Description

Technical Field

[0001] This utility model relates to a fixing device, and more particularly to a cord buckle for fixing the edge of a flexible curtain.

[0002] This utility model also relates to a linen cart that uses the aforementioned rope buckle. Background Technology

[0003] A linen cart, usually called a housekeeping cart, is a specialized transport vehicle used in logistics services to efficiently and hygienically handle large quantities of linens (such as sheets, duvet covers, towels, bathrobes, tablecloths, etc.).

[0004] In existing linen carts, to facilitate access to the contents, the enclosure structure often takes two forms: a rigid hinged door and a soft fabric cover. While rigid doors offer better sealing and structural stability, they require a certain amount of operating space to open and increase the overall weight and structural complexity.

[0005] In contrast, fabric covers are widely used due to their lightweight, flexibility, and ease of installation and removal. These fabric covers typically only have their top edge fixed to the vehicle body, while the left, right, and bottom edges are left free without any reliable fixing structure.

[0006] This completely open fabric cover design has significant drawbacks in practical use, especially in mobile equipment or outdoor environments: the cover is prone to significant swaying and rolling due to wind or inertia, not only exposing items inside the vehicle and posing a risk of items falling or becoming contaminated, but also weakening its basic dustproof, protective, and privacy functions. Currently, users may temporarily bind the cover with ropes, rubber bands, etc., but these methods lack dedicated design, the fixing effect is unstable, and temporary binding materials are easily lost or damaged. More importantly, existing fabric cover and its carrier design do not provide a structural, repeatable, and robust solution to constrain the free edges of the cover, resulting in an inability to effectively guarantee the cover's sealing function, affecting the practicality and applicable scenarios of the equipment. Therefore, there is an urgent need for a dedicated fixing design for fabric covers that can provide reliable constraint to fill this gap in existing technology. Summary of the Invention

[0007] The main purpose of this utility model is to propose a rope buckle for a cloth cover and a linen cart with it, aiming to solve the problems of the free edge of the cloth cover of the existing linen cart being easy to flutter and not sealing properly.

[0008] To achieve the above objectives, this utility model proposes a cord buckle for a cloth cover, comprising a main body and a cord. The main body is used to detachably fix it to the edge of the cloth cover; The rope is connected to the main body and forms a loop, which is used to cooperate with the corresponding part of the linen cart to restrain the movement of the corresponding position of the edge of the cloth cover.

[0009] Preferably, the rope is long and narrow, and both ends of the rope are connected to the main body to form the loop portion; Alternatively, the rope itself may be a closed loop structure, with local sections of the rope connected to the main body.

[0010] Preferably, the main body includes a first clamping member and a second clamping member, the first clamping member and the second clamping member being detachably connected, for clamping the edge of the cloth cover between the first clamping member and the second clamping member; The first clamping member and the second clamping member are connected by bolts or snap-fit ​​structure.

[0011] Preferably, the first clamping member has a receiving groove on the side facing the second clamping member; When the rope is long and narrow, its two ends are fixed in the receiving groove as connecting parts. When the rope is a closed loop structure, a local section of it is fixed in the receiving groove as a connecting part. The portion of the rope outside the receiving groove forms the loop; When the second clamping member is connected to the first clamping member, at least a portion of the opening of the receiving groove is blocked by the second clamping member to prevent the connecting part from coming out of the receiving groove.

[0012] Preferably, the receiving groove is U-shaped, including one groove opening and two clearance openings, wherein the planes where the two clearance openings are located are perpendicular to the plane where the groove opening is located; When the rope is long and narrow: The two ends of the rope are directly clamped and fixed between the first clamping member and the second clamping member; Alternatively, the rope has enlarged portions at both ends that are larger than the main body of the rope, and a pair of limiting flanges are provided in the receiving groove for each end of the rope. The gap between each pair of limiting flanges allows the main body of the rope to pass through but blocks the enlarged portions from passing through. When the second clamping member is connected to the first clamping member, it covers the bulging part to prevent the bulging part at the end of the rope from coming out of the slot; When the rope is a closed loop structure: A portion of the rope is embedded in the receiving groove, and the sidewall of the receiving groove prevents the portion from detaching from the clearance opening. When the second clamping member is connected to the first clamping member, it covers the portion to confine the portion within the receiving groove.

[0013] Preferably, the first clamping member and the second clamping member are connected by bolts; The second clamping element is a pad with a central hole; The first clamping member has a positioning step on the side facing the second clamping member, next to the opening of the receiving groove, for supporting and positioning the pad; The positioning step is provided with a corresponding screw hole. The shank of the bolt passes through the central hole and is screwed into the screw hole to press the gasket into the positioning step.

