However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0032] On the one hand, the utility model provides a limiting mechanism 100 for limiting the relative position between two objects, and in particular for limiting the movement of two objects that can move relative to each other in a predetermined direction. Specifically, in one embodiment, please refer to Figures 1 to 3 The limiting mechanism 100 includes a fixing seat 1, a driving member 20, a limiting member 4 and a transmission assembly 3. The fixing seat 1 is fixedly arranged, and the driving member 20 is arranged on the fixing seat 1 for providing driving force.

[0033] The limiting member 4 is movably arranged on the fixing seat 1 , and the limiting member 4 has a limiting position for limiting the relative movement between two objects and a disengaging position for releasing the limitation relative to the fixing seat 1 .

[0034] It should be noted that when the limiter 4 is in the limiting position, it can block the path of relative movement of the two objects, so that the two objects cannot move relative to each other in the predetermined direction. When the limiter 4 is in the disengaging position, the two objects can move relative to each other in the predetermined direction.

[0035] The transmission assembly 3 is connected between the driving member 20 and the limiting member 4. The driving member 20 can transmit the driving force to the limiting member 4 through the transmission assembly 3, thereby driving the limiting member 4 to change between the limiting position and the disengaging position.

[0036] By setting the limiting mechanism 100, the limiting mechanism 100 can be connected to any one of the two objects that can move relative to each other in a predetermined direction through the fixing seat 1, and then the driving force of the driving member 20 is transmitted to the limiting member 4 through the transmission assembly 3, and the limiting member 4 can be driven to the limiting position. At this time, the limiting member 4 can block the relative movement path of the two objects, limit the relative movement of the two objects, and realize the limiting function of the two objects. The limiting mechanism 100 of the present application limits the two objects by driving the movement of the limiting member 4, and has a simple structure, convenient production and processing, and convenient assembly.

[0037] In one embodiment, see Figures 1 to 3 The driving member 20 is preferably a driving motor, and the driving motor has a rotatable output shaft, and the output shaft rotates when the driving motor is working. The transmission assembly 3 includes a swinging member 31, and the swinging member 31 has a connecting portion 311 and a swinging portion 312. The connecting portion 311 and the swinging portion 312 are connected together, and preferably the connecting portion 311 and the swinging portion 312 are integrally formed. The connecting portion 311 is connected to the output shaft of the driving motor. When the driving motor is working, the output shaft outputs a rotational force, and the rotational force can drive the connecting portion 311 to rotate, and then can drive the swinging portion 312 to swing at the same time.

[0038] It should be noted that the swinging part 312 is rotatably connected to the limit member 4, the rotating shaft between the rotating part and the limit member 4 is parallel to the output axis of the driving member 20, the swinging part 31 and the limit member 4 can rotate around the axis in the first direction, and the connection position between the swinging part 312 and the limit member 4 can also move relative to each other along a predetermined direction.

[0039] It is worth mentioning that the first direction is Figure 1 The predetermined direction is parallel to the center X-axis, and the predetermined direction is the direction between the rotating axis of the driving member 20 and the rotating axis of the limiting member 4 relative to the swinging part 312. In a preferred embodiment, the predetermined direction is the direction extending from the rotating axis of the driving member 20 toward the rotating axis between the swinging member 31 and the limiting member 4.

[0040] When the driving member 20 drives the swinging part 312 to swing, it can drive the limiting member 4 to have two movements relative to the swinging part 312. One is the rotation of the limiting member 4 relative to the swinging part 312, and the other is the movement of the limiting member 4 relative to the swinging part 312 along a predetermined direction. These two relative movements between the swinging part 312 and the limiting member 4 can realize the transformation of the limiting member 4 between the limiting position and the disengagement position.

[0041] By setting the connecting part 311 and the swinging part 312, on the one hand, a connection can be established between the limit member 4 and the driving member 20, so that the limit member 4 can be indirectly connected to the driving member 20, so that the driving force of the driving member 20 can be transmitted to the limit member 4. On the other hand, by setting the transmission assembly 3, it is also possible to facilitate the conversion of the driving mode of the driving member 20, that is, the output shaft of the driving member 20 outputs rotation, and by driving the connecting part 311 and the swinging part 312 to rotate, and by cooperating the swinging part 312 and the limit member 4, the rotation of the output shaft can be converted into the movement of the limit member 4 between the limiting position and the disengagement position.

