Abstract
Description
Technical Field
[0001] This application relates to the field of hammer technology, and in particular to a geological hammer. Background Technology
[0002] Geological hammers are often used during geological surveys and play a significant role in geological work.
[0003] Existing geological hammers consist of a hammerhead and a handle (geological rod) that are directly fixed together. They lack adjustment capabilities, making it difficult to apply force to the rock and carry them. Furthermore, they take up a significant amount of space, which is inconvenient for workers.
[0004] To solve the above technical problems, the current method of adjusting the hammer head is to make it slide on the geological rod by adjusting the bolt. However, using bolt adjustment requires constantly tightening and loosening the fasteners, which requires additional tools, making the entire adjustment process inconvenient. Utility Model Content
[0005] Therefore, it is necessary to provide a geological hammer that is easy to extend and adjust.
[0006] This application provides a geological hammer, including a hammer head and a hammer handle. The hammer head is connected to the hammer handle via a connecting rod, and the connecting rod has at least two slots spaced apart along its length. One end of the hammer handle is sleeved around the connecting rod, and the hammer handle has a mounting cavity located outside the connecting rod. The geological hammer further includes:
[0007] A locking member, at least a portion of which is disposed within the mounting cavity, has a locking portion on the side facing the connecting rod that can engage with the slot. The locking member is arranged to move outward toward the direction away from the connecting rod to an unlocked position. When the locking member is in the unlocked position, the locking portion disengages from the slot, thereby allowing the connecting rod to be in an active state that can move relative to the hammer handle along its own length.
[0008] The first elastic element acts on the locking element, and causes the locking element to always tend to move inward toward the connecting rod to the locking position. When the locking element is in the locking position, the locking part at least partially protrudes from the mounting cavity and engages with the slot, thereby causing the connecting rod to be in a locked state locked with the hammer handle.
[0009] In one embodiment, the movement direction of the locking member is defined as a first direction. The locking member includes an extension rod extending along the first direction. The first end of the extension rod is connected to the locking part. The mounting cavity includes an outer wall plate and an inner wall plate arranged sequentially from the outside to the inside along the first direction. The inner wall plate has a through hole for the locking part to enter and exit. The extension rod passes through the outer wall plate, and the second end of the extension rod is located outside the mounting cavity.
[0010] In one embodiment, a sliding plate and a fixing rod fixedly connected to the inner wall plate are provided in the mounting cavity. The fixing rod extends along the first direction and slides in cooperation with the sliding plate. The first end of the extension rod is connected to the locking part through the sliding plate. The first elastic element is located between the sliding plate and the outer wall plate.
[0011] In one embodiment, the movement direction of the locking member is defined as a first direction, and the connecting rod is provided with the slots on two side walls that are arranged at relatively intervals along the first direction, and each side wall corresponds to the mounting cavity and the locking member.
[0012] In one embodiment, the hammer handle includes a geological rod and an adjusting ring connected to one end of the geological rod. The adjusting ring is sleeved around the connecting rod, and the mounting cavity is located inside the adjusting ring.
[0013] In one embodiment, the device further includes a fixing frame fixedly connected to the outside of the connecting rod and a storage box disposed within the fixing frame. The storage box and the fixing frame are slidably engaged along the length direction of the connecting rod, and the fixing frame has an opening on one side along the length direction of the connecting rod for the storage box to enter and exit.
[0014] In one embodiment, the hammer handle further includes two grips located on both sides of the connecting rod, the two grips being arranged at intervals along a second direction, the second direction being at an angle to the length direction of the connecting rod, and a buffer structure being provided between the connecting rod and the grips to allow the grips to move inward and outward along the second direction.
[0015] In one embodiment, the buffer structure includes a sleeve, a slider, and a second elastic member. The sleeve is connected to the connecting rod and extends along the second direction. One end of the slider is slidably engaged with the inner peripheral wall of the sleeve, and the other end of the slider extends out of the sleeve and is connected to the inner surface of the grip. The second elastic member is located between the slider and the connecting rod to give the slider a tendency to move outward along the second direction.
