Description

Technical Field

[0001] This invention relates to an inertial hammer, specifically a hammer capable of striking a nail using inertia, belonging to the field of hardware technology equipment. More particularly, it relates to an inertial hammer that, after striking a nail once with an impact hammer block, utilizes the inertial force of the falling inertial block to strike the nail a second time, while simultaneously allowing the worker to hold the hammer with both hands and apply force through a hinged structure of the split hammer rod. Background Technology

[0002] A hammer is a tool used to strike objects to move or deform them. Its most common form consists of a hammer head and a hammer shaft. However, when using a hammer to strike nails, it often requires repeated blows, which is slow and inefficient. Also, because the hammer shaft is relatively short, when holding it with both hands, the person's shoulders and arms tend to hunch inwards, making it difficult to apply the full force of both arms to the hammer body. Therefore, it can only be used with one hand, making the method of use rather limited.

[0003] Publication No. CN203141451U discloses a shock-absorbing hammer, including a hammer handle and a hammer body, and a groove set in the hammer body. A fixing block is provided in the groove. The upper and lower end faces of the fixing block are provided with hydraulic upgrading rods. The fixing block is provided with a fixing groove and an internal thread. The hammer handle is installed in the fixing groove, and the front end of the hammer handle is provided with an external thread that mates with the internal thread. The internal cavity of this hammer only serves to absorb shock and cannot assist in striking. Moreover, it is inconvenient for people to hold and use with both hands.

[0004] CN207256157U discloses a detachable multi-purpose hammer for machinery, including a stainless steel hammer head. The stainless steel hammer head includes a stainless steel hammer column, a claw hammer body, and a round-headed hammer body. Both ends of the stainless steel hammer column are provided with threaded grooves. The claw hammer body and the round-headed hammer body are provided with mounting threaded protrusions, which are fixed inside the threaded grooves by threaded engagement. The structure of this hammer is generally consistent with common hammers, making it difficult to improve hammering efficiency during use. Moreover, the hammer shaft is short, making it inconvenient for personnel to hold and apply force with both hands. Summary of the Invention

[0005] To improve the above situation, the present invention provides an inertial hammer that, after striking a nail once with an impact hammer block, uses the inertial force of the falling inertial block to strike the nail a second time, while the hinged structure of the split hammer rod allows the worker to hold the hammer with both hands to apply force.

The nail-starting horn is placed on one end of the hammer head, which has a hollow internal structure forming a sliding cavity. The sliding cavity is cylindrical, and the inertial block is placed inside the sliding cavity and fits against the inner wall of the hammer head. The inertial block is cylindrical. Four venting grooves are formed on the hammer head, equidistantly distributed along the circumference of the sliding cavity and connected to its interior. A clearance groove is formed on the other end of the hammer head, and one end of the impact hammer block passes through… The clearance groove extends into the interior of the sliding cavity. The other end of the impact hammer block is located outside the sliding cavity, and its diameter is larger than that of one end of the impact hammer block. The impact plate is placed inside the sliding cavity and is fixedly connected to one end of the impact hammer block. The energy-absorbing block is placed on the impact plate and is located between the inertial block and the impact plate. The energy-absorbing block and the impact plate are fixedly connected. Two fixed plates are placed on the outer wall of the hammer head and are located at both ends of the hammer head. One end of each of the two split hammer rods is hinged between the two fixed plates through a connecting shaft and is located on both sides of the hammer head. The two split hammer rods are in contact with each other. The shock-absorbing sleeve is placed on the other end of the two split hammer rods. A friction pad is fitted on the split hammer rod. The energy-absorbing block is made of magnetic material.

[0007] Furthermore, the inertial block has a spherical structure, and the top center of the energy-absorbing block has an energy-absorbing groove corresponding to the inertial block, and the top edge of the energy-absorbing block arches towards the inertial block.

[0008] Beneficial effects.

[0009] First, it can utilize the inertial force generated by the hammering action to create a secondary inertial hammering action in a single hammering action, thereby improving the hammering efficiency.

[0017] The components are: a nail-starting horn (1), a connecting shaft (2), a fixing plate (3), a split hammer rod (4), a shock-absorbing sleeve (5), an impact hammer block (6), an impact plate (7), an energy-absorbing block (8), an inertial block (9), a ventilation groove (10), a sliding cavity (11), a hammer head (12), and an energy-absorbing groove (13). Detailed Implementation

[0018] Example 1

[0019] The inertial hammer of the present invention is implemented as follows: The inertial hammer of the present invention is composed of a nail-starting horn (1), a connecting shaft (2), a fixing plate (3), a split hammer rod (4), a shock-absorbing sleeve (5), an impact hammer block (6), an impact plate (7), an energy-absorbing block (8), an inertial block (9), a ventilation groove (10), a sliding cavity (11), a hammer head (12), and an energy-absorbing groove (13). The nail-starting horn (1) is placed on one end of the hammer head (12), and the hammer head (12) is hollow inside. The structure includes a sliding cavity (11) formed inside, which is cylindrical. An inertial block (9) is placed inside the sliding cavity (11) and fits against the inner wall of the hammer head (12). The inertial block (9) is cylindrical. The hammer head (12) has four ventilation slots (10) that are equidistantly distributed along the circumference of the sliding cavity (11) and connected to the interior of the sliding cavity (11). A clearance slot is provided at the other end of the hammer head (12). One end of the impact hammer block (6) extends through the relief groove into the interior of the sliding cavity (11), and the other end of the impact hammer block (6) is located outside the sliding cavity (11) with a diameter larger than that of one end of the impact hammer block (6). The impact plate (7) is placed inside the sliding cavity (11) and is fixedly connected to one end of the impact hammer block (6). The energy-absorbing block (8) is placed on the impact plate (7) and is located between the inertial block (9) and the impact plate (7). The energy-absorbing block (8) and the impact plate (7) are fixedly connected. The two fixed plates (3) are placed on the outer wall of the hammer head (12) and are located at both ends of the hammer head (12). One end of the two split hammer rods (4) is hinged between the two fixed plates (3) through the connecting shaft (2) and is located on both sides of the hammer head (12). The two split hammer rods (4) are close together. The shock-absorbing sleeve (5) is sleeved on the other end of the two split hammer rods (4). The split hammer rods (4) are fitted with friction pads. The energy-absorbing block (8) is made of magnetic material.

