DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0040] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0041] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

[0042] See also Figure 1 , Figure 2 , Figure 3 In a preferred embodiment of the utility model, based on the above problems existing in the prior art, a photoelectric mixing box is provided, comprising:

[0043] Box body 1, box body 1 is provided with a back hook 110, and the back hook 110 is used to hang on the mounting beam A1;

[0044] The first mounting brackets 2 are respectively arranged on both sides of the back of the box body 1;

[0045] The locking mechanism 3 is suspended on the mounting beam A1 to lock the mounting beam A1 and the corresponding first mounting bracket 2 .

[0046] Specifically, the main body of the optoelectronic hybrid box includes a box body 1, which integrates optoelectronic conversion, power management and necessary communication interfaces, etc., for realizing the conversion and processing of optoelectronic signals. In view of the problem that the traditional optoelectronic hybrid box adopts a wall-mounted installation structure, in the installation environment such as large overhead poles, due to the small space, the drilling and bolting operations are inconvenient, the installation efficiency is low and the fixation is not firm, which increases the difficulty and cost of later maintenance. In order to facilitate installation and fixation, the embodiment of the utility model proposes a optoelectronic hybrid box with an integrated installation and fixing part, and optimizes the box body design of the optoelectronic hybrid box. The structure of the installation and fixing part is composed of a back hook 110 on the box body, a first installation bracket 2 and a locking mechanism 3. The back hook 110 design is adopted to realize a quick and convenient initial hanging installation; then, the first installation bracket 2 and the locking mechanism 3 are used to further stabilize the installation, simplify the installation steps, reduce the installation difficulty, and significantly improve the installation efficiency, while ensuring the stability of the installation.

[0047] Further, such as Figure 1 As shown, the back hook 110 is composed of a horizontal first part and a vertical second part. The first part and the second part are both designed with a plate-like structure; one end of the horizontal plate is fixedly connected to the back of the box body 1, and the vertical plate extends downward from the other end of the horizontal plate. The vertical plate is J-shaped, and the J-shaped hook portion extends in a direction away from the box body 1.

[0048] Specifically, the horizontal plate and the box body 1 can be firmly connected by a variety of mature fixing technologies including but not limited to welding, bolt connection, riveting and snap connection to ensure the firmness and reliability of the connection. Furthermore, in order to enhance the integrity of the structure and reduce the complexity of assembly, the horizontal plate and the vertical plate are integrally formed.

[0049] Furthermore, the back hook 110 and the back of the box body 1 are overall shaped like an "inverted J", thereby ensuring that the box body 1 can be firmly fixed on the mounting beam A1 and can maintain a stable suspension state even in the face of vibration or external force; at the same time, the structure is easy to install and disassemble, providing convenience for subsequent maintenance and replacement.

[0050] Furthermore, two locking mechanisms 3 can be provided to enhance the stability of the installation. The two locking mechanisms 3 are respectively locked with the first mounting brackets 2 on both sides of the box body 1 to achieve stable installation of the optoelectronic hybrid box.

[0051] As a preferred embodiment, the locking mechanism 3 is a cable clamp structure.

[0052] Specifically, the cable clamp structure, also called a cable fixing clamp, has a strong clamping force and adjustability, ensuring that the photovoltaic mixing box can be firmly fixed.

[0053] As a preferred embodiment, the cable clamp structure includes:

[0054] A second mounting bracket 31;

[0055] A fixing frame 32, the fixing frame 32 is U-shaped, and one end arm of the U-shaped fixing frame 32 is fixedly connected to the end of the second mounting bracket 31;

[0056] The first bolt 33 and the end of the first bolt 22 are provided with a pad 331 , the first bolt 33 passes through the other end arm of the U-shaped fixing frame 32 , and the pad 331 at the end of the first bolt 33 abuts against the first mounting bracket 2 to lock the first mounting bracket 2 , the mounting beam A1 and the fixing frame 32 .

[0057] Specifically, the cable clamp structure is composed of a second mounting bracket 31, a fixing bracket 32 ​​and a first bolt 33. The fixing bracket 32 ​​is U-shaped, and one end arm of the U-shaped fixing bracket 32 ​​is firmly fixed to the end of the second mounting bracket 31 by welding, bolt connection or other means, and the other end arm is used to cooperate with the first bolt 33 to achieve locking of the first mounting bracket 2, the mounting beam A1 and the fixing bracket 32.

[0058] The end of the first bolt 33 is equipped with a pad 331. Due to the presence of the pad 331, the contact area can be increased, the pressure generated when the bolt is tightened can be dispersed, and damage to the first mounting bracket 2 can be prevented. The first bolt 33 passes through the other end arm of the U-shaped fixing frame 32, and by tightening the bolt, the pad 331 at its end abuts against the first mounting bracket 2. During the locking process, the rotation of the first bolt 33 compresses the pad 331, thereby generating a strong clamping force, firmly connecting the first mounting bracket 2, the mounting beam and the fixing frame 32 together, thereby realizing the locking function.

