Description

Technical Field

[0001] This utility model relates to the field of heat shrink tubing packaging technology, and more specifically, it relates to a wire harness heat shrink tubing packaging device. Background Technology

[0002] Heat shrink tubing is a type of heat shrink sleeve made of polyolefin material. It is commonly used to wrap and limit various wire harnesses, solder joints, and inductors, and also serves as insulation protection. The shrinking temperature range of heat shrink tubing is 84℃~120℃, and it has the special function of shrinking when heated; it can shrink when heated to above 98℃.

[0003] When sealing wire harness heat shrink tubing, people usually use a hot air gun to blow hot air onto the outside of the heat shrink tubing. The heat shrink tubing is then sealed to the outside of the wire harness. However, when using a hot air gun to blow hot air onto the heat shrink tubing, hot air can only be blown from one side of the heat shrink tubing. It is not convenient to blow hot air evenly around the heat shrink tubing, resulting in poor heating uniformity of the heat shrink tubing and poor sealing effect of the wire harness heat shrink tubing.

Hot air blown out through multiple first and second air nozzles is evenly blown onto the outside of the heat shrink tube, which facilitates uniform heating of the heat shrink tube, causing it to shrink evenly and ensuring the sealing effect of the heat shrink tube.

[0008] The present invention is further provided in that two sliding grooves are provided on the inner side wall of the connecting pipe at the position corresponding to the hot air gun, and clamping seats are slidably arranged inside the two sliding grooves. A screw is threadedly connected to the connecting pipe at the position corresponding to the two clamping seats, and the side end of the screw is rotatably connected to the side end of the clamping seat, so as to facilitate the connection pipe being securely installed on the hot air gun.

[0009] The present invention is further provided that an anti-slip pad is fixedly connected to the side end of the clamping seat to increase the friction of the clamping seat surface.

[0010] The present invention is further provided that a throttle handle is fixedly connected to the side end of the screw to facilitate the rotation of the screw.

[0013] The present invention is further provided that a handle is fixedly connected to the top end of the jacking pipe, and a heat insulation sleeve is provided on the outside of the handle to facilitate pulling the jacking pipe to move.

[0014] The present invention is further configured such that a baffle plate is fixedly connected inside the connecting pipe at the position corresponding to the L-shaped pipe, and a gap is left between the top of the baffle plate and the connecting pipe to facilitate the hot air blown out from inside the hot air gun to be evenly blown into the top pipe and the interior of the heating pipe.

[0015] The present invention is further configured such that a limiting groove is provided on the connecting pipe, and a limiting block adapted to the limiting groove is fixedly connected to the hot air gun, which plays a limiting role in the connecting pipe.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, the present invention provides a wire harness heat shrink tubing packaging device, which has the following beneficial effects:

[0018] 1. The heating tube is fitted over the wire harness and heat shrink tubing through the notch. The compression spring pushes the fixing block and the top tube to move, so that the top tube moves to the position of the notch, and the heating tube and the top tube are fitted over the wire harness and heat shrink tubing. The hot air is blown into the interior of the heating tube and the top tube by the hot air gun. The hot air is blown evenly to the outside of the heat shrink tubing through multiple first air outlets and multiple second air outlets, so as to facilitate uniform heating of the heat shrink tubing, so that the heat shrink tubing shrinks evenly and ensures the sealing effect of the heat shrink tubing.

[0019] 2. Insert the connecting tube into the outside of the hot air gun. By setting up a clamping seat and screw, the clamping seat clamps and fixes the hot air gun, which makes it easy to securely connect the connecting tube to the hot air gun. Separating the clamping seat from the hot air gun makes it easy to remove the connecting tube from the hot air gun, thus facilitating its assembly and disassembly.

[0020] 3. The ventilation pipe and L-shaped pipe slide together. Pulling the handle moves the jacking pipe, causing the compression spring to contract. This makes it easy to pull the jacking pipe to one side of the heating pipe. It also makes it easy to put the heating pipe over the wire harness and heat shrink tubing through the notch. Releasing the handle allows the compression spring to push the fixing block and jacking pipe to move, moving the jacking machine to the position of the notch. Its operation is simple and convenient, improving its practicality. Attached Figure Description

