[0031] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0032] Please refer to Figure 1-8 , a geological hammer for field geological exploration work provided by an embodiment of the present invention includes a hammer head 1 and a hammer handle 2, and the hammer head 1 and the hammer handle 2 are fixed to each other through a locking mechanism. The locking mechanism includes:

[0033] A hinge assembly 3 that enables the hammer head 1 to deflect around the end of the hammer handle 2;

[0034] A lock pin assembly 4 that fixes the hammer head 1 and the hammer handle 2 to each other.

[0035] Specifically, the hammer head 1 is made of rigid material. One end of the hammer head 1 is a wedge-shaped end, and the other end of the hammer head 1 is a cylindrical end. The hinge assembly 3 can be selected as a hinge seat fixed in the middle of the hammer head 1. The middle of the hinge seat is movably clamped with the top end of the hammer handle 2. A shaft seat shaft fixedly passing through the hammer handle 2 is rotatably installed on the hinge seat, so that the hammer head 1 can deflect around the end of the hammer handle 2. The locking pin assembly 4 includes two locking pin holes opened on the side ear plates of the hinge seat. The locking pin holes can be adaptively inserted with a U-shaped pin. When the U-shaped pin is inserted into the locking pin hole, at this time, the hammer handle 2 is located inside the U-shaped pin, and both sides of the hammer handle 2 are in contact with the U-shaped pin, so as to limit the two sides where the hammer handle 2 can deflect, achieving the effect of fixing the hammer head 1 and the hammer handle 2. When the U-shaped pin is completely separated from the locking pin hole, the deflection limit of the hammer head 1 and the hammer handle 2 is released;

[0036] During the actual use process, when the length direction line of the hammer head 1 is perpendicular to the length direction line of the hammer handle 2, at this time, the U-shaped pin is inserted into the locking pin hole, so as to fix the hammer head 1 and the hammer handle 2. The insertion end of the U-shaped pin penetrates through the hinge seat, and an anti-disengagement sleeve is spirally sleeved on the insertion end of the U-shaped pin to prevent the U-shaped pin from disengaging from the hinge seat. When it is necessary to store the geological hammer, at this time, just completely separate the U-shaped pin from the locking pin hole, so that the hammer head 1 deflects at the end of the hammer handle 2 through the hinge assembly 3, making the included angle between the length direction line of the hammer head 1 and the length direction line of the hammer handle 2 smaller, thereby reducing the radial space occupied by the geological hammer and facilitating the storage and carrying of the geological hammer.

[0037] In another embodiment provided by the present invention, the hammer head 1 includes a hammer column block 1.1. The cross-section of the hammer column block 1.1 is rectangular. A notch portion 1.2 is opened at one end of the hammer column block 1.1, so that the hammer head 1 forms a structure with one end being a wedge-shaped end and one end being a cylindrical end. Among them, the notch portion 1.2 is a rectangular notch on the hammer column block 1.1. The rectangular notch includes a first plane portion 1.21. One end of the first plane portion 1.21 close to the middle of the hammer column block 1.1 is provided with a second plane portion 1.22. The second plane portion 1.22 is perpendicular to the first plane portion 1.21, and the first plane portion 1.21 is parallel to the length direction line of the hammer column block 1.1.

[0038] In another embodiment of the present invention, the hinge assembly 3 includes a notch groove 3.1 provided on the notch portion 1.2, and an inner wall of the notch groove 3.1 is rotatably mounted with a shaft column block 3.2 fixed to the hammer handle 2. Specifically, the notch groove 3.1 is provided on the second plane portion 1.22 of the notch portion 1.2, and the notch groove 3.1 has a rectangular groove space. The notch groove 3.1 has four groove wall surfaces, specifically two opposite and parallel groove side surfaces 3.11, a groove bottom surface 3.12 and a contact surface 3. 13, the groove bottom surface 3.12 is perpendicular to the abutment surface 3.13, the groove bottom surface 3.12 and the abutment surface 3.13 are between the two groove side surfaces 3.11, the abutment surface 3.13 of the notch groove 3.1 is flush with the first plane portion 1.21, and the two groove side surfaces 3.11 are provided with blind holes 3.14 adapted for rotational insertion of the shaft column block 3.2, the axis center line of the shaft column block 3.2 is perpendicular to the axis center line of the hammer handle 2, and the hammer handle 2 can deflect in the notch groove 3.1 with the shaft column block 3.2 as the center of the circle;

