Detailed Implementation

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0022] The embodiments of this utility model will be described below based on its overall structure.

[0023] A solid wood cabinet with a mortise and tenon joint structure that can be easily disassembled and reassembled, such as... Figures 1 to 5 As shown, the cabinet includes a cabinet 100, which is composed of two sets of horizontal wooden boards 110 and vertical wooden boards 120 that are symmetrically spliced ​​together horizontally and vertically. An arc-shaped wooden strip 160 is added at the connection between two adjacent sets of horizontal wooden boards 110 and vertical wooden boards 120, and a partition 190 is inserted between the two sets of vertical wooden boards 120.

[0024] Locking strips 180 are provided on both sides of the horizontal wooden board 110 at the contact positions with the arc-shaped wooden strip 160. The side wall of the locking strip 180 is cut with four sets of cuts 181. The four sets of cuts 181 cut the locking strip 180 into three sets of locking blocks 182 and two sets of interlocking blocks 183. The upper and lower parts of the three sets of locking blocks 182 are reserved with irregular protrusions 184. The side of the arc-shaped wooden strip 160 is cut with a clearance groove 161 at the corresponding position of the locking strip 180. The clearance groove 161 and the three sets of irregular protrusions 184 are provided with widened grooves 162.

[0025] The inner walls of the two sets of vertical wooden boards 120 are provided with dovetail grooves 122, and one end of the dovetail groove 122 extends out of the rear surface of the vertical wooden board 120. The two ends of the partition 190 are provided with dovetail strips 191 that slide in the dovetail grooves 122.

[0026] The inner walls of the two sets of vertical wooden boards 120 are provided with vertical grooves 121 near the rear end. The inner walls of the two sets of horizontal wooden boards 110 are provided with horizontal grooves 170 at the position aligned with the vertical grooves 121. The inner walls of the four sets of arc-shaped wooden strips 160 are provided with arc-shaped grooves 163 at the corresponding positions of the horizontal grooves 170.

[0027] The upper and lower ends of the two sets of vertical wooden boards 120 are designed with the same structure as the horizontal wooden board 110.

[0028] When assembling the cabinet 100, first place the horizontal wooden board 110 horizontally on the workbench or the ground, and place the two sets of curved wooden strips 160 on both sides of the horizontal wooden board 110. Then, hold the curved wooden strips 160 close to the locking wooden strips 180 on the side of the horizontal wooden board 110, and make the curved wooden strips 160 and the horizontal wooden board 110 staggered. At this time, you can check whether the cut 181 is aligned with the widened groove 162. Then, make the three sets of locking wooden blocks 182 and the upper and lower parts... The irregular protrusion 184 enters the clearance groove 161 through the widened slot 162, and the remaining two side insert wooden blocks 183 enter the clearance groove 161 at the adjacent positions of the widened slot 162. Finally, an external force is applied forward to the arc-shaped wooden strip 160 until both ends of the arc-shaped wooden strip 160 are aligned with the horizontal wooden board 110, thus completing the locking purpose of the arc-shaped wooden strip 160 and the horizontal wooden board 110. The above operation can be repeated to complete the docking of the other side of the horizontal wooden board 110 with the arc-shaped wooden strip 160.

[0029] Next, the partition 190 is joined to the two sets of vertical wooden boards 120, allowing the dovetail strips 191 at both ends of the partition 190 to slide into the dovetail grooves 122. At this point, the partition 190 and the two sets of vertical wooden boards 120 form an H-shape. The two sets of vertical wooden boards 120 and the partition 190 are then moved above the previously joined horizontal wooden board 110. The joining method of the curved wooden strip 160 and the horizontal wooden board 110 can be repeated to complete the joining. Then, the back panel 150 is inserted from top to bottom into the vertical grooves 121 opened in the inner walls of the two sets of vertical wooden boards. Finally, the bottom of the back panel 150 will enter the horizontal groove 170. Finally, the other set of curved wooden strips 160 and the horizontal wooden board 110 are joined to the top of the two sets of vertical wooden boards 120. The drawer is then slid into the space below the partition 190, and the cabinet door 130 is installed on the front surface of the partition 190 using a screwdriver. This makes the assembly process of the cabinet 100 convenient.

