Description

Technical Field

[0001] This utility model relates to the field of seismic bracing technology, and more specifically, to an adjustment mechanism for seismic bracing. Background Technology

[0002] In the field of pipeline installation and equipment fixing, seismic measures have become a key link in ensuring structural safety, especially in high-rise buildings and important infrastructure in earthquake-prone areas. The need for precise height adjustment of support devices is particularly urgent. It is often necessary to make fine adjustments to the height of various pipelines according to the actual situation to adapt to different space constraints and load requirements. However, traditional adjustment methods usually rely on bolt fastening or complex locking devices. Operators need to carry a variety of tools and perform tedious adjustment and fixing operations in a limited space. This not only consumes a lot of manpower and time, but also makes it difficult to ensure the accuracy of adjustment, reducing construction efficiency and installation quality.

[0003] Existing support adjustment systems mostly use traditional mechanical locking methods, which require workers to perform multiple steps using wrenches or other special tools. This not only increases the danger of working at heights, but also makes the support prone to loosening or displacement under earthquake or vibration conditions due to insufficient tightening. At the same time, the repeated tightening and loosening during the frequent adjustment process also accelerates the wear of threads and connecting parts, reducing the service life and reliability of the entire support system. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In view of the problems existing in the prior art, this utility model provides an adjustment mechanism for an anti-seismic brace to solve the technical problems mentioned in the background art.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: an adjustment mechanism for an anti-seismic brace, comprising a support plate, an adjustment assembly on the support plate, the adjustment assembly comprising an adjustment frame, an adjustment rod, an adjustment hole, and a plug, the adjustment frame being fixed on both sides of the support plate, the adjustment rod sliding within multiple sets of adjustment frames, multiple sets of adjustment holes distributed on the outer walls of multiple sets of adjustment rods, the plug being inserted into the adjustment hole, a fixing assembly being provided on the outer side of the adjustment frame, the fixing assembly comprising a fixing sleeve, a snap-fit ​​rod, a movable groove, a snap block, a push spring, and a snap ring, the fixing sleeve being fixed on the outer wall of the adjustment frame, the snap-fit ​​rod being fixed on the top of the plug, multiple sets of movable grooves distributed on the outer walls of the snap-fit ​​rods, the snap block sliding within multiple sets of movable grooves, multiple sets of push springs respectively connected to the inner walls of the movable grooves and respectively connected to the inner walls of multiple sets of snap blocks, the snap ring being fixed on the inner wall of the fixing sleeve, and a clamping assembly being provided on the support plate.

[0008] The present invention is further configured such that the inner side of the retaining ring is set as an inclined surface, and the top of the multiple sets of retaining blocks are all set as inclined surfaces. This double inclined surface design forms a guide structure, which allows the retaining blocks to slide smoothly and compress the push spring during insertion, reducing insertion resistance and improving the convenience and smoothness of locking operation.

[0009] The present invention is further provided that the outer walls of the retaining ring and the retaining block are provided with rounded corners. The rounded corner design reduces the friction and jamming risk between the components, makes the contact of the moving parts smoother, extends the service life of the components, and at the same time reduces the operating resistance and improves the sensitivity and response speed of the overall mechanism.

[0010] The present invention is further configured such that the outer wall of the fixed sleeve is provided with a sliding groove, a sliding sleeve is slidably arranged in multiple sets of the sliding groove, a push sleeve is fixedly arranged on the inner side of the sliding sleeve, and a threaded sleeve is threadedly connected to the outer wall of the fixed sleeve. The top surface of the threaded sleeve is rotatably connected to the sliding sleeve. This spiral drive unlocking structure converts rotational motion into linear thrust, so that the operator only needs to rotate the threaded sleeve to generate sufficient force to push the locking block. The unlocking operation can be easily completed without the aid of external tools, which greatly improves work efficiency and safety.

[0011] The present invention is further configured such that the clamping assembly includes a base, a screw, a transmission block, and a clamping plate. The base is fixed on the top surface of the support plate, the screw rotates on the base, the transmission block is provided with multiple sets of threaded connections to both ends of the screw, and the clamping plate is fixed to the inner side of the multiple sets of transmission blocks respectively. This transmission structure enables the clamping plate to accurately clamp the pipe and evenly distribute the pressure, avoiding local stress concentration that could cause pipe deformation. At the same time, it simplifies the operation process, as the pipe can be quickly clamped and released simply by rotating the screw.

