[0025] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] In the description of the present application, it should be understood that the terms "upper", "lower", "left", "right", "middle", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0027] like Figure 1-7As shown, the utility model provides a rapid opening and closing structure of a power station inspection door, comprising a latch assembly, an outer frame 1 of the power station, and an inspection door 2. The front side of the outer frame 1 is provided with an inspection port 11, and the inspection door 2 is arranged outside the inspection port 11 to close or open the inspection port 11, and the inspection door 2 is easy and fast to open. An inspection compartment 12 is provided inside the outer frame 1, and the inspection port 11 is connected to the inspection compartment 12. After opening the inspection door 2, the staff can reach into the inspection compartment 12 from the inspection port 11 to perform maintenance and inspection work.

[0028] Specifically, one side of the inspection door 2 is rotatably arranged on one side of the inspection opening 11, so that the inspection door 2 can be rotated and opened and closed relative to the inspection door 2, and the latch assembly can lock the inspection door 2, and it is also convenient to unlock the inspection door 2. The latch assembly includes a lock tongue 3 and a clamping lock body 4. The lock tongue 3 is arranged on the other side of the inspection door 2, and the clamping lock body 4 is correspondingly arranged on the other side of the inspection opening 11. The clamping lock body 4 is provided with an elastic member 44, and the elastic member 44 provides a clamping force for the clamping lock body 4, pushing the inspection door 2 inward, and the inspection door 2 rotates. When the inspection opening 11 is closed, the lock tongue 3 is inserted into the clamping lock body 4, and the clamping lock body 4 is first opened by the elastic member 44 to allow the lock tongue 3 to be inserted. After the lock tongue 3 is inserted, the lock tongue 3 is clamped by the resetting action of the elastic member 44, thereby locking the inspection door 2. In the absence of external force, the inspection door 2 will not be opened; because the clamping lock body 4 is provided with a clamping force by the elastic member 44, when the lock tongue 3 is pulled outward, the force of the lock tongue 3 moving outward easily pushes the clamping lock body 4 to open, thereby disengaging from the clamping lock body 4, opening the inspection door 2, and performing necessary maintenance and inspection work. The utility model can quickly and flexibly open and close the inspection door 2, and the operation of opening and closing the inspection door 2 is simple, which simplifies the inspection process, improves work efficiency, and makes maintenance work easier and faster.

[0029] Key References Figure 5-7The clamping lock body 4 includes a clamping seat 41, an upper clamping arm 42, a lower clamping arm 43, and an elastic member 44. The upper clamping arm 42 and the lower clamping arm 43 are both rotatably arranged on the clamping seat 41, and the elastic member 44 is connected between the upper clamping arm 42 and the clamping seat 41, and between the lower clamping arm 43 and the clamping seat 41. The upper clamping arm 42 and the lower clamping arm 43 are relatively arranged. When the elastic member 44 is in a natural state, a locking cavity 45 with an opening is formed between the upper clamping arm 42 and the lower clamping arm 43. The locking tongue 3 cooperates with the locking cavity 45, and the locking tongue 3 is inserted into the locking cavity 45 and clamped by the upper frame arm and the lower clamping arm 43. Specifically, the shape and size of the lock tongue 3 are consistent with the locking cavity 45, and the cross-sectional shape of the lock tongue 3 is elliptical. The width of the middle part of the lock tongue 3 is greater than the width of the opening of the locking cavity 45. When the lock tongue 3 is inserted into the locking cavity 45, the lock tongue 3 pushes the upper clamping arm 42 and the lower clamping arm 43 to rotate and open, and the elastic member 44 is compressed. When the lock tongue 3 is fully inserted into the locking cavity 45, the elastic member 44 resets and pushes the upper clamping arm 42 and the lower clamping arm 43 to rotate and close to clamp the lock tongue 3, and the clamping state is maintained to lock the inspection door 2. The cross-sectional shape of the lock tongue 3 is elliptical, and its upper and lower sides are arc-shaped. When the lock tongue 3 moves toward the locking cavity 45, it can easily enter the opening of the locking cavity 45.

