Abstract

An impact disassembly device is provided, including an adapter and a first impact rod. The adapter consists of a body and a ball head, with the ball head protruding from one side of the body. A screw hole is located on the side of the body opposite the ball head, intended for securing the adapter to an object for disassembly using a screw rod. The first impact rod comprises a joint part and an impact head. The joint part is designed to detachably slide against the ball head, allowing the first impact rod to be deflected relative to the body, using the ball head as the axis. This flexibility allows for the initial adjustment of the punching angle of the first impact rod, adapting to the surrounding environment.

Description

Impact removal device

The present invention relates to a disassembly device, and in particular to an impact disassembly device.

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 disassembly device to solve the above problems.

The main purpose of the present invention is to provide an impact disassembly device. The adapter can be assembled on the screw of the object to be disassembled to form a common component, and then cooperate with the first impact rod to abut against it for impact, which can effectively ensure the structural integrity of the object to be disassembled, and will not be deformed or damaged due to direct knocking. In addition, when there is no sufficient margin space above the object to be disassembled for knocking, the first impact rod abutting against the ball head of the adapter can be adjusted to a suitable angle to facilitate the knocking operation.

To achieve the above-mentioned purpose, the present invention provides an impact disassembly device, including: an adapter and a first impact rod. The adapter includes a body and a ball head, the ball head is convexly arranged on one side of the body, and a screw hole is arranged on the side of the body away from the ball head, and the screw hole is used to be screwed to a screw of a to-be-disassembled object; the first impact rod includes a relative joint and an impact head, the joint can be detachably slid on the ball head, and then the first impact rod can be deflected relative to the body with the ball head as the axis.

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 6, which show an embodiment of the present invention. The impact disassembly device of the present invention includes: an adapter 1 and a first impact rod 2.

The adapter 1 includes a body 11 and a ball head 17. The ball head 17 is protruding from one side of the body 11. A screw hole 14 is provided on the side of the body 11 away from the ball head 17. The screw hole 14 is used to be screwed to a screw rod 41 of an object 4 to be disassembled (such as a ball joint), so that the adapter 1 and the object 4 to be disassembled are combined into a component and maintain a synchronous motion relationship.

The first impact rod 2 includes a relative joint 21 and an impact head 24. The joint 21 can be detachably slid against the ball head 17, and the first impact rod 2 can be deflected relative to the body 11 with the ball head 17 as the axis. The user can freely adjust the angle position of the first impact rod 2 against the ball head 17 to effectively avoid surrounding obstacles, so as to perform the striking action in a place with sufficient space margin.

Specifically, the joint 21 surrounds a chamber 22, and the joint 21 is sleeved on the ball head 17. The center of the ball head 17 is located in the chamber 22, so that the joint 21 fully covers the ball head 17, ensuring that the first impact rod 2 can be stably assembled to the adapter 1 during the striking process. Specifically, the joint 21 does not completely cover the ball head 17, and the joint 21 can have a wider range of deflection for users to adjust. The volume of the ball head 17 exposed in the chamber 22 is preferably smaller than the volume of the ball head 17 in the chamber 22, so as to have both sleeve connection stability and swing range.

The joint part 21 further includes a joint wall 23 surrounding the chamber 22, and a first gap 31 is defined between the joint wall 23 and the ball head 17. The first gap 31 can give the joint part 21 a smoother relative movement to the ball head 17, reduce the interference between the joint wall 23 and the ball head 17 during the movement process, and reduce the contact friction resistance. In this embodiment, the joint wall 23 is in an arc shape, and the curvature radius of the joint wall 23 is greater than the curvature radius of the ball head 17, thereby forming the first gap 31 between the joint wall 23 and the ball head 17; wherein, the first gap 31 surrounds the ball head 17 and can provide the joint part 21 with ample movement space at various angles in the circumferential direction.

Preferably, a cutting plane 18 is provided at the top of the ball head 17, and the cutting plane 18 and the joint wall 23 define a second gap 32, and the second gap 32 is not connected to the first gap 31, that is, the contacting part of the joint wall 23 and the ball head 17 is limited between the first gap 31 and the second gap 32, thereby controlling the position and transmission path of the force after the impact. In addition, the above contact method can effectively concentrate the force, ensuring that when the first impact rod 2 is struck in a state of tilting the adapter 1, the impact component force can be concentrated and transmitted along the extension direction of the adapter 1, and can effectively force the object 4 to be disassembled to move. In this embodiment, the force of the first impact rod 2 acts on the outer periphery of the cutting plane 18. Similarly, the second gap 32 can also enable the joint 21 and the ball head 17 to slide relative to each other more smoothly, reducing the contact area and concentrating the force.

Specifically, the body 11 further includes a head 12 with a non-circular outer contour and a columnar body 13, the head 12 is connected between the body 13 and the ball head 17, and the body 13 is provided with the screw hole 14; for example but not limited to, the head 12 is in a polygonal column shape, and the body 13 is in a cylindrical shape, and the head 12 can be clamped by another hand tool and rotated relative to the screw 41.

More specifically, the outer diameter of the head 12 is smaller than the outer diameter of the body 13, and the head 12 and the body 13 form a step 15. When the hand tool is sleeved and clamped on the head 12, the hand tool can be pressed against the step 15, so that the step 15 can provide support for the hand tool to rotate stably without shaking. In addition, in the extension direction of the screw hole 14, the ratio of the size of the ball head 17 to the size of the screw hole 14 is between 0.6 and 0.8, so that the two have an appropriate structural ratio.

In this embodiment, the adapter 1 defines an axis 16, and the ball head 17 is coaxially arranged with the body 11. In the direction perpendicular to the axis 16, the ball head 17 does not protrude from the head 12, so that the hand tool can be smoothly inserted without unexpected interference.

Here, another embodiment as shown in FIG. 7 and FIG. 8 is provided, where the body 11A further includes a first component 5 and a second component 6.

The ball head 17A is provided on one side of the first component 5, the screw hole 14 is provided on one side of the second component 6, and one of the other side of the first component 5 and the other side of the second component 6 is provided with a first joint recess 51 and a joint protrusion 61 whose structures and shapes match each other. The joint protrusion 61 is a non-spherical structure, and the first joint recess 51 can be detachably sleeved on the joint protrusion 61; wherein, the second component 6 can be used alone so that the user can have more forms to choose from. Specifically, the joint protrusion 61 can be detachably assembled with a second joint recess 71 of a second impact rod 7, and the structure of the second joint recess 71 matches the joint protrusion 61.
