Service HotlineAt present, the connecting shafts of commonly used food processing knives on the market generally use square bayonet, which is not easy to install parts, and it is time-consuming and laborious when replacing parts; Increased processing costs. There is also a link structure with a circular bayonet on the market, but it is easy to loosen and not firm after the entire food processor is used for a period of time, which affects the use of the machine. Therefore, a connection structure that is easy to operate and simple to process is urgently needed.
series of nuts are known in the prior art, generally comprising an internal thread which can be threaded onto the external thread of a screw of corresponding design, or a threaded bolt. Nuts of the described type are used, for example, as nuts for fastening screw-like cable connections in conduits of sheet metal housings. Sheet metal housings of this type typically have walls so thin that they cannot be threaded, so a threaded connection of this type is required to complete the installation.
The purpose of Guangdong Yueluo Hardware Industry Co., Ltd. is to provide a bayonet which is a T-shaped cylindrical pin with a misaligned through hole at the head, and a bayonet spring which is a ring-shaped spring steel wire whose ends are staggered. The retaining ring is clamped by the bayonet pin to fix the stop sleeve and the pin shaft together. A hydraulic excavator pin stopper with high disassembly and assembly efficiency and no need for a wrench. The technical solution of Guangdong Yueluo Hardware Industry Co., Ltd. is such that it includes a latch, a stop sleeve, a pin, a bayonet, and a circlip. The staggered end is clamped into the misaligned through hole of the plug, and screwed on the bottom of the stopper sleeve to fix the stopper sleeve and the pin shaft together. The latch is composed of a bayonet pin and a circlip, the circlip is screwed around the through hole of the bayonet pin to the root of the bayonet pin, and the stopper sleeve is tightly wrapped around the pin shaft, and the circlip is tightly against the bayonet pin. The head of the bayonet pin has two T-shaped cylindrical pins with staggered through holes, and the circlip is an annular spring steel wire whose ends are staggered. By adopting the pin shaft stopping method of the above technical scheme, it is extremely convenient and quick to disassemble and assemble the pin shaft. The bolt of Guangdong Yueluo Hardware Industry Co., Ltd. is only composed of a T-shaped cylindrical pin with two staggered through holes in the head and a ring-shaped spring steel wire with staggered ends. The structure is simple, convenient to manufacture, low cost and obvious. It is an excavator pin stop method with high disassembly and assembly efficiency, no need for a wrench and low manufacturing cost.
An anti-loosening nut structure includes a flat nut and an oblique nut. One end surface of the oblique nut is an oblique surface, and an angle is formed between the oblique surface and the vertical line of the screw hole axis of the oblique nut. Nuts are installed on the bolts one after another, and the mating contact surfaces of the two nuts include the inclined surface, which are tightened in sequence.
Guangdong Yueluo Hardware Industry Co., Ltd. discloses a telescopic screw. The main point of its technical solution is that it includes an upper screw rod, one end of the upper screw rod is provided with a screw head, and the other side of the upper screw rod opposite to the screw head is provided with a lower screw rod, and the lower screw rod is provided on the other side. A fixing rod is provided, a limiting hole is set on the fixing rod, a sliding rod is set on the upper screw rod, a limiting block matching the limiting hole is set on the sliding rod, and a cover plate is slidably sleeved on the sliding rod. An inner thread is arranged on the plate, a thread matching the inner thread is arranged on the fixing rod, an elastic member is sleeved on the fixing rod, and both ends of the elastic member are respectively in conflict with the upper screw rod and the lower screw rod. Guangdong Yueluo Hardware Industry Co., Ltd. telescopic screw is provided with a telescopic mechanism between the upper screw and the lower screw. Therefore, the screw can be suitable for threaded installation holes with the same diameter and different lengths, avoiding the screw being limited by the length of the threaded hole and unable to be installed.
