DETAILED DESCRIPTION

[0019] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0020] In the present disclosure, unless otherwise stated, the directional words such as "up", "down", "left", "right", etc. used to indicate directions or positional relationships are only for the convenience of describing the present disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, and a specific orientation structure and operation. Therefore, it cannot be understood as a limitation on the present disclosure. The terms "inside and outside" refer to the inside and outside of the corresponding structural contour.

[0021] In addition, it should be noted that the terms used, such as "first", "second", etc., are used to distinguish one element from another element, and do not have order or importance. In addition, in the description with reference to the drawings, the same number in different drawings represents the same element.

[0022] In the description of the present disclosure, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "connect", "connected", and "installed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.

[0023] refer to Figures 1 to 3 As shown, the present disclosure provides a wall connecting device, including an embedded part 10, a connecting frame 20 and a limiting assembly 30. The embedded part 10 is partially embedded in the wall, and the embedded part 10 has a connecting wall 11 exposed outside the wall, the connecting frame 20 is connected to the connecting wall 11, and the side of the connecting frame 20 facing away from the embedded part 10 has an installation portion 200 for accommodating a steel frame 100; the limiting assembly 30 is respectively connected to the embedded part 10 and the connecting frame 20, and is used to limit the steel frame 100 set in the installation portion 200.

[0024] Through the above technical scheme, on the one hand, the setting of the limit assembly 30 can limit the steel frame 100 installed in the installation part 200, thereby improving the stability of the cooperation between the steel frame 100 and the connecting frame 20 and the embedded parts 10, and avoiding or reducing the situation where the steel frame 100 is detached from or loosened from the connecting frame 20. On the other hand, the limit assembly 30 is connected to the embedded parts 10 and the connecting frame 20 respectively. That is to say, while the limit assembly 30 plays a limiting role on the steel frame 100, it can also play a role in improving the connection strength between the connecting frame 20 and the embedded parts 10, thereby avoiding the problem of loosening or falling off of the embedded parts 10 and the connecting structure or loosening or falling off of the steel frame 100 and the connecting structure, thereby improving the service life of the wall connection device.

[0025] It should be noted that the present disclosure does not limit the connection method between the above-mentioned limit assembly 30 and the embedded part 10, as long as the relative fixation between the two can be achieved. For example, the limit assembly 30 can be connected to the connecting wall 11 of the embedded part 10 by welding, fasteners, etc.

[0026] Alternatively, if Figures 1 to 3 As shown, the limiting assembly 30 may include a driving structure 31 and a transmission rod 32, the transmission rod 32 is rotatably connected to the connecting frame 20, and the driving structure 31 is used to drive the transmission rod 32 to rotate around the connecting frame 20 to limit the steel frame 100. Specifically, the transmission rod 32 can be driven by the driving structure 31, so that the transmission rod 32 can rotate relative to the connecting frame 20, and then the transmission rod 32 can stop and limit the steel frame 100 set in the installation part 200, so as to prevent the steel frame 100 from moving in the installation part 200 or escaping from the installation part 200.

[0027] The transmission rod 32 can limit the position of the steel frame 100 disposed in the mounting portion 200 directly, or can limit the position of the steel frame 100 disposed in the mounting portion 200 indirectly. For example, in the embodiment in which the transmission rod 32 provided in the present disclosure limits the position of the steel frame 100 indirectly, optionally, Figures 1 to 3 As shown, the limiting assembly 30 may further include a limiting rod 33, which is rotatably connected to the connecting frame 20 and at least partially located in the mounting portion 200. The limiting rod 33 is in transmission connection with the transmission rod 32, and is used to abut against the steel frame 100 when the driving structure 31 drives the transmission rod 32 to rotate. In this way, in the process of limiting the steel frame 100, the transmission rod 32 can be driven to rotate by the driving structure 31 first, and since the limiting rod 33 is in transmission connection with the transmission rod 32, the transmission rod 32 can drive the limiting rod 33 to move during the rotation process, so that the end of the limiting rod 33 close to the steel frame 100 abuts against the steel frame 100, thereby limiting the steel frame 100.

