Description

Technical Field

[0001] This application relates to the technical field of medical device manufacturing equipment, and in particular to an adjustable bridging device for sterilization cabinets. Background Technology

[0002] In the medical device manufacturing industry, finished products often require overall or whole-box sterilization, a process that relies on large sterilization cabinets. Due to the extreme weight of these devices, installation requires pre-excavating a trench in the ground and pouring a concrete base before placing the sterilization cabinet inside. Because the trench is typically larger than the cabinet body, a gap exists between the cabinet door and the ground.

[0003] To facilitate the smooth entry and exit of goods, a loading device must be installed at the doorway. The core of this device is a rotatable ramp driven by a cylinder. When goods enter or exit, the ramp rotates and lowers, overlapping the door threshold to form a passageway; before closing the door, the ramp returns to its original position to avoid obstruction.

[0004] However, existing mounting devices have significant drawbacks. They are fixedly installed at the door of a specific sterilization cabinet, and the extension length of their mounting plates is fixed and non-adjustable. In actual warehouses, due to slight differences in installation conditions and slot dimensions, the horizontal distance between the front edge of the door and the edge of the slot on the ground often varies among multiple sterilization cabinets. It is this difference in horizontal distance that makes mounting devices designed for a particular location unsuitable for other cabinets. Once a device fails, it cannot be quickly replaced with a spare part, requiring downtime for repairs. This not only significantly increases maintenance costs and equipment downtime but also inconveniences continuous production scheduling, ultimately hindering the improvement of overall sterilization efficiency. Utility Model Content

[0005] To address the problem that existing mounting devices are fixed and the non-adjustable length of the mounting plate makes them unsuitable for varying horizontal distances between the doorway of different sterilizers and the edge of the floor groove, this application provides an adjustable bridging device for sterilizers.

[0006] The adjustable bridging device for sterilizers provided in this application adopts the following technical solution: An adjustable bridging device for a sterilizer includes a support assembly, a mounting assembly, and a drive assembly. The support assembly includes a mounting plate, and the mounting assembly includes a mounting support frame, a length adjustment frame, and a height adjustment component. The mounting plate is detachably mounted on the floor, the mounting support frame is mounted on the mounting plate, the length adjustment frame is slidably mounted on the mounting support frame, and the height adjustment component is mounted on the length adjustment frame. The height adjustment component supports the length adjustment frame. The drive assembly is detachably mounted on one side of the mounting support frame, and the drive assembly is used to drive the mounting support frame to rotate.

[0007] By adopting the above technical solution, the mounting plate of the support component is detachably connected to the floor via mounting rods, enabling rapid deployment and disassembly of the device and facilitating flexible installation in different sterilizer locations. The mounting support frame achieves rotational movement through rotating support components, allowing the bridging device to adapt to the opening and closing of the sterilizer door. The length adjustment bracket adjusts the horizontal extension length via sliding adjustment, addressing the issue of varying horizontal distances between the sterilizer doorway and the floor groove edge. The height adjustment component provides stable support through vertical adjustment, adapting to different groove depths and ensuring reliable contact between the bridging device and the groove bottom. The drive component is detachable, facilitating maintenance and replacement and improving the flexibility of the device's use.

[0008] Preferably, the drive assembly includes an electric push rod, one end of which is disposed on the bottom of the groove, and the other end of which is disposed on the mounting support frame.

[0009] By adopting the above technical solution, the electric push rod serves as the driving source, and the telescopic movement is realized through the control circuit, thereby controlling the rotation angle of the support frame. This ensures that the platform can be accurately lowered to the door of the sterilizer to form a passage, and smoothly reset after the goods pass through, thus improving the stability and accuracy of the device operation.

[0010] Preferably, the mounting support frame is provided with a first spring pin, and the length adjustment frame is also provided with a plurality of first positioning holes; the first spring pin is used to position the length adjustment frame on the mounting support frame.

[0011] By adopting the above technical solution, the first spring pin cooperates with multiple first positioning holes to achieve multi-level positioning of the length adjustment frame on the mounting support frame, ensuring the accuracy and stability of the horizontal length adjustment and adapting to the changes in the horizontal distance between the door of different sterilizers and the edge of the ground groove.

