Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of fasteners, and in particular relates to a high-stability hexagon socket screw. Background Art
[0002] Screws, as key components for connecting and securing objects, are widely used in a variety of fields, including machinery, construction, and electronics. Hexagon socket screws, with their unique hexagonal socket design, provide a more stable and precise tightening effect, making them highly popular among users.
[0003] Existing hexagon socket screws typically consist of a stud, a nut, and a hexagon socket. The stud penetrates the object being connected, the nut provides a tightening point, and the hexagon socket allows for precise tightening or loosening with an hexagonal wrench. However, while existing hexagon socket screws generally meet practical requirements, they still have some significant shortcomings in practical applications.
[0004] First, existing structures often lack effective solutions to the problem of screws being difficult to disassemble after rusting. Once the screws rust due to long-term use or environmental factors, the disassembly process will become extremely difficult and may even damage the connected objects.
[0005] Secondly, existing hexagon socket screws also have certain hidden dangers in terms of safety. Outsiders may remove the screws by simply twisting the nuts, thereby threatening the safety of equipment or structures.
[0006] Finally, the stability of existing hexagon socket screws needs to be improved, especially in environments with large vibrations. The screws may gradually loosen due to vibrations, thereby affecting their connection and fixation effects.
[0007] Therefore, it is very necessary to invent a high-stability hexagon socket screw. Utility Model Content
[0008] The purpose of the utility model is to provide a high-stability hexagon socket screw to solve the problems mentioned in the background technology.
[0009] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:
[0010] The utility model discloses a high-stability hexagon socket screw, comprising a stud, a nut, a hexagon socket, a sleeve, a locking column, a reinforcement frame and an oil filling groove, wherein the upper end of the stud is fixed with the nut by welding, wherein the other end of the nut is provided with a hexagon socket; the outer side surface of the nut is rotatably mounted with a sleeve, wherein at least one locking column is slidably mounted inside the nut and the sleeve; the lower end of the nut is fixed with the reinforcement frame by welding, and the inside of the nut and the stud is provided with an oil filling groove running through.
[0011] Furthermore, the oil filling groove is respectively communicated with the inner hexagonal groove and the outer side surface of the stud, and a guide rope is movably provided inside the oil filling groove; the two ends of the guide rope are respectively fixed to the inner wall of the oil filling groove. Such a setting makes it easy to add lubricating oil to the intersection of the stud and the nut.
[0012] Furthermore, the locking column includes a bent tube and tape. The bent tube is U-shaped, and nuts and sleeves are slid through both ends of the bent tube; the outer sides of both ends of the bent tube are wrapped and fixed with tape. This arrangement can prevent outsiders from removing the screws by twisting the sleeve.
[0013] Furthermore, the reinforcement frame includes a reinforcement plate, a protrusion and a connecting plate. The reinforcement plate is arranged on the outside of the stud, and a number of protrusions are evenly distributed on the lower side of the reinforcement plate; the upper side of the reinforcement plate is fixed with a connecting plate by welding, wherein a number of deformation grooves are opened inside the connecting plate. Such an arrangement can avoid the loosening of the screws due to vibration and other reasons, thereby improving the stability of the screws.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] 1. The oil filling groove of this utility model allows the user to simply drip lubricant into the hexagonal socket and use a small object such as an embroidery needle or toothpick to move the guide rope. This allows the lubricant to smoothly flow through the oil filling groove and reach the intersection of the stud and nut for effective lubrication. This design not only simplifies the lubrication process but also improves lubrication accuracy and efficiency.
[0016] 2. The locking column of the utility model is set up. When in use, the elbow can combine the nut and the sleeve together. After the screw is installed, the tape on the elbow can be removed, and then the elbow can be slid out in the nut and the sleeve, thereby preventing outsiders from removing the screw by twisting the sleeve. When the staff needs to remove the screw by twisting the sleeve, they only need to insert the elbow into the nut and the sleeve again.
