Description

Technical Field

[0001] This invention belongs to the field of composite insulation board technology, specifically relating to a support device for static design of prefabricated composite insulation boards. Background Technology

[0002] Composite insulation boards are composite panels made by combining insulation materials with structural panels. Due to their lightweight, excellent thermal insulation performance, and ease of assembly and construction, they have been widely used in the field of prefabricated buildings.

[0003] The announcement number CN224133965U discloses a composite insulation board support device, which belongs to the field of composite insulation board support technology. The key technical points of the device include an insulation board body, a fixing component movably connected to the bottom of the surface of the insulation board body, and connecting components movably connected to both sides of the fixing component. The fixing component includes an L-shaped fixing plate.

[0004] The aforementioned application document describes how a specific specification of insulation board is clamped and fixed between the movable plate and the L-shaped fixed plate using an L-shaped fixed plate, a movable plate, a screw, and a threaded sleeve, to achieve rapid fixing of the insulation board. However, this method can only be used with insulation boards of a specific specification and with the same width. When the widths of the two insulation boards are different, it is impossible to achieve uniform clamping, which can easily lead to loosening on one side, uneven force, and displacement of the insulation board.

[0010] Furthermore, the two inclined grooves and the movable rod are symmetrically distributed around the central axis of the moving plate, and the sliding shafts A on both sides are slidably connected inside the inclined grooves.

[0011] Furthermore, the inner side of the limiting plate is provided with a sliding groove A, and slider A and slider B are slidably connected inside the sliding groove A. A movable telescopic rod is assembled between slider A and slider B. Slider A and slider B are fixedly connected. A rotating cylinder is rotatably connected to the inner side of the limiting plate. An L-shaped rod is fixedly connected to the upper end of the moving plate. A spiral groove is provided on the outer wall of the L-shaped rod. A sliding shaft B is rotatably connected to the inner wall of the rotating cylinder. The sliding shaft B is slidably connected inside the spiral groove. A cam plate is fixedly sleeved on the outer wall of the rotating cylinder. Horizontal plates are fixedly connected to both sides of slider A. A swing rod is rotatably connected to the front end of slider A through a pin. Sliding grooves B are provided on the outer walls of both sides of the swing rod. Sliding rods slide through the upper ends of both sides of the horizontal plates. Rollers are rotatably connected to the bottom ends of the sliding rods. A sliding shaft C is rotatably connected to the outer wall of the sliding rods. The sliding shaft C is slidably connected inside the sliding groove B.

[0012] Furthermore, a spring C is fixedly connected between slider A and slider B, and slider B is located at the bottom of the cam plate and fits against it.

[0013] Furthermore, a torsion spring is fixedly connected to the front end of the slider A, and the other end of the torsion spring is fixedly connected to the inner side of the swing rod.

[0014] Furthermore, the inner side of the limiting plate is provided with a receiving groove, and a rectangular frame is fixedly connected to the inner wall of the receiving groove. A lamp holder is slidably connected inside the rectangular frame. An installation block A is fixedly connected to the outer side of the limiting plate. A linkage rod is rotatably connected to the outer wall of the installation block A via a pin. A linkage groove A and a linkage groove B are provided on the inner side of the linkage rod.

[0016] The advantages of this application are:

[0017] (1) This application sets up a movable plate, a linkage plate, an inclined groove, a movable rod and a spring in cooperation. When the movable rod on one side stops moving due to contact with a wider raw material plate, the movable plate continues to move forward and compresses the spring on that side. At the same time, the sliding shaft A on the stopped side slides backward in the inclined groove. The inclined surface of the inclined groove generates a lateral force pointing towards the center of the movable plate, which pulls the linkage plate to slide towards the center, thereby pushing the movable rod on the other side to continue to extend until both positioning plates are tightly fitted with the raw material plate, which can adapt to raw material plates of different widths.

[0018] (2) This application achieves automatic pressing of the upper surface of the raw material plate through the linkage of L-shaped rod, spiral groove, rotating cylinder, cam plate, slider and swing rod; when both rollers contact the raw material plate, the swing rods on both sides complete the pressing simultaneously, which can automatically adapt to raw material plates of different thicknesses, effectively prevent the raw material plate from tilting or shifting during processing or testing, and improve the support stability.

