Description

Technical Field

[0001] This utility model relates to the field of electric heating tube technology, and in particular to a quick-assembly and disassembly modular electric heating tube. Background Technology

[0002] An electric heating element is an electrical component that converts electrical energy into heat energy. By heating the heating wire, the heat is diffused into the metal tube, thereby transferring the heat to the object in contact with it. It is a relatively simple energy conversion, but a reasonable design of the heating element can improve the efficiency of energy conversion and minimize the loss in the conversion process.

[0003] A search revealed that Chinese Patent Publication No. CN212463534U discloses a combined electric heating tube, comprising a heating tube body and a fixing component. The heating tube body has a sealing component, and the bottom of the fixing component has a sealing groove into which the sealing component is inserted. An iron sheet is mounted on the sealing component, and a magnet is mounted on the fixing component within the sealing groove, attracting the iron sheet. A longitudinally positioned guide groove is provided on the fixing component, and a bidirectional threaded rod is longitudinally positioned within the guide groove and rotatably connected to the fixing component. An adjusting component is mounted on the bidirectional threaded rod and located around the fixing component. Moving components are located on both sides of the guide groove, and each moving component is threadedly connected to the bidirectional threaded rod. A connecting rod is vertically positioned at the bottom of the moving components, and a connecting component is horizontally positioned and connected to the connecting rod. A clamping component is mounted on the connecting component and clamps the heating tube body. This utility model facilitates the installation and disassembly of each heating tube, saving time and effort during the process, making replacement easy, and providing good heating performance, thus possessing practicality.

[0004] A search revealed that Chinese Patent Publication No. CN106162952A discloses a combined electric heating tube, which consists of two parts: a non-metallic tubular heater and a connector, connected by a sealing element. The outer shell of the tubular heater is a non-metallic blind-hole tube or a U-shaped tube, containing heating wire, magnesium oxide powder, or air. The connector is made of non-metallic or metallic materials. The sealing element has a flange and a hole with multiple teeth inside. The blind-hole tube or the U-shaped tube is installed in the hole. A clamping element presses the flange of the sealing element against the mounting surface of the connector using screws.

[0005] However, in the existing technology, the installation of electric heating tubes is relatively complicated, requiring the use of tools such as wrenches, which takes a long time and has poor practicality.

[0006] Therefore, we propose a quick-assembly and disassembly modular electric heating element to solve the above problems. Utility Model Content

[0007] The purpose of this invention is to address the shortcomings of existing technologies by proposing a quick-assembly and disassembly modular electric heating element.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0015] More preferably, the top end of the heating element passes through the connecting block and the top cover, and a charging interface is fixedly connected to the top end of the top cover, which passes through the top cover and is connected to the heating element.

[0016] More preferably, the bottom ends of the combined fixing block are provided with insertion holes, the insertion holes are cylindrical in shape, the insertion holes are located on both sides of the receiving groove, and the insertion holes are located below the limiting block.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0030] refer to Figure 1 The quick-assembly and disassembly modular heating element 4 includes a modular fixing block 1, which is used to fix components such as the connecting block 2 and the heating element 4. There is at least one modular fixing block 1. Multiple modular fixing blocks 1 can be connected after the heating element 4 is installed in the modular fixing block 1 according to the usage requirements. Multiple modular fixing blocks 1 connected as a whole can accommodate more heating elements 4.

[0031] refer to Figure 2 and Figure 3The connecting groove 6 is located on both sides inside the combined fixing block 1. The connecting groove 6 is used to accommodate components such as the connecting block 2. Limiting blocks 7 are fixedly connected to both ends of the connecting groove 6. The limiting blocks 7 are used to limit the locking block 11, thereby limiting the connecting block 2. The limiting block 7 is in the shape of a triangular truncated pyramid. Specifically, the large surface of the limiting block 7 faces upward and forms a slope, so that the locking block 11 will be squeezed and stored in the receiving chamber by the limiting block 7, so that the locking block 11 can pass through the limiting block 7.

[0032] refer to Figures 1-3 The connecting block 2 is located inside the connecting groove 6, which is a cuboid shape. The top of the connecting block 2 is also a cuboid shape that matches the shape of the connecting groove 6. The cuboid shape facilitates positioning and installation. The two ends of the connecting block 2 are connected to the limiting blocks 7. The middle part of the connecting groove 6 is an isosceles trapezoid shape, which is used to fit with the limiting blocks 7. The limiting blocks 7 can limit the connection block 2. The bottom of the connecting groove 6 is a cuboid block smaller than the top of the connecting groove, so that the limiting blocks 7 can pass through.

