Description

Technical Field

[0001] This utility model relates to the field of 3D laser scanner technology, and in particular to a manual raising bracket for a 3D laser scanner. Background Technology

[0002] As a high-precision measuring device, 3D laser scanners play an irreplaceable role in various fields such as architectural surveying, cultural relic preservation, and industrial inspection. To ensure that the scanning range covers the target area and obtains accurate data, the scanner usually needs to be mounted on an adjustable-height stand. By changing the vertical height of the stand, it can adapt to different measurement scenario requirements. Therefore, the height adjustment performance of the stand directly affects the working efficiency and measurement applicability of the 3D laser scanner.

[0003] Chinese utility model patent CN222650994U discloses a manually adjustable height support for a 3D laser scanner, comprising a base, a support frame mounted on top of the base, two symmetrical positioning components connected to the top of the support frame, a lifting frame connected inside the support frame, and several sets of equidistant fixing plates mounted on both outer sides of the lifting frame, each fixing plate having a through slot inside. The positioning components include a rotating plate connected to the outside of the support frame, with a telescopic rod and a first spring mounted inside the rotating plate. A positioning plate is mounted on one end of the telescopic rod and the first spring, and a push plate is mounted on the outer side of the positioning plate. A first slot is formed on the outer side of the rotating plate. The height of the lifting frame can be adjusted by positioning it inside the support frame using the two positioning components.

[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist: During the adjustment process of the above-mentioned device, when adjusting the height, the staff needs to simultaneously unlock and control the two sets of positioning components. On this basis, the lifting frame also needs to be moved up and down synchronously. This process often requires two staff members to work together to complete, which not only increases labor costs, but also further reduces adjustment efficiency due to the coordination problems of multiple people working together. Utility Model Content

[0005] To address the aforementioned problems, this invention provides a manually raised support for a 3D laser scanner.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a manual lifting bracket for a 3D laser scanner, comprising a base, characterized in that: a fixed tube is provided at the top of the base, a lifting tube is vertically slidably arranged inside the fixed tube, a mounting frame for mounting the 3D laser scanner is provided at the upper end of the lifting tube, a mounting frame is provided at the lower part of the lifting tube, and locking blocks are symmetrically and horizontally slidably arranged on the mounting frame. The lifting tube has a through groove corresponding to the locking block, and a plurality of locking grooves that cooperate with the locking block are vertically spaced on the inner wall of the fixed tube. A compression spring is provided on the mounting frame to provide outward sliding force for the locking block. An adjusting frame is vertically slidably arranged on the mounting frame. When the adjusting frame moves upward, it pushes the locking block inward. An adjusting rod is provided at the top of the adjusting frame, and an arched handle is provided on the bottom surface of the mounting frame. A control rod is vertically slidably arranged inside the arched handle, and the upper end of the adjusting rod passes through the mounting frame and is connected to the control rod.

[0007] By adopting the above technical solution, a locking block, a compression spring, and a locking slot are set up. The locking block is pushed outward by the compression spring and locks into the locking slot of the fixed tube, thereby stabilizing and limiting the vertical position of the lifting tube and ensuring the fixed position of the 3D laser scanner after installation. When the height needs to be adjusted, the operator places his palm on the arched handle and pulls the control lever upward. The adjustment lever drives the adjustment frame to move upward, and the adjustment frame simultaneously pushes the locking blocks on both sides inward, separating the locking blocks from the locking slots. At this time, the lifting tube can be easily moved up and down through the arched handle to adjust the height of the scanner. After adjusting to the target height, the control lever is released, and the compression spring automatically pushes the locking block outward, so that the locking block re-fits the corresponding locking slot precisely. The entire adjustment process is simple to operate and highly efficient, realizing convenient adjustment of the height of the 3D laser scanner.

[0008] Furthermore, the mounting bracket includes a fixed plate with both ends connected to the inner wall of the lifting tube. Two guide rods are horizontally spaced on both sides of the fixed plate. The length direction of the guide rods is perpendicular to the length direction of the fixed plate. Two guide holes are opened on the locking block. The locking block is slidably mounted on the two guide rods through the two guide holes. Four compression springs are respectively sleeved on the four guide rods. One end of the compression spring is connected to the fixed plate and the other end is connected to the corresponding locking block.

[0009] By adopting the above technical solution, a guide rod and a guide hole are set, and the guide rod and the guide hole slide together to provide guidance for the horizontal sliding of the block.

