Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of optical instruments, in particular to an adjustable workbench and a microscope. BACKGROUND

[0002] The microscope stage is also called a mirror table, which is generally located below the objective lens and used to place the specimen to be observed. The structure of the existing stage includes a seat body and a light-transmitting glass. The seat body is provided with a limiting groove, and the light-transmitting glass is clamped in the limiting groove. In use, the glass slide is placed on the light-transmitting glass, the sample is placed on the glass slide and fixed by the cover glass, and finally the glass slide is fixed on the light-transmitting glass by the pressing clamp installed on the seat body, and then the objective lens focal length can be adjusted to observe the sample.

[0003] When the existing microscope observes the sample, the observation range of the objective lens is limited. When other positions of the sample need to be observed, the horizontal position of the glass slide needs to be adjusted. When the position of the glass slide is adjusted, the focal length of the corresponding objective lens also needs to be adjusted, which makes the observation operation of the whole sample more time-consuming. In order to keep the position of the glass slide relative to the light-transmitting glass unchanged, the mechanical structure type stage is provided on the market, which realizes the overall horizontal displacement by adding a ball guide rail. However, this structure is relatively high in cost and complex in structure. CONTENT OF THE INVENTION

DETAILED DESCRIPTION

[0047] The application will be further described below in conjunction with the drawings.

[0048] It should be noted that when an element is referred to as being "on" another element, it can be directly on the other element or intervening elements can also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements can also be present. The terms "vertical", "horizontal", "left", "right" and similar expressions as used herein are for illustrative purposes only and are not intended to be limiting.

[0049] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items. Example One

[0050] Figure 1 With Figure 2 A structure of an adjustable workbench is shown, which is applied to a seat body 2 installed on an object carrying table. The workbench comprises a pedestal 1, a light transmission glass 3, a magnetic attraction sheet 4 and a plurality of magnetic members 5. The pedestal 1 is made of metal material, comprising an integral object carrying part 11 and an adjusting part 12 extending perpendicularly from an end surface of the object carrying part 11 outward, and the overall cross section presents a T shape. The object carrying part 11 is provided with a mounting groove 111 on the upper surface, the light transmission glass 3 is clamped in the mounting groove 111, and at least one fastening screw 8 is threadedly connected to the side wall of the mounting groove 111, the end of the fastening screw 8 abuts against the outer side wall of the light transmission glass 3 to limit and fix the light transmission glass 3 in the mounting groove 111.

[0051] The carrier part 11 is also provided with at least one side opening 112 communicating with the mounting slot 111. In the embodiment, two side openings 112 are provided and symmetrically distributed. The cross section of the carrier part 11 can be circular, square or other regular / irregular shape according to requirements. The shape of the transparent glass 3 is also adjusted accordingly. In the embodiment, the carrier part 11 is circular and the transparent glass 3 is also circular.

[0052] The adjusting part 12 extends into the limiting slot 21. The magnetic sheet 4 is made of metal and is clamped in the limiting slot 21 of the seat body 2. In order to improve the installation stability of the magnetic sheet 4, the bottom of the magnetic sheet 4 is provided with a double-sided adhesive tape 7 which is adhered to the bottom of the limiting slot 21. The seat 1 and the magnetic sheet 4 are both provided with a light transmission hole 13 at the middle position, so that the light can pass through and irradiate the transparent glass 3.

[0053] The adjusting part 12 is circumferentially provided with a plurality of sink grooves 121 at the bottom position, and the magnetic member 5 is clamped in the sink groove 121. Since the seat 1 and the magnetic sheet 4 are both made of metal, the magnetic member 5 can be adsorbed on the adjusting part 12 and the magnetic sheet 4. Due to the provision of the sink groove 121, the magnetic force of the magnetic member 5 on the adjusting part 12 is greater than the adsorption force between the magnetic member 5 and the magnetic sheet 4, so that the magnetic member 5 will not be adsorbed on the magnetic sheet 4 when the adjusting part 12 is separated from the magnetic sheet 4.

[0054] In combination Figure 3 In the embodiment, the magnetic member 5 is a cylindrical magnetic steel. The adjusting part 12 can slide on the magnetic sheet 4, thereby realizing the sliding relative to the seat body 2. At the same time, the outer side wall of the adjusting part 12 and the slot wall of the limiting slot 21 have a spacing to form an adjusting gap. A rubber buffer ring is also provided on the outer side wall of the adjusting part 12. When the adjusting part 12 slides relative to the magnetic sheet 4 and reaches the slot wall of the limiting slot 21, the rubber buffer ring can abut against the slot wall to protect the adjusting part 12. In the embodiment, the height of the adjusting part 12 is greater than the depth of the limiting slot 21, so that the entire carrier part 11 is in a suspended state relative to the seat body 2. When the seat 1 slides relative to the seat body 2, there is no relative friction between the carrier part 11 and the seat body 2, thereby improving the service life of the two. Embodiment two
