Description

Technical Field

[0001] This utility model relates to the field of maintenance equipment technology, specifically to a portable precision instrument repair kit. Background Technology

[0002] In modern industry, scientific research, and medical fields, the application of precision instruments is becoming increasingly widespread. These instruments typically contain crucial components such as sophisticated optical elements, sensitive circuit boards, and high-precision sensors, requiring extremely high levels of cleanliness and stability in their working environment. However, when precision instruments malfunction, repair work often cannot be performed in dedicated cleanrooms and must, in most cases, be completed on-site or in a regular indoor environment. Repairing these instruments in such open environments presents two main technical challenges: First, there is the issue of environmental pollution. During maintenance, the instrument's outer casing is opened, exposing its core components directly to the ambient air. Suspended dust, particulate matter, and metal shavings or liquid splashes generated during maintenance can easily enter the instrument. Once these contaminants adhere to or deposit on the surface of precision components, they will directly affect their performance, such as reducing the light transmittance of the optical system, causing poor contact or short circuits in circuits, and accelerating wear on moving parts. This seriously affects the instrument's performance, measurement accuracy, and lifespan after maintenance, and may even cause secondary damage during the maintenance process.

[0003] Secondly, there is the challenge of balancing portability and functionality. To ensure repair quality, an ideal repair environment should be dustproof, anti-static, and shockproof. While existing technologies, such as fixed repair workbenches or large cleanroom cases, provide a good operating environment, their bulky size and complex structure fail to meet the urgent needs for portability and mobility of repair equipment in on-site, field, or rapid response scenarios. Common toolboxes on the market, while easy to carry, have limited functionality and lack the environmental isolation and purification capabilities necessary for precision instrument repair, thus failing to address contamination issues in open environments.

[0004] Therefore, there is an urgent need in this field for an innovative solution that can organically combine a clean and safe maintenance environment with portability and mobility. Specifically, it requires the design of a dedicated maintenance device that can effectively isolate external environmental pollution while being easy to carry and move, to ensure the safety and quality of precision instruments during various on-site maintenance operations. Utility Model Content

[0005] Based on this, it is necessary to provide a portable precision instrument repair box to address the problems of existing technologies. By setting an inclined double-layer transparent cover on the top of the box and opening an operating port for wearing rubber gloves on the side of the box, external air is drawn in by a fan, filtered by a filter on its outlet side, and then introduced into the hollow interlayer of the cover. It is then sent downward into the box through evenly distributed air outlets at the bottom of the cover. The airflow carries up the dust inside the box, which is then discharged from the exhaust port through a pressure valve. During the maintenance process, the inside of the box is always maintained at a positive pressure slightly higher than the outside atmosphere, effectively preventing external contaminants from entering. This solves the problem that precision instruments need to be repaired in a stable and dust-free environment.

[0006] To address the problems of existing technologies, this utility model provides a portable precision instrument repair box, comprising: a box body with an inclined window on the top, two operating ports on one side of the box body, rubber gloves extending into the box body installed in the operating ports, a drainage channel on the top of the box body, and an exhaust port at the bottom of the box body; a transparent cover plate located at the window of the box body, the transparent cover plate being hollow and having a rectangular array of air vents at the bottom, the two ends of the drainage channel being connected to the outside and the hollow layer of the transparent cover plate respectively; a drainage fan located in the drainage channel, with the air outlet side of the drainage fan facing the hollow layer of the transparent cover plate; in the maintenance state, the internal pressure of the box body is greater than atmospheric pressure; a filter screen located in the drainage channel cylinder and on the air outlet side of the drainage fan; and a pressure valve located at the exhaust port, when the internal pressure of the box body is greater than the opening threshold of the pressure valve, the gas inside the box body is discharged to the outside through the pressure valve.

