A flat plate installation angle adjusting device

Abstract

This invention relates to a flat plate mounting angle adjustment device, comprising a frame, a spindle mounted on the frame, a clamping assembly mounted on the spindle, and a braking assembly mounted on the frame. The clamping assembly secures the flat plate to the spindle, and then rotating the spindle causes the flat plate to rotate with it, thus adjusting the mounting angle. After the flat plate angle is adjusted to the desired position, the spindle slides vertically and presses against a contact plate. Since the contact plate is located between the hinge shaft and the spindle, the pressure exerted by the spindle on the contact plate is transmitted to the brake pads, causing the brake pads on both sides to rotate and converge towards the central spindle around the hinge point, rather than opening to the sides. This locks and secures the spindle, preventing changes in the flat plate angle due to spindle rotation, and thus locking the flat plate at the adjusted angle for subsequent flat plate installation.

Description

Technical Field

[0001] This invention relates to the technical field of flat plate mounting, and in particular to a flat plate mounting angle adjustment device. Background Technology

[0002] The installation of large flat panel structures often involves adjusting the angle of the panel. However, due to the large mass of these panels, it is difficult to maintain their current orientation after adjustment to complete subsequent installation work. Summary of the Invention

[0003] To at least partially solve the aforementioned problems in the prior art, the present invention provides a flat plate mounting angle adjustment device.

[0004] A flat plate mounting angle adjustment device includes a frame, a spindle mounted on the frame, a clamping assembly mounted on the spindle, and a braking assembly mounted on the frame.

[0005] The spindle is horizontally rotatable on the frame around its own axis and can slide vertically on the frame. The clamping assembly is used to fix the plate on the spindle so that the plate angle can be adjusted as the spindle rotates. The braking assembly is used to lock and fix the spindle after the plate angle adjustment is completed.

[0006] The braking assembly includes two brake pads symmetrically arranged on both sides of the main shaft and an abutment disposed on the brake pads. The brake pads are arranged vertically and one end is hinged to the frame. The abutment is located between the hinge point of the brake pad and the horizontal line connecting the main shaft, so that when the main shaft slides vertically against the abutment, the other end of the brake pad clamps and fixes the main shaft.

[0007] Optionally, the brake assembly further includes a torsion spring disposed on the frame, the torsion spring being located between the two brake pads, the two free ends of the torsion spring being respectively connected to the two brake pads, the two brake pads being opened away from the sides of the main shaft by the torsion spring, and the opening angle being such that the main shaft is placed between the two brake pads.

[0008] Optionally, the main shaft is further provided with a pressure member, the pressure member being positioned corresponding to the abutment member;

[0009] The abutment is located between the hinge point of the brake pad and the vertical line connecting the main shaft, and the pressure member is at least partially located between the abutment and the vertical line connecting the main shaft.

[0010] Optionally, the abutment is located between the hinge point of the brake pad and the vertical line connecting the main shaft, and away from the hinge point.

[0011] Optionally, a knurled shaft is coaxially provided on the main shaft at a position corresponding to the brake pad, and the radius of the knurled shaft is larger than the radius of the main shaft;

[0012] A friction layer is provided on the side wall of the brake pad that corresponds to and is close to the knurled shaft.

[0013] Optionally, the clamping assembly includes a sleeve, two clamping plates, and a first locking member. The sleeve can be fixedly sleeved on the main shaft. The two clamping plates are symmetrically arranged on the sleeve and a placement groove is formed between the two clamping plates. The placement groove is used to place a flat plate, and the first locking member is used to fix the flat plate in the placement groove.

[0014] Optionally, the first locking member includes a first locking bolt, and a first threaded hole is provided on the side wall of one of the clamping plates, and the first locking bolt can be threaded into the first threaded hole;

[0015] A washer is fixedly provided at the screw end of the first locking bolt. The edge of the washer protrudes away from the first locking bolt, so that the washer as a whole has a bowl-shaped structure.

[0016] Optionally, the clamping assembly further includes a second locking member, wherein the sleeve is slidably disposed on the spindle and can be detachably fixed on the spindle by means of the second locking member;

[0017] The second locking component includes a second locking bolt. The sleeve has a second threaded hole, and the second locking bolt can be threaded into the second threaded hole. The main shaft has a plurality of blind holes at intervals along its own length direction, which correspond to the second threaded hole. The diameter of the blind holes is the same as the outer diameter of the second locking bolt.

[0018] Optionally, multiple second threaded holes are provided at intervals along the length of the sleeve, and the distance between two adjacent second threaded holes is an integer multiple of the distance between two adjacent blind holes.

