Description

Technical Field

[0001] This utility model relates to the field of sealing door technology, specifically a sealing door for protecting sealing strips. Background Technology

[0002] In the medical industry, equipment such as medical device sterilizers and instrument dryers are widely used. These devices typically consist of a cabinet to hold medical devices, sealed by a movable door, allowing for the sterilization and drying of the devices using onboard sterilization and drying equipment. However, most current models use a frame that moves parallel to the cabinet opening, along with a sealing door mounted on the frame. As the frame moves to the opening and continues to move, the sealing door, when restricted, moves obliquely along with the frame to seal the opening. However, this method has a significant drawback: the obliquely moving sealing door, while applying pressure to seal the inside of the cabinet, continues to move parallel to the frame for a distance before achieving a complete seal. This means that any sealing strips that haven't been fully compressed can be lifted by the sealing door upon contact, affecting the sealing effect and reducing the safety and reliability of the equipment. Utility Model Content

[0003] The present invention provides a sealing door body for protecting the sealing strip, which solves the problem that the sealing strip is prone to flipping up during the sealing process of existing sealing door bodies, thus affecting the sealing effect.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A sealing door for protecting a sealing strip includes a housing frame, a smooth door outer frame slidably connected to the housing frame at both ends, a drive mechanism disposed on the housing frame for driving the smooth door outer frame to reciprocate and slide, and a door body mounted on the smooth door outer frame. The door body includes a sealing door, two guide plates located at both ends of the sealing door and arranged parallel to the smooth door outer frame, a limiting frame corresponding to the outer side of the guide plates and arranged parallel to the smooth door outer frame, and a limiting frame disposed on the housing frame for limiting the ultimate displacement of the sealing door. Multiple guide wheels and multiple support wheels are provided at both ends of the sealing door. The guide plates on the same side have folded guide holes that cooperate with the guide wheels and supporting through holes for the support wheels to pass through. The support wheels pass through the cooperating through holes and are supported on the inner plane of the limiting frame. The smooth door outer frame has limiting through holes that cooperate with the limiting frame.

[0006] Specifically, a tension spring is installed at one end of the smooth door frame, and the other end of the tension spring is installed on the sealing door. Specifically, both ends of the tension spring can be detachably connected to the smooth door frame and the sealing door, respectively. Specifically, bolts can be used to secure the rings at both ends of the tension spring. The tension spring effectively assists the sealing door in resetting when the smooth door frame resets.

[0007] The two guide plates located at both ends of the sealing door and parallel to the outer frame of the smooth door refer to two guide plates located at the upper and lower ends of the sealing door, respectively, with their positions parallel and arranged on the outer frame of the smooth door. The limiting frame corresponding to the outer side of the guide plates and parallel to the outer frame of the smooth door refers to the limiting frame being parallel to the guide plates and corresponding to the outer side of the guide plates, arranged on the outer frame of the smooth door. The folded guide hole and the support through hole have the same shape. The limiting frame that restricts the ultimate displacement of the sealing door refers to the frame that restricts the sealing door after it has moved to the opening of the box, preventing it from continuing to move, so that it can only move perpendicular to the opening of the box while the outer frame of the smooth door continues to move smoothly. The limiting through hole on the outer frame of the smooth door that cooperates with the limiting frame means that the limiting frame can penetrate the limiting through hole and abut against the sealing door, thereby preventing the sealing door from moving further under its restriction. The folded guide hole is composed of an inclined waist hole relative to the box and a vertical waist hole relative to the box. Multiple refers to two or more.

[0008] Working principle: The sealing door is supported by support rollers and a limiting frame. When the drive mechanism is started, it drives the smooth door frame to slide on the box frame, and the smooth door frame in turn drives the door to move. When the sealing door moves to the corresponding position at the box opening, the limiting frame passes through the limiting hole and abuts against the sealing door, preventing it from moving parallel. At this time, the guide wheel guides in the folded guide hole. As the smooth door frame continues to move parallel, the guide wheel slides from the oblique waist hole to the vertical waist hole, so that the sealing door is pressed vertically into the box opening, completing the sealing action. The support wheel slides in the plane inside the limiting frame to ensure the stability of the sealing door movement. Conversely, the drive mechanism drives the smooth door frame to move in the opposite direction, so that the smooth door frame drives the sealing door to open the box, exposing the box opening. By adopting this structure and setting up folded guide holes and limiting frames, when the sealing door moves to the opening of the box, the limiting frames restrict its parallel displacement. Under the guidance of the folded guide holes, the guide wheels ensure that the sealing door can only be pressed into the box, preventing the sealing door from causing the sealing strip to flip up, reducing the possibility of damage to the sealing strip, effectively protecting the sealing strip, and improving the sealing effect and reliability of the sealing door.

