Description

Technical Field

[0001] This utility model relates to the field of dissection table technology, and in particular to a double-lift dissection table. Background Technology

[0002] Dissection tables are a common tool in medical laboratories and operating rooms. They are mainly used for dissection, surgery, and research. Because the objects to be dissected need to be preserved well, they need to be soaked in formalin, which has a strong odor and a strong taste reaction.

[0003] Patent No. 202410594104.3 discloses a movable dissection table. The dissection table has a lifting cylinder inside the annular protrusion that drives the support frame to rise and fall. The support frame is slidably mounted on the guide column. In this way, the force that the dissection table bears when it is raised and lowered is borne by the guide column. When it is raised to the highest and lowest positions, it is locked by the self-locking of the lifting cylinder. When the load is too heavy, it will affect the service life of the lifting cylinder. When the lifting cylinder fails, it cannot be supported in time. At the same time, the range supported by the annular protrusion is too small, resulting in poor stability of the dissection table when it is raised and lowered. Utility Model Content

[0004] The technical problem to be solved by this utility model is: a dual-lift dissection table, which can adjust the dissection table base as a whole and adjust the dissection table surface individually, with stable lifting and reliable support, and improved efficiency.

[0006] As a preferred embodiment, the outer frame includes an outer upper frame, an outer lower frame, and an outer perimeter plate, which are sequentially connected and fixed. The inner frame includes an inner upper frame, and the lifting drive adjustment device includes a lifting electric cylinder, which is fixed on the outer lower frame and connected to the inner upper frame. When the inner frame is at its lowest position, the inner upper frame presses against the outer upper frame, and the inner upper frame is fixedly connected to the dissection table base.

[0007] As a preferred embodiment, the inner frame further includes an inner lower frame, which is fixedly connected to the inner upper frame via a connecting rod. The inner lower frame presses against the outer lower frame, and the outer upper frame is provided with a limiting pad to limit the lifting and lowering of the connecting rod.

[0008] As a preferred embodiment, a corrugated pipe for dust prevention is also provided between the dissection table base and the outer frame.

[0009] As a preferred embodiment, the table lifting device includes a pair of first swing arms and a pair of second swing arms mounted on the dissection table base within the storage cavity, both swinging in opposite directions. The first and second swing arms are driven by a synchronous swinging force device to swing in opposite directions synchronously. The dissection table base also includes a support frame on which the dissection table is placed. The dimensions of the support frame are adapted to the dimensions of the storage cavity. The side of the support frame has a first hole and a second hole. Each of the free ends of the first swing arms has a first movable pin, and each of the free ends of the second swing arms has a second movable pin. The first movable pin is constrained within the first hole, and the second movable pin is constrained within the second hole. When the synchronous swaying force device drives the first and second swing arms to sway synchronously in opposite directions, it causes the support frame to rise and fall between the receiving position and the storage position. In the storage position, the support frame is located inside the storage cavity, and the first and second movable pins abut against the opposite edge of the first and second holes, respectively. In the receiving position, the support frame is above the storage cavity, and the first and second movable pins abut against the opposite edge of the first and second holes, respectively.

[0010] As a preferred embodiment, the storage cavity is a cuboid storage cavity, and the corresponding support frame is a rectangular support frame. The rectangular support frame includes a rectangular enclosure, and a reinforcing connecting rod is provided inside the enclosure. The first hole and the second hole are provided on the side wall of the enclosure.

[0011] As a preferred embodiment, the first hole and the second hole are located on the two long sides of the frame and are arranged opposite to each other. The first movable pins on the free ends of a pair of first swing rods are connected to each other to form a first synchronous link, and the first synchronous link passes through the first hole on the two long sides. The second movable pins on the free ends of a corresponding pair of second swing rods are connected to each other to form a second synchronous link, and the second synchronous link passes through the second hole on the two long sides.

[0012] As a preferred embodiment, the first and second synchronous connecting rods have the same structure and installation method. The first synchronous connecting rod includes a synchronous connecting rod body with a circular cross-section. The two ends of the synchronous connecting rod body are provided with cylindrical mating shoulders. The diameter of the mating shoulders is smaller than the diameter of the synchronous connecting rod body. The mating shoulders pass through the first hole and are connected to the free end of the first swing rod. A side limiting sleeve is provided on the mating shoulders between the long side of the first swing rod and the frame.

