Description

Technical Field

[0001] This utility model belongs to the field of instrument protection technology, and in particular relates to an instrument protection device. Background Technology

[0002] Instruments are widely used in many fields such as industrial production and scientific research to measure and display various physical quantities. The normal operation and accurate reading of instruments are crucial, and the instrument cover, as an important component, plays a protective role.

[0003] Regarding the above-mentioned and existing related technologies, the inventor believes that the following defects often exist: Traditional instrument covers only provide simple protection for instruments by rotating them open or blocking them. External dust particles and moisture molecules can easily enter the instrument through the tiny gaps between the cover and the instrument body. Over time, dust and stains will gradually accumulate on the instrument surface, which not only affects the clarity of the readings but also reduces the accuracy and efficiency of the operator in reading data. Therefore, an instrument cover is proposed to address the above problems. Utility Model Content

[0004] The purpose of this invention is to solve the problems existing in the prior art and to propose an instrument protection device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an instrument protection device, comprising an instrument body, characterized in that: a first slide is fixed to one side of the upper surface of the instrument body, and a second slide is fixed to the other side; round rods are fixedly connected to the inner walls of both the first and second slides; sliders are slidably connected to the two round rods; springs are sleeved on the round rods at both ends of the sliders; a protective cover is fixedly connected between the two sliders; the protective cover slides between the first and second slides via the sliders, thereby opening and closing the protective cover on the surface of the instrument body; a first component is provided on the first slide to fix the protective cover after it is opened, and a second component is provided on the second slide to seal and fix the protective cover after it is closed.

[0006] Furthermore, the first component includes a drive rod, which is fixed to the upper surface of the first carriage, and a first L-shaped plate is threaded onto the drive rod; after the protective cover is opened, the first L-shaped plate rotates around the drive rod as an axis, so that the first L-shaped plate presses against the surface of the protective cover, thereby fixing the protective cover after it is opened.

[0007] Furthermore, the second component includes a threaded rod, which is fixed on the second carriage, and a second L-shaped plate is threadedly connected to the threaded rod; after the protective cover is closed, the second L-shaped plate rotates about the threaded rod as an axis, so that the second L-shaped plate abuts against the surface of the protective cover, thereby sealing and fixing the protective cover after it is closed.

[0008] Furthermore, a sealing gasket is provided on the lower surface of the protective cover.

[0009] Furthermore, the spring on the round rod fitted inside the first slide is fixed at one end to the slider and connected to the first slide at the other end; the spring on the round rod fitted inside the second slide is fixed at one end to the slider and connected to the second slide at the other end.

[0010] Furthermore, a mounting ring adapted to the protective cover is fixed on the lower surface of the protective cover. A sponge cleaning pad is provided inside the mounting ring. Two threaded holes are opened on the mounting ring. Bolts are inserted into the threaded holes to fix the sponge cleaning pad. The bolt fixing method facilitates the periodic replacement of the sponge cleaning pad.

[0011] Furthermore, the protective cover has two U-shaped blocks symmetrically arranged on its surface for gripping.

[0012] The beneficial effects of this utility model are as follows: the overall structure is simple and easy to use. During the opening or closing of the cover, the sponge cleaning pad can be driven to wipe and clean the surface of the instrument body, which plays a protective and sealing role on the surface of the instrument body, preventing dust, water vapor, oil and other impurities from entering the interior of the instrument body through the cover. This avoids these impurities from causing pollution, corrosion or wear to sensitive components of the instrument body such as sensors, circuit boards, and mechanical transmission devices, thereby ensuring the measurement accuracy and stability of the instrument body, extending the service life of the instrument, and keeping the appearance of the instrument body clean and beautiful, making it easy for operators to observe and read the instrument readings.

[0020] See Figure 1-6 As shown, an instrument protection device includes an instrument body 1, characterized in that: a first slide 3 is fixed to one side of the upper surface of the instrument body 1, and a second slide 16 is fixed to the other side; round rods 4 are fixedly connected to the inner walls of both the first slide 3 and the second slide 16; sliders 5 are slidably connected to the two round rods 4; springs 2 are sleeved on the round rods 4 at both ends of the sliders 5; a protective cover 6 is fixedly connected between the two sliders 5; the protective cover 6 slides between the first slide 3 and the second slide 16 via the sliders 5, thereby opening and closing the protective cover 6 on the surface of the instrument body 1; a first component is provided on the first slide 3 to fix the protective cover 6 after it is opened; and a second component is provided on the second slide 16 to seal and fix the protective cover 6 after it is closed.

[0021] The first component includes a drive rod 13, which is fixed to the upper surface of the first slide 3. A first L-shaped plate 14 is threaded onto the drive rod 13. After the protective cover 6 is opened, the first L-shaped plate 14 rotates around the drive rod 13, causing the first L-shaped plate 14 to press against the surface of the protective cover 6, thereby fixing the protective cover 6 after it is opened.

[0022] The second component includes a threaded rod 7, which is fixed on the second slide 16. A second L-shaped plate 8 is threadedly connected to the threaded rod 7. After the protective cover 6 is closed, the second L-shaped plate 8 rotates around the threaded rod 7 as an axis, so that the second L-shaped plate 8 abuts against the surface of the protective cover 6, thereby sealing and fixing the protective cover 6 after it is closed.

[0023] The lower surface of the protective cover 6 is provided with a sealing gasket 9.

[0024] A spring 2, fitted inside the first slide 3, is attached to the round rod 4 at one end and fixed to the slider 5 at the other end, connected to the first slide 3. A spring 2, fitted inside the second slide 16, is also attached to the round rod 4 at one end and fixed to the slider 5 at the other end, connected to the second slide 16. When the protective cover 6 needs to be closed, the spring 2 will cause the slider 5 to automatically spring back on the round rod 4, thereby automatically returning the protective cover 6 to its original position, improving the convenience of the device.

[0025] The lower surface of the protective cover 6 is fixed with a mounting ring 10 that is compatible with the protective cover 6. The mounting ring 10 is provided with a sponge cleaning pad 11. The mounting ring 10 has two threaded holes. The bolt 12 is inserted into the threaded holes to fix the sponge cleaning pad 11. The bolt 12 fixing method facilitates the periodic replacement of the sponge cleaning pad 11.

[0026] The protective cover 6 has two U-shaped blocks 15 symmetrically arranged on its surface for gripping.

[0027] Working principle:

[0028] When it is necessary to protect the instrument body 1, push the U-shaped block 15 to drive the protective cover 6 and the sealing gasket 9 together to drive the slider 5 to slide on the round rod 4, and at the same time drive the mounting ring 10 to move. The sponge cleaning pad 11 on the mounting ring 10 cleans the instrument body 1 until the protective cover 6 completely covers the surface of the instrument body 1. Then push the second L-shaped plate 8 to rotate around the threaded rod 7 until the second L-shaped plate 8 abuts against the surface of the protective cover 6.

[0029] When it is necessary to open the protective cover 6 to view the instrument, push the second L-shaped plate 8 to rotate on the surface of the threaded rod 7 until the second L-shaped plate 8 moves away from the surface of the protective cover 6. At this time, the U-shaped block 15 can be pushed to make the protective cover 6 slide. The cleaning pad 11 cleans the instrument body 1 again until the protective cover 6 no longer blocks the surface of the instrument body 1. At this time, the first L-shaped plate 14 can be rotated on the arc surface of the screw 12 until the first L-shaped plate 14 abuts against the surface of the protective cover 6. Then the operator can observe the parameters of the instrument body 1.
