Description

Technical Field

[0001] This utility model relates to the field of screw technology, specifically to a screw that is easy to store. Background Technology

[0002] In the field of mechanical assembly and parts management, hexagonal screws are commonly used fasteners, and their storage efficiency directly affects production and maintenance costs.

[0003] In existing technologies, traditional hexagonal screws have significant storage problems: their individual structure makes them easy to scatter due to rolling and collision when stored in batches, especially small screws which are often lost due to disorderly stacking; when screws of different sizes are mixed, external storage boxes are needed for partitioned management, but the screws themselves lack a self-positioning structure, so they still need to be searched one by one during the retrieval process, which is time-consuming and laborious; in addition, disorderly stacking of screws can easily cause thread wear or stripping of the head, affecting the accuracy of subsequent assembly. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In view of the shortcomings of the existing technology, this utility model provides a screw that is easy to store.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a screw that is easy to store, including a screw cap, a screw rod fixedly disposed at the lower end of the screw cap, a positioning groove provided at the top of the screw cap, the diameter of the positioning groove being the same as the diameter of the screw rod, and anti-slip texture provided on the inner wall of the positioning groove.

[0008] To make the stacking of multiple screws more stable, the present invention is improved by fixing a locking block at the center of the positioning groove, and providing a locking groove at the bottom of the screw rod that cooperates with the locking block.

[0009] To make the fit between the card block and the card slot more stable, the improvement of this utility model is that the card block fits tightly against the inner wall of the card slot, and the card block has a rectangular structure.

[0010] To facilitate the fitting of the card block and the card slot, the improvement of this utility model is that the corner of the top of the card block is provided with an arc surface.

[0011] Furthermore, an improvement of this utility model is that the screw cap, the locking block, and the screw rod are an integrated structure.

[0012] (III) Beneficial Effects

[0013] Compared with the prior art, this utility model provides a screw that is easy to store, and has the following beneficial effects:

[0014] The positioning groove and screw rod interlock, combined with the locking structure of the clip and slot, allow the screws to be stacked in a chain, preventing them from rolling and scattering when stored separately, and keeping them neatly arranged even if the storage box is tilted.

[0015] In chain-style storage mode, screw specifications are automatically distinguished by stacking layers, eliminating the need to search through partitioned storage boxes and shortening retrieval time. The tight fit between rectangular blocks and slots prevents screws from rotating or becoming misaligned during stacking, further facilitating quick and easy access. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-3 A screw that is easy to store includes a screw cap 1, a screw rod 2 fixedly installed at the lower end of the screw cap 1, and a positioning groove 4 provided at the top of the screw cap 1. The diameter of the positioning groove 4 is the same as the diameter of the screw rod 2, and the inner wall of the positioning groove 4 is provided with anti-slip texture.

[0022] A locking block 5 is fixedly installed at the center of the positioning groove 4, and a locking groove 3 that cooperates with the locking block 5 is provided at the bottom end of the screw rod 2. The locking block 5 is in close contact with the inner wall of the locking groove 3, and the locking block 5 has a rectangular structure.

[0023] When using it, the operator first takes one screw and aligns the positioning groove 4 on the top of its screw cap 1 with the bottom end of the screw shaft 2 of the other screw.

[0024] Because the inner wall of the positioning groove 4 is provided with anti-slip texture, when the screw rod 2 is inserted into the positioning groove 4, the anti-slip texture will increase the friction between the two and prevent loosening.

[0025] The top corner of the card block 5 is provided with an arc surface 6.

[0026] At this time, the rectangular block 5 in the center of the positioning groove 4 will be embedded in the slot 3 at the bottom of the screw rod 2. The block 5 fits tightly against the inner wall of the slot 3, and the arc surface 6 (arc degree of 30-45 degrees) at the top of the block 5 can guide the block 5 to be inserted smoothly, avoiding structural damage caused by hard collision.

[0027] Multiple screws are connected sequentially in the above manner to keep the plane of the screw cap 1 consistent, forming a chain-like stacked structure.

[0028] This structure allows the items to be laid flat and neatly inside the storage box, preventing them from rolling and scattering.

[0029] When the screw needs to be removed, simply apply a pulling force to the screw cap 1 to pull the screw rod 2 out of the positioning groove 4. The mating structure of the locking block 5 and the locking groove 3 will not cause wear to the threads.

[0030] The screw cap 1, the locking block 5, and the screw rod 2 are an integrated structure.

[0031] Since the screw cap 1, the locking block 5, and the screw rod 2 are integrated into one piece, the parts will not fall off during the entire storage process, ensuring operational stability.

[0032] The anti-slip texture enhances the stability of the insertion and avoids hard friction between the screw rod 2 and the inner wall of the positioning groove 4; the arc surface 6 of the corner of the locking block 5 reduces wear during insertion.

[0033] Positioning slot 4:

[0034] Turning:

[0035] The top of the nut 1 is circumferentially cut using a CNC lathe. A cylindrical groove with the same diameter as the screw rod 2 is first machined out. The groove depth is precisely controlled according to the design requirements (usually 1 / 2 to 2 / 3 of the diameter of the screw rod 2) to ensure that the screw rod 2 can be inserted into the positioning groove 4 without loosening.

[0036] The anti-slip texture on the inner wall is achieved through a knurling process: a knurling tool is used to roll out a mesh or straight texture on the inner wall of the groove, with a texture depth of 0.1-0.2mm, which increases the friction after the screw rod 2 is inserted and prevents slippage.

[0037] Applicable scenarios:

[0038] Suitable for screws made of metal materials such as carbon steel and stainless steel, they can be processed by automated lathe production lines during mass production, with dimensional accuracy controlled within ±0.05mm.

[0039] Card slot 3:

[0040] Milling process:

[0041] Using a CNC milling machine or machining center, a rectangular slot 3 is milled on the bottom end face of the screw rod 2. The dimensions of the slot 3 match those of the block 5 (width error ±0.02mm, depth error ±0.05mm).

[0042] During processing, the axis of screw rod 2 is used as a reference to ensure that the center of the slot 3 and the center of the block 5 are aligned to avoid misalignment during assembly.