[0028] The present disclosure does not limit the connection method between the limiting rod 33 and the connecting frame 20. For example, Figure 1 , Figure 3 As shown, the limiting assembly 30 may further include a first hinge shaft 34, an opening 21 is formed on the connecting frame 20, the first hinge shaft 34 is arranged in the opening 21 along the radial direction of the opening 21, the limiting rod 33 includes a first section and a second section connected to each other, a first hinge hole is formed at the connection between the first section and the second section, the first hinge shaft 34 is passed through the first hinge hole, the first section is at least partially located in the mounting portion 200, and the second section is at least partially located outside the mounting portion 200. In this way, the limit rod 33 can rotate around the first hinge axis 34 under the action of the transmission rod 32, and since the first end of the limit rod 33 is at least partially located in the mounting portion 200, and the second section is at least partially located outside the mounting portion 200, the transmission rod 32 can be connected to the second section located outside the mounting portion 200, so that when the transmission rod 32 rotates, the second section of the limit rod 33 is driven to rotate, and then the first section located in the mounting portion 200 is driven to rotate, so that the first section can be pressed against or pressed against the steel frame 100 arranged in the mounting portion 200.

[0029] like Figure 1 , Figure 3 As shown, the angle between the first section and the second end is an obtuse angle, so that it is easier for the second section to be pressed against the steel frame 100 when the first section is subjected to force.

[0030] Similarly, regarding the connection between the transmission rod 32 and the connecting frame 20, in an embodiment provided in the present disclosure, as shown in FIG. Figure 1 , Figure 3As shown, the transmission rod 32 may include a third section and a fourth section that are interconnected, a second hinge hole is formed at the connection between the third section and the fourth section, a second hinge shaft 26 that protrudes from the connecting frame 20 is also provided on the connecting frame 20, the second hinge shaft 26 is passed through the second hinge hole, the third section is connected to the driving structure 31, and the fourth section is transmission-connected to the second section of the limiting rod 33, so that when the driving structure 31 drives the third section to rotate, it drives the fourth section to rotate, and then drives the second section and the first section that are transmission-connected to the fourth section to rotate.

[0031] like Figure 1 , Figure 3 As shown, the limit rods 33 and the transmission rods 32 mentioned above can be two each, and correspondingly, the first hinge shaft 34 and the second hinge shaft 26 can also be two each. The two limit rods 33 are symmetrically arranged on both sides of the connecting frame 20, and the two transmission rods 32 are symmetrically arranged on both sides of the connecting frame 20. In this way, the two transmission rods 32 can simultaneously drive the two limit rods 33 to stop and limit the steel frame 100 from both sides of the connecting frame 20, thereby further improving the fixing and limiting effects of the steel frame 100.

[0032] In addition, the present disclosure does not limit the specific structure and driving method of the above-mentioned driving structure 31. For example, in an exemplary embodiment provided by the present disclosure, the above-mentioned driving structure 31 can be a motor, which can drive the transmission rod 32 to rotate when the motor is running, thereby realizing the driving of the limit rod 33. Alternatively, the above-mentioned driving structure 31 can also be a telescopic rod, which can realize the forward and reverse rotation of the transmission rod 32 through telescopic operation, thereby realizing the driving of the limit rod 33.

[0033] Alternatively, in another embodiment provided by the present disclosure, Figures 2 to 3 As shown, the driving structure 31 includes a first fastening bolt 310, a connecting hole 320 is formed at one end of the transmission rod 32 away from the steel frame 100, and a first threaded hole 230 is formed on the connecting frame 20. The first fastening bolt 310 is passed through the connecting hole 320 and is threadedly connected in the first threaded hole 230. In this way, when it is necessary to fix, limit, and stop the steel frame 100 disposed in the mounting portion 200, the first fastening bolt 310 can be passed through the connecting hole 320 and the first threaded hole 230, and the first fastening bolt 310 can be screwed to adjust the depth of the first fastening bolt 310 in the first threaded hole 230, and the first fastening bolt 310 is locked to continuously enter the first threaded hole 230, and the head of the first fastening bolt 310 is gradually pressed against the end of the transmission rod 32 away from the steel frame 100, so that the other end of the transmission rod 32 rotates relative to the connecting frame 20, and the limiting rod 33 is driven.

[0034] The present disclosure does not limit the connection method between the connecting frame 20 and the embedded part 10. For example, the connecting frame 20 can be connected to the embedded part 10 by welding, riveting or other non-detachable methods, or by detachable methods. For example, in an exemplary embodiment provided by the present disclosure, Figures 1 to 3 As shown, the wall connecting device may further include a second fastening bolt 40, a second threaded hole 110 is provided on the connecting wall 11 of the embedded part 10, a first through hole 22 is provided on the connecting frame 20, and the second fastening bolt 40 passes through the first through hole 22 and is locked in the second threaded hole 110. The second fastening bolt 40 is passed through the first through hole 22, and the second fastening bolt 40 is screwed, and the second fastening bolt 40 can be screwed into the second threaded hole 110 until the head of the second fastening bolt 40 presses the connecting frame 20 against the connecting wall 11.

