Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0047] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0048] Example 1

[0049] like Figure 1 and Figure 2 As shown, a support base includes: a base 1 and a base frame 2, the base 1 is provided with a accommodating cavity, the accommodating cavity is divided into a plurality of sliding cavities 101, the base frame 2 is slidably connected to the corresponding sliding cavities 101, so that the base frame 2 extends out of the sliding cavity 101 in a first state, wherein the base 1 has a supporting surface 102, the supporting surface 102 is opposite to the bottom wall 111 of the accommodating cavity, and the bottom wall 111 of the accommodating cavity is located in the plurality of sliding cavities 101.

[0050] The aforementioned accommodating cavity is disposed within the base 1, with multiple sliding cavities 101 arranged side by side, and the bottom wall of the sliding cavity 101 is a portion of the accommodating cavity bottom wall 111. When the base 1 can be used for support, the accommodating cavity bottom wall 111 is opposite the supporting surface 102, so that after the base frame 2 slides out of the corresponding sliding cavity 101, it can jointly play a supporting role with the base 1. The state in which the base frame 2 extends out of the sliding cavity 101 is the first state. In particular, when the support base is placed on an inclined slope, the contact area between the support base and the ground can be increased, thereby strengthening the friction between the support base and the ground and ensuring the stability of the product on inclined platforms and flat ground.

[0051] Further, continue to combine Figure 1 As shown, the multiple base frames 2 are relatively far apart in the first state, and the multiple base frames 2 are respectively retracted into the corresponding sliding cavities 101 in the second state.

[0052] The above-mentioned arrangement includes multiple chassis 2, each chassis 2 corresponding to a sliding cavity 101. When the chassis 2 slides out of the corresponding sliding cavity 101, it is relatively far away from another adjacent chassis 2, so that the chassis 2 can expand the support area, making the support structure of the support base more stable and the support effect better. The state in which the chassis 2 is retracted into the corresponding sliding cavity 101 is the second state. When the chassis 2 is retracted into the corresponding sliding cavity 101, the support base can be restored to its original state, wherein the support surface 102 is a plane and can be used to be placed on a flat ground. When the chassis 2 is retracted into the sliding cavity 101, the support base can be stably supported on a flat ground, which also ensures the aesthetic appearance.

[0053] Furthermore, if Figure 2 and Figure 5 As shown, the inlet and outlet of the sliding cavity 101 are arc-shaped, and the peripheral side of the base frame 2 has an arc-shaped surface, which allows the base frame 2 to be retracted into the corresponding sliding cavity 101.

[0054] The curvature of the entrance and exit of the sliding cavity 101 is consistent with the curvature of the corresponding chassis 2, so that the chassis 2 can be completely retracted into the corresponding sliding cavity 101. The chassis 2 has a curved peripheral side, so that the chassis 2 can further expand the contact area with the ground.

[0055] Furthermore, if Figure 2 As shown, the base frame 2 and the sliding cavity 101 respectively have a fan-shaped structure. The base frame 2 with a fan-shaped structure has the same radius and the arc length is a part of the circumference, so that the overall structure of the base frame 2 is more stable and the support stability of the support base can be improved.

[0056] Further, if Figure 2 As shown, the base 1 includes: a base 11 and a cover plate 12. The base 11 is provided with a step surface. The cover plate 12 is connected to the base 11. The side surface of the cover plate 12 facing the step surface and the step surface enclose an accommodating cavity.

[0057] The above-mentioned base 11 has a base surface, and a boss 112 is provided on the base surface. The top surface of the boss 112 forms a step surface with the base surface, wherein the boss 112 is arranged into a frame structure to reduce weight, and a threaded column with an internal thread is provided in the boss 112 for detachably connecting with the cover plate 12 through a thread. The base surface is a plane, and a threaded column with an internal thread is also provided on the base surface for threaded connection with the cover plate 12 to form a receiving cavity. In addition, when the base has an arc-shaped circumferential side, the base 11 and the cover plate 12 also have an arc-shaped circumferential side, and the base 11 and the cover plate 12 respectively have a fan-shaped structure. The circumferential side of the base 11 includes an arc-shaped surface and a plane, and the arc-shaped surface is between the two planes, so that the base 11 forms a fan-shaped structure. The boss 112 can be arranged at the angle formed by the two planes of the base 11.

[0058] By configuring the base 1 as a split structure of a base 11 and a cover plate 12 and detachably connecting them, the chassis 2 can be easily installed and connected. In order to reduce weight, the chassis 2 is also configured as a frame structure. Specifically, the chassis 2 may include two side panels and an arc-shaped plate, the two side panels forming an angle, and the two ends of the arc-shaped plate are respectively connected to the two side panels in a one-to-one correspondence. The two side panels and the arc-shaped plate can enclose a trough body, and a plurality of mutually intersecting ribs can be provided in the trough body to strengthen the structure of the chassis 2. Among them, the ribs include arc-shaped ribs and rectangular ribs.

