[0059] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0060] Example:

[0061] like Figure 1 and Figure 2 As shown, an embodiment of the present application discloses a quick door opening mechanism for quickly opening and closing a tank cover, and its specific structure includes: a head 1, a cylinder 2, a tank cover flange 3, a tank body flange 4, a clamp 5 and a rotation drive assembly 6.

[0062] like Figure 5 As shown, the tank cover flange 3 includes: a first circular tube section 31 and a first retaining ring portion 32 .

[0063] Specifically, the first circular tube segment 31 is sleeved on the end of the head 1, preferably fixed by welding; the first retaining ring portion 32 is composed of a plurality of first protruding teeth 321, which are evenly arranged on the outer circumferential surface of the first circular tube segment 31, and the number is preferably sixteen, but it can also be other numbers, without specific limitation.

[0064] like Figure 6 As shown, the tank flange 4 includes: a second circular tube section 41 , a second retaining ring portion 42 and a limiting circular ring portion 43 .

[0065] Specifically, the second circular tube segment 41 is sleeved on the end of the cylinder 2, preferably fixed by welding; the second retaining ring portion 42 is composed of a plurality of second protruding teeth 421, which are evenly arranged on the outer circumferential surface of the second circular tube segment 41 and are staggered with the first protruding teeth 321. The number is also preferably sixteen, but can also be other numbers, without specific limitation; the limiting circular ring portion 43 is sleeved on the outer circumferential surface of the second circular tube segment 41, and is located on the side of the second retaining ring portion 42 away from the tank cover flange 3.

[0066] like Figure 7 As shown, the clamp 5 includes: a third circular tube segment 51 , a first circular ring portion 52 and a second circular ring portion 53 .

[0067] Specifically, the third circular tube segment 51 is movably sleeved on the outer circumference of the first retaining ring portion 32 and the second retaining ring portion 42; the first circular ring portion 52 is arranged in the third circular tube segment 51, and a plurality of first clamping grooves 521 are opened on the inner circumference, and the first clamping grooves 521 correspond to the first protruding teeth 321 one by one and are adapted to each other; the second circular ring portion 53 is arranged in the third circular tube segment 51, and a plurality of second clamping grooves 531 are opened on the inner circumference, and the second clamping grooves 531 correspond to the second protruding teeth 421 one by one and are adapted to each other.

[0068] Among them, Figure 1 As shown, a first annular groove 5A is formed between the first annular portion 52 and the second annular portion 53 for accommodating the first retaining ring portion 32 and the second retaining ring portion 42 and keeping the two aligned and in close contact.

[0069] like Figure 3 and Figure 4 As shown, the rotation drive assembly 6 is disposed between the cylinder 2 and the clamp 5, and is used to drive the clamp 5 to rotate circumferentially.

[0070] When installing the clamp 5, the second groove 531 on the second annular portion 53 is kept in one-to-one correspondence with the second convex tooth 421, so that the second annular portion 53 can axially pass through the second retaining ring portion 42 until it is blocked by the limiting annular portion 43. At this time, the second retaining ring portion 42 will be placed in the first annular groove 5A, and then the clamp 5 is rotated circumferentially to keep the second groove 531 and the second convex tooth 421 misaligned, so that the clamp 5 can be axially limited.

[0071] When closing the tank cover, the clamp 5 is driven to rotate circumferentially by the rotary drive assembly 6, so that the first clamping groove 521 on the first annular portion 52 maintains a one-to-one correspondence with the first convex tooth 321, and then the tank cover is moved axially, so that the first retaining ring portion 32 passes through the first annular portion 52 and enters the first annular groove 5A until the first circular tube segment 31 and the second circular tube segment 41 are aligned and fit, and then the clamp 5 is driven to rotate circumferentially by the rotary drive assembly 6 again, so that the first clamping groove 521 and the first convex tooth 321 remain misaligned, so that the tank cover flange 3 and the tank body flange 4 are locked and fixed by the clamp 5, thereby completing the docking, so that the tank cover closes the access port at the end of the tank body.

[0072] The utility model can complete the locking of the tank cover flange 3 and the tank body flange 4 by rotating the clamp 5 circumferentially through the rotating drive component 6. It has a simple structure, reduces the manufacturing cost, has a high compact structure, reduces the overall volume, is easy to install and arrange, is simple to operate, is easy to use, and improves the switching efficiency.

[0073] In some embodiments, Figure 5 and Figure 6 As shown, in order to improve the structural strength, the first protruding tooth 321 and the second protruding tooth 421 are both fan-shaped structures, which have the advantages of compact structure and stable connection, thereby shortening the diameter of the mechanism, enhancing the load-bearing capacity, and significantly improving the locking effect.

[0074] like Figure 5 As shown, an inclined surface 321 a is formed on one side of the non-matching end surface of the first protruding tooth 321 .

