[0045] In the prior art, the technical problems in the background art appear.

[0046] In order to solve the above technical problems, as shown in the background Figures 1 to 16 The embodiment of the present application discloses a clamping groove piece 1, which is characterized by comprising a clamping groove piece body, a front recess 11 is formed on the front side of the clamping groove piece body, a rear recess 12 is formed on the rear side of the clamping groove piece body, at least a part of the rear side groove bottom of the front recess 11 is communicated with at least a part of the front side groove bottom of the rear recess 12, an unlocking portion 13 is formed on the upper side inner wall of the front recess 11 and / or the upper side inner wall of the rear recess 12, the unlocking portion 13 comprises an unlocking surface 131 which gradually inclines backward from top to bottom, a flange portion 14 is formed on the left side inner wall and / or the right side inner wall and / or the lower side inner wall of the front recess 11; wherein the front recess 11 is used for matching a part of the front mold body of the mold for demolding in the front-rear direction (not shown in the figure), and the rear recess 12 is used for matching a part of the rear mold body of the mold for demolding in the front-rear direction (not shown in the figure).

[0047] Wherein, the card slot piece 1 of the embodiment of the present application is used in cooperation with the telescopic tenon 2, wherein the structure of the telescopic tenon 2 may be, for example, the telescopic tenon 2 in the “connecting assembly and connecting system” disclosed in Chinese patent application No. CN202211715955.6, which is omitted here. In use, the card slot piece 1 is installed on the first furniture plate, and the telescopic tenon 2 is installed on the second furniture plate, which can move in the up-down direction relative to the first furniture plate. Further, as shown in the figure, the front-rear direction of the card slot piece 1 is the left-right direction of the second furniture plate relative to the first furniture plate after the card slot piece 1 is installed on the first furniture plate, and the left-right direction of the card slot piece 1 is the front-rear direction of the second furniture plate relative to the first furniture plate after the card slot piece 1 is installed on the first furniture plate.

[0048] It can be understood that, due to the unlocking portion 13 inside the front groove 11 and / or the rear groove 12, and the flange portion 14 inside the front groove 11, so that the structural shape of the front groove 11 is different from that of the rear groove 12, the rear side of the front groove 11 is connected to the front side of the rear groove 12 to form a continuous channel, therefore the present application does not distinguish or limit the specific structure or shape of the front groove 11 and the rear groove 12, and is specifically adapted according to the design of the mold, that is, part of the front groove 11 can belong to part of the rear groove 12, and part of the rear groove 12 can belong to part of the front groove 11. For example, the projection area formed by the side edges of the flange portions 14 on the left and right sides of the card slot piece 1 is enclosed between the front side of the unlocking portion 13 to form the front groove 11, and the rear side of the flange portion 14 to the rear side of the card slot piece body to form the rear groove 12; for another example, the projection area formed by the side edges of the flange portions 14 on the left and right sides of the card slot piece 1 is enclosed between the front side of the unlocking portion 13 and the rear side of the card slot piece 1 to form the front groove 11, and the remaining part is the rear groove 12. Therefore, the structural shape of the front groove 11 and the structural shape of the rear groove 12 of the embodiment of the present application are specifically designed according to the front mold body and the rear mold body.

[0049] The structure of the card slot piece 1 can be a racetrack shape or a waist round shape or a circular shape, and correspondingly, the installation slot of the first furniture plate is also a racetrack shape or a waist round shape or a circular shape.

[0050] Based on the above technical solution, the front groove 11 and the rear groove 12 of the card slot piece 1 are distributed in the front-rear direction, the structural shape of the front groove 11 is set to cooperate with the structural shape of the corresponding part of the mold, and the structural shape of the rear groove 12 is set to cooperate with the structural shape of the corresponding part of the mold, so that the mold can be demolded in the front-rear direction to form the front groove 11 and the rear groove 12. The mold does not need to have a core and / or a mold body in other directions except the front-rear direction, so that a complete card slot piece 1 can be prepared, the flange portion 14 is formed by the continuous front groove 11 and the rear groove 12, and the demolding is simple and efficient.