[0013] As a preferred embodiment, a bushing is rotatably fitted on the mating shoulder, and the bushing mates with the first hole.

[0014] As a preferred embodiment, the upper surface of the support frame is also provided with guide rollers to facilitate the sliding of the dissection table; the support frame is also provided with a panel positioning structure for positioning the dissection table.

[0015] After adopting the above technical solution, the effect of this utility model is as follows: The double-lift dissection table includes a dissection table base, a dissection table surface is provided inside the storage cavity, an outer frame is provided below the dissection table base, and an inner frame supporting the dissection table base is installed in a lifting manner within the outer frame. The inner frame is raised and lowered on the outer frame via multiple lifting drive adjustment devices. The lifting drive adjustment devices are fixed to the outer frame and connected to the inner frame. When the inner frame is at its lowest position, it presses against the outer frame. A cover plate covering the storage cavity is also provided on the dissection table surface. Firstly, the lifting drive adjustment... The device drives the inner frame to rise, which in turn raises and lowers the dissection table base, positioning the dissection table surface at a suitable height. When the dissection table surface returns to its original position, the inner frame is driven to descend, pressing against the outer frame to ensure the stability of the dissection table base. This dissection table allows for overall adjustment of the dissection table surface, with stable raising and lowering, reliable support, and improved efficiency. After the overall height of the dissection table base is changed, experiments can be performed standing or sitting. When sitting, the area between the bottom of the dissection table base and the outer frame can accommodate the operator's knees due to the raised dissection table base, making operation more comfortable.

[0016] Furthermore, since the outer frame includes an outer upper frame, an outer lower frame, and an outer perimeter plate, which are sequentially connected and fixed, and the inner frame includes an inner upper frame, the lifting drive adjustment device includes a lifting electric cylinder, which is fixed on the outer lower frame and connected to the inner upper frame. When the inner frame is at its lowest position, the inner upper frame presses against the outer upper frame, and the inner upper frame is fixedly connected to the dissection table base. The outer lower frame ensures accurate installation of the lifting electric cylinder and provides stability when lifting the inner upper frame. Moreover, the inner upper frame can press against the outer upper frame, reducing the force borne by the lifting electric cylinder, improving stability, and extending the service life of the lifting electric cylinder.

[0017] Furthermore, the inner frame also includes an inner lower frame, which is fixedly connected to the inner upper frame via a connecting rod. The inner lower frame presses against the outer lower frame, and the outer upper frame is provided with a limiting pad to limit the lifting and lowering of the connecting rod. By pressing the inner lower frame against the outer lower frame, the stability of the dissection table base can be further improved. At the same time, the limiting pad can ensure that the inner upper frame will not shake during the lifting and lowering process, thus ensuring stable lifting and lowering.

[0018] Furthermore, a corrugated pipe is provided between the dissection table base and the outer frame to block dust; the corrugated pipe can rise and fall with the dissection table base to protect the internal structure.

[0019] Furthermore, the table lifting device includes a pair of first swing arms and a pair of second swing arms mounted on the dissection table base within the storage cavity. The first and second swing arms are driven by a synchronous swaying force device to sway synchronously in opposite directions. The dissection table base also includes a support frame on which the dissection table is placed. The size of the support frame is adapted to the size of the storage cavity. The side of the support frame has a first hole and a second hole. Each free end of the first swing arms has a first movable pin, and each free end of the second swing arms has a second movable pin. The first movable pin is constrained within the first hole, and the second movable pin is constrained within the second hole. When the synchronous swaying force device drives the first and second swing arms to sway synchronously in opposite directions, it causes the support frame to rise and fall between the receiving position and the storage position. In the storage position, the support frame is located within the storage cavity, and the first movable pin... The first and second movable pins abut against the opposite edges of the first and second holes, respectively. In the receiving position, the support frame is above the storage cavity, and the first and second movable pins abut against the opposite edges of the first and second holes, respectively. Therefore, when the first and second swing arms of the lifting dissection table swing in opposite directions simultaneously, the first and second movable pins slide within the first and second holes, thereby driving the support frame to rise and fall. When the support frame rises to the receiving position, the first or second movable pin abuts against the edge of the first or second hole, effectively preventing the support frame from moving and ensuring reliable support of the dissection table surface. When storage is required, the first and second swing arms swing, causing the support frame to descend and sink into the storage cavity. Therefore, this dissection table utilizes the support frame to facilitate the entry and exit of the dissection table surface, ensuring it is always supported by the support frame during entry and exit, preventing any suspension and saving manpower. It is also suitable for automated entry and exit operations of the dissection table surface.

