Description

Impact adapter and impact tool set including the same

The present invention relates to a disassembly device, and in particular to an impact adapter and an impact tool kit comprising the same.

Mechanical transmission and connection are commonly seen in various devices, such as the parallel rod of a car (commonly known as a Li Zai string), which is connected between the left and right shock absorbers or tripods through a monk head. When replacing it, the traditional method is to use a hammer to directly hit the monk head, hoping that the impact will cause the monk head to move and then remove the plugged object. This disassembly and assembly method is time-consuming and labor-intensive, and often causes the monk head to change shape, be damaged, and cannot be used again.

Therefore, it is necessary to provide a novel and advanced impact adapter and an impact tool set including the same to solve the above problems.

The main purpose of the present invention is to provide an impact adapter and an impact tool set including the same. The impact adapter can indirectly transmit the impact force to the object to be disassembled, so it can effectively ensure the structural integrity of the object to be disassembled without being deformed or damaged due to direct knocking.

To achieve the above-mentioned purpose, the present invention provides an impact adapter, comprising: a connecting portion, a body portion and a bearing portion. The connecting portion is provided with a threaded hole, and the threaded hole is provided for threading to a screw of an object to be disassembled. The body portion is connected to the connecting portion. The bearing portion is connected to a side of the body portion away from the connecting portion, and the bearing portion provides an impacting effect of an impact member.

To achieve the above purpose, the present invention further provides an impact tool set, comprising: an impact adapter as described above and an impact member, the impact member comprises a corresponding joint portion and an impact head, the joint portion and the receiving portion are matched and assembled with each other, and the impact head is assembled with the impact device.

The following examples are only used to illustrate possible implementations of the present invention, but they are not intended to limit the scope of protection of the present invention. The "one" or "at least one" before the terms mentioned in the text does not limit the quantity. It can also be "plural" according to needs. This change in quantity is also within the scope of protection, which should be explained first.

Please refer to Figures 1 to 5, which show an embodiment of the present invention. The impact adapter 1 of the present invention includes: a connecting portion 2, a body portion 3 and a receiving portion 4.

The connecting portion 2 is provided with a threaded hole 21, and the threaded hole 21 is provided for a screw 72 that is threadedly connected to an object to be disassembled 71 (such as a monk head), so that the impact adapter 1 can be stably combined with the object to be disassembled 71 to form a synchronous relationship. The body 3 is connected to the connecting portion 2, and the bearing portion 4 is connected to a side of the body 3 away from the connecting portion 2. The bearing portion 4 provides an impact member 6 for impact, whereby the bearing portion 4 can indirectly transmit the impact force received to the object to be disassembled 71 through the body 3 and the connecting portion 2, and the impact member 6 will not directly impact the object to be disassembled 71, thereby ensuring the structural integrity of the object to be disassembled 71 and surrounding components.

The receiving portion 4 includes a boss 41 and a non-circular base 42, the base 42 is connected to the body 3, and the boss 41 protrudes from the base 42. When the impact adapter 1 is tightly engaged with the screw 72 and cannot be rotated relative to it by hand, the non-circular base 42 allows the user to drive the impact adapter 1 to rotate with the aid of other rotating tools (such as a wrench); wherein the outer diameter of the boss 41 is smaller than the outer diameter of the base 42, and the boss 41 and the base 42 form a first step 43, and the first step 43 can be used for the impact member 6 to abut against, so as to increase the contact area between the impact member 6 and the impact adapter 1, so that the impact force can be evenly transmitted. Similarly, the outer diameter of the base 42 is preferably smaller than the outer diameter of the body 3, and the base 42 and the body 3 form a second step 44 for the impact member 6 to abut against.

In this embodiment, the impact adapter 1 further includes an axial direction 53. In the axial direction 53, the length of the boss 41 is greater than the length of the base 42. When the impact member 6 and the impact adapter 1 are plugged and combined with each other, the longer boss 41 can penetrate deeper into the impact member 6 to improve the stability of the combination of the two. In addition, the boss 41 is a cylinder, and the base 42 is a hexagonal column. When the impact member 6 is sleeved to the base 42, the hexagonal base 42 can prevent the impact member 6 and the impact adapter 1 from rotating relative to each other during the impact process, which can improve the stability of the impact process. In addition, the side of the protrusion 41 away from the base 42 is a cone with a flat top, which can greatly increase the contact area between the protrusion 41 and the impact member 6, and has a better uniform impact force effect.

Preferably, the body 3 is provided with an anti-slip structure 51, which includes a plurality of annular grooves 511 arranged at intervals to increase the contact area between the hand and the body 3, thereby achieving the purpose of improving the holding stability; wherein, each annular groove 511 is cut and formed on the body 3, and the body 3 has a thicker radial dimension, therefore, each annular groove 511 is selected to be formed on the body 3 to ensure that the structural strength of the impact adapter 1 will not be affected.

Another preferred embodiment is to provide a marking portion 52 on the body 3, which is used to correspond to the thread specifications of the threaded hole 21, so that the user can quickly identify the size; based on the same reason as above, the marking portion 52 is cut and formed on the body 3.

It is worth mentioning that the extension length of the threaded section of the threaded hole 21 is preferably no longer than 15 mm, so that the screw rod 72 of various lengths can actually hit the hole wall of the threaded hole 21, increasing the contact area between the screw rod 72 and the impact adapter 1. In this embodiment, the depth of the threaded hole 21 is equal to the length of the bearing portion 4.

The present invention also provides an impact tool set, including: the impact adapter 1 and the impact member 6, the impact member 6 includes a relative joint portion 61 and an impact head 63, the joint portion 61 and the receiving portion 4 are matched and assembled with each other, and the impact head 63 is assembled with the impact device; wherein the joint portion 61 is sleeved with the boss 41 and the base 42.

The impact member 6 further includes an extension portion 62, which is cylindrical and includes a first radial section 621 and a second radial section 622. The radial dimension of the second radial section 622 is larger than the radial dimension of the first radial section 621, and has the effect of uniformly dispersing the impact force. The first radial section 621 and the second radial section 622 are connected at the outer contour to form a first arc. The concave portion 64, the first arc concave portion 64 can smoothly transmit the impact force, the first radial section 621 is connected to the impact head 63, the second radial section 622 is connected to the joint portion 61, the radial dimension of the joint portion 61 is larger than the radial dimension of the second radial section 622, and the joint portion 61 and the second radial section 622 are connected at the outer contour to form a second arc concave portion 65.
