Abstract
Description
Technical Field
[0001] This utility model relates to the field of acceptance rod technology, and in particular to a magnetic end acceptance rod. Background Technology
[0002] During the tunneling face cutting construction, measurements were taken according to the parameters of the construction center line, roadway center line, offset line, and waist line that were hung on site to ensure that the project quality met the regulations and standards.
[0003] The 3m acceptance pole used on site has a hook at the top end. It is usually hung on the top plate anchor net for measurement. However, due to the limitations of the support materials, sometimes the top plate at the measurement point is a steel strip, which cannot be used for hanging, so the applicable scope is small. Summary of the Invention
[0004] The purpose of this utility model is to solve the shortcomings of the existing technology where the top end of the acceptance rod is a hook, which is usually hung on the top plate anchor net for measurement. However, due to the limitation of the support material, sometimes the top plate at the measurement point is a steel strip, which cannot be used for hanging, resulting in a limited range of applications. Therefore, a magnetic end acceptance rod is proposed.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A magnetic end acceptance rod includes an acceptance rod body. The top of the acceptance rod body has two symmetrically arranged No. 2 circular holes. The inside of the acceptance rod body has two symmetrically arranged cavities. The two No. 2 circular holes are respectively located at the top of the two cavities and are connected to the cavities. End components for acceptance are slidably connected inside the two cavities.
[0007] The main body of the acceptance rod is provided with protective sleeves on both sides. A circular hole No. 1 is opened on the side of the two protective sleeves that are close to each other. A fixing component for fixing the end assembly is provided on one side of the protective sleeve.
[0008] In one possible design, the end assembly includes a second sliding block slidably connected inside one of the cavities, the bottom of the second sliding block being fixedly connected to the same second tension spring between the bottom of the second sliding block and the bottom inner wall of the cavity, and a hook being fixedly connected to the top of the second sliding block, the hook engaging with a first circular hole.
[0009] In one possible design, the end assembly further includes a first sliding block slidably connected inside another cavity, the bottom of the first sliding block being fixedly connected to the same first tension spring between the bottom of the first sliding block and the bottom inner wall of the cavity, and a connecting rod being fixedly connected to the top of the first sliding block, the top of the connecting rod slidingly passing through a second circular hole and being fixedly connected to a magnet.
[0010] In one possible design, two slots are provided on the side of the connecting rod and the hook that are far apart from each other.
[0011] In one possible design, the fixing component includes a plug rod fixedly connected to one side of the two protective sleeves that are close to each other. Each side of the two protective sleeves that are close to each other has a positioning groove. The plug rod and the positioning groove are centrally symmetrical. The plug rod engages with the positioning groove and the plug rod engages with the slot.
[0012] In one possible design, the main body of the inspection rod has strip-shaped holes on both sides. A vertical groove is formed on the inner wall of one side of the strip-shaped hole. A first horizontal groove and a second horizontal groove are formed on one side of the vertical groove. The first horizontal groove is located above the second horizontal groove. The depth of the second horizontal groove is less than the depth of the first horizontal groove. A strip-shaped rod is fixedly connected to the inner wall of one side of the protective sleeve. A limit block is fixedly connected to one end of the strip-shaped rod. The strip-shaped rod is used in conjunction with the strip-shaped hole. The limit block is used in conjunction with the first horizontal groove, the vertical groove, and the second horizontal groove.
[0013] In one possible design, a handle is fixedly fitted onto the outer wall of the main body of the inspection rod, and the handle is provided with multiple anti-slip textures.
[0014] In this application, during normal use, the two snap-fit protective sleeves can be pulled out laterally. At this time, the corresponding insert rod moves out from the inside of the positioning groove, which can release the snap-fit state between the two protective sleeves. At the same time, the limiting block and the strip rod move laterally inside the first horizontal groove. Under the action of gravity, the limiting block enters the inside of the second horizontal groove along the vertical groove, and the strip rod moves inside the strip hole. At this time, the connecting rod and the hook are both exposed.
[0015] When it is necessary to hang the hook on the anchor net or to attach the magnet to the steel strip, the hook and magnet can be pulled out as needed. After the hook and magnet are pulled out, the two protective sleeves can be brought closer together again. At this time, the limiting block is fully inserted into the interior of the second transverse groove, and the insertion rod is engaged with the corresponding slot, thereby fixing the hook and connecting rod. At the same time, the second tension spring and the first tension spring continuously exert tension on the second sliding block and the first sliding block, thereby increasing the friction between the insertion rod and the slot, ensuring the stability of the device, and preventing shaking during use.
