Description

Technical Field

[0001] This invention relates to the field of shelving technology, and in particular to a shelving connection device and a shelving device. Background Technology

[0002] In related technologies, storage devices composed of various frames, hangers, and supports are widely used. However, among the numerous types and specifications of storage racks, there are common drawbacks such as inconvenient connection and complex overall assembly. To address the above-mentioned problems, Chinese Patent CN1921785A discloses a connector for a storage rack, including a sliding sleeve and a retaining sleeve. The sliding sleeve has a fastener body with an opening groove along the axial direction of the sliding sleeve, and fastening parts located on both sides of the opening groove. The retaining sleeve has a retaining groove. When the fastening part is inserted into the retaining groove, the width of the opening groove is reduced, thereby fixing the sliding sleeve to the support rod. This storage rack connector can adapt to the connection of racks of various specifications and uses, and is convenient to assemble and disassemble with reliable connection. It also allows for the addition of layers or other accessories without disassembling the entire unit, thereby expanding its applications. However, after long-term use by users, the following problems were found with the above-mentioned shelf connector: when the shelf is loaded with heavy items or when the shelf is subjected to a large pulling force, the force on the shelf will be transmitted to the buckle of the sliding sleeve through the clamp. The buckle is only connected to the sliding sleeve body through its lower fastening part, which makes the upper end of the buckle easy to break, causing the shelf connector to fail and greatly shortening the service life of the shelf device.

[0018] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0019] In the description of this invention, it should be understood that the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0020] In the description of this invention, "several" means one or more, "more than" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0021] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0022] In related technologies, storage devices composed of various frames, hangers, and supports are widely used. However, among the numerous types and specifications of storage racks, there are common drawbacks such as inconvenient connection and complex overall assembly. To address the above-mentioned problems, Chinese Patent CN1921785A discloses a connector for a storage rack, including a sliding sleeve and a retaining sleeve. The sliding sleeve has a fastener body with an opening groove along the axial direction of the sliding sleeve, and fastening parts located on both sides of the opening groove. The retaining sleeve has a retaining groove. When the fastening part is inserted into the retaining groove, the width of the opening groove is reduced, thereby fixing the sliding sleeve to the support rod. This storage rack connector can adapt to the connection of racks of various specifications and uses, and is convenient to assemble and disassemble with reliable connection. It also allows for the addition of layers or other accessories without disassembling the entire unit, thereby expanding its applications. However, after long-term use by users, the following problems were found with the above-mentioned shelf connector: when the shelf is loaded with heavy items or when the shelf is subjected to a large pulling force, the force on the shelf will be transmitted to the buckle of the sliding sleeve through the clamp. The buckle is only connected to the sliding sleeve body through its lower fastening part, which makes the upper end of the buckle easy to break, causing the shelf connector to fail and greatly shortening the service life of the shelf device.

[0023] Therefore, referring to Figures 1 to 14 , Figure 18 A first aspect of the present invention provides a shelf connecting device for connecting and installing a shelf 500 onto a support rod 400. (See also...) Figure 1 The shelf connecting device includes a positioning sleeve 100, a retaining sleeve 200, and a reinforcing sleeve 300. The positioning sleeve 100 can be positioned at any position on the support rod 400. Specifically, the positioning sleeve 100 is provided with an openable sleeve 110, which can be closed and fitted onto the outer wall of the support rod 400, and can also be opened and detached from the support rod 400. Specifically, there are two sleeves 110, one end of which can be hinged together by a structure such as a hinge, and the other end of which forms an opening 111. (Refer to...) Figure 4 When the two sleeves 110 open relative to each other, the opening 111 widens, allowing the sleeves 110 to release their positioning relationship with the support rod 400; see reference. Figure 3 When the two sleeves 110 surround each other, the opening 111 narrows, thereby tightening the sleeves 110 against the outer wall of the support rod 400 to achieve positioning. The positioning sleeve 100 is also provided with a snap-fit ​​block 120 located outside the opening 111 of the sleeve 110, and a snap-fit ​​part 121 is provided between the snap-fit ​​block 120 and the sleeve 110.

[0024] Reference Figure 2 and Figure 7 The sleeve 200 is used to connect the shelf 500. For example, the outer wall of the sleeve 200 may be provided with a connecting rod 220 that connects to the shelf 500, or the sleeve 200 itself may be part of the shelf 500. The sleeve 200 is provided with a slot 210, through which the sleeve 200 can be engaged with the buckle part 121, thereby reducing the width of the opening 111 of the sleeve 110 and thus allowing the sleeve 110 to be fixed to the support rod 400.

