Description

Technical Field

[0001] This utility model belongs to the technical field of surveying instrument brackets, specifically relating to a steel structure surveying instrument bracket with high stability. Background Technology

[0002] A surveying instrument stand is a specialized device used to fix, support, and adjust surveying instruments. It aims to improve measurement accuracy, operational efficiency, and equipment stability, adapting to different scenario requirements. Through support legs (such as a spherical support ball design), it enables rapid leveling, ensuring the surveying instrument maintains a horizontal reference point in complex terrain.

[0003] A utility model patent with patent authorization announcement number CN207073690U discloses a steel structure surveying instrument bracket. The tripod includes telescopic rods that are hinged to three equal division points in the circumferential direction of the mounting base to adjust the height of the surveying instrument. A hinged connecting rod is provided between adjacent telescopic rods to limit the relative sliding of the telescopic rods. A fixing device is provided on the hinged connecting rod to fix the hinged connecting rod by means of threaded engagement, so as to achieve the purpose of keeping the surveying instrument bracket relatively fixed when subjected to external force.

[0004] However, existing surveying instrument supports also have certain drawbacks. Although existing surveying instrument supports mostly use components such as elastic damping parts to complete the deflection adjustment of the support legs, the stability of the support legs is easily weakened due to the influence of external factors such as vibration. Summary of the Invention

[0005] The purpose of this utility model is to provide a steel structure surveying instrument support with high stability, which solves the problem that existing surveying instrument supports, although mostly using elastic damping components to adjust the deflection of the legs, are prone to weak leg stability due to external factors such as vibration.

[0006] To achieve the above objectives, this utility model provides a highly stable steel structure surveying instrument bracket, including a mounting base. A support cylinder is fixedly connected to the lower center of the mounting base. A threaded cylinder is threadedly connected to the inner wall of the support cylinder. A support shaft is fixedly sleeved on the inner wall of the threaded cylinder. The support shaft contacts the mounting base. A handle is fixedly connected to the side of the support shaft. A pointed cone is fixedly connected to the lower end of the support shaft. A friction ring is fixedly connected to the surface of the pointed cone. A mounting ear is fixedly connected to the surface of the mounting base. A rotating shaft is rotatably connected to the inner wall of the mounting ear. A support foot is fixedly sleeved on the outer side of the rotating shaft. A stabilizing mechanism is provided on both the mounting base and the rotating shaft.

[0007] The principle of this utility model is as follows: by pulling the handle upward, the insertion rod slides along the inner wall of the horizontal part of the support frame, causing the spring to deform and eventually disengage the insertion rod from the insertion hole. Then, the support foot is pushed to rotate, and the position of the support foot is adjusted adaptively. When the support foot rotates, it can drive the rotating shaft to rotate, which in turn drives the rotating disk to rotate. When the handle is released, the spring can be restored to its original deformation, so as to pull the insertion rod to insert into the insertion hole and limit the insertion of the rotating disk, so that the support foot is in a stable adjustment state. By pushing the grip rod to drive the support shaft to rotate in the opposite direction, the threaded connection allows the support shaft to drive the threaded cylinder to rotate. The threaded connection allows the threaded cylinder to drive the support shaft to rotate downwards, thus causing the cone to sink into the ground. Under the action of the friction ring, the resistance and friction of the cone can be improved, thereby ensuring the good stability of the surveying instrument bracket.

[0008] The beneficial effects of this utility model are as follows: This solution drives the support shaft to rotate in the opposite direction by pushing the gripping rod. Under the threaded connection, the threaded cylinder can drive the support shaft to rotate downward, so that the pointed cone is embedded in the ground. Under the action of the friction ring, the resistance and friction of the pointed cone can be improved, thereby ensuring the good stability of the surveying instrument bracket. By pushing the rotating disk to rotate, the support legs can be deflected. The deflection angle of the support legs can be adjusted to facilitate the insertion and fixing of the surveying instrument bracket. Under the action of the insertion hole, insertion rod, spring and other structures, the rotating disk can be inserted, so that the support legs are stable after adjustment, thereby ensuring the insertion stability of the surveying instrument bracket.

[0009] Furthermore, there are two grips, which are symmetrically distributed on the support shaft. The grips facilitate the rotation of the support shaft.

[0010] Furthermore, multiple friction rings are provided, and the multiple friction rings are evenly distributed on the pointed cone. By providing friction rings, the friction effect on the surface of the pointed cone can be improved.

[0011] Furthermore, the mounting ears are provided in three places, and the three mounting ears are arranged in a circular array on the mounting base. The mounting ears can be used to install and use the support legs.

[0012] Furthermore, the stabilizing mechanism includes a rotating disk, which is fixedly sleeved on the outer side of the rotating shaft. The rotating disk is rotatably connected to the mounting ear. An insertion hole is provided on the surface of the rotating disk. A support frame is fixedly connected to the upper end of the mounting base. An insertion rod is slidably connected to the horizontal part of the support frame. The insertion rod is slidably connected to the insertion hole. A handle is fixedly connected to the upper end of the insertion rod. A spring is provided on the outer side of the insertion rod. Through the action of the insertion hole, insertion rod, and other structures, the rotating disk can be inserted, thereby stabilizing and limiting the use of the support leg.

