The linkage mechanism 3 comprises a locking component 31 and a hook component 32. The locking component 31 is arranged on the mounting base plate 2, and the hook component 32 is connected to the mounting base plate 2. The mounting base plate 2 slides relative to the base 1 along the first direction, so that the hook device 100 has a locking state and a hooking state. In the locking state, the locking component 31 is limitedly abutted against the hook component 32, and the hook component 32 moves as a whole in a direction close to the hook groove of the cargo frame 4, and the hook component 32 is partially moved to the bottom of the hook groove of the cargo frame 4. In the hooking state, the locking component 31 is separated from the hook component 32, the locking component 31 is disengaged from the hook component 32, and the hook component 32 pops up in the hook groove direction (that is, in the vertical upward direction) so that the hook component 32 hooks the cargo frame 4.

[0072] In this embodiment, the hook device 100 is applied to a warehousing system, which is applied to biological sample storage, blood station cold storage, food and drug storage, and automated warehousing and logistics centers for various products, samples, and goods such as new energy and semiconductors.

[0073] In this embodiment, the base 1 extends in a long strip shape along a first direction, and a guide rail extending along the first direction is provided on the base 1, and the mounting base 2 is slidably arranged on the guide rail. At the same time, the gripping device also includes a driving member, which is connected to the mounting base 2; the base 1 is provided with a rack, and the driving member is provided with a gear transmission connected to the rack; wherein the driving member drives the gear to move along the rack to drive the mounting base 2 to move, and together drives the linkage mechanism 3 to move relative to the base 1 along the first direction.

[0074] Meanwhile, the linkage mechanism 3 in the hooking hand device 100 includes a locking assembly 31 and a hooking hand assembly 32. The hooking hand assembly 32 is a mechanism or structure provided with a hooking hand 322. The hooking hand assembly 32 can hook the hook groove on the cargo frame 4 through the hooking hand 322 to directly hook the front of the cargo frame 4. Meanwhile, the locking assembly 31 is a fixed structure provided with a lock, such as a lock tongue 312, a lock block, a lock column and other structures elastically connected to the mounting base plate 2. In the locked state, the locking component 31 can limit the contact with the hook component 32, so that the hook component 32 can keep the position fixed before hooking the hook groove of the cargo frame 4 (that is, the hook component 32 is below the hook groove of the cargo frame 4 in the vertical direction), and when the installation base plate 2 and the linkage mechanism 3 are integrally close to the side wall of the front of the cargo frame 4, the locking component 31 can be separated from the limit contact with the hook component 32, so that the hook 322 in the hook component 32 can pop out or extend in the direction of the hook groove (that is, upward in the vertical direction) to directly extend into the hook groove on the front of the cargo frame 4. On the basis of realizing the mechanical linkage mechanism 3 controlling the hook 322 to hook the hook groove, the front of the cargo frame 4 is also hooked, effectively avoiding occupying the space around the cargo frame 4, improving the storage capacity utilization rate of the blood bank, and increasing the storage capacity of blood bags and other samples.

[0075] The hook device 100 of the present technical solution is used for hooking the cargo frame 4. The hook device 100 includes a base 1, a mounting base plate 2 and a linkage mechanism 3. The mounting base plate 2 is slidably arranged on the base 1 along a first direction. The linkage mechanism 3 includes a locking component 31 and a hook component 32. The locking component 31 is arranged on the mounting base plate 2, and the hook component 32 is elastically connected to the mounting base plate 2; wherein the mounting base plate 2 slides relative to the base 1 along the first direction so that the hook device 100 has a locking state and a hooking state. In the locking state, the locking component 31 is limitedly abutted against the hook component 32, and the hook component 32 as a whole moves closer to the cargo frame 4 The hook hand assembly 32 moves in the direction of the hook groove, and moves the hook hand part to the bottom of the hook groove of the cargo frame 4. In the hooking state, the locking component 31 is separated from the hook hand assembly 32, the locking component 31 and the hook hand assembly 32 are disengaged, and the hook hand assembly 32 pops up in the hook groove direction (that is, in the vertical upward direction) to enable the hook hand assembly 32 to hook the cargo frame 4. Through the mutual cooperation of the locking component 31 and the hook hand assembly 32 in the hook hand device 100, the hook hand 322 can directly hook the cargo frame 4 at the front side of the cargo frame 4, thereby avoiding occupying the space around the cargo frame 4, improving the storage capacity utilization of the blood bank, and increasing the storage capacity of samples such as blood bags.

[0076] In one embodiment, if Figures 1 to 8 As shown, the hook hand assembly 32 includes a first mounting seat 321, a baffle 325 and a hook hand 322. The first mounting seat 321 is slidably arranged on the mounting base plate 2 along the second direction and is elastically connected to the mounting base plate 2. The second direction is perpendicular to the first direction. The baffle 325 is elastically connected to the first mounting seat 321. The baffle 325 is provided with a contact surface 3251. The hook hand 322 is connected to the baffle 325. Part of the hook hand 322 is spaced apart from the abutment surface 3251. The hook hand 322 and the abutment surface 3251 cooperate to hook the cargo frame 4.