[0025] Reference Figure 1 and Figure 2The reinforcing sleeve 300 is installed on the positioning sleeve 100 so that the tensile force on the snap-fit ​​block 120 can be transmitted through the reinforcing sleeve 300. For example, it can be transmitted through the reinforcing sleeve 300 to the sleeve 110, and then through the sleeve 110 to the support rod 400. This reduces the tensile force on the snap-fit ​​block 120, preventing damage due to excessive tensile force, improving the structural strength of the shelf connection device, and thus extending its service life. Specifically, the reinforcing sleeve 300 can be installed on the upper end of the positioning sleeve 100 or tightened onto the outer wall of the positioning sleeve 100. For example, the upper end faces of the sleeve 110 and the snap-fit ​​block 120 can be provided with reinforcing holes, and the lower end face of the reinforcing sleeve 300 can be provided with reinforcing posts. The reinforcing sleeve 300 is installed on the upper end of the positioning sleeve 100 by inserting the reinforcing posts into the reinforcing holes. In this case, the tensile force on the snap-fit ​​block 120 is transmitted to the sleeve 110 through the reinforcing posts of the reinforcing sleeve 300. For example, the reinforcing sleeve 300 is a long, flexible piece that can be wrapped around the outer wall of the positioning sleeve 100 and tied tightly, so that the tension on the snap-fit ​​block 120 can be transmitted to the sleeve 110 through the flexible piece.

[0026] The shelf connecting device of this invention is provided with a reinforcing sleeve 300, which is installed on the positioning sleeve 100. This allows the tensile force on the locking block 120 to be transmitted to the sleeve 110 through the reinforcing sleeve 300, thereby reducing the tensile force on the locking block 120 and preventing the locking block 120 from being damaged due to excessive tensile force. This improves the structural strength of the shelf connecting device and thus extends its service life.

[0027] Reference Figure 6 , Figure 12 and Figure 14In some embodiments of the present invention, to facilitate quick installation of the reinforcing sleeve 300, the reinforcing sleeve 300 is fitted onto the upper end of the positioning sleeve 100. The reinforcing sleeve 300 is provided with an upper edge portion 340 and a side portion 330 connected to each other. When the reinforcing sleeve 300 is fitted onto the upper end of the positioning sleeve 100, the upper edge portion 340 can abut against the upper end face of the sleeve 110 and the upper end face of the snap-fit ​​block 120, and the side portion 330 can abut against the outer side surface of the sleeve 110 and the outer side surface of the snap-fit ​​block 120. Thus, when the snap-fit ​​block 120 is subjected to the pulling force transmitted from the snap-fit ​​sleeve 200, the snap-fit ​​block 120 can transmit the pulling force to the sleeve 110 through the side portion 330 and the upper edge portion 340. Specifically, the inner wall of the side portion 330 may also be provided with protruding ribs 331. Multiple protruding ribs 331 may be provided, spaced apart on the inner wall of the side portion 330, allowing the side portion 330 to better abut against the outer surfaces of the sleeve 110 and the snap-fit ​​block 120. The bottom of the protruding rib 331 may also have an inclined guide portion, enabling the reinforcing sleeve 300 to be pre-positioned and quickly secured when fitted onto the positioning sleeve 100 from top to bottom, making installation faster and more convenient.

[0028] Reference Figure 2 , Figure 5 and Figure 6 It is understood that, to further facilitate the quick installation and removal of the reinforcing sleeve 300, in some embodiments of the present invention, the reinforcing sleeve 300 includes a first component 310 and a second component 320, with the first component 310 detachably connected to the second component 320. By providing the first component 310 and the second component 320, the reinforcing sleeve 300 can be quickly installed onto the positioning sleeve 100 at any position on the support rod 400, eliminating the need to slip the support rod 400 onto one end before installing it onto the positioning sleeve 100. This greatly improves the ease of installation and removal. For example, the first component 310 and the second component 320 can be connected by a hinge at one end and a snap-fit ​​connection at the other end. In use, the first component 310 and the second component 320 can be opened and then fitted around the upper end of the positioning sleeve 100.

