Description

Technical Field

[0001] The invention relates to a dissecting table, in particular to a lifting dissecting table. Background Art

[0002] The lifting dissection table is usually composed of a base, a lifting device and a table panel. The traditional lifting device used in the dissection table includes a piston cylinder, a screw nut and a four-link lifting mechanism. Although these lifting devices can realize the lifting function of the table panel when in use, they are limited by the size of the dissection table base. When driving the table panel to lift, the lifting range of the above-mentioned lifting devices is also limited. For example, the length of the screw nut usually cannot be higher than the upper edge of the dissection table outer shell (equivalent to the outer box body described in this patent), otherwise it will be unsightly and affect the dissection operation. Therefore, the maximum lifting height of the table panel does not exceed the height of the dissection table outer shell. Due to the existence of the cylinder body, the telescopic distance of the piston rod of the piston cylinder is limited by the length of the piston cylinder body. Usually, the piston cylinder must also be set below the upper edge of the dissection table outer shell. Then the lifting height of the table panel still does not exceed the height of the dissection table outer shell. The four-link lifting mechanism has the problem of large installation space. It is set below the table panel and the table panel cannot sink into the dissection table outer shell. Therefore, how to further expand the lifting range of the dissection table panel has become a technical problem that needs to be solved urgently. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a lifting dissection table which can effectively expand the lifting range of the table panel.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is: a lifting dissection table, including a base and a table panel, the base is provided with two horizontally arranged transmission shafts in parallel, the two ends of the two transmission shafts are respectively rotatably connected to the two ends of the base, and a driving device is provided on the base at the same end of the two transmission shafts, the driving device is connected to the two transmission shafts for driving the two transmission shafts to rotate synchronously, a positive screw thread and a reverse screw thread are respectively provided at the two ends of any transmission shaft, the positive screw threads on the two transmission shafts are opposite to each other, the reverse screw threads are opposite to each other, and any positive screw thread A rotating shaft rotatably connected to the base is respectively arranged above the positive or negative screw teeth, the rotating shaft is arranged perpendicular to the transmission shaft and is fixedly connected to a turbine meshing with the positive or negative screw teeth below it, and a swing rod is also vertically connected to the rotating shaft, the two swing rods on the rotating shafts above the two positive screw teeth are parallel to each other and the free ends are fixedly connected to each other through a supporting rod, the two swing rods on the rotating shafts above the two negative screw teeth are also parallel to each other and the free ends are also fixedly connected to each other through a supporting rod, the two supporting rods swing synchronously in opposite directions driven by the turbine, and the table panel is placed on the two supporting rods.

[0005] As a preferred solution, the base includes a rectangular outer box body with an opening at the upper end and a rectangular inner box body with an opening at the upper end, the inner box body is fixedly arranged in the outer box body, and an annular cavity is formed between the inner box body and the outer box body, the axes of the two transmission shafts are parallel to the length direction of the outer box body and are respectively arranged in the cavities on both sides of the inner box body, the two ends of the transmission shaft are rotatably connected to the two ends of the outer box body, the four rotating shafts are respectively rotatably connected to the inner box body, one end of any rotating shaft extends into the cavity and is connected to the turbine, and the other end extends into the inside of the inner box body and is connected to the rocker arm, the length of the table panel is smaller than the inner length of the inner box body, and the width of the table panel is smaller than the spacing between the rocker arms at both ends of the support rod, and the table panel is located between the two rocker arms at both ends of the same support rod.

[0006] As a preferred solution, the driving device includes a driving shaft rotatably connected to the side wall of one end of the outer box body, the driving shaft is parallel to the transmission shaft, a driving sprocket is fixedly connected to the driving shaft, a synchronous sprocket is respectively provided on the two transmission shafts, the driving sprocket and the two synchronous sprockets are connected to each other through a chain, the driving shaft or the driving sprocket is connected to a power device, and the power device drives the driving shaft or the driving sprocket to rotate.

[0007] As a preferred solution, the support rod is a round rod, and a ball sleeve is sleeved on the support rod.

[0008] As a preferred solution, the turbine is fan-shaped.

[0009] The beneficial effects of the present invention are as follows: the present invention utilizes two supporting rods to lift the table panel, utilizes the transmission rod, the forward-spinning screw thread, the reverse-spinning screw thread and the turbine to drive the two pairs of rocker arms to swing up and down, drives the two supporting rods to move up and down, drives the table panel to rise and fall, and since the rocker arm's swing angle is controlled by the rotation of the turbine, theoretically, the rocker arm can swing from vertically downward to vertically upward, thereby realizing that the table panel's lifting range is twice the distance between the rotating shaft and the supporting rod. In this way, as long as the length of the rocker arm is greater than half the height of the base, the table panel's lifting range can exceed the base height. It can be seen that the lifting dissection table described in the present invention can effectively expand the lifting range of the table panel.

[0010] The present invention further configures the base into an inner box body and an outer box body, so that the cavity between the inner box body and the outer box body can be used to absorb harmful gases volatilized from the specimen or the preservative liquid. It only needs to provide an air suction device on the outer box body and cover the upper opening of the cavity with a perforated plate. This not only provides space for installing the transmission shaft and the turbine, but also can purify the air, thereby improving the safety of the operator.

[0011] The present invention adopts a chain to connect the driving sprocket and the two synchronous sprockets, which has a simple structure and low cost, and can effectively ensure the transmission accuracy and eliminate the cumulative error.

