Description

Technical Field

[0001] This utility model relates to the field of industrial heating technology, and in particular to a tracked ceramic electric heating element. Background Technology

[0002] Ceramic electric heating elements have been widely used in various fields such as industrial production, equipment maintenance, and household appliances due to their advantages such as high temperature resistance, high thermal efficiency, and strong chemical stability. Examples include pipeline insulation and heating, mold temperature control, and heating of small household appliances. In practical applications, different scenarios have different requirements for the heating coverage and installation adaptability of the heating elements. However, existing ceramic electric heating elements have obvious technical shortcomings in structural design, making it difficult to meet the needs of multiple application scenarios.

[0003] Currently, the fixing methods for ceramic electric heating elements mainly rely on direct bolt fastening, adhesive fixing, or simple clamp fixing, which have obvious limitations: bolt fastening requires pre-drilled mounting holes on the surface of the heating target, which damages the structural integrity of the target and cannot adapt to curved or irregular surfaces; adhesive fixing relies on high-temperature resistant adhesives, which are prone to aging and peeling off under long-term high-temperature environments, causing the heating element to shift and posing a safety hazard; traditional clamp fixing is limited by the size of the clamp, making it impossible to flexibly adjust the tightness, and it is prone to loosening in vibration environments (such as when mechanical equipment is running), affecting heating stability. Most existing ceramic electric heating elements are integrated fixing structures, and their heating area is determined after manufacturing, making it impossible to flexibly adjust according to the actual size of the heating target. When dealing with non-standard sized heating objects (such as pipes of different diameters or irregularly shaped mold surfaces), if the heating element area is smaller than the target area, multiple pieces need to be spliced ​​together, which not only creates heating dead zones but also leads to uneven temperature distribution in the target area.

[0004] To address these issues, we propose a track-type ceramic electric heating element. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as small heating coverage area, and to propose a track-type ceramic electric heating element.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A tracked ceramic electric heating element, comprising a ceramic electric heating element body; A fixing plate, the top of which is fixedly connected to the bottom of the ceramic electric heating element body, and the ceramic electric heating element body is hollow inside; The top plate has two sets of external components, and the external components of the top plate are fixedly connected to the outside of the ceramic electric heating element body. The buckle has a cylindrical outer shape, and a threaded rod is provided on the outer side of the buckle, with a thread on the other end of the threaded rod. The L-shaped panel has its top fixedly connected to the bottom of the top panel, and a support column is installed inside the L-shaped panel. Telescopic components, installed on the outside of the L-shaped plate, are used to increase the heating area of ​​the heating element; A fixing component is installed on the outside of the ceramic electric heating element body to fix the heating element.

[0007] Preferably, the telescopic assembly includes an L-shaped plate, a first long rod, a first support column, a second support column, a second long rod, a third long rod, and a fourth long rod. The first support column is fixedly connected to one end of the L-shaped plate, the first long rod is rotatably connected to the outside of the first support column, and the fourth long rod is rotatably connected to the other end of the first long rod. The second support column is fixedly connected to the other end of the L-shaped plate, the second long rod is rotatably connected to the outside of the second support column, and the third long rod is rotatably connected to the outside of the second long rod.

[0008] Preferably, a short rod 2 is rotatably connected to the outer end of the long rod 2 away from the support column 2, and the outer end of the short rod 2 is rotatably connected to the top of the long rod 4, and a mounting column 2 is rotatably connected to the outer end of the long rod 4.

[0009] Preferably, the mounting column two is externally fixedly connected to a mounting bracket, the other end of the mounting bracket is fixedly connected to the mounting column one, and the mounting column one is externally rotatably connected to a long rod three.

[0010] Preferably, a short rod is rotatably connected to the outer end of the long rod four away from the mounting post two, and the outer end of the short rod one is rotatably connected to the top of the long rod two.

[0011] Preferably, the fixing component includes a buckle, a fixing block, a threaded rod, a slider, and a slotted groove. The buckle is provided on the outside of the mounting bracket.

[0012] Preferably, the threaded rod is externally rotatably connected to a handle, the buckle is externally rotatably connected inside a cross groove, and the threaded rod is slidably connected inside a slotted groove.

[0013] The beneficial effects of this utility model are: 1: Through the linkage structure of components such as the telescopic assembly, L-shaped plate, long rod support, and short rod, the expansion range can be freely adjusted according to the heating target, such as pipes of different diameters or molds of different specifications, without the need for multiple splicing pieces or the use of oversized heating elements.

