Description

Technical Field

[0001] This utility model relates to the field of fastener technology, and more specifically, to a furniture nail. Background Technology

[0002] Self-tapping screws with support blocks screwed into the bottom of furniture support legs effectively raise the clamps while also providing anti-slip and wear-resistant properties. Commercially available screws or bare nails of this type offer a fixed, non-adjustable height, limiting their use and resulting in poor overall performance. Therefore, this invention proposes a furniture nail. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a furniture nail that is height-adjustable and easy to install.

[0004] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows: The furniture nail involved in this utility model includes a nail rod with threads on its outer wall surface, one end of the nail rod has a self-tapping part, the other end of the nail rod has a support part, the end of the support part facing away from the self-tapping part is provided with a centrally located plum blossom groove, a shim ring is fitted on the nail rod, a plurality of shim support feet arranged at equal height are distributed around one end face of the shim ring, and the end of the support part facing the self-tapping part is provided with support foot grooves that match the shim support feet and are for embedding.

[0005] The present invention is further configured such that: a groove is provided at one end of the support part facing away from the self-tapping part, and the plum blossom groove is provided at the bottom of the groove.

[0006] The present invention is further configured such that a soft rubber pad is attached to one end of the support portion facing away from the self-tapping portion.

[0007] The present invention is further configured such that the included angle between two adjacent raised support feet is equal.

[0008] The present invention is further configured such that: the support part and the nail rod are an integral structure; the self-tapping part and the nail rod are an integral structure.

[0009] The present invention is further configured such that the support portion has a rotating structure.

[0010] In summary, this utility model has the following beneficial effects: 1. It can be quickly screwed onto the bottom of furniture support legs to serve as a shim and prevent slipping.

[0011] 2. The height of the shim is selectable, allowing for flexible use. Attached Figure Description

Detailed Implementation

[0013] To enable those skilled in the art to better understand the technical solution of this utility model, the preferred embodiments of this utility model are described below in conjunction with specific examples. However, it should be understood that these descriptions are only for further illustrating the features and advantages of this utility model, and not for limiting the patent claims of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.

[0014] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0015] Example 1 See Figures 1 to 4 As shown, the furniture nail involved in this embodiment includes a nail rod 1 with threads on its outer wall surface, one end of the nail rod 1 has a self-tapping part 2, and the other end of the nail rod 1 has a support part 3. The end of the support part 3 facing away from the self-tapping part is provided with a centrally located plum blossom groove 4. A shim ring 5 is fitted on the nail rod 1, and a plurality of shim legs 6 arranged at equal height are distributed around one end of the shim ring 5. The end of the support part 3 facing the self-tapping part is provided with a shim groove 7 that matches the shim legs and is for embedding.

[0016] Furthermore, the support part 3 is provided with a sink groove 8 at one end facing away from the self-tapping part, and the plum blossom groove 4 is provided at the bottom of the sink groove 8.

[0017] Furthermore, the included angle between any two adjacent raised support legs 6 is equal.

[0018] Furthermore, the support part 3 and the nail rod 1 are an integral structure; the self-tapping part 2 and the nail rod 1 are an integral structure.

[0019] Furthermore, the support portion 3 has a rotating structure.

[0020] In this embodiment, the furniture nail can be installed at three different heights when it is positioned at the bottom of the furniture support leg. First, remove the shim ring 5 from the nail rod 1 and screw it on until the end of the support part 3 facing the self-tapping part 2 is flush with the bottom of the furniture support leg. Second, install the shim ring 5 on the nail rod 1 until the raised leg 6 is recessed into the leg groove 7, and screw it on until the shim ring 5 is clamped between the furniture support leg and the support part 3. Third, install the shim ring 5 on the nail rod 1 until the raised leg 6 is not recessed into the leg groove 7, with the raised leg 6 facing away from the support part 3, and screw it on until the shim ring 5 is clamped between the furniture support leg and the support part 3.

[0021] Among them, the first type has the lowest installation height, the second type has the next lowest, and the third type has the highest. The installation height of the second type is higher than that of the first type by the thickness of the shim ring 5; the installation height of the third type is higher than that of the second type by the height of the shim support 6.

[0022] The setting of the sink trough 8 allows the plum blossom groove 4 to be buried within it, preventing the burrs at the opening of the plum blossom groove 4 from protruding from the bottom of the support part 3, thus making the bottom of the support part 3 flat and smooth.

[0023] Example 2 See Figures 1 to 4 As shown, the furniture nail involved in this embodiment is further configured, based on embodiment 1, with a soft rubber pad 9 attached to one end of the support part 3 facing away from the self-tapping part.

[0024] In this embodiment, the soft rubber pad 9 serves as a padding material, while also providing elevation and anti-slip functions.

[0025] The furniture nail involved in this utility model can be quickly screwed onto the bottom of the support legs of furniture for raising and anti-slip purposes; the raising height is selectable, making it flexible and versatile, with complete overall functions and strong practicality.
