Description

Technical Field

[0001] This utility model relates to the field of fixing device technology, specifically to a fixing device for cultural relic restoration. Background Technology

[0002] With the increasing awareness of cultural heritage protection, the restoration of cultural relics has become increasingly important in museums, archaeological research, and other fields. Among these, ceramic jars, due to their age, often suffer from cracks, missing pieces, and dust accumulation. To ensure the quality of restoration and the restoration of the original appearance, restorers must stably fix the ceramic jars during the restoration process. Failure to reliably fix them during restoration will not only affect the bonding effect but may also cause shaking during cleaning and polishing, leading to restoration failure or further damage.

[0003] However, ceramic jars are difficult to fix in place during actual restoration due to their varying sizes and curved surfaces. Traditional methods often involve manual support, sandbags, or simple clamps. These methods are often ineffective when dealing with ceramic jars of different sizes, as the clamps do not easily conform to the surface, resulting in a lack of stable fixation. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this utility model is to provide a fixing device for cultural relic restoration, so as to solve the problems mentioned in the background art.

Detailed Implementation

[0021] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative of this utility model and are not intended to limit it.

[0022] The following is in conjunction with the appendix Figures 1-4 This embodiment will be described in further detail.

[0023] Please see Figures 1-4 This embodiment of a fixing device for cultural relic restoration includes a table 100, a rotatable support column 101 on the table 100, a disc 102 on the support column 101, a liftable support bar 103 opposite to the disc 102, a telescopic rod 104 opposite to the support bar 103, a universal ball 105 near the end of the rod 104 near the disc 102, a connecting rod 106 on the universal ball 105, an adhesive block 107 for adhering to the surface of a ceramic jar on the connecting rod 106, a driving assembly for driving the support bar 103 to rise and fall below the disc 102, and a telescopic assembly for driving the rod 104 to extend and retract on the support bar 103.

[0024] In actual use, the lower end surface of the platform 100 is provided with a motor 108 for driving the support column 101 to rotate.

[0025] In this embodiment, the disc 102 is provided with a fixing plate 109 for placing the ceramic jar. The fixing plate 109 is fixedly connected to the disc 102. The support column 101 is mounted on the table 100 through bearings. The motor 108 is fixedly mounted on the lower end surface of the table 100. The disc 102 is fixedly connected to the support column 101. The motor 108 can drive the support column 101 to rotate, thereby driving the disc 102 to rotate, so that the ceramic jar placed on the fixing plate 109 can rotate. This allows the ceramic jar to rotate when it is fixed, making it convenient for workers to repair or clean the ceramic jar.

[0026] In this embodiment, the universal ball 105 is installed on one end of the rod 104, and one end of the connecting rod 106 is fixedly connected to the surface of the universal ball 105. The bonding block 107 is fixed to the other end of the connecting rod 106. When fixing the ceramic jar, the ceramic jar is first placed on the fixing plate 109. The telescopic component first moves one rod 104 toward the surface of the ceramic jar. When the bonding block 107 is close to the surface of the ceramic jar, the universal ball 105 can be rotated to adjust the bonding block 107 to the angle that can be bonded to the surface of the ceramic jar. Then, while holding the bonding block 107, the telescopic component continues to move the rod 104 toward the surface of the ceramic jar until the bonding block 107 is completely bonded to the surface of the ceramic jar. Then, the opposite bonding block 107 is manipulated to bond with the surface of the ceramic jar to initially fix the ceramic jar. Finally, the telescopic component is used to manipulate the other two bonding blocks 107 to bond with the surface of the ceramic jar to complete the complete fixation of the ceramic jar. After fixing, the ceramic jar can be repaired.

[0027] In this embodiment, the support bar 103 can be raised and lowered by the drive component, thereby adjusting the height of the bonding block 107. At the same time, the angle of the bonding block 107 can be adjusted, so that the fixing device can fix ceramic jars of different sizes.

[0028] In this embodiment, when fixing the ceramic jar, the bonding block 107 can be raised and lowered by the drive component according to the height of the ceramic jar and the part that needs to be repaired, so that the bonding block 107 is clamped in a suitable part of the ceramic jar, avoiding the bonding block 107 being clamped in the part of the ceramic jar that needs to be repaired, which would affect the repair of the ceramic jar.

[0029] When cleaning the ceramic jar, first adjust the height of the bonding block 107 so that it clamps and fixes the lower half of the ceramic jar. After fixing, clean the upper half of the ceramic jar first. After cleaning the upper half, adjust the height of the bonding block 107 again so that it clamps and fixes the upper half of the ceramic jar. After fixing, clean the lower half of the ceramic jar.

[0030] In this embodiment, the surface of the bonding block 107 that is bonded to the ceramic jar is provided with a sponge or rubber pad to avoid damage to the ceramic jar when the bonding block 107 is clamped.

[0031] In this embodiment, the four bonding blocks 107 can effectively prevent the ceramic jar from tipping over during repair, thereby improving the stable fixing effect of the ceramic jar during repair.

[0032] Please see Figures 1-4In this embodiment, the driving component includes a vertical rod 200 disposed on the disk 102. The side of the vertical rod 200 is provided with a rotatable lead screw 201. The bottom end of the lead screw 201 extends to the bottom of the disk 102. The side of the vertical rod 200 is provided with a limiting groove. The lead screw 201 is provided with a lifting ring 202. The surface of the lifting ring 202 is provided with a limiting rod 203 extending into the limiting groove. The surface of the lifting ring 202 is provided with a round rod 204 connected to the support bar 103.

