[0026] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings of the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Unless otherwise defined, the technical terms or scientific terms used herein should be the common meanings understood by people with ordinary skills in the field to which the present invention belongs.

When the absolute position of the described object changes, the relative positional relationship may also change accordingly.
[0028] In existing technologies, noise can still be transmitted through the gaps between the door leaf and the door frame, especially when the seal between the door frame and the door leaf is insufficient. These gaps prevent complete noise isolation, reducing the overall noise reduction effect. This design shortcoming is particularly pronounced in high-noise environments, making it difficult to effectively control noise levels inside the container, impacting the user experience and safety of the container.
[0029] In view of this, the embodiment of the present invention provides a container noise reduction door for a generator set, referring to Figure 1 , including a box body 1, a door frame 2 and a door leaf 3. The door frame 2 is fixed on the box body 1. The door leaf 3 is connected to the door frame 2 by a hinge 201. A door lock is fixed on the door leaf 3. Figures 2 and 3A first bent plate 401, a second bent plate 402, and a third bent plate 403 are fixed between the door frame 2 and the door leaf 3. One side of the first bent plate 401 is fixed to the door frame 2. The remaining portion of the first bent plate 401 has at least a first step, a second step, and a third step. The second bent plate 402 has a fourth step. The riser of the fourth step extends inward with a first flange perpendicular to the riser of the fourth step. The first flange is welded to the tread of the first step. The tread of the fourth step extends inward with a second flange perpendicular to the tread of the fourth step. The second flange is welded to the riser of the second step. The space surrounded by the second bent plate 402 and the first bent plate 401 is filled with fireproof and sound-absorbing cotton. The space surrounded by the second bent plate 402 and the first bent plate 401 forms the column of the door frame 2, supporting the door leaf 3. The space is filled with fireproof and sound-absorbing cotton to reduce noise transmission. One end of the hinge 201 is fixed to the back of the tread of the second step, and the other end of the hinge 201 is fixed to the door leaf 3; a square tube 305 is also fixed to the door leaf 3, and the square tube 305 is located between the kick surface of the second step and the door leaf 3, and a sealing fireproof strip 5 is pasted on the back of the tread of the third step; the kick surface of the third step extends outward with a third flange perpendicular to the kick surface of the third step, and the third bent plate 403 has a fifth step, and the third flange is welded to the tread of the fifth step; the third flange extends inward with a fourth flange perpendicular to the third flange, and a sealing strip 306 is fixed to the inside of the door leaf 3 and at a position corresponding to the fourth flange. When the door leaf 3 is closed, the flange is inserted into the sealing strip 306; the kick surface of the fifth step extends outward with a sixth flange perpendicular to the kick surface of the fifth step, and a sealing fireproof strip 5 is pasted on the surface of the sixth flange facing the door leaf 3.
[0030] By providing multiple bent plates between the door frame 2 and the door leaf 3 to form a multi-layer structure, not only does the door's strength increase, but fireproof and sound-absorbing cotton is also filled between the bent plates, effectively enhancing the sound insulation and reducing the possibility of noise propagating through the gap between the door leaf 3 and the door frame 2. The multi-layer step design also improves the door's sealing performance, further preventing noise transmission.
[0031] In some embodiments, a bracket 302 is fixed on the door leaf 3, and a lock seat 303 is fixed on the door frame 2. The lock seat 303 and the bracket 302 are located on the same vertical line. The locking rod 301 is inserted into the bracket 302, and both ends of the locking rod 301 are located in the lock seat 303. A lock buckle 304 is also fixed on the locking rod 301. A groove for adapting the lock buckle 304 is provided on the door leaf 3. When the lock buckle 304 is buckled in the groove, the lock buckle 304 is used to lock the door leaf 3.
[0032] The locking rod 301 and the lock catch 304 ensure the door leaf 3 is securely closed and prevent noise leakage caused by loosening of the door leaf 3. The alignment design of the bracket 302 and the lock base 303 ensures the precise positioning of the lock catch 304, thereby improving the safety and stability of the door.
