[0002] At present, most of the telescopic rods of folding fans on the market adopt a single-rod structure. Due to the small space of a single rod, the pitch and shake structure not only needs to realize the positioning of the machine head, but also the reasonable routing of the electrical wiring. At present, most products can only realize the pitch and shake positioning of the machine head, resulting in random electrical wiring and easy wear, which reduces the service life of the wires. In addition, the shaft sleeve of the pitch and shake structure adopts an eccentrically connected rotating component. Multiple pitch operations of the machine head are likely to cause the connection shaft sleeve to collapse. As a result, the overall performance of the rotating component is poor and the service life is short. Summary of the invention

DETAILED DESCRIPTION

[0029] In order to better understand the purpose, structure and function of the present invention, the following Figure 1-12 , a shaft sleeve wire fixing assembly and an electric fan of the present invention are further described in detail.

[0030] like Figure 1-9 The present invention designs a sleeve wire fixing assembly, including a connecting tube 12, the connecting tube 12 is a three-way structure, and the coaxial ends of the connecting tube 12 are respectively provided with a first through hole 121 and a second through hole 122, the first through hole 121 and the second through hole 122 are respectively connected with a wiring sleeve 11 and a positioning sleeve 13, so that the wire can pass through the wiring sleeve 11 and the third port 125 of the connecting tube 12. The provided scheme can realize electrical standard wiring, the single-pole sleeve is partially hollowed out, the electrical wiring is simpler, the wiring is standardized, and it is not easy to wear. The whole structure is simple, and industrialization can be realized without a complex structure, and it can be used to arrange wiring on various electrical structures with rotation.

[0031] In order to facilitate disassembly and installation, the first through hole 121 and the wiring sleeve 11 are detachably connected; the second through hole 122 and the positioning sleeve 13 are detachably connected; for example, the detachable connection is achieved by plugging, sleeve connection, clamping, etc.

[0032] In the present case, taking the plug-in method as an example, the first through hole 121 and the second through hole 122 are both step-shaped structural grooves with a diameter decreasing from the outside to the inside. The inner end face of the first through hole 121 is the first positioning surface 123, and the first positioning surface 123 conflicts with the inner end face of the wiring sleeve 11; the inner end face of the second through hole 122 is the second positioning surface 124, and the second positioning surface 124 conflicts with the inner end face of the positioning sleeve 13. The step-shaped structural groove plays a blocking role in order to limit the inward movement of the inserted components.

[0033] In order to prevent the components from squeezing each other and causing the internal stress to be unable to dissipate, the first through hole 121 and the second through hole 122 are respectively designed as holes for accommodating elastic buffer components, namely, the first rubber spring hole and the second rubber spring hole. The first through hole 121 is installed with the first rubber spring 14; the second through hole 122 is installed with the second rubber spring 15. The arranged rubber spring can adopt an annular structure and be inserted into the wiring sleeve 11 and the positioning sleeve 13. The entire installation component is more stable, and part of the stress is reduced by the first rubber spring 14 and the second rubber spring 15 inside the connecting tube 12.

[0034] During the installation process, first align the first rubber spring 14 with the first through hole 121 of the connecting tube 12, press the first rubber spring 14 into the first through hole 121, until the first rubber spring 14 presses against the first positioning surface 123 in the first through hole 121, align the second rubber spring 15 with the second through hole 122 of the connecting tube 12, press the second rubber spring 15 into the second through hole 122, until the second rubber spring 15 presses against the second positioning surface 124 in the second through hole 122;

[0035] When routing the electrical wires, it is necessary to first pass the wires through the lower end of the connecting tube 12, and then pass the electrical wires out from one end of the first through hole 121. After the wiring sleeve 11 is aligned with the first through hole 121 and close to the first spring rubber hole 21, the wires are aligned with the buckle 111 in the hollowed-out part of the wiring sleeve 11, and the wires are pressed downward so that the wires pass through the buckle 111 and enter the wiring groove 113.

[0036] Specifically, the wiring is to provide a wiring groove 113 in the hollowed-out area of ​​the circumferential side wall of the wiring sleeve 11, and the wiring groove 113 is used for the wire to pass through. In addition, a fastener for fixing the wiring is also provided on the circumferential side wall of the wiring sleeve 11. The fastener in this embodiment takes the buckle 111 as an example, and the buckle 111 is set in the wiring groove 113. The buckle 111 can be a two-plate structure as shown in the figure, and the wire is clamped between the two plates, wherein the plate structure can adopt an elastic structure for easy insertion, or a common buckle can be used.

