Fixing blocks are fixedly installed on both sides inside the cut-off cylinder. Return springs are fixedly installed on both the front and rear sides of the fixing blocks. Cylindrical sections are fixedly installed on both the front and rear sides of the top of the fixing blocks. A rotating lug 1 and a rotating lug 2 are provided between the cylindrical sections.

Connecting lug 2 is fixedly installed on both sides of the rear end of the semi-circular baffle 2, and a semi-circular baffle 1 is fixedly installed at the rear end of connecting lug 1.

[0004] However, the current septic tank flange connection mechanism has the following problems: it cannot allow the action block to be locked inside the semi-circular groove, it cannot further fix the pin structure, it cannot make the pipe connection more secure, and it cannot achieve the effect of easy installation. Therefore, we propose a modular flange connection mechanism for quick disassembly and assembly. Utility Model Content

[0005] The purpose of this invention is to provide a modular flange connection mechanism that allows for quick assembly and disassembly. This mechanism solves the problems in related technologies where the action block cannot be locked inside the semi-circular groove, the pin structure cannot be further fixed, the pipe connection cannot be made more secure, and the installation cannot be facilitated.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] A modular flange connection mechanism for quick assembly and disassembly includes a pipe body and a connecting block. The connecting block is disposed on the circumferential surface of the pipe body, and a fixing plate is disposed on the outer surface of the connecting block. The fixing plate is disposed on the outer surface of the fixing plate. The disassembly and assembly mechanism includes a pin structure disposed on the side of the fixing plate. A through groove is formed on the side of the fixing plate. One end of a spring is fixedly connected to the side of the fixing plate. An actuating block is fixedly connected to the end of the spring away from the side of the fixing plate. A semi-circular groove is formed on the circumferential surface of the pin structure.

[0008] Preferably, a telescopic rod is fixedly connected to the side of the fixed plate, an action plate is fixedly connected to the outer surface of the telescopic rod, a slot is formed on the inner wall of the action plate, a force spring is fixedly connected to the inner wall of the slot, and a clamping block is fixedly connected to the end of the force spring away from the slot. This design allows the telescopic rod to adjust the position of the action plate, making the force on the circumferential surface of the pin structure more uniform.

[0009] Preferably, the action plate is hollow, the slot is located on the movement trajectory of the clamping block, the clamping block is T-shaped, and there are four clamping blocks arranged in a circumferential array on the circumferential surface of the action plate. This design is beneficial for the clamping blocks to clamp the circumferential surface of the pin structure.

[0010] Preferably, the pipe body is provided with a sealing device inside, the sealing device including a sealing gasket, the sealing gasket is disposed at the connection of the two pipe bodies, and the inner surface of the sealing gasket is provided with an auxiliary plate. This design is beneficial to the sealing gasket being able to seal the two connected pipes to prevent leakage.

[0011] Preferably, a receiving plate is fixedly connected to the inner surface of the auxiliary plate, a rotating shaft is fixedly connected to the side of the receiving plate, a force-bearing rod is hinged to the circumferential surface of the rotating shaft, a sleeve is hinged to the outer surface of the force-bearing rod, a rotating rod passes through the circumferential surface of the sleeve, a torsion spring is fixedly connected to the circumferential surface of the sleeve, and a baffle assembly is fixedly connected to the circumferential surface of the rotating rod. This design is beneficial because when the baffle assembly is impacted by water flow, it will force the force-bearing rod to make an arc-shaped movement.

[0012] Preferably, the angle between the force-bearing rod and the baffle assembly is less than 90 degrees, and the number of the receiving plates is four, arranged in pairs and symmetrical to each other along the vertical central axis of the tube. This design helps the receiving plates to support the rotating shaft and the force-bearing rod.

[0013] Preferably, the action block is slidably connected to the inner wall of the through groove, the action block is C-shaped, and one end of the action block is an arc surface. This design is beneficial for the action block to slide on the inner wall of the through groove under force.

[0014] The technical effects achieved by this utility model are as follows:

[0015] 1. This utility model, through the setting of the disassembly and assembly mechanism, allows the circumferential surface of the pin structure to rub against the arc surface of the actuating block when the actuating block moves to its maximum extent on the inner wall of the through groove, until the actuating block comes into contact with the semi-circular groove, so that the actuating block is stuck inside the semi-circular groove, further fixing the pin structure. Moreover, the operator can adjust the position of the actuating plate by adjusting the length of the pin structure, so that the clamping force of the clamping block on the pin structure is in the center position, which is convenient for installation and can also achieve the function of fixed connection.

[0016] 2. By setting up a sealing device, the force-bearing rod applies force to the auxiliary plate through the rotating shaft and the receiving plate, making the sealing gasket more tightly connected to the inner wall of the pipe. This ensures that the sealing gasket is more tightly connected to the inside of the pipe when impacted by water flow, and will not fall off due to strong impact. Attached Figure Description

[0024] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0025] like Figure 1-5As shown, the modular flange connection mechanism for quick assembly and disassembly includes a pipe body 1 and a connecting block 2. The connecting block 2 is disposed on the circumferential surface of the pipe body 1. A fixing plate 3 is disposed on the outer surface of the connecting block 2. A disassembly and assembly mechanism 4 is disposed on the outer surface of the fixing plate 3. The disassembly and assembly mechanism 4 includes a pin structure 41, which is disposed on the side of the fixing plate 3. A through groove 42 is provided on the side of the fixing plate 3. One end of a spring 43 is fixedly connected to the side of the fixing plate 3. An actuating block 44 is fixedly connected to the end of the spring 43 away from the side of the fixing plate 3. A semi-circular groove 45 is provided on the circumferential surface of the pin structure 41.

