Abstract
Description
Technical Field
[0001] This utility model relates to the field of soil and water conservation technology, and in particular to a safety rod insertion device. Background Technology
[0002] Pipettes are a method of soil and water monitoring. They involve inserting several stakes into the ground at regular intervals, marking the points on the stakes at the soil surface as initial elevations. After rainfall, the amount of soil erosion is observed by measuring the thickness of the subsidence. While graduated lines are typically used for marking to facilitate measurement, friction between the stakes and the soil during insertion causes the graduated lines to become blurred, affecting the measurement accuracy. Utility Model Content
[0003] The purpose of this invention is to solve the problem in the existing technology that causes friction between the scale lines on the insertion device and the soil, resulting in blurred scale lines and affecting measurement, and to propose a safe insertion device.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] Design a safety insertion device, including an insertion rod, a connecting ring fixedly connected to the insertion rod, a limit sleeve fixedly connected to the connecting ring, a scale inside the limit sleeve, a striking part connected to the upper end of the insertion rod through an adjustment mechanism, and the distance from the lower end of the insertion rod to the upper surface of the striking part being equal to the length of the scale.
[0006] Preferably, a miniature bubble level is provided at the upper end of the connecting ring.
[0007] Preferably, the adjusting mechanism includes a movable block that abuts against the insert rod. A bolt is rotatably connected to the movable block via a bearing. A fixing block is threaded through the bolt and fixedly connected to the insert rod. The movable block is connected to the striking part via a connecting mechanism.
[0008] Preferably, the connecting mechanism includes an inclined surface, the movable block is provided with an inclined surface, a T-shaped groove is formed on the inclined surface, a T-shaped slider is slidably disposed in the T-shaped groove, a connecting block is fixedly connected to the T-shaped slider, and the connecting block is fixedly connected to the striking part.
[0009] Preferably, the bearing is a thrust ball bearing.
[0010] Preferably, a plurality of limiting posts are fixedly connected to the striking part, and a positioning sleeve is fitted over each of the plurality of limiting posts, and the plurality of positioning sleeves are fixedly connected to the insert rod.
[0011] Preferably, both ends of the scale are fixedly connected to a stop block.
[0012] The present invention proposes a safety insertion device, which has the following advantages: by inserting the insertion rod into the ground, the upper end of the scale is made higher than the striking part to measure the insertion depth. After the soil is impacted, the scale descends to measure. Since the scale is not inserted into the soil, wear is avoided. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0019] Example 1: Refer to Figure 1-3A safety insertion device includes an insertion rod 1, a connecting ring 2 fixedly connected to the insertion rod 1, a limiting sleeve 3 fixedly connected to the connecting ring 2, a scale 4 provided inside the limiting sleeve 3, and a transparent film provided on the scale 4 to prevent the limiting sleeve 3 from affecting the scale 4 when the scale 4 moves relative to the limiting sleeve 3. The upper end of the insertion rod 1 is connected to a striking part 6 through an adjustment mechanism. By inserting the insertion rod 1 into the ground, the scale 4 will not enter the soil, so that the scale 4 is higher than the striking part 6. Since the distance from the lower end of the insertion rod 1 to the upper surface of the striking part 6 is equal to the length of the scale 4, the upper end of the scale 4 will be higher than the striking part 6 to measure the insertion depth. After the soil is impacted, the scale 4 descends to measure. Since the scale 4 is not inserted into the soil, wear is avoided.
[0020] The upper end of the connecting ring 2 is equipped with a miniature bubble level so that it can be inserted vertically into the ground.
[0021] Example 2: In Example 1, when inserting the device into the ground, a heavy object is typically used to strike the striking part 6. Prolonged striking can cause deformation of the striking part 6, leading to a decrease in height and potentially causing the overall length of the device to differ from the length of the scale 4, thus affecting the accuracy of the measurement. (Refer to...) Figure 1-4 In another preferred embodiment of this utility model, based on embodiment 1, the adjustment mechanism includes a movable block 7, which abuts against the insert rod 1. A bolt 8 is rotatably connected to the movable block 7 via a bearing, which is a thrust ball bearing. A fixed block 14 is threaded through the bolt 8 and fixedly connected to the insert rod 1. The movable block 7 is connected to the striking part 6 via a connecting mechanism. By rotating the bolt 8, the movable block 7 will move, and the movable block 7 will adjust the position of the T-shaped slider 13 in the T-shaped groove 12, thereby adjusting the height of the striking part 6 and ensuring that the length of the entire device is equal to the length of the scale 4.
[0022] The connecting mechanism includes an inclined surface. The inclined surface is provided on the moving block 7. The inclined surface helps to decompose the hammering force and prevents the direct action on the bolt 8, which could damage the threaded connection. A T-shaped groove 12 is provided on the inclined surface. A T-shaped slider 13 is slidably arranged in the T-shaped groove 12. A connecting block 11 is fixedly connected to the T-shaped slider 13. The connecting block 11 is fixedly connected to the striking part 6. The T-shaped slider 13 and the T-shaped groove 12 are used to connect the striking part 6 and the moving block 7.
[0023] Multiple limiting posts 9 are fixedly connected to the striking part 6. Each of the multiple limiting posts 9 is fitted with a positioning sleeve 10. The multiple positioning sleeves 10 are fixedly connected to the insert rod 1. The positioning sleeves 10 and the limiting posts 9 are used to horizontally limit the striking part 6 and prevent it from moving in the horizontal direction.
[0024] Example 3: Reference Figure 1-4 As another preferred embodiment of this utility model, based on embodiment 2, both ends of the scale 4 are fixedly connected with stop blocks 5, which helps to prevent the scale 4 from disengaging from the limiting sleeve 3.
[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
