Description
Technical Field
[0001] This utility model relates to the technical field of anti-cracking devices, specifically an anti-cracking device for repairing wooden components of ancient buildings. Background Technology
[0002] In the field of ancient building conservation and restoration, wooden components, as an important part of the structure of ancient buildings, are of paramount importance in terms of their integrity and stability. However, due to the age of ancient buildings, wooden components often suffer from cracking and damage due to natural environmental erosion, insect infestation, and other factors. Therefore, effective restoration devices are needed to protect and reinforce them.
[0003] Existing restoration devices for ancient building wooden components have shortcomings in structural design and ease of use. On the one hand, unlocking and locking operations often require manual operation with the help of various tools, which is cumbersome, time-consuming, and inefficient. On the other hand, during the locking process, it is difficult to precisely control the rotation force and number of turns, which can easily lead to uneven locking force, loosening of the protective plate, and failure to effectively protect the ancient building wooden components and prevent them from cracking. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a device for repairing and preventing cracking of wooden components in ancient buildings. This device solves the technical problem that during the locking process, it is difficult to accurately control the rotation force and number of turns, which can easily lead to uneven locking force, loosening of the protective plate, and failure to effectively protect the wooden components of ancient buildings and prevent them from cracking.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a device for repairing and preventing cracking of wooden components in ancient buildings, comprising: a protective plate, a hinge, and a reinforcing arm, wherein the hinge and the reinforcing arm are both disposed outside the protective plate, and a locking plate is disposed outside the protective plate, and a threaded rod and a locking mechanism are respectively disposed between two sets of opposing locking plates; First, remove the threaded rod from the outside of the locking plate, then place the protective plate on the outside of the ancient building's wooden components. Next, insert the threaded rod into the inside of the locking mechanism, and place the socket of the electric wrench on the outside of the locking mechanism. The socket presses the trapezoidal block to move, and then drives the locking arm to lift from the inside of the slot through the connecting rod, releasing the nut from its fixation. The operation is simple and can quickly unlock the nut, providing convenience for subsequent locking operations of the device, reducing operation time, and improving work efficiency. The nut is rotated by an electric wrench, which in turn drives the threaded rod to lock the locking plate and the protective plate. The electric wrench drives the nut to rotate, which can precisely control the force and number of rotations, ensuring that the locking force of the threaded rod on the locking plate and the protective plate is uniform and appropriate. This effectively prevents the protective plate from loosening due to uneven or insufficient locking force, thus better protecting the wooden components of ancient buildings and preventing them from cracking. After locking, the sleeve disengages from the nut, the trapezoidal block returns to its original position via the spring, and the locking arm continues to insert into the slot to lock the nut's position. The spring's rebound force allows the trapezoidal block to quickly reset, thereby driving the locking arm to quickly insert into the slot, reliably locking the nut's position and preventing the nut from loosening due to vibration or other reasons during the use of the device. This ensures the long-term effectiveness of the entire device in protecting ancient wooden building components. The locking mechanism includes a nut, a trapezoidal block and a locking arm are slidably connected to the inner cavity of the nut, a connecting rod is rotatably connected to the outside of the trapezoidal block, the other end of the connecting rod is rotatably connected to the locking arm, a locking groove adapted to the locking arm is opened on the outside of the locking plate, and a spring is provided on the outside of the trapezoidal block, the other end of the spring is connected to the inner cavity of the nut.
[0006] Preferably, the nut has a T-shaped groove inside, and the inner cavity of the T-shaped groove has a track groove. A track block is slidably connected inside the track groove, and the track block is slidably connected to the trapezoidal block and the locking arm. The T-shaped groove, as well as the internal track groove and track block, provide precise guidance for the sliding of the trapezoidal block and the locking arm, ensuring that the trapezoidal block and the locking arm always move along a predetermined trajectory during movement, avoiding deviation or jamming. This guarantees the accuracy and stability of the cooperation between the components of the locking mechanism, thereby improving the overall reliability of the device.
[0007] Preferably, the trapezoidal block is provided with reinforcing ribs on its exterior. These ribs enhance the structural strength of the trapezoidal block, making it less prone to deformation or damage when subjected to large compressive forces from the sleeve. This ensures that the trapezoidal block can stably transmit force, driving the locking arm to move normally via the connecting rod and maintaining the normal working state of the locking mechanism. The top of the trapezoidal block is designed with a slope. This sloped design allows the sleeve to more smoothly convert the vertical force into a force that propels the trapezoidal block to move horizontally when it compresses the block. This reduces energy loss during force transmission, lowers the difficulty of operation, and improves ease of operation.
