Description

Technical Field

[0001] The invention belongs to the technical field of rail transportation, and in particular relates to a double-thread adjustment structure, a stepless self-adjusting height isolator and a rail system thereof. Background Art

[0002] With the rapid development of urban rail transit and intercity railways, the response of the rail system caused by the continuous increase in vehicle speed has gradually increased. The use of fasteners or ballast vibration isolation pads to isolate vibrations alone can no longer meet the requirements of some areas with special vibration reduction requirements. Floating slab ballast technology is one of the most effective track vibration and noise reduction technologies, especially in subways and urban light rails. This technology has been widely used.

[0003] The vibration isolator floating slab track bed has significant vibration reduction function and is widely used in projects. Conventional vibration isolators cannot achieve stepless height adjustment when they are replaced or repaired. Conventional pads are used to increase the height, but the pads are increased in a gradient manner and the accuracy cannot be controlled. In addition, the construction and operation and maintenance of vibration isolators are difficult. The outer sleeve of the existing vibration isolator is a pre-buried structure, which also increases the difficulty of construction and cannot be replaced.

[0004] Traditional vibration isolators have a limited adjustment range and low adjustment efficiency, and cannot take into account the adjustment of floating plates within different height adjustment ranges. Therefore, it is necessary to provide a structure or device that can be used with existing vibration isolators to achieve adjustment of the floating plate track system.

[0005] In addition, the existing series of vibration isolators are of various types, but none of them can achieve self-adjustment of the height of the vibration isolators, which affects the subsequent construction and maintenance and is very inconvenient.

[0006] Chinese patent CN201821392285.8 discloses a new type of intelligent steel spring floating plate structure for subway roadbed shock absorption system, in which the height or compression of the isolator cannot be adjusted by itself and can only be adjusted during installation. Since the floating plate is installed during adjustment, the adjustment is difficult, the effect is poor, and the accuracy is uncontrollable.

[0007] Chinese patent CN201620709585.9 discloses a spiral jacking spring shock absorber for a track floating plate, the height of which cannot be adjusted. Due to the spring component, the load-bearing state of the shock absorber can only be adjusted when the floating plate is installed, and the static height cannot be adjusted by itself, making adjustment inconvenient.

[0008] Chinese patent CN201610356937.1 discloses a screw vibration-damping isolator. Although it achieves the effect of stepless height adjustment of the floating plate, the height of the isolator itself cannot be adjusted. It is also limited only in the vertical direction. The stability of the isolator cannot be guaranteed in the longitudinal and transverse directions. When a train passes by, it will produce a large instability factor, affecting the use of the track system.

[0009] Chinese patent CN201610356938.6 discloses a screw vibration isolator floating plate track system and its lifting equipment and lifting method, so that the floating track plate can quickly and accurately complete the horizontal leveling and lifting actions. Similarly, the height adjustment of the vibration isolator itself is limited, and its longitudinal and lateral limits are relatively small. When adjusting, the overall rotation of the vibration isolator cannot be achieved, resulting in excessive friction consumption of internal components, thereby increasing maintenance costs.

[0010] Conventional threaded isolators are all steplessly adjusted through a single set of threads, and their adjustment capabilities are limited, the connection strength is low, and the adjustment efficiency is low. Based on the use environment of the floating plate track system, the existing single-threaded isolators have weak anti-loosening capabilities and cannot adapt to the growing use needs.

[0011] Therefore, how to provide a double-thread adjustment structure, a stepless self-adjusting height isolator and a track system thereof in view of the deficiencies in the prior art is a problem that needs to be urgently solved by those skilled in the art. Summary of the invention

[0012] In view of this, the present invention provides a double-thread adjustment structure, a stepless self-adjusting height isolator and its track system, which are easy to adjust and simple to construct. The height of the isolator itself can be adjusted before installation and use, which is convenient for the maintenance of the floating plate track system in the later stage.