[0019] Optionally, the side wall of the spindle where the blind hole is formed is configured as a planar structure, and an abutment is provided on the side of the sleeve where the second threaded hole is formed, the second threaded hole passing through the abutment, and the side of the abutment corresponding to the blind hole is also configured as a planar structure.

[0020] In a flat plate installation angle adjustment device of the present invention, the flat plate is fixed on the main shaft by a clamping assembly, and then the main shaft is rotated to make the flat plate rotate with the main shaft, thereby achieving installation angle adjustment. After the flat plate angle is adjusted to the required position, the main shaft slides vertically and presses against the abutment. Since the abutment plate is located between the hinge shaft and the main shaft, the pressure of the main shaft against the abutment is transmitted to the brake pads, causing the brake pads on both sides to rotate and move towards the main shaft in the middle around the hinge point, rather than opening to both sides, thereby achieving locking and fixing of the main shaft to prevent the flat plate angle from changing due to the rotation of the main shaft, and thus locking the flat plate at the adjusted angle for subsequent flat plate installation.

[0025] Figure 5 This is a schematic diagram of the frame structure according to an embodiment of the present invention. Detailed Implementation

[0026] The following reference Figures 1-5 This invention describes a flat plate mounting angle adjustment device.

[0027] refer to Figures 1-5 This invention provides a flat plate mounting angle adjustment device, including a frame 5, a spindle 3 mounted on the frame 5, a clamping assembly 2 mounted on the spindle 3, and a braking assembly 4 mounted on the frame 5. The spindle 3 is horizontally rotatable on the frame 5 about its own axis and can slide vertically on the frame 5. The clamping assembly 2 is used to fix the flat plate 1 on the spindle 3 so that the angle of the flat plate 1 can be adjusted as the spindle 3 rotates. The braking assembly 4 is used to lock and fix the spindle 3 after the angle of the flat plate 1 is adjusted.

[0028] Furthermore, the brake assembly 4 includes two brake pads 41 symmetrically arranged on both sides of the main shaft 3 and an abutment 4a disposed on the brake pads 41. The brake pads 41 are arranged vertically and one end is hinged to the frame 5. The abutment 4a is located between the hinge point of the brake pads 41 and the horizontal line connecting the main shaft 3, so that when the main shaft 3 slides vertically against the abutment 4a, the other end of the brake pads 41 clamps and fixes the main shaft 3.

[0029] The angle adjustment device uses clamping assembly 2 to fix plate 1 onto spindle 3, and then rotates spindle 3 to make plate 1 rotate with spindle 3, thereby adjusting the installation angle. After the angle of plate 1 is adjusted to the required position, spindle 3 slides vertically and presses against abutment 4a. Since the abutment plate is located between hinge shaft 52 and spindle 3, the pressure of spindle 3 against abutment 4a is transmitted to brake pad 41, causing the brake pads 41 on both sides to rotate around the hinge point toward the spindle 3 in the middle, rather than opening to the sides, thereby locking and fixing spindle 3 to prevent the angle of plate 1 from changing due to the rotation of spindle 3, and thus locking plate 1 at the adjusted angle for subsequent installation of plate 1.

[0030] In one specific example, the brake assembly 4 is provided in two sets, located at both ends of the main shaft 3.

[0031] In some embodiments of the present invention, the brake assembly 4 further includes a torsion spring 8 disposed on the frame 5, the torsion spring 8 being located between two brake pads 41, and the two free ends of the torsion spring 8 being respectively connected to the two brake pads 41. The two brake pads 41 are opened away from the sides of the main shaft 3 by the torsion spring 8, and the opening angle allows the main shaft 3 to be placed between the two brake pads 41.

[0032] When the main shaft 3 is not pressing against the abutment 4a, the torsion spring 8 provides a continuous spreading force to the brake pads 41 on both sides, keeping the brake pads 41 in an open state. When the main shaft 3 presses against the abutment 4a, causing the brake pads 41 to close, the torsion spring 8 undergoes elastic deformation and stores potential energy. When the main shaft 3 releases the abutment force, the torsion spring 8 releases the potential energy, driving the brake pads 41 to automatically return to their open state. By setting the torsion spring 8, the automatic return of the brake pads 41 is achieved, simplifying the operation process. At the same time, it ensures that the brake pads 41 can open stably, and the opening angle allows the main shaft 3 to be placed between the two brake pads 41, avoiding unnecessary friction between the main shaft 3 and the brake pads 41 when the main shaft slides vertically.

[0033] In some embodiments of the present invention, the abutment 4a is located between the hinge point of the brake pad 41 and the vertical line connecting the main shaft 3. A pressure member 3c is also provided on the main shaft 3, the pressure member 3c being positioned corresponding to the abutment 4a and at least partially located between the abutment 4a and the vertical line connecting the main shaft 3.

