Technical Field

[0001] The utility model relates to an automatic cabin door opening and closing connecting rod mechanism and a medical cabin, and is applicable to the field of medical instruments. Background Art

[0002] Currently, medical cabins, such as hyperbaric oxygen chambers, are used in some disease treatment fields to provide patients with specialized treatment environments. Existing medical cabin equipment often uses manual door opening and closing. However, manual door opening and closing methods, due to the inability to fully regulate operator operation, pose the risk of damage to the equipment due to forceful operation. Furthermore, manual door closing methods cannot restrict the door's movement during opening and closing, nor can they determine and guarantee the entire door's sealing status. Utility Model Content

[0003] The technical problem to be solved by the utility model is: in view of the above-mentioned problems, an automatic cabin door opening and closing connecting rod mechanism and a medical cabin are provided.

[0004] The technical solution adopted by the utility model is: an automatic hatch door opening and closing connecting rod mechanism, comprising:

[0005] An electric cylinder is fixedly mounted on the side of the cabin body, wherein the actuating end of the electric cylinder is connected to the cabin door via a connecting rod, the actuating end of the electric cylinder is connected to the first end of the connecting rod via axis I, and the second end of the connecting rod is fixed to the cabin door;

[0006] A slider is mounted on the side of the cabin via a guide mechanism. The slider can only move back and forth along the axis of the electric cylinder within a preset range of movement under the action of the guide mechanism.

[0007] A connecting bracket, a first end of which is connected to the slider via shaft II, and a second end of which is connected to the cabin door via shaft III;

[0008] The elastic mechanism is connected to the slider and is used to provide the slider with a force that enables the slider to move toward the action end of the electric cylinder.

[0009] The guide mechanism has at least one guide rod, which is arranged parallel to the axis of the electric cylinder, and the two ends of the guide rod are fixed to the side of the cabin through the mounting seat I and the mounting seat II respectively;

[0010] The sliding block is provided with guide holes corresponding one to one with the guide rods on the guide mechanism, and the shape and size of the guide holes are adapted to the shape and size of the cross section of the guide rods.

[0011] The guide mechanism has two guide rods, which are respectively located on both sides of the electric cylinder.

[0012] The elastic mechanism comprises a spring which is sleeved on the guide rod, and the end of the spring facing the hatch contacts the sliding block.

[0013] The distance from the second end of the connecting rod to the axis III is equal to the distance from the electric cylinder to the axis II.

[0014] A medical cabin is characterized by having the above-mentioned automatic cabin door opening and closing connecting rod mechanism.

[0015] A guide pin is provided on the hatch of the medical cabin, and a trigger switch which can cooperate with the guide pin when the hatch is closed in place is provided on the cabin body of the medical cabin.

[0016] The beneficial effects of the present invention are as follows: the present invention forms a multi-link mechanism by cooperating the electric cylinder, shaft I, connecting rod, hatch, slider, shaft II, connecting bracket and shaft III, and the multi-link mechanism can drive the hatch to rotate around shaft III through the electric cylinder, thereby realizing automatic opening and closing of the hatch, thereby avoiding the safety hazards caused by manual opening and closing in the prior art.

[0017] The utility model utilizes an electric cylinder to realize the opening and closing of the hatch, thereby utilizing the characteristic of the electric cylinder that can be precisely controlled to maintain the movement position of the hatch, unify the movement speed, and reduce the risk of equipment failure.

[0018] The utility model divides the opening and closing process of the hatch into two stages by cooperating with a slider, an elastic mechanism and a guide mechanism. In the first stage of hatch opening, the electric cylinder cooperates with the elastic mechanism to synchronously move the hatch, the connecting bracket and the slider forward; in the second stage of hatch opening, the electric cylinder pushes the hatch to rotate around axis III via the connecting rod, thereby realizing hatch opening; in the first stage of hatch closing, the electric cylinder pulls the hatch to rotate around axis III via the connecting rod; in the second stage of hatch closing, the electric cylinder pulls the hatch, the connecting bracket, the slider and the like via the connecting rod to overcome the action force of the elastic mechanism and move backward, thereby realizing hatch closing.

[0019] The opening and closing process of the hatch in the utility model is divided into two stages. When the hatch rotates around axis III, a certain distance is maintained between the hatch and the cabin body to avoid interference and friction between the hatch and the cabin body when the hatch rotates around axis III.

[0030] Example 1: Figures 1 to 3 As shown, this embodiment is an automatic hatch 11 opening and closing linkage mechanism, which is used to install the hatch 11 on the cabin body 15, including an electric cylinder 1, a connecting rod 10, a slider 4, a guide mechanism, a connecting bracket 13 and an elastic mechanism.

[0031] In this embodiment, the electric cylinder 1 is fixedly installed on the side of the cabin body 15 via the electric cylinder mounting base 2 and the fixing hoop 3, and the actuating end of the electric cylinder 1 faces the cabin door 11. The actuating end of the electric cylinder 1 is connected to one end of the connecting rod 10 via the vertically arranged axis Ⅰ9, and the other end of the connecting rod 10 is fixed on the cabin door 11.

