DETAILED DESCRIPTION

[0023] The following is combined with Figure 1-5 This application is described in further detail.

[0024] The present application discloses a cross brace suitable for trench excavation support. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, a cross brace suitable for trench excavation support includes a first support plate 1, one side of the first support plate 1 is fixedly connected to one end of a support sleeve 2, one side of the middle outer surface of the support sleeve 2 is fixedly connected to the bottom of a protective shell 6, the top of the inner wall of the protective shell 6 is fixedly connected to one end of a limit rod 13, and the other end of the limit rod 13 is fixedly connected to one side of the middle outer surface of the support sleeve 2. The top cross-section of the limit rod 13 is a quadrilateral setting. The quadrilateral cross-section setting of the limit rod 13 can fix the angle of the limit frame 12 when it moves, thereby improving the stability of the connecting block 10 when it moves.

[0025] See also Figure 5 One end of the inner wall of the protective shell 6 is fixedly connected to one end of the telescopic outer tube 7, one end of the inner wall of the telescopic outer tube 7 is fixedly connected to one end of the spring 16, and the other end of the spring 16 is fixedly connected to one end of the telescopic inner rod 8. The spring 16 is set so that the spring 16 can be stretched when the telescopic inner rod 8 is extended from the telescopic outer tube 7, so that the spring 16 applies a pulling force to the telescopic inner rod 8, and then when the limit block 11 moves again to the upper side of the groove on one side of the outer surface of the middle part of the supporting strut 3, the spring 16 can pull the telescopic inner rod 8 to reset, so that the limit block 11 is reinserted into the supporting strut 3. In the groove on one side of the middle outer surface of the protective support rod 3, the inner wall of the other end of the telescopic outer tube 7 is sleeved with the outer surface of one end of the telescopic inner rod 8, and the other end of the telescopic inner rod 8 is rotatably connected to the inner wall of one end of the connecting rod 9 through a U-shaped frame, and the inner wall of the other end of the connecting rod 9 is rotatably connected to one side of the connecting block 10 through the U-shaped frame, one side of the connecting block 10 is fixedly connected to one end of the limit frame 12, and the middle inner wall of the limit frame 12 is slidably connected to the middle outer surface of the limit rod 13. The stability of the connecting block 10 during movement can be improved by sliding the middle inner wall of the limit frame 12 on the middle outer surface of the limit rod 13.

[0026] See also Figure 4One end of the connecting block 10 is fixedly connected to one end of the limit block 11, and the two sides of one end of the limit block 11 are inclined, and the inclined surfaces on both sides of one end of the limit block 11 are symmetrically arranged, and the inclined surfaces on both sides of one end of the limit block 11 are slidably connected to the two sides of the inner wall of the limit groove on one side of the middle outer surface of the supporting strut 3. Through the inclined setting of both sides of one end of the limit block 11, the supporting strut 3 can push the rod limit block 11 to move when it rotates, and then push the limit block 11 out of the groove on one side of the middle outer surface of the supporting strut 3, so that the limit block 11 releases the restriction on the supporting strut 3, so that the supporting strut 3 can be smoothly extended from the supporting sleeve 2.

[0027] See also Figure 2 The inner wall of one end of the supporting sleeve 2 is slidably connected with the outer surface of one end of the supporting strut 3, and a limiting groove is opened on one side of the middle outer surface of the supporting strut 3. The inner wall of one end of the supporting strut 3 is threadedly connected with the outer surface of one end of the first threaded rod 4, and the other end of the first threaded rod 4 is rotatably connected with one side of the second supporting plate 5. A nut is fixedly provided on the middle outer surface of the first threaded rod 4. By rotating the nut fixedly provided on the middle outer surface of the first threaded rod 4, the first threaded rod 4 can be driven to rotate, so that the first threaded rod 4 can extend from the inner wall of one end of the supporting strut 3, driving the second supporting plate 5 to move to one side of the inner wall of the groove, and fine-tuning the cross brace after the length is greatly adjusted.

[0028] See also Figure 3 One side of the middle outer surface of the supporting sleeve 2 is rotatably connected to one end of the second threaded rod 14 through a connecting plate, the middle outer surface of the second threaded rod 14 is threadedly connected to the inner wall of one end of the limiting plate 15, and the inner wall of the other end of the limiting plate 15 is slidably connected to the middle outer surface of the limiting rod 13. The limiting plate 15 can be driven to move by rotating the second threaded rod 14, and the height of the limiting plate 15 can be adjusted so that the limiting plate 15 can limit the position of the limiting frame 12, and then limit the position of the connecting block 10, so that the limiting block 11 cannot be moved out of the limiting groove of the supporting strut 3, and the position between the supporting strut 3 and the supporting sleeve 2 is fixed, so as to improve the stability after the length of the cross brace is adjusted, and the outer surface of the other end of the second threaded rod 14 is rotatably connected to the inner wall at the top of the protective shell 6.

[0029] The implementation principle of one embodiment of the present application is as follows: when it is necessary to support the inner wall of the groove, the stored cross brace is taken out, and the supporting strut rod 3 is rotated to make the supporting strut rod 3 rotate in the supporting sleeve 2. When the supporting strut rod 3 rotates, the inner wall of the limit groove will push the inclined outer surface of the limit block 11, so that the limit block 11 is gradually moved out of the limit groove of the supporting strut rod 3. When the limit block 11 moves upward, it will drive the connecting block 10 to move upward, so that the connecting block 10 drives the connecting rod 9 to swing. When the connecting rod 9 is moved, the connecting rod 9 will drive the telescopic inner rod 8 to extend from the telescopic outer tube 7, stretching the spring 16. At the same time, when the connecting block 10 moves, it will drive the inner wall of the middle part of the limit frame 12 to slide on the outer surface of the middle part of the limit rod 13 until the limit block 11 is completely moved out of the limit groove of the support strut 3, releasing the restriction on the support strut 3, pulling the support strut 3 to extend from the support sleeve 2, so that the length of the support strut 3 and the support sleeve 2 is greatly close to the horizontal bracing length required by the inner wall of the groove, and rotating The support strut 3 is moved to the bottom of the limit block 11 until the limit slot of the support strut 3 is moved again. The spring 16 will pull the telescopic inner rod 8 to retract the telescopic inner rod 8 into the telescopic outer tube 7. At the same time, the connecting rod 9 will drive the connecting block 10 to move downward, drive the limit block 11 to be reinserted into the limit slot of the support strut 3, rotate the second threaded rod 14, drive the limit plate 15 to move downward, make the bottom of the limit plate 15 close to the top of the limit frame 12, and make the limit plate 15 pass through the limit frame 12 fixes the height of the connecting block 10, and then fixes the position of the limit block 11 to prevent the limit block 11 from moving out of the limit groove of the supporting strut 3 again, and rotates the nut fixed on the outer surface of the middle part of the first threaded rod 4 to drive the first threaded rod 4 to rotate, so that the first threaded rod 4 extends from the inner wall of one end of the supporting strut 3, and drives the second supporting plate 5 to move to one side of the inner wall of the groove, so that the second supporting plate 5 cooperates with the first supporting plate 1 to support both sides of the inner wall of the groove.

[0030] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