[0039] In actual use, when the side surface of the hammer handle 2 is parallel to the groove bottom surface 3.12, the length direction line of the hammer handle 2 is perpendicular to the length direction line of the hammer head 1, and the geological hammer is in an unfolded state; when the side surface of the hammer handle 2 is parallel to the contact surface 3.13, the length direction line of the hammer handle 2 is parallel to the length direction line of the hammer head 1, and the geological hammer is in a folded state.

[0040] In another embodiment provided by the present invention, the lock pin assembly 4 includes a latch port 4.1 penetrating through the bottom of the notch groove 3.1, and a receiving cavity 4.2 is provided at one end of the hammer handle 2 located in the notch groove 3.1. A latch rod 4.3 capable of extending into the latch port 4.1 is provided in the receiving cavity 4.2. The latch rod 4.3 can perform telescopic movement in the receiving cavity 4.2. The insertion end of the latch rod 4.3 is connected to the bottom of the receiving cavity 4.2 by a limiting rope. The latch rod 4.3 cannot be completely separated from the receiving cavity 4.2. The latch rod 4.3 can fix the hammer head 1 and the hammer handle 2. Specifically, the latch port 4.1 is located in the notch groove 3.1. .1, the latch port 4.1 penetrates the hammer head 1, the latch port 4.1 can be plugged with the latch rod 4.3, the accommodating cavity 4.2 is a cylindrical cavity, the center line of the accommodating cavity 4.2 coincides with the axial line of the hammer handle 2, the latch rod 4.3 can be completely retracted into the accommodating cavity 4.2, the latch rod 4.3 can be plugged with the accommodating cavity 4.2, the axial line of the accommodating cavity 4.2 and the axial line of the latch port 4.1 can be in the same straight line, and a latch blind hole 3.15 is provided on the bottom surface 3.12 of the notch groove 3.1, and the latch blind hole 3.15 can be plugged with the latch rod 4.3;

[0041] During actual use, when the geological hammer is in the unfolded state, the pin hole 4.1 can be aligned with the end of the pin rod 4.3. When one end of the pin rod 4.3 is inserted into the pin hole 4.1, the other end of the pin rod 4.3 still remains in the receiving cavity 4.2. At this time, the locking pin assembly 4 is in the unfolded and locked state, thereby restricting the deflection of the hammer handle 2 in the notch groove 3.1. At the same time, when the hammer head 1 is impacted, the acting force on the inner wall of the pin hole 4.1 can act on the pin rod 4.3, sharing the radial force on the shaft column block 3.2 and reducing the probability of loosening of the shaft column block 3.2 during long-term use. It also keeps the geological hammer in a stable unfolded state. When the geological hammer is in the folded state, the blind pin hole 3.15 can be aligned with the end of the pin rod 4.3. When one end of the pin rod 4.3 is inserted into the blind pin hole 3.15, the other end of the pin rod 4.3 still remains in the receiving cavity 4.2. At this time, the locking pin assembly 4 is in the retracted and locked state, thus keeping the geological hammer in a stable retracted state all the time.

