Technical Field
The utility model relates to a be used for working of plastics medium and high strength nut belongs to high strength nut technical field.
Background
In the conventional connection field, because the strength and rigidity of the plastic part are low as a whole, if the plastic part is required to be connected with other parts, the following three ways are available:
the first mode is a direct tapping mode, the internal thread is low in strength, the applied torque is easy to slip and lose efficacy during assembly, and the strength requirement cannot be met.
The second is directly connected by a bolt and nut gasket mode, the connection mode not only needs a larger connection space, but also has a simple process but a complex installation process, and the connection part is easy to deform locally to cause the deformation of the plastic part and further pretension failure and other risks.
The third is to adopt embedded type, namely press the round nut into the plastic part through the action of the press, the installation mode has extremely high requirement on the size precision of the opening, and when assembling, the performance of the rotating torque is not very good, and when applying large torque, the round nut can rotate along with the bolt.
SUMMERY OF THE UTILITY MODEL
In view of the above-mentioned problems in the background art, a high strength nut for use in a plastic part is provided.
The utility model discloses the technical problem that will solve takes following technical scheme to realize:
a high-strength nut used in plastic parts comprises a nut body, wherein the nut body comprises a first flange supporting surface, a fixing block and a second flange supporting surface, the specification of the second flange bearing surface is larger than that of the first flange bearing surface, the head end and the tail end of the fixing block are respectively fixed with the first flange bearing surface and the second flange bearing surface, a first cavity is arranged in the middle of the inner part of the fixed block, a first cavity is also arranged in the middle of the first flange bearing surface and the second flange bearing surface, and the head and the tail of the first cavity on the fixed block are respectively communicated with the first cavity on the first flange bearing surface and the first cavity on the second flange bearing surface to form a second cavity, the inner side wall of the second cavity is provided with threads, and the first flange supporting surface is provided with a plurality of anti-skidding teeth for increasing friction at equal intervals.
As a preferred example, the first flange bearing surface, the fixing block and the second flange bearing surface are integrally formed.
As a preferred example, the fixed block shape is one of a hexagonal prism, a hepta-prism, or an octa-prism.
As a preferred example, the threading internal diameter dimension in the second cavity is M5-M8.
As a preferable example, the nut body is made of low carbon steel and/or stainless steel.
The utility model has the advantages that: the utility model discloses in moulding plastics the working of plastics with the nut body, make antiskid tooth supporting surface and big flange supporting surface expose the working of plastics respectively and flush with it, guaranteed the connection quality, satisfy the requirement of high strength and big rotation moment of torsion, can not influence the intensity of original material simultaneously to the installation is simple and convenient, sparingly connect part quantity.

Fig. 1 is a schematic structural view of the present invention;
FIG. 2 is a schematic structural view in another direction of the present invention;
fig. 3 is a schematic structural view of a connecting member to which the nut body of the present invention can be applied.
In the figure: the anti-skidding structure comprises a first flange supporting surface 1, a fixing block 2, a second flange supporting surface 3, threads 4, anti-skidding teeth 5, a plastic piece 6, a threaded hole 7 and an anti-skidding through groove 8.
Detailed Description
In order to make the technical means, the creation features, the achievement purposes and the functions of the present invention easy to understand and understand, the present invention is further explained by combining the following specific drawings.
As shown in fig. 1-3, a high-strength nut for plastic parts comprises a nut body, the nut body comprises a first flange supporting surface 1, a fixed block 2 and a second flange supporting surface 3, the specification of the second flange bearing surface 3 is larger than that of the first flange bearing surface 1, the head end and the tail end of the fixed block 2 are respectively fixed with the first flange bearing surface 1 and the second flange bearing surface 3, a first cavity is arranged at the middle position inside the fixed block 2, a first cavity is also arranged at the middle position between the first flange bearing surface 1 and the second flange bearing surface 3, and the head and the tail of the first cavity on the fixing block 2 are respectively communicated with the first cavity on the first flange bearing surface 1 and the first cavity on the second flange bearing surface 3 to form a second cavity, the inner side wall of the second cavity is provided with threads 4, and the first flange bearing surface 1 is provided with a plurality of anti-skid teeth 5 at equal intervals for increasing friction.
The first flange bearing surface 1, the fixing block 2 and the second flange bearing surface 3 are integrally formed.
The fixed block 2 is in the shape of one of a hexagonal prism, a hepta-prism or an octagonal prism.
The threads 4 in the second cavity have a tapped inner diameter dimension of M5-M8.
The nut body is made of low-carbon steel and/or stainless steel.
As shown in fig. 3, the anti-slip device is a plastic part 6, a threaded hole 7 is formed in the plastic part 6, a plurality of anti-slip through grooves 8 matched with the anti-slip teeth 5 are formed in one side wall of the plastic part 6, and the plurality of anti-slip through grooves 8 are communicated with the threaded hole 7.