[0008] Preferably, the bottom of the clamping arm is designed with rounded corners. This rounded corner design reduces friction with the edge of the clamping slot during insertion and removal, resulting in smoother movement of the clamping arm and preventing wear or jamming due to excessive friction. It also reduces operational resistance and improves operational fluidity. The clamping arm is externally fitted with a wear-resistant pad. This pad effectively reduces direct contact and friction between the clamping arm and the slot during repeated insertion and removal, reducing wear, extending service life, and ensuring the precise fit between the clamping arm and the slot. This, in turn, ensures a long-lasting and stable locking effect of the locking mechanism on the nut.
[0009] Preferably, at least six sets of trapezoidal blocks are provided, each set on the outside of the nut. Providing at least six sets of trapezoidal blocks allows for simultaneous locking of the nut from multiple directions, increasing the stability and reliability of the nut locking mechanism. This ensures that the nut remains fixed in position under external forces from different directions through the coordinated action of the multiple sets of trapezoidal blocks and the locking arms, preventing loosening and better protecting the wooden components of the ancient building.
[0010] Preferably, a bearing is provided at the bottom of the nut, and the bearing is located outside the locking plate. The bearing allows the nut to rotate more smoothly, reduces the frictional resistance between the nut and the locking plate, reduces energy loss, and also improves the rotation accuracy of the nut. This ensures that the threaded rod can accurately drive the locking plate and the protective plate to perform the locking operation, making the device more reliable in protecting the wooden components of ancient buildings.
[0011] Compared with the prior art, this utility model provides a device for repairing and preventing cracking of wooden components in ancient buildings, which has the following beneficial effects: This anti-cracking device for repairing ancient wooden components involves first removing the threaded rod from the outside of the locking plate, then placing the protective plate over the outside of the wooden component. Next, the threaded rod is inserted, and an electric wrench is used to press the trapezoidal block against the locking mechanism. A connecting rod drives the locking arm to lift from the slot, releasing the nut and allowing for quick unlocking. This facilitates subsequent tightening operations, reduces time, and improves efficiency. During tightening, the electric wrench drives the nut to rotate, which in turn tightens the threaded rod against the locking plate and protective plate. Precise control of the rotation force and number of turns ensures even and appropriate tightening force, effectively preventing the protective plate from loosening and better protecting the ancient wooden components from cracking. After tightening, the sleeve disengages from the nut, and the trapezoidal block quickly resets under the spring's rebound force, causing the locking arm to quickly insert into the slot, reliably locking the nut in place. This prevents the nut from loosening due to vibration or other factors during device use, ensuring the long-term effectiveness of the device in protecting the ancient wooden components.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] This utility model provides a technical solution, please refer to Figure 1 , Figure 2 and Figure 3 A device for repairing and preventing cracking of wooden components in ancient buildings includes: a protective plate 1, a hinge 11 and a reinforcing arm 2. The hinge 11 and the reinforcing arm 2 are both located outside the protective plate 1. A locking plate 3 is provided outside the protective plate 1. A threaded rod 4 and a locking mechanism 5 are respectively provided between two sets of opposing locking plates 3. First, remove the threaded rod 4 from the outside of the locking plate 3, then put the protective plate 1 on the outside of the ancient building wooden component. Next, insert the threaded rod 4 into the inside of the locking mechanism 5, and put the sleeve of the electric wrench on the outside of the locking mechanism 5. The sleeve squeezes the trapezoidal block 52 to move, and then drives the locking arm 54 to lift from the inside of the slot through the connecting rod 53, thereby releasing the fixing of the nut 51. The operation is simple and can quickly unlock the nut 51, which provides convenience for the subsequent locking operation of the device, reduces the operation time, and improves the work efficiency. The nut 51 is rotated by an electric wrench, which in turn drives the threaded rod 4 to lock the locking plate 3 and the protective plate 1. The rotation of the nut 51 by the electric wrench can precisely control the force and number of rotations, ensuring that the locking force of the threaded rod 4 on the locking plate 3 and the protective plate 1 is uniform and appropriate. This effectively prevents the protective plate 1 from loosening due to uneven or insufficient locking force, thereby better protecting the wooden components of the ancient building and preventing them from cracking. After locking, the sleeve disengages from the nut 51, the trapezoidal block 52 returns to its original position via the spring 55, and the locking arm 54 continues to insert into the slot to lock the position of the nut 51. The rebound force of the spring 55 enables the trapezoidal block 52 to quickly return to its original position, thereby driving the locking arm 54 to quickly insert into the slot, reliably locking the position of the nut 51 and preventing the nut 51 from loosening due to vibration or other reasons during the use of the device, thus ensuring the long-term effectiveness of the entire device in protecting the wooden components of ancient buildings. The locking mechanism 5 includes a nut 51, with a trapezoidal block 52 and a locking arm 54 slidably connected to the inner cavity of the nut 51. A connecting rod 53 is rotatably connected to the outside of the trapezoidal block 52, and the other end of the connecting rod 53 is rotatably connected to the locking arm 54. A locking groove adapted to the locking arm 54 is opened on the outside of the locking plate 3. A spring 55 is provided on the outside of the trapezoidal block 52, and the other end of the spring 55 is connected to the inner cavity of the nut 51.
