[0043] like Figure 1 As shown, the first embodiment of the present application proposes a connecting device for cooperating with a connecting piece 600 fixed on a wall. Figure 2 and Figure 3 As shown, the connecting device includes a housing 100, a first transmission member 200, a second transmission member 300 and a first locking member 400. The housing 100 has a first accommodating cavity 120, and the connecting member 600 can be inserted into the first accommodating cavity 120. The first transmission member 200 is rotatably connected to the housing 100. Specifically, as shown in FIG. Figure 3 As shown, the housing 100 further has a second accommodating chamber 130, which is communicated with the first accommodating chamber 120, and the first transmission member 200 is located in the second accommodating chamber 130. Figure 2 and Figure 3As shown, the second transmission member 300 and the first locking member 400 are located in the first accommodating cavity 120 and can both be sleeved on the connecting member 600. The second transmission member 300 cooperates with the first transmission member 200. The rotation of the first transmission member 200 can drive the rotation of the second transmission member 300. The second transmission member 300 can rotate relative to the first locking member 400. The first locking member 400 includes a main body 410 and a sliding block 420 slidably connected to the main body 410. The sliding block 420 is connected to the second transmission member 300. When the second transmission member 300 is driven by the first transmission member 200 to rotate along the set direction 700, it drives the sliding block 420 to slide radially relative to the main body 410 to the first position, as shown in FIG. Figures 3 to 6 As shown, the sliding blocks 420 are all located in the first position.

[0044] The second transmission member 300 is provided with an outwardly rotating guide groove 310. Figure 5 As shown, the guide groove 310 extends along the circumferential direction, and along the set direction 700, the distance from the guide groove 310 to the central axis of the second transmission member 300 gradually increases. Figure 5 In the embodiment shown, the setting direction 700 is a clockwise direction, and the distance from the guide groove 310 to the central axis of the second transmission member 300 gradually increases along the clockwise direction. Figure 2 、 Figure 4 and Figure 5 As shown, the sliding block 420 includes a guide post 421 extending axially along the first locking member 400, and the guide post 421 is inserted into the guide groove 310. When the second transmission member 300 rotates, the guide post 421 is driven by the groove wall of the guide groove 310 to move the sliding block 420 in the radial direction of the first locking member 400 in a direction close to the central axis or away from the central axis. In the initial state, the guide post 421 is located at the end of the guide groove 310 relatively far from the central axis. When the second transmission member 300 rotates clockwise, the position of the guide post 421 remains relatively unchanged. The position of the guide groove 310 rotates relative to the guide post 421, and the guide post 421 gradually moves from the end of the guide groove 310 relatively far from the central axis to the end relatively close to the central axis, so that the sliding block 420 can move to the first position where it cooperates with the connecting member 600 to limit its relative movement.

[0045] When the sliding block 420 is in the first position, it can limit the relative sliding displacement of the connecting device and the connecting member 600 along the axial direction. It should be noted that the "relative sliding displacement" mentioned here refers to the movement of the sliding block 420 relative to the connecting member 600 without rotation. Specifically, in some embodiments, such as Figure 2 and Figure 3As shown, the side of the sliding block 420 facing the connecting member 600 is provided with a threaded structure, and the outer peripheral surface of the connecting member 600 is provided with an external thread. When the sliding block 420 moves to the first position, the internal thread of the sliding block 420 engages with the external thread of the connecting member 600, thereby limiting the relative sliding displacement of the sliding block 420 and the connecting member 600 in the axial direction. Without further rotation of the first transmission member 200, the relative displacement of the sliding block 420 and the connecting member 600 is limited. It should be noted that if the first transmission member 200 is further rotated so that the sliding block 420 rotates synchronously with the first locking member 400 and the second transmission member 300, due to the threaded connection between the internal thread of the sliding block 420 and the external thread of the connecting member 600, the rotation of the sliding block 420 relative to the connecting member 600 can be converted into axial movement of the sliding block 420 relative to the connecting member 600, thereby achieving further locking.

[0046] In other embodiments, a groove is provided on the outer peripheral surface of the connecting member 600, and an inclined abutting surface is provided on the groove. The sliding block 420 is inserted into the groove and abuts against the inclined abutting surface. As the sliding block 420 moves radially toward the center axis, the reaction force of the abutting surface drives the connecting device to move on the connecting member 600, and then, the rotation of the first transmission member 200 is converted into axial movement of the connecting device.