[0012] The present invention further sleeves a ball sleeve on the support rod, which can effectively reduce the friction damage on the lower surface of the table panel, reduce the lifting noise, and increase the service life of the lifting dissection table. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] like Figure 1~Figure 4The lifting dissection table shown includes a base 1 and a table panel 2, the base 1 includes a rectangular outer box body 101 with an opening at the upper end and a rectangular inner box body 102 with an opening at the upper end, the inner box body 102 is fixedly arranged in the outer box body 101, and an annular cavity 103 is formed between the inner box body 102 and the outer box body 101, two horizontally arranged transmission shafts 3 are arranged in parallel in the outer box body 101, the axial directions of the two transmission shafts 3 are parallel to the length direction of the outer box body 101 and are respectively arranged in the cavity 103 on both sides of the inner box body 102, the two ends of the two transmission shafts 3 are respectively rotatably connected to the two ends of the outer box body 101, and a driving device 4 is arranged on the outer box body 101 located at the same end of the two transmission shafts 3, the driving device 4 is connected to the two transmission shafts 3 for driving the two transmission shafts 3 to rotate synchronously, and a positive screw thread 5 and a reverse screw thread 6 are respectively arranged at the two ends of any transmission shaft 3. The two positive-rotating screw teeth 5 on the two transmission shafts 3 are opposite to each other across the inner box body 102, and the two reverse-rotating screw teeth 6 are opposite to each other across the inner box body 102. A rotating shaft 7 is rotatably connected to the side wall of the inner box body 102 above any positive-rotating screw tooth 5 or reverse-rotating screw tooth 6. The rotating shaft 7 is perpendicular to the transmission shaft 3. A turbine 8 meshing with the positive-rotating screw tooth 5 or reverse-rotating screw tooth 6 below it is arranged and fixedly connected to the rotating shaft 7. One end of any rotating shaft 7 extends into the cavity 103 and is connected to the turbine 8, and the other end extends into the inner box body 102 and is connected to the swing rod 9. The two swing rods 9 on the rotating shafts 7 above the two positive-rotating screw teeth 5 are parallel to each other and the free ends are fixedly connected to each other through a supporting rod 10. The two swing rods 9 on the rotating shafts 7 above the two reverse-rotating screw teeth 6 are also parallel to each other and the free ends are also fixedly connected to each other through a supporting rod 10. The two support rods 10 swing synchronously in opposite directions under the drive of the turbine 8.

[0021] The table panel 2 is placed on two supporting rods 10, the length of the table panel 2 is smaller than the inner length of the inner box body 102, and the width of the table panel 2 is smaller than the distance between the swing rods 9 at both ends of the supporting rods 10. The table panel 2 is located between the two swing rods 9 at both ends of the same supporting rod 10. When the two supporting rods 10 swing downward into the inner box body 102, the table panel 2 also drops into the inner box body 102.

[0022] The driving device 4 includes a driving shaft 401 rotatably connected to the side wall of one end of the outer box body 101, the driving shaft 401 is parallel to the transmission shaft 3, a driving sprocket 402 is fixedly connected to the driving shaft 401, and a synchronous sprocket 11 is respectively provided on the two transmission shafts 3. The driving sprocket 402 and the two synchronous sprockets 11 are connected to each other through a chain 403. The driving shaft 401 or the driving sprocket 402 is connected to a power device 404, and the power device 404 drives the driving shaft 401 or the driving sprocket 402 to rotate. The power device 404 can be a handle, or it can be an electric motor and a transmission pair.

[0023] The support rod 10 is a round rod, and a ball sleeve 12 is sleeved on the support rod 10. The turbine 8 is fan-shaped, and unused parts are omitted, thereby reducing costs and the demand for installation space.

[0024] The working principle of the present invention is: Figure 1~Figure 4 As shown, the table panel 2 of the lifting dissection table is used to store dissection targets. When dissection is not needed, the driving sprocket 402 is driven to rotate by the power device 404. The driving sprocket 402 drives the two synchronous sprockets 11 to rotate through the chain 403. The two synchronous sprockets 11 respectively drive the two transmission shafts 3 to rotate synchronously in the same direction. The positive screw teeth 5 and the reverse screw teeth 6 on the two transmission shafts 3 rotate with the transmission shaft 3 and drive the turbine 8 and the rotating shaft 7 to rotate. Since the positive screw teeth 5 and the reverse screw teeth 6 on the same shaft rotate in opposite directions, the turbine 8 and the rotating shaft 7 driven by the positive screw teeth 5 and the reverse screw teeth 6 rotate in opposite directions, which drives the two pairs of rocker arms to swing synchronously in opposite directions, swings the support rod 10 toward the inside of the inner box body 102, and the table panel 2 gradually descends until it is incorporated into the inner box body 102.

[0025] The inner box body 102 is filled with antiseptic liquid, which can provide good antiseptic protection for the specimen.

[0026] When the specimen needs to be dissected, the driving sprocket 402 is controlled to rotate in the opposite direction according to the above operation, so that the two support rods 10 can be gradually swung upward. The operator can turn off the driving device 4 at any time according to his own needs to keep the table panel 2 at a suitable height.

[0027] The above embodiments are only illustrative of the principles and effects of the invention, as well as some embodiments of its application, and are not intended to limit the invention. It should be pointed out that a person skilled in the art can make several modifications and improvements without departing from the inventive concept of the invention, and all of these belong to the protection scope of the invention.
