[0024] 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.

[0025] Embodiment 1

[0026] like Figure 1-5 As shown, a weather-resistant insulating heat shrinkable protective sleeve comprises an insulating heat shrinkable protective sleeve 1, a limiting portion 2, a fixed connecting frame 3, a telescopic plug-in column 5 and an anti-dropping portion 4: the insulating heat shrinkable protective sleeve 1 has an inner groove that is sleeved with the copper wire of the electric wire, wherein the insulating heat shrinkable protective sleeve 1 is coated with a weather-resistant coating on both the inner and outer surfaces to increase the service life of the insulating heat shrinkable protective sleeve 1, while reducing the probability of cracking of the copper wire during use, thereby reducing the safety of the electric copper wire during use; the limiting portion 2 is used to sleeve the insulating heat shrinkable protective sleeve 1, and is used to limit the positional relationship of the insulating heat shrinkable protective sleeve 1; the fixed connecting frame 3 is fixed in the limiting portion 2, and the fixed connecting frame 3 is an "L"-shaped design, and the fixed connecting frame 3 and the limiting part 2 are welded, which are used to fix the position of the fixed connecting frame 3 and provide support points for the anti-falling part 4 and the telescopic plug-in column 5. The end of the fixed connecting frame 3 away from the limiting part 2 is rotatably connected with the telescopic plug-in column 5, and the telescopic plug-in column 5 rotates along its own axis. The rotatable telescopic plug-in column 5 allows the position of the anti-falling part 4 to be changed, which is convenient for the use of the insulating heat shrinkable protective sleeve 1; the anti-falling part 4 is arranged at the end of the fixed connecting frame 3 away from the limiting part 2, and is used to limit the position of the insulating heat shrinkable protective sleeve 1. When the bottom of the anti-falling part 4 abuts the top of the insulating heat shrinkable protective sleeve 1, the insulating heat shrinkable protective sleeve 1 will be limited, thereby reducing the phenomenon of scattering of the insulating heat shrinkable protective sleeve 1.

[0027] The effect achieved by the entire embodiment 1 is that when in use, the insulating heat shrinkable protective sleeve 1 is wrapped around the limiting portion 2. At this time, the bottom of the anti-falling portion 4 is far away from the top of the insulating heat shrinkable protective sleeve 1. When the insulating heat shrinkable protective sleeve 1 is wrapped, the anti-falling portion 4 is rotated. The anti-falling portion 4 will rotate under the action of the telescopic plug-in column 5, and then abut against the top of the insulating heat shrinkable protective sleeve 1, thereby limiting the insulating heat shrinkable protective sleeve 1 and reducing the scattering phenomenon of the insulating heat shrinkable protective sleeve 1.

[0028] Embodiment 2

[0029] like Figure 1-5As shown, a weather-resistant insulating heat shrinkable protective sleeve, the anti-falling part 4 includes a support rod 41 arranged on the fixed connecting frame 3, wherein the support rod 41 is of cylindrical design, and the support rod 41 has a built-in plug-in groove 43 that is plugged into the telescopic plug-in column 5. The built-in plug-in groove 43 and the support rod 41 are of integrated molding design, and are used to be plugged into the telescopic plug-in column 5 when in use, providing a support point and rotation conditions for the anti-falling part 4.

[0030] A limit spring 44 is fixedly provided inside the built-in plug-in slot 43, and the bottom end of the limit spring 44 is fixedly connected to the top end of the telescopic plug-in column 5, and a limit rod 42 is welded to the top end of the support rod 41. The lowest point of the limit rod 42 is coplanar with the highest point of the limit part 2. The limit spring 44 will pull the bottom end of the limit rod 42 to abut against the top end of the built-in ring 21 in a natural state. When it is necessary to pull the insulating heat shrinkable protective sleeve 1 or wrap the insulating heat shrinkable protective sleeve 1 around the limit part 2, the support rod 41 can be rotated. At this time, the support rod 41 will rotate the limit rod 42 under the action of the telescopic plug-in column 5, so that the bottom end of the limit rod 42 is separated from the top end of the limit part 2. When the insulating heat shrinkable protective sleeve 1 is cut, the support rod 41 is rotated in the opposite direction. At this time, the support rod 41 will, under the action of the telescopic plug-in column 5, make the limit rod 42 abut against the top end of the insulating heat shrinkable protective sleeve 1 above the limit part 2 again, thereby limiting the position of the insulating heat shrinkable protective sleeve 1.

[0031] An “L” shape is formed between the limiting rod 42 and the supporting rod 41 , and the limiting rod 42 is pulled by the elastic force of the limiting spring 44 to limit the position of the insulating heat shrinkable protective sleeve 1 .

[0032] The limiting part 2 includes an inner ring 21 located inside the insulating heat shrinkable protective sleeve 1 . The cross section of the inner ring 21 is designed as a circular ring, and the interior of the inner ring 21 is designed as a hollow part. The hollow part is used to place the anti-dropping part 4 .

[0033] The limiting portion 2 also includes a limiting groove 22 which is opened around the surface of the inner ring 21 . The width of the limiting groove 22 is consistent with the width of the insulating heat shrinkable protective sleeve 1 . The limiting groove 22 and the insulating heat shrinkable protective sleeve 1 are intertwined.

[0034] The effect achieved by the entire second embodiment is that when in use, when the limit spring 44 is in a natural state, the bottom end of the limit rod 42 will be pulled to abut against the top end of the built-in ring 21. When it is necessary to pull the insulating heat shrinkable protective sleeve 1 or wrap the insulating heat shrinkable protective sleeve 1 around the limiting portion 2, the support rod 41 can be rotated. At this time, the support rod 41 will rotate the limit rod 42 under the action of the telescopic plug-in column 5, so that the bottom end of the limit rod 42 is separated from the top end of the limiting portion 2. When the insulating heat shrinkable protective sleeve 1 is cut, the support rod 41 is rotated in the opposite direction. At this time, the support rod 41 will, under the action of the telescopic plug-in column 5, the limit rod 42 will again abut against the top end of the insulating heat shrinkable protective sleeve 1 above the limiting portion 2 to limit the position of the insulating heat shrinkable protective sleeve 1.

[0035] Working principle: When using the weather-resistant insulating heat shrinkable protective sleeve, firstly wind the insulating heat shrinkable protective sleeve 1 on the limiting part 2. At this time, the bottom of the anti-falling part 4 is far away from the top of the insulating heat shrinkable protective sleeve 1. When the insulating heat shrinkable protective sleeve 1 is wound, the anti-falling part 4 is rotated. The anti-falling part 4 will rotate under the action of the telescopic plug-in column 5, and then abut against the top of the insulating heat shrinkable protective sleeve 1, so as to limit the insulating heat shrinkable protective sleeve 1 and reduce the scattering phenomenon of the insulating heat shrinkable protective sleeve 1.

[0036] Secondly, when it is necessary to pull the insulating heat shrinkable protective sleeve 1 or wrap the insulating heat shrinkable protective sleeve 1 around the limiting portion 2, the support rod 41 can be rotated. At this time, the support rod 41 will rotate the limiting rod 42 under the action of the telescopic plug-in column 5, so that the bottom end of the limiting rod 42 is separated from the top end of the limiting portion 2. When the insulating heat shrinkable protective sleeve 1 is cut, the support rod 41 is rotated in the opposite direction. At this time, the support rod 41 will, under the action of the telescopic plug-in column 5, make the limiting rod 42 abut against the top end of the insulating heat shrinkable protective sleeve 1 above the limiting portion 2 again, thereby limiting the position of the insulating heat shrinkable protective sleeve 1 and finally completing the work.

Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
