In one embodiment, the latch portion 93 of latch 90 and link 226 can comprise contact surface 227 and 229 respectively, and contact surface 227 and 229 is in contact with one another in the rotation of latch 90.In the embodiment shown in Figure 13 A, link 226 comprises teat 281 near contact surface 229, and this teat structure also is arranged to contact with the edge 283 of latch 90, gets back to unlocked position to prevent latch 90 rotations.Friction between teat 281 and the edge 283 can help to prevent that latch 90 rotation from getting back to unlocked position.Contacting with latch 90 of link 226 to prevent that the part that latch 90 is got back to unlocked position from the latched position left-hand revolution also can have other shapes or structure.For example, in one embodiment, be bonded with each other with the contact surface 227 that prevents latch 90 left-hand revolutions and 229 one or both of on or have tooth 231 (seeing Figure 17 and Figure 18) in its vicinity alternatively.As shown in figure 18, when link 226 was promoted by cam part 208, tooth was not rejoined, thereby no longer stops latch 90 left-hand revolutions.

Figure 12 C shows breech lock 26 that is in the unlocked position and the attaching parts 212 that is in the retracted position of acquiescence.In the present embodiment, when attaching parts 212 was in retracted position, actuated components 204 also was in its default location, and wherein cam part 208 is positioned at the right side of contact component 236.Stop component 233 is in its default location with respect to actuated components 204.Stop component 233 and actuated components 204 are aimed at extended part 255, make that extended part 255 can contact with the edge 247 of stop component 233 when extended part 255 pivots along clockwise direction and descend (will describe in more detail in the back) in locking process.When breech lock 26 was in the unlocked position, contact component 236 was in lowering position and link 230 is in raised position, thereby connected spring 224 is in relaxed state.Shown in Figure 12 C, the surface 229 that edge 283 does not contact link 226 can be arranged in the edge 283 of latch portion 93.As an alternative be that when breech lock 26 was in the unlocked position, the surface 227 of latch portion 93 contacted with the surface 229 of link 226.The flange 285 that extends out from the sidewall 199 of receiving slit 200 can stop breech lock 26 further left-hand revolutions.The lower surface 287 of latch 90 can lean against on the flange 285, to prevent latch 90 further left-hand revolutions.

Figure 13 B shows breech lock 26 that mediates and the attaching parts 212 that mediates.In the present embodiment, when attaching parts 212 mediated, actuated components 204 also mediated, and wherein cam part 208 contacts with the right side edge 239 of contact component 236.When breech lock 26 mediated, the teat 281 of link 226 contacted with the edge 283 of latch portion 93.As indicated above, the friction between teat 281 and the edge 283 prevents that latch 90 from rotating to unlocked position in the counterclockwise direction.Shown in Figure 13 B, stop component 233 can construct and be arranged to contact with the extension 249 of stop component 233 by the extended part 255 that makes latch 90 and prevent latch 90 further clickwises.Specifically, the end face of the extended part 255 of latch 90 or edge 311 can lean against on the end face 313 of extension 249 of stop component 233, are further rotated along clockwise direction to prevent breech lock 26.Shown in Figure 13 B, when latch 26 mediated, link 230 and extended part 255 mediated.Shown in Figure 13 B, when link 230 mediates, with link 230 and connecting bridge 232 bonded assembly springs 224 towards midway location biased downward connecting bridge 232, contact component 236 and link 226.This structure can make the teat 281 of link 226 contact with the edge 283 of latch portion 93.When breech lock 26 mediated, releasing parts 28 can also be positioned at the midway location (not shown) between complete releasing position (seeing Figure 15) and the retracted position (seeing Figure 16).

Figure 14 shows the breech lock 26 that is in latched position and and is in the attaching parts 212 of the retracted position of acquiescence.In the present embodiment, when attaching parts 212 was in retracted position, actuated components 204 also was in its default location, and wherein cam part 208 is positioned at the right side of contact component 236.As shown in the figure, when breech lock 26 was in latched position, the part of extended part 255 can contact with the edge 247 of stop component 233.In the present embodiment, when breech lock 26 was in latched position rather than midway location, link 230 and extended part 255 were further rotated along clockwise direction.Link 230 is in lowering position, thereby spring 224 is towards the contact component 236 of decline position biased downward upper-part 225.This structure can make the edge 283 of latch portion 93 be accommodated in the groove 317 of link 226.Engaging between edge 283 and the groove 317 prevents that latch 90 left-hand revolutions are to unlocked position.

