Detailed Implementation

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0028] It should be noted beforehand that the directional limitations regarding front, rear, left, and right in this utility model are only for ease of understanding of the technical solution. The directional limitations regarding front, rear, left, and right in the following description of this utility model are based on a single, independently installed ceiling electromechanical heating mounting plate.

[0029] like Figure 1 and Figure 2 As shown, the ceiling-mounted electric heating mounting plate 10 of this utility model includes a horizontally arranged first horizontal plate portion 11, which has a ceiling-mounted top plate fixing connection structure. The right end of the first horizontal plate portion 11 has a vertically extending first vertical plate portion 12, the upper end of the first vertical plate portion 12 has a horizontally extending second horizontal plate portion 13, and the right end of the second horizontal plate portion 13 has a vertically extending second vertical plate portion 14. The upper surface of the second horizontal plate portion 13 is a horizontal positioning mounting surface for the electric heating assembly, and the left side of the second vertical plate portion 14 is a vertical positioning mounting surface for the electric heating assembly. The second vertical plate portion 14 has a first bolt fitting hole 15 for connecting and fixing the electric heating assembly 20, and the axis of the first bolt fitting hole 15 is horizontally arranged in the left-right direction. The first horizontal plate portion 11, the first vertical plate portion 12, the second horizontal plate portion 13, and the second vertical plate portion 14 are typically integrally formed sheet metal structural parts.

[0030] In some preferred embodiments, to improve structural reliability and facilitate processing and assembly, a first reinforcing rib 16 is provided at the intersection of the upper surface of the first horizontal plate portion 11 and the left side of the first vertical plate portion 12; the first reinforcing rib 16 is a convex structure integrally formed with respect to the first horizontal plate portion 11 and the first vertical plate portion 12. The number of first reinforcing ribs 16 can be flexibly designed according to actual conditions; the embodiment shown in the figure has two first reinforcing ribs 16. Providing first reinforcing ribs 16 increases the overall structural strength of the ceiling electromechanical heating mounting plate 10, and the convex structure of the first reinforcing ribs 16 facilitates mass production. Similarly, to improve structural reliability and facilitate processing and assembly, in some preferred embodiments, a second reinforcing rib 17 can also be provided at the intersection of the right side of the first vertical plate portion 12 and the lower surface of the second horizontal plate portion 13; the second reinforcing rib 17 is a convex structure integrally formed with respect to the first vertical plate portion 12 and the second horizontal plate portion 13. The number of second reinforcing ribs 17 can be flexibly designed according to actual conditions; the embodiment shown in the figure has two second reinforcing ribs 17.

[0031] In some preferred embodiments, to improve structural reliability and facilitate processing and assembly, the front and rear ends of the right side of the second vertical plate 14 are respectively provided with first bent edges 18 formed by bending 180° to the right relative to the second vertical plate 14. The first bent edges 18 are in close contact with the right side of the second vertical plate 14, that is, the first bent edges 18 adopt a pressed edge structure to ensure the overall strength of the part where the second vertical plate 14 is located. To improve the strength of the bolt connection structure and facilitate processing, the first bolt mating holes 15 are preferably integrally formed with respect to the second vertical plate 14 with a flanged hole structure. The number of first bolt mating holes 15 can be flexibly designed according to the actual situation. In the embodiment shown in the figure, each ceiling electromechanical heating mounting plate 10 is designed with two first bolt mating holes 15.

[0032] The ceiling-mounted unit top plate fixing connection structure provided with the first horizontal plate 11 is the corresponding structure used to fix the ceiling-mounted unit electric heating mounting plate 10 to the first horizontal plate 11. It is generally fixed by bolt connection, meaning the first horizontal plate 11 is generally designed with at least a second bolt mating hole 19. To improve structural reliability and facilitate processing and assembly, the preferred embodiment of the ceiling-mounted unit top plate fixing connection structure of the first horizontal plate 11 includes a second bolt mating hole 19, a first locking part 110, and a second locking part 111. The axis of the second bolt mating hole 19 is vertically oriented, penetrating both the upper and lower surfaces of the first horizontal plate 11. The first locking part 110 is located at the front and rear ends of the first horizontal plate 11, extending vertically downwards relative to the lower surface of the first horizontal plate 11. The second locking part 111 is located at the left end of the first horizontal plate 11 via a transition connection, and is horizontally arranged with its position lower than that of the first horizontal plate 11. The first horizontal plate portion 11, the first snap-fit ​​portion 110, the transition connection portion and the second snap-fit ​​portion 111 are usually integrally formed sheet metal structural parts.