[0009] Furthermore, the upper end of the smooth door outer frame is slidably connected to the box frame via an upper sliding assembly, and the lower end of the smooth door outer frame is slidably connected to the box frame via a lower sliding assembly. Specifically, the upper sliding assembly includes an upper guide rod disposed on the box frame and multiple concave pulleys rotatably connected to the upper end of the smooth door outer frame, the annular grooves of the concave pulleys engaging with the upper guide rod. The lower sliding assembly includes a lower guide rod disposed on the box frame and multiple sliders disposed at the lower end of the smooth door outer frame, the sliders slidably connected to the lower guide rod. This structure ensures accurate sliding of the smooth door outer frame and stability during its sliding displacement.

[0010] Furthermore, the drive mechanism includes a rack mounted on the outer frame of the smooth door, a geared motor mounted on the housing frame, and a transmission gear mounted on the output end of the geared motor and meshing with the rack. With this structure, when the geared motor is energized, the transmission gear at its output end rotates and meshes with the rack on the outer frame of the smooth door, converting the rotational motion of the motor into the linear reciprocating motion of the outer frame of the smooth door. By controlling the forward and reverse rotation of the geared motor, the direction of movement of the outer frame of the smooth door is controlled, thereby driving the door to move accurately to the corresponding position to complete the sealing or opening action. This structure is compact, has high transmission efficiency, and utilizes the stability of gear and rack transmission and the controllability of the geared motor to achieve precise control of the movement of the sealing door, resulting in a high degree of automation.

[0011] Furthermore, the guide wheel is a bearing. Specifically, the bearing can be installed on the sealing door in any existing way, as long as it can move within the folded guide hole and drive the sealing door to move.

[0012] Furthermore, the limiting frame includes a mounting bracket disposed on the housing frame and limiting wheels disposed on the mounting bracket. With this structure, when the sealing door moves to the housing opening, the limiting wheels on the limiting frame contact the side wall of the sealing door through the limiting through-holes in the outer frame of the smooth door. As the outer frame of the smooth door continues to move, the limiting wheels abut against the sealing door, limiting its parallel displacement; and the limiting wheels reduce friction during vertical displacement of the sealing door.

[0013] Furthermore, both the support wheel and the limiting wheel utilize bullseye ball bearings. These bullseye ball bearings can be installed in their respective positions using any existing technological method, as long as the corresponding technical principle is achieved. This structure significantly reduces friction between the support wheel / limiting wheel and the contact components, resulting in smoother movement of the sealing door.

[0014] Beneficial effects: By setting folded guide holes and limiting frames, when the sealing door moves to the opening of the housing, the limiting frames restrict its parallel displacement. Under the guidance of the folded guide holes, the guide wheels ensure that the sealing door can only be pressed into the housing, preventing the sealing door from causing the sealing strip to flip up, reducing the possibility of damage to the sealing strip, effectively protecting the sealing strip, and improving the sealing effect and reliability of the sealing door body. The smooth door frame is connected to the housing frame through upper and lower sliding components, ensuring the smooth movement of the smooth door frame. The drive mechanism adopts a combination of geared motor, transmission gear and rack, which has a simple structure, stable transmission, and facilitates the control of the movement of the sealing door body, improving the automation level of the equipment. The guide wheels use bearings, and the support wheels and limiting wheels use bullseye ball bearings, which can effectively reduce frictional resistance, reduce wear, extend the service life of each component, and ensure the smooth movement of the sealing door on the limiting frame.

[0023] The following will provide a more detailed description of a sealing door body technical solution for protecting sealing strips, based on embodiments of the present invention.

[0024] In this description, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this context based on the specific circumstances.

