[0033] In some embodiments, when the first mounting member 2 is spliced in the first mounting groove 4, the bottom surface of the first mounting member 2 is supported on the upside of the bottom surface of the first mounting groove 4, the top surface of the first mounting member 2 is flush with the top end face 7 and is limited on the downside of the abutting face 8, so as to limit the first mounting member 2 between the bottom surface of the first mounting groove 4 and the abutting face 8, preventing the blocking structure 10 from moving along the length direction of the blocking body 1 relative to the first support frame 20 or the second support frame 30, and further improving the stability of the overall structure of the spliced wooden screen. In addition, the top surface of the first mounting member 2 is flush with the top end face 7, which can more accurately splice the first mounting member 2 in the first mounting groove 4, facilitating splicing.

[0034] In some embodiments, the two ends of the third support frame 40 are concavely provided with positioning grooves 402 matched with the upper ends of the first support frame 20 or the second support frame 30, respectively, the top surface of the positioning groove 402 forms the abutting surface 8, the tenon 62 extends downward from the top surface of the positioning groove 402, which reduces the setting width of the third support frame 40, reduces the damage of the tenon 62 caused by collision during transportation, and further reduces the volume of the third support frame 40, facilitating transportation.

[0036] As shown in Figure 2 In some embodiments, the first mounting member 2 is arranged in a strip structure along the length direction of the blocking body 1, and the first mounting groove 4 is arranged in a strip groove structure matched with the first mounting member 2, which facilitates the smooth pushing of the first mounting member 2 into the first mounting groove 4 along the length direction of the first mounting groove 4, improves the splicing efficiency, and the cooperation of the strip structure and the strip groove structure makes the connection between the first mounting member 2 and the first mounting groove 4 more closely and reliably, improving the stability of the splicing. In addition, the blocking structure 10, the first mounting member 2 and the second mounting member 3 are arranged in an integrated structure and are integrally machined, and the strip structure design also facilitates the rapid machining of the blocking structure 10, improving the machining efficiency.

[0037] As shown in Figure 3As shown, in some embodiments, the second mounting member 3 and the narrow neck portion 22 are formed by part of the structure of the barrier body 1, which simplifies the structure and facilitates the processing of the barrier structure 10. The limiting portion 21 includes a first limiting surface 211 arranged along the thickness direction of the barrier body 1, and a second limiting surface 212 and a third limiting surface 213 respectively connected between the two sides of the first limiting surface 211 and the two sides of the narrow neck portion 22. The vertical distance between the second limiting surface 212 and the plane a on which the barrier body 1 is gradually increased from the side close to the narrow neck portion 22 to the side close to the first limiting surface 211, and the vertical distance between the third limiting surface 213 and the plane a on which the barrier body 1 is gradually increased from the side close to the narrow neck portion 22 to the side close to the first limiting surface 211, so that the first mounting member 2 and the first mounting groove 4 can be better limited and fixed to prevent the barrier body 1 from shaking or shifting during use. The gradually widening structure design of the second limiting surface 212 and the third limiting surface 213 makes the barrier structure 10 move along the width direction of the barrier body 1 towards the outside of the narrow neck groove 42, and the second limiting surface 212 and the third limiting surface 213 cooperate with the limiting groove 41 more and more closely, thereby better preventing the barrier structure 10 from moving along the width direction of the barrier body 1 and being disconnected from the first support frame 20 or the second support frame 30, further improving the stability of the connection between the barrier structure 10 and the first support frame 20 and the second support frame 30. Of course, in other embodiments, only the second limiting surface 212 or only the third limiting surface 213 can be provided with the above-mentioned gradually widening structure, which can also make the limiting portion 21 cooperate with the limiting groove 41 more and more closely when the barrier structure 10 moves along the width direction of the barrier body 1 towards the outside of the narrow neck groove 42.
