Description

Technical Field

[0001] This utility model relates to the technical field of explosion-proof lighting devices, specifically to a quick-connect explosion-proof lighting device for offshore platforms. Background Technology

[0002] Currently, Chinese utility model patent CN212005330U discloses an explosion-proof lamp, including an explosion-proof housing, an explosion-proof cover, a lens, tempered glass, a sealing ring, and a lamp panel. The technical effect of this utility model is that it increases the thickness of the explosion-proof housing, enhances the sealing performance between the explosion-proof housing and the explosion-proof cover, greatly enhances the explosion-proof effect of the explosion-proof lamp, and improves the safety of explosion-proof lamp operation.

[0003] Traditional offshore platform lighting fixtures mostly use screw fastening. This method requires a significant amount of time and effort to tighten each screw individually during installation, making it cumbersome and inefficient. Similarly, removing the screws is time-consuming and labor-intensive during maintenance or replacement. Furthermore, the strong vibrations of the marine environment can easily loosen the screws, causing the fixture to shift or even fall, severely impacting lighting performance and operational safety. In addition, while some welding or riveting fixtures offer higher stability, once a fixture malfunctions, it is almost impossible to disassemble and repair it individually; the entire fixture must be replaced, resulting in wasted resources and increased costs. Moreover, given the limited space on an offshore platform, the complex installation and disassembly process further restricts the operator's working space, exacerbating the operational difficulties. Utility Model Content

[0004] Technical problems to be solved

[0005] In view of the above-mentioned shortcomings of the existing technology, this utility model provides a quick-connect explosion-proof lighting fixture for offshore platforms, which can effectively solve the problem that disassembling screws is also time-consuming and laborious when maintaining or replacing lighting fixtures.

[0006] Technical solution

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] This utility model provides a quick-connect explosion-proof lighting fixture for offshore platforms, including a mounting frame, a lighting fixture fixed within the mounting frame, and a connecting assembly disposed at the bottom of the mounting frame. The bottom of the mounting frame has a connecting hole. The connecting assembly includes a connecting end and an insertion end. The connecting end is fixed within the connecting hole, and the insertion end is fixed to the platform. The connecting end includes an integral structure of a connector, a rod, and a locking end. The rod is disposed in the middle of the connector and the locking end, and the locking end has a frustum-shaped structure that is larger at the top and smaller at the bottom. The insertion end includes a threaded rod and a locking head integrally fixed to the top of the threaded rod. The locking head has a slot in the middle, and a spring is fixed to the top of the slot. The bottom of the spring is inclined towards the middle of the bottom end to form an outer probe, which engages with the top of the locking end.

[0009] Furthermore, the diameter of the rod is smaller than the top diameter of the locking end and the diameter of the connector, and the connector is welded and fixed inside the connecting hole.

[0010] Furthermore, the mounting bracket has three sets of connection holes.

[0011] Furthermore, the cavity has a convex structure, and the top of the outer probe is fixed to the top of the locking head; the outer probe has an L-shaped structure.

[0012] Furthermore, a hexagonal nut is fixed to the outer side of the locking head.

[0013] Furthermore, multiple sets of springs are fixed at equal intervals at the top of the locking head, and the inner diameter of the springs is adapted to the inner diameter of the top of the locking head.

[0014] Beneficial effects

[0015] The technical solution provided by this utility model has the following advantages compared with the known public technology:

[0016] This utility model, through its designed connecting component structure, allows users to connect and secure the mounting bracket structure with the connecting end to the insertion end structure fixed on the platform. Compared to the existing threaded structure, the snap-fit ​​connection method eliminates the need for tools to tighten or loosen screws, greatly saving installation and disassembly time and improving work efficiency. It is particularly suitable for offshore platform environments where frequent lamp replacement or maintenance is required.

[0017] In this device, a spring structure is used, in which the rod and locking end are locked and fixed to the slot and the spring. The rod can be inserted into the slot, and the frustum-shaped locking end is locked and fixed to the inclined spring. Multiple sets of spring structures on the outside are used to lock and connect the top of the locking end to the outer protrusion of each set of springs, fixing the mounting frame on the platform. The platform and the insertion end are fixed by threads between the insertion end and the platform. This device is suitable for most existing pre-set hole positions and is convenient for on-site installation. Attached Figure Description
