Description

Technical Field

[0001] This utility model relates to the field of plastic bracket technology, and in particular to an outdoor aluminum base plastic bracket. Background Technology

[0002] Plastic brackets are made primarily of plastic and are used to support and fix other objects or structures to maintain their stability and integrity. For example, plastic screen brackets are used for electronic devices such as computers and televisions, providing stable support, adjustable height and angle, reducing neck and eye fatigue, improving viewing experience, and increasing work efficiency. Another example is LED all-copper full-color RGB brackets, which use PPA112 plastic material to make special light effect lamp beads for stage lighting, vehicle lights, etc.

[0003] For example, Chinese Patent Publication No. CN 214279469 U discloses an LED module with a plastic bracket, including a metal base, a face mask, and a lamp board disposed between the metal base and the face mask. The plastic bracket is fixed between the lamp board and the metal base, and the face mask covers the lamp board and is fixed to the plastic bracket by self-tapping screws. This application eliminates the need for machining threads on the face mask by setting a plastic bracket between the lamp board and the metal base, and fixing the face mask to the plastic bracket with self-tapping screws. Furthermore, the plastic bracket can be mass-produced simultaneously with the metal base using molds, resulting in high production efficiency and saving processing costs.

[0004] As can be seen from existing technologies, when installing a PCB board and a plastic bracket together, a large number of bolts are required for fixing, making the installation process very cumbersome and time-consuming, resulting in poor installation efficiency. Furthermore, after the PCB board and the plastic bracket are installed together, the plastic bracket obstructs the PCB board. If the side of the PCB board with LED lights needs to be fully exposed for maintenance, the use of a large number of bolts makes it difficult to separate the plastic bracket from the PCB board, which also makes the maintenance of the PCB board very inconvenient. Utility Model Content

[0005] The main purpose of this utility model is to provide an outdoor aluminum base plastic bracket, which aims to solve the technical problems of the existing plastic bracket and PCB board being too troublesome to install and the PCB board being very inconvenient to maintain.

[0006] This utility model proposes an outdoor aluminum base plastic bracket, including an aluminum base body, a PCB board body, and a plastic bracket body in the form of a hollowed-out mesh. The PCB board body is located above the aluminum base body, and several LED lights are connected to the surface of the PCB board body. The plastic bracket body is located above the PCB board body, and several hooks are fixed on the plastic bracket body. Several holes are opened on the PCB board body, and the hooks correspond one-to-one with the holes. Shrinkage grooves are opened on both sides of the hooks. Limiting blocks extending out of the hooks are provided in the shrinkage grooves, and electromagnetic adsorption components are provided in the shrinkage grooves.

[0007] Each electromagnetic adsorption assembly includes a guide rod, a sliding block, a return spring, an electromagnet, and a magnetic block. Two guide rods are provided, and each guide rod is fixed within the shrinkage groove. The sliding blocks are slidably connected to the guide rods. The limiting blocks are fixed to adjacent sliding blocks. Two return springs are provided, each fitted around the guide rod. One end of each return spring is connected to the inner side of the sliding block, and the other end is connected to the inner wall of the shrinkage groove. The electromagnet is connected to the inner wall of the shrinkage groove. The magnetic block is embedded within the sliding block, and each electromagnet corresponds to an adjacent magnetic block.

[0008] Preferably, the lower end face of the limiting block is inclined, and the upper end face of the limiting block is planar.

[0009] Preferably, the limiting block is made of ABS material.

[0010] Preferably, the hook has a through hole in the middle for fixing the face mask.

[0011] Preferably, one of the hooks has a button battery embedded inside.

[0012] Preferably, one of the hooks has a groove on one side of its upper end, and a tactile switch is installed in the groove, the tactile switch being connected in series with a button battery.

[0013] Preferably, wires are embedded inside both the plastic bracket body and the hook, and the electromagnets are connected in series with the tactile switch via wires.

[0014] Preferably, the plastic support body is made of thermally conductive plastic material.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. By installing multiple hooks on the plastic bracket body, inserting the hooks into the card holes, and then using limit blocks to limit the movement, the hooks are prevented from separating from the card holes, thus facilitating the quick installation of the plastic bracket body onto the PCB board body. This effectively reduces the hassle of bolting the plastic bracket body to the PCB board body, greatly improving installation efficiency.

[0017] 2. By setting up an electromagnetic adsorption component, when the plastic bracket body needs to be removed from the PCB body, the electromagnet is energized and magnetically adsorbs the magnetic blocks, which facilitates the retraction of all the limit blocks into the shrink groove. At this time, it is convenient to remove the hook from the card hole, and thus convenient to remove the plastic bracket body, which facilitates more comprehensive maintenance of the PCB body.

[0018] 3. By designing the plastic bracket body as a hollowed-out mesh, it provides a large heat dissipation space for the PCB board. Furthermore, the plastic bracket body is made of thermally conductive plastic material, so it has good thermal conductivity, which helps to effectively improve the heat dissipation effect on the PCB board.

