Service HotlineSwimming self-locking nut GJB 125.1～125.6-86 The double-ear sealing swimming self-locking nut is composed of four parts: sealing cover, self-locking nut, pressure ring and sealing ring. It has compact structure and reliable sealing, and is suitable for products whose working pressure is not more than 2atm, working medium is gasoline, kerosene, water or air, and the operating temperature is -50～100℃. However, it has certain difficulties in the manufacturing process and air tightness test.
An elastic cylindrical pin assembling device, the assembling device includes an adapter handle, a punching needle, an elastic piece, a fixed sleeve and a telescopic sleeve, the adapter handle and the fixed sleeve are fixedly connected, and the punching needle is inserted into the adapter handle and fixed Inside the sleeve and its upper end is pressed against the adapter handle, the lower end of the punch needle is also inserted into the fixed sleeve and moves relative to the fixed sleeve in the up and down direction when the adapter handle pushes it to move up and down, the fixed sleeve A reset spring is also set between the punch and the punch, the lower end of the fixing sleeve has an insertion hole for the elastic cylinder pin, that is, a working cavity, and the lower end of the punch needle is also provided with a push fit for the upper end of the elastic cylinder pin. the positioning boss. When the elastic cylindrical pin assembling device is used, after assembling an elastic cylindrical pin, the elastic cylindrical pin needs to be re-installed into the fixed sleeve, which cannot realize continuous assembly and has low assembly efficiency.
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.

Many customers ask what is the difference between a rivet nut and a rivet nut, and how to use it? Let's take a look at the difference between a rivet nut and a rivet nut with Yueluo. First of all, in terms of appearance, you can look at the differences in appearance. In terms of appearance, the difference between the rivet nut and the pressure rivet nut is still very big, but their main functions are almost the same. They all provide threads for thin plates, but the way of installation is different. The method of installation greatly determines the purpose and use of a nut. First of all, the installation method of the riveting nut is to use the riveting equipment to carry out the riveting, so it is suitable for use in the place where the riveting is not easy for the square tube and the round tube. The rivet nut also makes up for some of the shortcomings of electric welding, such as aesthetics, and places that are not easy to weld, such as thin plates.
