Description

Technical Field

[0001] The utility model belongs to the technical field of hexagonal bolts, in particular to a hexagonal head bolt which is not easily corroded. Background Art

[0002] As a standard part, hexagon head bolts are widely used in electromechanical products. Their main function is to connect two parts.

[0003] For example, the Chinese patent with publication number CN202531606U provides a hexagonal head bolt that is not easily corroded according to the utility model, including a screw rod and a hexagonal bolt head connected to the screw rod, the hexagonal bolt head having six identical tightening surfaces, and two through holes penetrating the hexagonal bolt head on two adjacent tightening surfaces.

[0004] This patent has some disadvantages when used, such as: the main function of this utility model is that the hexagonal head bolt of the utility model can be used to fix the bolt through the double hole to prevent the bolt from loosening, easy to position and easy to operate. If it is operated in the air, the fixation is stronger. However, since the nut on the upper end of the bolt is exposed to the outside for a long time, during the long-term use, although it can play a good role in firmness and stability, after a long period of rain erosion, the nut will rust and soften, resulting in the bolt being broken when it is removed. Due to long-term erosion, the hardness of the bolt will decrease, the bolt will fall off, causing the two connected parts to be disconnected, and unnecessary work accidents will occur, causing unimaginable property losses and even personal injuries.

[0005] In view of this, we propose a hexagonal head bolt which is not easily corroded. Utility Model Content

[0006] The purpose of the utility model is to provide a hexagonal head bolt that is not easily corroded in order to solve the above-mentioned technical problems. The first shell and the second shell are connected and combined to seal the nut exposed to the outside inside, so as to form a closed structure to ensure that the nut will not be corroded and avoid work accidents.

[0007] In view of this, a hexagonal head bolt that is not easily corroded includes a first shell, a second shell and a nut. A mounting block is fixedly installed on the upper end of the first shell, a fixing rod is inserted into the interior of the mounting block, a supporting rod is rotatably installed on the surface of the fixing rod, and a sealing cover plate is fixedly installed on one end of the supporting rod.

[0008] Based on the above structure, before the bolt is installed, the first shell and the second shell are installed on the outer surface of the nut, which can well protect the nut from corrosion. Because of the presence of the support rod, it can be rotated on the surface of the fixed rod, so that the sealing cover can be opened upward or downward. The presence of the sealing cover can seal and cover a 360° circular hole formed at the upper end of the first shell and the second shell after the installation is completed, so as to better realize a complete sealing structure. When the operator needs to remove the bolt, the sealing cover can be opened to rotate and remove the nut inside it, so that the bolt is separated from the parts as a whole, which not only enhances the overall corrosion resistance of the bolt, but also facilitates the operator to remove the bolt.

[0009] Preferably, a fixing ring is fixedly mounted on the upper surface of the main body, a mounting ring is detachably mounted on the upper surface of the fixing ring, and a fiber cylinder cover is fixedly mounted on one side surface of the mounting ring.

[0010] Furthermore, a first fan-shaped hole is arranged on the upper and lower surfaces of the first shell, which can form a 360° circular hole with the second fan-shaped hole opened on the second shell, thereby facilitating the operator to observe the internal nut and remove the bolts. The first mounting hole can form a circular hole with the second mounting hole, and the first shell can be installed on the outer surface of the nut through a threaded connection to seal and protect the nut.

[0011] Preferably, a first connection hole is formed on one side surface of the first shell, and a first limiting block is fixedly installed inside the first shell.

[0012] Furthermore, due to the presence of the first limit block, when the first shell and the second shell are installed on the outer surface of the nut, the nut can be prevented from deviating from its position after long-term use. The presence of the first limit block can fix the position of the nut, and the presence of the first connecting hole can reinforce the installation of the first shell, so that the first shell will not fall off after long-term use.

[0013] Preferably, the upper and lower surfaces of the second shell are both provided with second fan-shaped holes, and the one side surface of the second shell is provided with a second mounting hole.

[0014] Furthermore, by opening a second fan-shaped hole on the upper and lower surfaces of the second shell, a 360° circular hole can be formed with the first fan-shaped hole, which is located directly above and below the nut, making it convenient for observation and removal. The second mounting hole can form a circular hole with the first mounting hole, and when the two shells are completely attached to the nut, the two shells can be reinforced and installed on the outer surface of the nut through a threaded connection.

[0015] Preferably, a second connection hole is formed on one side surface of the second shell, and a second limiting block is fixedly installed inside the second shell.

[0016] Furthermore, through the provision of a second connecting hole, the second shell can be installed on the outer surface of the nut by screwing the second shell into engagement with the threaded hole, thereby playing the role of reinforcing the installation of the second shell. Through the provision of a second limit block, when the first shell and the second shell are installed on the outer surface of the nut, the nut can be prevented from deviating from the position after long-term use. The presence of the second limit block can fix the position of the nut, and can form an all-round position fixation with the first limit block, thereby better realizing the reinforced and stable structure of the bolt.