[0042] In another embodiment provided by the present invention, a regulating component 5 is installed on the hammer handle 2. The regulating component 5 can control whether the pin rod 4.3 is inserted into the pin hole 4.1, and the regulating component 5 can control whether the pin rod 4.3 is inserted into the blind pin hole 3.15. The regulating component 5 includes an inner cavity 5.1 opened at the bottom end of the hammer handle 2. A threaded rod 5.2 is spirally penetrated between the inner cavity 5.1 and the receiving cavity 4.2. One end of the threaded rod 5.2 is rotatably connected to the end of the pin rod 4.3, and the other end of the threaded rod 5.2 is located in the inner cavity 5.1. The inner cavity 5.1 is a cylindrical cavity, and the center line of the inner cavity 5.1 coincides with the axis line of the hammer handle 2. A cross bar 2.4 fixed to the end of the threaded rod 5.2 is provided in the inner cavity 5.1. The axis line of the cross bar 2.4 is perpendicular to the axis line of the threaded rod 5.2. The cross bar 2.4 is suspended in the inner cavity 5.1, and the middle part of the cross bar 2.4 is fixed to the end of the threaded rod 5.2.

[0043] During actual use, when the threaded rod 5.2 rotates forward, the threaded rod 5.2 moves towards the receiving cavity 4.2 at this time, thereby pushing the pin rod 4.3 out of the receiving cavity 4.2, so as to facilitate insertion into the corresponding pin hole 4.1 or blind pin hole 3.15. When the threaded rod 5.2 rotates reversely, the threaded rod 5.2 moves towards the inner cavity 5.1 at this time, thereby retracting the pin rod 4.3 into the receiving cavity 4.2, facilitating separation from the corresponding pin hole 4.1 or blind pin hole 3.15.

[0044] In another embodiment provided by the present invention, a force arm cylinder 2.1 is threadedly sleeved at one end of the hammer handle 2 away from the hammer head 1 to increase the force arm length of the hammer handle 2. The inner diameter value of the force arm cylinder 2.1 is greater than the diameter value of the hammer handle 2. An internal thread cylinder 2.2 capable of being threadedly connected to the hammer handle 2 is fixed at one end of the force arm cylinder 2.1. Specifically, the internal thread cylinder 2.2 is fixed to the end of the force arm cylinder 2.1 with a cylinder bottom. A vertical rod 2.3 is fixed inside the internal thread cylinder 2.2. The axis line of the vertical rod 2.3 is parallel to the axis line of the internal thread cylinder 2.2. The vertical rod 2.3 is located at a non-central position inside the internal thread cylinder 2.2. When the internal thread cylinder 2.2 rotates, the vertical rod 2.3 can drive a cross bar 2.4 fixed to a threaded rod 5.2. Thread lines adapted to the threads on the inner wall of the internal thread cylinder 2.2 are provided on the outer side of the bottom end of the hammer handle 2, so as to facilitate the threaded connection between the bottom end of the hammer handle 2 and the internal thread cylinder 2.2, and further fix the force arm cylinder 2.1 to the bottom end of the hammer handle 2, increasing the force arm length of the hammer handle 2;

[0045] During actual use, the mouth of the internal thread cylinder 2.2 is aligned with the bottom end of the hammer handle 2 and sleeved in, and then rotated, so that the vertical rod 2.3 generates a positive circumferential driving force on the cross bar 2.4. At this time, the threaded rod 5.2 rotates forward, and the pin rod 4.3 extends out of the accommodation cavity 4.2, so that the geological hammer in the unfolded state can be locked, that is, the locking pin assembly 4 is in the unfolded and locked state. Similarly, when the internal thread cylinder 2.2 is rotated away from the bottom end of the hammer handle 2, at this time, the vertical rod 2.3 generates a reverse circumferential driving force on the cross bar 2.4, so that the threaded rod 5.2 rotates reversely, and the pin rod 4.3 retracts into the accommodation cavity 4.2, so as to unlock the geological hammer in the unfolded state. The locking pin assembly 4 is in the unlocking state, and the hammer handle 2 can deflect around the shaft column block 3.2 in the notch groove 3.1.

