[0026] Please refer to Figures 1-4 ;

[0027] Embodiment 1:

[0028] A hot air gun protective cover 1 includes a protective cover 1 and a mounting box 2. The protective cover 1 and the mounting box 2 can be integrally formed or can be detachably connected. In this embodiment, the protective cover 1 and the mounting box 2 are detachably connected. The specific connection manner of the detachable connection between the protective cover 1 and the mounting box 2 in this embodiment is not limited, and can be clamping connection, threaded connection, and snap connection. In this embodiment, taking the detachable connection between the protective cover 1 and the mounting box 2 as an example for illustration, the side of the protective cover 1 away from the mounting box 2 is the inner cavity surface. By using the inner cavity surface, when the blower blows away iron filings, it can better protect the operator from being touched by iron filings or other substances. A circle of conical protrusions 3 is provided on the side of the mounting box 2 facing the protective cover 1. Correspondingly, a circle of clamping grooves 4 is opened on the protective cover 1. The conical protrusions 3 are clamped with the clamping grooves 4. In addition, the protective cover is also provided with clamping holes 5. The clamping holes 5 are located on one side of the clamping grooves 4, and when the clamping grooves 4 are clamped with the conical protrusions 3, the clamping holes 5 are clamped with the extended part of the bottom plate 6 of the mounting box 2; The protective cover 1 is provided with a first clamping hole 7, and the mounting box 2 is provided with a second clamping hole 8 at the same height as the first clamping hole 7 of the protective cover 1. The first clamping hole 7 is communicated with the second clamping hole 8. A sliding assembly is slidably installed in the mounting box 2. The sliding direction of the sliding assembly relative to the mounting box 2 is the vertical direction. The upper surface of the sliding assembly and the inner hole wall of the first clamping hole 7 of the protective cover 1 form a gun fixing hole 9 with a variable space size. The gun fixing hole 9 is a rhombic hole. The hot air gun sequentially passes through the second clamping hole 8, the gun fixing hole 9, and the first clamping hole 7 and is clamped with the protective cover 1, that is, the hot air gun is clamped with the gun fixing hole 9.

[0029] Specifically, this embodiment is applied to the protection of a heat gun, that is, this protection device is combined with the heat gun, so that the substances sprayed by the heat gun can be blocked by the protective cover 1, protecting the user from being injured by the splashed substances. When assembling the heat gun, the operator should first adjust the size of the gun-fixing hole 9 by sliding the sliding component, and then align the heat gun with the second card hole 8. The operator operates the heat gun to pass through the second card hole, the gun-fixing hole 9 and the first card hole 7 in sequence. The operator adjusts the size of the gun-fixing hole 9 again, and clamps the heat gun on the hole wall of the gun-fixing hole 9, completing the assembly of the protection device and the heat gun in this embodiment.

[0030] The sliding component in this embodiment includes a sliding member 10 and a spring 11. The length direction of the spring 11 is the same as the length direction of the installation box 2. The sliding member 10 includes a top plate 101 and two side plates 102. The length directions of the two side plates 102 are the same as the length direction of the installation box 2. The two side plates 102 are respectively fixedly connected to both ends of the top plate 101. One end of the spring 11 is fixedly connected to the middle of the bottom plate 6 of the installation box 2, and the other end of the spring 11 is fixedly connected to the lower surface of the top plate 101 of the sliding member 10. The installation box 2 is also provided with an adjustment component for adjusting the compression of the spring 11, and further adjusting the space size of the gun-fixing hole 9. In this embodiment, the adjustment component includes a pull block, and the pull block is a circular hanging ring 12. A notch 14 is opened in the direction of the circular hanging ring 12 facing the installation box 2. Two straight rods 13 extend from the notch 14 of the circular hanging ring 12. Two adjustment holes 15 are opened at the bottom of the installation box 2. The two straight rods 13 of the circular hanging ring 12 respectively pass through the two adjustment holes 15 and are fixedly connected or integrally formed with the bottom ends of the two straight plates.

[0031] Specifically, when the operator needs to enlarge the area of the gun-fixing hole 9, only need to vertically pull down the circular hanging ring 12. The circular hanging ring 12 will drive the side plates 102 of the sliding member 10 to move vertically downward. The vertical downward movement of the side plates 102 of the sliding member 10 will drive the straight plate of the sliding member 10 to move downward. The vertical downward movement of the straight plate of the sliding member 10 makes the aperture of the gun-fixing hole 9 increase, facilitating the heat gun to pass through. After the heat gun passes through the gun-fixing hole 9, the operator can loosen the circular hanging ring 12. Under the action of the spring 11 restoring deformation, the straight plate of the sliding member 10 will move upward, coming into contact with the heat gun and clamping the heat gun between the hole wall of the first card hole 7 and the upper surface of the top plate 101. At the same time, the spring 11 still has a deformation amount, that is, the spring 11 provides a force for the sliding member 10 to continue moving upward, thus clamping the heat gun. The structure is simple and highly reliable.

[0032] To improve the convenience of placing the protective cover 1, one side edge of the protective cover 1 is set as a straight edge 17, and a hanging hole 16 is provided on the other side edge of the protective cover 1, so that the operator can hang the protective cover 1 on the wall when stopping using the protective cover 1.

[0033] Embodiment 2:

[0034] Most of the structures of this embodiment are the same as those of Embodiment 1.

[0035] The difference between the structure of this embodiment and that of Embodiment 1 is as follows:

[0036] The adjusting component of this embodiment includes an adjusting block (not shown in the figure). The shape of the adjusting block is not limited in this embodiment. A clearance hole (not shown in the figure) is provided on the side plate 102 of the mounting box 2. The length direction of the clearance hole is consistent with the sliding direction of the sliding member 10. The adjusting block passes through the clearance hole and is fixedly connected to the side plate 102 of the sliding member 10. The hole wall of the clearance hole is slidably connected to the adjusting block. The width of the clearance hole should be greater than the width of the adjusting block to reduce the friction between the adjusting block and the hole wall of the clearance hole. The position of the sliding member 10 can be changed by adjusting the position of the adjusting block, so as to change the aperture of the gun-fixing hole 9.

[0037] Specifically, when an operator assembles the air gun and the protective cover 1, the position of the adjusting block can be first toggled downward, so that the adjusting block slides vertically downward relative to the clearance hole, and then drives the side plate 102 of the sliding member 10 to move downward, and further drives the top plate 101 of the sliding member 10 to compress the spring 11 downward, thereby expanding the aperture of the gun-fixing hole 9, so that the air gun can pass through the gun-fixing hole 9; after the air gun is installed at the designated position of the protective cover 1, the operator can release the adjusting block. Under the action of the spring 11, the straight plate of the sliding member 10 will move upward, so as to contact the air gun and clamp the air gun between the hole wall of the first clamping hole 7 and the upper surface of the top plate 101. At the same time, the spring 11 still has a deformation amount, that is, the spring 11 provides a force for the sliding member 10 to continue to move upward, so as to clamp the air gun. The structure is simple and highly reliable.