[0030] Please see Figures 1-5 A wire harness heat shrink tubing packaging device includes a hot air gun 1. A connecting tube 2 is sleeved on the outside of the air outlet end of the hot air gun 1. A limiting groove 25 is provided on the connecting tube 2. A limiting block 26 adapted to the limiting groove 25 is fixedly connected to the hot air gun 1 to limit the connecting tube 2. A heating tube 3 is connected to the side end of the connecting tube 2. A plurality of first air outlets 4 are evenly arranged on the inner side wall of the heating tube 3. A notch 5 is provided at the top end of the heating tube 3. An L-shaped tube 6 is connected to the connecting tube 2. A baffle plate 24 is fixedly connected to the inside of the connecting tube 2 at a position corresponding to the L-shaped tube 6. The size of the baffle plate 24 is set according to the actual use requirements. A gap is left between the top end of the baffle plate 24 and the connecting tube 2 to facilitate the hot air blown from the inside of the hot air gun 1 to be evenly blown to the top tube 8 and the interior of the heating tube 3. A ventilation tube 7 is slidably arranged inside the L-shaped tube 6. One end is provided with a jacking pipe 8 that is compatible with the notch 5. A handle 22 is fixedly connected to the top of the jacking pipe 8. A heat insulation sleeve 23 is fitted on the outside of the handle 22 to facilitate the movement of the jacking pipe 8. Multiple second air outlets 9 are provided on the jacking pipe 8. Two fixing blocks 10 are fixedly connected to the jacking pipe 8. A slide rod 11 is fixedly connected to each of the two fixing blocks 10. Two fixing plates 12 are fixedly connected to the connecting pipe 2. The two fixing plates 12 are slidably engaged with the two slide rods 11 respectively. A compression spring 13 is provided between the fixing plate 12 and the corresponding fixing block 10. The compression spring 13 is fitted on the outside of the slide rod 11. A first limiting plate 20 is connected to the side end of the slide rod 11 by a screw 18 to limit the jacking pipe 8. A second limiting plate 21 is connected to the side end of the heating pipe 3 at the position corresponding to the jacking pipe 8 by a screw 18 to limit the slide rod 11.

[0031] Specifically, the heating tube 3 is fitted onto the outside of the wire harness and heat shrink tubing through the notch 5. The compression spring 13 pushes the fixing block 10 and the top tube 8 to move, so that the top tube 8 moves to the position of the notch 5, allowing the heating tube 3 and the top tube 8 to fit onto the outside of the wire harness and heat shrink tubing. The hot air gun 1 blows hot air into the inside of the heating tube 3 and the top tube 8. The hot air is evenly blown onto the outside of the heat shrink tubing through multiple first air nozzles 4 and multiple second air nozzles 9, which facilitates uniform heating of the heat shrink tubing and uniform shrinkage, ensuring the sealing effect of the heat shrink tubing. The ventilation tube 7 slides with the L-shaped tube 6, and the top tube 8 is moved by the pull handle 22, causing the compression spring 13 to contract, making it easy to pull the top tube 8 to one side of the heating tube 3, so that the heating tube 3 can be fitted onto the outside of the wire harness and heat shrink tubing through the notch 5. Releasing the pull handle 22 allows the compression spring 13 to push the fixing block 10 and the top tube 8 to move, so that the top tube 8 moves to the position of the notch 5. The operation is simple and convenient, improving its practicality.

[0032] Please see Figures 2-4 Two grooves 14 are provided on the inner wall of the connecting pipe 2 at positions corresponding to the hot air gun 1. Clamping seats 15 are slidably arranged inside the two grooves 14. Screws 16 are threadedly connected to the connecting pipe 2 at positions corresponding to the two clamping seats 15. The side end of the screw 16 is rotatably connected to the side end of the clamping seat 15. An anti-slip pad 17 is fixedly connected to the side end of the clamping seat 15 to increase the friction of the surface of the clamping seat 15. A throttle 19 is fixedly connected to the side end of the screw 16 to facilitate the rotation of the screw 16.

[0033] Specifically, the connecting pipe 2 is inserted into the outside of the hot air gun 1. By setting up structures such as the clamping seat 15 and the screw 16, the clamping seat 15 clamps and fixes the hot air gun 1, so that the connecting pipe 2 is firmly connected to the hot air gun 1. The clamping seat 15 is separated from the hot air gun 1, so that the connecting pipe 2 can be removed from the hot air gun 1, thus facilitating its assembly and disassembly.

[0034] In conclusion,

[0035] When sealing the heat shrink tubing, the top tube 8 is moved by pulling the handle 22, causing the compression spring 13 to contract and pull the top tube 8 to one side of the heating tube 3. Then, the heating tube 3 is fitted over the wire harness and the heat shrink tubing to be sealed through the notch 5. Then, the handle 22 is released, and the compression spring 13 facilitates the movement of the fixing block 10 and the top tube 8, so that the side end of the top tube 8 contacts the side end of the second limiting plate 21. At this time, the top tube 8 moves to the position of the notch 5, so that the wire harness and the heat shrink tubing are located in the middle of the circular tube formed by the heating tube 3 and the top tube 8. Then, the hot air gun 1 is turned on, and hot air of a certain temperature is blown through the connecting pipe 2, the L-shaped pipe 6 and the ventilation pipe 7 into the interior of the heating tube 3 and the top tube 8. The hot air is blown out through multiple first air outlets 4 and multiple second air outlets 9, and is evenly blown to the outside of the heat shrink tubing. The heat shrink tubing shrinks due to heat, so that the heat shrink tubing is evenly sealed to the outside of the wire harness.
