Description

Technical Field

[0001] This utility model relates to the field of embedded part positioning technology, and more specifically, to a magnetic positioning device for embedded parts in walls. Background Technology

[0002] Embedded component construction is a crucial hidden engineering technique in building engineering. Its core involves pre-installing metal components with anchoring bars within the structure before concrete pouring. This provides safe and reliable connection points for subsequent curtain wall installation, equipment fixing, pipe connections, and load transfer between the main structure and other components. As modern architecture develops towards high-rise buildings, large spans, and more complex shapes, extremely high demands are placed on the positioning accuracy, structural strength, and durability of embedded components. The quality of their construction directly affects the safety and service life of the overall project, serving as a fundamental link to ensure the smooth progress of subsequent installation work and structural stability.

[0003] In the prior art, for example, patent publication number CN119616232A discloses a pre-embedded part positioning and adsorption device and a pre-embedded part construction method. This device uses a powerful magnet to position the pre-embedded part in the wall, and a shielding material to interrupt the magnetism so that the magnet can be removed. However, the shielding material needs to be thin, lightweight, and rollable, and materials that meet these requirements are expensive, resulting in high implementation costs. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a magnetic positioning device for wall embedded parts. By moving the magnet, the magnet only needs to provide localized magnetism, reducing the size of the magnet. The handle increases the torque when unloading the magnet, reducing the difficulty of removing the magnet and lowering costs.

[0005] This utility model is achieved through the following technical solution: a magnetic positioning device for wall embedded parts, including a template, a base slidably connected to the template, a driving component for driving the base to move along the X and Y axes on the template, a lead screw rotatably connected to the base along the Z axis, a lead screw nut slidably connected to the lead screw, a magnet fixedly connected to the lead screw nut, and a crank handle fixedly connected to the end of the lead screw away from the base, the length of the crank handle being greater than the diameter of the lead screw.

[0006] Furthermore, the crank includes a handle body, one end of which is fixedly connected to a lead screw, and the other end of which is rotatably connected to a handle.

[0007] Furthermore, the handle is fitted with a rubber sleeve.

[0008] Furthermore, a ratchet is coaxially fixedly connected to the bottom of the lead screw, and a check pawl is slidably connected to the base.

[0009] Furthermore, the anti-return pawl includes a base block, a pawl body rotatably connected to the base block, an elastic element for resetting the pawl body fixedly connected to the base block, a locking rod slidably connected to the base block, and several locking grooves provided on the base.

[0010] Furthermore, auxiliary slide rods are provided on both sides of the lead screw, and the auxiliary slide rods are fixedly connected to the base. Wing plates are fixedly connected to both sides of the lead screw nut, and the wing plates are slidably connected to the auxiliary slide rods.

[0011] Furthermore, the template is fixedly connected to all four sides with clips.

[0012] The technical solution of this utility model has at least the following beneficial effects: In use, the template can be used in conjunction with other mold structures for shaping. The template is responsible for shaping the cement or concrete at the embedded parts of the wall. During use, first use the crank to turn the lead screw clockwise. The lead screw nut will slide to the top of the lead screw. The magnet is far from the wall to be shaped, resulting in a small interaction force, making it convenient for the user to adjust the position of the template and base, and reducing the impact of magnetic resistance during adjustment.

[0013] After determining the template position, adjust the base position using the drive mechanism to change the X and Y axis positions of the base on the template, aligning the magnet with the embedded part. Once aligned, rotate the screw using the crank handle to reverse the screw, causing the screw nut to slide to the bottom of the screw. At this point, the magnetic field of the magnet will penetrate the template and attract the embedded part on the other side of the template, causing the embedded part to be pressed tightly against the template by the magnetic force. When the wall to be formed is poured later, the embedded part is less likely to shift under the constraint of the magnetic force, thus reducing the positional deviation of the embedded part.

[0014] After the grout has solidified and the pouring is complete, the embedded parts will be constrained by the solidified wall. At the demolding time, the screw is first rotated using a crank handle to move the magnet away from the formwork. Rotating the crank handle at this point requires overcoming the magnetic attraction of the magnet. Due to the relatively long length of the crank handle, the torque generated when driving it is greater, making it easier to overcome the magnetic attraction and move the magnet away from the formwork. Once the magnet is away from the formwork, the force exerted by the magnet on the embedded parts decreases, allowing the formwork to be removed. Attached Figure Description

[0017] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] The following detailed description illustrates the specific implementation method: Example 1: As attached Figures 1-5As shown: A magnetic positioning device for wall embedded parts includes a template 1, which can be made of wood to facilitate magnetic penetration. A base 2 is slidably connected to the template 1. The template 1 is provided with a driving component 3 that drives the base 2 to move along the X-axis and Y-axis. The driving component 3 is a screw assembly, which includes a first screw along the X-axis of the template 1 and a second screw slidably connected to the first screw along the Y-axis of the template 1. The second screw drives the base 2. Both the first screw and the second screw are self-locking. A lead screw 4 along the Z-axis is rotatably connected to the base 2. A lead screw nut 5 is slidably connected to the lead screw 4. A magnet 6 is bolted to the lead screw nut 5. The magnet 6 extends towards the template 1. When the lead screw nut 5 is at its lowest point on the lead screw 4, the magnet 6 abuts against the template 1. A rocker arm 7 is bolted to the end of the lead screw 4 away from the base 2. The length of the rocker arm 7 is greater than the diameter of the lead screw 4. The rocker arm 7 includes a handle body 701. One end of the handle body 701 is fixedly connected to the lead screw 4. The other end of the handle body 701 is rotatably connected to a handle 702. A rubber sleeve 703 is fitted over the handle 702.

