Abstract
Description
Technical Field
[0001] This application relates to the field of drawer switch technology, and more particularly to a locking mechanism and a medical device. Background Technology
[0002] Medical care equipment is equipped with trolleys, which have drawers for storing medical supplies for easy access by staff. The drawers are typically pull-out type, requiring manual pulling and pushing. When medical care is being performed and the supplies are no longer needed, the drawer is simply pushed back into the trolley; there is no locking mechanism, only slight restraint due to friction. However, in practice, as staff move around, accidental bumping of the trolley can cause it to move significantly, potentially throwing the drawers out and hindering staff movement, making medical care difficult. It could also cause medical supplies to fall to the floor, increasing cleanup work. Utility Model Content
[0003] This application provides a locking mechanism and a medical device. The locking mechanism can be connected to a trolley drawer of the medical device, so that the trolley drawer can be closed by pushing and locking the drawer inside the trolley, which is convenient for staff to move around. To open the trolley drawer, the staff only needs to push the opening part to unlock the drawer, and then pull it to open the trolley drawer.
[0004] This application provides a locking mechanism in a first aspect, including a base, an abutment member, a first elastic member, a closing member, and an opening member;
[0005] The base defines an installation area;
[0006] The abutment is disposed within the installation area;
[0007] The first elastic element is connected to both the abutting element and the seat body;
[0008] The first end of the closing member is connected to the installation area, and the first end of the closing member has a locking step. The second end of the closing member is configured to connect with an external moving part.
[0009] The first end of the opening member is connected to the installation area and is in movable contact with the abutment portion, while the second end of the opening member is located outside the installation area.
[0010] The closing member can be driven to move along a first preset path and push open the abutment member, causing the abutment member to move along a second preset path. As the closing member continues to move, the end of the abutment member passes over the end of the closing member and rebounds, abutting against the locking step to lock the closing member in the first position.
[0011] The opening member can be driven to move on a third preset path and push open the abutment member, causing the abutment member to move on the second preset path and leave the locking step, thereby releasing the closing member, which can be driven back to the second position.
[0012] In some embodiments, the locking mechanism includes at least two abutments, which are arranged in a circular pattern around the end of the first end of the closing member, and each abutment is movably connected to the seat via a first elastic member.
[0013] In some embodiments, the end of the abutting member is formed with a first abutting portion and a second abutting portion;
[0014] The first end of the closing member has a closing mating part, and the closing mating part and the first abutting part form a movable contact to push the abutting member open;
[0015] The first end of the opening member has an opening engagement portion, which makes active contact with the second abutment portion, thereby opening the abutment member.
[0016] In some embodiments, the first abutting portion is hook-shaped, a first abutting surface is formed on the side of the first abutting portion facing the closing member, and a locking surface is formed on the side away from the closing member. The first abutting surface can make movable contact with the surface of the closing mating portion. The locking surface is perpendicular to the first preset path, and when the closing member is in the first position, the locking surface and the surface of the locking step make abutting contact.
[0017] The second abutting part has a second abutting surface on the side facing the opening member, and the second abutting surface can make active contact with the opening mating part.
[0018] In some embodiments, the first preset path and the third preset path are parallel, and the second preset path and the first preset path are perpendicular;
[0019] The closing member can be driven to move on the first preset path, and the closing engagement part on it can push open the first abutting part, so that the abutting member moves on the second preset path. Under the drive of the first elastic member, the first abutting part passes over the closing engagement part and rebounds, abutting against the locking step, locking the closing member in the first position.
[0020] The opening member can be driven to move along the third preset path, and the opening engagement part thereon can push open the second abutment part, so that the abutment member moves along the second preset path. The first abutment part leaves the locking step, releasing the closing member, so that the closing member can be driven to move to the second position.
[0021] In some embodiments, the closing element can be driven to slide or rotate in a straight line;
[0022] And / or, the opening element can be driven to slide linearly or rotate.
[0023] In some embodiments, the locking mechanism further includes a second elastic element and a third elastic element;
[0024] The second elastic element connects the closing element and the seat respectively, and the second elastic element has the tendency to push the closing element to move along the first preset path and away from the seat;
[0025] The third elastic element is connected to the opening element and the seat respectively, and the third elastic element has the tendency to push the opening element to move along the third preset path and leave the seat.
