[0043] Please refer to Figure 3 The wall-hanging fixing structure 10 provided by the embodiment of the present application will be described. The wall-hanging fixing structure 10 comprises:

[0044] The first seat body 1 comprises a first clamping part 11 and a first connecting part 12;

[0045] The second seat body 2 comprises a second clamping part 21, the second clamping part 21 is movable relative to the first clamping part 11 in a first direction, and a clamping opening for fixing a wall-hanging household is formed between the first clamping part 11 and the second clamping part 21;

[0046] The elastic member 4 is connected between the first connecting part 12 and the second clamping part 21, and the elastic member 4 is configured to drive the second clamping part 21 to move close to the first clamping part 11 to fix the wall-hanging household.

[0047] In the embodiment, the first seat body 1 comprises the first clamping part 11 and the first connecting part 12, the first clamping part 11 and the first connecting part 12 can be connected as a whole as shown in Figure 3 , or can be a split structure. The second clamping part 21 is movable relative to the first clamping part 11 in a first direction, the first direction is actually a direction in which the first clamping part 11 and the second clamping part 21 move close to or away from each other, and the first clamping part 11 and the second clamping part 21 move relative to each other in the first direction, that is, the first clamping part 11 and the second clamping part 21 can move close to or away from each other. Specifically, the first clamping part 11 can be fixed, and the second clamping part 21 can move, or the first clamping part 11 can move, and the second clamping part 21 can be fixed, or both the first clamping part 11 and the second clamping part 21 can move.

[0048] The first seat body 1 and the second seat body 2 at least one of which needs to be fixed to the mounting wall of the wall-mounted household, and the mounting wall is determined according to the installation position of the wall-mounted household, such as a wall, a column, a door, a cabinet and the like. The fixing structure can be fixed to the first seat body 1, or the second seat body 2, or both of them, but if both of them are fixed, the first clamping part 11 can be moved relative to the first seat body 1 or the second clamping part 21 can be moved relative to the second clamping part 21, so that the first clamping part 11 and the second clamping part 21 can be moved relative to each other in the first direction. By the relative movement of the first clamping part 11 and the second clamping part 21, a clamping opening for fixing the wall-mounted household can be formed between the first clamping part 11 and the second clamping part 21 to clamp the wall-mounted household to be fixed. The embodiment is realized by the elastic force of the elastic member 4, and specifically the elastic member 4 is connected between the first connecting part 12 and the second clamping part 21, so that the second clamping part 21 is close to the first clamping part 11 along the first direction, thereby realizing the clamping of the wall-mounted household. The elastic member 4 can be a spring 41, a spring sheet and the like, and if the spring 41 is selected, a tension spring or a compression spring can be used, as long as it can provide clamping force for the clamping of the first clamping part 11 and the second clamping part 21. The specific structure of the first clamping part 11 and the second clamping part 21 can be designed according to the clamping requirement, for example, it can be a plate or block structure. As shown in the embodiment, the upper surface of the first clamping part 11 is arc-shaped, and the lower surface as the clamping surface is planar; the second clamping part 21 is a longer plate structure, which can provide more stable support. Figure 3

[0049] The wall-mounted fixing structure 10 of the embodiment can be used for fixing the wall-mounted shelf, and can also be used for fixing various household appliances, especially small decorative household appliances, and can also be used for fixing various wall decorations. When used, the wall-mounted household to be fixed is only needed to be clamped between the first clamping part 11 and the second clamping part 21 of the wall-mounted fixing structure 10, and after installation, it is not needed to be tightened or loosened with tools again, so that the quick installation and replacement of various wall-mounted households can be realized, which is convenient, fast, safe and not easy to fall off, solves the requirement of disassembling and assembling at any time for wall-mounted households of different materials and thicknesses, and is especially suitable for realizing modularization and DIY combination through quick splicing, increasing the user selectivity and differentiation. For example, for the wall-mounted shelf, transparent acrylic plates, glass or wood plates can be spliced into a certain shape, and then fixed by the wall-mounted fixing structure 10 of the embodiment, so that the wall-mounted shelf can be more easily disassembled and built faster. For example, the wall-mounted fixing structure 10 of the embodiment can be used to arbitrarily combine and fix the shelf, small household appliances and decorations, so as to achieve the desired effect of the user. Figures 16-17 The wall-mounted fixing structure 10 of the embodiment can be fixed on a plane, a convex corner or a concave corner of a wall corner, so as to realize the turning of the wall-mounted shelf according to the wall structure and maximize the use of the wall space. Among them, Figure 16 ​It is shown that the shelf is installed at the inside corner of the wall by using the wall-hanging fixing structure 10 of the embodiment, Figure 17 It is shown that the shelf is installed at the outside corner of the wall by using the wall-hanging fixing structure 10 of the embodiment.