[0021] Auxiliary slide rods 10 are provided on both sides of the lead screw 4. The auxiliary slide rods 10 are welded and fixed to the base 2. The lead screw nut 5 has wing plates 11 integrally formed on both sides. The wing plates 11 are slidably connected to the auxiliary slide rods 10. The template 1 has buckles 12 bolted to all four sides.

[0022] Template 1 can be used with other mold structures for shaping. Template 1 is responsible for the cement or concrete molding at the wall embedded parts. Clip 12 can facilitate the connection of template 1 with other molds to form a continuous plane.

[0023] In use, first use the crank handle 7 to rotate the lead screw 4 so that the lead screw 4 rotates clockwise. The lead screw nut 5 will slide to the top of the lead screw 4. The magnet 6 is far away from the wall to be formed, and the interaction force is small, which makes it convenient for the user to adjust the position of the template 1 and the base 2 and reduces the impact of magnetic resistance during the adjustment process.

[0024] The auxiliary slide bar 10 can assist the sliding process of the lead screw nut 5. When the lead screw nut 5 slides on the lead screw 4, it will also slide synchronously on the auxiliary slide bar 10, so that the sliding process of the lead screw nut 5 is constrained in many ways and is less likely to undergo angular changes such as rotation.

[0025] After determining the position of template 1, the position of base 2 is adjusted by drive component 3, changing the X and Y axis positions of base 2 on template 1, so that magnet 6 is aligned with the embedded part. After alignment, screw 4 can be rotated by crank handle 7 to reverse screw 4. Screw nut 5 will slide to the bottom of screw 4. At this time, the magnetic field of magnet 6 will penetrate template 1 and attract the embedded part on the other side of template 1, so that the embedded part is pressed tightly against template 1 by magnetic force. When the wall to be formed is poured later, the embedded part is less likely to be displaced under the constraint of magnetic force, so as to reduce the positional deviation of the embedded part.

[0026] After the grout has solidified, the embedded parts will be constrained by the solidified wall. At the demolding point, the crank handle 7 is used to rotate the screw 4 to move the magnet 6 away from the template 1. Rotating the crank handle 7 requires overcoming the magnetic attraction of the magnet 6. Due to the relatively long length of the crank handle 7, the torque generated when driving it is greater, making it easier to overcome the magnetic attraction and move the magnet 6 away from the template 1. The handle 702 is rotatably connected to the handle body 701, allowing the user to adjust their hand position during rotation, improving the user experience. The rubber sleeve 703 increases the friction between the handle 702 and the user's hand, reducing the probability of the handle 702 falling off.

[0027] When the magnet 6 moves away from the template 1, the force exerted by the magnet 6 on the embedded part decreases, and the template 1 can then be removed.

[0028] Example 2: The difference from the above embodiment is that a ratchet 8 is coaxially welded and fixed to the bottom of the lead screw 4, and a check pawl 9 is slidably connected to the base 2. The check pawl 9 includes a base block 901, a pawl body 902 is unidirectionally hinged to the base block 901, and an elastic element for resetting the pawl body 902 is fixedly connected to the base block 901. The elastic element is a torsion spring (not shown in the figure). A locking rod 903 is slidably connected to the base block 901, and the base 2 is provided with several locking grooves 904.

[0029] At the demolding time, it is necessary to rotate the rocker handle 7 to move the magnet 6 away from the template 1. However, in the initial stage of rocking, the magnet 6 is close to the embedded part and the resistance to be overcome is strong. If the user releases the handle while rotating it, the magnet 6 can easily attract the embedded part and reset the magnet 6.

[0030] The user can slide the anti-return pawl 9 while turning the crank 7, causing the anti-return pawl 9 to interact with the ratchet 8. Once the anti-return pawl 9 has slid into position, the sliding locking bar 903 moves into the locking groove 904, locking the anti-return pawl 9 in place. The ratchet 8 is unidirectional; when the user turns the crank 7 to move the magnet 6 away from the template 1, the ratchet 8 will rotate accordingly. When the user releases the crank during this process, due to its unidirectional rotation, the ratchet 8 reverses direction and is caught by the anti-return pawl 9, thus locking the magnet 6. This prevents the magnet 6 from driving the screw nut 5 to slide under magnetic attraction, making it easier for the user to remove the template 1. After the template 1 is removed, the anti-return pawl 9 maintains its position. When the template 1 is reused, the locking bar 903 of the anti-return pawl 9 can slide out of the locking groove 904 before the driving magnet 6 approaches the template 1, causing the anti-return pawl 9 to disengage from the ratchet 8, restoring the screw 4's bidirectional rotation capability.

[0031] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
