[0004] To achieve the above objectives, this utility model provides the following technical solution: a protective support device for a hot air welding gun, comprising a protective cylinder, a placement groove at one end of the upper surface of the protective cylinder, a protective cavity at the other end of the protective cylinder, a heat insulation plate at the outer end of the protective cylinder corresponding to the protective cavity, a first limiting plate inside the protective cylinder on one side of the placement groove, a second limiting plate inside the protective cylinder on the other side of the placement groove, a protective pad inside the protective cylinder between the first and second limiting plates, and support rods at both ends of the lower surface of the protective cylinder, each support rod having a wear-resistant end.

[0005] Preferably, a first limiting groove is formed upward at the middle position of the first limiting plate, and a second limiting groove is formed upward at the middle position of the second limiting plate. The inner diameter of the first limiting groove is larger than the inner diameter of the second limiting groove, and the first and second limiting grooves are concentrically arranged with the protective cylinder.

[0006] Preferably, the upper surface of the protective cylinder has heat dissipation holes at positions corresponding to the protective cavity, and the interior of the protective cylinder has a heat insulation pad at the lower end of the protective cavity.

[0007] Preferably, the lower end of the protective cylinder is embedded inside the upper end of the two support rods, and the protective cylinder is fixedly connected to the two support rods by welding.

[0008] Preferably, the placement groove and the protective cylinder are integrally processed by a cutting and bending process, and the cross-section of the placement groove has a U-shaped structure.

[0009] Compared with the prior art, the beneficial effects of this utility model are: when using a hot air welding gun to weld a waterproof covering membrane, if the worker needs to perform other operations, the hot air welding gun can be temporarily stored inside the protective support device. The protective support device isolates the high temperature maintained by the hot air gun, preventing the hot air welding gun from being placed on the waterproof covering membrane and reducing the burns caused by the high temperature of the hot air gun to the waterproof covering membrane.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0013] Please see Figure 1-5This utility model provides a protective support device for a hot air welding gun, including a protective cylinder 1. One end of the upper surface of the protective cylinder 1 is provided with a placement groove 2, and the other end of the protective cylinder 1 is provided with a protective cavity 3. A heat insulation plate 4 is provided at the outer end of the protective cylinder 1 corresponding to the protective cavity 3. A first limiting plate 5 is provided inside the protective cylinder 1 on one side of the placement groove 2, and a second limiting plate 6 is provided inside the protective cylinder 1 on the other side of the placement groove 2. A protective pad 7 is provided inside the protective cylinder 1 between the first limiting plate 5 and the second limiting plate 6. Support rods 8 are provided at both ends of the lower surface of the protective cylinder 1, and wear-resistant ends 9 are provided at both ends of the support rods 8.

[0014] In use, a placement groove 2 is opened on the protective cylinder 1. A first limiting plate 5 and a second limiting plate 6 are installed inside the placement groove 2. A protective pad 7 is placed between the first limiting plate 5 and the second limiting plate 6. The hot air welding torch 14, which needs to be temporarily stored, is placed inside the placement groove 2. The first limiting plate 5 and the second limiting plate 6 limit the middle section of the hot air welding torch 14, and the protective pad 7 supports the middle section of the hot air welding torch 14. A protective cavity 3 is set inside the protective cylinder 1 to protect the hot air welding torch 14 from exiting the cylinder. The air end is stored, and a heat insulation plate 4 is set on the outside of the protective cylinder 1 at the position corresponding to the protective cavity 3. The heat insulation plate 4 seals the outer end of the protective cavity 3 to prevent the heat of the hot air welding gun 14 from radiating outward. Support rods 8 are set on both sides of the lower end of the protective cylinder 1, and wear-resistant ends 9 are set at both ends of the support rods 8. The lower end of the protective cylinder 1 is supported by the support rods 8, so that the placement groove 2 of the protective cylinder 1 is always set upward. The wear-resistant ends 9 at both ends of the support rods 8 improve the wear resistance of the support rods 8 when moving.

[0015] The first limiting plate 5 has a first limiting groove 10 opened upward at the middle position, and the second limiting plate 6 has a second limiting groove 11 opened upward at the middle position. The inner diameter of the first limiting groove 10 is larger than the inner diameter of the second limiting groove 11. The first limiting groove 10 and the second limiting groove 11 are concentrically arranged with the protective cylinder 1. The first limiting groove 10 on the first limiting plate 5 and the second limiting groove 11 on the second limiting plate 6 limit the middle section of the hot air welding gun 14, ensuring the firm placement of the hot air welding gun 14 inside the protective cylinder 1.

[0016] The upper surface of the protective cylinder 1 is provided with heat dissipation holes 12 at the position corresponding to the protective cavity 3. The interior of the protective cylinder 1 and the lower end of the protective cavity 3 are provided with heat insulation pads 13. The heat dissipation holes 12 at the upper end of the protective cylinder 1 allow the heat of the hot air welding gun 14 to be dissipated to the outside through the heat dissipation holes 12. The heat insulation pads 13 inside the protective cavity 3 reduce the heat radiation of the hot air welding gun 14 to the protective cylinder 1.

[0017] The lower end of the protective cylinder 1 is embedded inside the upper end of the two support rods 8. The protective cylinder 1 is fixedly connected to the two support rods 8 by welding, which improves the connection strength between the support rods 8 and the protective cylinder 1 and ensures the overall structural strength.

[0018] The placement groove 2 and the protective cylinder 1 are integrally processed by cutting and bending. The cross-section of the placement groove 2 is U-shaped to ensure the overall structural strength.
