[0002] With the development of automation and intelligent technologies, especially in manufacturing, chemical industry and food processing, higher requirements are placed on the efficiency, safety and flexibility of heating equipment. When heating, drying and curing materials, electric heaters with support frame structures are needed to ensure precise control and efficient operation of the process.

[0003] However, electric heaters still have many shortcomings in actual use. For example, the support structure design of traditional electric heaters is relatively simple, and the heating tube is prone to displacement due to vibration or external force during the heating process, which affects the heating effect and equipment life. At the same time, traditional equipment is time-consuming and labor-intensive to install and disassemble, which reduces maintenance efficiency and increases operating costs. Therefore, it is necessary to design an electric heater with a support frame structure. Utility Model Content

[0005] This utility model is achieved using the following technical solution: an electric heater with a support frame structure, comprising a heating tube, a resistance wire fixedly mounted on the outer surface of the heating tube, and a connecting tube fixedly mounted at the front end of the heating tube, and further comprising:

[0006] The main mounting assembly includes a first support frame, and a first limiting groove is provided inside the first support frame.

[0007] An auxiliary installation component, the auxiliary installation component including a second support frame, the second support frame having a second limiting groove inside;

[0008] A support assembly includes a mounting plate, an adjusting sleeve rotatably mounted on the bottom of the mounting plate, and a load-bearing frame slidably mounted inside the adjusting sleeve.

[0009] As a further improvement to the above solution, the first support frame has an internal mounting groove, a main connecting seat is fixedly installed at the top and bottom of the first support frame, and a first connecting plate is fixedly installed at both ends of the first support frame.

[0010] Through the above technical solution, the mounting groove provides a precise docking position for the subsequent mounting blocks, while the first connecting plate ensures a stable connection with external structures or equipment, improving the overall structural strength and ease of operation.

[0011] As a further improvement to the above solution, a second support frame is threadedly installed on one side of the first support frame, and an installation block is fixedly installed inside the second support frame, the installation block matching the installation groove.

[0012] By using the above technical solution, the first support frame and the second support frame are connected by threads, and the matching of the mounting block and the mounting groove is ensured, a tight connection between the two support frames is achieved. This not only enhances the stability of the overall structure, but also ensures the stability of the heating tube during the heating process, and reduces the risk of displacement caused by external forces or vibrations.

[0013] As a further improvement to the above solution, auxiliary connecting seats are fixedly installed at the top and bottom of the second support frame, and the auxiliary connecting seats are matched with the main connecting seats. Second connecting plates that match the first connecting plate are fixedly installed at both ends of the second support frame.

[0014] Through the above technical solution, the auxiliary connecting seat of the second support frame matches the main connecting seat of the first support frame, and the second connecting plate matches the first connecting plate, which further strengthens the connection between the two support frames and ensures the integrity and stability of the heating tube support structure.

[0015] As a further improvement to the above solution, the main connecting seat is internally threaded with a mounting screw, and the first support frame and the second support frame are threadedly connected by the mounting screw.

[0016] Through the above technical solution, the threaded connection of the mounting screw ensures a firm connection between the first support frame and the second support frame. This connection method not only provides sufficient structural strength, but also facilitates maintenance and disassembly, ensuring the long-term stable operation of the equipment.

[0020] Through the above technical solutions, the combination of the movable connecting rod and the adjusting sleeve, as well as the design of the locking groove and the movable slot, the flexible adjustment and stable positioning of the load-bearing frame are realized. This not only simplifies the operation process, but also ensures that the load-bearing frame can remain stable in any set position, meeting the personalized needs of the equipment under different working conditions.

[0021] As a further improvement to the above solution, the adjusting sleeve is provided with an adjusting rod inside, the outer surface of the adjusting rod is provided with a rack that matches the tooth groove, the two ends of the adjusting rod are fixedly installed with limit blocks that match the movable groove, and the bottom of the adjusting rod is fixedly installed with a load-bearing frame.

[0022] Through the above technical solutions, the cooperation between the adjusting rod and the rack, and the matching between the limiting block and the movable groove, the precise adjustment and stable support of the load-bearing frame are achieved.

[0023] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0024] This utility model completes the initial assembly between the first support frame and the second support frame by placing the heating tube in the first limiting groove and inserting the mounting block into the mounting slot. By installing the mounting screw in the main connecting seat and the auxiliary connecting seat, the installation between the main mounting component and the auxiliary mounting component is completed by using its internal threads, thus achieving the overall support effect for the heating tube. The heating tube can be easily installed on other equipment through the first connecting plate and the second connecting plate.

[0025] This invention allows the limiting block to slide under the limit of the movable groove when the adjusting rod is pulled. At the same time, the precise engagement of the toothed groove inside the adjusting sleeve with the rack ensures high precision in the adjustment process. This not only simplifies the operation steps but also greatly improves the adjustment efficiency and accuracy, ensuring that the load-bearing frame remains stable in any set position.

[0033] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0034] Example:

[0035] Please combine Figure 1-5 An electric heater with a support frame structure according to this embodiment includes a heating tube 1, a resistance wire 101 fixedly mounted on the outer surface of the heating tube 1, a connecting pipe 102 fixedly mounted on the front end of the heating tube 1, and further includes:

[0036] The main mounting component 2 includes a first support frame 201, and a first limiting groove 202 is provided inside the first support frame 201.

