Description

Technical Field

[0001] The utility model relates to a protective device, in particular to an adjustable composite air duct temporary protective device. Background Art

[0002] During the installation of composite air ducts, since the main pipe and branch pipe need to be connected by an opening, and the pipe diameter is large, there will be safety hazards without temporary protection. At present, temporary protection of air duct interfaces generally uses protective nets, inclined grids or templates, which are easy to be moved by humans and are not firmly fixed. The gaps in the nets are easy to drop debris and pollute the air ducts. The protective nets are generally located inside the air ducts and have no protective effect on the iron sheets of the air duct interfaces.

[0003] Therefore, the known composite air duct installation method has the above-mentioned inconveniences and problems. Utility Model Content

[0004] The purpose of the utility model is to provide a safe and reliable adjustable composite air duct temporary protection device.

[0005] To achieve the above purpose, the technical solution of the utility model is:

[0006] An adjustable composite air duct temporary protection device comprises a protection plate and a fixing device, and is characterized in that:

[0007] The protective plate is a square plate with U-shaped curling edges around it to prevent scratches on workers; handles are provided on both sides of the protective plate to facilitate transportation, installation and removal; slide grooves are provided 5 cm inward on the four sides of the plate;

[0008] The fixing device comprises a base, a locking ring and a clamping plate. A screw is fixedly arranged in the middle of the base, a clamping plate is arranged at the top of the screw, and a locking ring is movably arranged in the screw.

[0009] Wherein: the base of the fixing device is placed in the slide groove.

[0010] The adjustable composite air duct temporary protection device of the utility model can also be further implemented by adopting the following technical measures.

[0011] The aforementioned adjustable composite air duct temporary protection device, wherein the material of the protection plate is galvanized iron sheet.

[0012] The aforementioned adjustable composite air duct temporary protection device, wherein the size of the protection plate is 100cm*100cm.

[0013] The aforementioned adjustable composite air duct temporary protection device, wherein the end of the clamping plate is arranged in a Y shape.

[0014] After adopting the above technical solution, the adjustable composite air duct temporary protection device of the utility model has the following advantages:

[0015] 1. The protective device has a simple structure and is easy to manufacture;

[0016] 2. Prevent workers from accidentally falling into the air duct; prevent the iron sheet of the air duct interface from being deformed or damaged;

[0017] 3. Simple and convenient operation, easy to load and unload, reusable, and resource-saving. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The present invention is further described below in conjunction with the embodiments and the accompanying drawings.

[0023] Example 1

[0024] The utility model discloses an adjustable composite air duct temporary protection device, which comprises a protection plate and a fixing device.

[0025] Please refer to Figure 1-Figure 4 The utility model discloses an adjustable composite temporary protective device for air ducts. The protective plate is made of galvanized iron sheet 3, the size of which is set to 100cm*100cm, and U-shaped curling edges 1 are arranged around it to prevent workers from being scratched during movement or protection. Handles 5 are arranged on both sides of the protective plate to facilitate transportation, installation and disassembly. A slide groove is arranged 5cm inward on the four sides of the plate surface, and the base 8 of the fixing device is placed in the slide groove 2. The spacing can be set according to the size of the air duct interface by sliding. The locking ring 7 of the screw on the fixing device 4 can be tightened to lock the position of the fixing device and fix the spacing size. The upper splint seam is tightly combined with the air duct interface to ensure that the protective device will not fall off by itself, thereby achieving a protective effect.

[0026] The specific operation steps of the protective device of the utility model embodiment are as follows:

[0027] 1. Verify the size of the air duct interface and determine the size of the protective plate that needs to be adjusted;

[0028] 2. Move the adjustment slider to a suitable position, tighten the locking ring, and fix the slider;

[0029] 3. Grab the handle with both hands, align the splint seam with the interface, and push to clamp it; when proceeding to the next step, grab the handle with both hands and pull it out to remove.

[0030] The utility model has substantial characteristics and significant technical progress. The adjustable composite air duct temporary protection device of the utility model is used during the installation of the project air duct to prevent debris from falling into the air duct and polluting the air duct; it can prevent workers from accidentally falling into the air duct; it can prevent the iron sheet of the air duct interface from being deformed or damaged due to collision; the utility model is simple and convenient to operate, easy to install and remove, reusable, and saves resources.

[0031] The above embodiments are only for the purpose of illustrating the present invention, but not for limiting the present invention. A person skilled in the relevant technical field may make various changes or modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions should also belong to the scope of the present invention and should be defined by the claims.
