Description

Self-locking fastening bolts for seismic bracing and hangers Technical Field

[0001] This utility model relates to the field of fasteners for seismic bracing and hangers, and particularly to self-locking fastening screws for seismic bracing and hangers. Background Technology

[0002] Seismic bracing is a type of earthquake-resistant facility used in building electromechanical engineering. Its main purpose is to ensure the safety and stability of electromechanical equipment, pipelines, and other systems during vibrations, reducing damage caused by vibrations and protecting life and property. In pipeline seismic bracing, pipe clamps are typically connected to channel steel using bolts, allowing the pipeline to be reliably fixed to the bracing.

[0003] The existing bolt structure for seismic bracing and hangers is relatively simple. When subjected to external vibrations, it is easy for the bolt to loosen with the connecting parts, thus affecting the subsequent connection tightness. In view of this, we propose a self-locking fastening bolt for seismic bracing and hangers. Summary of the Invention

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a self-locking fastening screw for seismic bracing and hangers. This solves the technical problem that the existing screw structure of seismic bracing and hangers for pipelines is relatively simple, and it is easy for it to loosen with the connecting parts when subjected to external vibration, thus affecting the subsequent connection tightness.

[0005] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: a self-locking fastening screw for seismic bracing is designed and applied to seismic bracing of pipelines. The surface of the seismic bracing of the pipeline is provided with pipe clamps. The seismic bracing of the pipeline and the pipe clamps are connected by a set of limiting screws. An auxiliary mechanism is provided at the top inside the limiting screws, and a locking mechanism is provided at the bottom of the auxiliary mechanism.

[0006] The locking mechanism includes a cross bar, which is fixed inside the bottom of the limiting screw. Two sets of sliding plates are evenly fitted on the surface of the cross bar. A spring is provided on the side of the sliding plate away from the middle of the cross bar. A movable block is fixed to the top of the sliding plate. A locking rod is fixed to the side surface of the movable block away from the sliding plate.

[0007] Preferably, the slide plate forms an elastic structure with a spring and a limiting screw, and the slide plate, the movable block, and the locking rod are integrally formed.

[0008] Preferably, the movable block has a right-angled trapezoidal cross-section, the inclined surface of the movable block can fit with the auxiliary mechanism, and the movable block forms a locking and sliding structure with the locking rod and the limiting screw.

[0009] Preferably, the auxiliary mechanism includes a threaded block, which is screwed to the inner side of the top of the limiting screw. A first connecting rod is fixed to the bottom end of the threaded block, and a I-beam is fixed to the bottom end of the first connecting rod. A guide plate is provided on the outer side of the I-beam, and a second connecting rod is fixed to the bottom end of the I-beam. A stop block is fixed to the bottom end of the second connecting rod.

[0010] Preferably, the first connecting rod is fixedly connected to the second connecting rod through an I-beam frame, the I-beam frame can rotate freely inside the guide plate, and the outer wall of the guide plate is in contact with the inner groove wall of the limiting screw.

[0011] Preferably, the abutment block is spherical in shape, and during the downward movement of the abutment block, it gradually pushes against the outward movement of the movable block.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model gradually pushes the two sets of movable blocks outward by moving the abutment block downward. At this time, the end of the locking rod is exposed and effectively fits with the bottom of the pipe seismic support, which plays an extension and limiting role. There is no need to use nuts to tighten again. When the abutment block moves upward and gradually separates from the two sets of movable blocks, the sliding plate effectively drives the movable block and locking rod to move inward due to the spring rebound force, thereby hiding the end of the locking rod inside the limiting screw, releasing the corresponding restriction, and facilitating the subsequent disassembly of the limiting screw.

[0014] 2. This utility model uses a screw-on threaded block to move it downwards and conceal it inside the top of the limiting screw. At the same time, the first connecting rod, the I-beam frame, and the second connecting rod drive the abutment block downwards. The abutment block contacts the locking mechanism, causing part of the locking mechanism to move out, quickly achieving locking between the limiting screw and the pipeline seismic support, preventing the limiting screw from falling off due to external vibration. During subsequent disassembly, the screw-on threaded block is moved upwards, causing the abutment block to move upwards. At this time, the exposed part of the locking mechanism moves inwards, making it easy to disassemble the limiting screw. The guide plate can improve the vertical movement stability of the first connecting rod, the I-beam frame, and the second connecting rod. Attached Figure Description

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0026] Self-locking fastening screws are used for seismic bracing and hangers, as shown in Figures 1 to 7. They are applied to seismic bracing and hangers 1 for pipelines. Pipe clamps 2 are provided on the surface of seismic bracing and hangers 1. Seismic bracing and hangers 1 for pipelines and pipe clamps 2 are connected by a set of limiting screws 3. An auxiliary mechanism 4 is provided at the top inside the limiting screws 3, and a locking mechanism 5 is provided at the bottom of the auxiliary mechanism 4.

