Technical Field

[0001] This application relates to the field of magnifying glass technology, and in particular to a portable desktop magnifying glass. Background Technology

[0002] In the field of magnifying glass technology, with the continuous development of industrial production, the demand for product quality inspection is increasing. In industries such as plastics manufacturing, product quality inspection is particularly crucial, as it determines whether products meet relevant standards and satisfy market demands. Accurate quality inspection not only helps improve production efficiency and reduce defect rates but also enhances a company's market competitiveness and protects consumer rights. Meanwhile, magnifying glasses, as a commonly used inspection tool, play an important role in quality inspection processes across various industries, and their performance and convenience are receiving increasing attention.

[0003] Currently, in the production of plastic products, magnifying glasses are widely used in the industry to detect common quality defects such as foreign matter contamination. Existing magnifying glasses typically consist of a base and a magnifying glass mounted on the base, with an LED ring light strip coaxially aligned with the lens. This structure provides illumination during inspection, facilitating observation of product details by operators.

[0004] However, existing magnifying glasses have relatively simple structures and can only provide relatively fixed lighting methods and observation angles, which are difficult to meet the inspection needs in complex situations. For example, when the object being inspected has curved structures, concave parts, or special textures, blind spots are easily generated, leading to missed detection of foreign objects or defects, thus affecting the inspection quality, which needs to be improved.

[0025] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0026] Example 1: This application discloses a portable desktop magnifying glass.

[0027] Reference Figure 1 A portable desktop magnifying glass includes a base 1, a magnifying glass body 2, an auxiliary light 3, a lifting assembly 4, a main light, and a universal hose 5. The main light is located on the magnifying glass body. The lifting assembly 4 is used to install the magnifying glass body 2 on the base 1 and to vertically adjust the height of the magnifying glass body 2. The auxiliary light 3 is installed on the base 1 through the universal hose 5 and its position and angle can be adjusted at will.

[0028] Reference Figure 2 Specifically, the lifting assembly 4 includes a vertical rod 42 and an adjusting block 41. The vertical rod 42 is vertically installed on the base 1 and is generally made of metal, which has good strength and stability. Of course, high-strength plastic or other materials can also be used as substitutes. The magnifying glass body 2 is installed on the adjusting block 41. The adjusting block 41 has a first adjusting hole 43 in the middle. The size of the first adjusting hole 43 is just right to be inserted and matched with the vertical rod 42, so that the adjusting block 41 can slide up and down along the vertical rod 42.

[0029] The side wall of the adjusting block 41 is provided with a second threaded hole 44, and a first screw 45 is installed in the internal thread of the second threaded hole 44. One end of the first screw 45 is used to abut against the outer wall of the vertical rod 42. In order to enhance the friction between the first screw 45 and the vertical rod 42, a rubber pad 46 is provided at the end of the first screw 45. The rubber pad 46 is soft and has a large coefficient of friction, which can better fix the position of the adjusting block 41.

[0030] When it is necessary to adjust the height of the magnifying glass body 2, loosen the first screw 45, and the adjusting block 41 can slide freely on the vertical rod 42. After adjusting to the appropriate height, tighten the first screw 45 so that the rubber pad 46 presses tightly against the vertical rod 42, thereby fixing the position of the adjusting block 41 and thus realizing the height adjustment of the magnifying glass body 2.

[0031] In this embodiment, a crossbar 21 is provided on one side of the magnifying glass body 2. The adjusting block 41 has a second adjusting hole 23 for sliding the crossbar 21. The adjusting block 41 is provided with a second screw 22 for abutting against the outer wall of the crossbar 21. The connection method between the second screw 22 and the crossbar 21 is the same as the connection method between the first screw 45 and the vertical bar 42, which will not be shown or described here. The cooperation between the crossbar 21 and the second adjusting hole 23 can adjust the horizontal position of the magnifying glass body 2, which further facilitates the adjustment of the position of the magnifying glass body 2 according to the product structure.

[0032] In other embodiments, the lifting assembly 4 can be configured as two support rods, which are hinged together. The ends of the two support rods away from their hinge points are respectively rotatably connected to the magnifying glass body 2 and the base 1. A rubber layer is provided at the hinge points of the support rods, that is, the rubber layer is provided at the hinge points between the support rods and at the hinge points between the support rods and the magnifying glass body 2 / base 1. The rubber layer can increase the friction at the hinge points of the support rods and prevent the hinge points of the support rods from rotating freely. The height position of the magnifying glass body 2 can be adjusted by rotating the support rods.

[0033] The main light has multiple bulbs, all of which are mounted on the magnifying glass body 2 and spaced apart around the lens axis of the magnifying glass body 2. The bulbs can be adjusted to different colors of light, and the light intensity can also be adjusted according to actual needs, further improving the practicality of the magnifying glass.

