Description

Technical Field

[0001] This application relates to the technical field of connectors, and more specifically, to a screw connection structure for electronic products. Background Art

[0002] A screw is a tool that uses the physical and mathematical principles of the inclined plane circular rotation and friction of an object to gradually tighten the machine parts. It is widely used in the field of electronic products, such as bolts and screws, which connect two parts of an electronic product together and play a fastening role.

[0003] However, some screws used for connecting electronic products on the current market have certain limitations. Specifically, after long-term use, they often become slightly loose, which may cause accidental damage to the electronic products and need to be further improved. Utility Model Content

[0004] In order to solve the above problems, this application provides a screw connection structure for electronic products.

[0005] The screw connection structure for electronic products provided by this application adopts the following technical solutions:

[0006] A screw connection structure for electronic products includes a screw head and a screw rod. A slotted cross recess is provided at the top of the screw head, and a threaded hole penetrating vertically is provided in the middle of the screw head. A cylindrical block is threadedly connected in the threaded hole. A cross recess is provided at the top end of the cylindrical block, and a frustum-shaped extrusion head is provided at the bottom end of the cylindrical block. A receiving groove extending downward is provided at the top end of the screw rod, and a set of long strip-shaped reserved openings are provided on the outer side of the screw rod. The reserved openings are communicated with the receiving groove.

[0007] Further, the receiving groove is divided into three sections: an upper groove body, a middle groove body, and a lower groove body. The inner diameter of the upper groove body is equal to the diameter of the cylindrical block. The middle groove body is matched with the extrusion head. The inner diameter of the lower groove body is equal to the bottom diameter of the extrusion head.

[0008] Further, one of the slotted cross recess and the cross recess coincides.

[0009] Further, the spacing between two adjacent reserved openings is equal.

[0010] In summary, this application includes at least the following beneficial technical effects: By using a cross screwdriver to tighten the cylindrical block, the cylindrical block and the extrusion head are moved downward as a whole. During this process, the extrusion head gradually presses on the inner wall of the receiving groove, making the screw rod in a state of expanding outward, so that the connection between the screw rod and the electronic product is tighter, reducing the possibility of the screw becoming loose.

[0014] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application; obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0015] In the description of the present application, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "inner", "outer", "top / bottom end", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation of the present application. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0016] In the description of the present application, it should be noted that unless otherwise clearly defined and limited, the terms "installed", "provided with", "sheathed / connected", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0017] The following is a further detailed description of the present application in conjunction with the attached Figure 1-2 This application will be further described in detail.

[0018] The embodiments of the present application disclose a screw connection structure for an electronic product. Please refer to Figure 1, including a screw head 1 and a screw rod 2. It can be understood that the screw head 1 and the screw rod 2 are integrally formed. It should be noted that a slotted screwdriver slot 11 is provided at the top of the screw head 1, and a threaded hole 12 that penetrates vertically is provided in the middle of the screw head 1. A cylindrical block 3 is threadedly connected in the threaded hole 12. A cross slot 31 is provided at the top end of the cylindrical block 3. By inserting a matching cross screwdriver into the cross slot 31, the cylindrical block 3 can be screwed to adjust the vertical position of the cylindrical block 3. It can be understood that when the cylindrical block 3 is in the initial position, one of the slots of the slotted screwdriver slot 11 coincides with the cross slot 31, so as to use a slotted screwdriver to screw the screw head 1.

[0019] Please refer to Figure 2 , it should be noted that a frustum-shaped extrusion head 32 is provided at the bottom end of the cylindrical block 3. The extrusion head 32 is wider at the top and narrower at the bottom, and the extrusion head 32 is integrally formed with the cylindrical block 3. A receiving groove 21 extending downward is provided at the top end of the screw rod 2 for receiving the cylindrical block 3 and the extrusion head 32. A set of long strip-shaped reserved openings 22 are provided on the outer side of the screw rod 2. The reserved openings 22 communicate with the receiving groove 21, and the length of the reserved openings 22 is equal to the depth of the receiving groove 21. The spacing between two adjacent reserved openings 22 is equal. Further, it should be noted that the receiving groove 21 is divided into three sections: an upper groove body, a middle groove body, and a lower groove body. The inner diameter of the upper groove body is equal to the diameter of the cylindrical block 3. The middle groove body matches the extrusion head 32. The inner diameter of the lower groove body is equal to the bottom diameter of the extrusion head 32. When the cylindrical block 3 is tightened and moved downward, the cylindrical block 3 drives the extrusion head 32 to press the middle groove body of the receiving groove 21, so that the screw rod 2 is in a state of outward expansion, thereby making the connection between the screw rod 2 and the electronic product closer, so as to reduce the possibility of the screw loosening.

[0020] The implementation principle of the screw connection structure of an electronic product in an embodiment of the present application is as follows: When a screw needs to be used, first, use a slotted screwdriver to tighten the screw head 1 until the screw rod 2 completely enters the threaded hole of the electronic product. Then, use a cross screwdriver to tighten the cylindrical block 3, so that the cylindrical block 3 and the extrusion head 32 move downward as a whole. During this process, the extrusion head 32 gradually presses the inner wall of the receiving groove 21, so that the screw rod 2 is in a state of outward expansion, thereby making the connection between the screw rod 2 and the electronic product closer, so as to reduce the possibility of the screw loosening.

[0021] The above are all preferred embodiments of the present application. The protection scope of the present application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
