Description

Technical Field

[0001] This utility model relates to the field of hardware fastener technology, specifically to a bolt assembly with an expansion hole. Background Technology

[0002] Bolts, as commonly used fasteners in the mechanical field, are widely used in the assembly of various equipment and structures. They reliably secure components by mating with threaded holes on fixed surfaces. In practical applications, the demand for diverse bolt functions is increasing.

[0003] There is a type of bolt in the prior art, see reference. Figure 1 As shown, it includes a screw 01 and a screw head 02. The screw head 02 is provided with a connecting rod 03 extending in the opposite direction. The connecting rod 03 can be used as a hanging rod or a screw, effectively expanding the application scenarios.

[0004] However, this type of bolt with a connecting rod has drawbacks in practical use. On the one hand, the connecting rod 03 and the screw head 02 are fixedly connected, and it cannot be disassembled when the function of the connecting rod 03 is not needed. This not only occupies space but may also cause damage to the component or affect the overall assembly aesthetics due to accidental contact. On the other hand, because the position of the connecting rod 03 is fixed, it is difficult to fine-tune its position according to actual needs in complex assembly environments, which limits the applicability of the bolt in special working conditions and reduces assembly flexibility and efficiency.

[0023] 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.

[0024] For reference as follows Figures 1-5 The present invention will be described as follows:

[0025] Example: A bolt assembly with an expansion hole includes a screw 01 and a screw head 02. Optimized structural design allows for flexible assembly, disassembly, and position adjustment of the connecting rod 03, effectively improving the bolt's applicability in mechanical assembly.

[0026] Screw 01 serves as a basic fastening component. Its outer surface is threaded for engaging with the threaded hole on the fixing surface to achieve initial fixation of the component and the target component.

[0027] The screw head 02 and the screw rod 01 are integrally formed. The left and right sides of the screw head 02 extend outward to form extensions 4, and the three together form an elongated rectangular structure. This structural design increases the contact area between the screw head and the fixing surface, providing a more uniform force distribution during tightening and enhancing connection stability.

[0028] The extension section 4 is the key carrier for realizing the extended function. The extension section 4 is provided with an adjustment groove 5 that runs through both sides of its thickness direction. The groove is arranged along the length direction of the extension section 4 and provides a guide track for the movement of the connecting rod 03.

[0029] The inner surface of the extension 4 is provided with a groove 6 corresponding to the adjustment groove 5. The width of the groove 6 is greater than the width of the adjustment groove 5, forming a stepped internal space. This special design allows the moving block 7 to slide within the groove 6 after the adjustment groove 5 is connected, while restricting the displacement of the moving block 7 in the direction perpendicular to the adjustment groove 5, ensuring its stable operation. The adjustment groove 5 is connected to the groove 6.

[0030] A movable block 7 is slidably connected inside the adjustment groove 5. The movable block 7 is the core component for connection and adjustment. Its external dimensions are adapted to the groove 6, and it can slide freely inside the groove 6.

[0031] The movable block 7 is provided with a threaded hole 9 corresponding to the adjusting groove 5. The specifications of the threaded hole 9 are matched with the external thread of the connecting rod 03.

[0032] It also includes a connecting rod 03, which passes through the adjusting groove 5 and connects to the threaded hole 9.

[0033] When the connecting rod 03 is needed, it is passed through the adjusting groove 5 and screwed into the threaded hole 9 of the moving block 7. Since the moving block 7 can slide within the groove 6, it moves the connecting rod 03 along the adjusting groove 5, thus allowing the position of the connecting rod 03 to be adjusted within a certain range to adapt to different assembly requirements. When the connecting rod 03 is not needed, it can be removed from the threaded hole 9 of the moving block 7 by screwing it on, effectively solving the problem of the connecting rod being unable to be removed in traditional structures.

[0034] In actual use, after the screw 01 is screwed into the threaded hole of the fixing surface, the screw head 02 and the extension 4 are in close contact with the fixing surface. At this time, the moving block 7 is confined within the groove 6, located between the fixing surface and the extension 4, ensuring that the moving block 7 will not undergo accidental displacement under normal tightening conditions. Through the above structural design, this bolt assembly retains the tightening function of traditional bolts while innovatively realizing the flexible disassembly and position adjustment of the connecting rod, significantly improving the versatility and practicality of bolts in complex assembly scenarios.

[0035] Both the adjusting groove 5 and the recess 6 are elongated, and both are arranged along the length of the extension 4. This design provides a precise sliding track for the moving block 7.

[0036] The diameter of the connecting rod 03 is equal to the width of the adjusting groove 5, which ensures that the connecting rod 03 can slide freely while limiting its radial sway.

[0037] The movable block 7 is connected in the groove 6. The diameter of the movable block 7 is equal to the width of the groove 6, and the thickness of the movable block 7 is equal to the depth of the groove 6. The width of the groove 6 is greater than that of the adjusting groove 5, forming a stepped structure. Its width is equal to the diameter of the movable block 7, and its depth is consistent with the thickness of the movable block 7, so that the movable block 7 can move smoothly and remain stable within the groove 6.

[0038] The elongated groove structure limits the movement path of the moving block 7, ensuring that the connecting rod 03 can only be adjusted along the length of the extension 4.

[0039] The stepped design of the groove 6 prevents the moving block 7 from coming out of the adjustment groove 5, while the fit between the fixed surface and the extension 4 restricts the axial displacement of the moving block 7.

[0040] Through the precise fit between the groove and the components, extended functionality is achieved within a limited space while maintaining the overall compactness of the bolt assembly.

[0041] The outer surface of the screw head 02 is provided with a hexagonal operating groove 8, which provides an efficient way to install and remove components.

[0042] In practical applications, operators can insert a hex wrench into the operating slot 8 and apply torque to cause the screw head 02 to rotate the screw rod 01, thus achieving a threaded connection with the fixed surface. This design retains the tightening function of traditional bolts while enabling flexible adjustment and disassembly of the connecting rod 03 through an innovative structure, significantly improving the applicability of bolts in complex assembly environments.

[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
