Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of components for negative pressure isolators, and in particular to a support frame for an isolator transfer tank and an isolator. Background Technology
[0002] Negative pressure isolators are widely used feeding equipment in high-level pathogenic microorganism laboratories and laboratory animal research fields, ensuring biosafety through physical isolation. The transfer container, as a key device within the negative pressure isolator for transferring items such as feed, tools, and laboratory animals, is used to transfer these items.
[0003] In actual use, the transfer drum needs to be docked with the negative pressure isolator and sealed by rotation. However, because the inside of the transfer drum is a smooth surface, the vibration generated during docking and the rotation during the connection will cause the position of the items placed in the transfer drum to change, and the items often slide to the middle and rear of the transfer drum.
[0004] For operators, especially those with limited arm length, it is difficult to reach items that have slipped into the back of the transfer bin. Current technology lacks effective solutions that neither prevent items from shifting during transfer nor facilitate easy retrieval of items deep within the transfer bin. This causes significant inconvenience in actual operation and affects work efficiency. Utility Model Content
[0005] The purpose of this utility model is to provide a support frame and isolator for a transfer bucket, so as to solve the problem that the items inside the transfer bucket are not easy to remove in the prior art.
[0006] To achieve the above objectives, this utility model provides the following solution: This utility model discloses a support frame for a transfer bucket of an isolator, including a hollow support frame body. The support frame body is used to hold the items to be transferred. The periphery of the support frame body is also provided with a protruding support bracket. All or part of the support bracket is used to slide in contact with the inner wall of the transfer bucket.
[0007] In one embodiment, the support bracket is in complete sliding contact with the inner wall of the transfer bucket.
[0008] As one embodiment, the support brackets are evenly distributed along the circumferential direction on at least one cross-section of the support frame body.
[0009] In one embodiment, the support bracket is in sliding contact with the inner wall of the transfer bucket and is concentric with the support frame body. The imaginary cylinder in contact with all the support brackets is the outer cylinder of the support frame. The difference between the diameter R2 of the outer cylinder and the inner diameter R1 of the transfer bucket is 0.2mm to 3mm.
[0010] As one embodiment, the protrusion height of the support bracket is 4mm~6mm.
[0011] As one embodiment, along the axial direction of the support frame body, the length dimension L2 of the support frame body is smaller than the length dimension L1 of the transfer bucket, and the difference between L1 and L2 is less than or equal to 20mm.
[0012] In one embodiment, the support frame body includes two semi-circular brackets, the planar ends of the two semi-circular brackets abutting each other to form a cylindrical bracket, and the planar ends of the two semi-circular brackets slidingly engaging.
[0013] As one embodiment, the semi-circular bracket includes two arc-shaped segments and one or more support rods connecting the two arc-shaped segments, with the support rods disposed on the circumferential outer side of the arc-shaped segments.
[0014] As one embodiment, the diameter of the support rod is 7~9mm.
[0015] This utility model also discloses an isolator, including an isolator body, a transfer bucket, and a support frame. The transfer bucket is detachably connected to the isolator body, and the support frame makes point contact with the inner wall of the transfer bucket through the support bracket. When the transfer bucket rotates, the support frame and the transfer bucket rotate relative to each other.
[0016] The present invention achieves the following technical advantages over the prior art: This invention features a support bracket on the periphery of the support frame, creating point contact between the support frame and the inner wall of the transfer container. This significantly reduces frictional resistance. When the transfer container vibrates and rotates during docking and rotation, the support frame does not rotate continuously with the container but remains relatively stationary or rotates slightly, effectively preventing items placed on the support frame from slipping into the rear of the transfer container. Furthermore, because the items maintain their relative position on the support frame during transfer, operators can easily pull out the support frame along with the items on it, facilitating the retrieval of the items to be transferred. This advantage is particularly pronounced for items that have slipped into the rear of the transfer container. Moreover, the point contact structure formed by the support bracket reduces the contact area between the items and the transfer container. After the experiment, when staff introduce vaporized disinfectants such as hydrogen peroxide or peracetic acid into the transfer container through the rear interface, the disinfectant gas can fully contact the contaminated items, ensuring disinfection effectiveness and meeting the relevant requirements for high-level pathogenic microorganism laboratory disinfection.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] The purpose of this utility model is to provide a support frame and isolator for a transfer bucket, so as to solve the problem that the items inside the transfer bucket are not easy to remove in the prior art.
[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0022] like Figures 1-12 As shown, this utility model discloses a support frame for a transfer bucket of an isolator, including a hollow support frame body 1. The support frame body 1 is used to hold the items to be transferred. The outer periphery of the support frame body 1 is also provided with a protruding support bracket 3. All or part of the support bracket 3 is used to slide in contact with the inner wall of the transfer bucket 2. By setting a support bracket 3 around the support frame body 1, the support bracket 3 makes point contact between the support frame and the inner wall of the transfer bucket 2, greatly reducing the frictional resistance between the two. When the transfer bucket 2 vibrates and rotates during docking and rotation, the support frame will not rotate with the transfer bucket 2 continuously, but will remain relatively stationary or rotate slightly, thus effectively preventing items placed on the support frame from slipping into the rear of the transfer bucket 2. Moreover, since the items can maintain their relative position on the support frame during the transfer process, the operator can easily pull out the support frame along with the items on it by removing the support frame, making it convenient to retrieve the items to be transferred. This advantage is particularly obvious for items that have slipped into the rear of the transfer bucket 2. Furthermore, the point contact structure formed by the support bracket 3 reduces the contact area between the items and the transfer bucket 2. When the staff introduces hydrogen peroxide or peracetic acid, etc., into the transfer bucket 2 through the tail port after the experiment, the disinfecting gas can fully contact the contaminated items, ensuring the disinfection effect and improving the effectiveness of disinfection, thereby meeting the relevant requirements for disinfection in high-level pathogenic microorganism laboratories.