[0013] In order to achieve the above object, the present invention adopts the following technical solution: a double-thread adjustment structure, which includes:

[0014] A threaded platform 1, wherein the threaded platform 1 is provided with an internal thread;

[0015] The second threaded platform has an internal thread or an external thread, and the first threaded platform and the second threaded platform are coaxially arranged; the second threaded platform has a central hole

[0016] The adjusting threaded barrel, the threaded platform 1 and the threaded platform 2 are threadedly connected to the two end edges of the adjusting threaded barrel, and the inner side wall and the outer side wall of the adjusting threaded barrel are both provided with threaded structures matching the threaded platform; the threaded structures on the inner side wall and the outer side wall of the adjusting threaded barrel have opposite rotation directions, and the threaded platform 1 and the threaded platform 2 are respectively threadedly connected to the outer side wall and the inner side wall of the adjusting threaded barrel; the rotation of the adjusting threaded barrel drives the threaded platform 1 and the threaded platform 2 to move away from or approach each other in the axial direction;

[0017] The threaded platform one or the threaded platform two is fixedly connected to the existing spring vibration isolator.

[0018] The beneficial technical effect of the present invention is that the structure can be used in conjunction with existing vibration isolators, which refer to spring vibration isolators or rubber vibration isolators conventionally used in floating plate track systems, to achieve stepless high-precision adjustment of the floating plate track system. When in use, it is only necessary to fix the threaded platform one or the threaded platform two close to the existing vibration isolator to the free end of the existing vibration isolator, and connect the remaining threaded platform one or the threaded platform two to the embedded sleeve of the floating plate. When adjusting, the adjustment threaded cylinder is turned, and the threaded platform one and the threaded platform two are axially displaced. The mutual approach or distance of the two threaded platforms in the axial direction has double the height adjustment efficiency relative to the stepless adjustment of a single thread, and effectively improves the work efficiency of lifting the floating plate during installation.

[0019] Preferably, two thread segments with opposite rotation directions are provided on the outer side wall of the adjusting threaded barrel, and the threaded platform 1 and the threaded platform 2 are respectively threadedly connected to the two ends of the outer side of the adjusting threaded barrel.

[0020] The resulting technical effect is that the combination of double threads with different rotation directions has double the height adjustment efficiency compared to the stepless adjustment of a single thread. At the same time, compared to the stepless height adjustment of a single thread, the different rotation direction mechanisms of the double threads have symmetry in displacement adjustment. It is only necessary to constrain the displacement of any one end of the double thread, and the other end of the thread will be completely restricted, providing a very reliable anti-loosening property.

[0021] Preferably, threads are provided on the inner and outer side walls of the adjusting threaded barrel, the threads on the corresponding inner and outer side walls of the adjusting threaded barrel have opposite rotation directions, and the threaded platform 1 and the threaded platform 2 are respectively threadedly connected to the outer side and the inner side of the adjusting threaded barrel.

[0022] The resulting technical effect is: in order to have a stronger structural performance, a layered design is adopted, that is, threads are set on the inner and outer sides of the adjusting threaded barrel. Compared with the single-threaded steplessly adjustable threaded external structure, the double-threaded internal thread is not limited in space, so the thread strength design can be increased, providing a stronger structural form.

[0023] Preferably, an angular limit plate is fixed on the outer wall of the threaded platform one or the threaded platform two, and a travel groove is opened on the angular limit plate corresponding to the axial direction of the threaded platform one or the threaded platform two, and a slider is adapted to be slidably connected in the travel groove, and the slider is fixed on the threaded platform two or the threaded platform one and prevents the threaded platform one and the threaded platform two from rotating relative to each other.

[0024] The resulting technical effect is that the cooperation between the angular limit plate and the slider can prevent the relative rotation of threaded table 1 and threaded table 2. It can be understood that when adjusting the rotation of the threaded barrel, threaded table 1 and threaded table 2 only move axially but do not rotate circumferentially, thereby avoiding the rotation of the existing vibration isolator used in conjunction with the threaded barrel.

[0025] Preferably, the stroke size of the stroke slide groove is smaller than the distance size for adjusting the threaded barrel to drive the threaded platform 1 and the threaded platform 2 to move axially.

[0026] The resulting technical effect is: utilizing the limit of the slider in the travel slot to ensure an effective adjustment range, avoiding the reduction of the stressed thread during the height adjustment process and resulting in insufficient thread strength, thereby ensuring the stability of the component.

[0027] Preferably, there are a plurality of angular limit plates, which are arranged at intervals on the outer peripheral side of the threaded platform 1 and / or the threaded platform 2, and each of the angular limit plates is used in conjunction with a sliding block.

