Description

Technical Field

[0001] This utility model relates to the field of geological exploration technology, and in particular to a foldable geological hammer. Background Technology

[0002] The geological hammer is one of the core tools in geological exploration. Made of high-quality steel, its design varies depending on the rock properties of the work area. One end of the hammer head is rectangular or square, while the other end is pointed or wedge-shaped. In use, the square end is generally used to strike the rock, breaking it into pieces; the pointed or wedge-shaped end is used to strike along the bedding planes, allowing for strata stripping, which is beneficial for finding fossils and sampling. It is widely used in rock sampling, stratigraphic analysis, and mineral exploration.

[0003] Most existing geological hammers adopt an integrated structure, with the hammer head and hammer handle fixed by simple riveting or welding. This not only takes up a lot of space during transportation and storage, but also means that the entire tool will be scrapped once the hammer head or hammer handle is damaged, resulting in high maintenance costs.

[0004] Therefore, those skilled in the art have provided a foldable geological hammer to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a foldable geological hammer. The foldable design greatly reduces the size of the geological hammer when it is not in use. The hammer head can be removed from the connecting block, and the hammer handle can also be folded up for easy placement in a backpack or tool bag, saving space and making it convenient for geological surveyors to carry. It is especially suitable for long-term, long-distance work scenarios in the field.

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

[0007] A foldable geological hammer includes a hammer head and a connecting block. The connecting block has a fixing mechanism inside. The fixing mechanism includes a turntable. The upper end of the turntable has multiple inclined grooves. Each of the multiple inclined grooves has a locking block slidably disposed at its upper end.

[0008] The lower end of the connecting block is fixedly provided with a second hammer handle, and a first hammer handle is rotatably provided on one side of the second hammer handle. A fixing ring is threadedly connected to the outside of the second hammer handle.

[0009] Furthermore, springs are fixedly installed on opposite sides of each pair of the multiple card blocks, and springs are fixedly installed inside the connecting block on opposite sides of each pair of the multiple springs.

[0010] Furthermore, the lower outer end of the turntable is rotatably disposed inside the connecting block.

[0011] Furthermore, the exterior of each of the card blocks is slidably disposed inside the connecting block.

[0012] Furthermore, the lower end of the outer surface of the hammer head is provided with multiple slots, and the multiple locking blocks are respectively arranged on opposite sides of the multiple slots.

[0013] Furthermore, the fixing ring is externally sleeved on the outside of the second hammer handle and the first hammer handle.

[0014] Furthermore, the lower end of the outer surface of the hammer head is located inside the upper end of the connecting block.

[0015] This utility model has the following beneficial effects:

[0016] 1. The present invention proposes a foldable geological hammer. When it is necessary to connect the geological hammer to the connecting block, the hammer head is inserted into the interior of the connecting block. The insertion of the hammer head will squeeze the locking block, causing the locking block to slide in the opposite direction. When the hammer head is inserted into the appropriate position, the spring pushes the locking block to slide in opposite directions, so that it is embedded in the locking groove, thus fixing the hammer head firmly on the connecting block. The process of installing and removing the hammer head is simple and quick, without the need for additional complicated tools, saving the user's time and energy, improving work efficiency, and also making it easy to replace the hammer head, reducing the cost of use.

[0017] 2. The foldable geological hammer proposed in this utility model allows for the following operation: When using the geological hammer, rotating the fixing ring disconnects the connection between the first and second hammer handles. Then, rotating the first hammer handle unfolds it. Next, the fixing ring is fitted onto the connection between the first and second hammer handles, and then rotated to thread it onto the second hammer handle. The fixing ring then tightly secures the second and first hammer handles, ensuring that the hammer handles do not rotate arbitrarily during use, thus guaranteeing operational stability and safety. Furthermore, the unfolding and folding operation of the hammer handles is not only convenient but also reduces the space occupied by the geological hammer during storage, alleviating the burden of carrying it.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figures 1-5 One embodiment provided by this utility model:

[0027] A foldable geological hammer includes a hammer head 1 and a connecting block 2. The connecting block 2 is provided with a fixing mechanism 3. The fixing mechanism 3 includes a turntable 302. The upper end of the turntable 302 is provided with multiple inclined grooves 303. The upper end of each of the multiple inclined grooves 303 is slidably provided with a locking block 301.

[0028] Multiple locking blocks 301 are fixedly provided with springs 304 on opposite sides of each pair, and multiple springs 304 are fixedly provided inside the connecting block 2 on opposite sides of each pair. The lower outer end of the turntable 302 is rotatably provided inside the connecting block 2. The outer sides of multiple locking blocks 301 are slidably provided inside the connecting block 2. Multiple slots 305 are opened on the lower outer surface of the hammer head 1, and multiple locking blocks 301 are respectively provided on opposite sides of multiple slots 305 on opposite sides of each pair.

[0029] Specifically, when the hammer head 1 is inserted into the connecting block 2, due to the inclined slope design of the upper end of the locking block 301, the slope is subjected to force during the insertion of the hammer head 1, causing the locking block 301 to slide in the opposite direction along the inclined groove 303, simultaneously compressing the spring 304 connected to it, causing the turntable 302 to rotate in linkage within the connecting block 2. When the hammer head 1 reaches the preset position, the spring 304 releases the accumulated elastic potential energy, driving the locking block 301 to slide quickly toward the center of the turntable 302. The opposite side of the locking block 301 is precisely embedded into the hammer head 1 locking groove 305, thereby ensuring that the hammer head 1 is firmly connected, providing solid support for geological exploration operations, and can firmly fix the hammer head 1 on the connecting block 2. In the striking operations of geological exploration, even when facing a large impact force, the hammer head 1 will not easily loosen or fall off, ensuring the safety and stability of use, and improving the reliability and durability of the geological hammer.

