Description

Technical Field

[0001] This utility model relates to the field of heating belts, specifically to a tensile silicone heating belt. Background Technology

[0002] Among existing heating belt products, silicone heating belts are widely used in various heating applications such as pipe insulation, medical equipment, and outdoor instrument antifreeze due to their excellent flexibility, insulation, and chemical corrosion resistance. However, the tensile strength of traditional silicone heating belts mainly relies on the strength provided by the silicone material itself, and most silicone sheets adopt a simple planar structure. Although this allows for quick cutting, the tensile strength is not ideal. When excessive tension causes cracks, they can easily propagate rapidly along the silicone matrix, increasing the probability of damage to the silicone heating belt and raising maintenance costs and replacement frequency. Utility Model Content

[0003] The purpose of this utility model is to provide a tensile silicone heating strip with good tensile properties. It is easy to assemble and mold, and compared with the traditional silicone substrate with a planar structure, it can also appropriately reduce the extent of crack extension along the middle of the silicone substrate and the degree of damage to the silicone heating strip. It is convenient for observation, judgment and subsequent maintenance, with appropriate maintenance costs and replacement frequency, and improves the positional stability and performance of this tensile silicone heating strip on the corresponding heating part of the part to be heated.

[0004] The technical solution adopted by this utility model to solve the above problems is: A tensile silicone heating strip includes a first silicone substrate and a second silicone substrate. The first silicone substrate has multiple sets of connecting strips arranged at intervals around its periphery to form connecting portions. The second silicone substrate is located between the connecting portions and is adhered to the first silicone substrate.

[0005] Preferably, multiple sets of connectors are arranged at intervals along the end face of the long side of the first silicone substrate, and each connector is provided with an adhesive part. Multiple sets of second connectors with through holes are installed along the end face of the short side of the first silicone substrate and at positions corresponding to the connectors.

[0006] Preferably, the adhesive part of the connector is also provided with a connection hole.

[0007] Preferably, a second connection portion is formed by multiple sets of arc-shaped end faces connected to the corresponding end face of the first silicone substrate between adjacent connectors.

[0008] Preferably, a glass fiber cloth is also adhered to the first silicone substrate away from the second silicone substrate.

[0009] Compared with the prior art, this utility model has the following advantages and effects: This utility model is a tensile-resistant silicone heating strip. Compared with traditional silicone heating strips that are all cut and formed using a planar structure, this one-piece molding process, in which multiple sets of spaced connecting strips are arranged in a single piece on a first silicone substrate, further improves the structural strength of the first silicone substrate. Combined with the connection process of fasteners and other connectors that primarily function on the first silicone substrate, which can be added and tightened correspondingly to the position of the connecting part, this effectively improves the tensile strength of the silicone heating strip. Furthermore, the number of connecting strips in the connecting part can be set and arranged according to the specifications and cutting shape of the second silicone substrate. This allows the installation frame formed on the first silicone substrate to further improve the ease and efficiency of adjusting the position during the pasting process of the second silicone substrate, thus improving the assembly efficiency of this tensile-resistant silicone heating strip. Simultaneously, the structure and arrangement of multiple sets of spaced connecting strips in the connecting part can also appropriately reduce the probability of cracking at the edge of the first silicone substrate. When cracks do occur at the edge, they first extend along the multiple sets of spaced connecting strips, and when cracks appear on the corresponding side edge... The cracking process only begins on the corresponding side of the second silicone substrate after all the connecting strips have cracked. Compared to the traditional silicone substrate with a planar structure, this can appropriately reduce the extent of crack extension along the center of the silicone substrate and the degree of damage to this type of silicone heating strip. This facilitates observation, judgment, and subsequent maintenance, and reduces maintenance costs and replacement frequency. In addition, the height of the protruding end face of the connecting strip on the corresponding end face of the first silicone substrate is not higher than the thickness of the second silicone substrate. Therefore, when this type of tensile silicone heating strip is installed around the outer periphery of the part to be heated so that the second silicone substrate is in contact with its outer wall, it can ensure the adhesion between the second silicone substrate and the corresponding outer wall of the part to be heated and the corresponding heating effect. At the same time, when this type of tensile silicone heating strip is tightly installed on the part to be heated, the structure of multiple sets of spaced connecting strips in the connecting part can be combined with the deformation process of the second silicone substrate and the outer wall of the part to be heated to synchronously adhere and resist. Under the corresponding force, it can have a certain anti-slip effect, which can further improve the positional stability and performance of this type of tensile silicone heating strip on the corresponding heating part of the part to be heated.

