Problems solved by technology

[0002] The existing principle of vertical splicing through plates is generally to embed nuts into the plates first and then penetrate through the screws from the outside to splice the two plates vertically. The screw heads must be cylindrical because they need to be screwed into the plates. The loose performance is not good, and the screw head is generally narrow as a whole, and the horizontal force capacity of the vertically spliced ​​panels is poor

Embodiment 1

[0034] to combine figure 1The shown corrosion-resistant fixing screw for improving the three-dimensional splicing strength of plate parts includes a screw 1, and the material of the screw 1 is austenitic stainless steel, and the whole body is carburized. Moreover, the screw 1 includes a first shaft segment 11 and a second shaft segment 12, the second shaft segment 12 is arranged at one end of the first shaft segment 11, the diameter of the second shaft segment 12 is smaller than that of the first shaft segment 11, The end of the first shaft section 11 away from the second shaft section 12 is provided with a screwdriver recess 13, the end of the first shaft section 11 near the screwdriver recess 13 is provided with a first thread 14, and the second shaft section 12 is provided with a second Two threads 15, and the first thread 14 and the second thread 15 have opposite screw directions. At the same time, it also includes a base body 2 , the base body 2 is a hexagonal nut, and a...

Embodiment 2

[0038] combine figure 2 The shown corrosion-resistant fixing screw for improving the three-dimensional splicing strength of board parts, on the basis of Embodiment 1, an extension plate 22 is provided at the bottom of the seat body 2, and a group of nails 23 are provided on the extension board 22 . ,

[0039] When the connecting plate is a wooden board, the nail portion of the extension board 22 is nailed into the wooden board while the base body 2 is buried in the wooden board, so as to improve the reliability of splicing.

Embodiment 3

[0041] combine Figure 3-6 The method for using a corrosion-resistant fixing screw to improve the three-dimensional splicing strength of the panels shown in Example 1 is shown, wherein the panel to be spliced ​​includes a seat panel 6 and a riser 7, and the riser 7 needs to be spliced ​​vertically on the seat On the plane of plate 6, the steps involved are as follows:

[0042] S1: Slot holes are provided on the seat plate 6 and the vertical plate 7, wherein a counterbore 61 and a through hole 62 are provided on the plane of the seat plate 6, the counterbore 61 is adapted to the contour of the seat body 2, and the through hole 62 is provided in In the projected area of ​​counterbore 61; Wherein, offer shaft hole 71 on the side of riser 7, and set up bushing groove 72 on the plane of riser 7, described shaft hole 71 is adapted to first shaft segment 11, described The bushing groove 72 is adapted to the bushing 3, and the shaft hole 71 communicates with the bushing groove 72;

Abstract

The invention discloses a corrosion-resistant fixing screw capable of improving the three-dimensional splicing strength of the plates and the using method. When the screw is matched with the shaft sleeve, a bolt with a head is integrally formed; and the shaft sleeve is a bolt head, and the base body is a nut; during use, the screw and the shaft sleeve need to be embedded into the side faces of a splice plate, and the first threaded ends are exposed; meanwhile, the base body is embedded into the counter bores of the other splice plate; the screwdrivers penetrate through the first threaded holes to enter the screwdriver concave parts, and the screws are screwed; and after the first threads and the first threaded holes are screwed tightly, the two plates are vertically spliced and fixed; and the spring upwards ejects the screw shaft out of the plate through the shaft sleeve, and the anti-loosening effect is achieved after installation is completed. Different from the general mode that the screw is directly screwed in from the outside and matched with the internal nut, the screw is screwed out from the inside to be matched with the external base body; and the base body is embedded in the surface of the plate through the counter bore, the base body cannot rotate in the circumferential direction, and the reinforcing and anti-loosening effects are achieved.

Description

technical field [0001] The invention relates to the technical field of manufacturing high-performance mechanical base parts, in particular to a corrosion-resistant fixing screw for improving the three-dimensional splicing strength of board parts and a use method thereof. Background technique [0002] The existing principle of vertical splicing through plates is generally to embed nuts into the plates first and then penetrate through the screws from the outside to splice the two plates vertically. The screw heads must be cylindrical because they need to be screwed into the plates. The loose performance is not good, and the screw heads are generally narrow as a whole, and the horizontal force bearing capacity of the vertically spliced ​​panels is poor. Contents of the invention [0003] In order to overcome the deficiencies of the above-mentioned prior art, the present invention provides a corrosion-resistant fixing screw that improves the three-dimensional splicing strength...
