Description

Technical Field

[0001] The invention relates to the field of air-conditioner auxiliary electric heaters and heaters, in particular to an anti-loosening type insulating metal bracket. Background Art

[0002] At present, in the air-conditioning auxiliary electric heater and heater industry, in order to prevent the overly long heating element from being bent and deformed due to heat during long-term power-on operation and touching the internal parts of the physical machine. The existing technical solution is to install a sheet metal bracket in the middle of the heating element. There are two types of sheet metal brackets. One is a sheet metal bracket without insulation performance. One end of the sheet metal bracket is inserted into the heating element, and the other end is locked on the shell with screws. The other is an insulating sheet metal bracket, but there is no infinite structure between the sheet metal and the insulating gasket. When used for a long time, the sheet metal at the gasket position is easy to loosen due to rotation, which causes the heating element to deform and bend. Both of these technical solutions are prone to safety hazards. Summary of the invention

[0003] In order to solve the above problems, the present invention provides an anti-loosening type insulating metal bracket.

[0004] An anti-loosening insulated metal bracket includes a sheet metal part 1 and a sheet metal part 2 made of metal plates, and also includes a circular ceramic washer arranged on the upper end surface of the sheet metal part 1 and locked and fixed by a large flat head self-tapping screw, and a square ceramic washer arranged between the sheet metal part 1 and the sheet metal part 2 and locked in cooperation with the large flat head self-tapping screw.

[0005] The sheet metal part 1 is L-shaped, and a small boss 1 is arranged on the inner side of the bend to cooperate with the square ceramic gasket to play a limiting role.

[0006] The sheet metal part 2 is V-shaped, and a small boss 2 is arranged on the outer side of the bend to cooperate with the square ceramic gasket to play a limiting role.

[0007] The circular ceramic gasket is in the shape of a stepped cylinder, and a circular hole is arranged in the middle thereof for facilitating the insertion of a large flat head self-tapping screw.

[0008] The middle of the square ceramic gasket is a stepped countersunk hole structure, and the square ceramic gasket is respectively provided with a small blind hole 1 and a small blind hole 2 which cooperate with the small boss 1 and the small boss 2 for limiting.

[0009] The beneficial effects of the present invention are: good thermal insulation and separation of sheet metal part one and sheet metal part two are achieved through circular ceramic washers and square ceramic washers, and then small boss one and small boss two are used in conjunction with small blind hole one and small blind hole two to limit the position, thereby reducing looseness caused by rotation and maintaining the stability of the shape of the heating element.

[0016] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below.

[0017] like Figures 1 to 5 As shown, an anti-loosening insulated metal bracket includes a sheet metal part 1 and a sheet metal part 2 made of metal plates, and also includes a circular ceramic washer 3 set on the upper end surface of the sheet metal part 1 and locked and fixed by a large flat head self-tapping screw 5, and a square ceramic washer 4 set between the sheet metal part 1 and the sheet metal part 2 and locked with the large flat head self-tapping screw 5.

[0018] Good heat insulation and separation of sheet metal part 1 and sheet metal part 2 2 are achieved through circular ceramic washers 3 and square ceramic washers 4, and then small boss 1 11 and small boss 2 22 are respectively cooperated with small blind hole 1 41 and small blind hole 2 42 for limiting, thereby reducing looseness caused by rotation and maintaining the stability of the shape of the heating element.

[0019] The part bracket of the present invention includes but is not limited to sheet metal part 1 and sheet metal part 2.

[0020] The sheet metal part 1 is L-shaped, and a small boss 11 is arranged on the inner side of the bend to cooperate with the square ceramic gasket 4 to play a limiting role.

[0021] The sheet metal part 2 is V-shaped, and a small boss 22 is provided on the outer side of the bend to cooperate with the square ceramic gasket 4 to play a limiting role.

[0022] The circular ceramic gasket 3 is in the shape of a stepped cylinder, and a circular hole is provided in the middle for accommodating a large flat head self-tapping screw 5 .
