Lamp case frame
Technical field
The utility model relates to Lamp case frame.
Background technology
The existing lamp box being suspended on a head, mainly comprises framework and the illuminating lamp that is arranged on framework the inside.Framework adopts thin-wall stainless steel to be welded mostly.Thin-wall stainless steel intensity is limited, easily damages, and can not again utilize after the replacing of the Lamp case frame of this structure.
Summary of the invention
The Lamp case frame that the purpose of this utility model is to provide that a kind of assembly and disassembly are convenient and swift, intensity is high, can again utilize after long service life, dismounting.
This Lamp case frame, it comprises rectangle bracing frame, the framework being formed by connecting by upper and lower, left and right frame, upper and lower, left and right frame is section bar, and upper side frame is made up of front upper, rear upper two section bars; The front end of rear upper sectional material has arc-shaped slot and is positioned at the limit base of arc-shaped slot upper inside wall, the upper rear end of front upper sectional material has can stretch into the upset portion rotating in arc-shaped slot and along arc-shaped slot inwall, is subject to the restriction of limit base while contacting and can not be rotated further when upset portion turns to limit base; Four right-angle connectors lay respectively at the rectangle interior angle place of front upper sectional material, left and right side frame, lower frame composition; Front upper sectional material, left and right side frame, lower frame are all connected by screw with right-angle connector; Two support bars up and down of bracing frame are connected with rear upper sectional material, lower frame by screw respectively.
Above-mentioned Lamp case frame, lower frame is made up of front lower, rear lower two section bars that are connected by screw; Described four right-angle connectors lay respectively at the rectangle interior angle place of front upper sectional material, left and right side frame, front lower sectional material composition; Front upper sectional material, left and right side frame, front lower sectional material are all connected by screw with right-angle connector; The lower support bar of bracing frame is connected with rear lower sectional material by screw.Lower frame is made up of front lower, rear lower two section bars that are connected by screw, has further reduced the difficulty of assembling or dismounting.
Above-mentioned Lamp case frame, the rear portion of front lower sectional material has the rear plate that level extends back, and the front portion of rear lower sectional material has the front flat board of horizontal forward extension; Described connection screw front lower, rear lower two section bars is connected on rear plate and front flat board.Like this, connect front lower, rear lower two section bars convenient.
The beneficial effects of the utility model: because upper and lower, left and right frame is section bar, so intensity is high; Because limit base can rotate in arc-shaped slot, thus assembling, convenient disassembly; Front upper sectional material, left and right side frame, lower frame are all connected by screw with right-angle connector, and time for convenience detach, the section bar after dismounting can utilize again.

Detailed description of the invention
Referring to the Lamp case frame shown in Fig. 1-4, it comprises rectangle bracing frame 6, the framework 5 being formed by connecting by upper and lower, left and right frame.
Upper side frame 1 is made up of front upper sectional material 11, rear upper sectional material 12.The front end of rear upper sectional material has arc-shaped slot 121 and is positioned at the limit base 122 of arc-shaped slot upper inside wall.The upper rear end of front upper sectional material has can stretch into the upset portion 111 rotating in arc-shaped slot and along arc-shaped slot inwall.Be subject to the restriction of limit base and can not be rotated further when upset portion turns to while contacting with limit base.
Lower frame 4 is made up of front lower sectional material 41, rear lower sectional material 42.The rear portion of front lower sectional material has the rear plate 411 that level extends back, and the front portion of rear lower sectional material has front dull and stereotyped 421 of horizontal forward extension.Screw 71 is connected front lower sectional material, rear lower sectional material with front flat board through rear plate.
Left frame is left profile 2, and left frame is right profile 3.
Four right-angle connectors 8 lay respectively at the rectangle interior angle place of front upper sectional material, left profile, right profile, front lower sectional material composition; Front upper sectional material, left profile, right profile, front lower sectional material are all connected by screw 72 with right-angle connector.
Upper support bar 61, lower support bar 62 bars of bracing frame are connected with rear upper sectional material, rear lower sectional material by screw (not shown) respectively.