[0019] (3) This application realizes the automatic extension and switching control of the lighting device through the cooperation structure of L-shaped rod, sliding shaft, linkage rod and proximity switch. When the L-shaped rod moves forward with the moving plate, the sliding shaft pushes the lamp holder out of the receiving groove through the linkage rod. After the lamp holder reaches the predetermined position, the proximity switch automatically triggers the lighting lamp to light up. When the moving plate moves backward to reset, the linkage rod drives the lamp holder to return to the receiving groove in the opposite direction, and the lighting lamp automatically turns off.

[0030] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of the present application. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative effort should fall within the scope of protection of the present application.

[0031] Example 1, as Figures 1-3 As shown, a support device for static design of prefabricated composite insulation board includes a workbench 1, a support leg 2 fixedly connected to the bottom of the workbench 1, and a limit plate 3 fixedly connected to the upper end of the workbench 1.

[0032] A fixed block 41 is fixedly connected to the upper end of the workbench 1. An electric telescopic rod 42 is fixedly connected to the outer wall of the fixed block 41. A connecting block 43 is fixedly connected to the output end of the electric telescopic rod 42. A moving rod 44 slides through the middle of the fixed block 41. One end of the moving rod 44 is fixedly connected to the inner side of the connecting block 43. A moving plate 45 is fixedly connected to the other end of the moving rod 44. A linkage plate 46 is provided at the upper end of the moving plate 45. Two inclined grooves 48 are opened on the inner side of the linkage plate 46. Movable rods 49 slide through both sides of the moving plate 45. A positioning plate 410 is fixedly connected to the inner side of the movable rod 49. A sliding shaft A411 is fixedly connected to the upper end of the movable rod 49.

[0033] The upper end of the movable plate 45 is fixedly connected to the slide rail 412, and the linkage plate 46 is slidably connected to the upper end of the movable plate 45 through the slide rail 412. By setting the slide rail 412, it can be ensured that the linkage plate 46 slides smoothly along a straight line on the movable plate 45, avoiding deviation or jamming, and ensuring the transmission accuracy between the inclined groove 48 and the sliding shaft A411.

[0034] A spring A413 is fixedly connected to the outer wall of the movable plate 45, and a circular block 414 is fixedly connected to the outer end of the movable rod 49. The other end of the spring A413 is fixedly connected to the circular block 414. By setting the spring A413, it can provide buffering and force storage when the movable rod 49 is blocked, and automatically pull the movable rod 49 to reset when the movable plate 45 moves backward, reducing manual intervention.

[0035] The two inclined grooves 48 and the movable rod 49 are symmetrically distributed around the central axis of the movable plate 45, and the sliding shafts A411 on both sides are slidably connected inside the inclined grooves 48. By symmetrically distributing the inclined grooves 48 and the movable rod 49, the sliding shafts A411 on both sides can slide synchronously in the inclined grooves 48, ensuring that the movements of the positioning plates 410 on both sides are coordinated and consistent, and achieving uniform clamping of the raw material plate.

[0036] When the above equipment is used, first place the two raw material boards of the assembled composite insulation board on the upper end of the workbench 1, so that one side of the two raw material boards is tightly attached to the inner side of the limiting plate 3, and the other side of the two raw material boards is located inside the two positioning plates 410 respectively. Then, start the electric telescopic rod 42, and its output end pulls the connecting block 43 to drive the moving rod 44 to move towards the raw material board. The moving plate 45 moves closer, and at this time, the movable rods 49 on both sides of the moving plate 45 and the positioning plate 410 will also move towards the raw material board. At the same time, the linkage plate 46 also moves towards the raw material board under the drive of the slide rail 412.

[0037] After moving a certain distance, the wider side of the raw material plate will first contact the positioning plate 410 on that side. After the positioning plate 410 on that side is blocked, the movable rod 49 on that side will stop moving. However, the electric telescopic rod 42 continues to pull the moving plate 45 towards the raw material plate. Therefore, the moving plate 45 continues to move forward. At this time, a relative displacement occurs between the movable rod 49 on the stopped side and the moving plate 45 that continues to move forward. The spring A413 on that side is gradually compressed, and the spring force gradually increases.

