Description

Technical Field

[0001] The utility model relates to a specimen clamp, in particular to an opening and closing rotating clamp for transporting human specimens. Background Art

[0002] Human specimens are specimens made after the human body has undergone a series of chemical treatments. They are used for anatomical research and study, to promote the understanding of human structure and function, and to promote the development of medical research.

[0003] At present, human specimens are preserved in a pool with formalin. When a human specimen is needed, it needs to be manually tied up and lifted up to move it to a transport carrier, and then moved to the dissection table. The tied human specimen has a hanging rod for easy clamping. The process of tying human specimens is relatively cumbersome. Each human specimen is very valuable, so it is necessary to ensure that the binding is firm, which further affects the moving efficiency. The clamps used for lifting are often clamped by clamp cylinders due to environmental restrictions. Human specimens have a certain weight, and the weight that the clamp cylinder can clamp is limited. There is a risk of slipping, the clamping stability is poor, and the clamping cylinder and the hanging rod need to be accurately matched to clamp accurately, resulting in low clamping efficiency.

[0014] After adopting the above technical scheme, the effect of the utility model is as follows: since the opening and closing rotating clamp for transporting human specimens includes a connecting plate, a left claw cover shell and a right claw cover shell are fixedly installed at both ends of the connecting plate, the left claw cover shell and the right claw cover shell have the same structure, the left claw cover shell includes an outer mounting plate and an inner fixing plate, the outer mounting plate and the inner fixing plate are provided with a downward clamping opening, and a driven rotating gear ring and an active driving gear that cooperate with each other are rotatably installed between the outer mounting plate and the inner fixing plate, the driven rotating gear ring is provided with a gear opening corresponding to the clamping opening, the active driving gear is driven to rotate by a driving power device, and when the gear opening coincides with the clamping opening, the driven rotating gear ring is located at the opening position, and when the gear opening seals the clamping opening, the driven rotating gear ring is located at the locking position, and the inner fixing plate The fixed plate is provided with a limit device which limits the active driving gear to drive the driven rotating gear ring to reciprocate between the opening position and the locking position; by driving the active driving gear to rotate by the driving power device, the driven rotating gear ring can be driven to rotate, so that the driven rotating gear ring rotates to the opening position, the clamping opening and the gear opening coincide, and the suspension rod is effectively clamped, and then the driven rotating gear ring is continued to be driven to rotate, so that the driven rotating gear ring rotates to the locking position, so that the suspension rod can be in the clamping opening and is sealed by the gear opening, when the active driving gear does not rotate, the driven rotating gear ring cannot rotate either, forming a self-locking, thus improving the clamping stability effect and having a stronger bearing capacity, and the limit device prevents the active gear from rotating excessively, resulting in the driven rotating gear ring being unable to accurately rotate to the opening position or the locking position, thereby ensuring that the clamping suspension rod is stable and reliable and the clamping is simple and convenient.

[0015] Furthermore, since the outer mounting plate and the inner fixed plate are provided with accommodating grooves for accommodating the driven rotating gear ring and the active driving gear, the active driving gear is rotatably installed in the accommodating groove, annular protrusions are provided on both sides of the driven rotating gear ring, annular grooves corresponding to the annular protrusions are provided in the accommodating groove, the annular protrusions are constrained in the annular grooves, and a detection switch device for detecting the suspension rod to control the driven rotating gear ring is provided on the inner fixed plate, and a sensing device for sensing the lifting position of the lifting shaft is also provided on the connecting plate; the outer mounting plate and the inner fixed plate can effectively protect the active driving gear and the driven rotating gear ring in the accommodating groove, and after the annular protrusion on the driven rotating gear ring is stuck in the annular groove, it is ensured that the driven rotating gear ring can also effectively rotate and will not move, and the rotation is stable and the clamping is firm.