[0028] The technical effect produced thereby is: the cooperation between the plurality of angular limit plates and the slider prevents the relative rotation between the threaded platform 1 and the threaded platform 2.

[0029] Preferably, the outer periphery of the threaded platform 1 is provided with a plurality of lugs for use with the embedded sleeve of the floating plate, and the threaded platform 2 is provided with a seat plate fixedly connected to the existing spring isolator, and the seat plate is detachably screwed or non-detachably fixedly connected to the top free end of the existing spring isolator.

[0030] The resulting technical effect is that the lug is used in conjunction with the pre-buried sleeve of the floating plate in the later stage, thereby effectively achieving the lifting and supporting effect of the vibration isolator and the floating plate.

[0031] Preferably, the interior of the adjusting threaded barrel is formed with an inner hexagonal hole structure.

[0032] The resulting technical effect is that the adjusting threaded barrel is an active adjusting part, and the inner hexagonal hole structure arranged therein can cooperate with an external screwing tool to achieve lifting adjustment.

[0033] The present invention discloses a stepless self-adjustable height vibration isolator, comprising an elastic buffer and a fixed seat, and also comprising the above-mentioned double-thread adjustment structure, wherein the double-thread adjustment structure is located above the elastic buffer, and the fixed seat is located below the elastic buffer, and the threaded platform 2 in the double-thread adjustment structure rotates synchronously with the fixed seat, and the adjustment threaded cylinder in the double-thread adjustment structure rotates to change the static height of the vibration isolator.

[0034] The beneficial effects of the present invention are as follows: the vibration isolator of this scheme is different from the existing vibration isolators, and is equipped with a double-threaded adjustment structure, and the double-threaded adjustment structure is located on the upper part of the elastic body, which is an upper-mounted adjustment. The height of the vibration isolator itself is based on the topmost threaded platform and the bottommost fixed seat. The height of the vibration isolator can be adjusted by rotating the adjustment threaded barrel. In other words, the height of the vibration isolator itself and the support height can be adjusted at the same time, which is not the case with the conventional vibration isolator. The height only relies on the compression adjustment of the elastic part. In specific use, it is only necessary to rotate the adjustment threaded barrel inside the vibration isolator, and the force application is simple and convenient. More importantly, the vibration isolator is provided with a double set of reverse threads, which can realize the synchronous adjustment of the isolator height and the support height through self-rotation, greatly improving the construction efficiency.

[0035] Preferably, a center hole is provided on the threaded platform No. 2, and a center rod is connected to the center hole; the fixed seat is located below the threaded platform No. 2 as a supporting base, the elastic buffer is located between the fixed seat and the threaded platform No. 2 and drives the fixed seat and the threaded platform No. 2 to move axially, and the threaded platform No. 2 cooperates with the fixed seat sleeve and can rotate synchronously; the center rod passes through the threaded platform No. 2, the elastic buffer and is detachably connected to the fixed seat, and a nut is connected to the top end of the center rod and limits the maximum spacing distance between the threaded platform No. 2 and the fixed seat.

[0036] The technical effect produced by this is: it can be understood that the center rod connects the threaded table 2, the elastic buffer and the fixed seat, and the threaded table 2 cooperates with the fixed seat sleeve and can rotate synchronously. That is, when the entire vibration isolator is in use, except for adjusting the threaded cylinder as a rotating part, the rest cannot rotate, and the components cannot rotate relative to each other to avoid friction and wear.

[0037] Preferably, an elastic buffer abutment platform is provided on the bottom side of the threaded platform 2, and the elastic buffer abutment platform abuts against the top of the elastic buffer. An elastic buffer support platform is provided on the top of the fixed seat, and the elastic buffer support platform abuts against the bottom of the elastic buffer.

[0038] The resulting technical effect is: the elastic buffer is supported and connected by the elastic buffer abutment platform and the elastic buffer support platform, thereby ensuring the axial stability and reliability of the vibration isolator.

[0039] Preferably, an outwardly protruding square rod with a hole is provided in the middle of the bottom of the threaded platform 2, an inner square hole matching the square rod with a hole is provided in the middle of the fixing seat, the square rod with a hole is slidably connected in the inner square hole up and down, and the center rod is located in the hole of the square rod with a hole.

