Description

Technical Field

[0001] This utility model relates to the field of microscope bracket structures, and in particular to a sliding bracket for microscope assembly. Background Technology

[0002] In existing designs of microscope sliding supports, the assembly method typically involves installing individual ball bearings one by one into the slide groove. This traditional method has significant drawbacks: firstly, the ball bearings are prone to falling off or becoming misaligned during installation due to limited operating space or unstable clamping, resulting in low assembly efficiency and time-consuming repeated adjustments; secondly, the dispersed ball bearings may shift or fall off due to vibration or friction during long-term use, affecting the smoothness of the sliding support's movement and positioning accuracy. Furthermore, the manual, ball-by-ball installation method requires a high level of operator skill, further increasing production costs and maintenance difficulty. While there have been attempts to use cage structures in existing technologies, most solutions still cannot achieve rapid, integrated assembly and reliable fixation of the ball bearings, limiting their practical application effectiveness. Utility Model Content

[0003] To overcome the aforementioned deficiencies of the prior art, embodiments of this utility model provide a sliding bracket for microscope assembly. The technical problem to be solved by this utility model is: how to provide a ball bearing mounting structure for a microscope sliding bracket to overcome the defects of low ball bearing mounting efficiency, easy detachment, and insufficient assembly stability in the prior art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a sliding bracket for microscope assembly, comprising a bracket one; a bracket two, which can slide relative to the bracket one; a strip body located between the bracket one and the bracket two, including a limiting frame and ball bearings, the limiting frame and the bracket two being connected, a plurality of ball bearings being placed in the limiting frame in an embedded and rolling manner, the outermost edge of the ball bearings extending outside the limiting frame, the outer wall of the ball bearings being used to contact the side walls of the bracket one and the bracket two, the diameter of the ball bearings being larger than the opening diameter of the limiting frame, when the ball bearings enter the limiting frame, the upper part of the limiting frame can be deformed, and when the ball bearings leave the opening of the limiting frame, the opening shape of the limiting frame returns to its original shape; and a stop member used to limit the position of the bracket one and the bracket two.

[0005] In a preferred embodiment, the limiting frame includes four limiting rods, which are evenly distributed on the outside of the ball to limit the movement of the ball.

[0006] In a preferred embodiment, the strip body further includes a trumpet-shaped transition tube. The diameter of the end of the transition tube connected to the shaping ring is larger than that of the ball bearing, and the diameter of the end of the transition tube connected to the limiting frame is smaller than that of the ball bearing. The hardness of the shaping ring is greater than that of the transition tube. When the ball bearing enters the limiting frame, the transition tube can deform.

[0007] In a preferred embodiment, a limiting hole is provided inside the transition tube, which is used to engage with the edge of the embedding groove.

[0008] In a preferred embodiment, bracket one includes a support plate, a protruding ridge, and a contact wall. The support plate has a contact wall inside, and the support plate protrudes outward to form a protruding ridge. Bracket two includes a slide table, a slide groove, and an embedding groove. The slide table has a slide groove inside, and the protruding ridge and the slide groove are slidably connected. The outer wall of the ball is in contact with the embedding groove and the contact wall.

[0009] In a preferred embodiment, the groove width of the slide on the lower side of the slide is greater than the groove width of the slide on the upper side of the slide.

[0010] In a preferred embodiment, the top of the tray and the slide is detachably connected to a cover.

[0011] In a preferred embodiment, the stop includes a locking bolt and a soft pad. The threaded portion of the locking bolt extends through the support plate and into the slide, and the threaded portion is threadedly connected to the support plate. The soft pad is fixed to the side wall of the slide, and the end face of the threaded portion of the locking bolt can abut against the soft pad.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] This application significantly simplifies the ball bearing installation process by pre-pressing multiple balls into a limiting frame to form a ball bearing strip structure. This design enables rapid batch positioning and integral embedding of the balls into the sliding groove, preventing ball bearing scattering or misalignment during installation and greatly improving assembly efficiency and consistency. Simultaneously, the limiting frame's constraint on the balls effectively reduces the risk of ball bearing displacement or detachment during use, enhancing the smoothness of the sliding bracket's movement and long-term reliability. Furthermore, this structure eliminates the need for high-precision operation or complex tooling, reducing production costs and maintenance difficulty. It features strong compatibility and wide applicability, providing an innovative solution for the design of precision moving parts in microscopes. Attached Figure Description

[0023] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0024] Example

[0025] like Figures 1-6 It includes several main parts, such as bracket 10, bracket 20, strip body 30, stop 40, and lens barrel 50.

[0026] The bracket 10 includes a tray 11 and a cover 12. The cover 12 is used to cover the top of the tray 11 and is removable when in use. When not in use, it serves to prevent dust and improve aesthetics.

[0027] The bracket 20 includes a slide table 21 and a slide groove 22. The slide table 21 has slide grooves 22 on both sides to facilitate the sliding of the protrusion 13 on the support plate 11 and improve the stability of the sliding between the support plate 11 and the slide table 21.