[0016] Furthermore, since the limit device includes two proximity switches, the proximity switches are fixedly mounted on the inner fixed plate and located in the accommodating groove, a touch table is mounted on the active driving gear and rotates synchronously with the active driving gear to touch the proximity switch, and the touch table touches the proximity switch corresponding to the driven rotating gear ring being in the opening position or the locking position respectively; in this way, when the active driving gear rotates, it drives the driven rotating gear ring to rotate, and the touch table moves away from the proximity switch corresponding to the opening position, and then until the touch table touches the locking position, the gear opening will clamp the opening and seal it, the active driving gear will no longer rotate, and the driven rotating gear ring will not rotate either, and vice versa, ensuring that the driven rotating gear ring will not rotate excessively, thereby improving efficiency.

[0017] In addition, a limit rod is provided between the proximity switches to cooperate with the touch table to prevent the active driving gear from rotating excessively; the proximity switch is prevented from being invalid, the active gear still rotates, causing the driven rotating gear ring to rotate and unable to effectively clamp, thereby improving safety and accuracy in use.

[0018] Furthermore, since the detection switch device includes a rotary travel switch fixed on an inner fixed plate, a detection rod is installed on the rotating head of the rotary travel switch, and an adjustment structure for adjusting the length of the detection rod is provided on the rotating head, and the detection rod is located above the hanging rod; in order to accurately clamp, it is necessary to detect the position of the hanging rod, and when the clamp descends, the rotating head rotates to deflect the detection rod, so that the detection rod can be placed on the hanging rod. When it continues to descend, the detection rod will continue to deflect. When the detection rod is deflected to a certain angle, the hanging rod is located in the gear opening and the clamping opening, so that the driven rotating gear ring will rotate to seal the clamping opening, thereby completing the clamping of the detection rod.

[0019] Since the connecting plate is provided with an interface connected to the lifting shaft, the connecting plate is also provided with a sensing device for sensing the lifting position of the lifting shaft, the sensing device includes an end face sensing head fixed on the connecting plate and a side sensing head fixed on one side of the connecting plate, a fixed bracket is provided on one side of the connecting plate, and the side sensing head is lifted and installed on the fixed bracket; in this way, the lifting height of the clamp can be detected and sensed to avoid over-lifting and affecting the use effect.

[0020] Since two strip holes are vertically arranged on the fixing bracket, the side sensing head is fixed on the adjustment bracket, and the adjustment bracket is installed on the fixing bracket by adjusting the lifting height of the screws; thus, the installation height of the side sensing head can be changed, thereby improving flexibility.

[0021] Since a circular through hole corresponding to the active driving gear is provided on the outer side of the outer mounting plate, a cover plate covering the circular through hole is detachably mounted on the outer mounting plate; the circular through hole facilitates direct observation of the interior, facilitates maintenance, and improves convenience.

[0022] Furthermore, since guiding slopes are arranged at the edges of the clamping openings of the outer mounting plate and the inner fixing plate, the clamping openings can be guided when clamping into the hanging rod, thereby ensuring accurate clamping. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] The present invention is further described in detail below through specific embodiments.

[0031] like Figures 1 to 5As shown, an opening and closing rotating clamp for transporting human specimens comprises a connecting plate 1, a left claw cover 2 and a right claw cover 3 are fixedly installed at both ends of the connecting plate 1, the left claw cover 2 and the right claw cover 3 have the same structure, the left claw cover 2 comprises an outer mounting plate 4 and an inner fixing plate 5, the outer mounting plate 4 and the inner fixing plate 5 are provided with a downward clamping opening 6, a driven rotating gear ring 7 and an active driving gear 8 which cooperate with each other are rotatably installed between the outer mounting plate 4 and the inner fixing plate 5, the driven rotating gear ring 7 is provided with a gear opening 9 corresponding to the clamping opening 6, the active driving gear 8 is driven to rotate by a driving power device, when the gear opening 9 coincides with the clamping opening 6, the driven rotating gear ring 7 is located at an opening position 31, when the gear opening 9 seals the clamping opening 6, the driven rotating gear ring 7 is located at a locking position, and a limiting device is provided on the inner fixing plate 5 for limiting the active driving gear 8 from driving the driven rotating gear ring 7 to reciprocate between the opening position 31 and the locking position.

