Description

Technical Field

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

[0002] Geological exploration is a crucial means for humankind to understand the Earth, utilize its resources, and ensure engineering safety. Through geological exploration, natural resources such as minerals and oil and gas can be identified to support their development and utilization; underground geological conditions can be determined to ensure engineering safety; and the laws governing Earth's evolution can be revealed, providing key evidence for resource management, engineering, and scientific research. In field geological exploration operations, the geological hammer is one of the commonly used basic tools. It is mainly used to strike rocks to observe their mineral composition and structure, break rocks to obtain samples, or assist in cleaning and preparing the exploration target area. It is a key tool for geologists to obtain first-hand geological data.

[0003] Existing geological hammers mostly have fixed handle lengths, which cannot be flexibly adjusted according to the user's grip habits or specific exploration scenarios, affecting the effectiveness of the geological hammer. At the same time, the hammerhead and handle of geological hammers are mostly welded or integrally formed, making it difficult to quickly disassemble and replace them. Since different geological exploration tasks have different functional requirements for the hammerhead, the fixed connection structure makes the geological hammer's function singular. Carrying multiple geological hammers with different functions would increase the carrying burden and reduce the convenience of field operations. Therefore, a multi-functional geophysical geological hammer is proposed to solve the above problems. Utility Model Content

Detailed Implementation

[0032] 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.

[0033] Reference Figure 1 , Figure 4 and Figure 5This utility model provides an embodiment of a multifunctional geophysical exploration hammer, comprising an outer handle 1, an inner handle 2 slidably connected inside the outer handle 1, and a length adjustment mechanism installed on the outer side of the outer handle 1. The length adjustment mechanism allows for adjustment of the telescopic length of the inner handle 2, thus adjusting the handle length. A quick-release assembly is installed at the end of the inner handle 2, and a hammer head 5 is installed on the outer side of the quick-release assembly. The quick-release assembly allows for quick disassembly and installation of the hammer head 5, facilitating flexible replacement of different hammer heads 5 to adapt to diverse geological exploration scenarios and saving storage space for easy carrying. The length adjustment mechanism includes a telescopic assembly and a fixing assembly. The telescopic assembly includes a rotating head 3, which is rotatably connected to the end of the outer handle 1. A threaded rod 4 is fixedly connected to the outer side of the rotating head 3, and the threaded rod 4 is threadedly connected to the inside of the inner handle 2. The fixing assembly includes a support 13, which is fixedly connected to the outer side of the outer handle 1. A round shaft 15 is rotatably connected to the middle of the support 13. A torsion spring 16 is fitted around the outer circumference of the shaft 15. A pressure plate 18 is rotatably connected to the outer side of the shaft 15. A plug rod 19 is slidably connected to the middle of the support 13. The pressure plate 18 is located in the middle of the plug rod 19, and the plug rod 19 is engaged with the rotating head 3. Multiple insertion holes 14 are opened on the outer side of the rotating head 3. The plug rod 19 is engaged inside the insertion holes 14. The elastic force of the torsion spring 16 will push up the tail end of the pressure plate 18, thereby pressing down the head end of the pressure plate 18, so that the plug rod 19 is engaged with the rotating head 3. The plug is inserted into the socket 14 to lock the rotating head 3 and prevent it from rotating, thereby fixing the length of the geological hammer handle. Press the end of the pressure plate 18 to lift its head, which will drive the plug rod 19 out of the socket 14 to release the locking. Then rotate the rotating head 3 to drive the threaded rod 4 to rotate. The threaded rod 4 will then drive the inner handle 2 to slide along the outer handle 1, thereby adjusting the extension length of the inner handle 2. After adjustment, the plug rod 19 is re-locked into the socket 14 to fix the length of the geological hammer handle.

