Underwater operation lamp shell

Abstract

The invention discloses an underwater operation lamp shell which comprises a lamp tube, a head cap assembled at the front part of the lamp tube and a tail cap assembled at the rear part of the lamp tube; the outer wall surface of the front end of the tail cap is provided with a round of tail cap steps which are locked with the lamp tube; each tail cap step is provided with a tail cap sealing slot; the outer wall surface of the front end of the lamp tube is provided with a round of lamp tube steps which are locked with the head cap; each lamp tube step is provided with a lamp tube sealing slot; sealing rings are arranged in the tail cap sealing slots and the lamp tube sealing slots; and when the locking of the head cap, the lamp tube and the tail cap is not fully sealed, at least two layers of sealing ring deformation spaces are longitudinally divided between the sealing rings and the tail cap and the end surface of the lamp tube and between the sealing rings and the lamp tube and the end surface of the head cap. The invention provides the underwater operation lamp shell which has simple structure and low cost and can achieve submersible 30m IP68 protection grade.

Description

technical field [0001] The invention belongs to the technical field of lighting lamps, and relates to a lamp shell, in particular to an underwater working lamp shell. Background technique [0002] Some hand-held lamps are used for underwater operations, and they need to reach at least the protection level of IP68 for diving 30 meters. Most underwater operations use diving lights. However, in order to achieve a higher sealing effect underwater, the existing diving lights often use Complicated structure and fine cooperation to achieve sealing, complex structure and fine cooperation make the price of diving lights more expensive, and to achieve the sealing effect, the sealing parts of diving lights are generally thick and wide, and the corresponding parts of diving lights are also enlarged, resulting in diving The weight of the light is relatively heavy, and it is not conducive to underwater operation when the hand-held operation is performed.

Problems solved by technology

[0002] Some hand-held lamps are used for underwater operations, and they need to reach the protection level of IP68 for diving at least 30 meters. Most underwater operations use diving lights. However, in order to achieve a higher sealing effect underwater, the existing diving lights often use Complicated structure and fine cooperation to achieve sealing, complex structure and fine cooperation make the price of diving lights more expensive, and to achieve the sealing effect, the sealing parts of diving lights are generally thick and wide, and the corresponding parts of diving lights are also enlarged, resulting in diving The weight of the lamp is relatively heavy. When working in hand, the heavy lamp is not conducive to underwater operation.

There are also some simple waterproof lamps, which are sealed by setting a sealing ring at the joint. The lamp shell with this sealed structure cannot meet the underwater sealing performance requirements and cannot be used for underwater operations.
