The present invention will be further described in detail for example.It should be appreciated that specific embodiment described herein is only used for explaining this
Utility model is not used to limit the utility model.
Electric heater housing as shown in Figures 1 to 5, multiple mounting plates 1 including surrounding hollow structure jointly are two neighboring
The mounting plate 1 is detachably connected by holding section, reduces screw number when assembling using holding section, it is multiple that structure is effectively reduced
Miscellaneous degree to effectively shorten assembly time, and can effectively avoid shadow caused by due to screw gets rusty or installs unqualified
It rings, increases the reliability of electric heater housing.
Holding tank, another mounting plate 1 are provided on a mounting plate 1 in the two neighboring mounting plate 1
Edge protrude into and form the holding section in the holding tank, during installation, edge is inserted into holding tank, makes edge and accommodates
Slot interference fit is completed to be connected together.
The part mounting plate 1 forms L-shaped structure 2 to twice bended inside the hollow structure, the L-shaped structure 2 with
The holding tank is formed between the mounting plate 1, in interference fit, the edge of mounting plate 1 is extruded in correspondence by L-shaped structure 2
Mounting plate 1 on, to guarantee the reliability that is connected together, wherein L-shaped structure 2 includes first segment and second segment, described first
The width of section is less than the width of second segment, and first segment is vertical with mounting plate 1, and second segment is parallel with mounting plate 1, and the width of first segment
Degree is equal to or slightly less than the edge thickness of the mounting plate 1 matched.
The end of the mounting plate 1 folds over to form reinforcement part to the mounting plate 1, and the L-shaped structure 2 is set to institute
It states on reinforcement part, increases the structural strength of holding section position.
