Description

Technical Field

[0001] This utility model relates to the field of injection molded base plates, and in particular to an injection molded base plate with convenient fastener installation. Background Technology

[0002] Chinese Patent No. CN214945562U discloses a fixing structure for a base plate of an injection molded part, including a fastener. The fastener includes a main body with a first clamping part at one end and a second clamping part on the side of the main body near the first clamping part, forming a storage space between the first clamping part and the second clamping part. The fastener is installed on the base plate, and the base plate has a clamping area located within the storage space. One side wall of the clamping area is fitted to the storage space, and the first clamping part is riveted and pressed against the top surface of the base plate.

[0003] After the fasteners in the above structure are installed on the base plate and the first clamping part protrudes from the bottom surface of the base plate to the top surface of the middle base plate, the first clamping part is bent at the top surface of the base plate by riveting, so that the first clamping part presses against the top surface of the base plate, reducing the probability of the fasteners falling off the base plate after they are installed on the base plate. However, riveting the first clamping part requires the use of other machinery or tools, resulting in a high assembly cost between the base plate and the fasteners. Utility Model Content

[0004] This invention addresses the drawback of existing technologies where riveting the first clamping part requires additional machinery or tools, resulting in high assembly costs between the base plate and fasteners. It provides an injection-molded base plate that offers convenient fastener installation and lower installation costs.

[0005] To solve the above-mentioned technical problems, the present invention provides a solution through the following technical method:

[0006] An injection-molded base plate for easy fastener installation includes an injection-molded base plate, fasteners, and an anti-detachment component to prevent the fasteners from falling off the injection-molded base plate when they are installed on it. The anti-detachment component includes an extension plate vertically downward disposed at the bottom of the injection-molded base plate to restrict radial movement of the fasteners when they are installed on the injection-molded base plate, and a pressing block disposed at one end of the extension plate away from the injection-molded base plate to press one end of the fasteners against the bottom surface of the injection-molded base plate when they are installed on it.

[0007] By adopting the above solution, the vertically downward-extending extension plate on the bottom surface of the injection molded base plate can limit the radial movement of the fastener when it is installed on the injection molded base plate. Meanwhile, the pressing block located on the extension plate away from the injection molded base plate can press one end of the fastener against the bottom surface of the injection molded base plate when it is installed. This achieves the installation of the fastener and the injection molded base plate. The entire installation process of the fastener only requires installing the fastener onto the bottom surface of the injection molded base plate and ensuring that the surface of the fastener abuts against the bottom surface of the injection molded base plate. At this time, the extension plate on the bottom surface of the injection molded base plate will limit the radial movement of the fastener, and the pressing block located at the end of the extension plate away from the injection molded base plate will also press the fastener against the bottom surface of the injection molded base plate, thus completing the installation of the fastener and the injection molded base plate and reducing the cost required for the installation of the fastener and the injection molded base plate.

[0008] Preferably, the extension plate is circumferentially arranged around the bottom surface of the injection molded base plate with the mounting position of the fastener as the center, and the shape formed by the extension plate is the same as the shape of the fastener abutting the bottom surface of the injection molded base plate. At least two pressing blocks are provided, and they are circumferentially arranged on the opposite side surface of the extension plate.

[0009] By adopting the above scheme, the extension plate is circumferentially wrapped around the bottom surface of the injection molding base plate, so that the extension plate can radially limit the fasteners installed on the injection molding base plate. At least two pressing blocks are provided circumferentially on the extension plate to press the fasteners between the pressing blocks and the injection molding base plate, thereby fixing the fasteners and reducing the cost required for assembling the fasteners and the injection molding base plate.

[0010] Preferably, the extension plate is provided with relief grooves on both sides of the pressure block to facilitate deformation of the extension plate at the pressure block during the fastener installation to the injection molded base plate.

[0011] Using the above solution, the extension plate is provided with clearance grooves on both sides of the pressure block. The extension plate with the pressure block is designed to deform during the installation of the fasteners onto the injection molding base plate, thereby facilitating the installation of the fasteners between the pressure block and the injection molding base plate.

[0012] Preferably, the end of the pressing block away from the injection molding base plate is provided with an inlet component that facilitates the deformation of the extension plate by the fastener during the fastener installation onto the injection molding base plate.

[0013] Preferably, the inlet component includes an inlet ramp provided at the end of the pressing block away from the injection molding base plate.

[0014] Using the above method, during the process of installing the fastener onto the injection molded base plate, the fastener will abut against the guide ramp on the pressure block. Then, as the fastener continues to be installed, the fastener will squeeze the guide ramp, thereby causing the pressure block to drive the extension plate to deform, which facilitates the installation of the fastener between the pressure block and the injection molded base plate, thus fixing the fastener.

[0015] Preferably, a mating component is provided between the fastener sidewall and the extension plate to make the extension plate sidewall fit more tightly with the fastener sidewall and reduce the probability that the extension plate will detach from the fastener due to external force after the fastener is installed between the pressing block and the injection base plate.

[0016] Preferably, the mating component includes a first magnet embedded on the extension plate above the pressing block and a second magnet embedded on the fastener that is directly opposite to the first magnet and attracts each other when the fastener is installed between the pressing block and the injection molded base plate.

