Description

Technical Field

[0001] This utility model belongs to the field of wood product processing, and specifically relates to a splicing and fixing device for wooden furniture. Background Technology

[0002] Wooden furniture refers to furniture made primarily of wood, and it is widely popular due to its natural texture, aesthetic appeal, and environmental friendliness. Wooden furniture includes various types of furniture, such as beds, tables, chairs, cabinets, and bookshelves, playing an irreplaceable role in people's daily lives.

[0003] Due to the limited strength of wood, wooden furniture requires numerous splicing and fastening components in areas with concentrated loads or large spans to increase overall structural strength and prevent deformation. However, these splicing and fastening components are mostly made of wood, which not only has relatively poor strength but also tends to loosen over time, causing abnormal noises during use and resulting in a very poor user experience. In severe cases, they may fail completely, losing their splicing and fastening function and reducing the lifespan of the wooden furniture. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The following will refer to the appendix... Figures 1-6 This application will be described in detail with reference to the embodiments.

[0022] like Figure 1 , Figure 2 As shown, a splicing and fixing device for wooden furniture includes an adjusting shaft device 5 rotatably mounted in the middle of a fixed square tube device 2. The adjusting shaft device 5 is perpendicular to the central axis of the fixed square tube device 2. Clamping devices 3 are symmetrically slidably connected to both ends of the fixed square tube device 2. The clamping devices 3 are connected to the support legs 1 of the furniture. A spring device 6 is provided between the clamping devices 3. A steel wire rope 4 is fixedly connected between the two clamping devices. The middle section of the steel wire rope 4 is fixedly connected to the adjusting shaft device 5. Rotating the adjusting shaft device 5 tightens the steel wire rope, bringing the two clamping devices 3 closer together and tightening and fixing the support legs 1 of the furniture.

[0023] like Figure 3 , Figure 4 As shown, the fixed square tube device 2 includes a fixed shaft device 201. The fixed shaft device 201 has a sliding groove 2011 inside. The sliding groove 2011 has guide grooves 204 at both ends. The inner wall of the sliding groove 2011 is provided with a mounting platform 2012 in the middle. The outer wall of the fixed shaft device 201 has a rotating groove 203. The rotating groove 203 is correspondingly arranged with the mounting platform 2012.