Detailed Implementation

[0014] The present invention will now be described in detail with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0015] See Figure 1-4 This embodiment relates to a tensile silicone heating band, including a first silicone substrate 1 and a second silicone substrate 2. The periphery of the first silicone substrate 1 is provided with a plurality of sets of connecting strips 101 arranged at intervals to form a connecting part 10. The second silicone substrate 2 is located between the connecting parts 10 and is adhered to the first silicone substrate 1.

[0016] Specifically in this embodiment, such as Figure 1 The overall structural design of this type of tensile silicone heating belt, combined with... Figure 2-4 As shown, the second silicone substrate 2 can be cut and shaped using a traditional planar structure, and heating wires can be wound and arranged around the corresponding area in conjunction with the layout area 20 set thereon. The first silicone substrate 1 can be integrally cut and shaped with a connecting part 10 formed by multiple sets of spaced connecting strips 101. Specifically, the connecting strips 101 in the connecting part 10 can be set according to the overall structure of this tensile silicone heating band according to the usage requirements. Figure 2 For example, the process of cutting and laying out multiple sets of intervals along its long side, or using... Figure 3For example, multiple sets of cut and trimmed connecting strips 101, arranged in a frame shape, are arranged around the perimeter of the corresponding wall surface of the first silicone substrate 1. This allows for the integral bonding process of the second silicone substrate 2 with the area formed by the connecting portion 10 on the corresponding side of the first silicone substrate 1 through hot pressing. Simultaneously, the heating wires arranged in the arrangement area 20 on the second silicone substrate 2 during the early bonding stage can be pre-connected to the connecting lines 11 at the corresponding positions on the first silicone substrate 1, thus completing the overall connection and forming process of this tensile silicone heating band. In actual use, it can be arranged around the perimeter of the required heating component. Furthermore, depending on the usage requirements, this tensile silicone heating band can be constructed by separately attaching the first silicone substrate 1 and the connecting portion 10 on the corresponding side of the first silicone substrate 1. The two silicone substrates 2 are fixed by adhesive structures at both ends of the corresponding wall surface, or by fastening with snap fasteners or other connectors attached to the corresponding wall surfaces of the first silicone substrate 1 and the second silicone substrate 2 using fiberglass cloth 7. This, combined with the connection of the connecting wire 11 to temperature control elements such as thermostats and power cords commonly found on silicone heating strips, enables the heating and temperature adjustment of this tensile silicone heating strip. Compared to traditional silicone heating strips that are cut and formed from planar structures, the connecting part 10, formed by multiple sets of spaced connecting strips 101, is integrally formed on the first silicone substrate 1 after cutting, which further improves... The structural strength of the first silicone substrate 1, combined with the connection process where the connectors such as snap fasteners on the first silicone substrate 1 can be added and tightened correspondingly to the position of the connecting part 10, can effectively improve the tensile strength of this type of silicone heating band. Furthermore, the corresponding number of connecting strips 101 in the connecting part 10 can be set and arranged according to the specifications and corresponding cutting shape of the second silicone substrate 2, so that the mounting frame formed on the first silicone substrate 1 can further improve the ease and efficiency of adjusting the corresponding position during the pasting process of the second silicone substrate 2, thus improving the assembly efficiency of this tensile silicone heating band. At the same time, the structural design and arrangement of multiple sets of spaced connecting strips 101 in the connecting part 10 can also appropriately... This design reduces the probability of cracking at the edge of the first silicone substrate 1. When cracks do appear at the edge, they first extend sequentially along multiple sets of spaced connecting strips 101. Only after all sets of connecting strips 101 on the corresponding edge have cracked does the cracking process begin on the corresponding side of the second silicone substrate 2. Compared to traditional silicone substrates with a planar structure, this design also appropriately reduces the extent of crack extension along the center of the silicone substrate and the degree of damage to the silicone heating band. This facilitates observation, assessment, and subsequent maintenance, reducing maintenance costs and replacement frequency. Furthermore, the height of the protruding end face of the connecting strip 101 on the corresponding end face of the first silicone substrate 1 is not higher than the thickness of the second silicone substrate 2.Therefore, when this type of tensile silicone heating strip is installed and heated by wrapping around the periphery of the part to be heated so that the second silicone substrate 2 adheres to its outer wall, it can ensure the adhesion between the second silicone substrate 2 and the corresponding outer wall of the part to be heated and the corresponding heating effect. Simultaneously, when this type of tensile silicone heating strip is tightly installed on the part to be heated, the structure of the multiple sets of spaced connecting strips 101 in the connecting part 10 can synchronously adhere and abut against the outer wall of the part to be heated during the deformation process of the second silicone substrate 2. Under corresponding force, it can have a certain anti-slip effect, further improving the positional stability and performance of this type of tensile silicone heating strip on the corresponding heating part of the part to be heated.

