[0019] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0020] like Figure 1 , Figure 2 As shown, the cabinet with good sealing performance provided by the embodiment of the present application comprises a door frame 1 and a door 2 connected to the door frame 1 by a hinge, the door frame 1 is provided with at least one material discharge area, each material discharge area is provided with a sealing ring 3 on the outside, one side of the door 2 is hinged to the door frame 1, and the other side of the door 2 is provided with a door 2 lock. Figure 3 and Figure 4 As shown, at least one oblique lifting block 5 is provided at the lower end of the door 2, and the door 2 lock includes a lock frame 41 provided on the inner side of the door 2, a No. 1 lock bar 42 and a No. 2 lock bar 43 respectively connected to the two sides of the lock frame 41 in a sliding manner, a lock core 44 provided in the lock frame 41 for driving the No. 1 lock bar 42 and the No. 2 lock bar 43 to rise and fall, a No. 1 guide block 45 provided on the inner side of the door 2 for guiding the No. 1 lock bar 42 and a No. 2 guide block 46 provided for guiding the No. 2 lock bar 43, and a plurality of No. 1 door buckles 47 and No. 2 door buckles 48 with the notches upward are provided on the door frame 1. Figure 5 As shown, the first lock bar 42 is provided with a first cross bar 49 which can be inserted into the first door buckle 47, and the second lock bar 43 is provided with a second cross bar which can be inserted into the second door buckle 48. The upper end of the first lock bar 42 corresponds to the upper end of the door frame 1, and the lower end of the second lock bar 43 corresponds to the lower end of the door frame 1.

[0021] In actual use, when the door 2 is closed, the sealing ring 3 is squeezed by the inner side of the door 2, so that the sealing ring 3 forms a seal between the door 2 and the door frame 1. At the same time, when the door 2 is closed, if the hinge sinks, the oblique lifting block 5 will lift the door 2 when it contacts the door frame 1, so that the door 2 and the door frame 1 are closed. After the door 2 and the door frame 1 are closed, the lock core 44 drives the first lock bar 42 to rise and the second lock bar 43 to fall, so that the first cross column 49 extends into the first door buckle 47, and the second cross column extends into the second door buckle 48.

[0022] In the above design, the No. 1 lock strip 42 and the No. 2 lock strip 43 can ensure that the connection force is effectively and evenly applied to the opening and closing sides of the door 2 and the door frame 1, which can ensure good sealing performance between the door 2 and the door frame 1 and good constant temperature performance of the electronic devices in the door frame 1.

[0023] Specifically: Figure 6 As shown, the No. 1 door catch 47 and the No. 2 door catch 48 have the same structure. The No. 1 door catch 47 includes a No. 1 plate 471 fixedly arranged on the front side of the door frame 1, a No. 1 left plate 472 and a No. 1 right plate 473 respectively arranged on the No. 1 plate 471, the No. 1 left plate 472 and the No. 1 right plate 473 form a No. 1 vertical groove 401 for avoiding the No. 1 lock strip 42, the No. 1 left plate 472 is provided with a No. 1 notch A402 for accommodating the left end of the No. 1 horizontal column 49, and the No. 1 right plate 473 is provided with a No. 1 vertical groove 401 for accommodating the right end of the No. 1 horizontal column 49. No. 1 slot B403, the openings of the No. 1 slot A402 and the No. 1 slot B403 are downward, the No. 2 door buckle 48 includes a No. 2 plate fixedly arranged on the front side of the door frame 1, a No. 2 left side plate and a No. 2 right side plate respectively arranged on the No. 2 plate, the No. 2 left side plate and the No. 2 right side plate form a No. 2 vertical groove for avoiding the No. 2 lock strip 43, the No. 2 left side plate is provided with a No. 2 slot A for accommodating the left end of the No. 2 horizontal column, the No. 2 right side plate is provided with a No. 2 slot B for accommodating the right end of the No. 2 horizontal column, and the openings of the No. 2 slot A and the No. 2 slot B are upward.

[0024] In actual use, when the door 2 is closed, the No. 1 lock bar 42 extends into the No. 1 vertical slot 401, and the No. 2 lock bar 43 extends into the No. 2 vertical slot, and then the lock core 44 drives the No. 1 lock bar 42 to rise and the No. 2 lock bar 43 to descend, so that the two ends of the No. 1 cross column 49 extend into the No. 1 slot A402 and the No. 1 slot B403 respectively, and the two ends of the No. 2 cross column extend into the No. 2 slot A and the No. 2 slot B respectively. When the door 2 needs to be opened, the lock core 44 drives the No. 1 lock bar 42 to descend and the No. 2 lock bar 43 to rise, so that the two ends of the No. 1 cross column 49 extend out of the No. 1 slot A402 and the No. 1 slot B403 respectively, and the two ends of the No. 2 cross column extend into the No. 2 slot A and the No. 2 slot B respectively.

[0025] In the above design, the structural design of the No. 1 door catch 47 and the structural design of the No. 2 door catch 48 can effectively realize the clamping of the No. 1 horizontal column 49 and the No. 2 horizontal column, ensuring the locking and quick unlocking of the door 2 lock to the door 2 and the door frame 1.

[0026] Specifically: Figure 4 As shown, the lock frame 41 is provided with a No. 1 slide groove slidably connected to the No. 1 lock bar 42 and a No. 2 slide groove slidably connected to the No. 2 lock bar 43, the No. 1 lock bar 42 is provided with a plurality of No. 1 through holes 420 along the extension direction, the No. 2 lock bar 43 is provided with a plurality of No. 2 through holes 430 along the extension direction, the lock core 44 includes a rotating part 441 rotatably connected to the lock frame 41 and a plurality of protrusions 442 circumferentially arranged on the rotating part 441, one of the No. 1 through hole 420 and the No. 2 through hole 430 can be simultaneously engaged with different protrusions 442.

[0027] In actual use, when the lock core 44 rotates clockwise, the protrusion 442 drives the No. 1 lock bar 42 upward and the No. 2 lock bar 43 downward; when the lock core 44 rotates counterclockwise, the protrusion 442 drives the No. 1 lock bar 42 downward and the No. 2 lock bar 43 upward; when the lock core 44 is stationary, the protrusion 442 extends into the corresponding No. 1 through hole 420 and No. 2 through hole 430 to fix the No. 1 lock bar 42 and the No. 2 lock bar 43.

[0028] In the above design, the structural design and specific implementation of the lock frame 41 facilitate the lifting and fixing of the No. 1 lock bar 42 and the No. 2 lock bar 43.

[0029] Specifically: Figure 2 As shown, the door 2 includes a body 21 and a partition frame 22 arranged on the inner side of the body 21, and thermal insulation cotton is arranged in the partition frame 22.

[0030] In the above design, the door 2 can be effectively insulated by providing thermal insulation cotton, ensuring that the electrical components in the door frame 1 are kept at a constant temperature.

[0031] Specifically: Figure 3 As shown, the oblique lifting block 5 is provided with an inclined surface 50 which abuts against the door frame 1 , and the inclined surface 50 faces the inner side of the door frame 1 .

[0032] In actual use, if the lower end of the door 2 slightly interferes with the door frame 1 due to the lower side of the hinge, when the door 2 is closed, the inclined surface 50 will abut against the door frame 1. As the door 2 continues to close, the door frame 1 gradually abuts against the lower end of the inclined surface 50, thereby lifting the door 2.

[0033] In the above design, the structural design and specific implementation of the oblique lifting block 5 facilitate closing the door 2.

[0034] To further explain in detail, it should be understood that the above is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
