Abstract
Description
Technical Field
[0001] The present application relates to the technical field of connecting plugs, and in particular to a universal swivel tail rotating head. Background Art
[0002] With the booming hairdressing industry and rapidly advancing technology, hairdressing equipment is gradually entering a new stage of high diversification and intelligence. In this context, the importance of the swivel plug, as a key power connection component, is self-evident. The swivel plug was originally designed to overcome the connection inconvenience caused by the fixed direction of traditional plugs. Through its flexible rotation mechanism, it enables hairdressing equipment to enjoy greater convenience and efficiency when connecting to the power supply, thereby improving the overall user experience.
[0003] In the related art, the rotating plug is exquisitely designed and includes a plug body, a connecting cable and an insulating shell. The plug body is electrically connected to the cable, and the insulating shell protects the connection. The plug body is provided with a circular protrusion, on which a guide rod is fixed, and a conductive sleeve is fixed on the outer periphery, both of which have circular cross-sections. The hairdressing equipment is equipped with a socket for inserting the conductive sleeve, and a conductive protrusion is fixed on the inner wall of the conductive sleeve, and the conductive rod is aligned with and inserted into the guide socket on the socket. In the socket, the conductive protrusion is in close contact with the conductive sleeve, and the conductive pin fixed in the guide socket is in close contact with the conductive rod to ensure stable power supply. The special feature is that the plug body can rotate freely in the socket, maintaining electrical connection while meeting multi-angle operation requirements.
[0004] However, while existing technologies offer significant advantages in resolving directional issues, in actual use, hairdressing equipment often requires complex and variable adjustments in grip angles and positions. This frequently subjects the connection between the cable and the insulation housing to bending stress, which can easily wear and tear the insulation over time. This not only affects the aesthetics of the device but can also lead to safety hazards such as short circuits and electric shocks, posing a threat to the user's life and property. Utility Model Content
[0005] The purpose of this application is to provide a universal swivel tail rotating head to solve the problem in the above-mentioned related technology that the insulation skin of the connecting cable close to the insulating shell part is worn or even broken after long-term use.
[0006] The present application provides a universal tail rotating head adopting the following technical solutions:
[0007] A universal swivel tail rotating head includes a plug-in body and a connecting cable, the connection between the plug-in body and the connecting cable is covered with an insulating shell; the insulating shell includes a fixed sleeve close to the plug-in body and a bending sleeve connected to one end of the fixed sleeve, and the bending sleeve fixed sleeve is arranged on the outer circumference of the connecting cable; a plurality of groove structures are evenly arranged on the outer circumference of the bending sleeve along its own length direction, and adjacent groove structures are staggered. The groove structure includes two bending grooves with the same cross-section symmetrically opened on the outer circumference of the bending sleeve.
[0008] By adopting the above technical solution, due to the staggered setting of the bending groove, the bending sleeve has good bending performance, that is, the connecting cable in the bending part can be bent in multiple directions. Therefore, when the connection cable and the plug-in body are bent at the junction, the area of the bending part is bent, and the bending part can protect the connecting cable in this area, so it can reduce the possibility of damage or tearing of the cable at the junction of the connecting cable and the bending part, thereby reducing the corresponding safety hazards.
[0009] Optionally, the plurality of bending grooves on the outer periphery of the bending sleeve close to the end of the fixing sleeve are grooves.
[0010] By adopting the above technical solution, external gas cannot directly contact the corresponding connecting cable insulation through the bending groove of the bending sleeve close to the fixed sleeve. Although it will cause poor bending performance here, it will also improve the structural strength of the bending sleeve close to the fixed sleeve and extend the corresponding service life.
[0011] Optionally, two adjustment slots are symmetrically provided on the bottom sides of a plurality of bending grooves near the middle of the bending sleeve.
[0012] By adopting the above technical solution, external gas can directly contact the corresponding connecting cable insulation through the two adjustment grooves on the bottom side of the bending trough in this area. The bending performance here is better, which improves the performance of the universal swivel tail rotating head.
[0013] Optionally, a plurality of bent grooves on the outer periphery of the end portion of the bending sleeve away from the fixing sleeve are connecting grooves.
[0014] By adopting the above technical solution, external gas can directly contact the corresponding connecting cable insulation through the bending groove in this area. The bending performance here is the best, further improving the performance of the universal swivel tail rotating head.
[0015] Optionally, the bending sleeve is fixed with a flexible convex ring mounted on the outer circumference of the connecting cable at the end away from the fixed sleeve, and two positioning grooves are symmetrically opened on the outer circumference of the connection between the flexible convex ring and the bending sleeve, and the two positioning grooves are staggered with the two bending grooves closest to the flexible convex ring.
[0016] By adopting the above technical solution, the bending performance of the connection point between the connecting cable and the bending sleeve is guaranteed, and at the same time, the possibility of the insulation skin on the connecting cable being damaged due to bending is reduced by the flexible protrusion.
[0017] Optionally, the outer sleeve of the connecting cable is provided with a limiting sleeve, a positioning strip is fixedly provided on the inner wall of the opening of the limiting sleeve facing the insulating shell, and a positioning slot for inserting the positioning strip is provided on the outer periphery of the flexible convex ring.
[0018] By adopting the above technical solution, due to the installation arrangement of the limit sleeve, the connection point between the connecting cable and the bending sleeve is further protected, further reducing the possibility of damage due to bending at this point.
[0019] Optionally, a plurality of anti-slip grooves are fixed on the outer periphery of the limiting sleeve.
[0020] By adopting the above technical solution, it is convenient to hold the outer peripheral surface of the limiting sleeve when installing the limiting sleeve, thereby reducing the difficulty of installing the limiting sleeve.
