[0035] According to the following Figures 1 to 5 A driver 10 for a microscope 100 and a microscope 100 according to an embodiment of the present invention are described in detail.

[0036] like Figure 1 and Figure 2 As shown, the driver 10 for the microscope 100 according to the embodiment of the utility model comprises: a housing 11, the housing 11 is configured to be fixedly connected to a support 101 of the microscope 100; a sliding member 13, the sliding member 13 is slidably connected to the housing 11, and the sliding member 13 is configured to install an objective lens converter 103 of the microscope 100; an operating shaft 15, the operating shaft 15 is rotatably connected to the housing 11; and a transmission assembly 17, the transmission assembly 17 is drivably connected between the operating shaft 15 and the housing 11. The sliding member 13 is arranged such that when the operating shaft 15 rotates, the sliding member 13 is driven to slide relative to the housing 11 through the transmission assembly 17, wherein the operating shaft 15 passes through the housing 11, and the operating shaft 15 has a first end 151 and a second end 152 opposite to each other, the first end 151 of the operating shaft 15 extends out of the housing 11 and is rotatably connected to the housing 11, and the second end 152 of the operating shaft 15 extends out of the housing 11 and is configured to be rotatably connected to the bracket 101 of the microscope 100.

[0037] In the driver 10 for the microscope 100 according to the embodiment of the utility model, the first end 151 of the operating shaft 15 of the driver 10 extends out of the housing 11 and is rotatably connected to the housing 11, the second end 152 of the operating shaft 15 extends out of the housing 11 and is rotatably connected to the support 101 of the microscope 100, and the housing 11 of the driver 10 is connected to the support 101 of the microscope 100. That is, the first end 151 of the operating shaft 15 is supported to the support 101 of the microscope 100 through the housing 11, and the second end 152 is directly rotatably supported to the support 101 of the microscope 100. Thus, the operating shaft 15 is stably supported, and the bending generated on the operating shaft 15 when the operating shaft 15 is manipulated is reduced, thereby avoiding the displacement of the objective lens converter 103 caused thereby and significantly improving the drift of the image.

[0038] In some embodiments, Figure 1 As shown, the second end 152 of the operating shaft 15 is configured to be rotatably connected to the support 101 of the microscope 100 through a bearing 18. Thus, the second end 152 of the operating shaft 15 can be rotated relative to the support 101 of the microscope 100 while being stably supported on the support 101 of the microscope 100.

[0039] In some embodiments, Figure 4 As shown, the second end 152 of the operating shaft 15 is matched with the inner ring 181 of the bearing 18. It can be understood that the second end 152 of the operating shaft 15 and the inner ring 181 of the bearing 18 form an interference fit or a transition fit, so that the second end 152 of the operating shaft 15 is firmly matched in the bearing 18.

[0040] In some embodiments, Figure 4 As shown, the outer ring 182 of the bearing 18 is configured to be fixedly connected to the bracket 101 of the microscope 100. Thus, the inner ring 181 of the bearing 18 can rotate relative to the outer ring 182 of the bearing 18, so that the second end 152 of the operating shaft 15 can rotate relative to the outer ring 182 of the bearing 18.

[0041] In some embodiments, Figure 1 As shown, the bearing 18 is configured to be fixedly connected to the inner side of the bracket 101 of the microscope 100. Thus, the bearing 18 stably supports the operating shaft 15, and since the bearing 18 cannot be observed from the outside of the microscope 100, the appearance of the microscope 100 is neat and beautiful.

[0042] In some embodiments, Figure 4As shown, the bearing 18 is configured to be fixedly connected to the outside of the support 101 of the microscope 100. Thus, the bearing 18 is arranged closer to the second end 152 of the operating shaft 15, which is beneficial to further reduce the bending of the operating shaft 15 at the second end 152 when the operating shaft 15 is manipulated.

[0043] In some embodiments, Figure 4 As shown, the outer ring 182 of the bearing 18 is configured to fit in the opening of the bracket 101 of the microscope 100. Thus, the bending of the operating shaft 15 at the second end 152 when the operating shaft 15 is manipulated can be further reduced while keeping the appearance of the microscope 100 neat and beautiful.

[0044] In some embodiments, Figure 4 As shown, the driver 10 further includes a bearing seat 183, the bearing 18 is configured to be arranged between the bearing seat 183 and the support 101 of the microscope 100 along the axial direction of the operating shaft 15, and the bearing seat 183 is configured to be fixedly connected to the support 101 of the microscope 100 and press the outer ring 182 of the bearing 18 against the support 101 of the microscope 100. Therefore, the fixed connection between the outer ring 182 of the bearing 18 and the support 101 is simple and reliable through the bearing seat 183.