[0020] Furthermore, since the storage cavity is a cuboid storage cavity, the corresponding support frame is a rectangular support frame. The rectangular support frame includes a rectangular enclosure, and a reinforcing connecting rod is provided inside the enclosure. The first hole and the second hole are provided on the side wall of the enclosure. The reinforcing connecting rod can improve the strength of the support frame.

[0021] Furthermore, since the first and second holes are located on the two long sides of the frame and are positioned opposite each other, the first movable pins on the free ends of a pair of first swing arms are connected to each other to form a first synchronizing link, which passes through the first hole on the two long sides; correspondingly, the second movable pins on the free ends of a pair of second swing arms are connected to each other to form a second synchronizing link, which passes through the second hole on the two long sides; the first and second synchronizing links can further ensure the synchronicity of the pair of first swing arms and the pair of second swing arms. At the same time, the first and second synchronizing links pass through the first and second holes, thereby better supporting the support frame and further ensuring the stability of the support frame.

[0022] Furthermore, since the first and second synchronous connecting rods have the same structure and installation method, the first synchronous connecting rod includes a synchronous connecting rod body with a circular cross-section. The two ends of the synchronous connecting rod body are provided with cylindrical mating shoulders. The diameter of the mating shoulders is smaller than the diameter of the synchronous connecting rod body. The mating shoulders pass through the first hole and are connected to the free end of the first swing rod. A side limiting sleeve is provided on the mating shoulders between the long side of the first swing rod and the frame. The mating shoulders and the side limiting sleeve can effectively constrain the first swing rod and the frame.

[0023] Furthermore, since a bushing is rotatably fitted on the shoulder of the mating shaft, and the bushing mates with the first hole, the bushing can facilitate the movement of the first synchronizing link within the first hole and reduce friction.

[0024] Furthermore, the upper surface of the support frame is also provided with guide rollers to facilitate the sliding of the dissection table; the support frame is also provided with a panel positioning structure for positioning the dissection table; the guide rollers can facilitate the sliding of the dissection table in and out, making the movement smoother; at the same time, the panel positioning structure can position the dissection table to ensure that the dissection table is accurately placed in the designated position of the support frame.

[0032] The present invention will be further described in detail below through specific embodiments.

[0033] like Figures 1 to 5 As shown, a dual-lift dissection table includes a dissection table base 1, a storage cavity 3 on the dissection table base 1, and a dissection table surface 2 on the dissection table base 1. The dissection table surface 2 is driven by a table surface lifting device. An outer frame 41 is provided below the dissection table base 1. An inner frame supporting the dissection table base 1 is installed in the outer frame 41. The inner frame is raised and lowered on the outer frame 41 by multiple lifting drive adjustment devices. The lifting drive adjustment devices are fixed on the outer frame 41 and connected to the inner frame. When the inner frame is in the lowest position, the inner frame presses on the outer frame 41. A cover plate 15 covering the storage cavity 3 is also provided on the dissection table surface 2.

[0034] like Figure 2As shown, the outer frame 41 includes an outer upper frame 16, an outer lower frame 17, and an outer perimeter plate 18. The outer upper frame 16, the outer perimeter plate 18, and the outer lower frame 17 are sequentially connected and fixed. The inner frame includes an inner upper frame 19. The lifting drive adjustment device includes a lifting electric cylinder 20. The lifting electric cylinder 20 is fixed on the outer lower frame 17 and connected to the inner upper frame 19. When the inner frame 19 is in its lowest position, the inner upper frame 19 presses against the outer upper frame 16. The inner upper frame 19 is fixedly connected to the dissection table base 1. The lifting electric cylinder 20 is equipped with... There are four, with the outer frame 41 and the inner frame both being cuboids. The four lifting cylinders 20 are fixedly installed on the four corners of the outer lower frame 17 and connected to the four corners of the inner upper frame 19. This ensures that the lifting cylinders 20 are stably supported and can also be lifted stably when lifting the inner upper frame 19. Furthermore, the inner upper frame 19 can press against the outer upper frame 16, reducing the force on the lifting cylinders 20, improving stability, and extending the service life of the lifting cylinders 20. Of course, the lifting drive adjustment device can also use linear motors or other linear drive devices.