[0026] In some embodiments, the locking mechanism further includes a pusher member disposed on the first preset path, and the second elastic member is connected to the pusher member and the base body respectively;
[0027] When the opening member is driven to push open the abutment member, causing the abutment member to leave the locking step, the pushing member, driven by the second elastic member, pushes the closing member back to the second position.
[0028] In some embodiments, the end of the abutment member is formed with a first abutment portion and a clearance step, and the first abutment portion and the first end of the closing member form a movable contact;
[0029] The pusher has a pusher boss, and when the closing member is in the second position, the pusher boss abuts against the clearance step.
[0030] The present application also provides a medical device in a second aspect, including a locking mechanism as described in the first aspect and a movable worktable;
[0031] The mobile workbench is equipped with drawers;
[0032] The locking mechanism is disposed on the movable worktable, and the second end of the closing member is connected to the drawer.
[0033] As can be seen from the above technical solutions, the embodiments of this application have the following advantages:
[0034] The second end of the closing part of the locking mechanism can be connected to a drawer of a trolley, such as a medical device. The operator can manually push the drawer or the second end of the closing part to move the closing part along a first preset path and push open the abutment inside the seat, forcing the abutment to move along a second preset path. As the closing part continues to move, the end of the abutment can spring back past the end of the closing part and abut against the locking step, locking the closing part in the first position. At this time, the drawer is inside the trolley and locked by the locking mechanism. Even if the operator accidentally touches the trolley, the drawer will not be thrown out. When the operator wants to open the drawer, they can drive the opening part to move along a third preset path and push open the abutment, forcing the abutment to move along the second preset path and leave the locking step to release the closing part. The drawer is then unlocked. At this time, the operator can manually pull the closing part back to the second position and pull the drawer out of the trolley.
[0035] The medical device of this application uses the aforementioned locking mechanism, which allows the drawer to be closed with a push and opened with a single button, making it convenient for staff to operate. It can also lock the drawer inside the mobile workbench to facilitate staff movement. Attached Figure Description

[0049] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0050] like Figures 1-10As shown, in a first aspect, this application provides a locking mechanism including a base 1, an abutment 2, a first elastic member 3, a closing member 4, and an opening member 5; the base 1 defines an installation area 11, the abutment 2 is disposed within the installation area 11, the first elastic member 3 is connected to the abutment 2 and the base 1 respectively, the first end of the closing member 4 is connected to the installation area 11, the first end of the closing member 4 forms a locking step 41, the second end of the closing member 4 is configured to connect to an external moving member (which may be a trolley drawer 9 of a medical device), the first end of the opening member 5 is connected to the installation area 11 and is in active contact with the abutment, and the second end of the opening member 5 is located outside the installation area 11.
[0051] The second end of the closing part 4 of the locking mechanism can be connected to the drawer 9 of a trolley, such as a medical device. The operator can manually push the drawer 9 or the second end of the closing part 4 to make the closing part 4 move on the first preset path L1 and push open the abutment 2, forcing the abutment 2 to move on the second preset path L2. As the operator continues to apply force, the closing part 4 is driven to move continuously, causing the end of the abutment 2 to pass over the end of the closing part 4 and rebound, and abut against the locking step 41, locking the closing part 4 in the first position. At this time, the drawer 9 is located inside the trolley and is locked. Even if the operator accidentally touches the trolley, the drawer 9 will not be thrown out. If the operator wants to open the drawer 9 and take out the medical supplies inside, the operator can manually drive the opening part 5 to move on the third preset path L3 and push open the abutment 2, causing the abutment 2 to move on the second preset path L2 and leave the locking step 41 to release the closing part 4. The drawer 9 is unlocked. At this time, the operator can manually pull the closing part 4 back to the second position and pull the drawer 9 out of the trolley.
