Reinforcing the wooden railings of ancient buildings can protect and extend their service life while ensuring the safety and stability of the building structure.

[0003] The current method of reinforcing wooden railings is rather cumbersome. Generally, iron rings and other workpieces are clamped on the surface of the railings through multiple sets of bolt fasteners. Although this reinforcement method is relatively strong, it also has obvious defects, namely, it is difficult to maintain, it is not easy to quickly remove the reinforcements, and it is difficult to quickly and effectively protect the reinforced parts (such as painting). Utility Model Content

[0004] In view of this, the purpose of the present invention is to solve the shortcomings of the background technology and to propose a reinforcement device for wooden railings to solve the problems existing in the prior art.

[0005] To achieve the above objectives, the utility model provides a reinforcement device for wooden railings, comprising a fixing frame, the top of the fixing frame is fixedly connected to a fixing tube, the inner side of the fixing frame is fixedly penetrated by a frame shaft, the outer surface of the frame shaft is rotatably connected to a hoop ring through a manual adjustment mechanism, the inner side of the hoop ring is provided with a rubber pad, the bottom of the hoop ring is fixedly connected to a fixing seat, the inner side of the fixing seat is slidably connected to an L-shaped rod through a shifting mechanism, and the top of the L-shaped rod is provided with a protective arc plate.

[0006] Preferably, the manual adjustment mechanism includes a screw threadedly sleeved on the inner surface of the fixed cylinder, and a handle is provided on the top of the screw. The hoop frame can be adjusted by the manual adjustment mechanism, so that the two sets of hoop frames can stably clamp and protect the cracks of the railing during the gradual retraction process.

[0007] Preferably, the bottom of the screw rod is rotatably connected to a shift frame, and an upper plate shaft is fixedly penetrated through the inner side of the shift frame.

[0009] Preferably, the shifting mechanism includes a rotating rod rotatably connected to the inner surface of the fixing seat, and a knob is provided at the end of the rotating rod away from the fixing seat. The two sets of protective arc plates can be displaced by the shifting mechanism to different positions on the outer surface of the railing, thereby effectively shielding and protecting the damaged parts.

[0010] Preferably, a gear is fixedly sleeved on the outer surface of the rotating rod, and a rack is fixedly connected to one end of the L-shaped rod away from the protective arc plate, and the outer surface of the rack is meshed with the outer surface of the gear.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This reinforcement device for wooden railings can use two sets of hoop rings in conjunction with rubber pads through a manual adjustment mechanism to stably clamp and protect cracked or deformed parts of wooden railings. The hoop rings can be quickly reinforced or removed by simply twisting the handle, which facilitates maintenance and reduces damage to the surface of wooden railings of ancient buildings.

[0013] 2. The reinforcement device for wooden railings can adjust the position of the protective arc plate through a shifting mechanism, so that it forms a barrier around the damaged part of the wooden railing, effectively blocking the further impact of the external environment on the damaged part. This function not only enhances the protective effect of the wooden railing, but also extends its service life. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0019] See also Figure 1-3 A reinforcement device for wooden railings includes a fixing frame 1, the top of the fixing frame 1 is fixedly connected to a fixing tube 2, the inner side of the fixing frame 1 is fixedly penetrated with a frame shaft 3, the outer surface of the frame shaft 3 is rotatably connected to a hoop ring 4 through a manual adjustment mechanism, the inner side of the hoop ring 4 is provided with a rubber pad 5, the bottom of the hoop ring 4 is fixedly connected to a fixing seat 12, the inner side of the fixing seat 12 is slidably connected to an L-shaped rod 13 through a shift mechanism, and the top of the L-shaped rod 13 is provided with a protective arc plate 14.

[0020] Through the above technical solution, the reinforcement device can adjust the two sets of hoop rings 4 through a manual adjustment mechanism during use, so that they can cooperate with the rubber pads 5 to stably clamp the cracked or deformed parts of the wooden railings, and the position of the protective arc plate 14 can be adjusted under the action of the shifting mechanism to adjust it to the damaged parts at different positions on the railing surface to provide shielding and protection.

