Description

Anti-bending PTC heater

Technical Field

The utility model belongs to the technical field of the PTC heater, concretely relates to prevent crooked PTC heater.

Background

PTC heater heating core among the prior art is fixed the supporting seat and panel beating in heating core both sides through the screw, and such fixed establishment does not reserve the space that the heating core expands the diffusion to both sides, and the heating core heating expansion is yielding, leads to heating core both sides to be strutted, and is inside including the supporting seat simultaneously, and fixed knot such as panel beating also can suffer destruction to cause the heater to damage, reduce the life of heater, also can lead to heating core to leak simultaneously, bring the potential safety hazard.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome among the prior art defect that PTC heater heating core inflation diffusion headspace is not enough, provide a prevent crooked PTC heater, including the heating core, still include the slip fixed knot structure, on the slip fixed knot structure was located to the heating core, the slip fixed knot structure includes a plurality of supporting seat and an at least panel beating slide rail, a plurality of supporting seat and panel beating slide rail sliding connection, on a plurality of supporting seat was located to the heating core.

Further, the quantity of supporting seat is 3, and 3 supporting seats equidistance locate the below of heating core.

Further, the quantity of panel beating slide rail is two, and two both ends of supporting seat are located respectively to two panel beating slide rails.

Further, the length of sheet metal slide rail is longer than the length of heating core.

Further, the bottom of supporting seat is equipped with a plurality of pulleys, and the supporting seat passes through pulley and panel beating slide rail sliding connection.

Furthermore, the two ends of the metal plate sliding rail are provided with limiting blocks.

Further, still include the support, the heating core passes through the support and locates the supporting seat.

Further, the bottom of supporting seat is equipped with a plurality of sliders, and the supporting seat passes through slider and panel beating slide rail sliding connection.

The utility model discloses the beneficial effect who possesses:

1. through with supporting seat and panel beating slide rail sliding connection, on the supporting seat was located to the heating core, when the expansion of heating core was diffused, the supporting seat slided on the panel beating slide rail along with the diffusion of heating core, has avoided the supporting seat to be propped the bending by the heating core.

2. The length of the metal plate slide rail is longer than that of the heating core body, and a space is reserved for the expansion and diffusion of the heating core body to two sides.

3. Through set up the pulley in supporting seat bottom for the supporting seat can slide better.

Detailed Description

The present invention will be further described with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

As shown in fig. 1-2, the utility model discloses a prevent crooked PTC heater, including heating core 1, still include the slip fixed knot structure, on the slip fixed knot structure was located to heating core 1, the slip fixed knot structure included a plurality of supporting seat 2 and an at least panel beating slide rail 3, a plurality of supporting

seat

2 and 3 sliding connection of panel beating slide rail, heating core 1 was located on a plurality of supporting seat 2.

From the angle of saving cost and stress balance, preferably set up 3 supporting

seats

2,3 supporting seats 2 equidistance respectively locate the below of heating core 1, form fixed stay to heating core 1. The quantity of panel beating slide rail 3 is two, and two both ends of supporting seat 2 are located respectively to two panel beating slide rails 3.

In order to reserve a sufficient expansion diffusion space for the heating core body 1, the length of the sheet metal slide rail 3 is longer than that of the heating core body 1, the arrangement direction of the sheet metal slide rail 3 is consistent with that of the heating core body 1, preferably, the sheet metal slide rail 3 is 5-10 cm longer than the heating core body 1, and a fixed cavity of the heater is enlarged accordingly.

In order to make the supporting seat 2 slide better, the bottom of the supporting seat 2 is provided with a plurality of pulleys 4, and the supporting seat 2 is connected with the metal plate sliding rail 3 in a sliding manner through the pulleys 4. Except pulley sliding connection, the supporting seat 2 still can adopt slider sliding connection, and the bottom of supporting seat 2 is equipped with a plurality of sliders, and supporting seat 2 passes through slider and 3 sliding connection of panel beating slide rail. Meanwhile, in order to avoid the back-and-forth sliding of the heating core body 1 on the metal plate sliding rail 3, the two ends of the heating core body 1 are respectively provided with an elastic structure and a heater cavity inner wall in a butting mode, the elastic structure plays a limiting role in the heating core body 1, and meanwhile, the elastic structure can be extruded when the heating core body 1 expands and diffuses, and the inner wall of a heater cavity cannot be extruded.

The both ends of panel beating slide rail 3 are equipped with stopper 5, avoid supporting seat 2 landing.

Because the heating core 1 is easy to expand and spread, the fixing area of the heating core 1 and the supporting seat 2 needs to be as small as possible, preferably, the heating core 1 is fixed by the support 6, the support 6 is a Y-shaped support, the heating core 1 is fixed at the upper end of the Y-shaped support from two sides of the heating core 1 through screws, and the bottom end of the support 6 is fixed on the supporting seat 2. Such fixing does not affect expansion and diffusion of the heating core 1.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be considered as the protection scope of the present invention.