[0021] Optionally, an elastic sealing strip is provided on the side of the insulating shell, and an annular groove for inserting the elastic sealing strip is provided on the outer periphery of the limiting sleeve.
[0022] By adopting the above technical solution, after the insulating shell is installed, the elastic sealing strip is installed inside the annular groove on the outer periphery of the limiting sleeve, thereby improving the installation stability of the limiting sleeve and reducing the possibility of the limiting sleeve becoming loose during installation.
[0023] In summary, this application includes at least one of the following beneficial technical effects:
[0024] 1. Due to the staggered setting of the bending groove, when the connection cable and the plug-in body are bent at the joint, the area of the bending portion is bent, and the bending portion can protect the connection cable in this area, thereby reducing the possibility of damage or tearing of the cable at the joint between the connection cable and the bending portion, reducing the corresponding safety hazards.

DETAILED DESCRIPTION
[0034] The present application is further described in detail below in conjunction with all the accompanying drawings.
[0035] Example 1:
[0036] Reference Figure 1 and Figure 2 A universal swivel tail rotating head includes a plug body 1 and a connecting cable 2. The connection between the plug body 1 and the connecting cable 2 is covered with an insulating shell 3; the insulating shell 3 includes a fixing sleeve 31 close to the plug body 1 and a bending sleeve 32 integrally injection-molded with one end of the fixing sleeve 31, wherein the bending sleeve 32 and the fixing sleeve 31 are arranged on the outer periphery of the connecting cable 2;
[0037] During the assembly of the rotary head, the insulation of the end of the connecting cable 2 is stripped off in advance to expose the core wire so as to electrically connect it to the plug body 1, and then the insulating shell 3 is covered on the periphery of the connection between the two.
[0038] Reference Figure 2 and Figure 3A plurality of groove structures 321 are evenly opened on the outer periphery of the bending sleeve 32 along its own length direction, and adjacent groove structures 321 are staggered 90 degrees, wherein the groove structure 321 includes two bending grooves 3211 symmetrically arranged on the same cross section of the outer periphery of the bending sleeve 32.
[0039] Reference Figure 3 and Figure 4 The bending sleeve 32 is divided into three areas, namely the area close to the fixing sleeve 31, the area in the middle of the bending sleeve 32, and the area of the fixing sleeve 31; the multiple bending grooves 3211 on the outer periphery of the end of the bending sleeve 32 close to the fixing sleeve 31 are grooves, and the external gas cannot pass through the bending grooves 3211 in this area to directly contact the insulation skin of the corresponding connecting cable 2, and the bending performance here is poor; the multiple bending grooves 3211 near the middle of the bending sleeve 32 are symmetrically provided with two adjustment grooves 3121 on the bottom side, and the external gas can pass through the two adjustment grooves 3121 on the bottom side of the bending grooves 3211 in this area to directly contact the insulation skin of the corresponding connecting cable 2, and the bending performance here is good;
[0040] The several bending grooves 3211 on the outer periphery of the end of the bending sleeve 32 away from the fixed sleeve 31 are connecting grooves, that is, the external gas can directly contact the corresponding insulation skin of the connecting cable 2 through the bending grooves 3211 in this area, and the bending performance here is the best; with this arrangement, the bending performance of the bending sleeve 32 gradually increases in the direction away from the fixed sleeve 31, and the adjacent groove structures 321 are staggered 90 degrees, so that the bending part can be bent in multiple directions.
[0041] Reference Figure 3 The bending sleeve 32 is integrally formed with a flexible convex ring 33 on the outer periphery of the connecting cable 2 at the end away from the fixed sleeve 31, and two positioning grooves 331 are symmetrically provided on the outer periphery of the connection between the flexible convex ring 33 and the bending sleeve 32. The two positioning grooves 331 are staggered 90 degrees with the two bending grooves 3211 closest to the flexible convex ring 33, thereby ensuring the bending performance of the connection between the connecting cable 2 and the bending sleeve 32, and at the same time reducing the possibility of damage to the insulation skin of the connecting cable 2 due to bending through the flexible protrusion.
[0042] The implementation principle of the embodiment of this application is:
[0043] When the universal swivel tail rotating head is used, since the bending performance of the bending sleeve 32 gradually increases in the direction away from the fixed sleeve 31, the adjacent groove structures 321 are staggered 90 degrees, so that the connecting cable 2 in the bending part can be bent in multiple directions, and the bending part can protect the connecting cable 2 in this area, thereby reducing the possibility of damage or tearing of the cable at the junction of the connecting cable 2 and the bending part.
[0044] Example 2:
[0045] Reference Figure 5 、 Figure 6 and Figure 7 The difference between the embodiment of the present application and embodiment 1 is that the outer sleeve of the connecting cable 2 is provided with a limiting sleeve 4, wherein the limiting sleeve 4 is made of flexible rubber material, and a positioning strip 41 is integrally formed on the inner wall of the opening of the limiting sleeve 4 facing the insulating shell 3, and a positioning slot 332 for inserting the positioning strip 41 is provided on the outer periphery of the flexible convex ring 33.
[0046] The outer circumference of the limiting clamp 4 is integrally formed with a plurality of anti-slip grooves 42, which facilitate gripping the outer circumference of the limiting clamp 4 when installing the limiting clamp 4, thereby reducing the difficulty of installing the limiting clamp 4. The side of the insulating shell 3 is provided with an elastic sealing strip 5 made of rubber material, and an annular groove 43 for inserting the elastic sealing strip 5 is opened on the outer circumference of the end of the limiting clamp 4 away from the bend.