[0014] Preferably, the rope is an elastic rope; Alternatively, the rope may be a non-elastic rope.

[0015] Preferably, the body is made of plastic or metal.

[0016] This utility model also proposes a linen cart, including a cart body and a cloth cover, wherein the top edge of the cloth cover is connected to the cart body, and at least one of the above-mentioned rope buckles is provided on at least one free edge of the cloth cover. The vehicle body is provided with a corresponding part that mates with the annular part.

[0017] Preferably, the left edge, right edge and bottom edge of the cloth cover are each provided with a plurality of the cord buckles.

[0018] This utility model's technical solution utilizes a detachable rope buckle and its resulting loop on the free edge of the linen cover. This allows for reliable hooking with corresponding parts on the linen cart body, such as crossbars and protrusions, effectively restraining the cover's edges and preventing it from fluttering or rolling during movement or in windy conditions. This significantly improves the cover's sealing stability and protective effect. The structure is simple and practical; the main body is detachable for easy cleaning or replacement of the cover, and the loop design makes hooking intuitive and secure. Furthermore, the rope buckle's structural design, especially the limiting and clamping method at the rope connection, ensures reliable connection over long-term use and prevents loosening. The overall solution effectively overcomes the lack of fixing function in traditional linen covers, enhancing the practicality and environmental adaptability of the linen cart.

[0020] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0021] It should be noted that if any directional indication (such as up, down, left, right, front, back, top, bottom, inside, outside, vertical, horizontal, longitudinal, counterclockwise, clockwise, circumferential, radial, axial, etc.) is involved in the embodiments of this utility model, the directional indication is only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0022] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0023] This utility model proposes a rope buckle for a cloth cover and a linen cart having the same, the main purpose of which is to solve the problems of the free edge of the cloth cover of existing linen carts being prone to floating and not sealing properly. The rope buckle has a main body that is detachably installed on the edge of the cloth cover and a ring-shaped part 11 extending from the main body, which hooks and engages with a corresponding structure on the body 4 of the linen cart, thereby constraining the position of the edge of the cloth cover.

[0024] In this embodiment of the utility model, such as Figures 1 to 3As shown, the cord fastener for the fabric cover includes a main body and a cord 1. The main body is designed to detachably clamp or fix to the free edge of the fabric cover, such as the left edge, right edge, or bottom edge. The cord 1 is connected to the main body. Specifically, the cord 1 can be a long strip of tape or rope, with both ends fixedly connected to the main body, so that the middle part of the cord 1 naturally forms a loop 11. As an equivalent alternative, the cord 1 itself can also be a pre-made closed loop structure, such as a rubber ring or rope loop. In this case, a section of the loop cord 1 is fixedly connected to the main body, and the unfixed part of the loop cord 1 constitutes the loop 11 that can be used for hooking.

[0025] The annular portion 11 is used to hook or fit onto the corresponding part 100 of the linen cart. This corresponding part 100 can be any protruding structure inherent on the linen cart body 4 suitable for hooking, such as the crossbars or vertical bars of the frame, a special hook, the head of the protruding bolt 3, etc., or it can be a special hook or pull ring additionally installed on the cart body 4. By engaging the annular portion 11 with these corresponding parts 100, the position on the cloth cover where the rope buckle is installed is restrained, preventing it from floating freely, thereby improving the sealing effect of the cloth cover.

[0026] Specifically, this embodiment details the specific structure of the main body: the main body includes a first clamping member 21 and a second clamping member 22. The first clamping member 21 and the second clamping member 22 are detachably connected and work together to clamp the edge of the fabric cover between them. A common connection method is to use bolts and nuts for fastening; another convenient method is to use a snap-fit ​​structure, which allows the first clamping member 21 and the second clamping member 22 to be quickly engaged and disengaged.

[0027] Specifically, this embodiment further discloses a specific connection structure between the rope 1 and the main body: a receiving groove 23 is provided on the side of the first clamping member 21 facing the second clamping member 22. When the rope 1 is elongated, its two ends are placed and fixed in the receiving groove 23 as connecting parts; when the rope 1 is a closed loop, a partial section of it is accommodated in the receiving groove 23 as a connecting part. The portion of the rope 1 outside the receiving groove 23 naturally forms the loop portion 11.

[0028] When the second clamping member 22 is connected to the first clamping member 21, its structure at least partially blocks the opening 25 of the receiving groove 23. This design serves as a limit, preventing the connecting part of the rope 1 from accidentally coming out of the opening 25, thereby ensuring the reliability of the connection.

