Technical Field

[0001] The utility model relates to the technical field of furniture manufacturing, in particular to a rectangular mortise and tenon wedge component. Background Art

[0002] Mortise and tenon play a dominant role in the structure of solid wood tables and are known as the "essence" of solid wood furniture. They have a history of thousands of years in my country. However, the structure of solid wood furniture tells us that mortise and tenon are the fit of the corresponding parts. At present, the convex and concave of solid wood furniture generally adopt over-fitting, and the convex can be inserted into the concave and pulled out, resulting in the loose structure of existing solid wood furniture after long-term use. As a result, solid wood furniture fails to achieve a physically integrated structure, and the general tenon structure is not easy to determine the position during installation. Utility Model Content

The preferred technical solution among the many technical solutions provided by the utility model can produce many technical effects as described below.

[0004] To achieve the above-mentioned purpose, the utility model provides a rectangular mortise and tenon wedge assembly, including a mortise body and a mortise wedge, the cross-section of the mortise body is rectangular, at least one end of the mortise body is provided with a mortise groove, the mortise wedge is adapted to the mortise groove, the retracted end of the mortise groove is connected to an elastic groove, and the outer side surfaces of the mortise body on both sides of the mortise groove are provided with grooves.

[0005] Optionally, the mortise groove is a tapered groove, the wide end of the tapered groove is opened on the end surface of the mortise body, and the tapered groove extends toward the middle of the mortise body and gradually converges.

[0006] Optionally, the elastic groove is configured as an arc groove connected to the converged end of the tapered groove.

[0007] Optionally, the tenon wedge is a tapered wedge.

[0008] Optionally, the length of the conical wedge is adapted to the conical groove, the thickness of the large end of the conical wedge is greater than the opening distance of the large end of the conical groove, and the thickness of the small end of the conical wedge is adapted to the opening distance of the converged end of the conical groove.

[0009] Optionally, the groove extends from the end surface of the tenon body to the outer side surface.

[0010] Optionally, two of the grooves are provided, and the two grooves separate the outer side surfaces where the grooves are located into three protruding structures.

[0021] The utility model provides a rectangular mortise and tenon wedge assembly, comprising a mortise body 1 and a mortise wedge 2, wherein the cross section of the mortise body 1 is rectangular, a mortise groove 11 is provided at at least one end of the mortise body 1, the mortise wedge 2 is adapted to the mortise groove 11, a retracted end of the mortise groove 11 is connected to an elastic groove 12, and grooves 13 are provided on the outer side surfaces of the mortise body 1 on both sides of the mortise groove 11.

[0022] Specifically, when the tenon body 1 is provided with a tenon groove 11 at only one end thereof, a single-end groove rectangular tenon-mortise wedge assembly is formed. When the tenon grooves 11 are provided at both ends of the tenon body 1 to form a two-end groove tenon assembly, it is used for connecting and fixing the main parts of solid wood furniture, and prevents the two main parts from changing angles and loosening after they are matched with each other. When the tenon assembly is used for connection and fixing, the tenon wedge 2 is wedged into the tenon groove 11 to expand the end of the tenon body 1. The groove structure on the outer side provides a substantial structure for the expanded end of the tenon body 1 to occupy the space at the bottom of the reserved hole of the main part. The tenon body 1 is provided with a structure with a rectangular cross section, which makes it easy to position during the installation process, and the connection structure will not loosen due to rotation after it is formed. The setting of the elastic groove 12 provides a buffer for the tenon groove 11 to expand and crack the end of the tenon body under the action of the tenon wedge 2.

[0023] As an optional embodiment, the tenon groove 11 is a tapered groove, the wide end of which is opened on the end surface of the tenon body 1, and the tapered groove extends toward the middle of the tenon body 1 and gradually converges. The tapered surface of the tapered groove provides a path for the tenon wedge 2 to wedge in.

[0024] As an optional embodiment, the elastic groove 12 is configured as an arc groove connected to the converged end of the tapered groove. The arc groove is configured at the converged end of the tapered groove, which can eliminate the stress concentration at the end of the mortise when the mortise wedge opens the mortise, so that the mortise body will not crack.

[0025] As an optional embodiment, the tenon wedge 2 is a tapered wedge. The tapered structure of the tapered wedge is adapted to the setting of the tapered groove.

[0026] As an optional implementation, the length of the tapered wedge is adapted to the tapered groove, the thickness of the large end of the tapered wedge is greater than the opening distance of the large end of the tapered groove, and the thickness of the small end of the tapered wedge is adapted to the opening distance of the closed end of the tapered groove. When the small end of the tapered wedge is inserted along the tapered surface of the tapered groove until the two tapered surfaces are tangent, the other end of the tenon body 1 is struck to make the rectangular surface of the large end of the tapered wedge bear force, and the tapered surface of the tapered wedge must move along the tapered surface of the tapered groove of the tenon. The structural setting of the tapered wedge makes the ends of the wedge body on both sides of the tapered groove expand outward when the tapered wedge is wedged into the tapered groove.

[0027] As an optional embodiment, the groove 13 extends from the end surface of the tenon body 1 to the outer side surface.

[0028] As an optional embodiment, the grooves 13 are provided in two, and the outer side surfaces of the two grooves 13 are separated into three protruding structures 14. The grooves 13 and the protruding structures 14 are staggered, providing a substantial body for the tapered groove to occupy the expansion space at the bottom of the reserved hole of the main part under the action of the tenon wedge 2.