[0035] In this embodiment, the inner frame also includes an inner lower frame 21, which is fixedly connected to the inner upper frame 19 via a connecting rod 22. The inner lower frame 21 presses against the outer lower frame 17. The outer upper frame 16 is provided with limiting pads 23 for limiting the lifting and lowering of the connecting rod 22. Multiple limiting pads 23 are provided and are fixedly installed on the outer upper frame 16 by bolts. They abut against the connecting rod 22 on the outer upper frame 16 and are located around the inner upper frame 19, effectively limiting the movement. The limiting pads are made of nylon, which has good wear resistance and cushioning effect, improving the performance. The inner lower frame 21 pressing against the outer lower frame 17 can further improve the stability of the dissection table base 1. At the same time, the limiting pads 23 can ensure that the inner upper frame 19 will not shake during the lifting and lowering process, ensuring the stability of the dissection table 2 during lifting and lowering.

[0036] Furthermore, a corrugated pipe 24 for dust prevention is provided between the dissection table base 1 and the outer frame 41; the corrugated pipe 24 can rise and fall with the dissection table base 1 to protect the internal structure.

[0037] like Figure 3 and Figure 4As shown, the dissection table base 1 is provided with a storage cavity 3. The table lifting device includes a pair of first swing rods 6 and a pair of second swing rods 5 mounted on the dissection table base 1 within the storage cavity 3. The pair of first swing rods 6 and the pair of second swing rods 5 are driven by a synchronous swing force device to swing synchronously in opposite directions. The dissection table base 1 also includes a support frame 4, on which the dissection table 2 is placed. The size of the support frame 4 is adapted to the size of the storage cavity 3. The side of the support frame 4 is provided with a first hole 44 and a second hole 43. The free ends of the pair of first swing rods 6 are each provided with a first movable pin, and the free ends of the pair of second swing rods 5 are each provided with a first movable pin. A second movable pin is provided. The first movable pin is constrained within the first slot 44, and the second movable pin is constrained within the second slot 43. When the synchronous swaying force device drives the first swing arm 6 and the second swing arm 5 to sway synchronously in opposite directions, it causes the support frame 4 to rise and fall between the receiving position and the storage position. In the storage position, the support frame 4 is located within the storage cavity 3, and the first and second movable pins respectively abut against the opposite edges of the first slot 44 and the second slot 43. In the receiving position, the support frame 4 is above the storage cavity 3, and the first and second movable pins respectively abut against the first slot 44 and the second slot 43. 43 on the opposite side edge; the dissection table base 1 includes an outer box 101 and an inner box 102, the storage cavity 3 is disposed on the inner box 102, an installation space is provided between the outer box 101 and the inner box 102, the outer box 101 is fixedly installed on the inner upper frame 19, a pair of first swing rods 6 are respectively rotatably mounted on the side wall of the inner box 102 through a first hinge shaft and are arranged opposite to each other, similarly a pair of second swing rods 5 are respectively rotatably mounted on the side wall of the inner box 102 through a second hinge shaft and are located opposite to each other, the first swing rods 6 and the second swing rods 5 are respectively located at different ends of the inner box 102, when the first swing rods 6 and the second swing rods 5 of the lifting dissection table swing in opposite directions synchronously, the first movable pin shaft The first and second movable pins slide within the first hole 44 and the second hole 43, thereby driving the support frame 4 to rise and fall. When the support frame 4 rises to the receiving position, the first or second movable pin will abut against the edge of the first hole 44 or the second hole 43, effectively preventing the support frame 4 from moving and ensuring reliable support for the dissection table 2. When storage is required, the first swing arm 6 and the second swing arm 5 swing to drive the support frame 4 to descend and sink into the storage cavity 3. Therefore, the dissection table can better facilitate the entry and exit of the dissection table 2 by utilizing the support frame 4. During entry and exit, it is always supported by the support frame 4 and will not be suspended, thus saving manpower. It is also suitable for automated entry and exit operations of the dissection table 2.