[0013] Furthermore, the surface of the handle is provided with multiple friction grooves, which are evenly distributed on the handle. The contact effect of the handle surface can be improved by setting the friction grooves.

[0014] Furthermore, one end of the spring is fixedly connected to the handle, and the other end of the spring is welded to the horizontal part of the support frame. The handle can be connected and used through the setting of the spring. Attached Figure Description

Detailed Implementation

[0017] The implementation examples are basically as follows Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, this embodiment provides a highly stable steel structure surveying instrument bracket, including a mounting base 1. A support cylinder 2 is fixedly connected to the lower middle part of the mounting base 1. A threaded cylinder 3 is threadedly connected to the inner wall of the support cylinder 2. A support shaft 4 is fixedly sleeved on the inner wall of the threaded cylinder 3. The support shaft 4 is in contact with the mounting base 1. A handle 5 is fixedly connected to the side of the support shaft 4. A pointed cone 6 is fixedly connected to the lower end of the support shaft 4. A friction ring 7 is fixedly connected to the surface of the pointed cone 6. A mounting ear 8 is fixedly connected to the surface of the mounting base 1. A rotating shaft 9 is rotatably connected to the inner wall of the mounting ear 8. A support leg 10 is fixedly sleeved on the outer side of the rotating shaft 9.

[0018] like Figure 1 , Figure 2 , Figure 3As shown, there are two grips 5, which are symmetrically distributed on the support shaft 4. The grips 5 facilitate the rotation of the support shaft 4. There are multiple friction rings 7, which are evenly distributed on the cone 6. The friction rings 7 improve the friction effect on the surface of the cone 6. There are three mounting ears 8, which are arranged in a ring array on the mounting base 1. The mounting ears 8 allow the support leg 10 to be installed and used.

[0019] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a stabilizing mechanism 11 is provided on both the mounting base 1 and the rotating shaft 9. The stabilizing mechanism 11 includes a rotating disk 111. The rotating disk 111 is fixedly sleeved on the outer side of the rotating shaft 9. The rotating disk 111 is rotatably connected to the mounting ear 8. An insertion hole 112 is provided on the surface of the rotating disk 111. A support frame 113 is fixedly connected to the upper end of the mounting base 1. An insertion rod 114 is slidably connected to the horizontal part of the support frame 113. The insertion rod 114 is slidably connected to the insertion hole 112. A handle 115 is fixedly connected to the upper end of the insertion rod 114. A spring 116 is provided on the outer side of the insertion rod 114. Through the action of the insertion hole 112, the insertion rod 114 and other structures, the rotating disk 111 can be inserted, thereby stabilizing and limiting the use of the support leg 10.

[0020] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the surface of the handle 115 is provided with multiple friction grooves, which are evenly distributed on the handle 115. The friction grooves can improve the contact effect of the surface of the handle 115. One end of the spring 116 is fixedly connected to the handle 115, and the other end of the spring 116 is welded to the horizontal part of the support frame 113. The handle 115 can be connected and used through the spring 116.

[0021] The specific implementation process of this utility model is as follows: By pulling the handle 115 upward, the insertion rod 114 is driven to slide along the inner wall of the horizontal part of the support frame 113, causing the spring 116 to deform, and finally causing the insertion rod 114 to disengage from the insertion hole 112. Then, the support leg 10 is pushed to rotate, and the position of the support leg 10 is adjusted adaptively. When the support leg 10 rotates, it can drive the rotating shaft 9 to rotate, and then drive the rotating disk 111 to rotate. When the handle 115 is released, the spring 116 can be restored to its deformation, so as to pull the insertion rod 114 to insert into the insertion hole 112, and limit the insertion of the rotating disk 111, so that the support leg 10 is in a stable adjustment. By pushing the grip 5 to drive the support shaft 4 to rotate in the opposite direction, the support shaft 4 can drive the threaded cylinder 3 to rotate under the threaded connection. Under the threaded connection, the threaded cylinder 3 can drive the support shaft 4 to rotate downward, thereby causing the cone 6 to sink into the ground. Under the action of the friction ring 7, the resistance and friction of the cone 6 can be improved, thereby ensuring the good stability of the surveying instrument bracket.

[0022] This design uses the push handle 5 to drive the support shaft 4 to rotate in the opposite direction. With the threaded connection, the threaded cylinder 3 can drive the support shaft 4 to rotate downwards, causing the cone 6 to sink into the ground. Under the action of the friction ring 7, the resistance and friction of the cone 6 can be improved, thereby ensuring the good stability of the surveying instrument bracket. By pushing the rotating disk 11 to rotate, the support leg 10 can be deflected. The deflection angle of the support leg 10 can be adjusted to facilitate the insertion and fixing of the surveying instrument bracket. Under the action of the insertion hole 112, insertion rod 114, spring 116 and other structures, the rotating disk 111 can be inserted, so that the support leg 10 is stable after adjustment, thus ensuring the insertion stability of the surveying instrument bracket.
