Description

Technical Field

[0001] The utility model relates to the technical field of electrothermal technology, and particularly relates to an installation structure of a flexible heating film. Background Technique

[0002] When the flexible heating film is applied to an electric heater, it can effectively reduce the volume in the thickness direction of the section of the heater, and has the advantages of large heating area, high heating efficiency, rapid temperature rise and uniform temperature, etc., which can bring a better heating experience.

[0003] During the working process of the flexible heating film, its working temperature can reach 300°C. Therefore, the relatively thin flexible heating film will have a thermal expansion phenomenon, resulting in problems such as wrinkling and heat accumulation. Therefore, the periphery of the flexible heating film needs to be fixed.

[0004] Existing fixing methods all use fixing strips with a fixed shape to assist in installation on the skeleton. In the installation structure, it is generally screw locking or snap fixing. The fixing strips will increase the additional weight of the equipment, and the overall installation cost will also increase accordingly, reducing the market competitiveness of the product; there are also those using glue bonding for installation. The construction process during gluing and installation is complex, the manual efficiency is low, and the replaceability and maintainability are poor; or directly use screws to install the heating film on the fixed frame. Due to the low strength of the heating film itself, at the state of stretching flat and repeatedly heating and cooling, the screw part will be torn, resulting in wrinkles in the heating film, and then affecting the local high temperature at the local wrinkled part when the heating film generates heat, seriously shortening the service life of the heating film, and even burning out the heating film. Summary of the Utility Model

[0005] The technical problem to be solved by the utility model is to provide an installation structure of a flexible heating film, which can effectively reduce the additional installation weight, control the installation cost, improve the installation quality of the heating film, and provide a structure that can not only be reliably installed but also has a certain elastic deformation space for the installation of the heating film, so that when the heating film expands and contracts due to heating and cooling, the heating film can have a certain amount of expansion and contraction, but still can effectively control the flatness of the heating film.

[0006] To solve the above technical problem, the utility model provides an installation structure of a flexible heating film, including a flexible support member and a plurality of support points. The flexible support member is cooperatively tightened through the plurality of support points to form a support frame with rigidity, and the side of the support frame is cooperatively connected with the corresponding side of the flexible heating film.

[0007] Furthermore, a plurality of connection through holes are arranged on the flexible heating film along the length direction of the side, and the flexible support member alternately passes through the plurality of connection through holes on the two surfaces of the flexible heating film in sequence.

[0008] Furthermore, the supporting point is a column pin, and holes are provided at the corners of the flexible heating film. The flexible heating film is sleeved on the column pin through the holes, and a hard supporting pad is provided on the holes.

[0009] Furthermore, an anti-slip head is provided on the pin.

[0010] Furthermore, a protective insulating layer is provided on the periphery of the upper and lower surfaces of the flexible heating film.

[0011] Furthermore, the connecting through hole is arranged inside a space formed by a plurality of supporting points.

[0012] Furthermore, a flexible support member is provided between two adjacent support points, and both ends of the flexible support member are connected to the support points or both ends of the flexible support member are connected to each other.

[0026] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present utility model and be able to implement it, but the specific embodiments cited are not intended to limit the present utility model.

[0027] Refer to Figures 1 to 4 As shown, the first embodiment of the installation structure of the flexible heating film of the present utility model includes a flexible support member 1 and at least three support points 5. Generally, the flexible heating film is rectangular, so four support points can be set. The support points are fixedly installed on the skeleton 111. The flexible support member forms a rigid support frame through the cooperation of multiple support points and is tightened. The support frame is arranged around the flexible heating film 2, and the side of the support frame is connected with the corresponding side of the flexible heating film. Through the rigid support frame formed by being tightened as the support, the four sides of the flexible heating film can be supported and fixed to the skeleton.

[0028] The flexible support member is preferably a soft rope. The diameter of the soft rope is 0.2 - 1 mm and is made of fiber material, or it can also be made of fiber + metal wire. The fiber can be a polymer material or an inorganic fiber material. While meeting the support requirements, the cost is low, and materials that can be bent such as metal wires can also be used. Taking the soft rope as an example, the soft rope can be wound around the four support points in a circle and the two ends are connected together to form a rigid support frame. At the connection position of the two ends of the soft rope, it can be connected and fixed into one body through a cable tie, a spring or a tightener 10. The cable tie has a low cost and is easy to operate; the spring has the ability to deform and stores energy through its own deformation, and can always maintain the rigidity of the soft rope after forming the support frame; the tightener can adjust the rigidity of the support frame at any time, is easy to operate, and even if the soft rope is loose, it can be operated to tighten, which is convenient for maintenance.