[0017] Multiple sets of connectors 3 are arranged at intervals along the long side of the first silicone substrate 1, and each connector 3 is provided with an adhesive part 31. Multiple sets of second connectors 4 with through holes 40 are installed along the short side of the first silicone substrate 1 at positions corresponding to the connectors 10. When this tensile silicone heating tape is installed around the periphery of the part to be heated, the second connectors 4 can be adhered to the corresponding wall surface of the first silicone substrate 1 by means of fiberglass cloth 7. Combined with the through holes 40, a tension spring or other connecting component can be inserted through the through holes 40 to connect the two ends, thus achieving a tight fit of this tensile silicone heating tape around the periphery of the heating part of the part to be heated. During the process, multiple sets of connectors 3 can be bonded and fixed to the corresponding positions on the outer wall of the component to be heated by the adhesive parts 31 provided thereon. This can further improve the stability of this tensile silicone heating band at the corresponding installation position of the component to be heated. At the same time, the bonding process of multiple sets of connectors 3 to the corresponding outer wall of the component to be heated can also disperse a certain amount of tensile stress, and appropriately reduce the probability of damage to this silicone heating band caused by stress concentration in the short side direction. When there is no need for use, the corresponding release paper can be attached to the adhesive parts 31 of the connectors 3 to avoid unnecessary contamination of the adhesive parts 31 and ensure the bonding stability of the adhesive parts 31 on the connectors 3.

[0018] The adhesive part 31 of the connector 3 is also provided with a connection hole 32. Specifically, when using this type of tensile silicone heating tape, it can be connected by passing it through or hanging it according to the installation requirements and the connection hole 32 provided on the connector 3. The adhesive process of its adhesive part 31 can further improve the structural flexibility and fixing effect of the connector 3, and meet different installation requirements.

[0019] The adjacent connectors 3 are connected to the corresponding end face of the first silicone substrate 1 by multiple sets of arc-shaped end faces 5 forming second connecting parts 6. Specifically, the multiple sets of arc-shaped end faces 5 and the second connecting parts 6 formed by the connectors 3 can be combined with the structure of multiple sets of connecting strips 101 in the connecting part 10 and act on the first silicone substrate 1 for integral cutting and molding. This can further improve the tensile strength of this silicone heating band, facilitate connection and fixation while reducing the risk of edge cracking and improving the structural stability of this tensile silicone heating band.

[0020] A fiberglass cloth 7 is also adhered to the first silicone substrate 1, which is located away from the second silicone substrate 2. Specifically, the fiberglass cloth 7 can be added to the corresponding wall surface of the first silicone substrate 1 according to the usage requirements. The cut shape of the corresponding fiberglass cloth 7 is as follows: Figure 1 and Figure 3 The planar structure can be set as an example. At this time, the snap fastener or the second connector 4 can be combined with multiple sets of glass fiber cloth 7 and pasted on the glass fiber cloth 7 pasted on the first silicone base 1. The addition of glass fiber cloth 7 can further improve the structural strength of the first silicone base 1 and improve the stability of this tensile silicone heating band. In addition, the glass fiber cloth 7 can also be pasted on the corresponding wall surface of the second silicone base 2 away from the first silicone base 1 according to the usage requirements. This can further improve the structural strength of the second silicone base 2 without affecting the heating effect. When it is pasted on the corresponding outer wall of the part to be heated, it can also play a certain protective and anti-slip role, meeting different usage requirements.

Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not depart from the content of this specification or exceed the scope defined in the claims, all of which shall fall within the protection scope of this invention.
