[0052] The present application provides a pre-embedded connection mechanism for realizing the connection and fixation between a modular building or other modular components and a basic structure, so that the modular building or other modular components can be quickly installed on the basic structure. The basic structure described herein can be the ground, a wall or other structure, and the pre-embedded connection mechanism is installed on the basic structure in a form perpendicular to the basic structure, and the pre-embedded connection mechanism is at least partially embedded in the basic structure.
[0053] Taking the embedded connection mechanism used to achieve the connection and fixation of modular buildings and infrastructure as an example, the specific embodiments of the embedded connection mechanism of the present application are described in detail below with reference to the accompanying drawings.
[0054] Figure 1 is a first structural schematic diagram of the embedded connection mechanism in this embodiment, Figure 2 is a schematic diagram of the first three-dimensional structure of the embedded connection mechanism in this embodiment, Figure 3 for Figure 2 Schematic diagram of the exploded structure of the embedded connection mechanism.
[0055] For the convenience of description, it is now stipulated that the direction in which the embedded connection mechanism faces the basic structure 100 is the back side, and the opposite direction is the front side.
[0056] refer to Figure 1 to Figure 3 The embedded connection mechanism includes an embedded part 1, a connecting part 2 and a limiting part 3.
[0057] The embedded component 1 is embedded in the foundation structure 100 , and includes an embedded plate 11 and a plurality of embedded rods 12 .
[0058] In this embodiment, the embedded plate 11 is in the shape of a plate, and its two opposite sides are respectively the front side and the back side. When the embedded part 1 is embedded in the foundation structure, the front side of the embedded plate 11 is flush with the surface of the foundation structure 100 or protrudes from the surface of the foundation structure 100. Specifically, the embedded plate 11 is in the shape of a square plate. In other embodiments, the embedded plate 11 may also be in the shape of a circular plate or a plate of other shapes.
[0059] The embedded plate 11 is provided with a connection hole 111. In this embodiment, the inner diameter of the connection hole 111 includes a long aperture and a short aperture, the long aperture and the short aperture pass through the same point on the axis of the connection hole 111, and the long aperture is larger than the short aperture. That is, in this embodiment, the connection hole 111 is a waist-shaped hole. Specifically, the connection hole 111 is a square hole. In other embodiments, the connection hole 111 may also be an elliptical hole or other shapes, which are not limited here.
[0060] A plurality of embedded rods 12 are circumferentially arranged on one side of the embedded plate 11, and their extending direction is parallel to the axial direction of the connecting hole 111. Specifically, a plurality of embedded rods 12 are circumferentially arranged on the back side of the embedded plate 11. When the embedded part 1 is embedded in the foundation structure, the plurality of embedded rods 12 are embedded in the foundation structure 100.
[0061] In this embodiment, the number of the embedded rods 12 is four.
[0062] The connector 2 is movably connected to the embedded part 1, and is used to realize the connection between the modular building and the embedded part 1, so as to realize the connection between the modular building and the basic structure 100. In this embodiment, the connector 2 is connected to the embedded part 1 through the connecting hole 111, wherein a stop block 21 is provided at the end of the connector 2, and the outer contour of the stop block 21 includes a first side 211 and a second side 212, the size of the first side 211 is smaller than the long aperture, and the size of the second side 212 is smaller than the short aperture, so that the stop block 21 passes through the connecting hole 111 when the first side 211 extends along the extension direction of the long aperture, so that the connector 2 is convenient to be inserted into the embedded part 1, or the connector 2 is convenient to be separated from the embedded part 1. The size of the first side 211 is larger than the short aperture, so that when the second side 212 extends along the extension direction of the long aperture, the stop block 21 is restricted from passing through the connecting hole 111, so that the connector 2 is connected and fixed to the embedded part 1. Furthermore, since the connection hole 111 is a waist-shaped hole, the connection member 2 can slide in the connection hole 111 relative to the embedded member 1 to change the position of the connection member 2 in the connection hole 111, thereby achieving position adjustment of the connection member 2 to meet the assembly requirements of the connection member 2 and the structural components of the modular building.
