Technical Field

[0001] The utility model relates to the field of blind rivets, in particular to a blind rivet for preventing deformation. Background Art

[0002] A blind rivet, also known as a blind rivet or a pull rivet, is a mechanical rivet used for single-sided riveting. A blind rivet is a specially designed rivet that allows the riveting operation to be completed from one side of the workpiece. A blind rivet usually consists of two parts: a rivet body (also called a tube cap) and a rivet core (also called a nail, a nail rod). The rivet body is the part that remains in the workpiece after riveting, while the rivet core is the part used to pull the rivet body to expand for riveting. It is suitable for riveting occasions where the surface needs to be smooth, such as furniture, electrical appliances, etc.

[0003] Regarding the existing technology, there are the following problems:

[0004] In the existing technology, the anti-deformation effect of the blind rivet is poor. The core part of the blind rivet may be unstable due to reasons such as materials and processes, resulting in a relatively high core-pulling rate. This means that in some application scenarios, the blind rivet may not provide sufficient fixing force, thus affecting the stability and safety of the overall structure. And if the core rod is deformed, the overall blind rivet cannot be used in cooperation with the installation tool, so it cannot be used normally. Content of the Utility Model

[0009] The outer wall of the connecting rod is movably connected to a core rod, a reinforcing rod is fixedly connected to the inner wall of the core rod, and a connecting block is fixedly connected to the outer wall of the connecting rod, which can make the blind rivet have a good anti-deformation effect. The reinforcing plate can ensure that the end cap is not deformed and cannot be inserted into the installation hole. The reinforcing rod can prevent the core rod from being deformed and bent and unable to cooperate with the nail gun normally, so as to ensure that the overall shape of the blind rivet will not change, avoid being unable to provide reinforcement force due to deformation and unable to be used normally, and meet the usage requirements of people.

[0010] Preferably, the reinforcing plate is an annular reinforcing plate, and the annular reinforcing plate can provide reinforcement for the outer wall of the end cap, so as to prevent deformation of a part of the outer wall of the end cap and failure to maintain a circular structure, thus affecting entry into the interior of the mounting hole.

[0011] Preferably, an extrusion groove is formed at one end of the end cap, and the shape and size of the extrusion groove are both matched with those of the end head, which makes it more convenient and rapid for the end head to enter the interior of one end of the end cap.

[0012] Preferably, a movable groove is provided on the inner wall of the end cap, and the end cap is movably connected to the core rod through the movable groove, which makes it more convenient for the core rod to perform lateral displacement inside the end cap.

[0013] Preferably, a connecting groove is formed on the inner wall of the core rod, and the core rod is movably connected to the connecting rod through the connecting groove and the connecting block. The connecting block cooperates with the connecting groove to enable the core rod to be separated from the connecting rod along with the pulling force for cutting operation.

[0014] (III) Beneficial effects

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0022] Embodiment 1

[0023] A preferred embodiment of the anti-deformation blind rivet provided by the present invention is as Figures 1 to 3 shown: An anti-deformation blind rivet includes an end cap 1. A reinforcing plate 2 is fixedly connected to the front surface of the end cap 1. An inner rod 3 is movably connected to the inner wall of the end cap 1. One side of the inner rod 3 is fixedly connected to a head 4, and one side of the inner rod 3 is fixedly connected to a connecting rod 5.

[0024] The outer wall of the connecting rod 5 is movably connected to a core rod 6. A reinforcing rod 7 is fixedly connected to the inner wall of the core rod 6. A connecting block 8 is fixedly connected to the outer wall of the connecting rod 5, which can make the blind rivet have a good anti-deformation effect. The reinforcing plate 2 can ensure that the end cap 1 is prevented from deforming and unable to be inserted into the installation hole. The reinforcing rod 7 can prevent the core rod 6 from deforming and bending and being unable to cooperate with the nail gun normally. In this way, it ensures that the overall shape of the blind rivet will not change, and avoids being unable to provide a reinforcement force due to deformation and being unable to be used normally, meeting the usage requirements of people.

[0025] In this embodiment, the reinforcing plate 2 is an annular reinforcing plate. The annular reinforcing plate 2 can provide reinforcement for the outer wall of the end cap 1, thereby preventing part of the outer wall of the end cap 1 from deforming and being unable to maintain a circular structure, thus affecting entry into the interior of the installation hole.

[0026] Embodiment 2

[0027] On the basis of Embodiment 1, a preferred embodiment of the anti-deformation blind rivet provided by the present invention is as Figures 1 to 3 shown: An extrusion groove is provided at one end of the end cap 1, and the shape and size of the extrusion groove are both mutually matched with the shape and size of the head 4. The extrusion groove makes it more convenient and faster for the head 4 to enter the interior of one end of the end cap 1.

[0028] In this embodiment, a movable groove is provided on the inner wall of the end cap 1, and the end cap 1 is movably connected to the core rod 6 through the movable groove. The movable groove makes it more convenient for the core rod 6 to perform a lateral displacement inside the end cap 1.

[0029] Furthermore, a connecting groove 9 is provided on the inner wall of the core rod 6, and the core rod 6 is movably connected to the connecting rod 5 through the connecting groove 9 and the connecting block 8. The connecting block 8 cooperates with the connecting groove 9 to enable the core rod 6 to break away from the connecting rod 5 along with the pulling force for a truncation operation.

[0030] During use, insert the integral blind rivet into the installation hole, then insert the core rod 6 into the interior of the rivet gun, and then use the rivet gun to clamp and pull the core rod 6. The core rod 6 pulls the connecting rod 5 and the inner rod 3, and the inner rod 3 pulls the end 4 to squeeze and enter the interior of the end cap 1. After the reinforcement is stable, the connecting block 8 will gradually disengage from the connecting rod 5 through the connecting groove 9 in sequence to cut off the core rod 6, thus completing the work.

[0031] In summary, the anti-deformation blind rivet can achieve the purpose of good anti-deformation effect. The reinforcing plate 2 can ensure that the end cap 1 is prevented from deforming and unable to be inserted into the interior of the installation hole, and the reinforcing rod 7 can prevent the core rod 6 from deforming and bending and being unable to cooperate with the rivet gun normally, thereby ensuring that the overall shape of the blind rivet does not change, avoiding the inability to provide reinforcement force due to abnormal use caused by deformation, and meeting the usage requirements of people.
