Description

Technical Field

[0001] The utility model relates to the technical field of electric heating tubes, in particular to a double-layer electric heating tube for commercial microwave ovens. Background Art

[0002] A commercial microwave oven is a highly efficient heating device designed for commercial environments (such as restaurants, cafes, fast food restaurants, and hotels). Compared with household microwave ovens, commercial microwave ovens usually have larger capacity and stronger heating capacity, and can quickly heat and cook large amounts of food. The double-layer electric heating tube is an important heating component on commercial microwave ovens.

[0003] Currently, existing double-layer electric heating pipes are usually installed and fixed with screws, and the use of screw installation will require the use of tools during subsequent disassembly, which is cumbersome and reduces the disassembly efficiency of the double-layer electric heating pipe. Therefore, improvements are needed. Utility Model Content

[0004] The utility model aims to solve the problem in the prior art that tools are needed for subsequent disassembly, and proposes a double-layer electric heating tube for a commercial microwave oven.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: a double-layer electric heating tube for commercial microwave oven, comprising a carrying plate, a mounting plate and two connecting wires, a double-layer electric heating tube body being fixedly mounted on one side of the carrying plate, a connecting wire being fixedly mounted on the side of the carrying plate away from the double-layer electric heating tube body, a card slot being symmetrically provided on the outer wall of the carrying plate, a rectangular frame being fixedly mounted on the bottom of the mounting plate, a bidirectional screw being mounted inside the rectangular frame, a sliding plate being symmetrically threaded on the outer wall of the bidirectional screw, a clamping ring being fixedly mounted on the bottom end of the sliding plate, a card block being fixedly mounted on the inner wall of the clamping ring, and a rotating block being fixedly mounted on one end of the bidirectional screw.

[0006] Preferably, anti-slip grooves are evenly formed on the outer wall of the rotating block, and the clamping block is slidably connected to the clamping grooves.

[0007] Preferably, the sliding plate is slidably connected to the rectangular frame, and the bidirectional screw rod is rotationally connected to the rectangular frame.

[0008] Preferably, mounting holes are symmetrically formed through the surface of the mounting plate.

[0009] Preferably, insulating terminals are installed on the outer walls of the connecting wire 2 and the connecting wire 1, and screw holes are symmetrically opened on the tops of the insulating terminals, and insulating screws are connected to the inner threads of the screw holes.

[0010] Preferably, the insulating terminal is slidably connected to the second connecting line and the first connecting line.

[0011] Compared with the prior art, the advantages and positive effects of the present invention are:

[0012] 1. In the utility model, the rotating block is driven to drive the bidirectional screw rod to rotate inside the rectangular frame. During the rotation process, the bidirectional screw rod drives the two sets of sliding plates to slide in opposite directions inside the rectangular frame. During the sliding process, the two sets of sliding plates drive the two sets of clamping rings to move. During the movement process, the two sets of clamping rings drive the two sets of clamping blocks away from the two sets of clamping slots. After moving away, the bearing plate and the faulty double-layer electric heating tube body can be disassembled. This design makes it possible to disassemble the double-layer electric heating tube body by only rotating the rotating block, thereby effectively avoiding the need to use tools for subsequent disassembly of the double-layer electric heating tube body, thereby improving the maintenance efficiency of the double-layer electric heating tube body.

[0013] 2. In the utility model, the insulating terminal is slid along the connecting wire 1, and the connecting wire 2 is inserted into the insulating terminal after sliding a certain distance. After insertion, the insulating screws are screwed into the screw holes in sequence to fix the connecting wire 1 and the connecting wire 2. This design greatly improves the wiring efficiency between the connecting wire 1 and the connecting wire 2, and effectively avoids the need to use insulating tape for winding during the wiring process.