[0050] Referring to Figure 8 In some embodiments of the present application, the first seat body 1 comprises a second connecting portion 13, and the first clamping portion 11 is connected with the second connecting portion 13; the second seat body 2 comprises a third connecting portion 22, and the second clamping portion 21 is connected with the third connecting portion 22; the second connecting portion 13 and the third connecting portion 22 are relatively slidable in the first direction, so that the second clamping portion 21 and the first clamping portion 11 are relatively movable in the first direction.

[0051] The first seat body 1 and the second seat body 2 can be completely separated or can be relatively slidable, and the latter has higher stability, so the embodiment belongs to the latter. The second connecting portion 13 of the first seat body 1 and the third connecting portion 22 of the second seat body 2 are relatively slidable in the first direction, that is, the second connecting portion 13 and the third connecting portion 22 are relatively movable in the first direction, and the first clamping portion 11 is connected with the second connecting portion 13, and the second clamping portion 21 is connected with the third connecting portion 22, so that the first clamping portion 11 and the first clamping portion 11 are relatively movable in the first direction. In the embodiment, the second connecting portion 13 and the third connecting portion 22 of the first seat body 1 and the second seat body 2 are relatively slidable, which can avoid interference with the clamping movement of the second clamping portion 21 and the first clamping portion 11 while improving the clamping stability.

[0052] A guide structure for movement in the first direction can be provided between the second connecting portion 13 and the third connecting portion 22 to ensure the stability of the relative movement of the two, and further ensure the stability of the clamping of the first clamping portion 11 and the second clamping portion 21. The specific shape of the second connecting portion 13 and the third connecting portion 22 can be designed according to requirements, for example, designed as a plate or a block, etc., and in the embodiment shown in Figure 3 The second connecting portion 13 and the third connecting portion 22 are both plate structures.

[0053] Referring to Figure 5 and 6 In some embodiments of the present application, the third connecting portion 22 is provided with a plug-in port 23, and a groove 24 is provided on both sides of the plug-in port 23 in the first direction, and the two sides of the second connecting portion 13 are respectively plugged into the grooves 24 on both sides of the plug-in port 23, the first connecting portion 12 is connected with the second connecting portion 13, and the first connecting portion 12 extends to the side of the second clamping portion 21 away from the first clamping portion 11 through the plug-in port 23, and the elastic member 4 is configured to push the second clamping portion 21 to be close to the first clamping portion 11.

