Description

Technical Field

[0001] The utility model relates to the technical field of protective shells, in particular to an anti-fall shell. Background Art

[0002] Power quality is crucial to the safe production, economic benefits, and livelihoods of industrial and utility users. This is particularly true in photovoltaic power generation, where AC / DC inverters are used. These inverters convert DC power to AC power through the on-and-off switching of semiconductor power switches, generating harmonics. Uncertainty in photovoltaic power generation systems causes random fluctuations in output power, leading to grid frequency deviations, voltage fluctuations, and flicker. This is where power quality analyzers play a crucial role. With the development of power quality analyzers, a flat-panel model has emerged.

[0003] To protect a flat-panel power quality analyzer, a protective housing is typically placed on the outside of the analyzer. While the existing protective housing can protect the four corners and bottom plate of the analyzer, it lacks protection for the display screen, which can easily damage the display screen when not in use, causing it to crack or become scratched. Utility Model Content

[0004] In view of this, the purpose of the present invention is to provide a drop-proof housing to solve the technical problem that the display screen of a flat-panel power quality analyzer is easily damaged when not in use, causing the display screen to be cracked or full of scratches.

[0006] A drop-proof shell includes a protective shell body that covers the outside of a flat-panel power quality analyzer and is used to protect the four corners and bottom of the flat-panel power quality analyzer. The protective shell body is a box-shaped structure with an open top. A plate-shaped protective plate is movably connected to the protective shell body. The top opening of the protective shell body is closed or opened by flipping the protective plate.

[0007] Furthermore, the guard plate is provided with a first connecting piece, and the protective shell body is provided with a second connecting piece that cooperates with the first connecting piece.

[0008] Furthermore, a first protective pad is provided on the guard plate for cushioning and protecting the display screen of the flat-panel power quality analyzer. The first protective pad is made of a flexible material. When the guard plate is covered on the protective shell body, the first protective pad abuts against the display screen of the flat-panel power quality analyzer.

[0009] Furthermore, a second protective pad is provided on the inner wall of the protective shell body for buffering and protecting the flat-panel power quality analyzer. The outer wall of the second protective pad is bonded to the inner wall of the protective shell body by adhesive, and the second protective pad is made of flexible material.

[0010] Furthermore, the top of the second protective pad extends horizontally inward to form a limiting portion for limiting the flat-plate power quality analyzer in the protective shell body, and the bottom of the limiting portion abuts against the top of the flat-plate power quality analyzer. The limiting portion is made of flexible material.

[0011] Furthermore, a plurality of heat dissipation holes communicating with the interior of the protective shell body are provided at the bottom of the protective shell body.

[0012] Furthermore, a handheld component is provided on the protective shell body.

[0013] Furthermore, a supporting component is movably connected to the bottom of the protective shell body, and an abutment portion for limiting the position of the free end of the supporting component is provided on the side of the guard plate facing away from the first connecting member. The supporting component is abutted against the abutment portion at one end away from the protective shell body so that the supporting component supports the protective shell body, thereby tilting the flat-panel power quality analyzer.

[0014] Furthermore, the abutting portion is a tooth-shaped groove, and there are multiple tooth-shaped grooves, which are distributed in an array along the width direction of the guard plate.

[0015] Furthermore, the support component is a plate-shaped structure, the width direction of the support component is consistent with the length direction of the toothed groove, the support component is provided with a third connecting member on one side relative to the bottom of the protective shell body, and the bottom of the protective shell body is provided with a fourth connecting member that cooperates with the third connecting member.

[0016] The beneficial effects of the present invention are:

[0017] The anti-drop shell is provided with a protective plate. When the protective plate is flipped over and covered on the protective shell body, the protective plate can protect the display screen of the flat-panel power quality analyzer, thereby reducing the possibility of cracking and scratching of the display screen, and further improving the protection of the flat-panel power quality analyzer.

