Description

Novel self-tapping screw

Technical Field

The utility model relates to a self tapping screw technical field especially relates to a novel self tapping screw.

Background

The self-tapping screw is a screw with a drill bit, and drilling, tapping, fixing and locking are completed at one time through construction of a special electric tool. The self-tapping screw is mainly used for connecting and fixing thin plate pieces, such as connection of a color steel plate and a color steel plate, connection of the color steel plate, purlines and wall beams and the like, and the penetration capacity of the self-tapping screw is generally not more than 6mm and maximally not more than 12 mm. The self-tapping screw is often exposed outdoors and has strong corrosion resistance; the rubber sealing ring can ensure that the screw is not seeped with water and has good corrosion resistance.

The existing self-tapping screw is used due to the structural characteristics of the self-tapping screw, when the self-tapping screw is fixed on the surface of an object, the self-tapping screw can rotate reversely, so that the self-tapping screw is separated from a mounting hole, the safety of the object is influenced to a certain degree, and when the screw which is not required to be detached is screwed, the self-locking is required, so that the position stability of the self-tapping screw is ensured.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a: the novel self-tapping screw is provided for solving the problem that the existing self-tapping screw is easy to slide and fall off when in use.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a novel self tapping screw, includes the body, fixedly connected with thread on the outer wall of body, and the top of body has seted up the cross recess, the inside of body is inlayed and is equipped with the slide bar, and fixedly connected with stopper on the slide bar to the position of stopper corresponds the setting with thread position, the top of the outstanding body in top of slide bar.

As a further description of the above technical solution:

the inside of body has seted up the spout, and the spout is located one section and the outside UNICOM of screw thread.

As a further description of the above technical solution:

the bottom fixedly connected with rubber block of slide bar, and interference fit between rubber block and the spout.

As a further description of the above technical solution:

the front side of the limiting block is of a diamond structure, and the side of the limiting block is of a rectangular structure.

To sum up, owing to adopted above-mentioned technical scheme, the beneficial effects of the utility model are that:

the utility model discloses in, clockwise rotating screw, make its embedding treat among the dress thing, strike the top of slide bar, thereby make the slide bar downstream, stopper on the slide bar is through its bottom pointed end treat the dress thing and push away, thereby inlay and establish in the thread groove that non-thread tooth offered, because the bottom fixedly connected with block rubber of slide bar, and damping is great between block rubber and the spout, thereby the slide bar is difficult for deviating from in the spout, when the body has the counter-clockwise turning trend, because the both sides of stopper all are restricted, have the separation effect, thereby self tapping screw's motion is restricted, prevent its phenomenon that the roll-off appears, promote self tapping screw's security.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: the utility model provides a novel self tapping screw, including body 1, fixedly connected with thread tooth 2 on the outer wall of body 1, and cross recess 4 has been seted up at body 1's top, body 1's inside inlays and is equipped with slide bar 3, slide bar 3's the face of looking down all is the arc structure, the external diameter between slide bar 3 and the body 1 is the same, and fixedly connected with stopper 5 on the slide bar 3, and stopper 5's position corresponds the setting with thread tooth 2 position, avoid stopper 5 to cause the hindrance when the screw rotates, the top of the outstanding body 1 in top of slide bar 3.

Specifically, as shown in fig. 1 and 4, a sliding groove 7 is formed in the body 1, the sliding groove 7 is located at one section of the thread teeth 2 and is communicated with the outside, a rubber block 6 is fixedly connected to the bottom end of the sliding rod 3, and the rubber block 6 and the sliding groove 7 are in interference fit, so that the sliding rod 3 is prevented from freely sliding in the sliding groove 7.

Specifically, as shown in fig. 1, fig. 3 and fig. 4, the front side surface of the limiting block 5 is a diamond structure, and the side surface of the limiting block 5 is a rectangular structure.

The working principle is as follows: during the use, play through the screw and cross groove 4 between butt joint, clockwise rotation, thereby make body 1 embedding treat among the dress thing, after rotation to maximum position, strike slide bar 3's top, thereby make slide bar 3 downstream, stopper 5 on the slide bar 3 is through its bottom pointed end to treat the dress thing and push, thereby inlay and establish in the thread groove that non-thread tooth 2 was seted up, because slide bar 3's bottom fixedly connected with block rubber 6, and the damping is great between block rubber 6 and the spout 7, thereby slide bar 3 is difficult for deviating from in the spout 7, when body 1 has the anticlockwise rotation trend, because both sides of stopper 5 are all restricted, have the separation effect, thereby self tapping screw's motion is restricted, prevent its phenomenon that the roll-off appears, promote self tapping screw's security.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
