Description

Technical Field

[0001] The present invention relates to the technical field of a percussion tool, and more particularly to a shock-absorbing percussion tool that can reduce the vibration feeling during use. Background Art

[0002] Generally, a hammer usually consists of a metal striking piece and a handle. The striking piece is the part used to strike an object, while the handle is the part used to hold and control the hammer.

[0003] When using a hammer, the impact of the striking piece on the object generates vibrations, which are transmitted to the handle and then affect the user. The reason is that the handle of the current hammer lacks an effective shock-absorbing design, resulting in the direct transmission of vibrations to the user's hand, causing fatigue and discomfort, thereby limiting the efficiency of the user during long-term operations and possibly leading to hand discomfort or pain after long-term use. Summary of the Invention

[0004] To solve the above problems, the present invention provides a shock-absorbing percussion tool. By generating a gap like an air chamber between the shock-absorbing structure and the spacer, it helps to reduce the impact of handle vibrations, reduce its oscillations, and effectively achieve the shock-absorbing effect.

[0005] An embodiment of the present invention provides a shock-absorbing percussion tool, which includes: a striking piece; a handle connected to the striking piece, with a shock-absorbing structure provided on one side surface of the handle, and the outer peripheral edge of the handle is non-planar due to the shock-absorbing structure; a spacer detachably connected to the handle and corresponding to the shock-absorbing structure, with a gap between the spacer and the shock-absorbing structure; and a handle sleeve sleeved on the handle and the spacer, and the handle sleeve is closely attached to the spacer.

[0006] In another embodiment of the present invention, the shock-absorbing structure and the handle are integrally formed.

[0007] In another embodiment of the present invention, the handle is generally rectangular parallelepiped-shaped, the handle has two first side surfaces and two second side surfaces, the width of each first side surface is less than the width of each second side surface, and the shock-absorbing structure is provided on one of the first side surfaces or both first side surfaces.

[0008] In another embodiment of the present invention, the shock-absorbing structure has a plurality of convex portions and a plurality of concave portions arranged at intervals continuously.

[0009] In another embodiment of the present invention, the depth of depression of each concave portion accounts for at least one-tenth of the width of each second side surface.

[0010] In another embodiment of the present invention, the cross-section of each convex portion and each concave portion is one of a rectangular shape, a triangular shape, a trapezoidal shape, or an arc shape.

[0011] In another embodiment of the present invention, the shock-absorbing structure accounts for at least one-third of the length of the handle.

[0012] In another embodiment of the present invention, the spacer has a first part and a second part. The first part is provided with a positioning block that is snap-fitted with the handle, and the second part is sleeved on the handle.

[0013] In another embodiment of the present invention, the shock-absorbing structure further has a notch, and the notch is connected to one of the concave parts.

[0014] In another embodiment of the present invention, the notch is inclined, L-shaped or U-shaped.

[0015] In another embodiment of the present invention, the second part is convexly provided with an abutting block, and the abutting block abuts against the notch.

[0016] In another embodiment of the present invention, the handle has a first end and a second end that are oppositely arranged. The striking member is connected to the first end of the handle; the handle sleeve is sleeved from the second end of the handle.

[0017] In another embodiment of the present invention, the handle is provided with a first through hole near the second end, and a first fixing pin is inserted between the handle sleeve and the first through hole of the handle.

[0018] In another embodiment of the present invention, the handle is provided with a second through hole. The second through hole is arranged on one side of the first through hole close to the first end and adjacent to the shock-absorbing structure; the positioning block of the spacer is snap-fitted with the second through hole.

[0019] In another embodiment of the present invention, the handle is provided with a third through hole. The third through hole is arranged on one side of the second through hole far from the second end and adjacent to the first end, and a second fixing pin is inserted between the striking member and the third through hole of the handle.

[0020] In another embodiment of the present invention, the striking member and the handle are integrally formed.

[0021] Through the above, when the present invention uses the striking member to strike an object, the vibration generated by the handle can generate a gap like an air chamber between the shock-absorbing structure and the spacer. The air in this gap can generate elasticity, which helps to reduce the impact of the handle vibration, reduce its oscillation, and effectively achieve the shock-absorbing effect; thereby, effectively improving the problem that the existing hammer cannot effectively reduce the vibration.