[0047] During the installation process of the wall-mounted home improvement, a connecting piece 600 is provided on the wall. First, the connecting device is connected to the mounting portion of the wall-mounted home improvement, and the connecting device is tightly attached to the inner side of the mounting portion of the wall-mounted home improvement. Then, the wall-mounted home improvement and the connecting device are mounted on the connecting piece 600, and the outer side of the wall-mounted home improvement is tightly attached to the wall. Finally, the sliding block 420 is driven to move to the first position by a force-applying tool such as a hexagonal wrench, and the connecting device is fixed to the connecting piece 600. The mounting portion of the wall-mounted home improvement is clamped in the middle by the connecting device and the wall, achieving the initial clamping of the wall-mounted home improvement. Then, the first transmission member 200 is continued to be twisted to make the connecting device further move in the direction close to the wall, and then the mounting portion of the wall-mounted home improvement is tightly clamped between the connecting device and the wall, and the displacement of the wall-mounted home improvement is restricted, thereby completing the installation of the wall-mounted home improvement.

[0048] Based on the above, during the installation of the wall-mounted home improvement, the connecting device of the present application can be moved relative to the connecting member 600 to a preliminary locking position in an unlocked state, and then the sliding block 420 can be moved to the first position by a force-applying tool to switch the connecting device to the preliminary locking state. The relative rotation of the sliding block 420 and the connecting member 600 is then converted into relative movement of the connecting device relative to the connecting member 600, thereby completing the final locking. Compared with the locking structure of the nut and bolt, the locking stroke of the connecting device of the present application is smaller and more targeted. There is no need to start turning the first transmission member 200 when the connecting member is inserted into the connecting member 600. The operator only needs to apply force to rotate the first transmission member 200 after the connecting device moves to the preliminary locking position to achieve locking. During disassembly, the wall-mounted home improvement can be removed by simply rotating the first transmission member 200 a few times with a force-applying tool. Therefore, the connecting device of the present application can achieve rapid installation or disassembly of the connecting device and the connecting member 600.

[0049] In some embodiments, as Figure 7 As shown, the first locking member 400 further includes an abutting arm 430, one end of which is connected to the main body 410 to form a fixed end 431, and the other end extends to form a free end 432. The free end 432 can be elastically deformed relative to the fixed end 431. Along the direction from the fixed end 431 to the free end 432, the distance between the abutting arm 430 and the central axis of the first locking member 400 gradually increases. Figure 7 In the illustrated embodiment, the free end 432 and the fixed end 431 of the abutting arm 430 are sequentially arranged along the set direction 700, i.e., the distance between the abutting arm 430 and the central axis of the first locking member 400 gradually decreases. A limiting protrusion 110 is provided on the inner wall of the housing 100 at a position corresponding to the position of the abutting arm 430. The abutting arm 430 has a first state and a second state. In the first state, the abutting arm 430 can abut against the limiting protrusion 110 to limit the relative displacement between the first locking member 400 and the housing 100. Since the second transmission member 300 rotates relative to the housing 100, and thus the second transmission member 300 can rotate relative to the first locking member 400, in the second state, the abutting arm 430 can be deformed by force, so that the first locking member 400 can rotate synchronously with the second transmission member 300.

[0050] Specifically, during the locking operation of the connecting device, the second transmission member 300 rotates relative to the first locking member 400 to drive the sliding block 420 to move radially. In order to reduce the overall volume of the connecting device, as shown in FIG. Figure 3 and Figure 4As shown, the components within the housing 100 are compactly arranged, resulting in a relatively large contact area between the second transmission member 300 and the first locking member 400. Consequently, when the second transmission member 300 rotates relative to the first locking member 400, a certain amount of friction exists between the two. This friction may cause the first locking member 400 to rotate synchronously with the second transmission member 300, preventing the sliding block 420 from moving radially along the first locking member 400 and thus failing to complete the initial locking action. The abutment arm 430 of the present application serves to increase the rotational resistance of the first locking member 400. During the locking operation of the connecting device, the abutment arm 430 is in a first state, abutting against the limiting protrusion 110. The friction between the second transmission member 300 and the first locking member 400 is less than the resistance of the abutment arm 430 against the limiting protrusion 110, allowing the second transmission member 300 to rotate relative to the first locking member 400.