[0033] To improve structural reliability and facilitate processing and assembly, a limiting protrusion 112 is provided on the upper surface of the transition connection. The limiting protrusion 112 serves two purposes: it acts as a reinforcing rib and it also controls the assembly stroke of the second snap-fit ​​part 111, providing a pre-positioning function to prevent over-insertion and subsequent installation difficulties. Understandably, to facilitate snap-fit ​​assembly, the insertion end of the first snap-fit ​​part 110 can be equipped with a guide bevel structure or a guide fillet structure, and the insertion end of the second snap-fit ​​part 111 can also be equipped with a guide bevel structure or a guide fillet structure.

[0034] See Figures 1 to 5To ensure a simple, reliable, and easy-to-assemble structure, and to facilitate the routing of electric heating cables, the front and rear ends of the right side of the first vertical plate 12 each have a second bent edge 113 extending to the right (to effectively ensure structural strength, the bending angle of the second bent edge 113 is no greater than 90°, i.e., the included angle between the right side of the first vertical plate 12 and the inner side of the second bent edge 113 is an obtuse angle or a right angle). The second bent edge 113 is provided with a horizontally arranged snap-fit ​​hole 114 along its axis in the front-rear direction. This snap-fit ​​hole 114 is used to connect the cable mounting plate 40. The number of snap-fit ​​holes 114 can be flexibly designed according to actual conditions. In the embodiment shown in the figure, each second bent edge 113 is designed with two snap-fit ​​holes 114. The shape of the snap-fit ​​hole 114 can be matched with the cable snap-fit ​​plates 41 at both ends of the cable mounting plate 40. The snap-fit ​​hole 114 is generally preferably a rectangular hole. To facilitate snap-fit ​​assembly, the insertion end of the cable snap-fit ​​plate 41 can also be provided with a guide bevel structure or a guide rounded corner structure. During actual assembly, the insertion direction of the wiring clip plate 41 corresponds to the axial direction of the clip hole 114, which is also the length direction of the wiring mounting plate 40.

[0035] Further reading Figures 6 to 10 Based on the aforementioned ceiling-mounted electric heating mounting plate, this utility model also provides a ceiling-mounted machine, including a ceiling-mounted machine top plate 30 and an electric heating component 20. The electric heating component 20 includes electric heating fixing brackets 21 located at both ends of its length direction. Each electric heating component 20 has a ceiling-mounted electric heating mounting plate 10 corresponding to both ends of its length direction. The first horizontal plate portion 11 of the ceiling-mounted electric heating mounting plate 10 is fixedly connected to the ceiling-mounted machine top plate 30 through a ceiling-mounted machine top plate fixing connection structure. The electric heating fixing brackets 21 are installed and positioned through the horizontal positioning mounting surface and the vertical positioning mounting surface of the electric heating component in the ceiling-mounted electric heating mounting plate 10, and are connected and fixed to the first bolt mating hole 15 in the ceiling-mounted electric heating mounting plate 10 by the first bolt. That is, the electric heating fixing brackets 21 have bolt connection holes that match the first bolt.

[0036] The electric heating assembly 20 is a commercially available standard product, essentially consisting of electric heating mounting brackets 21 at both ends. During assembly, one electric heating assembly 20 and two ceiling-mounted unit electric heating mounting plates 10 are typically assembled into a single unit. Then, the two first horizontal plates 11 of this unit are connected and fixed to the ceiling-mounted unit's top plate 30. In implementing this invention, only multiple identical ceiling-mounted unit electric heating mounting plates 10 need to be mass-produced, allowing for interchangeability when installing multiple electric heaters, significantly reducing the overall product cost.

