Description

Technical Field

[0001] The utility model relates to the technical field of microscope accessories, in particular to a sample clamping adapter for a microscope stage. Background Art

[0002] A microscope is an optical instrument composed of a lens or a combination of several lenses. It is mainly used to magnify tiny objects to the extent that the human eye can see. It has become an indispensable and important tool in modern science and technology. Optical fluorescence microscopes are usually equipped with a stage that can translate samples. As an important component of the microscope system, it is used to support and position samples or objects for observation and analysis under the microscope. A sample adapter is required on the stage to fix the sample (such as a slide, a culture dish, a multi-well plate, etc.). At present, most common sample adapters are single fixed slots that can only hold a single standard slide or culture dish. There are also adapters that use the left and right claws to clamp the sample by squeezing from both ends to the middle. This type of adapter can achieve multi-type sample clamping, but when the pressure is too large, the sample will be lifted up and is not stable. In addition, the claws are connected to the bottom plate of the adapter through elastic components (such as spring sheets, compression springs, etc.), and they will swing left and right when moving and the movement is not smooth. Therefore, an adapter with high adaptability, convenient sample movement and reliable fixation is needed to solve this problem. Utility Model Content

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0024] The utility model aims to solve the problem that the existing adapter cannot meet the needs of diversified sample clamping and the sample movement is inconvenient. Figure 1-5 As shown, the following technical solution is provided: a sample clamping adapter for a microscope stage, comprising a base plate 1, the middle part of the base plate 1 is hollowed out; a pair of sliders 2, the sliders 2 are relatively slidably arranged in the middle part of the base plate 1, both ends of the sliders 2 are provided with guide components connected to the base plate 1, the middle part of the slider 2 is a clamping part 11, the lower side of the clamping part 11 is provided with a support plate 3, a sample clamping space is formed between the clamping part 11 and the support plate 3, different samples can be adapted by the movement of the slider 2, and the position adjustment of the sample on the adapter is also convenient, the clamping part 11 and the support plate 3 can clamp the two sides of the sample without affecting the movement of the sample, and the sample cannot move during the clamping process.

[0025] Specifically, the outer shape of the bottom plate 1 is adapted to the reserved adapter mounting hole of the stage, and can be stably placed at the corresponding position of the stage. The hollowing out of the middle of the bottom plate 1 will not affect the use of the microscope, and the hollowing out area can occupy most of the area of ​​the bottom plate 1. Only a position for setting up the slider 2 and the guide assembly is required on the bottom plate 1. The slider 2 can be set to be a long strip, and the clamping part 11 is located in the middle of the slider 2. The clamping part 11 is connected to the support plate 3 by a plurality of adjusting clamping screws 9, and the clamping screws 9 can be adjusted to adapt to the clamping of samples of different thicknesses.

[0026] When using, Figure 4 As shown, first adjust the distance between the two sliders 2 according to the length of the slide, place the two ends of the slide on the supporting plates 3 at both ends, and then move the sliders 2 relatively to clamp the two ends of the slide. If the position of the slide on the base plate 1 needs to be adjusted, just slide the two sliders 2 together.

[0027] Similarly, if you want to clamp the culture dish, such as Figure 5 As shown, the method of use is consistent with that of clamping a glass slide. Of course, the process of clamping a multi-well plate is also the same, so the adaptability range of the clamping adapter in this embodiment is relatively large.

[0028] As an implementation of the guide component, Figure 1-2 As shown, the guide assembly is a guide shaft 4 that passes through the end of the slider 2 horizontally. The guide shaft 4 can reliably guide the movement of the slider 2 without getting stuck. The guide shaft 4 can be an optical axis with high precision and good sliding guide effect. In order to improve the guiding effect and prevent the occurrence of jamming, the end of the slider 2 is provided with a linear bearing 5 sleeved on the guide shaft 4. The linear bearing 5 can reduce the friction between the slider 2 and the guide shaft 4. At the same time, in order to facilitate the installation of the linear bearing 5, the end of the slider 2 is provided with a clamping space with an opening on one side. The linear bearing 5 is arranged in the clamping space. At least one clamping screw 7 is arranged at one side of the opening of the clamping space. By turning the clamping screw 7, the clamping space can be tightened to clamp the linear bearing 5. After the linear bearing 5 is damaged, it is convenient to install and replace the linear bearing 5.

[0029] In this embodiment, if Figure 1 As shown, as an installation structure of the guide shaft 4, the two end portions of the guide shaft 4 are provided with clamping screws 6 connected to the base plate 1 in side by side, and the end portions of the guide shaft 4 are clamped between the two side-by-side clamping screws 6. The guide shaft 4 can be quickly installed and disassembled by the clamping screws 6. This installation method makes the processing of the base plate 1 very convenient. It is only necessary to open an installation groove at a position corresponding to the end portion of the guide shaft 4 on the base plate 1, and the clamping screws 6 are installed side by side in the installation groove to clamp the guide shaft 4 to a limit position.

[0030] In order to limit the sliding of the slider 2, as shown in FIG. Figure 1 As shown, a damping screw 8 is vertically penetrated at a position on the slider 2 corresponding to the base plate 1, and the lower end of the damping screw 8 is in contact with the base plate 1. The sliding resistance of the slider 2 can be adjusted by adjusting the friction between the damping screw 8 and the base plate 1, so that the slider 2 will not slide by itself. When the slider 2 does not need to slide, the damping screw 8 only needs to be rotated to lock the slider 2.

[0031] In order to limit the installation of the base plate 1, as Figure 3 As shown, a circle of sinking limiting parts 13 are provided at the edge of the bottom plate 1, and the entire bottom plate 1 can be limited in the corresponding mounting holes on the microscope stage through the sinking limiting parts 13.

[0032] like Figure 1-2 As shown, a sample contact protrusion 14 symmetrically distributed in a stepped shape is provided on the opposite side of the clamping portion 11, and a side wall of the sample contact protrusion 14 is an inclined surface 12 with a lower end indented inward. Different samples can be clamped by multiple sample contact protrusions 14, and the inclined surface 12 can apply downward pressure to the sample to prevent the sample from moving or being pushed upward due to force when clamping the sample.

[0033] In this embodiment, if Figure 1-2 As shown, a plurality of leveling screws 10 are vertically penetrated at the edge of the bottom plate 1. By adjusting the leveling screws 10, the deviation caused by the misalignment between the bottom surface of the sample and the microscope observation plane due to factors such as processing and assembly errors can be adjusted.

[0034] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0035] In addition, in the present invention, the descriptions of "primary", "secondary", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "primary" or "secondary" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0036] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.
