The machinery, parts and equipment all adopt the conventional models in the existing technology, and the circuit connection adopts the conventional connection method in the existing technology, which will not be described in detail here.

[0036] like Figures 1 to 9 As shown, a connection assembly for installing a photovoltaic inverter is used to hang the inverter body 5 at a specified position, including:

[0037] The wall-mounted bracket 2 is arranged on the back of the inverter body 5, and the wall-mounted bracket 2 has a limiting hole 21;

[0038] The connecting plate 3 is arranged on the back of the inverter body 5, and the gap between the connecting plate 3 and the inverter body 5 forms a clamping hole;

[0039] The wall mount 1 has a plug-in portion 11 and a support portion 12, the plug-in portion 11 and the support portion 12 are distributed up and down, the plug-in portion 11 can be inserted into the card hole and matched with the connecting plate 3, and the support portion 12 is used to abut against the wall mount bracket 2 to support the inverter body 5;

[0040] The clamping block 4 is rotatably mounted on a side of the supporting portion 12 away from the plug-in portion 11 . The clamping block 4 can be rotatably inserted into the clamping hole to be in a locked state and pulled out from the clamping hole to be in an unlocked state.

[0041] Specifically, the wall-mounted bracket 2 is an integrated structure with the inverter body 5 and is located at the lower part of the inverter body 5. The connecting plate 3 is detachably arranged on the inverter body 5 and is located at the upper part of the inverter body 5. The plug-in portion 11 is the upper end of the wall-mounted bracket 1, and the supporting portion 12 is located at the lower part of the wall-mounted bracket 1. The clamping block 4 is rotatably installed on the lower end surface of the supporting portion 12. When the inverter body 5 needs to be installed in the specified position, the wall mount 1 is first installed to the specified position. After the inverter body 5 is aligned with the wall mount 1, the inverter body 5 is moved downward, and then the plug-in portion 11 is inserted into the card hole until the plug-in portion 11 abuts against the bottom of the connecting plate 3 to support the inverter body 5. At this time, the bottom of the wall mount bracket 2 also abuts against the supporting portion 12 of the wall mount 1, and the inverter is supported again by the supporting portion 12; then the clamping block 4 is rotated toward the wall bracket direction until the clamping block 4 is inserted into and passes through the limiting hole 21, and the inverter body 5 is clamped and fixed to the wall mount 1 through the cooperation of the clamping block 4 and the wall mount bracket 2, and the up and down movement of the inverter is limited to prevent the inverter body 5 from moving upward after installation and disengaging from the plug-in portion 11 of the wall mount 1, so as to ensure the stability of the inverter body 5 after being hung on the wall; when the inverter body 5 needs to be disassembled, it is only necessary to rotate the clamping block 4 to pull out the limiting hole 21 and move the inverter body 5 upward. At the same time, the inverter body 5 is hung and fixed on the installation plane (i.e., the wall) through the cooperation between the wall mount 1 and the wall mount, and the fixing screws are removed, so that there is no need to lock the screws and professional tools during the installation process, which reduces the installation process and improves the installation efficiency. After installation, there are no exposed screws in the connection range between the inverter body 5 and the wall mount 1, which improves the aesthetics of the inverter body 5.

[0042] In other embodiments, in order to facilitate replacement of the wall-mounted bracket 2, the wall-mounted bracket 2 and the inverter body 5 can also be set to be detachably connected, and the connecting plate 3 can be detachably installed on the inverter body 5 by bolt fixing or snap fixing.

[0043] In some embodiments of the present application, one end of the card block 4 has a bending portion 41. When the card block 4 is rotated and inserted into the card hole, the bending portion 41 abuts against the side of the card block 4 away from the support portion 12 to limit the lateral movement of the inverter body 5.

[0044] Specifically, the clamping block 4 is rotated to be inserted into and pass through the limiting hole 21 of the wall-mounted bracket 2. When it is in a locked state, the bent portion 41 abuts against a side of the wall-mounted bracket 2 away from the supporting portion 12, thereby limiting the left and right movement of the inverter body 5, preventing the inverter body 5 from shaking easily after installation, and further improving the stability of the inverter body 5 after being hung on the wall.

[0045] In some embodiments of the present application, at least two arc-shaped bosses 121 are provided on a side of the support portion 12 close to the block 4, a groove 122 is opened at the end of the arc-shaped boss 121, and a convex portion 42 is provided on the side of the block 4 close to the support portion 12. The convex portion 42 cooperates with the grooves 122 of the arc-shaped bosses 121 on both sides, and is used to position the block 4 when it is in a locked state and an unlocked state, and to limit the rotation of the block 4.

[0046] Specifically, when the card block 4 is rotated to be inserted into and passes through the limiting hole 21 of the wall-mounted bracket 2 and is in the locked state, the convex portion 42 of the card block 4 cooperates with the arc-shaped boss 121 located on the rear side, and is positioned by snapping into the groove 122 of the rear arc-shaped boss 121 to prevent the card block 4 from easily rotating after being in the locked state; when the card block 4 is rotated to be in the unlocked state, the card block 4 can be rotated to cooperate with the arc-shaped convex strip located on the front side, and is positioned by snapping into the groove 122 of the front arc-shaped boss 121 to prevent the card block 4 from easily rotating after being in the unlocked state, and the free rotation of the card block 4 in the locked state and the unlocked state is limited by the cooperation of the convex portion 42 and the arc-shaped bosses 121 on both sides, further ensuring that the user can disassemble and assemble the inverter body 5 well, thereby improving efficiency.

