Description

Technical Field

[0001] This utility model relates to the field of door structure technology, specifically a mechanism for rapid disengagement of a lateral sliding door after a malfunction. Background Technology

[0002] In the medical industry, equipment such as medical device sterilizers and instrument dryers are widely used. These devices typically have a housing 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, existing technology has certain drawbacks. In the event of a power outage or a malfunction in the drive mechanism, the door may seal the housing, preventing the timely removal of medical devices. This not only disrupts normal medical procedures but may also delay urgent use of medical devices, causing unnecessary losses and inconvenience. Utility Model Content

[0003] This utility model mainly provides a quick disengagement mechanism after a lateral sliding door malfunctions, solving the problem that in existing medical device disinfection and drying equipment, the door seals the box when there is a power outage or the drive mechanism malfunctions, making it impossible to remove the medical devices.

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

[0005] A mechanism for quick disengagement of a lateral sliding door after a malfunction includes a housing frame, a smooth door outer frame, and a door body mounted on the smooth door outer frame. An upper sliding assembly is provided between the upper end of the smooth door outer frame and the housing frame, and a lower sliding assembly is provided between the lower end of the smooth door outer frame and the housing frame. A rack is provided on the smooth door outer frame, and a geared motor is provided on the housing frame corresponding to the inner side of the rack. A transmission gear that meshes with the rack is slidably sleeved on the output shaft of the geared motor, and the transmission gear rotates under the drive of the geared motor. An elastic support member is provided on the output shaft for pushing outward and supporting the transmission gear. The door body can be mounted on the smooth door outer frame using any existing method, as long as it can seal the opening of the housing after installation, fixation, and movement. This is not the technical problem to be solved in this application and therefore will not be described in detail. The geared motor can use existing technology, such as a worm gear reducer motor. Working Principle: Under normal operating conditions, the geared motor drives the output shaft and transmission gear to rotate. The transmission gear meshes with the rack on the outer frame of the sliding door, thereby driving the outer frame and door body to slide laterally along the upper and lower sliding components, realizing the normal opening and closing operation of the door. At this time, the elastic support is in a naturally extended state, providing outward support force for the transmission gear and ensuring stable meshing between the transmission gear and the rack. When the equipment experiences a power outage or a drive mechanism malfunction, the operator manually pushes the transmission gear inward. The transmission gear slides inward on the output shaft against the elastic force of the elastic support, disengaging the transmission gear from the rack. At this time, the outer frame and door body of the sliding door are no longer restricted by the displacement of the transmission gear and rack. The operator can manually push the outer frame of the sliding door to slide laterally along the upper and lower sliding components, thereby opening the door and removing the medical instruments inside the box. After the operation is completed, the transmission gear is released. Under the action of the spring force, the transmission gear automatically resets, restoring its initial position relationship with the rack, preparing for normal use next time. With this structure, when the equipment loses power or the drive mechanism malfunctions, the operator can quickly disengage the transmission gear from the rack by pushing it inward on the output shaft. This releases the displacement restriction on the smooth door frame, allowing the smooth door frame and door to slide easily, open the housing, and promptly remove the medical devices inside. This effectively solves the problem of existing equipment doors being sealed shut, preventing the removal of devices and greatly improving the equipment's emergency handling capabilities. The upper and lower sliding components work together to provide stable sliding guidance for the smooth door frame and door from both ends, ensuring that the door can open and close smoothly under normal operating conditions.

[0006] Furthermore, the upper sliding assembly includes an upper guide rod disposed on the housing frame and multiple concave pulleys rotatably connected to the upper end of the smooth door outer frame. The annular grooves of the concave pulleys engage with the upper guide rod. Specifically, the cross-section of the annular groove is semi-circular, allowing it to engage with the cylindrical upper guide rod. The two components employ a clearance fit and smooth surface treatment (such as chrome plating on the guide rod and polishing of the groove inner wall) to reduce friction and ensure smooth door sliding. This structure provides stable and flexible sliding guidance for the upper end of the smooth door outer frame, reducing friction during sliding and ensuring smooth door sliding; simultaneously, the upper guide rod's position within the annular groove provides axial positioning relative to the concave pulleys.

[0007] Furthermore, the lower sliding assembly includes a lower guide rod disposed on the housing frame and multiple sliders disposed at the lower end of the smooth door outer frame, the sliders being slidably connected to the lower guide rod. Specifically, the sliders can be slidably connected to the lower guide rod in any existing manner. With this structure, the lower sliding assembly and the upper sliding assembly cooperate to ensure stable sliding of the smooth door outer frame and the door body from both ends, enabling the door body to open and close smoothly under normal operating conditions.

[0008] Furthermore, a spline is provided between the transmission gear and the output shaft of the geared motor, and a gear baffle is detachably connected to the outer end of the output shaft of the geared motor. With this structure, the spline enables a sliding connection and power transmission between the transmission gear and the output shaft, ensuring that the transmission gear can both slide axially on the output shaft and rotate with it. The detachable gear baffle serves to fix and protect the transmission gear, preventing it from detaching from the output shaft during normal operation.

[0009] Furthermore, the elastic element is a spring, and a limit plate is provided on the output shaft of the geared motor. The spring is sleeved on the output shaft of the geared motor between the transmission gear and the limit plate. With this structure, the spring acts as an elastic support element, providing outward support force to the transmission gear during normal operation, ensuring a stable meshing state with the rack. In the event of a power outage or drive mechanism failure, the transmission gear is pushed inward, compressing the spring and disengaging from the rack, thereby releasing the displacement restriction on the outer frame of the sliding door.