[0042] It should be noted that, in the present application, the path of the limiting member 4 from the limiting position to the disengaging position is preferably set as a straight line and is set along the second direction, such as Figure 1The Y-axis direction shown in is parallel to the second direction, and the first direction is perpendicular to the second direction.

[0043] Specifically, the transmission assembly 3 also includes a connecting assembly 32, which includes a bearing 322 and a connecting member 321, the connecting member 321 is passed through the inner ring of the bearing 322, and one end of the connecting member 321 is connected to the limit member 4, and the outer ring of the bearing 322 is movably connected to the swinging part 312 along the second direction.

[0044] The end of the connecting member 321 away from the limiting member 4 can be fixedly connected to the inner ring of the bearing 322, or an outer protrusion (not shown in the figure) can be provided. When the connecting member 321 and the limiting member 4 are connected, the inner ring of the bearing 322 is clamped between the outer protrusion and the limiting member 4 to ensure that the limiting member 4 is rotatably connected to the bearing 322.

[0045] Preferably, the connecting member 321 is a screw, one end of the screw having an external thread is threadedly connected to the limit member 4, and the other end of the screw is provided with an external protrusion. When the screw is threadedly connected to the limit member 4, the external protrusion can cooperate with the limit member 4 to clamp the inner ring of the bearing 322 in the middle.

[0046] In addition, a slide groove 3121 is provided along a predetermined direction at one end of the swing portion 312 away from the connecting portion 311, and the bearing 322 is placed in the slide groove 3121 and can move along the path of the slide groove 3121. It should be noted here that one end of the swing portion 312 is connected to the connecting portion 311, and the swing portion 312 extends from one end of the connecting portion 311 away from the output shaft of the driving member 20 toward the rotating shaft of the limiting member 4, that is, the extension direction (also regarded as the length direction) of the swing portion 312 is the predetermined direction, so that the slide groove 3121 is provided along the extension direction of the swing portion 312.

[0047] By setting the bearing 322 and the connecting member 321, relative rotation between the limit member 4 and the swinging part 312 can be achieved. By setting the slide groove 3121 and placing the bearing 322 in the slide groove 3121, the limit member 4 can be moved relative to the swinging part 312 in a predetermined direction. When the driving member 20 drives the swinging part 312 to swing, the limit member 4 rotates relative to the swinging part 312 while moving relative to the swinging part 31 in a predetermined direction. In this way, the limit member 4 can be smoothly transformed between the limiting position and the disengagement position along the second direction.

[0048] In one embodiment, see Figures 1 to 3 The fixed seat 1 is penetrated by a movable channel 12, and the movable channel 12 penetrates between the opposite ends of the fixed seat 1 along the second direction. The limit member 4 is located in the movable channel 12, and the limit member 4 can move along the path of the movable channel 12, and will pass through the limiting position and the disengagement position during the movement.

[0049] Specifically, the limiting member 4 includes a guiding portion 41 and a limiting portion 42 , which can move in the movable channel 12 , the guiding portion 41 is used to guide the moving path of the limiting member 4 , and the limiting portion 42 is used to limit the relative movement between two objects.

[0050] When the limiting member 4 moves, it mainly relies on the limiting portion 42 to limit the two objects. A preferred method is to open through holes on the two relatively movable objects, and the opening direction of the through holes needs to be perpendicular to the movement direction of the two objects when they move relative to each other, or at least have a certain angle. When the limiting portion 42 moves to the limiting position, the limiting portion 42 can be simultaneously inserted into the through holes opened in the two objects, so that the relative movement between the two objects can be limited. When the limiting portion 42 moves to the disengagement position, it will disengage from the two through holes.

[0051] In a specific embodiment, the movable channel 12 includes a limiting guide groove 121 and a through hole 122 that are connected and arranged, the aperture of the through hole 122 is smaller than the radial dimension of the limiting guide groove 121, and the outer shape of the guide portion 41 and the limiting portion 42 can be rectangular or cylindrical, which is not limited here. In this embodiment, the guide portion 41 and the limiting portion 42 are both cylindrical, the guide portion 41 and the limiting portion 42 are coaxially connected, and the radial dimension of the guide portion 41 is larger than the radial dimension of the limiting portion 42.

