Description

Technical Field

[0001] This utility model relates to the field of electric linear actuator technology, specifically to an electric linear actuator that can be quickly assembled and disassembled. Background Technology

[0002] An electric linear actuator is a device that converts the rotary motion of an electric motor into the linear reciprocating motion of a linear actuator. It mainly consists of a motor, a reducer, a linear actuator, and a control device. Electric linear actuators are characterized by their compact structure, large thrust, low noise, and smooth operation. They are widely used in various mechanical equipment that require linear motion, such as automated production lines, medical equipment, stage equipment, and automobile manufacturing. By precisely controlling the rotation of the motor, the stroke, speed, and thrust of the linear actuator can be precisely adjusted to meet the needs of different application scenarios.

[0003] According to patent document CN221509310U, an electric push rod is disclosed, comprising: one end of a lead screw disposed in a control cavity, a sleeve rod fixedly connected to the control cavity, and the other end of the lead screw extending into the sleeve rod; a telescopic rod slidably connected to the sleeve rod, and the telescopic rod being fixedly connected to the lead screw; when the telescopic rod needs to move linearly, the lead screw rotates to drive the telescopic rod to move; the rotating component includes a support rod, a rotating plate, a rotating shaft, and a locking plate; the support rod is fixedly connected to the other end of the fixed plate; the rotating plate is fixedly connected to the support rod; the rotating shaft is fixedly connected to the inner wall of the sleeve rod, and the rotating shaft is rotatably connected to the rotating plate; the locking plate is fixedly connected to the rotating plate; the movement of the fixed plate drives the support rod to move, causing the rotating plate to rotate, thereby causing the locking plate to rotate and fix the locking plate to the sleeve rod; when the telescopic rod extends to a fixed position, the position of the telescopic rod can be restricted, thereby preventing the telescopic rod from exceeding the limit position and causing damage to the electric push rod.

[0004] In traditional electric linear actuator designs, the extension rod is usually tightly connected to the main body. After prolonged operation or frequent use, the extension rod may need to be replaced due to wear, aging, or other forms of damage. However, because the connection between the extension rod and the main body of a traditional electric linear actuator is relatively fixed, the process of replacing a damaged extension rod becomes quite cumbersome and time-consuming. Users may need to spend a lot of time and effort to disassemble and reinstall a new extension rod, which not only affects work efficiency but may also cause unnecessary damage to other components of the electric linear actuator due to improper operation during the replacement process. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a quick-release electric push rod, thereby enabling rapid replacement of the extension rod and improving maintenance efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution: it includes an electric push rod body, and an extension rod connector is movably connected to the inner wall of the top left side of the electric push rod body, and an extension rod is provided at the top of the extension rod connector;

[0007] The extension rod includes an extension rod housing, and a lead screw is fixedly connected to the top of the inner wall of the extension rod housing;

[0008] The extension rod connector includes a chassis, a hydraulic push rod is fixedly connected to the top of the chassis, and side guide rods are fixedly connected to the left and right sides of the top of the chassis, respectively.

[0009] Preferably, a top connecting tube is fixedly connected to the top of the outer side of the two side guide rods, and a connecting groove is provided in the middle of the top of the top connecting tube.

[0010] Preferably, the inner wall of the extension rod housing is movably connected to the outer wall of the top connecting tube, the outer wall of the lead screw is threadedly connected to the inner wall of the connecting groove, and both sides of the outer wall of the top connecting tube are hollowed out.

[0011] Preferably, a T-shaped push block is fixedly connected to the top of the hydraulic push rod, and the outer wall of the T-shaped push block is slidably connected to the inner side of the two side guide rods.

[0012] Preferably, two rotating rods are rotatably connected to the left and right sides of the front and rear sides of the top center of the T-shaped push block, and a retractable rod connecting block is rotatably connected to the side of the multiple sets of rotating rods away from the T-shaped push block.

[0013] Preferably, the inner sides of the two expansion rod connecting blocks are fixedly connected with expansion rods, and the outer sides of the two expansion rods are respectively aligned with the hollowed-out areas on both sides of the top connecting tube.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. By incorporating an extension rod connector and an extension rod, the electric push rod achieves rapid assembly and disassembly, significantly enhancing its stability and safety during use. Particularly in reinforcing the connection between the extension rod connector and the extension rod, this invention employs a hydraulic push rod to drive the T-shaped push block to rise and fall. Through a linkage mechanism involving the rotating rod, the retractable / expanding rod connector, and the retractable / expanding rod, the retractable / expanding rod achieves a tight engagement of the retractable / expanding rod with the inner wall of the extension rod. This innovative design effectively enhances the stability of the extension rod, preventing potential safety hazards caused by loosening. Furthermore, the entire assembly and disassembly process is simple to operate, requiring no complex tools or steps, greatly improving work efficiency and reducing operating costs. In summary, during use, the hydraulic push rod drives the T-shaped push block to rise and fall. The rising T-shaped push block rotates the retractable / expanding rod connector, causing the retractable / expanding rod to expand and clamp onto the inner wall of the extension rod for a reinforced connection. During disassembly, the hydraulic push rod lowers the T-shaped push block, causing the retractable / expanding rod to retract, and the extension rod can be removed by rotating the outer casing.

