Detailed Implementation

[0021] 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.

[0022] Please see Figure 1-5 This utility model provides a technical solution: a hole cover structure for a high temperature and high pressure dyeing machine, including a main cylinder 1 of the dyeing machine and a combination mechanism 2, wherein the combination mechanism 2 is provided on one side of the surface of the main cylinder 1 of the dyeing machine.

[0023] The combined mechanism 2 includes a manhole safety handle 201, a manhole base 202, a manhole cover 203, a manhole fastening hinge 204, a manhole seal 205, a fixing claw 206, a cover handle 207, a cover opening and closing trunnion 208, a movable fastening bolt 209, a hand-tightening nut 210, and a handle 211. A manhole safety handle 201 is installed on one side of the surface of the main cylinder 1 of the dyeing machine. A manhole base 202 is fixedly connected to the hole in the main cylinder 1 of the dyeing machine. A manhole cover 203 is attached to the surface of the manhole base 202, and a... The manhole fastening hinge 204 has a manhole seal 205 installed on one side of the manhole cover 203. A fixing claw 206 is welded to one side of the manhole cover 203. A cover handle 207 is fixedly connected to one side of the manhole cover 203. A cover opening / closing trunnion 208 is welded to the surface of the manhole cover 203. A movable fastening bolt 209 is fitted into one side of the manhole fastening hinge 204. A hand-tightening nut 210 is threaded onto the surface of the movable fastening bolt 209. A handle 211 is fixedly connected to one side of the hand-tightening nut 210. The manhole can be accessed via the manhole safety handle 201 and the manhole... The manhole base 202, manhole cover 203, manhole fastening hinge 204, manhole seal 205, fixing claw 206, manhole cover handle 207, manhole cover opening and closing trunnion 208, movable fastening bolt 209, hand-tightening nut 210, and handle 211 are configured to ensure that the manhole base 202 is fixedly connected to the main cylinder 1 of the dyeing machine, forming a fixed sealing base. The manhole seal 205 is located at the bottom of the manhole cover 203 and installed on the inner side of the manhole cover 203. It ensures airtightness and liquid tightness after fitting with the manhole base 202, preventing dyeing liquid leakage. When opening, operate handle 211 to loosen hand nut 210, causing movable fastening bolt 209 to disengage from fixed clamp 206. Then, use manhole cover handle 207 to pull manhole cover 203 and rotate it to the open position via manhole cover opening and closing trunnion 208. When closing, rotate manhole cover 203 to the aligned position to ensure that manhole seal 205 fits against manhole base 202. Then, tighten hand nut 210 to lock movable fastening bolt 209, completing the sealing operation. At the same time, manhole safety handle 201 is installed on the surface of the main cylinder 1 of the dyeing machine for convenient and quick inspection and operation.

[0024] Furthermore, the manhole base 202 and manhole cover 203 are positioned relatively straight, and the other side of the manhole seal 205 is fitted with the manhole base 202. Through the setting of the manhole seal 205, the manhole seal 205 fills the space between the manhole cover 203 and the manhole base 202, preventing outside air from entering the dyeing machine, ensuring the stability of the internal environment, preventing the dyeing liquid from being exposed to the air and affecting the process effect, preventing the dyeing liquid from leaking from the manhole interface, keeping the external environment of the dyeing machine clean, and preventing liquid loss. At the same time, when the dyeing machine is running, the manhole seal 205 forms a tight fit structure through compression deformation, which can effectively withstand the pressure inside the dyeing machine and avoid safety hazards caused by leakage under high pressure.

[0025] Furthermore, five sets of manhole fastening hinge seats 204 are provided, which are evenly distributed on the manhole base 202. Through the setting of the manhole fastening hinge seats 204, the manhole fastening hinge seats 204 are fixed on the manhole base 202, serving as the engagement fulcrum of the movable fastening bolt 209, providing a stable installation position, and ensuring that the fastening device does not shift or loosen during operation. At the same time, the manhole fastening hinge seats 204 and the movable fastening bolt 209 together form a hinge structure, allowing the movable fastening bolt 209 to rotate flexibly, making it convenient for users to operate the bolt when opening and closing the manhole cover 203, thus improving the convenience and efficiency of operation.

