Description

Technical Field

[0001] This utility model relates to the field of power cord connection technology, and in particular to an anti-twist power cord connection device. Background Technology

[0002] Power cords are wires that transmit current. Current is typically transmitted point-to-point. Power cords can be categorized into AC (alternating current) power cords and DC (direct current) power cords. AC power cords usually carry higher voltage alternating current. Because of the higher voltage, these cords require standardized safety certifications before they can be officially manufactured. DC cords, on the other hand, primarily carry lower voltage direct current. Power cords have a wide range of everyday applications, and existing power cord connection devices are often incompatible. Furthermore, when connecting them, there is a possibility of leakage at the connection point, increasing the risk of accidents.

[0003] A power cord connection device is proposed in patent publication number CN215579124U. This patent includes a connection mechanism, a right insulator, a fixing plate, a groove, a left connection mechanism, a fixing ring, a plug, a fixing mechanism, a fixing block, and a sliding groove. By setting the fixing plate and fixing ring into a "T" shape, when connected to the fixing block, the upper ends of the fixing plate and the upper ends of the fixing ring simultaneously engage inside the sliding groove, preventing them from falling off when the fixing block moves. A left inner sheath is provided at the outer end of the left insulator to protect it from contact with the left outer sheath, increasing the thickness of the left insulator in contact with the outside environment, thus better protecting the left insulation. However, this patent still has the following problems:

[0004] When connecting the power cord, it may loosen during use due to vibration or other external forces, resulting in a decrease in the anti-torsion effect. Secondly, once the traditional fixing clip or limiting ring is installed, its position and size are usually fixed and cannot be adjusted according to power cords of different lengths and thicknesses.

[0005] To address the above problems, it is necessary to design an anti-twist power cord connection device to overcome these issues. Utility Model Content

[0006] The main objective of this invention is to provide an anti-twist power cord connection device, which can effectively solve the problems in the background art.

[0026] The connecting limiting assembly 3 includes a first adjusting block 301 disposed at one end inside the slide 2.

Arc-shaped limiting rings 308 are installed on the sides of the two adjusting screws 307 away from the first adjusting block 301 and the second adjusting block 304.

[0027] The first adjusting block 301 and the second adjusting block 304 are slidably connected inside the slide groove 2.

The second adjusting block 304 is fixedly connected to the reinforcing block 305, and the reinforcing block 305 is fixedly connected to the second L-shaped positioning plate 306. The first adjusting block 301 and the second adjusting block 304 are both threadedly fixedly connected to two adjusting screws 307. The two adjusting screws 307 are both threadedly fixedly connected to two arc-shaped limiting rings 308. The two arc-shaped limiting rings 308 are made of polyvinyl chloride and do not contact each other.

[0028] The insulating protective sleeve 1 is installed at an appropriate position on the power cord, usually near the power cord connection point. The first adjusting block 301 and the second adjusting block 304 are respectively inserted into the slide groove 2. Two arc-shaped limiting rings 308 are placed on the first adjusting block 301 and the second adjusting block 304 inside the insulating protective sleeve 1. According to the length of the power cord, the first adjusting block 301 and the second adjusting block 304 are slid to make the arc-shaped limiting rings 308 located where the power cord needs to be fixed. The adjusting screw 307 is rotated to adjust the distance between the two arc-shaped limiting rings 308 to accommodate the thickness of the power cord. The position of the adjusting block is fixed using the first L-shaped positioning plate 302 and the second L-shaped positioning plate 306. The fixing plate 303 and the reinforcing block 305 are installed to increase stability.

[0029] A fixing rod 309 is installed on the top of the fixing plate 303. A positioning block 310 is installed on the top of the fixing rod 309. A positioning rod 311 is installed on one side of the positioning block 310. A first limiting pad 312 is installed at the end of the positioning rod 311 away from the positioning block 310. A lower support ring 314 and an upper support ring 315 are respectively provided at the end of the first limiting pad 312 away from the positioning rod 311. A second limiting pad 313 is provided at the end of the lower support ring 314 and the upper support ring 315 away from the first limiting pad 312. A limiting rod 316 is installed at the end of the lower support ring 314 and the upper support ring 315 away from the second limiting pad 313. A locking seat 317 is installed at the bottom of the limiting rod 316. A locking knob 318 is installed at the top of the limiting rod 316.

[0030] The fixing rod 309 is threadedly fixed to the positioning block 310, the positioning block 310 is threadedly fixed to the positioning rod 311, and the positioning rod 311 is threadedly fixed to the first limiting pad 312; the first limiting pad 312 and the second limiting pad 313 are both threadedly fixed to the lower support ring 314 and the upper support ring 315, the lower support ring 314 and the upper support ring 315 are both threadedly fixed to the limiting rod 316, and the limiting rod 316 is threadedly fixed to the locking seat 317 and the locking knob 318;

[0031] Specifically, the fixing rod 309 is threaded to the positioning block 310, and then the positioning rod 311 is threaded to the fixing rod. The first limiting pad 312 and the second limiting pad 313 are threaded to the lower support ring 314 and the upper support ring 315. The limiting rod 316 is threaded to the lower support ring 314 and the upper support ring 315. The locking seat 317 and the locking knob 318 are threaded to both ends of the limiting rod 316. The locking knob 318 is rotated until the support ring is tightly fixed to the power cord to prevent twisting. The power cord is checked to see if it can move freely within the arc-shaped limiting ring 308 without twisting.

[0032] It should be noted that this utility model is an anti-torsion power cord connection device. In use, the first adjusting block 301 and the second adjusting block 304 move within the slide groove 2, thereby adjusting the position of the two arc-shaped limiting rings 308 within the insulating protective sleeve 1 to accommodate power cords of different lengths. By rotating the adjusting screw 307, the distance between the two arc-shaped limiting rings 308 can be adjusted, thereby adjusting the diameter to accommodate power cords of different thicknesses. The fixing rod 309 is connected to the positioning block 310, while the positioning rod 311 is connected to the first limiting pad 312. The first limiting pad 312 and the second limiting pad 313 are respectively connected to... The lower support ring 314 and the upper support ring 315 are connected to the power cord. These rings limit and protect the power cord from the outside. The support rings move with the movement of the first adjusting block 301, so as to dynamically adapt to the position change of the power cord. The limiting rod 316 passes through the lower support ring 314 and the upper support ring 315 and is locked by the locking seat 317 and the locking knob 318. The rotation of the locking knob will tighten the limiting rod, thereby pressing the support rings to ensure that the power cord is stable within the limiting rings and prevents twisting. When the power cord passes through the arc-shaped limiting ring 308 and is fixed, any force that attempts to twist the power cord will be resisted by the limiting rings and the support rings.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