[0038] At the same time, the sliding shaft A411 on the stop side slides backward relative to the linkage plate 46 in the inclined groove 48. The sliding shaft A411 presses against the inclined surface of the inclined groove 48, and the inclined surface generates a reaction force on the sliding shaft A411. The horizontal component of this reaction force points outward of the moving plate 45. According to the principle of action and reaction forces, the sliding shaft A411 simultaneously applies a transverse force of equal magnitude and opposite direction to the inclined groove 48. This transverse force points towards the center of the moving plate 45, pushing the linkage plate 46 to slide along the slide rail 412 towards the center of the moving plate 45.

[0039] When the linkage plate 46 slides toward the center, the inclined groove 48 on the other side moves toward the center. The inclined surface of the inclined groove 48 pushes the sliding shaft A411 on the other side forward, causing the movable rod 49 on the other side to extend toward the raw material plate, driving the positioning plate 410 on that side to continue to move forward until the positioning plate 410 on that side is also in close contact with the raw material plate.

[0040] When both positioning plates 410 are in contact with the raw material plate, if the moving plate 45 continues to move, both moving rods 49 will stop moving, and both springs A413 will be further compressed. At this time, the elastic force stored in the spring A413 is converted into a clamping force on the raw material plate, so that the two raw material plates are stably clamped on the worktable 1.

[0041] When the electric telescopic rod 42 stops moving and maintains its position, the moving plate 45 is stationary, and the springs A413 on both sides are in a compressed state, maintaining continuous pressure on the raw material plate. When the electric telescopic rod 42 pushes the moving plate 45 backward, the springs A413 gradually return to their original length, pushing the movable rod 49 and the positioning plate 410 away from the raw material plate, thus completing the unlocking.

[0042] Example 2, as Figures 4-7 As shown, based on Embodiment 1, a sliding groove A51 is provided on the inner side of the limiting plate 3. Sliding sliders A52 and B53 are slidably connected inside the sliding groove A51. A movable telescopic rod 54 is assembled between sliders A52 and B53. Sliding sliders A52 and B53 are fixedly connected. A rotating cylinder 55 is rotatably connected to the inner side of the limiting plate 3. An L-shaped rod 56 is fixedly connected to the upper end of the moving plate 45. A spiral groove 57 is provided on the outer wall of the L-shaped rod 56. A sliding shaft B58 is rotatably connected to the inner wall of the rotating cylinder 55. The sliding shaft B58 slides... Inside the spiral groove 57, a cam plate 59 is fixedly sleeved on the outer wall of the rotating cylinder 55. A horizontal plate 510 is fixedly connected to both sides of the slider A52. The front end of the slider A52 is rotatably connected to a swing rod 511 through a pin. Slide grooves B512 are opened on the outer walls of both sides of the swing rod 511. A slide rod 513 slides through the upper ends of both sides of the horizontal plate 510. A roller 514 is rotatably connected to the bottom end of the slide rod 513. A slide shaft C515 is rotatably connected to the outer wall of the slide rod 513. The slide shaft C515 is slidably connected inside the slide groove B512.

[0043] A spring C516 is fixedly connected between slider A52 and slider B53. Slider B53 is located at the bottom of cam plate 59 and is in contact with it. By setting spring C516, slider B53 can be reset upward after cam plate 59 is disengaged from slider B53, which prepares for the next downward pressing action. At the same time, it avoids slider B53 from falling due to gravity and affecting the retraction of swing rod 511.

[0044] A torsion spring 517 is fixedly connected to the front end of slider A52. The other end of the torsion spring 517 is fixedly connected to the inner side of swing rod 511. By setting the torsion spring 517, the swing rod 511 can always maintain the tendency to swing inward, ensuring that the swing rod 511 can quickly press against the upper surface of the raw material plate after the roller 514 stops descending, and can automatically reset when it is retracted.

[0045] When the above equipment is used, when the moving plate 45 moves towards the raw material plate, the L-shaped rod 56 moves accordingly, the spiral groove 57 pushes the sliding shaft B58, causing the rotating drum 55 to drive the cam plate 59 to rotate. The cam plate 59 pushes the slider B53 downward above the slider B53, and the slider B53 drives the slider A52 to descend together.

