Description

Technical Field

[0001] This utility model relates to the field of transport packaging, and in particular to a server pallet buffer block and a server pallet. Background Technology

[0002] Ensuring the safe and undamaged transport of server products has become a key concern for many companies. To withstand impacts and vibrations during transit, server racks are typically secured directly to specially designed pallets, which provide effective cushioning and protection. This practice largely guarantees product safety during transport and significantly reduces the incidence of accidents caused by improper transportation.

[0003] Unlike conventional wooden pallets, server pallets are typically double-layered with buffer blocks between the two layers. The buffer blocks for server racks, which are widely used in the market today, are made of high-density integral foamed polyethylene (EPE).

[0004] Firstly, due to current widespread environmental protection requirements, the use of this plastic material is gradually being restricted. Secondly, a significant drawback of EPE material is its high creep rate. This means that during long-term storage, EPE pallet supports are prone to compression deformation, leading to a significant reduction in their cushioning effect. This poses a potential risk to the transportation safety of the entire rack product. If the cushioning effect is weakened during long-distance transportation, the rack product is more susceptible to damage when encountering unexpected impacts and vibrations, which will undoubtedly shorten the product's lifespan and even affect its functionality.

[0005] Another issue is that when the center of gravity of the rack is off-center, the forces on each pallet support may be uneven, which can easily cause the pallets to tilt. In this tilted state, the entire rack is highly likely to tip over during transportation, leading to serious accidents. Summary of the Invention

[0006] This invention addresses the issues of creep failure and pallet tilting that arise when using high-density integrated foamed polyethylene for cushioning in current server transport pallets. It provides a safer and more stable server pallet cushioning block.

[0007] To solve the above problems, the technical solution adopted by this utility model is as follows: a server pallet buffer block, including a block body, the block body including a base and a movable plug, the base having a hollow cavity inside, the hollow cavity being open on the top surface of the base, the lower end of the movable plug being inserted into the base to form a cylinder structure, the base also having an air valve connected to the hollow cavity; the bottom of the base having a lower connecting block, and the top of the movable plug having an upper connecting block.

[0008] This design incorporates a small cylinder-structured buffer block. The block body and the movable plug utilize air pressure support to provide support and buffering for the upper and lower layers of the pallet. It offers excellent long-term support retention. Additionally, an air valve is incorporated to inflate the hollow cavity inside the base after extended use, eliminating creep failure. The air valve also allows for adjustment of the internal pressure of the hollow cavity, altering the support effect to address server rack imbalances and ensuring the pallet remains level and stable at all times.

[0009] As a preferred implementation of the server stack buffer block, the inner edge of the top open surface of the base is provided with a circular boss, the outer diameter of the movable plug is adapted to the inner diameter of the circular boss, and the bottom outer periphery of the movable plug is provided with a lower panel, the outer diameter of the lower panel being larger than the inner diameter of the circular boss.

[0010] A piston structure is formed between the base and the movable plug to prevent them from coming off.

[0011] As a preferred implementation of the server stack buffer block, the outer peripheral surface of the lower panel is provided with a rubber ring, and the outer peripheral surface of the rubber ring is in close contact with the inner wall of the hollow cavity.

[0012] By incorporating a rubber ring, the airtightness between the movable plug and the hollow cavity inside the base is improved, ensuring the stability of the support force and enhancing the support effect.

[0013] As a preferred implementation of the server stack buffer block, the movable plug has a top panel on its outer periphery, and the upper connecting block is installed on the top surface of the top panel. Connecting the top panel to the upper connecting block reduces pressure on the upper connecting block while increasing the connection area, resulting in more stable support.

[0014] As a preferred implementation of the server stack buffer block, both the upper and lower connecting blocks are made of wood. The use of wood for both the upper and lower connecting blocks provides good energy absorption and further enhances the buffering capacity.

[0015] As a preferred implementation of the server pallet buffer, the outer circumferential surface of the movable plug is provided with scale lines along the height direction. This allows for a direct visual indication of the degree of concavity of the movable plug under pressure, facilitating the replenishment of gas within the hollow cavity by staff to level the pallet.

