Abstract
The utility model discloses a durable motor protector for an electric fan, which is convenient for assembly and disassembly and has a fixed structure mainly formed by the joint of the annular groove at the terminal port of the front casing and the flange at the terminal port of the back casing. The durable motor protector for an electric fan overcomes the disadvantage that the present fixed structure with an inverse-buckling bolt is difficult to disassemble and easy to break to cause the motor to be exposed to result in electric leakage or electric shock. The motor protector for an electric fan ensures easy assembly and disassembly without any damage to the fixed structure of the front and the back casings during the process of motor maintenance.
Description
The utility model relates to a kind of electric fan motor protection device, particularly relates to a kind of front and rear casing fixed structure of electric fan motor protection device.
The front and rear casing fixed structure of the motor protection device of the electric fan extensive use of Xiao Shouing generally adopts the left-hand thread mode of sending of inserting in the market.The electric fan of producing as the Electric Fan Factory of Shuande, Guangdong U.S.; a kind of front and rear casing fixed structure of electric fan motor protection device is disclosed; form by fore shell and back cover; four holes are arranged on the fore shell; there are four slotting sending to be complementary on the back cover with the fore shell hole; insert and to have taken left-hand thread with you, front and rear casing sends to match with the hole on the fore shell with left-hand thread by slotting on the back cover and fixes.This inserting sends the shortcoming of left-hand thread fixed structure to be: left-hand thread makes dismounting back cover difficulty, and slotting sending easily fractures when dismounting; Therefore, often when maintenance dismounting back cover, doing slotting the sending of having broken because of carelessness causes back cover to retighten again, not having this unremarkable supporting back cover on the market again sells, motor exposes at one's discretion, cause that electric leakage or child touch danger such as touching electricity, even cause and jeopardize the people life property safety by fire.
The purpose of this utility model is to provide a kind of to be installed and removed conveniently, the front and rear casing fixed structure of long-lived annular groove formula electric fan motor protection device; insert to overcome that to send left-hand thread formula fixed structure difficulty to unload easy to break, minor issue causes the defective of dangerous consequences such as electric leakage or electric shock.
Fig. 1-A is an electric fan motor protection device fore shell front view;
Fig. 1-B is an electric fan motor protection device back cover front view;
Fig. 2 is an electric fan motor protection device stereogram;
Narrate the technical solution of the utility model and embodiment below in conjunction with accompanying drawing: the utility model electric fan motor protection device is matched by fore shell (1) and back cover (2) and constitutes; fore shell has an annular groove (3) or 3 to 8 discontinuous annular grooves is set along port; back cover (2) front port has the edge (4) of projection; when the size of annular groove and raised brim are by chance coincide dismounting; only need take off gently fore shell just can: during installation; only need fore shell is aimed at back cover; annular groove (3) matches with raised brim (4), but buckles just fix tightly gently.
Because fixedly carrying out of front and rear casing by annular groove and the raised brim structure that matches, make very convenient and unlikely damage front and rear casing fixed structure when the maintenance motor is installed and removed protective device, safe and simple.
Claims (3)
1. electric fan motor protection device.Combined fixedly with back cover (2) by fore shell (1) and to form, it is characterized in that: on fore shell (1) port annular groove (3) is arranged, back cover (2) port has raised brim (4), annular groove (3) and raised brim (4) the formation fixed structure that matches.
2. electric fan motor protection device according to claim 1 is characterized in that said annular groove is annular continuous recess.
3. electric fan motor protection device according to claim 2 is characterized in that said annular groove is 3 to 8 discontinuous grooves.
