[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example: Figure 1-7 As shown, this utility model provides an easily adjustable building foundation pit support device, including a base plate 1. Two symmetrically distributed fixing blocks 1 are fixedly installed at the top edge of the base plate 1. A support plate 11 is rotatably installed on the top of the fixing blocks 1 via a pin. An adjustment mechanism 2 is provided at the top of the base plate 1. The adjustment mechanism 2 is used to adjust the angle of the support plate 11. A splicing mechanism 3 is provided at the top of the support plate 11.

[0023] The adjustment mechanism 2 includes two fixed plates 21, which are located on the left and right sides respectively. The right fixed plate 21 is higher than the left fixed plate 21. Two screw rods 22 are rotatably installed at the bottom of the fixed plate 21. The threads of the two screw rods 22 are in the same direction. A moving block 23 is threaded to the outer side of the screw rods 22. A support rod 24 is rotatably installed on the moving block 23 through a pin. A fixed block 2 is rotatably installed on the end of the support rod 24 away from the moving block 23 through a pin. The fixed block 2 is fixedly connected to the support plate 11.

[0024] The end of the screw 22 away from the support plate 11 is equipped with a drive mechanism 4, and the outer sides of the moving block 23 are equipped with limit mechanisms 5. By setting the adjustment mechanism 2, the movement of the moving block 23 drives the support rod 24 to move, pushing the support plate 11 to rotate around the pin on the fixed block 1 as the fulcrum until the angle of the support plate 11 is 90 degrees, and then stops rotating. The whole process does not require complicated steps, which can not only quickly complete the angle adjustment and support of the support plate 11, but also quickly fold and store it after the operation, effectively shortening the time spent on equipment adjustment and storage and improving work efficiency.

[0025] The splicing mechanism 3 includes a support plate 2 30. Two symmetrically distributed insert blocks 1 31 are fixedly installed at the bottom of the support plate 2 30. A slot 1 32, which mates with the insert blocks 1 31, is opened at the top of the support plate 2 30. Two symmetrically distributed fixing blocks 3 are fixedly installed on one side of the support plate 2 30. A support rod 2 33 is rotatably mounted on the side of the fixing blocks 3 away from the support plate 2 30 via a pin. A fixing block 4 is rotatably mounted on the side of the support rod 2 33 away from the support plate 2 30 via a pin. A support plate 34 is fixedly installed on the side of the fixing block 4 away from the support rod 2 33. A symmetrically distributed... The two insert blocks 35 of the support plate 21 are provided with slots 36 at the top of the fixing plate 21 for use with the insert blocks 35. By setting up the splicing mechanism 3, the insert block 31 on the support plate 30 is inserted into the slot 32 at the top of the support plate 11, and the insert block 35 on the support plate 34 is inserted into the slot 36 at the top of the right fixing plate 21. Then, the insert block 35 is fixed together with the fixing plate 21 by bolts to fix the support plate 30. This increases the height of the support plate 11, making it flexibly adaptable to the needs of foundation pit operations of different depths and enhancing the versatility of the equipment.

[0026] Two guide rods 25 are fixedly installed between the two fixed plates 21. The guide rods 25 are slidably connected to the moving block 23. By setting the guide rods 25, the moving block 23 is guided, making the moving block 23 more stable when it moves.

[0027] The drive mechanism 4 includes two discs 41, which are fixedly connected to screw 22. A connecting rod 42 is fixedly mounted on the side of the disc 41 away from screw 22 via a pin. A connecting plate 43 is rotatably mounted on the side of the connecting rod 42 away from the disc 41 via a pin. A connecting rod 44 is rotatably mounted on the side of the connecting plate 43 away from connecting rod 42 via a pin. A drive shaft 45 is fixedly mounted on the bottom of the connecting rod 44. A support block 46 is rotatably sleeved on the outside of the drive shaft 45. The support block 46 is fixedly connected to the base plate 1. By setting up the drive mechanism 4, the drive shaft 45 drives the connecting rod 44 to rotate. During the rotation of the connecting rod 44, the connecting plate 43 is moved. During the movement of the connecting plate 43, the connecting rod 42 is rotated. The rotation of the connecting rod 42 drives the discs 41 and screw 22 to rotate, thereby driving the moving block 23 to move. The drive shaft 45 rotates through the rotating wheel.

