Detailed Description
The following description is presented to disclose the invention so as to enable any person skilled in the art to practice the invention. The preferred embodiments in the following description are given by way of example only, and other obvious variations will occur to those skilled in the art. The basic principles of the invention, as defined in the following description, may be applied to other embodiments, variations, modifications, equivalents and other technical solutions without departing from the spirit and scope of the invention.
Fig. 1 to 4 illustrate an impact bar according to the spirit of the present invention, the impact bar includes a cylindrical connecting portion 1, at least one cylindrical impact portion 2 and a mounting portion 3, the impact portion 2 and the mounting portion 3 are respectively located at different ends of the connecting portion 1, and the connecting portion 1, the impact portion 2 and the mounting portion 3 are of an integral structure. That is, the connecting portion 1, the striking portion 2, and the mounting portion 3 of the striking rod are integrally formed.
Specifically, the connecting portion 1 has a first end 11 and a second end 12 opposite to the first end 11, the impact portion 2 integrally extends from the first end 11 of the connecting portion 1, and the mounting portion 3 integrally extends from the second end 12 of the connecting portion 2. As shown in fig. 4, the central axis of the connecting part 1 is consistent with the central axis of the impact part 2, and the diameter of the connecting part 1 is larger than that of the impact part 2, so that the connecting part 1 is thicker and stronger, and the impact bar is not easy to bend and deform when the impact bar is used, thereby being beneficial to ensuring the reliability and stability of the impact bar.
As shown in fig. 1 to 4, the impact bar includes two impact portions 2 respectively defined as a first impact unit 21 and a second impact unit 22, the first impact unit 21 integrally extends from the first end portion 11 of the connecting portion 1, the second impact unit 22 integrally extends from the first impact unit 21, a diameter dimension of the first impact unit 21 is smaller than a diameter dimension of the connecting portion 1, and a diameter dimension of the second impact unit 22 is smaller than a diameter dimension of the first impact unit 21, so that surfaces of the impact bar formed on the second impact unit 22, the first impact unit 21 and the connecting portion 1 are stepped surfaces. And, by forming the second impact unit 22 and the first impact unit 21, the impact bar is adapted to impact one implosion piece 5 having different inner diameter sizes, so as to improve the practicality of the impact bar.
Optionally, the impact bar comprises one of the impact portions 2, and the surfaces of the impact bar formed at the impact portion 2 and the connecting portion 1 form a stepped surface.
Preferably, the mounting portion 3 has four flat mounting surfaces 31, and the adjacent mounting surfaces 31 are perpendicular to each other, so that the cross-sectional shape of the mounting portion 3 is square, so that the mounting stability of the impact bar and the impact drill 4 can be improved after the mounting portion 3 of the impact bar is mounted to the impact drill 4 to form an electric hammer by the impact bar and the impact drill 4. More preferably, each cover mounting surface 31 of the mounting portion 3 is provided with at least one recess 32, and the length direction of the recess 32 coincides with the length direction of the mounting surface 31, so that a projection in the mounting port of the hammer drill 4 can be further engaged in each recess 32 of the mounting portion 3, thereby further increasing the stability of the mounting relationship of the hammer drill 4 and the hammer rod.
In a variant of the striker bar shown in fig. 5, the mounting portion 3 of the striker bar is a magnetic mounting portion, for example, first a magnet 100 is provided, then a cylindrical blank is formed outside the magnet 100 by casting, and then the blank is processed by a machine tool (lathe or milling machine) to form the connecting portion 1 of the striker bar, the striker portion 2 integrally extending from the connecting portion 1, and the mounting portion 3 integrally extending from the connecting portion 1, wherein the magnet 100 is located at the position of the mounting portion 3 so that the mounting portion 3 forms a magnetic mounting portion, so that, when the mounting portion 3 of the striker bar is placed in the mounting hole of the striker drill 4 without being tightened, the mounting portion 3 can attract each other with the mounting hole of the striker drill 4 so that the mounting portion 3 is stably held in the mounting hole of the striker drill 4, thereby facilitating the mounting of the impact rod to the percussion drill 4 by the operator, which is necessary when working aloft, for example when the operator is standing on a ladder.
Fig. 6 to 11 show the process of striking the implosion piece 5 into a wall 6 using the electric hammer formed of the impact bar and the impact drill 4. As shown in fig. 7, a hole 61 is formed in the wall 6 by means of an electric drill or the like, and the size of the hole 61 is consistent with the size of the implosion member 5 before a deformable technical shell 51 is deformed; as shown in fig. 8, the deformable metal case 51 of the implosion piece 5 is placed in the opening 61 of the wall 6, and then a core 52 of the implosion piece 5 is placed inside the deformable metal case 51. As shown in fig. 9 and 10, the second impact unit 22 of the impact portion 2 of the impact rod is pressed against the iron core 52 of the implosion piece 5, and the impact drill 4 is operated such that the impact drill 4 provides an impact force to the impact rod to continuously impact the iron core 52 by the impact rod, so that the iron core 52 continuously enters the inside of the deformable metal shell 51, during which the deformable metal shell 51 is continuously expanded inside the wall 6. It can be understood that as the depth of the core 52 that is impacted into the inner space of the deformable metal shell 51 increases, the deformable metal shell 51 expands more, so that the deformable metal shell 51 is stably held in the opening 61 of the wall 6. After the impact is completed, the hammer with the impact bar can be removed, as shown in fig. 11. As shown in fig. 6 to 11, in the process of impacting the implosion piece 5 on the opening 61 of the wall 6 by using the electric hammer, the operator does not need to hold the impact rod by hand, so as to avoid injury to the hand of the operator due to misoperation, and the operator does not need to manually hammer the impact rod to impact the implosion piece 5, so that the whole process is more labor-saving.
The foregoing is illustrative of the preferred embodiments of the present invention only, and is not to be construed as limiting the claims. The present invention is not limited to the above embodiments, and the specific structure thereof is allowed to be changed. All changes which come within the scope of the independent claims of the invention are to be embraced within their scope.