[0077] In this embodiment, the first mounting seat 321 is the main structure of the hook hand assembly 32. The first mounting seat 321 is a platform structure or a frame structure. The first mounting seat 321 has a rotating hole. The mounting base 2 is provided with a support column. The column body of the support column extends along the second direction to be rotatably connected with the support column through the rotating hole, and the hook hand assembly 32 can rotate relative to the support column, and the first mounting seat 321 can also slide relative to the support column through the rotating hole; the first mounting seat 321 is also elastically connected to the mounting base 2, so that when the first mounting seat 321 drives the hook hand 322 to slide along the second direction, the buffering between the hook hand assembly 32 and the mounting base 2 can be achieved through the elastic connection, and the hook hand 322 can change the position relative to the hook slot of the cargo frame 4, and the change of the device state of the hook hand 322 is achieved.

[0078] At the same time, the hook hand assembly 32 also includes a baffle 325, which is elastically connected to the first mounting seat 321. Specifically, the hook hand assembly 32 also includes a guide column 324 and an elastic member (not shown in the figure). The first mounting seat 321 is provided with a guide hole, and the axis direction of the guide hole extends along the first direction, that is, it extends in a direction perpendicular to the side wall of the cargo frame 4. One end of the guide column 324 is connected to the baffle 325, and the other end of the guide column 324 is slidably arranged in the guide hole, so that the baffle 325 can slide in a direction that is perpendicular to both the first direction and the second direction, that is, in a direction close to or away from the cargo frame 4. At the same time, the elastic member is sleeved on the outer wall of the guide column 324, and the two ends of the elastic member are respectively abutted against the baffle 325 and the first mounting seat 321.

[0079] Based on the above embodiment, further, the baffle 325 is provided with an abutment surface 3251, the abutment surface 3251 is a plane and is arranged perpendicular to the first direction, the hook hand 322 in the hook hand assembly 32 is a hook claw structure with a bent, one end of the hook hand 322 is connected to the baffle 325, the hook hand 322 has a bent end extending in the direction away from the baffle 325, and is arranged relatively spaced from the abutment surface 3251, so that a hooking space is formed between part of the hook hand 322 and the abutment surface 3251.

[0080] It can be understood that a hook groove is provided on the side of the cargo frame 4 facing the hook hand 322 device, and when the abutting surface 3251 of the baffle 325 abuts against the side wall of the cargo frame 4, the hook hand 322 can extend into the hook groove, and make part of the side wall of the cargo frame 4 located in the hooking space formed by the hook hand assembly 32, so as to realize the adaptive cooperation between the hook hand assembly 32 and the hook groove of the cargo frame 4, so as to ensure that the hook hand 322 can be quickly and accurately extended into the hook groove through the cooperation between the hook hand 322 and the baffle 325, thereby improving the accuracy of the hook hand assembly 32 in hooking the cargo frame 4, so as to improve the success rate and efficiency of the hooking of the hook hand 322 and the cargo frame 4.

[0081] It can be understood that by providing the guide column 324 and the elastic member, when the hook hand 322 abuts against the side wall of the cargo frame 4, the sliding of the guide column 324 relative to the guide hole and the compression of the elastic member provided on the outer wall of the guide column 324 can buffer the hook hand 322, thereby avoiding hard contact between the hook hand 322 and the side wall of the cargo frame 4, and making the docking fault tolerance of the hook hand 322 rotatably arranged relative to the support column of the base 1 and the hook groove of the cargo frame 4 better, reducing the angle requirement of the hook hand 322, and improving the hooking accuracy of the hook hand 322, so as to improve the hooking success rate and efficiency of the hooking of the hook hand 322 and the cargo frame 4.

[0082] In one embodiment, the base 1 is provided with a guide channel 13, and the extension direction of the guide channel 13 is set at an angle with the first direction and the second direction; the hook hand assembly 32 also includes a guide wheel 323, the guide wheel 323 is connected to the first mounting seat 321, and the guide wheel 323 rolls along the guide channel 13 to put the hook hand device 100 in a locked state.

[0083] It can be understood that the guide channel 13 is arranged on the base 1, and the opening of the guide channel 13 is arranged on the side surface of the mounting base 2 sliding relative to the base 1, and is arranged toward the hook hand assembly 32. At the same time, the extension direction of the guide channel 13 is set at an angle with the first direction and the second direction, so that the guide channel 13 is set at an angle. When the mounting base 2 drives the linkage mechanism 3 to move relative to the base 1, the guide wheel 323 provided on the hook hand assembly 32 can extend into the guide channel 13, and in the process of moving in a straight line relative to the base 1, the guide wheel 323 can also roll in the guide channel 13 along the extension direction of the guide channel 13.

