Description

Technical Field

[0001] This utility model relates to the field of sealing equipment technology, specifically to an automatic sealing plug device. Background Technology

[0002] In industrial production, many equipment and processes require sealing of openings in pipes, containers, or workpieces. For example, in the transportation of corrosive liquids in chemical pipelines, food and beverage packaging, and the assembly of automotive engine parts, the quality of the seals directly affects production safety, product quality, and environmental protection. Poor sealing can lead to leaks, causing safety accidents, material losses, environmental pollution, and even affecting product performance and lifespan.

[0003] The existing technology has the following defects or problems: Existing technology, publication number CN219369030U, discloses an automatic sealing plug device, including: a push rod and a top sleeve fitted outside the push rod; wherein, the push rod is cylindrical, with a first hole at its upper end that can be screwed onto a leak test fixture cylinder; a central hole is located at a predetermined distance at the lower end of the first hole in the push rod, and a spring is placed in the central hole; a pull rod is installed in the central hole at the lower end of the push rod, and a pin hole is located at the upper end of the pull rod for pressing the spring; the top sleeve is a cylindrical structure larger than the push rod, and is a hollow structure with open upper and lower ends that can be fitted outside the push rod. This utility model, under the action of the cylinder, can not only effectively seal the bushing hole to prevent air leakage, eliminating the quality hazard of inaccurate data testing during workpiece leakage testing; but also avoids the risk of product quality degradation when the workpiece leaks, and also avoids economic losses to the company and customers.

[0004] The aforementioned equipment can effectively seal the bushing hole to prevent air leakage during use, eliminating the quality hazard of inaccurate data testing of bushing hole leakage during workpiece leakage testing. However, the aforementioned technology cannot adjust the size of the groove where the rubber ring is located, which means that the technology cannot install rubber rings of different diameters. This means that when sealing the bushing hole of workpieces with different diameters, the entire equipment needs to be replaced, resulting in increased costs. Therefore, an automatic sealing plug device is proposed to solve the above problems.

[0005] It should be noted that the above content falls within the inventor's technical knowledge and does not necessarily constitute prior art. Utility Model Content

[0006] In view of the shortcomings of the existing technology, this utility model provides an automatic sealing plug device, which solves the existing problems.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an automatic sealing plug device, including a cylinder, an output shaft slidably connected to the right side of the cylinder, a push rod abutting the right side of the output shaft, a pressure rod slidably connected to the right side of the push rod, a moving rod slidably connected to the right side of the pressure rod, a limit block fixedly connected to the right side of the moving rod, a rubber ring sleeved on the outer periphery of the pressure rod, a spring fixedly connected inside the push rod, a groove on the side of the pressure rod facing the limit block, and an adjustment component inside the moving rod;

[0008] The adjusting assembly includes a threaded rod rotatably connected inside the movable rod. A sliding block is threadedly connected to the left side of the threaded rod. Two support frames are fixedly connected to the left side of the sliding block. A connecting rod is rotatably connected to the left side of each of the two support frames. A sliding frame is rotatably connected to the other end of each of the two connecting rods. A sliding rod is fixedly connected to the left side of each of the two sliding frames. A fixed frame is fixedly connected to the left side inside the movable rod. A sliding rod is fixedly connected to both ends of the fixed frame. The two sliding rods are slidably connected to the outer periphery of the two sliding rods respectively.

[0009] The output shaft is equipped with mounting components.

[0010] As a preferred embodiment of this utility model, the mounting assembly includes two locking blocks, both of which are slidably connected inside the output shaft. A pull rod is fixedly connected to one side of each locking block, and a spring is sleeved on the outer periphery of each pull rod. A mounting block is fixedly connected to the left side of the top rod, and two mounting grooves are formed on the outer periphery of the mounting block. The two locking blocks are respectively engaged in the two mounting grooves.

[0011] As a preferred embodiment of this utility model, the output shaft has two limiting grooves inside, and the two pull rods are slidably connected inside the two limiting grooves respectively.

[0012] As a preferred embodiment of this utility model, the pressure rod has multiple evenly distributed slots inside, and the two sliding rods are respectively engaged in two of the slots.

[0013] As a preferred embodiment of this utility model, two sliders are fixedly connected to the outer periphery of the moving rod, and two sliding grooves are opened inside the pressure rod, with the two sliders slidably connected inside the two sliding grooves respectively.

[0014] As a preferred embodiment of this utility model, a hexagonal handle is fixedly connected to the right side of the threaded rod, and the hexagonal handle is rotatably connected to the right side of the movable rod.

[0015] As a preferred technical solution of this utility model, each of the two pull rods is fixedly connected to a limiting plate on one side away from each other, and each of the two limiting plates is fixedly connected to a handle on the other end.

