[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0015] Example 1

[0016] See also Figure 1 and Figure 2 , which is the first embodiment of the utility model, and this embodiment provides a technical solution: a plate close splicing and base-free device, comprising a wall-mounted connector 1, a screw rod 2, a square end block 3, a customized keel 4, a fixing nut 1 6 and a fixing nut 2 7, the square end block 3 is welded and fixed to the right end of the screw rod 2, a rod hole corresponding to the screw rod 2 is penetrated through the surface of the wall-mounted connector 1 through the rod hole, the left end of the screw rod 2 penetrates the surface of the wall-mounted connector 1 through the rod hole and is fixedly connected to the wall-mounted connector 1 through two fixing nuts 2 7, expansion bolts 8 are provided on both sides of the wall-mounted connector 1, a T-slot 41 corresponding to the square end block 3 is provided on the left side of the customized keel 4, the square end block 3 slides into the T-slot 41, and a fixing nut 1 6 is sleeved on the right end surface of the screw rod 2, the fixing nut 1 6 is pressed and contacted with the customized keel 4, and the right end of the customized keel 4 is stuck in Between the two finished wood veneers 9, since both sides of the finished wood veneer 9 are provided with strip notches corresponding to the customized keels 4, the right end of the customized keel 4 can slide into the strip notch, thereby realizing the coordinated installation between the customized keel 4 and the finished wood veneer 9, and completing the close connection at the connecting gap of the two finished wood veneers 9. During the early installation, the wall-mounted connector 1 is first installed on the wall through the expansion bolt 8, and then the square end block 3 at the end of the screw 2 is slid into the T-slot 41, and the fixing nut 6 is tightened at the appropriate position to realize the fixed connection between the screw 2 and the customized keel 4. Finally, the finished wood veneer 9 can be assembled with the customized keel 4 through the strip notch on the side. The limit of the screw 2 can also be released by loosening the fixing nut 2 7, and then the screw 2 can be moved back and forth to change the position of the finished wood veneer 9, so as to realize the flexible adjustment of the thickness of the finished surface according to the space requirements.

[0017] The auxiliary limiting structure is also included, and the auxiliary limiting structure is arranged between the square end block 3 and the customized keel 4. The auxiliary limiting structure includes an inner groove 31 opened inside the square end block 3, and a spring 32 and a hemispherical telescopic block 33 are arranged in the inner groove 31. The inner wall of the T-shaped groove 41 is evenly provided with a plurality of positioning grooves 44 corresponding to the hemispherical telescopic block 33 along its height direction. The right end of the hemispherical telescopic block 33 pops out into one of the positioning grooves 44, so that after the square end block 3 is pushed into the T-shaped groove 41, the end of the hemispherical telescopic block 33 will be squeezed in first. The square end block 3 can be pushed into the inner groove 31 smoothly, and when the square end block 3 is pushed into a suitable installation position, the end of the hemispherical telescopic block 33 will pop out into the positioning groove 44 under the push of the spring 32, thereby limiting the square end block 3. At the same time, since there are multiple positioning grooves 44, the square end block 3 can be limited when it is pushed into multiple positions on the inner side of the T-slot 41, thereby playing an auxiliary limiting role for the screw rod 2 and the wall connector 1 when the fixing nut 6 is not tightened, making it convenient for the operator to perform subsequent tightening operations.

[0018] One end of the spring 32 is fixed to the inner wall of the inner groove 31 , and the other end of the spring 32 is fixedly connected to the hemispherical telescopic block 33 , so that the spring 32 can be stably installed.

[0019] A right hole communicating with the inner groove 31 is formed on the right side surface of the square end block 3, and the right hole is matched with the hemispherical telescopic block 33 to facilitate the smooth ejection of the right end of the hemispherical telescopic block 33.

[0020] Example 2

[0021] See also Figures 1 to 3 , which is the second embodiment of the utility model, is based on the previous embodiment, and the difference is that the positioning structure can be set to play a role of positioning reminder when the customized keel 4 and the finished wood veneer 9 are assembled together, thereby further improving the assembly convenience of the device.

[0022] Specifically, it also includes a positioning structure, which is arranged between the customized keel 4 and the finished wood veneer 9. The positioning structure includes a rubber seat 5 installed on the right side surface of the customized keel 4. The rubber seat 5 is located at the connecting gap between the two finished wood veneers 9, further improving the closeness of the connection between the two finished wood veneers 9. Both side surfaces of the rubber seat 5 are provided with integrated positioning protrusions 53, both of which are made of rubber material and will undergo elastic deformation when squeezed. The surface of the finished wood veneer 9 is provided with a positioning groove 91 corresponding to the positioning protrusion 53, and the positioning protrusion 53 is embedded in the positioning groove 91, so that when the customized keel 4 is assembled with the finished wood veneer 9, when the two ends of the customized keel 4 slide into the strip notches on the sides of the two finished wood veneers 9 respectively, the positioning protrusion 53 will also be squeezed into the positioning groove 91, thereby playing an auxiliary positioning role for the rubber seat 5 and the customized keel 4, and reminding the operator that the customized keel 4 and the screw 2 and other structures are in the installation position at this time.

[0023] Among them, an integrated plug-in block 51 is provided on the left surface of the rubber seat 5, and a plurality of integrated side clamping blocks 52 are provided on the surface of the plug-in block 51, both of which are made of rubber material and will undergo elastic deformation when squeezed.
