DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, but not all the embodiments.

[0029] Embodiment one:

[0030] A decorative strip of a water heater, comprising a surface assembly 1 for decoration on the outer side of a shell, such as Figure 1 , 2The display shows a decorative strip style of L-shaped folding edge, and other styles of decorative components 1 can also be used in actual use. The decorative components 1 are provided with anti-disassembly buckle structure 2, which is used to form an anti-disassembly connection with the shell. This anti-disassembly connection can make the manufacturer conveniently assemble and install the decorative strip or conveniently disassemble it, and the fixing effect is more firm than the magnetic decorative strip cited in the background art.

[0031] Specifically, as Figure 3 The anti-disassembly buckle structure 2 includes a mounting cavity 3 and a locking pin structure 4. The mounting cavity 3 is provided on the decorative component 1 and is a cylindrical hollow cavity. Since the mounting cavity 3 is provided with a locking pin structure 4 of a certain thickness inside, the mounting cavity 3 has a certain thickness. The mounting cavity 3 protrudes from the inner surface of the decorative component 1 to the inside, so the shell in the water heater is provided with a corresponding groove at the position corresponding to the mounting cavity 3. During use, the mounting cavity 3 is inserted into the corresponding groove, which can achieve the effect of fixing and assist the accurate position installation of the decorative component 1.

[0032] The locking pin structure 4 is provided in the mounting cavity 3 and is rotationally connected with the mounting cavity 3. The locking pin structure 4 is coaxially arranged with the mounting cavity 3. The locking pin structure 4 includes a driving part 5 and a driven part 6. The driving part 5 and the driven part 6 can be independently rotated in the mounting cavity 3, and neither of them can be axially displaced. As Figure 3 The mounting cavity 3 is filled with the driving part 5 and the driven part 6 in the axial direction, and the end surfaces of the driving part 5 and the driven part 6 in contact with each other are smoothed as much as possible to reduce the friction. Thus, the driving part 5 and the driven part 6 can be rotated respectively. During actual use, a ball can be arranged between the driving part 5 and the driven part 6 to reduce the friction, so that the rotation of the driving part 5 and the driven part 6 is more smooth.

[0033] The driving part 5 is provided with an inner cavity one 7 in the axial direction, the driven part 6 is provided with an inner cavity two 8, the opening of the inner cavity one 7 and the inner cavity two 8 are oppositely arranged, the openings of the inner cavity one 7 and the inner cavity two 8 are both towards the side of the driving part 5 and the driven part 6, so when the driving part 5 rotates, the opening of the inner cavity one 7 can coincide with the opening of the inner cavity two 8 or the two openings are misaligned with the rotation of the driving part 5, the inner cavity one 7 is provided with a top pin 9, the inner cavity two 8 is provided with an armature 10 which is slidably connected; the inner cavity one 7 is further provided with a spring 13, the spring 13 is located at the inner bottom end of the inner cavity one 7, the spring 13 pushes the top pin 9 to one side of the opening. Further, the armature 10 is in a cylindrical structure, the length of the armature 10 is the same as the length of the inner cavity two 8, so when the armature 10 is completely immersed in the inner cavity two 8, the opening end of the driven part 6 forms a plane, at this time the driving part 5 and the driven part 6 are separated from each other, and because the top pin 9 is pushed against the driven part 6 under the action of the spring 13, the armature 10 cannot enter the inner cavity one 7, so at this time no matter how the driving part 5 rotates, it cannot drive the driven part 6 to rotate, that is, when the contact surface of the armature 10 and the top pin 9 coincides with the contact surface of the driving part 5 and the driven part 6, the driving part 5 and the driven part 6 are in a separated state;

[0034] When the manufacturer needs to maintain the equipment, the driving part 5 can be first rotated to make the opening of the inner cavity one 7 coincide with the opening of the inner cavity two 8, and then a special disassembling device 11 is used for disassembly, the end of the disassembling device 11 is provided with a magnet 12, the function of the magnet 12 is to attract the armature 10 to move into the inner cavity one 7; in actual use, when the inner cavity one 7 and the inner cavity two 8 are aligned, a mark can be set on the outer surface of the facing assembly 1, when the driving part 5 is rotated to align the mark point, the two openings can be aligned, as shown in Figure 4 The attraction force of the magnet 12 to the armature 10 should be smaller than the elastic force of the spring 13, under the action of the magnetic force, the armature 10 is pulled into the inner cavity one 7, the driving part 5 and the driven part 6 are combined, when the armature 10 moves into the inner cavity one 7, the driving part 5 can drive the driven part 6 to rotate, at this time, the driven part 6 can be smoothly rotated by rotating the driving part 5 again, after the driven part 6 is rotated, the assembly or disassembly of the facing assembly 1 can be realized; this anti-disassembly bayonet structure has no magnetic elements inside, it is not easy to cause the phenomenon of magnetic dust on the surface, and it cannot be disassembled by the user when the user does not understand the internal structure, so it can effectively prevent the user from disassembling the machine privately.