[0045] In some embodiments, Figure 4 As shown, the bearing seat 183 is configured to be fixedly connected to the bracket 101 of the microscope 100 by bolts. Thus, it is easy to realize the fixed connection between the bearing seat 183 and the bracket 101 by bolts.

[0046] In some embodiments, Figure 4 As shown, the driver 10 further includes a retaining spring 184, which is arranged between the bearing seat 183 and the outer ring 182 of the bearing 18 along the axial direction of the operating shaft 15. Thus, the bearing 18 is prevented from moving in the axial direction, and the axial stability of the bearing 18 is further improved.

[0047] In some embodiments, Figure 2 and Figure 3 As shown, the length of the second end 152 of the operating shaft 15 extending out of the housing 11 is greater than the length of the first end 151 of the operating shaft 15 extending out of the housing 11. Thus, the housing 11 of the driver 10 can be offset relative to the support 101 of the microscope 100, and the driver 10 can be conveniently installed on the support 101 of the microscope 100.

[0048] In some embodiments, Figure 1As shown, the housing 11 is configured to be fixedly connected to the support 101 of the microscope 100 at one side of the first end 151 of the operating shaft 15. Thus, the housing 11 can be conveniently installed to the support 101 of the microscope 100, simplifying the installation operation.

[0049] In some embodiments, Figure 2 As shown, the transmission assembly 17 includes: a gear 171, which is arranged in the middle of the operating shaft 15; a rack 172, which is fixedly connected to the sliding member 13; a first double gear 173 and a second double gear 174, which are drivably arranged between the gear 171 and the rack 172 and rotatably connected to the housing 11, wherein the first double gear 173 includes a first large gear and a first small gear, and the second double gear 174 includes a second large gear and a second small gear, the first large gear is meshed with the gear 171, the first small gear is meshed with the second large gear, and the second small gear is meshed with the rack 172. Thus, the transmission assembly 17 can realize multi-stage reduction transmission from the operating shaft 15 to the sliding member 13.

[0050] In some embodiments, Figure 1 As shown, the driver 10 further includes two handwheel assemblies 19, which are respectively drivably connected to the first end 151 and the second end 152 of the operating shaft 15. Thus, the operating shaft 15 is manipulated by the two handwheel assemblies 19, which can facilitate the operation of the operator.

[0051] In some embodiments, Figure 1 As shown, each of the two handwheel assemblies 19 includes a coarse adjustment handwheel 191 and a fine adjustment handwheel 192, and the coarse adjustment handwheel 191 and the fine adjustment handwheel 192 are simultaneously connected to the first end 151 or the second end 152 of the operating shaft 15 through a transmission mechanism, so that the sliding member 13 slides roughly or finely relative to the housing 11. In this way, the coarse adjustment or fine adjustment of the objective lens converter 103 of the microscope 100 in the Z direction can be achieved.

[0052] like Figure 1 and Figure 5 As shown, the microscope 100 according to an embodiment of the utility model includes: a bracket 101; a driver 10 according to any one of the embodiments of the first aspect of the utility model, wherein the bracket 101 has a first wall 1011 and a second wall 1012 relative to each other along the axial direction of the operating shaft 15, the shell 11 is fixedly connected to the first wall 1011, and the second end 152 of the operating shaft 15 is axially rotatably connected to the second wall 1012 via a bearing 18.

[0053] In the microscope 100 according to the embodiment of the present utility model, the first end 151 of the operating shaft 15 of the driver 10 extends out of the housing 11 and is rotatably connected to the housing 11, the second end 152 of the operating shaft 15 extends out of the housing 11 and is rotatably connected to the support 101 of the microscope 100, and the housing 11 of the driver 10 is connected to the support 101 of the microscope 100. That is, the first end 151 of the operating shaft 15 is supported to the support 101 of the microscope 100 through the housing 11, and the second end 152 is directly rotatably supported to the support 101 of the microscope 100. Thus, the operating shaft 15 is stably supported, and the bending generated on the operating shaft 15 when the operating shaft 15 is manipulated is reduced, thereby avoiding the displacement of the objective lens converter 103 caused thereby and significantly improving the drift of the image.

[0054] According to the following Figures 1 to 5 A driver 10 for a microscope 100 according to a specific embodiment of the present invention is described.