[0030] Please refer to this carefully. Figure 3 and Figure 4 The length of the locking strip 180 is less than the length of the relief groove 161. The width of the inner wall of the relief groove 161 near the outer wall of the arc-shaped strip 160 is equal to the thickness of the locking strip 180. The width of the relief groove 161 near the depth is equal to the sum of the total thickness of the irregular protrusion 184 and the locking block 182.

[0031] Taking advantage of the fact that the size of the locking wooden strip 180 is smaller than that of the relief groove 161, when the arc-shaped wooden strip 160 is pushed, the locking wooden strip 180 can move a certain distance in the relief groove 161, causing the irregular protrusion 184 entering from the widened slot 162 to be misaligned with each other, thus achieving the locking purpose of the locking wooden strip 180 and the relief groove 161.

[0032] Please refer to this carefully. Figure 2 , Figure 3 , Figure 4 and Figure 5 The arc-shaped groove 163, the horizontal groove 170 and the vertical groove 121 form a frame groove on the inner wall of the cabinet 100, and a rear panel 150 that seals the rear surface of the cabinet 100 is inserted into the frame groove.

[0033] It serves to constrain the rear panel 150 located near the rear surface of the cabinet 100, making the splicing of the rear panel 150 simple and convenient.

[0034] Please refer to this carefully. Figure 5 Two sets of vertical wooden boards 120 are fixed with a constraint rail 123 on the side near the drawer 140, and the outer walls of both sides of the drawer 140 are provided with constraint grooves 141 that slide on the outer wall of the constraint rail 123.

[0035] The drawer 140 moves smoothly in and out of the cabinet 100 by using the constraint rail 123 and the constraint groove 141.

[0036] The front surface of the partition 190 is hinged to have a cabinet door 130 installed. Below the partition 190, inside the cabinet body 100, a drawer 140 is slidably installed. Both the cabinet door 130 and the drawer 140 have spindle-shaped handles on their front surfaces.

[0037] The cabinet door 130 and drawers can be opened via a shuttle-shaped handle, making it convenient for users to retrieve and place items inside the cabinet 100.

[0038] When assembling the cabinet 100, first place the horizontal wooden board 110 horizontally on the workbench or ground, and place the two sets of curved wooden strips 160 on both sides of the horizontal wooden board 110. Then, hold the curved wooden strips 160 close to the locking wooden strips 180 on the side of the horizontal wooden board 110, and make sure that the curved wooden strips 160 and the horizontal wooden board 110 are in a staggered state. At this time, you can check whether the cut 181 is aligned with the widened groove 162. Then, make sure that the three sets of locking wooden blocks 182 and the upper and lower parts are aligned. The irregular protrusion 184 of the part enters the relief groove 161 through the widened groove 162, and the remaining two side insert wooden blocks 183 enter the relief groove 161 at the adjacent positions of the widened groove 162. Finally, an external force is applied forward to the arc-shaped wooden strip 160 until the two ends of the arc-shaped wooden strip 160 are aligned with the horizontal wooden board 110, thus completing the locking purpose of the arc-shaped wooden strip 160 and the horizontal wooden board 110. The above operation can be repeated to complete the docking of the other side of the horizontal wooden board 110 with the arc-shaped wooden strip 160.

[0039] Next, the partition 190 is joined to the two sets of vertical wooden boards 120, allowing the dovetail strips 191 at both ends of the partition 190 to slide into the dovetail grooves 122. At this point, the partition 190 and the two sets of vertical wooden boards 120 form an H-shape. The two sets of vertical wooden boards 120 and the partition 190 are then moved above the previously joined horizontal wooden board 110. The joining method of the curved wooden strip 160 and the horizontal wooden board 110 can be repeated to complete the joining. Then, the back panel 150 is inserted from top to bottom into the vertical grooves 121 opened in the inner walls of the two sets of vertical wooden boards. Finally, the bottom of the back panel 150 will enter the horizontal groove 170. Finally, the other set of curved wooden strips 160 and the horizontal wooden board 110 are joined to the top of the two sets of vertical wooden boards 120. The drawer is then slid into the space below the partition 190, and the cabinet door 130 is installed on the front surface of the partition 190 using a screwdriver. This makes the assembly process of the cabinet 100 convenient.