[0046] When slider A52 descends, the horizontal plate 510 drives the sliding rod 513 to descend. The roller 514 on the side with the thicker raw material plate stops descending after contacting the surface of the raw material plate. When slider A52 continues to descend, the sliding rod 513 on that side no longer continues to descend, and the roller 514 rolls upward relative to it. This causes the swing rod 511 on that side to swing towards the raw material plate under the action of the torsion spring 517 and press against the upper end surface of the raw material plate. The roller 514 corresponding to the thinner raw material plate on the other side has not yet contacted the surface of the raw material plate, so the swing rod 511 on that side has not yet moved.

[0047] When the moving plate 45 continues to move until both rollers 514 contact the surface of the raw material plate on their respective sides, both swing rods 511 press the upper surface of the corresponding raw material plate under the action of the torsion spring 517, thus completing the pressing of the upper end of the raw material plates of different thicknesses.

[0048] When the moving plate 45 moves backward, the L-shaped rod 56 moves in the opposite direction, the rotating cylinder 55 reverses, the cam plate 59 reverses and disengages upward from the slider B53, the slider B53 resets upward under the action of the spring C516, driving the slider A52 to rise, the horizontal plate 510 and the slide bar 513 rise accordingly, the roller 514 leaves the surface of the raw material plate, and the swing rod 511 automatically retracts under the action of the torsion spring 517, releasing the clamping.

[0049] Example 3, as Figures 8-9As shown, based on Embodiment 1 or Embodiment 2, the inner side of the limiting plate 3 is provided with a receiving groove 61, the inner wall of the receiving groove 61 is fixedly connected with a rectangular frame 62, the inside of the rectangular frame 62 is slidably connected with a lamp holder 63, the outer side of the limiting plate 3 is fixedly connected with a mounting block A64, the outer wall of the mounting block A64 is rotatably connected with a linkage rod 65 through a pin, the inner side of the linkage rod 65 is provided with a linkage groove A66 and a linkage groove B67, one end of the L-shaped rod 56 movably passes through the limiting plate 3 and is rotatably connected with a sliding shaft D68, the outer wall of the lamp holder 63 is fixedly connected with a mounting block B69, the inner side of the mounting block B69 is fixedly connected with a sliding shaft E610, and a proximity switch 611 is provided on the side of the inner wall of the rectangular frame 62 away from the lamp holder 63.

[0050] Sliding shaft D68 is slidably connected inside the linkage groove B67, and sliding shaft E610 is slidably connected to the inner wall of the linkage groove A66. By setting sliding shafts D68 and E610 in the linkage grooves B67 and A66 respectively, the linear motion of the L-shaped rod 56 can be converted into the rotation of the linkage rod 65, and then into the linear sliding of the lamp holder 63, realizing two-way conversion of power. The structure is compact and the transmission is reliable.

[0051] In practical use, when one end of the L-shaped rod 56 moves outward, the sliding shaft D68 on its outer wall also moves accordingly. The sliding shaft D68 slides inside the linkage groove B67, pushing the linkage rod 65 to rotate around the mounting block A64. When the linkage rod 65 rotates, the linkage groove A66 moves accordingly. The inner wall of the linkage groove A66 pushes the sliding shaft E610, causing the sliding shaft E610 to slide along the linkage groove A66. This drives the mounting block B69 and the lamp holder 63 to slide outward from inside the receiving groove 61 along the rectangular frame 62. When the lamp holder 63 slides out to the proximity switch 611, the proximity switch 611 is triggered, and the lighting automatically turns on to provide auxiliary lighting for the joint of the raw material plate on the workbench 1.

[0052] When one end of the L-shaped rod 56 moves inward to reset, the sliding shaft D68 slides in the opposite direction, pushing the linkage rod 65 to rotate in the opposite direction. The linkage groove A66 drives the lamp holder 63 to retract into the receiving groove 61 along the rectangular frame 62 via the sliding shaft E610. After the lamp holder 63 leaves the sensing range of the proximity switch 611, the proximity switch 611 is disconnected, and the lighting automatically turns off.

[0053] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
