[0058] The utility model discloses a vacuum sealing device, which includes a warehouse body 10, a track 60, a door sealing mechanism 50, a first ear seat 30 and a driving assembly 20, wherein the warehouse body 10 is provided with a door opening 11; the track 60 is arranged at the bottom of the warehouse body 10; the door sealing mechanism 50 is movably arranged on the track 60; the first ear seat 30 is arranged on the door sealing mechanism 50; the driving assembly 20 is arranged in the warehouse body 10; wherein, when the door sealing mechanism 50 moves along the first side, it covers the door opening 11, and when the door sealing mechanism 50 moves to the position of the door opening 11, the driving assembly 20 is connected to the first ear seat 30, and the driving assembly 20 is used to drive the first ear seat 30 to move along a direction perpendicular to the extension direction of the track 60, so as to drive the door sealing mechanism 50 to lock on the door opening 11; the driving assembly 20 is also used to unlock the door sealing mechanism 50, and the door sealing mechanism 50 unseals the door opening 11 when it moves along the second side.

[0059] In one embodiment, please refer to Figures 1 to 3A door opening 11 is provided on one side of the warehouse body 10 , and the warehouse body 10 is connected to the external environment through the door opening 11 .

[0060] The door sealing mechanism 50 is used to seal the door opening 11 of the warehouse body 10 , so that a closed space is formed in the warehouse body 10 and isolated from the external environment.

[0061] The track 60 may be disposed at the bottom of the warehouse body 10 , at the rear side or the front side of the door opening 11 , and the door sealing mechanism 50 may be slidably disposed on the track 60 .

[0062] In order to cope with different usage environments, a door opening 11 is set on any one side of the front or rear side of the warehouse body 10, or on both sides at the same time. Correspondingly, the door sealing mechanism 50 and the track 60 are installed on the side corresponding to the door opening 11 or are set on both sides at the same time.

[0063] In this embodiment, the first side is the left side and the second side is the right side. The first ear seat 30 is installed on the right side of the door sealing mechanism 50, and the door opening 11 is located on the left side of the warehouse body 10. When the door sealing mechanism 50 moves to the left, it covers the door opening 11, thereby closing the warehouse body 10; when the door sealing mechanism 50 moves to the right, it moves away from the door opening 11, thereby opening the warehouse body 10.

[0064] The door seal assembly is driven by the third driving member 23, which is arranged on one side of the track 60. One end of the movable connector 24 is connected to the third driving member 23 by a screw, and the other end is connected to the door seal mechanism 50 by a pin. The door seal mechanism 50 is connected to the third driving member 23 through the movable connector 24, and the driving end of the third driving member 23 drives the door seal assembly to move on the track 60 during the extension and retraction process.

[0065] In the above process, the drive assembly 20 is installed on the right side of the door opening 11. When the door sealing mechanism 50 covers the door opening 11, the position of the drive assembly 20 corresponds to the position of the first ear seat 30, so that the drive assembly 20 and the first ear seat 30 can be docked.

[0066] The driving assembly 20 is used to drive the first ear seat 30 to move along a direction perpendicular to the extension direction of the track 60 , that is, to drive the first ear seat 30 to move forward and backward, thereby indirectly driving the door sealing mechanism 50 to move forward and backward.

[0067] In this embodiment, the door sealing mechanism 50 is installed on the rear side of the warehouse body 10. After the driving component 20 and the first ear seat 30 are docked, the driving end of the driving component 20 retracts, thereby driving the first ear seat 30 to move to the front side, so that the door sealing component is pressed against the edge of the door opening 11, reducing the gap between the door sealing component and the door opening 11, and improving the sealing effect.

[0068] To further improve the sealing effect, a circle of sealing strips can be set around the edge of the door opening 11. The sealing strips can be made of rubber material. The door sealing mechanism 50 is slightly larger than the size of the door opening 11, so that it is tightly attached to the sealing strips around the door opening 11 to improve the sealing effect.

