DETAILED DESCRIPTION
[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.
[0022] In this embodiment, Figure 1 As shown, it includes a hammer handle 1, which is made of metal, usually iron. The hammer handle 1 is provided with a first shock-absorbing layer 2, the first shock-absorbing layer 2 is provided with a hard layer 3, and the hard layer 3 is provided with a second shock-absorbing layer 4. The first shock-absorbing layer 2 and the second shock-absorbing layer 4 are both made of soft rubber material, and the hard layer 3 is made of hard plastic material. The soft first shock-absorbing layer 2 achieves shock absorption and shock reduction effects from the innermost layer, and the hard layer 3 of hard plastic is the hardest layer to ensure the overall strength of the handle, and the second shock-absorbing layer 4 as the outermost layer is also made of soft material, which can not only perform secondary shock reduction but also ensure the gripping feel.
[0023] Preferably, the first shock-absorbing layer 2 is made of a silicone-like material. As a composite material, silicone-like material can achieve shock absorption, high temperature resistance, corrosion resistance and other effects, and it can achieve different degrees of effect according to different formula ratios, so it can be flexibly adjusted according to different needs.
[0024] Preferably, the hard layer 3 is most often made of PP.
[0025] Preferably, the second shock-absorbing layer 4 is made of thermoplastic rubber, such as TPR.
[0026] The first shock-absorbing layer 2 is provided with a through hole 7 for the hammer handle 1 to penetrate along the length direction of the handle hammer, so that the first shock-absorbing layer 2 can be firmly sleeved on the hammer handle 1 to form a tight fit. It should be noted that the length dimension of the first shock-absorbing layer 2 is smaller than the length dimension of the hammer handle 1, that is, the first shock-absorbing layer 2 does not cover the entire hammer handle 1, that is, the two ends of the hammer handle 1 are still not covered by the first shock-absorbing layer 2. The purpose of such a design is to make the connection between the first shock-absorbing layer 2 and the hammer handle 1 more firmly, and it is not easy to separate from each other along the axial direction of the hammer handle 1. The uncovered two ends of the hammer handle 1 are used to fit with the hard layer 3, so that the wrapping layer of the entire hammer handle 1 is more fitted and stable.
[0027] In this embodiment, a cavity 8 is opened in the hard layer 3, and the opening of the cavity 8 is set at the end of the hard layer 3 facing the hammer head 5, that is, the top opening of the hard layer 3, and the bottom end is a bottom sealing structure. The hammer handle 1 together with the first shock-absorbing layer 2 is inserted into the cavity 8 from the opening to form a tight fit.
[0028] A hammer head 5 which is integrated with the hammer handle 1 is provided at the top of the hammer handle 1. The hammer handle 1 is a strip-shaped flat plate-like structure made of metal. The end of the hammer handle 1 away from the hammer head 5 is rounded to facilitate the insertion of the hammer handle 1 into the first shock-absorbing layer 2 and the hard layer 3.
[0029] The handle of the hammer handle 1 is provided with hollow holes 6 at both ends thereof. The hollow holes 6 serve as shock-absorbing holes, which not only play a certain shock-absorbing role, but also reduce the weight of the hammer handle 1. A first protrusion 13 extends from the inner wall of the through hole 7 of the first shock-absorbing layer 2, and a second protrusion 14 extends from the inner wall of the cavity 8. When the first shock-absorbing layer 2 is located in the cavity 8 of the hard layer 3, the first protrusion 13 and the second protrusion 14 are axially spliced side by side to form a complete protrusion. The shape of the complete protrusion is the same as the hollow hole 6, and can be just embedded in the hollow hole 6 to form an adaptation with the hollow hole 6. In this embodiment, the two hollow holes 6 are respectively located at the top and the bottom of the hammer handle 1. The first protrusion 13 has two parts. One part is located at the top and is spliced with the second protrusion 14 to form a complete protrusion embedded in the hollow hole 6 at the top, and the other part is located at the bottom and is a separate complete protrusion shape and is directly embedded in the hollow hole 6 at the bottom, so that an axial limit is formed between the first shock-absorbing layer 2, the hard layer 3 and the hammer handle 1.
[0030] A transition section 9 is provided between the hammer head 5 and the hammer handle 1. The transition section 9, the hammer head 5 and the hammer handle 1 are all of an integrated design to ensure the strength of the entire shock-absorbing hammer. The top of the transition section 9 is connected to the hammer head 5, and the bottom of the transition section 9 is connected to the hammer handle 1. The outer diameter of the transition section 9 is larger than the outer diameter of the hammer handle 1, so that the end of the hard layer 3 facing the hammer head 5 fits into the bottom end face of the transition section 9. Finally, the transition section 9 and the hard layer 3 have a smooth transition, which not only makes the appearance more beautiful, but also makes the hard layer 3 more stable and firm.
[0031] The second shock-absorbing layer 4 is opened at both ends and is sleeved on the outside of the hard layer 3. The outer peripheries of the two end portions of the hard layer 3 are provided with integrated outward-turned portions 10. The two ends of the second shock-absorbing layer 4 are respectively fitted with the corresponding outward-turned portions 10, and a smooth transition is formed between the two ends of the second shock-absorbing layer 4 and the corresponding outward-turned portions 10. Furthermore, first step surfaces 11 are formed on the opposite surfaces of the two outward-turned portions 10, and second step surfaces 12 are provided on the end surfaces of the two ends of the second shock-absorbing layer 4. When the second shock-absorbing layer 4 is sleeved on the hard layer 3, the first step surface 11 and the second step surface 12 are matched and fitted with each other, so that a radial limit is formed between the second shock-absorbing layer 4 and the hard layer 3 to prevent the second shock-absorbing layer 4 from rotating radially along the hard layer 3.
[0032] It should be noted that from Figure 3 It can be seen that the through holes of the first shock-absorbing layer 2 form two hole structures at the top, and the bottom end of the hammer handle 1 is a sealed structure. During the production process, the hammer handle 1 is fixed in a mold, and the mold has a mold cavity adapted to the hammer handle 1. Then, a silicone-like material is poured into the mold cavity. When the silicone-like material is cooled, the first shock-absorbing layer 2 covering the outside of the hammer handle 1 is generated.
[0033] The second shock-absorbing layer 4 is subjected to anti-skid treatment on the outside, and an anti-skid texture may be provided on the surface.
[0034] The present utility model is not limited to the above-mentioned optimal implementation mode. Anyone can derive other various forms of products under the inspiration of the present utility model. However, no matter what changes are made in the shape or structure, all those having the same or similar technical solutions as the present application fall within the protection scope of the present utility model.
