Description

Technical Field

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

[0002] Screws are tools that use the physical and mathematical principles of the circular rotation of an object's inclined surface and friction to gradually fasten objects and parts. Screws are a common term for fasteners and a daily colloquial term. Screws are an indispensable industrial necessity in daily life.

[0003] After searching, a Chinese patent discloses a screw (publication number CN215762709U). Although this patented technology improves the connection reliability of the screw and ensures that the screw is not easy to fail, it cannot prevent the screw from oxidation and rust. In particular, screws used outdoors or in environments with high humidity are easily exposed to water and air, which leads to accelerated oxidation and rust, resulting in thread slippage, making it difficult to disassemble the fastened objects, and even causing the screw to break due to rust, causing the fastened objects to separate and fall, which may cause safety hazards. Therefore, a technician in this field provides a screw to solve the problems raised in the above background technology. Utility Model Content

[0004] In order to make up for the above deficiencies, the utility model provides a screw, aiming to improve the problem that the screws in the comparative literature cannot prevent oxidation and rust, which may make the fastened objects difficult to disassemble, or even cause the screws to break due to rust, thereby causing the fastened objects to separate, posing a safety hazard.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A screw, comprising a hexagonal head, a stud fixedly connected to the bottom of the hexagonal head, an oil storage tank provided inside the stud, an oil filling hole provided inside the top of the stud, a rubber block fixedly connected to the bottom of the stud, a plurality of oil outlet holes provided inside the stud, a rubber ring sleeved on the top of the stud, and a water accumulation prevention mechanism provided on the top of the hexagonal head;

[0007] Through the above technical scheme, it is achieved that lubricating oil is injected into the oil storage tank through the oil filling hole, and can overflow through the oil outlet hole, so that a layer of oil film can be applied to the outside of the screw when the screw is screwed in, and the stud is isolated from the air because of the cooperation of the rubber block and the rubber ring and because it is inside the screw hole, so that it can prevent the screw from rusting.

[0008] Furthermore, the hexagonal head has an inner hexagonal groove, the hexagonal head has a cross groove, and the top of the hexagonal head has two opposite sides with transverse grooves.

[0009] Through the above technical solution, it is possible to use a variety of tools to install and remove screws through the hexagonal socket, cross slot, transverse slot and the hexagonal head itself, so that disassembly can be carried out even when the tools are not complete, and the problem of difficulty in removing screws due to thread slippage of the hexagonal head can be prevented.

[0010] Further, the anti-water accumulation mechanism includes a plug block, the plug block is arranged inside the hexagonal groove, the top of the plug block is fixedly connected to a cover cap, the bottom of the cover cap is fixedly connected to horizontal plugs on both opposite sides, the top of the cover cap is fixedly connected to an anti-lost rope, and the other end of the anti-lost rope is fixedly connected to the outside of the rubber ring;

[0011] Through the above technical solution, the hexagonal groove is blocked by a plug, and the transverse groove is blocked by a plug, so that water can be prevented from entering the interior of the hexagonal head, thereby preventing the interior of the hexagonal head from rusting.

[0012] Furthermore, the oil outlet holes are connected to the oil storage tank, and the oil outlet holes are distributed on the stud in a spiral shape;

[0013] Through the above technical solution, by utilizing the connection between the oil outlet hole and the oil storage tank, the lubricating oil inside the oil storage tank can be discharged through the oil outlet hole, and because the oil outlet holes are spirally distributed on the stud, the lubricating oil can be distributed more evenly when the stud is twisted.

[0014] Furthermore, the inner hole diameter of the rubber ring is slightly smaller than the diameter of the stud, and the bottom of the rubber block is a curved surface;

[0015] Through the above technical solution, the rubber ring is made of elastic material, and the inner hole diameter of the rubber ring is slightly smaller than the diameter of the stud, so that the rubber ring can be tightly wrapped around the outside of the stud. Since the bottom of the rubber block is a curved surface, the rubber block can be easily inserted into the screw hole.

[0016] Further, the hexagonal socket is connected to the cross socket;

[0017] According to the technical solution, since the hexagon socket and the cross socket are connected, the cross socket can be used for disassembly when the screw is not disassembled by using the hexagon socket.

[0018] Further, the cross section of the plug block is hexagonal, and the cross plug is a rectangular parallelepiped;

[0019] According to the technical solution, since the plug block is hexagonal and the transverse plug is a rectangular parallelepiped, the plug block can be inserted into the inner hexagonal groove and the transverse plug can be inserted into the interior of the transverse groove.

[0020] Furthermore, the top of the cap is a curved surface, and the radius of the anti-water accumulation mechanism is greater than the diameter of the hexagonal head;

[0021] Through the above technical solution, the curved surface of the cap can be used to prevent water droplets from gathering at the cap, and since the radius of the anti-water accumulation mechanism is greater than the diameter of the hexagonal head, the top of the hexagonal head can be completely covered.

[0022] The utility model has the following beneficial effects:

[0023] 1. In the utility model, the screw is isolated from the air by the composition of the oil storage tank, the oil filling hole, the rubber block, the oil outlet hole, the rubber ring and the like. At the same time, a layer of oil film can be coated on the surface of the screw by the lubricating oil to prevent the screw from rusting. Therefore, the phenomenon of screw thread slipping due to rusting can be prevented, and the difficulty of disassembly of the fastened object caused by thread slipping can be avoided. At the same time, the screw breakage due to rusting can be avoided, and the separation of the fastened object can be avoided, thereby increasing safety.