[0023] Preferably, the support frame body 1 is integrally formed and made of stainless steel. Stainless steel can withstand the corrosion of disinfectants such as hydrogen peroxide, which ensures both structural strength and ease of cleaning and disinfection.
[0024] In one embodiment, the support 3 is in full sliding contact with the inner wall of the transfer bucket 2.
[0025] As one embodiment, support brackets 3 are evenly distributed along the circumferential direction on the cross-section of at least one support frame body 1.
[0026] Preferably, the support brackets 3 are evenly distributed along the axial and / or circumferential directions of the support frame body 1, so that the support frame always maintains a stable relative position in the transfer barrel 2 and will not be violently displaced due to the rotation of the transfer barrel 2.
[0027] Preferably, the support brackets 3 are arranged in an alternating pattern along the axial direction of the support frame, which not only enhances the stability of the support but also avoids the formation of a continuous friction track on the inner wall of the transfer barrel 2.
[0028] In one embodiment, the support bracket 3 partially slides in contact with the inner wall of the transfer bucket 2 and is concentric with the support frame body 1. The imaginary cylinder that contacts all the support brackets 3 is the outer cylinder of the support frame. The difference between the diameter R2 of the outer cylinder and the inner diameter R1 of the transfer bucket 2 is 0.2mm to 3mm.
[0029] It is understandable that the inner diameter R1 of the transfer bucket 2 and the outer cylindrical tube R2 can be equal or form a certain clearance fit, which can ensure that the support frame will not fall out of the transfer bucket 2 after the support frame is pulled out, and also ensure the smoothness of relative rotation.
[0030] Preferably, the inner diameter R1 of the transfer bucket 2 is set to 342mm, and the diameter R2 of the outer cylindrical tube is set to 340mm.
[0031] As one implementation, the protrusion height of the support bracket 3 is 4mm to 6mm. By setting the height of the support bracket 3 to 4mm to 6mm, sufficient support clearance is ensured while avoiding the problem of unstable swaying of the support frame within the transfer bucket 2 due to excessive clearance.
[0032] Preferably, the protrusion height of the support bracket 3 is 5mm.
[0033] Preferably, the support bracket 3 is a hemispherical protrusion structure with a polished outer surface to effectively reduce the sliding resistance with the inner wall of the transfer barrel 2.
[0034] In one embodiment, along the axial direction of the support frame body 1, the length dimension L2 of the support frame body 1 is smaller than the length dimension L1 of the transfer bucket 2, and the difference between L1 and L2 is less than or equal to 20mm. This dimensional relationship ensures that the support frame can provide sufficient bearing area and is easy to pull out from the transfer bucket 2. Operators can easily pull the support frame part out of the transfer bucket 2 to easily retrieve items located deep inside.
[0035] Preferably, the difference between L1 and L2 is 15~20mm.
[0036] Preferably, the length L2 of the support frame body 1 is set to 463mm, the length L1 of the transfer bucket 2 is 483mm, and the support frame body 1 has a clear visual mark along the axial direction at a distance of 150mm from the end to indicate the maximum pull-out limit to the operator. The maximum pull-out limit of 150mm will not reduce the bearing area due to being too short, nor will it affect the pull-out operation due to being too long.
[0037] Preferably, the two ends of the support frame body 1 are provided with anti-slip textures to facilitate the operator's gripping and pulling.
[0038] As one embodiment, the support frame body 1 includes two semi-circular brackets. The flat ends of the two semi-circular brackets abut each other to form a cylindrical bracket. The flat ends of the two semi-circular brackets slide together along the axial direction of the support frame body 1. This split design allows the item to be retrieved by simply pulling out the lower semi-circular bracket when the support frame is pulled out. The upper semi-circular bracket will not obstruct the operator's arm.
[0039] Preferably, the flat end is provided with a mutually cooperating snap-fit structure to ensure that the two semi-circular brackets are securely connected.
[0040] As one embodiment, the semi-circular bracket includes two arc-shaped segments 5 and one or more support rods 4 connected between the two arc-shaped segments 5. The support support 3 is located on the circumferential outer side of the arc-shaped segments 5. This structural design not only ensures the overall strength of the support frame, but also ensures the stability of the items placed, and facilitates cleaning and disinfection.
[0041] Preferably, the support bracket 3 is correspondingly disposed at both ends of the support rod 4.
[0042] As one implementation method, the diameter of the support rod 4 is 7~9mm, which ensures sufficient load-bearing strength and avoids misalignment between the two semi-circular support frames.
[0043] Preferably, the surface of the support rod 4 is provided with an anti-slip coating to reduce the slippage of items during the transfer process.
[0044] Preferably, five support brackets 3 are provided on each arc segment 5 of each semi-circular bracket, for a total of 15 support brackets 3, to ensure that the support frame is subjected to uniform force.
[0045] This utility model also discloses an isolator, including an isolator body, a transfer bucket 2 and a support frame. The transfer bucket 2 is detachably connected to the isolator body. The support frame makes point contact with the inner wall of the transfer bucket 2 through a support bracket 3. When the transfer bucket 2 rotates, the support frame and the transfer bucket 2 rotate relative to each other.
[0046] Preferably, the inner wall of the transfer barrel 2 is mirror polished to further reduce the coefficient of friction between the inner wall of the transfer barrel 2 and the support bracket 3.
[0047] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
