Description

Technical Field

[0001] This utility model relates to the field of instrument technology, and more specifically, to a multifunctional instrument with a protective structure. Background Technology

[0002] The protective structure is designed to protect multifunction instruments from damage caused by the external environment. In industrial environments, multifunction instruments may face harsh conditions such as high temperatures, high humidity, and high dust levels. The protective structure effectively isolates these adverse factors, ensuring the normal operation of the instrument. Furthermore, the protective structure prevents damage from physical impacts, thereby extending the instrument's service life.

[0003] In existing publicly available literature, patent publication number CN215297532U discloses a liquid crystal multi-functional power meter with a protective shell structure. This multi-functional meter, when impacted, causes the anti-collision plate and connecting plate to simultaneously retract and buffer, preventing deformation at the connection between the anti-collision plate and the shock-absorbing column and tilting of the sliding rod. This ensures the sliding rod and the sliding barrel remain parallel, allowing the sliding rod to smoothly enter the sliding barrel and ensuring the spring can contract effectively, thus extending the service life of the protective shell and reducing maintenance costs. However, this multi-functional meter has the following problems.

[0004] When a multi-function instrument is in use, it is protected by an external device. However, the protection process requires operation of the instrument, and the operator must close the protective housing during operation. If the housing is not closed in time, the instrument may be damaged by an external impact, making it difficult to achieve automatic protection. Therefore, a multi-function instrument with a protective structure is needed. Utility Model Content

[0005] To overcome the aforementioned deficiencies of the prior art, this utility model provides the following technical solution: a multifunctional instrument with a protective structure, comprising an instrument housing, a display screen, and a top shell. The display screen is fixed to the inner wall of the instrument housing, and the top shell is located above the instrument housing. The inner wall of the top shell is provided with a lowering protection mechanism. The lowering protection mechanism includes a transparent shell fixedly disposed on the inner wall of the top shell, and a support column is fixedly installed at the top of the top shell. A limit ring is fixedly connected to the outer wall of the support column, and a limit block is fixedly installed at the top of the support column. A guide sleeve is fixedly connected to one side of the top shell, and a guide post is slidably connected to the inner wall of the guide sleeve. A support block is fixedly connected to the bottom end of the guide post, and the support block is fixedly connected to the instrument housing. A rubber pad is adhered to the upper surface of the instrument housing.

[0006] Preferably, the top shell is made of carbon fiber, the limiting ring has a circular cross-sectional shape, and the outer wall of the support column is smooth. The outer wall of the guide column and the inner wall of the guide sleeve block are smooth surfaces, and the top of the guide column has a polygonal cross-sectional shape. A mounting column is fixedly connected to the bottom of the instrument housing, and a mounting base is welded to the bottom of the mounting column, which supports the mounting column. A connecting block is provided below the support block, and the connecting block is fixedly connected to the instrument housing. A reinforcing column is fixedly installed on one side of the connecting block, and a mounting plate is fixedly connected to one end of the reinforcing column.

[0007] In this technical solution, bolts are inserted into the mounting base to achieve fixed installation. The mounting column supports the instrument housing, increasing its stability. The hand grips the outer wall of the support column, which moves the top shell upwards, which in turn moves the transparent shell upwards. The guide sleeve moves upwards along the outer wall of the guide column, allowing operation on the instrument housing. After operation, the support column can be released. Under gravity, the top shell moves the guide sleeve downwards, supporting the guide column. The top of the inner wall of the top shell then contacts the rubber pad, providing cushioning during operation.

[0008] Preferably, the outer wall of the mounting column is provided with a limiting support assembly; the limiting support assembly includes a support rod fixedly disposed on one side of the outer wall of the mounting column, and an arc-shaped strip is fixedly connected to one end of the support rod. Arc-shaped blocks are fixedly connected to both ends of the arc-shaped strip, and an arc-shaped pad is adhered to the upper surface of each arc-shaped block. The two arc-shaped blocks are symmetrically arranged about the arc-shaped strip, and both arc-shaped pads are made of rubber.

[0009] In this technical solution, a column support rod is installed, an arc-shaped strip supports two arc-shaped blocks, and the two arc-shaped blocks support two arc-shaped pads respectively, so that the arc-shaped pads can limit the bottom end of the transparent shell.

[0010] The technical effects and advantages of this utility model are as follows:

[0011] This utility model adopts a downward protection mechanism. The hand is held on the outer wall of the support column. The hand can be limited by the limiting ring and the limiting block. The support column drives the top shell to move upward, and the guide sleeve block moves upward along the outer wall of the guide column. Operation can be performed on the instrument shell. After the operation is completed, the support column can be released. The top shell drives the guide sleeve block to move downward, and the guide sleeve block slides down along the outer wall of the guide column. The rubber pad buffers the operation of the top shell. The top shell and the transparent shell can automatically protect the outer wall of the instrument shell.

