Bolt not coming loose easily

专利摘要:
PURPOSE: A bolt preventing unfastening is provided to keep coupling to hold an object however the object moves. CONSTITUTION: A plurality of protrusions(1) are formed all over a bottom of a head(2) of a bolt so that lower parts thereof face in coupling direction and higher parts thereof face in releasing direction. The bolt is easily fastened as the protrusions are incapable of resisting while is not easily unfastened as the protrusions hold a bottom of a coupled object by frictional force. The protrusions scratch the bottom of the coupled object even when the bolt is forcibly unfastened to keep the coupling.

专利说明:

Loosening Bolt {Bolt not coming loose easily}
[10] The present invention relates to an anti-loosening bolt having protrusions on the bottom of a bolt head, and more particularly, to an anti-loosening bolt formed on a lower side of a protrusion inclined to the bottom of a bolt head and a high protruding portion toward a dismantling direction.
[11] Conventionally, when a bolt is fastened to an adherend (object to fasten the bolt), when the adherend is loosened due to shaking during transportation or other handling, the entire structure (adherence) is often loosened or disintegrated. There is even the risk that some or all of the structure will be dismantled.
[12] In addition, various loosening bolts have appeared in order to solve the above defects, but the structure is complicated, making the manufacturing and use inconvenient and difficult to obtain a predetermined loosening effect.
[13] The present invention solves the drawbacks of the conventional bolts or bolts to prevent loosening bolts to hold the adherend while the bolt (fixed) to hold the adherend almost without loosening, no matter how the shake (movement) In order to provide a bolt, in particular, a plurality of inclined protrusions are formed on the entire bottom of the head of the bolt, and once tightened, it is difficult to rotate because it rotates while scratching the adherend even if it is not reversed. This will be described in detail with reference to the accompanying drawings as follows.
[1] Figure 1 (a) is a perspective view of one example of the present invention anti-loosening bolt.
[2] Figure 1 (b) is a perspective view of another example of the present invention anti-loosening bolt.
[3] Figure 2 (a) is a front view of Figure 1 (a).
[4] Figure 2 (b) is a front view of Figure 1 (b).
[5] Figure 3 (a) is a bottom view of Figure 2 (a).
[6] Figure 3 (b) is a bottom view of Figure 2 (b).
[7] * Description of the symbols for the main parts of the drawings *
[8] 1,1 ': Bolt head 2: Inclined protrusion
[9] 3: high protrusion part 3 ': low part
[14] Protruding obliquely over the entire bottom of the head 2 of the bolt, the lower part 3 'is formed in the direction of the fastening and the higher part 3 is formed in the form of a plurality of projections 1 which are configured to be directed toward the dismantling direction. .
[15] The loosening bolt of the present invention configured as described above has a plurality of protrusions 1 formed on the bottom surface of the bolt 2, that is, the entire surface of the fastening body (structure), and thus the top of the protrusion 1 Since the high protrusion part 3 is in the disassembly direction of the bolt and its lower part 3 'is formed toward the engagement (fastening) direction of the bolt, the lower part of the bolt when fastening the bolt of the present invention to the fastened body ( It is rotated toward 3 ') and easily fastened, but once the fastened body is rocked or the bolt is pulled out and lowered, the high projecting part 3 of the protrusion 1 formed on the bottom of the bolt head is formed in the dismantling direction of the bolt. The high projecting part 3 of the protrusion 1 is in a state of being held closely to the bottom surface of the object to be attached (to-be-adhered body). Edo bolt (1 Since the high part 3 of the bottom projection is rotated while scratching the bottom surface of the adherend, natural disassembly is almost impossible, and thus it is always possible to keep the fastening tightly.
[16] The anti-loosening bolt of the present invention has an effect of maintaining a safe and complete fastening state forever since the reverse rotation is difficult due to the protrusion (1) of the bottom of the bolt head when the fastening bolt is fastened to one end to be fastened.

权利要求:
Claims (1)
[1" claim-type="Currently amended] It is composed of a plurality of protrusions (1) configured to be inclined over the entire bottom of the head (2) of the bolt, so that the lower portion (3 ') is in the fastening direction and the high protrusion (3) is in the dismantling direction. Characteristic of loosening bolt.
