Description

Technical Field

[0001] This utility model relates to the field of rubber mallets, and more specifically, to a split-type rubber mallet. Background Technology

[0002] When laying floor tiles or wall tiles on a construction site, a rubber mallet is needed to flatten the tiles or to compact or secure fragile building materials; a steel hammer is also needed during construction to break and repair building materials. Rubber mallets and steel hammers are frequently used on construction sites.

[0003] A rubber mallet, consisting of a hammerhead and a handle, is a special type of hammer. Its main characteristic is that the hammerhead is made of rubber, which provides elasticity and cushions the impact when striking objects, making it particularly suitable for striking fragile items or situations requiring gentle tapping. In existing rubber mallet designs, some have a one-piece design to prevent the hammerhead from loosening or detaching during use. This requires replacement of the entire mallet if damaged, leading to higher operating costs. Furthermore, one-piece rubber mallets, due to their longer handles, take up more space and are inconvenient to carry. Separate designs allow for easier carrying and storage; the hammerhead and handle are simply assembled before use. However, there is a risk of the hammerhead loosening or even detaching from the handle during use, which not only affects the tool's proper function but may also pose a safety hazard.

[0004] Therefore, there is a need for a split-type rubber mallet that can maintain the stability of the connection between the hammer head and the hammer handle, facilitate replacement when the hammer head is damaged to reduce usage costs, and is easy to carry. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a split rubber hammer.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A split-type rubber mallet includes a hammer head and a hammer handle. The hammer head has a trapezoidal cross-section and a connecting sleeve is snapped onto it. The hammer head is equipped with a fixing chain and has a positioning hole that mates with the fixing chain. The hammer handle is detachably connected to the connecting sleeve and the hammer head. Two threaded rods are installed on the connecting sleeve, which are respectively placed on both sides of the hammer head. The fixing chain passes through the positioning hole and is movably connected to it. Each end of the fixing chain is movably connected to a first threaded tube. The two first threaded tubes are threadedly connected to the two threaded rods respectively. The outer diameter of the first threaded tube is smaller than the diameter of the positioning hole.

[0008] A further configuration is provided, wherein a second threaded tube is respectively inserted on both sides of the connecting sleeve, the two second threaded tubes are placed on both sides of the hammer head, the hammer head has a connecting hole corresponding to the two second threaded tubes, the hammer handle passes through one second threaded tube, the connecting hole and the other second threaded tube in sequence, and the hammer handle is threadedly connected to the two second threaded tubes, and the hammer handle moves in the connecting hole.

[0009] Further configured, one end of the first threaded tube is closed, and a rotating hole is opened at one end of the first threaded tube. A shaft that is rotatably connected to the rotating hole is installed on the fixed chain. A retaining plate is provided inside the first threaded tube. The shaft passes through the rotating hole, extends into the first threaded tube, and is fixedly connected to the retaining plate. The diameter of the retaining plate is larger than the diameter of the rotating hole.

[0010] A further feature is provided that the hammer handle is equipped with an anti-slip part, which is integrally formed with the hammer handle.

[0011] By adopting the above technical solution, the beneficial effects of this utility model are: it can maintain the stability of the connection between the hammer head and the hammer handle, while also facilitating replacement when the hammer head is damaged, reducing usage costs, and making it easy to carry and improving practicality.

[0016] Reference Figures 1 to 3 The embodiments of this utility model will be further described below.

[0017] A split-type rubber mallet includes a hammer head 100 and a hammer handle 200. The hammer head 100 has a trapezoidal cross-section and a connecting sleeve 1 is snapped onto it. A fixing chain 2 is provided on the hammer head 100, and a positioning hole 4 is formed on the hammer head 100 to mate with the fixing chain 2. The hammer handle 200 is detachably connected to the connecting sleeve 1 and the hammer head 100. Two threaded rods 3 are respectively installed on the connecting sleeve 1 and positioned on both sides of the hammer head 100. The fixing chain 2 passes through the positioning hole 4 and is movably connected to the positioning hole 4, and a first thread is movably connected to each end of the fixing chain 2. The tube 5, two first threaded tubes 5 are respectively threaded to two threaded rods 3. The outer diameter of the first threaded tube 5 is smaller than the diameter of the positioning hole 4. A second threaded tube 6 is passed through each side of the connecting sleeve 1. The two second threaded tubes 6 are placed on both sides of the hammer head 100. The hammer head 100 has a connecting hole 7 corresponding to the two second threaded tubes 6. The hammer handle 200 passes through one second threaded tube 6, the connecting hole 7 and the other second threaded tube 6 in sequence. The hammer handle 200 is threaded to the two second threaded tubes 6. The hammer handle 200 moves in the connecting hole 7.