[0016] The nut 51 has a T-shaped groove 57 inside, and a track groove is formed inside the T-shaped groove 57. A track block is slidably connected inside the track groove, and the track block is slidably connected to the trapezoidal block 52 and the locking arm 54. The T-shaped groove 57, as well as the internal track groove and track block, provide precise guidance for the sliding of the trapezoidal block 52 and the locking arm 54, so that the trapezoidal block 52 and the locking arm 54 always move along the predetermined trajectory during the movement, avoiding deviation or jamming. This ensures the accuracy and stability of the cooperation between the components of the locking mechanism 5, thereby improving the overall reliability of the device.
[0017] The trapezoidal block 52 is reinforced with external ribs, which enhance its structural strength, making it less prone to deformation or damage when subjected to large compressive forces from the sleeve. This ensures that the trapezoidal block 52 can stably transmit force, driving the locking arm 54 to move normally via the connecting rod 53, maintaining the normal working state of the locking mechanism 5. The top of the trapezoidal block 52 is designed with a slope. This sloped design allows the sleeve to more smoothly convert vertical force into a force that propels the trapezoidal block 52 horizontally when it compresses it, reducing energy loss during force transmission, simplifying operation, and improving ease of use.
[0018] The bottom of the locking arm 54 is designed with rounded corners. This rounded corner design reduces friction with the edge of the slot during insertion and removal, making the movement of the locking arm 54 smoother and preventing wear or jamming due to excessive friction. It also reduces operational resistance and improves operational fluidity. The locking arm 54 is equipped with a wear-resistant pad. This pad effectively reduces direct contact and friction between the locking arm 54 and the slot during repeated insertion and removal, reducing wear, extending its service life, and ensuring the precision of the fit between the locking arm 54 and the slot. This, in turn, ensures a long-lasting and stable locking effect of the locking mechanism 5 on the nut 51.
[0019] At least six sets of trapezoidal blocks 52 are provided, each located on the outside of the nut 51. The presence of at least six sets of trapezoidal blocks 52 allows for simultaneous locking of the nut 51 from multiple directions, increasing the stability and reliability of the locking mechanism. This ensures that the nut 51 remains fixed in position under external forces from different directions through the coordinated action of the multiple sets of trapezoidal blocks 52 and the locking arms 54, preventing loosening and better protecting the wooden components of the ancient building.
[0020] A bearing 56 is provided at the bottom of the nut 51, and the bearing 56 is located on the outside of the locking plate 3. The bearing 56 makes the nut 51 rotate more smoothly, reduces the frictional resistance between the nut 51 and the locking plate 3, reduces energy loss, and also improves the rotation accuracy of the nut 51. This ensures that the threaded rod 4 can accurately drive the locking plate 3 and the protective plate 1 to perform the locking operation, making the device more reliable in protecting the wooden components of ancient buildings.
[0021] This solution first removes the threaded rod 4 from the outside of the locking plate 3, then places the protective plate 1 on the outside of the ancient building's wooden components. Next, the threaded rod 4 is inserted into the inside of the locking mechanism 5. The sleeve of the electric wrench is then placed on the outside of the locking mechanism 5. The sleeve presses the trapezoidal block 52 to move, and then drives the locking arm 54 to lift from the inside of the slot through the connecting rod 53, releasing the fixing of the nut 51. The electric wrench drives the nut 51 to rotate, which in turn drives the threaded rod 4 to lock the locking plate 3 and the protective plate 1. After locking, the sleeve disengages from the nut 51, the trapezoidal block 52 returns to its original position through the spring 55, and the locking arm 54 continues to be inserted into the slot to lock the position of the nut 51.