[0016] As a preferred implementation of a server stack buffer block, the air valve includes a cylindrical body with a vent hole in it. The upper end of the vent hole connects to the interior of a hollow cavity, and a one-way barrier membrane is provided at the upper end of the vent hole. The air valve adopts a one-way valve structure, which facilitates inflation adjustment and provides flexible use. It also reduces the structural complexity of the product and lowers manufacturing and usage costs.

[0017] As a preferred implementation of the server stack buffer block, the upper end of the cylindrical body is provided with a conical boss, the circular bottom surface of which is connected to the top surface of the cylindrical body, and the diameter of the circular bottom surface of the conical boss is larger than the diameter of the cylindrical body; the lower end of the cylindrical body is provided with a lower boss, the outer diameter of which is larger than the outer diameter of the cylindrical body. The top of the air valve is conical, allowing it to be directly inserted into the base. Furthermore, the air valve adopts a structure that is thicker at both ends and thinner in the middle, making it more stable when embedded in the base.

[0018] As a preferred implementation of the server stack buffer block, the conical boss has multiple inverted U-shaped through holes along the circumference inside. One end of the inverted U-shaped through hole is located on the outer circumferential surface of the conical boss, and the other end is connected to the upper end of the vent hole in the cylindrical body.

[0019] On the other hand, this utility model also provides a server stack, including an upper plate and a lower plate, with a plurality of the above-mentioned server stack buffer blocks provided between the upper plate and the lower plate, and the plurality of server stack buffer blocks are distributed in a rectangular array.

[0020] It also includes an air source and an air pressure controller. The air pressure controller is connected to the air source signal. Each of the hollow cavities of the server pallet buffer is equipped with an air pressure sensor. Multiple air pressure sensors are connected to the air pressure controller signal. The air source is connected to the air valves of multiple server pallet buffers.

[0021] As can be seen from the above technical solutions, the advantages of this utility model are as follows: This solution designs a piston-type buffer block, which uses air pressure for cushioning and support. It provides good support over long-term use, eliminates creep failure issues, and maintains better support performance. Simultaneously, the hollow cavity of the base is equipped with an air valve, which replenishes the gas after prolonged use, maintaining stable air pressure. The air valve also allows for unified pressure adjustment of multiple buffer blocks to accommodate server rack imbalances. The air valve is a one-way valve, simple in structure, easy to install, convenient to use, and has low manufacturing and operating costs. The air valve has a conical upper end and an overall structure that is thicker at both ends and thinner in the middle, making installation convenient and secure. Furthermore, the server pallet provided by this utility model, using the aforementioned buffer blocks, provides excellent support for the server rack. It also incorporates air pressure sensors that intelligently adjust the internal air pressure of each buffer block to adapt to server rack imbalances, resulting in more stable support, preventing tipping, and ensuring the safe transport of the server rack.

[0031] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0032] like Figure 1 , 2As shown, a server pallet buffer includes a main body, which includes a base 1 and a movable plug 2. The bottom of the base 1 has a lower connecting block 3 for connecting the lower panel of the pallet. The top of the movable plug 2 has an upper connecting block 4 for connecting the upper panel of the pallet. Further, both the upper and lower connecting blocks are made of wood. The base 1 has a hollow cavity inside, open at the top surface. The lower end of the movable plug 2 is inserted into the base 1, thus forming a cylinder structure between the base 1 and the movable plug 2. Specifically, as shown... Figure 2 As shown, the inner edge of the top open surface of the base 1 is provided with a circular boss 1-1. The outer diameter of the movable plug 2 is adapted to the inner diameter of the circular boss 1-1. The fit requirement here is that, while ensuring a certain airtightness, the two can slide relative to each other under the action of external force. The bottom outer periphery of the movable plug 2 is provided with a lower panel 2-1. The outer diameter of the lower panel 2-1 is larger than the inner diameter of the circular boss 1-1, so that the lower end of the movable plug 2 is restricted in the hollow cavity and will not be pulled upward. The outer peripheral surface of the lower panel 2-1 is provided with a rubber ring 6. The outer peripheral surface of the rubber ring 6 is in close contact with the inner wall of the hollow cavity to ensure the airtight effect. The top outer periphery of the movable plug 2 is provided with an upper panel 2-2, and the upper connecting block 4 is installed on the top surface of the upper panel 2-2.