[0016] Compared with the prior art, the present invention provides an automatic sealing plug device, which has the following beneficial effects:

[0017] 1. This automatic sealing plug device utilizes the cooperation between a moving rod, a threaded rod, a sliding block, a support frame, a connecting rod, a sliding frame, a sliding rod, a fixed frame, a sliding rod, a pressure rod, and a slot. Rotating the hexagonal handle drives the threaded rod to rotate, causing the sliding block to move left and right on the threaded rod. The sliding block, through the support frame, drives the connecting rod to move, which in turn moves the sliding frame. The sliding frame then drives the sliding rod to slide on the sliding rod, allowing the sliding rod to retract into the moving rod, thus adjusting the position of the moving rod and changing the length of the groove between the pressure rod and the limiting block. Reversing the hexagonal handle resets the sliding block, allowing the sliding rod to be inserted into the corresponding slot for fixing. Appropriate length rubber rings can be selected and installed in the adjusted groove to adapt to different lengths, greatly improving the device's sealing adaptability to bushing holes of different sized workpieces. This avoids frequent replacements of the entire device due to mismatched rubber rings and grooves, effectively reducing costs and improving production efficiency.

[0018] 2. This automatic sealing plug device, through the cooperation of the output shaft, locking block, pull rod, spring 2, mounting block, mounting groove, limit groove, limit plate, and handle, allows for quick installation of the push rod by inserting the mounting block on the left side of the push rod into the output shaft when the push rod needs to be installed. The mounting groove on the mounting block aligns with the locking block, and under the action of spring 2, the locking block engages in the mounting groove. When disassembly is required, pulling the handle moves the pull rod outward, causing the locking block to disengage from the mounting groove, overcoming the elasticity of spring 2. The push rod can then be removed from the output shaft. The operation is simple and convenient, facilitating the installation, maintenance, and replacement of the sealing plug device, improving equipment maintenance convenience. It also allows for the rapid replacement of different specifications of sealing plug devices or cylinders according to different production tasks, enhancing the flexibility and versatility of the equipment.

[0026] 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.

[0027] Please see Figure 1 - Figure 4 In this embodiment: the automatic sealing plug device includes a cylinder 1, an output shaft 2 slidably connected to the right side of the cylinder 1, a push rod 3 abutting the right side of the output shaft 2, a pressure rod 4 slidably connected to the right side of the push rod 3, a moving rod 5 slidably connected to the right side of the pressure rod 4, a limit block 6 fixedly connected to the right side of the moving rod 5, a rubber ring 7 sleeved on the outer periphery of the pressure rod 4, a spring 8 fixedly connected inside the push rod 3, and a groove 9 on the side of the pressure rod 4 facing the limit block 6;

[0028] Specifically, cylinder 1 serves as the power source, which is existing technology. Output shaft 2 is used to push push rod 3 to move to the right. Pressure rod 4 is slidably connected to push rod 3 and can slide relative to push rod 3 on the right side. Rubber ring 7 sleeved on the outer circumference of pressure rod 4 is used to contact the workpiece bushing hole to achieve a sealing function. Moving rod 5 is slidably connected to pressure rod 4, and the limiting block 6 fixed on its right side cooperates with pressure rod 4 to form a groove 9 for accommodating rubber ring 7. Spring 8 is located inside push rod 3 and plays a certain role in buffering and resetting. When push rod 3 is subjected to external force, spring 8 can absorb energy to a certain extent and help push rod 3 return to its initial position after the force disappears.

[0029] The movable rod 5 is equipped with an adjustment component, which includes a threaded rod 10. The threaded rod 10 is rotatably connected inside the movable rod 5. A sliding block 11 is threadedly connected to the left side of the threaded rod 10. Two support frames 12 are fixedly connected to the left side of the sliding block 11. A connecting rod 13 is rotatably connected to the left side of each of the two support frames 12. A sliding frame 14 is rotatably connected to the other end of each of the two connecting rods 13. A sliding rod 15 is fixedly connected to the left side of each of the two sliding frames 14. A fixed frame 16 is fixedly connected to the left side of the movable rod 5. A sliding rod 17 is fixedly connected to both ends of the fixed frame 16. The two sliding rods 15 are slidably connected to the outer periphery of each of the two sliding rods 17. The pressure rod 4 has multiple evenly distributed slots 18 inside. The two sliding rods 15 are respectively engaged in two of the slots 18. Two sliders 20 are fixedly connected to the outer periphery of the movable rod 5. Two sliding grooves 21 are opened inside the pressure rod 4. The two sliders 20 are slidably connected to the two sliding grooves 21. A hexagonal handle 19 is fixedly connected to the right side of the threaded rod 10. The hexagonal handle 19 is rotatably connected to the right side of the movable rod 5.

[0030] Specifically, the threaded rod 10 can rotate freely inside the moving rod 5, and its rotation will drive the sliding block 11, which is threadedly connected to it, to move left and right. The sliding block 11 serves as a connecting component, and the support frame 12 fixed on its left side is used to connect the connecting rod 13. When the sliding block 11 moves, it drives the connecting rod 13 to move through the support frame 12. The connecting rod 13 is rotatably connected to the support frame 12 and the sliding frame 14 at both ends, respectively, to transmit motion and force. The sliding rod 15, fixed on the other side of the sliding frame 14, slides on the sliding rods 17 at both ends of the fixed frame 16. The sliding rods 17 provide stable guidance for the sliding rod 15, ensuring the accurate movement direction of the sliding rod 15. The slot 18 inside the pressure rod 4 engages with the sliding rod 15 to fix the relative position of the pressure rod 4 and the moving rod 5. When it is necessary to adjust the length of the groove 9, the sliding rod 15 is disengaged from the slot 18, adjusted, and then engaged back into the corresponding slot 18. The slider 20 on the outer periphery of the moving rod 5 slides in conjunction with the sliding groove 21 inside the pressure rod 4, ensuring that the moving rod 5 slides smoothly and accurately within the pressure rod 4. The hexagonal handle 19 facilitates the operator's rotation of the threaded rod 10.

