Description

Technical Field

[0001] This invention relates to a movable magnifying glass. Background Technology

[0002] A magnifying glass is a simple visual optical device used to observe minute details of objects. It is a converging lens with a focal length much smaller than the eye's visual distance. It typically consists of a convex lens, a frame, and a handle. When in use, the object is placed close behind the lens (within the focal length), and an upright, magnified virtual image can be seen, which helps to distinguish details. It is often used to view specimens, drawings, negatives, photographs, movie copies, etc.

[0003] In normal use, the observer needs to hold the magnifying glass or the object and then adjust the position of the magnifying glass or the object being observed in order to obtain better observation results.

[0004] Utility model application No. 201120434810.X discloses a universal rotating mechanism for a cold light magnifying lens lamp head, comprising a first swing joint head, a second swing joint head, and a third swing joint head, and a swing joint fixing seat connected sequentially. The first swing joint head can rotate relative to the second swing joint head around a first axis, the second swing joint head can rotate relative to the third swing joint head around a second axis, and the third swing joint head can rotate relative to the swing joint fixing seat around a third axis. The magnifying lens in this utility model has a small movement space. Summary of the Invention

[0005] Purpose of the invention:

[0006] A multi-directional adjustable magnifying glass for manual chip inspection is provided, which reduces manual operation and allows for arbitrary adjustment of spatial position.

[0007] Technical solution:

[0008] The present invention provides a multi-directional adjustable magnifying glass for manual chip inspection, comprising a base (which can be screwed onto a workbench), a human-shaped frame (with two supports forming a certain angle), a parallelogram truss (with two parallel support beams and two short rods movably connected to the support beams, which can form a parallelogram with variable angles), and a magnifying glass, connected in sequence.

[0009] The lower ends of the two supports of the human-shaped frame are movably connected to the base via rotatable joints, and one of the rotatable joints A is equipped with a locking knob A; the upper ends of the two supports of the human-shaped frame are movably connected together.

[0010] Both supports of the human-shaped frame can rotate around the lower joint at a certain angle. Locking knob A can temporarily fix the rotation angle between the lower end of the support and the base.

[0011] A short member of the truss is movably connected to the upper end of the humanoid frame via a rotating joint B. The joint may be equipped with a locking knob B, which can temporarily fix the rotation angle between the truss and the humanoid frame.

[0012] Another short rod is movably connected to the magnifying glass holder via a rotating joint C, which is equipped with a locking knob C, which can temporarily fix the rotation angle between the magnifying glass and the truss.

[0013] Joint C allows the free end of the magnifying glass, which is fixed by the clamp, to swing at a large angle around the end where the rotating joint C is located.

[0014] The rotating joint C and the clamping frame have a rotating component that can rotate relative to each other in the vertical plane, so that the magnifying glass fixed by the clamping frame can rotate as a whole at a large angle in the vertical plane.

[0015] One or two springs A are connected between the lower end of one support and the middle position of another support of the human-shaped frame. The change in the angle between the two supports, combined with the change in elastic force caused by the extension and contraction of the springs, gives the human-shaped frame a certain degree of elasticity and stability during rotation, and the human-shaped frame is not easy to cross or deform.

[0016] One or two springs B connect the beginning of one support beam of the truss to the middle position of another support beam. The relative misalignment between the two support beams, combined with the elastic force changes caused by the expansion and contraction of the springs, gives the truss movement and the misalignment between the two support beams a certain degree of elasticity and stability, making the truss less prone to parallel misalignment and deformation.

[0017] By moving the interconnected components, the magnifying glass can be moved over a wide area. By locking the knob, the position of the magnifying glass in space can be temporarily fixed.

[0018] Therefore, a magnifying glass can be moved in three-dimensional space and its viewing angle can be changed.

[0019] Beneficial effects:

[0020] The magnifying glass has a large displacement space, making it easy to observe objects of various sizes and positions; it is flexible in movement, allowing it to move in a large three-dimensional space and swing and rotate at different angles, offering a wide range of variations; once the locking knob is tightened, the entire structure is relatively stable, and the spring provides tension between the support or beam, making the displacement relatively flexible. Moreover, the combination of the spring and the locking knob makes it less prone to shifting due to gravity. Attached Figure Description

Detailed Implementation

[0026] like Figure 1 , 2 The multi-directional adjustable magnifying glass for manual chip inspection shown has a base 4, a human-shaped frame 3, a parallelogram truss 2, and a magnifying glass 1 connected together in sequence; the human-shaped frame 3 has two supports forming an angle of 10-45°; the parallelogram truss 2 has two parallel support beams and two short rods 10 that are movably connected to the support beams.

[0027] The lower ends of the two supports of the humanoid frame 3 are movably connected to the base 4 via rotatable joints; the upper ends of the two supports of the humanoid frame 3 are movably connected together. One of the supports has a locking knob A on its rotatable joint A14. Two springs 13 are connected between the lower end of one support and the middle position of the other support of the humanoid frame 3.

[0028] A short rod 10 of truss 2 is movably connected to the upper end of humanoid frame 3 via a rotating joint B9, which may be equipped with a locking knob B.

[0029] Another short rod 5 is movably connected to the holder 15 of the magnifying glass 1 via a rotating joint C6, which may be equipped with a locking knob C.

[0030] Rotating joint C6 allows the free end of the magnifying glass 1, which is fixed by the clamp 15, to swing 0-60° around the end where rotating joint C6 is located. Example

One of the supports has a locking knob A on its rotatable joint A14. Two springs 13 are connected between the lower end of one support and the middle position between the other support of the humanoid frame 3.
