Description

Technical Field

[0001] This utility model belongs to the field of textile machine connecting rod technology, specifically relating to a quick-release connector device for textile machine connecting rods. Background Technology

[0002] As a core component of textile machinery, the connecting rod of a textile machine bears the important responsibility of transmitting power and motion, as well as connecting various parts. Its design and performance directly affect the operating accuracy, stability, and production efficiency of the textile machine. In practical applications, quick-connect couplings are typically used to facilitate the rapid connection and disassembly of the connecting rod.

[0003] However, existing quick-connect coupling devices have a pressing problem: at the connection point between the device and the textile machine connecting rod, lubricating oil is needed to ensure smooth operation and reduce wear. However, during use, lubricating oil seeps out from the connection and gradually flows onto the surface of the quick-connect coupling device. This not only results in direct waste of lubricating oil and increases production costs, but also, considering the recycling value of lubricating oil, this meaningless loss seems even more counterproductive. In the long run, the waste of lubricating oil not only affects the economic benefits of enterprises but may also cause potential environmental pollution. Utility Model Content

[0004] The purpose of this invention is to provide a quick-release coupling device for textile machine connecting rods, aiming to solve the problem in existing technologies where lubricating oil is needed at the connection between the device and the textile machine connecting rod to ensure smooth operation and reduce wear. However, during use, lubricating oil seeps out from the connection and gradually flows to the surface of the quick-release coupling device. This not only directly wastes lubricating oil and increases production costs, but also, considering the recycling value of lubricating oil, this meaningless loss is even more counterproductive. In the long run, the waste of lubricating oil not only affects the economic benefits of enterprises but may also cause potential environmental pollution.

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

[0022] 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.

[0023] Please see Figures 1-5 This utility model provides the following technical solution: a quick-release connector device for a textile machine connecting rod, including a first connector rod 1 and a second connector rod 3. The front and rear ends of the second connector rod 3 are connected to an annular block 4. A fixing bolt 5 is threaded through the surface of the annular block 4. A groove 6 is provided at the back end of the annular block 4. An annular sealing gasket 7 is adhered to the back end of the annular block 4. An oil drain hole 8 is provided through the surface of the groove 6. An oil tank 9 is installed on the surface of the annular block 4 by screws. A first threaded rod 2 is connected to the top end of the annular block 4. A first threaded groove 10 is provided at the top end of the first threaded rod 2. A second threaded groove 12 that matches the first threaded rod 2 is provided at the bottom end of the second connector rod 3. A second threaded rod 11 is installed inside the second threaded groove 12. A compression bolt 13 is connected to the side wall of the second connector rod 3.

[0024] During specific use, the quick-release joint device is composed of a first joint rod 1 and a second joint rod 3. These two parts are usually made of metal materials such as steel and cast iron. This can not only ensure that the device has sufficient strength and stiffness to work stably, but also take into account reducing the overall weight of the device. In practical applications, the quick-release joint device will be connected to the connecting rod of the textile machine to meet the operation requirements of the textile machine.

[0025] It is particularly worth noting that: the end of the first joint rod 1 is provided with an external thread, and the corresponding end of the connected connecting rod is provided with an internal thread. The two are tightly fitted through the external thread and the internal thread to achieve a firm connection between the first joint rod 1 and the connecting rod; between the second joint rod 3 and the connecting rod, a pin connection method is adopted. This enables the connecting rod of the textile machine and the joint device to achieve quick loading and unloading, greatly improving the equipment assembly and maintenance efficiency.

[0026] Preferably: the annular block 4 can be detachably and fixedly connected to the second joint rod 3 through the fixing bolts 5. Four fixing bolts 5 are threadedly connected and evenly distributed on the surface of the annular block 4. The inner circle of the cross-section of the annular block 4 and the groove 6 are in a "convex" shape.

[0027] During specific use, when the quick-release joint device is connected to the connecting rod of the textile machine, lubricating oil will be added at their connection to ensure the smooth operation of the equipment. However, during the combined operation of the quick-release joint device and the connecting rod of the textile machine, the lubricating oil may leak along the connection. At this time, the leaked lubricating oil will flow into the pre-set groove 6 along the way, and flow into the oil storage tank 9 through the oil drain holes 8 specifically opened in the groove 6 for unified centralized storage.

[0028] This design realizes the effective recovery of the leaked lubricating oil, not only avoiding the direct waste of the lubricating oil, reducing the additional cost brought by the loss of the lubricating oil, but also having significant environmental and economic value.

[0029] It is worth noting that: the annular gasket 7 can seal the gap between the annular block 4 and the second joint rod 3 to prevent the leakage of lubricating oil.

[0030] Preferably: the first joint rod 1 can be threadedly connected to the second joint rod 3 through the first threaded rod 2 and the second threaded groove 12. The first joint rod 1 can be threadedly connected to the second joint rod 3 through the second threaded rod 11 and the second threaded groove 12. The first joint rod 1 can be squeeze-connected to the second joint rod 3 through the squeeze bolt 13.

[0031] In practical use, when the quick-release connector is connected to the connecting rod of the textile machine and there is a need to adjust the length, the operator only needs to rotate the first connector rod 1 to start its movement. As the first connector rod 1 rotates, it drives the first threaded rod 2 to engage with the corresponding first threaded groove 10 on the second connector rod 3. Simultaneously, the second threaded rod 11 also engages tightly with the second threaded groove 12, forming a stable threaded connection. Under the action of the threaded engagement, the first threaded rod 2 gradually moves out of the second connector rod 3, thereby achieving flexible adjustment of the connection length between the first connector rod 1 and the second connector rod 3.

[0032] This innovative design completely breaks free from the constraints of fixed-length traditional connector rods, enabling the quick-connect and disconnect device to easily adapt to various length requirements in textile machine connecting rod scenarios. This not only greatly enhances the versatility and practicality of the connector device but also effectively reduces replacement and time costs caused by length mismatches, bringing significant benefits to the textile industry in terms of production efficiency and cost control.

[0033] Working Principle: First, when the quick-release coupling device is connected to the textile machine connecting rod and there is a need to adjust the length, the operator simply rotates the first coupling rod 1 to initiate its movement. As the first coupling rod 1 rotates, it drives the first threaded rod 2 to engage with the corresponding first threaded groove 10 on the second coupling rod 3. During this process, the clamping bolt 13 needs to be rotated to release the clamping fixation between the first threaded rod 2 and the second coupling rod 3. Simultaneously, the second threaded rod 11 will also tightly engage with the second threaded groove 12, forming a stable threaded connection. Under the action of the threaded engagement, the first threaded rod 2 gradually moves out from the inside of the second coupling rod 3, thereby achieving flexible adjustment of the connection length between the first coupling rod 1 and the second coupling rod 3. After the quick-release coupling device is connected to the textile machine connecting rod, lubricating oil is added to their connection point to ensure smooth operation of the equipment. However, during the operation of the quick-release coupling device and the textile machine connecting rod, lubricating oil may leak along the connection point. At this time, the leaked lubricating oil will flow into the pre-set groove 6 and then into the oil storage tank 9 for unified and centralized storage through the oil drain hole 8 specifically opened in the groove 6.

[0034] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