[0040] The resulting technical effect is that the square rod with holes cooperates with the inner square hole to ensure the anti-rotation relationship between the fixed seat and the second threaded platform, and also provide the longitudinal and lateral stability of the vibration isolator to prevent the vibration isolator itself from shaking and deviating.

[0041] Preferably, a first staggered tooth structure is arranged around the bottom circumference of the threaded table 2, and a second staggered tooth structure is arranged around the top circumference of the fixed seat. The first staggered tooth structure and the second staggered tooth structure are adapted to be plugged in and rotate synchronously, and there is a downward pressure gap between the teeth of the first staggered tooth structure and the corresponding grooves of the second staggered tooth structure.

[0042] The resulting technical effect is that this solution is another structural form for preventing rotation between the threaded platform 2 and the fixed seat, and this structure will not affect the axial displacement between the threaded platform 2 and the fixed seat.

[0043] Preferably, a first cylinder structure extends from the bottom of the threaded table 2, a limit groove is provided on the inner side of the first cylinder structure, a second cylinder structure is provided on the top of the fixed seat, a limit block is provided on the outer wall of the second cylinder structure, the first cylinder structure is adapted to be inserted into the outer side of the second cylinder structure and rotate synchronously, the limit block is adapted to be slidably connected with the limit groove, and the limit block has a travel sliding range in the limit groove.

[0044] The resulting technical effect is that this structural form not only ensures that the threaded table 2 and the fixed seat cannot rotate relative to each other, but also provides a good longitudinal and lateral limiting effect. At the same time, the downward pressure gap between the limiting groove of the first cylinder structure and the corresponding limiting block of the second cylinder structure can ensure that the elastic buffer can play a role.

[0045] Preferably, an inner square structure outer sleeve is axially extended corresponding to the bottom of the threaded platform 2, and an outer square structure is provided on the top edge of the fixed seat. The outer square structure is adapted to be plugged in and synchronously rotated with the corresponding inner square structure outer sleeve, and a downward pressure gap exists between the outer square structure and the corresponding inner square structure outer sleeve.

[0046] The resulting technical effect is that this solution is another structural form for preventing the second threaded platform and the fixed seat from rotating, and this structural form also satisfies the compression effect of the elastic buffer.

[0047] Preferably, a locking hole is provided on the inner side wall of the adjusting threaded barrel, a locking screw is connected in the locking hole, and the locking screw is tightly fixed to the inner side wall of the threaded platform.

[0048] The resulting technical effect is that the threaded barrel can be prevented from loosening by means of the locking screw.

[0049] Preferably, a locking plate is provided on the inner top of the threaded platform 1, and the locking plate abuts against the adjusting threaded barrel and prevents the adjusting threaded barrel from loosening.

[0050] The resulting technical effect is: after the adjustment is completed, the locking plate is installed to further prevent the adjustment threaded barrel from rotating, thereby achieving an anti-loosening effect.

[0051] Preferably, the elastic buffer member abutting platform is a conical platform or a folded platform, the elastic buffer member supporting platform is a conical platform or a flat platform, and the elastic buffer member is located between the elastic buffer member abutting platform and the elastic buffer member supporting platform.

[0052] The resulting technical effect is that the elastic buffer has a variety of structural forms, and different structural forms require matching abutment platform structures and support platform structures to ensure stable installation of the elastic buffer.

[0053] Preferably, the elastic buffer is a single spring member or a double spring member or a rubber-steel plate composite member or a composite rubber spring member.

[0054] The resulting technical effect is that the elastic buffer is the core component of the vibration isolator, and its structural form is not limited to a single spring component, a double spring component, a rubber-steel plate composite component, a composite rubber spring component, etc.

[0055] Preferably, when the elastic buffer is a single spring member, the structural form of the spring includes but is not limited to an equal-diameter spring, a conical spring, a thin waist spring, and a spindle spring.

[0056] Preferably, when the elastic buffer is a double spring member, the springs are arranged in an inner and outer layer arrangement, and the elastic moduli of the inner and outer springs are the same or different.

[0057] Preferably, when the elastic buffer is a rubber-steel plate composite part, the rubber and the steel plate are laminated to form a molded structure, and the molded structure includes but is not limited to a V-shaped structure, a folded structure, and a flat structure.

