Description

Technical Field

[0001] This disclosure relates to the field of medical devices, and in particular to an apparatus and method for assembling and separating medical components. Background Technology

[0002] In the daily work of a hospital, it is often necessary to combine disposable medical devices and reusable medical devices into medical assemblies. After use, the disposable medical devices need to be separated from the medical assemblies and discarded, and then new disposable medical devices need to be combined with reusable medical devices for reuse. Therefore, the operation of separating and combining medical devices is required frequently.

[0003] Currently, medical staff mainly separate and assemble medical components by using their hands to directly contact reusable medical equipment as well as disposable and reusable medical equipment.

[0004] The existing methods of separation and combination have the following problems: many operation steps, long operation time, and low work efficiency; easy to cause infection of medical staff or infection between patients, and contamination of reusable medical equipment by disposable medical equipment, high requirements for subsequent disinfection operations, increased disinfection frequency of reusable medical equipment, reduced use efficiency, and thus increased maintenance costs of reusable medical equipment.

[0005] In summary, there is a need for a replacement device that can improve work efficiency, is easy to use, and reduces hospital-acquired infections, for separating and assembling medical components. Summary of the Invention

[0006] This disclosure is made in view of the above-mentioned state of the prior art, and its purpose is to provide a device and method for combining and separating medical components that can improve work efficiency, facilitate use, and reduce hospital-acquired infections.

[0007] Therefore, a first aspect of this disclosure provides a device for separating and assembling a medical assembly, which is a device for separating and assembling an assembly formed by a separating member and a fixing member. The device includes a support structure, a locking structure, and an elastic structure. The support structure is used to house the locking structure and the elastic structure. The elastic structure is configured to act on the locking structure to lock and / or unlock the fixing member. The locking structure includes a central member for inserting into the assembly, a first locking portion for locking and / or unlocking the fixing member, and a second locking portion for locking and / or unlocking the central member. The central member is movably disposed in the support structure, the first locking portion is movably disposed in the central member, and the second locking portion is movably disposed in the support structure. In a first press, the assembly is pressed against the central member, and the fixing member pushes the central member to lock the fixing member with the first locking portion and the second locking portion locks the central member, thereby replacing the separating member in the assembly. In a second press, the assembly is pressed against the central member to unlock the central member with the second locking portion and the first locking portion unlocks the fixing member, thereby removing the assembly.

[0008] In the first aspect of this disclosure, the assembly to be separated and joined is placed on the central member. A first pressing of the assembly locks the fixing member with a first locking part and the central member with a second locking part. With both the fixing member and central member locked, the separating member within the assembly can be replaced, i.e., a new separating member replaces the old one to form a new assembly with the fixing member. A second pressing of the assembly unlocks the central member with the second locking part and the fixing member with the first locking part. Throughout the process of separating and joining the assembly, the assembly is always operated indirectly through the separating member. When replacing the separating member, the user only needs to contact the separating member and does not need to contact other components. This improves work efficiency, ease of use, and reduces the risk of hospital-acquired infections.

[0009] Additionally, in the apparatus according to the first aspect of this disclosure, optionally, the fixing member includes a connecting line, the support structure includes a first opening for passage through the connecting line, and the center member includes a second opening for passage through the connecting line. In this case, when the assembly includes a connecting line, the assembly can be easily assembled and disassembled by the assembly / disassembly device.

[0010] Additionally, in the apparatus according to the first aspect of this disclosure, optionally, the second locking part includes a fixed part fixed to the support structure and a movable part movable to the support structure, the movable part being combined with the fixed part and the movable part having a tendency to move around the fixed part, the movable part locking and / or unlocking the central member; or, the second locking part includes a fixed part fixed to the support structure, a movable part movable to the support structure, and a driving part abutting against the movable part and providing a force to the movable part, the direction of the force being offset from the fixed part towards the central member, the movable part having a tendency to move around the fixed part under the action of the driving part, the movable part locking and / or unlocking the central member. In this case, since the movable part tends to move around the fixed part, when the movable part moves around the fixed part, the center member of the movable part can be locked and / or unlocked; or, by the drive part acting on the movable part in a manner that deviates from the fixed part, the movable part can tend to move around the fixed part, and when the movable part moves around the fixed part, the center member of the movable part can be locked and / or unlocked.

[0011] Additionally, in the apparatus according to the first aspect of this disclosure, optionally, the central member includes a first limiting portion, and the first locking portion is movably disposed on the first limiting portion. In this case, when the first locking portion is moved to the first limiting portion, the first locking portion can lock and / or unlock the fixing member.

[0012] Additionally, in the apparatus according to the first aspect of this disclosure, optionally, the support structure has a protrusion on the side near the center member that acts on the first locking portion to lock the fixing member. In this case, the protrusion allows the first locking portion to move towards the end near the fixing member in the first limiting portion, thereby enabling the first locking portion to lock the fixing member.

[0013] Furthermore, in the apparatus according to the first aspect of this disclosure, optionally, after the first locking part locks the fixing member and before the second locking part locks the center member, the assembly and the center member spring back under the action of the elastic structure; after the second locking part unlocks the center member and before the first locking part unlocks the fixing member, the assembly and the center member spring back under the action of the elastic structure. In this case, the second locking part can lock and / or unlock the center member through the springback action of the elastic structure.

[0014] Additionally, in the apparatus according to the first aspect of this disclosure, optionally, the central member includes a locking region, and the movable part acts on the locking region to lock and / or unlock the central member by the second locking part. In this case, the second locking part can lock and / or unlock the central member.

[0015] Additionally, in the apparatus according to the first aspect of this disclosure, optionally, the central member further includes a second limiting portion, and the support structure restricts the movement of the central member within the support structure by abutting against the second limiting portion. In this case, the second limiting portion enables the central member to maintain a relatively stable state within the support structure.

[0016] Additionally, in the apparatus according to the first aspect of this disclosure, optionally, the support structure is configured to block the first locking portion so that the first locking portion is held in the first limiting portion. In this case, the opening and closing device can be used for a long period of time.

[0017] Furthermore, in the device according to the first aspect of this disclosure, optionally, the first limiting part is a through hole with different diameters at both ends, and the first locking part is a sphere. The diameter of the first locking part is larger than the diameter of the hole at the end of the first limiting part near the fixing member and smaller than the diameter of the hole at the end of the first limiting part away from the fixing member. In this case, the first locking part can be prevented from disengaging from the first limiting part when it moves towards the end of the first limiting part near the fixing member.

[0018] Additionally, in the apparatus according to the first aspect of this disclosure, optionally, the first locking portion is at least partially exposed outside the first limiting portion. In this case, when the center member moves in the insertion direction or the withdrawal direction, the first locking portion can abut against the support structure and / or against the fixing member, thereby enabling the center member and the assembly to move together during the pressing or rebounding of the center member, thereby enabling the first locking portion to lock and / or unlock the fixing member.

[0019] Additionally, in the apparatus according to the first aspect of this disclosure, optionally, the movable part includes at least two sets of locking structures that act on the locking region to lock and / or unlock the central member. In this case, the second locking part can lock and / or unlock the central member through the cooperation of the locking structure and the locking region, and the presence of at least two sets of locking structures allows the opening and closing device to open and close multiple times.