[0018] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0019] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] Example 1: Figure 1-Figure 3 As shown, the utility model provides a technical solution: a commercial microwave oven double-layer electric heating tube, comprising a carrying plate 1, a mounting plate 2 and a connecting line 3. A double-layer electric heating tube body 4 is fixedly mounted on one side of the carrying plate 1, and a connecting line 5 is fixedly mounted on the side of the carrying plate 1 away from the double-layer electric heating tube body 4. A card slot 6 is symmetrically provided on the outer wall of the carrying plate 1, a rectangular frame 7 is fixedly mounted on the bottom of the mounting plate 2, a bidirectional screw rod 8 is mounted inside the rectangular frame 7, a sliding plate 9 is symmetrically threaded on the outer wall of the bidirectional screw rod 8, a clamping ring 10 is fixedly mounted on the bottom end of the sliding plate 9, a clamping block 11 is fixedly mounted on the inner wall of the clamping ring 10, a rotating block 12 is fixedly mounted on one end of the bidirectional screw rod 8, and an anti-slip groove 13 is evenly provided on the outer wall of the rotating block 12, the clamping block 11 is slidingly connected to the card slot 6, the sliding plate 9 is slidingly connected to the rectangular frame 7, the bidirectional screw rod 8 is rotationally connected to the rectangular frame 7, and a mounting hole 14 is symmetrically provided on the surface of the mounting plate 2.

[0021] In this embodiment, by rotating the rotating block 12, the bidirectional screw 8 is driven to rotate inside the rectangular frame 7. During the rotation process, the bidirectional screw 8 will drive the two sets of sliding plates 9 to slide in opposite directions inside the rectangular frame 7. The two sets of sliding plates 9 will drive the two sets of clamping rings 10 to move during the sliding process. During the movement, the two sets of clamping rings 10 will drive the two sets of card blocks 11 away from the two sets of card slots 6. After moving away, the supporting plate 1 and the faulty double-layer electric heating tube body 4 can be disassembled. This design makes it possible to disassemble the double-layer electric heating tube body 4 by simply rotating the rotating block 12, thereby effectively avoiding the need to use tools for subsequent disassembly of the double-layer electric heating tube body 4, thereby improving the maintenance efficiency of the double-layer electric heating tube body 4.

[0022] Example 2: Figure 3 As shown, insulating terminals 15 are installed on the outer walls of connecting wire 2 3 and connecting wire 1 5. Screw holes 16 are symmetrically opened on the top of the insulating terminals 15. Insulating screws 17 are connected to the internal threads of the screw holes 16. The insulating terminals 15 are slidably connected to connecting wire 2 3 and connecting wire 1 5.

[0023] In this embodiment, the insulating terminal 15 is slid along the connecting wire 1 5, and after sliding a certain distance, the connecting wire 2 3 is inserted into the insulating terminal 15. After insertion, the insulating screws 17 are screwed into the screw holes 16 in sequence to fix the connecting wire 1 5 and the connecting wire 2 3. This design greatly improves the wiring efficiency between the connecting wire 1 5 and the connecting wire 2 3, and effectively avoids the need to use insulating tape for wrapping during the wiring process.

[0024] The working principle of this embodiment is as follows: when the double-layer electric heating tube body 4 fails and needs to be disassembled for maintenance, first rotate the rotary block 12, and the rotary block 12 drives the bidirectional screw rod 8 to rotate inside the rectangular frame 7. During the rotation process, the bidirectional screw rod 8 will drive the two sets of sliding plates 9 to slide in opposite directions inside the rectangular frame 7. The two sets of sliding plates 9 will drive the two sets of clamping rings 10 to move during the sliding process. During the movement, the two sets of clamping rings 10 will drive the two sets of card blocks 11 away from the two sets of card slots 6. After moving away, the bearing plate 1 and the faulty double-layer electric heating tube body 4 can be disassembled. This design makes it possible to disassemble the double-layer electric heating tube body 4 by only rotating the rotary block 12, thereby effectively avoiding the need to use tools for subsequent disassembly of the double-layer electric heating tube body 4, thereby improving the maintenance efficiency of the double-layer electric heating tube body 4. When wiring, first slide the insulating terminal 15 along the connecting wire 1 5, and then insert the connecting wire 2 3 into the insulating terminal 15 after sliding a certain distance. After insertion, screw the insulating screw 17 into the screw hole 16 in turn to fix the connecting wire 1 5 and the connecting wire 2 3. This design greatly improves the wiring efficiency between the connecting wire 1 5 and the connecting wire 2 3, and effectively avoids the need to use insulating tape for wrapping during the wiring process.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
