DETAILED DESCRIPTION
[0023] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of the present application.
[0024] When the steam sterilizer 100A is in use, some conveying equipment is usually needed to take and place the instruments (not shown in the figure) to be sterilized from the inside of the chamber 1A of the steam sterilizer 100A. Referring to Figure 1 The present application provides a feeding system of a steam sterilizer 100A for feeding the instruments to be sterilized into the chamber 1A of the steam sterilizer 100A, which comprises an inner trolley (not shown in the figure) and an outer trolley 100B, wherein the inner trolley is mainly used for carrying the instruments to be sterilized and transporting them to the inside and outside of the chamber 1A of the steam sterilizer 100A, and can enter the inside of the chamber 1A of the steam sterilizer 100A together with the instruments to be sterilized to perform the sterilization operation. The use of the inner trolley can avoid the damage or deformation of the instruments caused by the direct contact with the inside of the steam sterilizer 100A, and a plurality of instruments can be loaded in the inner trolley at a time to be transferred between the inside and outside of the steam sterilizer 100A to improve the work efficiency. In the present embodiment, the inner trolley can be mounted on the outer trolley 100B and transferred together with the outer trolley 100B.
[0025] Referring to Figure 2 The outer trolley 100B comprises a main body 1 and a frame 2, and the bottom of the main body 1 is provided with wheels 13. In the present embodiment, the main body 1 has opposite first and second ends 11 and 12, and the first end 11 is provided with a handle 111, which can be held by the staff to transfer the outer trolley 100B mounted with the inner trolley (not shown in the figure) or used alone. The frame 2 is arranged above the main body 1, and when the outer trolley 100B is mounted with the inner trolley (not shown in the figure), the lower surface of the inner trolley is movably connected with the upper surface of the frame 2. Referring to Figure 1 When the outer trolley 100B is docked with the steam sterilizer 100A, the inner trolley is configured to be moved into the inside of the chamber 1A through above the frame 2, so as to feed the instruments (not shown in the figure) to be sterilized into the chamber 1A.
[0026] In the prior art, when the outer trolley 100B is docked with the steam sterilizer 100A, the two are connected and fixed through a locking device to prevent the inner trolley and the instruments in the inner trolley from accidentally falling to the ground and causing equipment damage or personnel safety accidents when being transferred back and forth between the frame 2 of the outer trolley 100B and the chamber 1A of the steam sterilizer 100A. At present, the connection and fixation between the outer trolley 100B and the chamber 1A usually adopts manual or foot-operated docking locking, which causes the operation process to be relatively inconvenient for the worker during the locking step and affects the working efficiency of the steam sterilizer 100A to some extent.
[0027] To solve the above problems, in the present embodiment, the feeding system of the steam sterilizer 100A further comprises a first guide 3 and a docking portion 4. Specifically, referring to Figure 3 and Figure 4 The first guide 3 is arranged at the bottom of the chamber 1A of the steam sterilizer 100A and is configured as a guide slope 32 towards the outer side of the opening portion 11A of the chamber 1A. The docking portion 4 is arranged at one end of the frame 2 away from the handle 111 and comprises a rotating shaft 41 and a limiting piece 42. The rotating shaft 41 extends in the first direction from the first end 11 to the second end 12, and the limiting piece 42 is fixed at the end of the rotating shaft 41 away from the handle 111. When the outer trolley 100B is pushed towards the opening portion 11A of the chamber 1A of the steam sterilizer 100A for docking, the limiting piece 42 is in contact with the bottom 31 of the first guide and is guided by the guide slope 32 to rotate around the rotating shaft 41 to cross the top 33 of the first guide, and then moves to be limited by the inner side 34 of the first guide, thereby completing the docking. Through the above embodiment, when the worker pushes the outer trolley 100B in the feeding system of the steam sterilizer 100A to the opening portion 11A of the chamber 1A of the steam sterilizer 100A for docking, the first guide 3 can slide against the docking portion 4 and complete automatic clamping locking, so that the outer trolley 100B can be automatically locked and fixed with the chamber 1A of the steam sterilizer 100A. In this locking process, the worker does not need to operate specially, which can greatly reduce the operation difficulty of the worker in putting or taking out the instruments from the chamber 1A and improve the working efficiency of the steam sterilizer 100A to some extent.
