Background
In daily work of hospitals, a large number of medical related articles are often accompanied with the need of disinfection and sterilization, and the existing method is that medical articles needing disinfection, such as clothes used by medical workers and related medical instrument bags, are all packaged and placed on a special storage rack; then the special commodity shelf and the medical articles placed on the special commodity shelf are conveyed to a transfer trolley together; then the rack with the medical articles is integrally conveyed to a sterilization center by a transfer trolley for sterilization; the front end of the transfer cart is provided with a docking mechanism which is in docking and fixing with the sterilization center, the rear end of the transfer cart is provided with an unlocking mechanism which can release the docking state, the unlocking mechanism and the docking mechanism are linked, when in use, an operator needs to firstly place medical articles to be sterilized on a special article placing rack, then transfer the special article placing rack to a transfer trolley, then push the transfer trolley to the sterilization center and carry out docking and fixing with the sterilization center, and then push the special article placing rack into the sterilization center to finish sterilization; after the sterilization is finished, the special storage rack is pushed out and transferred to a transfer trolley; then the butt joint state of the transfer trolley and the sterilization center is released through the unlocking mechanism; and then the transfer trolley is pushed to move the special commodity shelf on the transfer trolley to a specified position, and the whole process of sterilizing the medical articles is completed.
However, the sterilization process still has many inconvenient places during the specific operation:
firstly, the method comprises the following steps: the unlocking mechanism is arranged in a structure of a hand lever, and due to the structure of the transfer trolley, an operator needs to frequently bend over when operating the unlocking mechanism on the transfer trolley, so that the labor intensity is increased, and the operation is more difficult for some operators of older ages.
II, secondly: some manufacturers improve the unlocking mechanism to be in a pedal plate form, so that the operator does not need to bend frequently, but with the structure, when the operator pushes the sterilized commodity shelf to the transfer trolley and is about to push the transfer trolley to other positions, the operator needs to complete several actions simultaneously: 1) the unlocking mechanism is stepped by feet to enable the butting mechanism at the front end to be in a butting state; 2) the handrail of the transfer trolley is held by hand, and the whole person drives the transfer trolley to move backwards so as to separate the transfer trolley from the sterilization center; when the two actions are carried out simultaneously, the feet of the operator need to move backwards while trampling the unlocking mechanism, the two actions which are quite contradictory can be imagined, the convenient degree of operation is greatly reduced, and meanwhile, the operator possibly has unstable standing condition and is easy to cause safety accidents such as side turning and the like.
Thirdly, on setting up release mechanism into the basis of pedal form, increase auto-lock part, make the foot step on behind the footboard, can make front end release mechanism keep the unblock state always, the problem that people need back again when that just can solve the foot step on the footboard, but the reduction of later auto-lock still needs manual operation, unable automatic re-setting, even want to realize automatic re-setting through some structural design, but what kind of structure can guarantee that the automatic re-setting process can not appear the jamming, sustainable effectual going on, also be a problem.
In conclusion, how to design a transfer trolley can realize effective self-locking and improve the convenient degree of operation while reducing the labor intensity and avoiding safety accidents is a problem of optimization of the transfer trolley at present.

The guide assembly 109 is a raised device secured to the head of the swing link 104b, preferably a bolt connection assembly including a connecting bolt and a connecting nut. The connecting bolt is arranged in the transition guide part 1103 in a penetrating manner, and one end of the connecting bolt is fixed on the end face of the swing connecting rod 104 b; the other end of the connecting bolt is in threaded connection with the connecting nut, so that the transition guide portion 1103 is located between the connecting nut and the swing link 104b, and finally the guide assembly 109 and the transition piece 110 form a first sliding pair connection; the first sliding pair connection enables the transition piece 110 to perform a first reciprocating linear motion along the length direction of the transition guide portion 1103.
In some embodiments, as shown in fig. 4 to 6, the apparatus further comprises a self-locking assembly 108 and a second reset member 112 fixedly connected to the second guide rail 105b, respectively. The second reset piece 112 can make the reset mechanism 104 keep fixed relative to the second guide rail 105b when no external force is applied, and make the side surface of the transition piece 110 keep close contact with the peripheral surface of the self-locking assembly 108; the self-locking assembly 108 may be located above or below the transition piece 110 in any orientation that can be attached to the transition piece 110, and to achieve this attachment, the self-locking assembly 108 may be disposed below the transition piece 110, and a plurality of springs may be disposed on the top of the second guide rail 105b to continuously apply downward pressure to the transition piece 110 to maintain the attachment; the self-locking assembly 108 may be disposed above the transition piece 110, or vice versa for the purpose of fitting.

The specific method of the second restoring member 112 enabling the restoring mechanism 104 to maintain the fixed state relative to the second guiding rail 105b when no external force is applied is as follows: when the reset mechanism 104 is not subjected to an external force, the rocker 104a located on one side of the third hinge assembly 104c tends to perform a third rotary motion clockwise under the action of gravity, and the second reset member 112 located on the other side of the third hinge assembly 104c is elastically deformed and gradually stretched to generate a first pulling force, so that when the gravity of the rocker 104a and the first pulling force are balanced, the reset mechanism 104 keeps fixed and stops the third rotary motion.
As shown in fig. 4 to 7, the second locking mechanism 103b includes a second pedal 103ba, a second pedal extension plate 103bb, and a second hinge assembly 103 bc. The head of the second pedal extension plate 103bb is provided with an extension plate connecting part 103bb1 of a flat plate structure shown in fig. 7, the extension plate connecting part 103bb1 is inserted into the transition connecting part 1101 to perform the second secondary connection, and the second secondary connection enables the second rotary motion and the first reciprocating linear motion to be linked. The top of the side surface of the extension board connecting part 103bb1 is provided with a bump structure shown in fig. 7, which can be used to prevent the extension board connecting part 103bb1 from separating from the transition connecting part 1101 during the second rotation motion, thereby preventing the second sub-connection from failing. The second hinge assembly 103bc is located at the middle of the second pedal extension plate 103bb and is fixedly connected with the second pedal connecting plate 105b 2. The second tread extension board 103bb forms a second hinge with the second tread connection board 105b2 through the second hinge assembly 103 bc. The second rotary motion is specifically: the second pedal extension plate 103bb performs a swing motion around the central axis of the second hinge assembly 103 bc. The second pedal 103ba is located at the bottom of the second pedal extension plate 103bb, and the end surface of the second pedal 103ba is fixedly connected to the side surface of the second pedal extension plate 103bb, so that the stepping area can be increased, and the stepping action is easier to realize.
As shown in fig. 3 to 5, the second secondary connection and the first fixed connection between the long link 107 and the transition piece 110 enable the first rotational motion of the front end docking mechanism 106, the first reciprocating linear motion of the transition piece 110, and the second rotational motion of the second locking mechanism 103b to perform the first linkage; thus, when the operator steps on the second pedal 103ba to input the motion, the second locking mechanism 103b is controlled to perform the second rotation motion, and then the second secondary connection drives the transition connection member 110 to perform the first reciprocating linear motion, and then the first fixed connection drives the front end docking mechanism 106 at the front end to perform the first rotation motion. Thus, the output end is represented as the open or closed state of the front end docking mechanism 106, so that the device can be docked with an external device.