[0030] If the hammer head 1 needs to be replaced or maintained, simply rotate the turntable 302 manually. The inclined groove 303 structure drives the locking block 301 to move in the opposite direction along the groove, continuously compressing the spring 304. As the locking block 301 gradually disengages from the locking groove 305, the hammer head 1 loses its constraint and can be easily removed from the connecting block 2, realizing quick maintenance and component replacement, and reducing the cost of use.

[0031] The connection process between hammer head 1 and connecting block 2 can be completed quickly without the aid of tools, improving the efficiency of field operations. Even when subjected to high-intensity continuous impact, hammer head 1 can maintain a stable connection, eliminating the risk of hammer head 1 falling off. In addition, the modular design of hammer head 1 makes it easier to replace damaged parts without replacing the entire tool, reducing the cost of use and significantly reducing the difficulty of maintenance. Even non-professionals can quickly complete the inspection and maintenance, extending the service life of the geological hammer.

[0032] Reference Figures 1-3 The lower end of the connecting block 2 is fixedly provided with a second hammer handle 5, and a first hammer handle 4 is rotatably provided on one side of the second hammer handle 5. A fixing ring 6 is threadedly connected to the outside of the second hammer handle 5.

[0033] The fixing ring 6 is sleeved outside the second hammer handle 5 and the first hammer handle 4, and the lower end of the outer surface of the hammer head 1 is set inside the upper end of the connecting block 2.

[0034] Specifically, before use, rotate the retaining ring 6 to loosen it by unscrewing it downwards along the thread of the second hammer handle 5, and remove it from between the first hammer handle 4 and the second hammer handle 5. This will release the fastening of the retaining ring 6 and the second hammer handle 5. At this time, the first hammer handle 4 can rotate freely around the hinge to unfold it. Then, put the retaining ring 6 on the first hammer handle 4 and the second hammer handle 5, and then connect the retaining ring 6 and the second hammer handle 5 by thread. The retaining ring 6 will firmly clamp the connection between the first hammer handle 4 and the second hammer handle 5, preventing the hammer handle from shaking during use and ensuring accurate and stable operation. When storing, rotate the retaining ring 6 in the opposite direction to unlock it. The first hammer handle 4 can be easily folded and fits snugly against the second hammer handle 5, greatly reducing the overall volume and making it easy to store and carry. The retaining ring 6 can be made of high-strength aluminum alloy and anodized to enhance its surface hardness and corrosion resistance, and extend its service life.

[0035] The double folding design of the hammer head and handle minimizes the size of the geological hammer when stored, making it easy to fit into a backpack side pocket or a dedicated tool bag. It is especially suitable for long-distance field expeditions. The compact storage form reduces space occupation, facilitates transportation and storage, and improves equipment carrying efficiency.

[0036] Working principle: When a geological hammer is needed, first insert the hammer head 1 into the upper part of the connecting block 2. At this time, since the upper part of the locking block 301 has a certain inclination, the insertion of the hammer head 1 will squeeze the locking block 301, causing the locking block 301 to slide in the opposite direction inside the inclined groove 303, and squeeze the spring 304 connected to it, causing it to contract inside the connecting block 2. The sliding of the locking block 301 will cause the turntable 302 to rotate inside the connecting block 2. When the hammer head 1 is inserted to the appropriate position, the locking block 301 slides towards the center of the turntable 302 under the elastic force of the spring 304. When the locking block 301 moves to the final position, its opposite side will be embedded in the locking groove 305, thereby firmly fixing the hammer head 1 on the connecting block 2, which is convenient for the user to carry out the knocking operation of geological exploration.

[0037] When replacing or maintaining hammer head 1, by rotating turntable 302, the inclined groove 303 on turntable 302 will rotate synchronously, thereby causing the upper end of the locking block 301 to slide in opposite directions along the inclined groove 303 inside the connecting block 2, while compressing the spring 304. As the locking block 301 moves upward, the two opposite sides of the locking block 301 gradually exit from the locking groove 305. When the locking block 301 is completely disengaged from the locking groove 305, the hammer head 1 can be removed from the connecting block 2, completing the replacement or maintenance of hammer head 1.

[0038] In use, rotate the retaining ring 6 to move it downwards along the thread of the second hammer handle 5, thus disengaging it from the second hammer handle 5. Then, rotate the first hammer handle 4 on one side of the second hammer handle 5 to unfold it. Next, place the retaining ring 6 on the connection between the first hammer handle 4 and the second hammer handle 5. Then, rotate the retaining ring 6 to make it threadedly connected to the second hammer handle 5. After the connection is completed, the retaining ring 6 will tightly clamp the second hammer handle 5 and the first hammer handle 4, ensuring that the hammer handle will not rotate arbitrarily when using the geological hammer, thus ensuring the stability and safety of the operation. When it is necessary to fold the hammer handle, rotate the retaining ring 6 to loosen its restraint on the second hammer handle 5 and the first hammer handle 4. Then, rotate the first hammer handle 4 around the rotating connection with the second hammer handle 5 to fold it for easy storage and carrying.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
