Description

Technical Field

[0001] The utility model relates to the technical field of bolts, in particular to a double hexagon bolt. Background Technique

[0002] Bolts are also known as screw parts, screws, bolt nails, standard parts, fasteners, etc. When installing items, bolts are needed for installation operations to ensure the stability of the installation position of the installed items. With the good pressure resistance of bolts, it is convenient to fix different items or materials. In daily use, a double hexagon bolt is needed for installation operations. Among them, the "double hexagon bolt" disclosed in the publication number "CN217653051U" has solved various drawbacks that if dust in the installation hole is not cleaned in time during installation, it is likely to affect the fastening performance of the bolt during installation. After further retrieval, it is found that the "double hexagon bolt head bolt" disclosed in the publication number "CN215487152U" has effectively solved the technical drawbacks that after the bolt head is corroded, the surface will rust and fall off, thus affecting the overall strength of the bolt, and at the same time, it will also affect the replacement of the bolts of the entire object in the later stage. However, bolts with similar structures still have many defects in actual use. For example, they do not have the function of automatic lubrication. After long-term use of the bolts, problems such as screwing jams are likely to occur, resulting in the inability to reuse the bolts, reducing the utilization rate of the bolts, increasing the economic expenditure for installation operations using bolts. At the same time, they do not have the function of anti-dropping. When the bolt is subjected to external force, the hexagon nut is likely to vibrate and fall off the installation position, reducing the reliability of using the bolt and also reducing the stable effect of installing items with the bolt. Therefore, a double hexagon bolt needs to be designed. Content of the Utility Model

[0003] The purpose of the utility model is to provide a double hexagon bolt to solve the problems put forward in the above background technique.

[0004] To achieve the above purpose, the utility model provides the following technical solution: A double hexagon bolt, including a screw rod, a pressing mechanism and an anti-dropping mechanism. A hexagon nut is fixedly installed at the top of the screw rod. A pressing mechanism is movably installed inside the hexagon nut. The pressing mechanism includes a support rod. A return spring is sleeved outside the support rod. One end of the support rod is fixedly installed with a linkage rod. A valve plate is fixedly installed at the bottom end of the linkage rod. A screw sleeve is threadedly installed outside the screw rod. Two groups of anti-dropping mechanisms are movably installed outside the screw sleeve. The anti-dropping mechanism includes a first moving arm. A pin seat is fixedly installed at the bottom end of the first moving arm. A second moving arm is movably installed on one side of the screw sleeve through a bolt. A locking seat is fixedly installed at the bottom end of the second moving arm.

[0005] By pressing the support rod, the linkage rod can be driven by the return spring to move horizontally. The horizontally moving linkage rod can drive the valve plate to move horizontally, so that the lubricating oil stored inside the hexagonal nut is transported to the surface of the screw through the conveying groove, realizing the function of automatically lubricating the screw, solving the problem that the screw is prone to jamming after long-term use, facilitating the secondary use of the bolt, improving the utilization rate of the screw, and reducing the economic expenditure for installation operations using the screw; when the nut sleeve moves to the specified position, by manually moving the second moving arm and the first moving arm by the operator, the locking seat and the pin seat can be driven to move arcuately to both sides of the screw with the bolt as the axis, and then by rotating the locking piece, the pin seat can be fixed inside the locking seat, realizing the function of assisting in fixing the nut sleeve, avoiding the self-position movement of the nut sleeve due to the vibration force, realizing the function of preventing the nut sleeve from falling off, solving the problem that the nut sleeve vibrates and falls off the installation position due to external force on the screw, increasing the reliability of using the bolt, and also improving the stable effect of installing items using the bolt.

[0006] Preferably, a lubricating oil filling port is provided on one side of the top of the hexagonal nut, and a lid is threadedly installed on the top of the filling port. Through the filling port, it is convenient to replenish the lubricating oil inside the hexagonal nut, and the cooperation of the lid and the hexagonal nut can ensure the airtight effect of the internal storage space of the hexagonal nut.

[0007] Preferably, a gasket is fixedly installed on the top of the hexagonal nut, and a hexagonal groove is provided inside the gasket. The gasket can facilitate the screwing of the hexagonal nut, and at the same time, the special cross structure of the hexagonal groove can facilitate the use of corresponding tools for the screwing and installation operation of the hexagonal nut.

[0008] Preferably, a button is fixedly installed at one end of the support rod, and a conveying groove is provided at the bottom inside the hexagonal nut. The button can prevent the hard support rod from directly contacting the operator's palm, and at the same time, the soft rubber material of the button can improve the operator's usage experience.

[0009] Preferably, a copper sheet is fixedly installed on the inner side of the nut sleeve, and a tungsten steel sheet is fixedly installed on the inner side of the copper sheet. The high thermal conductivity of the copper sheet can prevent the deformation of the nut sleeve caused by the high temperature generated during the screwing of the nut sleeve, and the high hardness of the tungsten steel sheet can increase the overall hardness of the nut sleeve.