[0063] Figure 4 Schematic diagram of the structure of the connecting member 2 in this embodiment.
[0064] refer to Figure 4 In this embodiment, the connecting member 2 includes a rod body 22 and a limit block 21 provided at one end of the rod body 22 .
[0065] The cross-section of the rod body 22 is circular, and the outer diameter of the rod body 22 is less than or equal to the short hole diameter of the connecting hole 111. When the connecting member 2 is connected to the embedded plate 11 of the embedded member 1, the rod body 22 is inserted into the connecting hole 111, and the rod body 22 protrudes out of the front side of the embedded plate 11, and the rod body 22 can rotate and move in the connecting hole 111.
[0066] At least part of the outer periphery of the rod body 22 is provided with external threads. Specifically, the external threads and the stopper 21 are arranged at opposite ends of the rod body 22. When the connector 2 is connected to the embedded plate 11, the part of the rod body 22 protruding from the front of the embedded part 1 has external threads, which is used to connect and fix with the modular building.
[0067] The limit block 21 is sleeved on the rod body 22, and the opposite ends of the limit block 21 protrude outward from the rod body 22 along the radial direction of the rod body 22. When the connector 2 is connected to the embedded plate 11, the limit block 21 and the embedded rod 12 are in the same direction relative to the embedded plate 11, that is, the limit block 21 is located on the back of the embedded plate 11.
[0068] The outer contour of the stopper 21 includes a first side 211 and a second side 212, and the size of the first side 211 is larger than the size of the second side 212. The second side 212 is smaller than or equal to the outer diameter of the rod body 22, the first side 211 is larger than the outer diameter of the rod body 22, and both ends of the first side 211 in the extension direction protrude outward from the rod body 22 along the radial direction of the rod body 22. The outward mentioned here refers to the direction away from the axial direction of the rod body 22.
[0069] In this embodiment, the limiting block 21 is in a square shape.
[0070] In other embodiments, the outer contour of the stopper 21 includes two first sides 211 and two second sides 212, the two first sides 211 are straight and parallel, the two second sides 212 are arc-shaped, and the two second sides 212 are mirror-symmetrical. In this case, the minimum distance between the two first sides 211 is less than or equal to the outer diameter of the rod body 22, the first side 211 is larger than the outer diameter of the rod body 22, and the two ends of the first side 211 in the extension direction protrude outward from the rod body 22 along the radial direction of the rod body 22. The outward mentioned here refers to the direction away from the axial direction of the rod body 22.
[0071] In other embodiments, the cross-section of the limiting block 21 may also be elliptical or in other shapes. The specific configuration depends on the actual needs and is not limited here.
[0072] In this embodiment, the size of the first side 211 is smaller than the long aperture, and the size of the second side 212 is smaller than the short aperture, so that the stop block 21 passes through the connection hole 111 when the first side 211 extends in the extension direction of the long aperture, and the size of the first side 211 is larger than the short aperture, so that the stop block 21 is restricted from passing through the connection hole 111 when the second side 212 extends in the extension direction of the long aperture. The above arrangement enables the stop block 21 of the connector 2 to pass through the connection hole 111, and then by rotating the rod body 22 at a certain angle, the second side 212 of the stop block 21 extends in the extension direction of the long aperture, so that the stop block 21 cannot pass through the connection hole 111 of the embedded plate 11 to detach from the embedded member 1, thereby achieving the connection between the connector 2 and the embedded plate 11. Alternatively, by rotating the rod body 22 at a certain angle, the first side 211 of the limit block 21 is extended along the extension direction of the long aperture, so that the limit block 21 can pass through the connecting hole 111 of the embedded plate 11 to disengage from the embedded part 1, thereby releasing the connection between the connecting part 2 and the embedded plate 11, so as to realize a detachable connection between the connecting part 2 and the embedded plate 11, thereby facilitating the replacement of the connecting part 2.
