Description

Technical Field

[0001] This utility model relates to the field of rivets, and in particular to a rivet with an anti-loosening structure. Background Technology

[0002] A rivet is a nail-shaped object used to connect two parts (or components) with through holes and caps at one end. In riveting, the parts are joined by their own deformation or interference fit. There are many types of rivets, and they come in various forms. Commonly used types include R-type rivets, fan rivets, blind rivets (push-button rivets), tree rivets, round-head rivets, flat-head rivets, semi-hollow rivets, solid rivets, and countersunk rivets.

[0003] For example, a patent entitled "A Rivet with an Anti-Loss Structure" (patent application number: CN202223286060.3) discloses a rivet with an anti-losing structure. After the rivet body is installed, the fixing part drives the top of the insert to rotate outward around the axis of rotation under the action of the compression spring through the setting of the pushing mechanism. This causes the pointed locking block to move to the outside of the rivet body and engage with the outer wall of the rivet body. Although this enhances the connection strength with the wall, when it is necessary to remove the rivet, the pushing mechanism cannot drive the pointed locking block to retract. The resisting action of the pointed locking block makes it more difficult to remove the rivet.

[0004] Therefore, it is necessary to propose a rivet with an anti-detachment structure to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a rivet with an anti-loosening structure to solve the problem that although the connection strength with the wall is enhanced, when it is necessary to remove the rivet, the pushing mechanism cannot drive the pointed locking block to retract, and the resisting action of the pointed locking block makes the removal of the rivet more difficult.

[0006] To achieve the above objectives, the present invention provides the following technical solution: including a rivet body, wherein a first screw hole is provided at the top of the rivet body, and a threaded groove is provided inside the first screw hole, the threaded groove extending into the rivet body;

[0007] The threaded groove is threaded with a pushing mechanism, and the outside of the rivet body is provided with a groove. An abutment block is rotatably connected in the groove. After the pushing mechanism moves downward, it pushes out the abutment block and extends it out of the groove.

[0008] Preferably, the pushing mechanism includes a screw, the bottom end of which is set as a tapered end, the groove and the threaded groove are internally connected, one end of the abutment block extends into the threaded groove, and a bevel is provided on the extended end, the inclination angle of which corresponds to the outer side of the tapered end.

[0009] Preferably, the bottom end of the abutment block is provided with a rotating shaft, which is rotatably connected to the inside of the groove, and a torsion spring is provided on the rotating shaft.

[0010] Preferably, the top end of the screw has a second screw hole, and the inner side of the threaded groove and the outer side of the screw are threaded together.

[0011] Preferably, at least two grooves are provided, and the heights of the two grooves correspond.

[0012] Preferably, the bottom end of the rivet body is configured as a pointed tip.

[0013] Preferably, the area of ​​the second screw opening is smaller than the area of ​​the first screw opening, and the height of the first screw opening is higher than the height of the second screw opening.

[0014] Preferably, the side of the abutting block away from the rivet body is flush with the outer side of the rivet body.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. After the rivet body is screwed into the wall, use a screwdriver to align the second screw head and rotate the second screw head to rotate the screw rod. As the screw rod rotates and descends, it can press the beveled edge of the abutment block through the tapered end, causing the abutment block to extend out of the groove and abut against the inside of the wall, preventing the rivet body from moving after installation. At the same time, by rotating the screw rod in the opposite direction, the abutment block loses its abutting force. Through the elastic force of the torsion spring, the abutment block can automatically spring back into the groove, making it easy to remove the rivet body later.

[0017] 2. The area of ​​the second screw hole is smaller than that of the first screw hole, and the height of the first screw hole is higher than that of the second screw hole. This allows the screwdriver to make precise contact with both the second and first screw holes without interfering with each other. Attached Figure Description

[0022] This utility model provides, for example Figure 1 - Figure 2 The rivet shown is an anti-loosening structure, including a rivet body 1, a first screw hole 2 at the top of the rivet body 1, and a pointed bottom. The rivet body 1 can be screwed into a wall or object by the cooperation of the first screw 2 and a screwdriver.

