Abstract
The utility model discloses a flameproof shell comprising a flameproof wallboard and a junction box arranged on the flameproof wallboard, wherein the junction box is provided with a plurality of wiring holes, and communicating joints which are communicated with the wiring holes are fixedly welded on the outer wall of the junction box in which all the wiring holes are positioned. The embodiment has the advantage of simplifying the integral structure, the communicating joints can be made of round steel or steel tubes without adopting t40 or above thick steel plates, and the flameproof shell is easy in processing and lower in cost, and saves time, labor and materials.
Description
Technical field
The utility model belongs to shell mechanism manufacturing technology field, is specifically related to a kind of flame-proof type shell.
Background technology
The structure of terminal box on the flame-proof mine shell, many manufacturing enterprises adopt Fig. 1 to mode processing and manufacturing shown in Figure 3 for many years.
This kind mode is specifically: see Fig. 1 and Fig. 2, be provided with terminal box (2) on the flame proof wallboard (1) of flame-proof mine shell, the side of described terminal box is provided with a plurality of screws (5) that cable is introduced that are used for; The concrete shape of described screw is seen Fig. 2 and Fig. 3, the shortcoming of this kind structure is: in order to guarantee fail safe, the described steel plate that is used to mill out screw need adopt the steel plate more than or equal to t40, take material and not attractive in appearance, in addition since the link cover of FIG flange owing to can produce blind hole, need thickening, it is many and comparatively heavy to take material, and processing technology is poor.So the structure of the traditional flame-proof mine shell of this kind is still needed improvements badly.
Summary of the invention
The purpose of this utility model provides the flame-proof type shell that a kind of finished product processing is easy and effectively reduce cost.
The technical scheme that realizes the utility model purpose is:
The utlity model has positive effect: a kind of flame-proof type shell, comprise flame proof wallboard and the terminal box that is arranged on the flame proof wallboard, described terminal box is provided with a plurality of wiring holes; Be welded with the communicating joint that is communicated with this wiring hole on the terminal box outer wall at described each wiring hole place.
Described each communicating joint adopts round steel or steel pipe to be processed into.
Described each communicating joint is provided with the wiring vestibule, and described wiring vestibule edge direction from outside to inside comprises internal threaded regions and ladder porose area successively.
Described each communicating joint outer wall is provided with the positioning area that is used to insert wiring hole on the terminal box.
End edge near terminal box of described positioning area is set as chamfering or fillet shape, and the crack on described chamfering or fillet shape outer wall and the described terminal box between the corresponding wiring hole hole wall is as the weld zone.
(1) in the utility model, be welded with the communicating joint that is communicated with this wiring hole on the terminal box outer wall at described each wiring hole place, the advantage of present embodiment is to simplify overall structure, and described communicating joint can adopt round steel or steel pipe to make, need not to adopt again steel plate to make more than or equal to t40, handling ease and cost are lower, time saving and energy saving material-saving.
(2) in the utility model, when communicating joint many and when close, can be on communicating joint chamfering or fillet, in interior welds, promptly adopt the frame mode of " the end edge near terminal box of described positioning area is set as chamfering or fillet shape; the crack on described chamfering or fillet shape outer wall and the described terminal box between the corresponding wiring hole hole wall is as the weld zone ", this structure outward appearance does not on the one hand have weld seam, and is comparatively attractive in appearance yet; On the other hand, this kind structure can make the terminal box flange wall adopt thin steel plate to make, and is through hole processing, and processing technology is more or less freely and reliable and stable.
