[ technical field ] A method for producing a semiconductor device

The invention relates to the technical field of nuts, in particular to the technical field of spring nuts.

[ background of the invention ]

The nut is mainly used for connecting parts, a bolt penetrates into a screw hole, and the nut is screwed down by using a tool, so that the connection of the two parts is realized, when the nut is used for a C-shaped steel connecting device, the mounting process of bolt connection is complex, the bearing capacity of the nut is smaller, especially when the connecting position of the C-shaped steel needs to be changed, the bearing capacity of the C-shaped steel needs to be calculated again, and the like, so that the mounting position cannot be changed at will, if the mounting position can be changed after the C-shaped steel is calculated, the material resources and the labor cost of the nut correspondingly increase a plurality of conventional spring-nut springs without plastic films, the springs can be wound together, the packaging is influenced, and the.

[ summary of the invention ]

The invention aims to solve the problems in the prior art, and provides an anti-winding plastic package spring nut convenient to mount, which can avoid winding of a spring and is convenient to package and mount and use on site.

In order to achieve the purpose, the invention provides an anti-winding plastic package spring nut convenient to install, which comprises a spring nut body and a plastic package spring, wherein the spring nut body is a rectangular block, a threaded hole is formed in the spring nut body, the threaded hole penetrates through the upper end and the lower end of the spring nut body, the plastic package spring is vertically arranged at one end of the spring nut body, the plastic package spring and the threaded hole are coaxially arranged, and the diameter of the plastic package spring is larger than that of the threaded hole.

Preferably, the plastic package spring comprises a spring body and a plastic package film, wherein the spring body is vertically arranged at one end of the spring nut body, the center of the spring body is coaxially arranged with the threaded hole, the outer ring of the spring body is wrapped with the plastic package film, and the plastic package film has certain toughness.

Preferably, one end of the spring nut body, which is far away from the plastic package spring, is provided with two sliding grooves, the two sliding grooves are respectively arranged along the short edges of the two sides of the spring nut body, and the two sliding grooves are relatively parallel.

Preferably, a plurality of anti-skid tooth protrusions for preventing skid are arranged in the sliding groove.

Preferably, the short edges at both sides of the spring nut body are provided with fillets which contract inwards at opposite angles.

Preferably, the plastic-sealed spring is installed on the spring nut body through forging and pressing.

The plastic package spring nut with the anti-winding function and the convenient installation function has the beneficial effects that: according to the invention, the spring is arranged at the upper end of the nut, and the spring is wrapped by the plastic packaging film, so that the spring is prevented from being wound, is not easy to deform, is convenient to package and install and use on site, can be protected, and can be prevented from entering the spring by foreign matters, clamping the spring and rusting.
