These are merely examples and are not intended to limit the scope of protection of this application. For example, a first feature subsequently described in the specification being formed above or on a second feature can include implementations where the first and second features are formed in a direct connection, or implementations where an additional feature is formed between the first and second features, thus the first and second features may not be directly connected. Furthermore, reference numerals and / or letters may be repeated in different examples in these disclosures. This repetition is for brevity and clarity and does not in itself indicate a relationship between the various implementations and / or structures to be discussed. Further, when a first element is described in connection with or combined with a second element, the description includes implementations where the first and second elements are directly connected or combined with each other, as well as implementations where one or more other intervening elements are added to indirectly connect or combine the first and second elements with each other.
[0035] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.
[0036] Please see Figures 1 to 9 This application provides a connector 1 for connecting a first rod 21 and a second rod 22. The first rod 21 has a receiving groove 213 for accommodating the connector 1. The connector 1 includes a plug-in body 11 and a buffer body 12. The plug-in body 11 has a plug-in groove 111, which matches the end of the second rod 22 for insertion. The buffer body 12 is located at the lower end of the plug-in body 11 to buffer the pressure exerted by the second rod 22 on the plug-in body 11. In the connector 1 provided by this application, the plug-in groove 111 matches the end of the second rod 22 for insertion, thereby achieving the connection between the second rod 22 and the first rod 21. This connection method is simple and quick, and helps to improve installation efficiency. The buffer body 12 is located at the lower end of the plug body 11. When the second rod 22 is subjected to external force and thus exerts force on the connector 1, the buffer body 12 will deform to buffer the pressure exerted by the second rod 22 on the plug body 11, thereby helping to extend the service life of the connector 1.
[0037] Please see Figures 1 to 4In one embodiment, the connector 11 includes a base plate 112, a left side plate 113, a right side plate 114, and a rear side plate 115. The left side plate 113, the right side plate 114, and the rear side plate 115 are disposed on the base plate 112. The left side plate 113 is connected to the right side plate 114 through the rear side plate 115, and the left side plate 113 and the right side plate 114 are arranged opposite to each other. The base plate 112, the left side plate 113, the right side plate 114, and the rear side plate 115 enclose the connector groove 111. In some embodiments, the connector 11 is a plastic part or a metal part.
[0038] Please see Figures 1 to 4 In one embodiment, the buffer body 12 is disposed at the lower end of the connector 11. The buffer body 12 includes a first buffer portion 121 and a second buffer portion 122, both of which are connected to the base plate 112. The first buffer portion 121 includes a first end 121a and a second end 121b disposed opposite to each other, and the second buffer portion 122 includes a third end 122a and a fourth end 122b disposed opposite to each other. The first end 121a and the third end 122a are both connected to the base plate 112, and the second end 121b and the fourth end 122b are free ends. The distance from the first end 121a to the third end 122a is 'a', and the distance from the second end 121b to the fourth end 122b is 'b', where 'a' < 'b'. The included angle formed by the first buffer portion 121 and the second buffer portion 122 is 'α', where 1° ≤ α ≤ 15°. α can be a value such as 1°, 5°, 10°, or 15°. The included angle formed by the first buffer portion 121 and the second buffer portion 122 provides space for deformation of the first buffer portion 121 and the second buffer portion 122, which is beneficial for buffering the pressure on the connector 1 when it is subjected to external force. Specifically, the first buffer portion 121 and the second buffer portion 122 are plastic parts, and the first buffer portion 121, the second buffer portion 122 and the plug body 11 are integrally formed structures.
[0039] Furthermore, the connector 11 and the buffer 12 are formed directly as a whole through a one-time molding process (such as casting, injection molding, 3D printing, etc.). In addition, the connector 11 and the buffer 12 can also be combined by post-processing methods such as welding and bolting. For example, in some embodiments, the buffer 12 is a compression spring, silicone elastomer, etc., which is not specifically limited here.