[0073] In this embodiment, the connector 2 further includes a limiting portion 23. The limiting portion 23 is disposed at one end of the rod body 22, and the limiting portion 23 protrudes outward from the rod body 22 along the circumferential direction or radial direction of the rod body 22, so that the limiting portion 23 facing the side of the rod body 22 can abut against the limiting block 21 to prevent the limiting block 21 from falling off the rod body 22.
[0074] In this embodiment, the limiting portion 23 and the rod body 22 are integrally formed connecting bolts.
[0075] Figure 5 It is a schematic diagram of the structure of the connecting member 2 in other embodiments.
[0076] refer to Figure 5 In other embodiments, the connecting member 2 may only include the rod body 22 and the limiting block 21. Specifically, the connecting member 2 is an integrally formed T-bolt.
[0077] Continue to refer Figure 1 to Figure 3 The limiting member 3 is clamped in the connecting hole 111 and connected to the embedded member 1, and the limiting member 3 is clamped with the limiting block 21 to realize the connection with the connecting member 2, so as to limit the rotation of the limiting block 21, so that in the process of connecting the structural components of the modular building, the limiting block 21 cannot rotate to the first side 211 extending along the extension direction of the long aperture and detaching from the embedded member 1, thereby improving the stability of the connection between the connecting member 2 and the embedded member 1.
[0078] The stopper 3 is provided with a stopper groove 31 with an opening, and the stopper block 21 is clamped in the stopper groove 31. The outer wall of the stopper 3 along the extension direction of the short aperture abuts against the inner peripheral wall of the connection hole 111 and is clamped in the connection hole 111. Specifically, when the stopper 3 is clamped in the connection hole 111, the direction of its opening is consistent with the direction of the embedded rod 12 relative to the embedded plate 11, that is, the stopper 3 is clamped in the connection hole 111 with the opening facing the back of the embedded plate 11.
[0079] In other embodiments, the outer wall of the limit member 3 along the extension direction of the short aperture abuts against the inner circumferential wall of the connecting hole 111, and the outer wall of the limit member 3 along the extension direction of the long aperture abuts against the inner circumferential wall of the connecting hole 111, thereby limiting the movement of the limit member 3 in the connecting hole 111, and further limiting the movement of the limit block 21 relative to the embedded plate 11, so as to achieve the positioning of the connecting member 2.
[0080] The limiting member 3 includes two side plates 32 arranged in parallel and spaced apart and an end plate 33 connected to one end of the two side plates 32, and the two side plates 32 and the end plate 33 enclose a limiting groove 31. The two side plates 32 are used to abut against the two first edges 211 respectively, and the dimension of the end plate 33 along the extension direction of the short aperture is adapted to the short aperture, so as to abut against the inner peripheral wall of the connecting hole 111.
[0081] The end plate 33 is provided with a through hole 331 for the rod body 22 of the connecting member 2 to pass through, so that the limiting member 3 can be sleeved on the rod body 22. That is, the limiting member 3 can be sleeved on the rod body 22 with its opening facing the back of the embedded plate 11, and can move relative to the rod body 22 along the axial direction of the rod body 22, and be clamped in the connecting hole 111, and the accommodating groove of the limiting member 3 accommodates part of the limiting block 21 and is clamped with the limiting block 21.
[0082] Further, the embedded connection mechanism includes at least one first adjustment member 4. When the limit block 21 extends along the extension direction of the long aperture on the second side 212, the first adjustment member 4 is arranged between the first side 211 and the inner side wall of the connection hole 111, and the opposite ends of the first adjustment member 4 abut against the first side 211 and the inner side wall of the connection hole 111, respectively, to locate the position of the limit block 21 in the connection hole 111 along the extension direction of the long aperture, and to limit the limit block 21 from sliding relative to the embedded member 1.
[0083] In this embodiment, the embedded connection mechanism includes a plurality of first adjustment members 4 with different thicknesses. One or more first adjustment members 4 with different thicknesses can be selected as needed to abut between the first edge 211 and the inner wall of the connection hole 111 .
[0084] In other embodiments, the embedded connection mechanism may include a plurality of first adjustment members 4 with the same thickness, and one or more first adjustment members 4 may be selected as needed to abut between the first edge 211 and the inner wall of the connection hole 111 .