[0061] Please refer to Figures 1 to 10 As shown, the present invention provides a shock-absorbing knocking tool, including:

[0062] A knocking member 10 having an acting portion 11. Please refer to Figure 2 As shown, in the embodiment of the present invention, the acting portion 11 has a knocking area and a nail-pulling area. The knocking area is used for knocking objects, and the nail-pulling area is used for pulling out nails. However, the present invention does not limit the type of the knocking member 10 in this way. The acting portion 11 may also have knocking areas at both ends. The knocking area may be in the shape of a round surface of a general hammer (such as a claw hammer, a double-headed hammer, and a round-headed hammer, etc.), or in the shape of a blade of an axe.

[0063] Please refer to Figures 1 to 3 As shown, in the embodiment of the present invention, when the knocking member 10 and the handle 20 are in two parts, the knocking member 10 has a joint portion 12, and a connecting hole 121 is provided through the joint portion 12. Through the connecting hole 121, the knocking member 10 and the handle 20 are connected to each other; please refer to Figure 8 As shown, in the embodiment of the present invention, when the knocking member 10 and the handle 20 are in one part, the knocking member 10 and the handle 20 are integrally formed.

[0064] A handle 20, which is connected to the striking member 10. The handle 20 is generally rectangular parallelepiped in shape. The handle 20 has a first end 21 and a second end 22 which are oppositely arranged, and two first side surfaces 23 and two second side surfaces 24 connected between the first end 21 and the second end 22. As Figure 2 shown, wherein, when the striking member 10 and the handle 20 are in two-piece form, the joint portion 12 of the striking member 10 can socket the first end 21 of the handle 20, and the first end 21 is planar; the width of each first side surface 23 is less than the width of each second side surface 24.

[0065] A shock-absorbing structure 25 is provided on one side surface of the handle 20, and the shock-absorbing structure 25 makes the outer peripheral edge of the handle 20 non-planar; wherein, the shock-absorbing structure 25 can be provided on one of the first side surfaces 23 or both first side surfaces 23. In the first to fifth embodiments of the present invention, the shock-absorbing structure 25 is provided on one of the first side surfaces 23, as Figures 2 to 7 and Figure 9 shown; in the sixth embodiment of the present invention, the shock-absorbing structure 25 can be provided on both first side surfaces 23, as Figure 10 shown.

[0066] Meanwhile, the shock-absorbing structure 25 and the handle 20 are integrally formed. The shock-absorbing structure 25 has a plurality of convex portions 251, a plurality of concave portions 252 and a notch portion 253. The convex portions 251 and the concave portions 252 are arranged at intervals continuously. The notch portion 253 connects the concave portion 252 closest to the second end 22. Among them, the notch portion 253 can be formed from the first side surface 23 to the second end 22, and the notch portion 253 has a turning angle, as Figures 3 to 10 shown. Further, the notch portion 253 can be inclined (as Figures 4 to 7 shown), L-shaped (as Figure 9 shown) or U-shaped (as Figure 10 shown).

[0067] The shock-absorbing structure 25 occupies at least one-third of the length of the handle 20, and the depression depth of each concave portion 252 occupies at least one-tenth of the width of each second side surface 24. Among them, the cross-sections of the convex portions 251 and the concave portions 252 are one of rectangular, triangular, trapezoidal or arc-shaped; please refer to Figure 2 , Figure 4 and Figures 9 to 10 shown. In the first, fifth and sixth embodiments of the present invention, the cross-sections of the convex portions 251 and the concave portions 252 are rectangular; please refer to Figure 5 shown. In the second embodiment of the present invention, the cross-sections of the convex portions 251 and the concave portions 252 are rectangular; please refer to Figure 6 shown. In the third embodiment of the present invention, the cross-sections of the convex portions 251 and the concave portions 252 are trapezoidal; please refer to Figure 7As shown, in the fourth embodiment of the present invention, the cross-sections of the convex portions 251 and the concave portions 252 are arc-shaped.

