[0031] A microscope adjustable base, comprising:

[0032] A box-type base 1, a through slot 13 is provided on the top of the box-type base 1, a threaded rod 10 is rotatably installed at the bottom of the box-type base 1, a left-handed thread is provided on one side of the outer wall of the threaded rod 10, and a right-handed thread is provided on the other side of the outer wall of the threaded rod 10, and symmetrically distributed adjustment blocks 8 are sleeved on the outer wall of the threaded rod 10, a limiting mechanism is provided at the bottom of the inner wall of the box-type base 1, and a placement plate 4 is provided on the top of the box-type base 1;

[0033] The bottom of the placement plate 4 is hinged with symmetrically distributed connecting rods 12, which penetrate the interior of the through slot 13, and the end of the connecting rod 12 away from the placement plate 4 is hinged to the top of the corresponding adjustment block 8, a worm 2 is rotatably installed on one side of the interior of the box-type base 1, a worm wheel 5 is fixedly installed on the outer wall of one end of the threaded rod 10, and the worm wheel 5 is meshed with the worm 2, and the top end of the worm 2 penetrates one side of the top of the inner wall of the box-type base 1 and extends to one side above the top of the box-type base 1;

[0034] A handwheel 3 is fixedly installed on the top of the worm 2, and a plurality of limit rods 11 are fixedly installed on the bottom of the placement plate 4. The top of the box-type base 1 is provided with sliding holes 22 corresponding to the positions and quantities of the limit rods 11, and the sliding holes 22 are slidably connected with the limit rods 11. A positioning mechanism is arranged above one side of the box-type base 1.

[0035] An inspection door is provided on the front of the box-type base 1, and a handle 9 is fixedly installed on one side of the box-type base 1, so as to facilitate the inspection of the mechanical structure inside the base and the carrying of the base.

[0036] In one of the embodiments, the positioning mechanism includes a fixing hole 16, and the fixing hole 16 is opened above one side of the box-type base 1, the fixing hole 16 is connected to the inside of a sliding hole 22, a positioning rod 18 is slidably inserted on the fixing hole 16, a sliding groove 19 is opened on the upper side of the inner wall of the fixing hole 16, a slider 20 is fixedly installed on the outer wall of the positioning rod 18, and the slider 20 is slidably connected to the sliding groove 19, a spring 17 is fixedly connected between one side of the slider 20 and the inner wall of the sliding groove 19, a baffle 15 is fixedly installed on one end of the positioning rod 18, and an operating rod 14 is hinged on the top of the baffle 15, a tooth groove 21 is opened on the outer wall of a limiting rod 11, the other end of the positioning rod 18 is inclined, and the tooth groove 21 is clamped and adapted to the positioning rod 18, so as to achieve further limiting of the base after the height adjustment, thereby ensuring the stability of the base during use.

[0037] In one of the preferred embodiments, the limiting mechanism includes a limiting groove 6, and the limiting groove 6 is opened at the bottom of the box-type base 1. The bottoms of the two adjustment blocks 8 are fixedly installed with limiting blocks 7, and the limiting blocks 7 are slidably connected to the limiting groove 6, thereby realizing stable lateral movement of the adjustment blocks 8.

[0038] In one embodiment, a threaded hole matched with the threaded rod 10 is opened on one side of the adjusting block 8, and the adjusting block 8 is threadedly connected to the threaded rod 10 through the threaded hole opened on one side.

[0039] In one of the preferred embodiments, a non-slip pad is bonded to the top of the placement plate 4, which increases the friction of the placement plate 4 and makes the placement of the microscope more stable.

[0040] In one of the preferred embodiments, a placement hole 140 is provided on the box-type base 1, and the placement hole 140 matches the operating rod 14. After one end of the operating rod 14 is inserted into the placement hole 140, the positioning rod 18 is disengaged from the interior of the corresponding tooth groove 21, and the positioning rod 18 cannot automatically fit into the interior of the tooth groove 21.

