Description

Technical Field

[0001] The utility model relates to the technical field of prism placement racks, in particular to a prism rod placement rack. Background Art

[0002] During the construction process, measurement plays a pioneering and guiding role, just like the eyes of the project. The quality of the measurement results directly affects the quality of the entire project. Therefore, prism measurement is needed during the construction process. Construction workers place the prism rod at the designated position for measurement. Prisms of different specifications are required in different measurement situations. Therefore, the prism needs to be removed from the prism rod and replaced. However, the existing prism rod placement frame usually uses bolts to fix the prism body. Although this fixing method is stable, it is complicated to replace, cannot be replaced quickly, and is not very practical. Utility Model Content

[0003] In view of this, the utility model provides a prism rod placement rack, which can quickly replace the prism body, improve the replacement efficiency, and is more practical.

[0004] In order to solve the above technical problems, the utility model provides a prism rod placement rack, including a support table, a bracket is arranged at the center of the bottom surface of the support table, a driving frame is arranged on the upper surface of the support table, a rotating disk is connected to the center of the upper surface of the driving frame, an installation frame is arranged on the upper surface of the rotating disk, an inserting limit frame is arranged in the installation frame, two movable blocks are slidably arranged on both sides of the limit frame, and a spring is arranged between the movable blocks, through holes are opened on both sides of the inner wall of the limit frame, positioning blocks are arranged on both sides of the surface of the movable block, the positioning blocks pass through the through holes of the limit frame, and the cross section of the positioning blocks is adapted to the cross section of the through holes of the limit frame, positioning holes are opened on both sides of the installation frame, and the positioning blocks are inserted in the positioning holes of the installation frame, a sliding groove is opened on the surface of the limit frame, a connecting block is arranged on the surface of the movable block and on one side facing the sliding groove of the limit frame, the connecting block is slidably arranged in the sliding groove of the limit frame, and a handle is arranged at the end of the connecting block The hand, the fixing plate at the upper end of the limit frame, and the upper surface of the fixing plate are provided with a prism body. When the staff needs to install the prism body, they first pull the two handles with their fingers to make the two handles close to each other, and at the same time, the handles drive the connecting block and the movable block to move synchronously. When the movable blocks are close to each other, the spring is compressed, and at the same time, the movable block drives the positioning block to move, so that the positioning block passes through the through hole of the limit frame and enters the interior of the limit frame, and then the limit frame is inserted into the installation frame, and then the handle is released. The rebound force of the spring pushes the two movable blocks away from each other, so that the movable block drives the positioning block to be inserted into the positioning hole of the installation frame, and then the limit frame is limited and fixed. When the prism body needs to be disassembled, the two handles are pulled to make the handles close to each other to make the positioning block disengage from the positioning hole of the installation frame, and then the limit frame can be pulled out from the installation frame, thereby quickly replacing the prism body, improving the replacement efficiency, and being more practical.

[0005] The bottom surface of the positioning block is an inclined surface. When the staff installs the prism body, the limit frame is directly inserted into the installation frame. The inclined surface of the bottom surface of the positioning block contacts the top surface of the installation frame, thereby driving the positioning block to enter the limit frame. At the same time, the positioning block drives the movable block to compress the spring. When the bottom surface of the limit frame contacts the bottom surface of the installation frame, the rebound force of the spring pushes the movable block to move, so that the movable block drives the positioning block to be inserted into the positioning hole of the installation frame to complete the positioning, further improving the convenience of installation.

[0006] A through hole is opened in the center of the movable block, and a guide column is arranged through the through hole in the center of the movable block. The cross section of the guide column is adapted to the cross section of the through hole of the movable block. Both ends of the guide column are fixed to the inner wall of the limit frame. The movable block can slide along the length direction of the guide column, thereby ensuring the stability of the moving process of the movable block.

[0007] A micro motor is arranged on one side of the bottom surface of the support platform, and the output end of the micro motor passes through the bottom surface of the support platform and extends to the inside of the driving frame, and a driving gear is arranged on the output end of the micro motor, and a driven gear is installed at the center of the inner part of the driving frame, and the driving gear is meshed with the driven gear, and the upper end center of the driven gear is connected to the center of the lower surface of the rotating disk. When the prism body is rotated, the existing prism placement frame usually limits the prism body by the damping force of the damping block, but the damping block will wear out more after being used for a long time, and the damping effect will gradually decrease, resulting in the inability to stably limit it. The staff starts the micro motor, and the output end of the micro motor drives the driving gear to rotate, and the driving gear drives the driven gear to rotate, and the driven gear drives the rotating disk to rotate, so that the rotating disk drives the prism body to rotate.

[0008] A protective frame is arranged on the surface of the micro motor, which can prevent rainwater from corroding the micro motor and increase the service life of the device.

[0009] A serrated structure is provided at the bottom of the bracket, which can improve the grip and stability.

[0010] In summary, compared with the prior art, the present application includes at least one of the following beneficial technical effects:

[0011] 1. When the utility model is used, when the staff needs to install the prism body, first pull the two handles with their fingers to make the two handles close to each other, and at the same time, the handles drive the connecting block and the movable block to move synchronously. When the movable blocks are close to each other, the spring is compressed, and at the same time, the movable block drives the positioning block to move, so that the positioning block passes through the through hole of the limit frame and enters the inside of the limit frame, and then the limit frame is inserted into the installation frame, and then the handles are released. The resilience of the spring pushes the two movable blocks away from each other, so that the movable block drives the positioning block to be inserted into the positioning hole of the installation frame, and then the limit frame is limited and fixed. When the prism body needs to be disassembled, the two handles are pulled to make the handles close to each other to make the positioning block disengage from the positioning hole of the installation frame, and then the limit frame can be pulled out from the installation frame, so that the prism body can be quickly replaced, the replacement efficiency is improved, and the practicality is stronger.