[0033] The air valve is a one-way valve structure, specifically, as shown below. Figure 3 , 4 As shown, the air valve 5 includes a cylindrical body 8 with a vent hole in it. The upper end of the vent hole connects to the interior of a hollow cavity, and a one-way barrier film is provided at the upper end of the vent hole. A conical boss 9 is provided at the upper end of the cylindrical body 8, with its circular bottom surface connected to the top surface of the cylindrical body 8. The diameter of the circular bottom surface of the conical boss 9 is larger than the diameter of the cylindrical body 8. A lower boss 10 is provided at the lower end of the cylindrical body 8, with its outer diameter larger than the outer diameter of the cylindrical body 8. Multiple inverted U-shaped through holes are provided circumferentially inside the conical boss 9, with one end of each inverted U-shaped through hole located on the outer circumferential surface of the conical boss 9 and the other end connected to the upper end of the vent hole in the cylindrical body 8.

[0034] This embodiment designs a piston-type buffer block that uses air pressure for cushioning and support. It provides excellent support over long-term use, eliminates creep failure issues, and maintains its support effectiveness. Simultaneously, an air valve is installed in the hollow cavity of the base, allowing for replenishment of gas after prolonged use to maintain stable air pressure. The air valve also enables unified pressure adjustment across multiple buffer blocks to accommodate imbalances in the server rack's center of gravity. The air valve is a one-way valve, simple in structure, easy to install, convenient to use, and low in manufacturing and operating costs. The valve has a conical top and an overall structure that is thicker at both ends and thinner in the middle, ensuring convenient and secure installation.

[0035] Example 2

[0036] This embodiment provides a server pallet buffer block, whose structure is basically the same as that of Embodiment 1, including a base 1, a movable plug 2, a lower connecting block 3, an upper connecting block 4, and an air valve. The difference between this embodiment and Embodiment 1 is that, in this embodiment, the outer circumferential surface of the movable plug 2 is provided with a scale line 7 along the height direction. Therefore, this embodiment can more intuitively show the lower limit of the buffer block under the pressure of the server rack, so as to provide reference for the staff and adjust the level of the pallet.

[0037] Example 3

[0038] This embodiment provides a server stack, including an upper plate 11 and a lower plate 12. Multiple server stack buffer blocks of Embodiment 1 and / or Embodiment 2 are provided between the upper plate 11 and the lower plate 12. The multiple server stack buffer blocks are distributed in a rectangular array. The bottom surface of the upper plate 11 may also be provided with a frame wood 13. The upper panel of the buffer block is connected to the frame wood 13. The top surface of the upper plate 11 is also provided with a reinforcing plate 14, which may be made of steel plate and / or fiberboard.

[0039] Furthermore, the server stack in this embodiment also includes an air source and an air pressure controller. The air pressure controller is connected to the air source via a signal. Air pressure sensors are respectively installed in the hollow cavities of the server stack buffer blocks. Multiple air pressure sensors are connected to the air pressure controller via a signal. The air source is connected to the air valves of multiple server stack buffer blocks via air circuits.

[0040] In this embodiment, when the server pallet is in use, after the server rack is placed, each pressure sensor detects the internal pressure of the corresponding server pallet buffer block. The greater the increase in pressure, the greater the pressure drop of the buffer block, indicating that the entire pallet is tilted. At this time, the pressure controller controls the air source to inflate the buffer block, raising it and restoring the pallet to a horizontal state. Simultaneously, the pressure sensors can also monitor the air pressure of the buffer block when it is unloaded. If the unloaded air pressure decreases, it indicates that gas has escaped from the buffer block due to prolonged use. At this time, the air source replenishes gas into the buffer block.

[0041] The server rack provided by this utility model uses the above-mentioned buffer blocks, which provide good support for the server rack. At the same time, it is equipped with air pressure sensors, which can intelligently adjust the internal air pressure of each buffer block to adapt to the situation of unbalanced center of gravity of the server rack, making the support more stable, preventing tipping, and ensuring the safe transportation of the server rack.

[0042] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