[0007] Preferably, the window of the housing is provided with a hinge frame that is hinged thereto, and the housing is also provided with a buckle seat that is snapped together with the hinge frame. The transparent cover includes: an upper transparent plate, which is provided at the top of the hinge frame, and a lower transparent plate, which is provided at the bottom of the hinge frame. A hollow layer that communicates with the drainage channel is formed between the upper transparent plate and the lower transparent plate. A rectangular array of air outlets is on the lower transparent plate. A connecting groove that communicates with the hollow layer and the drainage channel is provided on the side of the hinge frame.

[0008] Preferably, four omnidirectional casters are provided on one side of the housing.

[0009] Preferably, a retractable pull rod is provided on one side of the box body.

[0010] Preferably, an open toolbox is provided on the inside of the box.

[0011] Preferably, the top of the toolbox is hinged to the inner wall of the box body so that the toolbox can be flipped upwards.

[0012] Preferably, the box is equipped with a folding arm, one end of which is rotatably connected to the inner wall of the box, and the other end of which is equipped with a magnifying glass.

[0013] Preferably, a supplementary light is provided at the top of the box.

[0014] Preferably, the exhaust port is located on the bottom side of the box body, and a perforated partition is provided at the bottom of the box body. Two downward inclined guide plates are provided at the bottom of the perforated partition, and a partition plate is provided between the two guide plates and the perforated partition. A collection chamber communicating with the exhaust port is formed between the guide plates and the ground inside the box body.

[0015] Compared with the prior art, the advantages of this application are as follows: By setting an inclined double-layer transparent cover on the top of the box and opening an operating port for wearing rubber gloves on the side of the box, external air is drawn in by the exhaust fan, filtered by the filter on its outlet side, and then introduced into the hollow interlayer of the cover. It is then sent downward into the box through the evenly distributed air blowing ports at the bottom of the cover. The airflow carries up the dust in the box and discharges it through the exhaust port with the air via the pressure valve. During the maintenance process, the box is always kept at a positive pressure slightly higher than the outside atmosphere, which effectively prevents external pollutants from entering, thus solving the problem that precision instruments need to be maintained in a stable and dust-free environment.

[0025] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0026] like Figures 1-5 As shown, a portable precision instrument repair kit includes: a box body 1 with an inclined window on the top, two operating ports 11 on one side of the box body 1, rubber gloves 12 extending into the box body 1 installed in the operating ports 11, a drainage channel 13 on the top of the box body 1, and an exhaust port 14 at the bottom of the box body 1; a transparent cover 2 located at the window of the box body 1, the transparent cover 2 being hollow and having a rectangular array of air vents 21 at the bottom, the two ends of the drainage channel 13 being connected to the outside and the hollow layer of the transparent cover 2 respectively; a drainage fan 3 located in the drainage channel 13, with the air outlet side of the drainage fan 3 facing the hollow layer of the transparent cover 2; in the maintenance state, the internal pressure of the box body 1 is greater than the atmospheric pressure; a filter screen 4 located in the drainage channel 13 and on the air outlet side of the drainage fan 3; and a pressure valve 5 located at the exhaust port 14, when the internal pressure of the box body 1 is greater than the opening threshold of the pressure valve 5, the gas inside the box body 1 is discharged to the outside through the pressure valve 5.

[0027] A portable precision instrument repair case includes a case body 1, a transparent cover 2, a ventilation fan 3, a filter 4, and a pressure valve 5. The top of the case body 1 has an inclined transparent cover 2 with a double-layered hollow structure. Air outlets 21 are evenly distributed at the bottom of the cover, creating a uniform downward airflow. An operating port 11 is provided on the side of the case body 1, equipped with rubber gloves 12 extending into the case, allowing operators to perform repairs without opening the case body 1. A ventilation channel 13 is also provided at the top of the case body 1. External air is drawn in by the ventilation fan 3, filtered by the filter 4 located on its outlet side, and then the clean air is introduced into the hollow interlayer of the transparent cover 2, and then delivered into the case body 1 through the air outlets 21. The airflow inside the case carries away dust generated during the repair process, which is then discharged through the pressure valve 5 at the bottom of the case body 1 from the exhaust port 14. Throughout the repair process, the inside of the case maintains a positive pressure slightly higher than the external atmosphere, effectively preventing external contaminants from entering and providing a stable and dust-free repair environment for precision instruments.

