Description

Technical Field

[0001] This invention relates to the field of shelf trays, and more specifically, to a loading platform with a connecting sleeve. Background Technology

[0002] Shelf supports are small accessories used in cabinet-style furniture to support the middle partitions, and are commonly found in panel furniture, especially wardrobes, cabinets, shoe cabinets, bookcases, and other cabinet-style layered furniture. Currently, conventional wooden shelf supports on both sides need to be fixed to the side panels of the cabinet and the shelf itself using self-tapping screws. The current problem is that the main types of engineered wood used to make wooden shelves are medium-density fiberboard (MDF) and particleboard. MDF, due to its fiber material laying and gluing process, is prone to cracking when self-tapping screws are forced into its ends. Particleboard, due to its particle laying and gluing process, has a relatively loose middle layer and poor nail-holding power.

[0003] Patent document 1 (publication number: CN106510255A) discloses a concealed shelf holder, including a mounting sleeve. The mounting sleeve is cylindrical in shape, with a vertically penetrating connection port on its side wall. The mounting sleeve is made of plastic, while the mounting base and locking mechanism are metal. The surface of the mounting sleeve has an expansion texture. The mounting sleeve is vertically pressed into the first mounting hole of the shelf, exposing the connection port to one side of the shelf through the first mounting hole, and the lower end of the mounting sleeve is exposed below the shelf through the first mounting hole. The support rod on the mounting base is inserted into the second mounting hole of the side plate. Holding the shelf with the mounting sleeve installed, gently pressing down, the mounting sleeve is pressed into the mounting base. The aforementioned shelf support uses an installation sleeve with an expansion texture to connect the shelf and the side panel together. However, both ends of the expansion texture are fixed to the installation sleeve. Furthermore, the outer surface of the expansion texture still protrudes from the surface of the installation sleeve when it is not expanded. This will cause the maximum outer diameter of the installation sleeve to increase when the installation sleeve is installed into the shelf, increasing the friction between the installation sleeve and the shelf, increasing the installation resistance, and thus causing damage to the shelf or the installation sleeve.

[0004] Patent document 2 (publication number: CN210696718U) discloses a shelf support, including a first support plate and a second support plate. The first support plate is positioned horizontally, and the second support plate is positioned vertically. The upper part of the first support plate is connected to the second support plate, and the second support plate is fixed to the board material. In this design, the shelf is essentially just placed on the shelf support, and the connection between the shelf and the shelf support is loose and detachable, resulting in an unstable installation.

[0016] Compared with the prior art, the cargo platform with connecting sleeve provided by the present invention achieves at least the following beneficial effects:

[0017] The spring sheet of the present invention is installed on the connecting sleeve. Since one end of the spring sheet is a movable end, the spring sheet can be elastically bent into the inside of the connecting sleeve, so that the outer surface of the spring sheet is recessed into the outer surface of the connecting sleeve, thereby reducing the maximum diameter of the outer surface of the connecting sleeve, reducing the resistance encountered by the connecting sleeve when inserted into the shelf, thereby reducing the friction between the connecting sleeve and the shelf, reducing the installation resistance, and avoiding damage to the shelf or the connecting sleeve.

[0018] Of course, any product implementing this invention does not necessarily need to achieve all of the above technical effects simultaneously.

[0032] To address the aforementioned technical problems, this invention proposes a cargo platform with a connecting sleeve, which will be described in detail below.

[0033] refer to Figures 1 to 4 As shown, Figure 1 This is a schematic diagram of the structure of a loading platform with a connecting sleeve provided by the present invention; Figure 2 This is a three-dimensional structural schematic diagram of a connecting sleeve provided by the present invention; Figure 3 This is a schematic diagram of the main structure of a connecting sleeve provided by the present invention; Figure 4 yes Figure 3A cross-sectional structural diagram of section A-A'; This invention provides a loading platform with a connecting sleeve, including: a shelf support 7, and a connecting sleeve 2 sleeved around the shelf support 7; the loading platform also includes a shelf 1 sleeved around the connecting sleeve 2; the shelf 1 is installed on the side panel 10 of the cabinet; multiple shelf supports 7 and connecting sleeves 2 are evenly installed circumferentially between the shelf 1 and the side panel 10; the shelf support 7 is fixedly connected to the side panel 10 of the cabinet by screws; from the inner circle to the outer circle, the sequence is shelf support 7, connecting sleeve 2, and shelf 1; during installation, the connecting sleeve 2 is first inserted into the shelf 1, and the shelf support 7 is fixed to the side panel of the cabinet at the same time, and then the connecting sleeve 2 and the shelf support 7 are inserted; the connecting sleeve 2 has an internal accommodating shelf support 7. The cylindrical body of the chamber has an insertion port 3 extending axially along the connecting sleeve 2, a connecting port 4 extending radially along the connecting sleeve 2, and at least one spring plate mounting port 5 extending radially along the connecting sleeve 2 on its side wall. In this embodiment, there are two spring plate mounting ports 5, which are arranged circumferentially along the connecting sleeve 2. The chamber of the connecting sleeve 2, the insertion port 3, the connecting port 4, and the spring plate mounting ports 5 are connected. The shelf support 7 is inserted into the cylindrical body of the connecting sleeve 2 through the insertion port 3 and the connecting port 4. Each spring plate mounting port 5 contains a spring plate 6. The spring plate 6 is elastic, with one end of the spring plate 6 being a fixed end fixedly connected to the edge of the spring plate mounting port 5, and the other end being a movable end that can move radially along the cylindrical body of the connecting sleeve 2. During the springing process, the trajectory of the movable end of the spring plate 6 is an arc rotating with the fixed end as the center. The outer circumferential wall of the spring piece 6 is press-fitted with the shelf plate 1, allowing the spring piece 6 to spring back. The shelf plate support 7 is inserted into the connecting sleeve 2, causing the movable end of the spring piece 6 to move to one side of the shelf plate 1 and insert into the surface of the shelf plate 1, making the shelf plate and connecting sleeve 2 more firmly fixed, thus achieving the tensioning and locking effect. Multiple spring pieces 6 are evenly distributed along the circumference of the connecting sleeve 2. In this embodiment, there are two spring pieces 6, which are positioned opposite each other on both sides of the connecting port 4. This invention does not impose a specific limit on the number of spring pieces 6; it can be designed according to the actual installation conditions.