[0010] Furthermore, the card block is provided with adjustment shafts on both sides, and the adjustment frame includes two spaced adjustment plates. The adjustment plate has a first strip hole vertically opened in the middle, and the adjustment plate is vertically slidably connected to the fixed plate through the first strip hole. The adjustment plate has a second strip hole arranged at an inclination on both sides, and the second strip hole is slidably connected to the corresponding adjustment shaft. The two adjustment plates are connected by a connecting plate between the upper and lower plates of the fixed plate. The adjustment rod is set on the upper connecting plate.

[0011] By adopting the above technical solution, and setting up an adjusting shaft and adjusting plates, with the second strip-shaped hole slidingly engaging with the adjusting shaft of the locking block, the vertical lifting motion of the adjusting frame can be converted into the horizontal extension and retraction motion of the locking block. The two adjusting plates are synchronously connected through a connecting plate, ensuring that the movements of the adjusting plates on both sides are consistent, thereby driving the locking blocks on both sides to extend and retract synchronously.

[0012] Furthermore, the second strip-shaped hole is inclined from top to bottom toward the core of the rising tube.

[0013] By adopting the above technical solution, the second strip hole is inclined from top to bottom toward the core of the lifting tube. When the adjustment frame is pulled up, the inclined inner wall of the second strip hole can generate an inward pushing force on the adjustment shaft, which can drive the locking block to separate from the locking groove.

[0014] Furthermore, guide strips are vertically arranged on the inner walls of the two opposite sides of the first strip hole, and guide grooves are opened on the fixing plate corresponding to the guide strips and slidably connected to the guide strips.

[0015] By adopting the above technical solution, guide bars and guide grooves are set, and the guide bars and guide grooves slide together to further ensure the stability of the lifting and lowering of the regulating plate.

[0016] Furthermore, the slot is a triangular slot with one side of the slot wall parallel to the horizontal plane and located on the lower side of the inclined slot wall, and the block is a right-angled trapezoidal block that mates with the triangular slot.

[0017] By adopting the above technical solution, the horizontal groove wall on the lower side of the triangular groove cooperates with the horizontal bottom surface of the right trapezoidal block to form a stable support structure, which can effectively bear the weight of the 3D laser scanner, prevent the lifting tube from sliding down unexpectedly, and improve the load-bearing stability and safety of the bracket.

[0018] Furthermore, a fixing ring is fixedly sleeved on the rod body of the adjusting rod located inside the lifting tube near the mounting frame, and a return spring is sleeved on the rod body of the adjusting rod located between the fixing ring and the bottom of the mounting frame.

[0019] By adopting the above technical solution, a fixing ring and a reset spring are set. After the control lever is released, the elastic force of the reset spring can drive the adjusting rod and the adjusting frame to reset downward, so that the locking block can quickly cooperate with the locking slot under the action of the compression spring.

[0020] Furthermore, the arched handle has vertical grooves on its inner walls on both sides, and sliders are slidably disposed in the grooves. The two ends of the control rod are respectively connected to the two sliders.

[0021] By adopting the above technical solution, the slide provides guidance for the vertical sliding of the control rod.

[0022] In summary, this utility model has the following beneficial effects: In this application, a locking block, a compression spring, and a locking groove are provided. The locking block, under the pushing force of the compression spring, receives an outward force and locks itself in the locking groove of the fixed tube, thereby stably limiting the vertical position of the lifting tube and ensuring the fixed position of the 3D laser scanner after installation. When height adjustment is required, the operator places their palm on the arched handle and pulls the control lever upwards. The adjustment lever drives the adjustment frame upwards, and the adjustment frame simultaneously pushes the locking blocks on both sides inwards, separating the locking blocks from the locking grooves. At this time, the lifting tube can be easily moved up and down through the arched handle to adjust the scanner height. After adjusting to the target height, the control lever is released, and the compression spring automatically pushes the locking block outwards, allowing the locking block to re-fit precisely with the corresponding locking groove. The entire adjustment process is simple to operate and highly efficient, achieving convenient adjustment of the 3D laser scanner height. Attached Figure Description

