Technical Field
[0001] The utility model relates to the biochemical field, in particular to a matching cart for equipment for high-temperature sterilization of sample containers. Background Art
[0002] The container for holding the sample needs to be sterilized at high temperature. The container is hung on a bracket, and a downward convex positioning column and a positioning edge are provided at the bottom of the bracket, wherein the positioning column is located at the front end of the bracket and the positioning edge is located at the rear end of the bracket. The bracket is positioned on a cart, and the operator pushes the cart into the cavity of the high temperature sterilization equipment, and then the bracket and the container on it enter the cavity of the equipment.
[0003] Guide rails are arranged on the left and right sides of the equipment cavity, and the left and right sides of the bracket are pressed against the guide rails, that is, the bracket is in an empty state in the equipment cavity.
[0004] The patent document with authorization announcement number CN214028675U discloses a cart for high-temperature sterilization, including a frame, a front end positioning mechanism arranged on the frame, and a tail positioning mechanism arranged on the frame. The front end positioning mechanism includes a fixed positioning notch and a movably arranged first limit member, the first limit member is connected to a first operating rod, and the first operating rod extends to the tail of the frame; the tail positioning mechanism includes a fixed positioning member and a movably arranged second limit member, the second limit member is connected to a second operating rod, and the second operating rod extends to the tail of the frame.
[0005] The cart of the above patent document extends the operating rods of the two positioning mechanisms of the positioning container holder to the rear of the cart, so that the operator can easily move the holder carrying the container into and out of the cavity of the high-temperature sterilization equipment.
[0006] When releasing the bracket, the operator needs to pull the first operating lever, the first limiter is rotated, and the locking of the positioning column is released; the operator presses down the second operating lever, the second limiter is pressed down, and the locking of the positioning edge is released. In addition, the operator needs to hold the rack. In the three actions, the locking of the positioning edge and the locking of the positioning column need to be maintained, and then the operator can pull back the cart and pull the rack out of the equipment cavity.
[0007] After high-temperature sterilization is completed, the operator opens the door of the equipment and pushes the cart into the cavity of the equipment. The first limiter and the second limiter are activated, and the first limiter opens the positioning notch. The positioning column fits in it and is limited by the first limiter; the positioning edge is positioned by the positioning component and the second limiter. After that, the operator pulls back the cart, and the cart takes the bracket and the container on it out of the equipment cavity. In order to remove the bracket from the cart, the operator needs to unlock the positioning edge and unlock the positioning column. These two unlocking states need to be maintained before the operator can remove the bracket from the cart. In this way, whether it is to send the bracket into the cavity or to remove the bracket after it is out of the cavity, the operation is inconvenient. Utility Model Content
[0008] The technical problem solved by the utility model is: how to make it convenient to separate the bracket from the cart.
[0009] To solve the above technical problems, the utility model provides the following technical solutions: a trolley for entering and exiting sterilization equipment, comprising a frame, a front end positioning mechanism arranged on the frame, and a tail positioning mechanism arranged on the frame, the front end positioning mechanism comprising a fixed positioning notch and a movably arranged first limit piece, the first limit piece is connected to a first operating rod, and the first operating rod extends to the tail of the frame; the tail positioning mechanism comprises a fixed positioning piece and a movably arranged second limit piece, the second limit piece is connected to a second operating rod, and the second operating rod extends to the tail of the frame; the tail of the frame is hinged with a rotating assembly, the rotating assembly comprises a rotating shaft pivotally connected to the frame, a rotating frame connected to the rotating shaft and a pressure block, the rotating frame is connected with a steel wire, the steel wire is connected to the first operating rod, and the pressure block can press down the second operating rod.
[0010] The bracket carrying the container is placed on the rack, the bracket's positioning column is positioned by the front positioning mechanism, and the bracket's positioning edge is positioned by the rear positioning mechanism. The operator pushes the rack into the high-temperature sterilization equipment cavity, and the left and right edges of the bracket are pressed against the left and right guide rails of the equipment cavity. Afterwards, the operator operates the rotating assembly at the rear of the cart, that is, at the rear of the cart, and the rotating frame rotates 90 degrees backward around the rotating axis. The rotating frame pulls the steel wire backward, and the steel wire pulls the first operating rod backward. The pressure block rotates with the rotating axis, presses on the second operating rod, and presses down the second operating rod. In this way, the first limit member releases the positioning column, and the second limit member releases the positioning edge.
[0011] Afterwards, the operator pulls the cart back to pull the rack out of the equipment cavity, leaving the rack in the equipment cavity. Afterwards, the door of the high-temperature sterilization equipment is closed, and the equipment performs high-temperature sterilization on the container on the rack. The operator rotates the rotating assembly forward to reset it.
[0012] After the high-temperature sterilization is completed, the operator opens the door of the device and pushes the cart into the cavity of the device. The first stopper and the second stopper are activated, the first stopper opens the positioning notch, the positioning column fits in it and is limited by the first stopper; the positioning edge is positioned by the positioning member and the second stopper. Afterwards, the operator pulls the cart back, and the cart takes the bracket and the container on it out of the cavity of the device.
