[0003] Bolts and nuts are one of the fasteners among industrial equipment parts. The two can contact and tighten the object to be fastened from both sides. When used in mechanical operating equipment or transportation vehicles, the bolts and nuts will be subjected to continuous vibration due to the operation of the machinery.

Some existing technologies do not have a design to strengthen the connection strength between bolts and nuts, so that operators need to check regularly after long-term use. Nuts or bolts may also fall off, affecting the later use of the clamped object. The inspection process is also time-consuming and labor-intensive.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] like Figures 1 to 8As shown, the present invention provides a high-strength aluminum alloy structure for a fastener, including a positioning bolt 1, the inner wall of the positioning bolt 1 is provided with a limiting mechanism 3, the outer wall of the positioning bolt 1 is provided with a through groove 4, and the outer wall of the positioning bolt 1 is provided with a reinforcing mechanism 2; the reinforcing mechanism 2 includes a nut 201, the inner wall of the nut 201 is provided with an internal thread 202, the inner wall of the nut 201 is rotatably connected with a rotating plate 203, the outer wall of the rotating plate 203 is provided with an arc groove 204, the inner wall of the arc groove 204 is slidably connected with a round rod 205, the outer wall of the round rod 205 is fixedly connected with a rubber clamping block 206, the inner wall of the nut 201 is provided with a positioning groove 207, the outer wall of the rotating plate 203 is fixedly connected with a fixed block 208, the inner wall of the fixed block 208 is elastically connected with a clamping block 210 through a connecting spring 209, and the inner wall of the nut 201 is provided with a clamping groove 211.

[0030] The above scheme is adopted: the positioning bolt 1 and the nut 201 together constitute the main body of the aluminum alloy fastener, the positioning bolt 1 can be screwed through the threaded hole of the object to be fastened, and the nut 201 is screwed under the positioning bolt 1, and both are in contact with the outer wall of the object to be fastened, the internal thread 202 and the external thread of the outer wall of the positioning bolt 1 can bite each other, so that the positioning bolt 1 and the nut 201 are threadedly connected and fixed, and the object can be fastened, and both are existing technologies well known to operators; through the reinforcement mechanism 2, after the nut 201 is screwed on the positioning bolt 1, the three groups of rubber clamps 206 can fit with the outer wall of the positioning bolt 1 to increase the friction force on the positioning bolt 1, so that the fixing effect between the nut 201 and the positioning bolt 1 is better; and combined with the setting of the limiting mechanism 3, the position of the nut 201 on the positioning bolt 1 can be fixed, so that the nut 201 will not fall off from the outer wall of the positioning bolt 1 due to long use time or shaking of the fastened object and other situations, thereby further improving the fastening effect.

[0031] like Figures 3 to 6 As shown, the nut 201 is threadedly connected to the outer wall of the positioning bolt 1, and the round rod 205 is in contact with the inner wall of the positioning groove 207; the rubber clamp 206 is in contact with the outer wall of the positioning bolt 1, and the clamping block 210 is clamped with the clamping groove 211; one end of the connecting spring 209 is fixedly connected to the outer wall of the clamping block 210, and the other end of the connecting spring 209 is fixedly connected to the inner wall of the fixing block 208; the fixing block 208 passes through the outer wall of the nut 201, and the clamping block 210 is slidably connected to the inner wall of the fixing block 208.

[0032] The above scheme is adopted: after the positioning bolt 1 passes through the threaded hole on the surface of the object to be fastened, the nut 201 can be screwed on the positioning bolt 1. Before screwing, the positions of the three groups of rubber clamping blocks 206 need to be adjusted to the inner wall of the nut 201 to avoid resistance during the screwing process; the slots 211 are provided with two groups, and the fixing block 208 passes through the outer wall of one side of the nut 201. By turning the fixing block 208, the rotating plate 203 can be driven to rotate. When the rotating plate 203 rotates, the arc groove 204 generates a squeezing force on the outer wall of the round rod 205, and because the round rod 205 The rod 205 contacts the inner wall of the positioning groove 207. Guided by the positioning groove 207, the round rod 205 moves along the inner wall of the positioning groove 207 during the rotation of the rotating plate 203, so that the three groups of round rods 205 can drive the corresponding three groups of rubber clamping blocks 206 to move toward the middle or outside at the same time; when the rotating plate 203 rotates until the three groups of round rods 205 move outward to the inner wall of the nut 201 at the same time, the nut 201 can be screwed onto the positioning bolt 1. During the screwing process, the rubber clamping block 206 does not contact the outer wall of the positioning bolt 1, that is, no resistance is generated.