[0051] When the operator turns the first transmission member 200, after the sliding block 420 moves to the first position, the relative sliding displacement of the sliding block 420 and the connecting member 600 is restricted, the approximate position of the connecting device on the connecting member 600 is preliminarily determined, and the second transmission member 300 and the first locking member 400 are brought into contact (described later). The second transmission member 300 drives the first locking member 400 to rotate synchronously to further lock the connecting device. At this time, the driving force between the second transmission member 300 and the first locking member 400 is greater than the resistance of the abutment arm 430 against the limiting protrusion 110. The abutment arm 430 switches to the second state, deforms under the force, and its free end 432 moves in a direction close to the central axis of the first locking member 400. When the outer diameter of the abutment arm 430 is smaller than the inner diameter of the limiting protrusion 110, the limiting protrusion 110 cannot restrict the abutment arm 430, and the second transmission member 300 can rotate relative to the first locking member 400. After the abutting arm 430 slides over the highest point of the limiting protrusion 110, the abutting arm 430 recovers its elastic deformation and is no longer subject to resistance from the limiting protrusion 110. Figure 7 In the embodiment shown, a plurality of limiting protrusions 110 are provided on the inner circumferential surface of the housing 100. The limiting protrusions 110 are evenly distributed along the circumference. When the second transmission member 300 drives the first locking member 400 to rotate, the abutting arm 430 continuously switches between the first state and the second state, thereby giving the operator a noticeable sense of frustration. When the sliding block 420 moves to the first position, the abutting relationship between the second transmission member 300 and the first locking member 400 can be specifically generated by the guide slide column 421 and the groove wall of the guide groove 310, that is, as shown in FIG. Figure 5 As shown, after the guide slide 421 moves to abut against the groove wall of the guide groove 310, the second transmission member 300 drives the first locking member 400 to rotate, and the torque is transmitted by the guide slide 421; Figure 4 and Figure 6As shown, the abutment relationship between the second transmission member 300 and the first locking member 400 can also be established by the abutment protrusion 330 and the wall of the avoidance groove 440. Specifically, the second transmission member 300 extends an abutment protrusion 330 axially, and the first locking member 400 has an avoidance groove 440. The abutment protrusion 330 is inserted into the avoidance groove 440. When the second transmission member 300 rotates relative to the first locking member 400, the abutment protrusion 330 can move within the avoidance groove 440. When the sliding block 420 moves to the first position, the abutment protrusion 330 moves to the end of the avoidance groove 440 along the set direction 700 and abuts against the wall of the avoidance groove 440. The torque is transmitted to the first locking member 400 through the abutment protrusion 330 with higher strength to drive the first locking member 400 to rotate, replacing the guide slide column 421 with lower strength to abut against the groove wall of the guide groove 310 to transmit torque. This can avoid the guide slide column 421 from breaking when the torque is too large, and can improve the structural stability of the connecting device, thereby increasing the service life of the device.

[0052] like Figure 7 As shown, along the setting direction 700, the distance between the abutting arm 430 and the central axis of the first locking member 400 gradually decreases, and the limiting protrusion 110 sequentially includes a first surface 111 and a second surface 112 along the setting direction 700. The distance between the second surface 112 and the inner wall of the housing 100 gradually decreases, while the distance between the first surface 111 and the inner wall of the housing 100 gradually increases. Alternatively, the first surface 111 is perpendicular to the inner wall of the housing 100, and the angle between the first surface 111 and the inner wall of the housing 100 is greater than the angle between the second surface 112 and the inner wall of the housing 100. When the first locking member 400 and the second transmission member 300 rotate synchronously along the setting direction 700, the abutting arm 430 abuts against the first surface 111 of the limiting protrusion 110, and the abutment of the first surface 111 restricts the abutting arm 430, causing elastic deformation. It should be noted that the second transmission member 300 of the present application, driven by the first transmission member 200, can also rotate in the opposite direction of the set direction 700, driving the sliding block 420 to move in a direction away from the central axis to release the locking state between the connecting device and the connecting member 600, thereby achieving quick disassembly. When the second transmission member 300 rotates in the opposite direction of the set direction 700, the abutting arm 430 abuts the second surface 112 of the limiting protrusion 110, and the abutting arm 430 can provide a certain resistance to prevent the first locking member 400 from rotating synchronously with the second transmission member 300. The set sliding block 420 can move from a first position to a second position. In the second position, the connecting device can move relative to the connecting member 600, and the second transmission member 300 drives the first locking member 400 to rotate synchronously. At this time, the abutting arm 430 is restrained by the abutment of the second surface 112 and gradually elastically deforms until it slides past the junction of the second surface 112 and the first surface 111, then recovers its elastic deformation and emits a prompt sound.

[0053] In some embodiments, the housing 100 further includes a second accommodating cavity 130 for accommodating the first transmission member 200, and the connecting device further includes an adapter 500. The adapter 500 is sleeved on the first transmission member 200 and is rotatably connected to the first transmission member 200. The adapter 500 serves to restrict the first transmission member 200 from escaping from the second accommodating cavity 130. The adapter 500 is connected to the housing 100. Specifically, the adapter 500 and the housing 100 can be connected by a detachable structure such as a snap connection or a threaded connection, or can be connected by a non-detachable process such as fusion welding. Figure 2 In the illustrated embodiment, the adapter 500 is connected to the housing 100 via a snap-fit ​​mechanism. A first through-hole 510 is provided on the adapter 500, communicating with the second accommodating chamber 130. The end of the first transmission member 200 is provided with a slotted, cross-shaped, or hexagonal groove, enabling the first transmission member 200 to be twisted using a force-applying tool such as a slotted screwdriver, a Phillips screwdriver, or a hexagonal wrench. The force-applying tool extends through the first through-hole 510 into the second accommodating chamber 130 and is inserted into the groove at the end of the first transmission member 200, thereby driving the first transmission member 200 to rotate.