[0041] The working principle of the utility model is as follows: when the base is in use, the box-type base 1 is directly placed on the workbench, and then the height of the base is adjusted. The operator directly turns the handwheel 3, and the rotation of the handwheel 3 drives the worm 2 to rotate. Through the meshing of the worm 2 and the worm wheel 5, the worm wheel 5 drives the threaded rod 10 to rotate. Through the thread transmission of the left-handed thread and the right-handed thread on the threaded rod 10, and the sliding relationship between the adjustment block 8 and the limit block 7 and the limit groove 6, the two adjustment blocks 8 can move relative to each other or move oppositely. When the two adjustment blocks 8 move relative to each other, the angle between the two connecting rods 12 will be reduced and the placement plate 4 will be lifted upward. When the placement plate 4 moves upward, it will drive the limit rod 11 to slide on the sliding hole 22. One of the limit rods 11 will contact the inclined end of the positioning rod 18 during the upward sliding process. With the cooperation of the spring 17, the limit rod 11 will automatically pop out and then engage with the tooth groove 21 at the corresponding position during the rising process. At the same time, the sliding connection between the limit rod 11 and the sliding hole 22 ensures the stability of the placement plate 4 during the vertical movement. When the placement plate 4 is adjusted to a specified height, the microscope can be directly placed on the top of the placement plate 4 for use. At this time, due to the engagement between the tooth groove 21 and the positioning rod 18, the limit rod 11 can be vertically moved. The downward moving direction of the moving position is locked, and even if the height adjustment structure fails, the stability of the placement plate 4 at the specified height can be ensured. In addition, the height adjustment structure adopts the meshing transmission of the worm 2 and the worm wheel 5. The self-locking property of the worm 2 and the worm wheel 5 can also ensure the stability of the placement plate 4 during use. When the placement plate 4 moves downward, the limit of the limit rod 11 by the positioning mechanism must be released first, and the operator directly pulls the operating rod 14. The operating rod 14 drives the positioning rod 18 to disengage from the corresponding tooth groove 21 through the baffle 15. At this time, the slider 20 will follow the movement of the positioning rod 18 to squeeze the spring 17, and then After that, the operating rod 14 is rotated and one end of the operating rod 14 is inserted into the placement hole 140 under the elastic action of the spring 17, so that the operating rod 14 is fixed on the side of the box-type base 1. At this time, the positioning rod 18 cannot be automatically inserted into the inside of the tooth groove 21, and the operator does not need to manually control the position of the positioning rod 18 all the time. Then the operator directly rotates the hand wheel 3 to make the two adjustment blocks 8 move oppositely, so that the placement plate 4 can be moved downward. First, the adjustment method of the base is manual, which means that it can be used at any time without external power supply, so that it is not restricted by external energy, and it is highly practical, and the manufacturing cost of the base is also reduced. Secondly, the positioning mechanism of the base is simple and efficient. When the placement plate 4 needs to be adjusted upward, the user does not need to perform any operation on the positioning mechanism, which is very convenient. And when the position of the placement plate 4 needs to be adjusted downward, the user only needs to simply operate the operating rod 14 so that the positioning rod 18 cannot be automatically inserted into the inside of the tooth groove 21, and the downward displacement operation of the placement plate 4 can be easily adjusted.This design avoids the need for continuous manual operation of the positioning mechanism throughout the entire operation process, greatly improving the convenience and efficiency of operation.

[0042] An inspection door is provided on the front of the box-type base 1 to facilitate inspection and maintenance of the mechanical structure inside the box-type base 1 . The handle 9 is provided to facilitate carrying the box-type base 1 .

[0043] Secondly, the utility model patent allows the microscope placed on the placement plate 4 to be operated only after the height of the base is adjusted, or the microscope can be placed on the placement plate 4 after the height is adjusted. Therefore, it will not affect the normal use of the microscope, nor does it need to fix the placement plate and the microscope, nor will it affect the stability of the microscope itself.

[0044] Secondly, the user can also manually pull the operating rod 14 to prevent the positioning rod 18 from automatically being inserted into the tooth groove 21 .

[0045] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
