Description

Novel self-locking bolt

Technical Field

The utility model relates to a novel self-locking bolt.

Background

The bolt is a fastener consisting of a head part and a screw rod and is used for fastening and connecting two parts with through holes.

In particular, in order to ensure the connection tightness when the vehicle is assembled, the individual components are connected by means of bolts, which are mutually engaged with nuts in the prior art, and the components are fixed by means of extrusion.

However, for some parts exposed to the outside and having relatively high value, the bolt has only a fixing function and is relatively insufficient, and thus, there is a need for a self-locking bolt having an internal locking structure.

Disclosure of Invention

The utility model aims to provide a novel self-locking bolt so as to solve the problems in the prior art.

In order to solve the technical problems, the utility model provides the following technical scheme: comprises a right threaded rod;

the lower surface of the right threaded rod is provided with a rotatable left threaded rod, and the lower surface of the left threaded rod is provided with a locking rod;

the inside carousel that is provided with of left threaded rod, the inside movable block that is close to left threaded rod side of locking lever is provided with the ability locking carousel.

Preferably, the lower surface of the right threaded rod is provided with a bearing rod, and the locking rod is arranged on the bearing rod.

Preferably, the lower surface of the rotary table is provided with a plurality of tooth blocks in a circumferential array, and the upper surface of the moving block is provided with an inserting block.

Preferably, the locking rod is provided with a polygonal groove.

Preferably, a screw is arranged at one end of the polygonal groove, which is close to the moving block, and the moving block is arranged on the screw.

Preferably, a screwing block is arranged on the upper surface of the right threaded rod.

Preferably, the locking rod is threaded in the same direction as the right threaded rod.

Compared with the prior art, the utility model has the beneficial effects that:

when the device is used, the whole device is inserted into the hole of two parts, the polygonal groove is rotated, the plug-in block on the surface of the movable block is driven by the action of screw threads to separate from the surface of the toothed block, the nut is inserted into the locking rod and screwed up by the threads, when the threads on the nut are mutually contacted with the left threaded rod, the left threaded rod is driven to rotate under the action of the threads and the extrusion until the two parts are completely connected, after the connection is finished, the polygonal groove is rotated, the plug-in block is reinserted onto the toothed block to complete the locking, thus the device is locked from the inside by the positive and negative thread structure, the whole device is locked from the inside by the thread structure in two directions, and the whole device has a certain anti-theft effect when being fastened, so the whole device can be widely applied to automobile assembling bolts.

In the figure: 1. a right threaded rod; 2. a left threaded rod; 3. a locking lever; 4. a carrier bar; 5. a turntable; 6. tooth blocks; 7. a moving block; 8. polygonal grooves; 9. a screw; 10. a plug block; 11. and screwing the block.

Detailed Description

In order to solve the problem conveniently, the embodiment of the utility model provides a novel self-locking bolt. The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-3, the present embodiment provides a novel self-locking bolt, which includes a right threaded rod 1;

the lower surface of the right threaded rod 1 is provided with a rotatable left threaded rod 2, and the lower surface of the left threaded rod 2 is provided with a locking rod 3;

the inside carousel 5 that is provided with of left threaded rod 2, the inside movable block 7 that is close to left threaded rod 2 side that is provided with of locking lever 3 can lock carousel 5.

Specifically, the lower surface of the right threaded rod 1 is provided with a bearing rod 4, and the locking rod 3 is arranged on the bearing rod 4; the right threaded rod 1 and the locking rod 3 are connected by a carrier rod 4.

Specifically, a plurality of tooth blocks 6 are arranged on the lower surface of the turntable 5 in a circumferential array, and a plug-in block 10 is arranged on the upper surface of the moving block 7; the locking of the turntable 5 is completed by inserting the plug-in block 10 into the tooth block 6.

Specifically, the locking rod 3 is provided with a polygonal groove 8; by virtue of the polygon shape of the polygonal groove 8, a general tool cannot be inserted, and the overall locking capability is increased.

Specifically, a screw rod 9 is arranged at one end of the polygonal groove 8, which is close to the moving block 7, and the moving block 7 is arranged on the screw rod 9; by the threaded contact of the screw rod 9 and the locking rod 3, the moving block 7 can be driven to move up and down when the screw rod 9 rotates.

Specifically, the upper surface of the right threaded rod 1 is provided with a screwing block 11; the whole body is convenient to screw and install by screwing the block 11.

Specifically, the thread direction of the locking rod 3 is the same as the thread direction of the right threaded rod 1; the locking rod 3 is thus threaded in the opposite direction to the left threaded rod 2.

Although embodiments of the present utility model 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 therein without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