[0051] In some embodiments, the card slot body is formed with a through hole 15, the two ends of the through hole 15 respectively penetrating the front side and the rear side of the card slot body, the through hole 15 is used for the fastener to pass through to fasten the card slot body on the first furniture plate. The fastener is, for example, a conventional screw or bolt or self-tapping screw, and the card slot 1 is fastened on the first furniture plate by the fastener, which improves the transverse tensile force (the tensile force of the first furniture plate and the second furniture plate in the left-right direction) of the first furniture plate and the second furniture plate, and improves the stability of the whole furniture cabinet. The number of through holes 15 can be one or more. Correspondingly, the mold also has front and / or rear core pulling members corresponding to the through holes 15, and the through holes 15 are formed when the mold is demolded in the front-rear direction.

[0052] In some embodiments, the card slot body is formed with a through hole 15, the two ends of the through hole 15 respectively penetrating the front side and the rear side of the card slot body, the through hole 15 is used for the fastener to pass through to fasten the card slot body on the first furniture plate. The fastener is, for example, a conventional screw or bolt or self-tapping screw, and the card slot 1 is fastened on the first furniture plate by the fastener, which improves the transverse tensile force (the tensile force of the first furniture plate and the second furniture plate in the left-right direction) of the first furniture plate and the second furniture plate, and improves the stability of the whole furniture cabinet. The number of through holes 15 can be one or more. Correspondingly, the mold also has front and / or rear core pulling members corresponding to the through holes 15, and the through holes 15 are formed when the mold is demolded in the front-rear direction.

[0053] In some embodiments, the flange part 14 of the left inner wall of the front groove 11 comprises a left inclined surface 141 gradually inclined to the right from top to bottom, and the flange part 14 of the right inner wall of the front groove 11 comprises a right inclined surface 142 gradually inclined to the left from top to bottom. The distance between the upper side of the left inclined surface 141 and the upper side of the right inclined surface 142 is greater than the width of the connecting part 21 of the telescopic tenon 2. When there is a position error in the mounting groove of the first furniture plate or the mounting hole of the second furniture plate, the connecting part 21 can also be smoothly inserted into the upper side of the front groove 11. When the second furniture plate is moved downward for assembly relative to the first furniture plate, the connecting part 21 also moves downward in the front groove 11. Due to the position error of the mounting groove of the first furniture plate or the mounting hole of the second furniture plate, the connecting part 21 abuts against the left inclined surface 141 or the right inclined surface 142. During the downward movement of the connecting part 21, the clamping groove piece 1 is driven to slide rightward or leftward in the mounting groove, thereby adjusting the mounting position of the clamping groove piece 1 on the first furniture plate, so that the connecting part 21 can smoothly move to the lower inner wall of the front groove 11, and then the second furniture plate is smoothly mounted to the inner side wall of the first furniture plate. In this way, the appropriate position of the clamping groove piece 1 on the first furniture plate is adjusted by the cooperation between the connecting part 21 and the left inclined surface 141 or the right inclined surface 142, which effectively ensures that the second furniture plate can be smoothly mounted to the first furniture plate when there is a left-right position error in the mounting groove of the clamping groove piece 1, avoids the trouble of re-drilling holes on the first furniture plate or the second furniture plate after disassembling the connecting assembly, and is convenient and efficient to install. The use of the connecting assembly of the present application can improve the hole tolerance rate on the first furniture plate or the second furniture plate, and ensure that the second furniture plate is smoothly mounted to the inner side wall of the first furniture plate. In addition, after the second furniture plate is mounted on the first furniture plate, the telescopic tenon 2 on the second furniture plate is limited in the front-rear direction by the clamping groove piece 1, which effectively prevents the telescopic tenon 2 from being pulled out of the clamping groove piece 1 in the front-rear direction, thereby preventing the second furniture plate from being pulled outwards under stress, and improving the safety in use.

[0054] In some embodiments, at least a portion of the left inner wall of the rear groove 12 is gradually inclined to the right from top to bottom, and at least a portion of the right inner wall of the rear groove 12 is gradually inclined to the left from top to bottom, so as to enable a part of the telescopic tenon 2 to be smoothly slid downward from top to bottom after being inserted into the front groove 11, and improve the sliding smoothness of the connecting part 21 of the telescopic tenon 2 in the front groove 11.

[0055] In some embodiments, the flange part 14 is formed with a clamping part 17 near the lower side wall of the front groove 11, which cooperates with the connecting part 21 of the telescopic tenon 2, so that when the second furniture plate is in a stationary state, the second furniture plate is stably mounted on the first furniture plate and is difficult to be separated from the first furniture plate when subjected to an external force, thereby improving the connection stability of the second furniture plate and the first furniture plate.