[0038] In this embodiment, the receiving position and storage position are defined manually. When the dissection table 2 is placed on the support frame 4, the support frame 4 descends into the storage cavity 3 and can be stored. Therefore, the storage position is determined according to the storage position. When it is necessary to conduct dissection experiments or remove human specimens, the support frame 4 rises to the receiving position. At this time, the dissection table 2 is slightly higher than the upper opening of the dissection table base 1, which facilitates the removal of the dissection table 2.

[0039] The synchronous oscillating force device in this embodiment includes two drive shafts 10 rotatably installed in the mounting space between the outer housing 101 and the inner housing 102. Each drive shaft 10 is provided with two worm gear segments 11 with opposite thread directions. Correspondingly, the first hinge shaft and the second hinge shaft are respectively fixed with worm wheels 9 that cooperate with the corresponding worm gear segments 11. The ends of the two drive shafts 10 are respectively fixed with sprockets 12, and the drive shafts 10 are driven to rotate synchronously by a motor and a chain. The rotation of the drive shafts 10 drives the worm gear segments 11 to rotate, which in turn drives the worm wheels 9 to rotate. The worm wheels 9 and worm gear form a self-locking mechanism, so that the first swing arm 6 and the second swing arm 5 can swing to a designated position and stop at that position, which can also drive the dissection table 2 to rise and fall.

[0040] In this embodiment, the storage cavity 3 is a cuboid storage cavity 3, and the corresponding support frame 4 is a rectangular support frame 4. The rectangular support frame 4 includes a rectangular frame 41, and a reinforcing connecting rod 2242 is provided inside the frame 41. The first hole 44 and the second hole 43 are provided on the side wall of the frame 41. The rectangular support frame 4 is lifted and installed inside the inner box 102. The reinforcing connecting rod 2242 can improve the strength of the support frame 4 and facilitate the support of the dissection table 2.

[0041] Furthermore, the first hole and the second hole 43 are provided on the two long sides of the frame 41 and are arranged opposite to each other. The first movable pins on the free ends of the pair of first swing rods 6 are connected to each other to form a first synchronous link 8, which passes through the first hole 44 on the two long sides. The second movable pins on the free ends of the corresponding pair of second swing rods 5 are connected to each other to form a second synchronous link 7, which passes through the second hole 43 on the two long sides. The first synchronous link 8 and the second synchronous link 7 can further ensure the synchronicity of the pair of first swing rods 6 and the pair of second swing rods 5. At the same time, the first synchronous link 8 and the second synchronous link 7 pass through the first hole 44 and the second hole 43, which can better support the support frame 4 and further ensure the stability of the support frame 4.

[0042] Of course, structural deformation can also be made in this embodiment. The first swing rod 6 and the second swing rod 5 can be swung and installed on the short side wall of the inner box 102. Then the first hole 44 and the second hole 43 are set on the two short sides of the frame 41, which can also realize the lifting and lowering of the support frame 4.

[0043] like Figure 4 and Figure 5 As shown, the first synchronous link 8 and the second synchronous link 7 have the same structure and installation method. The first synchronous link 8 includes a synchronous link body with a circular cross-section. The two ends of the synchronous link body are provided with cylindrical mating shoulders 81. The diameter of the mating shoulders 81 is smaller than the diameter of the synchronous link body. The mating shoulders 81 pass through the first hole 44 and are connected to the free end of the first swing rod 6. A side limiting sleeve 14 is provided on the mating shoulders 81 between the long side of the first swing rod 6 and the frame 41. The second synchronous link 7 also has a circular cross-section. The two ends of the second synchronous link 7 are also provided with mating shoulders 81. The mating shoulders 81 are provided with corresponding side limiting sleeves 14. The mating shoulders 81 and the side limiting sleeves 14 can effectively constrain the first swing rod 6 and the frame 41. The same applies to the second swing rod 5.

[0044] Furthermore, a bushing is rotatably fitted on the mating shoulder 81, and the bushing mates with the first hole 44; this bushing can facilitate the movement of the first synchronous connecting rod 8 within the first hole 44 and reduce friction. Of course, the bushing can also be replaced with a bearing.