[0052] Please see Figure 3 and Figure 5 In this application, the terms "first position" and "second position" for the closing member 4 are relative to the abutment member 2. When the closing member 4 is in the first position, the drawer 9 is located inside the trolley, and the end of the abutment member 2 abuts against the locking step 41 at the first end of the closing member 4, thereby restricting the closing member 4 on the first preset path L1. The closing member 4 cannot be pulled back, that is, the drawer 9 is locked and cannot be pulled out. Afterward, the opening member 5 can be driven to move, pushing the abutment member 2 open and unlocking the closing member 4. Then, the closing member 4 and the drawer 9 are pulled out as a whole, and the drawer 9 is pulled out of the trolley. At this time, the closing member 4 is in the second position.
[0053] Whether the closing part 4 moves to push open the abutting part 2, or the opening part 5 moves to push open the abutting part 2, the abutting part 2 can be reset under the drive of the first elastic member 3. When the abutting part 2 abuts the closing part 4, the staff may knock over the trolley, causing it to tip over and the abutting part 2 to tend to move away from the closing part 4 along the second preset path L2. At this time, the first elastic member 3 can resist this tendency, so that the abutting part 2 can firmly abut the closing part 4. Even if the trolley tip over, the drawer 9 will not be thrown out, and the medical supplies in the drawer 9 will not be scattered all over the ground.
[0054] In some embodiments, the locking mechanism includes at least two abutment members 2, which are arranged in a circular pattern around the end of the first end of the closing member 4, and each abutment member 2 is movably connected to the seat 1 through a first elastic member 3.
[0055] If two abutment pieces 2 are provided, the two abutment pieces 2 are symmetrically arranged with the first preset path L1 of the closing piece 4 as the axis of symmetry; if three or more abutment pieces 2 are provided, these abutment pieces 2 may not be symmetrical about the first preset path L1, but when the closing piece 4 is in the first position, these abutment pieces 2 can be distributed in a circle with the position of the locking step 41 at the first end of the closing piece 4 as the center. During the process of the closing piece 4 moving from the second position to the first position, these abutment pieces 2 can be pushed open synchronously, and as the closing piece 4 continues to move, the ends of these abutment pieces 2 can synchronously pass over the end of the closing piece 4 and rebound, and at the same time abut against the locking step 41 at the first end of the closing piece 4, locking the closing piece 4 in the first position.
[0056] This application provides at least two abutting parts 2, which can abut against the closing part 4 in multiple directions, so that the closing part 4 is subjected to uniform force and the locking of the closing part 4 is more secure.
[0057] The abutting part 2 can be opened by the closing part 4 or the opening part 5.
[0058] The end of the abutment member 2 has a first abutment portion 21 and a second abutment portion 22.
[0059] The first end of the closing member 4 has a closing engagement portion 42. The closing engagement portion 42 and the outer periphery of the closing member 4 have a locking step 41. The closing engagement portion 42 and the first abutment portion 21 can form a movable contact to push the abutment portion 2 open. Specifically, when the closing member 4 is driven to move from the second position to the first position, the closing engagement portion 42 can push open the first abutment portion 21, so that the abutment portion 2 moves on the second preset path L2. As the closing member 4 continues to move, the first abutment portion 21 passes over the closing engagement portion 42 and rebounds, and abuts against the locking step 41, locking the closing member 4 in the first position.
[0060] Similarly, the first end of the opening member 5 is formed with an opening engagement part 51. The opening engagement part 51 and the second abutment part 22 can form a movable contact. When the opening member 5 is driven to move, it can push the abutment part 2 open. Specifically, when the opening member 5 is driven to move on the third preset path L3, the opening engagement part 51 can push open the second abutment part 22, so that the abutment part 2 moves on the second preset path L2 and leaves the locking step 41 to release the closing member 4. The closing member 4 can then be pulled back to the second position.
[0061] As a preferred embodiment, the first abutting part 21 is hook-shaped. The side of the first abutting part 21 facing the closing member 4 has a first abutting surface 211, and the side away from the closing member 4 has a locking surface 212. The first abutting surface 211 can make active contact with the surface of the closing mating part 42, which can be point contact, line contact, or surface contact. The locking surface 212 is perpendicular to the first preset path L1, and when the closing member 4 is in the first position, the locking surface 212 and the surface of the locking step 41 abut together, that is, the abutting member 2 locks the closing member 4. The locking surface 212 and the surface of the locking step 41 can make line contact or surface contact.