[0034] refer to Figure 4 and Figure 5 As shown, Figure 5This is a schematic diagram of a three-dimensional structure with inverted teeth provided by the present invention. In some optional embodiments, the movable end of the spring piece 6 is located on the side away from the connection port 4, and the fixed end of the spring piece 6 is located on the side close to the connection port 4. After the connecting sleeve 2 is inserted into the shelf 1, the movable end of the spring piece 6 is pressed by the shelf 1 and squeezed into the interior of the connecting sleeve 2. The movable end of the spring piece 6 protrudes from the inner surface of the connecting sleeve 2, reducing the space inside the connecting sleeve 2 at the corresponding position of the spring piece 6. The fixed end of the spring piece 6 is fixedly connected to the spring piece mounting port 5, and the position of the fixed end remains unchanged. Therefore, the interior space of the connecting sleeve 2 is not convenient here. The side of the spring piece 6 that is closer to the connection port 4 is connected to the connecting sleeve 2. That is to say, when the shelf support 7 is inserted into the connecting sleeve 2, the shelf support 7 will be inserted from the larger interior space of the connecting sleeve 2 to the smaller interior space. The interior of the connecting sleeve 2 is equivalent to a conical structure, which makes the insertion of the shelf support 7 more convenient and effortless.

[0035] Specifically, the loading platform also includes a shelf 1 sleeved around the connecting sleeve 2; the spring piece 6 includes a shelf contact surface that abuts against the shelf 1; at least one inverted tooth 9 is provided on the shelf contact surface; the inverted tooth 9 is arranged along the axial direction of the connecting sleeve 2. When the shelf support 7 is inserted into the connecting sleeve 2, the movable end of the spring piece 6 will move towards the shelf contact surface. In conventional shelves 1, the sidewalls of the shelf 1 often have a certain degree of flexibility. The movement of the spring piece 6 causes the inverted tooth 9 to insert into the shelf 1, further strengthening the fixed connection between the connecting sleeve 2 and the shelf 1.

[0036] Specifically, there is a gap between two adjacent inverted teeth 9. The gap between two adjacent inverted teeth 9 allows each inverted tooth 9 to be inserted into the shelf 1 individually, reducing the contact area between the inverted tooth 9 and the shelf 1, increasing the pressure exerted by the inverted tooth 9 on the shelf 1, and allowing the inverted tooth 9 to be inserted into the shelf 1 more smoothly, saving the force required to insert the shelf support 7.

[0037] Specifically, the reverse teeth 9 are inclined and include a tooth root 91 fixedly connected to the spring piece 6 and a tooth tip 92 fixedly connected to the tooth root 91. The tooth root 91 is located on the side away from the connection port 4, and the tooth tip 92 is located on the side close to the connection port 4. The spring piece 6 is designed with an inclined structure to facilitate the insertion of the connecting sleeve 2 into the shelf plate 1. The reverse teeth 9 on the spring piece 6 will not obstruct the shelf plate from being fitted. When the connecting sleeve and the shelf plate are installed, the reverse teeth are in the forward direction, and when the connecting plate and the shelf plate are disassembled, the reverse teeth are in the reverse direction. At the same time, it can also prevent the connecting sleeve from loosening or falling off from the shelf plate.

