[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] Example: Figure 1-5 As shown, the utility model provides a DC combiner box with a protective device, comprising a DC combiner box body 1, a protective mechanism 2 for use with the DC combiner box body 1 is provided at the top, and connecting mechanisms 3 for use with the DC combiner box body 1 are provided at both ends of one side.

[0021] The protective mechanism 2 includes a vertical plate 21 and an insertion plate 22. The vertical plate 21 is fixedly mounted on the top of the DC combiner box body 1, and the vertical plate 21 is symmetrical in structure. One end of the vertical plate 21 is slidably inserted with a symmetrically distributed insertion rod 23. A sliding hole 210 is provided at one end of the vertical plate 21, and the insertion rod 23 is slidably inserted in the sliding hole 210. The setting of the sliding hole 210 provides a guarantee for the stable sliding of the insertion rod 23, and the opposite ends of the insertion rod 23 are fixedly mounted with a push column 24, and the push column 24 is provided with a push hole 211 for matching use. The setting of the push hole 211 provides convenience for the convenient pushing of the push column 24. The outer side of the insertion rod 23 is movably sleeved with a spring 25, and the two ends of the spring 25 are respectively fixedly connected to the push column 24 and the vertical plate 21. A V-shaped top plate 26 is fixedly installed on the top of the plate 22, and a socket 27 is provided at one end of the plug-in plate 22, and a clamping rod 28 is fixedly inserted at the other end of the plug-in plate 22. A mounting hole 212 is provided at one end of the plug-in plate 22, and the clamping rod 28 is fixedly inserted in the mounting hole 212. The setting and use of the mounting hole 212 provide a guarantee for the stable installation of the clamping rod 28, and an L-shaped slot 29 is provided at the end of the vertical plate 21 away from the plug-in rod 23. The plug-in plate 22 can be slidably inserted between the two vertical plates 21, and the plug-in rod 23 can be slidably inserted in the socket 27. The outer diameter of the plug-in plate 22 is the same as the inner diameter between the two vertical plates 21, thereby ensuring the plug-in stability of the plug-in plate 22, and the clamping rod 28 can be slidably clamped in the L-shaped slot 29.

[0022] By adopting the above technical solution, when in use, the two push columns 24 are pushed to move backwards, thereby driving the two insertion rods 23 to move backwards and stretching the corresponding springs 25. When the distance between the two insertion rods 23 is moved to the maximum, the V-shaped top plate 26 is held and the insertion plate 22 is clamped between the two vertical plates 21. Then the clamping rod 28 is clamped into the L-shaped slot 29 and the insertion plate 22 is completely clamped into the two vertical plates 21. Then the two push columns 24 are released. At this time, the spring 25 will drive the corresponding push column 24 to reset, thereby driving the corresponding insertion rod 23 to reset and insert it into the socket 27, so that the V-shaped top plate 26 can be conveniently fixed. When the V-shaped top plate 26 needs to be replaced later, the above steps can be reversed.

[0023] The connecting mechanism 3 includes a side block 31, which is fixedly connected to the DC combiner box body 1, and a through hole 32 is opened on the side block 31. A side plate 33 is slidably connected to one side of the side block 31, and an array of through holes 34 are opened at the lower end of the side plate 33. A symmetrically arranged sliding post 37 is fixedly installed on one side of the side block 31, and the sliding post 37 is slidably inserted on the side plate 33. A symmetrically distributed sliding groove 38 is opened on one side of the side plate 33, and the sliding post 37 is slidably inserted in the sliding groove 38. The coordinated use of the sliding post 37 and the sliding groove 38 provides a guarantee for the stable sliding of the side plate 33 and the side block 31. An adjusting bolt 35 can be threadedly inserted in the through hole 34 and the through hole 32, and a fixing hole 36 for coordinated use is opened at the upper end of the side plate 33.

[0024] By adopting the above technical solution, when in use, the side panel 33 is fixed to the wall by using the fixing bolts and the fixing holes 36, and then the circuit is connected to the DC combiner box body 1. During this period, if the installation height of the DC combiner box body 1 needs to be adjusted, the four adjustment bolts 35 need to be turned in sequence and separated from the corresponding through holes 34. Then, according to the use requirements, the DC combiner box body 1 is moved to the appropriate height and the four adjustment bolts 35 are turned in reverse in sequence until the adjustment bolt 35 is threadedly inserted into another corresponding through hole 34.

[0025] Working Principle: During use, the side panels 33 are fixed to the wall by using the fixing bolts and fixing holes 36. Then, the circuits are connected to the DC combiner box body 1. During this period, if the installation height of the DC combiner box body 1 needs to be adjusted, the four adjustment bolts 35 are rotated in sequence to separate them from the corresponding through holes 34. Then, according to the use requirements, the DC combiner box body 1 is moved to the appropriate height and the four adjustment bolts 35 are rotated in the opposite directions in sequence until the adjustment bolts 35 are threaded into the other corresponding through holes 34.

[0026] When the line connection is completed, push the two push columns 24 to move backward, thereby driving the two insertion rods 23 to move backward and stretch the corresponding spring 25. When the distance between the two insertion rods 23 is moved to the maximum, hold the V-shaped top plate 26 and clamp the insertion plate 22 between the two vertical plates 21, then clamp the clamping rod 28 into the L-shaped slot 29 and completely clamp the insertion plate 22 into the two vertical plates 21, then release the two push columns 24. At this time, the spring 25 will drive the corresponding push column 24 to reset, thereby driving the corresponding insertion rod 23 to reset and insert it into the socket 27, so that the V-shaped top plate 26 can be conveniently fixed. When the V-shaped top plate 26 needs to be replaced later, just follow the above steps in reverse.

[0027] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