[0028] In the present embodiment, referring to Figure 3 and Figure 4, the limiting piece 42 is a triangular plate, and the side of the triangular plate away from the handle 111 is a bevel 421. Through this embodiment, the limiting piece 42 can be closer to the first guide 3 in the direction from the first end 11 to the second end 12, that is, when the bevel 421 of the limiting piece 42 and the guide bevel 32 of the first guide 3 abut each other, the bevel 421 of the limiting piece 42 can more smoothly slide from the first guide bottom 31 to the first guide top 33. As the outer trolley 100B continues to advance towards the inside of the chamber 1A, the limiting piece 42 continues to advance towards the inside of the chamber 1A from the first guide top 33, and after the limiting piece 42 crosses the first guide top 33, the limiting piece 42 rotates in the axial direction around the pivot shaft 41 to the first guide inner side 34. At this time, the first guide 3 and the docking portion 4 are fixedly connected, that is, the outer trolley 100B and the chamber 1A of the steam sterilizer 100A are fixedly connected.
[0029] Because the volume and mass of the limiting piece 42 relative to the pivot shaft 41 are small in the embodiment, and there is friction or other resistance affecting the pivot rotation of the pivot shaft 41 between the pivot shaft 41 and the frame 2, when the limiting piece 42 crosses the first guide top 33, the weight of the limiting piece 42 itself may not be able to drive the pivot shaft 41 to pivot, causing the limiting piece 42 to fail to smoothly fall to the first guide inner side 34, that is, the limiting piece 42 and the first guide 3 fail to automatically connect, and the outer trolley 100B and the chamber 1A of the steam sterilizer 100A are still movable. Therefore, in the embodiment, the docking portion 4 further includes a tension spring 6, one end of the tension spring 6 is fixedly arranged on the frame 2, and the other end is fixedly arranged on the arc side of the pivot shaft 41. Figure 3 and Figure 5 When the limiting piece 42 has not contacted the first guide 3 or has just begun to contact the first guide bottom 31, the tension spring 6 is in a relaxed state or a state of small stretching amount, the pivot shaft 41 together with the limiting piece 42 and the tension spring 6 remains relatively fixed, the triangular face of the limiting piece 42 is in a horizontal state, and the limiting piece 42 and the tension spring 6 are on the same side of the pivot shaft 41. As the limiting piece 42 begins to contact the first guide bottom 31 and slide along the guide bevel 32 to the first guide top 33, the pivot shaft 41 begins to pivot, causing the tension spring 6 to be gradually stretched, and its elastic potential gradually increases. When the limiting piece 42 crosses the first guide top 33, the elastic potential accumulated by the tension spring 6 drives the pivot shaft 41 to reset and rotate, and drives the limiting piece 42 to rotate downward to the first guide inner side 34 to complete the connection of the limiting piece 42 and the first guide 3, that is, the docking portion 4 of the outer trolley 100B and the opening portion 11A of the chamber 1A of the steam sterilizer 100A are automatically locked and fixed.
[0030] In the process of pushing the second end 12 of the outer trolley 100B towards the opening 11A of the chamber 1A of the steam sterilizer 100A by holding the handle 111, in order to enable the limiting member 42 to abut and be clamped with the first guide 3 more conveniently and accurately, the feeding system of the present embodiment is further provided with a second guide 5, referring to Figure 3 and Figure 6 The second guide 5 is arranged at the middle part of the frame 2 close to the second end 12, and has an open part 51 with gradually shrinking opening size along with the increasing depth, which cooperates with the first guide 3 to guide and limit the relative position of the outer trolley 100B and the steam sterilizer 100A in the second direction perpendicular to the first direction. At the narrow end of the open part 51, the second guide 5 is further provided with a sliding groove 52. When the staff pushes the outer trolley 100B so that the second end 12 gradually approaches the opening 11A of the steam sterilizer 100A, and abuts the first guide 3 at any position of the inner side bevel of the open part 51. Referring to Figure 4 , then continue to push the outer trolley 100B to approach the chamber 1A, so that the guide bevel 32 of the first guide 3 moves along the inner side bevel of the open part 51 towards the sliding groove 52. Until the first guide 3 starts to enter the sliding groove 52, the triangular plate bevel 421 of the limiting member 42 starts to abut the guide bevel 32 of the first guide 3, the width of the sliding groove 52 is equal to the width of the guide bevel 32 of the first guide 3, and the length of the sliding groove 52 is not less than the distance from the bottom end of the guide bevel 32 of the first guide 3 to the inner side. When the first guide 3 completely enters the sliding groove 52 and the limiting member 42 moves to the inner side 34 of the first guide, at this time the first guide 3 is fixed in the sliding groove 52, which indicates that the outer trolley 100B and the steam sterilizer 100A are docked and automatically locked and fixed with each other.