[0020] Additionally, in the apparatus according to the first aspect of this disclosure, optionally, the locking region includes a first track, a second track, a third track, and a fourth track, which are sequentially connected to form a complete loop. The locking region has a stepped structure at the connection between at least one pair of adjacent tracks, and the movable part is in close contact with the multiple tracks of the locking region in the inward direction of the central member. In this case, after the movable part passes through the stepped structure, it cannot reverse through the stepped structure to return to the previous track. That is, under the combined action of the stepped structure and the multiple tracks of the locking region in the inward direction of the movable part, the movable part can move sequentially between the multiple tracks.

[0021] Additionally, in the apparatus according to the first aspect of this disclosure, optionally, when the end of the first locking portion near the fixing member is exposed outside the first limiting portion, the first locking portion engages with the fixing member. In this case, the first locking portion can lock the fixing member during the pressing down of the assembly.

[0022] Additionally, in the device according to the first aspect of this disclosure, optionally, the latching structure includes a stop and a locking angle, and the locking area includes a horizontal side and a vertical side. When the stop abuts against the vertical side and the locking angle abuts against the horizontal side, the second locking part locks the central member; when the locking angle abuts against the vertical side or the stop abuts against the horizontal side, the second locking part unlocks the central member. In this case, by changing the contact relationship between the locking angle and the stop with the horizontal and vertical sides, the locking and unlocking states of the second locking part and the central member can be switched.

[0023] Furthermore, in the apparatus according to the first aspect of this disclosure, optionally, the locking region has the stepped structure at the connection between adjacent tracks. In this case, after the splitting and joining device performs multiple splitting and joining operations, the tendency of the moving part to move towards a vertical position may weaken or even disappear. At this time, guided by the stepped structure between each pair of adjacent tracks, the moving part can move in the loop formed by multiple tracks.

[0024] Furthermore, in the apparatus according to the first aspect of this disclosure, optionally, the connection point between the fourth track and the inner side of the first track is offset from the fixing portion in the direction of the fourth track, and the connection point between the second track and the outer side of the third track is offset from the fixing portion in the direction of the second track, and the locking region has the stepped structure at the connection between the third track and the fourth track. In this case, when the assembly is pressed down for the first time, the movable part can move along the first track without entering the fourth track; when the assembly is pressed down for the second time, the movable part can move along the third track without entering the second track; and the structure of the locking region can be simplified.

[0025] Additionally, in the apparatus according to the first aspect of this disclosure, optionally, the locking region has the stepped structure at the connection between the second track and the third track, the connection between the third track and the fourth track, and the connection between the fourth track and the first track. In this case, the movable part can move along the first track without entering the fourth track when the assembly is first pressed down; and the movable part can move along the third track without entering the second track and then move from the third track to the fourth track when the assembly is pressed down a second time.

[0026] The second aspect of this disclosure provides a method for separating and assembling a medical assembly, which is a method for separating and assembling a medical assembly using the device involved in the first aspect of this disclosure, comprising: first pressing the assembly against the device to lock a retainer to the device; replacing the separator in the assembly; second pressing the assembly against the device to unlock the retainer from the device; and removing the assembly.

[0027] In the second aspect of this disclosure, an assembly to be separated and joined is placed on the device. A first pressing of the assembly locks the fixing member with a first locking part and the center member with a second locking part. With the first locking part locking the fixing member and the second locking part locking the center member, the separating member within the assembly can be replaced, i.e., a new separating member replaces the old one to form a new assembly with the fixing member. A second pressing of the assembly unlocks the center member with the second locking part and unlocks the fixing member with the first locking part. Throughout the process of separating and joining the assembly, the assembly is always operated indirectly by manipulating the separating member. When replacing the separating member, the user only needs to contact the separating member and does not need to contact other components. Furthermore, the user only needs to perform two operations: pressing down, replacing the separating member, and removing the assembly. This improves work efficiency, ease of use, and reduces the risk of hospital-acquired infections.

[0028] Additionally, in the method according to the second aspect of this disclosure, optionally, during the locking process between the fastener and the device, the assembly and the central member spring back under the action of the elastic structure; during the unlocking process between the fastener and the device, the assembly and the central member spring back under the action of the elastic structure. In this case, the springback action of the elastic structure enables the second locking part to lock and / or unlock the central member.

[0029] This disclosure provides a device and method that can improve work efficiency, is easy to use, and reduce hospital-acquired infections. Attached Figure Description

Detailed Implementation

[0055] Hereinafter, preferred embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. In the following description, the same reference numerals are used for the same components, and repeated descriptions are omitted. Furthermore, the drawings are merely schematic diagrams, and the proportions of the components or the shapes of the components may differ from actual figures.

[0056] It should be noted that the terms "comprising" and "having" and any variations thereof in this disclosure, such as a process, method, system, product, or device that includes or has a series of steps or units, are not necessarily limited to those steps or units that are explicitly listed, but may include or have other steps or units that are not explicitly listed or that are inherent to such processes, methods, products, or devices.

[0057] The device for separating and merging medical assemblies disclosed herein may also be referred to as a separating and merging device, or simply as a device. The medical assemblies disclosed herein may also be referred to simply as assemblies. The method for separating and merging medical assemblies disclosed herein may also be referred to simply as a separating and merging method.

[0058] In some examples, the separation and merging device can also be used to separate and merge non-medical assemblies, but is preferred for separating and merging medical assemblies. Therefore, the following description focuses primarily on separating and merging medical assemblies.

[0059] The apparatus and method for combining and separating medical components involved in this disclosure will be described in detail below with reference to the accompanying drawings and several specific embodiments.

[0060] Figure 1This is a schematic diagram showing the assembly 2 involved in this disclosure about to be inserted into the disassembly / removal device 1, see [link / reference]. Figure 1 The direction in which the assembly 2 is inserted (i.e., the insertion direction or the pressing direction) will be referred to as the insertion direction D1. Figure 2 This is a schematic diagram showing the separation component 20 as disclosed herein being extracted from the assembly 2, see [link to schematic diagram]. Figure 2 The direction in which the separating member 20 is pulled out (i.e., the extraction direction or the springback direction) will be referred to as the extraction direction D2. The insertion direction D1 is opposite to the extraction direction D2.

[0061] See Figure 1 and Figure 2 In some examples, assembly 2 can be formed by combining the separator 20 and the fastener 21. In some examples, the separator 20 and the fastener 21 can be connected by a simple snap-fit, that is, assembly 2 can be formed by combining the separator 20 and the fastener 21 by a simple snap-fit.

[0062] In some examples, a simple snap-fit ​​can mean that when the separator 20 is pressed down toward the retainer 21 in the insertion direction D1, the separator 20 and the retainer 21 can be combined to form a combination 2, and when the separator 20 is pulled out of the combination 2 in the extraction direction D2, the separator 20 and the retainer 21 can be separated.

[0063] In some examples, the connection between the separator 20 and the fixing member 21 can be a threaded connection. In this case, the separator 20 can be screwed into the fixing member 21 to be combined with the fixing member 21, or unscrewed out of the fixing member 21 to be separated from the fixing member 21.

[0064] In some examples, the separator 20 may be a disposable medical device, such as a disposable expander. In other examples, the separator 20 may be a non-disposable medical device that needs to be replaced.

[0065] In some examples, the fastener 21 may be a non-disposable medical device. In some examples, a non-disposable medical device may also be referred to as a reusable medical device, that is, a medical device that can be reused, such as a reusable examination endoscope.

