Description

Technical Field

[0001] This utility model belongs to the technical field of petroleum geological exploration tools, and in particular, relates to a geological hammer used for petroleum geological exploration. Background Technology

[0002] A geological hammer, also known as a hand hammer, is one of the basic tools used in petroleum geological exploration. It generally consists of a hammerhead and a handle, and is mainly used for breaking rocks or collecting surface rock samples from outcrops. During the continuous striking of rocks or rock samples with a geological hammer, the handle can cause significant impact to the operator's hand, easily leading to slippage and, in severe cases, injury.

[0003] Currently, to prevent hand slippage on the hammer handle during use, anti-slip sleeves are typically fitted onto the handle. However, due to the operating environment of geological hammers, these sleeves are prone to damage during use. Once damaged or ineffective, the sleeves, firmly attached to the handle, are difficult to replace, affecting the continued use of the geological hammer. Furthermore, while the anti-slip sleeves provide some protection, their shock absorption and cushioning effects are limited. The impact force generated during rock striking can easily cause pain or injury to the operator's hands, hindering continuous rock or rock sample breaking. Utility Model Content

[0006] Hammer head;

[0007] Hammer handle, connected to the hammer head;

[0008] An anti-slip sleeve is fitted onto the end of the hammer handle furthest from the hammer head; and

[0009] The locking assembly includes a first abutment fixedly disposed on the hammer handle, a second abutment for cooperating with the first abutment to clamp and position the anti-slip sleeve, a screw connected to the second abutment, a first tightening structure disposed between the first abutment and a first end of the anti-slip sleeve, and a second tightening structure disposed between the second abutment and a second end of the anti-slip sleeve. The hammer handle is provided with a threaded hole that threadedly engages with the screw. The first tightening structure includes a first frustoconical insert connected to the first abutment and a first tightening sleeve for inserting the first frustoconical insert to achieve a tightening connection. The first tightening sleeve is disposed on the end face of the first end of the anti-slip sleeve. The second tightening structure includes a second frustoconical insert abutting against the first abutment and a second tightening sleeve for inserting the second frustoconical insert to achieve a tightening connection. The second tightening sleeve is disposed on the end face of the second end of the anti-slip sleeve.

[0010] The anti-slip sleeve has a shock-absorbing and buffering groove on its inner circumferential surface. The shock-absorbing and buffering groove contains a plurality of shock-absorbing and buffering components. The plurality of shock-absorbing and buffering components are arranged at intervals along the axial direction of the hammer handle. Each shock-absorbing and buffering component includes a plurality of elastic elements arranged in a ring array around the hammer handle.

[0011] Furthermore, along the direction from the second abutment to the hammer head, the diameter of the hammer handle gradually increases to form a frustum-shaped tensioning shaft, and the diameter of the annular hole of the anti-slip sleeve gradually increases to form a tensioning sleeve adapted to the tensioning shaft.

[0012] Furthermore, the number of the first tightening structures is set to multiple, and the multiple first tightening structures are arranged at intervals along the circumference of the hammer handle, with the spacing between two adjacent first tightening structures being equal.

[0013] Furthermore, the number of the second tightening structures is set to multiple, and the multiple second tightening structures are arranged at intervals along the circumference of the screw, with the spacing between two adjacent second tightening structures being equal.

[0014] Furthermore, a first blind hole is provided on the end face of the first end of the anti-slip sleeve, and the first tightening sleeve is accommodated and positioned in the first blind hole so that the inner sidewall of the first blind hole can circumferentially tighten the first tightening sleeve.

[0015] Furthermore, a second blind hole is provided on the end face of the second end of the anti-slip sleeve, and the second tightening sleeve is accommodated and positioned in the second blind hole so that the inner sidewall of the second blind hole can exert a circumferential tightening effect on the first tightening sleeve.

[0016] Furthermore, the first frustoconical connector and / or the second frustoconical connector are frustoconical pins, and the first abutting member is an abutting protrusion ring protruding on the outer peripheral surface of the hammer handle. The first frustoconical connector and the abutting protrusion ring are fixedly connected or integrally formed on the side facing the anti-slip sleeve.

[0017] Further, the first tightening sleeve includes a first annular connecting sleeve connected to a first end of the anti-slip sleeve and a plurality of first tightening flaps connected to the first annular connecting sleeve and enclosing to form a first annular tightening sleeve, with a first tightening gap between two adjacent first tightening flaps; and / or, the second tightening sleeve includes a second annular connecting sleeve connected to a second end of the anti-slip sleeve and a plurality of second tightening flaps connected to the second annular connecting sleeve and enclosing to form a second annular tightening sleeve, with a second tightening gap between two adjacent second tightening flaps.

