[0030] The following will be combined with the drawings of the utility model specification 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 of 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.

[0031] Reference Figure 1-Figure 3The utility model provides an embodiment: a ring groove rivet, including a riveted body 1, a connecting column 2 is fixedly connected to the top of the riveted body 1, and a nail cap 3 is fixedly connected to the top of the connecting column 2. The diameter of the connecting column 2 is adapted to the diameter of the installation hole on the installation object, and by inserting the rivet into the installation object, the bottom of the nail cap 3 can be abutted against the surface of the installation object. A nail core 4 is fixedly connected to the bottom of the riveted body 1, and the rivet can be conveniently installed and fixed by the nail core 4 in conjunction with a tightening tool. An anti-slip ring 6 is provided on the outer periphery of the riveted body 1, and a locking sleeve 7 is fixedly connected to the top of the anti-slip ring 6. Through the cooperation of the anti-slip ring 6 and the nail cap 3, the fastened object and the installation object can be riveted and fixed. The inner wall of the locking sleeve 7 is fixedly connected with a plurality of locking rings 8 in sequence from top to bottom, and the outer periphery of the riveted body 1 is provided with a plurality of locking grooves 9 in sequence from top to bottom. Through the engagement of the locking grooves 9 and the locking rings 8, after the locking sleeve 7 is installed on the outer periphery of the riveted body 1, it is ensured that the locking grooves 9 and the locking rings 8 can be engaged and riveted, thereby completing the connection between the fastened object and the installed object.

[0032] Reference Figure 1-Figure 2 A plurality of stop blocks 10 are fixedly connected to the bottom edge of the connecting column 2, and a plurality of stop grooves 11 are provided on the top of the locking sleeve 7. The cooperation between the stop blocks 10 and the stop grooves 11 can effectively inhibit the movement between the riveted body 1 and the locking sleeve 7, and ensure that there is no relative rotation between the riveted body 1 and the locking sleeve 7. A stop assembly is installed on the inner side of the locking sleeve 7. A plurality of circumferentially distributed limiting grooves 13 are provided on the outer periphery of the riveted body 1. The cooperation between the stop assembly and the limiting grooves 13 can effectively ensure the stability of the connection between the various components of the rivet, and also ensure the convenience of rivet installation. The outer side of the stop block 10 is inserted into the inside of the stop groove 11, and the cooperation between the stop block 10 and the stop groove 11 can further ensure the stability between the riveted body 1 and the locking sleeve 7.

[0033] Reference Figure 1 and Figure 3 The bottom of the nail cap 3 is fixedly connected with an upper sealing ring 15, and the top of the anti-slip ring 6 is fixedly connected with a lower sealing ring 14. The lower sealing ring 14 contacts the surface of the fastened object, and the upper sealing ring 15 contacts the surface of the installed object, thereby ensuring the sealing of the gap at the connection. The outer side of the riveted body 1 is penetrated by the anti-slip ring 6 and the locking sleeve 7, so as to facilitate the subsequent assembly of the locking sleeve 7 on the outer side of the riveted body 1 for riveting. The multiple stop blocks 10 are distributed in a circle, and the multiple stop grooves 11 are distributed in a circle. The stop blocks 10 and the stop grooves 11 correspond to each other one by one. The cooperation between the stop blocks 10 and the stop grooves 11 can limit the locking sleeve 7, ensuring that there is no relative movement between the locking sleeve 7 and the riveted body 1.

[0034] Reference Figure 2-Figure 3A breaking groove 5 is provided between the riveted body 1 and the nail core 4. Through the breaking groove 5, the nail core 4 protruding from the inside of the fastened object can be quickly broken after the annular groove rivet is riveted and installed. The stop assembly includes a plurality of limit strips 12, and the plurality of limit strips 12 are fixedly connected to the inner wall of the locking sleeve 7, and the plurality of limit strips 12 are distributed in a circumference. Through the cooperation between the limit strips 12 and the limit grooves 13, the locking sleeve 7 and the riveted body 1 are stopped to avoid relative movement. At the same time, the limit strips 12 and the limit grooves 13 can ensure that the stop groove 11 and the stop block 10 can be accurately plugged together. The outer side of the limit strip 12 is slidably connected to the inside of the limit groove 13, and the limit strip 12 is limited by the limit groove 13 to ensure that the locking sleeve 7 does not rotate after riveting.

[0035] Working principle: When riveting, insert the ring groove rivet from the mounting hole of the object and pass it out from the mounting hole on the fastened object at the same time, then insert the locking sleeve 7 and the anti-slip ring 6 from the bottom end of the nail core 4, and put the locking sleeve 7 and the anti-slip ring 6 on the outside of the rivet. Then, push the anti-slip ring 6 upward so that the locking sleeve 7 enters the outer periphery of the riveted body 1. At this time, adjust the position of the locking sleeve 7 to ensure that the limit strip 12 can be smoothly inserted into the limit groove 13. Then, install the tightening tool from the outer periphery of the riveted body 1, and twist the tool to push the anti-slip ring 6 upward, so that the anti-slip ring 6 moves up and enters the outer periphery of the riveted body 1. At this time, the locking ring 8 will move with the movement of the locking sleeve 7 and be inserted into the locking groove 9 on the outer periphery of the riveted body 1 in sequence. Until the anti-slip ring 6 moves to directly clamp the fastening object and the installation object, at this time, the anti-slip ring 6 rivets the fastening object and the installation object by cooperating with the nail cap 3, and at the same time, the locking ring 8 on the inner side of the locking sleeve 7 will be correspondingly clamped in the locking groove 9 to ensure that the locking sleeve 7 will not be separated from the outer periphery of the riveted body 1, and then the fastening object and the installation object are riveted and fixed. At the same time, when the riveting is completed, the cooperation of the limiting groove 13 and the limiting strip 12 ensures that the stop groove 11 at the top of the locking sleeve 7 will be plugged and matched with the stop block 10 at the bottom of the connecting column 2 when the rivet is riveted. Then, the riveted body 1 and the locking sleeve 7 are limited by the cooperation of the stop block 10 and the stopping groove 11, the limiting groove 13 and the limiting strip 12, so as to avoid the horizontal rotation of the locking sleeve 7 and the riveted body 1 when subjected to force, so that the rivet riveting is more stable.