[0066] See Figure 1 and Figure 2 In some examples, the separation and assembly 2 can refer to the separation and replacement of the separation component 20 from the assembly 2 by means of the separation and assembly device 1, and then the replacement separation component 20 and the fixing component 21 are combined to form the assembly 2 for the next use.

[0067] Figure 3 This illustrates the scope of this disclosure. Figure 1 A magnified view of region a in the image.

[0068] See Figure 3 In some examples, the fastener 21 may include a connecting wire 210, which may be a line for connecting the fastener 21 to other devices, such as a power line or a signal transmission line.

[0069] Figure 4 This is an exploded view of the separating and merging device 1 involved in this disclosure.

[0070] See Figure 4 In some examples, the opening and closing device 1 may include a support structure 10, a locking structure 11, and an elastic structure 12. The support structure 10 may be used to install the locking structure 11 and the elastic structure 12.

[0071] In some examples, the interior of the support structure 10 may be provided with a locking structure 11 and an elastic structure 12.

[0072] In some examples, the resilient structure 12 can be configured to act on the latching structure 11 to lock and / or unlock the fastener 21. That is, the latching structure 11 and the resilient structure 12 can cooperate to lock and / or unlock the fastener 21.

[0073] See Figure 4 In some examples, the locking structure 11 may include a center member 15, a first locking part 16, and a second locking part 17.

[0074] In some examples, the locking structure 11 locking and / or unlocking fastener 21 may refer to a first locking part 16 locking and / or unlocking fastener 21, and a second locking part 17 locking and / or unlocking center member 15. In this case, the assembly 2 can be separated and joined.

[0075] In some examples, the process of using the disassembly and assembly device 1 to disassemble and assemble assembly 2 may refer to the initial pressing of assembly 2 against center member 15, and fixing member 21 pushing center member 15 to lock fixing member 2 with first locking part 16 (hereinafter, the state of first locking part 16 locking fixing member 21 may also be referred to as the preliminary locking state), and locking center member 15 with second locking part 17 (hereinafter, the state of second locking part 17 locking center member 15 may also be referred to as the fully locked state), so as to replace the separator 20 in assembly 2. In some examples, the fully locked state may refer to the formation of a firm connection between fixing member 21 and disassembly and assembly device 1, at which point the separator 20 can be manually separated from fixing member 21 for replacement of separator 20.

[0076] Furthermore, the assembly 2 is pressed down a second time onto the center member 15, causing the second locking part 17 to unlock the center member 15 (this state of the second locking part 17 unlocking the center member 15 can also be referred to as the initial unlocking state), and causing the first locking part 16 to unlock the fixing member 21 (this state of the first locking part 16 unlocking the fixing member 21 can also be referred to as the fully unlocking state), so as to remove the assembly 2. In this case, during the replacement of the separating part 20, the user only needs to touch (e.g., hold) the separating part 20, put the separating part 20 onto the fixing member 21 to form the assembly 2, and then press the assembly 2 down onto the center member 15 to separate the assembly 2 from the separating and joining device 1, so as to remove the assembly 2. This improves work efficiency and ease of use, and reduces the possibility of hospital-acquired infections.

[0077] In some examples, the splitting device 1 may be in its initial state before the first pressing of assembly 2 onto center member 15 (i.e., before splitting assembly 2 using splitting device 1).

[0078] In some examples, after the first locking part 16 locks the fixing member 21 and before the second locking part 17 locks the center member 15, the assembly 2 and the center member 15 can spring back under the action of the elastic structure 12. In this case, the second locking part 17 can lock the center member 15 by the springback action of the elastic structure 12.

[0079] Furthermore, after the second locking part 17 unlocks the center member 15, and before the first locking part 16 unlocks the fixing member 21, the assembly 2 and the center member 15 can spring back under the action of the elastic structure 12. In this case, the second locking part 17 can unlock the center member 15 through the springback action of the elastic structure 12.

[0080] See Figure 4 In some examples, the support structure 10 may be modular. In some examples, when the support structure 10 is modular, it may include a first support member 13 and a second support member 14, which may be combined to form the support structure 10.

[0081] In some examples, the support structure 10 can be a single piece, and the interior of the support structure 10 can be provided with a locking structure 11 and an elastic structure 12.

[0082] In some examples, the first support 13 can be used to provide space for the locking structure 11 and the elastic structure 12. In this case, it can provide a support point for the elastic structure 12.

[0083] In some examples, the center member 15 can be used to insert the assembly 2. Specifically, the center member 15 can have a hollow channel. In this case, the assembly 2 can be inserted into the splitting device 1.

[0084] In some examples, the insertion of assembly 2 into center member 15 may refer to the insertion of the fixing member 21 portion of assembly 2 into center member 15.

[0085] See Figure 3 In some examples, the fixing member 21 pushing the center member 15 may mean that the fixing member 21 may have an expansion portion 212 that abuts against the center member 15. In this case, during the process of pressing the assembly 2 against the center member 15, the fixing member 21 can push the center member 15 so that the assembly 2 moves together with the center member 15.

[0086] In some examples, the fastener 21 pushing the center member 15 may mean that the fastener 21 does not have an expansion portion 212, but the center member 15 has a protruding portion inside, and the portion of the fastener 21 inserted into the center member 15 can abut against this protruding portion. In this case, the fastener 21 can also push the center member 15 during the process of pressing the assembly 2 against the center member 15, so that the assembly 2 moves together with the center member 15.

[0087] In some examples, the center member 15 is movably disposed within the support structure 10. In some examples, the movability of the center member 15 within the support structure 10 may mean that the center member 15 is movably disposed within the first support member 13. Specifically, the center member 15 can move within the first support member 13 in the directions of insertion direction D1 and withdrawal direction D2.

[0088] See Figure 2 In some examples, the support structure 10 may include a first opening 100 for passage of the connecting line 210. In other words, the first opening 100 can be accessed through the connecting line 210.

[0089] Figure 5 This is a schematic diagram of the structure of the first support member 13 involved in this disclosure, wherein, in order to better show the internal structure of the first support member 13, some parts and lines that may cause obstruction or misunderstanding are omitted. Figure 6 This is a schematic diagram of the structure of the second support member 14 involved in this disclosure.

[0090] See Figure 5 and Figure 6 In some examples, the support structure 10 may include a first opening 100, meaning that the first support member 13 may include the first opening 100 and the second support member 14 may include the first opening 100. That is, the first opening 100 may be formed on the same side of the first support member 13 and the second support member 14.

[0091] In some examples, the second support 14 can be fixed to the first support 13. In this case, a support point for force can be provided for the elastic structure 12.

[0092] See Figure 6 In some examples, the second support 14 may include a first groove 140. In some examples, the first groove 140 may mate with the elastic structure 12 to limit the position of the elastic structure 12 in the second support 14 and may be used to position the elastic structure 12. In this case, a support point for force can be provided for the elastic structure 12.

[0093] See Figure 6 In some examples, the second support 14 may also include a connecting handle 141, which can be connected to an external bracket to form a fixed connection between the separating device 1 and the external bracket. In this case, when inserting or removing the assembly 2 or the separating member 20, the external bracket can provide a reaction force to the separating device 1. This improves the ease of manually separating the fixing member 21 and the separating member 20.

