Detailed Implementation
[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Please see Figure 1 , Figure 2 and Figure 3 One embodiment of this utility model provides a corrosion-resistant and long-life titanium alloy fastener, comprising a fastener body 1, an I-beam steel plate 2, and fixing connection holes 3. The I-beam steel plates 2 are stacked, and the fastener body 1 is distributed at both ends of the two I-beam steel plates 2. The fixing connection holes 3 are evenly opened through the I-beam steel plates 2. The fastener body 1 includes a second fixing connection bolt 8 and a clamping connection limiting frame 9. Four clamping connection limiting frames 9 are provided and evenly distributed. The second fixing connection bolt 8 is threaded into the middle of the clamping connection limiting frame 9.
[0018] A fixed threaded connecting plate 4 is provided between the middle of the four clamping and limiting frames 9. The bottom end of the fixed threaded connecting plate 4 is threaded into the two ends of the two I-shaped steel plates 2.
[0019] An auxiliary reinforcing connecting plate 6 is fixedly connected to the inner end of the locking and limiting frame 9 by the first fixing connecting bolt 7. The auxiliary reinforcing connecting plate 6 has auxiliary reinforcing holes 5 evenly distributed through it, so that the auxiliary reinforcing connecting plate 6 plays the role of reinforcing connection.
[0020] The bottom inner side of the locking and limiting frame 9 is symmetrically provided with auxiliary fixing connection holes 10.
[0021] The two ends of the I-shaped steel plate 2 are secured inside the clamping connection limit frame 9, and the second fixed connection bolt 8 is threaded through the two I-shaped steel plates 2 to fix and tighten them.
[0022] The fixed threaded connecting plate 4, the auxiliary reinforcing connecting plate 6, the first fixed connecting bolt 7, the second fixed connecting bolt 8, and the clamping connecting limit frame 9 are all made of titanium alloy. Furthermore, the outer end faces of the fixed threaded connecting plate 4, the auxiliary reinforcing connecting plate 6, the first fixed connecting bolt 7, the second fixed connecting bolt 8, and the clamping connecting limit frame 9 are all provided with a zinc-nickel alloy protective layer, which makes the fixed threaded connecting plate 4, the auxiliary reinforcing connecting plate 6, the first fixed connecting bolt 7, the second fixed connecting bolt 8, and the clamping connecting limit frame 9 corrosion resistant and have a long service life.
[0023] Working principle: During use, after the two I-beam steel plates 2 are aligned and overlapped, the various locking and limiting frames 9 in the fastener body 1 are locked and placed at the respective end corners of the I-beam steel plates 2. Then, the second fixing bolt 8 is threadedly inserted into the locking and limiting frames 9 and the two I-beam steel plates 2, thereby limiting and fixing the end corners of the I-beam steel plates 2. This allows the two I-beam steel plates 2 to fit together securely. When the two I-beam steel plates 2 are large, the fixing threaded connecting disc 4 is threaded inside the two ends of the two I-beam steel plates 2. Then, the two ends of the auxiliary reinforcing connecting plate 6 are fixedly connected between the fixing threaded connecting disc 4 and the locking and limiting frames 9 by the first fixing bolt 7. This makes the individual locking and limiting frames 9 and the fixing threaded connecting disc 4 form a whole, allowing for a more secure connection between the two I-beam steel plates 2. This increases the strength of the I-beam steel plates 2 after the connection is secured. The auxiliary fixing connection hole 10 at the bottom of the limiting frame 9 allows each locking and connecting limiting frame 9 to be firmly set, ensuring that both ends of the two I-shaped steel plates 2 are fully tightened and fixed. The fixing threaded connecting plate 4, auxiliary reinforcing connecting plate 6, first fixing connecting bolt 7, second fixing connecting bolt 8, and locking and connecting limiting frame 9 are all made of titanium alloy. The outer end faces of the fixing threaded connecting plate 4, auxiliary reinforcing connecting plate 6, first fixing connecting bolt 7, second fixing connecting bolt 8, and locking and connecting limiting frame 9 are all provided with a zinc-nickel alloy protective layer. The protective layer has good corrosion resistance and bonding strength, which can effectively protect the fixing threaded connecting plate 4, auxiliary reinforcing connecting plate 6, first fixing connecting bolt 7, second fixing connecting bolt 8, and locking and connecting limiting frame 9, which are made of titanium alloy, from corrosion by corrosive media, thus greatly increasing the service life of the fixing threaded connecting plate 4, auxiliary reinforcing connecting plate 6, first fixing connecting bolt 7, second fixing connecting bolt 8, and locking and connecting limiting frame 9 used for fastening.
[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
