Description

Technical Field

[0001] This utility model relates to the field of lightweight powered penetrometers, and more specifically, to a lightweight powered penetrometer that can be quickly disassembled and assembled. Background Technology

[0002] In the field of geotechnical engineering investigation, the lightweight dynamic penetrometer is a widely used field testing device for determining the mechanical properties of soil layers. It obtains soil parameters by impacting the penetrometer probe with a falling hammer. Currently, in most penetrometers, the connection between the guide rod and the probe rod is fixed by threads. While this method is simple in structure, it requires multiple tightening operations in actual field operations, making the assembly and disassembly process cumbersome, time-consuming, and inefficient. Especially during frequent assembly, disassembly, and transportation, the threads are prone to wear and dirt adhesion, leading to loose connections or difficulty in disassembly, severely impacting testing efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a lightweight, power penetrometer that can be quickly assembled and disassembled. It is easy to operate, has a reliable connection, and can effectively improve work efficiency.

[0004] A lightweight, power penetrometer with quick assembly and disassembly includes a guide rod, a penetrometer rod, a penetrometer probe, and a drop hammer. One end of the penetrometer rod is provided with an impact seat, and the other end of the penetrometer rod is connected to the penetrometer probe. The drop hammer is sleeved on the guide rod and can slide along it. The impact seat has a mounting hole, and the outer periphery of the mounting hole is provided with an elastic snap-fit ​​and an unlocking assembly. One end of the guide rod has a pin with an annular groove. When the pin is inserted into the mounting hole, the elastic snap-fit ​​extends into the annular groove. The unlocking assembly is configured to slide radially along the impact seat to separate the elastic snap-fit ​​from the annular groove.

[0005] In the above technical solution, the guide rod and the probe rod are respectively equipped with a pin and a mounting hole. During assembly, the pin can be inserted into the mounting hole, and the elastic locking component automatically engages with the annular groove under the action of elastic force, thereby achieving a quick connection between the guide rod and the impact seat without the need for tightening. When separation is required, the unlocking component is pressed, causing it to slide radially along the impact seat, thereby separating the elastic locking component from the annular groove. The operation is simple and convenient, effectively improving disassembly efficiency and enhancing the convenience and efficiency of operation while ensuring a stable connection.

[0006] Furthermore, the elastic locking member includes a locking block, a first rod, and a first elastic element. The locking block is close to the mounting hole, the first rod is slidably inserted into the impact seat, and the first elastic element is sleeved on the first rod.

[0007] In the above technical solution, the locking block, the first rod and the first elastic element cooperate to enable the locking block to automatically lock into the annular groove when the pin is inserted, and to maintain the locking state under the action of the first elastic element, thereby enhancing the reliability of the connection. The structure is simple and the operation is reliable.

[0008] Furthermore, the unlocking component includes a push block, a second rod, and a second elastic element. The push block is close to the mounting hole, the second rod is slidably inserted through the impact seat and extends outward from the impact seat, and the second elastic element is sleeved on the second rod.

[0009] In the above technical solution, the unlocking component achieves radial sliding function through the combination of push block, second rod and second elastic element. The second rod extends out of the impact seat to facilitate force application, and the second elastic element realizes the automatic reset of push block after unlocking. The unlocking process is convenient and improves the disassembly and assembly experience.

[0010] Furthermore, the card block is provided with a first inclined surface, and the push block is provided with a second inclined surface. When the push block approaches the mounting hole, the second inclined surface pushes against the first inclined surface to drive the card block to move away from the mounting hole.

[0011] In the above technical solution, by setting a first inclined surface on the card block and a second inclined surface on the push block, the second inclined surface pushes against the first inclined surface, thereby achieving a smooth drive for the card block to move out of the annular groove, making the separation action more controllable and smooth.

[0012] Furthermore, the end of the second rod away from the push block is provided with a pressing part.

[0013] In the above technical solution, a pressing part is provided at the end of the second rod, which makes it convenient for the user to apply force and facilitates operation.

[0014] Furthermore, the side of the card block facing away from the probe is formed as an inclined surface to facilitate the insertion of the pin.

[0015] In the above technical solution, setting the upper end face of the card block as an inclined surface can avoid interference with the insertion of the pin and facilitate the pin's insertion into the mounting hole.

[0016] Furthermore, operating levers are symmetrically arranged on both sides of the drop hammer in the radial direction.

[0017] In the above technical solution, operating levers are symmetrically arranged on both sides of the drop hammer to facilitate the user's application of force and improve the stability and controllability of operating the drop hammer.

[0018] Furthermore, a limiting seat is provided at the end of the guide rod away from the pin.

[0019] In the above technical solution, a limiting seat is set at the end of the guide rod away from the pin, which can limit the maximum displacement of the falling hammer and ensure operational safety and consistency.

[0020] Compared with existing technologies, the advantages of this invention are as follows: The guide rod and the probe rod are each equipped with a pin and a mounting hole. During assembly, the pin can be inserted into the mounting hole, and the elastic locking component automatically engages with the annular groove under elastic force, thus achieving a quick connection between the guide rod and the impact seat without the need for tightening. When separation is required, pressing the unlocking component allows it to slide radially along the impact seat, thereby separating the elastic locking component from the annular groove. The operation is simple and convenient, effectively improving disassembly efficiency and enhancing operational convenience and efficiency while ensuring a stable connection.