[0025] like Figures 1 to 7As shown, a sealing door body for protecting the sealing strip in this embodiment includes a housing frame 1, a smooth door outer frame 2 slidably connected to the housing frame 1 at both ends, a drive mechanism 3 disposed on the housing frame 1 for driving the smooth door outer frame 2 to reciprocate sliding displacement, and a door body installed on the smooth door outer frame 2; the door body includes a sealing door 4, two guide plates 5 located at both ends of the sealing door 4 and arranged parallel to the smooth door outer frame 2, and a door body corresponding to the outer side of the guide plates 5 and arranged parallel to the smooth door outer frame. The sealing door 4 is equipped with a limiting bracket 6 on the upper and lower ends of the sealing door 4 and a limiting bracket 7 on the box frame 1 to limit the extreme displacement of the sealing door 4. Multiple guide wheels 8 and multiple support wheels 9 are provided at both ends of the sealing door 4. A folded guide hole 10 for the guide wheel 8 and a support through hole 11 for the support wheel 9 to pass through are provided on the guide plate 5 on the same side. The support wheel 9 passes through the support through hole 11 and is supported on the inner plane of the limiting bracket 6. A limiting through hole 12 for the limiting bracket 7 is provided on the outer frame 2 of the smooth door. The two guide plates 5 located at both ends of the sealing door 4 and parallel to each other on the outer frame 2 of the smooth door refer to two guide plates 5 located at the upper and lower ends of the sealing door 4, with their positions parallel and arranged on the outer frame 2 of the smooth door. The limiting bracket 6, corresponding to the outer side of the guide plate 5 and parallel to the outer frame 2 of the smooth door, refers to the limiting bracket 6 being parallel to the guide plate 5 and arranged on the outer side of the guide plate 5 on the outer frame 2 of the smooth door. The folded guide hole 10 and the supporting through hole 11 have the same shape. The limiting frame 7, which restricts the ultimate displacement of the sealing door 4, means that after the sealing door 4 is moved to the opening of the box, it is restricted to prevent it from continuing to move, so that it can only move perpendicular to the opening of the box while the smooth door frame 2 continues to move smoothly. The limiting through hole 12 on the smooth door frame 2, which is provided to cooperate with the limiting frame 7, means that the limiting frame 7 can pass through the limiting through hole 12 and abut against the sealing door 4, so that the sealing door 4 cannot move further under its restriction. The folded guide hole 10 is integrally formed by an oblique waist hole that is oblique to the box and a vertical waist hole that is perpendicular to the box. The upper end of the smooth door frame 2 is slidably connected to the box frame 1 through the upper sliding assembly 13, and the lower end of the smooth door frame 2 is slidably connected to the box frame 1 through the lower sliding assembly 14. Specifically, the upper sliding assembly 13 includes an upper guide rod disposed on the housing frame 1 and a plurality of concave pulleys rotatably connected to the upper end of the smooth door outer frame 2, the annular grooves of the concave pulleys cooperating with the upper guide rod. The lower sliding assembly 14 includes a lower guide rod disposed on the housing frame 1 and a plurality of sliders disposed at the lower end of the smooth door outer frame 2, the sliders being slidably connected to the lower guide rod.The drive mechanism 3 includes a rack 301 mounted on the outer frame 2 of the smooth door, a reduction motor 302 mounted on the housing frame 1, and a transmission gear 303 mounted on the output end of the reduction motor 302 and meshing with the rack 301. The guide wheel 8 uses a bearing. The limiting frame 7 includes a mounting bracket 701 mounted on the housing frame 1 and a limiting wheel 702 mounted on the mounting bracket 701. Specifically, one end of a tension spring 15 is mounted on the outer frame of the smooth door, and the other end of the tension spring 15 is mounted on the sealing door. Specifically, both ends of the tension spring 15 can be detachably connected to the outer frame of the smooth door and the sealing door, respectively. Specifically, bolts can be used to fix the rings at both ends of the tension spring 15.

[0026] Working principle: The sealing door 4 is supported by the support roller 9 and the limiting frame 6. When the drive mechanism 3 is started, it drives the smooth door frame 2 to slide on the box frame 1, and the smooth door frame 2 in turn drives the door to move. When the sealing door 4 moves to the corresponding position at the box opening, the limiting frame 7 passes through the limiting through hole 12 and abuts against the sealing door 4 to prevent it from moving parallel. At this time, the guide wheel 8 guides in the folded guide hole 10. As the smooth door frame 2 continues to move parallel, the guide wheel 8 slides from the oblique waist hole to the vertical waist hole, so that the sealing door 4 is pressed vertically into the box opening to complete the sealing action. The support wheel 9 slides in the plane inside the limiting frame 6 to ensure the stable movement of the sealing door 4. Conversely, the drive mechanism 3 drives the smooth door frame 2 to move in the opposite direction, so that the smooth door frame 2 drives the sealing door 4 to open the box and expose the box opening. With this structure, by setting the folded guide hole 10 and the limiting frame 7, when the sealing door 4 moves to the opening of the box, the limiting frame 7 restricts its parallel displacement. Under the guidance of the folded guide hole 10, the guide wheel 8 ensures that the sealing door 4 can only be pressed into the box, preventing the sealing door 4 from causing the sealing strip to flip up, reducing the possibility of damage to the sealing strip, effectively protecting the sealing strip, and improving the sealing effect and reliability of the sealing door body. The smooth door outer frame 2 is connected to the box frame 1 through the upper sliding component 13 and the lower sliding component 14, which can ensure the smooth movement of the smooth door outer frame 2. The drive mechanism 3 adopts a combination of a geared motor 302, a transmission gear 303 and a rack 301, which has a simple structure, stable transmission, and is easy to control the movement of the sealing door body, improving the automation level of the equipment. The guide wheel 8 adopts bearings, and the support wheel 9 and the limiting wheel 702 adopt bullseye ball bearings, which can effectively reduce frictional resistance, reduce wear, extend the service life of each component, and at the same time ensure the smooth movement of the sealing door 4 on the limiting frame 6.

The power supply is also common knowledge or conventional technology in this field, so the control method and circuit connection will not be explained in detail here.