[0035] Alternatively, the connecting frame 20 and the embedded part 10 can also be connected by snapping, that is, a snap-in block is formed on one of the connecting walls 11 of the connecting frame 20 and the embedded part 10, and a snap-in groove is formed on the other of the connecting walls 11 of the connecting frame 20 and the embedded part 10. The snap-in block is snapped into the snap-in groove to achieve the connection between the connecting frame 20 and the embedded part 10.

[0036] In order to further improve the connection stability and connection strength between the connecting frame 20 and the embedded part 10, optionally, as Figures 1 to 3 As shown, the connecting frame 20 may further include a positioning member 23 , which is formed as a cylindrical structure having a second through hole inside. The second fastening bolt 40 passes through the second through hole and the first through hole 22 in sequence and is locked in the second threaded hole 110 . In this way, when the second fastening bolt 40 is used to fasten the connecting frame 20 and the embedded part 10, the second fastening bolt 40 can be first passed through the second through hole and the first through hole 22 in sequence, and the second fastening bolt 40 can be threadedly connected to the second threaded hole 110 by screwing. At this time, due to the presence of the positioning member 23, the end of the positioning member 23 close to the connecting frame 20 is against the connecting frame 20, that is, the positioning member 23 always maintains a vertical state with the end face of the connecting frame 20. In this way, under the action of the positioning member 23, the second fastening bolt 40 can be guided, positioned and anti-deflected during the screwing process, so that the second fastening bolt 40 can always be screwed into the second threaded hole 110 at a perpendicular angle to the end face of the connecting frame 20, avoiding the problem of insufficient preload or damage or deformation of the second threaded hole 110 due to the tilt or misalignment of the second fastening bolt 40.

[0037] In order to further improve the stability of the above-mentioned wall connecting device, in an embodiment provided in the present disclosure, as Figures 1 to 3As shown, the first threaded hole 230 is formed on the positioning member 23. On the one hand, the first threaded hole 230 formed on the positioning member 23 can provide a fulcrum for fixing the first fastening bolt 310, and since there is no need to open the hole 21 on the connecting frame 20, it can also avoid damaging the strength of the connecting frame 20, affecting the connection, support effect and rigidity of the connecting frame 20. On the other hand, it is precisely because the first threaded hole 230 is formed on the positioning member 23 that after the first fastening bolt 310 is screwed into the first threaded hole 230, the first fastening bolt 310 can also play a role in fixing and limiting the positioning member 23, so that the positioning member 23 can remain in a fixed state before and after the second fastening bolt 40 is installed, avoiding the tilting and misalignment of the second fastening bolt 40 during the installation process due to the change in the position of the positioning member 23, and further improving the positioning accuracy of the positioning member 23.

[0038] In addition, because the positioning member 23 cannot rotate around its own axis under the limiting action of the first fastening bolt 310, it can also avoid the second fastening bolt 40 from loosening or even falling off due to the rotation of the positioning member 23, thereby further improving the connection stability between the second fastening bolt 40 and the embedded part 10.

[0039] In order to further prevent the second fastening bolt 40 from loosening, a plurality of first tooth grooves can be provided on the end surface of the end where the head of the second fastening bolt 40 contacts the positioning member 23, and a plurality of second tooth grooves can be provided on the end surface where the positioning member 23 contacts the head of the second fastening bolt 40. When the second fastening bolt 40 is tightened, the head of the second fastening bolt 40 is pressed against the positioning member 23, and the second tooth grooves are meshed with the first tooth grooves, so that the second fastening bolt 40 cannot rotate relative to the positioning member 23. In this way, when the first fastening bolt 310 is tightened to form After the positioning member 23 with the first threaded hole 230 is installed, under the limiting action of the first fastening bolt 310, the positioning member 23 cannot rotate around its own axis. Similarly, due to the limiting action of the first tooth groove set on the second fastening bolt 40 and the second tooth groove set on the positioning member 23, the second fastening bolt 40 cannot rotate around its own axis, further locking the second fastening bolt 40, further improving the stability of the second fastening bolt 40, and preventing the second fastening bolt 40 from loosening or falling off due to external force or other factors during long-term fastening.

