Description

Technical Field

[0001] This utility model relates to the field of engineering surveying technology, and more specifically, it relates to a fixed-point marking device for engineering surveying. Background Technology

[0002] In engineering surveying, it is often necessary to set markers on the ground to determine specific locations and coordinates. To ensure the accuracy and stability of the measurement, the markers need to be precisely fixed in the designated locations.

[0003] However, existing technical solutions for fixing marker poles are usually cumbersome, requiring a lot of time and effort to install, and often making it difficult to achieve quick and stable fixing. Especially in complex ground environments, it is not easy to ensure the stability of the marker pole fixing, which may cause the marker position to shift, thus affecting the accuracy of subsequent measurements.

[0004] With the continuous development of engineering projects, especially in the field of high-precision measurement, the demand for fixed-point marking devices is increasing. Traditional marking rod designs have failed to fully consider the issues of quick disassembly and convenient carrying. In some scenarios where the marking position needs to be frequently adjusted or changed, the existing technical solutions are particularly inconvenient. Traditional fixing methods are not only cumbersome, but also require many operating steps when disassembling, which wastes time and reduces work efficiency. Utility Model Content

[0006] In view of the problems existing in the prior art, this utility model provides a fixed-point marking device for engineering measurement to solve the technical problems mentioned in the background art.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a fixed-point marking device for engineering surveying, comprising a marking rod, the bottom end of which is provided with a ground-fixing mechanism, the ground-fixing mechanism comprising a fixed rod, an inclined groove, a conical sleeve, a push rod, an insert rod, and an abutment block, the fixed rod being disposed at the bottom end of the marking rod, the inclined groove being provided with multiple sets distributed on the outer wall of the fixed rod, the conical sleeve being inserted into the outer wall of the fixed rod, the insert rod being provided with multiple sets sliding on the outer wall of the conical sleeve, the insert rod being provided with multiple sets rotatably mounted on the outer wall of the insert sleeve, the abutment block being fixed at the bottom end of multiple sets of push rods and abutting against the outer wall of the inclined groove, a quick-locking mechanism being provided between the fixed rod and the marking rod, the quick-locking mechanism comprising a locking sleeve, an outer sleeve, a slider, a locking plate, a locking groove, and a limiting mechanism, the locking sleeve being fixedly connected to the fixed rod, the outer sleeve being fixed to the top surface of the conical sleeve, the slider being provided with multiple sets sliding on the outer wall of the locking sleeve, the locking plate being fixed to the top of multiple sets of sliders, and the locking groove being provided with multiple sets distributed on the inner wall of the outer sleeve.

[0009] The present invention is further configured such that the limiting mechanism includes a rotating sleeve, a connecting rod, a screw, a push block, and an abutment plate. The rotating sleeve rotates on the top surface of the snap-fit ​​sleeve and is fixedly connected to the marking rod. The connecting rod rotates inside the snap-fit ​​sleeve and is fixedly connected to the rotating sleeve. The screw is fixed at the bottom end of the connecting rod and is rotatably connected to the inner wall of the snap-fit ​​sleeve. The push block is threadedly connected to the outer wall of the screw. The abutment plate is provided with multiple sets, which are respectively fixed at the bottom ends of multiple sets of sliders.

[0010] This invention is further configured such that a contraction spring is connected between the inner wall of each of the multiple sets of insertion rods and the outer wall of the cone sleeve. This configuration effectively increases the elastic connection between the insertion rod and the cone sleeve, allowing the insertion rod to automatically adjust its contact force with the soil after insertion, thereby enhancing the stability and anti-disturbance capability of the entire ground-fixing structure and improving the adaptability of the equipment in complex environments.

[0011] This invention is further characterized in that the outer sides of the multiple sets of push rods and abutment blocks are all provided with rounded corners. This design can reduce the damage to the surrounding structure during the contact process between the push rods and abutment blocks. At the same time, the rounded corner structure can transmit force more smoothly, avoiding damage caused by excessive friction or impact, and extending the service life of the device.

[0012] This invention is further configured such that a push spring is connected between the top surface of each of the multiple sets of abutment blocks and the inner wall of the fixing sleeve. The push spring allows the abutment blocks to generate a certain elastic feedback during operation, ensuring that the abutment blocks are always in a suitable working position, improving the stability of the structure, mitigating external impacts, and ensuring the reliability of the equipment during long-term use.

[0013] The present invention is further configured such that a positioning groove is provided on the outer wall of the fixing rod, and a positioning block is provided on the inner wall of the cone sleeve. Multiple sets of positioning grooves and positioning blocks are provided and slidably connected. This configuration ensures precise positioning between the fixing rod and the cone sleeve through the sliding cooperation of the positioning grooves and positioning blocks, preventing the marking rod from shifting or loosening during use, and improving the accuracy and reliability of the ground fixing mechanism.

[0014] This invention is further configured such that a limiting rod is provided inside the snap-fit ​​sleeve, and multiple sets of the limiting rod are provided and slidably connected to the push block. The sliding cooperation between the limiting rod and the push block makes the locking and unlocking of the marking rod more stable, avoiding excessive rotation or jamming, ensuring the flexibility and efficiency of the quick-locking mechanism, and improving the convenience of equipment disassembly.