[0026] Furthermore, five sets of fixing claws 206 are provided, which are evenly distributed on the manhole cover 203. Through the setting of the fixing claws 206, the fixing claws 206 are welded to the outer surface of the manhole cover 203 and cooperate with the movable fastening bolt 209 to provide a firm clamping point for the fastening device, stably locking the manhole cover 203 onto the manhole base 202. At the same time, during the bolt tightening process, the fixing claws 206 evenly transmit the force applied by the movable fastening bolt 209 to the manhole cover 203, so that the manhole seal 205 fits tightly with the manhole base 202, ensuring the sealing effect.

[0027] Furthermore, the positions of the five sets of manhole fastening hinge seats 204 and the fixing claws 206 are aligned one by one. The manhole base 202 also has a cover opening and closing trunnion 208 on one side. By designing the position of the fixing claws 206 to correspond one-to-one with the manhole fastening hinge seats 204, it can ensure that the manhole cover 203 and the manhole base 202 are accurately aligned during installation, avoiding sealing failure or component damage due to misalignment. At the same time, the even distribution of multiple sets of manhole fastening hinge seats 204 and fixing claws 206 forms a multi-point clamping structure, effectively dispersing external forces and preventing the cover from deforming or loosening, thereby improving the stability and durability of the manhole assembly.

[0028] Furthermore, the movable fastening bolt 209 and the manhole fastening hinge seat 204 form a mutually rotating structure. One side of the surface of the movable fastening bolt 209 is fitted inside the fixed clamp 206. Through the setting of the movable fastening bolt 209, the movable fastening bolt 209 is fitted between the manhole fastening hinge seat 204 and the fixed clamp 206. Through the rotation of the hand-tightening nut 210, the manhole cover 203 is firmly fixed on the manhole base 202, ensuring that the manhole seal 205 is tightly fitted with the manhole base 202, achieving a reliable seal. The bolt is connected by threads, converting the rotational force applied by the hand-tightening nut 210 into an axial clamping force, pressing the fixed clamp 206 and the manhole fastening hinge seat 204, ensuring that the manhole cover 203 remains stable under high pressure or vibration environment.

[0029] Furthermore, one side of the hand-tightening nut 210 is in contact with the fixed clamp 206. The hand-tightening nut 210 forms a sliding structure with the movable fastening bolt 209 through the handle 211. With the setting of the hand-tightening nut 210, the hand-tightening nut 210 engages with the thread of the movable fastening bolt 209 by rotation, converting the helical force into axial clamping force, and firmly pressing the manhole cover 203 onto the manhole base 202, thereby ensuring that the manhole seal 205 achieves a reliable seal. At the same time, the hand-tightening nut 210 adopts a manual operation design and is equipped with a handle 211, which can quickly tighten and loosen the manhole cover 203 without additional tools, simplifying the operation steps and improving work efficiency.

[0030] Furthermore, the manhole cover 203 is fixed to the manhole base 202 via the manhole cover opening and closing trunnion 208 and the movable fastening bolt 209. Through the setting of the manhole cover opening and closing trunnion 208, the manhole cover 203 is mechanically connected to the manhole base 202 to form a rotatable opening and closing structure, which allows the manhole cover 203 to open and close flexibly with the trunnion as the fulcrum, avoiding the cover from completely detaching and causing loss or damage. At the same time, the manhole cover opening and closing trunnion 208 provides a rotation fulcrum for the opening and closing of the manhole cover 203, which makes it convenient for users to quickly open or close the manhole cover 203 during operation, while reducing the complexity of operation and labor intensity.

[0031] Working principle: The manhole base 202 is fixedly connected to the main cylinder 1 of the dyeing machine to form a fixed sealing base. The manhole seal 205 is located at the bottom of the manhole cover 203 and is installed on the inner side of the manhole cover 203. It ensures airtightness and liquid tightness after fitting with the manhole base 202 to prevent dyeing liquid leakage. When it is necessary to open, operate the handle 211 to loosen the hand-tightening nut 210, so that the movable fastening bolt 209 is disengaged from the fixed clamp 206. Then, use the manhole cover handle 207 to pull the manhole cover 203 and rotate it to the open position through the manhole cover opening and closing trunnion 208. When closing, rotate the manhole cover 203 to the aligned position to ensure that the manhole seal 205 fits with the manhole base 202. Then tighten the hand-tightening nut 210 to lock the movable fastening bolt 209 and complete the sealing operation. At the same time, the manhole safety handle 201 is installed on the surface of the main cylinder 1 of the dyeing machine for convenient and quick inspection and operation.