[0016] Beneficial effects: 1. Convenient operation: Users can easily release the latch by pulling out the two snap-fit protective sleeves horizontally, making components such as hooks and magnets easy to use and store. This design not only simplifies the operation steps but also improves ease of use.
[0017] 2. Flexible applicability: The hooks and magnets can be flexibly extended according to actual needs, making them suitable for various scenarios, such as hanging on anchor nets or adhering to steel strips. This flexibility allows the device to meet different working environments and requirements, enhancing its practical value.
[0018] 3. Stable fixation: Through the interlocking of the plug rod and the slot, and the continuous tension of the spring on the sliding block, the device of this application can ensure the stability of the hook and connecting rod during use, preventing shaking or falling off, thereby improving safety and reliability.
[0019] 4. Innovative Structural Design: The clever combination of components such as limiting blocks, strip rods, the first horizontal groove, the vertical groove, and the second horizontal groove enables convenient opening and closing and secure fixation of the protective sleeve. This structural design is not only novel and unique but also improves the overall performance and durability of the device.
[0020] 5. Efficient space utilization: When not in use, the hooks and magnets can be stored inside the protective sleeve, saving space and preventing the loss or damage of parts. This design makes the device more compact and practical. Attached Figure Description

The two second circular holes 24 are respectively located at the top of the two cavities 21 and communicate with the cavities 21. End-of-line components for inspection are slidably connected inside the two cavities 21. The end-of-line components include a second sliding block 23 slidably connected inside one of the cavities 21, with the same second tension spring 22 fixedly connected between the bottom of the second sliding block 23 and the bottom inner wall of the cavity 21. A hook 4 is fixedly connected to the top of the second sliding block 23, and the hook 4 cooperates with a first circular hole 9. The end-of-line components also include a first sliding block 19 slidably connected inside the other cavity 21, with the bottom of the first sliding block 19 fixedly connected to the bottom inner wall of the cavity 21. The first sliding block 19 is connected to the same first tension spring 20. The top of the first sliding block 19 is fixedly connected to the connecting rod 12. The top of the connecting rod 12 slides through the second round hole 24 and is fixedly connected to the magnet 7. Two slots 8 are opened on the side of the connecting rod 12 and the hook 4 that are far apart from each other. When it is necessary to hang the hook 4 on the anchor net or to attract the magnet 7 to the steel strip, the hook 4 and the magnet 7 can be pulled out as needed. After the hook 4 and the magnet 7 are pulled out, the two protective sleeves 5 can be brought closer to each other again. At this time, the limiting block 17 is completely inserted into the interior of the second transverse groove 16, and the insertion rod 11 is engaged with the corresponding slot 8, thereby fixing the hook 4 and the connecting rod 12. At the same time, the second tension spring 22 and the first tension spring 20 continuously exert tension on the second sliding block 23 and the first sliding block 19, thereby increasing the friction between the insertion rod 11 and the slot 8, ensuring the stability of the device, and avoiding shaking during use.
[0030] The main body 1 of the inspection rod is provided with protective sleeves 5 on both sides. A circular hole 9 is opened on the side of each protective sleeve 5 that is close to each other. A fixing component for fixing the end assembly is provided on one side of each protective sleeve 5. The fixing component includes a rod 11 fixedly connected to the side of each protective sleeve 5 that is close to each other. A positioning groove 10 is opened on the side of each protective sleeve 5 that is close to each other. The rod 11 and the positioning groove 10 are centrally symmetrical. The rod 11 engages with the positioning groove 10 and the slot 8. The main body 1 of the inspection rod is provided with strip-shaped holes 6 on both sides. A vertical groove 15 is opened on the inner wall of one side of the strip-shaped hole 6. A first horizontal groove 13 and a second horizontal groove 16 are opened on one side of the vertical groove 15. The first horizontal groove 13 is located above the second horizontal groove 16. The depth of groove 16 is less than the depth of the first horizontal groove 13. A strip rod 18 is fixedly connected to the inner wall of one side of the protective sleeve 5. A limiting block 17 is fixedly connected to one end of the strip rod 18. The strip rod 18 is used in conjunction with the strip hole 6. The limiting block 17 is used in conjunction with the first horizontal groove 13, the vertical groove 15 and the second horizontal groove 16. The two locked protective sleeves 5 can be pulled out laterally. At this time, the corresponding insert rod 11 moves out from the inside of the positioning groove 10, which can release the jamming state between the two protective sleeves 5. At the same time, the limiting block 17 and the strip rod 18 move laterally inside the first horizontal groove 13. Under the action of gravity, the limiting block 17 enters the inside of the second horizontal groove 16 along the vertical groove 15. The strip rod 18 moves inside the strip hole 6. At this time, the connecting rod 12 and the hook 4 are both in the exposed state.
