DETAILED DESCRIPTION
[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0025] like Figure 1-Figure 6 As shown, this embodiment provides an embodiment of a round nut anti-loosening locking plate.
[0026] The nut 2 is provided with an anti-loosening locking plate, and the anti-loosening locking plate structure 3 includes a locking plate body 4 sleeved on the bolt 1, a plurality of breakable buckles 5 are installed on the outer ring of the locking plate body 4, and a limiting block 6 is fixedly installed on the inner ring of the locking plate body 4. The nut 2 is provided with a plurality of grooves 7 for cooperating with the breakable buckles 5, and the bolt 1 is provided with a limiting groove 8 adapted to the limiting block 6. Through the setting of the anti-loosening locking plate structure 3, it can be used normally even in some high-frequency vibration occasions. The locking plate body 4 is sleeved on the bolt 1 and the position of the limiting block 6 is adjusted to be vertical with the limiting groove 8, and then the locking plate body 4 is moved until the limiting block 6 and the limiting groove 8 are completely closed, and then the nut 2 is placed on the bolt 1 and the nut 2 is screwed until the position of the breakable buckle 5 corresponds to the groove 7. Finally, the plurality of breakable buckles 5 are pressed into the inside of the groove 7 to complete the locking of the nut 2, and it will not be loosened due to high-frequency vibration.
[0027] A plurality of mounting holes 9 are provided on the limit block 6, a spring 10 is fixedly installed inside the mounting hole 9, a clamping block 11 is fixedly installed at one end of the spring 10, a plurality of clamping holes 12 used in conjunction with the clamping block 11 are provided inside the limit groove 8, through the arrangement of the mounting holes 9, the spring 10, the clamping block 11 and the clamping holes 12, when the limit block 6 is inserted into the limit groove 8, the clamping block 11 is squeezed and contracted to the inside of the mounting hole 9, and when 19 moves to the position of the clamping hole 12, it is engaged with the limit block 6 under the elastic action of the spring 10, and this engaging structure can be used in different scenarios without the need to hold the lock plate body 4 by hand to twist the nut 2 when the lock plate body 4 is installed in an inverted manner, and can be suitable for use in different scenarios.
[0028] One end of the block 11 is configured to be arc-shaped. The arc-shaped configuration of the block 11 can reduce the friction force at one end of the block 11, so that the block 11 can slide easily in the limiting groove 8, thereby facilitating the installation of the locking plate body 4.
[0029] A rubber pad 13 is provided at the bottom of the lock plate body 4. The rubber pad 13 can increase the friction at the bottom of the lock plate body 4 to avoid excessive friction between the lock plate body 4 and other objects when the nut 2 is tightened, thereby shortening the life of the lock plate body 4.
[0030] A first magnet 14 is fixedly installed on one side of the bendable buckle 5, and a second magnet 15 connected to the nut 2 is fixedly installed inside the groove 7. Through the arrangement of the first magnet 14 and the second magnet 15, after a plurality of bendable buckles 5 are pressed into the groove 7, the first magnet 14 and the second magnet 15 are attracted to each other to further strengthen the closure of the nut 2 and the locking plate body 4.
[0031] The nut 2 is provided with a plurality of tooth grooves 16. The arrangement of the tooth grooves 16 can increase the friction force on the surface of the nut 2, so that the nut 2 is more labor-saving and convenient to screw.
[0032] The surfaces of the bolt 1, nut 2 and lock plate body 4 are all provided with electro-galvanizing. By providing the electro-galvanizing on the surfaces of the bolt 1, nut 2 and lock plate body 4, the anti-corrosion performance of the three can be enhanced. In addition, the electro-galvanizing has low cost and strong adhesion ability, and the zinc layer will not fall off even if there is a strong collision.
[0033] In this embodiment, if Figure 1-Figure 6 As shown, the working process of a round nut anti-loosening locking plate provided in this embodiment is as follows:
[0034] The locking piece body 4 is sleeved on the bolt 1 and the position of the limit block 6 is adjusted to be vertical with the limit groove 8. Then the locking piece body 4 is moved until the limit block 6 and the limit groove 8 are completely closed. Then the nut 2 is placed on the bolt 1 and the nut 2 is twisted until the position of the bendable buckle 5 corresponds to the position of the groove 7. Finally, multiple bendable buckles 5 are pressed into the inside of the groove 7 to complete the locking of the nut 2, and it will not loosen due to high-frequency vibration.
[0035] In summary, in this embodiment, according to a round nut anti-loosening lock plate of this embodiment, through the settings of the mounting hole 9, the spring 10, the clamping block 11 and the clamping hole 12, when the limit block 6 is inserted into the limit groove 8, the clamping block 11 is squeezed and contracted to the inside of the mounting hole 9, and when 19 moves to the position of the clamping hole 12, it is engaged with the limit block 6 under the elastic action of the spring 10. This engaging structure can be used in a case where the lock plate body 4 is inverted and installed without the need to hold the lock plate body 4 by hand to twist the nut 2, and can be suitable for use in different scenarios. By setting one end of the clamping block 11 to be arc-shaped, the friction force at one end of the clamping block 11 can be reduced, so that the clamping block 11 is easy to slide in the limit groove 8, which is convenient for the installation of the lock plate body 4, and the rubber pad 13 is used. The setting can increase the friction at the bottom of the lock plate body 4, and avoid excessive friction between the lock plate body 4 and other objects when the nut 2 is tightened, which leads to a shortened life of the lock plate body 4. Through the setting of the first magnet 14 and the second magnet 15, after the multiple breakable buckles 5 are pressed into the groove 7, the attraction between the first magnet 14 and the second magnet 15 can further strengthen the closure of the nut 2 and the lock plate body 4. Through the setting of the tooth groove 16, the friction on the surface of the nut 2 can be increased, so that the nut 2 is more labor-saving and convenient to twist. Through the setting of electrogalvanizing on the surface of the bolt 1, the nut 2 and the lock plate body 4, the anti-corrosion performance of the three can be enhanced, and the electrogalvanizing has low cost and strong adhesion, and the zinc layer will not fall off even if it is strongly impacted.