[0085] In this embodiment, the first adjusting member 4 is a gasket.
[0086] In other embodiments, when the outer wall of the limit member 3 along the extension direction of the short aperture abuts against the inner circumferential wall of the connecting hole 111 and the outer wall of the limit member 3 along the extension direction of the long aperture abuts against the inner circumferential wall of the connecting hole 111, the embedded connecting mechanism may not include the first adjusting member 4, and the specific setting depends on the needs.
[0087] The embedded connection mechanism includes a first embedded box 5, which is correspondingly arranged at the connection hole 111 of the embedded component 1. Specifically, the first embedded box 5 is arranged on the back of the embedded plate 11, and is correspondingly located at the connection hole 111.
[0088] The first embedded box 5 is formed with a receiving space with an opening at one end, and the receiving space is communicated with the connecting hole 111 through the opening, and the receiving space is used to receive the limit block 21, part of the limit member 3 and the first adjusting member 4, and the first embedded box 5 also has the function of supporting and preventing the limit block 21, the limit member 3 and the first adjusting member 4 from falling. The opening direction of the first embedded box 5 is opposite to the direction of the embedded rod 12 relative to the embedded plate 11, that is, the opening of the first embedded box 5 faces the front of the embedded plate 11.

[0090] refer to Figure 6 to Figure 8 The embedded connection mechanism also includes at least one positioning member 6, which is used to realize the positioning of the structural components of the modular building. The embedded member 1 is provided with a positioning hole 112, and the positioning member 6 is inserted into the positioning hole 112, and the inner peripheral wall of the positioning hole 112 abuts against the outer periphery of the positioning member 6. Specifically, the positioning hole 112 is provided on the embedded plate 11, and there is a gap between it and the connection hole 111. The shape and size of the positioning hole 112 can be adapted to the shape and size of the outer contour of the cross section of the positioning member 6 along the direction parallel to the embedded plate 11, so that the inner peripheral wall of the positioning hole 112 can abut against the outer periphery of the positioning member 6 to prevent the positioning member 6 from moving relative to the embedded plate 11.
[0091] In this embodiment, the positioning hole 112 is a non-circular hole, and the cross section of the positioning member 6 is non-circular. After the inner wall of the positioning hole 112 abuts against the outer periphery of the positioning member 6, the positioning member 6 can be prevented from rotating relative to the embedded plate 11.
[0092] In other embodiments, the positioning hole 112 may be a square hole, an elliptical hole, etc. Adaptively, the outer contour of the cross section of the positioning member 6 along a direction parallel to the embedded plate 11 is square, elliptical, etc.
[0093] In this embodiment, the inner diameter of the positioning hole 112 includes a first aperture and a second aperture, and the first aperture is greater than or equal to the second aperture. The outer contour of the cross section of the positioning member 6 along the direction parallel to the embedded plate 11 includes a long side and a short side. Specifically, the outer contour of the cross section of the positioning member 6 along the direction parallel to the embedded plate 11 includes two long sides and two short sides, the two long sides are straight and parallel, and the two short sides are arc-shaped and mirror-symmetrical. Among them, the size of the long side is equal to the first aperture, and the minimum distance between the two long sides is equal to the second aperture, so that the outer periphery of the positioning member 6 can directly abut against the inner peripheral wall of the positioning hole 112 to prevent the positioning member 6 from rotating and moving relative to the embedded plate 11.
[0094] In other embodiments, in the outer contour of the cross section of the positioning member 6 along the direction parallel to the embedded plate 11, the long side is smaller than the first aperture, and the minimum distance between the two long sides is equal to the second aperture. Alternatively, the long side is equal to the first aperture, and the minimum distance between the two long sides is smaller than the second aperture. Alternatively, the long side is smaller than the first aperture, and the minimum distance between the two long sides is smaller than the second aperture. At this time, the positioning member 6 can move in the positioning hole 112 to adjust the position of the positioning member 6 in the positioning hole 112 to meet the assembly requirements of the positioning member 6 and the structural components of the modular building.

