Description

Technical Field

[0001] This utility model relates to a balance block packaging box, and more particularly to a balance block reel structure. Background Technology

[0002] The description in this section provides only background information related to the disclosure of this utility model and does not constitute prior art.

[0003] Vehicle wheel hubs, due to components such as air inflators or manufacturing errors, cannot achieve perfect weight balance. Therefore, as the vehicle runs, the increased wheel speed amplifies this imbalance, causing wheel vibration and steering wheel shaking. This not only affects ride comfort but also wears down the vehicle body, impacting its lifespan. Adding balance weights to the wheel hubs can solve this problem. To ensure precise balance, balance weights are typically lightweight, and multiple weights are used to achieve wheel hub balance. Existing balance weights are usually stacked in a cardboard box. The weights are long and rectangular, with multiple sub-units, and are used as needed, leading to frequent removal.

[0004] Existing counterweight packaging boxes typically require a plastic reel inside the box as a liner to facilitate winding the counterweights and unloading them by rotating the reel. However, the plastic reel is expensive and increases the weight of the entire box of counterweights, making it inconvenient for transportation.

[0005] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solutions of this utility model and facilitating understanding by those skilled in the art. It should not be assumed that these technical solutions are known to those skilled in the art simply because they have been described in the background section of this utility model.

[0011] A rotating ring is fitted around the second annular portion, and the balance block is wound around the rotating ring.

[0012] The first annular portion and the second annular portion are fixedly connected.

[0013] As a further description of the above technical solution, the outer wall of the first annular portion has an annularly arranged protrusion, which is used to abut against the inner wall of the second annular portion.

[0014] As a further description of the above technical solution, the number of protrusions is set to multiple, and the multiple protrusions are arranged at intervals along the extension direction of the first annular portion.

[0015] As a further description of the above technical solution, the protrusion is provided with an inclined side that slopes from the second mounting buckle toward the first mounting buckle, and the inclined side is used to abut against the inner wall of the second annular portion.

[0016] As a further description of the above technical solution, the length of the first annular portion is equal to the length of the second annular portion.

[0017] As a further description of the above technical solution, the length of the rotating ring is equal to the thickness of the space inside the housing.

[0020] As a further description of the above technical solution, the inner wall of the second annular portion has an annularly arranged snap-fit ​​portion, which is used to abut against the outer wall of the first annular portion.

[0021] As a further description of the above technical solution, the first annular portion and the second annular portion are interlocked, threaded, or glued together.

[0022] Based on the above technical solution, the beneficial effects of this utility model are as follows:

[0023] This utility model's balance weight reel structure allows for direct hole drilling in the housing, with the first and second mounting buckles interlocking via these holes.

[0036] Please see Figure 1-2 This embodiment provides a balance block reel structure for storing balance blocks, wherein the balance block reel structure includes:

[0037] The housing 1 has a first surface and a second surface that are disposed opposite to each other. A first mounting hole 13 is provided on the first surface of the housing 1, and a second mounting hole 14 is provided on the second surface of the housing 1. A pickup port 12 is provided on the side wall between the first surface and the second surface of the housing 1.

[0038] The first mounting buckle 2 includes a first annular portion 21 and a first flange portion 22 connected together. The first annular portion 21 is inserted into the housing along the first mounting hole 13, and the first flange portion 22 is in contact with the first surface of the housing 1.

[0039] The second mounting buckle 3 includes a second annular portion 31 and a second flange portion 32 connected together. The second annular portion 31 is inserted into the housing 1 along the second mounting hole 14 and sleeved on the outside of the first annular portion 21. The second flange portion 32 is in contact with the second surface of the housing 1.

[0040] Rotating ring 4 is sleeved outside the second annular part 31, and the balance block is wound around the rotating ring 4.

[0041] The first annular portion 21 and the second annular portion 31 are fixedly connected, which can be done by, but is not limited to, a snap-fit, a threaded connection or an adhesive bonding.

[0042] With the above structure, during installation, the operator can first assemble the housing 1 and pre-place the rotating ring 4 between the first mounting hole 13 and the second mounting hole 14 of the housing 1. Then, the first mounting buckle 2 is installed towards the first mounting hole 13. Specifically, the first annular portion 21 of the first mounting buckle 2 is inserted with one side facing the first mounting hole 13, so that the first annular portion 21 is completely inserted into the housing 1. At the same time, the second mounting buckle 3 is installed towards the second mounting hole 14. Specifically, the second annular portion 31 of the second mounting buckle 3 is inserted with one side facing the second mounting hole 14, so that the second annular portion 31 is completely inserted into the housing 1, and the second annular portion 31 is fitted onto the outer wall surface of the first annular portion 21. The first annular portion 21 and the second annular portion 31 can further form a snap-fit, threaded connection, or adhesive bond relationship. Meanwhile, the rotating ring 4 is also fitted onto the outside of the second annular portion 31 of the second mounting buckle 3. Therefore, the balance weight can be wound around the rotating ring 4 in the positive direction.

[0043] During use, a portion of the balance block needs to be pulled from the rotating ring 4 to the pickup port 12 of the housing 1. After pulling out the required amount, the portion to be used is cut off. During the pulling process, the balance block drives the rotating ring 4 to rotate. The rotating ring 4 rotates relative to the second annular portion 31 of the second mounting buckle 3 and generates sliding friction with it. That is to say, at least in this embodiment, the inner diameter of the rotating ring 4 needs to be larger than the outer diameter of the second annular portion 31, so as to avoid the second annular portion 31 from jamming the rotating ring 4.

