Description

Technical Field

[0001] This utility model relates to the field of electric heating plates, and in particular to a silicone rubber electric heating plate. Background Technology

[0002] Silicone rubber electric heating plates are widely used heating elements, their origins traceable to the continuous development and improvement of heating technology. With the advancement of industry and technology, the demand for heating technology has been increasing. Traditional heating methods (such as flame heating and gas heating) suffer from problems such as inaccurate temperature control, high energy consumption, and poor safety. To address these issues, silicone rubber electric heating plates were developed. Silicone rubber possesses excellent high-temperature resistance, insulation, flexibility, and plasticity, allowing it to be flexibly adapted to heating areas of different shapes, making it an important heating element in industrial, medical, and laboratory fields.

[0003] Traditional silicone rubber electric heating plates lack a top-end mounting device, requiring screws, adhesives, or welding to fix them to the surface of the object being heated. This increases labor time and cost. Typical silicone rubber electric heating plates need to be installed on the object using screws or other fixing devices to ensure close contact between the heating plate and the object. Additional tools are required for quick installation. The lack of a quick-installation and adjustable fixing structure leads to low installation efficiency and difficulty in fixing the plate. Furthermore, it is difficult to adapt to workpieces of different shapes or sizes. Therefore, a new silicone rubber electric heating plate is proposed to solve these problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 , Figure 2An embodiment of this utility model is provided: a silicone rubber electric heating plate, including a fixed frame 1 and a silicone rubber electric heating plate body 2. The fixed frame 1 has a rectangular structure and its top and bottom surfaces are open. The silicone rubber electric heating plate body 2 is embedded in the fixed frame 1 and fits tightly with it. The inner wall of the fixed frame 1 is provided with a positioning component 11, and the top of the fixed frame 1 is provided with a pressing component 10.

[0032] Reference Figure 3 , Figure 4 The clamping assembly 10 includes an arc-shaped pressure bar 101 and two symmetrically arranged hinge shafts 102. An adjusting block 103 is fixedly connected to the top of the arc-shaped pressure bar 101. The arc-shaped pressure bar 101 is made of elastic metal material. When the arc-shaped pressure bar 101 is not subjected to external force, it is in a naturally extended arc state. A threaded post 104 is fixedly connected to the top of the adjusting block 103. The threaded post 104 is slidably connected to the inner wall of the fixed frame 1. The sliding direction of the threaded post 104 is up and down and it cannot rotate. A locking nut 105 is sleeved on the outside of the threaded post 104. The locking nut 105 is rotatably connected to the top of the fixed frame 1.

[0033] Reference Figures 2-4 The fixed frame 1 has a support net 106 inside. The support net 106 is located below and parallel to the main body 2 of the silicone rubber electric heating plate. The four edges of the support net 106 are fixedly connected to the inner wall of the fixed frame 1. Several support columns 107 are fixedly connected to the top of the support net 106. The top of the support column 107 is provided with a disc-shaped pressure head 108 integrated with it. The top of the pressure head 108 is tightly attached to the bottom surface of the main body 2 of the silicone rubber electric heating plate. The diameter of the pressure head 108 is larger than the diameter of the support column 107. The top surface of the pressure head 108 is provided with an elastic pad integrated with it. The elastic pad is made of polyurethane.

[0034] Reference Figures 3-5 The positioning component 11 includes four rectangularly distributed positioning claws 111. The positioning claws 111 are rotatably connected to the bottom surface of the fixed frame 1 via a rotating shaft 112. The rotating shaft 112 passes through the middle of the positioning claws 111 and is rotatably connected to the fixed frame 1 via a bearing. The front and rear sides of the positioning claws 111 are provided with barbs 113 integrated therewith. The top of the barbs 113 is provided with a toothed groove 114. The bottom of the positioning claws 111 is provided with a protrusion 115 integrated therewith. The top of the positioning claws 111 contacts the bottom of the silicone rubber electric heating plate body 2.

[0035] Reference Figures 1-3 A sealing ring 17 is fixedly connected to the inner wall of the rear side of the fixed frame 1. A wire hole 18 is provided inside the sealing ring 17. The wire hole 18 is in contact with the outer wall of the power cord 19 of the silicone rubber electric heating plate body 2. The sealing ring 17 seals and protects the power cord 19 of the silicone rubber electric heating plate body 2 to prevent external dust or liquid from entering the interior of the fixed frame 1.

[0036] Reference Figures 2-4 Each of the four corners of the top of the fixed frame 1 is provided with a guide post 21. The bottom of the guide post 21 is fixedly connected to a limit block 20. The bottom of the limit block 20 contacts the top of the silicone rubber electric heating plate body 2. The guide post 21 is slidably connected to the inner wall of the fixed frame 1. A compression spring 22 is sleeved on the outer wall of the guide post 21. The bottom of the compression spring 22 contacts the top of the limit block 20. The guide post 21 and the compression spring 22 provide a downward elastic force. The top of the compression spring 22 contacts the bottom of the fixed frame 1.

[0037] Working principle: In use, after the silicone rubber electric heating plate body 2 is embedded into the fixed frame 1, the hinge shafts 102 at both ends of the arc-shaped pressure strip 101 press down on the silicone rubber electric heating plate body 2. By rotating the locking nut 105, the threaded column 104 slides downward in a straight line, driving the adjusting block 103 to move downward and press the arc-shaped pressure strip 101, thereby causing the arc-shaped pressure strip 101 to undergo elastic deformation. After the locking nut 105 is tightened, the position of the arc-shaped pressure strip 101 is fixed, thus achieving the initial fixation of the silicone rubber electric heating plate body 2.

[0038] By rotating the positioning claw 111, its barb 113 hooks onto the silicone rubber electric heating plate body 2. During the rotation of the positioning claw 111 around the rotating shaft 112, the protrusion 115 approaches the inner wall of the fixed frame 1, magnetically limiting the rotation angle of the positioning claw 111. The tooth groove 114 of the barb 113 increases the friction between the silicone rubber electric heating plate body 2 and the silicone rubber electric heating plate body 2, preventing displacement when the silicone rubber electric heating plate body 2 is fixed inside the fixed frame 1.

[0039] The support net 106 and support column 107 provide uniform support for the silicone rubber electric heating plate body 2, preventing it from deforming during use, while ensuring the uniformity of heat transfer and extending the service life of the silicone rubber electric heating plate 2; the wire hole 18 in the sealing ring 17 seals and protects the power cord 19 of the silicone rubber electric heating plate body 2, preventing external dust or liquid from entering the fixed frame 1.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
