Description

Technical Field

[0001] This utility model relates to the field of product inspection technology, and in particular to a portable visual inspection device with a shake-proof and stabilizing structure. Background Technology

[0002] In the field of product inspection technology, especially when conducting detailed inspections of industrial products, traditional visual inspection methods face many challenges. For example, when inspecting industrial pipelines, due to the dense network of pipelines, workers cannot clearly observe the inside of the pipelines, making it impossible to ensure the integrity of the pipeline interior.

[0003] Currently, many inspection tasks rely on manual handheld inspection tools. Due to the unavoidable shaking of the hands, the field of view during inspection is unstable. Taking the inspection of areas in industrial products that are difficult to see with the naked eye as an example, even slight hand tremors can prevent the inspected area from being clearly imaged. Inspectors find it difficult to accurately identify minor flaws, cracks, dimensional deviations, and other defects on the product surface. This greatly affects the accuracy and quality of inspection, which may lead to defective products entering the market or qualified products being mistakenly judged as unqualified, resulting in waste of resources and economic losses. Therefore, a portable visual inspection device with a shake-stabilizing structure is needed. Utility Model Content

[0004] The main objective of this invention is to provide a portable visual inspection device with a shake-proof and stabilizing structure, which can effectively solve the problems mentioned above.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A portable visual inspection device with a shake-stabilizing structure includes a visual inspection chamber. A protective eye pad is fixedly connected to the rear end of the visual inspection chamber. A magnifying glass is fixedly connected to the front of the inner surface of the visual inspection chamber. A movable groove is opened on the middle side of the rear of the lower end of the visual inspection chamber. A hand-held mechanism is movably connected to the inner cavity of the movable groove. Shake-stabilizing counterweights are fixedly connected to the middle side of the rear of the left and right ends of the visual inspection chamber.

[0007] Preferably, the two anti-shake counterweight components are symmetrically distributed from left to right.

[0008] Preferably, the handheld mechanism includes a rotating ball, which is movably connected to the inner cavity of the movable groove. A connecting rod is fixedly connected to the lower part of the outer surface of the rotating ball, and a handle is fixedly connected to the lower end of the connecting rod.

[0009] Preferably, the anti-shake counterweight assembly includes a connecting module, which is fixedly connected to the right rear middle side of the visual inspection cabin. The connecting module is open, and a movable rod is rotatably connected to the inner cavity of the connecting module. A counterweight block is fixedly connected to the end of the movable rod away from the connecting module. A rotating ring is fixedly connected to the upper end of the movable rod and the rotating shaft of the connecting module. A fixing mechanism is fixedly connected to the middle left side of the upper end of the connecting module.

[0010] Preferably, the fixing mechanism includes a rectangular compartment, which is fixedly connected to the upper left part of the connecting module on the same side. A fixing rod is slidably connected to the inner cavity of the rectangular compartment. A rebound spring is fixedly connected to the end of the fixing rod away from the rotating ring and the wall of the rectangular compartment away from the rotating ring. A rectangular hole is opened at the upper right part of the rectangular compartment.

[0011] Preferably, a lever is slidably connected to a portion of the outer surface of the fixed rod away from the rotating ring, and a slot is provided on the middle side of a portion of the outer surface of the rotating ring near the rectangular compartment.

[0012] Preferably, the fixing rod located on one side is engaged with the inner cavity of the slot on the same side.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The anti-shake counterweight component of this device forms a three-point stability with the front of the visual inspection chamber. When inspecting industrial products through the visual inspection chamber and magnifying glass, the anti-shake counterweight component uses its own weight to generate a counterforce to balance hand shaking, keeping the visual inspection chamber relatively stable, providing the staff with a clear and stable field of view, and significantly improving the inspection quality.

[0015] 2. The anti-shake counterweight component in this device can be freely expanded and contracted, allowing the anti-shake counterweight component to be folded up when carrying the device, reducing the space occupied by the device and improving its portability.

[0016] 3. This device, with its magnifying glass, allows staff to directly observe the inside of the pipe, ensuring the integrity of the pipe's interior. Attached Figure Description

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Example 1, as Figure 1 , Figure 2 and Figure 3 As shown, a portable visual inspection device with a shake-stabilizing structure includes a visual inspection chamber 1, a protective eye pad 3 fixedly connected to the rear end of the visual inspection chamber 1, a magnifying glass 6 fixedly connected to the front of the inner surface of the visual inspection chamber 1, a movable groove 7 opened on the middle side of the rear of the lower end of the visual inspection chamber 1, a hand-held mechanism 5 movably connected to the inner cavity of the movable groove 7, and a shake-stabilizing counterweight component 2 fixedly connected to the middle side of the rear of the left and right ends of the visual inspection chamber 1.

[0026] Furthermore, the two anti-shake counterweight components 2 are symmetrically distributed from left to right.

[0027] This device is used to inspect the interior of industrial products or pipelines, checking areas inside the products and pipelines that are not visible to the naked eye.

[0028] Before implementing this device, firstly:

[0029] The device is carried to the designated location via handheld mechanism 5;

[0030] After the device is carried to the designated location, the staff will then manipulate the anti-shake counterweight component 2 to rotate it to... Figure 1 The state shown increases the weight of the two devices by adding the anti-shake counterweight component 2.

[0031] In the above process, the staff takes the industrial product into their hands, then picks up the device and places the protective pad 3 in front of their eyes. The staff then inspects the industrial product through the magnifying glass 6.