[0013] When the bracket needs to be removed from the cart, the operator rotates the rotating assembly, the rotating frame rotates 90 degrees backward around the rotating axis, the rotating frame pulls the steel wire backward, and the steel wire pulls the first operating rod backward. The pressing block rotates with the rotating axis, presses on the second operating rod, and presses down the second operating rod. In this way, the first limiting member releases the positioning column, the second limiting member releases the positioning edge, the bracket is released, and the operator can remove the bracket from the cart.
[0014] The utility model extends the operating rods of the two positioning mechanisms of the container bracket to the rear of the cart, which is convenient for the operator to put the bracket carrying the container in and out of the cavity of the high-temperature sterilization equipment. The rotating assembly of the utility model can drive the operating rods of the two positioning mechanisms at the same time, which is convenient for operation.
[0015] The frame is provided with a limit shaft, and a limit hook is installed on the rotating shaft, and the limit hook can be engaged with the limit shaft. After the rotating frame rotates backward 90 degrees around the rotating shaft, the limit hook rotating with the rotating shaft is engaged with the limit shaft to limit the rotation of the rotating assembly. When the rotating assembly needs to be rotated and reset, the operator pushes the rotating assembly forward with force to disengage the limit hook from the limit shaft.
[0016] A positioning notch is provided on a plate, a first limiting member is hinged on the plate, the first limiting member is L-shaped, a first side of the first limiting member is hook-shaped, and a second side of the first limiting member is hinged to a first operating rod; the first side of the first limiting member can be closed on the positioning notch, an arc groove is provided on the plate, and a hinge axis between the first operating rod and the first limiting member can slide in the arc groove.
[0017] Driven by the rotating assembly, the steel wire pulls the first operating rod backward, and the first operating rod pulls the first limiting piece to rotate, and the first hook-shaped edge leaves the positioning notch, that is, the first edge opens the positioning notch, and the positioning column of the bracket carrying the container can enter the positioning notch. After the positioning column enters the positioning notch, the first operating rod resets forward and drives the first limiting piece to rotate, and the first hook-shaped edge seals the positioning notch, so that the positioning column is confined in the positioning notch.
[0018] The first operating rod is sleeved with a first return spring, which is located at the tail of the frame. The first return spring is located in a cylindrical member, and the steel wire extends into the cylindrical member and is connected to the tail end of the first operating rod. One end of the cylindrical member is screwed with a threaded member, which is hollow, and the steel wire passes through the threaded member, and the threaded member limits the first return spring in the cylindrical member. The first return spring has a tendency to rotate the first edge of the first limit member toward the positioning notch. When the first operating rod is not affected by external force, due to the existence of the first return spring, the hook-shaped first edge keeps the state of blocking the positioning notch.
[0019] As an improvement, a conical guide opening is provided in front of the positioning notch, and the front end of the first side is pointed. When the first operating rod is not subjected to external force, the hook-shaped first side remains in a state of blocking the positioning notch, and at this time, the first side and one side of the guide opening form a V-shaped opening. The operator pushes the cart into the equipment cavity, and the V-shaped opening moves toward the positioning column of the bracket. Since the front end of the bracket presses against the side wall of the equipment cavity, the advancing V-shaped opening can make the positioning column snap into the V-shaped opening, and the positioning column pushes the first side away and then enters the positioning notch. Under the action of the first reset spring, the first side is reset again, and the positioning column entering the positioning notch is sealed.
[0020] The plate can not only locate the positioning column of the bracket, but also play the role of connecting the left and right side beams of the frame. The frame also includes a support structure, the support structure supports the left and right side beams, the support structure is provided with a push-pull handle, the push-pull handle is provided with a support, the rotating shaft is pivoted on the support, and the limit shaft is installed on the push-pull handle. The push-pull handle can be welded or fixed to the support structure by a screw connector.
[0021] The second limit piece is hinged on the frame, and the second limit piece is connected to the second return spring. Under the action of the second return spring, the second limit piece protrudes upward from the frame and forms a positioning bayonet with the positioning piece. The operator pushes the cart into the equipment cavity, and the positioning column of the bracket is limited or positioned by the front positioning mechanism. At the same time, the positioning edge of the bracket acts on the second limit piece, and the second limit piece passively rotates downward. After the positioning edge passes over the second limit piece, under the action of the second return spring, the second limit piece protrudes upward from the frame again to limit the positioning edge. As an improvement, an amplitude limiting piece is installed on the frame, and a strip groove is formed between the amplitude limiting piece and the side beam of the frame. The second operating rod is inserted into the strip groove, and the amplitude of the second operating rod swinging up and down is limited by the amplitude limiting piece.
[0022] The operator pulls the cart out of the equipment cavity and takes out the bracket with the container. Then, the operator rotates the rotating assembly, and the rotating frame rotates 90 degrees backward around the rotating axis. The rotating frame pulls the steel wire backward, and the steel wire pulls the first operating rod backward to release the lock on the positioning column. The pressing block rotates with the rotating axis, pressing down the second operating rod to release the lock on the positioning edge. In this way, the operator can take the bracket from the cart.

