All other embodiments, which are derived by a person skilled in the art based on the embodiments of the present invention, shall fall within the scope of protection of the embodiments of the present invention.
Example 1
Fig. 2 is a schematic structural diagram of an anti-disassembly quick-assembly device without a movable component according to a first embodiment of the present invention, fig. 3 is a schematic structural diagram of an anti-disassembly quick-assembly device with a movable component with a slider structure according to a first embodiment of the present invention, and fig. 4 is a schematic structural diagram of an anti-disassembly quick-assembly device with a movable component with a ball joint structure according to a first embodiment of the present invention, as shown in fig. 2, 3 and 4, including: a limiting part 21, a locking piece 22, a locking piece control part 23 and a movable part 24.
Wherein, the limiting component 21 comprises a mounting cavity 211, and the movable component 24 is mounted in the mounting cavity 211. The locking piece 22 is disposed between the movable component 24 and the inner wall of the installation cavity 211, the locking piece control component 23 is used for controlling the locking piece 22, so that the locking piece 22 moves into or out of a position matched with the inner wall of the installation cavity 211 to provide pressure for the movable component 24, and when the locking piece 22 is matched with the inner wall of the installation cavity 211 to provide pressure for the movable component 24, the movable component 24 can be extruded to lock the movable component 24.
More specifically, the mating surface of the locking piece 22 with the movable component 24 is a friction surface, and/or the mating surface of the locking piece 22 with the inner wall of the installation cavity on the side away from the movable component 24 is a friction surface.
In this embodiment, the movable member 24 includes any one of a movable member of a slider structure as shown in fig. 3 and a movable member of a ball joint structure as shown in fig. 4. Of course, in other implementations of the present embodiment, the movable member 24 may be another movable member, such as a shaft structure or a swing structure.
In this embodiment, the friction surface 221 of the lock block 22, i.e. the surface with friction force, may be a plane, and the cross section of the lock block 22 may be a wedge.
In this embodiment, as shown in fig. 2, 3 and 4, when the mating surface of the lock block 22 on the side far from the movable component 24 and the inner wall of the installation cavity is a friction surface, the friction force on the friction surface 221 is the friction force between two contact surfaces between the lock block 22 and the installation cavity 211; or the mounting cavity 211 or the lock block 22 may be provided with a structure for increasing the friction force of the friction surface 221, for example, two mutually contacting surfaces between the lock block 22 and the mounting cavity 211 may be surfaces having rough surfaces.
When the mating surface of the locking piece 22 and the movable component 24 is a friction surface, the friction surface is similar to that described above, and will not be described herein.
In this embodiment, the locking piece 22 is disposed in the mounting cavity 211, and the locking piece control part 23 is operated to control the movement of the locking piece 22, so that the locking piece 22 moves into or out of a position that cooperates with the inner wall of the mounting cavity 211 to provide pressure to the movable part 24, thereby locking the movable part 24 or unlocking the movable part 24.
In this embodiment, for better clarity, the installation cavity 211 may be divided into a locking groove 2111 and a limiting cavity 2112, where the locking groove 2111 is used for placing the locking piece 22, and a mating surface of the locking piece 22 on a side away from the movable component 24 with the locking groove 2111 is a friction surface, and the limiting cavity 2112 is used for installing the movable component 24.
As shown in fig. 2,3 and 4, the distance between the left and right sides of the locking groove 2111 is greater than the length of the locking piece 22, so that the locking piece 22 can move in the left and right directions in the drawing, that is, the locking piece 22 can move in the locking groove 2111.
In the drawing, when lock piece 22 is located on the left side of lock groove 2111 (on the side far from through hole 212), lock piece 22 is located exactly in lock groove 2111, that is, lock piece 22 is located between movable member 24 and the inner wall of installation cavity 211, and is located at a position where it cannot cooperate with the inner wall of installation cavity 211 to provide pressure to movable member 24, so that lock piece 22 cannot press movable member 24, and thus cannot lock movable member 24.
When lock piece 22 is located on the right side of lock groove 2111 (on the side close to through hole 212), a part of lock piece 22 protrudes from lock groove 2111, that is, lock piece 22 is located between movable member 24 and the inner wall of installation cavity 211 and is located at a position where it cooperates with the inner wall of installation cavity 211 to provide pressure to movable member 24, so that lock piece 22 presses movable member 24, thereby locking movable member 24; friction exists between the mating surface of lock block 22 and lock groove 2111 at friction surface 221 and where lock block 22 contacts movable member 24.
