Description

Technical Field

[0002] Photovoltaic meter boxes usually refer to electric energy metering equipment used to monitor and manage photovoltaic power generation systems. When some photovoltaic boxes are in use, in order to prevent the box from being damaged by external impact, a layer of protective plate will be installed on the outer wall of the box. However, some protective box plates are installed with multiple sets of bolts, which makes it too troublesome for workers to disassemble and install, and the practicality is too low.

[0003] After searching, Chinese patent announcement number: CN220605346U discloses a protective box plate for an electric meter box, including a box body, a box cover, a protective outer plate, a protective inner plate, and a plurality of dampers, the damper is used to connect the protective outer plate and the protective inner plate and is fixed on the side plate of the box body, and an anti-slip unit is arranged at one end of the damper placed in the box body, and the anti-slip unit has a preset structure that can be retracted and reset when squeezed, so that when the protective inner plate is combined with the damper along the installation direction, the anti-slip unit is squeezed and retracted and is not in the moving path of the protective inner plate, and when the protective inner plate is restored to the anti-slip state after passing, it abuts against the protective inner plate in the direction opposite to the installation direction of the protective inner plate. The beneficial effect of the utility model is that the protective inner plate and the damper can be quickly connected, and it is no longer necessary to tighten the connecting parts (fixed heads in the prior art) one by one, so that a tool-free and parts-free assembly mode is realized, which is suitable for quick and convenient assembly.

[0004] In the above technology, although there are certain improvements through the designed structure, there are still certain defects.

Since it is a prior art, it will not be described in detail in this case. A protective component 2 is provided on the right surface of the meter box body 1, and a blocking component 4 is provided on the lower surface of the right end of the protective component 2. A disassembly component 3 is provided on the right surface of the meter box body 1, and the protective component 2 includes a fixed shell 24, and the left surface of the fixed shell 24 contacts the right surface of the meter box body 1. When installing the protective component 2, it can be put on its outer wall from the lower side of the meter box body 1. This The protective component 2 can protect the front surface and left and right sides of the meter box 1, while the rear surface of part of the meter box 1 is connected to the wall or other buildings and does not need to be protected. The front surface of the fixed shell 24 is fixedly connected with a concave block 26, and the inner wall of the concave block 26 is rotatably connected with a rotating rod 27, and the outer wall of the rotating rod 27 is fixedly connected with a damping telescopic rod 28. The damping telescopic rod 28 is a prior art, which is a device for controlling structural vibration and shock absorption, and can be implemented by technicians in this field. Since it is a prior art, it will not be described in detail in this case. The front end of the damping telescopic rod 28 is hinged with a hinge block 29, and the right surface of the hinge block 29 is fixedly connected with a protective side plate 22, and the lower surface of the protective side plate 22 is provided with a rectangular groove 25.

[0033] Reference Figure 2 - Figure 3 , Figure 5The disassembly and assembly component 3 includes a fixing bar 31, which is fixedly connected to the right surface of the meter box 1. The fixing bar 31 slides on the inner wall of the fixing shell 24. The fixing bar 31 is set to a T shape, and a horizontal plate for blocking is provided at the top to prevent the fixing shell 24 from being pushed over during installation to ensure the stability of the connection. A rectangular groove 32 is opened on the front surface of the fixing bar 31.

[0034] Reference Figure 2 , Figure 4 The blocking assembly 4 includes a slider 42, which is slidably connected to the inner wall of the rectangular groove 25, and a spring 243 is fixedly connected to the rear surface of the slider 42. The spring 243 always pushes the slider 42 forward by its own elasticity to ensure the stability of the blocking block 41 limiting the sliding bar 23. The rear end of the spring 243 is fixedly connected to the inner wall of the rectangular groove 25, and a blocking block 41 is fixedly connected to the lower surface of the protective side plate 22. The inner wall of the front end of the blocking block 41 is rotatably connected to a roller 44. When the movable protective plate 21 is opened and closed, the roller 44 will roll on the rear surface of the sliding bar 23 to ensure the smoothness of the movable protective plate 21 when closing.

