The present invention relates to the technical field of microscopes, in particular to an angle adjustable microscope holder.
Digital microscopes are part of optical, digital and video microscope industries, and are widely applied to aspects in production and living such as intelligent manufacturing, quality control, medical assistance, teaching research, archeological exploration, collection authentication and so on.
In a process of using the digital microscope, it is necessary to fix a conventional microscope by using an extra holder, so that it is convenient to observe objects at a fixed angle. For example, a document with an application number 202021183539.2 discloses a digital microscope rotating holder. Although it is longer in lifting stroke and wide in rotating range, the design on stability is not excellent enough, and meanwhile, fine design is not available on connection between rotating pieces, friction between the rotating pieces is much, and errors such as displacement are caused as the rotating pieces are worn after long-term use. It is found by the inventor in further use that as far as the lifting rod with a long stroke is concerned, as weights of components at two ends are distributed on a same side, if stability design is not available on the lifting rod, it is easy to cause swing in up-down adjustment, and when the lifting rod is rotated, a component for fixing the microscope will have a radial rotary displacement relative to the lifting rod, which affects the precision of the microscope. Meanwhile, interference and wear which may happen on the rotating rod and the lifting rod are not solved well. Therefore, on this basis, it is necessary to further solve the stability of the lifting rod and the wear problem of the rotating pieces.
In order to solve the problem of stability, rotary wear and placing stability of the lifting rod in the prior art when the holder is rotated at an existing angle.

As described in the background art, in a scheme in the prior art, although it is lifted by way of the lifting rod and is matched with the rotating pieces to connect to realize a function that the lifting rod can be connected along with the rotating pieces, it has two design flaws: first, the lifting rod is prone to radial slippage when it inclines or it is adjusted in height as the lifting rod is cylindrical and there are many regions of arc-shaped surfaces; and second, as the lifting rod and the rotating axis of the rotating piece are in a same vertical surface, when the lifting rod rotates, the ultimate inclination angle thereof will make the lifting rod contact with the base first to lead to damage, and meanwhile, whether the rotating pieces are locked or not cannot be distinguished by judging whether the rotating pieces swing or not, so that there are still many aspects to be improved.
The present invention discloses an angle adjustable microscope holder. Referring to
In the embodiment, the moving piece 4 includes a movable support 42, one end of the movable support 42 being provided with the fixing ring 41 and the other end thereof being provided with a special-shaped hole 421 connected with the lifting rod in a sleeving manner, and the special-shaped hole 421 fitting a surface of the lifting rod in shape, wherein the angle adjustable microscope holder is further provided with an adjusting rod 43 penetrating through the movable support, the adjusting rod 43 being provided with a coaxial gear 431 in a sleeved manner, the coaxial gear 431 being partially exposed in the special-shaped hole and the coaxial gear being meshed with the spur rack. The adjusting rod can rotate when being impacted by an external force, and in the rotating process, its drives the coaxial gear to be meshed with the spur rack, so that it moves up and down along the spur rack. Furthermore, there is only the meshed portion of the coaxial gear exposed in the special-shaped hole, so that the assembling airtightness of the whole structure can be improved and it is guaranteed that displacement will not happen in repeated use.
In the embodiment, the moving piece 4 includes a rotary handle 44 and a nut bearing 45, the rotary handle 44 being fixedly connected with two ends of the adjusting rod, the adjusting rod 43 penetrating through the nut bearing 45 and the nut bearing 45 being fixedly connected with the movable support to form a limiting structure. The nut bearing can prevent the adjusting rod from being taken off in a twisting process, and meanwhile, the stability of the whole structure is improved.
In the embodiment, the movable support 42 is further provided with a fixing bolt 422, the fixing bolt 422 penetrates through the special-shaped hole, the fixing bolt is in threaded connection with the movable support, and the fixing bolt abuts against the lifting rod. By designing the special-shaped cross section, it is also necessary to fit the cross section in shape by using the fixing bolt, so that the abutting stability thereof can be improved.
