Description

Technical Field

[0001] This utility model relates to the field of power connection cable technology, specifically a power connection cable that is easy to extend and store. Background Technology

[0002] In today's electronic device usage scenarios, power cables are an indispensable accessory, and their ease of use and storage are receiving increasing attention from users. Whether at home, in the office, or outdoors, multi-cable power cables are widely used to connect various electronic devices, such as computers, printers, projectors, and chargers. However, traditional multi-cable power cables have many problems in terms of use and storage.

[0003] A search revealed that patent publication number CN219554101U discloses a retractable power cord, belonging to the field of power cord technology. The cord includes a housing with a rotating shaft inside. The right end of the shaft passes through the housing and is rotatably connected to it via a bearing. The power cord body is housed within the housing, passing through the rotating shaft and wrapping around its outer surface. In use, this invention, with its housing, rotating shaft, rectangular groove, rectangular block, recess, tension spring, concave disc, pin, and slot, allows for convenient retraction and storage of the power cord. Furthermore, the pin and slot work together to limit the rotation of the shaft, preventing it from rotating and affecting the retraction and storage effect. This structure provides the power cord body with a retractable storage function during use, solving the problem of existing power cord bodies lacking this function, thus meeting customer needs.

[0004] Existing retractable power cables, while designed for easy storage, typically only allow for the retraction and storage of individual cable bundles. Multi-bundle power cables, with their bundles intertwined and lacking effective retractable storage structures, make it inconvenient to locate and separate the required bundles, impacting efficiency. For example, in an office setting, multi-bundle power cables connecting a computer, monitor, and printer can be extremely time-consuming to untangle when only the printer's power cable needs replacing. Furthermore, excessively long bundles, if left haphazardly, not only occupy significant space but also create a chaotic and potentially damaging environment. Therefore, a retractable power cable design is needed. Utility Model Content

[0005] In view of the defects or shortcomings of power cords that are easy to extend and store, the purpose of this utility model is to provide a power cord that is easy to extend and store, which can extend and store the wires of a multi-wire power cord individually or in multiple bundles, thus avoiding the tangling and knotting of the wires in the multi-wire power cord.

[0006] To achieve the above-mentioned objectives, the present invention adopts the following technical solution:

[0007] This utility model provides a power connection cable that is easy to extend and store, including a multi-wire harness power connection cable, wherein the multi-wire harness power connection cable is provided with a wire harness extension and storage mechanism for storing a single wire harness or multiple wire harnesses.

[0008] The wire harness telescopic storage mechanism is composed of an upper shell, a lower shell, and a rotating assembly. The rotating assembly is arranged in a rectangular array on the upper shell, and the inner side of the lower shell is provided with winding posts arranged in a rectangular array.

[0009] The rotating assembly is provided with a rotating plate, which is located at the top of the upper housing. An annular mounting plate is provided on the inner side of the rotating plate. Mounting grooves are provided on both sides of the bottom of the annular mounting plate. An end wall spring at one end of the mounting groove is connected to a ball. A plum blossom-shaped limiting groove is provided at the bottom of the rotating plate.

[0010] Preferably, the upper housing is installed at the top of the lower housing, and the upper housing and the lower housing are fixedly connected by fastening bolts. The upper housing is provided with a first semi-annular inlet / outlet pipe on both outer walls, and the lower housing is provided with a second semi-annular inlet / outlet pipe on both outer walls.

[0011] Preferably, a connecting shaft is provided at the center of the end wall of the other end of the winding post, and the other end of the connecting shaft is installed in a bearing on the bottom end of the lower housing.

[0012] Preferably, the annular mounting plate is fixedly connected to the upper housing by fastening bolts.

[0013] Preferably, a slot is provided on the end wall of one end of the winding post;

[0014] A rotating shaft is provided at the center of the bottom inner side of the rotating plate. The bottom end of the rotating shaft passes through the center of the surface of the annular mounting plate and the bearing on the top of the upper housing, and extends to the inner side of the upper housing to connect with the locking block.

[0015] Preferably, the plum blossom-shaped limiting groove is composed of an annular array of arc-shaped grooves and arc-shaped protrusions.

[0016] Compared with existing technologies, one or more of the above technical solutions have the following beneficial effects:

[0017] 1. In this utility model, through a series of structural arrangements, the wire harness telescopic storage mechanism is equipped with multiple rotating components and winding posts. After the user inserts multiple wire harnesses from the multi-wire harness power connection line into the slots on the multiple winding posts, the user then fixes the upper and lower housings together, with the locking block located in the slot. When the user needs to store a specific wire harness from the multi-wire harness power connection, the user rotates the rotating component corresponding to the desired wire harness. When the user rotates the rotating plate on the rotating component, it drives the locking block to rotate. The rotating plate rotates the winding post, which winds and stores the wire harness. When the user wants to unwind the wound wire harness, they can do so by rotating the rotating plate and pulling both ends of the wire harness. This allows users to easily store single or multiple wire harnesses on multi-wire power connection cables, making it easier to find and separate the required wire harness. It also prevents the wire harnesses on multi-wire power connection cables from getting tangled or knotted, and avoids the problem of excessively long wire harnesses being placed randomly and taking up a lot of space.