Below, the moving from the unlocked position to the latched position of breech lock 26 will be described with reference to figure 12C and embodiment shown in Figure 14.In certain embodiments, can move to latched position in order to make breech lock 26, breech lock 26 at first must be in the unlocked position shown in Figure 12 C.In this embodiment, breech lock 26 can not move to latched position from middle position.In order to make breech lock 26 move to latched position, can be inserted into breech lock connected structure 22 in the recess 92 of latch 90, rear wall 197 directions towards receiving slit 200 inwardly push away this breech lock connected structure 22 then.When the interlocking of inwardly pushing bolt closed structure 22, breech lock connected structure 22 made latch 90 rotate towards latched position along clockwise direction around pin 222, makes the contact surface 227 of latch 90 slide on the contact surface 229 of link 226.When the link 230 of latch 90 is rotated down, spring 224 elongations.Contact preventing contact component 236 between the contact surface 227 of latch 90 and the contact surface 229 of link 226 moves downward because of the bias voltage of spring 224.As shown in figure 14, before edge 283 snap fit kept in groove 317 and by groove 317, latch 90 was rotated in a clockwise direction.Edge 283 prevents that with this joint the between the groove 317 spring 224 from pulling down upper-part 225 because of connecting bridge 232, and prevents that spring 224 from upwards drawing latch 90 because of link 230.Therefore, this structure can make latch 90 rotations get back to unlocked position.As indicated above, stop component 233 structures also are arranged to prevent that latch 90 is further rotated along clockwise direction.When latch 90 rotated to latched position fully, the extended part 255 of latch 90 contacted with the left side edge 247 of stop component 233, thereby prevented that the extended part 255 of latch 90 is further rotated along clockwise direction.When breech lock 26 is in latched position because engaging between the surface of the edge 283 of latch 90 and the groove 371 of link 226, therefore can not be only by along direction F pulling and breech lock connected structure 22 is unloaded from breech lock 26.

Below, the moving from the latched position to the unlocked position of breech lock 26 will be described with reference to the embodiment shown in Figure 14, Figure 12 B and the 12C.Breech lock 26 at first can be in latched position as shown in figure 14, and breech lock connected structure 22 can be accommodated in the recess 92 of latch 90.For to breech lock 26 releases, the user can press down or start releasing parts 28, and this releasing parts makes attaching parts 212 move to extended position.As indicated above, attaching parts 212 moves to extended position makes actuated components 204 rotate along direction E.The rotation of actuated components 204 also makes contact surface 234 rotations of cam part 208 towards contact component 236.When attaching parts 212 further stretches out and actuated components 204 when being further rotated, cam part 208 is promoted along contact surface 234.In addition, stop component 233 is pushed on the part of the extended part 255 of latch 90 and overcomes the bias voltage of spring 245.Simultaneously, the contact component 236 of upper-part 225 by spring 224 biased downward at lowering position.In order to make breech lock 26 move to unlocked position, the user must overcome the friction between the surface of groove 371 of the edge 283 of friction between the contact surface 234 of power, cam part 208 and contact component 236 of power, spring 224 of power (seeing Figure 16), the spring 245 of spring 214 and latch 90 and link 226 at least and promote attaching parts 212.Shown in Figure 12 B, when attaching parts 212 further is pushed to extended position, before cam part 208 can overcome the power of spring 224 and can contact with lifting upper-part 225 with the bottom 235 of contact component 236, cam part 208 was slided on the contact surface 234 of contact component 236.Shown in Figure 12 B, by between the sidewall 189 of actuated components 204 and receiving slit 200 contact and the extended part 255 of cam part 208 and latch 90 between contact, prevent that actuated components 204 is further rotated.When upper-part 225 was raised, link 226 was raised, thereby the engaging of the edge 283 of the groove 371 of removing link 226 and latch 90.When releasing parts 28 is pressed down fully, perhaps in other words, when attaching parts 212 was in complete extended position, the user can pull container unit 12 along direction F, the feasible breech lock connected structure 22 that can take off from the recess 92 of breech lock connected structure 22 on the container unit 12.After breech lock connected structure 22 no longer was contained in the recess 92 of latch 90, spring 224 moved up latch 90 rapidly and latch 90 is rotated towards unlocked position.When latch 90 rotated to unlocked position, the contact surface 227 of latch 90 can slide on the contact surface 229 of link 226.In the rotation and no longer with after stop component 233 contacts, spring 245 can make stop component 233 move backward to its default location rapidly in the counterclockwise direction of the extended part 255 of latch 90.In certain embodiments, container unit 12 can be enough light, so spring 224 can make latch 90 rotate to unlocked position and breech lock connected structure 22 and container unit 12 are released from breech lock 26, makes breech lock 26 to move to unlocked position.Prevent latch 90 further left-hand revolutions by flange 285.Broken away from and after releasing parts 28 discharged fully at breech lock connected structure 22 with the recess 92 of latch 90, spring 214 makes attaching parts 212 move backward to retracted position rapidly and makes actuated components 204 move backward to its default location rapidly, to realize the unlocked position shown in Figure 12 C.