[0018] The connecting sleeve 1 is snapped onto the hammer head 100. The hammer handle 200 passes through one second threaded tube 6, the connecting hole 7, and another second threaded tube 6 in sequence, and the hammer handle 200 is threadedly connected to the two second threaded tubes 6. This fixes the hammer handle 200 to the hammer head 100 and the connecting sleeve 1, and also makes it easy to disassemble the hammer handle 200, reducing space occupation, making the rubber mallet easy to carry, and improving its practicality. The fixing chain 2 passes through the positioning hole 4, and the two first threaded tubes 5 are rotated so that the two first threaded tubes 5 are respectively threadedly connected to the two threaded rods 3. At this time, the fixing chain 2 is in a tight position. The hammer is held in a taut state, which further connects and fixes the hammer head 100 to the connecting sleeve 1 via the fixed chain 2, thereby strengthening the connection stability of the hammer handle 200 and the overall structure of the hammer head 100. When the hammer head 100 is used to strike an object, the worker holds the hammer handle 200 and the hammer head 100 strikes the object. At this time, the hammer head 100 is subjected to an upward force. In combination with the trapezoidal cross-section of the hammer head 100, as the hammer head 100 continues to strike the object, the hammer head 100 and the connecting sleeve 1 are locked tighter and tighter, further strengthening the connection stability of the overall structure of the hammer head 100 and the hammer handle 200.

[0019] When hammer head 100 is damaged and needs to be replaced, rotate hammer handle 200 to disengage it from the second threaded tube 6 and disengage it from the connecting hole 7. Then, rotate the first threaded tube 5 to disengage it from the threaded rod 3, thereby disengaging the fixing chain 2 from the positioning hole 4. This makes it easy to remove the fixing chain 2 from the hammer head 100. Then, strike the hammer head 100 downwards to disengage it from the connecting sleeve 1. This makes it easy to disassemble and replace the damaged hammer head 100. This method maintains the stability of the connection between the hammer head 100 and the hammer handle 200 while facilitating replacement when the hammer head 100 is damaged, thus reducing the cost of use.

[0020] One end of the first threaded tube 5 is closed, and a rotating hole 8 is opened at one end of the first threaded tube 5. A shaft 9 that is rotatably connected to the rotating hole 8 is installed on the fixed chain 2. A clamping plate 10 is provided inside the first threaded tube 5. The shaft 9 passes through the rotating hole 8 and extends into the first threaded tube 5 and is fixedly connected to the clamping plate 10. The diameter of the clamping plate 10 is larger than the diameter of the rotating hole 8.

[0021] When the first threaded tube 5 is rotated to connect with the corresponding threaded rod 3, the first threaded tube 5 rotates around the corresponding shaft 9. The diameter of the clamping plate 10 is larger than the diameter of the rotating hole 8 so that the first threaded tube 5 will not detach from the shaft 9 during rotation, thus realizing the rotation of the first threaded tube 5 on the fixed chain 2, which facilitates the threaded connection between the first threaded tube 5 and the threaded rod 3.

[0022] An anti-slip part 300 is installed on the hammer handle 200 to increase the friction between the hammer handle 200 and the worker's palm, and to prevent the hammer handle 200 from falling out of the worker's hand, which could cause safety hazards. The anti-slip part 300 is integrally formed with the hammer handle 200, which enhances the structural stability of the anti-slip part 300 and the hammer handle 200.

[0023] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any ordinary changes and substitutions made by those skilled in the art within the scope of the technical solution of the present utility model should be included within the protection scope of the present utility model.
