[0021] It should be emphasized that in this application, the valve body 1, the sealing groove 2, and the sealing gasket 3 are the prior art disclosed in the publication (announcement) number: CN220566665U.

[0022] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, a detailed description will be given below with reference to the accompanying drawings and specific embodiments.

[0023] As attached Figure 1 To the attached Figure 4 As shown, an embodiment of the present invention provides an exhaust valve with an adjustable connection angle, comprising a valve body 1 , a connecting assembly 6 , a limiting assembly 7 and a connecting disk 4 .

[0024] The valve body 1 is provided with a connecting assembly 6, which includes a driving groove 601, a gear 602, a rotating rod 603, a threaded rod 604, an internal threaded ring 605 and a limiting hole 606. A driving groove 601 is provided at one end of the outer wall of the valve body 1, and the top and bottom of the driving groove 601 are rotatably connected to the rotating rod 603. A gear 602 is fixedly sleeved on the rotating rod 603. One end of the rotating rod 603 passes through the valve body 1 and is fixedly connected to the threaded rod 604. An internal threaded ring 605 is also rotatably connected in the driving groove 601, and the internal threaded ring 605 is meshed with the two gears 602. A number of limiting holes 606 are provided on the edge of the internal threaded ring 605. A connecting disk 4 is provided on one side of the valve body 1, and a number of adjusting holes 5 are provided on the edge of the connecting disk 4. The threaded rod 604 is threadedly connected to the adjacent adjusting holes 5.

[0025] It should be noted that: when the connecting plate 4 needs to be installed, first adjust the connecting plate 4 to a suitable connection angle, then connect the adjustment hole 5 to the threaded rod 604, and then rotate the internal threaded ring 605 to drive the gear 602 to rotate, the gear 602 drives the rotating rod 603 to rotate, and the rotating rod 603 drives the threaded rod 604 to rotate, and gradually completes the fixed installation of the connecting plate 4.

[0026] The valve body 1 is provided with a connecting assembly 6, which includes a driving groove 601, a gear 602, a rotating rod 603, a threaded rod 604, an internal threaded ring 605 and a limiting hole 606. A driving groove 601 is provided at one end of the outer wall of the valve body 1. The top and bottom of the driving groove 601 are rotatably connected to the rotating rod 603. A gear 602 is fixedly sleeved on the rotating rod 603. One end of the rotating rod 603 passes through the valve body 1 and is fixedly connected to the threaded rod 604. An internal threaded ring 605 is also rotatably connected in the driving groove 601. The internal threaded ring 605 is meshed with the two gears 602, and a plurality of limiting holes 606 are provided on the edge of the internal threaded ring 605.

[0027] It should be noted that: by pulling the pull head 705, the limiting rod 702 is driven to move, and the limiting rod 702 drives the limiting plate 703 to move. While the limiting plate 703 compresses the spring 704 with the help of the fixing plate 701, the limiting rod 702 slides out of the limiting hole 606, completing the release of the limit of the internal threaded ring 605.

[0028] It needs to be further explained that: when the internal thread ring 605 needs to be limited, first align the limiting hole 606 and the limiting rod 702, then loosen the pull head 705, the spring 704 pushes the limiting plate 703 and drives the limiting rod 702 to be inserted into the interior of the limiting hole 606, thereby fixing the position of the internal thread ring 605, preventing loosening, and improving the connection stability of the device.

[0029] The end of the limiting rod 702 inserted into the limiting hole 606 is arc-shaped, which facilitates the limiting rod 702 to be smoothly inserted into the limiting hole 606.

[0030] The outer surface of the limiting rod 702 is smooth, so that the limiting rod 702 can slide smoothly in the fixing plate 701.

[0031] The side of the slider 705 is provided with anti-slip grooves to increase friction and facilitate pulling the slider 705.

[0032] A sealing groove 2 is provided at one end of the valve body 1, and a sealing gasket 3 is provided inside the sealing groove 2. The sealing gasket 3 is in contact with the connecting disk 4. The sealing gasket 3 is made of rubber. Through the setting of the sealing groove 2 and the sealing gasket 3, the sealing operation between the valve body 1 and the connecting disk 4 is achieved.

[0033] The working process of this utility model is as follows:

[0034] First, rotate the connecting plate 4 according to the required connection angle, rotate the connecting plate 4 to the appropriate angle, and connect the adjustment hole 5 to the threaded rod 604;

[0035] Next, the pull head 705 is pulled to drive the limiting rod 702 to slide out of the limiting hole 606, thereby releasing the limiting of the internal thread ring 605;

[0036] Then, the internal thread ring 605 is rotated to drive the gear 602, the rotating rod 603, and the threaded rod 604 to rotate, thereby gradually completing the fixed installation of the connecting plate 4;

[0037] Finally, the pull head 705 is released, and the spring 704 pushes the limiting plate 703 and drives the limiting rod 702 to be inserted into the limiting hole 606, thereby fixing the position of the internal thread ring 605.

[0038] Finally, a few points should be explained: First, in the description of this application, it should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense, and may refer to mechanical or electrical connections, internal communication between two components, or direct connection.