[0016] In one embodiment, the locking member and the grip are arranged sequentially along the circumference of the hammer handle, and the second direction is at an angle to the direction of movement of the locking member.
[0017] In one embodiment, the outer surfaces of both grips are arc-shaped surfaces that arch away from each other.
[0018] Compared with existing technologies, the geological hammer provided in this application only requires pulling the locking member outward when extension or retraction is needed. This causes the locking member to move away from the connection direction. When the locking member's locking part disengages from the slot, it releases the locking member from the connecting rod, allowing the connecting rod to move relative to the hammer handle to achieve extension or retraction. When the geological hammer extends or retracts to the appropriate length and the connecting rod needs to be locked, the locking member moves towards the connecting rod under the action of the first elastic element. When the locking member's locking part engages in the corresponding slot, it locks the connecting rod and the hammer handle together. The entire extension and retraction adjustment process requires no additional tools, is convenient to operate, and saves time and effort. Attached Figure Description

The terminology used in this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.
[0034] like Figures 1-7 As shown, this application discloses a geological hammer. Figures 1-3 As shown, the geological hammer includes a hammer head 1, a hammer handle 2, a connecting rod 3, a locking element 4, and a first elastic element 5. One end of the connecting rod 3 is connected to the hammer head 1, and the hammer handle 2 is slidably engaged with the connecting rod 3, meaning the hammer head 1 is connected to the hammer handle 2 via the connecting rod 3. The connecting rod 3 has at least two slots 31 spaced apart along its length; one end of the hammer handle 2 is fitted around the connecting rod 3, and the hammer handle 2 has a mounting cavity 221 located outside the connecting rod 3.
[0035] like Figures 2-4 As shown, at least a portion of the locking member 4 is disposed within the mounting cavity 221. The locking member 4 has a locking portion 41 on the side facing the connecting rod 3, which can engage with the slot 31. The locking member 4 is arranged to move outwards away from the connecting rod 3 to the unlocked position. When the locking member 4 is in the unlocked position, the locking portion 41 disengages from the slot 31, thereby allowing the connecting rod 3 to move relative to the hammer handle 2 along its length. The first elastic member 5 acts on the locking member 4, causing the locking member 4 to always tend to move inwards towards the connecting rod 3 to the locked position. When the locking member 4 is in the locked position, the locking portion 41 at least partially protrudes from the mounting cavity 221 and engages with the corresponding slot 31, thereby locking the connecting rod 3 to the hammer handle 2.
[0036] Understandably, when extension or retraction is needed, simply pull the locking member 4 outwards, causing it to move away from the connection direction. When the locking part 41 of the locking member 4 disengages from the slot 31, the locking member 4 releases the lock on the connecting rod 3, allowing the connecting rod 3 to move relative to the hammer handle 2 to achieve the extension or retraction of the geological hammer. When the geological hammer extends or retracts to the appropriate length and the connecting rod 3 needs to be locked, the locking member 4 moves towards the connecting rod 3 under the action of the first elastic member 5. When the locking part 41 of the locking member 4 engages in the slot 31, the locking member 4 locks the connecting rod 3 and the hammer handle 2 together. The entire extension and retraction adjustment process requires no additional tools, is convenient to operate, and saves time and effort.
[0037] The direction of movement of the locking member 4 is defined as the first direction A. The connecting rod 3 has slots 31 on two side walls spaced apart along the first direction A. Each side wall has a mounting cavity 221 and a locking member 4. Thus, the presence of slots 31 on the two side walls allows for more reliable locking of the connecting rod 3. Alternatively, slots 31 can also be provided on other side walls besides the two side walls.
[0038] The two sets of locking parts 4 and the slots 31 are engaged in the same way. The following explanation will take one of the sets as an example.