[0055] Figure 1 is a schematic diagram of a microscope 100 according to an embodiment of the present utility model. Figure 1 As shown, the driver 10 according to the embodiment of the present utility model includes a housing 11 , a sliding member 13 , an operating shaft 15 , a transmission assembly 17 and two hand wheel assemblies 19 .

[0056] The housing 11 is substantially box-shaped and has a first direction (eg, Figure 1 The first side wall 111 and the second side wall 112 are opposite to each other in the left and right direction (as shown in the figure), and along a second direction perpendicular to the first direction (for example, as shown in the figure), Figure 1 The third side wall 113 and the fourth side wall 114 are opposite to each other in the front-to-rear direction (as shown in FIG. 1 ), and a third direction perpendicular to the first direction and the second direction (for example, as shown in FIG. 1 ). Figure 1 The fifth side wall 115 and the sixth side wall 116 are shown in the top-to-bottom direction.

[0057] The operating shaft 15 extends substantially in the first direction, that is, the axial direction of the operating shaft 15 is substantially consistent with the first direction. The operating shaft 15 passes through the first side wall 111 and the second side wall 112 of the housing 11 in the first direction, and the first end 151 and the second end 152 of the operating shaft 15 extend out of the first side wall 111 and the second side wall 112 of the housing 11 respectively.

[0058] The housing 11 is configured to be fixedly connected to the support 101 of the microscope 100 at one side of the first end 151 of the operating shaft 15. For example, the first side wall 111 of the housing 11 (e.g., Figure 1 The left side wall shown) is fixedly connected to the support 101 of the microscope 100.

[0059] The third side wall 113 of the housing 11 (eg, Figure 1 Thus, the transmission assembly 17 disposed in the housing 11 can be exposed from the third side wall 113, thereby facilitating the installation and maintenance of the transmission assembly 17.

[0060] Two handwheel assemblies 19 are respectively connected to the two ends of the operating shaft 15. Each handwheel assembly 19 includes a coarse adjustment handwheel 191 and a fine adjustment handwheel 192, and the coarse adjustment handwheel 191 and the fine adjustment handwheel 192 are simultaneously connected to the first end 151 or the second end 152 of the operating shaft 15 through a transmission mechanism, so that the sliding member 13 slides relative to the housing 11 in a rough or fine manner.

[0061] It can be understood that the transmission mechanism has a first input end, a second input end and an output end. The output end of the transmission mechanism is connected to the first end 151 or the second end 152 of the operating shaft 15, the coarse adjustment hand wheel 191 is connected to the first input end of the transmission mechanism, and the fine adjustment hand wheel 192 is connected to the second input end of the transmission mechanism. In the transmission mechanism, the transmission ratio from the first input end to the output end is different from the transmission ratio from the second input end to the output end, thereby realizing the coarse adjustment and fine adjustment functions of the Z-axis driver 10.

[0062] The second end 152 of the operating shaft 15 is rotatably connected to the bracket 101 of the microscope 100 through the bearing 18. The bearing 18 is fixedly connected to the inner side of the microscope 100. Therefore, the bearing 18 cannot be seen from the outside of the microscope 100, making the appearance of the microscope 100 neat and beautiful.

[0063] Figure 2 is a schematic diagram of a driver 10 for a microscope 100 according to an embodiment of the present invention.

[0064] like Figure 2 As shown, the length of the second end 152 of the operating shaft 15 extending out of the housing 11 is greater than the length of the first end 151 of the operating shaft 15 extending out of the housing 11. Thus, the driver 10 can be offset mounted relative to the support 101 of the microscope 100, that is, the driver 10 can be offset mounted relative to the center of the support 101 of the microscope 100, so that the housing 11 of the driver 10 is closer to one side of the support 101 of the microscope 100, which facilitates the connection of the housing 11 of the driver 10 with one side of the support 101 of the microscope 100.

[0065] The sliding member 13 is substantially plate-shaped and extends along the third direction. The sliding member 13 is slidably connected to the fourth side wall 114 of the housing 11 to slide along the third direction. The sliding member 13 is configured to install the objective lens converter 103 of the microscope 100, thereby driving the objective lens converter 103 to move along the third direction. Therefore, the driver 10 for the microscope 100 according to the embodiment of the utility model can be called a Z-direction driver 10.