[0028] The limiting mechanism 5 includes two symmetrically distributed L-shaped blocks 51. A spring 52 is fixedly installed on the side of L-shaped block 51 closest to the moving block 23, and an L-shaped block 53 is fixedly installed on the side of spring 52 away from L-shaped block 51. A wedge 54 is fixedly installed on the side of L-shaped block 53 away from spring 52. A wedge 55, which cooperates with wedge 54, is fixedly installed on the side of the two moving blocks 23 closest to L-shaped block 53. By setting the limiting mechanism 5, wedge 55 moves with the moving blocks. 23 moves in the opposite direction to the drive mechanism 4. When the inclined surface of wedge 25 is in contact with the inclined surface of wedge 154, as wedge 25 continues to move, it pushes wedge 154 and L-shaped block 253 to move in the direction of L-shaped block 151. Spring 52 contracts. When the moving block 23 moves to the required position, spring 52 drives wedge 154 to rebound, so that the plane of wedge 154 is in contact with the plane of wedge 25, thereby limiting the moving block 23 and improving the stability of support rod 24.

[0029] The top of L-shaped block 2 53 is threaded with screw 2 57, and the top of L-shaped block 1 51 has a threaded hole that mates with screw 2 57. By setting screw 2 57, when it is necessary to store support plate 11, L-shaped block 2 53 is moved toward L-shaped block 1 51, so that wedge 1 54 moves away from wedge 2 55, spring 52 contracts, and then when screw 2 57 corresponds to the threaded hole on L-shaped block 1 51, screw 2 57 is rotated so that screw 2 57 is engaged in the threaded hole, fixing wedge 1 54 and preventing wedge 1 54 from being bounced back by spring 52, which would affect the movement of moving block 23 and the storage of support plate 11. Screw 2 57 is rotated by rotating wheel 2.

[0030] The spring 52 has a stabilizing rod 56 inside. One end of the stabilizing rod 56 is fixedly connected to the second L-shaped block 53, and the other end of the stabilizing rod 56 is slidably connected to the first L-shaped block 51. By setting the stabilizing rod 56, the spring 52 is more stable when it contracts. At the same time, it limits the wedge block 54 to prevent the wedge block 54 from rebounding too much and affecting the movement of the moving block 23. The stabilizing rod 56 is composed of a large-diameter round rod and a small-diameter round rod.

[0031] The spring 52 is provided with a telescopic rubber sleeve 58. One end of the rubber sleeve 58 is fixedly connected to L-shaped block 51, and the rubber sleeve 58 is fixedly connected to L-shaped block 53. By setting the rubber sleeve 58, the spring 52 is protected to prevent external forces from directly impacting the spring 52, causing the spring 52 to deform or break, thus affecting the use of the spring 52.

[0032] Working principle: In actual use, when it is necessary to adjust the angle of the support plate 11, the rotation of the rotating wheel 2 drives the drive shaft 45 and the connecting rod 44 to rotate. During the rotation of the connecting rod 44, the connecting plate 43 moves accordingly. During the movement of the connecting plate 43, the connecting rod 42 rotates. The rotation of the connecting rod 42 drives the two discs 41 and the screw 22 to rotate simultaneously. Under the guidance of the guide rod 25, the moving block 23 causes the screw 22 to rotate, which drives the moving block 23 to move in the opposite direction of the connecting rod 42, which drives the support rod 24 to move. This pushes the support plate 11 to rotate around the pin on the fixed block 1 as the fulcrum until the angle of the support plate 11 reaches 90 degrees, at which point the rotation stops.

[0033] When wedge 2 55 contacts and fits against the inclined surface of wedge 1 54, as wedge 2 55 continues to move, it will push wedge 1 54 and L-shaped block 2 53 to move towards L-shaped block 1 51. Spring 52 contracts. When moving block 23 moves to the target position, spring 52 causes wedge 1 54 to rebound, so that the plane of wedge 1 54 fits against the plane of wedge 2 55, thereby limiting the moving block 23 and improving the stability of support rod 1 24.

[0034] After the angle of the support plate 11 is adjusted, the support plate 11 is attached to the pit wall, and then the support device is nailed into the ground by rotating the screws to achieve fixation.

[0035] When encountering foundation pits of different depths, rotate support rod 2 33 to insert the insert block 31 of support plate 2 30 into slot 32 at the top of support plate 1 11, and then insert the insert block 2 35 on support plate 34 into slot 2 36 at the top of right fixing plate 21. Then, fix the insert block 2 35 to fixing plate 21 with bolts to complete the fixing of support plate 2 30. If it is necessary to stack it at a higher depth, it can be stacked on top.

[0036] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