[0033] refer to Figures 1-3 The bottom of the connecting block 2 has embedded receiving grooves 10 on both sides. The receiving grooves 10 are used to receive the card block 11. The card block 11 is movably connected in the receiving groove 10. The top of the card block 11 is connected to the bottom of the limiting block 7. The card block 11 is made of plastic. Plastic material has good strength and can be deformed by external force.

[0034] refer to Figures 1-5 By setting the locking block 11, when multiple heating tubes 4 need to be combined and installed, the heating tubes 4 only need to be passed through the connecting groove 6. When the locking block 11 contacts the limiting block 7, it will retract into the receiving groove 10. After the locking block 11 passes the limiting block 7, the locking block 11 will unfold, and the top of the locking block 11 will be locked by the limiting block 7. Thus, the installation of the heating tubes 4 is relatively simple, and there is no need to use tools such as wrenches for installation. The installation does not take a long time and is highly practical.

[0035] refer to Figure 1 The front and back of the combined fixing block 1 are connected by fixing buckles 3. Multiple fixing buckles 3 are fixedly connected to multiple combined fixing blocks 1 by bolts. When more heating tubes 4 are needed, two adjacent combined fixing blocks 1 can be connected together by fixing buckles 3 and fixed by screwing in screws.

[0036] refer to Figure 5 The locking block 11 is centrally symmetrical about the connecting block 2, and the limiting block 7 is centrally symmetrical about the connecting block 2. This ensures good stability when the locking block 11 is locked at the bottom of the limiting block 7. The centrally symmetrical arrangement of the limiting block 7 facilitates the insertion of the connecting block 2. When the bottom of the connecting block 2 is inserted and tilted, the limiting block 7 helps to straighten the connecting block 2.

[0037] refer toFigure 1 The top of the connecting block 2 is fixedly connected to the top cover 5, which is used to connect the charging interface 12 and the heating tube 4. The bottom of the connecting block 2 is provided with the heating tube 4, which is provided with a heating wire for heating. The heating tube 4 and the connecting block 2 are perpendicular to each other, so that the heating range of adjacent heating tubes 4 is consistent, which can make the heating of the heating tube 4 more uniform.

[0038] refer to Figure 3 The top of the heating element 4 is connected to the connecting block 2 and the top cover 5. The top of the top cover 5 is fixedly connected to the charging interface 12. The charging interface 12 is connected to the heating element 4 through the top cover 5. The charging interface 12 can be connected to the mains power to charge the heating element 4, enabling the heating element 4 to achieve the heating function. At the same time, it can also be made more practical by connecting the mains power to only a single charging interface 12 to meet the heating needs.

[0039] refer to Figure 5 The bottom of the fixed block 1 is provided with insertion holes 14 at both ends. The insertion holes 14 are used to accommodate the insertion rod 13. The insertion holes 14 are cylindrical in shape, which makes it easier to insert the insertion rod 13. When the connection button 8 is pressed, the cylinder requires less force. The insertion holes 14 are located on both sides of the receiving groove 10 and below the limiting block 7, so that the insertion rod 13 can directly contact the card block 11 through the insertion holes 14.

[0040] refer to Figure 5 The insertion hole 14 is movably connected to the insertion rod 13. By pushing the insertion rod 13, a force can be applied to the locking block 11, which can be retracted into the receiving groove 10 due to the force of the insertion rod 13. Then the connecting block 2 can be pulled out directly to remove the heating tube 4. The insertion rod 13 is cylindrical in shape. A cylinder requires less force. The shape of the insertion rod 13 is consistent with the shape of the insertion hole 14, so the insertion rod 13 is not easy to shake in the insertion hole 14 and can concentrate the force.

[0041] refer to Figure 2 and Figure 5 One end of the insertion rod 13 is fixedly connected to a connection button 8, which is located on the outside of the combined fixing block 1. One end of the insertion rod is inserted into the insertion hole 14, and the other end is located on the outside of the combined fixing block 1. The user can push the insertion rod 13 into the combined fixing block 1 by pressing the connection button 8, and apply force to the locking block 11 by pressing the connection button 8 directly from the outside.

[0042] refer to Figure 2 The connecting button 8 is provided with a connecting rod 9 on the side facing the combination fixing block 1. The two ends of the connecting rod 9 are fixedly connected to the plug rod 13, so that the plug rod 13 in the two adjacent connecting slots 6 can be inserted synchronously by pressing the connecting rod 9, and two adjacent electric heating tubes 4 can be removed at the same time.