[0066] The transmission assembly 17 is drivably connected between the operating shaft 15 and the sliding member 13, so that when the operating shaft 15 rotates, the sliding member 13 is driven to slide relative to the housing 11 through the transmission assembly 17. The transmission assembly 17 includes a gear 171, a rack 172, a first double gear 173 and a second double gear 174. The gear 171 is arranged in the middle of the operating shaft 15. The gear 171 is fixedly connected to the sliding member 13. The first double gear 173 and the second double gear 174 are drivably arranged between the gear 171 and the rack 172 and are rotatably connected to the housing 11. The first double gear 173 includes a first large gear and a first small gear, and the second double gear 174 includes a second large gear and a second small gear, the first large gear is meshed with the gear 171, the first small gear is meshed with the second large gear, and the second small gear is meshed with the rack 172.

[0067] It can be understood that the outer diameter of the gear 171 is smaller than the outer diameter of the operating shaft 15 , and therefore the gear 171 is formed as a toothed groove on the operating shaft 15 surrounding the circumference of the operating shaft 15 .

[0068] The transmission assembly 17 further includes a first support shaft 175 and a second support shaft 176. The first support shaft 175 and the second support shaft 176 both extend in the first direction, that is, the first support shaft 175 and the second support shaft 176 are parallel to the operating shaft 15. The first support shaft 175 and the second support shaft 176 are closer to the fifth side wall 115 of the housing 11 relative to the operating shaft 15 along the third direction, that is, Figure 1 The first support shaft 175 and the second support shaft 176 are arranged above the operating shaft 15. The second support shaft 176 is closer to the fifth side wall 115 of the housing 11 along the third direction relative to the first support shaft 175, that is, Figure 1 The second support shaft 176 is shown arranged above the first support shaft 175 .

[0069] The first double gear 173 is rotatably connected to the housing 11 via a first support shaft 175 , and the second double gear 174 is rotatably connected to the housing 11 via a second support shaft 176 .

[0070] Therefore, the transmission assembly 17 realizes multi-stage reduction transmission between the operating shaft 15 and the sliding member 13 .

[0071] The slide 13 is provided with a mounting strip 131 extending in the second direction, the rack 172 is oriented in the third direction and the end of the rack 172 is fixedly connected to the end of the mounting strip 131. Thus, the cooperation between the rack 172 and the second pinion of the second double gear 174 is facilitated.

[0072] The fifth side wall 115 of the housing 11 is formed with an escape hole 117, which corresponds to the connection position between the rack 172 and the mounting bar 131. Thus, the installation and maintenance of the rack 172 and the mounting bar 131 are facilitated.

[0073] The housing 11 is further provided with a partition plate 118. A first end of the partition plate 118 is connected to the fifth side wall 115, and a second end thereof is connected to the sixth side wall 116. The partition plate 118 extends along the second direction, and divides the interior of the housing 11 into two subspaces arranged along the first direction, and the transmission assembly 17 is arranged in the subspace close to the second end 152 of the operating shaft 15 along the first direction. The first support shaft 175 and the second support shaft 176 are supported on the partition plate 118 and the second side wall 112 of the housing 11.

[0074] Figure 3 is another schematic diagram of the driver 10 for the microscope 100 according to an embodiment of the present invention.

[0075] like Figure 3 As shown, flanges 119 are formed at two edges of the first side wall 111 in the second direction, and the first side wall 111 of the housing 11 is connected to the bracket 101 of the microscope 100 through the flanges 119. Thus, the housing 11 of the driver 10 is connected to the bracket 101 of the microscope 100 at the first side wall 111, thereby simplifying the installation steps of the driver 10 to the bracket 101 of the microscope 100. In addition, the driver 10 is connected to the bracket 101 of the microscope 100 at the first side wall 111 of the housing 11, so that the driver 10 forms a cantilever beam-like structure relative to the bracket 101 of the microscope 100, and bending may occur at the second end 152 of the operating shaft 15 when the operating shaft 15 is manipulated, thereby causing the displacement of the objective lens converter 103 and the drift of the image.

[0076] The fourth side wall 114 of the housing 11 (eg, Figure 1 The front side wall 114 (shown in FIG. 1 ) forms a slide groove 120 extending along the third direction, and the sliding member 13 can be fitted into the slide groove 120 and slide in the slide groove 120. An opening is formed at the bottom of the slide groove 120 of the fourth side wall 114. Thus, the transmission assembly 17 disposed in the housing 11 can be exposed from the fourth side wall 114, thereby facilitating the installation and maintenance of the transmission assembly 17.
