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, the present invention provides a technical solution: a nut with a self-locking structure comprises a bolt body 1, a fixing hole 2, a nut body 3, a fixing rod 4, a fixing nut 5, a connecting sleeve 6, a blocking rod 7, a connecting rod 8, a supporting rod 9, a fixing groove 10 and a spring 11, wherein the fixing hole 2 is formed in the side surface of the bolt body 1, the nut body 3 is connected to the side surface of the bolt body 1, the fixing rod 4 and the spring 11 are respectively arranged inside the nut body 3, the fixing rod 4 penetrates through the spring 11, the fixing rod 4 is embedded and installed inside the fixing hole 2, the fixing nut 5 is connected to the side surface of the bolt body 1, the fixing nut 5 is located at the upper end of the nut body 3, the connecting sleeve 6 is fixed to the upper end of the fixing nut 5, the blocking rod 7 is connected to the inside of the connecting sleeve 6, the supporting rod 9 is arranged inside the blocking rod 7, the fixing groove 10 is formed in the side, the upper end of the support rod 9 is connected with a connecting rod 8.
The bolt body 1 is respectively in threaded connection with the nut body 3 and the fixing nut 5, 2 fixing holes 2 are symmetrically arranged in the bolt body 1, the nut body 3 and the fixing rod 4 form a telescopic structure, one end of the fixing rod 4 is an inclined surface, the upper end of the nut body 3 is an inclined surface, when the device is used, the nut body 3 is firstly rotated to be connected with the bolt body 1, one end of the fixing rod 4 is an inclined surface, when the fixing rod 4 is contacted with the bolt body 1, the bolt body 1 can slide along the inclined surface of the fixing rod 4, so that the fixing rod 4 is retracted into the nut body 3, when the nut body 3 moves to a fixing position, the spring 11 pushes the fixing rod 4 to stretch out and embed into the fixing hole 2, so as to fix the nut body 3, then the fixing nut 5 is rotated to be connected with the bolt body 1, and the fixing nut 5 moves downwards, it will contact with the nut body 3 and the nut body 3 will be embedded inside the fixing nut 5, thereby increasing the friction force between the two and preventing the nut body 3 from sliding.
The equal angle of the inside of adapter sleeve 6 is provided with shelves pole 7, and shelves pole 7 and fixed slot 10 block connection, and connecting rod 8 and adapter sleeve 6 constitute dismantlement mounting structure, and connecting rod 8 and bracing piece 9 constitute rotating-structure, and when installing the device, because shelves pole 7 sets up in the inside of fixed slot 10, so can carry on spacingly to bracing piece 9 for bracing piece 9 can only reciprocate in the inside of adapter sleeve 6.
The supporting rod 9 is connected with the connecting sleeve 6 in a sliding manner, the supporting rod 9 is connected with the bolt body 1 in a clamping manner, the connecting rod 8 moves downwards to drive the supporting rod 9 to move downwards, the fixing nut 5 is fixed with the bolt body 1 at the moment, the position of the supporting rod 9 is fixed, when the supporting rod 9 moves downwards, the supporting rod 9 is embedded into the bolt body 1, the connecting rod 8 is rotated, the connecting rod 8 is connected with the connecting sleeve 6 in a threaded manner, the connecting rod 8 and the supporting rod 9 form a rotating structure, the supporting rod 9 is continuously pushed to move downwards so as to fix the supporting rod 9, after the supporting rod 9 is fixed with the bolt body 1, when the fixing nut 5 tends to rotate, the supporting rod 9 cannot rotate due to the clamping between the supporting rod 9 and the bolt body 1, and only the supporting rod 9 and the connecting sleeve 6 can move upwards and downwards, and can not rotate for adapter sleeve 6 can not rotate, because fix between adapter sleeve 6 and the fixation nut 5, and then make fixation nut 5 can not rotate, thereby fix fixation nut 5, when fixation nut 5 is fixed, because fixation nut 5 has limiting displacement to nut body 3, make nut body 3 can not the rebound, thereby increase nut body 3's stability, prevent that nut body 3 from taking place to rotate.
The working principle is as follows: when the nut with the self-locking structure is used, firstly, the nut body 3 is rotated to be connected with the bolt body 1, the nut body 3 can move downwards along with the rotation of the nut body 3, and after the nut body 3 moves to a fixed position, the spring 11 pushes the fixing rod 4 to move inwards, so that the fixing rod 4 is embedded into the fixing hole 2, and the nut body 3 is fixed;
then, the fixing nut 5 is rotated to move downwards, when the fixing nut 5 descends to the bottom, the fixing nut 5 is contacted with the nut body 3, and the inclined surface at the upper end of the nut body 3 is embedded into the fixing nut 5, so that the friction force between the fixing nut 5 and the nut body 3 is increased, and the fixing nut 5 is prevented from rotating;
the stop rod 7 is arranged in the fixing groove 10 in the supporting rod 9, so that the supporting rod 9 can be limited, the supporting rod 9 can only move up and down, the supporting rod 9 is moved to the lower end to be embedded into the bolt body 1, then the connecting rod 8 and the connecting sleeve 6 are rotated to be fixed, the supporting rod 9 is fixed while the supporting rod 9 is pushed to move down, and the installation of the device is completed;
at this moment, the supporting rod 9 is clamped with the bolt body 1, so that the supporting rod 9 is prevented from rotating, and when the supporting rod 9 cannot rotate, the fixing nut 5 cannot rotate, so that the nut body 3 is fixed, and the overall practicability is improved.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
