DETAILED DESCRIPTION

[0025] The following is combined with Figure 1 To Attachment Figure 6 This application is described in further detail.

[0026] When the existing technology is used on soft or uneven ground such as mud, tidal flats, and sand, one or more supporting legs of the level instrument support frame will sink into the soil due to the unstable geological hardness of the ground, causing the level instrument support frame to shake or tip over due to uneven gravity distribution.

[0027] Therefore, in order to solve the problem that the existing leveling instrument support frame is not adaptable and stable enough on different terrains. Figure 1 and Figure 2The present invention provides a level support frame, including two parts, a basic structure and an adaptive structure. Among them, the basic structure includes a base 1 and a plurality of supporting legs 2. The base 1 is used to install the level. As the main part of the support frame, the base 1 has sufficient strength and stability to withstand the weight of the level and various forces that may be generated during use. A plurality of supporting legs 2 are circumferentially connected to the base 1. The supporting legs 2 are rotatably connected to the base 1 and rotate along the direction of gravity to achieve angle adjustment with the ground. In order to facilitate the display, three supporting legs 2 are used as a display in this embodiment, and more can be set in other embodiments. In this way, the three supporting legs 2 are deployed to provide support for the base 1. The design of the supporting legs 2 enables the entire support frame to evenly divide the gravity of the base 1 and the level, adjust the centers of the two, and keep the level in a horizontal state. At the same time, the stability and accuracy of the level during use are ensured. Among them, the adaptive structure includes a leg tube 3 corresponding to the number of supporting legs 2. The leg tube 3 is arranged at the end of the corresponding supporting leg 2 away from the base 1, and the leg tube 3 and the supporting leg 2 are on the same straight line. The foot tube 3 is provided with a floating palm component 4, a pointed foot component 5 and a linkage component 6.

[0028] Reference Figure 2 Further, the floating palm assembly 4 includes at least three bone rods 41. One end of the bone rod 41 is rotatably connected to the bottom edge of the foot tube 3, and the other end extends outward. That is, the end of the bone rod 41 rotates in a direction away from or close to the foot tube 3. When a number of bone rods 41 rotate in a direction away from the foot tube 3, the angle between two adjacent bone rods 41 is less than ninety degrees, preferably sixty degrees. When a number of bone rods 41 rotate in the direction of the foot tube 3, the number of bone rods 41 approach each other and are in a retracted state. The plane where the number of bone rods 41 is located always has an angle with the foot tube 3. When the bone rods 41 are arranged in the inner side of the area enclosed by the number of foot tubes 3, the angle is an acute angle.

[0029] Reference Figure 2 , further, a paddle 42 is arranged between the two bone rods 41. The paddle 42 is a fan-shaped structure as a whole, and the two sides of the paddle 42 are respectively connected to the corresponding bone rods 41. And the two ends of the paddle 42 are concave, so that the paddle 42 is more flat when folded. The paddle 42 is elastic, and the paddle 42 is bent in the direction away from the foot tube 3 during the folding process, forming a structure with a water drop-shaped cross section. The paddle 42 is preferably made of rubber film or polyester fiber. The paddle 42 is unfolded when the bone rods 41 are away from each other, and cooperates with the bone rods 41 to form a duck foot-like structure, thereby increasing the contact area with the soil and reducing the single foot pressure of the level support frame. Further, a plurality of floating palm assemblies 4 are arranged toward the axis of the base 1. The paddle 42 and the bone rods 41 are both in the space enclosed by the plurality of foot tubes 3, so that the duck foot structure composed of the paddle 42 and the bone rods 41 is more concentrated in the direction to increase buoyancy and reduce the degree of settlement.

[0030] Reference Figure 2 and Figure 3 Furthermore, the floating palm assembly 4 also includes a structure for controlling the movement of a plurality of bone rods 41. The floating palm assembly 4 also includes a slider 44 and a plurality of connecting rods 43. The slider 44 is axially slidably connected to the surface of the foot tube 3. The number of connecting rods 43 corresponds to the bone rod 41. One end of the connecting rod 43 is rotatably connected to the slider 44, and the other end is rotatably connected to the middle of the bone rod 41. When the slider 44 slides on the outer wall of the foot tube 3, the bone rod 41 and the paddle 42 are driven to expand or retract through the connecting rod 43. Such a design enables the floating palm assembly 4 to automatically adjust the contact area according to the ground conditions, thereby improving the stability and adaptability of the support frame.

[0031] Reference Figure 3 and Figure 4 Furthermore, the pointed foot assembly 5 includes a pointed block 51 and a control tube 52. A through groove 32 is axially provided at the bottom of the foot tube 3, and the through groove 32 runs through the bottom of the foot tube 3. One end of the control tube 52 is slidably connected to the through groove 32, and the other end is connected to the pointed block 51. The pointed block 51 can slide out of the through groove 32 to the outside. The pointed block 51 is a conical structure, which is used to be inserted into soil with suitable hardness to improve the stability of the support frame. The stability and load-bearing capacity of the supporting foot 2 are enhanced, so that the support frame can adapt to a variety of terrains, and the stability and accuracy of the level during use are improved. On hard ground, since the soil will not settle, it is only supported by the pointed block 51, and the floating palm assembly 4 is in a retracted state to avoid wear.

