The novel anti-loosening bolt is further improved in that the limiting piece comprises a stop rod which is guaranteed to be cylindrical, threads are arranged on the periphery of the stop rod, an internal thread is arranged at one end, close to the head of the screw, of the built-in cavity, and the internal thread is matched with the threads on the periphery of the stop rod.
The novel anti-loosening bolt is further improved in that an elastic part is connected between the positioning block and the cavity wall of the built-in cavity.
The novel anti-loosening bolt is further improved in that a second internal thread is arranged in the middle of the built-in cavity, threads are also arranged on the periphery of the ejector rod, and the second internal thread is matched with the threads on the periphery of the ejector rod.
Compared with the prior art, the utility model has the beneficial effects that:
according to the utility model, the positioning block is arranged at the lower end of the bolt cadre, and the positioning block is ejected out to limit the nut of the screw bolt, so that the nut is prevented from loosening and falling off.
Drawings
FIG. 1 is a schematic structural view of the present invention;
in the figure: the bolt comprises a bolt head 1, a bolt rod 2, a built-in cavity 3, a communicating cavity 4, a positioning block 5, a jacking block 6, a jacking rod 7, a limiting part 8 and an elastic part 9.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1, a novel anti-loosening bolt, including integrated into one piece's bolt head 1 and bolt pole portion 2, be provided with built-in chamber 3 in the bolt pole portion 2, 3 one ends in built-in chamber run through bolt head 1 and communicate in the outside, the 3 other ends in built-in chamber are provided with intercommunication chamber 4 to the 2 outsides in bolt pole portion, bolt pole portion periphery between intercommunication chamber 4 and the bolt head 1 is provided with the screw thread, 4 departments in intercommunication chamber are provided with for the gliding locating piece 5 in intercommunication chamber 4, be provided with in built-in chamber 3 and be conical kicking block 6, kicking block 6 supports locating piece 5, be provided with ejector pin 7 in the built-in chamber 3, ejector pin 7 supports kicking block 6, perhaps ejector pin and kicking block body coupling, be provided with locating part 8 on the bolt head 1, locating part 8 is spacing ejector pin 7. Further, locating part 8 is the columniform pin including guaranteeing, the pin periphery is provided with the screw thread, the one end that the built-in chamber is close to the screw rod head is provided with the internal thread, the screw thread looks adaptation of internal thread and pin periphery. The stop lever is provided with a convex part which is convenient to grab. The stop lever carries out rotational positioning for built-in chamber tip, carries out spacingly to the ejector pin. Furthermore, an elastic part 9 is connected between the positioning block and the cavity wall of the built-in cavity. The elastic piece can be a spring, and the positioning block can be automatically retracted into the communicating cavity. Furthermore, a second internal thread is arranged in the middle of the built-in cavity, threads are also arranged on the periphery of the ejector rod, and the second internal thread is matched with the threads on the periphery of the ejector rod. The ejector rod is further fixed, and the internal thread and the second internal thread can have different inner diameters.
The working principle of the utility model is as follows: with bolt and supporting nut looks spiro union fastening, insert the holding chamber with ejector pin and kicking block, the ejector pin is connected with the second internal thread at holding chamber middle part, extrudees the locating piece simultaneously for the intercommunication chamber is stretched out to the locating piece, has realized that the locking of nut is become flexible and has come off, and in order to guarantee the further stability of ejector pin, it is spacing to conflict to the ejector pin to use the locating part of spiro union at built-in chamber tip, and simple structure has on the whole prevented taking off of nut.
It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof.