[0018] 2. In this utility model, the combination of structures such as a rotating plate, annular mounting plate, spring, ball, and plum blossom-shaped limiting groove can limit the rotation of the rotating plate, thus preventing the winding post from rotating when the rotating plate rotates, which could cause the wound wire bundle to become loose and jam.

[0035] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0036] It should be noted that the following detailed description is exemplary and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0037] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0038] like Figure 1-9 As shown, a power cable that is easy to extend and store includes a multi-wire harness power cable 100, and the multi-wire harness power cable 100 is provided with a wire harness extension and storage mechanism 200 for storing a single wire harness or multiple wire harnesses.

[0039] The wire harness telescopic storage mechanism 200 is composed of an upper housing 210, a lower housing 220 and a rotating component 230. The rotating component 230 is arranged in a rectangular array on the upper housing 210, and the inner side of the lower housing 220 is provided with winding posts 222 arranged in a rectangular array. The cooperation of multiple rotating components 230 and multiple winding posts 222 can telescopically store a single wire harness or multiple wire harnesses.

[0040] A rotating plate 231 is provided on the rotating assembly 230, and the rotating plate 231 is located on the top of the upper housing 210. An annular mounting plate 232 is provided on the inner side of the rotating plate 231. Mounting grooves 2321 are provided on both sides of the bottom of the annular mounting plate 232. The end wall spring 233 at one end of the mounting groove 2321 is connected to the ball 234. A plum blossom-shaped limiting groove 2311 is provided at the bottom of the rotating plate 231. The plum blossom-shaped limiting groove 2311 is composed of an annular array of arc-shaped grooves and arc-shaped protrusions. When the rotating plate 231 rotates, the arc-shaped protrusions on the plum blossom-shaped limiting groove 2311 will exert a certain squeezing force on the ball 234, and the ball 234 will be subjected to a certain squeezing force. After the pressure is applied, it will move into the mounting groove 2321. When the arc groove on the plum blossom-shaped limiting groove 2311 moves to be aligned with the mounting groove 2321, the ball 234 will move partially into the inner side of the arc groove under the action of the spring 233's rebound force. When the rotating plate 231 does not rotate, the rotation of the rotating plate 231, the annular mounting plate 232, the spring 233, the ball 234, the plum blossom-shaped limiting groove 2311 and other structures can play a certain limiting role, which can prevent the rotating plate 231 from rotating and causing the winding post 222 to rotate, resulting in the wound wire bundle becoming loose and jammed.

[0041] The upper housing 210 is installed on the top of the lower housing 220, and the upper housing 210 and the lower housing 220 are fixedly connected by fastening bolts. The upper housing 210 is provided with a first semi-annular inlet / outlet pipe 211 on both outer walls, and the lower housing 220 is provided with a second semi-annular inlet / outlet pipe 221 on both outer walls.

[0042] A connecting shaft is provided at the center of the end wall of the other end of the winding post 222, and the other end of the connecting shaft is installed in the bearing on the bottom end of the lower housing 220.

[0043] The annular mounting plate 232 is fixedly connected to the upper housing 210 by fastening bolts.

[0044] A slot 2221 is provided on the end wall of one end of the winding post 222;

[0045] A rotating shaft 235 is provided at the center of the bottom inner side of the rotating plate 231. The bottom end of the rotating shaft 235 passes through the center of the surface of the annular mounting plate 232 and the bearing on the top of the upper housing 210 and extends to the inner side of the upper housing 210 to connect with the locking block 236. When the upper housing 210 and the lower housing 220 are fixedly installed, the locking block 236 is located in the locking groove 2221. The locking block 236 can limit the wire harness in the locking groove 2221 in a certain direction.

[0046] Working principle: In use, the user inserts multiple wire harnesses from the multi-wire harness power connection 100 into the slots 2221 on the multiple winding posts 222. The user then fixes the upper housing 210 and lower housing 220 together, with the locking block 236 positioned within the slot 2221. When the user needs to store a specific wire harness from the multi-wire harness power connection, the user rotates the rotating component 230 corresponding to the desired harness. Rotating the rotating plate 231 on the rotating component 230 causes the locking block 236 to rotate, which in turn drives the winding posts. When the winding post 222 rotates, it can wind and store the wire harness. When the user wants to unwind the wound wire harness, the user can rotate the rotating plate 231 and pull both ends of the wire harness to unwind the wire harness. This makes it convenient for the user to store the wire harness on the multi-wire harness power connection cable 100 individually or in multiple bundles. It makes it easy for the user to find and separate the required wire harness, and avoids the situation where the wire harnesses on the multi-wire harness power connection cable 100 are tangled and knotted. It also avoids the situation where excessively long wire harnesses are placed randomly and occupy a lot of space.

[0047] The above description is merely a preferred embodiment of this utility model and is not intended to limit the invention. For those skilled in the art, various modifications and variations can be made to this invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this invention should be included within the protection scope of this invention.