[0032] Reference Figure 3 and Figure 4, further, in order to make the adjustment (switching) process of the floating palm assembly 4 and the pointed foot assembly 5 more efficient. The present invention is also provided with a linkage assembly 6 for simultaneously controlling the slider 44 and the control cylinder 52, and driving the pointed block 51 to be retracted or extended out of the through slot 32 while controlling the paddle 42 to expand or contract. Specifically, the foot tube 3 is hollow inside to form a cavity 31, and there is a barrier between the cavity 31 and the through slot 32, and the cavity 31 and the through slot 32 are connected through a clearance hole 33. The linkage assembly 6 includes a bidirectional screw 61, a first drive block 62 and a second drive block 63. The bidirectional screw 61 is coaxially rotatably connected to the cavity 31 of the foot tube 3. The two ends of the bidirectional screw 61 respectively penetrate the first drive block 62 and the second drive block 63, and are threadedly connected to the two. A slide groove 34 is provided on the surface of the foot tube 3. The first drive block 62 is provided with a slide rod 621 that can pass through the slide groove 34 to connect the slider 44. In this way, when the first driving block 62 moves, the slider 44 will be driven to slide axially along the foot tube 3 through the sliding rod 621, and then the bone rod 41 and the paddle 42 of the floating palm assembly 4 will be driven to expand or retract through the connecting rod 43. The second driving block 63 is connected to the end of the control tube 52 through the round rod 631, and the round rod 631 passes through the clearance hole 33. When the bidirectional screw 61 rotates, the first driving block 62 and the second driving block 63 will move in opposite directions of the screw respectively, and the first driving block 62 drives the slider 44 to slide axially along the foot tube 3 through the sliding rod 621, and then the bone rod 41 and the paddle 42 of the floating palm assembly 4 will be driven to expand or retract through the connecting rod 43. The second driving block 63 is connected to the end of the control tube 52 through the round rod 631, driving the control tube 52 and the pointed block 51 to slide in the through groove 32. The sliding rod 621 and the sliding groove 34 cooperate to limit the rotation of the first driving block 62, and the clearance hole 33 and the round rod 631 cooperate to limit the rotation of the second driving block 63.

[0033] Reference Figure 5 Further, the linkage assembly 6 also includes a control rod 64. The control rod 64 is arranged perpendicular to the length direction of the bidirectional screw 61, and the control rod 64 passes through the outer wall of the foot tube 3 and is rotatably connected to the foot tube 3. The control rod 64 is provided with an active bevel gear 641. The end of the bidirectional screw 61 is provided with a driven bevel gear 611 that can mesh with the active bevel gear 641. Further, the control rod 64 passes through the foot tube 3 in a direction away from the axis of the base 1 and is provided with a knob 642. The knob 642 is used to facilitate the user to perform a rotation operation.

[0034] Furthermore, in order to limit the movement of the fins 42 after being stored, an elastic ring (not shown in the figure) is also sleeved on the leg tube 3, and the elastic ring is a rubber band. When the fins 42 are folded, the elastic ring will play a limiting role to prevent the fins 42 from shaking or falling off during the storage process. Such a design further improves the stability and durability of the floating palm assembly 4.

[0035] Reference Figure 1 and Figure 6Furthermore, in order to improve the applicability of the muscle-building support frame, the support foot 2 adopts a telescopic structure. Specifically, the support foot 2 includes two ring sleeves 23, two clamping rods 22 and a main rod 21. The foot tube 3 is arranged on the main rod 21. The ends of the two clamping rods 22 are connected as a whole through an elastic sheet, and the end of the clamping rod 22 is rotatably connected to the base 1. The main rod 21 is located between the clamping rods 22. The ring sleeve 23 surrounds the two clamping rods 22 circumferentially. A locking bolt 231 is passed through the ring sleeve 23. The locking bolt 231 is threadedly connected to the ring sleeve 23. The locking bolt 231 can move along the length direction of the vertical clamping rod 22 and then push one of the clamping rods 22 against the main rod 21. The ring sleeves 23 are distributed at both ends of the clamping rod 22. The locking bolts 231 on the two ring sleeves 23 are arranged in opposite positions. Thereby, the locking force is evenly distributed on the two clamping rods 22, so that the clamping of the main rod 21 is more stable.

[0036] Furthermore, an end block 35 is provided on the foot tube 3. The end block 35 facilitates the movement of the main rod 21 to adjust the distance between the main rod 21 and the clamping rod 22.

[0037] Furthermore, a groove 221 is provided on one side opposite to the clamping rod 22, and the groove 221 matches the shape of the main rod 21. The groove 221 is provided along the length direction of the clamping rod 22 and passes through the bottom of the clamping rod 22.

[0038] The implementation principle of a level instrument support frame in the embodiment of the present application is: The support foot 2 is connected to the base 1 by rotation so that it can adapt to different terrains and angle requirements. The floating palm assembly 4, the pointed foot assembly 5 and the linkage assembly 6 arranged on the foot tube 3 work together to achieve stable support of the support frame on different terrains. The design of the bone rod 41 and the paddle 42 of the floating palm assembly 4 enables the support frame to increase the contact area and improve stability by unfolding the paddle 42 on soft or muddy ground. The pointed foot assembly 5 can penetrate the soil or rock on the hard ground and provide a solid support point. The adaptability and stability of the level support frame on different terrains are improved, ensuring the accuracy and safety of the level during use.

[0039] 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.
