Description

Technical Field

[0001] The utility model relates to the technical field of furniture decoration, in particular to a detachable fixture. Background Art

[0002] For various types of interior space designs, furniture decoration objects such as curtains, sliding doors or partitions are often used to add a sense of hierarchy and variability to the interior space, and also provide practical functions in various private or public fields, such as dining, entertainment, living, exhibitions or work, etc.

[0003] On the other hand, modern people are also paying more and more attention to how to reduce the interference of noise in the interior space and thus improve the comfort of the overall space.

[0004] However, if noise reduction is achieved by adding general sound-absorbing plates (for example, acrylic plates, wooden plates or foam plates), this method not only has the problems that general sound-absorbing plates are usually bulky and heavy, but also has the construction problem that it is not easy to combine with existing furniture decoration objects; in addition, once the design style of general sound-absorbing plates is made, it is not easy to make adaptive adjustments and changes in the follow-up due to changes in the use environment.

[0005] Therefore, if the general sound-absorbing plate can be changed to a new type of sound-absorbing structure body that can provide good sound insulation effect, is lightweight and can make adaptive adjustments and changes according to the changes in the use environment (for example, a porous fibrous structure body of a rigid sound-absorbing plate), and its original use as only a sound-absorbing plate is changed to be combined and used with furniture decoration objects such as curtains, sliding doors or partitions (for example, directly used to replace some components such as curtain fabrics, door panels or partitions), then the above multiple purposes can be satisfied at the same time.

[0006] One of the key points in the implementation is that in terms of the installation structures of current known furniture decoration objects such as curtains, sliding doors or partitions, some components such as curtain fabrics, door panels or partitions often need to be matched with slide rail components (for example, including slide rails and multiple sliding parts installed in the slide rails) that are fixed to existing interior structure bodies. In other words, if the above new type of sound-absorbing structure body after replacement cannot cooperate with the existing slide rail components, it will be impossible to smoothly promote and apply this new type of sound-absorbing structure body in the field of combined use with furniture decoration objects; of course, how to more conveniently disassemble and install the above new type of sound-absorbing structure body is also another key point of technology that must be improved during implementation.

[0044] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0045] Please refer to Figure 1 , which is a structural schematic diagram of one embodiment of the detachable fixture of this application; the detachable fixture 11 in this case can connect the rigid sound-absorbing structure body 12 with the slide rail assembly 13 to form an integral furniture decoration object 10; wherein, the slide rail assembly 13 has a slide rail 131 and a plurality of sliding parts 132 installed in the slide rail 131.

[0046] Of course, the aforementioned furniture decoration object 10 includes at least one of curtains, movable sliding doors, and movable partitions, and is not limited thereto; wherein, Figure 1 In the specific embodiment of the furniture decoration object 10 shown, a curtain is used as an example for illustration.

[0047] Secondly, regarding Figure 1 the connection relationship among the detachable fixture 11, the rigid sound-absorbing structure body 12, and the slide rail assembly 13 in Figure 1 , for example, it can be implemented in the following manner: one side of the detachable fixture 11 is connected to the rigid sound-absorbing structure body 12 in a detachable manner, and as for the other side of the detachable fixture 11, it can be selected to be disassembled (as shown in

[0048] In addition, the rigid sound-absorbing structure 12 can be a porous fibrous structure of a rigid sound-absorbing panel body; wherein, the porous structure in the porous fibrous structure is composed of materials with characteristics such as elastic resilience and friction. For example, the materials can be selected from: one or a combination of a polyurethane structure, a glass fiber structure (Glass Fiber Panel, Glass Fiber Board), a polyester fiber structure, a polyester composite cotton structure, and a felt structure.

[0049] For example, in this case, the rigid sound-absorbing structure 12 can be a rigid polyester fiber sound-absorbing panel body, and this case is not limited thereto.

[0050] The thickness of the rigid sound-absorbing structure 12 depends on the actual application scenario; for example, to enhance the sound absorption rate or noise reduction effect, the thickness of a single rigid sound-absorbing structure 12 can be increased to at least 9 millimeters (mm) to 12 millimeters (mm) or more. Of course, in another embodiment, the rigid sound-absorbing structure 12 can also be composed of multiple rigid sound-absorbing structures with a relatively thin thickness stacked together, and in this way, the degree of variation in the shape can be increased; this case does not limit various variations of the rigid sound-absorbing structure 12.