[0047] In some embodiments of the present application, at least part of one side of the card block 4 extends downward to form a handle portion 43. Specifically, with the provision of the handle portion 43, the user can rotate the card block 4 through the handle portion 43 to lock or unlock the inverter body 5, and the handle portion 43 and the bending portion 41 are respectively located on opposite sides of the rotation point of the card block 4, so that the user can rotate the card block 4 with less effort.

[0048] In some embodiments of the present application, at least two support parts 12 and at least two block blocks 4 are provided, which are respectively distributed on opposite sides of the wall mount 1; at least two wall mount brackets 2 are also provided, which respectively cooperate with the support parts 12 and the block blocks 4 on both sides.

[0049] Specifically, the two support parts 12 are respectively located at the left and right ends of the lower side of the wall-mounted bracket 2, and the two clamping blocks 4 are respectively rotatably installed at the bottom of the two support parts 12. The two wall-mounted brackets 2 are also respectively located at the left and right parts of the lower side of the inverter body 5. The inverter body 5 is supported by the cooperation of the two wall-mounted brackets 2 and the support parts 12, and the two clamping blocks 4 cooperate with the limiting holes 21 of the wall-mounted bracket on the same side to clamp and limit the two sides of the inverter body 5. The stability of the inverter body 5 after being hung on the wall is further improved.

[0050] In some embodiments of the present application, the wall mount 1 has a front side facing the inverter body 5 and a back side for abutting against the installation plane. The wall mount 1 is provided with at least two baffles 123, and the two baffles 123 are respectively abutted against the end faces of the support parts 12 on both sides.

[0051] Specifically, when the inverter body 5 is initially mounted on the wall mount 1 through the plug-in portion 11 and the support portion 12 (i.e., when the block 4 is in an unlocked state), the front end surfaces of the wall mount brackets on both sides of the inverter body 5 are in contact with the blocking pieces 123 on both sides of the wall mount 1, respectively. Through the cooperation of the blocking pieces 123 on both sides, the inverter body 5 is aligned and positioned, so that the inverter body 5 is placed in a horizontal straight line to prevent skewing, thereby ensuring a good installation effect of the inverter body 5.

[0052] In some embodiments of the present application, the blocking piece 123 includes a first bending portion 1231 and a second bending portion 1232. The first bending portion 1231 is gradually bent downward toward the front direction of the wall-mounted bracket 2, and the second bending portion 1232 is formed by bending part of the first bending portion 1231 downward, and the second bending portion 1232 is vertical.

[0053] Specifically, after the inverter body 5 is aligned with the wall bracket 1, in the process of moving the inverter body 5 downward, the wall bracket 2 first contacts the inclined first bending portion 1231, and is guided by the inclined surface of the first bending portion 1231 to drive the wall bracket to gradually align with the second bending portion 1232, thereby positioning the inverter body 5; at the same time, the first bending portion 1231 can also have a buffering effect on the placement of the inverter body 5, thereby preventing the wall bracket 2 from moving downward and directly colliding with the support portion 12 of the wall bracket 1.

[0054] In some embodiments of the present application, the plug-in portion 11 is L-shaped and is bent toward the front direction and the top of the wall mount 1 in sequence. After the plug-in portion 11 is inserted into the card hole, it abuts against the bottom of the connecting plate 3. Specifically, after the wall mount 1 is installed on the installation plane, there is an accommodation space for accommodating the connecting plate 3 between the L-shaped plug-in portion 11 and the installation plane, and the inverter body 5 moves down to contact the lower part of the plug-in portion 11 in a straight shape, and is supported by the lower part of the plug-in portion 11. The plug-in portion 11 and the wall mount 1 are an integrated structure, ensuring that the wall mount 1 has a high support strength.

[0055] In some embodiments of the present application, both sides of the top of the plug-in portion 11 are provided with chamfers to form guide slopes 111. Specifically, the setting of the guide slopes 111, when the inverter body 5 is aligned with the wall mount 1, in the process of moving the inverter body 5 downward, if there is a deviation between the plug-in portion 11 and the card hole, the bottom of the connecting plate 3 will first contact the guide slopes 111 of the plug-in portion 11, and through the guiding effect of the guide slopes 111, the plug-in board is gradually aligned with the card hole, and then inserted into and passes through the card hole, thereby improving the simplicity and smoothness of the installation of the inverter body 5.

[0056] According to the disclosure and teaching of the above description, the technicians in the field of the utility model can also change and modify the above implementation. Therefore, the utility model is not limited to the above specific implementation, and any obvious improvement, replacement or modification made by the technicians in this field on the basis of the utility model belongs to the protection scope of the utility model. In addition, although some specific terms are used in this specification, these terms are only for the convenience of explanation and do not constitute any limitation to the utility model.
