Detailed Implementation

[0027] The present invention will be further described in detail below with reference to embodiments:

[0028] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0029] like Figures 1 to 8 As shown, a portable water heater housing connecting bracket includes: multiple outer brackets 1, which can be connected to a support surface. Each outer bracket 1 has a protruding connecting portion 11, a slot 111, and a first locking position 112 that allows it to pass laterally through; an inner bracket 2, which is connected to the back cover of the water heater. Each inner bracket 2 has a connecting rod 21 that can rotate relative to it. The connecting rod 21 has a locking portion 211 that can be engaged into the slot 111, and a groove 2 extending downwards from the upper end of the connecting rod 21. 12. The connecting rods 21 located on both sides of the groove 212 can undergo elastic deformation; the connecting bracket 3 is sleeved on the inner bracket 2, and a locking component 4 is provided between the connecting bracket 3 and the outer bracket 1 to lock the two together. The connecting bracket 3 is also provided with a positioning groove 31 into which the connecting rod 21 can be inserted. The connecting bracket 3 includes a first connecting piece 32 and a second connecting piece 33 that can be elastically deformed. When the locking component 4 is in the locked state, the free ends of the first connecting piece 32 and the second connecting piece 33 approach each other to lock the connecting bracket 3 and the connecting rod 21 together.

[0030] During installation, multiple outer brackets 1 are first installed onto the support surface using screws. Then, the connecting rod 21 is rotated so that the snap-fit ​​portion 211 at the upper end of the connecting rod 21 aligns with the snap-fit ​​groove 111. Next, the connecting bracket 3 is fitted over the connecting rod 21, so that the connecting rod 21 is snapped into the connecting bracket 3 through the positioning groove 31. At this time, the first connecting piece 32 and the second connecting piece 33 are in contact with the left and right sides of the groove 212 on the connecting rod 21. Then, the connecting bracket 3 and the outer bracket 1 are locked by the locking component 4. After locking, the water heater is pushed towards the connecting rod 21. During the approaching process, the inner bracket 2 gradually approaches and fits against the connecting rod 21, completing the installation of the connecting bracket. Because the connecting rod 21 on both sides of the groove 212 can undergo elastic deformation under the pressure of the first connecting piece 32 and the second connecting piece 33, the connection between the connecting rod 21 and the connecting bracket 3 can be made tighter, thus making the connection between the connecting rod 21 and the outer bracket 1 more secure.

[0031] The first connecting piece 32 and the second connecting piece 33 are spaced apart horizontally. The connecting bracket 3 also includes multiple connecting plates 34 that can connect the first connecting piece 32 and the second connecting piece 33. The multiple connecting plates 34 are spaced apart vertically, and the free ends of the first connecting piece 32 and the second connecting piece 33 are spaced apart to form an opening 35. The inner surfaces of the first connecting piece 32 and the second connecting piece 33 and the multiple connecting plates 34 cooperate to form the positioning groove 31. When the fixing component is in the locked state, the free ends of the first connecting piece 32 and the second connecting piece 33 move closer to each other, causing the opening 35 to decrease. When the fixing component is in the unlocked state, the free ends of the first connecting piece 32 and the second connecting piece 33 move away from each other, causing the opening 35 to expand. The arrangement of the connecting plates 34 makes the connection between the first connecting piece 32 and the second connecting piece 33 more stable, and the arrangement of the opening 35 allows the first connecting piece 32 and the second connecting piece 33 to completely cover the outside of the connecting rod 21, enabling a tighter connection with the connecting rod 21. When the locking component 4 is in the locked state, the free ends of the first connecting piece 32 and the second connecting piece 33 move closer together, causing the opening 35 to decrease. At this time, the first connecting piece 32 and the second connecting piece 33 clamp the connecting rod 21. When the locking component 4 is in the unlocked state, the free ends of the first connecting piece 32 and the second connecting piece 33 move further apart, causing the opening 35 to expand. At this time, the first connecting piece 32 and the second connecting piece 33 are in the released state, and the connecting rod 21 can be removed from the connecting bracket 3.