[0018] Furthermore, the elastic element is a helical spring, the axis of which is perpendicular to the axis of the hammer handle. The first free end of the helical spring is fixedly connected to the anti-slip sleeve, and the second free end of the helical spring elastically abuts against the outer circumferential surface of the hammer handle.

[0020] Compared with the prior art, one or more technical solutions in the embodiments of this utility model have at least one of the following beneficial effects:

[0021] The geological hammer for petroleum geological exploration in this embodiment of the invention features a first abutment on the hammer handle and a second abutment with a screw threaded into a threaded hole on the hammer handle. Simply tightening the screw into the threaded hole on the hammer handle allows for quick and easy positioning of the anti-slip sleeve at the end of the hammer handle furthest from the hammer head. Furthermore, a first tightening structure between the first abutment and the first end of the anti-slip sleeve, and a second tightening structure between the second abutment and the second end of the anti-slip sleeve, enhance the stability of the anti-slip sleeve's positioning on the hammer handle. When the anti-slip sleeve needs replacement, simply unscrewing the screw from the threaded hole on the hammer handle allows for easy and quick removal of the old anti-slip sleeve from the hammer handle, followed by positioning and installing the new anti-slip sleeve at the end of the hammer handle furthest from the hammer head. This facilitates convenient and quick replacement of the anti-slip sleeve on the geological hammer. Furthermore, the multiple shock-absorbing and buffering components in the shock-absorbing and buffering grooves on the anti-slip sleeve effectively dampen the impact force generated by the geological hammer during rock striking, making it less likely to cause strong impact on the operator's hands during rock striking. This facilitates the operator's continuous striking work of breaking rocks or rock samples with the geological hammer. Attached Figure Description