[0023] The first screw opening 2 has a threaded groove 3 inside, which extends into the rivet body 1. The threaded groove 3 not only penetrates the first screw opening 2, but also extends into the interior of the rivet body 1, providing sufficient operating space for the pushing mechanism.

[0024] The threaded groove 3 is connected to a pushing mechanism. The rivet body 1 has a groove 5 on the outside. A contact block 6 is rotatably connected in the groove 5. After the pushing mechanism moves downward, the contact block 6 is pushed out of the groove 5.

[0025] The driving mechanism includes a screw 10, the bottom end of which is a tapered end 7. The groove 5 and the threaded groove 3 are internally connected. One end of the contact block 6 extends into the threaded groove 3, and a bevel 9 is provided on the extended end. The inclination angle of the bevel 9 corresponds to the outer side of the tapered end 7. A second screw hole 4 is provided at the top of the screw 10, and the inner side of the threaded groove 3 and the outer side of the screw 10 are threaded together. When the screw 10 is rotated, the screw 10 can move up and down within the threaded groove 3.

[0026] The bottom end of the abutment block 6 is provided with a rotating shaft 8, which is rotatably connected to the inside of the groove 5, and a torsion spring is provided on the rotating shaft 8, which can make the abutment block 6 rotate.

[0027] After the rivet body 1 is screwed into the wall, the screw 10 is rotated by aligning the screw with the second screw hole 4 and rotating the second screw hole 4. As the screw 10 rotates and descends, it can press the inclined edge 9 of the abutment block 6 through the tapered end 7, causing the abutment block 6 to extend out of the groove 5 and abut against the inside of the wall, thus preventing the rivet body 1 from moving after installation. At the same time, by rotating the screw 10 in the opposite direction, the abutment block 6 loses its abutting force. Through the elastic force of the torsion spring, the abutment block 6 can automatically spring back into the groove 5, making it easy to remove the rivet body 1 later.

[0028] At least two grooves 5 are provided, and the heights of the two grooves 5 correspond. The corresponding heights of the grooves 5 form a symmetrical structure. This design is not only aesthetically pleasing, but more importantly, it ensures that the contact block 6 is subjected to uniform force and stable movement in all directions.

[0029] The area of ​​the second screw opening 4 is smaller than that of the first screw opening 2, and the height of the first screw opening 2 is higher than that of the second screw opening 4. This allows the screwdriver to make precise contact with both the second screw opening 4 and the first screw opening 2 when in use, thus avoiding mutual interference.

[0030] The side of the abutment block 6 away from the rivet body 1 is flush with the outer side of the rivet body 1, so that the outer surface of the rivet can remain flat when the abutment block 6 is retracted. This makes the overall appearance of the rivet neater when the abutment function is not used, and also reduces potential interference to surrounding parts.

[0031] Working principle: First, insert the rivet body 1 into the parts to be connected. When the abutment function is required, rotate the screw 10 with a tool, and the screw 10 moves downward within the threaded groove 3. As the screw 10 moves downward, its tapered end 7 gradually contacts the inclined edge 9 of the abutment block 6, which extends into the threaded groove 3. Because the inclination angle of the inclined edge 9 matches the inclination angle of the outer side of the tapered end 7, the tapered end 7 applies an outward pushing force to the inclined edge 9, causing the abutment block 6 to rotate around the pivot 8 and extend out of the groove 5.

[0032] When the abutment block 6 is fully extended, it can form a stable abutment relationship with the connected parts, thereby enhancing the connection strength and stability of the rivet. When it is necessary to retract the abutment block 6, simply rotate the screw 10 in the opposite direction to move it upward. The thrust of the tapered end 7 on the inclined side 9 disappears, and the abutment block 6 is retracted into the groove 5 under the action of the elastic restoring force of the torsion spring, returning to its initial state.

[0033] 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 principles of the present utility model should be included within the protection scope of the present utility model.
