DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] As Figures 1-5 shown, a quick fastening structure for a connecting rod includes a support rod 1; a fixing component 3 is connected to the support rod 1; moving grooves 7 are formed on both sides of the support rod 1; a clamping member 8 is installed in the moving groove 7; the fixing component 3 includes a sliding sleeve 31; a connecting column 32 is installed at the bottom of the sliding sleeve 31, and the connecting column 32 is slidably connected to the support rod 1; three connecting rods one 33 are fixedly connected to the bottom of the connecting column 32; a connecting rod two 34 is hinged to the bottom of the connecting rod one 33; the other end of the connecting rod two 34 is hinged to a clamping rod 35; a clamping plate 37 is fixedly connected to the bottom of the clamping rod 35; a plurality of fixing holes 39 are formed on both sides of the sliding sleeve 31, and the clamping member 8 is clamped in one of the fixing holes 39; three fixing frames 9 are installed on the fixing column 4; the top end of the clamping rod 35 is hinged to the fixing frame 9;

[0025] During operation, by pressing the clamping member 8, the clamping member 8 expands and contracts in the moving groove 7, so that the clamping member 8 disengages from the fixing hole 39 on the sliding sleeve 31, and then the sliding sleeve 31 is pulled, so that the sliding sleeve 31 drives the connecting rod one 33 to move upward, the connecting rod one 33 drives the connecting rod two 34 hinged thereto to move, and further the connecting rod two 34 drives the clamping rod 35 hinged thereto to move inward. The clamping rod 35 rotates offset through the fixing frame 9 hinged thereto, so that the three clamping rods 35 contract or expand in an umbrella shape. The three clamping rods 35 drive the clamping plate 37 connected thereto to clamp the bearing. After clamping the bearing, the clamping member 8 is clamped in the fixing hole 39 on the sliding sleeve 31, thereby fixing the bearing, and then the bearing is installed at a predetermined position; when the clamping rods 35 expand in an umbrella shape, the bearing can be clamped evenly and stably, ensuring the stability and safety of the bearing during the installation process. The close contact between the clamping plate 37 and the bearing reduces the shaking and offset of the bearing during the installation process, improving the installation accuracy;

[0026] By setting the fixed component 3, by pressing the clamping part 8 and moving the sliding sleeve 31, the positions of the clamping rod 35 and the clamping plate 37 can be quickly adjusted, realizing the quick clamping and release of the bearing. This design significantly improves the work efficiency and reduces the time and manpower required for installing and disassembling the bearing. The entire fastening structure is composed of components such as the support rod 1, the fixed component 3, the clamping part 8, the first connecting rod 33, the second connecting rod 34, the clamping rod 35, and the clamping plate 37. The structure is relatively simple, easy to manufacture and maintain. At the same time, the operation process is intuitive and clear, and it can be used without complex training.

[0027] Furthermore, as Figure 3 , 4 shown, the clamping part 8 includes a spring rod 81, and the left end of the spring rod 81 is fixed in the moving groove 7; the right end of the spring rod 81 is fixedly connected with a clamping rod 82, and the clamping rod 82 is clamped in one of the fixing holes 39 of the sliding sleeve 31; during work, press the clamping rod 82, so that the clamping rod 82 expands and contracts in the moving groove 7 through the spring rod 81, and then the clamping rod 82 is disengaged from the fixing hole 39 on the sliding sleeve 31, which is convenient for the fixed component 3 to clamp and fix the bearing according to the bearing size. After the bearing is fixed, the spring rod 81 utilizes its elastic characteristic to drive the clamping rod 82 to be clamped into the fixing hole 39 on the sliding sleeve 31 again, thereby fixing the bearing. Since there are multiple fixing holes 39 on the sliding sleeve 31, the positions of the clamping rod 35 and the clamping plate 37 can be adjusted as needed to adapt to bearings of different sizes and shapes, which improves the versatility and flexibility of this fastening structure and enables it to be used in a variety of scenarios.

[0028] Furthermore, as Figure 1 , 5 shown, the bottom of the support rod 1 is fixedly connected with a first screw rod 2; the first screw rod 2 is threadedly connected with a fixed column 4; a threaded groove 5 is provided on the fixed column 4; the fixed column 4 is threadedly connected to the first screw rod 2 through the threaded groove 5; the three first connecting rods 33 are slidably connected to the fixed column 4;

[0029] During work, by first pressing the clamping part 8 to disengage the clamping part 8 from the fixing hole 39 on the sliding sleeve 31, then rotating the fixed column 4, so that the fixed column 4 drives the adjusting component to rotate on the first screw rod 2 threadedly connected thereto, and then the fixed column 4 drives the adjusting component to disengage from the first screw rod 2, and then rotating the support rod 1, so that the main support rod disengages from the connection of the threaded rod 10 through the threaded groove 5, and then rotating the fixed handle 13, so that the fixed handle 13 disengages from the threaded connection of the connecting rod 11 through the first bolt 12, making the overall structure detachable and convenient for maintenance and storage;

