Description

Technical Field

[0001] This utility model belongs to the field of mining ventilation duct technology, and in particular relates to a sealing connection structure for mining ventilation ducts. Background Technology

[0002] Ventilation management is a crucial component of safe production in mines. Mine ventilation ensures sufficient fresh air underground, enabling miners to work safely without experiencing discomfort due to oxygen deficiency, thereby improving their working environment and guaranteeing their safety.

[0003] When using mine ventilation ducts, it is often necessary to connect multiple sets of pipes. However, some pipes are designed as a single piece, and the connection method is mostly to connect them with multiple sets of bolts. Although they can be connected, it is difficult to quickly disassemble and repair the pipes, which reduces the efficiency of pipe disassembly and repair and delays the progress of normal processing. Summary of the Invention

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a sealing connection structure for a mine ventilation duct, which can effectively solve the problems of the existing technology.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a sealing connection structure for a mine ventilation duct, comprising a main connecting pipe and a connecting auxiliary pipe disposed on one side of the main connecting pipe, and further comprising:

[0007] An extended sealing mechanism is located inside the main connecting pipe and connected to the auxiliary connecting pipe;

[0008] A connecting ring is fixed to the upper end face of the main connecting pipe, and an extension ring is fixed to the side of the auxiliary connecting pipe near the main connecting pipe.

[0009] A locking mechanism, located on the outer surface of the connecting ring, is used to connect the main connecting pipe to the auxiliary connecting pipe;

[0010] The positioning mechanism is located inside the extension ring.

[0011] Furthermore, the extended sealing mechanism includes an extension tube and a limiting groove. The extension tube is fixed at the center of one side of the connecting main tube and is arranged in a stepped shape. The limiting groove is opened on the inner side of the connecting auxiliary tube, and the extension tube is slidably embedded inside the limiting groove.

[0012] Furthermore, the locking mechanism includes a connecting thread and a connecting sleeve. The connecting thread is disposed on the outer surfaces of the connecting ring and the extension ring, and the connecting sleeve is fitted onto the outer surface of the connecting main tube and connected to the connecting thread on the outer surface of the extension ring.

[0013] Furthermore, a locking plate is rotatably connected to one side of the connecting sleeve, and a locking slide rod is evenly fixed to one side of the locking plate. An extension slide groove is provided inside the connecting ring, and a locking slide groove is provided inside the extension ring, with the extension slide groove corresponding to the locking slide groove.

[0014] Furthermore, a locking clip is fixed to one end of the locking plate, and the cross-section of the locking clip is a "T" shaped structure and is rotatably connected along one end of the connecting sleeve.

[0015] Furthermore, the positioning mechanism includes a positioning rod, a return spring, and a positioning groove. The positioning rod is slidably engaged inside the extension ring, the return spring is sleeved on the outer surface of the positioning rod, the positioning groove is evenly distributed on the upper end face of the extension tube, and the upper end of the positioning rod is in contact with the inner wall of the connecting sleeve.

[0016] This utility model has the following beneficial effects:

[0017] This invention enables the connection of the main connecting pipe and the auxiliary connecting pipe by setting an extension tube and a limiting groove. Then, the setting of the connecting sleeve can be sleeved on the outer surface of the main connecting pipe and connected to the connecting thread on the outer surface of the connecting ring and the extension ring, thereby connecting and limiting the main connecting pipe and the auxiliary connecting pipe. Furthermore, when the setting of the connecting sleeve is adjusted, the position of the locking plate can be adjusted, so that the locking slide rod can pass through the extension slide groove and the locking slide groove, which can strengthen the connection between the main connecting pipe and the auxiliary connecting pipe and prevent the connection from breaking and affecting subsequent processing. Moreover, when the connecting sleeve contacts the top of the positioning rod, the setting of the positioning mechanism can lock the extension tube, which can prevent the extension tube from shaking and affecting subsequent processing.

