1. A cabin entry-and-exit structure of an analysis device, configured to transport a loading part for bearing a detection chip in the analysis device, for entry or exit of the loading part into or out of a cabin,
the cabin entry-and-exit structure comprising:
a carrier body configured to receive the loading part;
a guide support assembly disposed on a base board in a cabin body of the analysis device and is configured to bear the carrier body, and the guide support assembly is movably connected to the carrier body such that the carrier body is movable along an entry direction into the cabin or an exit direction out of the cabin; and
a door opening-and-closing assembly disposed on the base board and located on a side of the carrier body far away from a cabin door, wherein the door opening-and-closing assembly is configured to apply a pushing force to the carrier body towards the exit direction when the carrier body is subjected to a pressing force such that the carrier body moves to a cabin opening position, and to lock the carrier body at a cabin closing position when the carrier body is subjected to a pressing force again;
wherein the guide support assembly further comprises;
a support component disposed on the base board and configured to support the carrier body, wherein the support component comprises;
a first support subcomponent, wherein the first support subcomponent is fixedly connected to the base board, and one of the guide rail and the slider is disposed on a surface of the first support subcomponent facing away from the base board;
a second support subcomponent, wherein the second support subcomponent is fixedly connected to a surface of the carrier body facing towards the base board, located proximal to one end of the carrier body and distal from the cabin door;
at least one roller,
a guide rail; and
a slider,
wherein the one of the guide rail and the slider is disposed on a surface of the support component facing away from the base board, and the other of the guide rail and the slider is disposed on a surface of the carrier body facing towards the base board; and
the guide rail and the slider are slidably connected along the entry direction or the exit direction; and
the at least one roller is disposed on the second support subcomponent and is in rolling contact with the base board; and
wherein the door opening-and-closing assembly further comprises;
a fixing stand,
a limiting structure disposed on the fixing stand, and
an elastic member connected to the limiting structure,
wherein the fixing stand is fixed on the base board and located at a side of the carrier body distal from the cabin door;
wherein the limiting structure is connected to the elastic member and is detachably connected to the carrier body, and the limiting structure is further configured to unlock the carrier body when the carrier body at the cabin closing position moves to a trigger position along the entry direction under the pressing force, and to apply a pushing force to the carrier body towards the exit direction under an elastic force of the elastic member, so that the carrier body moves to the cabin opening position; and
wherein the limiting structure locks the carrier body at the cabin closing position when the carrier body at the cabin opening position moves to the trigger position along the entry direction under the pressing force; and
wherein the limiting structure further comprises;
a housing,
a limiting member, and
a locking member,
wherein the housing has an opening at a side opposite to the carrier body, and a guide limiting part is disposed at an inner surface of the housing;
wherein the elastic member is positioned in an internal space of the housing, a fixed end of the elastic member is fixedly connected to the housing, and a telescopic end of the elastic member is fixedly connected to the locking member:
wherein the limiting member is rotatably connected to the telescopic end of the elastic member, and the limiting member is configured such that when the telescopic end of the elastic member is stretched and retracted in a direction close to or far away from the opening, the elastic member is configured to drive the limiting member to slide along the guide limiting part, so that the limiting member sequentially passes through a first position, a second position and a third position from an initial position,
wherein when the limiting member is at the initial position, the carrier body is positioned at the cabin opening position and when the limiting member is at the first position or the third position, the carrier body is positioned at the trigger position; when the limiting member is at the second position, the limiting member and the guide limiting part are relatively fixed, and the carrier body is positioned at the cabin closing position; and
the locking member is configured to move into and out of the internal space of the housing through the opening, and the locking member is detachably connected to the carrier body and is configured to remain connected to the carrier body in a process where the carrier body moves from the cabin opening position to the cabin closing position, such that the carrier body is locked at the cabin closing position; and
the locking member is separated from the carrier body in a process where the carrier body moves from the cabin closing position to the cabin opening position, so that the carrier body independently moves to the cabin opening position.
