Description

Technical Field

[0001] This utility model relates to the field of furniture and flooring technology, and in particular to a self-locking flooring tenon and mortise splicing structure. Background Technology

[0002] Flooring is a building material or paving system used to cover the ground of a building, provide a walkable surface, and combine functionality and decoration. It is the top layer of flooring on the interior or exterior of a building, and comes into direct contact with the human body. It must meet physical properties such as load-bearing capacity, wear resistance, slip resistance, and sound insulation, as well as design requirements such as aesthetics and environmental protection.

[0003] A search revealed that Chinese patent CN217812113U discloses a mortise and tenon joint structure for Balau solid wood flooring. In this structure, the mortise and tenon joint uses a groove on the side, meaning the Balau solid wood flooring is installed from the side during the joint. However, when installing the Balau solid wood flooring to a wall, it cannot be moved to the side, causing interference during installation. Therefore, this existing mortise and tenon joint structure interferes with the installation of Balau solid wood flooring. The movable groove has a V-shaped pin that is movably connected inside. When installing Balau solid wood flooring, one end of the V-shaped pin is inserted into the interior of one side of the Balau solid wood flooring, while the other end of the V-shaped pin is tilted upwards. Another Balau solid wood flooring can be fitted onto the outside of the V-shaped pin. This increases the stability and convenience of installing two sets of Balau solid wood flooring when splicing them together, and avoids the problem of one V-shaped pin interfering with the installation of another V-shaped pin.

[0004] While the aforementioned floorboards can be stably joined using mortise and tenon joints, gaps will appear between the joints. Furthermore, the self-locking property of the mortise and tenon joints is poor. Over time, the tenons of the mortise and tenon jointed floorboards may loosen through the gaps between the tenons and the mortises, causing them to slide out of the mortise and tenon joints and reducing the stability and tightness of the mortise and tenon joints.

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a self-locking floor tenon and mortise splicing structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a self-locking floor tenon and mortise splicing structure, comprising a floor body, wherein a splicing component is provided on one side of the floor body;

[0007] The splicing assembly includes a first mortise, which is formed on one side of the floor panel. A tenon is fixedly connected to the other side of the floor panel. Two tenons are fixedly connected to one side of the floor panel, and two second mortises are formed on the other side of the floor panel.

[0010] As a further description of the above technical solution:

[0011] One end of the first spring is fixedly connected to a circular plate, and one side of the circular plate is fixedly connected to a cylinder. A short shell is slidably connected inside the second mounting groove, and a long shell is slidably connected inside the first mounting groove.

[0012] As a further description of the above technical solution:

[0013] Two of the cylinders are fixedly connected to the inner wall of the short shell, and a plurality of the cylinders are fixedly connected to the inner wall of the long shell.

[0014] As a further description of the above technical solution:

[0015] The upper surface of the floor body is provided with a limiting component, the limiting component including a receiving groove, the receiving groove being formed on the upper surface of the floor body.

[0016] As a further description of the above technical solution:

[0017] The lower surface of the receiving groove is provided with a cross groove, the inside of the tenon is provided with a through groove, the inside of the receiving groove is provided with a concave block, the lower surface of the concave block is fixedly connected with a cross block, and the middle of the concave block is fixedly connected with a pull rod.

[0018] As a further description of the above technical solution:

[0019] Both sides of the receiving groove are provided with recessed holes. A second spring is fixedly connected inside the recessed hole. A push block is fixedly connected to one end of the second spring. A limit ring is fixedly connected to the inner wall of the recessed hole. The push block is slidably connected inside the recessed hole.

[0020] This utility model has the following beneficial effects:

[0021] 1. This utility model, through the design of the splicing components, enhances the tightness of the splicing between the first mortise and tenon by utilizing the interlocking of the fastening groove and the fastening protrusion during the mortise and tenon splicing of the floor. The rounded corner of the protrusion facilitates its insertion into the rounded groove at the second mortise, thereby increasing the friction between the tenon and the second mortise. At the same time, the pushing action of the corresponding long shell on the inner wall of the first mortise and the pushing action of the short shell on the inner wall of the second mortise further enhances the tightness of the splicing between the tenon and the tenon, thus strengthening the self-locking function on the basis of the self-locking property of the mortise and tenon splicing itself.

[0022] 2. This utility model, through the setting of the limiting component, utilizes the interlocking of the cross block, cross groove and through groove to further lock the two floorboards after longitudinal splicing. Under the limiting effect of the cross block, it helps to reduce the phenomenon of separation between the longitudinal floorboards due to the small contact surface. Furthermore, under the action of the second spring pushing the push block and the push block exerting a pushing force on the concave block, the tightness of the concave block placed inside the receiving groove is improved.

[0036] As attached Figure 3 As shown, a first mounting groove 10 is provided on one side of the tenon 3 for mounting the first spring 13.

[0037] As attached Figure 4As shown, the tenon 4 has a second mounting groove 11 on both sides. Multiple protective shells 12 and multiple first springs 13 are fixedly connected inside the first mounting groove 10 and the second mounting groove 11. The protective shell 12 is set outside the first spring 13 and plays a role in preventing deformation of the first spring 13. A circular plate 14 is fixedly connected to one end of the first spring 13. A cylinder 15 is fixedly connected to one side of the circular plate 14 to facilitate the transmission of elastic force to the inner walls of the long shell 17 and the short shell 16. The short shell 16 is slidably connected inside the second mounting groove 11, and two cylinders 15 are fixedly connected to the inner wall of the short shell 16.

[0038] As attached Figure 5 As shown, a long shell 17 is slidably connected inside the first mounting groove 10, wherein a plurality of cylinders 15 are fixedly connected to the inner wall of the long shell 17, so that the elastic force of the first spring 13 can be used to press against the inner wall of the first mortise 2.

[0039] As attached Figure 6 As shown, a limiting component is provided on the upper surface of the floor body 1. The limiting component includes a receiving groove 18, which is opened on the upper surface of the floor body 1. A cross groove 19 is opened on the lower surface of the receiving groove 18.
