Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of brackets, and specifically relates to a laser calibration bracket. Background Technology
[0002] Existing green laser alignment instruments typically require a dedicated calibration bracket to improve positioning accuracy. This bracket mainly consists of three parts: a base, a column, and a mounting platform. The column adopts an inner and outer double-rod nested structure, which is tightened to the outer rod by rotating a threaded sleeve to adjust the support height of the inner rod. The mounting platform is used to fix the green laser alignment instrument and uses a damping shaft structure to adjust the pitch angle, facilitating precise control of the laser irradiation direction.
[0003] During use, due to the flat structure of the base, the flat bottom cannot adapt to various working scenarios, such as metal surfaces or gravel ground, resulting in its low applicability. Utility Model Content
[0004] The purpose of this invention is to provide a laser calibration bracket, which aims to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A laser calibration bracket includes a support component comprising a base plate and a bracket. A fixing plate is fixedly connected to the top of the base plate. A first link and a second link are rotatably connected to the inner side of the fixing plate via a damping shaft. A third link is rotatably connected to the end of the first link away from the fixing plate. A fourth link is rotatably connected to the end of the second link away from the fixing plate. A connecting assembly is rotatably connected to the outer sides of the third and fourth links. A limiting component includes a fixing block, which is fixedly connected to the inside of the base plate. An insert rod is slidably connected to the inside of the fixing block. A sliding plate is fixedly connected to the inner side of the insert rod. The outer side of the sliding plate is fixedly connected to the inner side of the fixing block by a spring.
[0007] In a preferred embodiment of this utility model, the connecting assembly includes a rotating seat, which is rotatably connected to the outside of the third link and the fourth link, and a gripper is fixedly connected to the inside of the rotating seat.
[0008] As a preferred embodiment of this utility model, the edge of the gripper is arc-shaped, and the bottom arc edges converge on a line.
[0009] In a preferred embodiment of this utility model, the connection between the third link and the rotating seat is located above the connection between the fourth link and the rotating seat, and is disposed on its inner side.
[0010] In a preferred embodiment of this utility model, the connection between the first link and the fixed plate is located inside the connection between the second link and the fixed plate, and the two are at the same height.
[0011] As a preferred embodiment of this utility model, the second link and the third link are provided with limit pivots inside, and the two can rotate relative to each other through the limit pivots.
[0012] In a preferred embodiment of this utility model, holes are provided at corresponding positions of the gripper and the insertion rod, and the diameter of the insertion rod corresponds to the size of the opening inside the gripper.
[0013] As a preferred embodiment of this utility model, the bottom of the base plate is provided with a sliding groove, and the width of the middle slider of the sliding plate corresponds to the width of the sliding groove.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] 1.

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0026] Example 1
[0027] Reference Figures 1-4 This is the first embodiment of the present invention. This embodiment provides a laser calibration bracket, including a support component, including a base plate 10 and a bracket 11. A fixing plate 12 is fixedly connected to the top of the base plate 10. A first connecting rod 13 and a second connecting rod 14 are rotatably connected to the inner side of the fixing plate 12 via a damping shaft. A third connecting rod 15 is rotatably connected to the end of the first connecting rod 13 away from the fixing plate 12. A fourth connecting rod 16 is rotatably connected to the end of the second connecting rod 14 away from the fixing plate 12. A connecting assembly 17 is rotatably connected to the outer sides of the third connecting rod 15 and the fourth connecting rod 16.
[0028] Specifically, through the interaction between multiple links, the connecting component 17 can be flipped and folded 180 degrees. At the same time, in conjunction with the rotation of the damping shaft, it can be fixed at multiple angles, thereby enabling the bracket 11 to be adjusted and used in various environments.
[0029] Furthermore, the connecting assembly 17 includes a rotating seat 171, which is rotatably connected to the outside of the third link 15 and the fourth link 16. A gripper 172 is fixedly connected to the inside of the rotating seat 171. The edge of the gripper 172 is arc-shaped, and the bottom arc edges converge on a line.
[0030] The rotating seat 171 is used for receiving and rotating connections, and is also responsible for supporting the gripper 172. The design of the curved edge and pointed bottom of the gripper 172 allows it to be easily inserted into the ground in soft soil.
[0031] Preferably, the connection between the third link 15 and the rotating seat 171 is located above the connection between the fourth link 16 and the rotating seat 171, and is disposed inside it. The connection between the first link 13 and the fixing plate 12 is located inside the connection between the second link 14 and the fixing plate 12, and the two are at the same height. The second link 14 and the third link 15 are provided with limiting shafts inside, and the two can rotate relative to each other through the limiting shafts.
[0032] It should be noted that the four linkage structures work together to allow the gripper 172 to easily rotate 180 degrees. At the same time, the partially bent linkage structure allows for rotation with a short stroke, reducing the space required for adjustment and storage.
[0033] In use, the gripper 172 is initially positioned vertically upwards relative to the top of the base plate 10. By rotating the gripper 172 via a damping shaft connected to the first link 13 and the second link 14, the first link 13, the second link 14, the third link 15, and the fourth link 16 will slowly tilt outwards, allowing the gripper 172 to gradually rotate until it reaches the desired angle. Once this is achieved, rotation stops, and the gripper 172 is fixed in place. Multiple grippers 172 can be individually adjusted to suit various environments, such as being clamped onto pipes, pressed against stairs, or held against metal surfaces, stones, or even uneven surfaces. The gripper 172 can be adjusted according to the specific environment.
[0034] Example 2
[0035] Reference Figures 5-6 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a limiting component, including a fixing block 20. The fixing block 20 is fixedly connected to the inside of the base plate 10. An insert rod 21 is slidably connected inside the fixing block 20. A slide plate 22 is fixedly connected to the inner side of the insert rod 21. The outer side of the slide plate 22 is fixedly connected to the inner side of the fixing block 20 by a spring 23. A hole is opened at the corresponding position of the gripper 172 and the insert rod 21. The diameter of the insert rod 21 corresponds to the size of the opening in the gripper 172. A sliding groove is opened at the bottom of the base plate 10. The width of the middle slider of the slide plate 22 corresponds to the width of the sliding groove.
[0036] Specifically, when the pointed end of the gripper 172 points to the bottom, the insert rod 21 will be inserted into the gripper 172, restricting its rotation and keeping it in a vertically downward state. At this time, it can be inserted into soft soil to prevent it from rotating on its own.
[0037] When in use, when the gripper 172 rotates, it will first contact the insertion rod 21, causing the insertion rod 21 to slide inward and the spring 23 to stretch. When the insertion rod 21 can be inserted into the gripper 172, the spring 23 will return to its original position, driving the insertion rod 21 into the gripper 172. At this time, the gripper 172 cannot swing and can be directly inserted into the soil.
[0038] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
