[0015] A further technical solution is that the third stop surface and the first stop surface extend along the axial direction of the electrical appliance connecting pipe; and the third sliding surface and the first sliding surface are inclined surfaces.
[0016] Its further technical solution is that the fourth locking portion is provided with a fourth stop surface and a fourth sliding surface.

[0036] The disclosure below provides many different embodiments or examples for realizing different structures of the present invention. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention may repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.
[0037] In the design and use of vertical household appliances such as vertical fans and vertical electric heaters, in order to make their functional parts align with the human body, they usually need to be connected and supported by threaded plastic or hardware pipes. Although the structure of using threaded pipes to connect supports is easy to disassemble and transport at any time, and has great advantages in cost and stability, when installing threaded pipes, the torque applied by the operator is often different, which causes the threaded pipes to easily produce angle deviation during the tightening process. Not only does it make the orientation of the threaded pipe parts inconsistent, affecting the user experience, it may even cause thread wear due to excessive tightening force, thereby affecting the service life of the thread.
[0038] Therefore, in order to solve the technical problem that the existing threaded pipes are prone to angular deviation during the tightening process, resulting in inconsistent orientation of the threaded pipe components, which may cause thread wear due to excessive tightening force, thereby affecting the service life of the threads, the present application provides an electrical device that can prevent the threads from being damaged due to excessive tightening and increase the service life of the threads. Please refer to the following embodiments for details.
[0039] The technical solutions in the implementation scheme of the utility model will be clearly and completely described below in conjunction with the accompanying drawings in the implementation scheme of the utility model.
[0040] The present utility model embodiment provides an electrical device 10, comprising:
[0041] The electrical device body 100 is provided with an electrical connection pipe 110 , and the electrical connection pipe 110 is provided with a first threaded portion 120 and a first locking portion 130 , which are arranged in sequence along the axial direction of the electrical connection pipe 110 .
[0042] The base 200 is provided with a base connecting tube 210, and the base connecting tube 210 is provided with a second threaded portion 220 and a second locking portion 230. The second threaded portion 220 and the second locking portion 230 are arranged in sequence along the axial direction of the base connecting tube 210, and the second threaded portion 220 is detachably connected to the first threaded portion 120.
[0043] When the second threaded portion 220 is connected to the preset position of the first threaded portion 120, the second locking portion 230 and the first locking portion 130 stop and cooperate in the first direction, and the second locking portion 230 and the first locking portion 130 slide and cooperate in the second direction, and the first direction is opposite to the second direction.
[0044] In this way, by providing the first locking portion 130 and the second locking portion 230, when the base connecting tube 210 is screwed in the first direction and the second threaded portion 220 is screwed into the first threaded portion 120 to a preset position, the stop cooperation of the first locking portion 130 and the second locking portion 230 will generate obvious resistance, so that the user can quickly perceive the obvious resistance and stop tightening; and because the cooperation of the first locking portion 130 and the second locking portion 230 can limit the maximum tightening degree of the thread, once the preset stop position is reached, even if the user continues to tighten, the tightening force that continues to be applied will no longer act on the thread, but will be absorbed by the locking mechanism, so that it can be ensured that the electrical connecting tube 110 and the base connecting tube 210 are in the same state each time they are assembled, and fundamentally prevent the stress concentration and damage of the thread caused by over-tightening; in addition, when the base connecting tube 210 is screwed in the second direction, the sliding cooperation of the second locking portion 230 and the first locking portion 130 in the second direction can facilitate the smooth removal of the base connecting tube 210 from the electrical connecting tube 110.
[0045] It can be understood that the first direction can be a clockwise direction around the axis of the electrical connecting tube 110, and correspondingly, the second direction can be a counterclockwise direction around the axis of the electrical connecting tube 110; or, the first direction can be a counterclockwise direction around the axis of the electrical connecting tube 110, and correspondingly, the second direction can be a clockwise direction around the axis of the electrical connecting tube 110.
[0046] In some implementations, the electrical device 10 may be a fan, an electric heater, etc. The following embodiments of the present application are described using a fan as an example.
[0047] When the electrical device 10 is a fan, the electrical device body 100 is the fan body, and the electrical device connecting pipe 110 is the fan connecting pipe.
[0048] In some embodiments, the first locking portion 130 is provided with a first stop surface 131 and a first sliding surface 132, and the second locking portion 230 is provided with a second stop surface 231 and a second sliding surface 232; when the second threaded portion 220 is connected to the preset position of the first threaded portion 120, the first stop surface 131 and the second stop surface 231 are arranged relative to each other and stop in cooperation.
[0049] When the user twists the base connecting tube 210 along the first direction, the first stop surface 131 and the second stop surface 231 stop cooperation, that is, the second stop surface 231 and the first stop surface 131 contact each other, and the second stop surface 231 can block the first stop surface 131 from moving along the first direction, thereby helping to achieve the stop cooperation between the first locking portion 130 and the second locking portion 230 in the first direction, and further helping the user to quickly perceive the obvious resistance and stop the twisting operation.
[0050] The first sliding surface 132 and the second sliding surface 232 are arranged opposite to each other and slide in cooperation. When the user twists the base connecting tube 210 in the second direction, the first sliding surface 132 and the second sliding surface 232 slide in cooperation, that is, the second sliding surface 232 and the first sliding surface 132 contact each other, the first sliding surface 132 can slide with the second sliding surface 232, and the first sliding surface 132 can move in the second direction, thereby facilitating the first locking portion 130 and the second locking portion 230 to slide in cooperation in the second direction, thereby facilitating the user to smoothly disassemble the base connecting tube 210.
[0051] In some embodiments, the first stop surface 131 and the second stop surface 231 extend along the axial direction of the appliance connecting tube 110 , thereby helping the second stop surface 231 to generate an effective blocking force to prevent the first stop surface 131 from moving along the first direction.
[0052] The first sliding surface 132 and the second sliding surface 232 are inclined surfaces. Thus, when the user twists the base connecting tube 210 along the second direction, the inclined surface can act as a guide structure, which helps the user to smoothly twist the base connecting tube 210. In addition, the inclined surface not only improves the convenience of the user to disassemble the base connecting tube 210, but also reduces the possibility of jamming or sudden loosening during the opening process.

[0056] When the fourth threaded portion 420 is connected to the preset position of the second threaded portion 220, the fourth locking portion 430 and the second locking portion 230 stop and cooperate in the first direction, and the fourth locking portion 430 and the second locking portion 230 slide and cooperate in the second direction, and the first direction is opposite to the second direction.
[0057] By providing a detachable intermediate connecting tube 310, the user can easily adjust the height of the fan 10 according to actual needs, achieving free height adjustment, which greatly improves the adaptability of the product and user satisfaction. In addition, the detachable intermediate connecting tube 310 allows the fan 10 to be disassembled when not in use, thereby reducing the space occupied by the fan 10 and facilitating transportation.
[0058] In some embodiments, the third locking portion 330 is provided with a third stop surface 331 and a third sliding surface 332. When the third threaded portion 320 is connected to the preset position of the first threaded portion 120, the third stop surface 331 and the first stop surface 131 are arranged relative to each other and stop fit, and the third sliding surface 332 and the first sliding surface 132 are arranged relative to each other and slide fit.
[0059] In some embodiments, the third stop surface 331 and the first stop surface 131 extend along the axial direction of the appliance connecting tube 110 ; the third sliding surface 332 and the first sliding surface 132 are inclined surfaces.
[0060] In some embodiments, the fourth locking portion 430 is provided with a fourth stop surface 431 and a fourth sliding surface 432.