[0032] Each of the connecting plates 34 is U-shaped and is welded to the inner sidewalls of the first connecting piece 32 and the second connecting piece 33, which facilitates processing. Moreover, the U-shaped shape of the connecting plate 34 provides sufficient space for welding at both ends.

[0033] The locking assembly 4 includes a flexible connecting strip 41 connected to the outer side of the inner bracket 2. Second locking positions 42 are provided on both sides of the connecting strip 41, and a third locking position 43 is provided on the latching part 211. The third locking position 43, the second locking position 42, and the first locking position 112 are on the same axis. The locking assembly 4 also includes a locking member 44 that can sequentially pass through the second locking position 42, the first locking position 112, and the third locking position 43 to lock the connecting strip 41, the latching part 211, and the outer bracket 1. By simultaneously locking the second locking position 42, the first locking position 112, and the third locking position 43 through the locking member 44, the connecting strip 41, the latching part 211, and the outer bracket 1 are locked together more securely.

[0034] The locking component 4 also includes a washer 45, which is disposed between the connecting strip 41 and the connecting part 11. The washer 45 is also provided with a fourth locking position 451 through which the locking member 44 can pass. The washer 45 can easily adapt to connecting strips of different lengths and connecting parts 11 of different thicknesses. This allows the same outer bracket 1 to be used, and the only things that need to be adjusted are the more easily manufactured washer 45 and connecting strip 41, which can reduce costs and broaden the range of compatibility.

[0035] The inner support 2 includes an L-shaped inner support body 22. Two protruding connecting blocks 221 are provided at the top of the inner support body 22, spaced apart. The top of a connecting rod 21 is rotatably connected between the two connecting blocks 221. A locking assembly 23 is also provided between the lower end of the connecting rod 21 and the inner support body 22 to lock them together. The locking assembly 23 locks the lower end of the connecting rod 21 to the inner support body 22, preventing the lower end of the connecting rod 21 from wobbling, resulting in a more stable and safer connection.

[0036] The locking assembly 23 includes a first locking position 231 vertically disposed at the lower end of the connecting rod 21, and a second locking position 232 disposed at the lower end of the inner support body 22. The locking assembly 23 also includes a locking member 233 that can pass through both the second locking position 232 and the first locking position 231 on one side to lock the lower end of the connecting rod 21 to the inner support body 22. The locking member 233 is a quick-release screw. By locking the connecting rod 21 to the inner support body 22, the lower end of the connecting rod 21 can be fixed, making the connection between the two more stable and secure.

[0037] The first connecting piece 32 and the second connecting piece 33 are arranged in an arc shape. Compared with a straight surface, the arc shape can increase the contact area, improve the friction, and make the clamping more stable.

[0038] The connecting rod 21 has a first arc-shaped surface 213 and a second arc-shaped surface 214 on its outer side. The first arc-shaped surface 213 and the second arc-shaped surface 214 can respectively abut against the inner wall surfaces of the first connecting piece 32 and the second connecting piece 33. The arrangement of the first arc-shaped surface 213 and the second arc-shaped surface 214 increases the contact area, making the clamping more stable. The arrangement of the first arc-shaped surface 213 and the second arc-shaped surface 214 allows the first connecting piece 32 and the second connecting piece 33 to fit more closely to the outer side of the inner bracket 2. This allows the first connecting piece 32 and the second connecting piece 33 to fit more tightly with the first arc-shaped surface 213 and the second arc-shaped surface 214 on the outer side of the inner bracket 2 after deformation.

[0039] The first connecting piece 32, the second connecting piece 33, and the multiple connecting plates 34 are connected in a triangular arrangement. This arrangement makes the structure more compact, and because of the triangular distribution, the first connecting piece 32 and the second connecting piece 33 can be clamped more evenly, resulting in a more stable clamping.

[0040] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
