Description

Technical Field

[0001] This utility model relates to the field of geological exploration hammer technology, specifically a geological exploration hammer that is easy to fold and use. Background Technology

[0002] A geological hammer is one of the essential tools for geologists to collect specimens. It is mainly used to strike loose and soft rocks to collect fresh rock specimens. As a specially designed tool, the geological hammer has a square head at one end for striking and a wedge head at the other end for prying things open, making it particularly suitable for collecting rock specimens in the field.

[0003] According to a geological exploration hammer designed for easy folding (Announcement No.: CN221818549U), the aforementioned application utilizes a worm gear that rotates, which in turn drives the worm wheel through a threaded connection between the worm gear and the worm wheel. This worm wheel, in turn, drives the threaded rod to rotate, thereby adjusting the hammer. This method enables the worm wheel and worm gear to have a self-locking function, ensuring that the hammer remains almost stationary when the user does not need to adjust its position. This results in a stable gap between the hammer and the hammer column, preventing fluctuations in the gap size and making it easier for the user to lift objects while reducing the risk of slippage.

[0004] In complex outdoor environments, the pointed tip is sharp and hard, and is exposed, making it easy for users to be accidentally injured during carrying and storage due to collisions, shaking, or other unexpected situations. Utility Model Content

[0005] The purpose of this invention is to provide a foldable geological exploration hammer to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a geological exploration hammer that is easy to fold and use, comprising a hammer handle, an extension slidably connected inside the hammer handle, a front fork fixedly connected to the end of the extension slid, a hammer body hinged between the inner walls of the front fork, a pointed cone at one end of the hammer body, a flat end at the other end of the hammer body, a clamping assembly between the inner sides of the front fork, the clamping assembly comprising a pressure plate, the pressure plate fitting against the inner wall of the front fork, a lead screw rotatably connected to the side wall of the pressure plate, the lead screw passing through and threadedly connected to the end of the front fork, and a rotating wheel fixedly connected to the end of the lead screw.

[0007] Preferably, the pointed cone and the flat end near the hammer body are provided with positioning holes and threaded holes, and positioning blocks are fixedly connected to the upper and lower ends of the hammer body, with the positioning blocks inserted into the positioning holes.

[0009] Preferably, a guide rod is fixedly connected to the side wall of the pressure plate, the guide rod is slidably connected through and to the end of the fork, and the length of the guide rod is equal to that of the lead screw.

[0010] Preferably, the surface of the hammer handle is provided with a through hole, and a locking bolt is threaded into the through hole.

[0011] Preferably, an anti-slip sleeve is fixedly connected to the outer wall of the hammer handle.

[0012] Compared with the prior art, this utility model provides a geological exploration hammer that is easy to fold and use, and has the following beneficial effects:

[0013] 1. This foldable geological exploration hammer achieves flexible folding and fixation of the hammer body through the hinge between the hammer body and the front fork and the cooperation of the clamping component. When not in use, the pointed cone can be rotated and folded into the inside of the front fork and fixed by the pressure plate to avoid the sharp end being exposed and causing safety hazards.

[0019] like Figures 1-3As shown, this utility model provides a technical solution: a geological exploration hammer that is easy to fold and use, including a hammer handle 1, an extension handle 11 slidably connected inside the hammer handle 1, an anti-slip sleeve 12 fixedly connected to the outer wall of the hammer handle 1, a through hole opened on the surface of the hammer handle 1, and a locking bolt 13 threadedly connected in the through hole, the hammer handle 1 is hollow inside to accommodate the extension handle 11, the total length of the hammer handle 1 is extended by stretching the extension handle 11, and the extension length is fixed by tightening the locking bolt 13 to abut against the extension handle 11, adapting to different usage scenarios, the anti-slip sleeve 12 wraps the hammer handle 1 inside, increases the hand friction and prevents slipping during use.

[0020] The end of the extension handle 11 is fixedly connected to a front fork 2. A hammer body 3 is hinged between the inner walls of the front fork 2. The front fork 2 has a U-shaped structure. The hammer body 3 can rotate along the hinge point with the front fork 2, rotating the pointed cone 31 of the hammer body 3 to the inner side of the front fork 2. One end of the hammer body 3 is provided with a pointed cone 31, and the other end of the hammer body 3 is provided with a flat end 32. The pointed cone 31 is used to chisel hard rocks and break rock layers, and the flat end 32 is used to knock, flatten surfaces, or break block samples.

