Technical Field

[0001] This utility model relates to the field of bolt manufacturing technology, and more specifically, to a device for galvanizing the surface of anchor bolts. Background Technology

[0002] Bolts are mechanical parts, cylindrical threaded fasteners that are used with nuts. They consist of a head and a shank (a cylinder with external threads). They need to be used with nuts. When processing bolts, galvanizing is usually done to improve their service life.

[0003] A search revealed a prior art device for hot-dip galvanizing bolts, patent publication number CN222100105U. The specification states that by providing an anti-splashing component, zinc liquid splashing can be prevented during the immersion and spin-drying process of the bolts. Furthermore, the bolts can be cooled during the spin-drying process to shorten the drying time.

[0004] However, in actual use, since the bolts are placed directly inside the placement frame, the long-term contact area between the bolts and the placement frame, as well as between the bolts themselves, cannot be effectively galvanized, resulting in low galvanization quality and thus low economic efficiency. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a zinc plating device for anchor bolts, so as to solve the problem that in the prior art, the long-term contact parts between the bolt and the placement frame and the bolt cannot be effectively zinc-plated, resulting in low zinc plating quality and low economic efficiency.

[0006] To solve the above technical problems, this utility model provides the following technical solution: a galvanizing device for anchor bolts, including a galvanizing barrel, a placement frame slidably connected inside the galvanizing barrel, a plurality of placement blocks fixedly connected outside the placement frame, a plurality of placement grooves opened at the top of the galvanizing barrel, the placement blocks slidably connected inside the placement grooves, and a connecting rod detachably connected to the bottom of the placement blocks.

[0007] The placement block has a slot inside, and two limiting rings are fixedly connected to the inner wall of the slot. Multiple protrusions are fixedly connected to the inner side of the limiting rings. An insert block is inserted into the slot. The bottom end of the insert block is fixedly connected to the top end of the connecting rod. Two limiting grooves are opened on the outer periphery of the insert block, and multiple grooves are opened on the inner wall of the limiting grooves.

[0008] The placement groove has a sliding groove on the lower inner wall, the sliding groove has a connecting groove on the lower inner wall, the bottom end of the connecting rod is fixedly connected to an extrusion plate, the bottom end of the extrusion plate is fixedly connected to a pull rod, the pull rod is sleeved with an elastic element, the bottom end of the pull rod is fixedly connected to a pull block, and the pull block is fixedly connected to a pull ring.

[0009] The insert is an arc-shaped block structure that slides against the inner side of the limiting ring, and the limiting ring is in contact with the interior of the corresponding limiting groove.

[0010] The protrusion slides against the outside of the insert block, and the protrusion fits into the inside of the corresponding groove.

[0011] The connecting rod is slidably connected inside the groove, and the extrusion plate is slidably connected inside the groove.

[0012] One end of the elastic element is fixedly connected to the extrusion sheet, and the other end of the elastic element is fixedly connected to the inner wall of the groove.

[0013] One side of the pull rod is slidably connected to the inside of the slide groove, and the other side of the pull rod is slidably connected to the inside of the connecting groove. The pull block is slidably connected to the inside of the connecting groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In the above solution, by moving the placement frame up and down, the bolts inside the placement frame can be moved, so that the bolts will not come into contact with other objects for a long time, resulting in higher uniformity of galvanization and thus higher galvanization quality, which in turn makes the use more economical.

[0023] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0024] Example 1: Please refer to Figures 1 to 5 This utility model provides a technical solution: a galvanizing device for anchor bolts, including a galvanizing bucket 1, a placement frame 2 slidably connected inside the galvanizing bucket 1 for holding anchor bolts, a plurality of placement blocks 3 fixedly connected to the outside of the placement frame 2, a plurality of placement grooves 4 opened at the top of the galvanizing bucket 1, the placement blocks 3 slidably connected inside the placement grooves 4, the placement grooves 4 limit the placement blocks 3 so that the placement blocks 3 can slide smoothly, and a connecting rod 5 is detachably connected to the bottom of the placement blocks 3, the connecting rod 5 is used to push the placement blocks 3 up and down and can be easily separated from the connecting rod 5, thereby allowing the anchor bolts inside the placement frame 2 to be poured out.

[0025] When it is necessary to shake the anchor bolts, the anchor bolts can be shaken by shaking the placement frame 2 up and down. This prevents the bolts from coming into contact with other objects for a long time, resulting in higher uniformity of galvanization and thus higher galvanization quality, which in turn makes the use more economical.

[0026] Example 2: Based on Example 1, in order to ensure the connection stability between the placement block 3 and the connecting rod 5 and to facilitate the disassembly of the placement block 3, a slot 13 is provided inside the placement block 3. Two limiting rings 14 are fixedly connected to the inner wall of the slot 13. Multiple protrusions 15 are fixedly connected to the inner side of the limiting rings 14. An insert block 16 is inserted into the slot 13. The insert block 16 has an arc-shaped block structure, so that it can slide into the inside of the slot 13, deform, and slide against the inner side of the limiting rings 14. The protrusion 15 slides against the outside of the insertion block 16, allowing the insertion block 16 to push the limiting ring 14 and the protrusion 15 to deform. The bottom end of the insertion block 16 is fixedly connected to the top end of the connecting rod 5. Two limiting grooves 17 are opened on the outer periphery of the insertion block 16. The limiting ring 14 fits into the inside of the corresponding limiting groove 17, allowing the insertion block 16 to be limited. Multiple grooves 18 are opened on the inner wall of the limiting groove 17. The protrusion 15 fits into the inside of the corresponding groove 18, allowing the insertion block 16 to be limited a second time.

