TECHNICAL FIELD

[0001] The utility model relates to microscope technical field especially relates to a stereomicroscope lifting fixture. BACKGROUND

[0002] The conventional stereomicroscope needs to manually fix the sample and manually adjust the sample position to facilitate accurate observation of the sample when in use, but manual operation can not avoid random error, so that the sample is not in the required state for detection on the object table, for example, the observation point is separated from the observation area due to the movement of the sample position, which affects accurate analysis and judgment of the details and structure of the sample, thereby bringing inconvenience to research, teaching and industrial detection and many other application scenarios. Therefore, a limiting fixture is needed to ensure observation accuracy, and the existing microscope test fixture is usually fixed on the object table, which hinders the movement of the sample when observing a large sample, and is not convenient for moving observation of large-size samples, greatly affecting the operation flexibility of the operator, thereby prolonging the observation time of a single sample and seriously reducing the observation efficiency. SUMMARY

[0005] The base acts as an object table and can be installed on the lens holder of the stereomicroscope for placing the sample, the fixed fixture can limit the movement of the sample, the position of the sample is fixed on the preset position, and the observation point of the stereomicroscope is located on the observation area of the sample. One end of the clamping seat is connected with the fixed fixture, and the remaining part is placed in the slide groove, the slide groove is located on the side surface of the base, the sliding clamping seat is convenient for the lifting of the fixed fixture. The embedding groove is consistent with the size of the fixed fixture and can completely accommodate the fixed fixture, so that the surface of the base is smooth and the movement of the sample is prevented.

[0006] In the preferred technical scheme of the utility model, the clamping seat is provided with a slide rail, and the fixed fixture is fixed with a sliding block in sliding connection with the slide rail.

[0007] The slide rail is arranged along the length direction of the clamping seat, the fixed fixture can be further adjusted in lifting by sliding the sliding block on the slide rail.

[0008] The utility model discloses a card seat is provided with the lever on the card seat, and the lever is used for lifting and moving and fixing the card seat.

[0009] The lever is arranged on the opposite side of the base, and the lever is used for conveniently operating the card seat by the operator, thereby improving the convenience.

[0010] In the preferred technical scheme of the utility model, the lever is threadedly connected with the card seat, and at least one screw hole is arranged on the groove wall of the sliding groove, and one end of the lever is inserted into the screw hole.

[0011] The screw hole is used for threadedly connecting with one end of the lever, so as to fix the height position of the lever, and then the lever is connected with the card seat to achieve the effect of fixing the height of the card seat. When the card seat needs to be moved, the lever is loosened, and the connection between the screw hole and the lever is released. If a plurality of screw holes are arranged, the fixing effect of different heights can be achieved by cooperation with different screw holes. Moreover, after the card seat is fixed, the height of the fixing clamp can still be accurately adjusted by the sliding block, so that the observation operation is relatively flexible.

[0012] In the preferred technical scheme of the utility model, an adjusting piece is arranged on the card seat, and the card seat is fixedly connected with the fixing clamp through the adjusting piece.

[0013] The adjusting piece is connected to the top end of the card seat, and the fixing clamp is fixed on the card seat. In this way, the adjusting piece can be used to change the limiting range by rotating the fixing clamp according to the sample observation area, so as to form different sample placement areas, so that the observation area matches the observation point.

[0014] In the preferred technical scheme of the utility model, the fixing clamp has a reference section and a reference section, and the reference section and the reference section are fixed perpendicular to each other.

[0015] The reference section is used for providing a reference edge against which the sample is placed, and the reference section is used for providing a reference edge. After the sample is placed against the reference edge, the position can be adjusted by referring to the gap between the sample and the reference edge. The right angle formed by the reference section and the reference section can also be directly used for fixing the sample, thereby achieving the effect of stable fixing.

[0016] In the preferred technical scheme of the utility model, the reference section and the reference section are hinged through a bolt.