[0034] Reference Figures 1-3 The quick-release assembly includes a snap-fit ​​connector 8, which is fixedly connected to the end of the inner handle 2. A snap-fit ​​connector 10 is fixedly connected to the outer side of the hammer head 5. Snap-fit ​​connectors 8 and 10 snap together. A threaded tube 11 is fixedly connected to the outer side of the hammer head 5. A threaded sleeve 9 is threadedly connected to the outer side of the threaded tube 11. The threaded sleeve 9 is located on the outer periphery of the inner handle 2. Multiple clamping blocks 12 are fixedly connected to the end of the threaded tube 11. First, snap-fit ​​connector 8 and snap-fit ​​connector 10 are engaged to align the inner handle 2 with the hammer head 5 and prevent the hammer head 5 from rotating. Then, the threaded sleeve 9 is tightened onto the outer periphery of the threaded tube 11 through the thread. While tightening, the threaded sleeve 9 will squeeze the clamping blocks 12 to press the inner handle 2. Through the tightening of the thread and the clamping action of the clamping blocks 12, the inner handle 2 and the hammer head 5 are firmly fixed, thereby achieving quick disassembly and assembly of the hammer head 5 while maintaining the stability of the hammer head 5 installation.

[0035] Reference Figure 1 , Figure 4 and Figure 5One end of the torsion spring 16 contacts the support 13, and the other end of the torsion spring 16 contacts the pressure plate 18. The two ends of the torsion spring 16 abut against the tail ends of the support 13 and the pressure plate 18, respectively, so that the head end of the pressure plate 18 presses down to keep the insertion rod 19 and the insertion hole 14 locked together. Multiple locking strips 6 are fixedly connected to the outer side of the inner handle 2. Multiple locking strips 6 are slidably connected to the inner side of the outer handle 1. Multiple locking grooves 7 are opened on the inner side of the outer handle 1. Multiple locking strips 6 are slidably connected to the inside of multiple locking grooves 7. The inner handle 2 slides in the outer handle 1 through the locking strips 6 and locking grooves 7 to prevent the inner handle 2 from rotating. A slot 17 is opened in the middle of the support 13. The insertion rod 19 is slidably connected to the inside of the slot 17.

[0036] Working principle: The rotating head 3 drives the threaded rod 4 to rotate synchronously. Since the retaining strip 6 on the outer side of the inner handle 2 slides along the retaining groove 7 on the inner side of the outer handle 1, it restricts the rotation of the inner handle 2. Therefore, when the threaded rod 4 rotates, it drives the inner handle 2 to extend and retract along the axial direction of the outer handle 1, thereby adjusting the handle length. The two ends of the torsion spring 16 abut against the support 13 and the tail end of the pressure plate 18 respectively. Its elasticity causes the head end of the pressure plate 18 to press down, so that the insertion rod 19 is engaged in the insertion hole 14, thereby locking the rotating head 3 to fix the handle length. Pressing the tail end of the pressure plate 18 causes its head end to lift up, driving the insertion rod 19 to disengage from the insertion hole 14, thereby releasing the engagement and rotating the rotating head 3 to adjust the length. After the adjustment is completed, the insertion rod 19 is re-engaged into the insertion hole 14 to fix the handle length.

[0037] The locking connector 8 at the end of the inner handle 2 engages with the locking connector 10 on the outside of the hammer head 5, restricting the rotation of the hammer head 5. Then, the threaded sleeve 9 is tightened along the threaded tube 11 on the outside of the hammer head 5. During the tightening process, the threaded sleeve 9 squeezes multiple clamping blocks 12 at the end of the threaded tube 11, causing the clamping blocks 12 to press against the inner handle 2. Through the threaded locking and the squeezing action of the clamping blocks 12, the inner handle 2 and the hammer head 5 are firmly fixed. By rotating the threaded sleeve 9 in the opposite direction, the squeezing of the clamping blocks 12 can be released, thereby realizing the quick assembly and disassembly of the hammer head 5. This facilitates the replacement of different hammer heads 5 to adapt to various exploration scenarios and improves the portability of the geological hammer.

[0038] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