[0028] Pressure valve 5 consists of two rubber sheets located at exhaust port 14. When the internal pressure exceeds the elastic force of the rubber sheets, the two rubber sheets deform outward to create an air outlet.

[0029] External air is drawn into the drainage channel 13 by the drainage fan 3, filtered by the filter screen 4 to become clean air, and then enters the hollow interlayer of the transparent cover 2, and is evenly delivered into the chamber through the air outlet 21 at the bottom of the cover. The airflow forms a top-down flow in the chamber 1, carrying the suspended dust generated during maintenance to the bottom, and finally discharged by the pressure valve 5 at the exhaust port 14, so that the chamber is continuously maintained in a slightly positive pressure state.

[0030] This repair kit effectively isolates external contaminants by creating a stable internal positive pressure and dust-free airflow circulation, ensuring that precision instruments are maintained in a clean and stable environment during maintenance. Its compact structure and portability, along with the rubber gloves 12 equipped at the operating port 11, make maintenance work more convenient and prevent damage to the internal environment, thus improving the reliability and efficiency of on-site maintenance of precision instruments.

[0031] like Figure 6 and Figure 7 As shown, the window of the housing 1 is provided with a hinge frame 61 that is hinged to it, and the housing 1 is also provided with a buckle seat 62 that is snapped to the hinge frame 61. The transparent cover 2 includes: an upper transparent plate 22, which is provided at the top of the hinge frame 61, and a lower transparent plate 23, which is provided at the bottom of the hinge frame 61. A hollow layer that communicates with the drainage channel 13 is formed between the upper transparent plate 22 and the lower transparent plate 23. A rectangular array of air outlets is on the lower transparent plate 23. A connecting groove 611 that communicates with the hollow layer and the drainage channel 13 is provided on the side of the hinge frame 61.

[0032] The transparent cover 2 is connected to the window at the top of the housing 1 via a hinge frame 61. The hinge frame 61 is hinged to the edge of the window, allowing the entire cover to be opened or closed. The housing 1 has a latching seat 62 that mates with the hinge frame 61. When the cover is closed, it can be tightly locked using the latch, effectively ensuring the airtightness of the housing 1. The transparent cover 2 itself is composed of an upper transparent plate 22 and a lower transparent plate 23, both fixed to the hinge frame 61 and kept parallel, thus forming a sealed hollow interlayer. A connecting groove 611 is provided on the side of the hinge frame 61. When the cover is closed, this groove precisely aligns with the outlet of the drainage channel 13 on the housing 1, allowing filtered clean air to smoothly enter the hollow interlayer. The air inside the hollow interlayer is then stably delivered into the maintenance housing through air outlets 21 evenly distributed in a rectangular array on the lower transparent plate 23.

[0033] When the equipment is started, the clean airflow filtered by the filter screen 4 passes through the guide channel 13 and enters the hollow interlayer of the transparent cover plate 2 through the connecting groove 611 on the side of the hinge frame 61, continuously supplying clean air to the interior.

[0034] The hinged and snap-fit ​​structure facilitates the opening of the enclosure 1 for instrument loading and unloading and internal cleaning, while ensuring the airtightness of the enclosure 1 when closed, maintaining a stable micro-positive pressure environment inside. The evenly distributed air outlets 21 on the lower transparent plate 23 further ensure the uniformity and stability of the downward airflow, effectively preventing internal airflow disturbance or dust accumulation, and improving the overall cleanliness of the maintenance environment.

[0035] like Figure 2 As shown, four universal casters 63 are provided on one side of the housing 1.

[0036] Four omnidirectional casters 63 are located on the bottom side of the housing 1, a design that greatly enhances the portability and mobility of the repair kit. Operators can easily move the housing 1 to different work locations to adapt to diverse on-site maintenance needs.