[0046] In another embodiment provided by the present invention, spiral threads 2.5 are provided inside the force arm cylinder 2.1, and a thread ring 2.6 spirally adapted to the spiral threads 2.5 is fixedly sleeved on the hammer handle 2. When the geological hammer is in the folded state, the force arm cylinder 2.1 separated from the hammer handle 2 is sleeved on the folded geological hammer. When the folded geological hammer is inside the force arm cylinder 2.1, the spiral lines on the outer side of the thread ring 2.6 are spirally matched with the spiral threads 2.5 inside the force arm cylinder 2.1, so as to play a protective role of a storage bag outside the geological hammer and facilitate the storage and carrying of the geological hammer.

[0047] In another embodiment provided by the present invention, anti-slip patterns are provided on the outer circumference of the barrel of the lever arm cylinder 2.1. Thus, when the lever arm cylinder 2.1 increases the length of the lever arm on the hammer handle 2, the anti-slip patterns play an anti-slip role, facilitating the user's grip. At the same time, the shoulder strap 2.7 can be wound around the arm part, which helps prevent the lever arm cylinder 2.1 from flying out of the hand. The shoulder strap 2.7 is installed on the barrel of the lever arm cylinder 2.1. When the lever arm cylinder 2.1 functions as a storage bag outside the geological hammer, the shoulder strap 2.7 facilitates the user to carry it on the back.

[0048] In another embodiment provided by the present invention, the cross-section of the pin rod 4.3 is a rectangular surface, and the cross-section of the receiving cavity 4.2 is also a rectangular surface that is adaptively inserted with the pin rod 4.3. The cross-sections of the pin hole 4.1 and the pin blind hole 3.15 are both rectangular. The pin rod 4.3 can be adaptively inserted into the pin hole 4.1, and the pin rod 4.3 can be adaptively inserted into the pin blind hole 3.15. Further, two parallel inner walls in the pin hole 4.1 are the first inner walls 4.11 of the hole, and the other two parallel inner walls of the pin hole 4.1 are the second inner walls 4.12 of the hole. Blind insertion holes 6 are provided on the second inner walls 4.12 of the hole. The axis lines of the blind insertion holes 6 on the second inner walls 4.12 of the hole are on the same straight line, and the axis line of the blind insertion hole 6 is perpendicular to the center line of the pin hole 4.1. One side of the pin rod 4.3 parallel to the first inner wall 4.11 of the hole is the first side surface of the rod, and one side of the pin rod 4.3 parallel to the second inner wall 4.12 of the hole is the second side surface of the rod. A through hole 7 is provided on the first side surface of the rod of the pin rod 4.3. Elastic telescopic rods 8 are installed at both ends of the through hole 7. The ends of the elastic telescopic rods 8 extend out of the first side surface of the rod of the pin rod 4.3, so the elastic telescopic rods 8 are in an extended state. The ends of the elastic telescopic rods 8 retract into the first side surface of the rod of the pin rod 4.3, so the elastic telescopic rods 8 are in a retracted state. It should be particularly noted that the cross-section specifications and shapes of the cavity of the receiving cavity 4.2 are the same as those of the cross-section of the pin hole 4.1. The two ends of the pin hole 4.1 and the ports of the receiving cavity 4.2 are all outward-expanded ports, and the maximum diameter value of the outward-expanded port is greater than the maximum extension distance of the elastic telescopic rods 8 in the extended state.

[0049] In actual use, when the through hole 7 is located outside the bolt hole 4.1 and the accommodation cavity 4.2, the elastic telescopic rod 8 is in the extended state at this time. When the through hole 7 is located inside the bolt hole 4.1 or the accommodation cavity 4.2, the elastic telescopic rod 8 is in the retracted state at this time. During the process of the elastic telescopic rod 8 entering the bolt hole 4.1 or the accommodation cavity 4.2 from the outside, it will slide along the wall surface of the outward expansion port. The outward expansion port is the annular inclined surface part at both ends of the bolt hole 4.1 and the port of the accommodation cavity 4.2. Enlarging the outward expansion port is to increase the area of both ends of the bolt hole 4.1 and the port of the accommodation cavity 4.2, similar to the chamfering of the hole opening in mechanical hole processing, which is convenient for the elastic telescopic rod 8 to enter the bolt hole 4.1 or the accommodation cavity 4.2. When the bolt locking assembly 4 is in the deployed and locked state, the bolt rod 4.3 penetrates and extends out of the bolt hole 4.1, and the elastic telescopic rod 8 is in the extended state at this time.