[0058] Preferably, when the elastic buffer is a composite rubber spring, the spring is embedded in a rubber block or a rubber tube, and the molding structure includes but is not limited to equal-diameter composite rubber springs, composite conical springs, composite thin-waist springs, composite spindle-shaped springs, and composite double springs.

[0059] The resulting technical effect is: according to different use environments and requirements of the vibration isolator, the structural form of the elastic buffer is reasonably selected.

[0060] The present invention discloses a track system, which includes using a plurality of the above-mentioned stepless self-adjusting vibration isolators, a plurality of groups of embedded sleeves and a plurality of floating plates, wherein the plurality of groups of the embedded sleeves are arranged at intervals inside the floating plates, and the plurality of stepless self-adjusting vibration isolators are located one by one inside the embedded sleeves, a top plate is fixed to the inner top of the embedded sleeves, a notch is provided on the top plate for the avoidance lug to pass through, the threaded platform is supported and connected to the bottom of the top plate through the lug, a plurality of the floating plates are placed above the foundation along the length direction of the track, and two adjacent floating plates are connected through a joint limiting structure, and the fixing seat at the bottom of the vibration isolator is positioned on the foundation.

[0061] The technical effect produced thereby is that the track system used with the stepless self-adjusting vibration isolator is convenient for later maintenance and simple for installation, greatly improving the construction efficiency. Compared with the single-threaded stepless adjustment thread directly matched with the embedded threaded cylinder, the vibration isolator of the present invention has a simple force structure matched with the embedded cylinder, and the double-threaded stepless adjustment structure is independent and flexibly arranged, which is convenient for later maintenance and replacement and has high feasibility.

[0062] Preferably, a limit baffle and a rotation stop block are provided on the inner side wall of the embedded sleeve, and the limit baffle and the rotation stop block are located below the top plate and on both sides of the lug, the limit baffle is used to limit the threaded platform 1 and the lug from entering the rotation end position of the embedded sleeve, and the rotation stop block is used to prevent the lug and the threaded platform 1 from rotating, and the lug is slidably engaged in the channel groove formed by the limit baffle and the rotation stop block.

[0063] The technical effect produced thereby is: when the vibration isolator of the present invention is installed, the vibration isolator enters the embedded sleeve and rotates the installation position until the lug abuts against the limit baffle. At this time, the lug of the vibration isolator will slide into the channel groove formed by the limit baffle and the rotary block to ensure that the vibration isolator body will not rotate. Subsequently, it is only necessary to rotate the adjustment threaded cylinder.

[0065] The resulting technical effect is that adjacent floating plates are connected via a joint limiting structure. Specifically, the joint limiting structure has a variety of specific implementation forms, including but not limited to positioning bosses, shear hinges, and wet joint connections, which can be reasonably selected according to construction needs.

[0066] Preferably, it further comprises a positioning shaft, which is fixed on the foundation; a positioning pin hole matching the positioning shaft is provided on the fixing seat at the bottom of the vibration isolator.

[0067] The resulting technical effect is that the positioning axis is used for positioning between the isolator and the foundation, and it can be specifically arranged according to the layout of the joint limiting structure. For example, the floating plates are connected by shear hinges, so the isolator needs to be positioned by the positioning axis to ensure the stable positioning of the entire track system. When the floating plates are connected by positioning bosses, the positioning bosses themselves are fixed to the foundation, so the positioning axis can be omitted between the isolator and the foundation. Therefore, the setting of the positioning axis needs to be determined by the construction requirements.

[0068] Preferably, the embedded sleeve is detachably connected with a cover above the top plate.

[0069] The resulting technical effect is: utilizing the cover to ensure the internal use environment of the vibration isolator and extend its service life.

The outer square structure is adapted to be plugged in and synchronously rotated with the corresponding inner square structure outer sleeve, and a downward pressure gap exists between the outer square structure and the corresponding inner square structure outer sleeve.

[0079] The resulting technical effect is that the above-mentioned solutions all provide anti-rotation restrictions for the fixing seat and the threaded platform, and also provide longitudinal and lateral restriction effects for the elastic buffer, thereby ensuring the use of the vibration isolator and the operational stability of the track system.