[0032] In the above, the combined weight of the anti-shake counterweights 2 at the left and right ends of the visual inspection chamber 1 is equal to the combined weight of the front of the visual inspection chamber 1 and the magnifying glass 6. This makes the visual inspection chamber 1 and the two anti-shake counterweights 2 form a three-point structure. By utilizing the principle of stability of a triangle, the anti-shake counterweights 2, when deployed, can make the device more stable. This prevents the visual inspection chamber 1 from shaking when the operator is inspecting industrial products because of an unstable grip on the handheld mechanism 5.

[0033] As described above, through the movable connection between the handheld mechanism 5 and the movable slot 7, when the operator holds the handheld mechanism 5, if there is any shaking, the handheld mechanism 5 will shake inside the movable slot 7. However, under the action of the anti-shake counterweight component 2, the visual inspection chamber 1 will maintain a horizontal and stable position. No matter how the handheld mechanism 5 shakes left and right, the visual inspection chamber 1 will remain still, thus providing an anti-shake effect for the operator when inspecting industrial products.

[0034] In the above-mentioned case, when the device needs to be carried, the staff first releases the self-locking of the anti-shake counterweight component 2, then rotates the anti-shake counterweight component 2 to the horizontal position to reduce the space occupied by the device, and then directly puts the device into the bag or carries it directly, thus improving the convenience of the device.

[0035] As mentioned above, the magnifying glass 6 uses high-quality optical glass or resin lenses, which have the characteristics of high definition and low chromatic aberration.

[0036] Furthermore, during the movement of the handheld mechanism 5 within the movable slot 7, refer to... Figure 4 The handheld mechanism 5 includes a rotating ball 51, which is movably connected to the inner cavity of the movable groove 7. A connecting rod 52 is fixedly connected to the lower part of the outer surface of the rotating ball 51, and a handle 53 is fixedly connected to the lower end of the connecting rod 52.

[0037] In the above-mentioned process, when inspecting industrial products, medical personnel hold handle 53 and then pick up the device.

[0038] In the above, when the operator's hand shakes, the handle 53 and the connecting rod 52 will tilt to one side. At this time, through the movable connection between the rotating ball 51 and the movable groove 7, the connecting rod 52 will drive the rotating ball 51 to rotate in the inner cavity of the movable groove 7. Under the action of the anti-shake counterweight component 2, the visual inspection chamber 1 will remain horizontal and still, thereby achieving the purpose of stabilizing the visual inspection chamber 1, so that the operator will not be affected by hand shaking when inspecting the work product.

[0039] Furthermore, in order to achieve the purpose of unfolding and retracting the anti-shake counterweight component 2, refer to... Figure 5 and Figure 6The anti-shake counterweight component 2 includes a connecting module 25, which is fixedly connected to the right rear middle side of the visual inspection chamber 1. The connecting module 25 is open, and a movable rod 23 is rotatably connected to the inner cavity of the connecting module 25. A counterweight block 24 is fixedly connected to the end of the movable rod 23 away from the connecting module 25. A rotating ring 22 is fixedly connected to the upper end of the rotating shaft of the movable rod 23 and the connecting module 25. A fixing mechanism 21 is fixedly connected to the middle left side of the upper end of the connecting module 25.

[0040] Furthermore, the fixing mechanism 21 includes a rectangular compartment 211, which is fixedly connected to the upper left part of the connecting module 25 on the same side. A fixing rod 214 is slidably connected to the inner cavity of the rectangular compartment 211. A spring 215 is fixedly connected to the end of the fixing rod 214 away from the rotating ring 22 and the wall of the rectangular compartment 211 away from the rotating ring 22. A rectangular hole 212 is opened on the upper right part of the rectangular compartment 211.

[0041] Furthermore, a lever plate 216 is slidably connected to a part of the outer surface of the fixed rod 214 away from the rotating ring 22, and a slot 213 is provided on the middle side of a part of the outer surface of the rotating ring 22 near the rectangular compartment 211.

[0042] Furthermore, the fixing rod 214 located on one side is engaged with the inner cavity of the slot 213 on the same side.

[0043] In the above-mentioned process, before implementing this device, the operator first manually moves the movable rod 23 to rotate it within the cavity of the connecting module 25, causing the counterweight 24 to rotate backward. When the movable rod 23 rotates, it also causes the rotating ring 22 to rotate. When the movable rod 23 rotates the rotating ring 22 to a certain angle, the slot 213 and the fixed rod 214 will be aligned. At this time, the return spring 215 will push the fixed rod 214 into the slot 213, fixing the rotating ring 22 in place. This, in turn, fixes the movable rod 23 and the counterweight 24 in place, preventing the counterweight 24 from moving. Then, the visual inspection chamber 1 is supported by a three-point support method consisting of the two counterweights 24 and the front of the visual inspection chamber 1, ensuring that the visual inspection chamber 1 will not shake when the magnifying glass 6 inspects industrial products, thus ensuring the stability of the visual inspection chamber 1.

[0044] In the above-mentioned case, when the device needs to be carried, first manually pull the lever 216 to move it closer to the visual inspection chamber 1, so that the lever 216 drives the fixed rod 214 to slide together in the inner cavity of the rectangular compartment 211, and pull the fixed rod 214 out of the slot 213. Then, the movable rod 23 can be turned to make the counterweight 24 rotate back to its original position, reducing the space occupied by the device and making the device easy to carry.

[0045] Example 2: This device can also be implemented in other ways:

[0046] The visual inspection chamber 1, goggle pad 3, and magnifying glass 6 in the device can be replaced with a camera. Its anti-shake counterweight 2 is used to balance the camera, so that when the operator holds the camera, the anti-shake counterweight 2 keeps the camera stable. The camera can use the existing technology model: C30N camera. When inspecting industrial products, it can also record, recording the defective industrial products in the camera, so that the operator can handle the defective industrial products in a unified manner based on the recorded information.
