Description

Technical Field

[0001] This utility model relates to the field of self-tapping screw technology, and in particular to a self-tapping screw structure. Background Art

[0002] Self-tapping screws, as a common fastener, are widely used in various assembly and structural connections, especially in the connection of materials such as metals and plastics. Their unique design allows them to form a tight bond with the materials being connected without the need for pre-drilled holes, making them widely used in industries such as construction, automotive, and electronics. However, existing self-tapping screws have some problems in practical use, including difficulty in installation, unreliable fixing, and insufficient mating precision.

[0003] Traditional self-tapping screws often require multiple tools for installation, and slippage or misalignment can occur during the connection process. This not only increases the complexity of manual operation but can also lead to loosening and instability of the structural connection. Similarly, due to the lack of effective positioning and reinforcement mechanisms during connection, the bolts may not be properly secured, thus affecting the reliability of the overall structure. Although some improved self-tapping screw designs have emerged in the market, they still suffer from inconvenient operation, poor fixing effect, and narrow applicability. Therefore, we provide a self-tapping screw structure. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a self-tapping bolt structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a self-tapping screw structure, comprising: a rotating mechanism, the rotating mechanism including a rotating head, a connecting rod provided on one side of the rotating head, an insertion hole provided on the connecting rod, an insertion block provided in the insertion hole, a collar provided on the outer surface of the insertion block, a buckle provided on both sides of the collar, and an installation mechanism provided at the end of the connecting rod away from the rotating head;

[0006] The mounting mechanism includes a screw rod, one end of which is provided with a threaded rod, and silicone dots are provided on the screw rod. The end of the screw rod away from the threaded rod is provided with a cross-shaped opening.

[0007] In a preferred embodiment, one end of the docking rod is fixedly connected to one side of the rotating head, and an insertion hole is provided on the docking rod.

[0008] In a preferred embodiment, the outer surface of the interpenetrating block is inserted into the interpenetrating hole, and the outer surface of the collar is nested in the interpenetrating block.

[0009] In a preferred embodiment, one end of the buckle is fixedly connected to the collar, and the threaded end of the screw rod is fixed to the end of the connecting rod away from the rotating head by means of threaded rotation.

[0010] In a preferred embodiment, the silicone dots are fused onto the teeth of the screw rod.

[0011] In a preferred embodiment, a cross-shaped opening is provided at the end of the screw rod away from the threaded rod.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] This invention involves nesting the inner surface of a collar within a connecting rod, then using an insert block to mate it with the connecting rod. The operator can then use a screw rod with a threaded end to fix the screw to the connecting rod via threaded rotation. Alternatively, the operator can use a screwdriver aligned with a rotating head to apply pressure to the cross-shaped opening at the desired fixing point, and then use the screw rod to fix the screw via threaded rotation.

[0026] Example 1

[0027] like Figure 1-4As shown, this utility model provides a technical solution: a self-tapping screw structure, including: a rotating mechanism 1, the rotating mechanism 1 including a rotating head 11, a connecting rod 12 provided on one side of the rotating head 11, an insertion hole 13 provided on the connecting rod 12, an insertion block 14 provided in the insertion hole 13, a collar 15 provided on the outer surface of the insertion block 14, a buckle 16 provided on both sides of the collar 15, and an installation mechanism 2 provided at the end of the connecting rod 12 away from the rotating head 11;

[0028] The mounting mechanism 2 includes a screw rod 21, one end of which is provided with a threaded rod 22, a silicone dot 23 is provided on the screw rod 21, and a cross opening 24 is provided at the end of the screw rod 21 away from the threaded rod 22.

[0029] One end of the connecting rod 12 is fixedly connected to one side of the rotating head 11. An insertion hole 13 is cut into the connecting rod 12. The outer surface of the insertion block 14 is inserted into the insertion hole 13. The outer surface of the collar 15 is nested in the insertion block 14. One end of the buckle 16 is fixedly connected to the collar 15. One end of the screw rod 21 with the threaded rod 22 is fixed to the end of the connecting rod 12 away from the rotating head 11 by the threaded rotation. The silicone dots 23 are fused onto the teeth on the screw rod 21. A cross opening 24 is cut into the end of the screw rod 21 away from the threaded rod 22.

[0030] In this embodiment, when the operator uses this bolt for fixing, the inner surface of the collar 15 can be nested in the connecting rod 12, and then the insert block 14 can be inserted and connected to the connecting rod 12. Then, the operator can use the end of the screw rod 21 with the threaded rod 22 to fix it to the connecting rod 12 by threaded rotation. Then, the operator can use a screwdriver to align with the rotating head 11, and then install the rotating head 11 to make the cross opening 24 open at the place to be fixed by applying pressure. Then, the screw rod 21 can be fixed by threaded rotation. The collar 15 and the buckle 16 on the outer surface of the connecting rod 12 can further reinforce the installation position, thereby further improving its practicality in actual use.

[0031] Working principle:

[0032] like Figure 1-4 As shown, the inner surface of the collar 15 is nested on the outer surface of the mating rod 12 to ensure that the two fit tightly and remain stable. Next, the insert block 14 is used to insert it into the reserved slot of the mating rod 12. In this way, the component position is initially fixed to prevent the component from shifting during installation.

[0033] Subsequently, workers can use one end of the screw rod 21 to securely fix it into the base hole of the connecting rod 12 by rotating it through its threaded body 22. This process requires ensuring the tightness of the threaded connection to enhance the load-bearing capacity and stability of the entire device.

[0034] The next step involves a more precise fixing process. The operator uses a screwdriver to operate on the rotating head 11 at the top of the screw rod. By rotating the rotating head 11, sufficient pressure is applied to the tip of the cross-shaped opening 24, thus creating a hole to be fixed. This design allows the device to achieve precise positioning during the fixing process and also meets installation requirements in different scenarios through the drilling operation.

[0035] Once the opening is complete, the operator can continue to rotate the screw rod 21 to further secure it to the target position via threaded rotation. Simultaneously, to ensure the overall installation's firmness and stability, the outer surface of the connecting rod 12 is designed with a collar 15 and a locking device 16. These two components provide secondary reinforcement to the installation position after the device is installed. The collar 15 provides additional support by covering the outer structure, while the locking device 16 prevents the risk of loosening through a clamping mechanism.

[0036] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary and is not intended to imply that the scope of the present invention (including the claims) is limited to these examples; within the framework of the present invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of different aspects of the present invention as described above, which are not provided in the details for the sake of brevity.

[0037] This utility model is intended to cover all such substitutions, modifications, and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