[0038] Specifically, a tooth seat 93 is provided between the spring 6 and the tooth root 91. One end of the tooth seat 93 is fixedly connected to the shelf contact surface of the spring 6, and the other end is fixedly connected to the side of the tooth root 91 away from the tooth tip 92. The volume of the tooth tip 92, tooth root 91, and tooth seat 93 increases sequentially. The tooth seat 93 has a larger area, which allows the reverse tooth to be more firmly fixed on the spring 6, preventing it from falling off the spring due to the pressure of the shelf support 7 and the weight of the shelf 1 over a long period of time. This strengthens the firmness of the connecting sleeve and the shelf, improves the stability of the fixed connection between the connecting sleeve and the shelf, and thus improves the firmness between the shelf and the cabinet and the stability of their fixed connection.

[0039] Specifically, the thickness of the toothed seat 93 in the radial direction of the connecting sleeve 2 is smaller on the side closer to the connecting port 4 than on the side farther away from the connecting port 4. The thickness of the toothed seat 93 in the radial direction of the connecting sleeve 2 gradually changes, with the outer surface of the toothed seat 93 smoothly transitioning from a thicker area to a thinner area. The thickness of the toothed seat 93 differs on both sides, becoming thicker the farther away from the connecting port 4. As the thickness of the toothed seat 93 increases, the internal space of the connecting sleeve 2 is reduced, increasing the depth of the inverted teeth insertion into the shelf plate, improving the tightness between the shelf plate support 7, the connecting sleeve 2, and the shelf plate 1, and enhancing the stability of the fixation between the three. The gradual increase in the thickness of the toothed seat 93 also makes the interior of the connecting sleeve 2 equivalent to a conical structure, allowing the shelf plate support 7 to be inserted from the larger internal space of the connecting sleeve 2 to the smaller internal space, making the insertion of the shelf plate support 7 more convenient and effortless.

[0040] Specifically, the toothed seat 93 is a long strip extending circumferentially along the cylindrical body of the connecting sleeve 2, with multiple inverted teeth 9 arranged parallel to each other. The toothed seat 93 extends circumferentially along the cylindrical body of the connecting sleeve 2, which is equivalent to the toothed seat 93 extending along the direction of the connecting sleeve insertion into the layer plate. During the insertion process, the toothed seat 93 acts as a guide rib, making the insertion of the connecting sleeve 2 more convenient and effortless.

[0041] Continue to refer to Figure 2 As shown, in some optional embodiments, a support plate 8 is provided on the side of the connecting sleeve 2 opposite to the insertion port 3 along its axial direction; the circumferential edge of the support plate 8 is fixedly connected to the circumferential edge of the connecting sleeve 2; the inner wall shape of the support plate 8 matches the shape of the shelf support 7. The connecting sleeve 2 is sleeved around the outer periphery of the shelf support 7, and the outer surface of the shelf support 7 abuts against the support plate 8.

[0042] Continue to refer to Figure 1 As shown, in some optional embodiments, the layer plate 1 is provided with a sleeve mounting hole (not shown in the figure) for inserting the connecting sleeve 2, and the connecting sleeve 2 is inserted into the sleeve mounting hole; the tooth tip is interference-fitted with the inner wall of the sleeve mounting hole along the circumference of the connecting sleeve 2.

[0043] refer to Figure 6 As shown, Figure 6This is a three-dimensional structural schematic diagram of a shelf support provided by the present invention. In some optional embodiments, the shelf support 7 includes a base plate 13. The base plate 13 is provided with at least one connecting block 11. In this embodiment, the number of connecting blocks 11 is one. The present invention does not specifically limit the number of connecting blocks 11. The number of connecting blocks 11 is specifically set according to the circumferential length of the actually installed shelf 1. The more connecting blocks 11 there are, the more fixing points between the shelf 1 and the cabinet, and the more securely the shelf 1 is fixed and less prone to loosening. The connecting block 11 is connected to the side plate 10 of the cabinet by bolts / screws. The connecting block 11 is provided with a stepped through hole 12. The stud part of the bolt / screw passes through the stepped through hole 12 and is screwed into the side plate 10 of the cabinet to be fixedly connected to the cabinet. The nut part of the bolt / screw is pressed against the surface of the stepped through hole 12. The connecting block 11 is clamped between the nut part of the bolt / screw and the side plate 10 of the cabinet, thereby realizing the fixed connection between the shelf 1 and the side plate 10 of the cabinet through the shelf support 7.

[0044] As can be seen from the above embodiments, the loading platform with connecting sleeve provided by the present invention achieves at least the following beneficial effects:

[0045] The spring sheet of the present invention is installed on the connecting sleeve. Since one end of the spring sheet is a movable end, the spring sheet can be elastically bent into the inside of the connecting sleeve, so that the outer surface of the spring sheet is recessed into the outer surface of the connecting sleeve, thereby reducing the maximum diameter of the outer surface of the connecting sleeve, reducing the resistance encountered by the connecting sleeve when inserted into the shelf, thereby reducing the friction between the connecting sleeve and the shelf, reducing the installation resistance, and avoiding damage to the shelf or the connecting sleeve.

[0046] While specific embodiments of the invention have been described in detail by way of examples, those skilled in the art should understand that the examples are for illustrative purposes only and not intended to limit the scope of the invention. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the invention.
