Detailed Description

The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.

Referring to fig. 1 to 4, the utility model relates to a locating pin of simple installation of preferred embodiment, including both ends opening, inside hollow body 1, be equipped with in the body and extend to the perforation 2 of terminal surface under the body from the body up end, be equipped with flange plate 3 on the lateral surface of body, the part that the body is located the flange plate top is nail somatic part 4, the part that the body is located the flange plate below is pin somatic part 5, locating pin of simple installation still includes nail core 6, the nail core includes nail core head 8 on nail core bar 7 and the nail core bar, the length of nail core bar is greater than fenestrate length, the nail core bar can penetrate and wear out from the other end of body from the opening of body one end, the size of nail core head is greater than the opening size of perforating being located nail somatic part terminal surface.

The utility model discloses a locating pin simple to handle sets up the flange board on its body lateral surface, and the tip of nail core bar sets up nail core head, and this makes the mode that the operating personnel accessible adopted the riveter to stimulate the nail core bar realize the fixed of pin body portion and installation, and it is easy and simple to handle, weight are light and the difficult not hard up after the installation of pin body portion. When the nail core head is in specific work, an operator firstly penetrates the nail core rod from one end of the nail body part and penetrates out from one end of the pin body part until the nail core head is contacted with the end face of the nail body part. The operator then passes the shank portion through the locating hole 8 in the workpiece and brings the flange plate into surface contact with the workpiece 9. Then the other end of the nail core rod is placed into an input port of the riveter by an operator and is locked, the nail core rod can be pulled by the operator through the riveter after the nail core rod is locked, the nail core rod moves towards the direction of the riveter under the action of the riveter, and therefore the nail core head at the other end of the nail core rod is driven to move towards the direction of the flange plate. Along with the movement of the nail core head, because the size of the nail core head is larger than the size of the opening of the through hole on the end surface of the nail body part, the nail body part can not pass through the opening, the nail body part is gradually bent and deformed under the pressure action of the nail core head until the nail body part forms a drum shape with the middle part expanding outwards and the two ends bending inwards, and the size of the drum shape is far larger than that of the workpiece positioning hole. At the moment, the workpiece is clamped between the flange plate and the deformed drum-shaped nail body, so that the pin body is positioned and fixed. After the fixing is finished, an operator can break off the nail core rod through the riveter, and the nail core rod part connected with the nail core head can be retained in the through hole in an interference fit mode to enhance the strength of the pin body rod. Because the mode that adopts the riveter pulling to install it fixedly, operating personnel can accomplish whole installation fixing process from the one side operation of work piece, compare in traditional mode from two-sided installation, its operation is more convenient, and simultaneously, the shank portion is pressed from both sides tightly through expanded drum nail shank portion and ring flange, and this makes the locating pin less to the aperture required precision of locating hole on the work piece, and the back is difficult not hard up even after the installation, and its holistic weight is also littleer.

Preferably, the locating pin of the utility model discloses an easy installation is provided with rupture groove 10 on the nail core pole.

The arrangement of the breaking groove enables an operator to break the nail core rod more easily.

Preferably, the positioning pin of the present invention is easy to install in that the top end of the pin body is a reducer 11 having a small upper outer diameter and a large bottom outer diameter.

Preferably, the positioning pin of the present invention is easy to install, and the bottom end of the nail body is provided with a nail body groove 12 located on the outer surface of the nail body.

The arrangement of the reducing pipe and the nail body groove enables the nail body to be easily deformed into a drum-shaped structure with two ends contracting inwards and the middle expanding outwards under the pressure of the nail core head. Specifically, the setting of reducing pipe for nail body portion top surface and medial surface all incline to the body inboard, and this makes the reducing pipe have the trend to the motion of body axle center under the effect of nail core head, and the setting of nail body ditch makes the part that the nail body is located near the nail body ditch also have the trend to the motion of body axle center under the effect of its internal stress, and then makes the nail body portion be the middle part inflation, and the drum-shaped structure of the inside body axle center bending of both ends. In specific implementation, the nail body groove is an annular groove with a right-angle section.

Preferably, the positioning pin of the present invention is easy to install, wherein the bottom surface of the pin core head is a ring surface, and the outer edge of the ring surface is lower than the inner edge of the ring surface.

The design further enables the nail body to be more easily deformed into a drum-shaped structure with two ends shrinking inwards and the middle expanding outwards under the pressure of the nail core head. Specifically, the outer edge of the ring surface is lower than the inner edge of the ring surface, so that the ring surface is integrally in a horn shape with a downward opening and is adapted to the inclined outer peripheral surface of the reducer pipe, and the nail body is wrapped in the bottom surface of the horn-shaped nail core head under the action of the pressure of the nail core head, so that the nail body is more easily moved towards the axis direction of the pipe body, and the nail body is deformed into a drum shape.

Preferably, the utility model discloses a simple installation's locating pin is provided with locking tooth 13 on the lateral surface of nail core pole.

The arrangement of the locking teeth enables the nail core rod to be locked with the nail body part through the locking teeth after the nail body part is bent and deformed. During the concrete implementation, operating personnel is through offering a plurality of annular on the nail core pole top is global in order to form above-mentioned locking tooth, and the prong of locking tooth is the slope down to do benefit to locking. The outer diameter of the locking tooth portion may be slightly larger than the diameter of the bore at the top of the bore to facilitate an interference fit. When the nail core rod is installed, the part of the nail body which is bent and deformed is embedded between the locking teeth, so that the nail body and the nail core rod are locked.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that the invention can be implemented in other specific forms by a person skilled in the art without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description.

Furthermore, the above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention. Also, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