[0041] Please refer to the following: Figures 1 to 5The geological hammer for petroleum geological exploration provided in this embodiment of the present invention will now be described. Please refer to further details. Figure 1 , Figure 2 and Figure 3The geological hammer for petroleum geological exploration provided in this embodiment includes a hammer head 1, a hammer handle 2, an anti-slip sleeve 3, and a locking assembly 4. The hammer handle 2 is connected to the hammer head 1. Specifically, the hammer head 1 includes a hammer body 11 detachably connected to the hammer handle 2 via a threaded connection, a flat striking head 12 at one end of the hammer body 11, and a pointed striking head 13 at the other end of the hammer body 11. The anti-slip sleeve 3 can be, but is not limited to, a kit made of materials such as silicone, rubber, or flexible plastic. The anti-slip sleeve 3 is detachably fitted onto the end of the hammer handle 2 away from the hammer head 1. The outer surface of the anti-slip sleeve 3 is provided with an anti-slip structure 33, which can be an anti-slip texture, an anti-slip groove, or an anti-slip protrusion. The locking assembly 4 includes a first abutment 41, a second abutment 42, a screw 43, a first tightening structure 44, and a second tightening structure 45. The first abutment 41 is fixedly mounted on the hammer handle 2. The second abutment 42 is used to cooperate with the first abutment 41 to clamp and position the anti-slip sleeve 3. The screw 43 is connected to the second abutment 42. The hammer handle 2 is provided with a threaded hole 21 that is threadedly engaged with the screw 43. The first tightening structure 44 is located between the first abutment 41 and the first end 31 of the anti-slip sleeve 3. The first tightening structure 44 includes a first frustoconical insert 441 connected to the first abutment 41 and a first tightening sleeve 442 for the first frustoconical insert 441 to be inserted to achieve a tightening connection. The first tightening sleeve 442 is located on the end face of the first end 31 of the anti-slip sleeve 3. The second tightening structure 45 is disposed between the second supporting member 42 and the second end 32 of the anti-slip sleeve 3. The second tightening structure 45 includes a second frustoconical insert 451 that abuts against the first supporting member 41 and a second tightening sleeve 452 for the second frustoconical insert 451 to be inserted to achieve a tightening connection. The second tightening sleeve 452 is disposed on the end face of the second end 32 of the anti-slip sleeve 3. The inner circumferential surface of the anti-slip sleeve 3 is provided with a shock-absorbing buffer groove 6, and the shock-absorbing buffer groove 6 is provided with a plurality of shock-absorbing buffer components 5. The plurality of shock-absorbing buffer components 5 are arranged at intervals along the axial direction of the hammer handle 2. Each shock-absorbing buffer component 5 includes a plurality of elastic elements 51 that surround the hammer handle 2 and are arranged in a ring array. When it is necessary to install the anti-slip sleeve 3 on the hammer handle 2, firstly, put the anti-slip sleeve 3 on the end of the hammer handle 2 away from the hammer head 1. Then, screw the screw 43 into the threaded hole 21 on the hammer handle 2. During the process of tightening the screw 43 in the first direction, the screw 43 drives the second abutment 42 to press against the second end 32 of the anti-slip sleeve 3 towards the first abutment 41, so that the anti-slip sleeve 3 gradually moves along the axial direction of the hammer handle 2 and towards the first abutment 41 until the anti-slip sleeve 3 is interference-fitted on the end of the hammer handle 2 away from the hammer head 1, and the first end 31 of the anti-slip sleeve 3 abuts against the first abutment 41. Thus, the anti-slip sleeve 3 can be clamped and positioned by the first abutment 41 and the second abutment 42 to prevent the anti-slip sleeve 3 from moving axially relative to the hammer handle 2 and becoming loose or falling off.Furthermore, since a first tightening structure 44 is provided between the first supporting member 41 and the first end 31 of the anti-slip sleeve 3, and a second tightening structure 45 is provided between the second supporting member 42 and the second end 32 of the anti-slip sleeve 3, the anti-slip sleeve 3 can be locked between the first supporting member 41 and the second supporting member 42, effectively preventing the anti-slip sleeve 3 from rotating circumferentially relative to the hammer handle 2. When it is necessary to replace the anti-slip sleeve 3, simply loosen the screw 43 in the second direction and unscrew the screw 43 from the threaded hole 21 on the hammer handle 2. This will overcome the friction between the anti-slip sleeve 3 and the hammer handle 2, as well as the force of the first tightening structure 44 and the second tightening structure 45, allowing the old anti-slip sleeve 3 to be easily and quickly removed from the hammer handle 2. Then, the new anti-slip sleeve 3 can be repositioned and installed on the end of the hammer handle 2 away from the hammer head 1 using the aforementioned operating steps. This allows for convenient and quick replacement of the anti-slip sleeve 3 on the geological hammer, solving the problem in existing technologies where the anti-slip sleeve 3, which is adhered to the hammer handle 2, is difficult to replace after damage or failure. Furthermore, the impact force generated by the geological hammer during rock striking is effectively damped by the multiple damping components 5 in the damping groove 6 on the anti-slip sleeve 3. This significantly reduces the impact force on the operator's hands during rock striking, minimizing the risk of severe impact and pain or injury. This facilitates continuous rock or rock sample breaking operations.

[0042] The geological hammer for petroleum geological exploration provided in this embodiment of the invention, compared with the prior art, features a first supporting member 41 on the hammer handle 2 and a screw 43 threadedly connected to a threaded hole 21 on the hammer handle 2 on a second supporting member 42. Simply tightening the screw 43 into the threaded hole 21 on the hammer handle 2 allows for quick and easy positioning of the anti-slip sleeve 3 at the end of the hammer handle 2 away from the hammer head 1. Furthermore, a first tightening structure 44 is provided between the first supporting member 41 and the first end 31 of the anti-slip sleeve 3, and a second tightening structure 45 is provided between the second supporting member 42 and the second end 32 of the anti-slip sleeve 3, enhancing the stability of the anti-slip sleeve 3 on the hammer handle 2. When the anti-slip sleeve 3 needs to be replaced, simply unscrewing the screw 43 from the threaded hole 21 on the hammer handle 2 allows for easy and quick removal of the old anti-slip sleeve 3 from the hammer handle 2, and then positioning and installing the new anti-slip sleeve 3 at the end of the hammer handle 2 away from the hammer head 1. This allows for convenient and quick replacement of the anti-slip sleeve 3 on the geological hammer. Furthermore, the multiple shock-absorbing and buffering components 5 in the shock-absorbing and buffering grooves 6 on the anti-slip sleeve 3 effectively dampen and buffer the impact force generated by the geological hammer during rock striking, making it less likely to cause strong impacts to the operator's hands during rock striking. This facilitates continuous striking work for the operator to break rocks or rock samples with the geological hammer.