[0094] Figure 7 This is a schematic diagram showing the structure of the central component 15 involved in this disclosure.

[0095] See Figure 7 In some examples, the center member 15 may include a second opening 150 for the connection line 210. In this case, when the fastener 21 includes the connection line 210, the assembly 2 can be easily joined and disassembled by the disassembly and assembly device 1 through the first opening 100 and the second opening 150.

[0096] In some examples, the fastener 21 may not include the connecting line 210. In this case, the support structure 10 may not include the first opening 100, and the center member 15 may not include the second opening 150. In this case, the processing steps of the support structure 10 and the center member 15 can be simplified.

[0097] See Figure 7 In some examples, the center member 15 may also include a second groove 151 for positioning the elastic structure 12. In some examples, the center member 15 may be fitted onto the elastic structure 12 through the second groove 151.

[0098] In some examples, the elastic structure 12 can act on the center member 15. In this case, when the pressing assembly 2 moves in the insertion direction D1, the elastic structure 12 is compressed, so that the elastic structure 12 can rebound in the withdrawal direction D2, and thus act on the center member 15 to make the center member 15 move in the withdrawal direction D2.

[0099] See Figure 4In some examples, preferably, the number of elastic structures 12 can be two.

[0100] In some examples, the number of elastic structures 12 can be multiple. In some examples, the number of second grooves 151 can be equal to the number of elastic structures 12. In some examples, the number of first grooves 140 can be equal to the number of elastic structures 12.

[0101] In some examples, multiple elastic structures 12 can be arranged symmetrically. In this case, the central member 15 can be subjected to relatively balanced forces when it moves within the first support member 13.

[0102] In some examples, the elastic structure 12 can be, for example, a spring. In other examples, the elastic structure 12 can be a component with elasticity. In this case, the elastic structure 12 can have a rebounding effect.

[0103] In some examples, the first locking part 16 can be used to lock and / or unlock the fastener 21.

[0104] See Figure 7 In some examples, the center member 15 may also include a first limiting part 152 for setting the first locking part 16.

[0105] In some examples, the first locking part 16 is movably disposed on the center member 15. In some examples, the first locking part 16 being movably disposed on the center member 15 may mean that the first locking part 16 is movably disposed on the first limiting part 152. Specifically, the first locking part 16 can move within the first limiting part 152. In this case, when the first locking part 16 is active within the first limiting part 152, the first locking part 16 can lock and / or unlock the fixing member 21.

[0106] In some examples, the first limiting portion 152 can be a through hole with different diameters at both ends. In some examples, the first locking portion 16 can be, for example, a sphere. In some examples, the diameter of the first locking portion 16 can be larger than the diameter of the hole at the end of the first limiting portion 152 closest to the fixing member 21. In some examples, the diameter of the first locking portion 16 can be smaller than the diameter of the hole at the end of the first limiting portion 152 furthest from the fixing member 21. In this case, the first locking portion 16 can be prevented from disengaging from the first limiting portion 152 when it moves towards the end closest to the fixing member 21.

[0107] In some examples, the support structure 10 can be configured to block the first locking part 16 so that the first locking part 16 is held in the first limiting part 152. In this case, the opening and closing device 1 can be used for a long time.

[0108] In some examples, the side of the support structure 10 near the center member 15 may have a protrusion 101 that acts on the first locking part 16 to lock the fastener 21.

[0109] See Figure 5 In some examples, the support structure 10 may have a protrusion 101, which means that the first support member 13 of the support structure 10 may have a protrusion 101 on the side near the center member 15. In this case, the protrusion 101 enables the first locking member 16 to move in the first limiting member 152 toward the end near the fixing member 21, thereby enabling the first locking member 16 to lock the fixing member 21.

[0110] In some examples, the protrusion 101 may be formed by the side of the support structure 10 near the center member 15 protruding towards the center member 15.

[0111] In some examples, the support structure 10 can be configured to block the first locking part 16. This means that when the disengagement device 1 is in an operating state or not, and the disengagement device 1 is shaken, tilted, or inverted, the support structure 10 can prevent the first locking part 16 from disengaging from the end of the first limiting part 152 away from the fixing member 21. Specifically, for example, when the first locking part 16 is a ball, the maximum vertical distance from the support structure 10 to the center member 15 can be less than the radius of the first locking part 16; the support structure 10 can extend at least halfway beyond the first locking part 16 in the withdrawal direction D2.

[0112] In some examples, the first locking portion 16 may be at least partially exposed outside the first limiting portion 152. Specifically, for example, when the first limiting portion 152 is a through hole and the first locking portion 16 is a ball, the diameter of the first locking portion 16 is greater than the hole depth of the first limiting portion 152. In this case, when the center member 15 moves in the insertion direction D1 or the withdrawal direction D2, the first locking portion 16 can abut against the support structure 10 and the fixing member 21, thereby enabling the center member 15 and the assembly 2 to move together during the pressing or rebound of the center member 15, thereby enabling the first locking portion 16 to lock and / or unlock the fixing member 21.

[0113] In some examples, when the end of the first locking part 16 near the fastener 21 is exposed outside the first limiting part 152, the first locking part 16 can engage the fastener 21. In this case, the first locking part 16 can lock the fastener 21 during the pressing of the assembly 2.

[0114] See Figure 3In some examples, the fastener 21 may also include a third groove 211 for mating with the first locking part 16. In some examples, the first locking part 16 engaging the fastener 21 may refer to the third groove 211 of the first locking part 16 engaging the fastener 21.

[0115] See Figure 7 In some examples, the center member 15 may also include a second limiting portion 153, which the support structure 10 can abut against to restrict the movement of the center member 15 within the support structure 10. In this case, the second limiting portion 153 enables the center member 15 to maintain a relatively stable state within the support structure 10.

[0116] See Figure 7 In some examples, the second limiting portion 153 may be formed by the center member 15 extending into and connecting with the second groove 151 from the side near the second groove 151.

[0117] In some examples, the relatively stable state of the center member 15 within the support structure 10 can mean that when the assembly 2 is disassembled using the disassembly and assembly device 1, during the pressing process, the center member 15 moves in the insertion direction D1 under the push of the fixing member 21; during the rebound process, the center member 15 moves in the extraction direction D2 under the action of the elastic structure 12. In this case, the second limiting part 153 can keep the center member 15 within the support structure 10.

[0118] In some examples, the second locking part 17 can lock the center member 15. In some examples, the second locking part 17 can unlock the center member 15.

[0119] In some examples, the second locking part 17 is movably disposed in the support structure 10.

[0120] Figure 8A This is a schematic diagram showing the structure of the second locking part 17 involved in this disclosure. Figure 8B This is a schematic diagram showing the structure in which the second locking part 17 involved in this disclosure provides force through the driving part 172. Figure 9 This is a schematic diagram showing a modified example of the second locking part 17 involved in this disclosure.

[0121] See Figure 8A and Figure 9In some examples, the second locking part 17 may include a fixed part 170 fixed to the support structure 10 and a movable part 171 movable to the support structure 10. In some examples, the movable part 171 may be combined with the fixed part 170, and the movable part 171 may have a tendency to move around the fixed part 170. In some examples, the movable part 171 may lock and / or unlock the center member 15. In this case, since the movable part 171 has a tendency to move around the fixed part 170, when the movable part 171 moves around the fixed part 170, the movable part 171 can lock and / or unlock the center member 15.

