Description

Technical Field

[0001] This utility model belongs to the field of electric heating tube fixing technology, specifically relating to an electric heating tube fixing structure for an electric heater. Background Technology

[0002] Electric heating is the process of converting electrical energy into heat energy. It is used to heat, maintain, and heat flowing liquid and gaseous media. When the heating medium passes through the heating chamber of the electric heater under pressure, the huge amount of heat generated by the electric heating element is uniformly carried away by the principle of fluid thermodynamics, so that the temperature of the heated medium reaches the user's process requirements.

[0003] While existing technologies use electric heating tubes to heat flowing liquid and gaseous media, they cannot accurately position and install containers of different sizes. This results in installation deviations between the container and the mounting components, reducing the stability of the electric heating tube installation and making it prone to shaking. Therefore, those skilled in the art have provided an electric heating tube fixing structure for an electric heater to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this utility model is to provide a simple and reasonably designed electric heater heating tube fixing structure in order to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] An electric heating tube fixing structure for an electric heater includes a fixing plate. The front and rear ends of the inner wall of the fixing plate are respectively provided with sliding grooves. A connector is provided at the top of the fixing plate, and an electric heating tube is fixedly connected to the bottom end of the connector. A clamping device is provided at the top of the fixing plate, and a support device is provided at the rear side of the bottom end of the fixing plate. Through holes are respectively provided at the front and rear ends of the fixing plate, and an installation mechanism is provided on the inner wall of the two through holes.

[0007] As a further optimization of this utility model, the installation mechanism includes second slide rods that are slidably connected to both sides of the inner walls of the two through holes, and support plates that are fixedly connected to the other ends of the four second slide rods are respectively provided on both sides of the fixing plate, and second springs are respectively provided on the inner walls of the two through holes.

[0008] As a further optimization of this utility model, the clamping device includes two mounting brackets fixedly connected to the top of the fixed plate. One of the mounting brackets has a limit rod fixedly connected to its inner wall, and the other mounting bracket has a bidirectional screw rod rotatably connected to its inner wall. One end of the bidirectional screw rod is fixedly connected to a first knob, and two sliding plates that are slidably connected to the side walls of the limit rod are threaded on both sides of the bidirectional screw rod. The side walls of the two sliding plates are respectively provided with limit mechanisms.

[0009] As a further optimization of this utility model, the limiting mechanism includes a first slide rod that is slidably connected to the side wall of the slide plate, a clamping block fixedly connected to one end of each of the two first slide rods, a first spring sleeved on the side wall of each of the two first slide rods, and a stabilizing mechanism provided on the side wall of the clamping block.

[0010] As a further optimization of this utility model, the stabilizing mechanism includes first sliders that are fixedly connected to both sides of the clamping block, and the two first sliders are slidably connected to the inner walls of the two grooves respectively, and a limit plate is fixedly connected to the bottom end of the clamping block.

[0011] As a further optimization of this utility model, the support device includes a fixed frame fixedly connected to the bottom end of the fixed plate, an adjusting screw is rotatably connected to the inner wall of the fixed frame, a second slider is threadedly sleeved on the side wall of the adjusting screw, a limit frame is fixedly connected to the front end of the second slider, and a second knob is fixedly connected to the bottom end of the adjusting screw.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. In this utility model, by setting a support device, the heating element is inserted into the limiting frame. The second knob is rotated to drive the adjusting screw to rotate, thereby adjusting the position of the heating element. This makes it convenient to fix the heating element according to the actual length of the heating element, so that it can be connected with the connector and avoid the heating element from shaking during use.

[0014] 2. In this utility model, by setting up a clamping device, rotating the first knob drives the bidirectional lead screw to rotate, adjusting the position of the slide plate, so that the clamping block can clamp the side wall of the connector. The clamping block slides on the slide plate through the first slide rod, and under the elastic force of the first spring, it can effectively ensure that the connector will not be damaged when the clamping block is fixed to the side wall of the connector, effectively improving the stability during fixation.

[0021] The present application will now be described in further detail with reference to the accompanying drawings.

Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0022] Example 1

[0023] like Figure 1 , Figure 2 As shown, an electric heater heating element fixing structure includes a fixing plate 3. The front and rear ends of the inner wall of the fixing plate 3 are respectively provided with sliding grooves 8. A connector 6 is provided at the top of the fixing plate 3. An electric heating element 7 is fixedly connected to the bottom end of the connector 6. A clamping device 1 is provided at the top of the fixing plate 3. The clamping device 1 can be used to install and fix the connector 6 and ensure that the connector 6 will not be damaged during fixing. A support device 2 is provided at the rear side of the bottom end of the fixing plate 3. The support device 2 can be used to fix electric heating elements 7 of different specifications and ensure the stability during installation. Through holes 9 are respectively provided at the front and rear ends of the fixing plate 3.

