Description

Embedded bolt

Technical Field

The utility model relates to a bolt technical field especially relates to an embedded bolt.

Background

Bolt: mechanical parts, cylindrical threaded fasteners fitted with nuts; a fastener consisting of a head and a screw is matched with a nut and used for fastening and connecting two parts with through holes. This form of connection is called a bolted connection; if the nut is unscrewed from the bolt, the two parts can be separated, so that the bolt connection belongs to detachable connection.

Most of the existing bolts are of an integrated structure, and when the bolts are positioned in screw holes and are broken, the bolts are very inconvenient to take out, so that great troubles are caused; and current bolt is most not set up anti-skidding mechanism, leads to when the organism takes place to vibrate, and the bolt very takes place to become flexible easily, drops even, influences equipment safety in utilization.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a: the embedded bolt is provided for solving the problems that the existing bolt is not easy to take out due to fracture in a screw hole and is easy to slide and loosen in equipment.

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

the utility model provides an embedded bolt, includes the head, and the bottom central point of head puts department integrated into one piece has the screw rod, and sets up the screw thread on the screw rod, the spout has been seted up to the inside of screw rod, and the inside slide bar that is equipped with that inlays of spout to weld between slide bar and the head, the cover is equipped with C shape ring on the screw rod.

As a further description of the above technical solution:

the sliding groove is in transition fit with the sliding rod.

As a further description of the above technical solution:

the screw rod is provided with a limiting groove, the limiting groove and the C-shaped ring are in radial transition fit and axial transition fit, and the limiting groove and the C-shaped ring are in rotating connection.

As a further description of the above technical solution:

the sliding groove and the sliding rod are in regular hexagon structures.

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

1. the utility model discloses in, when unscrewing the bolt, if fracture happens carelessly, will inlay and pull out locating the inside slide bar of screw rod through mechanisms such as magnet to twist the slide bar through the allen key and move, because the transition fit between slide bar and the spout, thereby make the slide bar can further advance further rotating to the screw, when avoiding the bolt to break, the problem that can't take out promotes bolt's suitability.

2. The utility model discloses in, carry out the rotating through instruments such as spanner to the head of bolt, thereby in precessing the screw rod in the screw, when the screw rod reaches certain degree of depth in the screw, laminate between the inner wall of C shape ring and screw, when the bolt continues to move downwards, contact between screw and the C shape ring, it extrudees the C shape ring inboard, final C shape ring joint is on the top of screw, because the screw rod passes through spacing groove and C shape between the ring axial spacing, thereby prevent that the bolt from roll-off in the screw, promote bolt's stability.

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. 1-3, the present invention provides a technical solution: the utility model provides an embedded bolt, includes head 1, and head 1 is regular hexagon structure, and the bottom central point of head 1 puts department integrated into one piece has screw rod 2, and sets up screw thread 3 on the screw rod 2, and spout 6 has been seted up to the inside of screw rod 2, and 6 inside inlays of spout and is equipped with slide bar 7 to welding between slide bar 7 and the head 1, the cover is equipped with C ring 5 on the screw rod 2, and trapezoidal structure is personally submitted in the side of

C ring

5, and 2 outer walls of outstanding screw rod.

Specifically, as shown in fig. 2 and 3, the sliding groove 6 and the sliding rod 7 are in transition fit, the cross-sectional surfaces of the sliding groove 6 and the sliding rod 7 are both in regular hexagon structures, and through the fit of the two regular hexagon structures, the situation that the strength of the screw rod 2 is reduced due to the discontinuous structure is reduced, and the strength of the bolt is ensured.

Specifically, as shown in fig. 1-3, a limiting groove 4 is formed on the screw rod 2, and the limiting groove 4 is in radial transition fit with the C-shaped ring 5, and in axial transition fit, axial limiting and radial movement are ensured, and the limiting groove 4 is rotatably connected with the C-shaped ring 5.

The working principle is as follows: when the bolt is used, the head part 1 of the bolt is rotated by a tool such as a wrench, so that the screw rod 2 is screwed into the screw hole, when the screw rod 2 reaches a certain depth in the screw hole, the C-shaped ring 5 is attached to the inner wall of the screw hole, when the bolt continues to move downwards, the screw hole is contacted with the C-shaped ring 5, the C-shaped ring 5 is extruded inwards, finally the C-shaped ring 5 is clamped at the top end of the screw hole, and the bolt 2 is axially limited between the limiting groove 4 and the C-shaped ring 5, so that the bolt is prevented from sliding out of the screw hole, and the stability of the bolt is improved; when unscrewing the bolt, if fracture happens carelessly, the slide bar 7 embedded in the screw rod 2 is pulled out through mechanisms such as magnets, so that the slide bar 7 is screwed through an inner hexagonal wrench, and due to transition fit between the slide bar 7 and the sliding groove 6, the slide bar 7 can further rotate the screw rod 2, the problem that the bolt cannot be taken out when breaking is avoided, and the applicability of the bolt is improved.

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.