[0069] In the technical solution of the utility model, when the door sealing mechanism 50 is closed, the internal driving assembly 20 is connected to the first ear seat 30, so that during the movement of the driving assembly 20, the door sealing mechanism 50 can be driven to move, and the door sealing mechanism 50 can be closely attached to the door opening 11, thereby improving the sealing between the door sealing mechanism 50 and the warehouse body 10. In addition, the driving assembly 20 is arranged in the warehouse, with a high degree of integration, and the warehouse body 10 can be modularized, which is convenient for disassembly, assembly and debugging, and improves the flexibility of use.

[0070] In one embodiment, please refer to Figure 5 The first ear seat 30 is arranged on the second side of the door sealing mechanism 50, and the first ear seat 30 protrudes toward the driving assembly 20 to form a first limiting groove 31, and the notch of the first limiting groove 31 faces the first side. When the door sealing mechanism 50 moves along the first side, the driving assembly 20 is clamped in the first limiting groove 31 through the notch.

[0071] The driving assembly 20 specifically includes a first driving member 21 . The first driving member 21 can be a cylinder, and a first connector 22 is provided on the driving end of the cylinder.

[0072] When the door sealing assembly moves to the left, the first driving member 21 is located on the left side of the first ear seat 30, and the left side of the first ear seat 30 is the door sealing mechanism 50. Therefore, in order to avoid interference between the door sealing mechanism 50 and the first ear seat 30, the first ear seat 30 should protrude to one side of the first connecting head 22, and the height of the first ear seat 30 should be flush with the height of the first driving member 21.

[0073] In order to ensure that the first ear seat 30 can be docked with the first connector 22 on the first driving member 21, the protruding portion is a groove-shaped structure with an open left side, that is, the left side of the first limiting groove 31 is open. When the first ear seat 30 moves to a position corresponding to the first driving member 21, the first connector 22 can enter the first limiting groove 31 through the open opening.

[0074] Meanwhile, when the first ear seat 30 moves to a position corresponding to the position of the first driving member 21 , the first driving member 21 is located at the front side of the first ear seat 30 .

[0075] In this embodiment, the side wall of the first limiting groove 31 at the front side is taken as an example of the bottom wall, and a first avoidance groove 32 is provided on the bottom wall. The first avoidance groove 32 extends to the left until it is connected with the notch of the first limiting groove 31, so that when the first limiting groove 31 moves to the left, the first connector 22 can enter the first limiting groove 31 through the first avoidance groove 32 to achieve clamping, thereby avoiding the bottom wall from blocking the first connector 22.

[0076] It should be noted that in order to improve the sealing performance, please refer to Figure 3 A first driving member 21 is respectively arranged at the top and the bottom of the bin body 10, so that the upper right corner and the lower right corner of the door sealing mechanism 50 can be pressed at the same time.

[0077] In one embodiment, please refer to Figure 6 The vacuum sealing device also includes a second ear seat 40, which is arranged on the first side of the door sealing mechanism 50. The second ear seat 40 has a second limiting groove 41, and the notch of the second limiting groove 41 faces the first side. When the door sealing mechanism 50 moves along the first side, the driving assembly 20 is clamped in the second limiting groove 41 through the notch.

[0078] The driving assembly 20 specifically also includes a second driving member, and a second connector is provided on the driving end of the second driving member.

[0079] The second driving member is arranged on the left side of the door opening 11. Unlike the first ear seat 30, the left side of the second ear seat 40 is not blocked, so the second ear seat 40 does not need to be raised, and the second ear seat 40 is a groove structure with an open left side, forming a second limiting groove 41.

[0080] Similarly, a second avoidance groove 42 is also provided on the bottom wall of the second limiting groove 41 , so when the door sealing mechanism 50 moves to the left, the second connector directly enters the second limiting groove 41 through the second avoidance groove 42 .