[0037] like Figure 2 As shown, a telescopic pull rod 64 is provided on one side of the box body 1.

[0038] On the same side of the housing 1 where the universal casters 63 are installed, a retractable pull rod 64 is also provided. This design, together with the casters at the bottom, forms a complete portable mobility system, allowing the operator to easily and elegantly transport the repair case to any work location as needed, just like using a modern suitcase.

[0039] When it is necessary to move the housing 1, the operator can pull out the telescopic lever 64, tilt the housing 1, and move it flexibly using the universal casters 63. After reaching the working position, the lever 64 can be retracted, and the housing 1 can be placed stably, restoring its standard working posture.

[0040] like Figure 3 As shown, an open toolbox 65 is provided on the inside of the box 1.

[0041] An open toolbox 65 is installed on the inner wall of the housing 1. The toolbox 65 is designed to store various tools and spare parts commonly used in the maintenance of precision instruments. Its open structure ensures that the operator can intuitively, quickly and unobstructedly access the required items while wearing rubber gloves 12, thereby ensuring the continuity and efficiency of the maintenance process.

[0042] like Figure 4 As shown, the top of the toolbox 65 is hinged to the inner wall of the box body 1 so that the toolbox 65 can be flipped upwards.

[0043] The top of the open toolbox 65 is connected to the inner wall of the box body 1 via a hinge, forming a structure that can be flipped upwards. This allows the toolbox 65 to be flush against the inner wall when not in use, saving operating space; while when tools need to be replenished or the interior needs to be cleaned, it can be easily flipped upwards, providing completely unobstructed access and maintenance.

[0044] like Figure 5 As shown, a folding arm 66 is provided inside the box 1. One end of the folding arm 66 is rotatably connected to the inner wall of the box 1, and a magnifying glass 67 is provided at the other end of the folding arm 66.

[0045] Inside the housing 1, there is also a folding arm 66 mechanism. One end of the folding arm 66 is connected to the inner wall of the housing 1 via a pivot, enabling flexible rotation at multiple angles; the other end is equipped with a high-precision magnifying glass 67. This configuration greatly facilitates the operator's observation of the instrument's microscopic details, allowing them to complete fine visual operations inside the housing without the need for auxiliary tools.

[0046] like Figure 4 As shown, a supplementary light 68 is installed on the top of the box 1.

[0047] When starting the maintenance kit's operating system, the supplementary lighting 68 on the top of the kit can be turned on simultaneously. The light shines evenly from top to bottom across the entire working area, effectively eliminating shadows cast by the operator's arms and tools, making even the finest internal structures and damages of the instrument readily visible, greatly facilitating delicate operations.

[0048] like Figure 8 As shown, the exhaust port 14 is located on the bottom side of the box body 1. A perforated partition 15 is provided at the bottom of the box body 1. Two downward inclined guide plates 16 are provided at the bottom of the perforated partition 15. A partition plate 17 is provided between the two guide plates 16 and the perforated partition 15. A collection chamber 18 communicating with the exhaust port 14 is formed between the guide plates 16 and the ground inside the box body 1.

[0049] When the clean airflow from top to bottom carries dust particles generated during maintenance into the bottom of the chamber 1, these particles first fall through the perforated baffle 15. The falling dust then lands on two inclined guide plates 16 and slides down the slope into the dust collection chambers on both sides. The continuously flowing exhaust airflow eventually discharges the collected dust out of the chamber through the pressure valve 5 at the exhaust port 14.

[0050] The perforated baffle 15 ensures efficient separation of dust from the work area; the combination of the inclined guide plate 16 and the baffle 17 utilizes gravity to automatically collect dust, effectively preventing secondary re-entrainment at the bottom and ensuring clean exhaust efficiency. This system, working in conjunction with the top air supply system, forms a complete, efficient, and stable unidirectional flow cleanroom environment, which is crucial for ensuring successful maintenance of precision instruments.

[0051] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
