Self-tapping screw with gasket for limiting

Technical Field

The utility model belongs to the technical field of the screw is relevant, concretely relates to take spacing self-tapping screw of gasket.

Background

The self-tapping screw is a connecting part capable of connecting different parts, the self-tapping screw is generally provided with a self-tapping thread which is rotatably clamped and a screwdriver slot which is convenient for a screwdriver to rotate, and when some self-tapping screws are connected with some parts with larger gaps, an elastic pad is arranged on the screw; tapping screws are generally made of stainless steel material in order to prevent rusting. The head of the self-tapping screw in the prior industry is small in size, and if the gap of a fixed part is too large, a gasket needs to be additionally arranged, so that time and labor are wasted, and the production cost is increased; the thread on the screw rod of the self-tapping screw in the industry is arranged from the upper part to the bottom part, so that the screw does not have a smooth buffer area, and equipment is easily damaged due to the extrusion of the screw when the screw is screwed down; the nut of the self-tapping screw in the industry has no corresponding protection measures, and the nut is exposed to air for a long time, so that the nut is easily corroded.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a screw is from taking bullet pad, the screw is screwed up and is difficult to strut equipment and the nut has the difficult spacing self-tapping screw of taking the gasket that has the safeguard measure and is difficult by the corruption.

In order to achieve the above object, the utility model provides a following technical scheme: a self-tapping screw with a gasket for limiting comprises a screw body, wherein a cushion block is machined at the upper top end of the screw body; springs are uniformly and fixedly arranged on the lower bottom surface of the cushion block at intervals; the lower end of the spring is fixedly provided with an elastic pad; a smooth sliding rod is processed on the screw body; the elastic pad is sleeved on the optical slide rod; the screw body is also provided with self-tapping threads; the upper surface of the cushion block is provided with a knob table; the outer side wall of the knob table is uniformly provided with anti-skid edges at intervals; a boss is machined on the upper surface of the knob table; a screwdriver groove is formed in the boss; the upper surface of the cushion block is also provided with a clamping groove; the inside card of draw-in groove is equipped with the protection casing.

As a further improvement of the utility model, the upper surface of the protective cover is provided with a handle.

As a further improvement, the screw body is made of stainless steel material.

As a further improvement of the utility model, the surface of the screw body is plated with anti-corrosion zinc.

As a further improvement of the utility model, the perpendicular alternately link up of screwdriver groove is seted up and is processed there are two.

Compared with the prior art, the beneficial effects of the utility model are that: according to the technical scheme, the cushion block is arranged on the screw body, and the cushion block can be used for conveniently connecting and mounting parts with larger gaps, so that a gasket is not required to be added again, the cost is saved, and the time and the trouble are saved; according to the technical scheme, the spring is arranged on the cushion block, the spring pad is arranged on the spring, and when the screw body is screwed down, the spring is extruded by the spring pad, so that the elastic tension between the spring pad and a fastened part is increased, and the screw body can be mounted more firmly and is not easy to fall off; according to the technical scheme, the smooth sliding rod is arranged on the screw body, so that the phenomenon that the self-tapping threads are screwed too deeply to extrude equipment and damage the equipment is avoided; according to the technical scheme, the knob table is arranged on the cushion block, the anti-skid edges, the bosses and the screwdriver grooves are arranged on the knob table, and the screwdriver grooves are formed in a through and vertical crossing mode; the anti-slip edge can avoid the phenomenon of slipping when the knob is turned; the clamping groove is formed in the cushion block, the protective cover is arranged in the clamping groove, and the protective cover can effectively prevent the rotary knob platform and the boss from being exposed in the air for a long time, so that the rotary knob platform and the boss are corroded and damaged.