[0032] See also Figure 1-7 The utility model provides a technical solution: a drop-proof shell, including a protective shell body 1 that covers the outside of a flat-panel power quality analyzer 17 and is used to protect the four corners and the bottom of the flat-panel power quality analyzer 17. The protective shell body 1 is a box-shaped structure with an open top. A plate-shaped protective plate 2 is movably connected to the protective shell body 1. The top opening of the protective shell body 1 can be closed or opened by flipping the protective plate 2.

[0033] The design of the open box-shaped structure at the top of the protective shell body 1 facilitates the placement and removal of the flat-panel power quality analyzer 17. After the flat-panel power quality analyzer 17 is placed in the protective shell body 1, the four corners and the bottom of the flat-panel power quality analyzer 17 can be protected, reducing damage to the flat-panel power quality analyzer 17 caused by external forces. The protective shell body 1 is also provided with a connection hole 3 for passing the external plug of the flat-panel power quality analyzer 17. The external plug can be connected to the connector of the flat-panel power quality analyzer 17 through the connection hole 3. A plate-shaped protective plate 2 is movably connected to the protective shell body 1. The top opening of the protective shell body 1 is closed or opened by flipping the protective plate 2 to protect the display screen of the flat-panel power quality analyzer 17.

[0034] The movable connection between the guard plate 2 and the protective shell body 1 can be specifically hinged, or the protective shell body 1 and the guard plate 2 can be connected together by a flexible belt or linear structure, or other connection methods that can achieve the flipping of the guard plate 2 and thus close the opening of the protective shell body 1. In this embodiment, a connecting plate 4 is specifically provided between the guard plate 2 and the side wall of the protective shell body 1. One side of the connecting plate 4 is hinged to the protective shell body 1, and the other side is connected to the guard plate 2 via a flexible connection portion 5. The hinged connection between the connecting plate 4 and the protective shell body 1 enables the rotation of the guard plate 2. The flexible connection portion 5 enables the guard plate 2 to be further rotated after the connecting plate 4 is blocked by the side of the protective shell body 1, thereby achieving the flipping of the guard plate 2.

[0035] The specific model of the flat-panel power quality analyzer 17 is KGZW-130.

[0036] When in use, first place the protective shell body 1 flat on the table or the ground, then place the flat-panel power quality analyzer 17 into the protective shell body 1, and then flip the protective plate 2 so that the protective plate 2 covers the protective shell body 1, thereby protecting the display screen of the flat-panel power quality analyzer 17, reducing the possibility of cracking and scratching the display screen, and further improving the protection of the flat-panel power quality analyzer 17.

[0037] When the flat-panel power quality analyzer 17 is needed, the protective plate 2 only needs to be turned over to expose the display screen so that subsequent staff can operate on the display screen.

[0038] In this embodiment, the guard plate 2 is provided with a first connecting member 6 , and the protective shell body 1 is provided with a second connecting member 7 that cooperates with the first connecting member 6 .

[0039] The first connecting member 6 and the second connecting member 7 can adopt existing buckle or lock connection methods. In this embodiment, the first connecting member 6 is a first magnetic piece embedded in one side of the protective plate 2. When the protective plate 2 is covered on the protective shell body 1, the first magnetic piece faces the protective shell body 1. The second connecting member 7 is a second magnetic piece embedded in the upper end of the protective shell body 1. When the protective plate 2 is covered on the protective shell body 1, the first magnetic piece and the second magnetic piece overlap. The first magnetic piece and the second magnetic piece have opposite magnetic poles. The first magnetic piece and the second magnetic piece are attracted together, thereby fixing the protective plate 2 to the protective shell body 1.

[0040] In this embodiment: a first protective pad 8 is provided on the protective plate 2 for buffering and protecting the display screen of the flat-panel power quality analyzer 17. The first protective pad 8 is made of a flexible material. When the protective plate 2 is covered on the protective shell body 1, the first protective pad 8 abuts against the display screen of the flat-panel power quality analyzer 17.

[0041] The first protective pad 8 is a plate-like structure, laid on one side of the protective plate 2 and fixed with adhesive. The first protective pad 8 is made of a flexible material such as rubber or sponge. The first protective pad 8 provides additional cushioning protection for the display screen, further reducing the impact of external impact on the display screen.