[0033] When not affected by external force, the connecting spring 209 drives the card block 210 to remain in the state of popping out and engaging with one of the groups of card slots 211 due to its own elastic force. Two groups of protrusions are provided on the card block 210, one group of protrusions is always engaged with the card slot 211, and the other group of protrusions is always on the outside. When it is necessary to rotate the rotating plate 203, the outer group of protrusions can be pressed to drive the card block 210 to move as a whole to the inner wall of the fixed block 208, and the connecting spring 209 is forced to shrink, and the internal protrusion is out of contact with the card slot 211, so that the limit of the fixed block 208 and the rotating plate 203 can be released, and the rotating plate 203 can be rotated; when the rotating plate 203 is rotated to the point where the three groups of rubber clamps 206 are all at the outermost side, the card block 210 can be released, and the connecting spring 209 drives the card block 210 to pop out due to its own elastic force, so that the protrusion is engaged with the other group of card slots 211 When the nut 201 is screwed to fit the object to be fastened, the clamping block 210 can be pressed again and the fixing block 208 can be reversed to make the rotating plate 203 rotate in the opposite direction. At this time, the rotating plate 203 drives the round rod 205 and the corresponding rubber clamping block 206 to move toward the middle at the same time. When the three groups of rubber clamping blocks 206 are all in contact with the outer wall of the positioning bolt 1, the clamping block 210 can be loosened to make it engage with the clamping groove 211 to complete the limiting of the rotating plate 203 and fix the three groups of rubber clamping blocks 206. Since the rubber clamping block 206 is made of rubber material, when it fits and is fixed to the outer wall of the positioning bolt 1, it will produce a certain deformation, so that it fits more closely with the positioning bolt 1, thereby improving the fixing effect of the positioning bolt 1.

[0034] like Figure 7 and Figure 8As shown, the limiting mechanism 3 includes a threaded rod 301, the outer wall of the threaded rod 301 is threadedly connected to a slider 304, the inner wall of the positioning bolt 1 is slidably connected to a sleeve rod 302, the inner wall of the sleeve rod 302 is provided with a groove 303, the outer wall of the slider 304 is fixedly connected to a guide rod 305, the outer wall of the slider 304 is fixedly connected to a connecting block A306, the outer wall of the connecting block A306 is hinged to a connecting block B308 through a connecting rod 307, the inner wall of the sleeve rod 302 is slidably connected to two groups of plug blocks 309, and the inner wall of the nut 201 is provided with an annular groove 5.

[0035] The above scheme is adopted: the sleeve rod 302 can only move up and down in the inner wall of the positioning bolt 1, but cannot rotate, while the threaded rod 301 can only rotate in the inner wall of the sleeve rod 302 and cannot move up and down; the slider 304 slides on the inner wall of the groove 303 through the guide rod 305, and under the guiding effect of the groove 303, the threaded rod 301 can only drive the slider 304 and the guide rod 305 to move up and down along the inner wall of the groove 303 when rotating, and will not rotate with the threaded rod 301; the plug block 309 and the connecting rod 307 are both provided with two groups, symmetrically distributed on both sides of the threaded rod 301, and the plug block 309 can only move horizontally in the inner wall of the sleeve rod 302. When the slider 304 moves up and down, it will drive the connecting rod 307 to flip. When the connecting rod 307 flips, it will drive the two groups of plug blocks 309 to move. 9 is guided by the inner wall of the sleeve rod 302 and moves toward the middle or both sides at the same time; when the sleeve rod 302 is pulled up and down, the two groups of plug blocks 309 will move synchronously in the inner wall of the through groove 4. After the nut 201 and the positioning bolt 1 have completed the tightening of the object, the plug blocks 309 can be moved to both sides and contact with the inner wall of the annular groove 5, so that the nut 201 will not move up and down on the outer wall of the positioning bolt 1. When the object to be tightened shakes or other factors touch the nut 201, the nut 201 may rotate, but because the nut 201 is threadedly connected to the positioning bolt 1, the nut 201 will inevitably move up and down along the surface of the positioning bolt 1 when it rotates, but the contact of the plug blocks 309 with the annular groove 5 will prevent the nut 201 from moving up and down, thereby fixing the nut 201 and the positioning bolt 1, further improving the connection and tightening effect.

[0036] like Figure 7 and Figure 8 As shown, the threaded rod 301 is rotatably connected to the inner wall of the sleeve rod 302, and the guide rod 305 is slidably connected to the inner wall of the groove 303; one end of the connecting rod 307 is hinged to the outer wall of the connecting block B308, and the other end of the connecting rod 307 is hinged to the outer wall of the connecting block A306; the plug block 309 contacts the inner wall of the arc groove 204, and the plug block 309 passes through the inner wall of the through groove 4; the plug block 309 passes through the outer wall of the sleeve rod 302, the sleeve rod 302 passes through the top outer wall of the positioning bolt 1, and the threaded rod 301 passes through the top outer wall of the sleeve rod 302.

