Description

Technical Field

[0001] This utility model belongs to the field of fastener technology and relates to bolts for fixing high adjusters. Background Technology

[0002] As a crucial fastener, the bolt for fixing the high adjuster plays an indispensable role in various equipment. With its unique structure and performance, it is specifically designed to accurately and securely fix the high adjuster to a specific location or structure, ensuring the stable and reliable operation of the entire equipment system.

[0003] However, in actual application scenarios, the bolts used to fix the high-adjustment device will inevitably be subjected to collisions and impacts from external objects or the environment. Such collisions will cause continuous or intermittent vibrations, and the dynamic force generated by the vibrations will continue to act on the thread engagement between the bolt and the connecting parts, as well as the contact area between the bolt head and the fixed surface, gradually destroying the stable clamping state established by the bolt preload, and thus causing the bolt to loosen. Utility Model Content

[0004] The technical problem to be solved by this utility model is that in actual application scenarios, the bolts used to fix the high-adjustment device will inevitably be subjected to collisions and impacts from external objects or the environment. Such collisions will cause continuous or intermittent vibrations, and the dynamic force generated by the vibrations will continue to act on the thread engagement between the bolt and the connecting parts and the contact area between the bolt head and the fixed surface, gradually destroying the stable clamping state established by the bolt preload, and thus causing the bolt to loosen.

[0005] The high-adjustment fixing bolt described in this utility model includes a bolt body, a connecting post fixedly connected to one end of the bolt body, a first rectangular plate fixedly connected to the end of the connecting post near the bolt body, a second rectangular plate fixedly connected to the end of the connecting post away from the bolt body, and a hexagonal head fixedly connected to the end of the connecting post away from the bolt body. The side of the first rectangular plate near the bolt body is fixedly connected to the bolt body, and the side of the second rectangular plate near the hexagonal head is fixedly connected to the hexagonal head. Shock-absorbing components are provided on both sides of the second rectangular plate.

[0006] The shock absorption assembly includes two sets of first connecting plates, two sets of second connecting plates, a connecting shaft, and two sets of guide shafts. The first connecting plates are fixedly connected to the bottom sides of the second rectangular plate, and the second connecting plates are fixedly connected to the top sides of the first rectangular plate. The two ends of the connecting shaft are fixedly connected to the sides of the two sets of first connecting plates that are close to each other, and the two ends of the two guide shafts are fixedly connected to the sides of the two sets of second connecting plates that are close to each other.

[0007] The damping assembly also includes two sets of first notched sliding plates, two sets of spring dampers, and two sets of second notched sliding plates. The two first notched sliding plates are slidably connected to the middle of the connecting shaft. The two spring dampers are fixedly connected to the sides of the two sets of second connecting plates that are close to each other. The two second notched sliding plates are fixedly connected to the ends of the two sets of spring dampers that are close to each other. The bottom of the two second notched sliding plates is slidably connected to the middle of the two sets of guide shafts. The bottom of the two second notched sliding plates is provided with an auxiliary support mechanism.

[0008] The shock absorption assembly further includes a first horizontal shaft, a second horizontal shaft, and a support plate. The first horizontal shaft is fixedly connected to the groove at the bottom of the first grooved slide plate, and the second horizontal shaft is fixedly connected to the groove at the top of the second grooved slide plate. One end of the support plate is rotatably connected to the middle of the first horizontal shaft, and the other end of the support plate is rotatably connected to the middle of the second horizontal shaft.

[0009] The auxiliary support mechanism includes two sets of support slide rods and two sets of limiting slide grooves.

[0010] The bottom ends of the two support slide rods are slidably connected to the middle of the two sets of limiting slide grooves, and the two sides of the bottom ends of the two support slide rods are respectively in contact with the two sides of the two sets of limiting slide grooves.

[0011] Compared with the prior art, the beneficial effects of this utility model are: by setting the shock absorption component, the vibration force between the bolt body and the fixed surface can be reduced when the high adjuster is subjected to external impact, thereby preventing the bolt body from loosening easily due to the action of vibration force, which would reduce the connection strength and stability between the high adjuster and the installation structure, seriously affect the normal working performance and operation stability of the high adjuster, and in severe cases may even cause equipment failure or safety accidents.

[0012] By setting up an auxiliary support mechanism, the second slotted slide can be further supported, thereby improving the stability of the second slotted slide and enhancing the reliability of the shock absorption components. Attached Figure Description

[0023] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0024] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0025] Example 1

[0026] like Figures 1-6As shown, the bolt for fixing the high-adjustment device includes a bolt body 1. A connecting post 11 is fixedly connected to one end of the bolt body 1. A first rectangular plate 12 is fixedly connected to the end of the connecting post 11 near the bolt body 1. A second rectangular plate 13 is fixedly connected to the end of the connecting post 11 away from the bolt body 1. A hexagonal head 14 is fixedly connected to the end of the connecting post 11 away from the bolt body 1. The side of the first rectangular plate 12 near the bolt body 1 is fixedly connected to the bolt body 1. The side of the second rectangular plate 13 near the hexagonal head 14 is fixedly connected to the hexagonal head 14. Shock-absorbing components are provided on both sides of the second rectangular plate 13.