[0052] The radial dimension of the limiting guide groove 121 needs to match the radial dimension of the guide portion 41 , and the radial dimension of the through hole 122 needs to match the radial dimension of the limiting portion 42 . The guide portion 41 is located in the limiting guide groove 121 , and the limiting portion 42 is penetrated through the through hole 122 .

[0053] By setting the limit guide groove 121 and the guide part 41 in cooperation, the moving direction of the limit member 4 can be guided, and by setting the radial dimensions of the guide part 41 and the limit part 42 to be different, a step structure is formed at the connection between the two, and the corresponding connection between the limit guide groove 121 and the through hole 122 also forms a step structure. In this way, since the radial dimension of the through hole 122 is smaller than the radial dimension of the guide part 41, the movement of the guide part 41 can be limited, so that the limit part 42 can accurately stay in the limit position.

[0054] In one embodiment, see Figures 1 to 3 The limiting mechanism 100 further includes a mounting frame 11, which includes a mounting plate 112 and a plurality of brackets 111 protruding from the mounting plate 112. The plurality of brackets 111 are arranged at intervals, one end of the plurality of brackets 111 is connected to the mounting plate 112, and the other end can be detachably connected to the fixing seat 1 by screws. The driving member 20 can be fixedly connected to the mounting plate 112 by screws, and the mounting plate 112 can provide a fixed support for the driving member 20.

[0055] In addition, when the mounting plate 112 is connected to the fixing base 1 through the bracket 111, the mounting plate 112 and the fixing base 1 are spaced apart. At this time, a placement space is formed between the fixing plate, multiple brackets 111 and the fixing base 1, and the output shaft of the driving member 20 and the transmission assembly 3 are both located in the placement space.

[0056] In a specific embodiment, an optical coupler 13 is also provided on the fixed base 1, and a baffle 14 is provided on the transmission assembly 3. The baffle 14 is specifically fixedly connected to the swinging part 312, and the baffle 14 can swing together with the swinging part 312. The optical coupler 13 is located on the movable path of the baffle 14. The driving member 20 can drive the baffle 14 to pass through the optical coupler 13 by driving the swinging part 312. When the baffle 14 passes through the optical coupler 13, it will cover the optical coupler 13, thereby generating a signal, and judging whether the limit member 4 moves to the limit position or the disengagement position by the signal.

[0057] For example, one setting method is that when the limit part 42 moves to the limit position, the optical coupler 13 can be just blocked by the baffle 14, and the driving member 20 stops driving; another setting method is that when the limit part 42 moves to the disengagement position, the optical coupler 13 can be just blocked by the baffle 14, and the driving member 20 stops driving; a better method is to set up two sets of optical couplers 13 and baffles 14 to cooperate, when the limit part 42 moves to the limit position and the disengagement position, the optical coupler 13 can be blocked by two sets of baffles 14 to obtain signals, so as to stop the driving of the driving member 20 in time.

[0058] On the other hand, please refer to Figure 4 The utility model also provides a basket 300 mechanism, including a fixed frame 200, a basket 300 and the above-mentioned limiting mechanism 100, wherein the basket 300 is arranged in the fixed frame 200, the basket 300 is used to place the sample rack, the basket 300 and the fixed frame 200 can move along a predetermined direction, and the basket 300 can be placed in the fixed frame 200 or separated from the fixed frame 200 when moving in the predetermined direction. The limiting mechanism 100 is connected to the fixed frame 200, and at least part of the structure of the fixed frame 200 and the basket 300 is arranged opposite to each other, and at the opposite position, the fixed frame 200 and the basket 300 are both provided with opposite holes. The limiting member 4 of the limiting mechanism 100 installed on the fixed frame 200 is arranged opposite to the hole, and when the limiting part 42 is located at the limiting position, it can be simultaneously penetrated in the holes of the basket 300 and the fixed frame 200, and at this time, the basket 300 will be restricted from being separated from the fixed frame 200.