[0084] Furthermore, when the guide wheel 323 rolls in the guide channel 13, influenced by the extension direction of the guide channel 13, the guide wheel 323 drives the first mounting seat 321 to move toward the mounting base plate 2, and the first mounting seat 321 also drives the hook hand 322 to move toward the base 1, so that the hook hand 322 can be moved toward the hook groove of the cargo frame 4 while being located below the hook groove, and the hook hand device 100 is in a locked state, which also facilitates the subsequent release of the hook hand 322 through the locking assembly to hook the hook groove.

[0085] In one embodiment, if Figure 1 and Figure 2 As shown, the base 1 is provided with a guide groove 12 and a guide plate 11 arranged opposite to the groove opening of the guide groove 12, and the guide plate 11 and the groove wall of the guide groove 12 enclose a guide channel 13; the guide wheel 323 extends into the guide groove 12 and rolls along the guide plate 11 to put the hook device 100 in a locked state.

[0086] In this embodiment, the guide plate 11 is a plate-like structure, and the plate surface of the guide plate 11 is inclined on the base 1, so that the plate surface of the guide plate 11 is set at an angle with the installation plane, and the plate surface of the guide plate 11 is also set perpendicular to the second direction, and the distance between the guide plate 11 and the installation plane is gradually reduced from the adjacent linkage mechanism 3 to the farthest away from the linkage mechanism 3. Furthermore, a guide groove 12 is provided on the installation plane, and the groove body of the guide groove 12 extends along the first direction or at an angle to the first direction, and the guide plate 11 and the guide groove 12 are spaced apart from each other to jointly enclose a guide channel 13.

[0087] The guide wheel 323 is used to roll along the guide plate 11, and the guide groove 12 is used to avoid the guide wheel 323. The guide wheel 323 rolls along the guide plate 11, and in the process of rolling, since the guide plate 11 is set at an angle relative to the installation plane, the guide wheel 323 rolls on the guide plate 11, and the guide wheel 323 drives the hook hand assembly 32 to move in a direction perpendicular to the installation plane, that is, in the second direction. At this time, during the movement of the hook hand assembly 32, the locking assembly 31 can be triggered. The locking assembly 31 is provided with a resiliently connected lock tongue 312 or lock column. The lock tongue 312 or lock column is popped out to lock the hook hand assembly 32 to keep the position of the hook hand assembly 32 fixed relative to the base 1. At this time, the hook hand device 100 is in a locked state.

[0088] It can be understood that by providing a guide plate 11 on the base 1 and providing a guide wheel 323 on the hook hand assembly 32 corresponding to the guide plate 11, the hook hand assembly 32 can be automatically locked during the movement of the linkage mechanism 3 relative to the base 1, so as to keep the position of the hook hand assembly 32 fixed relative to the base 1 before entering the hooking state, that is, even if the hook hand 322 is under the hook groove of the cargo frame 4, in the hooking state, the locking assembly 31 is separated from the hook hand assembly 32, and the locking assembly 31 and the hook hand assembly 32 are disengaged from the abutment, and the hook hand assembly 32 pops up in the hook groove direction (that is, in the vertical upward direction), so that the hook hand assembly 32 hooks the cargo frame 4, thereby effectively improving the hooking efficiency.

[0089] Based on the above embodiment, further, after the hook hand 322 hooks the cargo frame 4, the installation base plate 2 drives the hook hand assembly 32 to return to the starting position, and the guide wheel 323 rolls from the side surface of the guide plate 11 facing away from the guide groove 12, and maintains the hooking state of the hook hand 322 and the cargo frame 4. When unloading the cargo frame 4, the installation base plate 2 drives the hook hand assembly 32 to move forward, the guide wheel 323 extends into the guide channel 13 and rolls along the surface of the guide plate 11 facing the guide groove 12, and drives the first mounting seat 321 and the hook hand 322 to move toward the installation base plate 2, so that the locking assembly 31 locks the hook hand assembly 32, the hook hand device 100 is in a locked state, and the hook hand 322 is separated from the hook groove of the cargo frame 4, the installation base plate 2 drives the hook hand assembly 32 to retreat, and the cargo frame 4 remains in the target position.

[0090] In one embodiment, if Figures 3 to 7 , Fig. 9 as well as Fig.10As shown, the locking assembly 31 includes a vertical plate 311, a locking tongue 312 and a paddle 313. The vertical plate 311 is arranged on the mounting base plate 2, the locking tongue 312 is elastically connected to the vertical plate 311, and the paddle 313 is slidably arranged on the vertical plate 311 along a second direction perpendicular to the first direction and is elastically connected to the vertical plate 311; in the locked state, the locking tongue 312 is limitedly abutted against the hook hand assembly 32; in the hooking state, the paddle 313 pushes the locking tongue 312 to move and causes the locking tongue 312 to separate from the hook hand assembly 32.