[0012] The present invention is further configured such that a slide rail is fixedly provided on the base, and a slide seat is fixedly provided on the bottom surface of multiple sets of transmission blocks. The slide seats are slidably connected to the slide rail. The guiding design of the slide rail and the slide seat ensures that the transmission blocks move only along the axial direction without deflection, ensuring accurate alignment and parallel clamping of the clamping plate and the pipe, and improving the stability and shock resistance of the clamping.

[0013] The present invention is further configured such that the screw is a double-ended screw, and multiple sets of transmission blocks are respectively threaded to both ends of the screw. The double-ended screw structure enables the transmission blocks on both sides to move synchronously toward or away from the center, ensuring the symmetrical distribution and balance of the clamping force, improving the stability and reliability of clamping, and adapting to the clamping requirements of pipes of different diameters.

[0014] The present invention is further provided that a throttle is fixedly provided at one end of the screw. The throttle provides a convenient manual operation interface, increases the operating torque, reduces the labor intensity of the operator, and makes the adjustment operation easier and faster, especially suitable for operation in confined spaces or high-altitude working environments.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides an adjustment mechanism for an anti-seismic brace, which has the following advantages:

[0017] 1. The adjustment component, through the combination design of support plate and adjustment frame, together with adjustment rod and multiple evenly distributed adjustment holes, constructs a flexible and precise height adjustment system, enabling the seismic bracing to be quickly adjusted in height according to different installation environments and space constraints. At the same time, the design of the plug cleverly solves the problem of traditional brackets requiring cumbersome tool operation, greatly simplifies the adjustment steps in the construction process, and improves installation efficiency. It is particularly suitable for seismic bracing systems in high-rise buildings and important infrastructure that require frequent and precise adjustments.

[0018] 2. The fixing component adopts a combination structure of fixing sleeve and snap-fit ​​rod. Through the self-locking mechanism of snap-fit ​​block and push spring in the movable groove, a tool-free quick locking function is achieved. The beveled design of the inner side of the snap ring and the top of the snap-fit ​​block makes the locking process smoother, while the rounded corners of the push block and snap-fit ​​block reduce operating resistance. The ingenious cooperation of the sliding groove, sliding sleeve and threaded sleeve provides a convenient unlocking method. The operator only needs to rotate the threaded sleeve to unlock. This intelligent design not only improves the safety of high-altitude operations, but also greatly enhances the stability and reliability of the entire support system under earthquake or vibration conditions.

[0019] 3. The clamping assembly, through the stable connection between the base and the screw, combined with the precise cooperation between the transmission block and the clamping plate, constructs a highly efficient and reliable pipe clamping system. The double-headed screw design allows the clamping plates on both sides to move synchronously towards the center, ensuring a uniform distribution of clamping force. The throttle provides a convenient operating method, while the cooperation between the slide rail and the slide block ensures the smooth and precise movement of the clamping plates. This integrated clamping structure greatly enhances the connection stability between the seismic support and the pipe, effectively preventing the pipe from shaking and falling off under earthquake conditions. It also facilitates daily maintenance and replacement work, improving the applicability and service life of the entire seismic system. Attached Figure Description

[0027] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0029] Please see Figures 1-5 An adjustment mechanism for a seismic bracing system includes a support plate 1. The support plate 1 is equipped with an adjustment assembly comprising an adjustment frame 2, an adjustment rod 3, adjustment holes 4, and a bolt 5. The adjustment frame 2 is fixed to both sides of the support plate 1. The adjustment rod 3 slides within multiple sets of adjustment frames 2. Multiple sets of adjustment holes 4 are distributed on the outer walls of the multiple sets of adjustment rods 3. The bolt 5 is inserted into the adjustment holes 4. A fixing assembly is provided on the outer side of the adjustment frame 2. The fixing assembly includes a fixing sleeve 6, a snap-fit ​​rod 7, a movable groove 8, a locking block 9, a push spring 10, and a retaining ring 11. The fixing sleeve 6 is fixed to the outer wall of the adjustment frame 2. The snap-fit ​​rod 7 is fixed to the top of the bolt 5. Multiple sets of movable grooves 8 are distributed on the outer wall of the snap-fit ​​rod 7. The locking block 9 slides within multiple sets of movable grooves 8. Multiple sets of push springs 10 are respectively connected to the inner walls of the movable grooves 8 and respectively connected to the inner walls of the multiple sets of locking blocks 9. The retaining ring 11 is fixed to the inner wall of the fixing sleeve 6. A clamping assembly is provided on the support plate 1.