[0054] In some embodiments, the number of guide slots 310 and sliding blocks 420 is not limited, and can be as follows: Figure 5 The two shown may also be three or another number. When there are two or more (including two) guide grooves 310, each guide groove 310 is evenly distributed along the axial direction of the first locking member 400, and the first locking member 400 is provided with a corresponding number of sliding blocks 420. The multiple sliding blocks 420 can engage with the connecting member 600 from multiple directions. When the connecting device is subjected to pressure from the wall-mounted home improvement, the multiple sliding blocks 420 can distribute the load.

[0055] In some embodiments, a locking protrusion 311 is provided on the groove wall of the guide groove 310. Figure 5 As shown, the locking protrusion 311 is provided at the end of the guide groove 310 where the distance from the central axis of the second transmission member 300 is smaller, that is, at the end of the guide groove 310 where the guide column 421 is located when the sliding block 420 moves to the first position. This can limit the displacement of the sliding block 420 and prevent the sliding block 420 from retreating.

[0056] In some embodiments, reference Figure 6 As shown, the main body 410 of the first locking member 400 has a second through hole 411 extending axially therethrough, and the second through hole 411 is used for the connector 600 to pass through. The main body 410 also has a mounting groove 412 extending radially, the mounting groove 412 communicating with the second through hole 411, and the sliding block 420 is disposed in the mounting groove 412. The groove wall of the mounting groove 412 can guide the movement of the sliding block 420. Further, as Figure 2 and Figure 4 As shown, either the groove wall of the mounting groove 412 or the side wall of the sliding block 420 is provided with a guide protrusion 413, and the other is provided with a guide groove 422. Both the guide protrusion 413 and the guide groove 422 extend radially along the main body 410, and the guide protrusion 413 is embedded in the guide groove 422 to guide the movement of the sliding block 420.

[0057] In some embodiments, as Figure 2 As shown, the first transmission member 200 includes a first tooth portion 210, and the second transmission member 300 includes a second tooth portion 320. The rotation axis of the first transmission member 200 is arranged perpendicular to the rotation axis of the second transmission member 300. Through the engagement of the first tooth portion 210 and the second tooth portion 320, the rotation of the first transmission member 200 can drive the rotation of the second transmission member 300. Through the conversion of the first transmission member 200 and the second transmission member 300, force tools such as hexagonal wrenches and screwdrivers do not need to be inserted into the connecting device perpendicular to the axial direction of the connecting member 600 to complete the rotation locking operation. Instead, they can be inserted into the connecting device perpendicular to the axial direction of the connecting member 600 for locking operation. Taking the installation of a wall-mounted toilet as an example, the connecting device is located in the installation inner cavity of the toilet, and the installation space along the axial direction of the connecting member 600 is small, which is not conducive to the insertion or rotation of the force-applying tool. Through the conversion of the first transmission member 200, a through hole can be opened on the top surface or side of the toilet inner cavity to facilitate the insertion of the force-applying tool, and then facilitate the rotation of the force-applying tool. The operator can even reach into the inner cavity from the bottom of the toilet with one hand and complete the rotation locking operation to achieve the installation of wall-mounted home decoration.

[0058] In some embodiments, as Figure 2 As shown, the first accommodating cavity 120 has an opening along the axial direction for the second transmission member 300 and the first locking member 400 to be installed in the first accommodating cavity 120. The housing 100 further includes a side cover 140, which can be covered on the opening to seal the first accommodating cavity 120. The side cover 140 is detachably connected to the main body of the housing 100. Specifically, as shown in FIG. Figure 2 As shown, it is a snap connection.

[0059] The second embodiment of the present application proposes a wall-mounted home decoration component, including a wall-mounted home decoration and the connecting device mentioned in any of the above embodiments. The wall-mounted home decoration can be a hanging toilet, a washbasin or a storage cabinet, etc. The wall-mounted home decoration is fixedly connected to the wall to reduce the floor space and reduce sanitary dead corners. The wall-mounted home decoration includes a mounting portion, which is usually the wall of the wall-mounted home decoration close to the wall side, for example, the wall of the hanging toilet is attached to the wall, the innermost plate of the washbasin, etc. The mounting portion is provided with a mounting hole, and the connecting member 600 of the connecting device is passed through the mounting hole and connected to the wall. The wall-mounted home decoration component of this embodiment can complete the installation and locking operation quickly by using the connecting device to install the wall-mounted home decoration.

[0060] While the embodiments of the present invention have been described in detail above with reference to the accompanying drawings, the present invention is not limited to the embodiments described above. Various modifications may be made within the scope of knowledge possessed by a person skilled in the art without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof may be combined with one another unless there is a conflict.