[0091] In this embodiment, the vertical plate 311 is a structural support component of the locking assembly 31. The vertical plate 311 is a plate-like structure, and of course it can also be a frame structure. The vertical plate 311 is arranged on the mounting base plate 2, and the plate surface of the vertical plate 311 extends along the second direction and is arranged perpendicular to the plane where the mounting plane is located. At the same time, the locking tongue 312 is elastically connected to the vertical plate 311. At the same time, the locking tongue 312 is rotatably connected to the vertical plate 311. The locking assembly 31 includes a first elastic member 314, which is arranged on the vertical plate 311, and one end of the first elastic member 314 is elastically abutted or elastically connected to the vertical plate 311, and the other end of the first elastic member 314 is elastically abutted or elastically connected to the locking tongue 312, so that the locking tongue 312 is pushed against the locking tongue 312 by the first elastic member 314, so that the locking tongue 312 can rotate around the axis extending along the first direction, and the locking tongue 312 abuts against the first mounting seat 321 or is separated from the abutment with the first mounting seat 321.

[0092] At the same time, the locking assembly 31 also includes a paddle 313, which is movably arranged on the vertical plate 311. When the paddle 313 moves relative to the vertical plate 311, the paddle 313 can abut against the lock tongue 312 and drive the lock tongue 312 to rotate relative to the vertical plate 311. At this time, the lock tongue 312 compresses the first elastic member 314, and the paddle 313 continues to abut against the lock tongue 312, so that the lock tongue 312 is disengaged from the abutment with the first mounting seat 321, and the hook hand 322 in the hook hand assembly 32 is ejected or extended upward, that is, in the direction of the hook groove, and enters the hook groove of the cargo frame 4 to achieve hooking. At this time, the hook hand device 100 is in a hooking state.

[0093] It can be understood that by driving or driving the paddle 313 to move, the state of the lock tongue 312 can be changed, thereby changing the relationship between the lock tongue 312 and the hook hand assembly 32, wherein the paddle 313 can move relative to the vertical plate 311 along the second direction, and during the movement, it can drive the lock tongue 312 to rotate relative to the vertical plate 311, and compress the first elastic member 314, so that the lock tongue 312 is disconnected from the first mounting seat 321, and the hook hand 322 in the hook hand assembly 32 is popped out or extended to enter the hook groove of the cargo frame 4 for hooking.

[0094] At the same time, the locking assembly 31 also includes a second elastic member 315, one end of the second elastic member 315 is connected to the vertical plate 311, and the other end of the second elastic member 315 is connected to the paddle 313. When the paddle 313 moves relative to the vertical plate 311, the paddle 313 can gradually abut against the lock tongue 312. At this time, the second elastic member 315 is stretched by force. When the paddle 313 pushes the lock tongue 312 to move, the lock tongue 312 gradually breaks away from the abutment with the first mounting seat 321 in the hook hand assembly 32. When the lock tongue 312 is completely separated from the first mounting seat 321, After the first mounting seat 321 abuts against 21, the first mounting seat 321 drives the hook hand 322 to pop out in the upward direction (that is, toward the hook groove) under the action of the elastic force of the elastic connection with the mounting base plate 2, and the hook hand 322 simultaneously extends into the hook groove to achieve hooking. By providing the second elastic member 315, the movable abutment process between the paddle 313 and the lock tongue 312 can be made smoother, so that the lock tongue 312 gradually presses against the first elastic member 314, and the hook hand 322 hooks the hook groove, and at the same time, it is convenient to reset the paddle 313, so as to achieve free switching between the hooking state and the locking state.

[0095] In one embodiment, if Figures 9 to 11 As shown, the locking tongue 312 includes a connecting portion 312a, a locking portion 3121 and a linkage portion 3122. The connecting portion 312a is rotatably arranged on the vertical plate 311 with the second direction as the axis. The locking portion 3121 is arranged on the side of the connecting portion 312a facing the hook hand assembly 32. The locking portion 3121 is elastically connected to the vertical plate 311, and the linkage portion 3122 is connected to the connecting portion 312a. In the locked state, the locking portion 3121 abuts against the hook hand assembly 32. In the hooking state, the paddle 313 pushes against the linkage portion 3122 to rotate the connecting portion 312a relative to the vertical plate 311 and disengage the locking portion 3121 from the hook hand assembly 32.