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0026] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0027] Please refer to Figures 1 to 3 In a preferred embodiment, the lightweight, power penetrometer of this invention, which can be quickly disassembled and assembled, mainly includes a guide rod 1, a penetrometer rod 2, a penetrometer probe 3, and a drop hammer 4. One end of the penetrometer rod 2 is provided with an impact seat 5, and the other end of the penetrometer rod 2 is connected to the penetrometer probe 3. The drop hammer 4 is sleeved on the guide rod 1 and can slide along it. The impact seat 5 is provided with a mounting hole 53, and the outer periphery of the mounting hole 53 is provided with an elastic locking member 51 and an unlocking component 52. One end of the guide rod 1 is provided with a pin 11, and the pin 11 is provided with an annular groove 12. When the pin 11 is inserted into the mounting hole 53, the elastic locking member 51 extends into the annular groove 12, and the unlocking component 52 is configured to slide radially along the impact seat 5, so that the elastic locking member 51 separates from the annular groove 12.

[0028] For example, the drop hammer 4 has a through hole in the middle, through which the guide rod 1 can pass, allowing the drop hammer 4 to slide along the axial direction of the guide rod 1. The probe 3 is formed in a conical shape and can be integrally formed with the probe rod 2. The diameter of the impact seat 5 is larger than the diameter of the main body of the probe rod 2. When the probe rod 2 is connected to the guide rod 1, the drop hammer 4 can freely fall and impact the impact seat 5, thereby allowing the probe 3 to extend into the ground to be tested.

[0029] The guide rod 1 and the probe rod 2 are respectively provided with a pin 11 and a mounting hole 53. The diameter of the pin 11 is preferably matched with the inner diameter of the mounting hole 53 to improve the stability after assembly. During assembly, the pin 11 can be inserted into the mounting hole 53, and the elastic locking member 51 automatically engages with the annular groove 12 under the action of elastic force, thereby realizing the quick connection between the guide rod 1 and the impact seat 5 without the need for screwing. When separation is required, the unlocking component 52 is pressed to slide it radially along the impact seat 5, thereby driving the elastic locking member 51 to separate from the annular groove 12. The operation is simple and convenient, effectively improving the disassembly efficiency and enhancing the convenience and efficiency of operation while ensuring a stable connection.

[0030] Please refer to Figure 2 The elastic locking component 51 includes a locking block 511, a first rod 512, and a first elastic element 513. The locking block 511 is located near the mounting hole 53. The first rod 512 is slidably inserted into the impact seat 5, and the first elastic element 513 is sleeved on the first rod 512. For example, one end of the first rod 512 is slidably connected to the impact seat 5, and the other end is connected to the locking block 511. The first elastic element 513 can be a spring, compressed between the locking block 511 and the inner wall of the impact seat 5. Through the cooperation of the locking block 511, the first rod 512, and the first elastic element 513, the locking block 511 can automatically engage with the annular groove 12 when the pin 11 is inserted, and maintain the engaged state under the action of the first elastic element 513, enhancing the reliability of the connection. The structure is simple and the operation is reliable.

[0031] The unlocking component 52 includes a push block 521, a second rod 522, and a second elastic element 523. The push block 521 is located near the mounting hole 53. The second rod 522 is slidably inserted through the impact seat 5 and extends beyond the outside of the impact seat 5. The second elastic element 523 is sleeved on the second rod 522. For example, one end of the second rod 522 is slidably connected to the impact seat 5, and the other end is connected to the push block 521. The second elastic element 523 can be a spring, compressed between the push block 521 and the inner wall of the impact seat 5. The unlocking component 52 achieves radial sliding function through the combination of the push block 521, the second rod 522, and the second elastic element 523. The second rod 522 extends beyond the impact seat 5 for easy force application, and the second elastic element 523 enables the push block 521 to automatically reset after unlocking. The unlocking process is convenient and improves the disassembly and assembly experience.

[0032] The locking block 511 has a first inclined surface 514, and the push block 521 has a second inclined surface 524. When the push block 521 approaches the mounting hole 53, the second inclined surface 524 pushes against the first inclined surface 514, thereby driving the locking block 511 to move away from the mounting hole 53. By setting the first inclined surface 514 on the locking block 511 and the second inclined surface 524 on the push block 521, and by using the second inclined surface 524 to push against the first inclined surface 514, the locking block 511 can be smoothly driven out of the annular groove 12, making the separation action more controllable and smooth.

[0033] The second rod 522 has a pressing part 525 at the end away from the push block 521. The pressing part 525 at the end of the second rod 522 makes it convenient for the user to apply force and facilitates operation.

[0034] In this embodiment, the side of the locking block 511 facing away from the probe 3 is formed as an inclined surface to facilitate the insertion of the pin 11. Setting the upper end surface of the locking block 511 as an inclined surface can avoid interference with the insertion of the pin 11 and facilitate the insertion of the pin 11 into the mounting hole 53.

[0035] Operating levers 41 are symmetrically arranged on both sides of the drop hammer 4 in the radial direction. The symmetrical arrangement of operating levers 41 on both sides of the drop hammer 4 facilitates the user's application of force and improves the stability and controllability of operating the drop hammer 4.

[0036] A limiting seat 13 is provided at the end of the guide rod 1 away from the pin 11. The diameter of the limiting seat 13 is larger than the diameter of the guide rod 1. In this embodiment, the limiting seat 13 can be integrally formed with the guide rod 1. By providing the limiting seat 13 at the end of the guide rod 1 away from the pin 11, the maximum displacement of the drop hammer 4 can be limited, ensuring operational safety and consistency.