[0017] Using the above solution, the first magnet on the extension plate can attract the second magnet on the pressure block when the fastener is installed between the pressure block and the injection molded base plate, thereby making the side wall of the fastener and the side wall of the extension plate more tightly abut. At the same time, when the first magnet and the second magnet attract each other, the probability of the fastener falling off between the pressure block and the injection molded base plate when the extension plate is deformed by external force can also be reduced.

[0018] This utility model, by adopting the above technical solution, has significant technical effects: An extension plate extending vertically downwards from the bottom surface of the injection molding base plate can limit the radial movement of the fastener when it is installed on the injection molding base plate. Meanwhile, a pressing block located on the extension plate away from the injection molding base plate can press one end of the fastener against the bottom surface of the injection molding base plate when it is installed, thus achieving the installation between the fastener and the injection molding base plate. The entire installation process of the fastener only requires installing the fastener onto the bottom surface of the injection molding base plate and making the surface of the fastener abut against the bottom surface of the injection molding base plate. At this time, the extension plate on the bottom surface of the injection molding base plate will limit the radial movement of the fastener, and the pressing block located at the end of the extension plate away from the injection molding base plate will also press the fastener against the bottom surface of the injection molding base plate, thereby completing the installation between the fastener and the injection molding base plate and reducing the cost required for the installation of the fastener and the injection molding base plate.

[0026] Example

[0027] A type of injection-molded base plate that facilitates fastener installation, reference Figure 1 , Figure 5 The system includes an injection base plate 1, a fastener 2, and an anti-detachment component to prevent the fastener 2 from falling off the injection base plate 1 when it is installed on the injection base plate 1. The anti-detachment component includes an extension plate 3 vertically downwardly disposed at the bottom of the injection base plate 1 to restrict the radial movement of the fastener 2 when it is installed on the injection base plate 1, and a pressing block 4 disposed at one end of the extension plate 3 away from the injection base plate 1 to press one end of the fastener 2 against the bottom surface of the injection base plate 1 when it is installed on the injection base plate 1. In this embodiment, the fastener 2 is a nut, and a through hole 9 is provided on the injection base plate 1. When the nut is installed on the injection base plate 1, it is partially inserted into the through hole 9.

[0028] refer to Figures 1-2 , Figure 5 The extension plate 3 is circumferentially arranged around the bottom surface of the injection molded base plate 1 with the mounting position of the fastener 2 as the center. The shape formed by the extension plate 3 is the same as the shape of the fastener 2 abutting the bottom surface of the injection molded base plate 1. In this embodiment, the mounting position is circumferentially arranged around the bottom of the injection molded base plate 1 with the center of the through hole 9 as the center. In this embodiment, the nut between the injection molded base plate 1 and the pressing block 4 is rectangular. The shape of the extension plate 3 is the same as that of the nut, so as to prevent the nut from rotating under the action of the bolt when the bolt is screwed into the nut. At least two pressing blocks 4 are provided, and they are circumferentially arranged on the opposite side surface of the extension plate 3. In this embodiment, two pressing blocks 4 are provided and symmetrically arranged on both sides of the extension plate 3. On the extension plate 3, on both sides of the pressing block 4, there are relief grooves 5 to facilitate the deformation of the extension plate 3 at the pressing block 4 during the process of installing the fastener 2 to the injection molded base plate 1.

[0029] refer to Figure 1 , Figure 5The end of the pressing block 4 away from the injection base plate 1 is provided with an inlet component that facilitates the deformation of the extension plate 3 by the fastener 2 during the installation of the fastener 2 onto the injection base plate 1. The inlet component includes an inlet ramp 6 provided at the end of the pressing block 4 away from the injection base plate 1.

[0030] refer to Figures 2-5 A fitting component is provided between the side wall of the fastener 2 and the extension plate 3 to make the side wall of the extension plate 3 fit more tightly with the side wall of the fastener 2 and reduce the probability that the extension plate 3 will detach from the fastener 2 due to external force after the fastener 2 is installed between the pressing block 4 and the injection base plate 1. The fitting component includes a first magnet 7 embedded on the extension plate 3 above the pressing block 4 and a second magnet 8 embedded on the fastener 2 that is directly opposite to the first magnet 7 and attracts each other when the fastener 2 is installed between the pressing block 4 and the injection base plate 1. In this embodiment, the extension plate 3 above both pressing blocks 4 is provided with the first magnet 7, and the number and position of the second magnet 8 correspond one-to-one with the number and position of the first magnet 7.

[0031] The specific installation process of the fastener is as follows: When the fastener 2 needs to be installed on the injection base plate 1, firstly, the fastener 2 is installed on the bottom surface of the injection base plate 1. During the installation of the fastener 2 on the bottom surface of the injection base plate 1, one end of the fastener 2 will abut against the guide slope 6 on the pressing block 4. Then, as the fastener 2 continues to be installed, the fastener 2 will squeeze the guide slope 6. At this time, the pressing block 4 will drive the extension plate 3 to deform, thereby facilitating the installation of the fastener 2 on the injection base plate 1 and realizing the assembly between the fastener 2 and the injection base plate 1. When the fastener 2 is installed until its surface abuts against the bottom surface of the injection base plate 1, the second magnet 8 set on the fastener 2 will attract the first magnet 7 on the extension plate 3, making the surface of the fastener 2 and the surface of the extension plate 3 fit more tightly. At the same time, it can also reduce the probability that the fastener 2 will fall off between the pressing block 4 and the injection base plate 1 due to deformation of the extension plate 3 caused by external force.
