Description

Technical Field

[0001] This utility model relates to the field of fastener technology, and in particular to a screw that is easy to rotate. Background Technology

[0002] Screws, as a common threaded component, are widely used in mechanical structures. For example, screws in some bicycles are used to lock the seat height. When adjusting the seat height, tools such as wrenches or screwdrivers are used to loosen the screws, and after adjusting the height, the screws are tightened again. This kind of screw adjustment requires the use of external tools. When exercising outdoors, it is impossible to adjust the seat height without the appropriate tools. While some wing screws are convenient to turn manually, their wing-shaped heads are easy to turn when subjected to external force, which can cause the screws to loosen. Utility Model Content

[0003] In order to overcome the above-mentioned shortcomings of existing screws, this utility model proposes a screw in which the screw body can be rotated by a hidden rotating rod without the need for external tools, thus improving the convenience of use. At the same time, the head is not easily loosened by external force.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A screw that is easy to rotate includes a screw body and a rotating rod. The screw body includes a screw shank and a head. The head has a substantially circular cross-section. A mounting groove is coaxially provided within the screw body. One end of the mounting groove extends to the end face of the head, forming a non-circular insertion port. The head has grooves on both sides of the insertion port. The rotating rod includes a rotating rod body and an elastic element. The rotating rod body is adapted to the mounting groove and inserted into it. The elastic element is fixedly connected to one end of the rotating rod body near the insertion port. The elastic element engages with the groove, and at least part of the elastic element protrudes outside the groove. The other end of the rotating rod body can be embedded in the groove to rotate the screw body.

[0006] With the above settings, firstly, the screw body can be rotated using the rotating rod without additional tools, making it convenient to rotate the screw body outdoors and improving ease of use; secondly, the rotating rod can be hidden inside the screw body, and the head of the screw body is rounded, making it less prone to loosening after being subjected to external force.

[0007] Furthermore, the socket is hexagonal.

[0008] With the above setup, if the rotating rod is lost, a hex wrench can be inserted into the socket to rotate the screw body in place of the rotating rod.

[0009] Furthermore, a side groove is vertically provided at the bottom of the groove, and the side groove can be embedded in the rotating rod body.

[0010] With the above configuration, the rotating rod body can be embedded in the side groove when rotating, thereby preventing the end of the rotating rod body from separating from the head when rotating.

[0011] Furthermore, the elastic element is a rod-shaped structure made of elastic material. One end of the elastic element is located in the groove and is fixedly connected to the side of the end of the rotating rod body. The other end of the elastic element obliquely penetrates the side groove and extends to the outside of the side groove.

[0012] Furthermore, the main body of the rotating rod is made of alloy material.

[0013] Furthermore, the outer end of the rotating rod body is flush with the insertion port. Attached Figure Description

[0018] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0019] like Figures 1 to 4 A convenient rotating screw includes a screw body 3 and a rotating rod 4. The screw body 3 includes a screw shank 31 and a head 32. The head 32 has a basically circular cross-section. A mounting groove 5 is coaxially provided inside the screw body 3. One end of the mounting groove 5 extends through to the end face of the head 32, forming a non-circular insertion port 6. The head 32 has grooves 7 on the left and right sides of the insertion port 6. The rotating rod 4 includes a rotating rod body 41 and an elastic element 42. The rotating rod body 41 is adapted to the mounting groove 5 and inserted into the mounting groove 5. The elastic element 42 is fixedly connected to one end of the rotating rod body 41 near the insertion port 6. The elastic element 42 engages with the groove 7. The elastic element 42 at least partially protrudes from the groove 7. The other end of the rotating rod body 41 can be embedded in the groove 7 to rotate the screw body 3.

[0020] With the above settings, firstly, the screw body 3 can be rotated using the rotating rod 4 without the need for additional tools, making it convenient to rotate the screw body 3 outdoors and improving ease of use; secondly, the rotating rod 4 can be hidden inside the screw body 3, and the head 32 of the screw body 3 is rounded, making it less prone to loosening after being subjected to external force.

[0021] Usage: Move the elastic element 42 with your finger to pull the rotating rod 4 out of the mounting groove 5. The end of the rotating rod body 41 away from the elastic element 42 passes through the groove 7 and the socket 6 from the side of the head 32, similar to a lever. Push the other end of the rotating rod body 41 by hand to rotate the screw body 3, thus realizing the disassembly and assembly of the screw body 3. After pulling the rotating rod body 41 out of the groove 7, insert the rotating rod body 41 back into the mounting groove 5 through the socket 6. The outer end of the rotating rod body 41 is flush with the socket 6. The elastic element 42 is re-engaged with the groove 7 to prevent the rotating rod 4 from falling out of the mounting groove 5. At this time, the rotating rod 4 is basically hidden in the mounting groove 5. The head 32 is basically cylindrical with a rounded outer surface. It will not rotate under external force, thus achieving an anti-loosening effect.

[0022] As one implementation method, the socket 6 is a regular hexagon.

[0023] With the above setup, when the rotating rod 4 is lost, a hex wrench can be inserted into the socket 6 to rotate the screw body 3 in place of the rotating rod 4.

[0024] The rotating rod body 41 of this application has a two-section structure. The first section of the rotating rod body 41, which is closer to the socket 6, has a larger outer diameter and a cross-section that is a regular hexagonal structure that fits the socket 6. The second section has a smaller outer diameter and extends into the screw part 31 through the mounting groove 5. It has a circular cross-section. The rotating rod body 41 of this application is made of alloy material and has high strength. The ratio of the outer diameter of the second section of the rotating rod body 41 to the outer diameter of the screw part 31 is less than 1 / 2 to ensure the strength of the screw part 31.

[0025] As one implementation, a side groove 8 is vertically provided at the bottom of the groove 7, and the side groove 8 can be embedded in the rotating rod body 41.

[0026] With the above configuration, the rotating rod body 41 can be embedded in the side groove 8 when rotating, thereby preventing the end of the rotating rod body 41 from separating from the head 32 when rotating.

[0027] In one implementation, the elastic element 42 is a rod-shaped structure made of elastic material. One end of the elastic element 42 is located in the groove 7 and is fixedly connected to the side of the end of the rotating rod body 41. The other end of the elastic element 42 obliquely penetrates the side groove 8 and extends to the outside of the side groove 8.

[0028] In principle, the elastic element 42 is a rod-shaped structure made of elastic material such as metal or plastic. The height of the elastic element 42 protruding from the head 32 is greater than 2mm, which makes it easy to flick with a finger. When the finger flicks the outer end of the elastic element 42, the outer end of the elastic element 42 deforms into the groove 7, and the elastic element 42 can be flicked upward to pull the rotating rod 4 out of the mounting groove 5.

[0029] As one implementation method, the main body of the rotating rod is made of alloy material.

[0030] As one implementation method, the outer end of the rotating rod body is flush with the insertion port.

[0031] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
