[0027] In order to make the utility model purposes, technical scheme carry out clearly, completely describe, and the advantage is more clear and distinct, the following combining the drawings to the utility model embodiment further detailed description.Should understand, the specific embodiment described here is a part of the embodiment of the utility model, rather than all the embodiment, only use to explain the embodiment of the utility model, and not for the limitation of the embodiment of the utility model, all other embodiments obtained by the ordinary skill in the art without doing the premise of the creative labor, belong to the scope of the protection of the utility model.

[0028] Embodiment one: please refer to Figures 1-7 The utility model provides a kind of technical scheme: a distributed photovoltaic power generation grid-connected box, including box body 3, the box body 3 is equipped with movable door 1, movable door 1 is equipped with door lock body 14, it is characterized by: the surface of movable door 1 is fixed with vertical plate 11, vertical plate 11 is equipped with two groups, two groups of vertical plate 11 are rotatably arranged with rotating shaft 10, rotating shaft 10 is fixedly connected to one end of connecting rod 12, the other end of connecting rod 12 is fixedly connected to cover 6.

[0029] The bottom end surface of cover 6 is fixed with insert ring 18, the bottom periphery of cover 6 is fixed with bottom ring 13, cover 6 is internally connected with inner cylinder 7 by thread, the inside of inner cylinder 7 is provided with internal thread 17, the outer wall of door lock body 14 is provided with external thread 15, and door lock body 14 is located in the inside of inner cylinder 7;

[0030] When in use, the inner cylinder 7 and the outer cover 6 arranged outside the door lock body 14 can effectively protect the door lock body 14, avoid the door lock from being damaged due to damp and rust, and ensure the normal use of the door lock.

[0031] In the embodiment two, the movable door 1 is rotatably connected to the box body 3, and the movable door 1 is provided with two groups. An observation window is arranged on the surface of the movable door 1 located at the upper half of the box body 3, and a transparent glass 2 is fixed in the observation window. When in use, the observation window and the transparent glass 2 arranged in the observation window facilitate the operator to observe the inside of the box body 3 through the transparent glass 2.

[0032] A plurality of equidistant linearly distributed heat dissipation grooves 5 are arranged on the side wall of the box body 3, and a protective cover 4 is fixed at each heat dissipation groove 5. When in use, the heat dissipation grooves 5 facilitate heat dissipation of the inside of the box body 3, and the protective cover 4 arranged above the heat dissipation grooves 5 avoids foreign matters from directly entering the inside of the box body 3 through the heat dissipation grooves 5.

[0033] In the embodiment three, the vertical plates 11 are located below the door lock body 14, and the two groups of vertical plates 11 are symmetrically distributed about the central axis of the door lock body 14. The two groups of connecting rods 12 are symmetrically distributed about the central axis of the rotating shaft 10. A groove 16 is arranged on the surface of the movable door 1, the groove 16 is in the form of a ring, the groove 16 is located at the periphery of the door lock body 14, and the insertion ring 18 is inserted into the groove 16. When the outer cover 6 is arranged outside the door lock body 14, the insertion ring 18 is directly inserted into the groove 16 first, the outer cover 6 and the movable door 1 are connected, and the stability of the outer cover 6 is improved.

[0034] The bottom wall of the bottom ring 13 is in contact with and abuts against the surface of the movable door 1, and the material of the bottom ring 13 is rubber. When the insertion ring 18 is inserted into the groove 16, the rubber material of the bottom ring 13 will continuously approach the movable door 1 and then be in contact with and abut against the surface of the movable door 1, the waterproof performance of the outer cover 6 is improved, and the protection performance of the door lock body 14 is improved.

[0035] The inner thread 17 and the outer thread 15 are matched with each other. The transmission rod 9 is fixed at the center of the surface of the inner cylinder 7, and two groups of side ears 8 are fixed on the surface of the transmission rod 9. The rubber ring 19 is fixed at the top periphery of the inner cylinder 7 and is in contact with the top of the outer cover 6. When in use, the transmission rod 9 and the side ears 8 thereon are designed to facilitate the operator to install and adjust. After the inner cylinder 7 and the door lock body 14 are connected, the sealing ring 19 is arranged to contact the outer cover 6, so as to avoid rainwater from entering between the inner cylinder 7 and the outer cover 6 and improve the sealing performance.

[0036] It is worth noting that: when installing, the inner cylinder 7 needs to be away from the bottom of the outer cover 6, so that the inner cylinder 7 and the lock body 14 are on the same horizontal line after the outer cover 6 abuts against the movable door 1, and the subsequent stable butt joint of the inner thread 17 and the outer thread 15 is ensured.

[0037] In actual use, the inner cylinder 7 and the outer cover 6 arranged outside the lock body 14 can effectively protect the lock body 14, avoid damage caused by damp and rust of the lock, ensure normal use of the lock, thereby improving the overall reliability and service life of the grid-connected box. When the lock body 14 needs to be used, the inner cylinder 7 and the outer cover 6 need to be removed, and the specific operation is as follows: the inner cylinder 7 is rotated by manually holding and rotating the two groups of side ears 8, thereby driving the transmission rod 9 and the inner cylinder 7 to rotate, so as to realize the disengagement of the inner cylinder 7 and the lock body 14. In this process, the outer wall of the inner cylinder 7 is synchronously connected with the outer cover 6 in a threaded manner, the outer cover 6 is stable, and the movement of the inner cylinder 7 is realized. By rotating the connecting rod 12, the inner cylinder 7 and the outer frame are rotated to below the vertical plate 11, connected with the movable door 1, and lost. When the inner cylinder 7 and the outer cover 6 need to be installed, the specific operation is as follows: first, rotate the side ears 8 to move the inner cylinder 7 away from the bottom of the outer cover 6, rotate the connecting rod 12 to drive the inner cylinder 7 and the outer cover 6 to rotate, so that the outer cover 6 continuously approaches the movable door 1, and then the insertion ring 18 is inserted into the groove 16, the bottom ring 13 contacts and abuts against the movable door 1. At this time, by rotating the side ears 8, the inner cylinder 7 is driven to rotate, and under the action of the outer thread 15 and the inner thread 17, the inner cylinder 7 is installed on the lock body 14. The outer cover 6 and the inner cylinder 7 are arranged outside the lock body 14, thereby realizing protection of the lock body 14. Thus, the problem that the existing grid-connected box structure has a lock arranged on the movable door 1 of the grid-connected box for locking the movable door 1, and the front end of the lock is exposed for a long time, which causes the lock to be easily damp and rusty during the rainy season, thereby affecting normal use, is avoided.

[0038] Although the embodiments of the present application have been shown and described, it should be understood by those skilled in the art that various changes, modifications, replacements and modifications can be made to these embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