[0044] The installed balance block reel structure has its first flange 22 of the first mounting buckle 2 tightly fitted to one side of the first surface of the housing 1, and its second flange 32 of the second mounting buckle 3 tightly fitted to one side of the second surface of the housing 1. Therefore, the first mounting buckle 2 and the second mounting buckle 3 effectively act as bridging supports, being fixed and stable, using the entire housing 1 to provide support for itself, resulting in better stability. Specifically, in this embodiment, the first mounting buckle 2 and the second mounting buckle 3 cooperate with each other to form a tight connection and are stably fitted into the housing 1. This makes the housing 1 a support that directly supports the first mounting buckle 2 and the second mounting buckle 3, and its stability is more stable than that of a typical separate installation structure, less prone to loosening.

[0045] In the above embodiments, holes can be directly drilled in the housing 1, and the first mounting buckle 2 and the second mounting buckle 3 can be fastened to each other through the holes, resulting in low cost and reduced overall box weight. Specifically, during installation, the first mounting buckle 2 is inserted from the direction of the first mounting hole 13, and the second mounting buckle 3 is inserted from the direction of the second mounting hole 14, and is fitted over the first annular portion 21 of the first mounting buckle 2, so that the first mounting buckle 2 and the second mounting buckle 3 directly abut against the housing 1, using the entire housing 1 as a support to bear the weight of the balance weight wound between them. Therefore, there is no need for an additional liner inside the housing 1 for fixing or winding the balance weight, making the overall structure lighter and reducing costs. The above structure is also easier to assemble from an installation perspective, requiring only one insertion and one fastening, which can improve shipping efficiency.

[0046] From a size perspective, the first mounting buckle 2 and the second mounting buckle 3 are limited in size, thus providing more installation space for the balance block and facilitating a larger single-box load capacity.

[0047] The outer wall of the first annular portion 21 has an annularly arranged protrusion 23, which is used to abut against the inner wall of the second annular portion 31. As a plastic part integrally formed with the first annular portion 21, the protrusion 23 specifically serves to elastically engage the second annular portion 31.

[0048] The number of protrusions 23 is set to multiple, such as Figure 1 As shown, in this embodiment, the number of protrusions 23 is set to three, and the three protrusions 23 are arranged at intervals along the extending direction of the first annular portion 21. Therefore, by providing multiple protrusions 23 for engagement, the engagement of the second annular portion 31 can be made more stable.

[0049] The protrusion 23 is provided with a beveled edge that slopes from the second mounting buckle 3 toward the first mounting buckle 2. The beveled edge is used to abut against the inner wall of the second annular portion 31. That is to say, in this embodiment, the actual cross-section of the protrusion 23 is set as a triangle, specifically a right triangle. Its shape is easy to process, and the bevel itself can guide the fitting of the second annular portion 31. Its shape is similar to a barb, which makes it easy to insert the second annular portion 31, but not conducive to the disengagement of the second annular portion 31. Therefore, it can strengthen the snap-fit ​​strength.

[0050] The length of the first annular portion 21 is equal to the length of the second annular portion 31. In the housing 1 of this embodiment, the snap-fit ​​combination of the first mounting buckle 2 and the second mounting buckle 3 can just cover the space between them, thus maintaining maximum material strength.

[0051] The length of the rotating ring 4 is equal to the thickness of the space inside the housing 1. Therefore, the rotating ring 4 provides better support for the balance block and has a larger contact area.

[0052] An observation hole 11 is provided on the shell 1. The observation hole 11 is located on the first or second surface of the shell 1 and is used to monitor the balance of the balance block inside the shell 1. The observation hole 11 can be set as a thin strip in the shape of an oblong hole extending radially, thus enabling observation over a large range.

[0053] The first annular portion 21 and the first flange portion 22 are integrally formed, as are the second annular portion 31 and the second flange portion 32. The integral structure offers high strength, and in this embodiment, the aforementioned snap-fit ​​structure can be made of plastic or lightweight alloy, resulting in a compact structure.

[0054] Similar to the protrusion 23 in the first annular portion 21 described above, the inner wall of the second annular portion 31 has an annularly arranged snap-fit ​​portion for abutting against the outer wall of the first annular portion 21. Specifically, in this embodiment, the inwardly protruding snap-fit ​​portion is used to generate friction against the outer wall of the first annular portion 21 and establish a snap-fit ​​relationship.

[0055] Of course, in another embodiment, the protrusion 23 and the snap-fit ​​portion can coexist and cooperate with each other to achieve the effect of snapping together, so as to achieve the maximum snap-fit ​​stability.

[0056] The above-disclosed content is only a preferred and feasible embodiment of the present utility model, and is not intended to limit the scope of the patent application of the present utility model. Therefore, all equivalent technical changes made using the contents of the present utility model specification and drawings are included in the scope of the patent application of the present utility model.

[0057] The various embodiments in this specification are described in a progressive manner. The same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on describing the differences from other embodiments.

[0058] Although this application has been described by way of examples, those skilled in the art will know that this application has many modifications and variations without departing from the spirit of this application, and it is intended that the appended embodiments include these modifications and variations without departing from this application.
