Description

Technical Field

[0001] The utility model relates to the technical field of wooden bed assembly, in particular to an anti-loosening type wooden bed mortise and tenon structure. Background Art

[0002] The mortise and tenon is a connection method that uses a combination of convex and concave parts on two wooden components. The protruding part is called the tenon or the tenon head, and the concave part is called the mortise or the mortise, or the mortise groove. The tenon and the mortise work together to connect. This is the main structural method for ancient Chinese architecture, furniture and other wooden appliances. The mortise and tenon structure is a combination of the tenon and the mortise, and is an ingenious combination of more and less, high and low, long and short between wooden pieces, which can effectively limit the twisting of wooden pieces in all directions.

[0003] Existing solid wood beds are mostly assembled by bolts, screw holes, slots, and blocks, which makes it inconvenient to disassemble during subsequent transportation or cleaning. When the wooden board is damaged, it is also inconvenient to disassemble and replace it. Utility Model Content

[0028] Please refer to the attached Figure 1-4 A mortise and tenon structure of an anti-loosening wooden bed body includes supporting legs 1, vertical beams 2 and cross beams 3, wherein the supporting legs 1 are provided with four groups, the vertical beams 2 are provided with two groups, the two groups of vertical beams 2 are respectively clamped between the paired supporting legs 1, and multiple groups of cross beams 3 are clamped with the vertical beams 2 along the length direction.

[0029] More specifically, a plurality of groups of mortises 4 are provided on the support leg 1 along the height direction of the side facing the vertical beam 2, and tenons 5 mortise-joined with the mortise 4 are provided on the two end walls of the vertical beam 2, wherein the mortise 4 is provided with an arc groove 8 inwardly along its circumference direction, and an arc flange 9 is provided at the end of the tenon 5 to cooperate with the arc groove 8; the locking after insertion is completed by the cooperation between the arc flange 9 and the arc groove 8, and the mortise 4 is teardrop-shaped, and the tip is set downward, the height of the tenon 5 is half of the mortise 4 and the shape is set to cooperate with the tip of the mortise 4. After the tenon 5 is inserted into the mortise 4, it moves downward and is locked with the arc groove 8 and the arc flange 9.

[0030] In order to ensure a stable connection, two groups of tenons 5 are provided along the height direction of the vertical beam 2. The spacing between the two tenons 5 is consistent with the spacing between the multiple groups of tenons 4. At the same time, in order to prevent the vertical beam 2 from moving upward, a positioning hole 10 is provided near the tip of the tenon 4, and the slots 6 on both sides of the vertical beam 2 are provided with pin holes 11 that penetrate the upper tenon 5. After the tenon and the tenon are fixed, the pin is inserted through the pin hole and then snapped into the positioning hole, so that the vertical beam is now displaced upward, thereby ensuring the stability of the bed after assembly.

[0031] Since the pin hole 11 is arranged in the slot 6, the pin can be further prevented from sliding after the crossbeam is assembled, thereby ensuring the stability of the structure during use.

[0032] In order to prevent the lateral movement of the vertical beams on both sides after the cross beam is assembled, a reducing opening is provided at the notch of the clamping slot 6, and a reducing section is provided on the clamping plate 7 to match the notch, so that the vertical beam 2 can be clamped in the horizontal movement direction. Finger grooves 12 are provided on either side of the cross beam 3, and the cross beam 3 can be easily removed through the finger grooves 12.
