Description

Technical Field

[0001] The utility model relates to the technical field of screws, in particular to a multi-head screw. Background Art

[0002] A multi-head screw is a special screw that has multiple screw heads and can be screwed into multiple holes at the same time. This design is very useful in certain application scenarios, such as when multiple parts need to be assembled or disassembled quickly. The design of a multi-head screw usually includes multiple screw heads, each of which has its own guide hole and threaded hole. This design allows the screw to automatically align with each hole when inserted, and the length of the screw can be adjusted as needed. For example, in some multi-head screw designs, there is a connecting rod at the bottom of each screw head, which can pass through the guide hole so that the screw can be adjusted in length as needed. Although multi-head screws are very useful in many ways, their design and manufacturing also face some challenges. For example, the head of the existing multi-head screw is fixedly connected to the screw rod and cannot be disassembled. If it needs to be removed from an object, a matching screwdriver is required. At the same time, the existing multi-head screws do not have a chip collection function. Utility Model Content

[0024] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0025] Example:

[0026] Please combine Figure 1-5 A multi-head screw of this embodiment includes a disassembly structure 1, a chip collecting structure 2 and a main body structure 3, wherein the chip collecting structure 2 is located at the bottom of the disassembly structure 1, and the main body structure 3 is located inside the disassembly structure 1;

[0027] The disassembly structure 1 includes a screw head 101 , a groove 102 is formed on the upper surface of the screw head 101 , a mounting groove 103 is formed on the lower surface of the screw head 101 , and an internal thread 104 is formed on the inner wall of the mounting groove 103 .

[0028] The screw head 101 is set to a circular structure, the groove 102 can be set to a cross-shaped structure, and the installation groove 103 is set to a circular structure. The screw head 101 is designed to be circular, the groove 102 is cross-shaped, and the installation groove 103 is also circular. This design is convenient for operation using tools and ensures good matching between the screw and the component to be installed. The inner wall of the installation groove 103 is provided with an internal thread 104, which is convenient for disassembly and installation of the screw head 101. This makes it convenient to use a matching screwdriver according to different screw heads 101.

[0029] The chip collecting structure 2 comprises a screw rod 201 , a thread 202 is fixedly connected to the outer wall of the screw rod 201 , a chip collecting groove 203 is provided between the threads 202 , and a tip 204 is fixedly connected to the bottom of the screw rod 201 .

[0030] The diameter of the screw 201 is smaller than the diameter of the screw head 101, and the chip collecting grooves 203 are provided in a plurality and are evenly distributed on the outer wall of the screw 201. The chip collecting grooves 203 help the screw to enter the material and collect the debris generated during the cutting process. At the same time, the chip collecting grooves 203 are evenly distributed on the outer wall of the screw 201, which helps to improve the chip collecting efficiency.

[0031] The main structure 3 includes a mounting rod 301 , and an outer wall of the mounting rod 301 is provided with an external thread 302 .

[0032] The diameter of the mounting rod 301 matches the diameter of the mounting groove 103, and the mounting rod 301 is arranged on the top of the screw rod 201, and the mounting rod 301 is connected to the internal thread 104 inside the mounting groove 103 through the external thread 302. The mounting rod 301 is threadedly connected to the inside of the mounting groove 103 through the external thread 302, which ensures the installation and removal of the screw head 101.

[0033] The implementation principle of a multi-head screw in the embodiment of the present application is: according to the different models of the screw head 101, use a suitable tool such as a screwdriver to insert the groove 102 on the screw head 101 and start rotating the screw. As the screw rotates, the tip 204 of the screw first cuts into the material, and then the thread 202 on the screw rod 201 begins to engage with the material, allowing the screw to gradually go deeper. In this process, the chip collecting groove 203 serves to collect metal chips, prevent debris from scattering, and keep the working area clean. When the screw reaches the required depth, it stops rotating. At this time, the mounting rod 301 is tightly connected to the internal thread 104 in the mounting groove 103 through the external thread 302, ensuring that the screw head 101 and the screw rod 201 are a disassembly structure, which is convenient for operation using different tools.

[0034] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