[0015] This invention is further configured such that a return spring is connected between the inner wall of each of the multiple sets of card plates and the outer wall of the card sleeve. The return spring ensures that the card plate automatically returns to its initial position after disengagement, guaranteeing that the quick-release mechanism can quickly reset after each use, avoiding poor engagement, and improving operational convenience and equipment durability.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides a fixed-point marking device for engineering surveying, which has the following beneficial effects:

[0018] 1. By setting up a ground-fixing mechanism, the marker pole can be quickly and stably fixed to the ground during actual measurement operations. The cooperation between the inclined groove, the abutment block, the push rod, and the insertion rod allows the insertion rod to form a multi-point support structure after being inserted into the soil, thereby enhancing the device's adaptability and pull-out resistance in complex terrain. Simultaneously, the elastic element enables rapid repositioning during disassembly, improving operational efficiency and meeting the requirements for efficient installation and disassembly during the measurement process.

[0019] 2. The quick-release mechanism enables rapid connection and separation between the marker rod and the ground fixture. The cooperation between the slider, the locking plate, and the locking slot ensures the firmness of the connection process. The locking structure can be quickly disengaged during disassembly through the action of the return spring, reducing the dependence on tools and improving the convenience of on-site operation and the stability of repeated use. It is especially suitable for working conditions where measurement points are frequently changed.

[0020] 3. The introduction of the limit mechanism further enhances the controllability and stability of the structural operation. By rotating the structure to drive the connecting parts and the screw drive, precise pushing control of the push block and the abutment plate is achieved, allowing the slider to switch smoothly between locking and releasing. At the same time, the sliding cooperation of the limit component ensures smooth and continuous operation, thereby improving the reliability and safety of the entire fixing process and effectively avoiding measurement errors or equipment detachment caused by loose connections.

[0030] Please see Figures 1-5 A point marking device for engineering surveying includes a marking rod 1. A ground-fixing mechanism is provided at the bottom end of the marking rod 1. The ground-fixing mechanism includes a fixed rod 2, an inclined groove 3, a conical sleeve 4, a push rod 5, an insert rod 6, and an abutment block 7. The fixed rod 2 is located at the bottom end of the marking rod 1. Multiple sets of inclined grooves 3 are distributed on the outer wall of the fixed rod 2. The conical sleeve 4 is inserted into the outer wall of the fixed rod 2. Multiple sets of insert rods 6 slide on the outer wall of the conical sleeve 4. Multiple sets of insert rods 6 are rotatably mounted on the outer wall of the insert sleeve. The abutment block 7 is fixed... The bottom of multiple sets of push rods 5 is fixed and abuts against the outer wall of the inclined groove 3. A quick-locking mechanism is provided between the fixed rod 2 and the marking rod 1. The quick-locking mechanism includes a locking sleeve 8, an outer sleeve 9, a slider 10, a locking plate 11, a locking groove 12 and a limiting mechanism. The locking sleeve 8 is fixedly connected to the fixed rod 2. The outer sleeve 9 is fixed on the top surface of the conical sleeve 4. Multiple sets of sliders 10 are provided to slide on the outer wall of the locking sleeve 8. The locking plate 11 is fixed on the top of multiple sets of sliders 10. Multiple sets of locking grooves 12 are provided on the inner wall of the outer sleeve 9.

[0031] The limiting mechanism includes a rotating sleeve 13, a connecting rod 14, a screw 15, a push block 16, and an abutment plate 17. The rotating sleeve 13 rotates on the top surface of the snap-fit ​​sleeve 8 and is fixedly connected to the marking rod 1. The connecting rod 14 rotates inside the snap-fit ​​sleeve 8 and is fixedly connected to the rotating sleeve 13. The screw 15 is fixed to the bottom end of the connecting rod 14 and is rotatably connected to the inner wall of the snap-fit ​​sleeve 8. The push block 16 is threadedly connected to the outer wall of the screw 15. The abutment plate 17 is provided with multiple sets that are respectively fixed to the bottom ends of multiple sets of sliders 10.

[0032] Each set of insertion rods 6 has a contraction spring 18 connected between its inner wall and the outer wall of the cone sleeve 4. The principle is that the contraction spring 18 provides elastic support, allowing the cone sleeve 4 to adapt to different soil conditions and maintain the stability of the insertion rods 6 when inserted.

[0033] The outer sides of multiple sets of push rods 5 and abutment blocks 7 are all provided with rounded corners. The principle is to use the rounded corner structure to reduce friction and stress concentration between push rods 5 and abutment blocks 7, improve assembly smoothness and reduce wear.

[0034] Each of the multiple sets of abutment blocks 7 has a push spring 19 connected between its top surface and the inner wall of the fixed sleeve. The principle is that the push spring 19 provides an upward elastic force, causing the abutment block 7 to always fit against the inside of the fixed sleeve, thereby enhancing the shock resistance and stability of the device.