[0032] In this example, the slider 4 is installed on the side of the cabin 15 via a guide mechanism. Under the action of the guide mechanism, the slider 4 can only move back and forth along the axis direction of the electric cylinder 1 within a preset movement range.

[0033] In this embodiment, the guide mechanism has two guide rods 5, which are arranged parallel to the axis of the electric cylinder 1 and are respectively located on both sides of the electric cylinder 1. The ends of the guide rods 5 facing the cabin door 11 are fixed to the side of the cabin body 15 through the mounting seat Ⅰ6, and the other ends of the guide rods 5 are fixed to the side of the cabin body 15 through the mounting seat Ⅱ7; the slider 4 is provided with two guide holes corresponding to the two guide rods 5 one by one, and the shape and size of the guide holes are adapted to the shape and size of the cross-section of the guide rod 5. The slider 4 is installed on the guide rod 5 through the guide holes, and the slider 4 can move back and forth between the mounting seats Ⅰ6 and Ⅱ along the axis direction of the guide rod 5.

[0034] In order to avoid position conflict between the slider 4 and the electric cylinder 1 during movement, in this embodiment, a groove corresponding to the position of the electric cylinder 1 is provided on the slider 4.

[0035] In this embodiment, the slider 4 is connected to one end of the connecting bracket 13 via a vertically arranged shaft II 12 , and the other end of the connecting bracket 13 is connected to a side edge of the hatch 11 via a vertically arranged shaft III 14 .

[0036] In this example, axis III 14 is the rotation axis for opening and closing the hatch door 11. The electric cylinder 1 pushes and pulls the hatch door 11 through the connecting rod 10, causing the hatch door 11 to rotate around axis III 14, thereby realizing automatic opening and closing of the hatch door 11.

[0037] In this embodiment, the connection end between the connecting rod 10 and the hatch 11 is located on the edge side of the shaft III 14 away from the hatch 11 , and a certain distance is left between the connection end between the connecting rod 10 and the hatch 11 and the shaft III 14 , which is the same as the distance from the electric cylinder 1 to the shaft II 12 .

[0038] In this embodiment, an elastic mechanism is provided on the slider 4, and the elastic mechanism adopts a spring 8. The spring 8 is mounted between the slider 4 and the mounting seat II 7 on the guide rod 5. The end of the spring 8 facing the cabin door 11 is in contact with the slider 4, so that the spring 8 can provide the slider 4 with a force that enables the slider 4 to move toward the cabin door 11.

[0039] The working principle of the opening and closing linkage mechanism of the automated hatch 11 in this embodiment is as follows:

[0040] When the hatch 11 is closed, the electric cylinder 1 is in a retracted state, the slider 4 is located near the mounting seat II 7, and the spring 8 is compressed;

[0041] During the first stage of hatch door 11 opening, the actuating end of electric cylinder 1 extends, pushing hatch door 11 forward via connecting rod 10. Simultaneously, slide 4 moves forward synchronously under the action of spring 8. Connecting bracket 13 and shaft III 14, which are directly or indirectly connected to slide 4, also move forward synchronously. Since connecting rod 10 and shaft III 14 move forward synchronously, hatch door 11 does not rotate about shaft III 14 during this stage.

[0042] When the slider 4 moves forward and contacts the mounting seat I6, the hatch 11 opens and enters the second stage. Due to the obstruction of the mounting seat I6, the slider 4 cannot move forward any further, and the shaft III 14 also stops moving forward. The connecting rod 10 continues to move forward under the action of the electric cylinder 1, causing the hatch 11 to rotate around the shaft III 14 under the push of the connecting rod 10, and the hatch 11 is opened (see Figure 4 ).

[0043] In the first stage of closing the hatch 11, the actuating end of the electric cylinder 1 retracts, and the hatch 11 is pulled to rotate around the axis III 14 via the connecting rod 10, gradually closing the hatch 11;

[0044] When the electric cylinder 1 can no longer pull the hatch 11 to continue rotating around the axis III 14 via the connecting rod 10, the hatch 11 closes and enters the second stage. The pulling force of the connecting rod 10 on the hatch 11 is transmitted to the slider 4 via the axis III 14, the connecting bracket 13 and the axis II 12, so that the slider 4 overcomes the force of the spring 8 and moves toward the end of the mounting seat II 7. At this time, the hatch 11, the connecting bracket 13 and the slider 4 move backward synchronously until the hatch 11 is closed in place (see Figure 5 ).

[0045] Example 2: This example is a medical cabin, which has a cabin body 15 and a cabin door 11. The cabin door 11 is installed on the cabin body 15 via the automatic cabin door 11 opening and closing linkage mechanism in Example 1.

[0046] In this embodiment, in order to avoid the situation where the electric cylinder 1 runs into position but the hatch 11 is not in position due to action errors, a guide pin is provided on the hatch 11, and a trigger switch corresponding to the guide pin on the hatch 11 is provided on the cabin body 15. When the hatch 11 is closed into position, the guide pin on the hatch 11 cooperates with the trigger switch on the cabin body 15 to generate an in-position signal and send the in-position signal to the host computer.