[0122] In some examples, the tendency of the movable part 171 to move can mean that the movable part 171 has a tendency to rotate around the fixed part 170. In some examples, the direction of rotation of the movable part 171 around the fixed part 170 can be called the rotation direction D3. In this case, the movable part 171 can move within the support structure 10.

[0123] In some examples, the fixed part 170 may not provide a force to the movable part 171 to give the movable part 171 a tendency to move, but the force may be provided to the movable part 171 by another component.

[0124] Figure 10 This is a schematic diagram showing a modified example of the second locking part 17 involved in this disclosure, in which the driving part 172 provides force. In order to highlight the positional relationship between the driving part 172, the movable part 171, and the center member 15, some parts and lines that may cause obstruction or misunderstanding have been omitted.

[0125] See Figure 8B and Figure 10 In some examples, the second locking part 17 may further include a driving part 172. In some examples, the driving part 172 may abut against the movable part 171 and provide a force to the movable part 171. In some examples, the direction of the force may be offset towards the center member 15 from the fixed part 170.

[0126] In some examples, the movable part 171, under the action of the driving part 172, may tend to move around the fixed part 170 as the center. Specifically, see... Figure 8B The drive unit 172 can be disposed between the fixed part 170 and the movable part 171. When the movable part 171 moves around the fixed part 170, since the fixed part 170 is fixed to the support structure 10, the drive unit 172 can deform to generate an elastic force acting on the movable part 171. Thus, the movable part 171 can have a tendency to move.

[0127] In addition, combined Figure 4 and Figure 10The drive unit 172 can be provided on the support structure 10, and the drive unit 172 can be configured to deviate from the fixed part 170 in a direction closer to the center member 15 and abut against the movable part 171. In this case, by the drive unit 172 acting on the movable part 171 in a manner that deviates from the fixed part 170, the movable part 171 can be made to have a tendency to move around the fixed part 170, and when the movable part 171 moves around the fixed part 170, the movable part 171 can be locked and / or unlocked from the center member 15.

[0128] In some examples, the drive unit 172 can deform and recover. Specifically, the drive unit 172 can be a spring.

[0129] See Figure 10 In some examples, the end of the drive portion 172 near the movable portion 171 may be a curved end, wherein the curved surface may be smooth. That is, the end of the drive portion 172 that abuts against the movable portion 171 may be a smooth curved surface. Specifically, in some examples, the drive portion 172 may consist of a spring and a ball disposed at the end of the spring near the movable portion 171. In this case, when the drive portion 172 acts on the movable portion 171, the ball enables the movable portion 171 to rotate more smoothly relative to the drive portion 172.

[0130] In some examples, the second locking part 17 may be integrally formed, the fixing part 170 may be the part of the second locking part 17 fixed to the second support member 14 of the support structure 10, and the movable part 171 may be another part of the second locking part 17 movable to the first support member 13 of the support structure 10. In this case, the second locking part 17 can be easily manufactured.

[0131] In some examples, the second locking part 17 may not be integrally formed; the fixing part 170 and the movable part 171 may be disposed in the first support member 13. The fixing part 170 may be a component fixed to the support structure 10, such as a round shaft; the movable part 171 may be a component movable to the first support member 13. In this case, see [reference needed]. Figure 9 The combination of movable part 171 and fixed part 170 can mean that movable part 171 is movably fitted onto fixed part 170.

[0132] See Figure 8B In some examples, the combination of the movable part 171 and the fixed part 170 can mean that the movable part 171 and the fixed part 170 are combined through the connection of the drive part 172.

[0133] In some examples, the relatively stable state maintained by the movable part 171 when it moves in relation to the support structure 10 can mean that after the assembly 2 is assembled using the assembly / disassembly device 1, the force provided to the movable part 171 by the fixed part 170 or the force provided to the movable part 171 by the drive part 172 can restore the movable part 171 to its initial state. When the force is provided to the movable part 171 by the drive part 172, there should be no relative sliding between the fixed part 170 and the movable part 171 perpendicular to the plane in which the movable part 171 rotates around the fixed part 170. In this case, the assembly / disassembly device 1 can be used for multiple assemblies / disassemblies.

[0134] It should be noted that in some examples, multiple opening and closing operations using the opening and closing device 1 will cause the movable part 171 to rotate multiple times. As a result, the movable part 171 may exert additional force on the fixed part 170, which the fixed part 170 can release. In this case, multiple opening and closing operations can be performed using the opening and closing device 1.

[0135] In some examples, the center member 15 may also include a locking region 154, and the moving part 171 may act on the locking region 154 to lock and / or unlock the center member 15 by the second locking part 17. In this case, the second locking part 17 can lock and / or unlock the center member 15.

[0136] In some examples, the locking region 154 can be formed by machining multiple pre-designed tracks in the middle portion of the center member 15, and the movable part 171 can move along the multiple tracks of the locking region 154. In this case, the movable part 171 can be used to lock and / or unlock the center member 15.

[0137] Figure 11A This is a schematic diagram showing the active part 171 involved in this disclosure in a fully unlocked state in the locking area 154; Figure 11B This is a schematic diagram showing the active part 171 involved in this disclosure in a preliminary locked state in the locking area 154; Figure 11C This is a schematic diagram showing the active part 171 involved in this disclosure in a fully locked state in the locking area 154; Figure 11D This is a schematic diagram showing the active part 171 involved in this disclosure in a preliminary unlocked state in the locking area 154; Figure 11E This is a schematic diagram of a stepped structure 155 between adjacent tracks as disclosed herein.

[0138] It should be understood that, in Figures 11A to 11D In order to make the accompanying drawings clearer, some identical parts are no longer labeled repeatedly, and some parts that may cause misunderstanding have been omitted.

[0139] See Figure 11A In some examples, the locking region 154 may include a first track 1541, a second track 1542, a third track 1543, and a fourth track 1544. In some examples, the first track 1541, the second track 1542, the third track 1543, and the fourth track 1544 may be connected in sequence to form a complete loop.

[0140] See Figure 11E In some examples, the locking region 154 may have a stepped structure 155 at the connection between at least one pair of adjacent tracks. Specifically, for example, the second track 1542 may be recessed to a certain depth relative to the first track 1541 into the center member 15, thereby forming a stepped structure 155 at the connection between the first track 1541 and the second track 1542. In some examples, the movable part 171 may be in close contact with multiple tracks of the locking region 154 in the inward direction of the center member 15. In this case, after the movable part 171 passes through the stepped structure 155, it cannot reverse through the stepped structure 155 to return to the previous track. That is, under the combined action of the stepped structure 155 and the movable part 171 being in close contact with multiple tracks of the locking region 154 in the inward direction of the center member 15, the movable part 171 can move sequentially (i.e., unidirectionally) between multiple tracks.

[0141] In some examples, the locking region 154 has a stepped structure 155 at the connection between adjacent tracks. In this case, after the splitting and joining device 1 performs multiple splitting and joining operations, the tendency of the moving part 171 to move towards a vertical position may weaken or even disappear. At this time, guided by the stepped structure 155 between each pair of adjacent tracks, the moving part 171 can move in the loop formed by multiple tracks.