[0042] In this embodiment, a second protective pad 9 is provided on the inner side wall of the protective shell body 1 for buffering and protecting the flat-panel power quality analyzer 17. The outer side wall of the second protective pad 9 is bonded to the inner side wall of the protective shell body 1 by adhesive. The second protective pad 9 is made of flexible material.

[0043] The second protective pad 9 is an annular structure, and is attached to the inner wall of the protective shell body 1. The first protective pad 8 is fixed to the inner wall of the protective shell body 1 by adhesive. By providing the second protective pad 9, the flat-panel power quality analyzer 17 is further protected.

[0044] In this embodiment: the top of the second protective pad 9 extends horizontally inward to form a limiting portion 10 for limiting the flat-plate power quality analyzer 17 in the protective shell body 1, and the bottom of the limiting portion 10 is against the top of the flat-plate power quality analyzer 17. The limiting portion 10 is made of a flexible material.

[0045] Specifically, the limiting portion 10 is a ring-shaped structure. By providing the limiting portion 10 , the movement of the flat-panel power quality analyzer 17 in the protective housing body 1 can be restricted, thereby reducing the possibility of the flat-panel power quality analyzer 17 shaking or falling off.

[0046] In this embodiment, a plurality of heat dissipation holes 11 communicating with the interior of the protective shell body 1 are formed at the bottom of the protective shell body 1 .

[0047] By using the heat dissipation through-hole 11 as a heat dissipation structure of the flat-plate power quality analyzer 17 , the analyzer can dissipate heat well during operation, thereby reducing the possibility of overheating damage.

[0048] In this embodiment, a hand-held component 12 is provided on the protective shell body 1 .

[0049] The handheld component 12 is an arc-shaped handle, and both ends of the handheld component 12 are fixedly connected to the outer wall of the protective shell body 1 close to the second connecting member 7. By providing the handheld component 12, it is easy to carry and move the flat-panel power quality analyzer 17, thereby improving the convenience of use.

[0050] In this embodiment: a support component 13 is movably connected to the bottom of the protective shell body 1. Specifically, the support component 13 is hinged to the bottom of the protective shell body 1, and an abutment portion 14 for limiting the position of the free end of the support component 13 is provided on the side of the guard plate 2 facing away from the first connecting member 6. By abutting the end of the support component 13 away from the protective shell body 1 against the abutment portion 14, the support component 13 supports the protective shell body 1, thereby tilting the flat-panel power quality analyzer 17. After the flat-panel power quality analyzer 17 is placed on the desktop, the flat-panel power quality analyzer 17 is tilted at a certain angle, making it easier for the operator to read the data on the display screen and to operate the display screen.

[0051] In this embodiment, the abutting portion 14 is a tooth-shaped groove, and there are multiple tooth-shaped grooves, which are distributed in an array along the width direction of the guard plate 2.

[0052] By specifically setting the abutment portion 14 as a tooth-shaped groove, and distributing a plurality of tooth-shaped grooves in an array along the width direction of the guard plate 2, when the support component 13 abuts against the tooth-shaped grooves at different positions, the flat-panel power quality analyzer 17 has different inclination angles, so that the support angle can be adjusted according to different users.

[0053] In this embodiment: the support component 13 is a plate-shaped structure, the width direction of the support component 13 is consistent with the length direction of the toothed groove, the support component 13 is provided with a third connecting member 15 on one side relative to the bottom of the protective shell body 1, and the bottom of the protective shell body 1 is provided with a fourth connecting member 16 that cooperates with the third connecting member 15.

[0054] The third connector 15 and the fourth connector 16 can be connected using existing buckle or lock methods. In this embodiment, the third connector 15 is a third magnetic piece disposed on the side of the support member 13 relative to the bottom of the protective shell body 1, and the fourth connector 16 is a fourth magnetic piece embedded in the bottom of the protective shell body 1. The third and fourth magnetic pieces have opposite magnetic poles. The third and fourth magnetic pieces are attracted together to secure the support member 13 to the protective shell body 1, facilitating storage of the support member 13 and reducing obstruction caused by the support member 13 during transfer of the device.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