[0033] The surface of the support column 101 is provided with a fixing frame 205. The fixing frame 205 is provided with a rotating rod 206 that passes through the support column 101 and can rotate. The bottom end of the lead screw 201 is provided with a driven bevel gear 207. The rotating rod 206 is provided with a driving bevel gear 208 that meshes with the driven bevel gear 207.

[0034] In this embodiment, the lower end of the upright 200 is fixedly connected to the disc 102, the lead screw 201 is mounted on the disc 102 through bearings, the lifting ring 202 is threadedly connected to the lead screw 201, one end of the limiting rod 203 is fixedly connected to the lifting ring 202, and the other end of the limiting rod 203 is slidably installed in the limiting groove. The two ends of the support bar 103 are fixedly connected to the lifting ring 202 and the support bar 103 respectively. The fixed frame 205 is fixedly connected to the support column 101. The rotating rod 206 is mounted on the fixed frame 205 through bearings. By rotating the rotating rod 206, the driving bevel gear 208 is driven to rotate, which in turn drives the driven bevel gear 207 to rotate, thereby driving the lead screw 201 to rotate. The rotation of the lead screw 201 can drive the lifting ring 202 to rotate, thereby adjusting the height of the mating block 107.

[0035] Please see Figures 1-4 In this embodiment, the telescopic component includes a column 300 disposed on the support bar 103. The column 300 has a circular cavity for mounting the rod 104. The end of the rod 104 located in the circular cavity has a circular block 301. A spring 302 is sleeved on the rod 104 between the bottom wall of the circular cavity and the circular block 301. The circular cavity is open. A plug 303 is provided at the open end of the circular cavity. The plug 303 has a threaded rod 304 extending into the circular cavity.

[0036] In this embodiment, the support bar 103 has a hole, the column 300 is fixedly connected in the hole, the round block 301 is fixedly connected to the rod 104, the round block 301 can slide in the round cavity, and the plug cap 303 is fixedly installed at the opening end of the round cavity so as to install the components in the round cavity.

[0037] The threaded rod 304 is threadedly connected to the plug cap 303, and the rod body 104 is fixedly connected to the bonding block 107. The spring 302 pushes the round block 301 to move, which drives the rod body 104 away from the ceramic jar. When the control rod 104 moves toward the ceramic jar, the threaded rod 304 can be rotated, which drives the threaded rod 304 to move continuously into the round cavity, squeezing the round block 301 to compress the spring 302, which can drive the bonding block 107 to adhere to the surface of the ceramic jar. The bonding force between the bonding block 107 and the ceramic jar can be controlled by manually rotating the threaded rod 304, so as to better protect the ceramic jar.

[0038] Please see Figures 1-4 In this embodiment, one end of the rotating rod 206 extends out from the fixed frame 205. The end of the rotating rod 206 extending from the fixed frame 205 is provided with a rotating disk 400. The surface of the rotating rod 206 extending from the fixed frame 205 is fitted with a collar 401 connected to the fixed frame 205. Multiple clamping pieces 402 are evenly spaced along the circumferential direction at the end of the collar 401. A compression ring 403 is threaded onto the collar 401.

[0039] In this embodiment, the rotating disk 400 is fixedly connected to the rotating rod 206. By rotating the rotating disk 400, the rotating rod 206 can be driven to rotate, thereby adjusting the height of the support bar 103.

[0040] In this embodiment, the collar 401 is fixedly connected to the fixing frame 205. After the height of the support bar 103 is adjusted, the compression ring 403 can be rotated to move toward the clamping plate 402. As the compression ring 403 continues to move, it can drive the clamping plate 402 to deform and clamp the rotating rod 206, preventing the rotating rod 206 from rotating again after the height of the support bar 103 is adjusted.

[0041] The compression ring 403 has a certain length. When the clamping plate 402 grips the rotating rod 206, a portion of the compression ring 403 remains connected to the collar 401 to maintain the gripping state. When it is necessary to rotate the rotating rod 206, the compression ring 403 is rotated in the opposite direction to release the compression of the clamping plate 402, allowing the clamping plate 402 to return to its original shape.

[0042] In use, when fixing the ceramic jar, first place the ceramic jar on the fixing plate 109. Depending on the part of the ceramic jar that needs repair, rotate the rotating plate 400 to adjust the fitting block 107 to a suitable height, ensuring that the fitting block 107 does not obstruct the repair area. Next, rotate the threaded rod 304 to move one rod 104 towards the surface of the ceramic jar. When the fitting block 107 is close to the surface of the ceramic jar, the universal ball 105 can be rotated to adjust the fitting block 107 to a position where it can... The angle at which the adhesive block 107 fits against the surface of the ceramic jar is determined. Then, while holding the adhesive block 107, the threaded rod 304 is rotated to move the rod 104 toward the surface of the ceramic jar until the adhesive block 107 is completely in contact with the surface of the ceramic jar. Next, the opposite adhesive block 107 is manipulated to fit against the surface of the ceramic jar to initially fix the ceramic jar. Finally, the other two threaded rods 304 are rotated to make the adhesive blocks 107 fit against the surface of the ceramic jar completely, thus completing the fixation of the ceramic jar. After fixation, the ceramic jar can be repaired.

[0043] In summary, the above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall fall within the scope of the patent of the present utility model.