[0050] In another embodiment provided by the present invention, one end of the bolt rod 4.3 inserted into the accommodation cavity 4.2 is the insertion end. A through hole 9 communicating with the through hole 7 is provided at the insertion end of the bolt rod 4.3. The center line of the through hole 9 coincides with the axis line of the bolt rod 4.3. A driving rod 10 is movably inserted into the through hole 9. One end of the driving rod 10 extending out of the through hole 9 is rotatably connected to the end of the threaded rod 5.2. The driving rod 10 will not rotate circumferentially due to the circumferential rotation of the threaded rod 5.2.

[0051] The elastic telescopic rod 8 includes a containing cylinder 8.1 adapted to be inserted into the through hole 7. The mouth of the containing cylinder 8.1 faces the port of the through hole 7. An activity column 8.2 is adaptably inserted into the containing cylinder 8.1. The activity column 8.2 is connected to the bottom wall of the containing cylinder 8.1 through a spring 8.3. When the spring 8.3 is in the natural state, the activity column 8.2 extends out of the mouth of the containing cylinder 8.1. When the spring 8.3 is in the compressed and deformed state, the activity column 8.2 retracts into the containing cylinder 8.1. Among them, the mouth end of the containing cylinder 8.1 is flush with the first rod side surface of the bolt rod 4.3. At this time, it is the near-hole position of the elastic telescopic rod 8 at the through hole 7. The mouth end of the containing cylinder 8.1 retracts into the through hole 7. At this time, it is the alienated position of the elastic telescopic rod 8 at the through hole 7.

[0052] In actual use, when the elastic telescopic rod 8 is at the near-mouth position of the through-hole 7, when the through-hole 7 is outside the pin hole 4.1 and the accommodating cavity 4.2, at this time the elastic telescopic rod 8 is in the extended state, and at the same time the spring 8.3 is in the natural state. When the through-hole 7 is inside the pin hole 4.1 or the accommodating cavity 4.2, at this time the elastic telescopic rod 8 is in the retracted state, and at the same time the spring 8.3 is in the compressed deformation state. During the process of the elastic telescopic rod 8 entering the pin hole 4.1 or the accommodating cavity 4.2 from the outside, it will slide along the wall surface of the outwardly expanding opening, so that the elastic telescopic rod 8 changes from the extended state to the retracted state;

[0053] When the elastic telescopic rod 8 is at the distant position of the through-hole 7, at this time the spring 8.3 of the elastic telescopic rod 8 is in the natural state, and the movable column 8.2 is also completely inside the through-hole 7, so that it will never come into contact with the pin hole 4.1 and the accommodating cavity 4.2;

[0054] Furthermore, a connecting piece 8.4 is fixed to the bottom end of the barrel of the holding barrel 8.1. The plate surface of the connecting piece 8.4 is parallel to the axis line of the driving rod 10. A long strip track opening 8.5 is provided on the connecting piece 8.4. The included angle between the length direction line of the long strip track opening 8.5 and the center line of the holding barrel 8.1 is 45 degrees. A U-shaped frame 8.6 fixed to the driving rod 10 is provided in the through-hole 7. A shaft roller 8.7 that movably penetrates through the long strip track opening 8.5 is rotatably installed on the U-shaped frame 8.6;

