[0020] 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.

[0021] Please see Figure 1-5 This utility model provides an embodiment of a hydraulic filter element connecting device, including a central tube 1 and a connecting plate 2 installed on the top of the central tube 1. A fixed plate 31 is connected to the top of the connecting plate 2, and a turntable 32 is rotatably connected to the top of the fixed plate 31. The top of the turntable 32 has four arc grooves 33, and sliding rods 34 are movably connected inside the four arc grooves 33. A sliding plate 35 is connected to the top of the sliding rods 34, and clamping plates 36 are installed on the sliding plate 35. Four clamping plates 36 are provided. A support frame 37 is connected to the top of the fixed plate 31, and the sliding plate 35 is slidably connected to the support frame 37. A movable groove 38 is opened at the outer end of the support frame 37, and a moving groove 39 is opened on the lower side of the outer end of the support frame 37. Four threaded rods 310 are rotatably connected to the outer end of the turntable 32. The outer end is threaded with a swivel ring 311. By setting a linkage structure between the turntable 32 and the arc groove 33, and with the sliding guide design of the sliding rod 34, the slide plate 35 and the support frame 37, the filter element can be quickly connected and disassembled. When the turntable 32 is rotated, the sliding rod 34 moves along the arc groove 33, driving the slide plate 35 to slide along the movable groove 38 and the moving groove 39 of the support frame 37, so that the four clamping plates 36 open and close synchronously, quickly completing the clamping or loosening of the filter element. At the same time, the threaded rod 310 and the swivel ring 311 form a reliable locking mechanism, which can prevent the connection from loosening after tightening. This design makes the filter element replacement operation convenient and efficient, greatly reducing equipment downtime and maintenance costs. The locking mechanism ensures a stable connection, effectively avoiding leakage and loosening failures, and improving the stability and reliability of the hydraulic system.

[0022] Please see Figure 2-5 A further solution based on this embodiment is as follows: the filter element is placed inside the central tube 1, and the threaded rod 310 is pushed to rotate around the fixed plate 31. The threaded rod 310 drives the turntable 32 to rotate, and the turntable 32 drives the slide plate 35 to slide on the support frame 37 through the arc groove 33, so that the clamping plate 36 clamps the filter element. The filter element is quickly clamped through mechanical linkage. The operation is smooth and labor-saving, ensuring that the filter element is firmly fixed inside the central tube 1 and avoiding displacement due to vibration during use.

[0023] Please see Figure 1-5A further solution based on this embodiment is as follows: multiple oil outlet holes 41 are provided at the outer end of the central tube 1, and a disc 42 is connected to the lower inner side of the central tube 1. The oil outlet holes 41 provide an outlet channel for the filtered oil to ensure unobstructed oil flow. The disc 42 provides support for the bottom of the filter element to prevent the filter element from sinking and maintain the stability of the filtration position.

[0024] Please see Figure 1-5 A further solution based on this embodiment is as follows: a conical head 43 is connected to the top of the disc 42, and a threaded groove 44 is opened on the top of the support frame 37. The conical head 43 is inserted into the bottom of the filter element to achieve precise positioning of the filter element and avoid installation offset from affecting the filtration effect. The threaded groove 44 provides a matching interface for the connection of the cover plate 46, laying the foundation for the sealing structure.

[0025] Please see Figure 1-5 A further solution based on this embodiment is as follows: a threaded post 45 is connected to the inside of the threaded groove 44, and a cover plate 46 is connected to the top of the threaded post 45. The cooperation between the threaded post 45 and the threaded groove 44 makes the cover plate 46 tightly cover the top of the support frame 37, forming a closed space, which effectively prevents oil leakage. The cover plate 46 also protects the top of the filter element and reduces external pollution.

[0026] Please see Figure 1-5 A further solution based on this embodiment is as follows: a slot 47 is provided on the top of the cover plate 46, and an oil inlet pipe 48 is connected to the front end of the connecting plate 2. The oil inlet pipe 48 is connected to the central pipe 1. The slot 47 facilitates the insertion of external tools to rotate the cover plate 46, thereby achieving quick disassembly and assembly. The oil inlet pipe 48 introduces the oil to be filtered into the central pipe 1, providing a stable oil source for the filter element filtration and ensuring the continuity of the filtration process.

[0027] Please see Figure 1-5 A further solution based on this embodiment is as follows: the conical head 43 is used to position the filter element, the threaded post 45 on the cover plate 46 is threadedly connected to the threaded groove 44, and the cover plate 46 is removed by rotating it by inserting an external tool into the slot 47. The conical head 43 ensures that the filter element is installed in a precise position and improves the filtration efficiency. The threaded connection of the cover plate 46 and the design of the slot 47 are combined to ensure the reliability of the seal and simplify the disassembly and assembly steps of the cover plate 46, making it convenient to quickly replace the filter element.

[0028] Working principle: The filter element to be installed is first placed inside the central tube 1, with the bottom supported by a disc 42 to prevent it from sinking. The conical head 43 at the top of the disc 42 is inserted into the bottom of the filter element for precise positioning, avoiding installation misalignment that could affect the filtration effect. Subsequently, the threaded rod 310 is pushed to rotate around the fixed disc 31, causing the turntable 32 to rotate synchronously. The arc groove 33 on the turntable 32 drives the sliding plate 35 to slide along the movable groove 38 and moving groove 39 of the support frame 37 via the sliding rod 34, causing the four clamping plates 36 to tighten synchronously, firmly clamping the filter element inside the central tube 1 to prevent displacement due to vibration during use. At the same time, the rotating ring 311 at the outer end of the threaded rod 310 is rotated to form a locking mechanism, further ensuring that the connection is secure. During oil filtration, the oil to be filtered... Oil enters the central tube 1 through the inlet pipe 48 at the front end of the connecting plate 2, flows through the filter element to complete filtration, and then flows out through the outlet hole 41 at the outer end of the central tube 1 to enter the subsequent oil circuit. The cover plate 46 on the top of the support frame 37 is threadedly connected to the threaded groove 44 through the threaded post 45, tightly covering and forming a closed space, effectively preventing oil leakage, and protecting the top of the filter element from external contamination. If the filter element needs to be replaced, the cover plate 46 can be quickly removed by inserting an external tool into the slot 47 on the top of the cover plate 46 and rotating it. The operation is convenient. The whole system achieves precise installation, stable fixation and efficient filtration of the filter element through the coordinated cooperation of positioning, clamping, locking and sealing. At the same time, it simplifies the disassembly and assembly process, reduces equipment downtime for maintenance, and improves the operational stability of the hydraulic system.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