[0081] Similarly, a second driving member is disposed at the top and the bottom of the bin body 10 respectively, so as to simultaneously press the upper left corner and the lower left corner of the door sealing mechanism 50 .

[0082] When the door sealing mechanism 50 is moved into position, the driving ends of the first driving member 21 and the second driving member are retracted, thereby driving the four corners of the door sealing mechanism 50 to be pressed against the door opening 11, thereby improving the overall sealing effect. When unsealing, the driving ends of the first driving member 21 and the second driving member are extended, thereby separating the door sealing mechanism 50 from the door opening 11, and the third driving member 23 drives the door sealing mechanism 50 to move to the right.

[0083] In one embodiment, please refer to Figure 4The door sealing mechanism 50 includes a door body 51, a retaining assembly 52 and a sliding assembly 53. The retaining assembly 52 is arranged at the bottom of the door sealing mechanism 50; the sliding assembly 53 is movably arranged on the retaining assembly 52; the retaining assembly 52 is used to keep the sliding assembly 53 on the track 60 when the door body 51 moves along the direction perpendicular to the extension of the track 60.

[0084] In this embodiment, the shape of the door body 51 is similar to that of the door opening 11 , and the size of the door body 51 is slightly larger than that of the door opening 11 . The door body 51 is used to cover the edge of the door opening 11 , thereby achieving sealing of the warehouse body 10 .

[0085] The sliding assembly 53 is installed in the holding assembly 52, and the sliding assembly 53 can move forward and backward relative to the holding assembly 52. ​​The door body 51 moves left and right on the track 60 through the holding assembly 52 and the sliding assembly 53 on the holding assembly 52.

[0086] In this embodiment, when the door body 51 moves forward and backward under the action of the driving component 20, the retaining component 52 and the door body 51 remain relatively still, and the sliding component 53 moves backward relative to the retaining component 52, so as to remain relatively still with the track 60, thereby preventing the sliding component 53 from detaching from the track 60, and also preventing the sliding component 53 from moving forward and backward with the door body 51 and squeezing and damaging the track 60.

[0087] In one embodiment, please refer to Figures 7 to 9 The retaining assembly 52 includes a retaining frame 521, a guide shaft 522, and an elastic member 523. The retaining frame 521 is arranged at the bottom of the door body 51, and the sliding assembly 53 is arranged on the retaining frame 521; one end of the guide shaft 522 is connected to one side of the retaining frame 521, and the other end passes through the sliding assembly 53 and is connected to the other side of the retaining frame 521; the elastic member 523 is arranged on the guide shaft 522, one end of the elastic member 523 is connected to the sliding assembly 53, and the other end is connected to the retaining frame 521; when the door body 51 drives the retaining frame 521 to move, the elastic member 523 is squeezed to keep the position of the sliding assembly 53 fixed.

[0088] The retaining frame 521 includes four mounting plates 54, which are connected end to end to form a rectangular frame, and the sliding component 53 is arranged in the frame; the guide shaft 522 passes through the sliding component 53, and the two ends of the guide shaft 522 are respectively connected to the two opposite mounting plates 54.

[0089] Both ends of the guide shaft 522 are connected to the left and right sides of the retaining frame 521 respectively. The sliding component 53 is penetrated on the guide shaft 522. When the sliding component 53 moves, it moves left and right along the guide shaft 522 to avoid position deviation.

[0090] One end of the elastic member 523 is directly connected to the side wall of the holder 521, and the other end is directly connected to the side wall of the sliding assembly 53. The elastic member 523 is used to play a role of buffering and resetting, and the elastic member 523 can be a spring. The elastic member 523 is located between the sliding assembly 53 and the side wall of the holder 521. When the holder 521 moves to the left, the spring is squeezed to play a buffering effect to prevent the holder 521 from colliding with the sliding assembly 53.