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0027] Please see Figure 1-5 As shown, this utility model is a sealing connection structure for a mine ventilation duct, including a main connecting pipe 1 and a connecting auxiliary pipe 2 disposed on one side of the main connecting pipe 1, and further including:

[0028] An extension sealing mechanism is installed inside the main connecting pipe 1 and connected to the auxiliary connecting pipe 2. The extension sealing mechanism includes an extension pipe 3 and a limiting groove 4. The extension pipe 3 is fixed at the center of one side of the main connecting pipe 1 and is stepped. The limiting groove 4 is opened inside the auxiliary connecting pipe 2, and the extension pipe 3 is slidably embedded inside the limiting groove 4. By fixing the extension pipe 3 to one side of the main connecting pipe 1 and slidingly engaging it inside the limiting groove 4, the main connecting pipe 1 and the auxiliary connecting pipe 2 can be connected, thereby reinforcing the connection between the two.

[0029] A connecting ring 5 is fixed to the upper end face of the main connecting pipe 1, and an extension ring 6 is fixed to the side of the auxiliary connecting pipe 2 near the main connecting pipe 1. A locking mechanism is provided on the outer surface of the connecting ring 5 to connect the main connecting pipe 1 and the auxiliary connecting pipe 2. The locking mechanism includes a connecting thread 7 and a connecting sleeve 8. The connecting thread 7 is provided on the outer surfaces of the connecting ring 5 and the extension ring 6. The connecting sleeve 8 is fitted onto the outer surface of the main connecting pipe 1 and connected to the connecting thread 7 on the outer surface of the extension ring 6. The connecting sleeve 8 can be fitted onto the outer surface of the main connecting pipe 1 and connected to the connecting thread 7 on the outer surfaces of the connecting ring 5 and the extension ring 6, thereby connecting and limiting the main connecting pipe 1 and the auxiliary connecting pipe 2. Since the connecting sleeve 8 can quickly reinforce the connection between the main connecting pipe 1 and the auxiliary connecting pipe 2, it can avoid multiple sets of bolt connections, which would affect the disassembly and maintenance of the main connecting pipe 1 and the auxiliary connecting pipe 2, thus affecting their subsequent processing. A locking plate 9 is rotatably connected to one side of the connecting sleeve 8, and a locking plate 9 is uniformly fixed on one side of the locking plate 9. The locking slide rod 11 has an extension slide groove 12 inside the connecting ring 5 and a locking slide groove 13 inside the extension ring 6. The extension slide groove 12 and the locking slide groove 13 correspond to each other. When the connecting sleeve 8 can rotate, the locking plate 9 can be adjusted accordingly. Then, the locking slide rod 11 slides and engages with the extension slide groove 12 inside the connecting ring 5 and extends into the locking slide groove 13 inside the extension ring 6. This can strengthen the connection between the main connecting pipe 1 and the auxiliary connecting pipe 2, preventing the connection from breaking and affecting subsequent processing, thus increasing the service life of the main connecting pipe 1 and the auxiliary connecting pipe 2. One end of the locking plate 9 is fixed with a locking clip 10. The locking clip 10 has a "T" shaped cross-section and rotates along one end of the connecting sleeve 8. The locking clip 10 can limit the locking plate 9, allowing the locking plate 9 to slide laterally when the connecting sleeve 8 is rotated and adjusted, thus ensuring the clamping effect of the locking slide rod 11.

[0030] A positioning mechanism is located inside the extension ring 6. The positioning mechanism includes a positioning rod 14, a return spring 15, and a positioning groove 16. The positioning rod 14 is slidably engaged inside the extension ring 6, and the return spring 15 is sleeved on the outer surface of the positioning rod 14. The positioning groove 16 is evenly distributed on the upper end face of the extension tube 3, and the upper end of the positioning rod 14 contacts the inner wall of the connecting sleeve 8. When the connecting sleeve 8 contacts the top of the positioning rod 14, the positioning rod 14 can be pushed downward, thereby allowing the lower end of the positioning rod 14 to be slidably engaged in the positioning groove 16 on the outer side of the extension tube 3, thus locking the extension tube 3 and preventing the extension tube 3 from shaking, which would affect subsequent processing. If the connecting sleeve 8 rotates, the return spring 15 can reset the positioning rod 14, thus facilitating subsequent processing.

[0031] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
