Abstract
Description
Technical Field
[0001] This utility model relates to the field of temporary partition technology, and in particular to a single-channel opening and closing isolation device. Background Technology
[0002] Single-channel opening and closing isolation devices primarily achieve the separation of two spaces through physical barriers, with isolation curtains being a common choice due to their lightweight and flexibility. In existing technologies, opening structures are typically incorporated into the isolation curtain to enable opening and closing of the passage. The current mainstream single-channel partition solution employs a double-zipper design, where two long zippers are installed parallel to each other on the same plane of the isolation curtain, forming an openable passage area. In practice, the user needs to simultaneously pull both parallel zippers, roll up the curtain between the zippers, and then use the sharp end of a metal hook to pierce and secure the rolled-up curtain, thus creating a passage for people or goods. While this design achieves the passage function, it requires two parallel zippers, increasing material costs and operational steps. Furthermore, the sharp end of the metal hook poses a risk of injuring the operator, and the curtain-fixing process relies on precise piercing of the curtain by the hook, usually requiring the coordinated use of both hands. In addition, because the zipper spacing is fixed, the size of the resulting passage opening cannot be adjusted according to actual needs. Utility Model Content

[0017] In an optional embodiment, the first support rod includes a plurality of first connecting rods connected in sequence, and at least one pair of adjacent first connecting rods are connected by a first adjusting member, which is used to adjust the relative position of the adjacent first connecting rods.
[0018] And / or, the second support rod includes multiple segments of second connecting rods connected in sequence, and a second adjusting member is connected between any two adjacent segments of the second connecting rods.

[0038] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.
[0039] This embodiment provides a single-channel opening and closing isolation device, such as... Figure 1 and Figure 2 As shown, it includes a support rod assembly 1, an isolation layer 2, a connecting assembly 3, and an adhesive assembly 4;
[0040] The two sides of the isolation layer 2 are connected to the support rod assembly 1;
[0041] The connecting component 3 is connected to the isolation layer 2, and the connecting component 3 extends vertically to the bottom end of the isolation layer 2;
[0042] The adhesive assembly 4 includes a first adhesive member 41 and a second adhesive member 42 for detachable connection with the first adhesive member 41. Both the first adhesive member 41 and the second adhesive member 42 are detachably connected to the isolation layer 2. The first adhesive member 41 is located on the edge of the isolation layer 2 near the connecting assembly 3, and the second adhesive member 42 is higher than the first adhesive member 41 and located on the side of the first adhesive member 41 away from the connecting assembly 3.
[0043] In use, the bottom end of the support rod assembly 1 can rest against the ground 6, and the top end of the support rod assembly 1 can rest against the ceiling 5, as shown. Figure 3 As shown, the user can lift the isolation layer 2 using the connecting component 3, and finally connect the first adhesive piece 41 and the second adhesive piece 42 to form a passage for the user. When it is necessary to close the passage, as... Figure 2 As shown, the connection between the first adhesive 41 and the second adhesive 42 is canceled. Under the action of gravity, the isolation layer 2 is vertically downward, the channels are merged, and the isolation layer 2 is closed by the connecting component 3, forming a closed surface again.
[0044] In the single-channel opening and closing isolation device provided in the above embodiment, only one connecting component is needed to work with the adhesive component 4 to realize the opening and closing of the channel, reducing material costs and operation steps, providing high safety and allowing operation with one hand. Since the first adhesive component 41 and the second adhesive component 42 are both detachably connected to the isolation layer 2, the size of the channel opening can be adjusted by the user according to actual needs.
[0045] The isolation layer 2 can be made of flexible waterproof materials such as plastic, specifically polyvinyl chloride (PVC), polyurethane (PU) coated fabric or other composite materials with barrier properties.
[0046] There are various optional forms of the connecting component 3. For example, the connecting component 3 includes a sub-zipper, a female zipper, and a zipper head 31. The sub-zipper and the female zipper extend vertically to the bottom of the isolation layer 2. The zipper head 31 is connected between the sub-zipper and the female zipper and is used to open and close the isolation layer 2. When the isolation layer 2 is in a closed state, the zipper head 31 is located at the bottom of the isolation layer 2.
[0047] For example, the connecting component 3 includes a first adsorption strip and a second adsorption strip. The first adsorption strip and the second adsorption strip extend vertically to the bottom of the isolation layer 2. The first adsorption strip and the second adsorption strip are magnetically attracted to each other, thereby realizing the opening and closing of the isolation layer 2.
