Description

Technical Field

[0001] This utility model relates to the field of heating technology, and more specifically, to a public area heating device. Background Technology

[0002] In existing technologies, public area heating equipment suffers from significant problems, including inconvenient installation and disassembly of heating components and difficulty in rotating and adjusting them. Public area heating equipment is a key device for providing a comfortable thermal environment in large public spaces and is widely used in office buildings, shopping malls, stations, stadiums, and other places. The heating components of this type of equipment play a crucial role in the heating system, and their performance and ease of operation directly affect the heating effect, the efficiency of equipment maintenance, and user comfort.

[0003] Firstly, in terms of installation and disassembly, existing heating element designs are often quite complex, making the process inconvenient. Many devices rely on manual or specialized tools for installing and disassembling the heating elements, which not only increases installation and maintenance time but also adds to the operational difficulty. Especially in cases requiring regular cleaning, replacement, or maintenance, operators must stop the machine and spend a significant amount of time manually disassembling and installing.

[0004] Secondly, the adjustment function of the heating components is also insufficient. Most existing heating equipment cannot flexibly adjust the position or angle of the heating components to adapt to different heating needs. In some scenarios, such as places where precise control of heat distribution is required, the adjustment of the heating components is particularly important. However, due to the lack of convenient adjustment mechanisms in the design, the heating components in existing equipment are often fixed in a certain position, resulting in uneven heat distribution and making it difficult to achieve fine adjustment in local or regional areas. Utility Model Content

[0005] (a) Technical problems to be solved In view of the problems existing in the prior art, this utility model provides a public area heating device to solve the technical problems mentioned in the background art, such as the inconvenience of installing and disassembling the heating components and the difficulty in rotating and adjusting the heating components.

[0006] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a public area heating device, including a vehicle platform, a heating component, a rotation adjustment mechanism, an installation and locking mechanism, and a locking auxiliary mechanism. The rotation adjustment mechanism includes a rail base and a rotating disk. The rail base is installed at the top end of the vehicle platform, and a rotating block is installed at the bottom end of the rotating disk, with the rotating block rotatably mounted on the rail base. A support rod is rotatably mounted on the vehicle platform, with one end of the support rod connected to the rotating disk. A locking plate is installed on the side of the support rod. The installation and locking mechanism includes a locking tube and a locking rod. An arcuate groove plate is rotatably embedded in the side wall of the locking tube. A bottom fixing plate is installed at the bottom end of the outer wall of the locking tube, and a centripetal rail is installed on the bottom fixing plate. A locking block is slidably mounted on the centripetal rail and is slidably connected to the arcuate groove plate. A ratchet ring is rotatably connected to the outer wall of the locking tube, and the ratchet is connected to the arcuate groove plate. A longitudinal sliding ring is slidably mounted on the outer wall of the locking tube, with a spring plate installed at the outer end of the longitudinal sliding ring.

[0007] The present invention is further configured such that the snap-fit ​​auxiliary mechanism includes an outer rotating ring and a fixing block. Multiple sets of fixing blocks are fixedly installed on the outer wall of the snap-fit ​​tube. A tightening block is slidably installed at the top end of the outer rotating ring, and a tightening spring is installed between adjacent tightening blocks. The adjacent tightening blocks sequentially fit the fixing blocks, so that the outer rotating ring rotates stably on the outer wall of the snap-fit ​​tube. The outer rotating ring and the longitudinal moving ring are threadedly connected.

[0008] The present invention is further configured such that bottom wheels are installed around the bottom of the vehicle platform, and a push handle is installed on one end face of the vehicle platform. The bottom wheels are installed around the bottom of the vehicle platform to facilitate the movement of the equipment and meet the needs of flexible deployment in public areas.

[0009] The present invention is further configured such that the rail base is provided with locking holes, and multiple sets of locking holes are provided. A locking bolt is installed on the locking plate, and the locking bolt is connected with the locking holes to fix the locking plate. The locking bolt is installed on the locking plate and is connected with multiple sets of locking holes on the rail base to achieve fixation at different angle positions and ensure the stability of the heating direction.

[0010] The present invention is further provided that an installation plate is installed around the bottom end of the heating component, and a bottom fixing plate is fixedly installed on the installation plate. The installation plate facilitates the installation of the heating component.

[0011] The present invention is further configured such that a limiting block is installed at one end of the locking rod, and the other end of the locking rod passes through the rotating disk and the mounting plate to engage with the locking tube.

[0012] The present invention is further configured such that a push block is installed at the top end of the card block, and the push block is slidably pushed against the arc groove plate. The rotation of the arc groove plate causes the card block to be embedded into or away from the carding rod. The push block is installed at the top end of the card block and is slidably pushed against the arc groove plate to provide precise pushing force transmission for the movement of the card block.

[0013] The present invention is further configured such that a shrinkage rail is installed on one end face of the outer rotating ring, and a tightening block is configured to slide radially on the shrinkage rail.

[0014] (III) Beneficial Effects Compared with the prior art, this utility model provides a public area heating device with the following advantages: This utility model is equipped with a rotation adjustment mechanism. The rail base is installed on the top end of the vehicle plate, and the rotating disk is mounted on the rail base through a rotating block. The support rod connects to the rotating disk to realize angle transmission, realizing multi-angle rotation adjustment of the heating component to meet the heating needs in different directions. The locking plate cooperates with multiple sets of locking holes on the rail base to achieve precise fixation at different angle positions through locking bolts, ensuring stable heating direction. This solves the problem of the single direction of traditional fixed heating equipment and improves the adaptability and flexibility of the equipment.

[0015] This utility model features an installation locking mechanism. The locking tube is embedded with an arc-shaped groove plate, and a centripetal rail and locking block are installed on the bottom fixed plate. The locking block is slidably connected to the arc-shaped groove plate through a push block. The rotation of the arc-shaped groove plate drives the locking block to move radially along the centripetal rail, thereby locking or releasing the locking rod. This provides a quick modular installation and disassembly function for the heating component, solving the problems of complex connection methods and difficult replacement in traditional methods. The bottom fixed plate is fixedly installed on the heating component mounting plate, realizing a standardized connection interface and improving the modularity and maintenance convenience of the equipment.

[0016] This utility model features a locking auxiliary mechanism. A ratchet connects to a curved groove plate, and a spring-loaded tab on the longitudinal moving ring contacts the ratchet ring to prevent the curved groove plate from rotating in the opposite direction. The outer rotating ring is connected to the longitudinal moving ring via threads. Multiple sets of fixing blocks, in conjunction with tightening blocks and a shrinking rail, ensure stable rotation of the outer rotating ring on the locking tube. Tightening springs are installed between the tightening blocks, which are sequentially fitted onto the fixing blocks to form a reliable ring lock, providing double safety locking protection. This prevents loosening of the connection due to vibration, temperature changes, or other factors during heating, ensuring the safety and stability of the equipment operation and avoiding safety hazards caused by accidental detachment of the heating components.
