Description

Technical Field

[0001] This utility model relates to the field of lighting mechanism device technology, specifically to a lamp plate locking structure. Background Technology

[0002] In lighting systems, lamp panels (or driver boards) are typically fixed using screws. When screws are used to fix the lamp panel to the mounting surface, in some cases the mounting surface and the lamp panel are not parallel, and there is an angle between them. Generally, the angle between the lamp panel and the mounting surface is within 10°. Forcing the lamp panel to fit with the mounting surface using screws can easily lead to cracking, open circuits, and other problems, increasing safety risks. If the angle exceeds 10°, specific components need to be designed to lock the lamp panel to the mounting surface. However, locking with specific components has problems such as poor versatility and needs to be improved. Utility Model Content

[0003] To address at least one of the aforementioned technical deficiencies, this utility model provides the following technical solution:

[0004] This application discloses a lamp panel locking structure, including a pressure plate and a bracket. The bracket includes a plate, a column, and a top plate. The top plate and the column are both located on one surface of the plate. The column is connected to the plate and the top plate is provided on one side of the column. The pressure plate is detachably connected to the column and at least part of the pressure plate protrudes outward from the peripheral wall of the column to form a clamping engagement with the top plate below.

[0005] The locking structure designed in this scheme consists of a bracket plate that is fixed to the surface to be installed. A pressure plate on the bracket is connected to the column. The portion of the pressure plate protruding from the column's perimeter cooperates with the top plate below to clamp and fix the light panel. The light panel does not directly contact the surface to be installed. During the fixing process, there is basically no need to consider the size of the angle between the light panel and the surface to be installed. With reasonable control of the clamping force, phenomena such as light panel cracking are greatly reduced, resulting in low safety risks. In addition, this locking mechanism can be used to clamp and fix the light panel at different angles, making it highly versatile.

[0006] For pressure plates, the connection between the pressure plate and the column can be fixed by means of fitting, snap-fit, threaded engagement, screws or other fasteners, and the choice can be made according to the needs.

[0007] The shape of the pressure plate is not subject to too many restrictions, as long as it can be connected to the column and partially protrudes from the column's perimeter to clamp the top plate below.

[0008] Preferably, the pressure plate includes a connected body and a protrusion. The body is detachably connected to the column. The protrusion protrudes outward from the outer wall of the column and is located along the length of the top plate. The bottom surface of the protrusion is arc-shaped or conical. The protrusion and the lower top plate form a clamping fit. The body can be plate-shaped, cylindrical, or irregularly shaped. The protrusion is located along the length of the top plate and its bottom surface is arc-shaped or conical, thus forming a point contact or line contact relationship with the lamp panel. The angle between the lamp panel and the column can be adjusted as needed, such as changing from a perpendicular position to an angle of 80°. The lamp panel can be rotated to fine-tune its position as required.

[0009] Furthermore, protrusions are provided opposite each other along the length of the top plate, with two points of contact to better improve clamping stability.

[0010] Furthermore, the main body is cylindrical and fits onto the end of the column. A protrusion is provided at the bottom of the main body. The cylindrical shape makes it easy to fit onto the column and facilitates docking.

[0011] Furthermore, the pressure plate is fixed to the column by fasteners, which are threaded into the column. The fasteners, such as screws, simplify the connection structure.

[0012] Furthermore, the pressure plate is provided with a through hole, and the end of the fastener passes through the through hole and connects to the column.

[0013] Furthermore, it also includes a lamp plate, which is fitted onto the column and clamped by a pressure plate protruding outward from the column's perimeter wall and a lower top plate. If the lamp plate has a hole formed in it, the column passes through the hole to form a nested relationship.

[0014] Furthermore, a limiting plate is provided on the peripheral wall of the column, and the column passes through the insertion hole formed on the lamp plate, and a groove is provided on the wall of the insertion hole. The limiting plate extends into the groove to restrict the rotation of the lamp plate relative to the column. Adding the limiting plate helps to restrict the rotation of the lamp plate relative to the column.

[0015] Furthermore, the limiting plate and the top plate are arranged in a cross shape, and gaps are reserved between the limiting plate and the corresponding groove wall and between the column and the insertion hole wall. The cross shape and the reserved gaps make it convenient for the lamp plate to be flipped relative to the column to make fine adjustments to the position, making it more flexible to use.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. The present invention designs a lamp panel locking structure, in which the bracket aligns with the surface to be installed, and the lamp panel is clamped and fixed on the bracket. The lamp panel does not directly contact the surface to be installed, so there is no need to consider the angle between the lamp panel and the surface to be installed during installation, making it more versatile.