[0032] In this embodiment, the inner fixing plate 5 is fixedly installed at both ends of the connecting plate 1 by screw connection, and the outer mounting plate 4 is fixedly installed on the inner fixing plate 5 by screw connection. The middle parts of the clamping opening 6 and the gear opening 9 are both circular, which can be adapted to the suspension rod, and the clamping opening 6 and the gear opening 9 are coaxially installed to ensure stable clamping; the driving power device includes a driving motor 10, which is fixedly installed on the inner fixing plate 5, and the output shaft passes through the inner fixing plate 5 to drive the active driving gear 8 to rotate; a reinforcement rod 32 is also fixedly installed between the left claw cover 2 and the right claw cover 3, and both ends of the reinforcement rod 32 are fixedly installed on the inner fixing plate 5 by screws.

[0033] like Figure 3 and Figure 5 As shown, the outer mounting plate 4 and the inner fixing plate 5 are provided with a receiving groove 11 for accommodating the driven rotating ring gear 7 and the active driving gear 8, and the active driving gear 8 is rotatably mounted in the receiving groove 11. Annular protrusions 12 are provided on both sides of the driven rotating ring gear 7, and an annular groove 13 corresponding to the annular protrusion 12 is provided in the receiving groove 11. The annular protrusion 12 is constrained in the annular groove 13. A detection switch device for detecting the control of the driven rotating ring gear 7 by the hanging rod is provided on the inner fixing plate 5, and a sensing device for sensing the lifting position of the lifting shaft is also provided on the connecting plate 1; the annular protrusion 12 is installed on the driven rotating ring gear 7, and due to the gear opening 9, the annular protrusion 12 is also provided with a corresponding opening, and the annular groove 13 is similarly provided with a corresponding opening, and the opening size is the same, and the distance between the openings is smaller than the circular diameter of the middle part, ensuring that the driven rotating ring gear 7 can stably rotate in the annular groove 13, and the outer mounting plate 4 and the inner fixing plate 5 can effectively protect the active driving gear 8 and the driven rotating ring gear 7 in the receiving groove 11.

[0034] like Figure 2and Figure 3 As shown, the limit device includes two proximity switches 14, which are fixedly mounted on the inner fixed plate 5 and located in the accommodating groove 11. A touch table 81 is installed on the active driving gear 8, which rotates synchronously with the active driving gear 8 to touch the proximity switch 14. The touch table 81 touches the proximity switch 14 and corresponds to the driven rotating gear ring 7 being in the opening position 31 or the locking position respectively; in this way, when the active driving gear 8 rotates, it drives the driven rotating gear ring 7 to rotate, and the touch table 81 moves away from the proximity switch 14 corresponding to the opening position 31, and then until the touch table 81 touches the locking position, the gear opening 9 will seal the clamping opening 6, the active driving gear 8 will no longer rotate, and the driven rotating gear ring 7 will not rotate either. Conversely, it is ensured that the driven rotating gear ring 7 will not rotate excessively, thereby improving efficiency.

[0035] Furthermore, a limit rod 15 is provided between the proximity switches 14 to cooperate with the touch platform 81 to prevent the active driving gear 8 from rotating excessively. The limit rod 15 is fixed to the inner fixing plate 5 by screws. When the touch platform 81 touches the limit rod 15, it cannot rotate, thereby preventing the proximity switch 14 from being invalid, the active gear still rotating, causing the driven rotating gear ring 7 to rotate, and being unable to be effectively clamped, thereby improving safety and accuracy in use.

