[0003] The present application provides another technical solution that can achieve heat shrinking of an insulating sleeve on a copper conductor to improve the heat shrinking efficiency, aiming to provide technicians in this field with a variety of options for solving the problem. Utility Model Content

[0004] In order to be able to heat shrink an insulating sleeve onto a copper conductor to improve the heat shrinking efficiency, the present application provides a heat shrinking device for the insulating sleeve.

[0005] The present application provides a heat shrink device for an insulating sleeve that adopts the following technical solution:

[0006] A heat shrink device for an insulating sleeve comprises a box body, a moving assembly arranged in the box body, a rotating assembly connected to the moving assembly, and a heat shrink assembly arranged on the rotating assembly. The front end of the box body is provided with a feed inlet, and the rear end of the box body is provided with a discharge port located on the same axis as the feed inlet.

[0007] By adopting the above technical solution, the insulating sleeve is put on the copper conductor, and then the insulating sleeve is set between the feed port and the discharge port of the box. Under the driving action of the rotating component, the heat shrink component heat shrinks the circumference of the insulating sleeve, and under the driving action of the moving component, the heat shrink component moves along the length direction of the insulating sleeve and heat shrinks the insulating sleeve, thereby heat shrinking the insulating sleeve on the copper conductor. The whole process can heat shrink the insulating sleeve on the copper conductor to improve the heat shrinkage efficiency.

[0008] Preferably, two groups of clamping parts are provided at the front end of the box body, and the feed port is located between the two groups of clamping parts. Each group of the clamping parts includes a fixed block fixedly connected to the front end of the box body, a threaded rod longitudinally penetrating the fixed block and threadedly connected to the fixed block, and a clamping block rotatably connected to one end of the threaded rod close to the feed port.

[0009] By adopting the above technical solution, the insulating sleeve is installed between the feed port and the discharge port of the box body, and the threaded rod is rotated. Since the threaded rod is threadedly connected to the fixed block, the threaded rod drives the clamping block to move toward the feed port, and the insulating sleeve is clamped between the two clamping blocks.

[0010] Preferably, the moving assembly includes a first driving member installed at the front end of the box and located below the feed port, a screw rod rotatably connected in the box and fixedly connected to the output end of the first driving member, and a moving block threadedly connected to the screw rod.

[0011] By adopting the above technical solution, the first driving member is started, and the first driving member drives the moving block to move in the box body through the screw rod.

[0012] Preferably, the rotating assembly includes a mounting box fixedly connected to the top surface of the moving block, two brackets symmetrically fixed to both ends of the mounting box, a connecting pipe rotatably connected to each bracket, and a transmission component connected to the connecting pipe.

[0013] By adopting the above technical solution, the bracket is used to connect the moving block and the connecting pipe, the connecting pipe is used to connect the heat shrink assembly, and the transmission component is used to drive the two connecting pipes to rotate.

[0014] Preferably, the transmission component includes a second driving member vertically installed in the installation box, a driving bevel gear located on the top surface of the installation box and fixedly connected to the output end of the second driving member, and a driven bevel gear arranged on the connecting pipe and meshing with the driving bevel gear.

[0015] By adopting the above technical solution, the second driving member is started, and the output end of the second driving member drives the active bevel gear to rotate. Since the active bevel gear is meshed with the driven bevel gear, the rotating active bevel gear drives the driven bevel gear to rotate, so that the connecting tube drives the heat shrink assembly to rotate around the insulating sleeve to heat shrink the insulating sleeve.

[0016] Preferably, two heat shrink components are provided on the same connecting tube, the two heat shrink components located on the previous connecting tube are symmetrically arranged in the vertical direction, and the two heat shrink components located on the next connecting tube are symmetrically arranged in the left and right direction.

[0017] By adopting the above technical solution, the heat shrink component can heat shrink the insulating sleeve more evenly.

[0018] Preferably, each group of the heat shrink components includes a fixed box fixedly connected to the end of the connecting tube away from the driven bevel gear, a blower installed on the top of the fixed box, and a heating wire installed on the inner wall of the fixed box.

[0019] By adopting the above technical solution, the hair dryer and the electric heating wire are started to blow hot air out of the lower opening of the fixing box to heat shrink the insulating sleeve.

[0020] Preferably, a handle is fixedly connected to the top surface of the box.

[0021] By adopting the above technical solution, the arrangement of the handle makes it easy to lift the box.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. Put the insulating sleeve on the copper conductor, and then set the insulating sleeve between the feed port and the discharge port of the box. Driven by the rotating component, the heat shrink component shrinks the surrounding side of the insulating sleeve, and driven by the moving component, the heat shrink component moves along the length direction of the insulating sleeve and shrinks the insulating sleeve, so that the insulating sleeve is heat-shrunk on the copper conductor. The whole process can shrink the insulating sleeve on the copper conductor to improve the heat shrinking efficiency;

[0024] 2. Install the insulating sleeve between the feed port and the discharge port of the box, and rotate the threaded rod. Since the threaded rod is threadedly connected to the fixed block, the threaded rod drives the clamping block to move toward the feed port, and the insulating sleeve is clamped between the two clamping blocks;

[0025] 3. Start the hair dryer and the heating wire to blow hot air out of the lower opening of the fixing box to heat shrink the insulating sleeve. BRIEF DESCRIPTION OF THE DRAWINGS

Figure 1 and Figure 2The heat shrink device for the insulating sleeve includes a box body 1, a moving component arranged in the box body 1, a rotating component connected to the moving component, and a heat shrink component arranged on the rotating component. A feed port 11 is provided at the front end of the box body 1, and a discharge port is provided at the rear end of the box body 1, and the feed port 11 and the discharge port are located on the same axis. The insulating sleeve is sleeved on the copper conductor, and then the insulating sleeve is mounted between the feed port 11 and the discharge port of the box body 1. Under the driving action of the rotating component, the heat shrink component shrinks the surrounding side of the insulating sleeve, and under the driving action of the moving component, the heat shrink component moves along the length direction of the insulating sleeve and shrinks the insulating sleeve, thereby shrinking the insulating sleeve on the copper conductor.