[0035] Example two:

[0036] In actual use, if the inner cavity 7 is designed as a straight-through cylindrical inner hole, the ejector pin 9 is always in the ejected position under the action of the spring 13, which is not convenient for the assembly of the product. Therefore, the opening of the inner cavity 7 is provided with a stepped necking 14, and the ejector pin 9 matched with the necking 14 is provided with a T-shaped cross section. The ejector pin 9 has a top end 15 penetrating through the necking 14, so that the ejector pin 9 can be limited by the necking 14 and always keep the top end 15 flush with the end surface of the driving part 5. Since the moving part for connecting the driving part 5 and the driven part 6 is the armature 10, the function of the ejector pin 9 is to push the armature 10 to prevent it from being immersed in the inner cavity 1. Therefore, the end of the ejector pin 9 is always flush with the end surface in the normal state.

[0037] Embodiment three:

[0038] In actual use, although the top end 15 and the top end 16 are designed as flat top to achieve the function as mentioned above, the fault tolerance of the flat surface is low. If the top end 16 of the armature 10 is stuck at the opening of the inner cavity 7 due to vibration or other reasons, the driving part 5 and the driven part 6 can also be connected. The difference between this embodiment and the previous embodiment is that, as shown in Figure 5 , the armature 10 is provided with the top end 16 at the opening of the inner cavity 2 8. The top end 15 and the top end 16 are both designed as a round top 17. When the round top 17 is designed, the surface contact of the original top end 15 and the top end 16 is changed to point contact. In this way, the limitation of the armature 10 is not affected, the driving part 5 cannot be easily connected with the driven part 6, and the free rotation of the driving part 5 is more smooth.

[0039] Embodiment four:

[0040] As shown in Figure 2 , 4 , the driving part 5 is provided with a twisting part 18 penetrating through the surface assembly 1. The end surface of the twisting part 18 is provided with an inner recessed cross slot 19. The disassembler 11 further includes a driving rod 24 and a cross bit 25. The driving rod 24 is fixedly arranged on one side of the magnet 12, and the cross bit 25 is fixedly arranged on the other side of the magnet 12. In actual use, the disassembler 11 is similar in structure to the cross screwdriver commonly used, and the difference is that the end part is provided with a magnet 12 specially used for attracting the armature 10. The diameter of the magnet 12 is not less than the inner diameter of the installation cavity 3. When the cross bit 25 is inserted into the cross slot 19 and the driving part 5 is rotated to the mark on the surface of the surface assembly 1, the opening of the driving part 5 and the driven part 6 is aligned. At this time, the magnet 12 acts to pull the armature 10, and then the driven part 6 can be twisted.

[0041] Embodiment five:

[0042] According to the method for marking the sign on the surface of the facing assembly 1 as described in the foregoing embodiments, it is appropriate to design the locking nail structure 4 to have a rotation angle of no more than 180 degrees for locking or unlocking; as shown in Figure 6 The locking column 20 and the locking rod 21 pass through the through hole 23 in the shell of the water heater, and the arc-shaped slope 22 is arranged on the inner side of the through hole 23. The arc-shaped slope 22 cooperates with the locking rod 21 to enable the facing assembly 1 to be buckled on the shell. During installation, the locking column 20 and the locking rod 21 pass through the through hole 23. When the locking column 20 is rotated by using the dismounting device 11, the locking rod 21 cooperates with the slope of the arc-shaped slope 22 to realize the tensioning of the locking column 20. When the rotation reaches a preset locking angle, the locking of the facing assembly 1 is completed. At this time, the locking rod 21 is located at the highest point of the slope of the arc-shaped slope 22, so that the locking column 20 can be always tensioned. Since the locking or unlocking angle of the locking nail structure 4 can be preset, the alignment of the inner cavity 7 and the inner cavity 8 can be realized by marking on the outer surface of the facing assembly 1.

[0043] The above description is only the preferred embodiment of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can make equivalent replacements or changes to the technical solution and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered by the protection scope of the present application.