[0029] Reference Figure 18 and Figure 19In some other embodiments of the present invention, the structure of the reinforcing sleeve 300 can be simpler. In this case, the reinforcing sleeve 300 can only be provided with a side portion 330. When the reinforcing sleeve 300 is sleeved on the upper end of the positioning sleeve 100, the inner side of the side portion 330 can abut against the outer side of the sleeve 110 and the snap-fit ​​block 120, so that the tension received by the snap-fit ​​block 120 can be transmitted to the sleeve 110 through the reinforcing sleeve 300, and then to the support column 400. Alternatively, the first kit 310 may have a connected upper edge 340 and a side part 330, while the second kit 320 may only have a side part 330. The first kit 310 may be fitted onto the upper end of the snap-fit ​​block 120, and the second kit 320 may be fitted onto the upper end of the sleeve 110. This allows the snap-fit ​​block 120 to transmit tension through the upper edge 340 and the side part 330, enabling the tension on the snap-fit ​​block 120 to be better transmitted through the first kit 310, reducing the tension on the snap-fit ​​block 120 and preventing the snap-fit ​​block 120 from being easily damaged.

[0030] Reference Figure 5 and Figure 6 Of course, the connection method of the first kit 310 and the second kit 320 can also be in other forms. For example, in some embodiments of the present invention, both the first kit 310 and the second kit 320 are semi-annular. One of the first kit 310 and the second kit 320 is provided with a positioning post 312, and the other is provided with a matching positioning hole 322. The first kit 310 and the second kit 320 are detachably connected by inserting the positioning post 312 into the positioning hole 322. In use, one of the first kit 310 and the second kit 320 can be first sleeved on one side of the upper end of the positioning sleeve 100, and then the other can be sleeved on the other side of the upper end of the positioning sleeve 100. At the same time, the positioning post 312 is inserted into the positioning hole 322 to realize the connection of the first kit 310 and the second kit 320. The installation operation is very convenient.

[0031] Reference Figure 6 In some embodiments of the present invention, two positioning posts 312 are provided, and the two positioning posts 312 are respectively located at both ends of the first kit 310. Two positioning holes 322 are also provided, and the two positioning holes 322 are respectively located at both ends of the second kit 320. Therefore, during installation, the second kit 320 is first fitted onto one side of the upper end of the positioning sleeve 100, and then the first kit 310 is fitted onto the other side of the upper end of the positioning sleeve 100. At this time, the two ends of the first kit 310 can be engaged in the positioning holes 322 at both ends of the second kit 320 through the positioning posts 312, which can improve the connection strength between the first kit 310 and the second kit 320 and facilitate the better transmission of the tension received by the engaging block 120 to the sleeve 110.

[0032] In some embodiments of the present invention, the upper portions of both ends of the first kit 310 extend circumferentially to form first extension portions 311, and positioning posts 312 are formed at the lower ends of the first extension portions 311; the lower portions of both ends of the second kit 320 extend circumferentially to form second extension portions 321 that match the first extension portions 311, and positioning holes 322 are formed in the second extension portions 321. Therefore, when the first kit 310 and the second kit 320 are connected by inserting the positioning posts 312 into the positioning holes 322, the first extension portion 311 overlaps the upper end of the second extension portion 321, so that the upper end surface of the first extension portion 311 is substantially flush with the upper end surface of the second kit 320, and the lower end surface of the second extension portion 321 is substantially flush with the lower end surface of the first kit 310, making the overall structure of the reinforcing sleeve 300 simpler. Of course, the first assembly 310 can also be configured with a positioning post 312 at one end and a positioning hole 322 at the other end; while the second assembly 320 can be configured with a positioning hole 322 at one end and a positioning post 312 at the other end, so that the positioning post 312 and positioning hole 322 of the first assembly 310 can correspond to the positioning hole 322 and positioning post 312 of the second assembly 320, realizing a detachable connection between the two ends of the first assembly 310 and the second assembly 320. (Refer to...) Figure 6 Of course, the second extension 321 can also be formed by extending circumferentially from the middle of both ends of the second kit 320. When the first kit 310 and the second kit 320 are connected by inserting the positioning pin 312 into the positioning hole 322, the first extension 311 overlaps the upper end of the second extension 321, so that the upper end face of the first extension 311 can be basically flush with the upper end face of the second kit 320, and the lower end face of the second extension 321 can form a notch with the lower end face of the first kit 310. The notch can avoid the connecting rod 220 of the sleeve 200.

[0033] Reference Figure 1 , Figure 8 and Figure 13 It is understandable that, in order to further reduce the tensile force on the locking block 120 and prevent it from being easily damaged, in some embodiments of the present invention, the reinforcing sleeve 300 is simultaneously fitted onto the upper end of the positioning sleeve 100 and the upper end of the locking sleeve 200, so that the tensile force on the locking sleeve 200 can also be transmitted to the sleeve 110 and then to the outside through the reinforcing sleeve 300. When the shelf is under force, the tensile force is transmitted to the locking block 120 through the locking sleeve 200. When the reinforcing sleeve 300 is fitted onto the upper end of the locking sleeve 200, part of the tensile force on the locking sleeve 200 will be transmitted to the sleeve 110 through the reinforcing sleeve 300, and then from the sleeve 110 to the support rod 400. Therefore, the tensile force on the locking block 120 can be further reduced, which is beneficial to improving the service life of the shelf connecting device.