[0034] When the spindle 3 slides vertically downwards, the pressure member 3c enables the spindle 3 to press against the abutment member 4a. The setting of the pressure member 3c is equivalent to locally increasing the radial dimension or changing the outer contour of the spindle 3, thereby ensuring that the spindle 3 can accurately and stably press against the abutment member 4a when sliding down, avoiding slippage or uneven wear caused by alignment deviation.

[0035] In a specific example, the pressure component 3c is a pressure roller, which is coaxially fixedly mounted on the main shaft 3. The radius of the pressure roller is larger than the radius of the main shaft 3.

[0036] In some embodiments of the present invention, the abutment 4a is located between the hinge point of the brake pad 41 and the vertical line connecting the main shaft 3, and is far from the hinge point. The farther the abutment 4a is from the hinge point, the easier it is for the brake pad 41 to move around the hinge point toward the main shaft 3 when the abutment 4a is pressed.

[0037] In some embodiments of the present invention, the brake pad 41 includes an arc segment 412 and a hinge segment 411, the hinge segment 411 being hinged to the frame 5, and the arc segment 412 being used to clamp the spindle 3. By setting the position of the brake pad 41 clamping the spindle 3 as an arc structure, the shape of the brake pad 41 and the spindle 3 are matched, thereby making the locking and fixing of the spindle 3 more secure.

[0038] In some embodiments of the present invention, a knurled shaft 3d is coaxially disposed on the main shaft 3 at a position corresponding to the brake pad 41, and the radius of the knurled shaft 3d is larger than the radius of the main shaft 3. The brake pad 41 is clamped onto the knurled shaft 3d to achieve locking and fixing of the main shaft 3. By providing the knurled shaft 3d, on the one hand, the larger radius of the knurled shaft 3d facilitates the clamping of the brake pad 41; on the other hand, the surface of the knurled shaft 3d can increase the friction between the knurled shaft 3d and the brake pad 41, making the locking and fixing of the brake pad 41 to the main shaft 3 more reliable.

[0039] At this time, the torsion spring 8 ensures that the opening angle of the brake pad 41 is such that the knurled shaft 3d is placed between the two brake pads 41.

[0040] Similarly, in some embodiments of the present invention, a friction layer 9 is provided on the sidewall of the brake pad 41 corresponding to and close to the knurled shaft 3d, to further increase the friction between the brake pad 41 and the knurled shaft 3d. Optionally, the friction layer 9 is made of rubber.

[0041] In some embodiments of the present invention, the abutting member 4a includes two abutting plates, which are respectively disposed on two brake pads 41.

[0042] In some embodiments of the present invention, a hinge seat 51 is provided on the frame 5, and the brake pad 41 is hinged to the hinge seat 51 via a hinge shaft 52.

[0043] In some embodiments of the present invention, the frame 5 includes a base 5b and two mounting plates 5c vertically fixed at both ends of the base 5b. Vertical grooves 5a are symmetrically provided on the two mounting plates 5c. The two ends of the main shaft 3 are respectively inserted into the vertical grooves 5a, so that the main shaft 3 can rotate around its own axis in the vertical grooves 5a and slide vertically along the vertical grooves 5a.

[0044] At this time, the brake pad 41 is hinged to the base 5b, that is, the hinge seat 51 is fixedly set on the base 5b.

[0045] In some embodiments of the present invention, the clamping assembly 2 includes a sleeve 21, two clamping plates 2a, and a first locking member. The sleeve 21 can be fixedly sleeved on the spindle 3. The two clamping plates 2a are symmetrically arranged on the sleeve 21, and a placement groove is formed between the two clamping plates 2a. The placement groove is used to place the plate 1. The first locking member is used to fix the plate 1 in the placement groove. By adopting the above structure, the plate 1 can be clamped and fixed between the two clamping plates 2a, which is simple in structure and convenient in operation.

[0046] In one specific example, two sets of clamping components 2 are provided, and the two sets of clamping components 2 are spaced apart along the length direction of the spindle 3, so as to fix the plate 1 more firmly.

[0047] In some embodiments of the present invention, the first locking member includes a first locking bolt 6, and a first threaded hole 2b is provided on the side wall of one of the clamping plates 2a, and the first locking bolt 6 can be threaded into the first threaded hole 2b. After the plate 1 is placed vertically in the placement groove, the plate 1 can be fixed by rotating the first locking bolt 6 until the threaded end of the first locking bolt 6 abuts against the other clamping plate 2a. The whole process is simple and convenient to operate.