[0039] In this embodiment, such as Figures 3-5 As shown, the direction of movement of the locking member 4 is defined as the first direction A. The locking member 4 includes an extension rod 42 extending along the first direction A. The first end of the extension rod 42 is connected to the locking part 41. The mounting cavity 221 includes an outer wall plate 2211 and an inner wall plate 2212 arranged sequentially from the outside to the inside along the first direction A. The inner wall plate 2212 has a through hole 2213 for the locking part 41 to enter and exit. The extension rod 42 passes through the outer wall plate 2211, and the second end of the extension rod 42 is located outside the mounting cavity 221. In other embodiments, the mounting cavity 221 only includes the outer wall plate 2211.
[0040] Understandably, the second end of the extension rod 42 is located outside the mounting cavity 221 to facilitate pulling the extension rod 42.
[0041] To facilitate pulling the extension rod 42, a handle portion 421 is provided at the second end of the extension rod 42. Specifically, the handle portion 421 is formed by extending the outer peripheral wall of the extension rod 42 outward. The presence of the handle portion 421 also restricts the second end of the extension rod 42 from entering the mounting cavity 221.
[0042] In this embodiment, such as Figure 3As shown, a sliding plate 43 and a fixing rod 222 fixedly connected to the inner wall plate 2212 are provided in the mounting cavity 221. The fixing rod 222 extends along the first direction A and slides with the sliding plate 43. The first end of the extension rod 42 is connected to the locking part 41 through the sliding plate 43. The first elastic element 5 is located between the sliding plate 43 and the outer wall plate 2211. It can be understood that the fixed connection between the sliding plate 43 and the extension rod 42, and the sliding engagement between the sliding plate 43 and the fixing rod 222, can better guide the movement of the extension rod 42 and facilitate the installation of the first elastic element 5.
[0043] In this embodiment, there are two fixing rods 222, arranged side by side with intervals, and the extension rod 42 is located between the two fixing rods 222. Each fixing rod 222 corresponds to a first elastic element 5, which is a first spring sleeved on the periphery of the corresponding fixing rod 222.
[0044] In this embodiment, such as Figures 1-3 As shown, the hammer handle 2 includes a geological rod 21 and an adjusting ring 22 fixedly connected to one end of the geological rod 21. The adjusting ring 22 is sleeved around the connecting rod 3, and the mounting cavity 221 is located inside the adjusting ring 22. In other embodiments, the geological rod 21 and the adjusting ring 22 are an integral piece.
[0045] like Figure 1 and Figure 3 As shown, a fixing frame 6 and a storage box 61 are provided on the outer side of the connecting rod 3. The fixing frame 6 is fixedly connected to the connecting rod 3, and the storage box 61 is located inside the fixing frame 6 and slides with the fixing frame 6 along the length direction of the connecting rod 3. An opening for the storage box 61 to enter and exit is provided on one side of the fixing frame 6 along the length direction of the connecting rod 3. In this embodiment, the opening is located on the side of the fixing frame 6 away from the hammer head 1. Thus, the presence of the storage box 61 facilitates storage.
[0046] In this embodiment, after the hammer head 1 and the connecting rod 3 are inserted and fitted together, they are fixed by bolts 71 or screws. The screwdriver can be stored in the storage box 61, and the bolts 71 and / or screws can also be stored in the storage box 61. When it is necessary to disassemble or assemble the hammer head 1 and the connecting rod 3, simply pull open the storage box 61 and remove the screwdriver from it.
[0047] Furthermore, there are various ways in which the connecting rod 3 and the hammer head 1 can be inserted and mated, as illustrated in the diagram. Figure 1 and Figure 2As shown, the connecting rod 3 and the hammer head 1 are equipped with a plug-in portion 32 and a slot 11 that are matched for insertion. One of the plug-in portion 32 and the slot 11 is located on the connecting rod 3, and the other of the plug-in portion 32 and the slot 11 is located on the hammer head 1. In this embodiment, the plug-in portion 32 is located on the connecting rod 3, and the slot 11 is located on the hammer head 1. Specifically, one end of the connecting rod 3 is connected to the plug-in portion 32 through a connecting block 33. In addition, the side of the hammer head 1 has a connecting hole corresponding to the plug-in portion 32 for the bolt 71 to pass through. One end of the bolt 71 passing through the connecting hole is threadedly connected to the nut 72. With the tightening of the nut 72, the hammer head 1 and the connecting rod 3 are connected together.