[0035] The outer wall of the fixed rod 2 is provided with a positioning groove 20, and the inner wall of the cone sleeve 4 is provided with a positioning block 21. Multiple sets of positioning grooves 20 and positioning blocks 21 are provided and are slidably connected. The principle is that the positioning grooves 20 and positioning blocks 21 cooperate to achieve precise positioning and guidance between the fixed rod 2 and the cone sleeve 4, ensuring the positional accuracy and stability of the device during installation.

[0036] The snap-fit ​​sleeve 8 is equipped with a limiting rod 22. Multiple sets of limiting rods 22 are provided and are slidably connected to the push block 16. The principle is that the limiting rod 22 and the push block 16 form a sliding constraint relationship, which can control the movement range of the push block 16 and realize the limiting and guiding functions when the marking rod is snapped.

[0037] Each set of card plates 11 has a return spring 23 connected between its inner wall and the outer wall of the card sleeve 8. The principle is that the return spring 23 can automatically restore the card plate 11 to its initial position after the device is disassembled, which facilitates operation again and improves the reusability of the quick-card mechanism.

[0038] In this embodiment, when it is necessary to fix the marker rod 1, firstly, the conical sleeve 4 is inserted into the bottom soil, and then the fixing rod 2 is inserted into the conical sleeve 4. Multiple sets of positioning blocks 21 are positioned and inserted into the positioning groove 20. Multiple sets of inclined grooves 3 push multiple sets of abutment blocks 7 and push rods 5 through the inner wall of multiple sets of inclined grooves 3, so that the top of multiple sets of push rods 5 pushes the insertion rod 6. Multiple sets of insertion rods 6 rotate and extend into the soil. Then, the snap-fit ​​sleeve 8 is inserted into the outer sleeve 9. Rotating the rotating sleeve 13 drives the connecting rod 14 to make the screw 15 rotate and engage with the push sleeve threadedly, so that the push block 16 slides along the screw 15 and multiple sets of limiting rods 22 and pushes multiple sets of abutment plates 17. Multiple sets of abutment plates 17 push the slider 10 so that the snap plate 11 is snapped into the snap groove 12 and stretches multiple sets of return springs 23, thus completing the fixation of the marker rod 1.

[0039] More specifically, when it is necessary to disassemble the marking rod 1, the reverse rotating sleeve 13 drives the screw 15 to rotate through the connecting rod 14, so that the screw 15 drives the push block 16 to release the contact with the multiple sets of abutment plates 17. The multiple sets of reset springs 23 pull the clamp plate 11 out of the slot 12, releasing the fixation between the clamp sleeve 8 and the outer sleeve 9. Then, the fixing rod 2 is pulled out of the cone sleeve 4, so that the multiple sets of inclined grooves 3 release the contact with the multiple sets of abutment blocks 7. The multiple sets of push springs 19 push the abutment blocks 7 to pull the push rod 5 to release the contact with the multiple sets of insertion rods 6, so that the multiple sets of insertion rods 6 are released from the limit. The cone sleeve 4 is pulled out of the bottom surface, and the insertion rods 6 are reset by the multiple sets of contraction springs 18.

[0040] In summary, when the overall equipment is in use or operation: when it is necessary to fix the marking rod 1, first insert the cone sleeve 4 into the bottom soil, then insert the fixing rod 2 into the cone sleeve 4, and use multiple sets of positioning blocks 21 to position and insert into the positioning groove 20. Use the inner wall of multiple sets of inclined grooves 3 to push multiple sets of abutment blocks 7 and push rods 5, so that the top of multiple sets of push rods 5 pushes the insertion rod 6, and multiple sets of insertion rods 6 rotate and extend into the soil. Then, the snap-fit ​​sleeve 8 is inserted into the outer sleeve 9. Rotate the rotating sleeve 13 to drive the connecting rod 14 to make the screw 15 rotate and engage with the push sleeve. This causes the push block 16 to slide along the screw 15 and multiple sets of limit rods 22 and push multiple sets of abutment plates 17. The multiple sets of abutment plates 17 push the slider 10 to make the snap plate 11 snap into the snap groove 12 and stretch the multiple sets of return springs 23, thus completing the fixation of the marking rod 1.

[0041] When it is necessary to disassemble the marking rod 1, the reverse rotating sleeve 13 drives the screw 15 to rotate through the connecting rod 14, so that the screw 15 drives the push block 16 to release the contact with the multiple sets of abutment plates 17. The multiple sets of reset springs 23 pull the clamp plate 11 out of the slot 12, releasing the fixation between the clamp sleeve 8 and the outer sleeve 9. Then, the fixing rod 2 is pulled out of the cone sleeve 4, so that the multiple sets of inclined grooves 3 release the contact with the multiple sets of abutment blocks 7. The multiple sets of push springs 19 push the abutment block 7 to pull the push rod 5 to release the contact with the multiple sets of insertion rods 6, so that the multiple sets of insertion rods 6 are released from the limit. The cone sleeve 4 is pulled out of the bottom surface, and the insertion rods 6 are reset by the multiple sets of contraction springs 18.

For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