[0054] The specific position of the first connecting portion 12 can be between the second clamping portion 21 and the first clamping portion 11, can be on the side of the second clamping portion 21 away from the first clamping portion 11, or can be on the side of the first clamping portion 11 away from the second clamping portion 21. When the first connecting portion 12 is on the side of the second clamping portion 21 away from the first clamping portion 11, it is more conducive to the arrangement of the elastic member, and the spring 41 can be more easily arranged between the first connecting portion 12 and the second clamping portion 21 to push the second clamping portion 21 to be close to the first clamping portion 11 to achieve clamping. However, when the first connecting portion 12 is on the side of the second clamping portion 21 away from the first clamping portion 11, because the second clamping portion 21 is between the first connecting portion 12 and the first clamping portion 11, the first connecting portion 12 is difficult to connect with the first clamping portion 11 by passing the second clamping portion 21, so that the first clamping portion 11, the first connecting portion 12 and the second connecting portion 13 are difficult to form the first seat body 1 of the integral structure. If the first clamping portion 11 and the first connecting portion 12 are connected by bypassing the second clamping portion 21 through the second connecting portion 13, the sliding fit of the third connecting portion 22 and the second connecting portion 13 will be limited. Therefore, in the embodiment, the third connecting portion 22 is provided with a plug-in interface 23, and the plug-in interface 23 is provided with a groove 24 on both sides in the first direction. The two sides of the second connecting portion 13 are respectively plugged into the grooves 24 on both sides of the plug-in interface 23. The groove 24 can play a guiding role to ensure the stability of the relative sliding of the second connecting portion 13 and the third connecting portion 22, and further improve the stability of clamping. The plug-in interface 23 not only forms the groove 24 matched with the second connecting portion 13 to enable the stable sliding fit of the third connecting portion 22 and the second connecting portion 13, but also enables the first connecting portion 12 on the side of the second clamping portion 21 away from the first clamping portion 11 to be connected with the second connecting portion 13 through the plug-in interface 23, while the second connecting portion 13 is connected with the first clamping portion 11, so that the first clamping portion 11, the first connecting portion 12 and the second connecting portion 13 are connected together to form the first seat body 1 of the integral structure, thereby reducing the number of parts and being more conducive to installation.

[0055] Referring to Figure 5 In some embodiments of the present application, the plug-in interface 23 comprises a first section and a second section arranged in sequence in the insertion direction of the second connecting portion 13. The grooves 24 on both sides of the first section are provided with a first cutout portion 25, so that the width of the first section is greater than the width of the second section, and the width of the first section gradually decreases in the insertion direction of the second connecting portion 13.

[0056] The plug-in interface 23 of the embodiment is divided into a first section and a second section, and the first section has a first cutout portion 25 on both sides. It should be noted that the first cutout portion 25 of the first section refers to a portion of the section that has a cutout-like shape, so that the width of the plug-in interface 23 of the portion is wider. Therefore, the first section is actually an enlarged section, and the width of the first section is greater than the width of the second section. The first section and the second section are arranged in sequence along the insertion direction of the second connecting portion 13. Therefore, the second connecting portion 13 first enters the first section and then enters the second section. The width of the first section is wider, so that the insertion of the second connecting portion 13 is easier, and the first connecting portion 12 can also pass through the first section better. The width of the first section gradually decreases along the insertion direction of the second connecting portion 13, so that the second connecting portion 13 can be better guided from the first section to the second section. The width of the second section is smaller than that of the first section, so that the second connecting portion 13 can be better combined with the groove 24, thereby ensuring the stability of the installation.

[0057] In addition, referring to Figure 7 In another embodiment of the present application, the second connecting portion 13 is plugged into the end of the plug-in interface 23, and a corresponding second cutout portion 15 can also be provided, so that the width of the second connecting portion 13 gradually decreases in the direction towards the end, thereby making the second connecting portion 13 easier to be inserted into the plug-in interface 23.

[0058] Referring to Figure 4 In some embodiments of the present application, the second connecting portion 13 is provided with a connecting structure 14 for connecting the mounting wall, and the projection of the connecting structure 14 on the third connecting portion 22 is located in the plug-in interface 23. When the wall-mounted fixing structure 10 is installed, one of the first seat body 1 and the second seat body 2 needs to be fixed to the wall surface, so as to fix the wall-mounted fixing structure 10. Since the third connecting portion 22 is provided with the plug-in interface 23, there is usually not enough space on it to set the connecting structure 14 for fixing to the wall surface without increasing the volume. In the embodiment, the connecting structure 14 is arranged on the second connecting portion 13, and the projection of the connecting structure 14 on the third connecting portion 22 is located in the plug-in interface 23, so that the space can be fully saved, and the volume of the entire wall-mounted fixing structure 10 can be reduced. In particular, in the case where the second connecting portion 13 is plugged into both sides of the plug-in interface 23, the balance of the force can be improved, and the stability of the installation can be ensured.