[0059] As a preferred embodiment, the first mounting bracket 2 is provided with a plurality of first mounting holes 21;

[0060] The second mounting bracket 31 is provided with a plurality of second mounting holes 311, and the second mounting holes 311 correspond to the first mounting holes 21 one by one;

[0061] The second bolt 34 with a nut passes through the first mounting hole 21 and the second mounting hole 311 in sequence to lock the first mounting bracket 2 and the second mounting bracket 31 .

[0062] Specifically, in this embodiment, by providing a plurality of first mounting holes 21 on the first mounting bracket 2 and providing corresponding second mounting holes 311 on the second mounting bracket 31, a second bolt 34 with a nut is used for further tightening, thereby further enhancing the stability of the installation.

[0063] As a preferred embodiment, a notch 211 is provided on one side of at least one first mounting hole 21;

[0064] The second bolt 34 with a nut is disposed in at least one second mounting hole 311 , and the second bolt 34 slides into the first mounting hole 21 through the notch 211 to lock the first mounting bracket 2 and the second mounting bracket 31 .

[0065] Furthermore, the first mounting hole 21 is a long hole, which is arranged along the length direction of the first mounting bracket 2. The notch 211 is provided on one side of the long hole.

[0066] Specifically, the stud (or screw) of the second bolt 34 is pre-passed through and installed in the second mounting hole 311. During the installation process, the locking mechanism 3 is moved as a whole to ensure that the stud directly approaches and aligns with the notch 211, slides into the first mounting hole 21 through the notch 211, and then tightens the nut on the second bolt 34 to achieve locking, which simplifies the installation steps and improves the installation efficiency.

[0067] Specifically, the installation and fixing process of the photoelectric mixing box includes the following steps:

[0068] First, if Figure 2 As shown, two locking mechanisms 3 are suspended on the mounting beam A1 inside the rod;

[0069] Then, if Figure 3 As shown, the two locking mechanisms 3 are moved to both sides along the mounting beam A1 to ensure that sufficient space is reserved for hanging the optoelectronic hybrid box;

[0070] Then, if Figure 4 As shown, the box body 1 is hung on the mounting beam A1 through the back hook 110 of the box body 1, thereby achieving the preliminary hanging of the box body 1.

[0071] Then, if Figure 5 and Figure 6 As shown, the locking mechanism 3 is horizontally slid so that the second bolt 34 equipped on the fixing frame 32 is aligned with the notch 211 of the first mounting hole 21 and locked;

[0072] Then, if Figure 7 As shown, tighten the first bolt 33 on the upper portion of the second mounting bracket 31. As the bolt rotates, the pad 331 is gradually compressed and generates a clamping force, tightly connecting the first mounting bracket 2, the mounting beam A1 and the fixing frame 32 together, thereby achieving a stable installation of the optoelectronic hybrid box.

[0073] As a preferred embodiment, wherein Figure 8 , Fig. 9 , Fig.10 , Fig.11 and Fig.12As shown, a flip bracket 4 is further provided inside the box body 1, and the flip bracket 4 includes a first bracket 41 for arranging the electrical connection layer 5 and a second bracket 42 for arranging the optical connection layer 6;

[0074] One end of the second bracket 42 is rotatably connected to one end of the first bracket 41, and the other end of the second bracket 42 is connected to the other end of the first bracket 41 through the first fastener 7 when closed;

[0075] A limiting member is provided at the rotation connection between the first bracket 41 and the second bracket 42 , and the limiting member limits the second bracket 42 when the second bracket 42 is opened to a predetermined position.

[0076] Specifically, the box body 1 of the optoelectronic hybrid box integrates an electrical connection layer 5 and an optical connection layer 6 to achieve optoelectronic conversion. In view of the problem that the prior art adopts a double-layer flip structure but has no limit design, which leads to interference between the upper and lower layers during installation and construction, the utility model adopts a limiter to achieve the limit of the relative rotation angle (or position) of the first bracket 41 and the second bracket 42 in the flip bracket 4.

[0077] Furthermore, the first fastener 7 is a spring-loaded hand screw.

[0078] As a preferred embodiment, wherein Fig.10 As shown, the rotation connection between the first bracket 41 and the second bracket 42 is connected by a screw-nut assembly 10 .

[0079] Further, such as Fig.12 As shown, the first bracket 41 includes a bottom plate 411 and a first side plate 412 and a second side plate 413 located on opposite sides. One end of the first side plate 412 is vertically arranged and fixedly installed with the bottom plate 411, and the other end of the first side plate 412 extends inward to form a horizontal fixed installation plate 414, and the fixed installation plate 414 is provided with a first through hole for the first fastener 7 to pass through.