[0020] In use, initially, the two hammer rods (4) are joined together and fitted together through the shock-absorbing sleeve (5). When using an inertial hammer to strike, the operator holds the two fitted hammer rods (4) and raises the hammer head (12) to accumulate force. When the hammer head (12) rises, due to the downward resistance, the inertial block (9) inside the sliding cavity (11) of the hammer head (12) slides to the bottom of the sliding cavity (11). The impact hammer block (6) slides downwards from the hammer head (12) through the guide of the relief groove, and then... The hammer (12) falls rapidly and strikes the nail. During the fall, the hammer (12) experiences upward resistance, causing the inertial block (9) inside the sliding cavity (11) of the hammer (12) to slide to the top of the sliding cavity (11) due to the upward resistance. The impact hammer (6) moves into the sliding cavity (11) due to the upward resistance and the guide of the relief groove. Then, the impact hammer (6) first strikes the nail and performs one strike. At this time, the inertial block inside the sliding cavity (11) of the hammer (12)... (9) Due to the influence of inertial force, it continues to move downward and then strikes the energy-absorbing block (8) on the impact plate (7). The energy-absorbing block (8) and the impact plate (7) transmit the impact force to the impact hammer block (6), thereby hammering the nail with secondary inertial force and improving the hammering efficiency. When the inertial block (9) slides inside the sliding cavity (11), the ventilation groove (10) can regulate the airflow inside the sliding cavity (11) so that the air pressure inside the sliding cavity (11) is always stable. Balance, thereby ensuring the normal sliding of the inertial block (9). When it is necessary to hammer the nail with both hands, remove the shock-absorbing sleeve (5) from the other end of the two hammer rods (4), and then rotate the two hammer rods (4) through the connecting shaft (2) so that the included angle between the two hammer rods (4) gradually increases. Then, hold the two hammer rods (4) with both hands to hammer the nail and apply a greater hammering force. At the same time, the opened hammer rods (4) change the angle between the hammer rod and the hammer head (12) to perform a 90° bending hammering.

[0021] Example 2

[0022] The difference between this embodiment and embodiment 1 is that the inertial block (9) is a spherical structure, and the top center of the energy-absorbing block (8) has an energy-absorbing groove (13) corresponding to the inertial block (9), and the top edge of the energy-absorbing block (8) arches towards the inertial block (9); in use, it can reduce the sliding resistance of the inertial block (9) in the sliding cavity (11), and absorb and transmit the inertial impact force to the impact hammer block (6) through the energy-absorbing groove (13) that matches the inertial block (9);

[0023] The design of the friction pad on the hammer rod (4) can increase the friction between the two hammer rods (4) and prevent the two hammer rods (4) from opening. On the other hand, it can increase the friction between the worker's hand and the hammer rod (4) and prevent the inertial hammer from slipping off.

[0024] The inertial block (9) is designed as a cylindrical block, which can slide in close contact with the cylindrical sliding cavity (11) to avoid the inertial block (9) shifting laterally and causing uneven force on the nail;

[0025] The design of the top edge of the energy-absorbing block (8) arching towards the inertial block (9) can further buffer and guide the spherical inertial block (9), so that the spherical inertial block (9) can accurately fall into the energy-absorbing groove (13) corresponding to the inertial block (9).

[0026] The design of the four ventilation slots (10) being equidistantly distributed along the circumference of the sliding cavity (11) and connected to the interior of the sliding cavity (11) enables the air inside the sliding cavity (11) to circulate evenly, thereby maintaining the inertial block (9) under uniform resistance and avoiding the impact force direction of the nail being deflected due to different resistance in a certain direction of the inertial block (9).

[0027] The energy-absorbing block (8) is designed to be made of magnetic material, which can increase the attraction of the inertial block (9). When the inertial block (9) is hammered a second time, it can quickly attract the inertial block (9) and prevent the inertial block (9) from rebounding upwards due to the impact, thereby maximizing the transmitted inertial force.

[0028] The design of the shock-absorbing sleeve (5) can buffer and unload the vibration force on the hammer rod (4) to avoid injury to the hands of the staff.

[0029] The energy-absorbing block (8) and the inertial block (9) work together to absorb and transfer the impact force of the inertial block (9) being hammered twice due to the downward inertial force. This design can transfer the secondary inertial impact force of the inertial block (9) hitting the energy-absorbing block (8) to the nail at the bottom of the impact hammer block (6). Thus, after the impact hammer block (6) hammers the nail once, the inertial force of the falling inertial block (9) is used to hammer the nail a second time.

[0030] The design of the hammer rod (4) and the connecting shaft (2) cooperating and rotating around the hammer head (12) allows the two hammer rods (4) to be rotated and opened, making it convenient for workers to hold the hammer with both hands. At the same time, the two hammer rods (4) form a 90° bent hammering motion.

[0031] The goal is to achieve the following: after the nail is struck once by the impact hammer block (6), the nail is struck a second time by the inertial force of the falling inertial block (9). At the same time, the hinge structure of the split hammer rod (4) allows the worker to apply force with both hands.