[0037] In the preferred fixed installation method, the ceiling-mounted electric heating mounting plate 10 includes a second bolt mating hole 19, a first snap-fit ​​part 110, and a second snap-fit ​​part 111. The axis of the second bolt mating hole 19 is vertically arranged and penetrates the upper and lower surfaces of the first horizontal plate part 11. The first snap-fit ​​part 110 is respectively located at the front and rear ends of the first horizontal plate part 11 and extends vertically downward relative to the lower surface of the first horizontal plate part 11. The second snap-fit ​​part 111 is located at the left end of the first horizontal plate part 11 through a transition connection part. The second snap-fit ​​part 111 is horizontally arranged and its position is lower than that of the first horizontal plate part 11. A limiting protrusion 112 is provided on the upper surface of the transition connection part. The ceiling-mounted unit top plate 30 has a first surface facing the first horizontal plate portion 11 and a second surface facing away from the first horizontal plate portion 11. Corresponding to the ceiling-mounted unit top plate fixed connection structure on the ceiling-mounted unit electric heating mounting plate 10, the first surface of the ceiling-mounted unit top plate 30 has a positioning protrusion 31 and a positioning locking hole 32. One side of the positioning protrusion 31 has a locking interface 33 for the second locking part 111 to be inserted into. The second locking part 111 and the positioning protrusion 31 form a locking and limiting cooperation. The first locking part 110 and the positioning locking hole 32 form a locking and limiting cooperation. The ceiling-mounted unit top plate 30 has a second bolt connection hole corresponding to the second bolt mating hole 19. The ceiling-mounted unit top plate 30 and the first horizontal plate portion 11 are connected and fixed by the cooperation of the second bolt with the second bolt mating hole 19 and the second bolt connection hole. During the specific assembly, the second snap-fit ​​part 111 is first inserted into the snap-fit ​​interface 33 at a certain angle. Then, as the second snap-fit ​​part 111 is gradually snapped into the inner cavity of the positioning protrusion 31, the first snap-fit ​​part 110 is simultaneously inserted into the positioning snap-fit ​​hole 32 until the first snap-fit ​​part 110 and the second snap-fit ​​part 111 are installed in place at the same time. At this time, the first horizontal plate part 11 and the first surface of the ceiling machine top plate 30 are in planar contact, and the second bolt mating hole 19 and the second bolt connecting hole are aligned with each other. Finally, the second bolt is tightened and fixed.

[0038] To ensure a simple, reliable, and easy-to-assemble structure, and to facilitate the wiring of the electric heating components, in a preferred embodiment of the ceiling-mounted machine's electric heating mounting plate 10, the front and rear ends of the right side of the first vertical plate portion 12 of the mounting plate 10 each have a second bent edge 113 extending to the right. The second bent edge 113 is provided with a snap-fit ​​hole 114 arranged horizontally along its axis in the front-rear direction. Correspondingly, during the assembly of the ceiling-mounted machine, multiple electric heating components 20 are arranged in a ring at intervals. At least one electric heating component 20 is positioned below a wiring mounting plate 40. Wiring snap-fit ​​plates 41 are fixedly installed at both ends of the wiring mounting plate 40 along its length. The snap-fit ​​plates 41 engage with the snap-fit ​​holes 114 on the second bent edge 113. The arrangement of the wiring mounting plate 40 can be designed according to the location of the electrical control box and the distribution of the multiple electric heating components 20. For example... Figure 10 In the illustrated embodiment, the three electric heating components 20 are respectively designated as a first electric heating component 22, a second electric heating component 23, and a third electric heating component 24. If the control box is located in the vicinity of the first electric heating component 22 away from the end of the second electric heating component 23, wiring mounting plates 40 need to be installed in the lower areas of the first electric heating component 22 and the lower areas of the second electric heating component 23. If the control box is located in the vicinity of the first electric heating component 22 close to the end of the second electric heating component 23, then generally only the wiring mounting plate 40 needs to be installed in the lower area of ​​the second electric heating component 23.

[0039] For an electric heating component 20 with a wiring mounting plate 40 located directly below it, during assembly, the wiring mounting plate 40 is typically first connected and positioned to the two corresponding ceiling-mounted electric heating mounting plates 10, and then the electric heating component 20 is installed and fixed. Once the two ceiling-mounted electric heating mounting plates 10 and the electric heating component 20 are connected and fixed into a whole using the first bolt, the wiring mounting plate 40 is also fixed in place.