[0059] The connecting structure 14 can have different structures according to different mounting walls. For example, for wooden walls and painted walls, the connecting structure 14 can be a connecting hole for connecting screws or bolts; for ceramic tile walls and glass walls, the connecting structure 14 can be a connecting surface for gluing or a suction cup structure for suction, etc. For example, Figure 4The connection structure 14 shown is a connection hole for connecting an expansion screw. The connection structure 14 can also be used for multiple connection methods, such as both adhesive connection and screw connection.

[0060] Referring to Figure 9 In some embodiments of the present application, the elastic member 4 comprises a spring 41 and a guide positioning member, the second clamping portion 21 is located between the first clamping portion 11 and the first connecting portion 12, one end of the spring 41 abuts against the second clamping portion 21, and the other end abuts against the first connecting portion 12, and the guide positioning member is arranged along the first direction and restricts the spring 41 from extending and contracting along the first direction.

[0061] The elastic member 4 can be a tensile spring 41 or a compression spring 41, which provides clamping force for the first clamping portion 11 and the second clamping portion 21 through tension or thrust. In this embodiment, the second clamping portion 21 is located between the first clamping portion 11 and the first connecting portion 12, and the two ends of the spring 41 abut against the second clamping portion 21 and the first connecting portion 12 respectively, providing thrust for the second clamping portion 21, thereby achieving clamping. For the case of providing clamping force by the thrust of the spring 41, it is necessary to ensure the stability of the extension and contraction of the spring 41, and thus ensure the stability of the thrust provided by the spring 41. Therefore, the guide positioning member in this embodiment mainly plays a role of restricting and guiding the spring 41, ensuring the stable extension and contraction of the spring 41 along the first direction. For the case where the first connecting portion 12 is located on the side of the second clamping portion 21 away from the first clamping portion 11, one end of the spring 41 abuts against the second clamping portion 21, and the other end abuts against the first connecting portion 12, and the thrust of the spring 41 causes the second clamping portion 21 to move close to the first clamping portion 11 to achieve clamping.

[0062] The guide positioning member can adopt a cylindrical structure, a groove structure, etc. The cylindrical structure is usually a positioning column arranged along the first direction, and the spring 41 is sleeved on the positioning column to restrict the spring 41. The groove structure is usually a positioning groove arranged along the first direction, and the spring 41 is installed in the positioning groove, and the groove wall of the positioning groove restricts the spring 41.

[0063] For the specific structure of the guide positioning member, see Figure 12 In one embodiment of the present application, the guide positioning member comprises a first positioning column 42 and a second positioning column 43, the first positioning column 42 is connected with the first connecting portion 12, and the second positioning column 43 is connected with the second clamping portion 21, one end of the spring 41 is sleeved on the first positioning column 42, and the other end of the spring is sleeved on the second positioning column 43.

[0064] In the embodiment, the spring 41 passes through the first positioning column 42 and the second positioning column 43. The first positioning column 42 is connected to the first connecting part 12, and the second positioning column 43 is connected to the second clamping part 21. The two ends of the spring 41 are sleeved on the first positioning column 42 and the second positioning column 43 respectively, and the two ends of the spring 41 are constrained, so that the spring 41 is compressed in the first direction without bending. The first positioning column 42 and the first connecting part 12 can be connected in a threaded connection, a screw connection, welding, one-piece forming, etc. The second positioning column 43 and the second clamping part 21 can be connected in a threaded connection, a screw connection, welding, one-piece forming, etc. However, in order to facilitate the installation of the spring 41, at least one of the first positioning column 42 and the second positioning column 43 is preferably connected in a detachable connection mode. For example, Figure 12 In the embodiment shown, the first positioning column 42 has a thread, and is connected to the first connecting part 12 in a threaded connection. When installing the spring 41, the spring 41 can be sleeved on the second positioning column 43 at one end, and then the first connecting part 12 is screwed into the first positioning column 42, so that the first positioning column 42 is inserted into the other end of the spring 41, and the installation is completed.

