Cabinet door locking device for ship electrical cabinet

Abstract

The invention discloses a cabinet door locking device for a marine electrical cabinet. The marine electrical cabinet comprises a cabinet body and a cabinet door. The marine electrical cabinet comprises a lock box, a gear, an operating handle, an upper lock rod, a lower lock rod and an operating handle control mechanism, the lock box is fixed in the middle of one side of the cabinet door far away from a longitudinal frame of the cabinet body, the gear is positioned in the lock box and fixed onto a gear shaft, the gear shaft is supported on a gear shaft seat, one end of the gear shaft facing the operating handle penetrates one side of the cabinet door backing a cabinet body cavity, the operating handle is fixed to one end of the gear shaft, the upper lock rod is matched with a pair of upper lock rod guide rails, an upper cylinder is arranged at the upper end of the upper lock rod, an upper lock rod rack is arranged at the lower end of the upper lock rod, the lower lock rod is matched with a pair of lower lock rod guide rails, a lower cylinder is arranged at the lower end of the lower lock rod and matched with a lower latch in a bolted manner, the lower latch is fixed to a lower frame of a cavity opening, a lower lock rod rack is arranged at the upper end of the lower lock rod, and the operating handle control mechanism is arranged on the cabinet door and matched with the operating handle. Anti-corrosion requirements are met, the cabinet door locking device is durable in use, reliable, good in safety and convenient to operate in a bare-handed manner, and the structure is simplified.

Description

technical field [0001] The invention belongs to the technical field of auxiliary components of electrical equipment, and in particular relates to a door locking device of an electrical cabinet for ships. Background technique [0002] The ships mentioned above mainly refer to seagoing ships, such as dry bulk carriers (also called "bulk carriers"), tankers, product oil tankers, general cargo ships, container ships, liquefied gas carriers, refrigerated ships and barges, etc. Wait. These ships are usually equipped with electrical cabinets and the cabinet body of the electrical cabinet is equipped with a cabinet door, and the cabinet door is locked with the cabinet body by a locking device or unlocked as required. The self-evident function of the cabinet door is to ensure safety; to protect the electrical components arranged in the cabinet. The locking reliability of the locking device, the convenience of opening and closing, and the simplicity of the structure are important fa...

Problems solved by technology

[0004] Typical such as the "rack and pinion automatic locking mechanism" recommended by CN101260759B, this patent adopts a rack and pinion structure, so it can objectively reflect the technical effect recorded in paragraph 0005 of its specification, but there are still the following shortcomings: 1. As mentioned above, under normal circumstances, because the personnel on the ship are all specific personnel, there are almost no situations where non-ship personnel or outsiders come in and out. The locking device is often not equipped with a lock with a lock cylinder that relies on the key to open, because the ship sails In the ocean, the salt content in the sea air is high, which is easy to corrode the lock cylinder, making it impossible to open or lock. However, because the patent is equipped with a lock cylinder that can be opened by a key, it is suitable for the design of the electrical cabinet door for ships. The structure of the locking device is not instructive; secondly, because the locking device of this patent does not have a handle for the operator to hold and pinch, it needs to install a handle on the cabinet door separately, thus resulting in a complicated structure; thirdly, due to the The energy storage elastic part is essentially a spring, and because the fatigue resistance of the spring is relatively weak, after a period of use, the life of the entire locking device will be affected as the effect continues to decline