[0025] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0026] like Figure 1-6 As shown in the figure, this application discloses a manual lifting bracket for a 3D laser scanner, including a base 10, a fixed tube 11, and a lifting tube 20. The fixed tube 11 is vertically disposed on the top of the base 10, and the lifting tube 20 is vertically slidably disposed within the fixed tube 11. A mounting frame 30 is disposed at the upper end of the lifting tube 20, and the top of the mounting frame 30 is used to mount the 3D laser scanner. A mounting bracket 40 is disposed in the lower part of the lifting tube 20, and locking blocks 50 are symmetrically and horizontally slidably disposed on the mounting bracket 40. The lifting tube 20 has a through groove 21 corresponding to the locking blocks 50 for the locking blocks 50 to pass through. A plurality of slots 12 that cooperate with the locking blocks 50 are vertically spaced on the inner wall of the fixed tube 11. A compression spring 51 is disposed on the mounting bracket 40 to provide outward sliding force for the locking blocks 50. Under the push of the compression spring 51, the locking blocks 50 are subjected to an outward force and are locked in the slots 12 of the fixed tube 11, thereby stabilizing and limiting the vertical position of the lifting tube 20 and ensuring that the position of the 3D laser scanner is fixed after installation. An adjustment frame 60 is vertically slidable on the mounting frame 40. When the adjustment frame 60 moves upward, it pushes the locking blocks 50 inward. An adjustment rod 70 is located at the top of the adjustment frame 60. An arched handle 31 is located on the bottom surface of the mounting frame 30. A control rod 32 is vertically slidable inside the arched handle 31. The upper end of the adjustment rod 70 passes through the mounting frame 30 and connects to the control rod 32. When the height needs to be adjusted, the operator places their palm on the arched handle 31 and pulls the control rod 32 upward. This causes the adjustment frame 60 to move upward through the adjustment rod 70. Simultaneously, the adjustment frame 60 pushes the locking blocks 50 on both sides inward, separating the locking blocks 50 from the slots 12. At this time, the lifting tube 20 can be easily moved up and down through the arched handle 31 to adjust the scanner height. After adjusting to the target height, the control rod 32 is released, and the compression spring 51 automatically pushes the locking blocks 50 outward, allowing the locking blocks 50 to re-fit precisely with the corresponding slots 12. The entire adjustment process is simple and efficient, enabling convenient adjustment of the height of the 3D laser scanner.

[0027] Specifically, the mounting bracket 40 includes a fixed plate 41 connected to the inner wall of the lifting tube 20 at both ends. Two guide rods 42 are horizontally spaced on both sides of the fixed plate 41. The guide rods 42 are horizontally arranged and their length direction is perpendicular to the length direction of the fixed plate 41. Two guide holes are provided on the locking block 50. The locking block 50 is slidably mounted on the two guide rods 42 through the two guide holes. The guide rods 42 slide in cooperation with the guide holes, providing guidance for the horizontal sliding of the locking block 50, effectively preventing offset during sliding, and ensuring that the locking block 50 is aligned with and engages with the locking slot 12. Four compression springs 51 are respectively sleeved on the four guide rods 42. One end of the compression spring 51 is connected to the fixed plate 41, and the other end is connected to the corresponding locking block 50.

[0028] During setup, the locking block 50 has adjusting shafts 52 on both sides. The adjusting frame 60 includes two spaced adjusting plates 61. A first strip-shaped hole 62 is vertically formed in the center of each adjusting plate 61, allowing it to slide vertically to the fixed plate 41 via the first strip-shaped hole 62. A second strip-shaped hole 63 is inclined on both sides of each adjusting plate 61, and is slidably connected to the corresponding adjusting shaft 52. The two adjusting plates 61 are connected to the upper and lower sides of the fixed plate 41 via a connecting plate 64. The adjusting rod 70 is mounted on the upper connecting plate 64. The second strip-shaped hole 63 slides with the adjusting shaft 52 of the locking block 50, converting the vertical lifting motion of the adjusting frame 60 into the horizontal extension and retraction motion of the locking block 50. The two adjusting plates 61 are synchronously connected via the connecting plate 64, ensuring consistent movement of both adjusting plates 61, thereby causing the locking blocks 50 to extend and retract synchronously. The second strip-shaped hole 63 is inclined from top to bottom towards the core of the lifting tube 20. When the adjusting bracket 60 is pulled upwards, the inclined inner wall of the second strip-shaped hole 63 exerts an inward pushing force on the adjusting shaft 52, which can cause the locking block 50 to separate from the locking groove 12. When the control lever 32 is released and the locking block 50 resets outwards under the action of the compression spring 51, the adjusting shaft 52 slides smoothly down along the inclined second strip-shaped hole 63, simultaneously causing the adjusting bracket 60 to automatically reset. Guide bars 65 are vertically provided on the inner walls of the opposite sides of the first strip-shaped hole 62, and guide grooves are provided on the fixing plate 41 corresponding to the guide bars 65, which are slidably connected to the guide bars 65. The sliding cooperation between the guide bars 65 and the guide grooves further ensures the stability of the lifting and lowering of the adjusting plate 61.