[0027] The locking mechanism 5 includes a cross rod 501, which is fixed to the bottom of the limiting screw 3. Two sets of sliding plates 502 are evenly fitted on the surface of the cross rod 501. A spring 503 is provided on the side of the sliding plate 502 away from the middle of the cross rod 501. A movable block 504 is fixed to the top of the sliding plate 502. A locking rod 505 is fixed to the side of the movable block 504 away from the sliding plate 502. The sliding plate 502 and the limiting screw 3 form an elastic structure through the spring 503. The sliding plate 502, the movable block 504, and the locking rod 505 are integrally formed. Furthermore, the cross section of the movable block 504 is a right trapezoid. The inclined surface of the movable block 504 can fit with the auxiliary mechanism 4. The movable block 504 and the limiting screw 3 form a locking and sliding structure through the locking rod 505. This utility model gradually pushes the two sets of movable blocks 504 outward by the downward movement of the abutment block 406. At this time, the end of the locking rod 505 is exposed and effectively fits with the bottom of the pipe anti-seismic support 1, which plays an extension and limiting role. There is no need to use nuts to tighten again. When the abutment block 406 moves upward and gradually separates from the two sets of movable blocks 504, under the influence of the rebound force of the spring 503, the sliding plate 502 effectively drives the movable block 504 and the locking rod 505 to move inward, thereby hiding the end of the locking rod 505 inside the limiting screw 3, releasing the corresponding restriction, and facilitating the subsequent disassembly of the limiting screw 3.

[0028] It is worth noting that the auxiliary mechanism 4 includes a threaded block 401, which is screwed to the inner side of the top of the limiting screw 3. A first connecting rod 402 is fixedly connected to the bottom end of the threaded block 401, and a I-frame 403 is fixedly connected to the bottom end of the first connecting rod 402. A guide plate 404 is provided on the outer side of the I-frame 403, and a second connecting rod 405 is fixedly connected to the bottom end of the I-frame 403. The first connecting rod 402 is fixedly connected to the second connecting rod 405 through the I-frame 403. The I-frame 403 can rotate freely inside the guide plate 404. The outer wall of the guide plate 404 is in contact with the inner groove wall of the limiting screw 3. A stop block 406 is fixedly connected to the bottom end of the second connecting rod 405. Furthermore, the stop block 406 is shaped like a ball cap. During the downward movement of the stop block 406, it gradually pushes the movable block 504 outward. This invention uses a screw-on threaded block 401 to move it downwards and conceal it inside the top of the limiting screw 3. Simultaneously, the first connecting rod 402, the I-beam frame 403, and the second connecting rod 405 drive the abutment block 406 downwards. The abutment block 406 contacts the locking mechanism 5, causing part of the locking mechanism 5 to move out, quickly achieving locking between the limiting screw 3 and the pipe anti-seismic support 1, preventing the limiting screw 3 from falling off due to external vibration. During subsequent disassembly, the screw-on threaded block 401 is moved upwards, causing the abutment block 406 to move upwards. At this time, the exposed part of the locking mechanism 5 moves inwards, making it easy to disassemble the limiting screw 3. The guide plate 404 can improve the vertical movement stability of the first connecting rod 402, the I-beam frame 403, and the second connecting rod 405.

[0029] Working principle: First, the seismic support 1 and pipe clamp 2 are connected by the limiting screw 3. Then, the threaded block 401 is screwed down and concealed inside the top of the limiting screw 3. At the same time, the first connecting rod 402, the I-beam frame 403, and the second connecting rod 405 drive the abutment block 406 to move down. The downward movement of the abutment block 406 gradually pushes the two sets of movable blocks 504 outward. At this time, the end of the locking rod 505 is exposed and fits against the bottom of the seismic support 1, which plays an extended limiting role. There is no need to use the nut again. The fastening mechanism quickly locks the limit screw 3 to the pipe seismic support 1, preventing external vibrations from causing the limit screw 3 to fall off. Subsequently, the threaded block 401 is screwed upward, which in turn moves the abutment block 406 upward. As the abutment block 406 moves upward, it gradually separates from the two sets of movable blocks 504. Under the influence of the spring 503's rebound force, the sliding plate 502 moves the movable block 504 and the locking rod 505 inward, thereby concealing the end of the locking rod 505 inside the limit screw 3, releasing the corresponding restriction, and facilitating the subsequent disassembly of the limit screw 3.

Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