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0027] Example 1

[0028] like Figure 3 As shown, in this example, a lamp panel locking structure includes a pressure plate 2 and a bracket 1. The bracket 1 includes a plate 10, a column 11, and a top plate 12. The top plate 12 and the column 11 are both located on the upper surface of the plate 10. The column 11 is connected to the plate 10, and the top plate 12 is located on one side of the column 11. The column, top plate, and plate can be integrally injection molded. The side end of the top plate 12 can maintain a gap with the peripheral wall of the column 11 or be directly connected, as in this example, the side of the top plate 12 is connected to the peripheral wall of the column 11.

[0029] like Figure 3 As shown, the top plate 12 is like a strip, the column 11 is like a cylinder, and the top plate 12 is formed on both sides of the column 11. The pressure plate 2 is like a cylinder, and the pressure plate 2 is directly fitted onto the top of the column 11. The peripheral wall of the pressure plate 2 is the part that protrudes outward from the peripheral wall of the column. The bottom surface of the peripheral wall of the pressure plate is clamped to the top surface of the top plate below.

[0030] During installation, if the lamp plate 4 has pre-formed insertion holes, the lamp plate is fitted onto the column through the insertion holes. Then, the pressure plate is fitted onto the column, and self-tapping screws are used as fasteners to pass through the end of the pressure plate and connect with the threaded connection of the column. The bottom surface of the peripheral wall of the pressure plate and the top surface of the lower top plate clamp the lamp plate in the middle, and the plate of the bracket is attached to and fixed to the surface to be installed.

[0031] Example 2

[0032] like Figure 1 , Figure 2 , Figure 4 , Figure 5 As shown, in this example, a lamp panel locking structure includes a pressure plate 2 and a bracket 1. The bracket 1 includes a plate 10, a column 11, and a top plate 12. The top plate 12 and the column 11 are both located on the upper surface of the plate 10. The column 11 is connected to the plate 10, and the top plate 12 is located on one side of the column 11. The column, top plate, and plate can be integrally injection molded. The side end of the top plate can maintain a gap with the peripheral wall of the column or be directly connected, as in this example, the side of the top plate 12 is connected to the peripheral wall of the column 11.

[0033] The top plate 12 is strip-shaped, and the column 11 is cylindrical. Top plates 12 are formed on opposite sides of the column 11. The pressure plate 2 includes a connected body 21 and a protrusion 22. The body 21 is cylindrical. During installation, the body 21 is fitted onto the end of the column 11. Self-tapping screws are used as fasteners 3, which pass through the through hole at the end of the body and are screwed into the end of the column to fix the body to the column.

[0034] At the bottom of the main body 21, protrusions 22 are formed on opposite end faces of the cylindrical opening. These protrusions 22 are all located along the length of the top plate 12 and are situated outside the perimeter of the column 11. The bottom surface of each protrusion 22 is either arc-shaped or conical. Figure 5 The bottom surface of the convex part 22 shown is conical, and the convex part 22 and the top plate 12 below form a clamping fit. The bottom surface of the convex part 22 and the lamp plate 12 are in point contact or line contact relationship.

[0035] The lamp panel 4 has a recessed hole 41 formed on it. The end of the column passes through the recessed hole to fit into it. The bottom surface of the lamp panel abuts against the top plate. Then, a pressure plate is installed, so that the bottom surface of the protrusion of the pressure plate abuts against the top surface of the lamp panel to form a clamp. A gap is reserved between the wall of the recessed hole and the peripheral wall of the column, so that force can be applied to the end of the lamp panel to make the lamp panel rotate relative to the column at a certain angle. Figure 1 The central lamp panel is perpendicular to the column, and force is applied to make the angle between the lamp panel and the column 80°, which improves flexibility.

[0036] A limiting plate 13 can also be added. The limiting plate 13 is formed on the peripheral wall of the column 11. The limiting plate 13 and the top plate 12 are distributed in a cross shape. The groove 42 is formed inward at the opposite hole wall of the insertion hole 41 of the lamp plate 4. When the column is inserted into the insertion hole of the lamp plate, the limiting plate extends into the corresponding groove. The rotation of the lamp plate relative to the column (with the axial center line of the column as the rotation center line) is restricted by the limiting plate.

[0037] like Figure 5 As shown, a gap is reserved between the bottom wall of the groove at the corresponding hole wall and the side of the corresponding limiting plate. When the lamp plate is flipped relative to the column (such as when the length direction of the top plate is parallel to the rotation center line), it is convenient to make fine adjustments to the position.

[0038] During installation, the light panel is fitted onto the column through the insertion hole, and then the pressure plate is fitted onto the column. Self-tapping screws are used as fasteners, passing through the end of the pressure plate and threaded into the column. The protrusion of the pressure plate and the top plate below clamp the light panel in the middle, and the bracket plate is attached to and fixed to the surface to be installed.

[0039] The above are merely preferred embodiments 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 within its protection scope. 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 its protection scope.
