Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-4, in an embodiment of the present invention, a laminated expansion bolt includes a T-shaped bolt 1 and a bolt 4, the T-shaped bolt 1 is provided with a plurality of limiting holes 2, the limiting holes 2 include a first hole 11 and a second hole 12, the diameter of the first hole 11 is greater than the diameter of the second hole 12, the diameter of the first hole 11 is smaller than the diameter of the T-shaped bolt 1, the upper end of the T-shaped bolt 1 is provided with a fixing hole 3, the diameter of the fixing hole 3 is the same as the diameter of the upper end of the bolt 4, the bolt 4 is provided with a threaded area 5, the length of the threaded area 5 is smaller than the length of the bolt 4, a warning line 6 is arranged above the threaded area 5, the lower end of the bolt 4 is provided with a limiting rod 7, the diameter of the bolt 4 is greater than the diameter of the limiting rod 7, the limiting rod 7 is fixedly connected with the bolt 4, the lengths of the bolt 4 and the limiting rod 7 are respectively smaller than the length of the T-shaped bolt 1, and the total length of the screw 4 and the limiting rod 7 is smaller than the length of the T-shaped bolt 1, a fixing ball 8 is arranged in the T-shaped bolt 1 corresponding to the position of the limiting holes 2, the diameter of the fixing ball 8 is smaller than that of the first hole 11, the diameter of the fixing ball 8 is larger than that of the second hole 12, a spring 9 is arranged between the fixing ball 8 and the limiting holes 2, a threaded pipe 10 is arranged above the fixing ball 8 in the T-shaped bolt 1, the screw 4 is connected with the T-shaped bolt 1 through the threaded pipe 10, and the limiting rod 7 is inserted between the fixing balls 8.
The utility model discloses a theory of operation is:
when the utility model is used, the T-shaped bolt 1 is arranged at the position of the required installation, because the limiting rod 7 is arranged between the fixed balls 8 and the limiting rod 7 is smaller than the diameter of the screw 4, when the limiting rod 7 is arranged between the fixed balls 8, the fixed balls 8 extrude the fixed balls 8 towards the limiting rod 7 under the action of the spring 9, therefore, the T-shaped bolt 1 can not influence the normal use due to the blocking of the fixed balls 8, when the firmness between the T-shaped bolt 1 and the connecting object needs to be increased through the fixed balls 8, the screw 4 is rotated to move towards the bottom end of the T-shaped bolt 1 under the action of the threaded pipe 10, thereby, the lower end of the screw 4 is inserted between the fixed balls 8, because the diameter of the screw 4 is larger than the diameter of the limiting rod 7, therefore, the screw 4 can extrude the fixed balls 8 towards the direction of the first hole 11, because the fixed balls 8 are smaller than the diameter of the first hole 11, the fixing ball 8 is continuously pressed towards the second hole 12, because the diameter of the fixing ball 8 is larger than that of the second hole 12, part of the volume of the fixing ball 8 protrudes out of the surface of the T-shaped bolt 1, so that the fixing ball 8 tightly abuts against the contact part of the T-shaped bolt 1 and the connection object, and the T-shaped bolt 1 and the connection object are fixed more firmly, when the T-shaped bolt 1 needs to be disassembled, the screw 4 is rotated by the screwdriver to separate the lower end of the screw from the fixing ball 8, the limiting rod 7 is positioned between the fixing balls 8, so that the spring 9 re-presses the fixing ball 8 into the T-shaped bolt 1, then the T-shaped bolt 1 is taken out by the wrench, the prompting wire 6 can determine the position of the limiting rod 7, when the prompting wire 6 is exposed out of the fixing hole 3, the prompting wire 7 is about to separate from the fixing ball 8, when the prompting wire 6 is not exposed out of the fixing hole 3, the prompting wire 7 is still inserted between a plurality of the fixing balls 8, thereby preventing the user from completely pulling out the screw 4 and damaging the T-bolt 1.
The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