[0027] When it is necessary to install the placement block 3, the placement block 3 is slid into the placement groove 4, thereby allowing the placement block 3 to slide against the slot 13 and deform the slot 13. When the insertion block 16 slides into the slot 13, the insertion block 16 deforms by pressing the limiting ring 14 and the protrusion 15, and the insertion block 16 can perform a reset movement, allowing the insertion block 16 to fill the interior of the slot 13, thereby allowing the limiting ring 14 and the protrusion 15 to perform a reset movement, allowing the limiting ring 14 to fit into the interior of the limiting groove 17, and allowing the protrusion 15 to fit into the interior of the groove 18, thereby limiting the placement block 3. Conversely, it can be easily disassembled.

[0028] Example 3: Based on Example 2, to increase the shaking frequency, a sliding groove 6 is provided on the lower inner wall of the placement groove 4. The connecting rod 5 is slidably connected inside the sliding groove 6. The sliding groove 6 limits the connecting rod 5, allowing it to slide smoothly. A connecting groove 10 is provided on the lower inner wall of the sliding groove 6. An extrusion plate 7 is fixedly connected to the bottom end of the connecting rod 5. The extrusion plate 7 is slidably connected inside the sliding groove 6. The sliding groove 6 limits the extrusion plate 7, allowing it to slide smoothly. A pull rod 8 is fixedly connected to the bottom end of the extrusion plate 7. One side of the pull rod 8 is slidably connected inside the sliding groove 6, and the other side is slidably connected to... Inside the connecting groove 10, the sliding groove 6 and the connecting groove 10 limit the pull rod 8, allowing the pull rod 8 to slide stably. An elastic element 9 is sleeved on the outside of the pull rod 8. One end of the elastic element 9 is fixedly connected to the extrusion plate 7, and the other end of the elastic element 9 is fixedly connected to the inner wall of the sliding groove 6. A pull block 11 is fixedly connected to the bottom end of the pull rod 8. The pull block 11 is used to pull the pull rod 8 downward. The pull block 11 is slidably connected inside the connecting groove 10. The connecting groove 10 limits the pull block 11, allowing the pull block 11 to slide smoothly. A pull ring 12 is fixedly connected to the outside of the pull block 11. The pull ring 12 is used to pull multiple pull blocks 11 simultaneously.

[0029] When it is necessary to shake the placement frame 2, pull the pull ring 12 downwards, causing the pull ring 12 to pull multiple pull blocks 11 downwards. This causes the pull blocks 11 to pull the corresponding pull rod 8 downwards, which in turn causes the pull rod 8 to pull the compression plate 7 to compress the elastic element 9, causing it to deform. The compression plate 7 then pulls the placement block 3 downwards via the connecting rod 5. Subsequently, the pull ring 12 is released, allowing the elastic element 9 to return to its original position. This pushes the compression plate 7 upwards, which in turn pushes the connecting rod 5 upwards, which in turn pushes the placement block 3 upwards. As the elastic element 9 shakes up and down, the placement block 3 continues to move up and down, causing the placement frame 2 to continuously shake the bolt. Once the elastic element 9 stops, the above actions are repeated.

[0030] The working process of this utility model is as follows:

[0031] When galvanizing the anchor bolts is required, pulling the pull ring 12 upwards keeps the connecting rod 5 stable. The placement block 3 slides into the placement groove 4, causing it to slide against the slot 13 and deform. When the insertion block 16 slides into the slot 13, it deforms by pressing against the limiting ring 14 and the protrusion 15, allowing the insertion block 16 to return to its original position. This fills the slot 13, causing the limiting ring 14 and the protrusion 15 to return to their original position, fitting the limiting ring 14 into the limiting groove 17 and the protrusion 15 into the recess 18. This limits the placement block 3. Pulling the pull ring 12 downwards then moves multiple pull blocks 11 downwards. This causes the pull block 11 to pull the corresponding position of the pull rod 8 downward, which in turn causes the pull rod 8 to pull the extrusion plate 7 to compress the elastic element 9, causing it to deform. The extrusion plate 7 then pulls the placement block 3 downward via the connecting rod 5. Subsequently, the pull ring 12 is released, allowing the elastic element 9 to return to its original position. This, in turn, pushes the extrusion plate 7 upward, which in turn pushes the connecting rod 5 upward, which in turn pushes the placement block 3 upward. As the elastic element 9 swings up and down, the placement block 3 continues to move back and forth, causing the placement frame 2 to continuously shake the bolt. Once the elastic element 9 comes to a stop, the above actions are repeated. This prevents the bolt from coming into prolonged contact with other objects, resulting in higher uniformity of galvanization and thus higher galvanization quality, leading to greater economic efficiency in its use.