[0096] It can be understood that the connecting portion 312a is rotatably arranged on the vertical plate 311, and the connecting portion 312a rotates relative to the vertical plate 311 around an axis extending along the first direction, the locking portion 3121 and the linkage portion 3122 are connected to the connecting portion 312a, and the locking portion 3121 is arranged on a side of the connecting portion 312a facing the first mounting seat 321 in the hook hand assembly 32, and the linkage portion 3122 is arranged on a side of the connecting portion 312a adjacent to the paddle 313, and the locking portion 3121 is used for the lock tongue 312 to lock the locking tongue 312. The structure abutting the first mounting seat 321 can be a table or plate structure with a plane, and the locking portion 3121 is away from the rotational connection with the vertical plate 311, and elastically abuts against the first elastic member 314. In the locked state, the first elastic member 314 maintains the elastic push on the locking portion 3121, and makes the locking portion 3121 abut against the first mounting seat 321 of the hook hand assembly 32. At this time, under the limited abutment of the locking portion 3121, the hook hand 322 is below the hook groove of the cargo frame 4.

[0097] At the same time, the locking tongue 312 also includes a linkage portion 3122 connected to the connecting portion 312a. The linkage portion 3122 and the connecting portion 312a, as well as the locking portion 3121 and the connecting portion 312a, can be integrally formed, or can be separately connected, such as welding or bolting, etc. The linkage portion 3122 has a plane, a curved surface, or an inclined surface that abuts against the paddle 313. Before the hooking state, the paddle 313 gradually pushes against the linkage portion 3122, and the linkage portion 3122 drives the connecting portion 312a and the locking portion 3121 to rotate relative to the vertical plate 311. During the rotation, the locking portion 3121 compresses the first elastic member 314, and causes the locking portion 3121 to disengage from the first mounting seat 321, and causes the hook hand device 100 to enter the hooking state, and the hook hand 322 bounces upward or extends into the hook groove to hook the cargo frame 4.

[0098] It can be understood that by setting the lock tongue 312 as a two-part structure of a locking part 3121 and a linkage part 3122, the linkage part 3122 can be pushed and toggled by the paddle 313 to achieve the disengagement of the locking part 3121 from the first mounting seat 321 and the hook hand assembly 32, thereby enabling the hook hand device 100 to enter a hooking state, that is, the change of the state of the hook hand 322 of the hook hand assembly 32 can be achieved only through the mechanical linkage mechanism 3, thereby achieving the hooking of the front of the cargo frame 4, effectively avoiding occupying the space around the cargo frame 4, improving the storage capacity utilization of the blood bank, and increasing the storage capacity of samples such as blood bags.

[0099] In one embodiment, if Fig.10 and Fig.11 As shown, a first inclined surface 3123 is provided on the side of the linkage portion 3122 facing the paddle 313, and a second inclined surface 3131 is provided on the side of the paddle 313 facing the linkage portion 3122; the paddle 313 moves along the second direction, and the second inclined surface 3131 pushes against the first inclined surface 3123 to drive the connecting portion 312a to rotate, and the locking portion 3121 disengages from the hook hand assembly 32 to enter a hooking state.

[0100] In this embodiment, the first bevel 3123 and the second bevel 3131 are arranged relatively parallel, that is, the first bevel 3123 is arranged toward the paddle 313, and the second bevel 3131 is arranged toward the linkage portion 3122, and the first bevel 3123 and the second bevel 3131 are arranged at an angle to the plane where the installation plane is located.

[0101] It can be understood that, during the movement of the paddle 313, the second inclined surface 3131 gradually abuts against the first inclined surface 3123, and through the abutment between the second inclined surface 3131 and the first inclined surface 3123, the linkage portion 3122 drives the connecting portion 312a to rotate relative to the vertical plate 311, and the locking portion 3121 compresses the first elastic member 314. At this time, the abutment area between the second inclined surface 3131 and the first inclined surface 3123 gradually decreases until the second inclined surface 3131 and the first inclined surface 3123 are separated from the abutment, and the locking portion 3121 is also separated from the abutment with the first mounting seat 321. The hook hand 322 is popped out or extended in the direction of the hook groove so that the hook hand device 100 enters the hooking state. By setting the first inclined surface 3123 and the second inclined surface 3131, the rotational movement of the lock tongue 312 can be achieved through the linear movement of the paddle 313, so that the locking part 3121 is separated from the first mounting seat 321. The state of the hook hand 322 of the hook hand assembly 32 can be changed through the mechanical linkage mechanism 3, so that the front of the cargo frame 4 can be hooked, which effectively avoids occupying the space around the cargo frame 4, improves the storage capacity utilization rate of the blood bank, and increases the storage capacity of samples such as blood bags.

[0102] In one embodiment, if Figures 1 to 7 , Fig.12 as well as Fig.13 As shown, the linkage mechanism 3 also includes a detection component 33, which is connected to the hook hand component 32 and the locking component 31; the detection component 33 and the hook hand component 32 are slidably arranged on the mounting base plate 2 along a second direction perpendicular to the first direction, and the detection component 33 abuts against the cargo frame 4 to disengage the locking component 31 from the hook hand component 32.