[0033] In some embodiments, the groove runs through the door leaf 3, and one end of the groove located in the box body 1 is threadedly connected to the push rod 6. When the lock 304 is buckled in the groove, the push rod 6 pushes the lock 304 away from the groove.
[0034] The push rod 6 is added so that when the lock catch 304 is in the buckle groove, the door leaf 3 can be further locked by the push rod 6 to ensure the safety of use.
[0035] In some embodiments, the first bending plate 401, the second bending plate 402, and the third bending plate 403 are sheet metal bending plates. Using sheet metal bending plates as bending plates ensures the firmness and durability of the overall structure, simplifies the production process, and reduces manufacturing costs.
[0036] In some embodiments, the number of hinges 201 is greater than 3. By increasing the number of hinges 201, especially when the number of hinges 201 is greater than 3, the load bearing capacity of the door leaf 3 is improved, the deformation risk of the door leaf 3 is reduced, and the service life and stability of the door are improved.
[0037] In some embodiments, the number of hinges 201 installed above 1 / 2 of the height of the door leaf 3 is greater than the number of hinges 201 installed below 1 / 2 of the height of the door leaf 3. Installing more hinges 201 in the upper half of the height of the door leaf 3 enhances the fixing effect of the door leaf 3 at important locations, reduces deformation and loosening of the door leaf 3 due to gravity, ensures the tight closure of the door leaf 3, and further improves the sealing and noise reduction effect of the door.
[0038] In some embodiments, the hinges 201 installed at or above 1 / 2 the height of the door leaf 3 are unevenly distributed. This uneven distribution of hinges 201 allows the hinges 201 to more effectively distribute the load on the door leaf 3, further improving the securing effect of the door leaf 3 and preventing noise leakage caused by an irrational distribution of hinges 201. Because the door leaf 3 is relatively heavy, the uneven distribution of hinges 201 results in a denser distribution of hinges 201 at the top of the door leaf 3, preventing sagging and affecting closure.
[0039] In some embodiments, the tread of the first step is flush with the outer surface of the box body 1. The design of the tread of the first step being flush with the outer surface of the box body 1 makes the external connection between the door frame 2 and the door leaf 3 tighter, which not only looks good but also enhances the sealing effect of the door and reduces the possibility of noise leakage from the joint.
[0040] In some embodiments, the door leaf 3 is filled with fireproof and sound-absorbing cotton. Filling the door leaf 3 with fireproof and sound-absorbing cotton not only enhances the sound insulation effect of the door leaf 3, but also provides additional fire protection, thereby improving the safety and durability of the door leaf 3.
[0041] In some embodiments, the door frame 2 is filled with fireproof and sound-absorbing cotton. The fireproof and sound-absorbing cotton filled in the door frame 2 works together with the sound-absorbing cotton inside the door leaf 3 to further enhance the sound insulation effect of the entire door body, reduce the possibility of noise being transmitted from the door frame 2 to the outside, and improve the fire resistance.
[0042] In summary, the utility model provides a noise-reducing container door for a generator set. By disposing multiple bent plates between the door frame 2 and the door leaf 3 to form a multi-layer structure, welding multiple steps to create a plurality of connections, and using sealing fireproof rubber strips 5 to form multiple sealed sound insulation layers, the door's strength is not only improved, but also fireproof and sound-absorbing cotton is filled between the bent plates, effectively enhancing the sound insulation effect and reducing the possibility of noise propagating through the gap between the door leaf 3 and the door frame 2. The multi-layered step design also improves the door's sealing performance, further blocking the transmission of noise. By designing multiple bent plates, filling with fireproof and sound-absorbing cotton, increasing the number and rational distribution of hinges 201, and designing a precise lock 304, the noise-reducing container door effectively solves the problem of noise leakage between the door leaf 3 and the door frame 2 in the prior art, and significantly improves the door's sealing performance, stability, and safety. These measures not only enhance the noise reduction effect of the container, but also improve fire resistance, durability, and production efficiency, providing better protection for the stable operation of the generator set within the container.
[0043] While the present invention has been disclosed above with reference to preferred embodiments, this is not intended to limit the present invention. Persons skilled in the art will readily appreciate that various modifications and variations can be made without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the claims.