Further, in this embodiment, as shown in fig. 2, 3 and 4, the lock block control member 23 specifically includes a screw 231, the limiting member 21 includes a through hole 212, the lock block 22 includes a screw hole 222, and the screw 231 passes through the through hole 212 and cooperates with the screw hole 222.
The rotation of the screw 231 can drive the locking piece 22 to move in a direction approaching the through hole 212, and move into a position matching with the inner wall of the mounting cavity 211 to provide pressure for the movable component 24, so as to lock the movable component 24.
In this embodiment, in order to make the rotation of the screw 231 drive the locking piece 22 to move, as shown in fig. 2, 3 and 4, the screw 231 may be screwed in until the right side of the screw 231 is engaged with the outside of the limiting member 21 in the direction of the drawing, so that the screw 231 cannot move leftwards, and the screw 231 is continuously screwed in, so that the locking piece 22 is driven to move towards the direction approaching the through hole 212 (i.e. the rightward direction in the drawing). Of course, in other implementations of the present invention, the left side of the screw 231 may contact the inner wall of the locking groove 2111, so that the screw 231 can not move leftwards any more, and the screw 231 is screwed in, so that the locking piece 22 is driven to move in a direction approaching the through hole 212 (i.e., a rightward direction in the drawing).
When the lock block control part 23 includes the screw 231, the locking operation of the quick-setting device is to rotate the screw 231, which is not different from the locking method of the existing quick-setting device.
In addition, in this embodiment, the pressing of the screw 231 may drive the locking piece 22 to move away from the through hole 212, and move out of a position that cooperates with the inner wall of the mounting cavity 211 to provide pressure to the movable member 24, so as to release the locking of the movable member 24.
Specifically, during the locking process, the screw 231 is screwed into the screw 231 and the screw 231 is clamped or contacted with the limiting component 21, so that the screw 231 can drive the locking piece 22 to move towards the direction approaching to the through hole 212; in the unlocking process, the screw 231 needs to be first unscrewed, and since the locking piece 22 is pressed between the movable component 24 and the inner wall of the mounting cavity 211, the unscrewing screw 231 only moves the screw 231 to the right in the drawing, and if the locking of the movable component 24 is to be released, the screw 231 needs to be pressed to the left (i.e. towards the direction of the through hole), so as to drive the locking piece 22 to move in the direction away from the through hole 212 (i.e. towards the left in the drawing) to release the locking of the movable component 24.
As described above, the unlocking operation of the quick-assembly device requires pressing and unlocking after the screw 231 is unscrewed, and simply unscrewing the screw 231 does not unlock the movable member 24, thereby achieving the effect of preventing incorrect disassembly. Compared with the prior quick assembly device, the unlocking process in the embodiment not only needs to unscrew the quick assembly screw, but also increases the step of pressing the quick assembly screw, thereby preventing the situation that the movable part is loosened due to misoperation of an operator or loosening of the quick assembly screw, and particularly, the structure is arranged in the whole instrument aiming at some key parts, so that the anti-misoperation effect can be reflected.
Specifically, in this embodiment, the lock block control part 23 may be a quick-mounting screw. Of course, in other implementations of the invention, the lock block control member 23 may be of other similar construction including a screw 231.
Specifically, in this embodiment, the inner surface of the through hole 212 is smooth, and/or the diameter of the through hole 212 is larger than the diameter of the portion of the screw 231 that mates with the through hole 212.
As shown in fig. 2, 3 and 4, the mating surface of the locking piece 22 on the side far from the movable member 24 with the locking groove 2111 is a friction surface 221, and the axial direction of the screw 231 is not parallel to the direction of the friction surface 221, when the locking piece 22 moves in the direction approaching the through hole 212 (i.e. the rightward direction in the drawing), the locking piece 22 also moves in the direction approaching the movable member 24 at the same time, the screw hole 222 on the locking piece 22 also moves in the same direction, the diameter of the through hole 212 is larger than the diameter of the mating part of the screw 231 with the through hole 212, and a moving space can be provided for the screw 231, so that the movement of the screw 231 matches the movement of the screw hole 222. Further, the cross-section of the through-hole 212 may be rounded rectangular.