[0103] In this embodiment, the detection component 33 is movably connected to the first mounting seat 321 in the hook hand component 32, and is movably connected to the paddle 313 in the locking component 31. The detection component 33 and the hook hand component 32 are both slidably arranged on the mounting base plate 2 along the second direction. A partial structure of the detection component 33 protrudes the hook hand 322 along the first direction, so as to first abut and detect the side wall of the cargo frame 4.

[0104] It can be understood that the detection component 33 is an auxiliary structure of the hook hand component 32 in the hook hand device 100, which is used to first abut the cargo frame 4. When the protruding hook hand 322 of the detection component 33 abuts against the cargo frame 4, it will slide relative to the mounting base 2 along the second direction. During the sliding process, the detection component 33 can drive the paddle 313 to slide along the second direction, thereby realizing the linear movement of the paddle 313. Furthermore, the locking tongue 312 can be rotated through the linkage abutment between the paddle 313 and the linkage part 3122, so that the locking part 3121 of the locking tongue 312 is disengaged from the abutment with the first mounting seat 321, so that the hook hand device 100 enters the hooking state, and the hook hand 322 hooks the cargo frame 4.

[0105] It can be understood that when the hook device 100 abuts against the cargo frame 4 at the front, the detection component 33 is set to abut the side wall of the front of the cargo frame 4 first, which can drive the movement of the paddle 313 in the locking component 31, so that the rotational movement of the lock tongue 312 is realized through the linear movement of the paddle 313, so that the lock tongue 312 is disengaged from the abutment with the first mounting seat 321, and the hook hand 322 is popped out or extended to directly extend into the hook groove on the front of the cargo frame 4. On the basis of realizing the mechanical linkage mechanism 3 controlling the hook hand 322 to hook the hook groove, the hooking of the front of the cargo frame 4 is also realized, which effectively avoids occupying the space around the cargo frame 4, improves the storage capacity utilization rate of the blood bank, and increases the storage capacity of samples such as blood bags.

[0106] In one embodiment, if Figures 1 to 7 , Fig.12 as well as Fig.13 As shown, the detection assembly includes a detection body 331 and a guide structure 332. The detection body 331 is slidably arranged on the mounting base plate 2 and connected to the hook hand assembly 32. The guide structure 332 is rotatably connected to the detection body 331. In the hooking state, the guide structure 332 abuts against the cargo frame 4.

[0107] In this embodiment, the detection body 331 is the main structure of the detection assembly 33. The detection body 331 can be a frame structure, a connecting rod structure, or a support platform or support frame structure, which is not limited here. The detection body 331 is slidably arranged on the mounting base plate 2 along the second direction, and the detection body 331 is connected to the hook hand assembly 32, so that when the detection body 331 rotates, it can drive the hook hand assembly 32 and the hook hand 322 arranged on the hook hand assembly 32 to rotate together. The guide structure 332 is connected to the detection body 331, and the detection body 331 forms a detection end at one end or one side away from the mounting base plate 2, and the guide structure 332 is arranged at the detection end.

[0108] It can be understood that the detection body 331 is used for sliding connection to the mounting base plate 2 on the one hand, and for installing and supporting the guide structure 332 on the other hand. The guide structure 332 is arranged at the end or edge of the protruding hook hand 322 of the detection body 331. The guide structure 332 is used to first abut the side wall of the cargo frame 4. The guide structure 332 can be a plate structure, a rod (bar) structure, and a roller structure, etc. By setting the guide structure 332, it can first abut the side wall of the cargo frame 4, and as the linkage mechanism 3 and the mounting base plate 2 continuously approach the front of the cargo frame 4 along the first direction, the guide structure 332 also continuously abuts against the side wall of the front of the cargo frame 4, and in the process of the abutment of the guide structure 332, the detection body 331 can slide relative to the mounting base plate 2 along the second direction, so as to drive the paddle 313 to move along the second direction, and make the paddle 313 push the lock tongue 312 to rotate, so as to realize the hooking of the hook groove on the front of the cargo frame 4 by the hook hand 322.

[0109] In another embodiment of the present invention, the detection assembly 33 and the hook hand assembly 32 can be coaxially rotatably arranged relative to the base 1 with the straight line in the second direction as the axis. Specifically, the detection body 331 in the detection assembly 33 is rotatably arranged on the mounting base plate 2. At the same time, the detection body 331 is connected to the first mounting seat 321 in the hook hand assembly 32. When the partial guide structure 332 of the detection assembly 33 first abuts against the side wall of the cargo frame 4, due to the uneven force on the guide structure 332 and the side wall of the cargo frame 4, the detection body 331 will be driven to rotate relative to the mounting base plate 2, and the entire guide structure 332 will abut against the side wall of the cargo frame 4. In addition, the detection body 331 will drive the first mounting seat 321 to rotate during the rotation process, thereby realizing the rotation of the hook hand 322, so as to correct the position of the hook hand assembly 32 and the hook hand 322 provided on the hook hand assembly 32, and enable the hook hand 322 to align with the hook groove on the cargo frame 4.