[0012] Preferably, the height adjusting component includes an adjusting support rod and an adjusting telescopic rod. The adjusting support rod is slidably mounted on the length adjusting frame and is provided with a second spring pin for positioning the adjusting support rod on the length adjusting frame. The adjusting telescopic rod is slidably mounted on the adjusting support rod and is also provided with a third spring pin. The adjusting telescopic rod is provided with multiple second positioning holes, and the third spring pin is used to position the adjusting telescopic rod on the adjusting support rod.

[0013] By adopting the above technical solution, the height adjustment component adjusts the horizontal position of the support point by adjusting the horizontal sliding of the support rod on the length adjustment frame, combined with the positioning of the second spring pin and the first positioning hole. By adjusting the vertical extension and retraction of the telescopic rod within the support rod, combined with the cooperation of the third spring pin and multiple second positioning holes, multi-level precise adjustment of the support height is achieved. This dual adjustment mechanism allows the device to adapt to different trench depths, ensuring reliable contact between the end of the telescopic rod and the trench bottom, providing stable vertical support for the bridging device. Simultaneously, the cooperation structure of the spring pin and positioning holes facilitates operation, improving the convenience of adjustment and the reliability of positioning.

[0014] Preferably, the mounting support frame is provided with a mounting support plate, and the length adjustment frame is provided with an adjustment plate, the adjustment plate being slidably mounted on the mounting support plate.

[0015] By adopting the above technical solution, the support plate and the adjustment plate are connected by sliding to form a continuous platform surface, ensuring that goods pass smoothly when entering and exiting the sterilization cabinet.

[0016] Preferably, the mounting support frame is rotatably mounted on the mounting plate via a rotating support member.

[0017] By adopting the above technical solution, the rotating support provides a stable fulcrum for the mounting support frame, enabling the mounting assembly to achieve smooth rotational movement under the action of the drive assembly. This rotating connection structure ensures that the mounting plate can be lowered to the working position during use and can be rotated to the retracted position in a timely manner during non-use periods, avoiding obstruction of the sterilizer door closing operation and ensuring the normal operation of the sterilizer.

[0018] Preferably, the rotating support includes a rotating rod and an anti-detachment sleeve. The rotating rod is inserted into the mounting plate and the mounting support frame. The anti-detachment sleeve is fitted onto the rotating rod and is provided with an anti-detachment spring pin. The anti-detachment sleeve is used to position the rotating rod on the mounting plate and the mounting support frame.

[0019] By adopting the above technical solution, the rotating rod and the anti-detachment sleeve form a detachable rotating connection, which facilitates installation and disassembly. At the same time, the anti-detachment spring pin prevents the rotating rod from accidentally falling off, improving the safety and reliability of the device and facilitating maintenance and operation.

[0020] Preferably, the support assembly further includes a feeding support plate, which is disposed on the mounting plate.

[0021] By adopting the above technical solution, the feed support plate smoothly transitions the height difference between the goods and the mounting plate through its inclined design, avoiding obstruction of the goods by the mounting plate during the entry and exit process, improving the efficiency of goods passage, and reducing the risk of jamming.

[0022] In summary, this application includes the following beneficial technical effects: The mounting plate and rod of the support component enable quick installation and disassembly. The length adjustment frame of the mounting component allows for horizontal length adjustment through the engagement of the first spring pin and the first positioning hole. The height adjustment component allows for vertical height adjustment through the sliding and positioning of the adjustment support rod and the adjustment telescopic rod, thus accommodating differences in the horizontal distance and groove depth between the doorway and the ground edge of different sterilizers. The electric push rod of the drive component drives the rotation of the mounting support frame, realizing the automatic lowering and resetting of the bridging device. Most components are detachable, facilitating individual component replacement, improving maintenance efficiency, reducing equipment downtime, and enhancing the versatility between multiple sterilizers.

[0029] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0030] This application discloses an adjustable bridging device for a sterilization cabinet, referring to... Figure 1It includes a support component 1, a mounting component 2, and a drive component 3. The support component 1 is mounted on the floor, the mounting component 2 is mounted on the support component 1, one end of the drive component 3 is mounted on the bottom of the groove, and the other end of the drive component 3 is mounted on the mounting component 2. The drive component 3 is used to drive the mounting component 2 to deflect.