[0021] Specifically, the manual adjustment mechanism includes a screw rod 6 threadedly sleeved on the inner surface of the fixed cylinder 2 , and a handle 7 is provided on the top of the screw rod 6 .

[0022] Through the above technical solution, rotating the handle 7 can drive the screw 6 to rotate, during which the screw 6 will gradually move longitudinally along the inner surface of the fixed tube 2.

[0023] Specifically, the bottom of the screw rod 6 is rotatably connected to the shift frame 8 , and the inner side of the shift frame 8 is fixedly penetrated by an upper plate shaft 9 .

[0024] Through the above technical solution, the shift frame 8 will be displaced synchronously with the longitudinal movement of the screw rod 6, thereby pushing and pulling the driving plate 10 through the upper plate shaft 9.

[0025] Specifically, the outer surface of the upper plate shaft 9 is rotatably connected to the driving plate 10 , the inner side of the hoop ring 4 is fixedly penetrated with a lower plate shaft 11 , and the outer surface of the lower plate shaft 11 is rotatably connected to the bottom of the driving plate 10 .

[0026] Through the above technical solution, after the driving plate 10 is pushed or pulled, its bottom end will rotate along the lower plate shaft 11 and push or pull the hoop ring 4 through the lower plate shaft 11.

[0027] Specifically, the shifting mechanism includes a rotating rod 15 rotatably connected to the inner surface of the fixing seat 12 , and a knob 16 is provided at one end of the rotating rod 15 away from the fixing seat 12 .

[0028] Through the above technical solution, the rotating rod 15 will be linked to the gear 17 to rotate during the rotation process, and the rack 18 meshing with the gear 17 will be driven to move laterally.

[0029] Specifically, a gear 17 is fixedly sleeved on the outer surface of the rotating rod 15 , and a rack 18 is fixedly connected to one end of the L-shaped rod 13 away from the protective arc plate 14 , and the outer surface of the rack 18 is meshed with the outer surface of the gear 17 .

[0030] Through the above technical solution, during the lateral movement of the rack 18, the protective arc plate 14 is driven to move to the corresponding position through the L-shaped rod 13, forming a protective barrier around the damaged part of the railing.

[0031] Working principle: When reinforcing the wooden railings of ancient buildings, the reinforcement device can first find the cracks or deformations of the railings, then place the railing parts at the cracks or deformations on the inner sides of the two sets of hoop frame rings 4, and then twist the handle 7 to drive the screw 6 to rotate. The screw 6 will gradually move up along the inside of the fixed tube 2 during the rotation, and the shift frame 8 connected to the bottom rotation of the screw 6 will move up synchronously. During this period, the shift frame 8 will pull the driving plate 10 through the upper plate shaft 9, so that the driving plate 10 deflects, and the driving plate 10 will rotate along the lower plate shaft 11 during the deflection process, and pull the hoop frame ring 4 through the lower plate shaft 11, so that in the process of the hoop frame ring 4 rotating along the frame shaft 3, the bottom of the hoop frame ring 4 will gradually approach until the two The group of hoop rings 4 are completely closed, and the rubber pads 5 are used to stably clamp the wooden railings at the cracked or deformed parts, thereby strengthening the wooden railings. When removing the hoop rings 4, it is only necessary to rotate the handle 7 in the opposite direction so that the bottom ends of the two groups of hoop rings 4 are separated from each other and no longer stably clamp the railings. At the same time, the knob 16 can be turned to drive the rotary rod 15 to rotate. In the process of the rotary rod 15 driving the gear 17 to rotate, the rack 18 will be driven to move laterally. Finally, the position of the protective arc plate 14 is adjusted laterally through the L-shaped rod 13 to move it to the periphery of the damaged part of the wooden railing, forming a protective barrier on its periphery, reducing the impact of the external environment on the damaged part of the wooden railing, and improving the protective effect.