[0080] Preferably, a locking hole is provided on the inner side wall of the adjusting threaded barrel, a locking screw is connected in the locking hole, and the locking screw is tightly fixed to the inner side wall of the second threaded platform to prevent the adjusting threaded barrel from loosening.

[0084] Preferably, when the elastic buffer is a double spring member, the springs are arranged in an inner and outer layer arrangement, and the elastic moduli of the inner and outer springs are the same or different.

[0085] Preferably, when the elastic buffer is a rubber-steel plate composite part, the rubber and the steel plate are laminated to form a molded structure, and the molded structure includes but is not limited to a V-shaped structure, a folded structure, and a flat structure.

At this time, the flange of the vibration isolator will slide into the channel groove formed by the limit baffle and the rotary block to ensure that the vibration isolator body will not rotate. Subsequently, it is only necessary to use a tool to reach into the interior of the vibration isolator and rotate the adjustment threaded cylinder to achieve the height adjustment of the floating plate.

DETAILED DESCRIPTION

[0150] 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.

[0151] See the attached Figures 1 to 5 According to an embodiment of the present invention, a double-threaded adjustment structure can be used in conjunction with an existing spring isolator 4, which includes:

[0152] A threaded platform 1, wherein the threaded platform 1 is provided with an internal thread 1;

[0153] The threaded platform 2 is provided with an internal thread 2, the threaded platform 1 and the threaded platform 2 are coaxially arranged, and the internal thread 1 and the internal thread 2 are rotated in opposite directions, that is, if the internal thread 1 is left-handed, the internal thread 2 is right-handed;

[0154] Adjust the threaded barrel 3. Two external thread sections are provided on the outer wall of the adjusting threaded barrel 3 and correspond to the internal thread one and the internal thread two respectively. The rotation directions of the two external thread sections are opposite to achieve a double axial displacement adjustment effect. The rotation of the adjusting threaded barrel 3 drives the threaded platform 1 and the threaded platform 2 2 to move away from or approach each other in the axial direction. The threaded platform 1 or the threaded platform 2 2 can be fixedly connected to the existing spring vibration isolator 4.

[0155] Specifically, an angular limit plate 5 is fixedly connected to the outer wall of the threaded platform 1 or the threaded platform 2 by four screws, and a travel groove 6 is opened on the angular limit plate 5 corresponding to the axial direction of the threaded platform 1 or the threaded platform 2. The groove direction of the travel groove corresponds to the axial direction of the internal thread 1 or 2. A slider 7 is adapted for sliding connection in the travel groove 6. The slider 7 is fixed on the threaded platform 1 or the threaded platform 2 and prevents the threaded platform 1 and the threaded platform 2 from rotating relative to each other.

[0156] More specifically, the stroke size of the stroke slot 6 is smaller than the distance size of the axial movement of the threaded barrel 3 to drive the threaded table 1 and the threaded table 2, so that the height adjustment of the threaded table is effectively limited, ensuring sufficient tooth support, avoiding unbundling while ensuring the strength of use, and avoiding the reduction of the stressed thread teeth during the height adjustment process and the resulting insufficient thread strength; thereby improving the integrity and safety stability of the product.

[0157] In a specific implementation, there are three angular limit plates 5 , which are arranged at intervals on the outer circumference of the threaded platform 1 and the threaded platform 2 2 , and each angular limit plate 5 is used in conjunction with a slider 7 .

[0158] The top periphery of the threaded platform 1 is provided with three lugs 8 for use with the embedded sleeve of the floating plate, and the three lugs are arranged at an angle of 120°. The threaded platform 2 is provided with a seat plate 9 fixedly connected to the existing spring isolator 4. The seat plate 9 is fixedly connected to the top free end of the existing spring isolator 4 with screws to ensure the integrity and stability of later use.

[0159] In order to facilitate the screwing and adjusting of the threaded barrel 3 , an inner hexagonal hole structure 10 is provided inside the threaded barrel 3 for easy screwing with an external tool, thereby improving the convenience of product use.

[0160] The present invention also discloses another double-thread adjustment structure, see the attached Figure 6-7 This structural form has evolved into a new form of vibration isolator and track system usage status. Please refer to the attached Figure 8-10 .