[0014] 2: Through the rotational engagement of the buckle and the cross groove in the fixing component, and the sliding engagement of the threaded rod and the slotted groove, the fixing position and tightness can be flexibly adjusted. It can adapt to the installation needs of flat, curved, and irregularly shaped protruding surfaces without the need to pre-drill mounting holes on the target surface (to avoid damaging the structural integrity). The tightness of the threaded rod can be precisely controlled by the rotating handle, solving the problems of high temperature detachment of traditional adhesive fixing and vibration loosening of clamp fixing.

[0019] 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.

[0020] Reference Figure 1-3A tracked ceramic electric heating element includes a telescopic assembly comprising an L-shaped plate 11, a first long rod 12, a first support column 13, a second support column 14, a second long rod 15, a third long rod 18, and a fourth long rod 21. The first support column 13 is fixedly connected to one end of the L-shaped plate 11. The first long rod 12 is rotatably connected to the outside of the first support column 13, and the fourth long rod 21 is rotatably connected to the other end of the first long rod 12. The second support column 14 is fixedly connected to the other end of the L-shaped plate 11, and the second long rod 15 is rotatably connected to the outside of the second support column 14. The third long rod 18 is rotatably connected to the outside of the second long rod 15. A short rod 17 is rotatably connected to the outer end of the long rod 2 15 away from the support column 2 14, and the outer end of the short rod 2 17 is rotatably connected to the top of the long rod 4 21. A mounting column 22 is rotatably connected to the outer end of the long rod 4 21. A mounting bracket 20 is fixedly connected to the outer end of the mounting column 22. A mounting column 19 is fixedly connected to the other end of the mounting bracket 20, and a long rod 3 18 is rotatably connected to the outer end of the mounting column 19. A short rod 16 is rotatably connected to the outer end of the long rod 4 21 away from the mounting column 2 22, and the outer end of the short rod 16 is rotatably connected to the top of the long rod 2 15.

[0021] Mounting bracket 20 drives the mounting columns 19 and 22, which are fixed at both ends, to move outward synchronously. Mounting column 19 pulls the long rod 3 18, which is rotatably connected to it, causing the long rod 3 18 to rotate outward around its connection point with the long rod 2 15. At the same time, the long rod 2 15, with support column 2 14 as its fixed fulcrum, unfolds outward as the long rod 3 18 is pulled (the angle between the long rod 2 15 and the L-shaped plate 11 increases). Mounting column 22 pulls the long rod 4 21, which is rotatably connected to it, causing the long rod 4 21 to rotate outward around its connection point with the long rod 12. At the same time, the long rod 12, with support column 14 as its fixed fulcrum, unfolds outward as the long rod 12 unfolds outward. 3 is a fixed fulcrum, which unfolds outward as the long rod 4 21 is pulled (the angle between the long rod 1 12 and the L-shaped plate 11 increases); when the long rod 2 15 rotates outward, it drives the short rods 1 16 and 2 17 connected at both ends to deflect synchronously. The short rods 1 16 and 2 17 further pull the long rod 4 21 to maintain the synchronization of movement with the long rod 2 15, avoiding the imbalance of force on a single rod; until the mounting frame 20 moves to a position that matches the heating target size, the external force push stops. At this time, the angle of all rods is fixed, and the heating coverage area is expanded to the target size, realizing full coverage heating.

[0022] Reference Figure 1-3 The fixing components include a buckle 4, a fixing block 5, a threaded rod 7, a slider 8, and a slotted groove 9. The mounting bracket 20 is provided with a buckle 4 on the outside, the threaded rod 7 is fixedly connected to the outside of the buckle 4, and the fixing block 5 is sleeved on the outside of the threaded rod 7. The fixing block 5 has a cross groove 6 inside, and the slider 8 is fixedly connected to the outside of the fixing block 5. The slider 8 has a slotted groove 9 inside, the threaded rod 7 is rotatably connected to the outside of the handle 10, the buckle 4 is rotatably connected to the outside of the cross groove 6, and the threaded rod 7 is slidably connected to the inside of the slotted groove 9.

[0023] When the handle 10 is rotated, its threaded engagement with the threaded rod 7 generates an axial thrust, pushing the buckle 4 to press against the fixing block 5. After being pressed, the buckle 4 fits tightly against the inner wall of the cross groove 6, using friction to restrict the rotational freedom of the buckle 4. At the same time, the threaded rod 7 is pressed in the slotted groove 9, restricting its sliding displacement, thus achieving a double locking of "angle + position". By continuously tightening the handle 10, the fixing force can be adjusted according to the material hardness of the target surface, ensuring that the heating element does not loosen and avoiding excessive pressure that could damage the target surface.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