[0048] In some embodiments of the present invention, a washer 7a is fixedly provided at the screw end of the first locking bolt 6. The edge of the washer 7a protrudes away from the first locking bolt 6, so that the washer 7a has an overall bowl-shaped structure. By providing the washer 7a, the wear of the screw end of the first locking bolt 6 on the plate 1 can be reduced. At the same time, by setting the washer 7a into a bowl-shaped structure, when the washer 7a abuts against the plate 1, the washer 7a will have an adsorption effect on the plate 1, thereby making the plate 1 more securely fixed.

[0049] In some embodiments of the present invention, the gasket 7a is fixedly connected to the first locking bolt 6 by a rivet 6a, and the end of the rivet 6a is located inside the edge of the gasket 7a. By riveting the gasket 7a to the first locking bolt 6, it is convenient to replace the gasket 7a after wear and tear from long-term use.

[0050] In some embodiments of the present invention, the clamping assembly 2 further includes a second locking member, and the sleeve 21 is slidably disposed on the main shaft 3 and can be detachably fixed on the main shaft 3 by means of the second locking member. By setting the sleeve 21 and the main shaft 3 to be slidably connected, the position of the sleeve 21 of the two sets of clamping assemblies 2 can be adjusted according to the size of the plate 1 to accommodate the fixing of more sizes of plate 1.

[0051] In some embodiments of the present invention, the second locking element includes a second locking bolt 7. A second threaded hole 2d is provided on the sleeve 21, and the second locking bolt 7 can be threaded into the second threaded hole 2d. A plurality of blind holes 3b, corresponding to the second threaded holes 2d, are spaced apart along the length of the main shaft 3. The diameter of the blind holes 3b is the same as the outer diameter of the second locking bolt 7. When it is necessary to fix the sleeve 21 onto the main shaft 3, the second threaded hole 2d on the sleeve 21 is aligned with the blind holes 3b on the main shaft 3, and then the second locking bolt 7 is rotated so that the screw end of the second locking bolt passes through the blind hole 3b.

[0052] Optionally, both the first locking bolt 6 and the second locking bolt 7 are butterfly bolts to facilitate personnel to rotate the first locking bolt 6 and the second locking bolt 7.

[0053] In some embodiments of the present invention, multiple second threaded holes 2d are provided at intervals along the length of the sleeve 21, and the distance between two adjacent second threaded holes 2d is an integer multiple of the distance between two adjacent blind holes 3b, thereby avoiding the inability to fix the sleeve 21 due to interference or misalignment between the second threaded holes 2d and the blind holes 3b.

[0054] In some embodiments of the present invention, the sidewall of the spindle 3 with the blind hole 3b is configured as a first planar structure 3a, and an abutment is provided on the side of the sleeve 21 with the second threaded hole 2d, the second threaded hole 2d penetrating the abutment. The side of the abutment corresponding to the blind hole 3b is configured as a second planar structure 2c. By configuring the side of the abutment corresponding to the blind hole 3b and the sidewall of the spindle 3 with the blind hole 3b as planar structures, on the one hand, the contact area is increased, the pressure in the contact area is reduced, and local stress concentration caused by point contact or line contact is avoided, thereby reducing the risk of deformation of the sidewall of the spindle 3 and the area around the blind hole 3b. On the other hand, the planar fit of the two has good positioning and anti-rotation functions. After the plane of the abutment and the plane of the spindle 3 are in contact with each other, the circumferential sliding or rotation of the abutment relative to the spindle 3 can be effectively restricted.

[0055] Optionally, the abutment platform and sleeve 21 are integrated.

[0056] In summary, the specific operation process of this angle adjustment device is as follows: First, fix the frame 5 to the ground or other operating platform. The specific fixing structure is not shown, but anchor bolts or welding can be used. Next, adjust the distance between the two sleeves 21 according to the size of the plate 1 to be installed, and fix the sleeves 21 to the main shaft 3 using the second locking bolt 7. Then, place the plate 1 between the two clamping plates 2a, and fix the plate 1 with the first locking bolt 6. At this point, the fixed connection between the plate 1 and the main shaft 3 is completed. It should be noted that when fixing the plate 1, the main shaft 3 is locked and fixed by the brake assembly 4. Then, lift the main shaft 3 upward, and the pressure member 3c disengages from the pressure on the abutment member 4a, thereby opening the two brake pads 41 and losing the locking and fixing of the main shaft 3. At this time, the main shaft 3 can be rotated around its own axis as needed, and the plate 1 on it will also rotate accordingly until the plate 1 is rotated to the required installation angle. Then the main shaft 3 is slowly lowered. When the pressure member 3c is lowered to press against the abutment member 4a, the brake pads 41 on both sides will move towards the middle under the action of the pressure, so that the brake pads 41 clamp the knurled shaft 3d and lock the main shaft 3. At this time, the installation angle of the plate 1 is also locked.

[0057] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
