Service HotlineThe purpose of Guangdong Yueluo Hardware Industry Co., Ltd. is to provide an improved lock nut to solve the problem that the production technology of the prior art products is too complicated. For realizing the above-mentioned purpose, Guangdong Yueluo Hardware Industry Co., Ltd. adopts following technical scheme—a kind of locking nut, which comprises that the bottom of the nut is a circle, the middle part is a hexagon, and the top is a circle, and there are bolts in the center.
Spring mattresses and spring seat cushions are modern and commonly used furniture products with better performance, and their cushion cores are composed of springs. It makes full use of the advantages of good spring elasticity, good support, strong air permeability and durability. The traditional spring pad is a spring with a thicker wire diameter, which is connected and fixed by steel wires, and has high hardness. Most of the elders of the older generation often use linked spring beds, but if they sleep in a fixed position for a long time or are accustomed to sitting on the side and corners of the bed, or flip the mattress irregularly, it is easy to cause depression and elastic fatigue.
It can be seen from the figure that no matter how the screw core swings, it will not fall off from the screw sleeve. This is because part of the bead 5 is stuck in the hole 6 of the screw sleeve 1 and the other part is stuck in the screw core 2. In the groove 8, it plays the role of positioning. If the screw sleeve rotates clockwise, the beads 5 can only slide in the groove 8 of the screw core 2 under the driving of the screw sleeve 1 and cannot drive the screw core 2 to rotate. If the screw sleeve 8 rotates in the opposite direction, the bead 5 will be stuck on the stop 7 of the screw core 2 so as to drive the screw core 2 to rotate.
A double-nut self-locking fastener includes bolts, nuts, nuts, and elastic gaskets that can produce plastic deformation under pressure; the nut and the bolt are connected by threads, and one end of the nut is provided with an external thread; There is an inner thread in one end, and the inner thread of the nut and the outer thread of the nut constitute a thread pair; the other end of the nut is provided with a through hole, and the bolt passes through the through hole of the nut; when the nut and the nut are installed and tightened, the elastic gasket is located in the nut. between the bolt and the nut; a notch for cutting off the thread is arranged on the circumference of the bolt thread; the direction of the notch is parallel to the axial direction of the bolt.
A nut provided by Yueluo. The nut is in the shape of a sleeve and has a threaded section inside. An annular groove is set on the inner wall of one end of the threaded section. The notch of the groove points to the hole core. The hole diameter at the groove notch at the front end is larger than the nominal size of the thread segment or the hole diameter at the groove notch at the rear end in the screwing direction is smaller than the nominal size of the thread segment.