[0040] Alternatively, in other embodiments provided in the present disclosure, the first threaded hole 230 may also be formed on the connecting frame 20 or the connecting wall 11 , and both of them can realize driving the transmission rod 32 when the first fastening bolt 310 is screwed.

[0041] In order to improve the verticality between the positioning member 23 and the connecting frame 20, optionally, an opening groove 240 opening away from the connecting wall 11 can be formed on the connecting frame 20, and the inner diameter of the opening groove 240 is adapted to the outer diameter of the positioning member 23, the first through hole 22 is located in the opening groove 240, the positioning member 23 is partially inserted in the opening groove 240, and the second through hole is concentrically arranged with the first through hole 22. In this way, when tightening the second fastening bolt 40, the positioning piece 23 can be inserted into the opening groove 240. Since the inner diameter of the opening groove 240 is adapted to the outer diameter of the positioning piece 23, the positioning piece 23 can be inserted into the opening groove 240 as vertically as possible under the limiting and guiding action of the groove wall of the opening groove 240. In addition, the second through hole in the opening groove 240 is concentrically arranged with the first through hole 22. When the second fastening bolt 40 is inserted into the second through hole, under the limiting and guiding action of the inner wall of the second through hole, the second fastening bolt 40 can automatically fasten to the first through hole 22, which makes it easier to screw in the second fastening bolt 40.

[0042] In addition, precisely because the positioning member 23 is inserted into the open groove 240, during the process of tightening the second fastening bolt 40, it can also prevent the positioning member 23 from tilting or dislocating due to the interference of the second fastening bolt 40, thereby improving the positioning effect and fault tolerance.

[0043] The above-mentioned inner diameter of the opening groove 240 is adapted to the outer diameter of the positioning member 23, which means that the inner diameter of the opening groove 240 can be slightly larger than the outer diameter of the positioning member 23, and when the positioning member 23 is inserted into the opening groove 240, the positioning member 23 can have an interference fit with the opening groove 240, which to a certain extent fixes and guides the positioning member 23, and further facilitates the vertical insertion of the positioning member 23.

[0044] The present disclosure does not limit the specific structure and shape of the above-mentioned connecting frame 20, as long as it can achieve the connection between the embedded part 10 and the steel frame 100. For example, in an embodiment provided by the present disclosure, Figures 1 to 3As shown, optionally, the connecting frame 20 may include a first connecting plate 24 and two second connecting plates 25, the first connecting plate 24 is connected to the connecting wall 11 of the embedded part 10, the two second connecting plates 25 are arranged parallel and opposite to each other on the side of the first connecting plate 24 away from the connecting wall 11, and the first connecting plate 24 and the two second connecting plates 25 together form a mounting portion 200. The two second connecting plates 25 can jointly support the steel frame 100, have higher strength and rigidity, thereby improving the supporting stability of the steel frame 100, and in addition, the mounting portion 200 formed by the first connecting plate 24 and the two second connecting plates 25 can also shield and protect the steel frame 100 arranged in the mounting portion 200 from the outside, so as to avoid corrosion, aging, and deformation caused by external factors (such as rain and sun) during long-term use, thereby further improving the service life.

[0045] For the embodiment in which the connecting frame 20 may include a first connecting plate 24 and two second connecting plates 25, as shown in FIG. Figure 1 to Figure 2 As shown, the above-mentioned opening 21 can be formed on the second connecting plate 25, and the first through hole 22 can be formed on the first connecting plate 24. In this way, when the second fastening bolt 40 is inserted into the first through hole 22 and the connecting frame 20 is fastened to the connecting wall 11, the first connecting plate 24 is arranged to fit the connecting wall 11, thereby increasing the contact area between the first connecting plate 24 and the embedded part 10, thereby improving the connection strength.

[0046] In addition, for the embodiment in which the connecting frame 20 may include a first connecting plate 24 and two second connecting plates 25, as shown in FIG. Figures 1 to 3 As shown, the second hinge shaft 26 can be arranged on the outside of the second connecting plate 25. In this way, the arrangement of the second hinge shaft 26 will not affect the connection between the first connecting plate 24 and the connecting wall 11, and can have enough rotation space.

[0047] It should be noted that the wall connection device provided in the present disclosure can be used in any field. For example, in one embodiment provided in the present disclosure, the wall connection device can be used to support a carport, especially a photovoltaic carport (a photovoltaic panel is arranged on the top of the carport).