[0080] Preferably, the width of the first side plate 412 may be less than or equal to the width of the bottom plate 411 .

[0081] One end of the second side plate 413 is vertically disposed and fixedly installed with the bottom plate 411 . The second side plate 413 is in a concave structure. Two opposite sides of the concave portion of the second side plate 413 are bent inwards and extend to form two vertical first connecting plates 415 .

[0082] Furthermore, the second bracket 42 is composed of a top plate 421. The top plate 421 is a "convex"-shaped structure, and two opposite sides of the protruding portion of the top plate 421 are bent inward and extend to form two vertical second connecting plates 422. The two second connecting plates 422 correspond to the two first connecting plates 415 respectively and are connected by the screw and nut assembly 10 to ensure that the second bracket 42 can rotate relative to the first bracket 41.

[0083] By providing a limiting member at the rotational connection between the first bracket 41 and the second bracket 42, namely, on the first connecting plate 415 and the second connecting plate 422, it is ensured that the second bracket 42 and the first bracket 41 are limited when a predetermined angle (or position) is reached.

[0084] As a preferred embodiment, wherein Fig.11 As shown, the limiting member is a ball spring pin 8.

[0085] Specifically, the ball spring pin 8 is usually composed of a pin body, a spring inside the pin body, and a ball 82, wherein the spring provides elastic force for the ball 82 so that the ball can be kept in a certain position; the ball 82 is used to limit the relative angle movement between the first bracket 41 and the second bracket 42.

[0086] As a preferred embodiment, the ball spring pin 8 is a ball spring pin with an external thread 82;

[0087] A through hole is provided at the rotation connection between the first bracket 41 and the second bracket 42;

[0088] A cylinder 9 is provided at the corresponding through hole on the second bracket 42, and the inner wall of the cylinder 9 is provided with an internal thread matching the external thread 82. The external thread 82 engages with the internal thread to screw the ball spring pin 8 into the cylinder, and the ball 81 of the ball spring pin 8 protrudes from the through hole of the first bracket 41.

[0089] Specifically, the first connecting plate 415 and the second connecting plate 422 are provided with through holes, a cylinder 9 with an inner thread on the inner wall is provided at the through hole, and a ball spring pin 8 is provided in the cylinder 9.

[0090] During the opening process of the flip bracket 4, once the through holes on the first connecting plate 415 and the second connecting plate 422 are aligned, the ball 81 of the ball spring pin 8 will automatically pop out under the action of the spring, so that the ball 81 is placed in the through hole and protrudes from the first connecting plate 415 of the first bracket 41, thereby realizing a seamless limiting and self-locking mechanism.

[0091] During the closing process of the flip bracket 4, the first bracket 41 is gently pressed, and the edge of the through hole of the first connecting plate 415 will contact and push the ball 81, causing the spring built into the ball spring pin 8 to be appropriately compressed. During this process, the ball 81 is pressed against the first connecting plate 415, providing the necessary buffer and adjustment space for the smooth closing of the bracket.

[0092] The embodiment of the utility model adopts a ball spring pin as a limiter to achieve self-locking / free opening of the flip.

[0093] The opening and closing process of the flip bracket 4 includes the following steps:

[0094] First, loosen the first fastener 7 (such as a spring hand screw);

[0095] Then, the horizontal second bracket 42 is flipped to a predetermined position (such as a 90° vertical position). During this process, the through holes on the first connecting plate 415 and the second connecting plate 422 are aligned, so that the ball 81 of the ball spring pin 8 is automatically popped out and placed in the through hole under the action of the spring to limit the position and avoid interference between the upper and lower brackets.

[0096] When the flip bracket needs to be closed, just press the first bracket 41 lightly. The inner edge of the through hole of the first connecting plate 415 pushes the ball 81, and the spring built into the ball spring pin 8 is compressed, causing the ball 81 to shrink, ensuring that the ball 81 is pressed against the first connecting plate 415 until the first bracket 41 is flipped to a horizontal position. Tighten the first fastener 7 (such as a spring hand screw) to lock the flip bracket.

[0097] The advantages or beneficial effects of adopting the above technical solution are: the utility model proposes a photovoltaic hybrid box with an integrated installation and fixing part, adopts a back hook design, and combines the cooperation of the first mounting bracket and the locking mechanism to further stabilize the installation, simplify the installation steps, reduce the installation difficulty, and significantly improve the installation efficiency; at the same time, the flip bracket uses a ball spring pin to limit the position to achieve self-locking / flipping.

[0098] The above are only preferred embodiments of the present invention, and are not intended to limit the implementation methods and protection scope of the present invention. Those skilled in the art should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the contents of this specification and illustrations should be included in the protection scope of the present invention.