[0034] Reference Figures 8 to 14In some embodiments of the present invention, the sleeve 200 is provided with a hook 230, and the reinforcing sleeve 300 is provided with a locking hole 350. When the reinforcing sleeve 300 is sleeved on the upper end of the positioning sleeve 100, the sleeve 200 can be connected to the reinforcing sleeve 300 by locking the hook 230 into the locking hole 350. This can improve the stability of the reinforcing sleeve 300 installed on the sleeve 200, and at the same time increase the connection force points between the reinforcing sleeve 300 and the sleeve 200, so that more of the tensile force on the sleeve 200 can be transmitted to the sleeve 110 through the reinforcing sleeve 300.

[0035] Reference Figure 9 , Figure 13 and Figure 14 It is understood that in some embodiments of the present invention, the first kit 310 is sleeved on the upper end of the snap-fit ​​block 120, the second kit 320 is sleeved on the upper end of the sleeve 110, the connection between the first kit 310 and the second kit 320 is sleeved on the upper end of the ferrule 200, and the snap-fit ​​hole 350 is provided at the end of the second kit 320 near the first kit 310, so that part of the tension on the ferrule 200 can be directly transmitted to the sleeve 110 through the second kit 320, reducing the force between the first kit 310 and the second kit 320, which is beneficial to improving the connection stability of the first kit 310 and the second kit 320. The inner wall of the card hole 350 may also be provided with a protruding snap-fit ​​part 351. The snap-fit ​​part 351 is roughly semi-cylindrical. During installation, the hook 230 can be quickly snapped into the card hole 350 under the guidance of the semi-cylindrical snap-fit ​​part 351. Then the hook 230 can be limited by the snap-fit ​​part 351 to connect the sleeve 200 to the second kit 320.

[0036] Reference Figure 15 and Figure 16 According to a second aspect of the present invention, a shelf connecting device includes a positioning sleeve 100, a retaining sleeve 200, and a reinforcing sleeve 300. The positioning sleeve 100 is provided with an openable sleeve 110, which can be sleeved around the outer wall of the support rod 400. The positioning sleeve 100 is also provided with a retaining block 120 located outside the opening of the sleeve 110, and a snap-fit ​​portion 121 is provided between the retaining block 120 and the sleeve 110. The sleeve 200 is connected to the shelf 500. The sleeve 200 is provided with a slot 210, through which the sleeve 200 can be engaged with the buckle part 121, thereby reducing the width of the opening 111 of the sleeve 110 and allowing the sleeve 110 to be fixed to the support rod 400. The reinforcing sleeve 300 is provided with a locking hole 350, and the sleeve 200 is provided with a locking hook 230. The sleeve 200 can be engaged with the locking hole 350 through the locking hook 230 and connected to the reinforcing sleeve 300, so that the tensile force on the sleeve 200 can be transmitted to the reinforcing sleeve 300, and then transmitted to the outside through the reinforcing sleeve, thereby reducing the tensile force transmitted from the sleeve 200 to the locking block 120 and preventing the locking block 120 from being easily damaged. This embodiment and Figure 8 The main difference between the two embodiments of the shelf connection device is that the reinforcing sleeve 300 in this embodiment only needs to be provided with the second component 320, and does not need to be provided with the first component 310. Therefore, the structure of this embodiment is simpler. It should be noted that this embodiment is more suitable for a fan-shaped shelf 500. In this case, the force-bearing points of both ends of the shelf 500 and the card sleeve 200 are located just below the connection points of the two ends of the second component 320 and the two hooks 230 of the card sleeve 200. Therefore, the force on the card sleeve 200 can be better transmitted to the second component 320 and transmitted to the outside through the second component 320.

[0037] Reference Figure 7 and Figure 17 A storage device according to a third aspect embodiment of the present invention includes a support rod 400, a shelf 500, and a shelf connecting device according to a first or second aspect embodiment of the present invention. The shelf 500 is mounted to the shelf connecting device via a clip 200, and the shelf connecting device is mounted to the support rod 400 via a positioning sleeve 100. Of course, multiple shelves 500 can be provided, and multiple shelf connecting devices can be provided accordingly. Each shelf 500 can be quickly mounted to the support rod 400 via a corresponding shelf connecting device, making installation quick and convenient.

[0038] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