[0043] Please refer to further details. Figure 2 and Figure 3 In some embodiments, along the direction of the second abutment 42 pointing towards the hammer head 1, the diameter of the hammer handle 2 gradually increases to form a truncated cone-shaped tensioning shaft 22, and the diameter of the annular hole of the anti-slip sleeve 3 gradually increases to form a tensioning sleeve adapted to the tensioning shaft 22. When the second abutment 42 presses against the anti-slip sleeve 3 and moves towards the hammer head 1, the hammer handle 2 can form a tensioning connection with the anti-slip sleeve 3. On the one hand, this can enhance the tightness of the connection between the anti-slip sleeve 3 and the hammer handle 2. On the other hand, it can help the hammer handle 2 press against the shock-absorbing buffer assembly 5 in the shock-absorbing buffer groove 6, so that the impact force generated by the geological hammer during the rock-hitting process can be offset by the elastic action of the shock-absorbing buffer assembly 5, thereby improving the shock-absorbing buffer effect of the shock-absorbing buffer assembly 5 on the impact force generated by the geological hammer during the rock-hitting process.

[0047] Please refer to further details. Figure 2 , Figure 3 and Figure 5 In some embodiments, in order to further enhance the tightness of the connection between the second abutment 42 and the second end 32 of the antislip sleeve 3, a second blind hole 8 is provided on the end face of the second end 32 of the antislip sleeve 3, and the second expansion sleeve 452 is accommodated and positioned in the second blind hole 8 so that the inner sidewall of the second blind hole 8 can play a circumferential tightening role on the first expansion sleeve 442.

[0048] Please refer to further details. Figure 3 , Figure 4 and Figure 5 In some embodiments, the first frustoconical connector 441 and / or the second frustoconical connector 451 are frustoconical pins, so that when the first frustoconical connector 441 and / or the second frustoconical connector 451 are inserted into the first expansion sleeve 442 and / or the second expansion sleeve 452, a good expansion connection effect can be achieved. The first abutment 41 is an abutment protrusion ring protruding from the outer peripheral surface of the hammer handle 2, and the first frustoconical connector 441 is fixedly connected to or integrally formed with the abutment protrusion ring facing the anti-slip sleeve 3. The second abutment 42 is an abutment disc that can abut against the end face of the second end 32 of the anti-slip sleeve 3, and the abutment disc facing the anti-slip sleeve 3 is fixedly connected to the screw 43. It can be understood that the abutment disc can also be integrally formed with the screw 43.

[0049] Please refer to further details. Figure 2 , Figure 3 and Figure 4 In some embodiments, in order to further improve the tightening connection effect, the first tightening sleeve 442 includes a first annular connecting sleeve 4421 connected to the first end 31 of the anti-slip sleeve 3 and a plurality of first tightening petals 4422 connected to the first annular connecting sleeve 4421 and enclosing it to form a first annular expansion sleeve, with a first tightening gap between two adjacent first tightening petals 4422.

[0050] Please refer to further details.

[0051] Please refer to further details. Figure 2 and Figure 3 In some embodiments, the elastic element 51 is a helical spring, the axis of which is perpendicular to the axis of the hammer handle 2. The first free end of the helical spring is fixedly connected to the anti-slip sleeve 3, and the second free end of the helical spring elastically abuts against the outer circumferential surface of the hammer handle 2. This allows the impact force generated by the geological hammer during rock striking to be offset by the elastic action of the helical spring, thereby improving the shock absorption and buffering effect of the shock absorption and buffering assembly 5 on the impact force generated by the geological hammer during rock striking.

[0052] Please refer to further details. Figure 2 and Figure 3In some embodiments, the anti-slip sleeve 3 has a cylindrical inflatable space 9 inside, into which gas or liquid can be filled. This creates an inflatable airbag structure surrounding the shock-absorbing buffer assembly 5 inside the anti-slip sleeve 3. Through the synergistic shock absorption effect of the inflatable airbag structure and the shock-absorbing buffer assembly 5, the impact force generated by the geological hammer during rock striking can be further eliminated, thus improving the shock absorption effect of the shock-absorbing buffer assembly 5 on the impact force generated by the geological hammer during rock striking. In addition, the cylindrical inflatable space 9 inside the anti-slip sleeve 3, into which gas or liquid can be filled, improves the comfort of the operator's hand holding the anti-slip sleeve 3 and increases the friction between the operator's hand and the anti-slip sleeve 3, which helps to prevent the operator's hand from slipping off the hammer handle 2.