[0065] Referring to Figure 13 In another embodiment of the present application, the guide positioning member includes a third positioning column 44, the third positioning column 44 passes through the first connecting part 12 and is movable relative to the first connecting part 12 in the first direction, the third positioning column 44 is connected to the second clamping part 21, and the spring 41 is sleeved on the third positioning column 44.

[0066] In the embodiment, the third positioning column 44 is not directly connected to the first connecting part 12, but is connected to the second clamping part 21, passes through the first connecting part 12, and is movable relative to the first connecting part 12 in the first direction. Therefore, the third positioning column 44 can move synchronously with the second clamping part 21 relative to the first connecting part 12, and the moving direction is along the first direction, that is, the movement direction of the second clamping part 21. The spring 41 is sleeved on the third positioning column 44, and the two ends of the spring 41 abut against the second clamping part 21 and the first connecting part 12 respectively, so as to constrain the spring 41, so that the spring 41 is compressed in the first direction without bending.

[0067] Because the spring 41 is to be in abutment with the first connecting part 12, and the spring 41 is sleeved on the third positioning column 44, the third positioning column 44 needs to pass through the first connecting part 12. In order to make the third positioning column 44 pass through the first connecting part 12, a hole can be opened in the first connecting part 12, and the diameter of the hole needs to be larger than the diameter of the third positioning column 44, so that the third positioning column 44 can pass through. In addition, a U-shaped groove can also be formed on the first connecting part 12, and the third positioning column 44 passes through the first connecting part 12 from the U-shaped groove, so that the spring 41 sleeved on the third positioning column 44 can be in abutment on the first connecting part 12. In order to facilitate the installation of the spring, the third positioning column 44 is also preferably detachably connected with the second clamping part 21. For example, Figure 13 In the embodiment shown, the third positioning column 44 adopts a long screw rod. When the spring 41 is installed, the spring 41 is placed between the first connecting part 12 and the second clamping part 21, and then the third positioning column 44 passes through the spring 41 and is threadedly connected with the second clamping part 21, so that the installation of the spring 41 is realized.

[0068] Referring to Figures 1-3 In some embodiments of the present application, the wall hanging fixing structure 10 further comprises an outer shell 3 connected with the second seat body 2 and covering at least the elastic member 4. The outer shell 3 covering the elastic member 4 can play an aesthetic role, and can also protect the elastic member 4 from external accidental impact to affect the elasticity of the elastic member 4. In addition, the outer shell 3 can also increase the structural strength to some extent, so that the wall hanging household is more stable. The outer shell 3 and the second seat body 2 can be connected by various ways such as screws, buckles 31, etc. In addition to covering the elastic member 4, the outer shell 3 can also be designed in size and coverage according to needs, for example, covering the entire plug-in interface 23, thereby better improving the aesthetic degree.

[0069] As Figures 4-11 The installation method of the wall hanging fixing structure 10 of an embodiment of the present application is as follows. First, as Figure 4 shown, the first seat body 1 is fixed on the wall surface by screwing the screw 51 through the countersunk screw hole and cooperating with the plastic expansion tube 52. For wooden walls, the screw 51 can be directly fixed, and in addition, other fixing methods such as gluing can also be used according to needs.

[0070] As Figures 5-8As shown, after the first seat body 1 is fixed, the second seat body 2 is sleeved on the first seat body 1 through the insertion interface 23, so that the second seat body 2 can slide along the groove 24 relative to the first seat body 1, and the distance between the first clamping part 11 and the second clamping part 21 is changed to clamp and adapt to clamping objects of different thicknesses. In order to prevent the first connecting part 12 on the first seat body 1 from interfering when being inserted into the insertion interface 23, the groove 24 on the first section has a first cutout part 25 on both sides, and the first connecting part 12 is moved to the upper part of the groove 24 through the first section, and then the second connecting part 13 of the first seat body 1 is inserted into the insertion interface 23 of the second seat body 2. At the same time, the presence of the first cutout part 25 on the second seat body 2 and the second cutout part 15 on the first seat body 1 is beneficial to the insertion of the first seat body 1 and the second seat body 2.