[0024] like Figure 1 , Figure 2 and Figure 4 As shown, the two through holes 9 are slidably connected to the two sides of the inner wall of the second sliding rods 4 respectively. The two sides of the fixing plate 3 are respectively provided with support plates 5 which are fixedly connected to the other ends of the four second sliding rods 4. The inner walls of the two through holes 9 are respectively provided with second springs 10. After installation, by pressing the support plate 5, the second sliding rods 4 on both sides of the fixing plate 3 are respectively stored into the through holes 9. After the device is moved to the designated position in the container, the restriction on the support plate 5 is released. Under the elastic force of the second spring 10, the support plate 5 can be made to fit against the inner wall of the container, thereby fixing the position of the device.

[0025] like Figure 5As shown, a fixing frame 201 is fixedly connected to the bottom end of the fixing plate 3. An adjusting screw 205 is rotatably connected to the inner wall of the fixing frame 201. A second slider 202 is threaded onto the side wall of the adjusting screw 205. A limit frame 204 is fixedly connected to the front end of the second slider 202. A second knob 203 is fixedly connected to the bottom end of the adjusting screw 205. The heating element 7 is inserted into the limit frame 204. The second knob 203 is rotated to drive the adjusting screw 205 to rotate, thereby adjusting the position of the heating element 7. This allows the heating element 7 to be fixed according to its actual length, so that it can be connected to the connector 6, preventing the heating element from shaking during use.

[0026] like Figure 3 , Figure 4 As shown, two mounting brackets 104 are fixedly connected to the top of the fixing plate 3. One mounting bracket 104 has a limit rod 110 fixedly connected to its inner wall, and the other mounting bracket 104 has a bidirectional lead screw 105 rotatably connected to its inner wall. One end of the bidirectional lead screw 105 is fixedly connected to a first knob 109. The two sides of the bidirectional lead screw 105 are respectively threaded with sliding plates 107 that are slidably connected to the side wall of the limit rod 110. Rotating the first knob 109 causes the bidirectional lead screw 105 to rotate, adjusting the position of the sliding plates 107 so that the clamping block 102 can clamp the side wall of the connector 6.

[0027] like Figure 3 , Figure 4 As shown, the slide plate 107 has a first slide rod 108 slidably connected to its side wall. One end of each of the two first slide rods 108 is fixedly connected to a clamping block 102. The side walls of the two first slide rods 108 are respectively fitted with first springs 103. The clamping blocks 102 are respectively fixedly connected to the two sides of their respective sides, and the two first sliders 101 are slidably connected to the inner walls of the two slide grooves 8. The bottom end of the clamping block 102 is fixedly connected to a limit plate 106. The clamping block 102 slides on the slide plate 107 via the first slide rods 108. Under the elastic force of the first springs 103, it can effectively ensure that the clamping block 102 will not damage the connector 6 when it is fixed to the side wall of the connector 6, thus effectively improving the stability during fixation.

[0028] It should be noted that in the use of this type of electric heater's heating element fixing structure, the heating element 7 is inserted into the limiting bracket 204. Rotating the second knob 203 drives the adjusting screw 205 to rotate, thereby adjusting the position of the heating element 7. This allows for fixing the heating element 7 according to its actual length, enabling it to mate with the connector 6. Rotating the first knob 109 drives the bidirectional screw 105 to rotate, adjusting the position of the sliding plate 107, allowing the clamping block 102 to clamp the side wall of the connector 6. The clamping block 102 is located via the first sliding rod 108. The plate 107 slides on the plate, and under the elastic force of the first spring 103, it can effectively ensure that the connector 6 will not be damaged when the clamping block 102 is fixed to the side wall of the connector 6, thus effectively improving the stability during fixation. After installation, by pressing the support plate 5, the second sliding rods 4 on both sides of the fixing plate 3 are respectively stored into the through hole 9. After the device is moved to the designated position in the container, the restriction on the support plate 5 is released. Under the elastic force of the second spring 10, the support plate 5 can be made to fit against the inner wall of the container, thus fixing the position of the device.

[0029] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