[0030] The inner side of the retaining ring 11 is set as an inclined surface, and the top of the multiple sets of retaining blocks 9 are also set as inclined surfaces. When the retaining rod is inserted into the fixing sleeve 6, the inclined surface at the top of the retaining block 9 first contacts the inclined surface on the inner side of the retaining ring 11. The two inclined surfaces slide against each other to generate radial thrust, which forces the retaining block 9 to compress the push spring inward, so that the retaining block 9 can pass smoothly through the restriction area of ​​the retaining ring 11. Once it has passed completely, the push spring releases energy to push the retaining block 9 to reset, forming a mechanical lock with the retaining ring 11.

[0031] Both the retaining ring 11 and the retaining block 9 have rounded corners on their outer walls. The rounded corner structure eliminates the jamming and wear that may be caused by sharp edges, allowing the push block to slide more smoothly when pushing the retaining block 9. It also reduces the concentration of contact stress between components, extends the service life of the mechanism, and improves the reliability and smoothness of locking and unlocking operations.

[0032] The outer wall of the fixed sleeve 6 is provided with a sliding groove 12, and a sliding sleeve 13 is slidably arranged in multiple sets of sliding grooves 12. A push sleeve 14 is fixedly arranged on the inner side of the sliding sleeve 13. A threaded sleeve 15 is threadedly connected to the outer wall of the fixed sleeve 6. The top surface of the threaded sleeve 15 is rotatably connected to the sliding sleeve 13. By rotating the threaded sleeve 15, the rotational motion is converted into the linear motion of the sliding sleeve 13 by utilizing the mechanical advantage of the thread. The sliding sleeve 13 applies a precise pushing force to the locking block 9 through the push sleeve 14, causing it to overcome the elasticity of the push spring and retract inward, thereby releasing the locking state with the retaining ring 11, realizing a labor-saving and reliable unlocking operation.

[0033] In this embodiment, when the height of the support plate 1 needs to be adjusted, the adjusting bracket 2 slides along the adjusting rod 3. After the support plate 1 moves to a suitable height, the adjusting hole 4 is aligned with the fixing sleeve 6, and then the bolt 5 is inserted into the adjusting hole 4. At the same time, the locking rod 7 is inserted into the fixing sleeve 6. The inclined surface on the inner side of the retaining ring 11 pushes the locking block 9 to slide into the movable groove 8 and compresses the multiple sets of push springs 10. When the multiple sets of locking blocks 9 are completely inside the fixing sleeve 6, they disengage from the inner side of the retaining ring 11, and the multiple sets of push springs 10 push the locking block 9 out of the movable groove 8. When the bottom surface of the multiple sets of locking blocks 9 abuts against the top surface of the locking ring 11, the adjustment frame 2 is fixed. When unlocking is required, the threaded sleeve 15 is rotated and threadedly connected to the outer wall of the fixed sleeve 6, so that the threaded sleeve 15 drives the sliding sleeve 13 to slide along the multiple sets of sliding grooves 12. The sliding sleeve 13 drives the push sleeve 14 to abut against the inclined surface set at the top of the multiple sets of locking blocks 9, thereby pushing the multiple sets of locking blocks 9 to slide in the movable groove 8 and releasing their bottom ends from the locking ring 11. Then the locking rod 7 can be pulled out of the fixed sleeve 6, and at the same time, the plug 5 is disengaged from the adjustment hole 4, thus unlocking the adjustment frame 2.

