Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Example (b): a high-strength stainless steel fastener is shown in figures 1 and 2 and comprises an upper cap body 1 and a rod body 2, wherein the upper cap body 1 and the rod body 2 are separately formed, so that the requirements of independent forming processing and processing technologies of all parts are met, and the reliable connection strength of the stainless steel fastener after final combination is improved.
As shown in fig. 2 and 3, a pair of fan-shaped slots 3 are formed in the side wall of the cap body 1, the pair of fan-shaped slots 3 are oppositely arranged in the middle of the cap body 1, a vertical rod slot 4 is further formed in the side wall of the cap body 1, the vertical rod slot 4 is communicated with one side of the fan-shaped slot 3 on one side, a falling slot 5 is further formed in the middle of the cap body 1, the falling slot 5 is perpendicular to the vertical rod slot 4, a limiting insert 6 which is in inserting fit with the falling slot 5 is arranged at the top end of the rod body 2, when an operator assembles the rod body 2 to the cap body 1, the limiting insert 6 and the rod body 2 are firstly inserted along the vertical rod slot 4, when the rod body 2 is in contact with the slot wall of the vertical rod slot 4, the operator rotates the rod body 2 to enable the limiting insert 6 to horizontally rotate in the fan-shaped slots 3, and when the limiting insert 6 is horizontally rotated by 90 degrees, the alignment of the limiting insert 6 in the vertical direction can be realized, meanwhile, the falling position of the limiting insertion block 6 is vertically downwards inserted, so that the initial positioning of the rod body 2 and the cap body 1 is completed.
In order to improve the reliability of being connected between the spacing inserted block 6 and the body of rod 2, be equipped with the boss 11 in the body of rod 2 and the one end that spacing inserted block 6 is connected, the boss 11 can strengthen the firm degree of being connected between spacing inserted block 6 and the body of rod 2. Meanwhile, considering that the process of rotating and correcting the position of the limiting insert block 6 is taken first, the embedding groove 12 is formed in one end, connected with the vertical rod slot 4, of the position falling groove 5, the requirement that the reinforcing block 11 moves along with the position falling of the limiting insert block 6 can be met, the embedding with the embedding groove 12 is achieved, and the reliability of connection between the limiting insert block 6 and the position falling groove 5 is further improved.
Still be equipped with draw-in groove 13 on the boss 11, be equipped with on the cell wall of caulking groove 12 with draw-in groove 13 complex fixture block 14 (as shown in fig. 7), at the in-process that boss 11 and caulking groove 12 fall the position, fixture block 14 can realize with the synchronous joint of draw-in groove 13, can further improve follow-up use in-process, the atress between spacing inserted block 6 and the groove 5 that falls under the external force application of force state and the stability of force feedback. The surfaces of the clamping blocks 14 are arranged in a prismatic shape, so that the reliability of the clamping blocks 14 and the clamping grooves 13 in a stress state can be guaranteed, and the possibility of breakage and layering between the clamping blocks 14 and the clamping grooves 13 caused by long-time stress is reduced.
As shown in fig. 2 and 4, after the limiting insert block 6 is matched with the falling groove 5, the movement of the limiting insert block 6 in the vertical direction needs to be limited, a fan-shaped sealing block 7 is inserted and slid in the fan-shaped slot 3, and a limiting supplement block 8 (as shown in fig. 5) is further fixed below the fan-shaped sealing block 7 positioned on one side of the vertical rod slot 4 in the pair of fan-shaped sealing blocks 7, namely, in the process of inserting the fan-shaped insert block into the fan-shaped slot 3, the state that the limiting insert block 6 is limited in the falling groove 5 in an abutting mode is achieved. Simultaneously, the gomphosis of 4 parts of montant slot can effectively be realized to spacing mend piece 8, and the one end that spacing mend piece 8 and the body of rod 2 were contradicted still is equipped with arc support portion 17 (as shown in fig. 5), helps reducing the body of rod 2 part and exposes subsequent structure corrosion that probably brought etc. also ensured the complete degree of whole stainless steel fastener structure, also can carry out spacing support to body of rod 2 part to a certain extent, realizes the stability of state in-process such as follow-up application of force locking.
Because the unable stability that realizes sector seal piece 7 of the in-process that sector seal piece 7 was inserted is spacing, be equipped with cooperation lug 16 in one side of sector seal piece 7, lateral wall at another sector seal piece 7 be equipped with cooperation lug 16 complex cooperation recess 15, can assist operating personnel to realize quick location to sector seal piece 7's installation, and can promote the unified work of a pair of sector seal piece 7 under the stress state through cooperation lug 16 with cooperation recess 15's cooperation relation, reduce the dislocation between the sector seal piece 7 that appears and slide etc, ensure the reliable and stable of application of force process.
As shown in fig. 1 and 4, a locking groove 9 is vertically arranged at the end of the cap body 1, the locking groove 9 penetrates through the fan-shaped sealing block 7, a locking rod 10 is inserted into the locking groove 9, and the final limiting fixation of the fan-shaped sealing block 7 can be realized through the matching of the locking rod 10 and the locking groove 9, so that the stable matching between the limiting insertion block 6 part and the falling groove 5 is ensured.
After the equipment that has accomplished this stainless steel fastener is fixed, in order to further improve the structural integrity degree and the product self reliability of this fastener, the outer wall border of fan-shaped sealed piece 7 is equipped with the chamfer, the operating personnel of being convenient for carries out actual welded fastening, the chamfer part has then made things convenient for the inlay card of miniature welding rod, do benefit to the final shaping work after the welding is accomplished, it still overlaps and is equipped with sealed shell 18 (as shown in figure 6) to emit on body 1, can be to the further protection of the fastener after the installation is accomplished, reduce the external environment probably to the erosion of fastener, ensure the reliable intensity of whole stainless steel fastener.
The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present invention.