[0017] The bolt hinge allows the reference section and the reference section to be adjusted at will, and the angle can be fixed by locking the bolt. It can be used for stably fixing smaller samples.

This solves the problem that when moving large-sized samples, the fixing fixture needs to be embedded into the base, and it is difficult to ensure the accuracy of observation by manually moving and fixing the sample.

[0020] In a preferred embodiment of this utility model, the moving mechanism includes a fixed platform and multiple support rods. The top surface of the fixed platform and the bottom surface of the base are provided with multiple corresponding spherical holes. The two ends of the support rods are spherical and are respectively installed in the spherical holes on the fixed platform and the base.

[0021] The fixed stage is mounted on the base of the stereomicroscope. Four support rods support the four corners of the base from the bottom surface. The two ends of the support rods are installed in spherical holes, which can rotate in all directions. Therefore, the base can be moved by rotating the support rods, thereby moving the sample and realizing mobile observation.

[0022] In a preferred embodiment of this invention, the bottom surface of the fixed platform is provided with adjustable feet.

[0023] Adjustable feet can compensate for the insufficient height drop when the base moves. By raising the adjustable feet, the base can be kept on the same horizontal plane, avoiding the need for the stereo microscope to refocus, thus affecting the observation efficiency.

[0024] The specific implementation process is as follows: Install the base onto the stereomicroscope mount and align the objective lens with the top surface of the base. Before observing the sample, use the lever to raise the mounting bracket, disengaging the fixing clamp from the insertion slot. Then, connect the lever to the screw hole to secure the mounting bracket. Further fine adjustment of the fixing clamp's height can be achieved by sliding the slider on the slide rail. During observation, place one side of the sample close to the reference section, and adjust the distance between the other side and the reference section as needed, or change the angle between the reference and reference sections to directly clamp and fix the sample until the observation point falls within the observation area. Observation can then begin. After observing one area, move the base and adjust the adjustable feet to move the remaining observation areas under the eyepiece, thus aligning the observation areas with the observation points for convenient mobile observation.

[0025] The beneficial effects of this utility model include at least the following:

[0026] This utility model provides a stereo microscope lifting fixture, which includes a base and a fixing clamp. The base is used to place the sample, and the fixing clamp is used to limit the edge of the sample, fixing the sample and standardizing its placement, ensuring consistent observation points. Through the sliding engagement of the clamp and the groove, the fixing clamp can be adjusted in height on the base. When observing smaller samples, it can be raised to a limit position. Simultaneously, the shape of the fixing clamp matches the embedding groove. When observing larger samples, the fixing clamp can be lowered to fully embed the sample into the base, avoiding obstruction of sample movement, increasing the operator's operational flexibility, shortening observation time, and thus improving detection efficiency.

[0041] Example 1

[0042] See Figure 1 , Figure 2 As shown, this application provides a stereomicroscope lifting fixture, including a base 1 and a fixing clamp 2. A vertical sliding groove 11 is provided on the side of the base 1, and a clamp 3 is movably disposed in the sliding groove 11. The clamp 3 is connected to the fixing clamp 2. An embedding groove 12 that cooperates with the fixing clamp 2 is also provided on the base 1.

[0043] Specifically, the base 1 is a square base that can be used as a stage. It is installed on the stereomicroscope mount to place the sample. The fixing clamp 2 can be a metal right-angle caliper with precise graduations to restrict sample movement and fix the sample in a preset position, so that the stereomicroscope observation point is located on the area of ​​the sample to be observed. The clamp 3 is a strip-shaped rigid clamp 3, which can be made of stainless steel. One end of it is fixed to the fixing clamp 2 with screws, and the rest is engaged in a straight concave groove 11. The groove 11 is located on the side of the base 1, which facilitates the sliding of the clamp 3 to raise and lower the fixing clamp 2. The embedding groove 12 is the same size as the fixing clamp 2 and can completely accommodate the fixing clamp 2, making the surface of the base 1 flat and preventing obstruction of sample movement.

