Description

Anti-drop's stable form nut

Technical Field

The utility model relates to a machine part technical field especially relates to an anti-drop's stable form nut.

Background

Generally, bolts and nuts are widely used in various fields such as assembling electric vehicles, automobile parts, electronic parts, furniture, and structures in construction sites, and are mainly used for connecting two or more different objects that can be detached.

The coupling force of the bolt and the nut is easily weakened when the bolt and the nut are subjected to external shock and vibration, and the nut coupled to the bolt screw shaft is easily loosened when the nut is subjected to strong external shock and shock during use, so that the coupling strength is reduced, the coupled components are loosened, and greater loss is caused.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the defects existing in the prior art and providing an anti-drop stable nut.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides an anti-drop's stable form nut, includes screw thread piece and U type seat, the lower surface mounting of screw thread piece has the annular slab, the annular slab is located the inside of U type seat, a plurality of teeth are installed to the outside edge equidistant of annular slab, the middle part of annular slab and the lower surface middle part of screw thread piece are equipped with the mounting groove jointly, the internally mounted of mounting groove has the second spring, the carriage release lever, two has all been run through to the both sides of U type seat the arc rack with the tooth meshing is all installed to the one end that the carriage release lever is relative, the second spring of contradicting with the arc rack has all been cup jointed in the outside of carriage release lever.

Preferably, the thread block, the annular plate and the teeth are integrally formed.

Preferably, the lower surface of the U-shaped seat is provided with a plurality of anti-skid protrusions.

Preferably, the thread block is of a regular hexagonal structure.

Preferably, the moving rod has a quadrangular structure.

The utility model provides an anti-drop's stable form nut, beneficial effect lies in: the utility model discloses the second spring that is equipped with can produce elasticity to the screw thread piece to make screw thread on the screw thread piece stronger with the screw thread contact force on the bolt, prevent to produce between bolt and the screw thread piece not hard up, the U type seat that is equipped with and the object that is connected fully contact, screw up the screw thread piece after, arc rack and tooth meshing under the effect of first spring, thereby prevent that the annular plate from taking place to rotate, just also can prevent that the screw thread piece from taking place not hard up, compared with the prior art, convenient to use, novel structure can effectually prevent to take place to become flexible between screw thread piece and the bolt, thereby improves the connection stability of the object of being connected, prevents that the object of being connected from receiving the damage, and the practicality is strong, is worth using widely.

Drawings

Fig. 1 is a schematic front view of an anti-falling stable nut of the present invention;

fig. 2 is a schematic top view of an anti-falling stable nut according to the present invention;

fig. 3 is a schematic view of a bottom view of the anti-falling stable nut of the present invention.

In the figure: the spring comprises a thread block 1, a first spring 2, an annular plate 3, a second spring 4, a mounting groove 5, an arc-shaped rack 6, an anti-skid protrusion 7, a moving rod 8, a U-shaped seat 9 and teeth 10.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-3, an anti-drop's stable form nut, includes screw block 1 and U type seat 9, is the integrated into one piece structure between screw block 1, annular plate 3 and tooth 10, improves joint strength, reinforcing stability in use.

The lower surface of U type seat 9 is equipped with a plurality of non-slip raised 7, and non-slip raised 7 is in order to prevent that U type seat 9 from taking place to rotate, reinforcing anti-drop effect.

The thread block 1 is of a regular hexagon structure, so that the use effect is enhanced for convenience.

The lower surface mounting of screw block 1 has annular plate 3, annular plate 3 is located the inside of U type seat 9, a plurality of teeth 10 are installed to the outside edge equidistant of annular plate 3, the middle part of annular plate 3 and the lower surface middle part of screw block 1 are equipped with mounting groove 5 jointly, the internally mounted of mounting groove 5 has second spring 4, the carriage release lever 8 has all been run through to the both sides of U type seat 9, carriage release lever 8 is quadrilateral, in order to prevent that arc rack 6 from taking place to rotate relative U type seat 9, and convenience in use is improved.

The arc-shaped racks 6 meshed with the teeth 10 are installed at the opposite ends of the two moving rods 8, and the second springs 4 abutted against the arc-shaped racks 6 are sleeved on the outer sides of the moving rods 8.

The working principle is as follows: during the use, pass the second spring 4 with the bolt, U type seat 9, annular plate 3 and screw block 1, screw block 1 is connected with the bolt screw thread, the second spring 4 that is equipped with can produce elasticity to screw block 1, thereby make the screw thread on the screw block 1 stronger with the screw thread contact force on the bolt, it is not hard up to prevent to produce between bolt and the screw block 1, screw block 1 drives annular plate 3 extrusion U type seat 9, the U type seat 9 that is equipped with and the object that is connected fully contact, screw up screw block 1 back, arc rack 6 and tooth 10 meshing under the effect of first spring 2, thereby prevent that annular plate 3 from taking place to rotate, just can prevent that screw block 1 from taking place to become flexible.