[0010] Preferably, a locking piece is threadedly installed on the front of the locking seat, and one end of the locking piece extends into the pin seat. By manually rotating the locking piece, one end of the locking piece can extend into the locking seat to abut against one side of the pin seat, realizing the function of locking the moving position of the pin seat and avoiding the separation of the pin seat and the locking seat from the installation position due to external impact on the device.

[0019] The following further describes the technical solutions of the present utility model with reference to the accompanying drawings and specific embodiments.

[0020] Embodiment 1

[0021] As Figure 1 、 Figure 2 、Figure 3 , Figure 4 As shown in Figure 4 , a double hexagon bolt proposed by the present utility model includes a screw rod 1, a pressing mechanism 3 and an anti-dropping mechanism 5. A hexagon nut 101 is fixedly installed at the top of the screw rod 1. A gasket 2 is fixedly installed at the top of the hexagon nut 101. A hexagon groove 201 is formed inside the gasket 2. A pressing mechanism 3 is movably installed inside the hexagon nut 101. The pressing mechanism 3 includes a support rod 301;

[0022] A return spring 302 is sleeved outside the support rod 301. One end of the support rod 301 is fixedly installed with a linkage rod 303. A valve plate 304 is fixedly installed at the bottom end of the linkage rod 303. A screw sleeve 4 is threadedly installed outside the screw rod 1. A copper sheet 401 is fixedly installed inside the screw sleeve 4. A tungsten steel sheet 402 is fixedly installed inside the copper sheet 401. Two groups of anti-dropping mechanisms 5 are movably installed outside the screw sleeve 4;

[0023] The anti-dropping mechanism 5 includes a first moving arm 501. A pin seat 502 is fixedly installed at the bottom end of the first moving arm 501. A second moving arm 503 is movably installed on one side of the screw sleeve 4 through a bolt. A locking seat 504 is fixedly installed at the bottom end of the second moving arm 503. A locking member 6 is threadedly installed on the front surface of the locking seat 504. One end of the locking member 6 extends into the pin seat 502.

[0024] The working principle of the double hexagon bolt based on Embodiment 1 is as follows: The function of the double hexagon bolt is realized by the cooperation of the hexagon nut 101 and the hexagon groove 201, which is convenient for subsequent installation operations using special tools. After moving the screw rod 1 to the specified installation position, and by using a tool to engage and twist the hexagon groove 201, the screw rod 1 is installed at the specified installation position. Then, by pressing the support rod 301, the linkage rod 303 can be driven to move horizontally by the return spring 302. The valve plate 304 can be driven to move horizontally by the horizontally moving linkage rod 303, so that the lubricating oil stored inside the hexagon nut 101 is transported to the surface of the screw rod 1 through the conveying groove 305;

[0025] The high elastic force of the return spring 302 can drive the linkage rod 303 to move horizontally in the reverse direction, so that the valve plate 304 moves horizontally to the top of the conveying groove 305 to close, thus completing the automatic lubrication operation of the screw rod 1, realizing the function of automatically lubricating the screw rod 1, facilitating the secondary use of the bolt, and improving the utilization rate of the screw rod 1;

[0026] Then, by screwing the screw sleeve 4, the position of the item to be installed can be locked. The high thermal conductivity of the copper sheet 401 can prevent the screw sleeve 4 from deforming due to the high temperature generated when screwing the screw sleeve 4. When the screw sleeve 4 moves to the specified position, the operator manually moves the second moving arm 503 to drive the locking seat 504 to move in an arc around the bolt to one side of the screw rod 1;

[0027] Then, the operator manually moves the first moving arm 501, causing the first moving arm 501 to drive the pin seat 502 to perform an arc-shaped position movement around the shaft bolt to the other side of the screw rod 1, so that one end of the pin seat 502 extends into the locking seat 504. Then, by rotating the locking member 6, the pin seat 502 can be fixed inside the locking seat 504, realizing the function of assisting in fixing the sleeve 4, avoiding the self-position movement of the sleeve 4 due to vibration force, and realizing the function of preventing the sleeve 4 from falling off.

One end of the support rod 301 is fixedly installed with a button 306, and a conveying groove 305 is opened at the bottom inside the hexagon nut 101.

[0030] In this embodiment, as Figure 1 、 Figure 2 shown, the lubricating oil inside the hexagon nut 101 can be conveniently replenished through the oil injection port 102, and the sealing effect of the storage space inside the hexagon nut 101 can be ensured by the cooperation of the lid and the hexagon nut 101;

[0031] As Figure 4 shown, the hard support rod 301 can be prevented from directly contacting the operator's palm through the button 306, and at the same time, the soft rubber material of the button 306 can improve the operator's use experience.