[0048] In other embodiments, the slot 11 may be located on the connecting rod 3, and the insertion part 32 may be located on the hammer head 1.
[0049] The shape of the aforementioned plug-in portion 32 can vary, as long as it can match the slot 11. This embodiment will not elaborate further.
[0050] Furthermore, such as Figure 6 As shown, the hammer handle 2 also includes two grips 23 located on both sides of the connecting rod 3, meaning the connecting rod 3 is positioned between the two grips 23. The two grips 23 are spaced apart along a second direction B, which forms an angle with the length direction of the connecting rod 3. A buffer structure 8 is provided between the connecting rod 3 and the grips 23 to allow the grips 23 to move inward and outward along the second direction B. In other words, a buffer structure 8 is provided between each grip 23 and the connecting rod 3. The length direction of the connecting rod 3 is defined as the third direction C.
[0051] Understandably, when a user holds both grips 23, the presence of the buffer structure 8 can cushion the grips 23, thereby protecting the user's hands.
[0052] To better fit the user's hand, the outer surfaces of both grips 23 are curved surfaces 231 that arch away from each other. This makes it easier for the hand to grip the grips 23 securely.
[0053] The aforementioned buffer structure 8 may simply be an elastic element. In this embodiment, for example... Figure 6 and Figure 7 As shown, the buffer structure 8 includes a sleeve 81, a slider 82, and a second elastic member 83. The sleeve 81 is connected to the connecting rod 3 and extends along the second direction B. One end of the slider 82 is slidably engaged with the inner peripheral wall of the sleeve 81, and the other end of the slider 82 extends out of the sleeve 81 and is connected to the inner surface of the grip 23. The second elastic member 83 is located between the slider 82 and the connecting rod 3 so that the slider 82 has a tendency to move outward along the second direction B.
[0054] Understandably, when using a geological hammer to strike, the sliding member 82 moves back and forth along the second direction B under the action of the second elastic member 83. The force transmitted to the connecting rod 3 through the hammer head 1 is buffered by the cooperation of the second elastic member 83 and the sliding member 82. In this way, the force acting directly on the hand is reduced, thereby reducing the impact on the hand and achieving the purpose of protecting the hand.
[0055] In other embodiments, the handle 23 and the corresponding locking member 4 are arranged at intervals along the axial direction of the connecting rod 3. In this embodiment, the locking member 4 and the handle 23 are arranged sequentially along the circumference of the hammer handle 2, and the second direction B is at an angle to the movement direction of the locking member 4. In this way, it is convenient to operate the locking member 4 when the hand is holding the handle 23.
[0056] It should be noted that the second elastic element 83 mentioned above can be an elastic body, a spring, or a spring body. In this embodiment, the second elastic element 83 is a second spring.
[0057] In order to guide the sliding of the aforementioned slider 82, such as Figure 6 and Figure 7 As shown, the sliding member 82 and the inner peripheral wall of the sleeve 81 are fitted with a sliding protrusion 822 and a sliding groove 811, which extend along the second direction. One of the protrusion 822 and the sliding groove 811 is located on the outer peripheral wall of the sliding member 82, and the other is located on the inner peripheral wall of the sleeve 81. In other embodiments, the protrusion is located on the inner peripheral wall of the sleeve 81, and the sliding groove is located on the outer peripheral wall of the sliding member 82. In this embodiment, the protrusion 822 is located on the outer peripheral wall of the sliding member 82, and the sliding groove 811 is located on the inner peripheral wall of the sleeve 81. Specifically, a flange 821 extends outward from the outer peripheral wall of the sliding member 82, and the protrusion 822 is located on the outer surface of the flange 821.
[0058] Furthermore, for better guidance, there are at least two sets of the aforementioned protrusions 822 and grooves 811, which are arranged at intervals along the circumference of the slider 82.
[0059] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0060] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