[0031] When the limiting member 42 starts to abut the first guide 3, the first guide 3 can provide a pushing force to the limiting member 42 towards the direction opposite to the first direction; or when the limiting member 42 is clamped to the inner side 34 of the first guide, the inner side 34 of the first guide can exert a pushing force to the limiting member 42 towards the first direction. The above two pushing forces can cause the docking part 4 to move back and forth along the axial direction of the rotating shaft 41 relative to the frame 2, thereby causing the outer trolley 100B to be unable to form fixed clamping with the steam sterilizer 100A. Therefore, in the present embodiment, referring to Figure 3 and Figure 6In the position where the rotation shaft 41 is close to the first end 11 and the second end 12, a fixing ring 43 is fixedly arranged around the rotation shaft 41, and one of the planes of the fixing ring 43 abuts against the inner surface of the frame 2 at the position of the first end 11 and the second end 12, respectively. Through this embodiment, the docking portion 4 can be effectively prevented from moving forward and backward relative to the frame 2 in the axial direction of the rotation shaft 41, so that the docking and locking effect of the outer trolley 100B and the chamber 1A of the steam sterilizer 100A is more significant.
[0032] Reference Figure 3 and Figure 6 The frame 2 of the outer trolley 100B includes two second sliding rails 12A, the length direction of which is parallel to the axial direction of the rotation shaft 41, and the chamber 1A of the steam sterilizer 100A is provided with two first sliding rails 21, the length direction of which is perpendicular to the plane of the opening portion 11A of the chamber 1A. In this embodiment, the end portion of the second sliding rail 12A close to the first guide 3 is provided with a clamping table 211 at the end portion of the first sliding rail 21 close to the second end 12, respectively. When the first guide 3 is completely inserted and locked in the sliding groove 52, the end portions of the clamping tables 211 of the first sliding rail 21 and the second sliding rail 12A are clamped and abutted with each other, at this time, the first sliding rail 21 and the second sliding rail 12A remain parallel and are connected as a whole. Through the clamping of the first sliding rail 21 and the second sliding rail 12A, the fixed locking between the outer trolley 100B and the steam sterilizer 100A is more stable. After the feeding system is locked, it can ensure that the inner trolley (not shown in the figure) is transferred back and forth between the first sliding rail 21 and the second sliding rail 12A more safely, effectively reducing the risk of falling of the inner trolley and the vessels.
[0033] When the inner trolley loaded with the vessels to be sterilized is transferred from above the frame 2 of the outer trolley 100B to the designated sterilization position in the chamber 1A of the steam sterilizer 100A, or when the inner trolley is transferred from the sterilization position in the chamber 1A to the pre-set position above the frame 2 of the outer trolley 100B, it is necessary to unlock the docking position of the outer trolley 100B and the steam sterilizer 100A and transfer the outer trolley 100B to other designated positions. In this embodiment, reference Figure 3 and Figure 6, the end of the rotating shaft 41 close to the handle 111 extends below the handle 111, and the pedal 112 is connected with the rotating shaft 41 through a connecting rod. The worker can directly place the foot on the upper surface of the pedal 112, apply appropriate downward force to the pedal 112, make the pedal 112 rotate along the axial direction of the rotating shaft 41 together with the rotating shaft 41, thereby driving the limiting piece 42 to rotate along the axial direction of the rotating shaft 41 synchronously, until the projection of the limiting piece 42 along the axial direction of the rotating shaft 41 no longer coincides with the projection of the first guide 3, that is, the limiting piece 42 no longer contacts the inner side surface 34 of the first guide, at this time, it indicates that the outer trolley 100B and the steam sterilizer 100A have been unlocked. Since the tension spring 6 is synchronously stretched with the pivoting of the rotating shaft 41 at this time, it is necessary to pull the handle 111 of the outer trolley 100B while keeping the pedal 112 in the downward rotating position, so that the outer trolley 100B moves away from the opening 11A of the chamber 1A of the steam sterilizer 100A along the axial direction of the rotating shaft 41, until the limiting piece 42 moves beyond the top 33 of the first guide and moves towards the guide inclined surface 32, at this time, the unlocking between the outer trolley 100B and the steam sterilizer 100A is completed. After unlocking, the worker can release the pedal 112 and continue to pull the outer trolley 100B to other designated positions. In the above unlocking process, the worker only needs to stand at the position of the handle 111 and step on the pedal 112, so as to unlock the outer trolley 100B and the steam sterilizer 100A and move the outer trolley 100B to other designated positions through the handle 111.
[0034] The above is only a preferred embodiment of the present application, and is not used to limit the present application, any modification, equivalent replacement and improvement within the spirit and principle of the present application should be included in the protection scope of the present application.
