Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a prefabricated support and hanger connection structure. Background Technology

[0002] In building construction, supports and hangers are key components for supporting, suspending, and fixing various pipeline systems. Their performance directly affects the safety and reliability of the building's electromechanical systems. Traditional supports and hangers are generally fixed by on-site welding, which results in low construction efficiency, large quality fluctuations, and safety hazards. To address this issue, the industry is gradually promoting prefabricated support and hanger technology. Current prefabricated supports and hangers can be connected through quick-release structures. However, most quick-release structures require moving the components to a preset fixed position to lock them in place. This forces construction workers to prepare various specifications of quick-release structures according to specific needs, increasing the workload of material management and construction preparation. During construction, construction workers need to select suitable quick-release structures, which can easily affect construction efficiency. Based on this, this application proposes a prefabricated support and hanger connection structure. Utility Model Content

[0003] This utility model provides a prefabricated support and hanger connection structure, which solves the problems of poor adaptability and low installation efficiency of quick-release structures that require moving components to a preset position as mentioned in the background art.

[0004] This utility model provides the following technical solution: a prefabricated support and hanger connection structure, including an insertion part and a locking part. The insertion part includes a vertical rod adapted to the mounting hole of the prefabricated support and hanger, a limiting plate connected to one end of the vertical rod, and a positioning block connected to the other end of the vertical rod. Limiting grooves are provided on both sides of the other end of the vertical rod. The locking part includes a hollow shell. A locking sleeve is connected to the inner cavity of the hollow shell through a first spring. The locking sleeve is movably connected to the inner cavity of the hollow shell. Limiting blocks are connected to both sides of the bottom end of the inner cavity of the locking sleeve through second springs. The limiting blocks are adapted to the limiting grooves. A positioning sleeve is movably connected to the top end of the inner cavity of the locking sleeve. The positioning sleeve is adapted to the limiting block.

[0005] Preferably, the outer diameter of the limiting plate is larger than the outer diameter of the upright, and the outer diameter of the positioning block is not larger than the outer diameter of the upright.

[0006] Preferably, both the hollow housing and the locking sleeve have through holes adapted to the upright in the middle of the bottom of their inner cavities. The hollow housing has a slot on one side, and a handle is movably connected to the inner cavity of the slot. One end of the handle extends to the outside of the hollow housing, and the other end of the handle is connected to the locking sleeve. Anti-slip pads are provided on both sides of the bottom end of the slot.

[0007] Preferably, the outer ring of the hollow shell is movably connected to a pull ring, and the two sides of the bottom of the inner cavity of the hollow shell are provided with fixing grooves. The fixing grooves are adapted to the limiting blocks, and the inner cavity of the fixing grooves is movably connected to a pull rope. One end of the pull rope is connected to the limiting block, and the other end of the pull rope passes through the hollow shell and is connected to the pull ring. The pull rope is movably connected to the hollow shell.

[0008] Preferably, a guide groove is provided at the top of the inner cavity of the locking sleeve, and a guide rod is movably connected in the guide groove, the guide rod being connected to the outer wall of the positioning sleeve.

[0009] Preferably, the bottom of the limiting block is provided with a sliding groove, and a slider is movably connected in the sliding groove. The slider is connected to the bottom of the inner cavity of the locking sleeve. The limiting block is connected to the slider through a second spring. The limiting block is L-shaped. The outer wall of the vertical end of the limiting block is adapted to the inner wall of the locking sleeve, and the inner wall of the vertical end of the limiting block is adapted to the outer wall of the positioning sleeve. When the end of the limiting block away from the positioning sleeve is tightly fitted with the inner wall of the fixing groove, a positioning groove adapted to the positioning block is formed between the two limiting blocks.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. The prefabricated support and hanger connection structure uses a limiting block to restrict the insertion part, so that the insertion part and the lock core form a whole. The rebound force of the first spring is used as the driving force to drive the insertion part, so that the insertion part and the prefabricated support and hanger components can be quickly and tightly fitted, realizing the rapid connection of the prefabricated support and hanger components, reducing manual operation steps, and improving the assembly efficiency of the prefabricated support and hanger.

[0012] 2. The prefabricated support and hanger connection structure adopts a floating design for the insertion part.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] This utility model provides an embodiment: Please refer to Figures 1-6 A prefabricated support and hanger connection structure includes an insertion part and a locking part. The insertion part includes a vertical rod 2 adapted to the mounting holes of the prefabricated support and hanger, a limiting plate 22 connected to one end of the vertical rod 2, and a positioning block 10 connected to the other end of the vertical rod 2. Limiting grooves 9 are provided on both sides of the other end of the vertical rod 2. The outer diameter of the limiting plate 22 is larger than the outer diameter of the vertical rod 2, and the outer diameter of the positioning block 10 is not larger than the outer diameter of the vertical rod 2. The size of the insertion part can be set according to requirements and is not limited here. A buffer pad is provided on the top of the limiting plate 22 to reduce the impact force when the limiting plate 22 contacts the prefabricated support and hanger, and to increase the friction between the two, thereby improving the stability of the connection structure. The material of the buffer pad can be set according to requirements and is not limited here.