Below, the moving from the latched position to the midway location of breech lock 26 will be described with reference to the embodiment shown in Figure 14, Figure 13 A and Figure 13 B.As shown in figure 14 and as indicated above, breech lock 26 can be positioned at latched position at first.Breech lock connected structure 22 can remain in the recess 92 of latch 90.As indicated above, can press down releasing parts 28 breech lock 26 is moved.For example, in the present embodiment, the user must overcome the friction between the groove 371 of the edge 283 of friction between the contact surface 234 of power, cam part 208 and contact component 236 of power, spring 224 of power (seeing Figure 16), the spring 245 of spring 214 and latch 90 and link 226 at least and promote attaching parts 212.As shown in FIG. 13A, when attaching parts 212 is further pushed to extended position, before cam part 208 can overcome the power of spring 224 and can contact with lifting upper-part 225 with the bottom 235 of contact component 236, cam part 208 was slided on the contact surface 234 of contact component 236.Then, upper-part 225 can be raised, thereby makes groove 371 disengagings of edge 283 with the link 226 of latch 90.Yet, in some cases, as shown in FIG. 13A, breech lock connected structure 22 can remain in the recess 92 of latch 90, for example, container unit 12 can enough weigh, and perhaps the user can shift container unit 12 in the breech lock 26 onto with enough power, makes latch 90 remain on latched position as shown in FIG. 13A.When the user discharged releasing parts 28, spring 214 (seeing Figure 16) made attaching parts 212 move to midway location rapidly, and made actuated components 204 move to midway location rapidly.Shown in Figure 13 B, at the end face 313 of stop component 233 with before the end face 311 of extended part 255 contacts, actuated components 204 clockwise directions position rotation in the middle of it.Simultaneously, no longer with before the bottom 235 of contact component 236 contacts, cam part 208 moves along contact surface 234 in cam part 208.Shown in Figure 13 B, cam part 208 can change into the edge 239 of contact component 236 and contacting.Therefore, the upper-part 225 with contact surface 236 can drop to position in the middle of it by spring 224.Therefore, when link 226 dropped to its position, centre, the edge 283 of latch 90 engaged with the teat 281 of link 226.Breech lock connected structure 22 thereby can remain in the breech lock 26 and be in this midway location.

In the present embodiment, stop component 233 is used to prevent that actuated components 204 is further rotated along clockwise direction, makes cam part 208 keep contacting with the edge 239 of contact component 236.By contacting and the friction that produces between the edge 311 of the edge 313 of stop component 233 and extended part 255, can help to prevent actuated components 204 further clickwises.On the contrary, when breech lock 26 was in latched position, cam part 208 was positioned at the right side of contact component 236, and this can make upper-part 206 fully descend, and made the edge 283 of latch 90 be accommodated in the groove 371 of link 226.As an alternative be that when breech lock 26 mediated, upper-part 225 was in the middle of it position and latch 90 and is in position in the middle of it, makes the teat 281 of link 226 contact with the edge 283 of latch 90.

Below, the moving from middle position to unlocked position of breech lock 26 will be described with reference to the embodiment shown in figure 13B and Figure 13 A.In the present embodiment, breech lock 26 can move to unlocked position from middle position in two ways.The first, pull container unit 12 by the user along direction F, thereby pull breech lock connected structure 22 along equidirectional, can make breech lock 26 move to unlocked position from middle position.This makes breech lock connected structure 22 be pushed against on the part 315 of recess 92.When having applied enough power in pull breech lock connected structure 22 processes along direction F, edge 283 can break away from the engage position of the teat 281 of itself and link 226.Then, latch enable parts 90 upwards also rotate towards unlocked position in the counterclockwise direction by spring 224.When latch 90 rotated to unlocked position, the contact surface 227 of latch 90 can slide on the contact surface 229 of link 226.In one embodiment, contacting between the surface 229 of the surface 227 of latch 90 and link 226 can make upper-part 225 raise.As indicated above, then, spring 214 can make attaching parts 212 move backward to the retracted position of its acquiescence rapidly.