[0037] The above scheme is adopted: when the nut 201 is screwed on the positioning bolt 1, the insert block 309 needs to be retracted into the inner wall of the sleeve rod 302 so that it does not penetrate the through groove 4 and does not contact the outer wall of the nut 201; at this time, the threaded rod 301 can be rotated to drive the slider 304 to move upward, the two sets of connecting rods 307 are flipped, and the connecting block B308 and the insert block 309 are driven to move toward the middle at the same time, and can be retracted into the inner wall of the sleeve rod 302; when the nut 201 is threadedly connected with the positioning bolt 1 and is located on both sides of the object to be fastened, due to the different thicknesses of the object, the position of the nut 201 on the positioning bolt 1 is also different, but the annular groove 5 always corresponds to one point of the through groove 4. At this time, the sleeve rod 302 can be pulled up and down according to the position of the nut 201. The sleeve rod 302 drives the plug block 309 to move to the position corresponding to the annular groove 5, and the threaded rod 301 can be rotated in the opposite direction to make the slider 304 move downward, and the connecting block B308 and the plug block 309 can be driven to move to both sides at the same time through the connecting rod 307, and the plug block 309 passes through the through groove 4 and contacts the inner wall of the annular groove 5 to complete the fixation; at this time, since the nut 201 is connected and fixed to the positioning bolt 1, the position of the sleeve rod 302 and the threaded rod 301 is also fixed, and the adjustment can be completed without the need for additional fixation of the two, and the fixing effect is automatically completed; thereby, the fixing effect between the nut 201 and the positioning bolt 1 can be further improved, so that the nut 201 will not fall off from the positioning bolt 1 due to collision or other influences, thereby improving the tightening effect.

[0038] The working principle and use process of the present invention:

[0039] The positioning bolt 1 can be screwed through the threaded hole of the object to be fastened, and the clamping block 210 is pressed to shrink the connecting spring 209, and the clamping block 210 moves to the inner wall of the fixed block 208, and is out of contact with one set of the clamping grooves 211, thereby releasing the limit of the fixed block 208 and the rotating plate 203, and then the fixed block 208 is moved to drive the rotating plate 203 to rotate, and the arc groove 204 squeezes the round rod 205, and the round rod 205 moves under the guidance of the positioning groove 207, so that the three sets of round rods 205 drive the rubber clamping block 206 Move it to the inner wall of the nut 201, and loosen the block 210, which pops out under the elastic force of the connecting spring 209 and engages with another set of slots 211, so that the position of the rotating plate 203 and the rubber clamp 206 is fixed; for the limiting mechanism 3, it is necessary to first rotate the threaded rod 301 to make the slider 304 move upward, and the movement of the slider 304 drives the connecting rod 307 to flip, so that the two sets of plug blocks 309 move toward the middle and are retracted into the inner wall of the sleeve rod 302, so that they do not pass through the through slot 4 and do not contact the outer wall of the nut 201.

[0040] Then screw the nut 201 onto the positioning bolt 1 from below, rotate the nut 201 so that both are in contact with the outer wall of the object to be fastened, and achieve threaded connection through the engagement of the internal thread 202 of the nut 201 with the external thread of the positioning bolt 1 to complete the fastening of the object.

[0041] The nut 201 with the rubber clamp block 206 adjusted in position is screwed onto the positioning bolt 1. When the nut 201 is fitted with the object to be fastened, the clamp block 210 is pressed again and the fixing block 208 is toggled in the opposite direction to cause the rotating plate 203 to rotate in the opposite direction, driving the round rod 205 and the rubber clamp block 206 to move toward the middle until the three groups of rubber clamp blocks 206 are fitted with the outer wall of the positioning bolt 1. The clamp block 210 is then released. Under the elastic force of the connecting spring 209, the clamp block 210 pops out and engages with a group of slots 211, completing the limiting of the rotating plate 203 and fixing the rubber clamp block 206. Since the rubber clamp block 206 is made of rubber material, it will be deformed when it is fitted and fixed with the outer wall of the positioning bolt 1, thereby fitting more closely with the positioning bolt 1, increasing the friction force on the positioning bolt 1, and strengthening the fixing effect of the nut 201 and the positioning bolt 1.

[0042] When the nut 201 is threadedly connected with the positioning bolt 1 and is located on both sides of the object to be fastened, according to the different positions of the nut 201 on the positioning bolt 1 caused by the thickness of the object, the sleeve rod 302 is pulled up and down to move the plug block 309 to the position corresponding to the annular groove 5, and then the threaded rod 301 is rotated in the opposite direction, the slider 304 moves downward, and the plug block 309 is driven to move to both sides through the connecting rod 307. The plug block 309 passes through the through groove 4 and contacts the inner wall of the annular groove 5. At this time, even if the object to be fastened shakes or other factors cause the nut 201 to rotate, due to the threaded connection between the nut 201 and the positioning bolt 1, the rotation of the nut 201 will have a tendency to move up and down, and the contact between the plug block 309 and the annular groove 5 limits the up and down movement of the nut 201, thereby fixing the position of the nut 201 on the positioning bolt 1, further improving the connection and tightening effect, and preventing the nut 201 from falling off the positioning bolt 1 due to various external factors.