[0017] Preferably, a plug-in rod is fixedly mounted on one side surface of the first shell, and a plug-in hole is opened on one side surface of the second shell.

[0018] Furthermore, by installing a plug-in rod on one side surface of the first shell, when the first shell and the second shell are combined and installed, the plug-in rod located on the surface of the first shell and the plug-in hole opened on the surface of the second shell form a plug-in structure, thereby better achieving the effect of reinforced installation of the two shells.

[0019] Preferably, a cross hole is provided on the upper surface of the nut, a plurality of threaded holes are provided on one side surface of the nut, and a threaded column is fixedly mounted on the lower surface of the nut.

[0020] Furthermore, by opening a cross hole on the upper surface of the nut, the cross hole is located directly below the hole formed by the first shell and the second shell, which makes it convenient for operators to remove the bolts neatly. Through the set threaded holes, the six sides of the nut can be fully fixed to the first shell and the second shell to prevent them from falling off after long-term use. The threaded column is located directly below the nut and is a threaded screwing column for connecting parts. The threaded column can be threadedly connected to the inside of the part by rotating the cross hole, or the threaded column can be removed from the part connection by rotating the cross hole.

[0021] The beneficial effects of the utility model are:

[0022] 1. The hexagonal head bolt which is not easy to be corroded, when the first shell and the second shell are installed on the outer surface of the nut before the bolt is installed, the nut can be well protected from corrosion, and because of the existence of the support rod, it can be rotated on the surface of the fixed rod, so that the sealing cover plate can be opened upward or downward, and the existence of the sealing cover plate can seal and cover a 360° circular hole formed at the upper end of the first shell and the second shell after the installation is completed, so as to better realize a complete sealing structure, and when the operator needs to remove the bolt, the nut inside the sealing cover plate can be rotated and removed by opening the sealing cover plate, so that the bolt is separated from the parts connection as a whole, which not only enhances the corrosion resistance of the bolt as a whole, but also facilitates the operator to remove the bolt.

[0023] 2. This hexagonal head bolt, which is not easily corroded, can connect the second shell to the outer surface of the nut by screwing the second shell into the threaded hole through the second connecting hole, thereby reinforcing the installation of the second shell. By setting the second limit block, when the first shell and the second shell are installed on the outer surface of the nut, the nut can be prevented from deviating from the position after long-term use. The existence of the second limit block can fix the position of the nut, and can form an all-round position fixation with the first limit block, thereby better realizing the reinforced and stable structure of the bolt.

[0030] The following is combined with Figure 1-Figure 4 This application is described in further detail.

[0031] In the present application, the terms "upper", "lower", "left", "right", "front", "back", "top", "bottom", "inside", "outside", "middle", "vertical", "water flow" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings. These terms are mainly used to better describe the present application and its embodiments, and are not used to limit the indicated devices, elements or components to have a specific orientation, or to be constructed and operated in a specific orientation.

[0032] The embodiment of the present application discloses a hexagonal head bolt that is not easily corroded, including a first shell 2, a second shell 1 and a nut 13. A mounting block 16 is fixedly installed on the upper end of the first shell 2, a fixing rod 17 is inserted into the interior of the mounting block 16, a support rod 18 is rotatably installed on the surface of the fixing rod 17, and a sealing cover plate 19 is fixedly installed on one end of the support rod 18.

[0033] In one embodiment, first fan-shaped holes 4 are formed on the upper and lower surfaces of the first housing 2 , and a first mounting hole 6 is formed on one side surface of the first housing 2 .

[0034] Specifically, the first shell 2 can provide a carrier for the mounting block 16, and the mounting block 16 can be inserted into the fixing rod 17. The fixing rod 17 can be used to rotate the support rod 18 on its surface. The support rod 18 can be used to fix the sealing cover plate 19. Before the bolt is installed, the first shell 2 and the second shell 1 are installed on the outer surface of the nut 13, which can well protect the nut 13 from corrosion. Because of the existence of the support rod 18, it can be rotated on the surface of the fixing rod 17, so that the sealing cover plate 19 can be opened upward or downward. The existence of the sealing cover plate 19 can seal and cover a 360° circular hole formed at the upper end of the first shell 2 and the second shell 1 after the installation is completed, so as to better realize a completely sealed structure. When the operator needs to remove the bolt, the nut 13 inside can be rotated and removed by opening the sealing cover plate 19, so that the bolt is separated from the part connection as a whole, which not only enhances the corrosion resistance of the bolt as a whole, but also facilitates the removal of the bolt by the operator.

