Description

Technical Field

[0001] This utility model relates to the field of rubber hammers, specifically to a combined rubber hammer. Background Technology

[0002] A rubber mallet is a tool that uses the elasticity of rubber to reduce shock and prevent damage. It is widely used in decoration, furniture installation and other scenarios, and has also led to the development of practical techniques for dealing with neighborhood noise.

[0003] Rubber mallets have a relatively low overall cost, but the parts most prone to damage during use are the ends of the hammer head. As the usage time increases, the ends of the hammer head are easily damaged, affecting subsequent use. In existing technology, the hammer head of a rubber mallet is generally a single piece, and once the ends of the hammer head are damaged, they are discarded and scrapped, while the middle part of the hammer head is still usable. This results in waste, and different users will have different grip positions when using a rubber mallet, while a fixed-length handle can only provide a certain range of grip.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0018] The utility model will now be further described with reference to the accompanying drawings and specific embodiments: Please see Figures 1 to 11 According to an embodiment of this utility model, a combined rubber hammer includes a hammer body 1. A handle 2 is fixedly installed through the middle of the hammer body 1. The length direction of the handle 2 is perpendicular to the length direction of the hammer body 1. A handle sleeve 3 is fitted onto the outer side of the end of the handle 2 away from the hammer body 1. A through hole 4 is opened inside the handle sleeve 3 for the handle 2 to pass through. A mounting bracket 5 is fixedly installed on the outer side of the end of the handle sleeve 3 away from the hammer body 1. A lead screw 6 is concentrically installed inside the through hole 4, and one end of the lead screw 6 passes through the mounting bracket 5 and is rotatably connected to the mounting bracket 5. A threaded hole 10 is opened inside the outer side of the handle 2 away from the hammer body 1, and the outer side of the lead screw 6 away from the mounting bracket 5 is screwed into the threaded hole 10. By rotating the lead screw 6, the position of the lead screw 6 in the threaded hole 10 can be changed, thereby changing the position of the handle sleeve 3 outside the handle 2. This allows the user to change the position of the handle sleeve 3 according to their own habits and the force applied when using the rubber hammer, providing more grip positions.

[0019] An adjusting handle 7 is fixedly installed at the end of the lead screw 6 away from the hammer body 1. The adjusting handle 7 can easily rotate the lead screw 6. Several ventilation holes 8 are opened on the outer wall of the handle sleeve 3. The ventilation holes 8 can prevent the user's palms from sweating when holding the handle sleeve 3.

[0020] A slide bar 9 is integrally formed on the inner wall of the through hole 4, extending along its length. A slide groove 11 is formed on the outer wall of the handle 2, extending along its length. The slide bar 9 is slidably disposed within the slide groove 11. The arrangement of the slide bar 9 and the slide groove 11 can prevent the handle sleeve 3 from rotating outside the handle 2, thus affecting its use.

[0021] A mounting rod 12 is fixedly installed at one end of the handle 2 near the hammer body 1. The mounting rod 12 has an assembly hole 13. The hammer body 1 includes a hammer base 14, with mounting seats 15 fixedly installed at both ends. A hammer head 16 is fixedly installed at the end of the mounting seat 15 away from the hammer base 14. A through hole 17 is provided in the middle of the hammer base 14, perpendicular to its length. The mounting rod 12 passes through the through hole 17. An assembly rod 18, extending along the length of the hammer base 14, also passes through the assembly hole 13. The hammer body 1 is disassembled into the hammer base 14, mounting seats 15, and hammer head 16, allowing for easy disassembly and assembly. This facilitates subsequent modular installation and allows for easy replacement of the hammer head 16. In actual use, if the hammer head 16 is damaged, it can be replaced individually; other undamaged components do not require replacement.

[0022] The hammer base 14 has a groove 19 at its end, and the end of the assembly rod 18 is located in the groove 19. A locking nut 20 is also provided in the groove 19. The locking nut 20 is installed at the end of the assembly rod 18 and is used to position the assembly rod 18 to ensure that the assembly rod 18 stably limits the installation rod 12.

[0023] A protruding plate 21 is integrally formed at the center of the end of the hammer base 14. A connecting hole 22 is formed along the center of the protruding plate 21. A slot 23 is formed in the middle of the end of the mounting base 15 near the hammer base 14. The protruding plate 21 is inserted into the slot 23. A connecting rod 24 is also provided through the mounting base 15, passing through the connecting hole 22. Similarly, the connecting rod 24 is used to lock the connecting hole 22 to ensure a stable assembly between the mounting base 15 and the hammer base 14.

[0024] The outer wall of the mounting base 15 has a receiving groove 25, and the end of the connecting rod 24 is located in the receiving groove 25. The interior of the mounting base 15 has a locking hole 26, the end of which is located in the receiving groove 25. The middle of the locking hole 26 is connected to the slot 23. The connecting rod 24 passes through the locking hole 26. The receiving groove 25 also has a connecting plate 31, and retaining rings 32 are fixedly installed at both ends of the connecting plate 31. The outer wall of the end of the connecting rod 24 has an annular groove 30, and the retaining rings 32 are engaged with the outside of the annular groove 30. The connecting plate 31 and the retaining rings 32 are used to simultaneously fix the ends of the two connecting rods 24, ensuring the stability of the connecting rods 24 in the locking hole 26, and thus ensuring the locking of the connecting rods 24 to the protrusion 21.

[0025] A limiting bolt 27 is also fixedly installed inside the receiving groove 25. The limiting bolt 27 passes through the middle of the connecting plate 31, and a limiting nut 33 is also installed on the outside of the limiting bolt 27. The connecting plate 31 can be fixed in the receiving groove 25 by the limiting nut 33 and the limiting bolt 27.

[0026] The mounting base 15 has a recessed groove 28 at its end away from the hammer base 14. Several insertion holes 29 are formed within the recessed groove 28. Several insertion rods 34 are integrally formed at the end of the hammer head 16 facing the mounting base 15, and these insertion rods 34 are inserted into corresponding insertion holes 29. The hammer head 16 can be inserted into the insertion holes 29 via the insertion rods 34, and the end of the hammer head 16 can also be embedded in the recessed groove 28, facilitating installation. Furthermore, during subsequent use, the force applied to the hammer head 16 is transmitted to the insertion rods 34, ensuring the stability of the insertion rods 34 within the insertion holes 29.

[0027] Through the above-mentioned solution of this utility model, the structure of this utility model is simple and reasonable, and it is quick and convenient to use and assemble. The design of the handle sleeve 3 can be adjusted on the outside of the handle bar 2 according to the needs, which can provide users with more hand-holding position options. The hammer body 1 is divided into hammer base 14, mounting base 15 and hammer head 16. The hammer head 16, which is most easily damaged, can be quickly replaced after it is damaged. The hammer base 14 and the handle bar 2 can also be quickly replaced and assembled. Each part can be replaced individually, saving the cost of replacement.
