[0045] The utility model provides a riveting spring screw used in a riveting process. The utility model does not limit the type of the installed structure, but the structure of the riveting spring screw is particularly suitable for a chassis shell and a luggage case.

[0046] In general, the riveted spring screw proposed in the utility model mainly includes a riveted bolt 1, a riveted sleeve 2, a riveted head 3, and a spring 4. Figure 1 , which shows the arrangement relationship of the riveting bolt 1, the riveting sleeve 2, the riveting head 3, and the spring 4.

[0047] In order to achieve the purpose of one-handed operation and rapid positioning of riveting, the problem that screws are usually used to achieve riveted connection for structural connections on aircraft and automobiles in the background technology is solved, and the separate combination of the rivet sleeve and the screw requires two-handed operation to provide better control and stability during installation. However, in a narrow or compact chassis environment, two-handed operation becomes difficult to perform in a limited space. One hand holds the screwdriver and the other hand fixes the screw or the chassis, which increases the complexity of the operation and thus reduces the installation efficiency. For this reason, in the technical solution provided in this embodiment, a structure in which the rivet bolt 1 and the rivet head 3 are integrally arranged, in cooperation with the rivet sleeve 2 and the spring 4, one-handed alignment with the accessory installation is achieved, and the effect of rotating the screw into the accessory is improved, which facilitates positioning while effectively improving the installation efficiency.

[0048] Specifically, Figure 1 As shown, the rivet bolt 1, the rivet sleeve 2 and the rivet head 3 are all coaxially arranged, the rivet head 3 is fixedly installed on the rivet bolt 1, the rivet bolt 1 and the rivet head 3 are sleeved on the rivet sleeve 2, and under the action of the spring 4, they form an initial state of mutual abutment. During operation, the end of the rivet sleeve 2 away from the bolt head 11 of the rivet bolt 1 is aligned and riveted to the counterpart. After alignment, the rivet bolt 1 is driven to rotate by a screwdriver or an electric tool, so that the rivet head 3 and the rivet bolt 1 rotate and move along the outer wall of the rivet sleeve 2 in the direction of approaching or away from the counterpart.

[0049] like Figure 3 As shown, the rivet bolt 1 provided in this embodiment includes a bolt head 11 and a screw rod 12 integrally arranged along the axial direction, and a connecting end 13 is integrally arranged on one side of the bolt head 11 close to the screw rod 12, wherein the outer diameter of the connecting end 13 is smaller than the outer diameter of the bolt head 11, and in addition, in order to realize the structure of an integral fixed connection between the rivet bolt 1 and the rivet head 3, a rivet bolt knurl 14 is circumferentially arranged on the connecting end 13.

[0050] On this basis, the matching rivet head 3 is provided with an installation groove 31 for installing the bolt head 11 at its top, and the inner diameter of the installation groove 31 is slightly larger than the outer diameter of the bolt head 11. After installation, the top of the rivet head 3 and the top of the bolt head 11 are flushly arranged, so as to achieve the consistency of the overall structure and prevent the protruding bolt head 11 from damaging other parts. In addition, a hexagonal connection groove 15 is provided at one end of the bolt head 11 away from the screw rod 12, and the polygonal structure is also convenient for connection with a screwdriver, which has an effective anti-slip effect.

[0051] Next, a second through hole 32 for passing the screw rod 12 is opened at the bottom of the installation groove 31. In addition, in order to achieve a tight connection between the rivet head 3 and the rivet bolt 1, the connecting end 13 with vertical knurling and rivet bolt knurling 14 is inserted into the second through hole 32 to form a tight connection structure; after installation, the screw rod 12 of the rivet bolt 1 extends out of the rivet head 3, and the bottom of the rivet head 3 is sleeved on the outer surface of the rivet sleeve 2, using the rivet sleeve 2 as a guide structure.

[0052] Since the riveting spring screw is manually operated, a vertical anti-skid knurling 33 is provided on the outer circumference of the riveting head 3, which can increase the friction and provide a gripping area for manually rotating the screw. At the same time, it can also play an anti-skid role, ensuring that the riveting head 3 is not easy to slide or fall off during use, thereby greatly improving work efficiency.

[0053] It is necessary to explain in detail the structure of the riveting sleeve 2. The outer portion is used to guide the riveting head 3, and the inner portion is used to pass the riveting bolt 1 and install the spring 4. The riveting sleeve 2 is provided with a limit end 21, a riveting sleeve body 22 and a riveting end 23 in sequence along the axial direction when viewed from the outside, wherein the outer diameters of the limit end 21, the riveting sleeve body 22 and the riveting end 23 gradually decrease;

[0054] In order to match the rivet head 3 installed on the top, the outer diameter of the limiting end 21 is larger than the outer diameter of the rivet sleeve body 22, but smaller than the bottom inner diameter of the rivet head 3. In addition, the outer bottom of the rivet sleeve 2 is provided with a first chamfer 24, which can effectively avoid the contact area between the rivet head 3 and the rivet sleeve 2, thereby preventing the occurrence of sliding damage;

[0055] Furthermore, a lower abutting end 25 is provided at one end of the riveted end 23 located inside the riveting sleeve body 22. Since the inner diameter of the lower abutting end 25 is smaller than the outer diameter of the spring 4, the spring 4 can be conveniently installed and confined in the riveting sleeve 2, thereby playing an elastic role on the riveted bolt 1 and the riveting sleeve 2. In addition, the lower abutting end 25 is arranged in an inclined structure, gradually rising in the direction away from the central axis. The spring 4 can play a buffering role in the accessory, protecting the components or equipment sheet metal inside the accessory from damage. The spiral spring can also be used to tighten the screw in the mounting hole to prevent it from loosening and maintain the tightening force.

[0056] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed by the present invention shall still be covered by the claims of the present invention.
