Description

Technical Field

[0002] A detachable solid wood chair using a mortise and tenon structure is a piece of furniture that combines traditional craftsmanship with modern design concepts. The mortise and tenon structure is a connection method in traditional Chinese woodworking techniques. A firm connection is formed by precise cutting and matching of wood. No metal nails or screws are required, which makes it more beautiful. However, the connection of the mortise and tenon parts in the current solid wood chairs is very precise. When the connection is broken and cannot be used anymore, it is necessary to purchase new ones. The existing mortise and tenon connections are generally cut by hand by professional craftsmen, which takes time and cost to purchase, and cannot be produced in large quantities. In addition, the installation and disassembly processes are also more troublesome. Utility Model Content

[0003] The purpose of the utility model is to provide a detachable solid wood chair using a mortise and tenon structure in order to solve the above-mentioned problem.

The transverse support plate 2 is symmetrically arranged up and down, but only the rear side of the lower transverse support plate 2 is provided with a convex plate 17, and the bottom side is provided with a receiving plate 11, which is intended to fix the transverse plate 5 without affecting the user experience of sitting on the transverse plate 5. The shielding connecting plate 3 is used to support the transverse support plate 2 to a certain extent, so that the two transverse support plates 2 are more stable, and the receiving plate 11 is used to fix and support the first connecting clamp plate 12;

[0028] The front and rear sides of the cross plate 5 are penetrated by multiple convex plates 17, and the two main support plates 1 are penetrated by a perforated limiting rod 9. A connecting fixing plate 7 is fixedly arranged on the front and rear sides between the cross plate 5 and the inclined plate 6. A semicircular groove 15 is opened on one side of the inclined plate 6, and the perforated limiting rod 9 is clamped on the inner side of the semicircular groove 15 of the inclined plate 6. The convex plate 17 fixes the cross plate 5, and the cross plate 5 can be clamped on the inner side of the transverse support plate 2 to play a supporting role. The perforated limiting rod 9 corresponds to the semicircular groove 15 in the inclined plate 6, which makes the installation of the inclined plate 6 more convenient and quick. By connecting the fixing plate 7, after the normal installation of the cross plate 5 is completed, the position of the inclined plate 6 can be quickly fixed by connecting the fixing plate 7 and the perforated limiting rod 9.