[0037] The auxiliary installation component 3 includes a second support frame 301, and a second limiting groove 302 is provided inside the second support frame 301.

[0038] Support component 4 includes mounting plate 401, with adjusting sleeve 405 rotatably mounted on the bottom of mounting plate 401, and load bearing frame 411 slidably mounted inside adjusting sleeve 405.

[0039] The first support frame 201 has an internal mounting groove 203. The top and bottom of the first support frame 201 are fixedly mounted with main connecting seats 204, and the two ends of the first support frame 201 are fixedly mounted with first connecting plates 206.

[0040] A second support frame 301 is threadedly installed on one side of the first support frame 201. An installation block 303 is fixedly installed inside the second support frame 301, and the installation block 303 matches the installation groove 203.

[0041] The top and bottom of the second support frame 301 are fixedly installed with auxiliary connecting seats 304, which are matched with the main connecting seat 204. The two ends of the second support frame 301 are fixedly installed with second connecting plates 305 that match the first connecting plate 206.

[0042] The main connecting seat 204 has an internal threaded mounting screw 205, and the first support frame 201 and the second support frame 301 are connected by the mounting screw 205.

[0043] After placing the heating tube 1 in the first limiting groove 202 and ensuring its stable positioning, align the mounting block 303 with the mounting groove 203 and insert it into it. At this time, the second support frame 301 and the first support frame 201 fit tightly together, completing the initial assembly. At the same time, the second limiting groove 302 inside the second support frame 301 can simultaneously limit and clamp the heating tube 1 with the first limiting groove 202.

[0044] Mounting plate 401 is fixedly installed at the bottom of the first support frame 201 and the second support frame 301. Limiting frame 402 is fixedly installed on the outer surface of mounting plate 401, and movable plate 403 is fixedly installed at the bottom of mounting plate 401.

[0045] The movable plate 403 has a movable connecting rod 404 rotatably mounted inside. An adjusting sleeve 405 is fixedly mounted at the bottom of the movable connecting rod 404. The adjusting sleeve 405 has a toothed groove 406 inside and a movable groove 407 on its outer surface.

[0046] The adjusting sleeve 405 has an adjusting rod 408 inside. The outer surface of the adjusting rod 408 has a rack 409 that matches the tooth groove 406. The two ends of the adjusting rod 408 are fixedly installed with limit blocks 410 that match the movable groove 407. The bottom of the adjusting rod 408 is fixedly installed with a load bearing frame 411.

[0047] The operator pulls the adjusting rod 408 at the bottom of the mounting plate 401. At this time, the limiting block 410 on its surface will slide under the limit of the movable groove 407. At the same time, since the locking groove 406 is provided inside the locking groove 406 and the locking groove 406 is precisely engaged with the rack 409 on the outer surface of the adjusting rod 408, it can provide stable support when the load bearing frame 411 supports the support component 4. Even if the load bearing frame 411 touches the ground, the adjusting rod 408 can remain stable and avoid accidental retraction into the adjusting sleeve 405.

[0048] The implementation principle of an electric heater with a support frame structure in this application embodiment is as follows: After placing the heating tube 1 in the first limiting groove 202 and ensuring its stable positioning, the mounting block 303 is aligned with the mounting groove 203 and inserted into it. At this time, the second support frame 301 is tightly fitted with the first support frame 201, completing the initial assembly. At the same time, the second limiting groove 302 inside the second support frame 301 can simultaneously limit and clamp the heating tube 1 with the first limiting groove 202. The resistance wire 101 on the outer surface of the heating tube 1 can facilitate the heating process of the electric heater. The connecting pipe 102 can be used to install the heating tube 1 at the external power module to ensure stable power transmission.

[0049] After the initial assembly is completed, the main connector 204 and the auxiliary connector 304 are in a mating state. Using their internal threads, the main connector 204 and the auxiliary connector 304 are installed inside by turning the mounting screw 205, thus completing the installation of the main mounting component 2 and the auxiliary mounting component 3, forming a stable support structure and ensuring the stable operation of the resistance wire 101.

[0050] After the heating tube 1 is assembled, the operator pulls the adjusting rod 408 at the bottom of the mounting plate 401. At this time, the limiting block 410 on its surface will slide under the limit of the movable groove 407. At the same time, since the locking groove 406 is provided inside the locking groove 406 and the locking groove 406 is precisely engaged with the rack 409 on the outer surface of the adjusting rod 408, it can provide stable support when the load bearing frame 411 supports the support component 4. Even if the load bearing frame 411 touches the ground, the adjusting rod 408 can remain stable and avoid accidental retraction into the adjusting sleeve 405.

[0051] When the equipment does not require overall support, the movable link 404 can be rotated inside the movable plate 403 and rotated to the bottom of the limiting frame 402. The limiting frame 402 will then hold the load-bearing frame 411 in place, ensuring that it will not move due to external forces. This allows the operator to quickly install the heating tube 1 onto other equipment via the first connecting plate 206 and the second connecting plate 305, improving the flexibility and applicability of the equipment.

[0052] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