[0032] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0033] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0034] like Figures 1-11 As shown, this application provides an outdoor aluminum-based plastic bracket, including an aluminum base body 1, a PCB board body 2, and a plastic bracket body 3 with a hollowed-out mesh pattern. The PCB board body 2 is located above the aluminum base body 1, and several LED lights 6 are connected to the surface of the PCB board body 2. The plastic bracket body 3 is located above the PCB board body 2, and several hooks 4 are fixed on the plastic bracket body 3. Several holes 5 are opened on the PCB board body 2, and the hooks 4 correspond one-to-one with the holes 5. Both sides of the hooks 4 have shrink grooves 8, and each shrink groove 8 is provided with a limiting block 7 extending out of the hook 4. Each shrink groove 8 is provided with an electromagnetic adsorption component, and each electromagnetic adsorption component includes a guide rod 1. 0. Sliding block 9, return spring 11, electromagnet 12, and magnetic block 13. Each guide rod 10 has two members, and each guide rod 10 is fixed in the contraction groove 8. Each sliding block 9 is slidably connected to the guide rod 10. Each limiting block 7 is fixed to the adjacent sliding block 9. Each return spring 11 has two members, and each return spring 11 is fitted around the guide rod 10. One end of each return spring 11 is connected to the inner side of the sliding block 9, and the other end is connected to the inner wall of the contraction groove 8. Each electromagnet 12 is connected to the inner wall of the contraction groove 8. Each magnetic block 13 is embedded in the inner side of the sliding block 9, and each electromagnet 12 corresponds to the adjacent magnetic block 13. The lower end face of the limiting block 7 is inclined, and the upper end face of the limiting block 7 is flat.

[0035] When the PCB board body 2 is mounted on the aluminum base body 1, and the plastic bracket body 3 needs to be installed together with the PCB board body 2, align the hooks 4 one by one with the holes 5, and then insert the hooks 4 into the holes 5. During this process, since the lower end face of the limiting block 7 is inclined, after the inclined surface of the lower end face of the limiting block 7 contacts the opening of the hole 5, the limiting block 7 will be pushed into the shrinkage groove 8 by the thrust. At this time, the limiting block 7 will push the sliding block 9 to move together, and the sliding block 9 will slide along the guide rod 10. The guide rod 10 limits the sliding of the sliding block 9, which helps to ensure the stability of the movement of the sliding block 9 and the limiting block 7. At the same time, the sliding block 9 will compress the return spring 11 until the hook 4 drives the limiting block 7 to pass smoothly through the hole 5. Then the limiting block 7 will no longer be pushed into the shrinkage groove 8. Then, the rebound force of the return spring 11 will drive the sliding block 9 and the limiting block 7 to move out of the shrinkage groove 8 and reset, so that the upper surface of the limiting block 7 abuts against the bottom of the PCB board body 2, thereby preventing the hook 4 from separating from the hole 5 and avoiding the separation of the plastic bracket body 3 from the PCB board body 2. In summary, this facilitates the quick installation of the plastic bracket body 3 on the PCB board body 2, effectively reducing the trouble of bolting the plastic bracket body 3 and the PCB board body 2, and greatly improving the installation efficiency.

[0036] In this embodiment, a button battery 14 is embedded inside one of the hooks 4, and a groove 15 is opened on one side of the upper end of one of the hooks 4. A tactile switch 16 is installed in the groove 15. The tactile switch 16 is connected in series with the button battery 14. Wires are embedded inside both the plastic bracket body 3 and the hook 4. The electromagnets 12 are connected in series with the tactile switch 16 through the wires.

[0037] By setting up an electromagnetic adsorption component, when the plastic bracket body 3 needs to be removed from the PCB body, the tactile switch 16 in the activation groove 15 is pressed by an external tool pin. Since the tactile switch 16 is connected in series with the button battery 14, and the electromagnet 12 is connected in series with the button battery 14 through a wire, after the tactile switch 16 is activated, the button battery 14 energizes the electromagnet 12. After the electromagnet 12 is energized, it magnetically attracts the magnetic block 13. The magnetic block 13 pulls the sliding block 9 to slide along the guide rod 10. The sliding block 9 will then compress the return spring 11 again, thereby... The sliding block 9 drives the limiting block 7 to retract into the shrinkage groove 8. Since all the electromagnets 12 are energized and attract the corresponding magnetic blocks 13, it is convenient to drive all the limiting blocks 7 to retract into the shrinkage groove 8 until the hook 4 can be smoothly pulled out from the hole 5. The plastic bracket is then lifted up, making it easy to remove the hook 4 from the hole 5, and thus easily disassemble the plastic bracket body 3, completely exposing the PCB board body 2 with the LED light 6, which facilitates more comprehensive maintenance of the PCB board body 2.

[0038] The limiting block 7 is made of ABS material.

[0039] By making the limiting block 7 from ABS material, a commonly used plastic material with good strength and plasticity, the impact resistance of the limiting block 7 is effectively guaranteed, avoiding the problem of the limiting block 7 being easily damaged due to insufficient impact resistance.

[0040] The hook 4 has a through hole 17 for fixing the mask, which runs vertically through the middle.

[0041] By providing a face mask fixing hole 17 in the middle of the hook 4, it is convenient to install the face mask through the face mask fixing hole 17.

[0042] In this embodiment, it includes an aluminum base body 1, a PCB board body 2, and a plastic support body 3 with a hollowed-out mesh shape. The plastic support body 3 is made of thermally conductive plastic material.

[0043] By setting the plastic bracket body 3 in a hollowed-out mesh shape, when the plastic bracket body 3 and the PCB board body 2 are installed together, the contact surface between the plastic bracket body 3 and the PCB board body 2 is small, thus providing a large heat dissipation space for the PCB board body 2. Furthermore, the plastic bracket body 3 is made of thermally conductive plastic material. Thermally conductive plastic is a composite material composed of engineering plastics or general plastics with added high thermal conductivity reinforcing materials. It has the heat transfer properties of metals and ceramics, while retaining other advantages of ordinary plastics, giving it excellent thermal conductivity and low specific gravity. Therefore, the plastic bracket body 3 has good thermal conductivity, which is conducive to effectively improving the heat dissipation effect on the PCB board body 2.