[0034] Please see Figure 5As one implementation of the clamping assembly: the clamping assembly includes a base 16, a screw 17, a transmission block 18, and a clamping plate 19. The base 16 is fixed to the top surface of the support plate 1, the screw 17 rotates on the base 16, the transmission block 18 is provided with multiple sets of threaded connections to both ends of the screw 17, and the clamping plate 19 is fixed to the inner side of the multiple sets of transmission blocks 18 respectively. The base 16 is fixed to the support plate 1 as a stable support. When the screw 17 rotates, the rotational motion is converted into the linear motion of the transmission block 18 through the threaded transmission. The transmission blocks 18 on both sides drive the clamping plate 19 to move towards the center or away from it at the same time, forming a uniform clamping or release of the pipe, ensuring the symmetrical distribution and stability of the clamping force.

[0035] A slide rail 20 is fixedly mounted on the base 16, and multiple sets of transmission blocks 18 are each fixedly mounted with a slide seat 21 on their bottom surface. The slide seats 21 are slidably connected to the slide rail 20. The slide rail 20 and the slide seat 21 form a precise linear motion constraint, ensuring that the transmission block 18 can only move along the predetermined axial path without deflection or shaking. This improves the accuracy and stability of the clamping process, while also reducing the lateral load on the screw 17, extending the service life and operational reliability of the entire mechanism.

[0036] The screw 17 is configured as a double-ended screw 17, and multiple sets of transmission blocks 18 are threadedly connected to both ends of the screw 17. The two ends of the screw 17 use threads in opposite directions. When the screw 17 rotates, the transmission blocks 18 on both sides will move towards or away from the center simultaneously according to the direction of their respective threads, so that a single rotation action can simultaneously control the movement of the two clamping plates 19, achieving a symmetrical and balanced clamping force distribution and simplifying operation.

[0037] A handle 22 is fixedly provided at one end of the screw 17. The handle 22 provides a contact interface for easy manual operation, increases the operating lever arm length, and allows the operator to generate sufficient torque with less force to drive the screw 17 to rotate. It also provides an intuitive operation method, allowing clamping and releasing operations to be completed without special tools, thus improving ease of use and on-site adaptability.

[0038] More specifically, the pipe is placed between multiple sets of clamping plates 19, and the throttle 22 is turned to drive the screw 17 to rotate. The screw 17 is threadedly engaged with multiple sets of transmission blocks 18 through different threads at both ends, so that the multiple sets of transmission blocks 18 push the clamping plates 19 to clamp and fix the pipe on the outer wall. When the transmission sleeve moves, it slides through the slider and the slide rail 20.

[0039] In summary, during the use or operation of the overall equipment: when the height of the support plate 1 needs to be adjusted, the adjusting frame 2 slides along the adjusting rod 3. After the support plate 1 moves to the appropriate height, the adjusting hole 4 is aligned with the fixing sleeve 6. Then, the bolt 5 is inserted into the adjusting hole 4, and the locking rod 7 is inserted into the fixing sleeve 6. The inclined surface on the inner side of the retaining ring 11 pushes the locking block 9 to slide into the movable groove 8 and compresses the multiple sets of push springs 10. When the multiple sets of locking blocks 9 are completely inside the fixing sleeve 6, they disengage from the inner side of the retaining ring 11, and the multiple sets of push springs 10 push the locking block 9 to slide out of the movable groove 8. In groove 8, the bottom surfaces of multiple sets of locking blocks 9 abut against the top surface of the retaining ring 11, thereby fixing the adjusting frame 2. When unlocking is required, the threaded sleeve 15 is rotated to connect with the outer wall of the fixed sleeve 6, so that the threaded sleeve 15 drives the sliding sleeve 13 to slide along multiple sets of sliding grooves 12. The sliding sleeve 13 drives the push sleeve 14 to abut against the inclined surface set at the top of the multiple sets of locking blocks 9, thereby pushing the multiple sets of locking blocks 9 to slide in the movable groove 8 and releasing their bottom ends from the retaining ring 11. Then the locking rod 7 can be pulled out of the fixed sleeve 6, and at the same time, the plug 5 is disengaged from the adjusting hole 4, thus unlocking the adjusting frame 2.

[0040] The pipe is placed between multiple sets of clamping plates 19. The throttle 22 is turned to drive the screw 17 to rotate. The screw 17 is threaded with multiple sets of transmission blocks 18 through different threads at both ends, so that the multiple sets of transmission blocks 18 push the clamping plates 19 to clamp the pipe on the outer wall and fix the pipe. When the transmission sleeve moves, it slides with the slide rail 20 through the slider.

[0041] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model.