[0142] In some examples, the locking region 154 has a stepped structure 155 at the connection between the second track 1542 and the third track 1543, the connection between the third track 1543 and the fourth track 1544, and the connection between the fourth track 1544 and the first track 1541. In this case, the movable part 171 can move along the first track 1541 without entering the fourth track 1544 when the assembly 2 is pressed down for the first time; in addition, the movable part 171 can move along the third track 1543 without entering the second track 1542 when the assembly 2 is pressed down for the second time, and can move from the third track 1543 to the fourth track 1544.

[0143] In some examples, the track may include an inner side and an outer side. Specifically, for example, the inner side of multiple tracks may refer to the side within the range formed by the movement trajectory of the movable part 171, and the outer side of multiple tracks may refer to the side outside the range formed by the movement trajectory of the movable part 171.

[0144] See Figure 11B In some examples, the third track 1543 may have a first fixed position 1543a. In some examples, the first fixed position 1543a may be formed by bending the inner side of the third track 1543 in the insertion direction D1. In some examples, the movable part 171 may be stably stationary at the first fixed position 1543a. In this case, when the movable part 171 moves to the first fixed position 1543a in the plurality of tracks, it can be stably stationary at the first fixed position 1543a, thereby enabling the movable part 171 to lock the center member 15.

[0145] See Figure 11B In some examples, the first track 1541 may have a second fixed position 1541a. In some examples, the second fixed position 1541a may be formed by bending the outer side of the first track 1541 towards the insertion direction D1. In some examples, the movable part 171 may be stably stationary at the second fixed position 1541a. In this case, when the movable part 171 moves to the second fixed position 1541a among the multiple tracks, it can be stably stationary at the second fixed position 1541a, thereby enabling the movable part 171 to unlock the center member 15.

[0146] See Figure 11A In some examples, before the first pressing of assembly 2 onto center member 15, movable part 171 can remain stationary at the second fixed position 1541a, at which time movable part 171 is not locked to center member 15.

[0147] Combination Figure 11A , Figure 11B and Figure 11E In some examples, during the initial pressing of assembly 2 onto center member 15, fixing member 21 can push center member 15 to move in the insertion direction D1. Movable part 171, stationary at the second fixed position 1541a, can move along the first track 1541 under the action of the stepped structure 155 at the connection between the fourth track 1544 and the first track 1541. Simultaneously, under the action of the first track 1541, movable part 171 will deviate from its original vertical position and tend to move back to the vertical position. Therefore, after passing the connection between the first track 1541 and the second track 1542, movable part 171 will quickly move back to the vertical position to abut the outside of the second track 1542. In some examples, after passing the connection between the first track 1541 and the second track 1542, movable part 171 will quickly move back to the vertical position to abut the outside of the second track 1542. In this case, movable part 171 can move from the first track 1541 to the second track 1542.

[0148] In some examples, the connection point between the inner side of the fourth track 1544 and the first track 1541 can be offset from the fixing part 170 in the direction of the fourth track 1544. When the assembly 2 is pressed down on the center member 15 for the first time, during the movement of the center member 15 in the insertion direction D1, the movable part 171 can abut against the inner side of the first track 1541, but not against the inner side of the fourth track 1544. At this time, the locking region 154 may not have a stepped structure 155 at the connection between the fourth track 1544 and the first track 1541. In this case, when the assembly 2 is pressed down for the first time, the movable part 171 can move along the first track 1541 without entering the fourth track 1544, and the structure of the locking region 154 can be simplified.

[0149] Combination Figure 11B and Figure 11C In some examples, after the first downward pressure is completed and the force of the first downward pressure is removed, the elastic structure 12 can act on the central member 15 to allow the central member 15 to move in the extraction direction D2. During the movement of the central member 15 in the extraction direction D2, the movable part 171 can move from the second track 1542 to the third track 1543 and remain stationary at the first fixed position 1543a of the third track 1543. In this case, the movable part 171 can move from the second track 1542 to the third track 1543 and can lock the central member 15.

[0150] In some examples, after multiple separation and reassembly operations using the separation and reassembly device 1, the tendency of the movable part 171 to move toward a vertical position may weaken or even disappear. At this time, since there is a stepped structure 155 at the connection between the first track 1541 and the second track 1542, the movable part 171 can also move toward a vertical position under the guidance of the stepped structure 155 and the second track 1542.

[0151] In some examples, if the movable part 171 still tends to move toward a vertical position after multiple separation and retraction operations of the separation and retraction device 1, the locking region 154 may not have a stepped structure 155 at the connection between the first track 1541 and the second track 1542. In this case, the structure of the locking region 154 can be simplified.

[0152] Combination Figure 11C , Figure 11D and Figure 11EIn some examples, during the second pressing of the assembly 2 onto the center member 15, the fixing member 21 can push the center member 15 to move in the insertion direction D1. The movable part 171, which is stationary at the first fixed position 1543a, can move along the third track 1543 under the action of the stepped structure 155 at the connection between the second track 1542 and the third track 1543. At the same time, the movable part 171 will deviate from its original vertical position and has a tendency to move back to the vertical position. After the movable part 171 passes the stepped structure 155 at the connection between the third track 1543 and the fourth track 1544, the movable part 171 can move from the third track 1543 to the fourth track 1544.

[0153] In some examples, the connection point on the outer side of the second track 1542 and the third track 1543 can be offset from the fixing part 170 in the direction of the second track 1542. When the assembly 2 is pressed down on the center member 15 for the second time, during the movement of the center member 15 in the insertion direction D1, the movable part 171 can abut against the outer side of the third track 1543, but not against the outer side of the second track 1542. At this time, the locking region 154 may not have a stepped structure 155 at the connection between the second track 1542 and the third track 1543. In this case, when the assembly 2 is pressed down for the second time, the movable part 171 can move along the third track 1543 towards the fourth track 1544 without entering the second track 1542, and the structure of the locking region 154 can be simplified.

[0154] In some examples, after the movable part 171 passes the connection between the third track 1543 and the fourth track 1544, since there may be a stepped structure 155 at the connection between the third track 1543 and the fourth track 1544, and the movable part 171 has a tendency to move towards a vertical position, the movable part 171 will abut against the stepped structure 155 at the connection between the third track 1543 and the fourth track 1544, and cannot directly return from the fourth track 1544 to the third track 1543. In this case, the movable part 171 can move from the third track 1543 to the fourth track 1544, and the movable part 171 can unlock the center member 15.

[0155] Combination Figure 11A , Figure 11D and Figure 11EIn some examples, after the second downward pressure is completed and the force of the second downward pressure is removed, the elastic structure 12 can act on the central member 15 to move the central member 15 in the extraction direction D2. During the movement of the central member 15 in the extraction direction D2, the movable part 171 can move from the fourth track 1544 to the first track 1541 under the guidance of the stepped structure 155 at the connection between the third track 1543 and the fourth track 1544, and stop at the second fixed position 1541a of the first track 1541. In this case, the movable part 171 can move from the fourth track 1544 to the first track 1541, and can also return to the second fixed position 1541a.

[0156] In some examples, a variation of the locking region 154 may be formed by the middle portion of the center member 15 protruding towards the side closer to the support structure 10. In this case, the moving part 171 can lock and / or unlock the center member 15.

[0157] See Figure 9 In some examples, the movable part 171 may include at least two sets of snap-fit ​​structures. In some examples, the snap-fit ​​structures may act on variations of the locking region 154 to lock and / or unlock the center member 15. In this case, the second locking part 17 can lock and / or unlock the center member 15 through the engagement of the snap-fit ​​structures with the locking region 154, and there are at least two sets of snap-fit ​​structures to enable the opening and closing device 1 to open and close multiple times.