[0033] In order to facilitate observation of the situation inside the box 1, the box 1 is a transparent box, and a plurality of evenly distributed air outlets (not shown in the figure) are provided on the rear side of the box 1; in order to facilitate lifting the box 1, a handle 12 is fixedly connected to the top surface of the box 1.

[0034] Reference Figure 1 and Figure 2 In order to clamp the insulating sleeve during the heat shrinking process, the front end of the box body 1 is provided with two sets of clamping parts, and the feed port 11 is located between the two sets of clamping parts. Each set of clamping parts includes a fixing block 13 fixedly connected to the front end of the box body 1, a threaded rod 14 that longitudinally penetrates the fixing block 13 and is threadedly connected to the fixing block 13, and a clamping block 15 that is rotatably connected to one end of the threaded rod 14 near the feed port 11; in order to facilitate the rotation of the threaded rod 14, a rotating disk 141 is fixedly connected to one end of the threaded rod 14 away from the clamping block 15.

[0035] The insulating sleeve is set between the feed port 11 and the discharge port of the box body 1, and the threaded rod 14 is rotated by the turntable 141. Since the threaded rod 14 is threadedly connected to the fixed block 13, the threaded rod 14 drives the clamping block 15 to move toward the feed port 11, and then the insulating sleeve is clamped between the two clamping blocks 15.

[0036] Reference Figure 1 and Figure 3 The moving assembly includes a first driving member 2 installed at the front end of the box body 1 and located below the feed port 11, a screw rod 21 rotatably connected to the box body 1 and fixedly connected to the output end of the first driving member 2, and a moving block 22 threadedly connected to the screw rod 21; in order to limit the movement of the moving block 22, two symmetrically arranged limit plates 23 are fixedly connected to the inner bottom wall of the box, the screw rod 21 and the moving block 22 are both located between the two limit plates 23, the length direction of the limit plate 23 is consistent with the length direction of the screw rod 21, and the moving block 22 slides between the two limit plates 23.

[0037] Reference Figure 1 and Figure 3The rotating assembly includes a mounting box 3 fixedly connected to the top surface of the moving block 22, two brackets 31 symmetrically fixed to the two ends of the mounting box 3, a connecting pipe 32 rotatably connected to each bracket 31, and a transmission component connected to the connecting pipe 32; the transmission component is used to drive the two connecting pipes 32 to rotate, and multiple heat shrink components are provided, and multiple heat shrink components are provided at one end of the two connecting pipes 32 away from each other. The connecting pipe 32 and the feed port 11 are located on the same axis, and the inner diameter of the connecting pipe 32 is larger than the radius of the feed port 11, so that the insulating sleeve is set between the feed port 11 and the discharge port of the box body 1, and there is a gap between the connecting pipe 32 and the insulating sleeve.

[0038] The transmission component includes a second driving member vertically installed in the installation box 3, a driving bevel gear 34 located on the top surface of the installation box 3 and fixedly connected to the output end of the second driving member, and a driven bevel gear 35 arranged on the connecting pipe 32; the number of the driven bevel gears 35 is consistent with the number of the connecting pipes 32 and corresponds one to one, the driven bevel gears 35 are fixedly sleeved on the circumferential side ends of the connecting pipes 32 at corresponding positions, the driving bevel gear 34 is located between the two driven bevel gears 35, and the driving bevel gear 34 is meshed with the driven bevel gear 35.

[0039] Reference Figure 3 and Figure 4 There are two heat shrink components on the same connecting tube 32. The two heat shrink components on the previous connecting tube 32 are symmetrically arranged in the vertical direction, and the two heat shrink components on the next connecting tube 32 are symmetrically arranged in the left and right direction. Thus, the second driving member is started, and the output end of the second driving member drives the active bevel gear 34 to rotate. Since the active bevel gear 34 is meshed with the driven bevel gear 35, the rotating active bevel gear 34 drives the driven bevel gear 35 to rotate, so that the connecting tube 32 drives the heat shrink component to rotate around the insulating sleeve to heat shrink the insulating sleeve.

[0040] Reference Figure 3 and Figure 4 Each set of heat shrink components includes a fixed box 4 fixedly connected to the end of the connecting tube 32 away from the driven bevel gear 35, a blower 41 installed on the top of the fixed box 4, and a heating wire 42 installed on the inner wall of the fixed box 4; the fixed box 4 is a hollow box body 1 with openings at both ends, the blower 41 is installed at the upper opening of the fixed box 4, and the blowing end of the blower 41 faces the heating wire 42. A grille 43 is installed at the lower opening of the fixed box 4; the grille 43 is a stainless steel grille. Thus, the blower 41 and the heating wire 42 are started to blow hot air from the lower opening of the fixed box 4 to heat shrink the insulating sleeve.