[0016] 2. By setting up an extension rod connector and an extension rod, quick assembly and disassembly can be achieved by rotating the extension rod housing. This not only simplifies the operation process but also greatly improves work efficiency. Specifically, when assembling or disassembling the extension rod, rotating the housing causes the lead screw to rotate in the threaded groove of the connecting slot, which can be quickly removed. The operation is simple and improves efficiency. Attached Figure Description

[0023] 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.

[0024] Please see Figure 1-2 This utility model provides a technical solution: it includes an electric push rod body 1, an extension rod connector 2 is movably connected to the inner wall of the top left side of the electric push rod body 1, and an extension rod 3 is provided on the top of the extension rod connector 2.

[0025] Please see Figure 3-4 The extension rod 3 includes an extension rod housing 31, and a lead screw 32 is fixedly connected to the top of the inner wall of the extension rod housing 31. The extension rod connector 2 includes a chassis 21, and a hydraulic push rod 23 is fixedly connected to the top of the chassis 21. Side guide rails 22 are fixedly connected to the left and right sides of the top of the chassis 21 respectively. A top connecting tube 28 is fixedly connected to the top of the outer side of the two side guide rails 22. A connecting groove 29 is opened in the middle of the top of the top of the top connecting tube 28. The inner wall of the extension rod housing 31 is movably connected to the outer wall of the top connecting tube 28. The outer wall of the lead screw 32 is threadedly connected to the inner wall of the connecting groove 29. Both sides of the outer wall of the top connecting tube 28 are hollowed out.

[0026] During the assembly and disassembly of the extension rod 3, the user only needs to perform a simple rotation action, namely, rotating the extension rod housing 31. In this way, the lead screw 32 will rotate in the inner thread of the connecting groove 29, so that the extension rod 3 can be easily removed from the outer wall of the top connecting tube 28. This design not only makes the assembly and disassembly of the extension rod 3 quick and convenient, but also significantly improves work efficiency. In addition, the presence of the extension rod connector 2 ensures that the extension rod 3 can maintain a stable state during the assembly and disassembly process, effectively avoiding possible shaking or tilting. This design further improves the accuracy and safety of the assembly and disassembly process, providing great convenience for users and making the assembly and disassembly operation easier and more worry-free.

[0027] Please see Figure 4-5 The top of the hydraulic push rod 23 is fixedly connected to a T-shaped push block 24. The outer wall of the T-shaped push block 24 is slidably connected to the inner side of the two side guide rods 22. The top center of the T-shaped push block 24 is rotatably connected to two rotating rods 27 on the left and right sides of the front and rear sides. The side of the multiple rotating rods 27 away from the T-shaped push block 24 is rotatably connected to a shrinking rod connecting block 25. The inner side of the two shrinking rod connecting blocks 25 is fixedly connected to a shrinking rod 26. The outer sides of the two shrinking rods 26 are aligned with the hollowed-out parts on both sides of the top connecting tube 28.

[0028] In practical applications, to further enhance the connection stability between the extension rod connector 2 and the extension rod 3, a hydraulic push rod 23 is used to drive the T-shaped push block 24 to perform lifting and lowering operations. When the T-shaped push block 24 moves upward, it drives the retractable rod connector 25 to rotate via the rotating rod 27. Subsequently, the retractable rod connector 25 drives the retractable rod 26 to perform a corresponding expansion action. In this way, the outer part of the retractable rod 26 can extend to its outer wall through the hollow areas on both sides of the top connecting tube 28 and is firmly locked onto the inner wall of the extension rod 3. This mechanism significantly enhances the connection strength between the extension rod connector 2 and the extension rod 3. When it is necessary to disassemble the extension rod 3, simply operate the hydraulic push rod 23 to lower the T-shaped push block 24, and the retractable rod 26 will retract accordingly. At this time, by rotating the extension rod housing 31, the extension rod 3 can be easily disassembled. This design not only improves the stability of the extension rod 3 and ensures its firmness during use, but also further enhances the convenience and safety of the disassembly and assembly process.

[0029] Working principle: During the disassembly and assembly of extension rod 3, the user only needs to perform a simple rotation action, namely, rotating the extension rod housing 31. In this way, the lead screw 32 will rotate in the inner wall thread of the connecting groove 29, so that the extension rod 3 can be easily removed from the outer wall of the top connecting tube 28. This design not only makes the disassembly and assembly of extension rod 3 quick and convenient, but also significantly improves work efficiency. In addition, the presence of extension rod connector 2 ensures that extension rod 3 can maintain a stable state during disassembly and assembly, effectively avoiding possible shaking or tilting during disassembly and assembly. This design further improves the accuracy and safety of the disassembly and assembly process.

[0030] In practical applications, to further enhance the connection stability between the extension rod connector 2 and the extension rod 3, a hydraulic push rod 23 is used to drive the T-shaped push block 24 to perform lifting and lowering operations. When the T-shaped push block 24 moves upward, it drives the retractable rod connector 25 to rotate via the rotating rod 27. Subsequently, the retractable rod connector 25 drives the retractable rod 26 to perform corresponding expansion actions. In this way, the outer part of the retractable rod 26 can extend to its outer wall through the hollow areas on both sides of the top connecting tube 28 and is firmly locked onto the inner wall of the extension rod 3. This mechanism significantly enhances the connection strength between the extension rod connector 2 and the extension rod 3. When it is necessary to disassemble the extension rod 3, simply operate the hydraulic push rod 23 to lower the T-shaped push block 24, and the retractable rod 26 will retract accordingly. At this time, the extension rod 3 can be easily disassembled by rotating the extension rod housing 31.