In fig. 2, 3 and 4, if the plane of the lock block 22 matching with the lock groove 2111 on the side far from the movable member 24 is set to be horizontal in the drawing, and the plane of the lock block 22 on the side near to the movable member 24 is set to be horizontal, the purpose of locking the movable member 24 can be achieved as well, and the moving direction of the lock block 22 is the same as the axial direction of the through hole 212; in addition, since the movable member 24 is to be moved within the installation cavity 211, there is necessarily a movement gap between the movable member 24 and the inner wall of the installation cavity 211, and thus it can be seen that even if the cross section of the lock block is not wedge-shaped (e.g., rectangular), it is sufficient to be able to move between the movable member 24 and the inner wall of the installation cavity 211, and thus to be able to cooperate with the inner wall of the installation cavity 211 to provide a form of pressure to the movable member 24.
In summary, the above specific structure is only a preferred technical solution, and since the existing movable component is installed in the limiting component, there is a movable gap, so long as the lock block 22 can be pushed into the movable gap between the movable component 24 and the inner wall of the installation cavity 211.
In the quick-mounting device provided in the above embodiment, for some very special situations, such as simply screwing out the lock control member 23 (such as a quick-mounting screw) and not pressing the lock control member 23, when the movable member 24 is not yet unlocked, and when the external force applied to the movable member 24 is extremely large or the self-gravity is extremely large, and the moving direction of the movable member 24 is the same as the moving direction of the lock 22 during unlocking, the force applied to the movable member 24 may affect the force applied to the lock 22 due to the direct contact between the movable member 24 and the lock 22, and even the friction force between the lock 22 and the inner wall of the mounting cavity 211 may be overcome, the movable member 24 drives the lock 22 to displace, so that the locking of the movable member 24 is released.
Taking the ball joint structure as an example, if the lock block control member 23 of fig. 4 is not screwed again after being screwed out in the above embodiment, the locking of the movable member 24 is maintained only by the friction force on the friction surface 221, and if the ball joint structure is subjected to a large rightward force on the portion outside the installation cavity 211 in fig. 4, a large force is generated on the side of the movable member 24 of the ball joint structure, which contacts the lock block 22, and this force may cause the lock block 22 to overcome the friction force of the friction surface 221, so that the lock block 22 moves leftward (i.e., in the direction away from the through hole 212), and the locking of the movable member 24 of the ball joint structure is released.
Fig. 5 is a schematic structural diagram of a quick-assembly device for preventing incorrect disassembly according to a second embodiment of the present invention, in which fig. 5 is an exemplary illustration of a movable component 24 as a movable component of a ball joint structure, and as shown in fig. 5, the quick-assembly device for preventing incorrect disassembly further includes: the connecting block 25, the connecting block 25 sets up the locking piece 22 with between the movable part 24, so that the locking piece 22 passes through the connecting block 25 with the movable part 24 cooperates, the removal of connecting block 25 can not drive the locking piece 22 removes, thereby makes the activity of movable part 24 can not influence locking piece 22, and then has guaranteed the validity of the movable part 24 locking of quick-mounting device, has avoided the emergence of above-mentioned condition.
In this embodiment, the mating surface of the lock block 22 with the connection block 25 may be a friction surface, or the mating surface of the lock block 22 with the mounting cavity 211 on the side far from the connection block 25 may be a friction surface.
Specifically, the mounting cavity 211 includes a connection hole disposed between the lock block 22 and the movable member 24, and the connection block 25 is disposed in the connection hole, and the movable direction of the connection block is limited by the connection hole, so that the movable direction of the connection block 25 is different from the movable direction of the lock block 22, so that the movement of the connection block 25 does not drive the lock block 22 to move.
In addition, in order to achieve a better locking effect, a contact position between the connection block 25 and the movable member 24 may be provided with a friction structure for increasing friction.
In addition, in any of the embodiments, the number of the movable components, the connecting blocks and other structural members in the anti-false disassembly quick assembly device can be flexibly configured according to the needs.
The embodiment of the invention provides a medical instrument, which comprises one or more anti-misdisassembly quick-assembly devices.
For the medical instrument, the quick-mounting device can conveniently adjust the position, the posture and the like of the medical instrument, so that different requirements in the operation are met, and if the quick-mounting device on the medical instrument is in a false disassembly condition, the movable part calibrated in the space position is displaced, so that the safety risk is brought to the operation.
Therefore, in this embodiment, the anti-misdisassembly quick assembly device in the above embodiment is used on a medical apparatus and instruments, and the anti-misdisassembly quick assembly device can maintain a locking state through a friction force on a friction surface, and does not need to maintain the locking state through a locking piece control component, if the locking piece control component is operated so as not to cause movement of the locking piece, the locking of the movable component is not released, thereby achieving the anti-misdisassembly effect, and further avoiding the safety risk brought by the misdisassembly of the quick assembly device into an operation as much as possible.