[0037] To further optimize the design, a first fixing component is provided along the axial direction of the wiring sleeve 11, and a second fixing component is provided along the axial direction of the positioning sleeve 13. The first fixing component and the second fixing component are tightly connected. Because in the actual rotation process, the eccentric force is often too large, resulting in uneven force and collapse of the entire sleeve fixing assembly. However, the complex structure is not conducive to cost. Therefore, the design preferably has a first fixing component that is a positioning hole 112 opened in the axial direction of the wiring sleeve 11, and a second fixing component that is a screw advance column 132 connected to the axial direction of the positioning sleeve 13. The screw advance column 132 is provided with a screw hole 131. The screw inserted into the screw advance column 132 is threadedly connected and tightened with the positioning hole 112. Only one screw is needed to improve the overall strength of resisting stress, the structure is simple, and the production cost is saved. It is further preferred that the positioning hole 112 is opened at the central axis position of the wiring sleeve 11, and the screw advance column 132 is integrally formed and connected to the central axis position of the positioning sleeve 13. The screws located on the same central axis are convenient for centering and assembly.

[0038] During the wiring process, in order to further reduce the possibility of friction of the wire at the bend, the end face of the screw entry column 132 opposite to the positioning hole 112 is formed into a convex shape, thereby forming an avoidance groove 133 that can pass the wire. After the wire passes through the wiring groove 113 and the buckle 111, it will pass through the avoidance groove 133 and then enter the third port 125 of the connecting tube 12 to extend. The avoidance groove 133 is an annular groove structure, and the width of the groove opening is sufficient to accommodate the width of the outer diameter of the wire to prevent the wire from being squeezed and damaged by external force.

[0039] like Figure 10-12 , an electric fan is proposed, including a support frame 2 and a fan head assembly 3, one end of the support frame 2 is connected to the above-mentioned sleeve wiring assembly, the wiring sleeve 11 and the positioning sleeve 13 are both rotatably connected to the fan head assembly 3, and one end of the support frame 2 is fixedly connected to the third port 125 of the connecting pipe 12. The support frame 2 and the fan head assembly 3 rotate and fold, or rotate and shake. During the rotation process, the rotating parts generally collapse. The sleeve wiring assembly designed by the present invention can achieve standardized electrical wiring through the provided scheme, and improve the strength of the sleeve, solve the problems of random and easy wear and difficult wiring of the electrical wiring of the single-pole shaking mechanism of the folding fan, and adopt a single-pole partial hollowing arrangement of the line, and set a positioning hole 112, a screw hole 131, and a simple structural combination of matching screws to improve the strength of resisting eccentric force during rotation. Preventing the problem of sleeve collapse caused by eccentric fixing of the sleeve during folding or shaking rotation can both standardize the wiring and improve the strength.

[0040] This design can be used in any rotatable electrical appliance, not limited to electric fans. Therefore, a rotatable electrical appliance is also proposed, including a bracket and a machine head. The bracket and the machine head are rotatably connected through the above-mentioned sleeve fixing assembly. One end of the bracket is rotatably connected to the wiring sleeve 11 and the positioning sleeve 13, and one end of the machine head is fixedly connected to the third port 125 of the connecting pipe 12. The buckle 111 structure adopts a plate-like structure of an inclined platform. Once the wire is pressed in, the wire will not fall off automatically unless it is manually taken out, ensuring the standardized wiring of the wire. The wiring groove 113 is provided with sufficient activity space. When the machine head is pitched, the wire can be moved in the wiring groove 113, avoiding the friction force acting on the same point of the wire for a long time and causing the wire to wear. After the wire enters the wiring groove 113, it only needs to pull the wire to the right through the hollowed-out part to pass through the end face of the wiring sleeve 11 to complete the wiring. Since the wire positioning structure adopts the buckle 111 limit, and the hollowed-out part area is large, the scheme can pass a larger terminal, increasing the wire terminal selectivity. After pressing the wiring sleeve 11 into the first spring rubber hole 121, press the positioning sleeve 13 into the second through hole 122, align the screw hole 131 of the positioning sleeve 13 with the positioning hole 112 of the wiring sleeve 11, and use a screw from the screw advancement column 132 of the positioning sleeve 13 to enter the screw hole 131 to connect and fix the positioning sleeve 13 and the wiring sleeve 11. This method is used to perform a central fixed connection of the sleeve to avoid the sleeve from collapsing during the rotation of the machine head.