[0029] In its specific configuration, slot 12 is a triangular slot with one side wall parallel to the horizontal plane and located on the lower side of the inclined slot wall. The locking block 50 is a right-angled trapezoidal block that engages with the triangular slot. The horizontal slot wall on the lower side of the triangular slot engages with the horizontal base of the right-angled trapezoidal block, forming a stable support structure that effectively supports the weight of the 3D laser scanner, preventing the lifting tube 20 from accidentally sliding down and improving the support's load-bearing stability and safety. The inclined slot wall of the triangular slot engages with the inclined side of the locking block 50. When raising the lifting tube 20, the locking block 50 can naturally retract inward along the inclined slot wall, smoothly engaging into the next slot 12 without needing to deliberately pull the control lever 32, simplifying the raising operation. During lowering, simply pulling the control lever 32 separates the locking block 50 from the slot 12, balancing the convenience of raising and the controllability of lowering, further optimizing the user experience. When the card block 50 moves outward, if there is a vertical drop between the card block 50 and the card slot 12, the lifting tube 20 will drop slightly to ensure that the horizontal groove wall on the lower side of the triangular groove matches the horizontal bottom surface of the right trapezoidal block.

[0030] The adjusting rod 70 is located inside the lifting tube 20, near the mounting frame 30, and is fixedly fitted with a fixing ring 71. A return spring 72 is fitted onto the adjusting rod 70 between the fixing ring 71 and the bottom of the mounting frame 30. The upper end of the return spring 72 is connected to the bottom of the mounting frame 30, and the lower end is connected to the fixing ring 71. When the control rod 32 is released, the elastic force of the return spring 72 can drive the adjusting rod 70 and the adjusting frame 60 to return downwards, allowing the locking block 50 to quickly engage with the locking groove 12 under the action of the compression spring 51. The arched handle 31 has vertically opened grooves on its opposite inner walls, with sliders 73 sliding within these grooves. The two ends of the control rod 32 are connected to the two sliders 73 respectively. The grooves provide guidance for the vertical sliding of the control rod 32. The control rod 32 is connected to the arched handle 31 via the sliders 73 at both ends, resulting in more even force distribution and a smoother feel when the operator lifts the control rod 32.

[0031] Limiting grooves are provided on the inner walls of opposite sides of the fixed tube 11. There is a gap between the top surface of the limiting groove and the top surface of the fixed tube 11. A limiting block connected to the lower end of the lifting tube 20 is slidably installed in the limiting groove. When the lifting tube 20 is raised or lowered, the limiting block slides in the limiting groove to control the lifting stroke of the lifting tube 20 and prevent the lifting tube 20 from separating from the fixed tube 11.

[0032] The operating principle of the manual lifting bracket for a 3D laser scanner in this embodiment is as follows: When adjusting the height of the 3D laser scanner, the operator places their palm on the arched handle 31 and pulls the control rod 32 inside the handle upwards. The adjusting rod 70 connected to the control rod 32 drives the adjusting frame 60 inside the lifting tube 20 to move upwards. The adjusting frame 60 pushes the two side blocks 50 to retract inwards through the inclined second strip-shaped hole 63 and separates from the slot 12 of the fixed tube 11. At this time, the lifting tube 20 can be slid up and down to the target height through the arched handle 31. Then, the control rod 32 is released, and the compression spring 51 pushes the block 50 to reset outwards and cooperate with the slot 12. If there is a vertical drop between the block 50 and the slot 12, the lifting tube 20 will descend slightly to ensure that the horizontal bottom surface of the block 50 is in contact with the horizontal groove wall of the slot 12. At the same time, the reset spring 72 drives the adjusting rod 70 and the adjusting frame 60 to reset downwards, completing the height adjustment.

[0033] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
