DETAILED DESCRIPTION

[0038] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0039] Please refer to Figures 1-9The utility model provides a kind of technical scheme: a good sealing outdoor door offshore cabinet, including cabinet frame 1, the left and right sides and top of cabinet frame 1 are fixedly installed with support seat 2, the section of support seat 2 is in the form of "U" letter type structure design, polyurethane sealing paste 3 is attachedly installed on the surface of support seat 2, the compression ratio of polyurethane sealing paste 3 is greater than or equal to 50%, the outside of left and right polyurethane sealing paste 3 is attachedly connected with side plate 4, the top surface of top polyurethane sealing paste 3 is attachedly connected with top plate 5, side plate 4 and top plate 5 are fixedly connected with cabinet frame 1 by connecting screw, the top of cabinet frame 1 on the two sides of top plate 5 is symmetrically installed with lifting ring screw 6, structure glue sealing is made around after lifting ring screw 6 is connected with cabinet frame 1, the inside left and right sides of cabinet frame 1 are symmetrically installed with mounting plate 7, mounting hole 8 is formed in the inside of mounting plate 7, and mounting hole 8 is formed in the inside of mounting plate 7 with equal interval;

[0040] The design of the above structure makes the side plate 4 and the top plate 5 generate pressure on the polyurethane sealing paste 3 when they are fixedly connected with the cabinet frame 1 by connecting screws, so that the polyurethane sealing paste 3 is tightly attached to the side plate 4 and the top plate 5, ensuring the sealing effect of the connection between the side plate 4, the top plate 5 and the cabinet frame 1. The support seat 2 can stably connect the polyurethane sealing paste 3 and the cabinet frame 1. The structure glue is arranged around the connection between the lifting ring screw 6 and the cabinet frame 1 to improve the connection sealing performance. The lifting ring screw 6 is convenient for overall hoisting. The mounting holes 8 with equal intervals on the mounting plate 7 are convenient for installing internal components at different heights, improving the convenience of assembly.

[0041] The cabinet frame 1 is fixedly installed with a connecting seat 9 on the front and back sides, and a three-element ethylene-propylene rubber seal 10 is installed on the outside of the connecting seat 9. The three-element ethylene-propylene rubber seal 10 is fixedly installed with a clamping tooth 11 inside, and a steel ring is arranged inside the three-element ethylene-propylene rubber seal 10. The front and back sides of the cabinet frame 1 are both installed with a hinge assembly 15. The back side hinge assembly 15 is connected with a back cabinet door 12. The top of the back cabinet door 12 is rectangularly arrayed with an upper heat dissipation hole 13. The bottom of the back cabinet door 12 is inlaidly installed with a lower heat dissipation plate 14. The front side hinge assembly 15 is connected with a front cabinet door 16. The inside of the front cabinet door 16 is inlaidly installed with an observation window 17. The bottom of the front cabinet door 16 is inlaidly installed with a bottom heat dissipation plate 18.

[0042] The design of the above structure makes the closed rear cabinet door 12 and front cabinet door 16 closely fit with the EPDM seal 10 when the rear cabinet door 12 and front cabinet door 16 are rotated and closed by the hinge assembly 15, thereby ensuring the connection sealing between the rear cabinet door 12, front cabinet door 16 and cabinet frame 1. The connection seat 9 provides a stable installation position for the EPDM seal 10, and the clamping teeth 11 inside the EPDM seal 10 can increase the friction between the connection seat 9, thereby improving the connection stability of the connection seat 9 and the EPDM seal 10 to prevent falling. The upper heat dissipation hole 13 and lower heat dissipation plate 14 provided on the rear cabinet door 12 and the bottom heat dissipation plate 18 installed at the bottom of the front cabinet door 16 can effectively dissipate heat inside the cabinet, thereby improving the heat dissipation performance.

[0043] The hinge assembly 15 includes a rotating seat 1501 fixedly installed on one side of the front cabinet door 16 and rear cabinet door 12. The rotating seat 1501 is fixedly installed with a connecting shaft 1502 inside. The upper and lower ends of the connecting shaft 1502 are rotatably sleeved with a fixed seat 1503. The fixed seat 1503 is connected with the connecting shaft 1502 between the two ends, and is connected with a limiting ring 1504.

[0044] The design of the above structure makes the rear cabinet door 12 and front cabinet door 16 rotate and open by the rotating seat 1501 to drive the connecting shaft 1502 to rotate inside the fixed seat 1503, thereby limiting the rotation angle of the connecting shaft 1502 by the limiting ring 1504 to avoid the rear cabinet door 12 and front cabinet door 16 from opening too large to collide with the hinge assembly 15, thereby improving the protection effect of the hinge assembly 15.

[0045] A limiting mechanism is connected between the bottom of the front cabinet door 16 and the cabinet frame 1. The limiting mechanism includes a limiting plate 19 fixedly installed on the bottom of the front cabinet door 16. The limiting plate 19 is slidably connected with a connecting plate 20 inside. One end of the connecting plate 20 is rotatably connected with a positioning plate 21. The positioning plate 21 is fixedly connected with the bottom of the cabinet frame 1. The top of the cabinet frame 1 is symmetrically installed with a decorative plate 22. The top of the decorative plate 22 is fixedly installed with a brow plate 23.

[0046] The design of the above structure makes the front cabinet door 16 rotate and open to drive the connecting plate 20 to rotate on the positioning plate 21, and the front end of the connecting plate 20 to slide inside the limiting plate 19, thereby limiting the opening of the front cabinet door 16, and limiting the opening of the opened front cabinet door 16 by the friction between the front end of the connecting plate 20 and the limiting plate 19, thereby effectively avoiding the front cabinet door 16 from opening too large to collide and damage the hinge assembly 15.

[0047] Thus a series of work is completed. The contents not described in detail in the specification belong to the prior art known to those skilled in the art.

[0048] Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement to part of the technical features, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
