Description

Technical Field

[0001] This utility model relates to the field of photovoltaic inverter technology, and in particular to a tool-free installation safety screw photovoltaic inverter wall mount. Background Technology

[0002] In photovoltaic energy storage systems, the photovoltaic inverter, as the core power conversion device of the photovoltaic power generation system, directly affects the system's operational safety through its installation stability. The wall mount, as a crucial connection structure between the inverter and the building facade, must balance quick assembly / disassembly, earthquake resistance, and reliable fixation in extreme environments. While the currently prevalent exposed safety screw locking solution achieves a mechanical connection between the inverter and the wall mount, this design results in screws being constantly exposed on the outside of the equipment. This not only detracts from the overall aesthetics of the product but also forces installers to rely on special tools in confined installation spaces. This tool dependence significantly reduces construction efficiency and increases the risk of installation failure due to frequent on-site tool compatibility issues. Furthermore, the tightening and loosening of exposed screws is not convenient enough for frequent maintenance scenarios, failing to meet users' core demand for efficient and easy operation. Utility Model Content

[0003] In view of this, the present invention addresses the deficiencies of the existing technology, and its main objective is to provide a tool-free installation safety screw photovoltaic inverter wall mount, which solves the technical problems of existing photovoltaic inverter wall mounts that rely heavily on installation tools, are inconvenient to operate in narrow spaces, have low construction efficiency, and have poor appearance integrity due to the use of exposed safety screws.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: This utility model discloses a tool-free installation safety screw photovoltaic inverter wall mount, comprising a frame body, one end of which has a protruding guide plug plate, and the end of the guide plug plate away from the frame body has a guide plug interface, which gradually expands from the position close to the frame body to the direction away from the frame body. The two symmetrically mounted knob plungers for detachable insertion and connection with the photovoltaic inverter are installed on both sides of the end of the frame body away from the guide plug plate, and the two knob plungers are arranged facing each other.

The support protrusion is disposed between the two knob plungers and is spaced apart from the two knob plungers.

[0006] As a preferred embodiment, the side of the plug-in ear plate near the first support plate is further provided with a limiting pin, the length of which is equal to the vertical straight distance from the plug-in ear plate to the first support plate. The second support plate is also provided with an avoidance notch in the middle that communicates with the guide plug-in interface. The connection between the first support plate and the second support plate is provided with an engagement limiting groove that communicates with the avoidance notch.

[0007] As a preferred embodiment, the knob plunger is mounted on both symmetrical sides of the end of the frame away from the first support plate via mounting lugs, with the mounting lugs extending along the side closer to the insertion lug plate.

[0008] As a preferred embodiment, the knob plunger includes a stud, an elastic element, and a pin. The stud is installed on one side of the two mounting lugs that are close to each other.

[0018] Please see Figures 1 to 4 This utility model provides a tool-free installation safety screw photovoltaic inverter wall mount, including a frame 10. The frame 10 serves as the main load-bearing and installation base, ensuring overall structural stability and support strength. A guide plug-in plate 20 protrudes from one end of the frame 10 for initial alignment and connection with the photovoltaic inverter, simplifying the installation process and improving guiding accuracy. Specifically, a guide plug-in interface 30 is provided at the end of the guide plug-in plate 20 away from the frame 10. The guide plug-in interface 30 accommodates and guides the mating components on the photovoltaic inverter, enabling quick insertion and reducing installation resistance. The guide plug-in interface 30 gradually widens from the position near the frame 10 towards the direction away from the frame 10, forming a flared structure to compensate for installation deviations, enabling blind insertion and adapting to operation in narrow spaces. Symmetrically mounted on both sides of the end of the frame 10 away from the guide plug-in plate 20 are rotary plungers 40 for detachable insertion with the photovoltaic inverter. The rotary plungers 40 serve as the final quick-locking and anti-detachment mechanism, ensuring reliable connection and tool-free operation. The two rotary plungers are positioned facing each other at 40° to ensure that a balanced locking force is applied from both sides, guaranteeing connection stability and preventing the photovoltaic inverter from accidentally falling off.

[0019] In this embodiment, the guide plug-in plate 20 includes a first support plate 21, a second support plate 22, and a plug-in ear plate 23 connected in sequence. The first support plate 21 forms a stable installation base structure, the second support plate 22 serves as a transition connection component and transmits force, and the plug-in ear plate 23 directly connects to the photovoltaic inverter and guides the plug-in process. The end of the first support plate 21 furthest from the second support plate 22 is connected to the frame 10 to ensure effective force transmission to the main structure. Both the first support plate 21 and the plug-in ear plate 23 are perpendicular to the second support plate 22, forming a rigid support frame to resist torsional loads during installation and operation. The first support plate 21 and the plug-in ear plate 23 are arranged in a staggered parallel configuration to optimize spatial layout. The plug-in ear plate 23 is fixed on both symmetrical sides of the second support plate 22, achieving dual-sided guidance to enhance docking stability. The plug-in ear plates 23 have guide ramps 231 on their adjacent sides, forming a gradually expanding entrance to compensate for alignment deviations and reduce plugging difficulty. The two guide ramps 231 together form the guide plug interface 30, creating a self-aligning channel for rapid blind plugging. A guide protrusion 24 protrudes from the end of the plug-in ear plate 23 away from the second support plate 22, further refining the guide path and providing precise positioning of the plug-in end. The two guide protrusions 24 are parallel and located on the same horizontal plane as the plug-in ear plates 23, ensuring guide continuity and preventing jamming. A support protrusion 50 is also provided at the end of the frame 10 away from the first support plate 21, providing auxiliary support for the bottom of the photovoltaic inverter and sharing the load. The support protrusion 50 is installed on the side of the frame 10 near the plug-in ear plate 23 and is perpendicular to the frame 10, forming a stable supporting plane. The support protrusion 50 is positioned between the two knob plungers 40 with a gap between them, avoiding interference with the locking mechanism while ensuring effective support.