[0027] The shock absorption assembly includes two sets of first connecting plates 2, two sets of second connecting plates 21, a connecting shaft 22, and two sets of guide shafts 23. The first connecting plates 2 are fixedly connected to the bottom sides of the second rectangular plate 13, the second connecting plates 21 are fixedly connected to the top sides of the first rectangular plate 12, the two ends of the connecting shaft 22 are fixedly connected to the sides of the two sets of first connecting plates 2 that are close to each other, and the two ends of the two guide shafts 23 are fixedly connected to the sides of the two sets of second connecting plates 21 that are close to each other.

[0028] The damping assembly also includes two sets of first notched sliding plates 3, two sets of spring dampers 31, and two sets of second notched sliding plates 32. The two first notched sliding plates 3 are slidably connected to the middle of the connecting shaft 22. The two spring dampers 31 are fixedly connected to the sides of the two sets of second connecting plates 21 that are close to each other. The two second notched sliding plates 32 are fixedly connected to the ends of the two sets of spring dampers 31 that are close to each other. The bottom of the two second notched sliding plates 32 is slidably connected to the middle of the two sets of guide shafts 23. The bottom of the two second notched sliding plates 32 is provided with an auxiliary support mechanism.

[0029] The shock absorption assembly also includes a first horizontal shaft 4, a second horizontal shaft 41, and a support plate 42. The first horizontal shaft 4 is fixedly connected to the groove at the bottom of the first grooved slide plate 3, the second horizontal shaft 41 is fixedly connected to the groove at the top of the second grooved slide plate 32, one end of the support plate 42 is rotatably connected to the middle of the first horizontal shaft 4, and the other end of the support plate 42 is rotatably connected to the middle of the second horizontal shaft 41.

[0030] During operation, when the hexagonal head 14 is turned to fix the height adjuster, the bolt body 1, the first rectangular plate 12, and the second rectangular plate 13 will rotate simultaneously. When the bolt body 1 is screwed into the predetermined position, the turning of the hexagonal head 14 can be stopped. The bottom of the first rectangular plate 12 will be in contact with the fixed surface. When the height adjuster is subjected to external impact and vibrates, the vibration force will be transmitted to the bolt body 1 and the fixed surface. At this time, the first rectangular plate 12 will vibrate under the influence of the vibration force, thereby transmitting the vibration force to the second connecting plate 21, the spring damper 31, and the second notched slide plate 32.

[0031] When the second notched sliding plate 32 receives vibration, it will slide in the middle of the guide shaft 23. While sliding, it will drive the second horizontal shaft 41 to move. The movement of the second horizontal shaft 41 will pull the bottom of the support plate 42, thereby forcing the support plate 42 to rotate in the middle of the second horizontal shaft 41 and change its angle. While the angle of the support plate 42 changes, its top will rotate in the middle of the first horizontal shaft 4 and pull the first notched sliding plate 3 to slide in the middle of the connecting shaft 22. While the second notched sliding plate 32 slides, it will also drive the spring damper 31 to be stretched. When stretched, the spring damper 31 will offset the stretching force under the influence of its own tension, thereby weakening the vibration force on the bolt body 1 and the fixed surface.

[0032] This step, through the setting of vibration damping components, can reduce the vibration force between the bolt body 1 and the fixed surface when the high adjuster is subjected to external impacts. This prevents the bolt body 1 from easily loosening due to vibration, thereby reducing the connection strength and stability between the high adjuster and the installation structure, seriously affecting the normal working performance and operational stability of the high adjuster, and in severe cases, even causing equipment failure or safety accidents.

[0033] Example 2

[0034] like Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the auxiliary support mechanism includes two sets of support slide rods 5 and two sets of limiting slide grooves 51. The top ends of the two support slide rods 5 are respectively fixedly connected to the bottom sides of the second slotted slide plate 32, and the two limiting slide grooves 51 are opened on the top sides of the first rectangular plate 12.

[0035] The bottom ends of the two support slide rods 5 are slidably connected to the middle of the two sets of limiting slide grooves 51, and the two sides of the bottom ends of the two support slide rods 5 are respectively in contact with the two sides of the two sets of limiting slide grooves 51.

[0036] During operation, when the second notched slide plate 32 slides under the action of vibration, it will drive the support slide rod 5 to move synchronously. When the support slide rod 5 moves, its bottom end will slide in the middle of the limiting slide groove 51. With the cooperation of the support slide rod 5 and the limiting slide groove 51, the second notched slide plate 32 can be provided with auxiliary support, and the sliding trajectory of the second notched slide plate 32 can also be restricted. This reduces the possibility that the second notched slide plate 32 is prone to twisting due to uneven force when sliding, which in turn causes the spring damper 31 to deform, reducing the stability and service life of the spring damper 31.

[0037] This step, through the setting of an auxiliary support mechanism, can provide auxiliary support for the second slotted slide plate 32, thereby improving the stability of the second slotted slide plate 32 and enhancing the reliability of the shock absorption component.