[0034] Reference Figure 1 The universal flexible hose 5 is connected to the auxiliary light 3 at one end and to the base 1 at the other end. The universal flexible hose 5 consists of a metal spiral tube and an outer protective sleeve. The metal spiral tube gives it the ability to bend and shape freely, while the protective sleeve protects the internal structure and enhances its appearance. The protective sleeve can be made of rubber or plastic.

[0035] The auxiliary light 3 typically uses LED bulbs, which are characterized by low energy consumption and high brightness. Other types of energy-saving lamps can also be used. By bending the universal flexible hose 5, the auxiliary light 3 can be adjusted to any angle and position, providing multi-angle illumination for the inspected items.

[0036] The implementation principle of Embodiment 1 of this application is as follows: This portable desktop magnifying glass combines an adjustable lifting assembly 4 with a flexible universal tube 5 connecting to an auxiliary lamp 3. Compared to traditional magnifying glasses, it allows for flexible adjustment of the height of the magnifying glass body 2 and the illumination angle and position of the auxiliary lamp 3 according to actual inspection needs. This greatly improves the flexibility and accuracy of inspection, making it particularly suitable for detecting foreign objects in plastic products under complex conditions. It solves the problems of fixed illumination methods and observation angles in traditional magnifying glasses, providing a more practical tool for industrial product quality inspection and improving inspection efficiency and quality.

[0037] Example 2: This application discloses a portable desktop magnifying glass.

[0038] Reference Figure 3 and Figure 4 The difference between Embodiment 2 and Embodiment 1 is that: both sides of the base 1 are provided with sliding grooves 11, and one end of each sliding groove 11 is connected to the outside; one end of the universal hose 5 is provided with a slider 12, which is generally made of plastic or metal and its shape is adapted to the sliding groove 11 so that the slider 12 can slide smoothly in the sliding groove 11, and the slider 12 is fixed to the inner wall of the sliding groove 11 by the positioning component 6.

[0039] Reference Figure 4 and Figure 5 The positioning component 6 includes a fixing block 61, a spring 62, and an unlocking part 63. A movable groove 13 is formed on the outer wall of the slider 12, and the fixing block 61 is movably installed within the movable groove 13. The fixing block 61 is typically a metal block, square or round in shape. Multiple fixing grooves 14 are formed on the inner wall of the slide groove 11 for the fixing block 61 to insert into. These fixing grooves 14 are evenly distributed on the inner wall of the slide groove 11. The spring 62 is located within the movable groove 13, with one end connected to the bottom of the movable groove 13 and the other end connected to the fixing block 61. It is used to drive the fixing block 61 to be normally inserted into the fixing groove 14, thus fixing the universal hose 5 in a certain position.

[0040] The unlocking part 63 is rod-shaped and can be made of plastic or metal. The slider 12 has an unlocking groove 15 on the side away from the base 1, which communicates with the movable groove 13. The unlocking part 63 is slidably installed in the unlocking groove 15 and connected to the fixing block 61. When the position of the auxiliary light 3 needs to be adjusted, the unlocking part 63 is pressed to overcome the spring force of the spring 62, causing the fixing block 61 to exit from the fixing groove 14. At this time, the slider 12 can slide within the sliding groove 11. After adjusting to the appropriate position, the unlocking part 63 is released, and the spring 62 pushes the fixing block 61 into the corresponding fixing groove 14, thereby fixing the position of the universal hose 5.

[0041] In this embodiment, a pull plate 64 is provided at the end of the unlocking part 63 away from the fixing block 61. The pull plate 64 makes it easier for the staff to pull the unlocking part 63, thus improving convenience.

[0042] The implementation principle of Embodiment 2 of this application is as follows: With the positioning component 6, the position adjustment of the auxiliary lamp 3 is more precise and stable. Compared with the ordinary universal flexible hose 5 connection method, this structure with positioning function can firmly fix the auxiliary lamp 3 after it is adjusted to the appropriate position, and it will not be moved due to accidental touch. This further improves the stability and reliability of the auxiliary lamp 3 illumination and enhances the practicality of the portable desktop magnifying glass in actual testing.

[0043] This application discloses a portable desktop magnifying glass.

[0044] Reference Figure 6 The difference between Embodiment 3 and Embodiment 2 is that: the positioning component 6 includes a bolt 65 and a rubber strip 66, the extension direction of the mounting groove 17 is in the same direction as the extension direction of the slide groove 11; the inner wall of the slide groove 11 is provided with a mounting groove 17, and the rubber strip 66 is disposed in the mounting groove 17; the fixing block 61 is provided with a first threaded hole 16 on the side away from the base 1, and the bolt 65 is installed in the first threaded hole 16 to abut against the rubber strip 66.

[0045] The implementation principle of Embodiment 3 of this application is as follows: By tightening the bolt 65, the end of the bolt 65 abuts against the rubber strip 66, thereby increasing the friction of the slider 12 in the groove 11 and preventing the slider 12 from sliding freely in the groove 11, thus completing the fixation of the slider 12 in the groove 11; so that the position of the universal hose 5 can be adjusted according to the operator's operating habits.

[0046] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
