By means of the universal check bolt, a traditional bolt can be directly replace, so that the universality is better; and the universal check bolt is prevented from being completely locked, later disassemblyand maintenance are facilitated, and the universal check bolt is easy and convenient to assemble and disassemble.

The invention discloses a buckling connection structure between a locking board surface and a board. The connecting structure includes a main groove arranged on a first board body and a main tenon arranged on a second board body, and also includes: The auxiliary tenon provided on the first plate body is provided with an elastic seam, and the elastic seam separates the auxiliary tenon into a first elastic tongue part and a second elastic tongue part; and an auxiliary tenon arranged on the second plate body The groove has a first obstacle structure on its first side groove surface and the first elastic tongue, and a second obstacle structure on its second side groove surface and the second elastic tongue, wherein the auxiliary tenon The first elastic tongue and the second elastic tongue are squeezed into the auxiliary groove when the main tenon enters the main groove. The invention realizes the anti-loosening effect of the main tenon, and at the same time, it produces a butt-in-position indicating sound and a docking-in-position feel, which obviously improves the floor paving experience of the decorator.

The invention relates to the technical field of assembly of automobile parts, in particular to a grooving pressure clamp for a locking nut of a main speed reducer. The grooving pressure clamp comprises a pressing clamp fixing base and a positioning rod fixing base arranged on the pressing clamp fixing base; the two ends of the pressing clamp fixing base are oppositely equipped with a fixed pressure clamp and an oil cylinder; a piston rod end of the oil cylinder perpendicularly points to the fixed pressure clamp; a slide pressing clamp is fixedly arranged on the piston rod; the slide pressing clamp and the fixed pressing clamp are oppositely arranged, and the bottom end of the slide pressing clamp and the bottom end of the fixed pressing clamp are positioned on the same horizontal line; the bottom end of the slide pressing clamp is equipped with a blunt knife edge type pressure head; and a bump type pressure head is arranged at the bottom end of the fixed pressing clamp. The grooving pressure clamp can replace a conventional manual locking mode, so that grooving and pressing consistency and reliability of the locking nut of the main speed reducer are guaranteed, anti-loosening effect is realized better, and the automatic production development direction is met better.

The invention discloses a flange nut for a building support, which comprises a nut body, a flange plate, a threaded through hole, a clamping block installation groove, a clamping block, an inclined plane, a locking groove and a limiting plate. Compared with the prior art , the present invention has simple structure and reasonable design, can improve the connection stability and reliability of flange nuts, prevent nuts from loosening during service, and ensure the structural stability and reliability of building supports.

The invention discloses a novel mechanical locking nut connection locking structure. The mechanical locking nut connection locking structure comprises a nut, a screw rod and a small screw. A thread hole is formed in the center of the nut; an internal thread is arranged in the thread hole; an annular nut body is arranged on the outer side of the thread hole of the nut; multiple through holes are annularly distributed on the nut body; the screw rod is provided with a screw rod body and a screw rod cap; and the screw rod body is columnar, and is provided with an external thread on the outer side.Multiple axial polish holes are formed in the nut; a small thread hole is formed in the shaft shoulder end surface of the screw rod; and the small screw with a spring is provided. When the locking isneeded after tightening of the nut, a front fine cylinder (smaller than the diameters of the polish holes of the nut) of the small screw is screwed out from the polish holes of the nut to prevent thenut from rotating relative to the screw rod so as to achieve the locking effect.

The invention discloses an anti-loosening and anti-vibration screw assembly, which comprises a screw head, a transition section, a stud, an anti-loosening and anti-vibration gasket, a nut and a nut anti-loosening part, the bottom of the screw head is provided with a transition section, and the The bottom of the transition section is provided with a stud, the stud is provided with a nut anti-loosening part, the nut anti-loosening part and the outer side of the stud are provided with an anti-loosening anti-vibration gasket and a nut, and the anti-loosening and anti-vibration gasket It is located between the transition section and the nut. Compared with the prior art, the present invention has a simple structure and a reasonable design. The vibration of the device is effectively absorbed by the first buffer pad and the second buffer pad in the screw assembly, and the vibration is reduced to fasten the screw assembly. The influence of the effect can ensure the stability and reliability of the connection between the connecting parts for a long time.

The invention discloses a locknut and an application method thereof. The locknut comprises a nut body in threaded connection with a threaded shaft, wherein a wedge block groove is formed in one side,close to the threaded shaft, on the nut body; a wedge block is arranged in the wedge block groove; a pressing block groove is formed in one side, directly facing the threaded shaft, on the wedge blockgroove; a pressing block capable of moving along the radial direction of the nut body is arranged in the pressing block groove; one side of the wedge block fits to an external screw thread on the threaded shaft; the other side of the wedge block fits to the pressing block; the horizontal width of the pressing block is larger than the horizontal width of the wedge block; the thickness of one end,close to the unscrewing direction of the nut body, on the wedge block is larger than the thickness of the other end; and a pressing mechanism for driving the pressing block to apply a pressing force on the wedge block is arranged between the nut body and the pressing block. The locknut provided by the invention is good in locking effect; and during application, the locking effect can be achieved only through one nut, and the threaded shaft has no need to be lengthened, so that the space occupation of the threaded shaft on the device is reduced, and the cost is saved.