[0091] When the door 51 is opened, the door 51 loses the pressure of the driving assembly 20, and the retaining frame 521 is subjected to the rightward rebound force of the elastic member 523, so that the retaining frame 521 and the door 51 are reset to be flush with the track 60. This prevents the door 51 from colliding with the warehouse body 10 during the movement after opening, thereby improving the stability of the equipment operation.

[0092] In one embodiment, in order to improve compatibility, an adjustment pad 524 may be further provided between the elastic member 523 and the mounting plate 54 . The adjustment pad 524 may be made of, for example, rubber material.

[0093] The end of the elastic member 523 is directly connected to the adjustment pad 524. When the adjustment pad 524 is thicker, the distance between the elastic member 523 and the mounting plate 54 on the side where the adjustment pad 524 is mounted is larger, and vice versa. By changing the thickness of the adjustment pad 524, the installation position of the elastic member 523 can be adjusted to adapt to various installation spaces and use environments.

[0094] In addition, in order to improve the installation strength of the adjustment pad 524, a cover plate 525 is provided on the outer side wall of the retainer 521. The adjustment pad 524 passes through the mounting plate 54 and is connected to the cover plate 525 by a fixing structure such as screws, and a gasket is used at the abutment position to improve the connection strength.

[0095] In one embodiment, the retaining assembly 52 further includes a limiting sleeve 55 , which is disposed on the sliding assembly 53 , and one end of the elastic member 523 is engaged in the limiting sleeve 55 , and the other end is connected to the retaining frame 521 .

[0096] The limiting sleeve 55 is annular, mounted on the side wall of the sliding assembly 53, and sleeved around the outer periphery of the guide shaft 522. A groove structure is provided between the limiting sleeve 55 and the guide shaft 522, and the end of the elastic member 523 is clamped in the groove structure, which plays a role in limiting the elastic member 523 and preventing the elastic member 523 from being deformed after being squeezed.

[0097] In one embodiment, the sliding assembly 53 includes a pulley 532, a connecting rod 533, a rotating shaft 534 and two oppositely arranged connecting plates 531; the pulley 532 is arranged between the two connecting plates 531; the two ends of the connecting rod 533 are respectively connected to the two connecting plates 531; one end of the rotating shaft 534 is connected to one side of the retaining assembly 52, and the other end passes through the pulley 532 and the two connecting plates 531 and is connected to the other side of the retaining assembly 52.

[0098] The rotating shaft 534 passes through the two connecting plates 531 and is directly connected to the mounting plates 54 on both sides. The pulley 532 is passed through the rotating shaft 534 to realize rotation on the rotating shaft 534 .

[0099] The pulley 532 has a conical recessed structure in the middle, and the track 60 has a similar raised structure. When engaged, the raised structure of the track 60 engages with the recessed structure of the pulley 532 .

[0100] The connecting plate 531 has an avoidance hole for the guide shaft 522 to pass through, and the limiting sleeve 55 is arranged on the connecting plate 531 on the side away from the mounting plate 54 provided with the adjustment pad 524, and the limiting sleeve 55 and the avoidance hole are arranged concentrically. One end of the elastic member 523 is clamped in the limiting sleeve 55, and the other end passes through the avoidance hole on the other connecting plate 531 and is connected to the adjustment pad 524.

[0101] An adjustment pad 524 is set on the right mounting plate 54. When the door body 51 moves to the left, the right mounting plate 54 is driven to move to the left. The pulley 532 is limited on the slide rail through the cooperation of the recessed structure and the raised structure, and the spring is pressed to the left, thereby realizing relative movement between the retaining frame 521 and the pulley 532.

[0102] In actual use, the door body 51 is usually arranged close to the door body 51, so even if the door body 51 is subjected to the pressure of the driving assembly 20, the actual distance of movement to the left is small, which can be achieved by the limiting effect between the pulley 532 and the track 60. When the moving distance is large, an external limiting mechanism, such as a limiting rod, can be used to abut the right side of the pulley 532, so as to keep the pulley 532 and the track 60 relatively still.

[0103] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