[0055] During actual use, when the threaded rod 5.2 rotates forward, the driving rod 10 is subjected to the axial driving force of the threaded rod 5.2, so that the driving rod 10 moves towards the inner wall of the through port 7. At the same time, an axial force in the direction of the axis of the through port 7 is generated by the extrusion between the shaft roller 8.7 and the side wall of the long strip track port 8.5, and the direction of the component force is away from the channel port 9. Furthermore, the storage cylinder 8.1 moves towards the end of the through port 7. When the end of the driving rod 10 comes into contact with the inner wall of the through port 7, the mouth end of the storage cylinder 8.1 is flush with the first rod side surface of the plug pin rod 4.3. At this time, as the threaded rod 5.2 continues to rotate forward, the driving rod 10 generates a thrust on the side wall of the through port 7, and then the plug pin rod 4.3 is pushed out of the accommodation cavity 4.2; Similarly, when the threaded rod 5.2 rotates reversely, the driving rod 10 is subjected to the axial pulling force of the threaded rod 5.2, so that the driving rod 10 moves away from the inner wall of the through port 7. At the same time, an axial force in the direction of the axis of the through port 7 is generated by the extrusion between the shaft roller 8.7 and the side wall of the long strip track port 8.5, and the direction of the component force is towards the channel port 9. Furthermore, the storage cylinder 8.1 moves towards the inside of the through port 7. When the end of the driving rod 10 reaches the maximum distance from the inner wall of the through port 7, the mouth end of the storage cylinder 8.1 is completely located inside the through port 7. At this time, as the threaded rod 5.2 continues to rotate reversely, under the pulling action of the driving rod 10 through the U-shaped frame 8.6 and the shaft roller 8.7, the plug pin rod 4.3 is subjected to a pulling force along the axial direction of the plug pin rod 4.3 generated by the elastic telescopic rod 8 in the through port 7. Then the plug pin rod 4.3 retracts back into the accommodation cavity 4.2 again, and then the lock pin assembly 4 is in an unlocked state.

[0056] In another embodiment provided by the present invention, when the geological hammer is in the folded state, manually rotate the threaded rod 5.2 forward at this time, so that the locking pin assembly 4 is in the storage and locking state. The geological hammer in this state is in a semi-storage state, and the pin hole 4.1 on the semi-storage state geological hammer is in a vacant state. In actual use, switch the locking pin assembly 4 on another geological hammer in the unfolded state to the unfolded locking state, and then the geological hammer can be used normally. The side surface of the hammer head 1 of the geological hammer where the pin hole 4.1 is opened is the hammer top surface. When in use, make the hammer top surface of the hammer head 1 of the semi-storage state geological hammer parallel to the hammer top surface of the hammer head of the normally used geological hammer, and at the same time make the length direction line of the hammer head 1 of the semi-storage state geological hammer perpendicular to the length direction line of the hammer head 1 of the normally used geological hammer in different planes. At this time, the first inner wall 4.11 of the pin hole 4.1 on the semi-storage state geological hammer and the second inner wall 4.12 of the pin hole 4.1 on the normally used geological hammer are in the same plane, and the pin rod 4.3 of the normally used geological hammer extends out of the pin hole 4.1. When the extended part of the pin rod 4.3 of the normally used geological hammer is inserted into the pin hole 4.1 on the semi-storage state geological hammer, the elastic telescopic rod 8 on the pin rod 4.3 of the normally used geological hammer can be adaptively inserted into the blind hole 6 on the inner wall of the pin hole 4.1 on the semi-storage state geological hammer, so as to prevent the pin rod 4.3 of the normally used geological hammer from detaching from the pin hole 4.1 on the semi-storage state geological hammer, fix the semi-storage state geological hammer on the normally used geological hammer, increase the weight of the hammer head 1 of the normally used geological hammer, increase the inertial force of the hammer head 1 of the normally used geological hammer, which is beneficial to reducing the number of strikes, improving the rock breaking speed, and accelerating the working efficiency;

[0057] When it is necessary to separate the semi-storage state geological hammer from the normally used geological hammer, only need to switch the locking pin assembly 4 on the normally used geological hammer to the unlocking state at this time, and specific operations can be carried out according to the actual situation. For example, screw the force arm cylinder 2.1 on the normally used geological hammer away from the end of the hammer handle 2, or reverse rotation of the threaded rod 5.2 can also achieve this.

[0058] Only some exemplary embodiments of the present invention are described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