[0022] The locking part includes a hollow shell 1. The limiting plate 22 and the hollow shell 1 are in a magnetically attracted state. The materials of the limiting plate 22 and the hollow shell 1 can be set according to the requirements and are not limited here. A through hole adapted to the upright 2 is provided in the middle of the bottom of the hollow shell 1. Through the through hole, both the upright 2 and the positioning block 10 can be inserted into the inner cavity of the hollow shell 1.

[0023] A locking sleeve 12 is movably connected to the inner cavity of the hollow shell 1. A first spring 11 is evenly arranged on the top of the locking sleeve 12. The top of the first spring 11 is connected to the top of the inner cavity of the hollow shell 1. The locking sleeve 12 is connected to the hollow shell 1 through the first spring 11. When the locking sleeve 12 is released, under the action of the rebound force of the first spring 11, the locking sleeve 12 can move upward and away from the through hole provided at the bottom of the inner cavity of the hollow shell 1.

[0024] A slot 6 is provided on one side of the hollow shell 1. A handle 7 is movably connected to the inner cavity of the slot 6. One end of the handle 7 extends to the outside of the hollow shell 1, and the other end of the handle 7 is connected to the locking sleeve 12. Anti-slip pads 8 are provided on both sides of the bottom end of the slot 6. With the handle 7, the construction personnel can move the locking sleeve 12 by using the handle 7, which facilitates the reset of the locking sleeve 12. When the end of the locking sleeve 12 away from the first spring 11 is in contact with the inner wall of the hollow shell 1, the handle 7 is located between the two anti-slip pads 8. The friction between the anti-slip pads 8 and the handle 7 can reduce the tension of the first spring 11 on the locking sleeve 12, making it easier for the construction personnel to press the handle 7. The anti-slip pads 8 can be set according to needs and are not limited here.

[0025] The locking sleeve 12 has a hollow structure. A through hole is located in the center of the bottom of the inner cavity of the locking sleeve 12, through which the upright rod 2 can be inserted into the inner cavity of the locking sleeve 12. Limiting blocks 13 are movably connected to both sides of the bottom end of the inner cavity of the locking sleeve 12. A sliding groove 20 is provided at the bottom of the limiting block 13, and a slider 19 is movably connected within the sliding groove 20. The slider 19 is connected to the bottom of the inner cavity of the locking sleeve 12. The limiting block 13 is connected to the slider 19 via a second spring 21. Due to the second spring 21, the position of the limiting block 13 can change under external force. When the limiting block 13 is subjected to outward pulling force, the two limiting blocks 13 move away from each other, and the end of the limiting block 13 closest to the hollow shell 1 can move to the outside of the locking sleeve 12. When the restriction on the limiting block 13 is released, under the action of the rebound force of the second spring 21, the two limiting blocks 13 move closer to each other, and the end of the limiting block 13 closest to the hollow shell 1 can return to its original position.

[0026] Fixed grooves 14 are provided on both sides of the bottom end of the hollow shell 1. The fixed grooves 14 are adapted to the limiting blocks 13. A pull rope 5 is movably connected to the inner cavity of the fixed grooves 14. One end of the pull rope 5 is connected to the limiting block 13, and the other end of the pull rope 5 passes through the hollow shell 1 and extends to the outside of the hollow shell 1. The pull rope 5 and the hollow shell 1 are in a movably connected state. A pull ring 4 is movably sleeved on the outer ring of the hollow shell 1. The other end of the pull rope 5 is fixedly connected to the pull ring 4. When the end of the locking sleeve 12 away from the first spring 11 is in contact with the inner wall of the hollow shell 1, the limiting block 13 and the fixed grooves 14 are at the same height. When the construction personnel move the pull rope 5 outward by pulling the ring 4, the limiting block 13 can move into the fixed groove 14. At this time, the end of the limiting block 13 away from the pull rope 5 is still located in the inner cavity of the locking sleeve 12. At this time, the locking sleeve 12 is limited by the limiting block 13.

[0027] A groove 3 is provided on one side of the hollow shell 1. The pull ring 4 is movably connected to the inner cavity of the groove 3. The groove 3 can restrict the pull ring 4 so that the pull ring 4 can only move in the direction of the hollow shell 1. Furthermore, there is damping between the pull ring 4 and the hollow shell 1. When the restriction on the pull ring 4 is released, the position of the pull ring 4 can remain unchanged.

