The invention discloses a tightening deformation locking bolt. The tightening deformation locking bolt is composed of a special-shaped bolt, a cap nut, a rectangular sleeve part and a spacer, wherein one end of the special-shaped bolt is a head portion; the other end of the special-shaped bolt is a fixing rod; the middle of the special-shaped bolt is a screw rod with outer threads; the cap nut is provided with a nut body, a cap and a fixing hole; the special-shaped bolt and the cap nut are spaced by the spacer; the cap and the nut body on the cap nut are connected together; the fixing hole is formed in the inner top face of the cap; the internal height of the cap nut is greater than the length of the fixing rod; when the fixing rod penetrates through the nut body to the fixing hole in the inner top face of the cap, the screw rod on the special-shaped bolt is combined with the nut body on the cap nut, and the locking effect is achieved through rotating; the shape of the special-shaped bolt and the cap nut can be mechanically machined and manufactured, so that the production cost is relatively low, and large-scale production can be achieved. The tightening deformation locking bolt has good market prospects.

The invention discloses an anti-loosing screw nut which comprises a screw nut mounting sleeve, a driving screw nut and a locking screw nut, wherein the driving screw nut is mounted inside the screw nut mounting sleeve; a driving part is arranged above the driving screw nut; a shrinking part is arranged below the locking screw nut; a plurality of insert slots are formed in a side wall of the shrinking part in an axial direction; the shrinking part is driven by the driving part to shrink in a radial direction; a plurality of clamping strips are arranged above the shrinking part; annular limiting grooves are formed in the inner wall of the screw nut mounting sleeve; end parts of the clamping strips are driven by the driving part to be expanded in the radial direction and embedded into the annular limiting grooves. As the shrinking part of the locking screw nut is controlled to shrink in the radial direction by the driving screw nut, the radial connection pretightening force of a bolt can be increased, the anti-loosing purpose is achieved, meanwhile the bolt is driven to drive the clamping strips to be embedded inside the screw nut mounting sleeve, the locking screw nut and the screw nut mounting sleeve are locked, connection stability is ensured, and the anti-loosing effect is further improved.

The invention discloses a locking releasing-preventive hexagon nut which comprises a hexagon nut body and a screw hole. A transverse wedge-shaped slot is arranged on the hexagon nut body, and the depth of the wedge-shaped slot is proper so that the wedge-shaped slot reaches the center line of the screw hole. The locking releasing-preventive hexagon nut has the advantages of simple structure, convenience in installation, high safety performance and high practicality.

The invention relates to an anti-loosening device for the light-distribution regulation of a lamp and a lamp using the anti-loosening device. The anti-loosening device comprises a rotating ring rotationally sleeved on a lamp main body, and an anti-loosening elastic sheet fixed on the lamp main body, wherein the rotating ring rotates to drives a light-distribution regulation device which is connected with the rotating ring to adjust the focus of the lamp; and a plurality of continuous anti-loosening parts are further arranged on the inner surface of the rotating ring, and the end part of the anti-loosening elastic sheet is sequentially contacted with the side surfaces of the plurality of anti-loosening parts during the rotating process of the rotating ring, so as to generate a resistance opposite with the rotating direction of the rotating ring. The lamp comprises the lamp main body, the light-distribution regulation device and the anti-loosening device. The anti-loosening device for the light-distribution regulation of a lamp and the lamp using the anti-loosening device disclosed by the invention achieve the anti-loosening purpose by utilizing the matching of the anti-loosening elastic sheet and the anti-loosening parts on the inner surface of the rotating ring, and can effectively prevent the problem of unstable light distribution due to the loosening which is brought by vibration, rapid movement and the like during a light-distribution regulation process; and the lamp using the anti-loosening device is more accurate in light distribution.

The invention discloses a slide buckle type locknut mainly applied to the mechanical field; the slide buckle type locknut has an interlocking function, and is easy to manufacture and use, and the locknut can be further reused; the locknut is composed of a nut A and a nut B; according to the working principle of the locknut, the nut B is firstly tightened on a bolt so that a workpiece is pressed bythe lower end of the nut B, and then the nut A is tightened on the bolt with the extrusion portions facing downwards; the upper ends of a plurality of columns of the nut A are slide along the lower ends of the threaded segments of a plurality of slide buckle convex ribs of the nut B, the upper ends of the columns and the lower ends of the threaded segments of the slide buckle convex ribs are extruded mutually and deformed elastically; after the multiple columns of the nut A enter the half-arc segments of the corresponding multiple slide buckle convex ribs of the nut B, the multiple columns ofthe nut A are restored elastically; interlocking between the nut A and the nut B is achieved; meanwhile, a plurality of arc segments of the nut B are extruded by the extrusion portions of the nut A,and external threads of the bolt are extruded by internal threads B of the multiple arc segments, so that the external threads of the bolt are tightly clamped, and the purpose of anti-looseness is achieved.
