Description

Technical Field

[0001] This utility model relates to the field of heater mesh frames, and more particularly to a foldable protective mesh frame for heaters. Background Technology

[0002] As a common indoor heating device, heaters transfer heat to the indoor environment through radiation or convection to raise the temperature and meet people's heating needs in the cold season. Because the heating element of a heater is at a high temperature when it is working, it is usually equipped with an external protective mesh to prevent people from accidentally touching foreign objects and causing burns or fire risks.

[0003] However, existing protective net frames are mostly fixed structures, making them difficult to fold or store. This results in them occupying a large amount of space when not in use, which is not conducive to transportation and storage. At the same time, the installation and disassembly process of protective net frames is cumbersome and the operation steps are complicated, resulting in a poor user experience. Furthermore, traditional protective net frames are mostly planar structures. When the heater is accidentally tipped over, the impact force can be directly transmitted to the heater body through the protective net frame, causing stress concentration on internal components, which can lead to structural damage or loosening of connecting parts, affecting the long-term stability and safety of the equipment.

[0004] Therefore, existing technologies have shortcomings and need to be improved. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a foldable protective mesh frame for a heater that is easy to use, convenient to assemble and disassemble, and has a good protective effect.

[0006] To achieve this objective, the present invention adopts the following technical solution: a foldable protective mesh frame for a heater, comprising a first frame, a second frame, and a heater body;

[0007] The first frame has a rotating hole at one end, and the second frame has a connecting rod at one end. The connecting rod is sleeved in the rotating hole so that the second frame can be folded or unfolded relative to the first frame.

[0008] The end of the second frame away from the connecting rod is provided with a vertically downward snap-fit ​​rod, and the bottom end of the heater body is provided with an embedding hole for positioning and snapping with the snap-fit ​​rod;

[0009] The first frame has a positioning ring at the end away from the rotary hole, and the top of the heater body has a threaded hole. The positioning ring is used to allow the locking bolt to pass through it and be threadedly connected to the threaded hole to fix the first frame to the heater body.

[0010] Using the above technical solution, in the foldable protective mesh frame of the heater, the second frame has a closed structure;

[0011] The second frame has a crossbar section at the side end near the snap-fit ​​rod, which is used to limit the contact with the wall surface of the heater body.

[0012] Using the above technical solution, in the foldable protective mesh frame of the heater, the first frame is provided with a first horizontal section, a second horizontal section and a first arc-shaped section on both sides;

[0013] The first horizontal segment and the second horizontal segment are connected by the first arc-shaped segment, and the positioning ring is located at the end of the second horizontal segment.

[0014] Using the above technical solution, in the foldable protective mesh frame of the heater, the second frame is provided with diagonal rod sections, a third horizontal section and a second arc-shaped section on both sides;

[0015] The diagonal section and the third horizontal section are connected by the second arc-shaped section, and the snap-fit ​​rod is located at the end of the third horizontal section.

[0016] Using the above technical solution, in the foldable protective mesh frame of the heater, when the first frame and the second frame are in the unfolded state and connected to the heater body, the inclined rod segment and the first horizontal segment form an angle of 20-40°.

[0017] Using the above technical solution, in the foldable protective mesh frame of the heater, the first frame is provided with a protective mesh structure.

[0018] Using the above technical solution, in the foldable protective mesh frame of the heater, both the first frame and the second frame are made of metal.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] In this utility model, the first frame and the second frame of the foldable protective mesh frame are connected by a rotatable connection, allowing the second frame to be folded or unfolded relative to the first frame. During installation, the locking rod of the second frame can be inserted into the embedding hole at the bottom of the heater body to achieve lower positioning and support, and then the upper part is locked by the positioning ring at the tail end of the first frame in conjunction with the threaded hole, thus forming a stable connection. The entire installation process is smooth, easy to operate, and the structure is stable. When not in use, the protective mesh frame can be folded and retracted, thereby reducing the storage space occupied and facilitating the transportation or storage of the heater.

Obviously, the embodiments described below 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 skilled in the art without creative effort are within the scope of protection of the present utility model.

It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component centrally located at the same time.