[0021] The pointed cone 31 and the flat end 32 are both provided with positioning holes 33 and threaded holes 34 on the surfaces near the hammer body 3. Positioning blocks 35 are fixedly connected to the upper and lower ends of the hammer body 3. The positioning blocks 35 are inserted into the positioning holes 33. Through the insertion and cooperation of the positioning blocks 35 and the positioning holes 33, the hammer body 3 achieves the initial positioning of the pointed cone 31 and the flat end 32, preventing the pointed cone 31 and the flat end 32 from rotating during installation. The side wall of the hammer body 3 is provided with a groove 36. The inner wall of the groove 36 is provided with two sets of symmetrically arranged through holes, and connecting bolts 37 are threadedly connected to the through holes. The connecting bolts 37 are threadedly connected to the threaded holes 34. The groove 36 provides installation space for the connecting bolt 37. The connecting bolt 37 is tightened to fix the pointed cone 31, the flat end 32, and the positioning block 35 and the positioning hole 33. The combination of the two makes the pointed cone 31, the flat end 32 and the hammer body 3 form a stable integral structure to meet the requirements of high-intensity operation. When the pointed cone 31 or the flat end 32 is worn, the connecting bolt 37 can be unscrewed to replace the new pointed cone 31 or the flat end 32 without replacing the entire tool, thus reducing the cost of use.

[0022] A clamping assembly 4 is provided between the inner sides of the front fork 2. The clamping assembly 4 includes a pressure plate 41, which is in contact with the inner wall of the front fork 2. A lead screw 42 is rotatably connected to the side wall of the pressure plate 41. The lead screw 42 passes through and is threaded to the end of the front fork 2. A rotating wheel 43 is fixedly connected to the end of the lead screw 42. The rotation of the rotating wheel 43 causes the lead screw 42 to rotate, bringing the pressure plate 41 closer to the side wall of the hammer body 3, thereby fixing the hammer body 3 and preventing it from rotating during use. When not in use, the rotating wheel 43 is rotated in the opposite direction, causing the pressure plate 41 to move away from the hammer body 3, and the hammer body 3 is rotated to rotate the pointed cone 31 to the inner side of the front fork 2. By rotating the rotating wheel 43 again, the pressure plate 41 is pressed against the pointed cone 31, thereby fixing the pointed cone 31 and improving the safety of the exploration hammer when it is not in use. A guide rod 44 is fixedly connected to the side wall of the pressure plate 41. The guide rod 44 passes through and is slidably connected to the end of the front fork 2. The guide rod 44 is the same length as the lead screw 42. The guide rod 44 is used to guide the movement of the pressure plate 41, so that the pressure plate 41 remains stable when moving.

[0023] In this utility model, when using it, the length of the hammer handle 1 can be adjusted according to the actual operation requirements: loosen the locking bolt 13, pull the extension handle 11 out from the hammer handle 1 to a suitable length, and then tighten the locking bolt 13 to fix the extension handle 11. At this time, hold the hammer handle 1 with the anti-slip sleeve 12 to avoid slipping when exerting force.

[0024] When the conical part 31 or the flat end 32 is worn and needs to be replaced, first unscrew the connecting bolt 37 in the groove 36 to separate the worn working end from the hammer body 3. Then, align the positioning hole 33 of the new conical part 31 or the flat end 32 with the positioning block 35 of the hammer body 3 and insert it to prevent rotation during installation. Finally, pass the connecting bolt 37 through the through hole of the groove 36 and screw it into the threaded hole 34 of the new conical part 31 or the flat end 32. After the replacement is completed, it can be used again.

[0025] After the operation is completed, rotate the wheel 43 in the reverse direction to loosen the pressure plate 41, rotate the hammer body 3 until the pointed cone 31 retracts into the inside of the front fork 2, and then rotate the wheel 43 in the forward direction to press the pressure plate 41 against the pointed cone 31, thus fixing the pointed cone 31 and preventing the sharp end from being exposed and causing safety hazards. At the same time, the extension handle 11 can be retracted into the hammer handle 1, and the locking bolt 13 can be tightened to reduce the overall size and make it easier to carry or store.

[0026] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