[0036] like Figure 4 As shown, the detection switch device includes a rotary travel switch 16 fixed on the inner fixed plate 5, and a detection rod 18 is installed on the rotating head 17 of the rotary travel switch 16. The rotating head 17 is provided with an adjustment structure for adjusting the length of the detection rod 18, and the detection rod 18 is located above the hanging rod; in order to clamp accurately, it is necessary to detect the position of the hanging rod. When the clamp descends, the rotating head 17 rotates to deflect the detection rod 18, so that the detection rod 18 can be placed on the hanging rod when descending due to its inclination. When continuing to descend, the detection rod 18 will continue to deflect. When the detection rod 18 deflects to a certain angle, the hanging rod is in the gear. The driven rotating gear ring 7 is rotated to seal the clamping opening 6 and complete the clamping of the detection rod 18. The rotary travel switch 16 can effectively transmit a signal to the drive motor 10 to drive the active drive gear 8. The adjustment structure includes a mounting seat 19 fixedly mounted on the rotating head 17, and the mounting seat 19 is provided with a notch 20 that cooperates with the suspension rod, and the mounting seat 19 is screwed with a pressure plate 21 covering the clamping notch 20. In this way, by tightening the screws, the pressure plate 21 can be pressed on the suspension rod to fix the suspension rod. Conversely, by loosening the screws, it can be adjusted along the notch 20, which is simple and convenient.

[0037] like Figure 1As shown, the connecting plate 1 is provided with an interface 22 connected to the lifting shaft, and the connecting plate 1 is also provided with a sensing device for sensing the lifting position of the lifting shaft, the sensing device includes an end face sensing head 23 fixed on the connecting plate 1 and a side sensing head 24 fixed on one side of the connecting plate 1, a fixed bracket is provided on one side of the connecting plate 1, and the side sensing head 24 is installed on the fixed bracket for lifting; in this way, the lifting height of the clamp can be detected and sensed to avoid over-lifting and affecting the use effect.

[0038] Furthermore, two strip holes 25 are vertically provided on the fixed bracket, and the side sensing head 24 is fixed on the adjustment frame 28, and the adjustment frame 28 is installed on the fixed bracket by screw lifting and lowering adjustment; in this way, the installation height of the side sensing head 24 can be changed, thereby changing the overall lifting height of the clamp and improving flexibility.

[0039] In this embodiment, a circular through hole 26 corresponding to the active driving gear 8 is provided on the outer side of the outer mounting plate 4, and a cover plate 27 covering the circular through hole 26 is detachably installed on the outer mounting plate 4; the circular through hole 26 is convenient for direct observation of the interior, convenient for maintenance, and improved convenience.

[0040] Furthermore, guide slopes 29 are provided at the edges of the clamping openings 6 of the outer mounting plate 4 and the inner fixing plate 5, which can provide guidance when the clamping openings 6 are clamped into the hanging rod, thereby ensuring accurate clamping.

[0041] The working principle of this embodiment is as follows: first, the driven rotating ring gear 7 is in the opening station 31, and the detection rod 18 is tilted and swung to a certain angle. When the clamp descends, the detection rod 18 can touch the suspension rod, and then continues to descend. When the detection rod 18 is tilted and swung to a fixed angle, the corresponding suspension rod enters the clamping opening 6, and then the driving motor 10 drives the active driving gear 8 to rotate and drive the driven rotating ring gear 7 to rotate, and rotate from the opening station 31 to the clamping station 30, so that the clamping opening 6 can be sealed and the clamping of the suspension rod is completed. When clamped to the required position, the driven rotating ring gear 7 rotates to the opening station 31 again, the suspension rod falls, and the detection rod 18 automatically resets to the initial state.

[0042] The above-described embodiments are merely descriptions of preferred implementations of the present invention and are not intended to limit the scope of the present invention. Various modifications and alterations to the technical solution of the present invention, without departing from the design spirit of the present invention, should fall within the scope of protection defined in the claims of the present invention.
