SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a locking self-locking fastener to it is through the thread tightening to propose the fastener in solving above-mentioned background art, but the fastener is after matcing with the object screw thread, owing to rock the fastener condition that becomes flexible can appear, thereby can lead to the problem of the condition that the fastener drops.
In order to achieve the above object, the utility model provides a following technical scheme: a locking self-locking fastener comprising: the connecting rod is fixedly connected to the bottom of the cap head, the threaded column is fixedly connected to one end of the bottom of the connecting rod, the threaded column is connected to the inside of the threaded groove in a matched mode, the threaded groove is formed in the connecting piece, and the secondary mounting assembly is pressed at the top of the threaded column.
Preferably, the secondary mounting assembly comprises a threaded sleeve and a cushion block, and the cushion block is fixedly connected to the top of the threaded sleeve.
Preferably, the bottom of the threaded sleeve is pressed on the top surface of the threaded column, and the threaded sleeve is in threaded fit connection with the threaded groove.
Preferably, the outer side of the cushion block is arranged between the cap head and the connecting piece, and the cushion block and the inner part of the thread sleeve are simultaneously connected with the connecting rod in a penetrating mode.
Preferably, a sliding groove is formed in the cushion block, a limiting pin is movably connected to the inside of the sliding groove, and a shifting block is fixedly connected to one end of the limiting pin.
Preferably, the surface of the cap head is provided with a clamping hole, and the size of the clamping hole is matched with that of the limiting pin.
Compared with the prior art, the beneficial effects of the utility model are that: this locking auto-lock fastener through the cap head, connecting rod, screw thread post, thread groove, connecting piece, thread bush, cushion, spacer pin, shifting block and the mutually supporting of structure between the card hole for install screw thread post and thread bush in the inside back of connecting piece, can form the structure of auto-lock between screw thread post and the thread bush two, can effectually avoid appearing not hard up condition after screw thread post and the thread bush installation.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the 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. 1-3, the present invention provides a technical solution: a locking self-locking fastener comprising: the cap head 1, the bottom fixedly connected with connecting rod 2 of cap head 1, the bottom one end fixedly connected with screw thread post 3 of connecting rod 2, screw thread post 3 mating connection is in the inside of thread groove 4, the inside at connecting piece 5 is seted up to thread groove 4, the top of screw thread post 3 is still pressfitting has inferior installation component.
Referring to fig. 1 and 2, the mounting assembly includes a threaded sleeve 6 and a cushion block 7, the cushion block 7 is fixedly connected to the top of the threaded sleeve 6, and the cap head 1 can be locked and limited by the mutual matching between the threaded sleeve 6 and the cushion block 7.
Referring to fig. 1 and 2, the bottom of the threaded sleeve 6 is pressed on the top surface of the threaded post 3, and the threaded sleeve 6 is in threaded fit connection with the threaded groove 4, and the threaded sleeve 6 is pressed on the threaded post 3, so that the threaded sleeve 6 and the threaded post 3 are self-locked with each other.
Referring to fig. 1 and 2, the outer side of the spacer 7 is disposed between the cap head 1 and the connecting member 5, the connecting rod 2 is simultaneously connected to the inside of the spacer 7 and the threaded sleeve 6 in a penetrating manner, and the connecting rod 2 penetrates the inside of the spacer 7 and the threaded sleeve 6, so that the connecting rod 2 can rotate inside the spacer 7 and the threaded sleeve 6.
Referring to fig. 1 and 2, a sliding groove is formed in the cushion block 7, a limit pin 8 is movably connected in the sliding groove, a shifting block 9 is fixedly connected to one end of the limit pin 8, and the shifting block 9 drives the limit pin 8 to slide in the sliding groove in the cushion block 7 by pushing the shifting block 9.
Referring to fig. 1, 2 and 3, a clamping hole 10 is formed on the surface of the cap head 1, the size of the clamping hole 10 is matched with the size of the limit pin 8, and the limit pin 8 can limit the cap head 1 by mutually clamping the limit pin 8 and the clamping hole 10.
In summary, the following steps: as shown in fig. 1-3, when the anti-loose self-locking fastener is used, the shifting block 9 is firstly pushed, so that the shifting block 9 drives the limit pin 8 to be inserted into the clamping hole 10, then the cap head 1 and the cushion block 7 are simultaneously rotated, so that the threaded column 3, the threaded sleeve 6 and the threaded groove 4 are in threaded matching with each other, the threaded column 3 and the threaded sleeve 6 can be assembled inside the connecting piece 5, then the shifting block 9 is loosened, so that the limit pin 8 is separated from the cap head 1 under the action of gravity, then when the threaded sleeve 6 and the threaded column 3 are singly loosened, the threaded sleeve 6 and the threaded column 3 are pressed to be limited with each other, the situation that the threaded sleeve 6 and the threaded column 3 are loosened can be effectively avoided, and then the self-locking of the threaded sleeve 6 and the threaded column 3 is formed, which is the characteristic of the anti-loose self-locking fastener.
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.