[0026] A telescopic rod 46 is fixedly connected to the side of the fixed plate 3. An action plate 47 is fixedly connected to the outer surface of the telescopic rod 46. A slot 48 is provided on the inner wall of the action plate 47. A force spring 49 is fixedly connected to the inner wall of the slot 48. A clamping block 410 is fixedly connected to the end of the force spring 49 away from the slot 48. This design is beneficial for the telescopic rod 46 to adjust the position of the action plate 47, so that the force on the circumferential surface of the pin structure 41 is more uniform.

[0027] The action plate 47 is hollow in shape, the slot 48 is located on the movement trajectory of the clamping block 410, the clamping block 410 is T-shaped, and there are four clamping blocks 410 arranged in a circumferential array on the circumferential surface of the action plate 47. This design is beneficial for the clamping block 410 to clamp the circumferential surface of the pin structure 41.

[0028] Based on the above structure, firstly, to facilitate the assembly and disassembly of the flange connector, when the operator needs to connect the two pipe bodies 1 using the flange connector, the operator only needs to fix the pin structure 41 to the side of the fixing plate 3. When the pin structure 41 is placed on the side of the fixing plate 3, the clamping block 410 first contacts the circumferential surface of the pin structure 41, forcing the clamping block 410 to clamp the circumferential surface of the pin structure 41 through the force spring 49. Furthermore, when the pin structure 41 penetrates to the side of the fixing plate 3, the actuating block 44 can engage with the pin. The circumferential surfaces of the structure 41 contact each other, so that when the action block 44 moves to its maximum extent on the inner wall of the through groove 42, the circumferential surface of the pin structure 41 rubs against the arc surface of the action block 44 until the action block 44 contacts the semi-circular groove 45, so that the action block 44 is stuck inside the semi-circular groove 45, further fixing the pin structure 41. The operator can adjust the position of the action plate 47 by adjusting the length of the pin structure 41, so that the clamping force of the clamping block 410 on the pin structure 41 is in the center position, which is convenient for installation and can also achieve the function of fixed connection.

[0029] like Figure 1-5As shown, a sealing device 5 is provided inside the pipe body 1. The sealing device 5 includes a sealing gasket 51. The sealing gasket 51 is provided at the connection of the two pipe bodies 1. An auxiliary plate 52 is provided on the inner surface of the sealing gasket 51. This design is beneficial for the sealing gasket 51 to seal the two connected pipes to prevent leakage.

[0030] A receiving plate 53 is fixedly connected to the inner surface of the auxiliary plate 52. A rotating shaft 54 ​​is fixedly connected to the side of the receiving plate 53. A force-bearing rod 55 is hinged to the circumferential surface of the rotating shaft 54. A sleeve 56 is hinged to the outer surface of the force-bearing rod 55. A rotating rod 57 passes through the circumferential surface of the sleeve 56. A torsion spring 58 is fixedly connected to the circumferential surface of the sleeve 56. A baffle assembly 59 is fixedly connected to the circumferential surface of the rotating rod 57. This design is beneficial because when the baffle assembly 59 is impacted by water flow, it will force the force-bearing rod 55 to make an arc-shaped movement.

[0031] The angle between the force-bearing rod 55 and the baffle assembly 59 is less than 90 degrees. There are four support plates 53, arranged in pairs, and they are symmetrical about each other along the vertical central axis of the tube body 1. This design is beneficial for the support plates 53 to support the rotating shaft 54 ​​and the force-bearing rod 55.

[0032] The action block 44 is slidably connected to the inner wall of the through groove 42. The shape of the action block 44 is C-shaped, and one end of the action block 44 is arc-shaped. This design is conducive to the action block 44 being able to slide on the inner wall of the through groove 42 under force.

[0033] According to the above structure, after the pipe body 1 is connected, in order to prevent the internal liquid of the pipe body 1 from leaking, a sealing gasket 51 is needed to seal the two pipe bodies 1. However, in order to prevent the sealing gasket 51 from falling off or not making good contact with the pipe body 1, when the water flows through the pipe body 1, the impact force of the water flow forces the baffle assembly 59 to be displaced in the direction of the water flow, which forces the rotating rod 57 to move, so that the force rod 55 makes an arc-shaped movement through the sleeve 56, so that the included angle between the two force rods 55 gradually approaches 180 degrees, so that the force rod 55 applies force to the auxiliary plate 52 through the rotating shaft 54 ​​and the receiving plate 53, making the sealing gasket 51 more tightly contacted with the inner wall of the pipe body 1, so that the sealing gasket 51 is more tightly connected to the inside of the pipe body 1 when the water flow impacts, and will not fall off due to the impact. However, when connecting the two pipe bodies 1, one end of the baffle assembly 59 needs to be placed in the opposite direction of the water flow to ensure that the baffle assembly 59 is subjected to the impact force.

[0034] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