[0071] As shown in Figures 9-10 After the first seat body 1 and the second seat body 2 are inserted and combined, the spring 41 is installed between the first connecting part 12 of the first seat body 1 and the second clamping part 21 of the second seat body 2, and the first positioning column 42 is aligned with the spring 41 and installed on the first connecting part 12, so that the spring 41 is constrained, and the relative sliding of the first seat body 1 and the second seat body 2 will not shake.

[0072] When the wall-mounted household is to be installed, the second seat body 2 is pressed down, the deformation of the spring 41 increases, the clamping opening between the first clamping part 11 and the second clamping part 21 becomes larger, and after the clamping part of the wall-mounted household is placed in the clamping opening, the external force is removed, the second clamping part 21 moves close to the first clamping part 11 under the action of the spring 41, and clamps and fixes the wall-mounted household together with the first clamping part 11. In this process, the clamping force is provided by the spring 41, and the spring 41 can be tightly pressed without shaking.

[0073] As shown in Figure 11 By installing the outer shell 3 on the second seat body 2, the structures inside the second seat body 2, including the first connecting part 12, the spring 41, the insertion interface 23 and the like, are covered. Figure 3 The outer shell 3 in the embodiment is connected by buckling the buckle 31 with the buckle groove 26 of the second seat body 2, so that the overall structure is complete and firm. The outer shell 3 can be installed after the wall-mounted household is installed, or the outer shell 3 can be installed first and then the wall-mounted household is installed.

[0074] When the wall-mounted household is replaced, only the second seat body 2 needs to be pressed down, the old wall-mounted household is taken out, and then the new wall-mounted household is inserted into the clamping opening. The specific material of the wall-mounted fixing structure 10 can be plastic, metal, or other materials. For example, in an embodiment, the first seat body 1, the second seat body 2 and the outer shell 3 are all made of stainless steel, and the overall bearing weight is about 10-15KG, which can clamp various wall-mounted households.

[0075] Please refer to Figures 14-15The wall-hanging fixing structure 10 in the embodiments of the present application can be used to fix shelves, household appliances, and various decorations, etc., among which the fixing of shelves is the most convenient. Therefore, based on the above-mentioned fixed shelves, the present application further provides a shelf, which comprises a shelf body 6 and the above-mentioned wall-hanging fixing structure 10, and at least part of the shelf body 6 is arranged between the first clamping part 11 and the second clamping part 21. It should be noted that although a single set of wall-hanging fixing structure 10 can achieve the fixing of the shelf body 6 to a certain extent, the stability of a single set of wall-hanging fixing structure 10 is relatively poor. Therefore, the shelf usually comprises at least two sets of the above-mentioned wall-hanging fixing structure 10, that is, the shelf body 6 is installed on the wall structure through at least two sets of wall-hanging fixing structure 10, and the shelf body 6 can have various shapes, for example, it can be the most common plate shape, or a frame shape, a cage shape structure, or even other shapes of animals and plants. As long as the shelf body 6 is clamped on the clamping opening of the wall-hanging fixing structure 10, the fixing can be achieved. For example Figure 15 and 16 In the embodiments shown in Figs. 8 and 9, the wall-hanging fixing structure 10 clamps the wall plate to form a shelf, and various ornaments such as books, magazines, and photo frames can be safely placed on the shelf. Figures 16-17 As shown in Fig. 10, the wall plate of the shelf body 6 can be designed to be adapted to the internal corner or the external corner of the wall, and the wall-hanging fixing structure 10 in the embodiments can achieve good fixing.

[0076] The above are only the preferred embodiments of the present application, and are not used to limit the present application, and any modifications, equivalent replacements, and improvements made within the spirit and principles of the present application shall be included in the protection scope of the present application.