[0031] Reference Figures 1-3 The support assembly 1 includes a mounting plate 11, a mounting rod 12, and a feeding support plate 13. Specifically, in this embodiment, two mounting rods 12 are provided, and the two mounting plates 11 are respectively installed on both sides of the feeding support plate 13 along its long axis. The mounting rods 12 are used to fix the mounting plates 11 to the floor. A rotating handle 121 is fixedly connected to the upper end of the mounting rod 12, and the lower end of the mounting rod 12 is a cone. A helical rod is machined between the cone of the mounting rod 12 and the rotating handle 121. With this structure, the cone of the mounting rod 12 can easily break through the surface of the floor, the helical rod can easily screw the mounting rod 12 downward from the floor surface, and the rotating handle 121 can easily rotate the mounting rod 12, thereby achieving stable installation of the support assembly 1.

[0032] Reference Figure 1 , Figure 3 and Figure 4 The feeding support plate 13 is rotatably connected to the side of the mounting plate 11 away from the sterilizer 4 via a rotating support member 14. The rotating support member 14 includes a rotating insert rod 141 and an anti-detachment sleeve 142. The rotating insert rod 141 is used to position the feeding support plate 13 on the mounting plate 11, and the anti-detachment sleeve 142 is used to position the rotating insert rod 141 on both the mounting plate 11 and the feeding support plate 13. Specifically, the anti-detachment sleeve 142 is sleeved on the rotating insert rod 141, and an anti-detachment spring pin 1421 is fixedly connected to the anti-detachment sleeve 142. The rotating insert rod 141 has an insertion hole for the anti-detachment spring pin 1421 to be inserted into. The anti-detachment spring pin 1421 is used to position the anti-detachment sleeve 142 on the rotating insert rod 141. In this embodiment, the feeding support plate 13 is inclined upward from the side away from the mounting plate 11 to the side closer to the mounting plate 11. The purpose of this inclined design is that, since the mounting plate 11 has a certain thickness, in order to avoid the mounting plate 11 from obstructing the entry and exit of goods during the feeding process, by setting the inclined structure of the feeding support plate 13, the height difference between the goods and the mounting plate 11 can be smoothly transitioned, ensuring that the goods pass through smoothly.

[0033] Reference Figures 2-3The mounting component 2 includes a mounting support frame 21, a length adjustment frame 22, and a height adjustment component 23. The mounting support frame 21 is also rotatably connected to the mounting plate 11 via a set of rotating support components 14, and the mounting support frame 21 is rotatably connected to the side of the mounting plate 11 closest to the sterilizer 4. The specific structure of the rotating support component 14 here is the same as that of the rotating support component 14 connecting the feed support plate 13 and the mounting plate 11 mentioned above. A first sliding groove 213 is provided at the end of the mounting support frame 21 away from the mounting plate 11, and the length adjustment frame 22 is slidably connected to the mounting support frame 21 via the first sliding groove 213. A mounting support plate 211 is fixedly connected to the upper end of the mounting support frame 21. A second sliding groove 2111 is provided at the end of the mounting support plate 21 away from the mounting plate 11. An adjustment plate 221 is fixedly connected to the length adjustment frame 22. The end of the adjustment plate 221 away from the mounting plate 11 is fixedly connected to the length adjustment frame 22. The other end of the adjustment plate 221 is slidably connected to the mounting support plate 211 through the second sliding groove 2111.

[0034] Reference Figure 3 A first spring pin 212 is fixedly connected to the side wall of the support frame 21 at the end away from the mounting plate 11. A row of first positioning holes 223 is opened on one side wall of the length adjustment frame 22 along its own length direction. The length adjustment frame 22 is positioned on the support frame 21 by the first spring pin 212 and the first positioning holes 223. Reference Figure 2 , Figure 3 and Figure 5 The height adjustment component 23 includes an adjustment support rod 231 and an adjustment telescopic rod 232. One end of the adjustment support rod 231 has a connecting groove 2311, the axis of which is perpendicular to the length direction of the length adjustment frame 22. The adjustment support rod 231 is slidably connected to the length adjustment frame 22 via the connecting groove 2311. A second spring pin 2312 is fixedly connected to one side wall of the connecting groove 2311. In this embodiment, the second spring pin 2312 shares a row of first positioning holes 223 with the first spring pin 212. The adjustment support rod 231 is positioned on the length adjustment frame 22 via the second spring pin 2312 and the first positioning holes 223, and the length direction of the length adjustment frame 22 is perpendicular to the length direction of the adjustment support rod 231. The other end of the adjusting support rod 231 has a third sliding groove 2314. A third spring pin 2313 is fixedly connected to one side wall of the end of the adjusting support rod 231 away from the length adjusting frame 22. The adjusting telescopic rod 232 is slidably connected to the adjusting support rod 231 through the third sliding groove 2314. A row of second positioning holes 2321 is opened on one side wall of the adjusting telescopic rod 232 along its own length direction. The adjusting telescopic rod 232 is positioned on the adjusting support rod 231 through the third spring pin 2313 and the second positioning holes 2321. The end of the adjusting telescopic rod 232 contacts the bottom of the groove.