[0158] In some examples, the snap-fit ​​structure may include abutment 1711 and snap-fit ​​1712. See also Figure 7 In some examples, variations of the locking region 154 may include a horizontal side 1545 and a vertical side 1546. In some examples, the second locking part 17 can lock the center member 15 when the abutment 1711 abuts against the vertical side 1546 and the locking angle 1712 abuts against the horizontal side 1545. Alternatively, the second locking part 17 can unlock the center member 15 when the locking angle 1712 abuts against the vertical side 1546 or the abutment 1711 abuts against the horizontal side 1545. In this case, by changing the abutment relationship between the locking angles 1712 and 1711 and the horizontal side 1545 and vertical side 1546, the locked and unlocked states of the second locking part 17 and the center member 15 can be switched.

[0159] In some examples, the horizontal side 1545 is a variation of the locking region 154 that is perpendicular to the insertion direction D1, and the vertical side 1546 is a variation of the locking region 154 that is parallel to the insertion direction D1.

[0160] In some examples, preferably, the movable part 171 may include two sets of snap-fit ​​structures. In some examples, the two sets of snap-fit ​​structures may be symmetrical about the fixed part 170.

[0161] In some examples, the abutment 1711 and the clasp 1712 can be the same shape. In other examples, the abutment 1711 and the clasp 1712 can be different shapes.

[0162] In some examples, the abutment angle 1711 and the retaining angle 1712 can be smooth rounded corners. In this case, wear on the center member 15 when the moving part 171 rotates can be reduced.

[0164] It should be noted that, Figures 12A to 12E The second locking part 17 and locking region 154 mentioned herein refer to modified examples of the second locking part 17 and locking region 154, respectively, which provide force to the moving part 171 via the driving part 172. Furthermore, Figures 12A to 12E The embodiments shown only illustrate the state of some components of the separating and joining device 1 involved in the process of separating and joining assembly 2. To better demonstrate how the first locking part 16 locks the fixing member 21, some components (such as the elastic structure 12 and the separating member 20) and lines that might cause obstruction or misunderstanding have been omitted. Furthermore, some identical components are not repeatedly labeled in the figures. Figures 12A to 12E The fastener 21 shown is only the part where the fastener 21 is locked to the first locking part 16, and does not mean that the fastener 21 and the separating part 20 are not combined or separated during the separation process.

[0165] In some examples, the separating and merging device 1 involved in this disclosure can be configured according to... Figures 12A to 12E The sequence of assembly and disassembly of component 2. See below for reference. Figures 12A to 12E The process of assembling and disassembling component 2 is described in detail.

[0166] See Figure 12A In some examples, in the initial state, the end of the first locking part 16 away from the assembly 2 can be exposed to the first limiting part 152 in the direction of the first support 13, and the driving part 172 can deviate from the fixing part 170 in the direction of the center part 15 and abut against the locking corner 1712 of the first set of locking structures. The locking corner 1712 of the first set of locking structures can abut against the vertical side 1546.

[0167] See Figure 12B In some examples, in the initial locking state, the end of the first locking part 16 near the assembly 2 may be partially exposed outside the first limiting part 152 and abut against the third groove 211 of the fixing member 21 in the assembly 2. The end of the first locking part 16 away from the assembly 2 may contact the protrusion 101. The locking angle 1712 of the first set of locking structures may abut against the horizontal side 1545. The driving part 172 may abut against the locking angle 1712 of the first set of locking structures.

[0168] See Figure 12A and Figure 12B In some examples, the initial pressing of assembly 2 onto center member 15 can transition the disassembly / contraction device 1 from its initial state to a preliminary locked state. During this process, center member 15 can move in the insertion direction D1 under the push of fixing member 21. As center member 15 moves in the insertion direction D1, first locking part 16 can move towards the end of assembly 2 near first limiting part 152 under the action of protrusion 101 of first support member 13, abutting against the third groove 211 of fixing member 21. Simultaneously, since movable part 171 tends to rotate in the rotation direction D3 under the action of drive part 172, after center member 15 moves in the insertion direction D1 to the horizontal side 1545 below the locking angle 1712 of the first set of locking structures, the locking angle 1712 of the first set of locking structures can change from abutting the vertical side 1546 to abutting the horizontal side 1545. In this case, disassembly / contraction device 1 can be transitioned from its initial state to a preliminary locked state.

[0169] It should be noted that the initial locking state can be transient. Specifically, after the center member 15 moves in the insertion direction D1, the elastic structure 12 will be compressed, and the center member 15 will have a tendency to move in the extraction direction D2 under the action of the elastic structure 12.

[0170] See Figure 12C In some examples, when fully locked, the end of the first locking part 16 near the assembly 2 may be partially exposed outside the first limiting part 152 and abut against the third groove 211 of the fixing member 21 in the assembly 2. The end of the first locking part 16 away from the assembly 2 may contact the protrusion 101. The locking angle 1712 of the first set of locking structures may abut against the horizontal side 1545, the abutment angle 1711 of the first set of locking structures may abut against the vertical side 1546, and the driving part 172 may abut against the abutment angle 1711 of the first set of locking structures. In this case, the fixing member 21 is fixed to the separating device 1, thereby enabling the replacement of the separating member 20 in the assembly 2.

[0171] See Figure 12B and Figure 12CIn some examples, the elastic structure 12 acts on the central member 15, which can change the opening and closing device 1 from a preliminary locked state to a fully locked state. During this process, the end of the first locking part 16 near the assembly 2 can remain partially exposed outside the first limiting part 152 and abut against the third groove 211 of the fixing member 21 in the assembly 2. The end of the first locking part 16 away from the assembly 2 can remain in contact with the protrusion 101. Since the central member 15 can compress the elastic structure 12 when it moves in the insertion direction D1 during the first press, after the preliminary locking is completed, the central member 15 can move in the withdrawal direction D2 under the action of the elastic structure 12. The movable part 171 can rotate in the rotation direction D3 under the driving action of the central member 15. Since the driving part 172 can be elastic, the abutment angle 1711 of the first set of snap-fit ​​structures can compress the driving part 172 and thus slide over the driving part 172 (see Figure 12C Thus, the locking angle 1712 of the first set of locking structures can abut against the horizontal side 1545, and the abutment angle 1711 of the first set of locking structures can abut against the vertical side 1546. At the same time, the driving part 172 can abut against the abutment angle 1711 of the first set of locking structures. In this case, the opening and closing device 1 can be changed from the initial locking state to the fully locked state.

[0172] In some examples, replacing the separator 20 in assembly 2 can mean that, in the fully locked state, the separator 20 can be removed (e.g., pulled out or twisted out), allowing it to detach from assembly 2. The new separator 20 can then be combined with the retainer 21 to form assembly 2. Furthermore, during the replacement of the separator 20, the user only needs to contact the separator 20 and does not need to contact other components. This improves work efficiency, ease of use, and reduces the risk of hospital-acquired infections.