[0035] Reference Figure 2 - Figure 3 , Figure 5 The outer wall of the rotating rod 27 is sleeved with a torsion spring 210, which has a certain elasticity. It can buffer the external impact force through its own elasticity and ensure the stability of the protective component 2 when it is not subject to impact force. One end of the torsion spring 210 is fixedly connected to the inner wall of the rotating rod 27, and the other end of the torsion spring 210 is fixedly connected to the upper surface of the rear end of the damping telescopic rod 28. The inner wall of the front end of the protective side plate 22 is slidably connected with a sliding bar 23, and the front surface of the sliding bar 23 is fixedly connected with a movable protective plate 21. When the worker needs to inspect the meter box 1 when using the protective component 2, the blocking block 41 can be contacted to limit the sliding bar 23. At this time, the movable protective plate 21 will fall due to gravity, so that it can be opened, which is convenient for the worker to inspect the meter box 1, thereby improving practicality. The lower surface of the sliding bar 23 contacts the upper surface of the blocking block 41.

[0036] Reference Figure 2 - Figure 3 , Figure 5The disassembly and assembly component 3 also includes a block 33, the upper surface of the block 33 is set as an inclined surface to ensure the stability of its limit, the block 33 is slidably connected to the inner wall of the front end of the fixed shell 24, the front surface of the block 33 is fixedly connected with a pull rod 34, the pull rod 34 penetrates and is slidably connected to the front surface of the fixed shell 24, the rear surface of the block 33 contacts the inner wall of the rectangular groove 2 32, and the outer wall of the pull rod 34 is sleeved with a spring 1 35, the spring 1 35 always pulls the pull rod 34 to move backward through its own elasticity, to ensure the stability of the limit of the block 33 when the protective component 2 is in use, one end of the spring 1 35 is fixedly connected to the front surface of the fixed shell 24, one end of the spring 1 35 is fixedly connected to the front surface of the fixed shell 24, and the other end of the spring 1 35 is fixedly connected to the rear surface of the pull rod 34.

[0037] Working principle: When in use, when the protective component 2 needs to be installed, it is only necessary to push the fixed shell 24 from the bottom of the meter box 1 to the outer wall of the fixed bar 31. During the pushing process, the block 33 will contact the fixed bar 31. At this time, the fixed bar 31 will push it to move along the inclined surface of the block 33, and the block 33 will drive the pull rod 34 to move, and the pull rod 34 will stretch the spring 1 35 until the block 33 overlaps with the rectangular groove 2 32. At this time, the spring 1 35 will pull the pull rod 34 in the opposite direction through its own elasticity, and the block 33 will also move in the opposite direction and insert into the inner wall of the rectangular groove 2 32. In this way, the protective component 2 can be installed successfully. When disassembling, it is only necessary to pull the pull rod 34 to drive the block 33 to move away from the inner wall of the rectangular groove 2 32. In this way, the protective component 2 can be removed. It should be noted that when disassembling, make sure that the movable protective plate 21 is in the open state.

[0038] When in use, if the protective side plate 22 or the movable protective plate 21 is subjected to external impact force, the damping telescopic rod 28 will buffer the external impact force through its own damping characteristics, and at the same time, the front end of the damping telescopic rod 28 will rotate between the hinge block 29, and at the same time, its rear end will drive the rotating rod 27 to rotate on the inner wall of the concave block 26, and the torsion spring 210 will also rotate and deform accordingly. The torsion spring 210 will buffer the impact force through its own elasticity, thereby improving the buffering effect. At the same time, when the worker needs to open the movable protective plate 21 to inspect the meter box 1, he only needs to push the blocking block 41, and the blocking block 41 will drive the slider 42 to slide on the inner wall of the rectangular groove 1 25, and the slider 42 will squeeze the spring 2 43 until the blocking block 41 The upper surface of the sliding bar 23 does not contact the sliding bar 23. At this time, the movable protective plate 21 will move downward and open due to gravity, so that the blocking block 41 can be loosened, and the spring 2 43 will push the sliding block 42 to move in the opposite direction through its own elasticity, and the blocking block 41 will also move in the opposite direction to make the roller 44 contact with the sliding bar 23. When closing, the movable protective plate 21 can be pushed upward. At this time, the roller 44 will rotate on the inner wall of the front end of the blocking block 41, and at the same time, it will roll on the rear surface of the sliding bar 23 to ensure the smooth movement of the movable protective plate 21 until the sliding bar 23 moves to the upper side of the blocking block 41. At this time, the spring 2 43 will push the sliding block 42 to move in the opposite direction through its own elasticity, and the blocking block 41 will also move in the opposite direction to block the sliding bar 23 to prevent the movable protective plate 21 from falling.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
