Description

Technical Field

[0001] This application relates to the technical field of shelving, and in particular to a rail and shelving. Background Technology

[0002] Shelves are commonly used in daily life. Their main structure includes a frame and shelves or cabinets connected to the frame. Rails are supporting components connected to the frame, serving to support the shelves or cabinets and also providing sliding guidance.

[0003] Existing installation methods for rails and shelves typically use fasteners, which makes rail assembly and disassembly relatively cumbersome. To achieve quick assembly and disassembly, a utility model patent with authorization announcement number CN221931596U discloses a "rail and shelf". The rail has spaced-apart locking parts, each with a first locking member and a second locking member distributed vertically. When connecting to the shelf, the first or second locking member first enters a locking hole on the shelf, and then the other locking member engages to complete the installation of the rail. The installation method is essentially a snap-fit ​​structure, making assembly and disassembly more convenient compared to fastener connections.

[0004] However, when connecting the above structure to the frame, it is necessary to pass one end of each of the two spaced-apart locking parts through the locking holes simultaneously before the other end can be engaged. In actual operation, because the rail has a certain length, in order to ensure that the two locking parts with a certain distance between them are simultaneously inserted into the locking holes, it is necessary to operate with both hands. That is, both hands must hold the connection points where the two locking parts are located to facilitate the connection operation. When the rail is too long, two people are required to operate the installation at the same time, which still presents an inconvenience in installation. Utility Model Content

[0005] To facilitate installation and operation, the primary objective of this application is to provide a support rail.

[0006] The rail provided in this application adopts the following technical solution: A type of rail, comprising: Supporting part; A first connector connects to the support portion. The first connector includes an inlet section extending along the length direction of the support portion and a lower edge section connecting to the inlet section and forming a certain angle with the inlet section. A first hook portion is formed between the lower edge section and the inlet section. The second connector connects to the support portion and is spaced apart from the first connector. The second connector has a second hook portion.

[0007] Preferably, the first connector further includes: A limiting part is connected to a supporting part, and the guide section is connected to one side of the limiting part; The third hook portion is formed by a gap between the inlet section and the support portion, and the limiting portion has a limiting surface at the third hook portion.

[0008] Preferably, the end face of the limiting part away from the limiting surface is a first wedge-shaped surface, and the first wedge-shaped surface is inclined from one end of the supporting part toward the direction of the guiding section.

[0009] Preferably, the inlet segment has a second wedge-shaped surface at its end.

[0010] Preferably, the second connector includes: Supporting part, connected to the supporting part; and The engaging portion extends outward from one end of the supporting portion, and the engaging portion and the supporting portion are spaced apart to form the second hook portion.

[0011] Preferably, the opening of the second hook faces downward.

[0012] Preferably, the top of the engaging portion has a third wedge-shaped surface, and the bottom of the engaging portion has a fourth wedge-shaped surface.

[0013] Preferably, the support portion includes: Support plate; A limiting plate is connected to one side of the supporting plate, and both the first connecting member and the second connecting member are connected to one end face of the limiting plate; and A baffle plate is connected to one end of the support plate and the limiting plate. The support plate, the limiting plate, and the baffle together form a support groove with an opening on one side.

[0014] Preferably, the supporting portion further includes an extension plate extending outward from the supporting plate and / or the limiting plate, wherein one end face of the extension plate is on the same plane as one end face of the limiting plate.

[0015] To facilitate installation and operation, the second objective of this application is to provide a storage rack.

[0016] The storage rack provided in this application adopts the following technical solution: A storage rack, comprising: At least one first pipe fitting, wherein the first pipe fitting has a first locking hole on a first side; At least one second pipe fitting is arranged at intervals on one side of the first pipe fitting, and the second pipe fitting has a second locking hole on its second side; and The aforementioned support rail is connected to the first pipe fitting and the second pipe fitting; The guide section extends into the first card hole, and the first hook engages with the first card hole; the second hook engages with the second card hole. In summary, this application includes the following beneficial technical effects: The initial connection and positioning of the entire rail is achieved by pre-inserting the guide section of the first connector into the corresponding slot of the frame. Then, the second connector is connected to another slot to complete the overall installation of the rail without having to connect the first connector and the second connector simultaneously. This method can achieve the installation of the rail more quickly, especially in environments where rails of a certain length are installed. Attached Figure Description

The terminology used herein in the specification of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items. Example 1

[0022] Figure 1 A rail structure is shown, including a support portion 11 and a first connector 12 and a second connector 13 connected to the same side of the support portion 11. The support portion 11 includes a support plate 111, a limiting plate 112, and a baffle 113. The limiting plate 112 is connected to one side of the support plate 111, and the baffle 113 is connected to the ends of the limiting plate 112 and the support plate 111. The support plate 111, the limiting plate 112, and the baffle 113 together form a support groove 114 with an opening on one side. In this embodiment, the support plate 111 and the limiting plate 112 are arranged at a 90° angle. The support groove 114 is used to support the partition or cabinet 3 while providing guidance for the sliding of the partition or cabinet 3. The baffle 113 is used to limit the displacement of the partition or cabinet 3 on one side.