[0044] See Figure 2 As shown, the card holder 3 is equipped with a lever 4, which is used to move the card holder 3 up and down and to fix it in place.

[0045] Specifically, the lever 4 and the card holder 3 are integrally formed and protrude on the opposite side of the base 1. It is cylindrical in shape to facilitate the operator's operation of the card holder 3 and improve convenience.

[0046] See Figure 2 As shown, the lever 4 is threadedly connected to the card holder 3, and the groove wall of the slide groove 11 is provided with at least one screw hole 5, and one end of the lever 4 is inserted into the screw hole 5.

[0047] Specifically, the outer wall of the extended section of the lever 4 is provided with external threads, and three screw holes 5 are provided along the length direction in the slide groove 11 for threaded connection with one end of the lever 4. A through hole is opened on the retainer 3 and tapped to achieve threaded connection with the lever 4. After the extended section of the lever 4 passes through the through hole, it is screwed into the screw hole 5, thereby fixing the height position of the lever 4 and thus fixing the height of the retainer 3. When it is necessary to move the retainer 3, the lever 4 is loosened, and the connection between the screw hole 5 and the lever 4 is released. Thus, different height fixing effects can be achieved by cooperating with different screw holes 5.

[0048] See Figure 1 As shown, the card holder 3 is provided with an adjusting member 6, and the card holder 3 and the fixed card 2 are fixedly connected by the adjusting member 6.

[0049] Specifically, the adjusting component 6 is a screw, and the top of the card holder 3 and the fixing clamp 2 are tapped with holes. The adjusting component 6 is connected to the top of the card holder 3 and fixes the fixing clamp 2 on the card holder 3. The limiting range can be changed by adjusting the tightness of the screw to rotate the fixing clamp 2 according to the area to be observed of the sample, thereby forming different sample placement areas so that the area to be observed matches the observation point.

[0050] Example 2

[0051] See Figure 3 , Figure 3 As shown, this embodiment provides a stereomicroscope lifting fixture, including a base 1 and a fixing clamp 2. A vertical sliding groove 11 is provided on the side of the base 1, and a clamping seat 3 is movably disposed in the sliding groove 11. The clamping seat 3 is connected to the fixing clamp 2. An embedding groove 12 that cooperates with the fixing clamp 2 is also provided on the base 1.

[0052] Specifically, the base 1 is a square base that can be used as a stage. It is installed on the stereomicroscope mount to place the sample. The fixing clamp 2 can be a metal right-angle caliper with precise graduations to restrict sample movement and fix the sample in a preset position, so that the stereomicroscope observation point is located on the area of ​​the sample to be observed. The clamp 3 is a strip-shaped rigid clamp 3, which can be made of stainless steel. One end of it is fixed to the fixing clamp 2 with screws, and the rest is engaged in a straight concave groove 11. The groove 11 is located on the side of the base 1, which facilitates the sliding of the clamp 3 to raise and lower the fixing clamp 2. The embedding groove 12 is the same size as the fixing clamp 2 and can completely accommodate the fixing clamp 2, making the surface of the base 1 flat and preventing obstruction of sample movement.

[0053] See Figure 3 As shown, a slide rail 31 is provided on the card holder 3, and a slider 21 that is slidably connected to the slide rail 31 is fixed on the fixing fixture 2.

[0054] Specifically, the linear slide rail 31 is arranged along the length of the card holder 3, the metal slider 21 is welded to the bend of the fixing fixture 2 and a silicone pad is provided in the slider 21. By manually controlling the slider 21 to slide on the slide rail 31, the fixing fixture 2 can be further adjusted in height. The slider 21 uses the silicone pad to clamp the two sides of the slide rail 31, which can achieve different heights of the card holder 3, eliminating the need for manual support of the fixing fixture 2.

[0055] See Figure 3 As shown, the fixing fixture 2 has a reference segment 22 and a reference segment 23, which are fixed perpendicularly to each other.