[0048] Of course, the connecting component 3 is not limited to the two examples above; any structure that can enable the opening and closing of the isolation layer 2 is acceptable.
[0049] The first adhesive component 41 and the second adhesive component 42 can be detachably connected by means of hooks, magnetism, etc.
[0050] In alternative implementations, such as Figure 4 As shown, the first adhesive component 41 includes a female hook and loop fastener 411 and a first adhesive backing layer 412 connected to the female hook and loop fastener 411. The first adhesive backing layer 412 is bonded to the release layer 2.
[0051] When installing the above-mentioned isolation device, the user can stick the first adhesive layer 412 to a suitable position on the isolation layer 2 so that the user can connect the female Velcro 411 to the second adhesive 42.
[0052] The first adhesive element 41 is in the form of Velcro. When it is necessary to open the channel, simply press the female Velcro 411 onto the second adhesive element 42. The operation is convenient and simple. After long-term use, the bonding between the first adhesive layer 412 and the isolation layer 2 can be removed, and a new first adhesive element 41 can be replaced.
[0053] Specifically, the distance between the first adhesive component 41 and the bottom end of the support rod assembly 1 is 1.4m-1.6m.
[0054] When using, such as Figure 1 As shown, the height of the first adhesive component 41 is basically aligned with the shoulder of the human body, making it convenient for the user to pick up the first adhesive component 41 and connect it with the second adhesive component 42.
[0055] Specifically, the distance between the first adhesive component 41 and the bottom end of the support rod assembly 1 can be 1.4m, 1.45m, 1.5m, 1.55m or 1.6m.
[0056] Based on the above implementation methods, such as Figure 3 As shown, the second adhesive component 42 includes a sub-hook and loop fastener 421 and a second adhesive backing layer 422 connected to the sub-hook and loop fastener 421. The second adhesive backing layer 422 is bonded to the release layer 2.
[0057] When installing the above-mentioned isolation device, the user can attach the second adhesive layer 422 to a suitable position on the isolation layer 2 to control the size of the formed channel opening.
[0058] When in use, since the female hook and loop fastener 411 has a rough surface and the male hook and loop fastener 421 has a hook surface that can hook onto the rough surface, pressing the female hook and loop fastener 411 onto the male hook and loop fastener 421 will open the channel. Applying external force to release the adhesion between the female hook and loop fastener 411 and the male hook and loop fastener 421 will allow the isolation layer 2 to fall.
[0059] In an optional embodiment, two adhesive components 4 are configured, with the two adhesive components 4 located on both sides of the connecting component 3, respectively.
[0060] Users can use the two adhesive components 4 to lift the isolation layer 2 to both sides, so that the channel can expose a sufficiently large area.
[0061] Of course, when the area of the isolation layer 2 is large, in order to keep the isolation layer 2 stably open, multiple adhesive components 4 can also be provided on each side of the connecting component 3.
[0062] In an optional embodiment, the adhesive assembly 4 includes one first adhesive member 41 and at least one second adhesive member 42. When only one second adhesive member 42 is configured, the channel has a fixed size after the first adhesive member 41 and the second adhesive member 42 are connected.
[0063] When multiple second adhesive members 42 are configured, such as Figure 5 As shown, each of the second adhesive members 42 gradually moves away from the first adhesive member 41 in the horizontal direction, and as the distance between the second adhesive member 42 and the first adhesive member 41 in the horizontal direction increases, the height of the second adhesive member 42 becomes higher.
[0064] The above implementation can be understood as follows: the second adhesive 42 closest to the first adhesive 41 is located at a relatively low position, while the second adhesive 42 farther from the first adhesive 41 is located at a higher position.
[0065] In use, the user can bond the first adhesive 41 to a suitable second adhesive 42. When bonded to the nearest second adhesive 42, the opening of the channel is the smallest, and when bonded to the farthest second adhesive 42, the opening of the channel is the largest. The user can adjust the size of the channel opening according to factors such as the flow of people, making it more flexible to use.
[0066] Furthermore, by controlling the height variation of the second adhesive member 42 at different positions, the above-described embodiment can optimize the tension distribution of the isolation layer 2 during unfolding. Specifically, when the user attaches the mother hook and loop fastener 411 to the daughter hook and loop fasteners 421 at different positions, the isolation layer 2 naturally forms a corresponding tilt angle due to the different degrees of unfolding, thereby preventing wrinkles or local collapse of the isolation layer 2 in the unfolded state and ensuring the flatness and stability of the channel opening.
