Description

Ballast box structure

This creation relates to a ballast box structure, and more particularly to a ballast box structure that can greatly improve airtightness and ease of assembly.

With the rapid development of industry, people in the petroleum, chemical, mining and other industries often need to work in dangerous places containing explosive gases. Traditional general lighting fixtures are prone to accidents caused by high heat or electric sparks that come into contact with explosive gases or dust. Explosive explosions, so explosion-proof lighting fixtures have been used more and more widely in these dangerous places, and the variety has also increased.

As shown in FIG. 1 , the conventional explosion-proof lamp 1 is generally provided with a ballast 10 at the same time, and the ballast 10 is accommodated in a casing 11 in a yaw direction, and a lamp set 12 is disposed on the casing. On one side of the body 11, it is customary to accommodate the housing 11 of the ballast 10 in a rectangular cylindrical structure having a hollow state, and a sealing member 13 corresponding to the two ends of the housing 11 is also rectangular. The structure further closes the inside of the casing 11 to complete the internal airtightness. However, since both the casing 11 and the sealing member 13 have a rectangular shape, the structure may cause airtightness to be difficult to handle, resulting in poor airtightness, and There is a lack of assembly.

Therefore, how to solve the above problems and problems in the past, that is, the creators of the case and the relevant manufacturers engaged in this industry are eager to study the direction of improvement.

Therefore, in order to effectively solve the above problems, the main purpose of the present invention is to provide a ballast box structure which can greatly improve airtightness.

The second objective of this creation is to provide a ballast box structure that greatly enhances assembly convenience.

In order to achieve the above object, the present invention provides a ballast box structure, which comprises a casing and at least one sealing member, the casing has a receiving space for accommodating a ballast, and the casing is connected to at least one end of the connecting portion. One end of the set of joints forms a set of interfaces for communicating with the receiving space, and the sealing member is correspondingly combined with the casing, and one end of the sealing member forms a closed portion correspondingly combined in the group interface.

Through the design of the structure of the present invention, the cross-sectional area of the group interface of the assembly portion is circular, and the cross-sectional area of the sealing portion of the sealing member disposed therewith is also circular, so that the assembly portion 211 When combined with the closing portion 241, the airtight effect between the two can be greatly improved, and the inside of the casing 21 can be completely sealed, and assembly convenience can be improved.

As shown in the figure, a ballast box structure includes a casing 2 and at least one. The sealing member 4 has a receiving space 20 for accommodating a ballast 3, and one end of the housing 2 is connected to a plurality of connecting portions 21. In this embodiment, the connecting portion 21 has a first portion. a terminal 22 and a second end 23, the first end 22 forming a set of interfaces 221 and communicating with the receiving space 20; the sealing member 4 is correspondingly combined with the assembly portion 21 of the housing 2, the sealing A closed portion 40 is formed at one end of the member 4, and a plurality of external threads 41 are formed on the outer peripheral side of the closing portion 40, and a plurality of internal threads 222 are formed on the inner peripheral side of the group interface 221 to be screwed with the external threads 41. The seal 4 can be firmly assembled with the assembly portion 21.

In this embodiment, the first end 22 of the connecting portion 21 is correspondingly assembled with the sealing member 4, and the second end 23 of the connecting portion 21 is correspondingly disposed with one end of the housing 2. In other words, the assembly portion 21 is a separate component in the embodiment, and can be fixedly combined with the housing 2 by any combination of snapping, fitting, bonding or locking. The cross-sectional area of the first end 22 of the assembly portion 21 (ie, at the group interface 221) is a circular shape, and the cross-sectional area of the second end 23 is a rectangular shape, and the corresponding The cross-sectional area of the casing 2 connected to the second end 23 is also in a rectangular shape (that is, the casing 2 is a rectangular cylinder in a hollow state), and the other end of the casing 2 is provided with a sealing plate. Correspondingly, the accommodating space 20 is completely closed and closed, and at least one of the arranging cylinders 24 is further connected to the plate body 5 at the connecting portion 21, and the arranging cylinder 24 is used for plural The ballast (not shown) is disposed therein; the ballast box structure further includes a plate body 5 and a cover body 6 having a first side 50 and a first Side 51 of the housing 2 of the corresponding group 50 disposed on the first side And a plurality of holes 52 are formed through the first and second sides 50 and 51 on the left and right sides of the plate body 5; the cover body 6 is correspondingly arranged with the second side 51 of the plate body 5, the cover body The accommodating portion 60 has a plurality of through holes 61. The accommodating portion 60 accommodates at least one illuminating member 80. The through holes 61 correspond to the holes 52 and are passed through the plurality of fixing members 84.
