Examples

Referring to fig. 1, a multifunctional observation device for pathological diagnosis includes a base 1, a lens frame 2 disposed on the base 1, and an objective table 3, wherein a lens 4 is mounted on the lens frame 2, a support rod 5 is further disposed on the base 1, and a lighting lamp 6 is disposed on the support rod 5.

In consideration of the fact that the objective table 3 is lifted by matching of the motor and the ball screw in the prior art, the manufacturing cost is high, and the objective table 3 cannot be lifted without a power supply, so that certain use limitation exists. For this purpose, this embodiment provides a new embodiment, namely, a first screw 7 is arranged below the object stage 3; one end of the first screw 7 is rotatably connected with the objective table 3, and the other end of the first screw extends into the base 1 along the vertical direction; the outer wall of the first screw rod 7 is sleeved with a first rotating sleeve 8, the outer wall of the first rotating sleeve 8 is rotatably connected with the base 1 through a bearing, and the inner wall of the first rotating sleeve 8 is in threaded connection with the first screw rod 7.

Through the above arrangement, when the operation is performed, an operator rotates the first rotating sleeve 8 through the knob, so that the first rotating sleeve 8 drives the first screw rod 7 to rotate, and further the first screw rod 7 extends to reciprocate in the vertical direction, and the object stage 3 is driven to lift. Compared with the prior art, the structure is simpler, adopts the screw rod to realize adjusting the height of objective table 3, adjusts the precision height, and adopts the first mode of rotating sleeve 8 of artifical knob to realize the lift of objective table 3, easy operation has reduced the cost when the device preparation, has improved the practicality of device simultaneously, also can go up and down to operate under the condition that does not have the power.

Meanwhile, the existing lens frame 2 also has certain limitations in adjustment. Therefore, in the embodiment, the lens frame 2 is connected with the hose 9, the lens frame 2 can be turned over in a vertical plane through the hose 9, so that the angle of the lens frame 2 can be adjusted and the lens frame 2 can be accommodated conveniently, the end of the hose 9 is connected with the fixed seat 10, and the second screw 11 is arranged below the fixed seat 10; one end of the second screw 11 is rotatably connected with the fixed seat 10, and the other end of the second screw extends into the base 1 along the vertical direction; the 11 outer wall cover of second screw rod is equipped with second and rotates sleeve 12, and second rotates sleeve 12 outer wall and passes through the bearing rotation with base 1 and be connected, and second rotates sleeve 12 inner wall and 11 threaded connection of second screw rod.

As can be seen from the above description, in this embodiment, the same lifting mechanism as the objective table 3 is also adopted for the lens frame 2 to drive the lens frame 2 to lift, that is, during operation, the second rotating sleeve 12 is turned by the knob to drive the second screw 11 to reciprocate along the vertical direction, so as to drive the lens frame 2 to lift, so that the lens frame 2 can be adjusted to the optimal height position as required during actual use, and an operator can observe conveniently.

In addition, in order to improve the efficiency when adjusting the heights of the object stage 3 and the lens frame 2, the observation device of the embodiment further comprises a driving mechanism, wherein the driving mechanism comprises a rotating shaft 13 and a transmission component, and the rotating shaft 13 is positioned between the first screw 7 and the second screw 11; the rotating shaft 13 is arranged along the vertical direction and is rotationally connected with the base 1; the rotating shaft 13 drives the first rotating sleeve 8 and the second rotating sleeve 12 to rotate in the same direction through the transmission assembly, and the threads of the first screw 7 are opposite to those of the second screw 11. Specifically, the transmission assembly includes a main gear 14 sleeved on the outer wall of the rotating shaft 13, a first pinion 15 is sleeved on the outer wall of the first rotating sleeve 8, a second pinion 16 is sleeved on the outer wall of the second rotating sleeve 12, and the main gear 14 is respectively engaged with the first pinion 15 and the second pinion 16.

With the above arrangement, when the height of the objective table 3 and the lens frame 2 needs to be adjusted, the main gear 14 is driven to coaxially rotate by rotating the rotating shaft 13, the main gear 14 drives the first pinion 15 and the second pinion 16 to rotate in the same direction, so that the first rotating sleeve 8 and the second rotating sleeve 12 are respectively driven to rotate in the same direction by the first pinion 15 and the second pinion 16, and since the threads on the first screw 7 and the second screw 11 are reversed, the second screw 11 drives the lens frame 2 to move upwards when the objective table 3 is driven by the first screw 7 to move downwards; on the contrary, when the first screw 7 drives the object stage 3 to move upwards, the second screw 11 drives the lens frame 2 to move downwards. And then realize making between objective table 3 and the lens frame 2 be close to each other or keep away from each other in the shortest time, efficiency when having improved the lift of actual operation objective table 3 and lens frame 2.

In this embodiment, the bottom ends of the first screw 7 and the second screw 11 are both provided with a limiting block 17, so as to limit the maximum distance of the first screw 7 and the second screw 11, and avoid the separation of the first screw 7 from the first rotating sleeve 8 and the separation of the second screw 11 from the second rotating sleeve 12.

In this embodiment, in order to facilitate the rotation of the rotating shaft 13, one end of the rotating shaft 13 extends to the inside of the base 1 and then is connected with the base 1 in a rotating manner, the other end of the rotating shaft 13 is provided with a rotating handle 18, and the outer wall of the rotating handle 18 is provided with anti-slip lines, so that the situation of hand slip during operation is avoided.