Press down releasing parts 28 by the user, also can make breech lock 26 move to unlocked position from middle position.When the user pressed down releasing parts 28, attaching parts 212 was pushed to its extended position.As shown in FIG. 13A, when attaching parts 212 is further pushed to extended position, before cam part 208 can overcome the power of spring 224 and can contact with lifting upper-part 225 with the bottom 235 of contact component 236, cam part 208 was slided on the contact surface 234 of contact component 236.When upper-part 225 is raised, can make teat 281 disengagings of edge 283 with the link 226 of latch 90.Then, the user can pull container unit 12 and breech lock connected structure 22 along direction F.After breech lock connected structure 22 no longer was accommodated in the recess 92 of latch 90, spring 224 moved up latch 90 rapidly and latch 90 is rotated to unlocked position.Break away from and after releasing parts 28 discharges fully at the recess 92 of breech lock connected structure 22 and latch 90, spring 214 makes attaching parts 212 move backward to retracted position rapidly, and make actuated components 204 move backward to its default location rapidly, thereby realize the unlocked position shown in Figure 12 C.

Breech lock 26 has other structures or set-up mode alternatively.For example, in one embodiment, the cam part 208 of actuated components 204 can construct and be arranged to be pushed against on the link 230 of latch 90, and latch 90 is rotated in the counterclockwise direction around pivot pin 222.

Figure 15 and Figure 16 illustrate in greater detail releasing parts 28 and Lock Part 30.Lock Part 30 can comprise key (not shown) and lock core 126.Key is associated with lock core 126, and same key is used for being locked in lid 18 on the container part 16 and alternatively to the lid release.In one embodiment, key can be used for manually untiing the cover lock 111 of container part 16, thereby can uncover 18 obtains the article in the container part 16.The Lock Part that Lock Part 30 is not limited to illustrate in the present embodiment.For example, can access to your password the lock or electronic lock.It is also contemplated that in certain embodiments Lock Part 30 can comprise the RFID reader, making only can be to Lock Part 30 release when identification RFID sign or transceiver.As Figure 15 and shown in Figure 16, though can use other bindiny mechanisms, lock core 126 can use spring clip 280 to be connected on the butt joint unit 14.

As Figure 15 and shown in Figure 16, Lock Part 30 is constructed and is arranged to be in and prevents that releasing parts 28 from moving and first state of latch 26, perhaps is in to allow releasing parts 28 to move and second state of latch 26.Can use key to make Lock Part 30 move to first state or second state.When Lock Part 30 was in first state, releasing parts 28 can not start, thereby latch 90 can not rotate.Figure 15 shows the detailed view of Lock Part 30 when being in first state that prevents releasing parts 28 startups.As shown in figure 15, on lock core 126, can connect interference part 238.In the present embodiment, it is Z-shaped that interference part 238 roughly is, and comprise hook-like part 240 on the end relative with the end of the connection lock core 126 of interference part 238.In the present embodiment, when lock core 126 was in first state, hook-like part 240 doggings were to the transition portion 221 of attaching parts 212.Therefore, what hook-like part 240 was arranged in platform 216 extends upward the extending upward between the transition portion 221 of part 242 and attaching parts 212, and structure and be arranged to prevent that attaching parts 212 from stretching out.In the present embodiment, when the user attempted to push releasing parts 28, the transition portion 221 of attaching parts 212 leaned against on the surface 242 of end of hook-like part 240 of interference part 236, and prevents being moved further of releasing parts 28 and attaching parts 212.Therefore, prevent that releasing parts 28 from starting.

Figure 16 shows Lock Part 30 and allows releasing parts 28 to move and detailed view during second state of latch 26 being in.In the present embodiment, use key rotational lock core 126 along clockwise direction, make interference part 238 hook-like part 240 no longer dogging on attaching parts 212.Therefore, interference part 238 can not stop attaching parts 212 to stretch out.Can start releasing parts 28 so that latch 90 rotates to unlocked position.Can use key that lock core 126 is rotated to backward and prevent that releasing parts 28 from moving and first state of latch 26.
