Description

Technical Field

[0001] This utility model relates to the field of hot air blower technology, specifically to a lightweight hot air blower frame. Background Technology

[0002] Traditional hot air blower frames are mostly made of metal or heavy plastic. While structurally stable, they suffer from being heavy and lacking portability, especially in outdoor operations or scenarios requiring frequent movement, increasing the operational burden. Furthermore, some lightweight designs, due to insufficient material strength or simple structure, are prone to vibration instability and deformation over long-term use, making it difficult to balance portability and reliability. In addition, existing frames are mostly fixed structures, cumbersome to disassemble, and inconvenient for quick storage or component replacement. With the widespread application of hot air blowers in industrial, agricultural, and emergency fields, the market urgently needs a lightweight, high-strength, easy-to-assemble, and stable frame solution to improve equipment mobility and efficiency.

Rollers are connected to both ends of the axle, and two feet are provided on the axle to support the hot air blower frame. The mounting bracket includes a push rod and limiting rods at both ends of the push rod. The limiting rods have sliding holes and bolt mounting holes. The feet have a row of screw holes, and the limiting screws pass through the sliding holes and are screwed into the screw holes; the fastening bolts are screwed into the bolt mounting holes. The advantages of this invention are: the feet combined with the rollers allow for easy pushing or fixing, simplifying the structure and making it lightweight and compact; the height of the mounting bracket can be adjusted, making it more convenient for different users to push the hot air blower; the position of the hot air blower can be adjusted by adjusting the fastening bolts or the mounting bracket, allowing it to generate heat in a more suitable location.

[0004] Although the equipment described in the aforementioned literature can be equipped with a hot air blower, its structure is relatively simple and its adjustment flexibility for the support legs is insufficient, which limits its ease of use. Furthermore, the frame is not convenient enough for the hot air blower to be disassembled and assembled, reducing the practical value of the equipment. Utility Model Content

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This invention provides a lightweight hot air blower frame. The device is equipped with a support system, which improves flexibility, stability, and adaptability to various environments, addressing the pain points of traditional hot air blowers in complex environments. It also offers advantages such as safety, high efficiency, and ease of maintenance. The support leg height can be adjusted according to ground flatness or operational needs, ensuring the hot air blower remains level even on uneven or tilted surfaces, preventing vibration, noise, or safety hazards caused by equipment tilting. The support legs can rotate at multiple angles and independently adjust the tilt angle, flexibly adapting to complex terrains such as slopes and potholes, enhancing the device's fit with the ground. To prevent tipping, the telescopic function allows for height adjustment of the hot air blower, facilitating connection with pipes, vents, or other equipment and improving system integration efficiency.

The second connecting frame allows the casters to move, making it more flexible in use.

[0019] This utility model provides a lightweight hot air blower frame. The device is equipped with a connecting device that makes the hot air blower easier to assemble and disassemble. The buckle provides lateral locking, and the shock-absorbing component provides vertical buffering, forming a three-dimensional fixing system of "vibration resistance + anti-detachment" to ensure long-term stable operation of the equipment. The buckle connection avoids thread wear caused by frequent tightening of bolts, and the shock-absorbing component reduces metal fatigue, thus extending the service life of the frame and the hot air blower. The buffer design also prevents the hot air blower from loosening or breaking parts due to resonance. Quick assembly and disassembly facilitate regular inspection or replacement of the shock-absorbing component, reducing maintenance complexity and downtime frequency. When vibration occurs, the first spring provides a certain buffering effect when the buffer is pressed down, and the second spring buffers the impact force of the vibration. A damper is set to absorb the vibration of the second spring's rebound, keeping the equipment stable. In addition, pulling the handle causes the slide bar to slide, and after pulling the locking rod out of the second locking plate, the hot air blower can be placed in the installation area. Releasing the handle allows the third spring to automatically reset the locking rod, allowing it to pass through the second locking plate and be placed into the corresponding slot of the fixing seat, thereby locking and fixing it. Disassembly is the same, making the operation very convenient. Attached Figure Description