[0020] Furthermore, a limiting pin 60 is also provided on the side of the plug-in ear plate 23 near the first support plate 21. The limiting pin 60 serves as a support and limiting pin, enhancing the safety against detachment. The length of the limiting pin 60 is equal to the vertical straight-line distance from the plug-in ear plate 23 to the first support plate 21, ensuring that the limiting depth accurately matches the structural gap and avoiding over-positioning or interference. The second support plate 22 also has an avoidance notch 221 in the middle that communicates with the guide plug interface 30, providing a movement channel for the photovoltaic inverter docking components and reducing structural interference. At the connection between the first support plate 21 and the second support plate 22, there is an interlocking limiting groove 211 that communicates with the avoidance notch 221, forming an interlocking structure with the features on the photovoltaic inverter to achieve mechanical locking and anti-loosening of the installation terminal.

[0021] The knob plunger 40 is mounted on both sides of the frame 10 away from the first support plate 21 via mounting lugs 70. The mounting lugs 70 provide a stable and symmetrical mounting base, ensuring a balanced distribution of the locking force of the knob plunger 40. The mounting lugs 70 extend along the side closer to the insertion lug plate 23, optimizing the lever arm structure to enhance the load-bearing capacity and ease of operation of the knob plunger 40.

[0022] The rotary plunger 40 includes a stud 41, an elastic element 42, and a pin 43. The stud 41 serves as the core support and connection base. The elastic element 42 provides continuous rebound force to achieve automatic reset and maintain a locked state. The pin 43 acts as the actuator, directly participating in the insertion and locking action. Specifically, the stud 41 is installed on one side of the two mounting lugs 70 that are close to each other. One end of the pin 43 passes through the mounting lugs 70 and the stud 41 in sequence and is fitted with an operating element 44, enabling manual operation and allowing users to lock and release without tools. The end of the pin 43 away from the operating element 44 has a protruding connector 431 for insertion into the corresponding hole of the inverter, forming a physical interlock. The elastic element 42 is sleeved on the pin 43 to ensure the linearity and stability of force transmission. One end of the elastic element 42 is connected to the connector 431, directly driving the connector 431 to complete the locking action, while the other end is connected to the stud 41, providing a reaction force fulcrum to maintain the elastic preload state.

[0023] In a preferred embodiment, the elastic element 42 is a spring, providing a stable and predictable elastic force to ensure reliable reset and sustained holding force of the locking mechanism. Furthermore, the outer periphery of the operating element 44 is provided with rough stripes 441 to increase friction during operation and enhance tool-free operation characteristics.

[0024] The stud 41 has a threaded connecting block 45 protruding at one end near the mounting lug 70, achieving a secure and adjustable connection with the mounting lug 70 for easy assembly and maintenance. The stud 41 is fixedly screwed to the mounting lug 70 via the threaded connecting block 45, ensuring the rigidity and stability of the overall structure and effectively transmitting locking force. The stud 41 has a mounting through hole, providing precise guidance and accommodating space for the pin 43 and the elastic element 42. One end of the pin 43 passes sequentially through the mounting lug 70, the threaded connecting block 45, and the mounting through hole, and is screwed to the operating element 44. A limiting block protrudes from the inner circumference of the mounting through hole near the operating element 44, limiting the compression stroke of the elastic element 42 and providing a reliable mounting base. The elastic element 42 is positioned within the mounting through hole to avoid external interference and ensure reliable operation. One end of the elastic element 42 is connected to the limiting block, and the other end is connected to the connector 431 to ensure smooth execution of the insertion and locking action.

[0025] When the rotary plunger 40 is in use, by turning the operating element 44, the two operating elements 44 are moved closer to each other, the elastic element 42 is compressed, and at the same time, the pin element 43 drives the plug 431 to move closer to the stud element 41. After it is in contact with the photovoltaic inverter, the operating element 44 is released, and the plug 431 is inserted into the docking hole of the photovoltaic inverter under the action of the restoring force of the elastic element 42, thereby achieving the locking effect.

[0026] Furthermore, the longitudinal section of the guide plug plate 20 is Z-shaped, and the multi-segment bending structure achieves multi-functional integration of guidance, support and limiting in a limited space. The guide plug interface 30 is flared, which significantly reduces the accuracy requirements of the initial docking, realizes true blind plugging and adapts to narrow installation environments.

[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the principles of the present utility model should be included within the protection scope of the present utility model.