[0173] See Figure 12D In some examples, in the initial unlocked state, the end of the first locking part 16 near the assembly 2 may be partially exposed outside the first limiting part 152 and abut against the third groove 211 of the fixing member 21 in the assembly 2. The end of the first locking part 16 away from the assembly 2 may contact the protrusion 101. The abutment 1711 of the first set of snap-fit ​​structures may abut against the horizontal side 1545, and the driving part 172 may abut against the abutment 1711 of the first set of snap-fit ​​structures. In this case, the second locking part 17 can unlock the center member 15.

[0174] See Figure 12C and Figure 12DIn some examples, pressing the assembly 2 down on the center member 15 a second time can change the locking device 1 from a fully locked state to a partially unlocked state. During this process, when replacing the separating member 20, the separating member 20 and the fixing member 21 can be reassembled into the assembly 2. The center member 15 can move in the insertion direction D1 under the push of the fixing member 21. The center member 15 can move in the insertion direction D1 until the horizontal side 1545 is lower than the abutment angle 1711 of the first set of snap-fit ​​structures. The movable part 171 can rotate a certain angle in the rotation direction D3 under the action of the driving part 172, and then the abutment angle 1711 of the first set of snap-fit ​​structures can change from abutting the vertical side 1546 to abutting the horizontal side 1545 (see...). Figure 12D In this situation, the opening and closing device 1 can be changed from a fully locked state to a partially unlocked state.

[0175] It should be noted that the initial unlocking state can be transient. Specifically, after the central component 15 moves in the insertion direction D1, the elastic structure 12 will be compressed, and the central component 15 will have a tendency to move in the extraction direction D2 under the action of the elastic structure 12.

[0176] See Figure 12E In some examples, when fully unlocked, the end of the first locking part 16 near the assembly 2 may be partially exposed outside the first limiting part 152 and abut against the third groove 211 of the fixing member 21 in the assembly 2, while the end of the first locking part 16 away from the assembly 2 may disengage from the protrusion 101. The locking angle 1712 of the second set of locking structures may abut against the vertical side 1546 under the action of the driving part 172. In this case, the assembly 2 can be pulled out of the disassembly / removal device 1.

[0177] See Figure 12D and Figure 12E In some examples, the elastic structure 12 acts on the central member 15 to allow the opening and closing device 1 to change from a preliminary unlocked state to a fully unlocked state. During this process, the end of the first locking part 16 near the assembly 2 can remain partially exposed outside the first limiting part 152 and abut against the third groove 211 of the fixing member 21 in the assembly 2. The end of the first locking part 16 away from the assembly 2 can change from contacting the protrusion 101 to disengaging from contacting the protrusion 101.

[0178] Specifically, during the movement of the center member 15 in the withdrawal direction D2, the first locking part 16 can remain in the first limiting part 152 and gradually pass the protrusion 101. Since the movement of the center member 15 in the insertion direction D1 during the second pressing can compress the elastic structure 12, after the initial unlocking is completed, the center member 15 can move in the withdrawal direction D2 under the action of the elastic structure 12; at the same time, since the abutment angle 1711 of the first set of locking structures can abut the horizontal side 1545, the movable part 171 can rotate in the rotation direction D3 under the driving action of the center member 15. Since the driving part 172 can be elastic, the locking angle 1712 of the second set of locking structures can compress the driving part 172 and slide past the driving part 172 until the driving part 172 can be between the locking angle 1712 of the second set of locking structures and the abutment angle 1711 of the second set of locking structures (see Figure 12E When the drive unit 172 passes the locking angle 1712 of the second set of locking structures, the drive unit 172 can rebound and act on the locking angle 1712 of the second set of locking structures, so that the movable unit 171 can continue to rotate a certain angle in the rotation direction D3 until the locking angle 1712 of the second set of locking structures abuts the vertical side 1546 (see...). Figure 12E In this situation, the opening and closing device 1 can be changed from the initial unlocked state to the fully unlocked state.

[0179] Figure 13 This is a flowchart illustrating the method of assembling and disassembling the assembly 2 as disclosed herein.

[0180] In this embodiment, see Figure 13 The method of separating and assembling the medical assembly 2 may include: pressing the assembly 2 onto the device 1 for the first time (step S100); replacing the separator 20 in the assembly 2 (step S200); pressing the assembly 2 onto the device 1 for the second time (step S300); and removing the assembly 2 (step S400).

[0181] In some examples, in step S100, the first pressing of assembly 2 on device 1 specifically refers to placing the assembly 2 to be separated and joined on the center member 15. The first pressing of the separating member 20 causes the fixing member 21 to push the center member 15 together in the insertion direction D1. At this time, the first locking part 16 can lock the fixing member 21, so that the fixing member 21 can be locked to device 1. When the force of the first pressing is removed, the elastic structure 12 can act on the center member 15, causing the center member 15 to rebound, that is, the center member 15 can move in the withdrawal direction D2. At this time, the second locking part 17 can lock the center member 15. In this case, the first locking part 16 can lock the fixing member 21, and the second locking part 17 can lock the center member 15. Thus, a firm connection can be formed between the assembly 2 and the separating and joining device 1.

[0182] In some examples, in step S200, replacing the separator 20 in assembly 2 specifically means removing (e.g., pulling out or unscrewing) the separator 20 from assembly 2, allowing it to detach from the assembly 2 and be combined with the fixing member 21. Furthermore, during the replacement of the separator 20, the user only needs to contact the separator 20 and does not need to contact other components. This improves work efficiency, ease of use, and reduces the risk of hospital-acquired infections.

[0183] In some examples, in step S300, the second pressing of assembly 2 in device 1 specifically refers to pressing down the new separating member 20 from step S200. At this time, the new separating member 20 and the fixing member 21 can be reassembled into assembly 2. The second pressing of the new separating member 20, by pressing down assembly 2, causes the fixing member 21 to push the center member 15 together in the insertion direction D1. At this time, the second locking part 17 can unlock the center member 15. When the force of the second pressing is removed, the elastic structure 12 can act on the center member 15, causing it to spring back, allowing the center member 15 to move in the withdrawal direction D2. At this time, the first locking part 16 can unlock the fixing member 21, so that the fixing member 21 can be unlocked from device 1. In this case, the second locking part 17 can unlock the center member 15, and the first locking part 16 can unlock the fixing member 21. Therefore, assembly 2 can be separated from the separating / joining device 1.

[0184] In some examples, in step S400, removing assembly 2 specifically means that after step S300, the first locking part 16 can unlock the fixing part 21, at which point the separating part 20 can be removed to drive the fixing part 21 and thus remove assembly 2. In this case, hospital-acquired infections can be reduced.

[0185] It should be noted that during the locking process between the fixing member 21 and the device 1, the assembly 2 and the central member 15 can rebound under the action of the elastic structure 12; during the unlocking process between the fixing member 21 and the device 1, the assembly 2 and the central member 15 can rebound under the action of the elastic structure 12. In this case, the rebound action of the elastic structure 12 can enable the second locking part 17 to lock and / or unlock the central member 15.

[0186] In some examples, by separating and assembling component 2 through steps S100, S200, S300, and S400, work efficiency can be improved, ease of use can be enhanced, and hospital-acquired infections can be reduced.

[0187] While the present disclosure has been specifically described above in conjunction with the accompanying drawings and examples, it is to be understood that the foregoing description does not limit the present disclosure in any way. Those skilled in the art can make modifications and variations to the present disclosure as needed without departing from its essential spirit and scope, and all such modifications and variations shall fall within the scope of the present disclosure.