[0012] 2. This utility model adopts a limiting support component, which supports the support rod by installing the column, the support rod supports the arc strip, the arc strip supports two arc blocks, and the arc pad can limit the bottom of the transparent shell and play a buffer protection role for the transparent shell.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] As attached Figure 1 - Appendix Figure 5 The invention relates to a multi-functional instrument with a protective structure. The instrument is equipped with a lowering protection mechanism. The lowering protection mechanism can buffer the top shell 3 through the rubber pad 11. The top shell 3 and the transparent shell 4 can automatically protect the outer wall of the instrument shell 1. The specific structure of the lowering protection mechanism is as follows.

[0021] In this embodiment, as shown in the appendix Figure 1 - Appendix Figure 3As shown, the display screen 2 is fixed to the inner wall of the instrument housing 1, and the top shell 3 is located above the instrument housing 1. The inner wall of the top shell 3 is provided with a lowering protection mechanism. The lowering protection mechanism includes a transparent shell 4 fixedly installed on the inner wall of the top shell 3, and a support column 5 is fixedly installed at the top of the top shell 3. A limit ring 6 is fixedly connected to the outer wall of the support column 5, and a limit block 7 is fixedly installed at the top of the support column 5. A guide sleeve 8 is fixedly connected to one side of the top shell 3, and a guide post 9 is slidably connected to the inner wall of the guide sleeve 8. A support block 10 is fixedly connected to the bottom end of the guide post 9, and the support block 10 is fixedly connected to the instrument housing 1. A rubber pad 11 is adhered to the upper surface of the instrument housing 1. The outer wall of the guide post 9 and the inner wall of the guide sleeve 8 are smooth surfaces, and the cross-sectional shape of the top of the guide post 9 is polygonal.

[0022] In this embodiment, as shown in the appendix Figure 2 - Appendix Figure 4 As shown, a mounting column 12 is fixedly connected to the bottom of the instrument housing 1, and a mounting base 13 is welded to the bottom of the mounting column 12. The mounting base 13 is used to support the mounting column 12 so that bolts can be inserted into the mounting base 13 to fix the mounting base 13. The mounting base 13 supports the mounting column 12, and the mounting column 12 supports the instrument housing 1. A connecting block 14 is provided below the support block 10. The connecting block 14 is fixedly connected to the instrument housing 1. A reinforcing column 15 is fixedly installed on one side of the connecting block 14, and a mounting plate 16 is fixedly connected to one end of the reinforcing column 15 so that bolts can be inserted into the holes of the mounting plate 16. After the mounting plate 16 is fixed, it can provide support for the reinforcing column 15. The reinforcing column 15 supports the connecting block 14 and increases the stability of the connecting block 14.

[0023] In this embodiment, the multifunctional instrument with a protective structure is used by inserting bolts into the holes of the mounting plate 16. After the mounting plate 16 is fixed, it provides support for the reinforcing column 15. The reinforcing column 15 supports the connecting block 14, increasing the stability of the connecting block 14. The connecting block 14 supports the instrument housing 1. The instrument housing 1 then supports the display screen 2, which can display specific instrument data and serves as a display function.

The hand is held on the outer wall of the support column 5, and the hand can be limited by the limiting ring 6 and the limiting block 7. The support column 5 drives the top shell 3 to move upward, the top shell 3 drives the transparent shell 4 to move upward, and the top shell 3 drives the guide sleeve 8 to move upward. The guide sleeve 8 moves upward along the outer wall of the guide column 9. The instrument shell 1 supports the support block 10, and the support block 10 supports the guide column 9, increasing the stability of the guide column 9.

[0024] This allows operation to be performed on the instrument housing 1. After the operation is completed, the support column 5 can be released. Under the action of gravity, the top shell 3 moves the guide sleeve 8 downward. The guide sleeve 8 slides down along the outer wall of the guide column 9 and is supported by the support block 10. In this way, the top of the inner wall of the top shell 3 contacts the rubber pad 11, and the rubber pad 11 provides cushioning for the top shell 3. Thus, when the operator moves away from the instrument housing 1, the outer wall of the instrument housing 1 can be protected by the top shell 3 and the transparent shell 4.

[0025] In this embodiment, as shown in the appendix Figure 5 As shown, the outer wall of the mounting column 12 is provided with a limiting support assembly; the limiting support assembly includes a support rod 17 fixedly installed on one side of the outer wall of the mounting column 12, and an arc-shaped strip 18 is fixedly connected to one end of the support rod 17. Arc-shaped blocks 19 are fixedly connected to both ends of the arc-shaped strip 18, and an arc-shaped pad 20 is adhered to the upper surface of each arc-shaped block 19. The two arc-shaped blocks 19 are symmetrically arranged about the arc-shaped strip 18, and the two arc-shaped pads 20 are both made of rubber.

[0026] In this embodiment, the multifunctional instrument with a protective structure is used by mounting column 12 supporting support rod 17, support rod 17 supporting arc strip 18, arc strip 18 supporting two arc blocks 19, and the two arc blocks 19 supporting two arc pads 20 respectively, so that the arc pads 20 can limit the bottom end of the transparent shell 4, thus providing a buffer protection for the transparent shell 4.