[0062] As a preferred embodiment, the second abutting part 22 has a second abutting surface 221 on the side facing the opening member 5. The second abutting surface 221 can make active contact with the opening mating part 51, which can be point contact, line contact or surface contact, so that the opening member 5 can push the abutting part 2 open.
[0063] In order to facilitate the design of the movement mode of the closing part 4, the abutting part 2 and the opening part 5, and to rationally plan the internal space of the seat body 1 and reduce the external size of the seat body 1, it is preferable that the first preset path L1 and the third preset path L3 are parallel, and the second preset path L2 and the first preset path L1 are perpendicular.
[0064] Optionally, the closing element 4 can be driven to slide or rotate in a straight line, and similarly, the opening element 5 can be driven to slide or rotate in a straight line.
[0065] The locking mechanism of this application also includes a second elastic element 6 and a third elastic element 7.
[0066] The second elastic element 6 is connected to the closing element 4 and the seat 1 respectively. The second elastic element 6 has the tendency to push the closing element 4 to move on the first preset path L1 and leave the seat 1. When the opening element 5 pushes open the abutment element 2, the closing element 4 is unlocked. The closing element 4 can rebound from the first position to the second position under the drive of the second elastic element 6. The drawer 9 connected to the closing element 4 can be ejected from the outside of the trolley at the same time.
[0067] The third elastic element 7 is connected to the opening element 5 and the seat 1 respectively. The third elastic element 7 has the tendency to push the opening element 5 to move on the third preset path L3 and leave the seat 1. After the opening element 5 pushes open the abutment element 2 and the closing element 4 rebounds to the second position, the operator removes the force applied to the opening element 5, and the opening element 5 resets under the drive of the third elastic element 7.
[0068] In this application, a first elastic element 3, a second elastic element 6, and a third elastic element 7 are respectively provided for the abutting part 2, the closing part 4, and the opening part 5, which can realize that the trolley drawer 9 can be closed with one push and opened with another push. The operator can perform the same operation on the closing part 4 and the opening part 5 to close or open the trolley drawer 9. Therefore, by assembling the locking mechanism of this application on the trolley, the operation of locking and opening the drawer 9 can be made convenient and quick.
[0069] As a preferred embodiment, the locking mechanism further includes a pusher 8, which is disposed on the first preset path L1. The second elastic member 6 is connected to the pusher 8 and the seat 1 respectively. When the opening member 5 is driven to push open the abutment 2 and make the abutment 2 leave the locking step 41, the pusher 8 pushes the closing member 4 back to the second position under the drive of the second elastic member 6.
[0070] Furthermore, the end of the abutment member 2 is also formed with a clearance step 23, and the push member 8 is formed with a push protrusion 81. When the closing member 4 is in the second position, the push protrusion 81 is driven by the second elastic member 6 and abuts against the clearance step 23, so that when the closing member 4 moves to the first position, the push member 8 can be pushed open.
[0071] Inside the seat 1, the abutment 2, closing 4, opening 5 and pushing 8 are assembled compactly, occupy little space, fit closely, trigger well, and can generate movement instantly.
[0072] The first elastic element 3 and / or the second elastic element 6 and / or the third elastic element 7 include a spring and a spring sheet. The first elastic element 3 can be disposed on the first preset path L1 or on the side of the first preset path L1, but its deformation direction is parallel to the extension direction of the first preset path L1. The design requirements of the second elastic element 6 and the third elastic element 7 can also be the same as those of the first elastic element 3, which will not be repeated here.
[0073] The second aspect of this application also provides a medical device, including a locking mechanism as described in the first aspect and a movable worktable; the movable worktable is provided with a drawer 9, the locking mechanism is disposed on the movable worktable, and the second end of the closing member 4 is connected to the drawer 9.
[0074] This medical device allows drawer 9 to be closed with a push and opened with a single button, making it convenient for staff to operate. It can also lock drawer 9 inside the mobile worktable to facilitate staff movement.
