In order to achieve the purpose, the utility model is realized by the following technical scheme: the utility model provides a difficult wearing and tearing's fluting nut, its structure includes nut body, groove piece, nut body middle part is equipped with the internal thread hole, the groove piece is equipped with a plurality ofly to the nut body upper end is located to the equidistance interval, nut body upper end is equipped with the assembly groove corresponding with the groove piece, the groove piece lower extreme is equipped with the assembly piece of joining in marriage corresponding assembly groove, the assembly groove lower extreme is equipped with the constant head tank that passes through terminal surface under the nut body, the constant head tank internal rotation is equipped with the fixed column, the fixed column top is equipped with the screw rod, screw rod and assembly piece adopt threaded connection, the fixed column lower extreme is equipped with the instrument and rotates the groove.

Furthermore, the assembling block is tightly attached to the assembling groove, and the cross section of the assembling block is of a rectangular structure.

Further, the diameter of the positioning groove is larger than that of the assembling groove.

Furthermore, the inner sides of the groove blocks are provided with thread structures corresponding to the internal thread holes, and the inner thread holes of the groove blocks are surrounded into a ring.

Furthermore, the groove block is made of hard alloy materials.

The utility model has the beneficial effects that: if be equipped with the hole of installation limit structure on the screw rod, earlier with the slotted nut screw in, see which groove piece can interfere with the hole, then unscrew slotted nut, unscrew the corresponding fixed column of groove piece that can interfere through the instrument, the restriction to the assembly piece is relieved to the fixed column, this groove piece can break away from the assembly groove together with the assembly piece, screw in screw rod at last just can not produce with the limit structure of follow-up needs installation and interfere the conflict, the groove piece of assembled, can carry out the dismouting according to the particular case, the convenience of assembly work has been improved, and the groove piece adopts the carbide material to make, difficult wearing and tearing.

Drawings

Other features, objects and advantages of the utility model will become more apparent upon reading of the detailed description of non-limiting embodiments with reference to the following drawings:

FIG. 1 is a schematic structural view of a hard-to-wear slotted nut of the present invention;

fig. 2 is a schematic cross-sectional view taken along line a-a of fig. 1.

Detailed Description

In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the utility model easy to understand, the utility model is further described with the specific embodiments.

Referring to fig. 1 and 2, the present invention provides a grooved nut with less wear: the nut comprises a nut body 1 and groove blocks 2, wherein the middle part of the nut body 1 is provided with an internal thread hole 3, the groove blocks 2 are provided with a plurality of groove blocks 2, the groove blocks are arranged at the upper end of the nut body 1 at equal intervals, the upper end of the nut body 1 is provided with an assembly groove 4 corresponding to the groove blocks 2, the lower end of the groove blocks 2 is provided with an assembly block 5 matched with the corresponding assembly groove 4, the lower end of the assembly groove 4 is provided with a positioning groove 6 penetrating out of the lower end surface of the nut body 1, a fixing column 7 is rotationally arranged in the positioning groove 6, the top of the fixing column 7 is provided with a screw rod 8, the screw rod 8 is in threaded connection with the assembly block 5, the lower end of the fixing column 7 is provided with a tool rotating groove 9, the assembly block 5 is tightly attached to the assembly groove 4, the cross section of the assembly block 5 is in a rectangular structure, the diameter of the positioning groove 6 is larger than that of the assembly groove 4, the inner sides of the groove blocks 2 are provided with thread structures corresponding to the internal thread hole 3, a plurality of groove blocks 2 enclose a ring by taking the internal threaded hole 3 as the center, and the groove blocks 2 are made of hard alloy materials.

For example, if the screw is provided with a hole for installing a limiting structure, the slotted nut is screwed in firstly, which slot block 2 can interfere with the hole, then the slotted nut is screwed out, the fixing column 7 corresponding to the slot block 2 which can interfere is screwed out through a tool, the fixing column 7 removes the limitation on the assembly block 5, the slot block 2 can be separated from the assembly groove 4 together with the assembly block 5, and finally the screw is screwed in, so that interference conflict with the subsequent limiting structure which needs to be installed can not be generated, the assembled slot block 2 can be disassembled and assembled according to special conditions, the convenience of assembly work is improved, and the slot block 2 is made of hard alloy materials and is not easy to wear.
