[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] See also Figure 1-5 As shown, a cold shrink cable accessory comprises a cold shrink body 1, wherein the inner cavity of the cold shrink body 1 is provided with a winding ring 2 for enabling the cold shrink body 1 to work, a pulling piece 3 is fixed to the other side of the winding ring 2, a first sealing cover 4 is clamped on one side of the surface of the cold shrink body 1, and a second sealing cover 5 is clamped on the other end of the cold shrink body 1, a plurality of slide grooves 6 are provided on the surface of the winding ring 2, a slider 7 is slidably provided on the surface of the slide groove 6, a slip ring 13 is fixed on the surface of the slider 7, a limiting mechanism 8 for limiting the position of the cable is provided on the surface of the slip ring 13, a mortgage ball 9 in contact with the cable is provided on the surface of the limiting mechanism 8, and a sliding ring 13 is provided on the surface of the slip ring 13. Pull rods 11 are fixed on both sides, and one side of the pull rod 11 passes through the slip ring 13 and is connected to the first sealing cover 4. When the utility model is in use, the shrink part body 1 and the cable can be in a relatively static state with the cooperation of the mortgage ball 9 and the limit mechanism 8, so that it is convenient for the staff to use the pull piece 3, and with the assistance of the slider 7 and the slide groove 6, the position of the slip ring 13 can be changed to further improve the supporting capacity of the slip ring 13 for the shrink part body 1. In addition, with the setting of the first sealing cover 4 and the second sealing cover 5, dust can be prevented from falling into the inner cavity of the shrink part body 1 and affecting the adsorption capacity of the shrink part body 1.
[0021] The limiting mechanism 8 includes a plurality of extension blocks 81 fixed to the surface of the slip ring 13, a slide rod 82 is fixed to the other end of the extension block 81, a slide block 84 is slidably arranged at the other end of the slide rod 82, a spring 83 is sleeved on the surface of the slide rod 82, one end of the spring 83 is fixed to the surface of the extension block 81, and the other end of the spring 83 is fixed to the surface of the slide block 84, and the mortgage ball 9 rotates on one side of the surface of the slide block 84. In this embodiment, through the setting of the extension block 81, the slide rod 82, the spring 83 and the slide block 84, the slide block 84 can slide on the surface of the slide rod 82 under the restriction of the spring 83, thereby achieving the purpose of adjusting the distance from a plurality of mortgage balls 9 to the extension block 81.
[0022] Several extension blocks 81 are equidistantly distributed on the surface of the slip ring 13, and the pull member 3 is inserted between the extension blocks 81 on both sides. In this embodiment, through this arrangement, the several extension blocks 81 and the mortgage ball 9 can produce a relatively balanced clamping force on the cable, and under the setting of the position of the pull member 3 and the extension block 81, the normal pulling of the pull member 3 will not be affected.
[0023] A handle 14 is fixed to the other end of the pull rods 11 on both sides, and the handle 14 and the pull rod 11 form a T shape. In this embodiment, the setting of the handle 14 makes it convenient for the staff to pull the pull rod 11, so that the pull rod 11 can drive the slip ring 13 to move.
[0024] A limiting member 12 is fixed to one end of the pull rod 11 on one side, and the limiting member 12 is arranged to fit the surface of the first sealing cover 4. In this embodiment, the position of the pull rod 11 can be limited by the setting of the limiting member 12, and when the pull rod 11 is used, the staff can remove the limiting member 12.
[0025] There are breakouts 10 on both sides of the surface of the slip ring 13. In this embodiment, through the setting of the breakouts 10, after the slip ring 13 and the limiting mechanism 8 are completely separated from the surface of the cable, the staff can break the slip ring 13 with the help of the breakouts 10, so that the slip ring 13 can be separated from the cable.
[0026] Working principle: When the cable needs to be reinforced with the shrink fitting body 1, the staff can remove the limit piece 12, and remove the first sealing cover 4 and the second sealing cover 5, and then pass the cable through the middle of several mortgage balls 9. With the assistance of several springs 83 and sliding rods 82, several mortgage balls 9 can limit the cable. Under the action of the mortgage balls 9 and the limit mechanism 8, the slip ring 13 and the cable are relatively stable, so that the position of the shrink fitting body 1 and the cable is relatively stable, which makes it convenient for the staff to use the pull piece 3 to pull the winding ring 2, and under the action of the handle 14, the slip ring 13 can drive the mortgage balls 9 to slide on the surface of the cable, thereby changing the position of the slip ring 13. Through the change of the position of the slip ring 13, it is convenient for the staff to further use the winding ring 2. After the handle 14 completely pulls out the slip ring 13, the slip ring 13 is sleeved on the surface of the cable, and the slip ring 13 can be disconnected under the action of the break 10, which makes it convenient for the staff to take out the slip ring 13.