[0051] Please refer to Figure 2A 、 Figure 2B 、 Figure 2C and Figure 2D , which are respectively schematic structural diagrams of four different perspectives of specific embodiments of the detachable fixture in this case; at the same time, refer to Figure 1 , which is a schematic structural diagram showing the assembly relationship between the specific embodiment of the detachable fixture in this case and the Figure 3 sound-absorbing structure in Figure 1 ; in addition, please further refer to Figure 1 , which is a schematic structural diagram of the slide rail assembly for providing a specific embodiment of the detachable fixture to be detachably mounted thereon in this case. Figure 4 In Figure 1 ; at the same time, refer to

[0052] In Figure 1 、 Figure 2A 、 Figure 2B 、 Figure 2C and Figure 2D 、 Figure 3 and Figure 4In the [description], a specific implementation of the detachable fixture 11 may include a fixture main body 111, which is combined with the slide rail assembly 13; and two vertical clamping arms 1131 and 1132, which are arranged corresponding to each other and connected to the fixture main body 111, and the vertical clamping arms 1131 and 1132 are detachably combined with the rigid sound-absorbing structure 12; wherein, the two vertical clamping arms 1131 and 1132 are arranged corresponding to each other and at intervals, and the end of any one of the vertical clamping arms extends to form a first engaging portion 11311 and 11321, and the first engaging portions 11311 and 11321 can be respectively correspondingly engaged with a second engaging portion 121 on one side of the rigid sound-absorbing structure 12 (as shown in Figure 3 ), so that the fixture main body 111 and the rigid sound-absorbing structure 12 are connected as a whole.

[0053] Wherein, the first engaging portions 11311 and 11321 of any one of the vertical clamping arms 1131 and 1132 are hook portions (as shown in Figure 2A ), and the second engaging portion 121 of the rigid sound-absorbing structure 12 is a groove (as shown in Figure 3 ).

[0054] Wherein, the hook portions 11311 and 11321 on the two vertical clamping arms 1131 and 1132 are arranged facing each other (as shown in Figure 2A ); in another method, the hook portions 11311 and 11321 are arranged back to back (not shown in the figure), and the present application is not limited thereto.

[0055] Of course, the first engaging portions 11311 and 11321 of any one of the vertical clamping arms 1131 and 1132 are grooves (not shown in the figure), and the second engaging portion 121 of the rigid sound-absorbing structure 12 is a hook portion (not shown in the figure), and the present application is not limited thereto.

[0056] In another embodiment, the specific implementation of the detachable fixture 11 in this case is not limited to the above content. For example, the vertical clamping arms 1131 and 1132 can be changed to any two corresponding side edges of the fixture main body 111 (not shown in the figure), so that these vertical clamping arms 1131 and 1132 are not on the same surface, and the present application is not limited thereto.

[0057] The first surface 1111 is the upper surface of the fixture main body 111, and the second surface 1112 is the lower surface of the fixture main body 111.

[0058] The specific implementation of one of the above two vertical clamping arms 1131 and 1132, for example, the two vertical clamping arms 1131 and 1132 can be two vertical sheets (as shown in Figures 2B to 2D ), and a receiving space 1133 is formed between them at intervals, and the two vertical clamping arms 1131 and 1132 clamp and combine the rigid sound-absorbing structure 12 in the receiving space 1133.

[0059] Wherein, the included angle between any one of the two vertical clamping arms 1131 and 1132 and the second surface 1112 (e.g., the lower surface) of the fixture body 11 can be set to be equal to or less than 90 degrees. In this way, the two vertical clamping arms 1131 and 1132 can clamp and combine the rigid sound-absorbing structure body 12 in the receiving space 1133 through their own elastic deformation; that is, the detachable fixture 11 in this case can easily perform disassembly or assembly operations on the two vertical clamping arms 1131 and 1132 and the rigid sound-absorbing structure body 12 quickly without using any locking means (e.g., screws) (as Figure 3 shown).

[0060] In addition, the support portion 112 is a structure extending in a direction away from the vertical clamping arms 1131 and 1132 on the first surface 1111 of the fixture body 111.

[0061] Wherein, the support portion 112 has a third coupling portion 1121, and the third coupling portion 1121 is linked to the Figure 1 and Figure 4 shown slide rail assembly 13; taking Figure 4 as an example, any one of the plurality of sliding members 132 has a pivoting portion 1321, and the sliding member 132 is installed in the slide rail 131 through the pivoting portion 1321; in addition, any one of the plurality of sliding members 132 also has a fourth coupling portion 1322 (such as the Figure 4 shown hook structure), and the sliding member 132 is detachably combined with the third coupling portion 1121 of the support portion 112 through the fourth coupling portion 1322.

[0062] In addition, to enable the third coupling portion 1121 of the support portion 112 to be more smoothly connected to the fourth coupling portion 1322 (such as the Figure 4 shown hook structure), each sliding member 132 has an inclined surface 1323, which facilitates the detachable connection between the third coupling portion 1121 of the support portion 112 and the fourth coupling portion 1322 of any one of the sliding members 132.

[0063] In summary, through the above solution of the present application, the detachable fixture 11 can be used to quickly integrate the rigid sound-absorbing structure body 12 belonging to the rigid polyester fiber sound-absorbing board body and the slide rail assembly 13, simultaneously achieving the goals of assembly cost and assembly convenience, and improving the design flexibility of interior decoration and the effect of reducing noise.

[0064] In addition, it can be understood that the foregoing various embodiments are only exemplary descriptions of the present utility model. On the premise that there is no conflict in technical features, no contradiction in structure, and no violation of the invention purpose of the present utility model, the technical solutions of the various embodiments can be arbitrarily combined and used.

[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
