ring a is provided on the inner side of the fixing base b. The sealing ring a and the sealing ring b are in contact.

[0012] As a further description of the above technical solution:

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] Reference Figures 1-3 This utility model provides an embodiment of a modular ventilation duct connector for mining engineering, including a duct 1. A fixing seat b3 is fixedly connected to the outer wall of the duct 1. A fixing seat a2 is in contact with the surface of the fixing seat b3. The fixing seat a2 serves to connect and fix a quick-release mechanism, making the whole more modular. A sealing ring b14 is provided on the inner side of the fixing seat a2, and a sealing ring a13 is provided on the inner side of the fixing seat b3. The sealing ring a13 is in contact with the sealing ring b14. By making the sealing ring b14 and the sealing ring a13 replaceable, the sealing ring a13 and the sealing ring b14 are installed in an interlocking manner, which improves the sealing effect and avoids gas leakage caused by the complex environment of the mining site. The outer wall of the fixing seat a2 is provided with a quick-release mechanism.

[0038] Reference Figure 2 and Figure 5 and Figure 7The quick-release mechanism includes a fixing block 4. A mounting rod 11 is fixedly connected to the center of the outer wall of the fixing block 4. The outer wall of the mounting rod 11 contacts a connecting box 5. The outer wall of the connecting box 5 has a slot. When connection is required, the end of the mounting rod 11 away from the fixing block 4 will engage with the connecting block 17 through the slot. The connecting box 5 serves to fix and protect the telescopic rod 16, the connecting block 17, and the spring 15 on the inner wall. The end of the mounting rod 11 away from the fixing block 4 has a slot. The mounting rod 11 engages with the outer wall of the connecting block 17 through the slot. The slot of the mounting rod 11 compresses the outer wall of the connecting block 17, thus engaging the outer wall of the connecting block 17. Box 5 is fixedly connected to both sides of the outer wall of the fixed base b3. A connecting block 17 is elastically connected to the inner side wall of box 5 via spring 15. The connecting block 17 serves to connect the mounting rod 11, thereby controlling the installation of the overall quick-release mechanism. One end of spring 15 is fixedly connected to the inner side wall of box 5, and the other end is fixedly connected to the outer wall of connecting block 17. The function of spring 15 is to allow the mounting rod 11, which has a slot, to engage with the outer wall of connecting block 17 and then return to its original position. When the quick-release mechanism needs to be released, connecting block 17 will press against spring 15, and after pressing, it will return to its original position. A telescopic rod 16 is fixedly connected to one side of the connecting block 17. The end of the telescopic rod 16 away from the connecting block 17 is fixedly connected to the inner side wall of the connecting box 5. The telescopic rod 16 is located inside the spring 15, serving to connect the connecting block 17 and the connecting box 5, and also providing stability when the spring 15 extends or retracts. A connecting rod 6 is fixedly connected to the other side of the connecting block 17. The connecting rod 6 serves as a transmission mechanism. Moving the guide plate 19 downward will drive the connecting rod 6 to move closer to the pipe 1. A control box 7 is slidably connected to the outer wall of the bottom end of the connecting rod 6. The top of the control box 7 is fixedly connected to the bottom outer wall of the fixed seat b3. The inner wall of the control box 7 is slidably connected to... The guide plate 19 has two slots at both ends of its outer wall, allowing it to move up and down only within the inner wall of the control box 7. A guide block is provided on the inner side of the control box 7. A sliding block 18 is slidably connected to the inner wall of the guide plate 19. Two sets of inclined grooves are provided on the outer wall of the guide plate 19. The sliding block 18 slides upward through the inclined grooves of the guide plate 19, which controls the disassembly of the overall quick-release mechanism. The sliding block 18 is fixedly connected to the end of the connecting rod 6 away from the connecting block 17. A pull rod 12 is fixedly connected to the bottom end of the guide plate 19. The pull rod 12 is slidably connected to the bottom inner wall of the control box 7. The disassembly of the overall quick-release mechanism of the connector can be controlled by pulling the pull rod 12 downward.