[0067] In alternative implementations, such as Figure 6 As shown, the first bottom 23 of the isolation layer 2 located on one side of the connecting component 3 is provided with a first drawstring 21, which is used to tighten the first bottom 23; the second bottom 24 of the isolation layer 2 located on the other side of the connecting component 3 is provided with a second drawstring 22, which is used to tighten the second bottom 24.
[0068] After the first adhesive component 41 is connected to the second adhesive component 42, the first bottom 23 and the second bottom 24 hang down naturally. To prevent pedestrians from rubbing against the first bottom 23 and the second bottom 24 when passing through the passage, which would cause the first adhesive component 41 and the second adhesive component 42 to bear a large pulling force, the user can tighten the first bottom 23 with the first drawstring 21 and tighten the second bottom 24 with the second drawstring 22, thereby expanding the size of the bottom opening of the passage and improving the stability and practicality of the isolation structure.
[0069] In addition, such as Figure 7 As shown, a third drawstring 25 may also be provided on the isolation layer 2. One end of the third drawstring 25 is located near the first adhesive member 41, and the other end of the third drawstring 25 is located near the second adhesive member 42.
[0070] After the first adhesive part 41 is connected to the second adhesive part 42, the user can tighten the third drawstring 25 to make the top of the passage wide enough for pedestrians to pass through.
[0071] To facilitate the installation of the drawstrings, the part of the isolation layer 2 with the drawstrings can adopt a double-layer structure, with the drawstrings located between the double-layer structure.
[0072] Of course, the first drawstring 21, the second drawstring 22 and the third drawstring 25 mentioned above can also be replaced with Velcro.
[0073] In an optional embodiment, the distance between the top end of the connecting component 3 and the bottom end of the support rod assembly 1 is 2m-2.2m.
[0074] The above-described embodiment allows the top of the connecting component 3 to be positioned at approximately the height of a person's raised hands, making it easy for the user to pull the zipper head 31 to the top.
[0075] Specifically, the distance between the top of the connecting component 3 and the bottom of the support rod group 1 is 2m, 2.05m, 2.1m, 2.15m or 2.2m.
[0076] In alternative implementations, such as Figure 8 As shown, the support rod assembly 1 includes a first support rod 11 and a second support rod 12, both of which are telescopic along their own extension direction.
[0077] The extension and retraction adjustment of the first support rod 11 and the second support rod 12 can be carried out independently, so that the support rod assembly 1 can adapt to the support requirements of different heights, ensuring that the support rod assembly 1 can be stably placed between the ceiling 5 and the ground 6.
[0078] In alternative implementations, such as Figure 8 As shown, the first support rod 11 includes multiple first connecting rods 111 connected in sequence, and at least one pair of adjacent first connecting rods 111 is connected by a first adjusting member, which is used to adjust the relative position of the adjacent first connecting rods 111. The second support rod 12 includes multiple second connecting rods 121 connected in sequence, and any two adjacent second connecting rods 121 are connected by a second adjusting member, which is used to adjust the relative position of the adjacent second connecting rods 121.
[0079] The following uses the first support rod 11 as an example to explain the length adjustment process in detail:
[0080] The two first connecting rods 111 connected by the first adjusting component can be fitted together. The first adjusting component can be a bolt, with an oblong hole on the outer first connecting rod 111 and a circular threaded hole on the inner first connecting rod 111. The bolt can pass through the oblong hole and the circular threaded hole to connect, and the length of the first supporting rod 11 can be adjusted by adjusting the tightening of the bolt. Of course, the first adjusting component can also be adjusted by using a snap-fit and slot engagement to achieve the length adjustment of the first supporting rod 11. In summary, there are various structures that can achieve the length adjustment of the first supporting rod 11, which will not be listed here.
[0081] The adjustment process of the second support rod 12 is similar, and will not be described in detail here to save space.
[0082] In alternative implementations, such as Figure 8 As shown, the top end of the first support rod 11 is provided with a first support seat 13 for increasing the contact area between the first support rod 11 and the external support, and the top end of the second support rod 12 is provided with a second support seat 14 for increasing the contact area between the second support rod 12 and the external support.
[0083] The first support base 13 and the second support base 14 mentioned above can increase the contact area between the first support rod 11 and the second support rod 12 and external supports such as the ceiling 5, thereby increasing the friction at the contact point and ensuring the stability of the support rod assembly 1.
[0084] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