[0040] Please see Figures 3 to 5In one embodiment, the opening size of the receiving groove 213 is c. When the first buffer portion 121 and the second buffer portion 122 are not subjected to external force, b > c; when the first buffer portion 121 and the second buffer portion 122 are subjected to external force and are in contact, b < c. Specifically, by squeezing the first buffer portion 121 and the second buffer portion 122, the included angle α between the first buffer portion 121 and the second buffer portion 122 changes, thereby changing the distance b from the second end 121b to the fourth end 122b. For example, when squeezing the first buffer portion 121 and the second buffer portion 122 causes the second end 121b of the first buffer portion 121 and the fourth end 122b of the second buffer portion 122 to contact and adhere, the distance b from the second end 121b to the fourth end 122b is less than the opening size c of the receiving groove 213. At this time, the connector 1 can be placed into the receiving groove 213. After the connector 1 is placed into the receiving groove 213, the buffer is no longer subjected to external force, at which point b > c, thus confining the connector 1 within the receiving groove 213. Therefore, for ease of transportation and parts storage, the connector 1 can be placed in the receiving groove 213 within the first rod 21 beforehand. The connector 1 is confined within the receiving groove 213 and will not fall out, eliminating concerns about loss during transportation and saving on packaging costs. Furthermore, after the second rod 22 is installed into the receiving groove 213 of the first rod 21, the second rod 22 applies pressure to the connector 1 under external force. The included angle α between the first buffer portion 121 and the second buffer portion 122 of the buffer body 12 increases, buffering the pressure applied by the second rod 22 to the connector 11, thereby extending the service life of the connector 1.
[0041] Furthermore, the second end 121b and the fourth end 122b have inwardly inclined surfaces, which are respectively angled with the shape of the first end 121a and the third end 122a. This inwardly inclined surface design can be applied to the receiving groove 213 with a smaller size c, increasing the usability of the connector 1 and allowing the installer to insert it more quickly during operation.
[0042] Please see Figures 1 to 3 as well as Figure 5In one embodiment, the connector 1 further includes a limiting block 13, which is disposed on the outer wall of the plug-in body 11. The groove wall of the receiving groove 213 has a limiting groove 213a corresponding to the limiting block 13. The limiting block 13 and the limiting groove 213a cooperate to restrict the connector 1 within the receiving groove 213. Specifically, the limiting block 13 is a circular protrusion. When the connector 1 is placed into the receiving groove 213, the circular protrusion falls into the limiting groove 213a, and the two cooperate, preventing the connector 1 from being pulled out of the receiving groove 213. The limiting block 13 can be disposed on the left side plate 113 and the right side plate 114 respectively. In other embodiments, the limiting block 13 can also be disposed on the rear side plate 115.
[0043] Please see Figures 1 to 3 In one embodiment, the outer sidewalls of the left side plate 113 and the right side plate 114 away from the rear side plate 115 each have a first outwardly protruding baffle 14, which is parallel to the rear side plate 115; the tops of the left side plate 113, the right side plate 114, and the rear side plate 115 each have a second outwardly protruding baffle 15, which is parallel to the bottom plate 112; the sidewall of the bottom plate 112 away from the rear side plate 115 has a downwardly protruding third baffle 16, which is parallel to the rear side plate 115; the third baffle 16, the first baffle 14, and the second baffle 15 are connected end to end. The third baffle 16, the first baffle 14, and the second baffle 15 are used to adhere to the outer surface 214 of the first rod 21 to limit the insertion body 11 into the receiving groove 213.
[0044] Please see Figures 4 to 8 In one embodiment, a bed frame includes a bed board frame 2 and a connector 1. The bed board frame 2 includes a first rod 21 and a second rod 22. The side of the first rod 21 is provided with a receiving groove 213.
[0045] The connector 1 is accommodated within the receiving groove 213, and the second rod 22 is connected to the first rod 21 via the connector 1. The connector 1 includes a plug-in body 11 and a buffer body 12. The plug-in body 11 has a plug-in groove 111, which matches the end of the second rod 22 for insertion. The buffer body 12 is located at the lower end of the plug-in body 11 to buffer the pressure exerted by the second rod 22 on the plug-in body 11. In some embodiments, there are two first rods 21, which are arranged in parallel and spaced apart. There are multiple second rods 22, all of which are installed between the two first rods 21. Specifically, both ends of each second rod 22 are respectively installed onto the two first rods 21 via the connector 1, and the multiple second rods 22 are arranged in parallel and spaced apart, thus forming the bed frame 2.