[0010] Beneficial effects: When the equipment loses power or the drive mechanism malfunctions, the operator can quickly disengage the transmission gear from the rack by pushing it inward on the output shaft, thus releasing the displacement restriction on the smooth door frame. This allows the smooth door frame and door to slide easily, opening the enclosure and allowing timely removal of medical devices from inside. This effectively solves the problem of existing equipment doors being sealed shut, preventing the removal of devices and greatly improving the equipment's emergency handling capabilities. The upper and lower sliding components work together to provide stable sliding guidance for the smooth door frame and door from both ends, ensuring that the door can open and close smoothly under normal operating conditions.

[0020] The following will provide a more detailed description of the technical solution of a quick disengagement mechanism for a lateral sliding door after a malfunction, in conjunction with embodiments.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] like Figures 1 to 8 As shown, this embodiment of a lateral sliding door quick-release mechanism after a malfunction includes a housing frame 1, a smooth door outer frame 2, and a door 3 mounted on the smooth door outer frame 2. An upper sliding component 4 is provided between the upper end of the smooth door outer frame 2 and the housing frame 1, and a lower sliding component 5 is provided between the lower end of the smooth door outer frame 2 and the housing frame 1. A rack 6 is provided on the smooth door outer frame 2, and a reduction motor 7 is provided on the housing frame 1 corresponding to the inner side of the rack 6. A transmission gear 8, which meshes with the rack 6, is slidably mounted on the output shaft of the reduction motor 7, and the transmission gear 8 rotates under the drive of the reduction motor 7. An elastic support member 9 is provided on the output shaft for pushing outward and supporting the transmission gear 8. The door 3 can be installed on the smooth door outer frame 2 in any existing manner, as long as it can seal the opening of the housing after installation, fixation, and movement. Since this is not the technical problem to be solved in this application, it will not be described in detail. The upper sliding assembly 4 includes an upper guide rod 401 mounted on the housing frame 1 and multiple concave pulleys 402 rotatably connected to the upper end of the smooth door outer frame 2. The annular grooves of the concave pulleys 402 engage with the upper guide rod 401. The lower sliding assembly 5 includes a lower guide rod 501 mounted on the housing frame 1 and multiple sliders 502 mounted at the lower end of the smooth door outer frame 2. The sliders 502 are slidably connected to the lower guide rod 501. Specifically, the sliders 502 can be slidably connected to the lower guide rod 501 in any existing manner. A spline 10 is provided between the transmission gear 8 and the output shaft of the reduction motor 7. A gear baffle 11 is detachably connected to the outer end of the output shaft of the reduction motor 7. The elastic support 9 is a spring. A limit plate is provided on the output shaft of the reduction motor 7. The spring is sleeved on the output shaft of the reduction motor 7 between the transmission gear 8 and the limit plate.

[0023] Working principle: Under normal operating conditions, the geared motor 7 is powered on and drives the output shaft to rotate. The output shaft, connected via spline 10, drives the transmission gear 8 to rotate. The transmission gear 8 meshes with the rack 6 on the outer frame 2 of the sliding door, thereby driving the outer frame 2 and the door body 3 to slide laterally along the upper sliding assembly 4 and the lower sliding assembly 5, achieving normal opening and closing of the door body 3. At this time, the spring (i.e., the elastic support 9) is in a naturally extended state, providing outward support force to the transmission gear 8, ensuring stable meshing between the transmission gear 8 and the rack 6. When the equipment experiences a power outage or a drive mechanism malfunction, the operator manually pushes the transmission gear 8 inward. The transmission gear 8 slides inward against the spring force on the output shaft, disengaging from the rack 6. At this time, the smooth door frame 2 and the door body 3 are no longer restricted by the displacement of the transmission gear 8 and the rack 6. The operator can manually push the smooth door frame 2 to slide laterally along the upper guide rod 401 and concave pulley 402 of the upper sliding assembly 4, and the lower guide rod 501 and slider 502 of the lower sliding assembly 5, thereby opening the door body 3 and taking out the medical device inside the box. After the operation is completed, the transmission gear 8 is released, and under the action of the spring force, the transmission gear 8 automatically resets and restores its initial position relationship with the rack 6, preparing for normal use next time. With this structure, when the equipment loses power or the drive mechanism malfunctions, the operator can quickly disengage the transmission gear 8 from the rack 6 by pushing it inward on the output shaft, thus releasing the displacement restriction on the smooth door frame 2. This allows the smooth door frame 2 and door 3 to slide easily, opening the box and promptly removing the medical devices inside. This effectively solves the problem of existing equipment doors being sealed shut, preventing the removal of devices and greatly improving the equipment's emergency handling capabilities. The upper sliding component 4 and the lower sliding component 5 work together to provide stable sliding guidance for the smooth door frame 2 and door 3 from both ends, ensuring that the door 3 can open and close smoothly under normal working conditions. The transmission gear 8 is connected to the output shaft of the reduction motor 7 via a spline 10, and with the help of the gear baffle 11 and springs, it ensures stable transmission during normal operation and provides a reliable guarantee for rapid disengagement in case of malfunction.

[0024] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge or conventional technology in the field. Therefore, this utility model will not explain the control method and circuit connection in detail.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