[0031] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0032] like Figures 1 to 6 As shown, this utility model embodiment provides a foldable protective mesh frame for a heater, including a first frame 1, a second frame 2, and a heater body 3. One end of the first frame 1 is provided with a rotating hole 11, and one end of the second frame 2 is provided with a connecting rod 21. The connecting rod 21 is sleeved in the rotating hole 11 so that the second frame 2 can be folded or unfolded relative to the first frame 1. The end of the second frame 2 away from the connecting rod 21 is provided with a vertically downward snap-fit ​​rod 22. The bottom end of the heater body 3 is provided with an embedding hole 31 that is positioned and snapped with the snap-fit ​​rod 22. The end of the first frame 1 away from the rotating hole 11 is provided with a positioning ring 12. The top end of the heater body 3 is provided with a threaded hole 32. The positioning ring 12 is used to allow a locking bolt to pass through it and be threadedly connected to the threaded hole 32 to fix the first frame 1 to the heater body 3. During installation, the second frame 2 can be unfolded from its folded state to form a certain angle with the first frame 1. At this time, the locking rod 22 of the second frame 2 can be aligned and inserted into the embedding hole 31 at the bottom of the heater body 3 to achieve initial positioning and support. After the locking is completed, the positioning ring 12 of the first frame 1 is aligned with the threaded hole 32 at the top of the heater body 3, and the locking bolt is passed through the positioning ring 12 and screwed into the threaded hole 32 to firmly lock the first frame 1 to the upper part of the heater body 3. This achieves the fixed installation of the protective mesh frame. This locking and then locking method not only simplifies the installation steps and reduces the difficulty of operation, but also enhances the stability of the protective mesh frame installation structure. In addition, when not in use, the protective mesh frame can be easily disassembled and folded to reduce storage space and facilitate the transportation or storage of the heater.

[0033] like Figure 5As shown, the second frame 2 is further enclosed, and a crossbar section 23 is provided on the side end of the second frame 2 near the locking rod 22. The crossbar section 23 is used to limit and abut against the wall surface of the heater body 3. When the installer unfolds the second frame 2 from the folded state to a predetermined angle and inserts the locking rod 22 into the embedding hole 31 at the bottom of the heater body 3 for initial positioning, the crossbar section 23 can abut against the outer wall surface of the heater body 3, thereby playing a limiting role and preventing the second frame 2 from continuing to flip outward or swing beyond the angle, thus enhancing the stability of the structure.

[0034] like Figure 4 and Figure 5 As shown, the first frame 1 further comprises a first horizontal segment 101, a second horizontal segment 102, and a first arc-shaped segment 103 on both sides. The first horizontal segment 101 and the second horizontal segment 102 are connected by the first arc-shaped segment 103, and the positioning ring 12 is disposed at the tail of the second horizontal segment 102.

[0035] like Figure 4 and Figure 5 As shown, the second frame 2 is further provided with a diagonal rod section 201, a third horizontal section 202 and a second arc-shaped section 203 on both sides. The diagonal rod section 201 and the third horizontal section 202 are connected by the second arc-shaped section 203. The snap-fit ​​rod 22 is located at the tail of the third horizontal section 202.

[0036] like Figure 4 As shown, further, when the first frame 1 and the second frame 2 are in the unfolded state and connected to the heater body 3, the inclined rod segment 201 and the first horizontal segment 101 form an angle α, which is 20-40°. In this embodiment, the angle α is 30°. This setting allows the protective mesh frame to present a forward-leaning and outward-spreading three-dimensional structure, forming a certain buffer space so that external forces do not directly and vertically act on the heater body 3 during impact or tipping. This achieves force dispersion and buffering, effectively reducing the concentration of impact energy, thereby reducing the risk of damage to the internal components, connecting parts and other structures of the heater, improving the overall impact resistance and safety of use, and effectively enhancing the protective effect of the protective mesh frame on the heater body 3.

[0037] like Figure 5 As shown, the first frame 1 is further provided with a protective net structure 100.

[0038] Furthermore, both the first frame 1 and the second frame 2 are made of metal, which improves the strength and durability of the protective mesh structure to adapt to the high-temperature environment of the heater during long-term operation and avoids structural loosening due to thermal deformation or aging.

[0039] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