[0110] At the same time, it is preferred that the guide structure 332 is arranged on both sides of the rotation direction of the hook hand 322 relative to the installation base plate 2 (hereinafter referred to as the two sides of the hook hand 322), so that when the guide structure 332 of any part of the two sides of the hook hand 322 abuts against the side wall of the cargo frame 4, it can drive the detection component 33 and the hook hand component 32 to rotate, thereby driving the hook hand 322 to rotate so that the hook hand 322 is aligned with the hook groove on the cargo frame 4, achieving precise docking and hooking, and effectively improving the success rate and efficiency of hooking.

[0111] In another embodiment of the present invention, Fig.12 and Fig.13 As shown, the detection assembly 33 also includes two linkage rods 333, and the two linkage rods 333 are connected to the detection body 331; the first mounting seat 321 is provided with two mounting holes corresponding to the linkage rods 333, and the two mounting holes are symmetrically arranged about the hook hand 322, and each linkage rod 333 extends into a mounting hole so that the detection body 331 can be movably connected to the first mounting seat 321.

[0112] In this embodiment, one end of the linkage rod 333 is connected to the detection body 331, and the other end of the linkage rod 333 extends into the mounting hole of the first mounting seat 321, and the rod body of the linkage rod 333 extends along the second direction, so that when the guide structure 332 in the detection assembly 33 abuts against the side wall of the cargo frame 4 and drives the detection body 331 to rotate relative to the mounting base 2 around the second direction, the linkage rod 333 can be used to drive the first mounting seat 321 to rotate together, thereby driving the hook hand 322 connected to the first mounting seat 321 to rotate together, realizing the linkage between the guide structure 332 and the hook hand 322, so as to improve the response speed between the guide structure 332 and the hook hand 322, so that the hook hand 322 can quickly correspond to the hook groove of the cargo frame 4, and improve the hooking accuracy of the hook hand 322.

[0113] In one embodiment, if Figures 1 to 7 , Fig.12 as well as Fig.13 As shown, the guide structure 332 includes two detection rollers 3321 , which are movably disposed on the detection body 331 , and the two detection rollers 3321 are located on both sides of the hook hand assembly 32 .

[0114] In this embodiment, a rotating shaft is provided at one end or one side of the detection body 331 facing the cargo frame 4, and two detection rollers 3321 are rotatably provided on the rotating shaft. The axis of the rotating shaft extends in a direction that is perpendicular to both the first direction and the second direction, so that the detection roller 3321 can rotate around the axis of the rotating shaft, and the two detection rollers 3321 can be provided on both sides of the hook hand 322 along the axial direction of the rotating shaft.

[0115] It can be understood that the two detection rollers 3321 located on both sides of the hook hand 322 along the axial direction of the rotating shaft, when one of the detection rollers 3321 abuts against the side wall of the cargo frame 4, the guide structure 332 is subjected to uneven force, and the detection body 331 will rotate around the second direction relative to the mounting base plate 2. The detection body 331 drives the connected hook hand assembly 32 to rotate coaxially around the second direction, thereby changing the position of the hook hand 322 to correct the position of the hook hand 322 relative to the hook slot of the cargo frame 4, so that the hook hand 322 is aligned with the hook slot on the cargo frame 4, so as to achieve rapid positioning of the hook hand 322 and improve the accuracy of hooking.

[0116] At the same time, two detection rollers 3321 are arranged on both sides of the hook hand 322 along the axis of the rotating shaft. By setting the detection rollers 3321, when the guide structure 332 abuts against the cargo frame 4, the rolling of the detection rollers 3321 relative to the side walls of the cargo frame 4 can reduce the hard contact between the guide structure 332 and the cargo frame 4 caused by uneven force on the guide structure 332, and gradually transition to when both detection rollers 3321 abut against the side walls of the cargo frame 4, so that the entire guide structure 332 abuts against the side walls of the cargo frame 4, thereby improving the overall hooking success rate and efficiency.

[0117] In one embodiment, if Figures 3 to 7 , Fig.12 as well as Fig.13 As shown, the detection body 331 includes a second mounting seat 3311 and a connecting arm assembly 3312 . The second mounting seat 3311 is slidably disposed on the base 1 . The connecting arm assembly 3312 is rotatably connected to the second mounting seat 3311 and extends in a direction away from the base 1 to connect to the guide structure 332 .