[0059] Further, if Figure 2 As shown, the support base also includes: a guide rail assembly 3, wherein a mounting groove 21 extending in the extension direction of the base frame 2 is provided on the side of the bottom wall of the base frame 2 facing the accommodating cavity, and the guide rail assembly 3 is provided in the mounting groove 21 and connected to the base frame 2.

[0060] The guide rail assembly 3 is arranged in the installation groove 21, and the installation groove 21 can limit and connect the guide rail assembly 3 so that the base frame 2 can slide synchronously with the guide rail assembly 3 along a predetermined direction.

[0061] Further, if Figure 3 As shown, the guide rail assembly 3 includes: a guide rail 31 and a slide rail 32 , the guide rail 31 is connected to the base 11 , the slide rail 32 is slidably connected to the guide rail 31 , and the slide rail 32 is detachably connected to the base frame 2 .

[0062] The guide rail 31 can be connected to the base 11 by screws, and the slide rail 32 slides on the guide rail 31, and the guide rail 31 can play a guiding role of the slide rail 32. The slide rail 32 is connected to the base frame 2 so that the base frame 2 can slide synchronously with the slide rail 32.

[0063] Furthermore, if Figure 3 and Figure 4 As shown, the guide rail 31 includes: an outer rail 311, a ball nest 312, a first ball 313 and a second ball. The outer rail 311 has a slide groove 3101, and one end of the slide groove 3101 is provided with a plurality of first balls 313 on opposite sides along the extension direction of the slide groove 3101. The ball nest 312 is provided at the other end of the outer rail 311, and the opposite sides of the bead nest 312 are provided with a plurality of second balls along the extension direction of the slide groove 3101. The slide rail 32 has two opposite sides, which are suitable for contacting with the first balls 313 and the second balls on the corresponding sides.

[0064] The outer rail 311 has two opposing side panels, with a base plate located between them. The base plate is connected to the base 11, and a slot 3101 is formed between the two side panels. The slot 3101 serves as a position limiter for the slide rail 32. One end of the slot 3101 has a ball hole for receiving a first ball 313, while the other end has a ball nest 312. The center of the ball nest 312 is raised, forming a groove within the nest that clamps the sidewall of the slide rail 32, thus limiting the movement of the slide rail 32. The two sidewalls of the ball nest 312 are provided with ball holes for receiving a second ball. Therefore, the slide rail 32 can slide in contact with the ball at both ends of the slot 3101, preventing the slide rail 32 from getting stuck. Furthermore, the sidewalls of the slide rail 32 have recesses that contact and limit the ball. Similarly, recessed portions are also provided on the side walls of the ball nest 312 and the outer rail 311 , which also serve to limit the position of the balls.

[0065] Furthermore, if Figure 3 As shown, the outer rail 311 is provided with a limiting structure 33 at the end portion where the bead nest 312 is provided, and the slide rail 32 can abut against the limiting structure 33 .

[0066] The aforementioned limiting structure 33 may be a limiting plate, which is disposed on the inner side of the slide groove 3101 to limit the sliding position of the slide rail 32 .

[0067] A buckle 22 is provided at one end of the mounting slot 21 , and a clamping slot 321 is provided on the slide rail 32 . The clamping slot 321 is engaged with the buckle 22 .

[0068] The above-mentioned clip 22 is arranged on the bottom of the installation groove 21. Specifically, the clip 22 is arranged on the outside of the base frame 2, so that after the base frame 2 extends out of the sliding cavity 101, the clip 22 can be synchronously located outside the sliding cavity 101. Therefore, it is convenient to press the clip 22 to make the clip 22 engage or disengage with the slot 321, which facilitates the installation, disassembly, maintenance and replacement of the base frame 2.

[0069] When assembling the above-mentioned support base, first embed the second ball in the bead nest 312, then install the slide rail 32 and the bead nest 312 together on the outer rail 311 to ensure the smoothness of the slide rail 32 during the pulling and pulling process, then connect the base frame 2 corresponding to the slide rail 32 in the guide rail assembly 3 through the buckle 22 and the slot 321, and then fix the connected guide rail assembly 3 and the base frame 2 together with screws, and finally fix the cover plate 12 and the base frame 2 together with screws to complete the assembly of the support base.

[0070] The outer rail 311 of the guide rail assembly 3 limits the extension and retraction of the slide rail 32. Once the base frame 2 is connected to the guide rail assembly 3 and screwed to the base frame 2, the support base can be extended and retracted. When extended, the support base ensures the stability of the vertical electric heater on the inclined platform, preventing the heater from tipping over due to an unstable center of gravity. When retracted, the support base is mounted on the vertical electric heater, ensuring its aesthetically pleasing appearance and stability on flat ground.

[0071] Example 2

[0072] An electric heater comprises a main structure and any one of the support bases, wherein the support base is suitable for supporting the main structure.

[0073] The above-mentioned electric heater can be a skirting board electric heater that can be used vertically or horizontally. When the skirting board electric heater is in a vertical position, the support base can play a supporting role, thereby improving the adaptability of the skirting board electric heater to the environment and being able to be placed more stably on a sloping ground.

[0074] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