[0035] In this embodiment, a first fan-shaped hole 4 is provided on the upper and lower surfaces of the first shell 2, which can form a 360° circular hole with the second fan-shaped hole 3 provided on the second shell 1, thereby facilitating the operator to observe the internal nut 13 and remove the bolts. The first mounting hole 6 can form a circular hole with the second mounting hole 5, so that the first shell 2 can be installed on the outer surface of the nut 13 through a threaded connection, thereby sealing and protecting the nut 13.

[0036] In one embodiment, a first connection hole 8 is formed on one side surface of the first housing 2 , and a first limiting block 11 is fixedly installed inside the first housing 2 .

[0037] Specifically, by opening the first connection hole 8 on one side surface of the first shell 2, the first shell 2 can be installed on one side surface of the nut 13 by screwing with the threaded hole 14, and the first limit block 11 can play a limiting role.

[0038] In this embodiment, due to the presence of the first limit block 11, when the first shell 2 and the second shell 1 are installed on the outer surface of the nut 13, the nut 13 is prevented from deviating from its position after long-term use. The presence of the first limit block 11 can fix the position of the nut 13. The presence of the first connecting hole 8 can reinforce the installation of the first shell 2 so that the first shell 2 will not fall off after long-term use.

[0039] In one embodiment, the second sector-shaped holes 3 are formed on the upper and lower surfaces of the second housing 1 , and a second mounting hole 5 is formed on one side surface of the second housing 1 .

[0040] In this embodiment, by opening a second fan-shaped hole 3 on the upper and lower surfaces of the second shell 1, a 360° circular hole can be formed with the first fan-shaped hole 4, which is located just above and just below the nut 13, so as to facilitate observation and removal. By setting a second mounting hole 5, a circular hole can be formed with the first mounting hole 6, and then when the two shells are completely attached to the nut 13, the two shells can be reinforced and installed on the outer surface of the nut 13 by screwing together.

[0041] In one embodiment, a second connection hole 7 is formed on one side surface of the second housing 1 , and a second limiting block 10 is fixedly installed inside the second housing 1 .

[0042] In this embodiment, by setting the second connecting hole 7, the second shell 1 can be installed on the outer surface of the nut 13 by screwing the second shell 1 with the threaded hole 14, so as to reinforce the installation of the second shell 1. By setting the second limit block 10, when the first shell 2 and the second shell 1 are installed on the outer surface of the nut 13, the nut 13 is prevented from deviating from the position after long-term use. The existence of the second limit block 10 can fix the position of the nut 13, and can form an all-round position fixation with the first limit block 11, so as to better realize the reinforced and stable structure of the bolt.

[0043] In one embodiment, a plug-in rod 9 is fixedly mounted on one side surface of the first housing 2 , and a plug-in hole 20 is opened on one side surface of the second housing 1 .

[0044] In this embodiment, by installing a plug-in rod 9 on one side surface of the first shell 2, when the first shell 2 and the second shell 1 are combined and installed, the plug-in rod 9 located on the surface of the first shell 2 and the plug-in hole 20 opened on the surface of the second shell 1 form a plug-in structure, thereby better achieving the effect of reinforced installation of the two shells.

[0045] In one embodiment, a cross hole 12 is formed on the upper surface of the nut 13 , a plurality of threaded holes 14 are formed on one side surface of the nut 13 , and a threaded column 15 is fixedly mounted on the lower surface of the nut 13 .

[0046] In this embodiment, a cross hole 12 is opened on the upper surface of the nut 13, and the cross hole 12 is located directly below the hole formed by the first shell 2 and the second shell 1, so that the operator can easily remove the bolts neatly. The threaded hole 14 is set, so that the six sides of the nut 13 can be fixed to the first shell 2 and the second shell 1 in all directions to prevent them from falling off after long-term use. The threaded column 15 is located directly below the nut 13 and is a threaded screwing column for connecting parts. The threaded column 15 is threadedly screwed into the inside of the part by rotating the cross hole 12, or the threaded column 15 is removed from the part connection by rotating the cross hole 12.

[0047] When the hexagonal head bolt of the present embodiment, which is not easily corroded, is used, before the bolt is installed, the first shell 2 and the second shell 1 are installed on the outer surface of the nut 13, which can well protect the nut 13 from corrosion. Because of the existence of the support rod 18, it can be rotated on the surface of the fixing rod 17, so that the sealing cover plate 19 can be opened upward or downward. The existence of the sealing cover plate 19 can seal and cover a 360° circular hole formed at the upper end of the first shell 2 and the second shell 1 after the installation is completed, so as to better realize a complete sealing structure. When the operator needs to remove the bolt, the nut 13 inside it can be rotated and removed by opening the sealing cover plate 19, so that the bolt is separated from the parts connection as a whole, which not only enhances the corrosion resistance of the bolt as a whole, but also facilitates the operator to remove the bolt.
