Description

Technical Field

[0001] This utility model relates to the field of power tool accessories technology, specifically to an electric hammer adapter. Background Technology

[0002] A hammer drill adapter is a device used to connect a hammer drill to different types of tools or accessories. In construction, decoration, and other fields, users need to use hammer drills to perform various tasks such as drilling and screwing. However, different tasks require different tools, such as drill bits and electric wrench sockets. To avoid frequently changing tools or purchasing multiple pieces of equipment, hammer drill adapters have emerged. They enable hammer drills to be compatible with various accessories, achieving functional versatility and improving tool utilization.

[0003] Currently available hammer drill adapters are relatively simple to use. Generally, workers can disassemble and replace drill bits and impact drill bits by pulling the limiting sleeve on the adapter. However, existing hammer drill adapters still have some shortcomings. During operation, workers often change multiple drill bit models, so the limiting sleeve is frequently driven when using the adapter. Most of the limiting sleeves on existing adapters only have anti-slip grooves for anti-slip purposes. Over time, due to the presence of many fine sand particles in the working environment, the anti-slip grooves on the surface of the limiting sleeve will wear down, causing the grooves on the surface of the limiting sleeve to become flat. This reduces the surface friction of the limiting sleeve, making it more difficult for workers to drive the limiting sleeve when using the adapter. In addition, the smooth surface of the limiting sleeve can cause it to return to its original position when changing drill bits, affecting the efficiency of drill bit changing. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an electric hammer converter, which solves the problem that the anti-slip grooves on the surface of the limiting sleeve in traditional electric hammer converters are easily worn, making it difficult to drive the limiting sleeve. It also improves the anti-slip performance of the limiting sleeve surface in the converter, reduces the trouble for workers, and prevents the limiting sleeve from returning to its original position when changing drill bits due to the smooth surface of the limiting sleeve during use, thus preventing the impact on the efficiency of changing drill bits.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an electric hammer converter includes a mounting base, a support platform fixedly connected to the upper surface of the mounting base, a support column fixedly connected to the upper surface of the support platform, an installation rod fixedly connected to the upper end of the support column, four sets of limiting grooves on the upper side surface of the installation rod, an installation hole through the lower surface of the mounting base, a locking mechanism on the side surface of the support column, a limiting sleeve on the side surface of the installation rod, three sets of anti-slip blocks on the outer side of the limiting sleeve, multiple anti-slip strips fixedly connected to the outer surface of the anti-slip blocks, an installation block fixedly connected to the inner surface of the anti-slip blocks, hemispherical grooves symmetrically formed on the upper and lower surfaces of the installation block, and an installation component on the outer surface of the limiting sleeve.

[0006] Preferably, the mounting component includes a mounting groove, one end of which has a sliding groove, the lower end of which passes through a limiting sleeve. A hemispherical protrusion is fixedly connected to the inner wall of the mounting groove by a spring piece. The hemispherical protrusion is slidably connected to the limiting sleeve, and the hemispherical protrusion corresponds to the hemispherical groove.

[0007] Preferably, the locking mechanism includes limiting holes, which are symmetrically opened on the side surface of the support column. One end of the limiting hole passes through the support column and communicates with the mounting hole. A limiting ball is provided inside the limiting hole.

[0008] Preferably, the upper end of the limiting sleeve has a slot, and the upper side surface of the support column has an annular limiting groove. The slot and the annular limiting groove correspond to each other. The upper end of the limiting sleeve is provided with a retaining ring, and the retaining ring is installed inside the slot.

[0009] Preferably, a protruding ring is fixedly connected to the inner wall of the limiting sleeve, and a spring is provided below the protruding ring. The upper end of the spring is located inside the limiting sleeve, and the lower end of the spring rests on the upper surface of the support platform.

[0010] Preferably, the anti-slip strips on the outer surface of the anti-slip block are arranged in a stepped manner, and the anti-slip strips are made of wear-resistant rubber strips.

[0011] This utility model provides an electric hammer converter. Compared with the prior art, it has the following advantages: the anti-slip strip fixedly connected to the outer surface of the limiting sleeve and the anti-slip block fixedly connected to the outer surface of the anti-slip strip, the mounting block fixedly connected to the inner surface of the anti-slip strip and the hemispherical groove opened on the mounting block, and the mounting components on the outer surface of the limiting sleeve cooperate with each other, solving the problem that the anti-slip groove on the surface of the limiting sleeve in traditional electric hammer converters is easily worn, making it difficult to drive the limiting sleeve. It also improves the anti-slip performance of the limiting sleeve surface in the converter, reduces the trouble for workers, and avoids the limiting sleeve returning to its original position when changing drill bits due to the smooth surface of the limiting sleeve during use, thus preventing the impact on the efficiency of changing drill bits.

The lower end of the sliding groove 305 passes through the limiting sleeve 3. The inner wall of the installation groove 303 is fixedly connected to a hemispherical protrusion 304 by a spring piece. The hemispherical protrusion 304 is slidably connected to the limiting sleeve 3. The hemispherical protrusion 304 corresponds to the hemispherical groove 502. Through the cooperation between the hemispherical protrusion 304 in the installation component and the hemispherical groove 502 on the installation block 503, it is possible to easily install and remove the anti-slip block 5, and to easily replace the new anti-slip block 5 to ensure the anti-slip performance of the limiting sleeve 3.

[0017] As a technical optimization of this utility model, the locking mechanism includes a limiting hole 107, which is symmetrically opened on the side surface of the support column 102. One end of the limiting hole 107 passes through the support column 102 and communicates with the mounting hole 106. A limiting ball 6 is provided inside the limiting hole 107. The limiting ball 6 inside the limiting hole 107 and the limiting hole 107 communicate with the mounting hole 106, which facilitates limiting the replacement drill bit and prevents the drill bit from falling off.

[0018] As a technical optimization of this utility model, the upper end of the limiting sleeve 3 is provided with a slot 301, and the upper side surface of the support column 102 is provided with an annular limiting groove 105. The slot 301 and the annular limiting groove 105 correspond to each other.

Next, the operator inserts the limiting ball 6 into the annular limiting groove 105, and simultaneously pushes the limiting sleeve 3 downwards so that the lower end of the limiting sleeve 3 covers the outside of the limiting ball 6. Then, the retaining ring 4 is fastened into the retaining groove 301 and the annular limiting groove 105, thus limiting the position of the limiting sleeve 3. Finally, the operator applies the protective... The mounting block 503 on the inner surface of the slider 5 is aligned with the slide groove 305, and then slides to the upper end of the slide groove 305. After that, the anti-slip slider 5 is rotated. At this time, the mounting block 503 moves inside the mounting groove 303. When it passes the hemispherical protrusion 304, it is squeezed. Then the hemispherical protrusion 304 will be locked inside the hemispherical groove 502, thereby positioning the anti-slip slider 5. Then, when in use, the operator can pull the limiting sleeve 3 through the anti-slip slider 5 to move it, thereby replacing the drill bit inside the mounting hole 106, avoiding the slippage caused by the wear of the anti-slip groove on the side surface of the limiting sleeve 3.