[0029] A plurality of connection through holes 4 are arranged on the side of the flexible heating film and along the side length. The flexible support member alternately passes through the plurality of connection through holes on the two surfaces of the flexible heating film. Refer to Figure 1 and Figure 4As shown, the preparation difficulty is effectively reduced. The connection through-holes can be obtained simply by drilling holes. The four sides of the flexible heating film are all passed through in the above manner. During the use and heat deformation process, the four sides are all restricted by the support frame formed by the soft ropes, that is, the movement is restricted in any direction on the plane, so as to achieve the purpose of four-side limitation. And the connection through-holes are arranged inside the space formed by surrounding multiple support points, which can better tighten the flexible heating film, especially increasing the stress intensity at the middle part of the side of the flexible heating film.

[0030] The above-mentioned support points can be dowel pins. The dowel pins can be conveniently locked on the skeleton through the threaded part. Sleeve holes 6 are arranged at the corners of the flexible heating film. The flexible heating film is sleeved on the dowel pins through the sleeve holes, playing a role in limiting and fixing the four corners of the flexible heating film. Cooperating with the connection and fixation of the soft ropes and the sides of the flexible heating film, a more effective support effect is formed. Since the stress at the corners of the flexible heating film is relatively large, in order to ensure that the flexible heating film will not be damaged due to concentrated stress at this place, a hard support pad 7 is arranged on the sleeve holes to improve the strength.

[0031] Since the dowel pin is a rod-shaped structure, there is a risk of slipping along its axial direction. Therefore, an anti-slip head 8 is arranged on the dowel pin to show that the soft rope and the flexible heating film will not fall off the dowel pin.

[0032] Protective insulating layers 9 can also be arranged on the peripheries of the upper and lower surfaces of the flexible heating film to improve the strength of the periphery of the flexible heating film and avoid damage problems during the support by the soft ropes.

[0033] In one embodiment, referring to Figure 5 As shown, compared with the first embodiment, sleeve holes are not arranged at the four corners of the flexible heating film, and its four corners are not connected to the support points. It can also effectively support and fix the flexible heating film. The support points can be selected as structures with hook parts, and the soft ropes will not slip off after being wound and tied.

[0034] In one embodiment, referring to Figure 6 As shown, compared with the first embodiment, the above-mentioned connection through-holes are replaced with connection points 3. The connection points can be glue, which fixes the soft ropes forming the support frame on the side of the flexible heating film. There is no need to drill holes or drill fewer holes on the flexible heating film, ensuring the side strength of the flexible heating film.

[0035] The connection points can also be protrusions located on one side of the flexible heating film. Through holes are arranged on the protrusions, and the soft ropes are arranged through the through holes. The connection points can be bonded to the flexible heating film or clamped and fixed.

[0036] In the above-mentioned multiple embodiments, for the connection between the flexible rope and the support points, in addition to using a single flexible rope to surround the four support points to form a support framework, it can also be formed by tying four flexible ropes. Specifically, a flexible rope is tied between two adjacent support points. The two ends of the flexible rope can be directly tied to the support points, or the flexible rope can be wound around two support points to form an annular setting effect, and then the two ends of the flexible rope are connected to each other. Here, they can be directly knotted and tied together, or auxiliary connections can be made through cable ties, springs or tighteners to ensure the stiffness after the flexible rope is fixed.

[0037] Referring to Figure 7 As shown, in the above-mentioned multiple embodiments for fixing the flexible heating film, an auxiliary support point 112 can also be selectively provided between two adjacent support points. The structure of the auxiliary support point can be the same as that of the support point. Its main function is to provide a limiting support point in the middle part of the side of the flexible heating film when the distance between two support points is relatively long, so as to improve the tension and the force-bearing effect is better, and the fixing effect of the flexible heating film is also improved accordingly.

[0038] In Figure 7 , auxiliary support points are provided on two vertical skeletons. Of course, a horizontal skeleton can also be provided between the two vertical skeletons, and then auxiliary support points are also provided on the horizontal skeleton, so that auxiliary support points are provided on all four sides of the flexible heating film. The number and position of the auxiliary support points can be set according to the connection requirements.

[0039] The above embodiments are only preferred embodiments given to fully illustrate the present invention, and the protection scope of the present invention is not limited thereto. Equivalent substitutions or transformations made by those skilled in the art on the basis of the present invention are all within the protection scope of the present invention.