[0039] Reference Figure 4 and Figure 5A guide rod 10 is fixedly connected to the outer side of the right-side fixing block 4. The middle end of the guide rod 10 is fixedly connected to the side wall of the fixing block 4 on the other side of the connector, so that the guide rod 10 does not move synchronously with the reinforcing block 8. The guide rod 10 plays a vertical guiding and limiting role for the reinforcing block 8, preventing the reinforcing block 8 from rotating synchronously with the bidirectional threaded rod 9. The outer arc surface of the guide rod 10 is slidably connected to the reinforcing block 8. There are two reinforcing blocks 8, one at the top and one at the bottom. The movable reinforcing blocks 8 provide reinforcement for the quick-release mechanism. The inner side wall of the reinforcing block 8 is in contact with the outer wall of the fixing block 4 and the connecting box 5. A bidirectional threaded rod 9 is rotatably connected to the outer side of the left-side fixing block 4. The middle section of the bidirectional threaded rod 9 is rotatably connected to the side wall of the fixing block 4, preventing the bidirectional threaded rod 9 from loosening and falling off during rotation. By setting the bidirectional threaded rod 9, the reinforcing blocks 8 can be controlled to move in opposite directions, thereby reinforcing the overall quick-release mechanism of the connector. For the reinforcement function, protrusions 20 are fixedly connected to the outer sidewalls of the fixing block 4 and the connecting box 5. Grooves are opened at both ends of the inner wall of the reinforcement block 8. The inner wall of the groove of the reinforcement block 8 contacts the outer wall of the protrusion 20. Two sets of protrusions 20 are provided on the outer side of the fixing block 4 and the connecting box 5. The appearance of the protrusions 20 is L-shaped. When the reinforcement block 8 reinforces the overall quick-release mechanism, the outer wall of the protrusion 20 contacts the inner wall of the reinforcement block 8 to lock the reinforcement block 8 and prevent loosening. The end of the reinforcement block 8 away from the guide rod 10 is provided with a threaded groove. The end of the reinforcement block 8 away from the guide rod 10 is threadedly connected to the outer wall of the bidirectional threaded rod 9. The reinforcement block 8 is threaded to the outer wall of the bidirectional threaded rod 9 through the threaded groove. The bidirectional threaded rod 9 can be used to control the up and down movement of the reinforcement block 8. The bidirectional threaded rod 9 has a self-locking effect, so that after the whole is pressed by the two sets of reinforcement blocks 8, the guide plate 19 is prevented from moving the connecting rod 6 due to gravity.

[0040] Working principle: When connecting two pipes 1, first place sealing rings a13 and b14 on the contact surface between the two connectors. By moving the two connectors towards each other, the mounting rod 11 of the left connector will pass through the slot opened in the connecting box 5 on the surface of the right connector and through the slot opened on the mounting rod 11. The slot is shaped with the right side being inclined and the left side being flat. The inclined surface of the slot of the mounting rod 11 will press against the outer wall of the connecting block 17, thereby causing the connecting block 17 to move backward and stretch the spring 15. The connecting block 17 will be fixed at the rear end of the inclined surface of the slot of the mounting rod 11. The spring 15 will cause the connecting block 17 to move backward and then reset, so that the mounting rod 11 can fully engage the connecting block 17, thereby enabling the two connecting pipes 1 to be installed quickly.

[0041] Conversely, when it is necessary to disassemble the two pipes 1, by pulling down the pull rod 12, the guide plate 19 moves downward. The sliding block 18, which is slidably connected in the inclined groove of the guide plate 19, will move upward, thereby controlling the connecting rod 6 to move towards the pipe 1. The connecting block 17 will be moved and squeeze the telescopic rod 16, so that the outer wall of the connecting block 17 will disengage from the inclined rear end of the slot of the mounting rod 11. The mounting rod 11 will release the engagement through the plane of the mounting rod 11. The spring 15 will reset after releasing the engagement of the connecting block 17. After the engagement is released, the mounting rod 11 will disengage from the inner wall of the hole of the connecting box 5, thereby completing the disassembly of the two connecting pipes 1.

[0042] After the installation of the connectors at both pipes 1 is completed, the bidirectional threaded rod 9 controls the bidirectional movement of the reinforcing block 8. The other end of the reinforcing block 8 is slidably connected to the outer wall of the guide rod 10, so that the reinforcing block 8 does not rotate synchronously with the bidirectional threaded rod 9. The inner wall of the reinforcing block 8 has a groove for inserting the protrusion 20 fixedly connected to the fixing block 4 and the connecting box 5. The reinforcing block 8 will reinforce the quick-release mechanism and perform secondary reinforcement. The reinforcing block 8 is set at the upper and lower positions of the connector. Due to the complex environment of the mining site, the reinforcing block 8 can also withstand a certain amount of external force, which will protect the sealing rings a13 and b14 in the middle of the connector and extend their service life.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