[0023] Combination Figure 2 and Figure 3 In this embodiment, the first connector 12, the second connector 13, and the support part 11 are an integral structure. The entire rail 1 can be made of metal or non-metal, and the specific material is selected according to the load.

[0024] Both the first connector 12 and the second connector 13 are connected to the end face of the limiting plate 112 away from the support groove 114. The first connector 12 includes a limiting part 123, an inlet section 121 extending outward from one side of the limiting part 123, and a lower edge section 122 connecting the inlet section 121. The extension direction of the inlet section 121 is parallel to the length direction of the support part 11 or within a 45° angle. In this embodiment, the extension direction of the inlet section 121 is parallel to the length direction of the support part 11.

[0025] The lower edge segment 122 extends downward from the lower edge of the guide segment 121, and the lower edge segment 122 and the guide segment 121 form an angle to form a first hook portion 124. The guide segment 121 and the limiting plate 112 have a gap to form a third hook portion 125. The end face of the limiting portion 123 away from the limiting surface 1232 is a first wedge-shaped surface 1231, and the wedge-shaped surface is inclined from one end of the supporting portion 11 toward the guide segment 121. The guide segment 121 has a second wedge-shaped surface 1211 at its end.

[0026] The second connector 13 includes a support portion 131 and an engaging portion 132. The support portion 131 is connected to a limiting plate 112. The engaging portion 132 extends outward from one end of the support portion 131. Similarly, a second hook portion 133 is formed between the engaging portion 132 and the limiting plate 112. In this embodiment, the engaging portion 132 extends downward from one end of the support portion 131, so that the opening of the second hook portion 133 faces downward. Of course, the engaging portion 132 can also extend downward from one end of the support portion 131 and between 0-180°.

[0027] The top of the engaging portion 132 has a third wedge-shaped surface 1321, and the bottom of the engaging portion 132 has a fourth wedge-shaped surface 1322. The third wedge-shaped surface 1321 and the fourth wedge-shaped surface 1322 have the same inclination direction and are both inclined from the upper edge of the limiting plate 112 toward the lower edge.

[0028] The support portion 11 also includes an extension plate 115, which extends outward from one end of the support plate 111 and / or the limiting plate 112. In this embodiment, the extension plate 115 extends outward from one end of the support plate 111 and the limiting plate 112, thereby increasing the area at the connection between the extension plate 115 and the support plate 111 and the limiting plate 112. Simultaneously, one end face of the extension plate 115 and one end face of the limiting plate 112 are on the same plane, further increasing the area of ​​contact with the frame 2. Example 2

[0029] Figure 4 and Figure 5 The structure of a storage rack is shown, including a frame 2 and several cabinets 3 slidably connected to the frame 2. The frame 2 includes multiple first pipes 21 arranged in the same row and spaced apart, and adjacent second pipes 22. The two first pipes 21 and the two second pipes 22 enclose a pull-out area 23 for the cabinets 3 to be received. The first pipes 21 and the second pipes 22 on the same side are connected to the rails 1 in Embodiment 1. Each pull-out area 23 is provided with two rails 1 arranged symmetrically. The lower end face of the cabinets 3 is supported by the support grooves 114 of the two rails 1.

[0030] See also Figures 6 to 8Both the first pipe fitting 21 and the second pipe fitting 22 are hollow pipe fittings. The first pipe fitting 21 has a first locking hole 212 on the first side 211, and the second pipe fitting 22 has a second locking hole 222 on the second side 221. The first side 211 and the second side 221 are on different planes.

[0031] During installation, the first connector 12 is first connected to the first pipe 21, and then the second connector 13 is connected to the second pipe 22 to complete the installation. Specifically, the guide section 121 first extends into the first locking hole 212, so that the limiting surface 1232 of the limiting part 123 in the third hook part 125 abuts against the first side 211. The first connector 12 of the rail 1 is moved down so that the first hook part 124 engages with the first locking hole 212.

[0032] When the second connector 13 is connected to the second pipe 22, the engaging part 132 is inserted into the second locking hole 222. The second connector 13 of the lower support rail 1 causes the second hook part 133 to engage with the second locking hole 222. The sides of the limiting plate 112 and the extension plate 115 abut against the first pipe 21 and the second pipe 22.

[0033] During installation of this rail 1, the first connector 12 serves as a positioning and initial connection, replacing the existing connection method that requires simultaneous installation of the snap-fit ​​part, thus improving the overall installation efficiency of the rail 1.

[0034] 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.