[0030] The connections between the various components of this structure are all detachable methods such as threaded connections or sliding connections. Therefore, during maintenance, the components that need to be repaired or replaced can be easily removed, facilitating subsequent maintenance work. By pressing the clamping part 8 to disengage it from the fixing hole 39 on the sliding sleeve 31, then rotating the fixing column 4 to loosen its threaded connection with the first screw 2, and then rotating the support rod 1 to separate it from the fixing column 4, this series of operations is simple and fast, and the entire fastening structure can be quickly disassembled into multiple parts, greatly improving the disassembly efficiency. The volume of each component after disassembly is relatively small, and they can be conveniently stacked or stored in a toolbox, greatly saving storage space;

[0031] At the same time, when in need of use, the various components can also be quickly assembled to restore their original functions. This design enables the fastening structure to be flexibly assembled and disassembled as needed, suitable for different working environments and requirements. For example, in occasions where bearings need to be frequently replaced or the equipment position needs to be adjusted, this fastening structure can greatly improve work efficiency and flexibility.

[0032] Furthermore, as shown in Figure 1 、 2 , a number of heat-conducting sheets 6 are installed on the clamping plate 37, and an anti-slip pad 38 is installed on the inner side of the clamping plate 37. When clamping an object with a relatively high temperature, the heat of the object is conducted to the heat-conducting sheets 6 through the clamping plate 37, and the heat-conducting sheets 6 accelerate the heat dissipation of the object. The anti-slip pad 38 usually has a rough surface or special texture, which can significantly increase the friction between the clamping plate 37 and the bearing or other clamped objects. During the clamping process, the anti-slip pad 38 can effectively reduce the sliding or falling off of the clamped object due to external forces, ensuring the stability of the clamping.

[0033] Furthermore, as shown in Figure 2 、 3 、5, a connection groove 14 is provided on the support rod 1; a threaded rod 10 is threadedly connected in the connection groove 14. During operation, rotate the support rod 1 so that the support rod 1 rotates on the threaded rod 10 threadedly connected thereto through the connection groove 14, thereby separating the connecting rod 11 from the support rod 1.

[0034] Furthermore, as shown in Figure 1 、 5 , a connecting rod 11 is installed on the threaded rod 10; a fixing handle 13 is threadedly connected to the connecting rod 11, and a first bolt 12 is installed on the fixing handle 13; the fixing handle 13 is threadedly connected to the top of the connecting rod 11 through the first bolt 12. During operation, rotate the fixing handle 13 so that the fixing handle 13 drives the first bolt 12, and then disengages from the top of the connecting rod 11 connected thereto, enabling the fixing handle 13 to be installed at any time when in use and removed at any time when not in use.

[0035] Working principle: During operation, by pressing the clamping member 8, the clamping member 8 expands and contracts within the moving groove 7, causing the clamping member 8 to disengage from the fixing hole 39 on the sliding sleeve 31. Then, by pulling the sliding sleeve 31, the sliding sleeve 31 drives the first connecting rod 33 to move upward. The first connecting rod 33 drives the second connecting rod 34 hinged thereto to move, and further the second connecting rod 34 drives the clamping rod 35 hinged thereto to move inward. The clamping rod 35 offsets and rotates through the fixing bracket 9 hinged thereto, causing the three clamping rods 35 to contract or expand in an umbrella shape. The three clamping rods 35 drive the clamping plate 37 connected thereto to clamp the bearing. After clamping the bearing, the clamping member 8 is clamped within the fixing hole 39 on the sliding sleeve 31, thereby fixing the bearing. Then, the bearing is installed at a predetermined position; During operation, by pressing the clamping rod 82, the clamping rod 82 expands and contracts within the moving groove 7 through the spring rod 81, thereby causing the clamping rod 82 to disengage from the fixing hole 39 on the sliding sleeve 31, facilitating the fixing assembly 3 to clamp and fix the bearing according to the bearing size. After the bearing is fixed, the spring rod 81 utilizes its elastic characteristic to drive the clamping rod 82 to snap into the fixing hole 39 on the sliding sleeve 31 again, thereby fixing the bearing; During operation, by first pressing the clamping member 8, the clamping member 8 is disengaged from the fixing hole 39 on the sliding sleeve 31. Then, by rotating the fixing column 4, the fixing column 4 drives the adjusting assembly to rotate on the first screw rod 2 threadedly connected thereto, thereby causing the fixing column 4 to drive the adjusting assembly to disengage from the first screw rod 2. Then, by rotating the support rod 1, the main support rod disengages from the connection with the threaded rod 10 through the threaded groove 5. Then, by rotating the fixing handle 13, the fixing handle 13 disengages from the threaded connection with the connecting rod 11 through the first bolt 12, enabling the overall structure to be disassembled; During operation, by rotating the support rod 1, the support rod 1 rotates on the threaded rod 10 threadedly connected thereto through the connection groove 14, thereby causing the connecting rod 11 and the support rod 1 to disengage; During operation, by rotating the fixing handle 13, the fixing handle 13 drives the first bolt 12 to disengage from the top of the connecting rod 11 connected thereto, enabling the fixing handle 13 to be installed at any time when in use and disassembled at any time when not in use.
