Description

Technical Field

[0001] This utility model relates to the field of cast aluminum heater technology, and in particular to a variable diameter cast aluminum heating coil structure. Background Technology

[0002] Cast aluminum heating coils are electric heaters that use tubular electric heating elements as the heating body. After the elements are bent and shaped, they are put into a mold and formed with high-quality metal alloy materials (such as aluminum alloy) as the outer shell. They are formed by die casting or casting processes. They can fit tightly with the heated body to achieve uniform heating and efficient heat conduction.

[0003] Existing cast aluminum heating coils are mostly customized according to the size of the heated object, making it difficult to adjust the diameter according to different heated object sizes. They need to be replaced according to the size of the heated object, which is costly.

[0004] To address this issue, we propose a variable-diameter cast aluminum heating coil structure. Utility Model Content

[0005] The purpose of this invention is to provide a variable diameter cast aluminum heating coil structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A variable diameter cast aluminum heating coil structure includes an outer ring cylinder and several arc-shaped heating plates distributed inside the outer ring cylinder. Several adjusting rods are evenly inserted through the inner and outer sides of the outer ring cylinder, and the adjusting rods are connected to the arc-shaped heating plates one by one. A screw cylinder is rotatably provided on the outer wall of the outer ring cylinder for each adjusting rod, and the screw cylinder is threadedly connected to the adjusting rod. An arc-shaped heating plate two is movably provided inside the arc-shaped heating plate one, and the arc-shaped heating plate two slides and extends on one side of the arc-shaped heating plate one.

[0008] In a further embodiment, a guide rod parallel to the adjusting rod is provided between the outer ring cylinder and the arc-shaped heating plate. One end of the guide rod is fixed to the arc-shaped heating plate, and the other end slides through to the outside of the outer ring cylinder.

[0009] In a further embodiment, the guide rod surface is provided with scale lines along the axial direction.

[0010] In a further embodiment, the adjusting rod has a hollow structure inside, and the adjusting rod is internally connected to the arc-shaped heating plate.

[0011] In a further embodiment, the upper end face of the first arc-shaped heating plate is provided with a sliding groove, and the second arc-shaped heating plate is connected with a lever that passes through the sliding groove.

[0012] In a further embodiment, a conical toothed ring is fixed to the outer end of the screw cylinder, and a conical gear is vertically meshed with the lower end of the conical toothed ring. A flat gear is coaxially connected to the lower end of the conical gear, and the flat gear meshes with the flat toothed ring rotatably mounted on the outer periphery of the outer cylinder.

[0013] In a further embodiment, a handle is connected to the lower end of the spur gear.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] This invention adjusts the space between the arc-shaped heating plates by rotating the screw cylinder, which in turn moves the adjusting rod to adjust the diameter of the heated object according to different sizes. This eliminates the need for customization and effectively saves costs. Furthermore, the second arc-shaped heating plate can be adjusted relative to the first arc-shaped heating plate to fully enclose the heated object during diameter adjustment, ensuring the heating effect.

[0021] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-2 A variable-diameter cast aluminum heating coil structure includes an outer cylinder 1 and several arc-shaped heating plates 3 distributed inside the outer cylinder 1. Specifically, at least three arc-shaped heating plates 3 are used, and the more arc-shaped heating plates 3 there are, the higher their fit with the heated object. Several adjusting rods 2 are evenly distributed through the inner and outer sides of the outer cylinder 1, and each adjusting rod 2 is connected to one of the arc-shaped heating plates 3. A screw cylinder 5 is rotatably mounted on the outer wall of the outer cylinder 1 corresponding to each adjusting rod 2. The adjusting rod 2 passes through the screw cylinder 5, and the screw cylinder 5 is connected to the adjusting rod 2. The screw rod 2 is threaded, so that when the screw cylinder 5 rotates, the adjusting rod 2 is kept stationary. At this time, under the action of the screw, the adjusting rod 2 moves closer to or away from the center of the outer ring cylinder 1, thereby adjusting the size of the space between the arc-shaped heating plates 1 and 3. The arc-shaped heating plate 2 is movably provided inside the arc-shaped heating plate 1 and 3, and the arc-shaped heating plate 2 and 4 slide on one side of the arc-shaped heating plate 1 and 3. When the space between the arc-shaped heating plates 1 and 3 gradually increases, the missing part between the arc-shaped heating plates 1 and 3 can be enclosed by pulling out the arc-shaped heating plate 2 and 4.

[0025] Please see Figure 1-3 In order to facilitate the limiting of the adjusting rod 2, a guide rod 6 parallel to the adjusting rod 2 is provided between the outer ring cylinder 1 and the arc-shaped heating plate 3. One end of the guide rod 6 is fixed to the arc-shaped heating plate 3, and the other end slides through to the outside of the outer ring cylinder 1, thereby preventing the arc-shaped heating plate 3 and the adjusting rod 2 from rotating.

[0026] Furthermore, the guide rod 6 has axial scale lines on its surface to facilitate user control and adjustment of the distance.

[0027] Please see Figure 3-4The adjusting rod 2 has a hollow structure inside, and the adjusting rod 2 is connected to the inside of the arc-shaped heating plate 3, which facilitates the laying of wires from inside the adjusting rod 2.

[0028] Please see Figure 3-4 To facilitate the sliding adjustment of the second arc heating plate 4, a groove 31 is provided on the upper end surface of the first arc heating plate 3, and a lever 41 that passes through the groove 31 is connected to the second arc heating plate 4. By pushing the lever 41 to move, the second arc heating plate 4 can be controlled to slide and extend within the first arc heating plate 3.

[0029] Please see Figure 2 To facilitate diameter adjustment, a conical toothed ring 7 is fixed to the outer end of each screw cylinder 5, and the adjusting rod 2 passes through the conical toothed ring 7. A conical gear 8 is vertically meshed with the conical toothed ring 7, and a flat gear 9 is coaxially connected to the lower end of the conical gear 8. A rotating handle 91 is connected to the lower end of the flat gear 9. A flat toothed ring 10 is rotatably installed on the outer ring cylinder 1, and the flat gear 9 and the flat toothed ring 10 mesh with each other. This allows the other flat gears 9 to rotate synchronously through the flat toothed ring 10 when one of the rotating handles 91 is rotated, without the need for separate operation and adjustment. This is more convenient and faster, and at the same time ensures the synchronicity and consistency of the adjustment of each arc-shaped heating plate 3.