[0030] Furthermore, the upper clamping arm 42 and the lower clamping arm 43 have the same shape, one end of both is a connecting portion 421, and the other end is an arc-shaped clamping portion 422. The connecting portion 421 is rotatably arranged on the clamping seat 41. Specifically, a rotating shaft 46 can be arranged in the middle of the clamping seat 41, and the connecting portion 421 is rotatably arranged on the clamping seat 41 through the rotating shaft 46; a locking cavity 45 is formed between the two arc-shaped clamping portions 422, and an elastic member mounting portion 423 parallel to the clamping seat 41 is extended outwardly of the arc-shaped clamping portion 422, and the two ends of the elastic member 44 are respectively connected to The clamp seat 41 and the elastic member mounting portion 423 are connected, and the elastic member 44 is preferably a spring. Springs are abutted between the two ends of the clamp seat 41 and the two elastic member mounting portions 423. Mounting columns can be set on the clamp seat 41 and the elastic member mounting portion 423 to install the spring. When the inspection door 2 is closed, the spring is stretched to push the arc-shaped clamping portion 422 to clamp the lock tongue 3. When the inspection door 2 is opened, the two arc-shaped clamping portions 422 are pushed open by the lock tongue 3, and the spring is compressed. After the lock tongue 3 is completely out of the locking cavity 45, the spring will push the arc-shaped clamping portion 422 to return to its original position.

The clamp seat 41 can be fixed to the mounting plate 47 by bolts. The mounting plate 47 can also be fixed to the side wall of the inspection bin 12 by bolts, or can be welded and fixed to the side wall of the inspection bin 12. The lock tongue 3 is vertically fixed to the inner side of the inspection door 2 through another mounting plate 47. The lock tongue 3 can be integrally connected with the mounting plate 47, and the mounting plate 47 is fixed to the inspection door 2 by bolts. When the inspection door 2 closes the inspection port 11, the lock tongue 3 can extend into the clamping lock body 4 in the inspection bin 12, the latch assembly is not exposed, and the inspection door 2 can completely close the inspection port 11.

[0032] Key References Figure 4 , a plurality of limit plates 5 are provided on the other side of the inspection opening 11, and the limit plates 5 are located at the front side of the clamping lock body 4. When the inspection door 2 is closed so that the clamping lock body 4 clamps the lock tongue 3, the other side of the inspection door 2 abuts against the limit plates 5. When the lock tongue 3 is just locked, the limit plates 5 can limit the inspection door 2 from rotating inwards, preventing the lock tongue 3 from excessively colliding with the clamping lock body 4, thereby reducing the loss of the lock. Specifically, two limit plates 5 can be provided, which are respectively located above and below the clamping lock body 4, and the limit plates 5 can also be welded to the side wall of the inspection compartment 12 near the inspection opening 11.

[0033] Key References Figure 1 A hand opening 21 is provided on the outer side of the inspection door 2 near the lock tongue 3, and the hand opening 21 is for a hand to be inserted into to grasp the inspection door 2, so that the hand grasps the inspection door 2 and applies force outward to pull the inspection door 2, making it more convenient to open the inspection door 2.

[0034] Key reference Figure 2 and Figure 3 A hinge 6 is provided on one side of the inspection opening 11, and the hinge 6 can be fixed on the side of the outer frame 1 close to the inspection opening 11 by bolts or welding. A hinge rotating piece 7 is fixed on one side of the inspection door 2, and the hinge rotating piece 7 can be welded and fixed on the inner side of the inspection door 2. The hinge rotating piece 7 is rotatably arranged on the hinge 6 so that one side of the inspection door 2 is rotatably connected to the inspection opening 11, and the opening and closing of the inspection door 2 is more flexible.