[0161] The structure is in the form of an inner and outer sleeve arrangement of a threaded platform 1, an adjusting threaded barrel 3, and a threaded platform 2. The inner and outer side walls of the adjusting threaded barrel are provided with threads of opposite rotation directions. The threaded platform 1 is threadedly connected to the outer side of the adjusting threaded barrel 3, and the threaded platform 2 is threadedly connected to the inner side of the adjusting threaded barrel, forming two groups of threads with opposite rotation directions. When the adjusting threaded barrel is rotated, the height of the entire vibration isolator itself and the height of the floating plate support can be adjusted at the same time. The built-in space of the thread in this structure is not limited, so the thread strength design can be increased, providing a stronger structure.

[0162] Based on the above two double thread adjustment structures

[0163] The present invention discloses a stepless self-adjusting vibration isolator. Embodiment 1 is an upper-mounted adjustable vibration isolator. Figure 11-12 It includes a double-thread adjustment structure, an elastic buffer 11 and a fixed seat 12. The double-thread adjustment structure is located above the elastic buffer 11, and the fixed seat 12 is located below the elastic buffer 11. The threaded platform 2 in the double-thread adjustment structure rotates synchronously with the fixed seat 12, and the adjustment threaded cylinder 3 in the double-thread adjustment structure rotates to change the static height of the vibration isolator.

[0164] Specifically, a center hole is provided on the threaded platform 2, and a center rod 13 is connected to the center hole; the fixed seat 12 is located below the threaded platform 2 as a supporting base, and the elastic buffer 11 is located between the fixed seat 12 and the threaded platform 2 and drives the fixed seat 12 and the threaded platform 2 to move axially, which is the basis for the elastic buffer to play a role. The threaded platform 2 and the fixed seat 12 sleeve cooperate and can rotate synchronously to ensure the longitudinal and lateral limiting and axial adjustment accuracy of the vibration isolator; the center rod 13 passes through the threaded platform 2, the elastic buffer 11 and is detachably connected to the fixed seat 12. The top of the center rod 13 is connected with a nut and limits the maximum spacing distance between the threaded platform 2 and the fixed seat 12.

The first one is as follows: Fig.13 A protruding square rod 14 with a hole is provided in the middle of the bottom of the threaded platform 2, and an inner square hole 15 matching the square rod with a hole is provided in the middle of the fixed seat 12. The square rod 14 with a hole is slidably connected in the inner square hole 15 up and down, so as to achieve the longitudinal and lateral limiting effect of the vibration isolator, and also prevent the relative rotation of the threaded platform 2 and the fixed seat 12. The center rod 13 is located in the hole of the square rod 14 with a hole.

There is a downward pressure gap between the limit groove of the first cylinder structure 18 and the corresponding limit block of the second cylinder structure 19.

[0169] Based on Example 1, the fourth structural form of the threaded platform 2 and the fixed seat 12 to prevent relative rotation, refer to the attached Fig.11 An inner square structure outer sleeve 20 is axially extended corresponding to the bottom of the threaded platform 2, and an outer square structure 21 is provided on the top edge of the fixed seat 12. The outer square structure 21 is adapted to be inserted into and rotate synchronously with the corresponding inner square structure outer sleeve 20, and there is a downward pressure gap between the outer square structure 21 and the corresponding inner square structure outer sleeve 20.

[0170] In order to improve the installation effect and prevent loosening, a locking hole is provided on the inner wall of the adjusting threaded barrel 3, and a locking screw 23 is connected in the locking hole. The locking screw 23 is tightly fixed to the inner wall of the threaded platform 1 to prevent the adjusting threaded barrel from loosening.

[0171] In order to improve the anti-loosening effect, a locking plate 22 is provided on the inner top of the threaded platform 1, and the locking plate 22 abuts against the adjusting threaded tube 3 to prevent the adjusting threaded tube from loosening.

[0172] The elastic buffer abutment platform is a conical platform or a folded platform, the elastic buffer support platform is a conical platform or a flat platform, the elastic buffer 11 is located between the elastic buffer abutment platform and the elastic buffer support platform. Based on the elastic buffer 11 with different configurations, the configurations of the elastic buffer abutment platform and the support platform are reasonably selected to facilitate adaptive installation.

[0173] Specifically, the elastic buffer member 11 is a single spring member or a double spring member or a rubber-steel plate composite member or a composite rubber spring member.

[0174] There are many structural forms of elastic buffers.