[0031] Please see Figure 2 , Figure 5 and Figure 6In this embodiment, an installation assembly is provided inside the output shaft 2. The installation assembly includes two locking blocks 25, both of which are slidably connected inside the output shaft 2. A pull rod 26 is fixedly connected to the side of the two locking blocks 25 that is away from each other. A spring 27 is sleeved on the outer periphery of the two pull rods 26. An installation block 22 is fixedly connected to the left side of the top rod 3. Two installation grooves 23 are opened on the outer periphery of the installation block 22. The two locking blocks 25 are respectively locked into the two installation grooves 23. Two limiting grooves 24 are opened inside the output shaft 2. The two pull rods 26 are slidably connected to the two limiting grooves 24 that are away from each other. A limiting plate 28 is fixedly connected to the other end of the two limiting plates 28. A handle 29 is fixedly connected to the other end of the two limiting plates 28.

[0032] Specifically, the locking block 25 slides inside the output shaft 2, cooperating with the mounting block 22 on the left side of the push rod 3 to achieve quick installation and removal of the push rod 3 from the output shaft 2. When the locking block 25 is engaged in the mounting groove 23 on the outer periphery of the mounting block 22, the push rod 3 is firmly connected to the output shaft 2; when the locking block 25 is disengaged from the mounting groove 23, the push rod 3 can be removed from the output shaft 2. The pull rod 26 is fixedly connected to the locking block 25 and is used to pull the locking block 25 to slide inside the output shaft 2. The spring 27 is sleeved on the outer periphery of the pull rod 26. In the compressed state, the locking block 25 is provided with elastic force in the direction of the mounting groove 23, ensuring that the locking block 25 is tightly engaged with the mounting groove 23 under normal conditions. The limiting groove 24 inside the output shaft 2 provides a sliding track for the pull rod 26, limiting the movement direction of the pull rod 26 and ensuring that it stably pulls the locking block 25. The limiting plate 28 is fixed on the opposite side of the pull rod 26, and its function is to prevent the pull rod 26 from being pulled too much and falling off. The handle 29 is connected to the other end of the limiting plate 28, making it convenient for the operator to pull the pull rod 26.

[0033] The working principle and usage process of this utility model are as follows: When it is necessary to select a rubber ring 7 of appropriate length according to the size of the workpiece bushing hole and adjust the length of the groove 9, the limiting block 6 can be unscrewed first. Then, the operator can rotate the hexagonal hand 19 with a tool to make the threaded rod 10 rotate inside the moving rod 5. The rotation of the threaded rod 10 will cause the sliding block 11 to move to the left on the threaded rod 10. The movement of the sliding block 11 drives the connecting rod 13 to move through the support frame 12. The connecting rod 13 then pushes the sliding frame 14 to move to the left. The sliding frame 14 will drive the sliding rod 15 to slide inside the moving rod 5 on the sliding rod 17. The movement causes the sliding rod 15 to disengage from the slot 18 inside the pressure rod 4. Then, according to the length of the rubber ring 7, the moving rod 5 is moved to a suitable position to change the length of the groove 9 between the pressure rod 4 and the limiting block 6. Then, the hexagonal handle 19 is reversed to move the sliding block 11 to the right, thereby driving the sliding rod 15 to move to the right until the sliding rod 15 is engaged in the corresponding slot 18, completing the adjustment of the length of the groove 9. Next, a rubber ring 7 of a suitable length is installed in the groove 9, and the limiting block 6 is screwed back on to achieve the adaptation of rubber rings 7 of different lengths to meet the sealing requirements of bushing holes of workpieces of different sizes.

[0034] When installing the push rod 3, the operator inserts the mounting block 22 on the left side of the push rod 3 into the output shaft 2, aligning the mounting groove 23 on the mounting block 22 with the locking block 25 inside the output shaft 2. At this time, under the elastic force of the second spring 27, the locking block 25 is locked into the mounting groove 23, realizing the quick installation of the push rod 3 and the output shaft 2. When it is necessary to remove the push rod 3, the operator pulls the handle 29. The handle 29 drives the pull rod 26 to move away from the mounting block 22. The pull rod 26 drives the locking block 25 to slide inside the output shaft 2 and disengage from the mounting groove 23. During this process, the elastic force of the second spring 27 is overcome. After the locking block 25 is completely disengaged from the mounting groove 23, the push rod 3 can be removed from the output shaft 2. The operation is simple and convenient, making it easy to install, maintain and replace the sealing plug device.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is 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.