[0068] In addition, the handle 20 is provided with a first through hole 26 and a second through hole 27. The first through hole 26 is adjacent to the second end 22, and a first fixing pin 30 can be inserted through the first through hole 26 of the handle 20; the second through hole 27 is provided on one side of the first through hole 26 close to the first end 21 and adjacent to the shock absorption structure 25. Among them, please refer to Figures 1 to 3 As shown, when the striking member 10 and the handle 20 are in two parts, the handle 20 is provided with a third through hole 28. The third through hole 28 is provided on one side of the second through hole 27 away from the second end 22 and adjacent to the first end 21. The connecting hole 121 of the striking member 10 can correspond to the third through hole 28 of the handle 20, and a second fixing pin 40 is inserted between the connecting hole 121 and the third through hole 28. The second fixing pin 40 can fix the striking member 10 and the handle 20, as Figures 1 to 3 shown.

[0069] A spacer 50 is detachably connected to the handle 20. The spacer 50 has a first part 51 and a second part 52. A positioning block 511 protrudes from one side surface of the first part 51. The positioning block 511 can be clamped with the second through hole 27 of the handle 20. The second part 52 of the spacer 50 is sleeved on the handle 20; in the embodiment of the present invention, the number of the positioning blocks 511 is two, and the two positioning blocks 511 are symmetrically arranged on one side surface of the first part 51, as Figure 3 shown.

[0070] At the same time, when the spacer 50 is clamped to the handle 20, the first part 51 of the spacer 50 can correspond to contact the shock absorption structure 25. There is a gap S between the spacer 50 and the shock absorption structure 25. The size of this gap S is different due to the distance between the concave portions 252 and the missing portions 253 and the spacer 50; and the gap S is like an air chamber, there is air in the gap S, and the air in the gap S can be ordinary air or compressed air. The air in the gap S has a shock absorption and buffering effect, and the amount of air in the gap S can affect its buffering force. It should be particularly noted that when the air in the gap S is compressed air, it can form like an air spring and can absorb many small rebound vibrations.

[0071] Please refer to Figures 9 to 10 As shown, in the fifth and sixth embodiments of the present invention, when the missing portion 253 is in an L shape or a U shape, the second part 52 protrudes with a abutting block 521. The abutting block 521 abuts against the missing portion 253, so as to connect the handle 20 by abutting with the abutting block 521, so that when the user strikes, the handle 20 can be stably held and the handle 20 can be prevented from being displaced.

[0072] A handle sleeve 60 which can be sleeved on the handle 20 and the spacer 50 from the second end 22 of the handle 20. The handle sleeve 60 is in close fit with the spacer 50. The handle sleeve 60 is provided with an opening 61 therethrough. The handle sleeve 60 is connected to the handle 20, and the opening 61 of the handle sleeve 60 can correspond to the first through hole 26 of the handle 20. A first fixing pin 30 is inserted through the opening 61 and the first through hole 26. The first fixing pin 30 can fix the handle sleeve 60 and the handle 20, as Figure 1 and Figure 2 shown.

[0073] Referring to the table below, it can be seen that when the two types of hammers have similar knocking speeds (about equal to 32), the hammer with the shock-absorbing structure 25 of the present invention has a vibration amplitude reduction of more than 5% compared to the hammer without the shock-absorbing structure 25 of the present invention. Therefore, the present invention indeed has a shock-absorbing effect.

[0074]

[0075]

[0076] Therefore, when the present invention uses the striking member 10 to strike an object, the vibration feeling generated by the handle 20 can pass through the gap S like an air chamber generated between the shock-absorbing structure 25 and the spacer 50. The air in this gap S has a shock-absorbing and buffering effect, which helps to reduce the influence of the vibration of the handle 20 and make its oscillation decrease, effectively achieving the shock-absorbing effect.

[0077] The above embodiments are only used to illustrate the present invention, not to limit the scope of the present invention. All kinds of modifications or changes made without departing from the spirit of the present invention fall within the scope intended to be protected by the present invention.