[0118] In this embodiment, the second mounting seat 3311 is a structural support component of the detection body 331 and the detection assembly 33. The second mounting seat 3311 can be a seat body, a platform body or a frame structure. The second mounting seat 3311 is arranged on the mounting base plate 2 and can slide relative to the mounting base plate 2 along the second direction. For example, a rotating hole is provided on the second mounting seat 3311, and a rotating shaft or a rotating column is provided on the mounting base plate 2 corresponding to the rotating hole. The rotating shaft extends along the second direction and is rotated in the rotating hole by the rotating shaft to realize the rotation and sliding of the second mounting seat 3311 relative to the mounting base plate 2. At the same time, the second mounting seat 3311 is connected to the first mounting seat 321 in the hook hand assembly 32 through the above-mentioned linkage rod 333, so that the rotation of the first mounting seat 321 is driven by the rotation of the second mounting seat 3311.

[0119] In addition, the second mounting seat 3311 is connected to the paddle 313. For example, a connecting groove 3111 is opened on the vertical plate 311, and the second mounting seat 3311 is provided with a transmission rod 3313. The transmission rod 3313 passes through the connecting groove 3111 and is connected to the paddle 313. When the second mounting seat 3311 slides relative to the support column 22 along the second direction, the second mounting seat 3311 can drive the paddle 313 to move through the transmission rod 3313, and make the paddle 313 drive the lock tongue 312 to rotate, so as to realize the separation of the lock tongue 312 from the first mounting seat 321, and make the hook hand 322 directly hook the hook groove on the front side of the cargo frame 4.

[0120] In this embodiment, the connecting arm assembly 3312 is used to connect the second mounting seat 3311 and the guide structure 332. The connecting arm assembly 3312 is a support arm structure, which extends from the second mounting seat 3311 in a direction away from the second mounting seat 3311, that is, in the direction of the cargo frame 4, so as to connect the guide structure 332 at one end of the connecting arm assembly 3312 away from the second mounting seat 3311, so that the guide structure 332 can protrude a certain area of ​​the hook hand 322, and can make the detection roller 3321 of the guide structure 332 first abut against the side wall of the cargo frame 4, and further make the hook hand 322 enter the hook groove, that is, the connecting arm assembly 3312 can adjust the position of the guide structure 332 and the distance of the protruding hook hand 322, and the above-mentioned rotating shaft or card hole and other structures are provided on the connecting arm assembly 3312 for installing the detection roller 3321 or the detection rod or the detection plate and other structures.

[0121] In another embodiment of the present invention, Fig.12 and Fig.13As shown, the connecting arm assembly 3312 includes a first connecting arm 3314, a connecting rod 3315 and two second connecting arms 3316. The first connecting arm 3314 is elastically connected to the second mounting seat 3311, and the first connecting arm 3314 can rotate relative to the second mounting seat 3311. The connecting rod 3315 is connected to the second mounting seat 3311. The rod body of the connecting rod 3315 is extended along a direction perpendicular to the rotation direction of the second mounting seat 3311 relative to the base 1. Each second connecting arm 3316 is connected to one end of the connecting rod 3315. The two second connecting arms 3316 are symmetrically arranged on both sides of the hook hand 322, and each detection roller 3321 is arranged on a second connecting arm 3316.

[0122] In this embodiment, the first connecting arm 3314 is elastically connected to the second mounting seat 3311, such as being elastically connected to the second mounting seat 3311 through a torsion spring or a compression spring, and can rotate relative to the second mounting seat 3311. The other end of the first connecting arm 3314 extends in a direction away from the second mounting seat 3311 and is connected to the connecting rod 3315. The connecting rod 3315 is a rod-shaped structure, and the rod body of the connecting rod 3315 is extended in a direction perpendicular to the first direction and the second direction. A second connecting arm 3316 is respectively connected at both ends of the connecting rod 3315 along the second direction, so that the two second connecting arms 3316 are symmetrically arranged on both sides of the hook hand 322.

[0123] It can be understood that the first connecting arm 3314 is used to connect the second mounting seat 3311 and the connecting rod 3315. The first connecting arm 3314 is a bent arm structure so that one end of the first connecting arm 3314 is elastically connected to the second mounting seat 3311, and the other end of the first connecting arm 3314 is connected to the connecting rod 3315. If a mounting hole is provided on the first connecting arm 3314, the connecting rod 3315 extends into the mounting hole to realize the connection between the connecting rod 3315 and the first connecting arm 3314. The second connecting arm 3316 is also a bent arm structure, one end of which is connected to the end of the connecting rod 3315, and the other end is connected to a guide structure 332, such as a detection roller 3321 or a detection rod.

[0124] It can be understood that by connecting the two second connecting arms 3316 through the connecting rod 3315 and setting up the two second connecting arms 3316, the connecting arm assembly 3312 of the guide structure 332 can form an avoidance space to avoid the hook hand 322 located between the two second connecting arms 3316, so that when the second connecting arms 3316 on both sides contact the side wall of the cargo frame 4 with one of the guide structures 332, the accurate positioning of the hook hand 322 and the hook groove on the cargo frame 4 is guaranteed.