[0046] Please see Figures 4 to 9 In one embodiment, the bed frame further includes support legs 23 connected to the bed frame 2 for supporting the bed frame 2. Each support leg 23 has multiple first screw holes 231 along its height direction, and the side of the bed frame 2 has second screw holes 24. The second screw holes 24 are screwed to one of the first screw holes 231 using screws 25. The user can flexibly adjust the height of the support legs 23 as needed. The user can select the appropriate height of the first screw holes 231 and the second screw holes 24 to secure them together, thereby adjusting the height of the support legs 23. In some embodiments, the support leg 23 is an L-shaped strip plate 232, and the bed frame 2 is a rectangular bed frame 2. The strip plate 232 has multiple first screw holes 231 along its length direction, and the four corners of the rectangular bed frame 2 are respectively installed using screws 25 and correspondingly on the strip plate 232.
[0047] Please see Figures 4 to 9 In one embodiment, the bed frame 2 further includes a U-shaped connecting frame 26. The first rod 21 includes a first side rod 211 and a second side rod 212. The U-shaped connecting frame 26 has two opposite ends, which are hinged to the first side rod 211 and the second side rod 212 respectively, allowing the first side rod 211 and the second side rod 212 to rotate relative to each other. Folding the first side rod 211 and the second side rod 212 in this way helps reduce the volume of the bed frame 2, facilitating packaging and transportation, and also saving space during storage. In some embodiments, to further enhance the stability and load-bearing capacity of the bed frame 2, a support leg 23 is installed below the U-shaped connecting frame 26 to provide more support for the bed frame 2.
[0048] Please see Figure 4 , Figure 8 , Figure 9 In one embodiment, the bed frame further includes a headboard 3, which is positioned above the bed frame 2. In some embodiments, the headboard 3 is connected to the support legs 23 via rods. Specifically, the rods of the headboard 3 can engage with screw holes on the support legs 23 to adjust the height of the headboard 3. When the user's room wall has a baseboard, the headboard 3 can be raised to a certain height above the ground, which can accommodate the baseboard. This installation allows the headboard to fit more snugly against the wall and prevents it from wobbling.
[0049] Please see Figures 4 to 3In one embodiment, the bed frame 2 includes a baffle 27, which is mounted on the first rod 21. Specifically, the shape of the baffle 27 matches the first rod 21 for engaging with it. When a mattress is placed on the bed frame 2, the baffle 27 on the first rod 21 effectively prevents the mattress from sliding and keeps it confined to the bed frame 2.
[0050] The advantages or beneficial effects of the above technical solutions include at least the following:
[0051] In the connector 1 provided in this application, the connector 1 includes a plug-in body 11 and a buffer body 12. The plug-in body 11 is installed inside the first rod 21, and the plug-in body 11 has a plug-in groove 111. The plug-in groove 111 matches the end of the second rod 22 for insertion into the second rod 22, thereby realizing the connection between the second rod 22 and the first rod 21. This connection method is simple and quick, which is beneficial to improving installation efficiency. The buffer body 12 is located at the lower end of the plug-in body 11. When the second rod 22 is subjected to external force and thus exerts force on the connector 1, the buffer body 12 deforms to buffer the pressure exerted by the second rod 22 on the plug-in body 11, thereby helping to extend the service life of the connector 1. At the same time, the structural design of the connector 1 ensures that the connector 1 can be stably inserted into the first rod 21 during the transportation of the bed frame, and it is not easy for it to fall off.
[0052] In the bed frame provided in this application, each component can be disassembled and packaged for easy transportation; the use of connector 1 to connect the first rod 21 and the second rod 22 facilitates rapid assembly of the bed frame 2 and improves installation efficiency.
[0053] The bed frame provided in this application can also flexibly adjust the height of the support legs 23 as needed. Multiple first screw holes 231 are provided on the support legs 23, and second screw holes 24 are provided on the side of the bed frame 2. Users can select the appropriate height of the first screw holes 231 and second screw holes 24 to secure them together, thereby achieving the purpose of adjusting the height of the support legs 23.