[0028] Preferably, the lower groove diameter of the slide 22 is larger than the upper groove diameter, which makes it easier for the tray 11 to slide into the slide table 21 from below, thus improving the ease of installation of the tray 11 and the slide table 21.

[0029] After the tray 11 and the slide 21 are connected, a space is formed in the middle of the two for the strip body 30 to be placed. The tray 11 protrudes to form a contact wall 14, and the slide 21 is recessed to form an embedding groove 23. The strip body 30 is placed between the contact wall 14 and the embedding groove 23.

[0030] The strip body 30 includes a shaping ring 31, a limiting frame 33, and ball bearings 34. The shaping ring 31 is made of a non-deformable material, such as carbon steel. The lower part of the shaping ring 31 is connected to the limiting frame 33 through a transition tube 32. Several ball bearings 34 are inserted into the limiting frame 33 in an embedded manner, allowing them to roll within the limiting frame 33. By inserting the limiting frame 33 into the embedding groove 23 and ensuring that the spherical outer walls of the ball bearings 34 contact the contact wall 14 and the side wall of the embedding groove 23 respectively, the rolling of the ball bearings 34 ensures smoothness when the support plate 11 and the slide table 21 move relative to each other. Furthermore, all the ball bearings 34 are press-fitted into the limiting frame 33, making it convenient to pick up and remove them.

[0031] It should be noted that the outermost wall of the ball 34 is located outside the limit frame 33.

[0032] Preferably, the limiting frame 33 can be directly connected to the embedding groove 23 by adhesive.

[0033] Preferably, the limiting frame 33 is connected to the embedding groove 23 via the transition tube 32. The transition tube 32 has a flared structure. The diameter of the end connecting the transition tube 32 and the shaping ring 31 is larger than that of the ball 34, while the diameter connecting the transition tube 32 and the limiting frame 33 is smaller than that of the ball 34. During the process of the ball 34 being pressed from the shaping ring 31 into the transition tube 32 and the limiting frame 33, the transition tube 32 needs to be squeezed first to deform it, so that the ball 34 can be pressed into the limiting frame 33. After the ball 34 enters the limiting frame 33, the transition tube 32 resets, which serves to prevent the ball 34 from detaching from the limiting frame 33. The limiting frame 33 does not squeeze or interfere with the ball 34, but only limits the ball 34.

[0034] The deformation capability of the transition tube 32 is stronger than that of the stabilizing ring 31, so that the stabilizing ring 31 can play the role of stabilizing the structure of the transition tube 32.

[0035] Preferably, limiting holes 35 are provided on the four sides of the transition tube 32. The limiting holes 35 can be locked on the three sides of the embedding groove 23 to limit the entire strip body 30.

[0036] Furthermore, the lens tube 50 is fixed to the slide 21.

[0037] It should be noted that the movement of the tray 11 and the slide 21 is conventional, such as manually rotating the coarse / fine focus knob to directly drive the gear or screw mechanism, causing the slide 21 to slowly rise and fall. Since this product does not involve drive components, but focuses on the components that provide smooth sliding between the tray 11 and the slide 21, the drive method will not be described in detail. When the tray 11 and the slide 21 are moved relative to each other using existing technology, the slide 21 will drive the belt 30 to move.

[0038] Furthermore, the stop 40 limits the position of the support plate 11 and the slide table 21. The stop 40 includes a bolt 41 and a soft pad 42.

[0039] In this embodiment, the support plate 11 is set to surround the outside of the slide table 21 in a semi-enclosed structure. The bolt 41 and the support plate 11 are threaded together. As the bolt 41 is rotated, the end of the bolt 41 will press against the slide table 21, and the support plate 11 and the slide table 21 will be pressed and limited by pressure.

[0040] Preferably, a soft pad 42 is glued to the side wall of the slide table 21, so that the threaded end of the bolt 41 is directly pressed against the soft pad 42. Because the surface of the soft pad 42 is softer, the deformation is greater, and the contact area with the end of the bolt 41 is larger, so the limiting effect is more stable.

[0041] This embodiment significantly simplifies the installation process of the balls 34 by pre-pressing multiple balls 34 into the limiting frame 33 to form a ball strip structure. This design enables rapid batch positioning and overall embedding of the balls 34 into the sliding groove, avoiding the scattering or misalignment of the balls 34 during installation and greatly improving assembly efficiency and consistency. Simultaneously, the constraint effect of the limiting frame 33 on the balls 34 effectively reduces the risk of ball 34 shifting or falling off during use, enhancing the smoothness of the sliding bracket's movement and long-term reliability. Furthermore, this structure does not rely on high-precision operation or complex tooling, reducing production costs and maintenance difficulty. It features strong compatibility and wide applicability, providing an innovative solution for the design of precision moving parts in microscopes.

[0042] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
