Abstract
Description
Technical Field
[0001] This utility model relates to the field of screw technology, specifically a multi-functional linkage screw. Background Technology
[0002] A screw is a common fastener used to tightly connect two or more objects together. It consists of a threaded shank and a head (such as hex head, Phillips head, flat head, etc.).
[0003] Screws have many applications, such as installation at the bottom of a horizontal suspended platform. Existing technology uses screws in conjunction with expansion tubes to ensure the stability of the screw after installation, but its load-bearing capacity is limited. When the household appliances to be installed are heavy, the contact between the screw and the suspended platform may still loosen over time, affecting the stability of actual use. Therefore, we propose a multi-functional linkage screw. Utility Model Content
[0004] The purpose of this utility model is to provide a multi-functional linkage screw to solve the problem mentioned in the background art. There are many application scenarios for screws, such as installation at the bottom of a horizontal hanging plate. The existing technology uses screws in conjunction with expansion tubes to ensure the stability of the screw after installation. However, its load-bearing capacity is limited. When the weight of the household appliances to be installed is large, the contact position between the screw and the hanging plate still loosens as the usage time increases, affecting the stability of actual use.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-functional linkage screw, including a screw head, a threaded rod, a reinforcing component, and a limiting component. The reinforcing component is installed on the surface of the threaded rod, and the limiting component is installed on the surface of the screw head. During the installation process, the threaded rod drives the reinforcing component to start and play a reinforcing role.
[0006] Preferably, the reinforcement component includes grooves and plastic bags. The surface of the threaded rod has four equally spaced grooves. A plastic bag is installed on the inner wall of the four grooves away from the screw head. The reinforcement component also includes guide rods and threaded columns. Guide rods are fixedly connected inside the four grooves. Threaded columns are slidably connected to the surface of the guide rods. The threads on the surface of the threaded columns are opposite in direction to the threads on the surface of the threaded rods.
[0007] Preferably, the limiting component includes slender bolts, and four equidistant slender bolts are movably connected to the top of the screw head, and both the slender bolts and the top of the screw head are provided with slots.
[0008] Preferably, the outer wall of the threaded post extends to the outside of the threaded rod.
[0009] Compared with the prior art, the beneficial effects of this utility model are:
[0010] 1. This utility model features equidistant grooves on the surface of a threaded rod for installing a rubber bag. A guide rod is installed inside the grooves to slidably connect to the threaded column. During the screw's inverted installation and rotation, when the threaded column contacts the internal threads of the plate, the threads on the column surface are opposite in direction to those on the rod surface. As the screw rotates, the threaded column moves upward, pressurizing the rubber bag and causing it to rupture. The adhesive inside flows out and fills the gap between the screw and the mounting plate. After the screw is installed and the adhesive dries, it reinforces the connection between the screw and the mounting plate, effectively preventing the screw from loosening and ensuring stability during installation and use.
[0011] 2. This utility model provides four equidistant slender bolts on the surface of the screw head. When the screw installation location is hard, or when it is necessary to ensure the screw is installed at a vertical angle, first tighten the four slender bolts to a certain depth on the installation surface. This helps to assist in the installation and guide the screw. Finally, tighten the four slender bolts to ensure the screw is installed smoothly and also to increase the screw's stability, thus ensuring the screw's stable use. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Example
[0018] Please see Figures 1-3The multi-functional linkage screw shown in the figure includes a screw head 1, a threaded rod 2, a reinforcing component and a limiting component. The reinforcing component is installed on the surface of the threaded rod 2, and the limiting component is installed on the surface of the screw head 1. During the installation process, the threaded rod 2 drives the reinforcing component to start and play a reinforcing role.
[0019] Based on the aforementioned solution, the reinforcement component includes a groove 3 and a plastic bag 4. The surface of the threaded rod 2 has four equally spaced grooves 3. The plastic bag 4 is installed on the inner wall of the four grooves 3 away from the screw head 1. The reinforcement component also includes a guide rod 5 and a threaded post 6. The guide rod 5 is fixedly connected inside each of the four grooves 3. The threaded post 6 is slidably connected to the surface of the guide rod 5. The thread on the surface of the threaded post 6 is opposite in direction to the thread on the surface of the threaded rod 2.
[0020] Furthermore, the outer wall of the threaded post 6 extends to the outside of the threaded rod 2;
[0021] Equidistant grooves 3 are made on the surface of the threaded rod 2 to install the plastic bag 4, and a guide rod 5 is set inside the groove 3 to slide and connect the threaded post 6. During the screw's inverted installation and rotation, when the threaded post 6 contacts the thread inside the plate, since the thread on the surface of the threaded post 6 is opposite in direction to the thread on the surface of the threaded rod 2, the screw rotation drives the threaded post 6 to move upward. As the screw rotation and installation proceed, the threaded post 6 moves upward and presses the plastic bag 4, causing the plastic bag 4 to rupture and the glue inside to flow out, filling the gap between the screw and the hanging plate. After the screw installation is completed and the glue dries, it plays a reinforcing role between the screw and the hanging plate, effectively preventing the screw from loosening, and thus ensuring the stability of the screw during installation and use.
[0022] As a further improvement of this invention, the limiting component includes slender bolts 8, and the top of the screw head 1 is threaded with four equidistant slender bolts 8.
[0023] Furthermore, both the slender bolt 8 and the screw head 1 have a slot 7 at their top;
[0024] Four slender bolts 8 are set at equal intervals on the surface of the screw head 1. When the screw installation location is hard, or when it is necessary to ensure that the screw is installed at a vertical angle, first tighten the four slender bolts 8 to a certain depth on the installation surface. This will help to install and guide the screw. Finally, tighten the four slender bolts 8 to ensure that the screw is installed smoothly and also to increase the stability of the screw, thus ensuring the stable use of the screw.
[0025] It should be noted that this utility model is a multi-functional linkage screw. First, align the threaded rod 2 of the screw with the installation position. Then, rotate the four slender screws 8 to a certain depth in the installation position, which assists in the installation and provides guidance. Next, rotate the screw for installation. As the screw is installed, the threaded post 6 inside the groove 3 on the surface of the threaded rod 2 comes into contact with the installation position. Since the thread on the surface of the threaded post 6 is opposite in direction to the thread on the surface of the threaded rod 2, the screw rotation drives the threaded post 6 to move upward. As the screw rotates and the installation progresses, the threaded post 6 moves upward and pressurizes the plastic bag 4, causing the plastic bag 4 to rupture and the glue inside to flow out and fill the gap between the screw and the hanging plate. After the screw is installed and the glue dries, it reinforces the connection between the screw and the hanging plate. Finally, tighten the four slender bolts 8 to ensure the screw is installed smoothly and to increase the stability of the screw, ensuring stable use.