[0035] Reference Figures 2-3 The drive assembly 3 includes an electric push rod 32 and a drive support plate 31. A drive connecting rod 214 is fixedly connected to one side wall of the support plate 211, and the length direction of the drive connecting rod 214 is perpendicular to the length direction of the support plate 211. In this embodiment, the drive support plate 31 is mounted on the bottom of the groove via a mounting rod 12. The end of the electric push rod 32 is rotatably connected to the drive support plate 31 via bolts. A sleeve 321 is fixedly connected to the end of the piston rod of the electric push rod 32, and the sleeve 321 is fitted onto the drive connecting rod 214. The specific structure of the mounting rod 12 here is the same as that of the mounting rod 12 that fixes the mounting plate 11 to the floor in the aforementioned support assembly 1. When it is necessary to disassemble the electric push rod 32, the bolts connecting the electric push rod 32 and the drive support plate 31 can be removed first, and then the sleeve 321 can be slid out axially along the drive connecting rod 214 to complete the disassembly operation.

[0036] Reference Figures 2-4 In this embodiment, the mounting plate 11 is detachably connected to the floor via the mounting rod 12. The feeding support plate 13 and the mounting support plate 211 are detachably connected to the mounting plate 11 via a set of rotating support members 14. The length adjustment frame 22 is detachably connected to the mounting support frame 21 via the first spring pin 212 and the first positioning hole 223. The adjusting support rod 231 is detachably connected to the length adjustment frame 22 via the second spring pin 2312 and the first positioning hole 223. The adjusting telescopic rod 232 is detachably connected to the adjusting support rod 231 via the third spring pin 2313 and the second positioning hole 2321. The drive support plate 31 is detachably connected to the bottom of the groove via the mounting rod 12. The electric push rod 32 is detachably connected to the mounting support plate 211 and the drive support plate 31 via bolts and sleeves 321. The purpose of adopting the above-mentioned detachable connection method is to facilitate the individual replacement of a component when it is damaged, thereby improving the convenience of maintenance operations. Meanwhile, in situations where multiple bridging devices are used in conjunction, if a component of one device is damaged, the corresponding intact component can be directly removed from another device for replacement without disassembling the entire bridging device, thereby improving the versatility of components and the efficiency of replacement.

[0037] The implementation principle of the adjustable bridging device for a sterilizer according to this application embodiment is as follows: When the adjustable bridging device of this application embodiment is working, the electric push rod 32 of the drive assembly 3 pushes the drive connecting rod 214, causing the mounting assembly 2 to deflect around the rotating support member 14. When goods need to enter or exit the sterilizer 4, the electric push rod 32 retracts, causing the mounting support frame 21 to rotate downwards, so that the bridging plate formed by the mounting support plate 211 and the length adjustment frame 22 is lowered and overlaps at the door of the sterilizer 4, forming a smooth passage. After the goods pass through, the electric push rod 32 extends, driving the mounting assembly 2 to return to its original position, avoiding obstruction of the closing of the sterilizer 4.

[0038] This application utilizes a length adjustment bracket 22 to slide within the first slide groove 213 to adjust the extension length of the mounting plate. The first spring pin 212, in conjunction with a row of first positioning holes 223, is used to fix the position, adapting to differences in the horizontal distance between the doorway of the sterilizer 4 and the edge of the groove on the ground. The adjusting support rod 231 of the height adjustment component 23 slides on the length adjustment bracket 22 via a connecting slide groove 2311. The adjusting telescopic rod 232 moves within the third slide groove 2314 and is positioned by the third spring pin 2313 and the second positioning hole 2321, ensuring the end of the adjusting telescopic rod 232 contacts the bottom of the groove, adapting to different groove depths. The mounting rod 12 of the support assembly 1 is quickly fixed by screwing into the floor. The inclined design of the feeding support plate 13 smoothly transitions the height difference between the goods and the mounting plate 11. Most components are detachable, allowing for individual replacement when damaged, improving maintenance efficiency, reducing equipment downtime, enhancing the versatility between multiple sterilizers 4, and thus optimizing the overall scheduling of sterilization operations.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