[0024] 2. In the utility model, by means of the composition of the hexagonal head, the hexagonal socket, the cross slot and the transverse slot, the workers can use a variety of tools to remove the screws, so when the tools are incomplete, other tools can be used for removal.

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Reference Figure 1-2 , the utility model provides an embodiment: a screw, including a hexagonal head 1, a stud 2 is fixedly connected to the bottom of the hexagonal head 1, an oil storage tank 3 is opened inside the stud 2, an oil filling hole 4 is opened inside the top of the stud 2, a rubber block 5 is fixedly connected to the bottom of the stud 2, a plurality of oil outlet holes 6 are opened inside the stud 2, a rubber ring 7 is sleeved on the top of the outer top of the stud 2, an anti-water accumulation mechanism 8 is arranged on the top of the hexagonal head 1, the oil outlet hole 6 is connected to the oil storage tank 3, the oil outlet holes 6 are spirally distributed on the stud 2, the inner hole diameter of the rubber ring 7 is slightly smaller than the diameter of the stud 2, and the bottom of the rubber block 5 is a curved surface;

[0033] Specifically, the hexagonal head 1 can be used to facilitate the disassembly of the screw, the oil storage tank 3 can store lubricating oil, the oil filling hole 4 can conveniently inject lubricating oil into the oil storage tank 3, the outlet of the screw hole can be blocked by the rubber block 5, the inlet of the screw hole can be blocked by the rubber ring 7, and the stability of the screw can also be increased, and the lubricating oil can overflow through the oil outlet 6, and the lubricating oil can be applied to the screw hole and the outside of the stud 2 when screwing in, and the lubricating oil in the oil storage tank 3 can seep out through the oil outlet 6, thereby playing a role in preventing oxidation and rust.

[0034] Reference Figure 3 The hexagonal head 1 has an inner hexagonal groove 9, the inner hexagonal groove 10, and the top of the hexagonal head 1 has two opposite sides with transverse grooves 11, and the inner hexagonal groove 9 is connected with the cross groove 10;

[0035] Specifically, the hexagonal socket 9 can be used to remove the screw using a hexagonal wrench, and the cross slot 10 can be used to remove the screw using a cross screwdriver. At the same time, the cross slot 10 can be used to remove the screw using a flat-blade screwdriver due to the long slot, and the transverse slot 11 can be used to remove the screw using a flat-blade screwdriver with a wider blade, and the hexagonal head 1 can be used to remove the screw using a wrench.

[0036] Reference Figure 4The anti-water accumulation mechanism 8 includes a plug block 801, which is arranged inside the hexagonal groove 9, a cap 802 is fixedly connected to the top of the plug block 801, and the bottom of the cap 802 is fixedly connected to the opposite sides with a transverse plug 803, and the top of the cap 802 is fixedly connected to an anti-lost rope 804, and the other end of the anti-lost rope 804 is fixedly connected to the outside of the rubber ring 7. The cross section of the plug block 801 is hexagonal, the transverse plug 803 is a rectangular parallelepiped, and the top of the cap 802 is a curved surface. The radius of the anti-water accumulation mechanism 8 is greater than the diameter of the hexagonal head 1;

[0037] Specifically, the anti-water accumulation mechanism 8 is made of rubber-like materials as a whole. Since the cross-section of the plug 801 is hexagonal, the plug 801 can be inserted into the interior of the hexagonal groove 9, and the cap 802 can cover the hexagonal head 1. Since the radius of the anti-water accumulation mechanism 8 is greater than the diameter of the hexagonal head 1, it can completely cover the top of the hexagonal head 1. At the same time, since the top of the anti-water accumulation mechanism 8 is a curved surface, it is difficult for water stains to adhere to the top of the anti-water accumulation mechanism 8, thereby preventing rainwater from staying on the hexagonal head 1 for a long time and avoiding rusting of the hexagonal head 1. Since the horizontal plug 803 is a rectangular parallelepiped, it is similar in shape to the horizontal groove 11, thereby blocking the horizontal groove 11, and further preventing water stains from flowing into the interior of the hexagonal groove 9 and causing rusting inside the hexagonal head 1, and can be connected to the rubber ring 7 using an anti-loss rope 804 to prevent the anti-water accumulation mechanism 8 from being lost.

[0038] Working principle: When screwing a screw into an object, first insert the rubber block 5 into the screw hole, then push the rubber ring 7 in the direction away from the hexagonal head 1, and then the oil filling hole 4 can be exposed, and lubricating oil is injected into the inside of the oil filling hole 4. When the lubricating oil overflows from the oil outlet hole 6 close to the hexagonal head 1, the stud 2 is screwed into the screw hole, so that the lubricating oil overflowing from the oil outlet hole 6 can be applied to the screw hole and the outside of the stud 2. When the stud 2 is screwed into the screw hole, since the rubber block 5 is made of rubber, it can use its own elasticity The screw hole is sealed, and after tightening, the rubber ring 7 is also blocked at the screw hole, thereby preventing air from entering the inside of the screw hole, thereby preventing oxidation and rusting. At the same time, the rubber ring 7 can be used to improve the stability of the screw. In addition, since the hexagonal slot 9, the cross slot 10, the transverse slot 11 and the hexagonal head 1 are provided, four tools can be used for disassembly, thereby preventing the lack of suitable tools for disassembly when the tools are incomplete. At the same time, if there is a phenomenon of thread slippage, other tools can also be used for disassembly.