The front-end positioning mechanism comprises a fixed positioning notch 21 and a movable first stopper 22, the first stopper is connected to a first operating rod 23, and the first operating rod extends to the rear of the frame; the rear-end positioning mechanism comprises a fixed positioning member 31 and a movable second stopper 32, the second stopper is connected to a second operating rod 33, and the second operating rod extends to the rear of the frame. A rotating assembly 50 is hinged at the rear of the frame, and the rotating assembly comprises a rotating shaft 51 pivotally connected to the frame, a rotating frame 52 connected to the rotating shaft, and a pressing block 53, the rotating frame is connected to a steel wire 54, the steel wire is connected to the first operating rod, and the pressing block can press down the second operating rod. Rollers are provided at the bottom of the trolley.
[0038] Combination Figures 1 to 4 The positioning notch 21 is provided on a plate 24, the first stopper 22 is hinged on the plate, the first stopper is L-shaped, the first side 221 of the first stopper is hook-shaped, and the second side 223 of the first stopper is hinged to the first operating rod 23; the first side of the first stopper can be closed on the positioning notch, the plate is provided with an arc groove 240, and the hinge shaft 25 of the first operating rod and the first stopper can slide in the arc groove. Afterwards, the operator operates the rotating assembly 50 at the rear of the cart, that is, at the tail of the cart, and the rotating frame 52 rotates backward 90 degrees around the rotating shaft 51, and the rotating frame pulls the steel wire 54 backward, and the steel wire pulls the first operating rod 23 backward. The first operating rod pulls the first limiting member to rotate, and the hook-shaped first edge 221 leaves the positioning notch 21, that is, the first edge opens the positioning notch, and the positioning column of the bracket carrying the container can enter the positioning notch. After the positioning column enters the positioning notch, the first operating rod resets forward and drives the first limiting member to rotate, and the hook-shaped first edge seals the positioning notch, so that the positioning column is confined in the positioning notch.
[0039] The first operating rod 23 is sleeved with a first return spring 26, which is located at the rear of the frame 10. The first operating rod 23 is sleeved with a first return spring 26, which is located in a tubular member, and a steel wire extends into the tubular member and is connected to the rear end of the first operating rod. The first return spring has a tendency to rotate the first edge of the first limiter toward the positioning notch. When the first operating rod is not subjected to external force, due to the presence of the first return spring, the hook-shaped first edge maintains a state of blocking the positioning notch.
[0040] The frame 10 is provided with a limit shaft 55, and the rotating shaft 51 is provided with a limit hook 56, which can be engaged with the limit shaft. After the rotating frame 52 rotates backward 90 degrees around the rotating shaft 51, the limit hook 56 rotating with the rotating shaft 51 is engaged with the limit shaft 55 to limit the rotation of the rotating assembly 50. When the rotating assembly 50 needs to be rotated and reset, the operator pushes the rotating assembly 50 forward with force to disengage the limit hook 56 from the limit shaft 55.
[0041] As an improvement, a conical guide opening 210 is provided in front of the positioning notch 21, and the front end of the first edge 221 is pointed. When the first operating rod is not subjected to external force, the hook-shaped first edge keeps blocking the positioning notch, and at this time, the first edge 221 and one side of the guide opening 210 form a V-shaped opening. The operator pushes the cart into the equipment cavity, and the V-shaped opening moves toward the positioning column 41 of the bracket. Since the front end of the bracket presses against the side wall of the equipment cavity, the advancing V-shaped opening can make the positioning column snap into the V-shaped opening, and the positioning column pushes the first edge 221 away and enters the positioning notch 21. Under the action of the first reset spring 26, the first edge 221 is reset again, and the positioning column 41 entering the positioning notch is sealed.

[0043] Combination Figure 2 , Figure 7The second limiter 32 is hinged on the frame 10, and the second limiter is connected to the second return spring 34. Under the action of the second return spring, the second limiter protrudes upward from the frame and forms a positioning bayonet with the positioning member 31. The operator pushes the cart into the equipment cavity, and the positioning column 41 of the bracket is limited or positioned by the front positioning mechanism 20. At the same time, the positioning edge 42 of the bracket acts on the second limiter 32, and the second limiter passively rotates downward. After the positioning edge passes over the second limiter, under the action of the second return spring 34, the second limiter protrudes upward from the frame again to limit the positioning edge. As an improvement, an amplitude limiting member 35 is installed on the frame 10, and a strip groove is formed between the amplitude limiting member and the side beam 11 of the frame. The second operating rod 33 is inserted into the strip groove, and the amplitude of the second operating rod swinging up and down is limited by the amplitude limiting member.
[0044] The operator pulls the cart out of the equipment cavity and takes out the bracket with the container. Then, the operator rotates the rotating assembly 50, and the rotating frame 52 rotates 90 degrees around the rotating shaft 51. The rotating frame 52 pulls the steel wire 54 backward, and the steel wire pulls the first operating rod 23 backward, and the first stopper 22 is rotated to release the lock on the positioning column 41; the pressing block 53 rotates with the rotating shaft 51, pressing down the second operating rod 33, and the second stopper 32 is pressed down to release the lock on the positioning edge 42.