[0028] A positioning sleeve 18 is movably connected to the top of the inner cavity of the locking sleeve 12. A guide groove 17 is provided at the top of the inner cavity of the locking sleeve 12. A guide rod 16 is movably connected in the guide groove 17. The guide rod 16 is connected to the outer wall of the positioning sleeve 18. The positioning sleeve 18 is limited by the guide groove 17 and the guide rod 16, so that the positioning sleeve 18 can only move up and down in the inner cavity of the hollow shell 1. This avoids abnormal wear of the positioning block 10 caused by the rotation of the positioning sleeve 18 when the insertion part and the locking part are locked.

[0029] The limiting block 13 is L-shaped. The outer wall of the vertical end of the limiting block 13 is adapted to the inner wall of the locking sleeve 12, and the inner wall of the vertical end of the limiting block 13 is adapted to the outer wall of the positioning sleeve 18. When the end of the limiting block 13 away from the positioning sleeve 18 is tightly fitted with the fixing groove 14, the distance between the vertical ends of the two limiting blocks 13 is adapted to the positioning sleeve 18. Under the action of gravity, the positioning sleeve 18 can fall between the two limiting blocks 13, and the positioning sleeve 18 is used to restrict the limiting block 13. At this time, a positioning groove 15 that matches the positioning block 10 is formed between the two limiting blocks 13. When the positioning block 10 and the positioning groove 15 are misaligned, the limiting block 13 restricts the positioning block 10, preventing the insertion part from being inserted further. When the positioning block 10 is aligned with the positioning groove 15, the positioning block 10 can be inserted into the positioning groove 15. At this time, the limiting block 13 and the limiting groove 9 are located on the same side of the upright 2. The continued insertion of the positioning block 10 can contact the positioning sleeve 18 and push the positioning sleeve 18 to move. When the positioning sleeve 18 separates from the limiting block 13, and the limiting block 13 is aligned with the limiting groove 9, the limiting block 13 can be inserted into the limiting groove 9 under the action of the rebound force of the second spring 21. When the locking sleeve 12 moves, the insertion part can be moved through the limiting block 13.

[0030] The materials, elastic coefficients, and compression strokes of both the first spring 11 and the second spring 21 can be set according to requirements and are not limited here. When the positioning block 10 contacts the positioning sleeve 18, the positioning block 10 and the positioning sleeve 18 are in a magnetically attracted state, preventing the insertion part from falling to the ground when the connection structure is disassembled, and facilitating the recovery of the insertion part. The materials of both the positioning block 10 and the positioning sleeve 18 can be set according to requirements and are not limited here.

[0031] Before use, the insertion part and the locking part of the prefabricated support and hanger connection structure are separated, and the positioning sleeve 18 and the two limiting blocks 13 are mutually limited. Under the action of the rebound force of the second spring 21, the two limiting blocks 13 can clamp the positioning sleeve 18, so that the position of the positioning sleeve 18 in the locking sleeve 12 remains unchanged. Under the action of the positioning sleeve 18, the ends of the two limiting blocks 13 that are far apart from each other are located in the fixing groove 14. The limiting blocks 13 limit the locking sleeve 12. That is, before use, the position of the lock cylinder composed of the positioning sleeve 18, the limiting blocks 13 and the locking sleeve 12 in the locking part remains unchanged, and the limiting blocks 13 can position the insertion part.

[0032] When using this prefabricated support and hanger connection structure, the construction personnel align the mounting holes of the two components to be connected to form a hole for the insertion part. The locking part and the insertion part are placed on either side of the hole, preferably with the insertion part below the hole and the locking part above. The construction personnel insert the insertion part into the locking part through the hole, adjusting the position of the insertion part during insertion so that the positioning block 10 can be inserted into the positioning groove 15. When the positioning block 10 contacts the bottom of the positioning sleeve 18, the continued insertion of the insertion part causes the positioning block 10 to press against the positioning sleeve 18. Under the pressure of the pressing force... When inserted, the positioning sleeve 18 can be pushed upward. When the positioning sleeve 18 separates from the limiting block 13, the limiting block 13 and the limiting groove 9 are aligned. Under the action of the first spring 11, the locking sleeve 12 can pull the insertion part upward through the limiting block 13. At this time, the construction personnel can release the restriction on the insertion part. Under the action of the first spring 11, the limiting plate 22 gradually approaches the bottom of the hole until the limiting plate 22 is tightly fitted with the bottom of the hole. At this time, the two parts to be connected are clamped in the limiting plate 22 and the hollow shell 1, realizing the rapid installation of the two parts to be connected in the prefabricated support.
