Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

As shown in fig. 1 to 3, a pressure riveting nut assembly includes a main body 1, a support member 2 and a screw 3, and is characterized in that a first limiting portion 12 is disposed at an end of the main body 1, a first channel 13 penetrating through the main body 1 is disposed inside the main body 1, a first support portion 21 and a second support portion 22 are disposed at upper and lower ends of the support member 2, a second channel 23 penetrating through the middle of the support member 2 and used for the main body 1 to penetrate through, and the screw 3 penetrates through the first channel 13 and is in threaded connection with the main body 1, wherein the first limiting portion 12 and the first support portion 21 form a first limiting region 4, and a head of the screw 3 and the second support portion 22 form a second limiting region 5.

The utility model discloses in, control two distances that need be between the fixed spare part through first supporting part 21 and the second supporting part 22 on support piece 2, two spare parts set up respectively in first spacing district 4 and the spacing district 5 of second, through the tight mode of first spacing portion 12 and the tight mode of first supporting part 21 clamp, the head of screw 3 is fixed with the tight mode of second supporting part 22 clamp.

Screw 3 and 1 threaded connection of main part, cooperation support piece 2 fixes two spare parts at the both ends of main part 1 simultaneously, and is fixed effectual, and the fixed spacing distance precision between two spare parts is high.

The utility model discloses have better fixed effect, it is fixed convenient and dismantle also convenient.

The utility model discloses well screw 3, fixing bolt 6 all include the head and the body of rod, are equipped with the external screw thread on the body of rod.

Specifically, the inner wall of the first channel 13 has an internal thread 131 that fits the screw. For screwing in of the screw 3.

Specifically, the fixing device further comprises a fixing bolt 6, a threaded hole 31 is formed in the end portion of the rod body of the screw 3, the fixing bolt 6 is inserted from the other end of the through hole and is in threaded connection with the threaded hole 31, and the head of the fixing bolt 6 abuts against the first limiting portion 12. After the screw 3 is screwed in and fixed, the fixing bolt 6 is inserted from the other end of the main body 1 and the fixing bolt 6 is screwed into the screw hole 31, so that the screw 3 is prevented from loosening.

In particular, the length of the shank of the screw 3 is less than the length of the first channel 13. The body of rod of screw 3 is avoided wearing out from main part 1, influences the installation of other parts.

Alternatively, the support member 2 has an expansion section 24 in the middle, and the expansion section 24 can expand and shorten the distance between the first support portion 21 and the second support portion 22 when an external force is applied.