[0075] When the tank cover is closed, the clamp 5 can axially press the first protruding tooth 321 through the inclined surface 321a during the circumferential rotation, so that the first circular tube segment 31 and the second circular tube segment 41 gradually fit tightly.

[0076] The above structural design significantly improves the sealing effect, and the structure is simple, easy to manufacture, and does not add any extra operating steps, thus ensuring the switching efficiency.

[0077] In some embodiments, Figure 2 , Figure 5 and Figure 6As shown, in order to improve the sealing effect, the opposing end surfaces of the first circular tube section 31 and the first retaining ring portion 32 are flush with each other, and the opposing end surfaces of the second circular tube section 41 and the second retaining ring portion 42 are flush with each other.

[0078] Through the above structural design, the first retaining ring portion 32 and the second retaining ring portion 42 can also maintain a close fit, thereby increasing the overall contact area and enhancing the sealing effect.

[0079] In some embodiments, Figure 2 and Figure 8 As shown, an accommodating annular groove 311 is provided on the end surface of the first circular tube section 31 , and a sealing ring 7 is installed in the accommodating annular groove 311 .

[0080] The provision of the accommodating annular groove 311 facilitates the installation of the sealing ring 7 , thereby improving the installation stability and the compactness of the structure. The provision of the sealing ring 7 enhances the air tightness.

[0081] Based on the above embodiments, Figure 8 As shown, the bottom surface of the accommodating annular groove 311 is provided with an annular groove 311a, and one end of the sealing ring 7 has an annular protrusion 71, the cross section of the annular protrusion 71 is trapezoidal and matched with the annular groove 311a.

[0082] Exemplarily, the cross-section of the annular protrusion 71 is a right-angled trapezoid for easy installation, but is not limited thereto and may also be an isosceles trapezoid or other shapes without specific limitation.

[0083] The engagement between the annular groove 311 a and the annular protrusion 71 can limit the sealing ring 7 from being separated from the accommodating annular groove 311 , thereby improving the installation stability and ensuring the use effect.

[0084] In some embodiments, Figure 2 As shown, a second annular groove 4A is formed between the second retaining ring portion 42 and the limiting annular portion 43 , and the second annular groove 4A matches the second annular portion 53 .

[0085] By limiting the width of the second annular groove 4A as mentioned above, the clamp 5 is axially limited, thereby preventing the clamp 5 from axially shaking after installation, thereby improving stability.

[0086] In some embodiments, Figure 3 and Figure 4 As shown, the rotation driving assembly 6 includes: a rack 61 , a gear 62 , a rotation shaft 63 and a driving rod 64 .

[0087] Specifically, the rack 61 is fan-shaped and is disposed on the outer circumferential surface of the cylinder 2; the gear 62 is meshed with the rack 61; one end of the rotating shaft 63 is coaxially connected to the gear 62, which is preferably a fixed sleeve, and the other end is rotatably connected to the outer circumferential surface of the third circular tube segment 51; the driving rod 64 is disposed on the outer circumferential surface of the gear 62 and is located on the side away from the cylinder 2.

[0088] Exemplarily, a circular tube is welded on the outer circumference of the third circular tube segment 51, one end of the rotating shaft 63 is rotatably sleeved with the circular tube, and limiting rings are fixedly sleeved on both sides of the circular tube for axial limiting, thereby completing the rotational connection.

[0089] During driving, the operator moves the driving rod 64 , and the driving rod 64 drives the gear 62 to move, and the gear 62 rolls along the rack 61 . At the same time, the gear 62 drives the third circular tube segment 51 to rotate circumferentially through the rotating shaft 63 .

[0090] The above design can facilitate the operator to drive the clamp 5 to rotate circumferentially more conveniently, and the structure is simple and easy to operate. Through the lever principle, the effect of saving time and effort is achieved, and the actual application effect is good.

[0091] In some embodiments, Figure 2 As shown, it also includes a plurality of rolling support assemblies 8, which are arranged on one side of the third circular tube segment 51 and are arranged around the limiting circular ring portion 43; preferably, they are arranged at even intervals to avoid stress concentration and improve the support effect.

[0092] Specifically, each rolling support assembly 8 includes a support shaft 81 and a roller 82 .

[0093] The support shaft 81 is axially mounted on the side of the third circular tube segment 51; the support shaft 81 is preferably a bolt, which is threadedly connected to the side of the third circular tube segment 51, which can axially limit the roller 82 and improve the efficiency of disassembly and assembly. The roller 82 is sleeved on the support shaft 81 and fits the outer circumferential surface of the limiting annular portion 43.

[0094] By providing the rolling support assembly 8, the clamp 5 is rollingly supported on the limiting annular portion 43, thereby greatly reducing the resistance encountered during circumferential rotation, avoiding jamming, improving the smoothness of movement, and ensuring smooth opening and closing of the door.
