[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0034] Reference Figure 1-Figure 3 The utility model provides an embodiment: a riveted stud, comprising a threaded portion 1, a riveted portion 2 is fixedly connected to the top of the threaded portion 1, a mounting groove 3 is provided inside the riveted portion 2, a turntable 4 is rotatably connected inside the mounting groove 3, a cross groove is provided on the top of the turntable 4, a plurality of push blocks 5 are fixedly connected to the outer periphery of the turntable 4, the outer side of the push blocks 5 is designed as an arc, a plurality of storage grooves 6 are provided inside and outside the riveted portion 2, the interior of the storage groove 6 is communicated with the exterior of the riveted portion 2, and a sealing ring is installed on the side of the storage groove 6 close to the turntable 4.
[0035] Specifically, a backing groove is provided at the connection between the screw connection part 1 and the riveting part 2, so that the deformation part of the connecting member 11 can be connected to the riveting part 2, thereby making the installation between the connecting member 11 and the riveting part 2 more stable, and the installation groove 3 limits the internal turntable 4, so that the turntable 4 can rotate smoothly, and the turntable 4 supports and fixes the outer push block 5, so that the turntable 4 can drive the push block 5 to rotate, and the storage tank 6 can store lubricating oil inside, and a refueling port is provided at the top thereof, so that the lubricating oil inside the storage tank 6 can be replenished in time, and the sealing ring is fixedly connected to the outside of the turntable 4, so that when the push block 5 moves with the turntable 4, the lubricating oil inside the storage tank 6 will not leak.
[0036] Reference Figure 2-Figure 4 The outside of the push block 5 is slidably connected to the inside of the storage tank 6, a one-way valve 7 is installed inside the storage tank 6, a reinforcement component is installed inside the riveting part 2, the outside of the turntable 4 is slidably connected to a connecting piece 11, and a plurality of placement grooves 12 are opened inside the connecting piece 11. The plurality of placement grooves 12 are distributed in an annular shape and at equal intervals, and the plurality of placement grooves 12 are distributed horizontally.
[0037] Specifically, the storage groove 6 limits the push block 5 inside, so that the push block 5 can stably rotate with the storage groove 6. The one-way valve 7 allows the lubricating oil inside the storage groove 6 to be discharged when squeezed, and prevents the lubricating oil from flowing back when it is squeezed to the connection between the riveting part 2 and the connecting piece 11. The uniform distribution of the placement grooves 12 enables the connecting piece 11 to be more stably connected to the riveting part 2 when the placement grooves 12 are connected to the reinforcement assembly.
[0038] Reference Figure 3-Figure 5 The reinforcement component includes a plurality of fixing grooves 8, which are equidistantly distributed in a ring shape and horizontally distributed. The inner lower side of the fixing groove 8 is communicated with the inner upper side of the placement groove 12. The inner part of the fixing groove 8 is slidably connected with a support column 9. The bottom end of the support column 9 is connected with the inner mortise and tenon joint of the placement groove 12, and the top end of the support column 9 is fixedly connected with a pull ring 10.
[0039] Specifically, the fixing groove 8 limits the internal support column 9, so that the support column 9 can easily slide into the interior of the fixing groove 8, and the force on the support column 9 is more uniform, and the support column 9 can be inserted into the interior of the placement groove 12, thereby increasing the contact area between the riveting part 2 and the connecting piece 11, so that the riveting stud can be stably connected to the connecting piece 11, thereby increasing its service life.
[0040] Working principle: When the connector 11 needs to be installed on the outside of the riveting part 2 and the screw part 1, the riveting part 2 is connected to the bottom end of the mold, and then the connector 11 is slid from bottom to top, so that the connector 11 can slide upward along the outside of the screw part 1, so that the riveting part 2 can be pressed into the top of the connector 11, and at the same time, the support column 9 can be engaged with the placement groove 12 inside the connector 11, so that the connection between the connector 11 and the riveting part 2 is tighter, thereby increasing the connection area between the riveting stud and the connector 11, and thus making the connection between the riveting stud and the connector 11 tighter, so that the connection time is longer, thereby increasing the service life, thereby reducing the cost of use. Under the same principle, the pull ring 10 is pulled in the opposite direction, so that the support column 9 can be pulled out from the inside of the fixing groove 8 and the placement groove 12. At this time, by rotating the turntable 4 clockwise, the turntable 4 can drive the push block 5 to rotate clockwise, so that the push block 5 can squeeze the lubricating oil in the storage tank 6 into between the connecting piece 11 and the riveting part 2 through the one-way valve 7. At this time, the turntable 4 continues to be rotated, so that the turntable 4 can drive the riveting part 2 to shake slightly through the push block 5, thereby greatly reducing the friction between the connecting piece 11 and the riveting stud, so that the riveting part 2 can gradually detach from the inside of the connecting piece 11, and then the riveting stud can be conveniently pulled out from the inside of the connecting piece 11, thereby making the disassembly efficiency higher.