[0029] Specifically, this embodiment provides a preferred solution for fixing the receiving groove 23 and the rope 1: the receiving groove 23 can be designed as a U-shape, which has a main groove 25 and two side clearance openings 26, the plane of which the two clearance openings 26 are located is approximately perpendicular to the plane of which the groove 25 is located.

[0030] Specifically, for the long, narrow rope 1, there are two ways to fix it: Firstly, both ends of the rope 1 can be directly clamped between the first clamping member 21 and the second clamping member 22, and fixed by clamping force.

[0031] Secondly, as a more robust solution, an enlarged portion larger than the diameter or width of the rope 1 can be provided at each end of the rope 1, such as a knotted lump, a thermoformed sphere, or a fitted metal piece. Correspondingly, a pair of limiting flanges 24 are provided within the receiving groove 23 at the position corresponding to each end of the rope 1. The gap between each pair of limiting flanges 24 allows the main body of the rope 1 to pass through, but blocks the passage of the enlarged portion at the end. When the second clamping member 22 is installed on the first clamping member 21 and covers the slot 25, it presses the enlarged portion into the receiving groove 23, thereby effectively locking the rope 1 and preventing it from being pulled out.

[0032] Specifically, for the closed loop rope 1, a section of it is embedded into the U-shaped receiving groove 23 during fixing. The sidewalls of the receiving groove 23 prevent the section from sliding laterally out of the two clearance openings 26. Similarly, after the second clamp 22 is installed, it covers the section and confines it within the groove, thereby completing the fixing.

[0033] Specifically, this embodiment describes a specific structure for the bolt 3 connection: On the side of the first clamping member 21 facing the second clamping member 22, a positioning step 27 is provided next to the slot 25 of the U-shaped receiving groove 23. The second clamping member 22 can be a washer with a central hole. During installation, the washer is placed on the positioning step 27, where it is supported and radially positioned. A screw hole 28 is provided on the positioning step 27. During assembly, the shank of the bolt 3 passes through the central hole of the washer and is screwed into the screw hole 28 of the first clamping member 21. As the bolt 3 is tightened, the washer is pressed into the positioning step 27, thereby firmly clamping the edge of the fabric cover placed in the receiving groove 23 and the connecting part of the rope 1 together.

[0034] Specifically, the rope 1 can be selected with different characteristics as needed: for example, an elastic rope 1, such as a rubber band or elastic rope, can be selected, which provides a certain amount of flexibility when hooking, making it easy to install and adapt to corresponding parts 100 at different distances. Alternatively, a non-elastic rope 1, such as a nylon rope or polyester tape, can be selected to provide a more stable restraint force.

[0035] Specifically, the main body can be made of engineering plastics, which have the advantages of being lightweight, low-cost, and corrosion-resistant; or metals, such as aluminum alloys and stainless steel, can be selected to provide higher strength and durability.

[0036] Based on any of the aforementioned rope buckles, this utility model also provides an embodiment of a linen cart. The linen cart includes a cart body 4 and a cloth cover 5, with the top edge of the cloth cover 5 connected to the top of the cart body 4 in a conventional manner. The improvement lies in that at least one rope buckle as described above is provided on at least one non-fixed free edge of the cloth cover 5. Specifically, to obtain the best restraint effect, multiple rope buckles can be provided on the left edge, right edge, and bottom edge of the cloth cover 5.

[0037] Accordingly, the body 4 of the linen cart is provided with corresponding parts 100 that mate with the loops 11 of these rope buckles. For example, a tubular rod is provided at a suitable height on the side frame of the body 4, or a protrusion is provided on the bottom edge of the body 4. In use, simply lift the loops 11 of each rope buckle on the cover 5 and hook or attach them to the corresponding parts 100 on the body 4 to ensure that the edges of the cover fit snugly against the body 4, effectively preventing it from fluttering. When it is necessary to open the cover, simply remove the loops 11 from the corresponding parts 100; the operation is simple and intuitive.

[0038] This invention utilizes a detachable rope buckle and its resulting loop on the free edge of the linen cover. This allows for reliable hooking with corresponding parts on the linen cart body, such as crossbars and protrusions, effectively restraining the edge of the cover and preventing it from fluttering or rolling during movement or in windy conditions. This significantly improves the cover's sealing stability and protective effect. The structure is simple and practical; the main body is detachable for easy cleaning or replacement of the cover, and the loop design makes hooking intuitive and secure. Furthermore, the rope buckle's structural design, especially the limiting and clamping method at the rope connection, ensures reliable connection over long-term use and prevents loosening. The overall solution effectively overcomes the lack of fixing function in traditional linen covers, enhancing the practicality and environmental adaptability of the linen cart.

[0039] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