[0045] like Figure 4 and Figure 5 As shown, at least two limiting plates 25 are fixedly installed on the support frame 4. The lower ends of the two limiting plates 25 are lower than the lower end of the support frame 4, and the two limiting plates 25 are respectively limited and matched with the inner wall opposite to the storage cavity 3.

[0046] The limiting plate 25 is L-shaped and is fixed at the right angle of the support frame 4. The limiting plate 25 has vertical slots 26, and is fixed to the support frame 4 by bolts constrained within these slots. When the support frame 4 is inside the storage cavity 3, the limiting plate 25 also sinks into the storage cavity 3. When the support frame 4 rises to the receiving position, the lowest point of the limiting plate 25 has not yet left the storage cavity 3. Therefore, when the dissection table 2 is pushed or pulled in and out, the limiting plate 25 is still limited by the side wall of the storage cavity 3, ensuring the stability of the support frame 4 and preventing wobbling.

[0047] In this embodiment, the upper surface of the support frame 4 is also provided with guide rollers to facilitate the sliding of the dissection table 2; the support frame 4 is also provided with a panel positioning structure for positioning the dissection table 2; in this embodiment, preferably, four elastically retractable positioning balls 13 are provided on the upper surface of the support frame 4 and are respectively located at the four corners of the support frame 4. Correspondingly, two positioning grooves that cooperate with the positioning balls 13 are provided at the bottom of the dissection table 2. When the dissection table 2 enters the support frame 4, the bottom of the dissection table 2 will squeeze the positioning balls 13 and contract downwards. When the dissection table 2 moves into place, the positioning grooves correspond to the positions of the positioning balls 13. Thus, under the elastic force of the spring, the positioning balls 13 will enter the positioning grooves to achieve positioning. When the dissection table 2 needs to be moved out, the force of the movement will compress the positioning ball 13, thus facilitating its removal. The spring-loaded positioning ball 13 can be purchased directly from the market, such as the spring-loaded ball from Fulibaiya. All the guide rollers support the dissection table 2 together. When the positioning ball 13 bounces up, its upper surface is higher than the guide rollers. Since the guide rollers are an existing structure, they are not shown in the figure.

[0048] The working principle of this embodiment is as follows: First, the lifting cylinder 20 drives the inner upper frame 19 to lift and lower, thereby controlling the overall lifting and lowering of the outer casing 101 for initial height adjustment. Then, the two drive shafts 10 are driven to rotate by the motor, which in turn drives the first swing arm 6 and the second swing arm 5 to deflect through the worm gear 9 and worm mechanism. At this time, the first synchronous connecting rod 8 and the second synchronous connecting rod 7 will move in opposite directions simultaneously. When the first swing arm 6 and the second swing arm 5 swing upward relative to each other, the support frame is higher than the opening plane height of the outer casing 101. At this time, the support frame 4 is just in the receiving position, and the dissection table 2 can smoothly enter the support frame 4 from the side or the end. During the entry process, the bottom of the dissection table 2 will squeeze the positioning ball 1. 3. Compress it, and then the bottom of the dissection table 2 is supported by the guide roller. When it moves into place, the positioning groove at the bottom of the dissection table 2 cooperates with the positioning ball 13. At this time, the positioning ball 13 bounces up and enters the positioning groove to achieve positioning. After the dissection experiment teaching is completed, the first pendulum 6 and the second pendulum 5 swing downward respectively. At this time, the first synchronous connecting rod 8 and the second synchronous connecting rod 7 move from the middle to both ends in the first hole 44 and the second hole 43, thereby driving the support frame 4 to sink into the storage cavity 3 for temporary storage. The upper end of the outer box 101 is sealed by the cover plate 15. Then, the inner upper frame 19 is driven to descend, so that the inner upper frame 19 presses on the outer upper frame 16 and the inner lower frame 21 presses on the outer lower frame 17.

[0049] When maintenance is required, the first swing rod 6 and the second swing rod 5 swing upwards, beyond the receiving position. At this time, the first synchronous connecting rod 8 and the second synchronous connecting rod 7 continue to move towards both ends in the first hole 44 and the second hole 43, respectively. This allows the support frame 4 to continue to move higher than the upper opening of the storage cavity 3, thus facilitating internal maintenance and cleaning.

[0050] The above-described embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Any modifications and alterations to the technical solution of the present utility model without departing from its design spirit shall fall within the protection scope defined by the claims of the present utility model.