[0017] 3. The reinforcement frame of this utility model ensures that as the screws are tightened, the reinforcement plate comes into close contact with the object being fixed, while the connecting plate deforms accordingly with the tightening force. This design not only ensures the tightening effect of the screws, but also increases the friction between the nut and the object being fixed through the tension of the connecting plate and the cooperation of the bumps with the reinforcement plate, thus effectively preventing the screws from loosening due to vibration and other factors.

[0027] See also Figures 1 to 4As shown, the utility model is a high-stability hexagon socket screw, comprising a stud 1, a nut 2, a hexagon socket 3, a sleeve 4, a locking column 5, a reinforcement frame 6 and an oil filling groove 7. The upper end of the stud 1 is fixed with the nut 2 by welding, wherein the other end of the nut 2 is provided with a hexagon socket 3; the outer side of the nut 2 is rotatably mounted with a sleeve 4, wherein at least one locking column 5 is slidably mounted inside the nut 2 and the sleeve 4; the lower end of the nut 2 is fixed with a reinforcement frame 6 by welding, and an oil filling groove 7 is provided through the inside of the nut 2 and the stud 1.
[0028] Specifically, the oil filling groove 7 is respectively communicated with the inner hexagonal groove 3 and the outer side surface of the stud 1, and a guide rope 8 is movably provided inside the oil filling groove 7; the two ends of the guide rope 8 are respectively fixed to the inner wall of the oil filling groove 7. During use, if the stud 1 is locked inside the nut due to rust, lubricating oil can be dripped into the oil filling groove 7 at the position of the inner hexagonal groove 3, and then the guide rope 8 can be picked up by a thinner object such as an embroidery needle or a toothpick, so that the lubricating oil passes through the oil filling groove 7 and enters the intersection of the stud 1 and the nut, thereby lubricating the stud 1 and the nut.
[0029] Specifically, the locking column 5 includes a bent tube 51 and a tape 52. The bent tube 51 is in a "U" shape, and both ends of the bent tube 51 are slid through with a nut 2 and a sleeve 4; the outer sides of both ends of the bent tube 51 are wrapped and fixed with tape 52. When in use, the bent tube can combine the nut 2 and the sleeve 4 together. After the screw is installed, the tape 52 can be removed from the bent tube 51, and then the bent tube 51 can be slid out in the nut 2 and the sleeve 4, thereby preventing outsiders from removing the screw by twisting the sleeve 4. When the staff needs to remove the screw by twisting the sleeve 4, they only need to insert the bent tube 51 into the nut 2 and the sleeve 4 again.
[0030] Specifically, the reinforcement frame 6 includes a reinforcement plate 61, a protrusion 62 and a connecting plate 63. The reinforcement plate 61 is arranged on the outside of the stud 1, and a number of protrusions 62 are evenly distributed on the lower side of the reinforcement plate 61; the upper side of the reinforcement plate 61 is fixed with a connecting plate 63 by welding, wherein a number of deformation grooves are opened inside the connecting plate 63. When in use, as the screws are gradually tightened, the reinforcement plate 61 can be connected with the fixed object accordingly, and then as the screws are tightened again, the connecting plate 63 can be deformed accordingly until the screws can no longer be tightened. At this time, through the tension of the connecting plate 63 and the cooperation of the protrusion 62 and the reinforcement plate 61, the friction between the nut 2 and the fixed object can be increased, thereby avoiding the loosening of the screw due to vibration and other reasons, and improving the stability of the screw.
[0031] See also Figure 1-4As shown, the utility model is a high-stability hexagonal screw, and its working principle is: when in use, the screw can be tightened by cooperating with the hexagonal tool and the hexagonal slot 3 or twisting the sleeve 4, wherein after the tightening is completed, the locking column 5 can be removed from the inside of the nut 2 and the sleeve 4, so as to prevent other people from loosening the device by twisting the sleeve 4, and the reinforcing frame 6 can improve the stability of the screw. When the screw needs to be removed, the screw can be removed by cooperating with the hexagonal tool and the hexagonal slot 3, or the locking column 5 can be inserted into the inside of the nut 2 and the sleeve 4, and then the sleeve 4 is twisted to remove the screw, wherein, the lubricating oil can be added to the intersection of the stud 1 and the nut by cooperating with the oil filling groove 7 and the guide rope 8.