Specifically, the positioning member 6 includes a main body 61 and a cone 62. When the positioning member 6 is installed on the embedded plate 11, the main body 61 is inserted into the positioning hole 112, and the outer periphery of the main body 61 abuts against the inner peripheral wall of the positioning hole 112. The cone 62 is located on the front of the embedded plate 11, and its cross section is an isosceles triangle.
[0098] Fig.10 Schematic diagram of the structure of the positioning member 6 in other embodiments.
[0099] refer to Fig.10 In other embodiments, the positioning member 6 can be composed of two or more cylinders or square tubes combined into a combination of cross-sectional shapes with different sizes in the length direction and the width direction.
[0100] refer to Figure 6 to Figure 8Further, the embedded part 1 is provided with a second embedded box 7, and the second embedded box 7 is located at the positioning hole 112. Specifically, the second embedded box 7 is provided on the back of the embedded plate 11, and is located at the positioning hole 112.
[0101] The second embedded box 7 is formed with an inner space with an opening at one end, and the inner space is communicated with the positioning hole 112 through the opening, and is used to accommodate part of the positioning member 6, and the second embedded box 7 also has the function of supporting and preventing the positioning member 6 from falling. The opening direction of the second embedded box 7 is opposite to the direction of the embedded rod 12 relative to the embedded plate 11, that is, the opening of the second embedded box 7 faces the front of the embedded plate 11.
[0102] It can be seen from the above technical solution that the utility model has at least the following advantages and positive effects:
[0103] First, the embedded part is provided with a connecting hole, the inner diameter of the connecting hole includes a long aperture and a short aperture, the long aperture and the short aperture pass through the same point on the axis of the connecting hole, and the long aperture is larger than the short aperture. The connecting part is movably connected to the embedded part. A stop block is provided at the end of the connecting part, and the outer contour of the stop block includes a first side and a second side. The size of the first side is smaller than the long aperture, and the size of the second side is smaller than the short aperture, so that the stop block passes through the connecting hole when the first side extends in the extension direction of the long aperture, and the size of the first side is larger than the short aperture, so that the stop block is restricted from passing through the connecting hole when the second side extends in the extension direction of the long aperture. The above arrangement enables the stop block of the connecting part to pass through the connecting hole, and then by rotating the rod body at a certain angle, the second side of the stop block extends in the extension direction of the long aperture, so that the stop block cannot pass through the connecting hole of the embedded plate to detach from the embedded part, thereby realizing the connection between the connecting part and the embedded plate. Alternatively, by rotating the rod body at a certain angle, the first edge of the limit block extends in the extension direction of the long aperture, so that the limit block can pass through the connecting hole of the embedded plate to disengage from the embedded part, thereby releasing the connection between the connecting part and the embedded plate, making it easier to replace the connecting part.
[0104] In addition, the limiting piece is clamped in the connecting hole and connected to the embedded part, and the limiting piece is clamped with the limiting block to realize the connection with the connecting piece, so as to limit the rotation of the limiting block, so that in the process of connecting the structural components of the modular building, the limiting block cannot be rotated to extend in the extension direction of the long aperture of the first edge and detach from the embedded part, thereby improving the stability of the connection between the connecting piece and the embedded part.
[0105] Further, the embedded connection mechanism includes at least one first adjustment member. When the limiting block extends along the extension direction of the long aperture on the second edge, the first adjustment member is arranged between the first edge and the inner side wall of the connection hole, and the opposite ends of the first adjustment member abut against the first edge and the inner side wall of the connection hole respectively, so as to locate the position of the limiting block in the connection hole along the extension direction of the long aperture, and limit the sliding of the limiting block relative to the embedded member.
[0106] Although the utility model has been described with reference to several typical embodiments, it should be understood that the terms used are illustrative and exemplary, rather than restrictive. Since the utility model can be implemented in a variety of forms without departing from the spirit or essence of the utility model, it should be understood that the above-mentioned embodiments are not limited to any of the aforementioned details, but should be widely interpreted within the spirit and scope defined by the attached claims, so all changes and modifications falling within the scope of the claims or their equivalents should be covered by the attached claims.