[0056] Specifically, the reference segment 22 is used to provide a reference edge that the sample can lean against when it is placed, and the reference segment 23 is used to provide a reference edge. After the sample leans against the reference edge, it can adjust its position by referring to the gap between itself and the reference edge. The reference precision scale can accurately adjust the distance. The right angle formed by the reference segment 22 and the reference segment 23 can also be used to fix the sample, which plays a role in stabilizing and fixing it.

[0057] See Figure 4 As shown, reference segment 22 and reference segment 23 are hinged together by bolts.

[0058] Specifically, the slider 21 is welded to one side of the reference section 22, and the bolt hinge allows the angle between the reference section 22 and the reference section 23 to be adjusted at will. The angle can be fixed by tightening the bolt, which can be used to securely fix smaller samples.

[0059] Example 3

[0060] See Figure 4 As shown, this embodiment provides a stereomicroscope lifting fixture, which also includes a moving mechanism 7, and a base 1 is movably mounted on the moving mechanism 7.

[0061] Specifically, the moving mechanism 7 allows the base 1 and the fixing clamp 2 to move as a whole while maintaining the fixation effect on the sample. This solves the problem that when moving large-sized samples, the fixing clamp 2 needs to be embedded into the base 1, and it is difficult to ensure the accuracy of observation by relying on manual movement and fixation of the sample.

[0062] See Figure 5 As shown, the moving mechanism 7 includes a fixed platform 71 and four support rods 72. Spherical holes are provided at the four corners of the top surface of the fixed platform 71 and the bottom surface of the base 1. The two ends of the support rods 72 are spherical and are respectively installed in the spherical holes on the fixed platform 71 and the base 1.

[0063] Specifically, the fixed stage 71 is installed on the base of the stereomicroscope, and four support rods 72 support the four corners of the base 1 from the bottom surface of the base 1 respectively. The two ends of the support rods 72 are installed in the spherical holes, which can all rotate in all directions. Therefore, the base 1 can be moved by means of the rotation of the support rods 72, thereby moving the sample and realizing mobile observation.

[0064] Furthermore, the bottom surface of the fixed platform 71 is equipped with adjustable feet.

[0065] Specifically, the adjustable feet compensate for the insufficient height drop of the base 1 when it moves. By raising the adjustable feet, the base 1 is kept on the same horizontal plane, avoiding the need for the stereo microscope to be refocused, thus reducing the impact on observation efficiency. It is understood that in this embodiment, a single large-sized adjustable foot is set at the center of the bottom of the fixed stage 71 to maintain the levelness of the fixed stage 71, thereby ensuring the levelness of the base 1 and reducing the impact on observation accuracy.

[0066] Further, see ​ As shown, the moving mechanism 7 can also be configured as a fixed platform 71 with a movable arm 8 on the top surface, and the two ends of the movable arm 8 are respectively fixed on the fixed platform 71 and the base 1.

[0067] Specifically, the movable arm 8 is divided into two sections. The connection between the movable arm 8 in the middle and the connection between the movable arm 8 and the fixed platform 71 and the base 1 are all connected by a ball joint. The connection method with the two ends of the support rod 72 and the fixed platform 71 and the base 1 is the same, so that the movable arm 8 can be flexibly twisted. In this way, it can both support the base 1 and allow the base 1 to move horizontally.

[0068] Furthermore, the fixed platform 71 has a movable cavity with a moving opening at the top. The bottom of the movable arm 8 is disc-shaped and is snapped into the movable cavity. The top of the movable arm 8 passes through the moving opening and is fixedly connected to the base 1.

[0069] Specifically, the movable cavity is disc-shaped and much larger than the bottom of the movable arm 8, allowing the movable arm 8 to move within the entire range of the movable opening. The operator can move the movable arm 8 by gripping it, and combined with the torsion of the movable arm 8 itself, the translation range of the base 1 is increased.

[0070] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
