Description
Technical Field
[0001] This utility model relates to the field of coil spring technology, and in particular to a coil spring with an anti-misalignment structure. Background Technology
[0002] As an indispensable elastic energy storage component in mechanical systems, coil springs occupy an important position in industrial production, transportation, and consumer electronics due to their unique structural and performance advantages. With the continuous advancement of technology in various industries, the requirements for the performance and reliability of coil springs are becoming increasingly stringent, especially the stability under complex working conditions, which has become a key indicator. Existing coil springs can basically meet the needs of daily use, but there are still some shortcomings that need to be improved.
[0003] In actual transportation, the bumps of road freight, the vibrations of rail transport, and the changes in air pressure during air transport can all impact coil springs. Once the coil spring is affected by external vibrations, the middle of the coil spring is prone to misalignment. This misalignment not only causes the coil spring to become entangled, but also changes the spacing between the coils, damaging the original mechanical properties of the coil spring. Traditional coil spring packaging often uses simple plastic bags or cardboard boxes, which can only play a basic role in dust prevention and protecting the appearance, and cannot resist the vibration and impact during transportation. Even if some products are wrapped with cushioning materials, it is difficult to solve the problem of misalignment of the coil spring under vibration from a structural perspective. Therefore, we propose a coil spring with an anti-misalignment structure to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to provide a coil spring with an anti-misalignment structure to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a coil spring with an anti-misalignment structure, comprising a housing and a coil spring placed inside the housing. A positioning post is fixed in the center of the housing, and a rotating seat is fixed on the left side of the housing. A rotating connecting rod is rotatably connected inside the rotating seat. A cover plate is installed outside the rotating connecting rod, and a horizontal handle is installed on the left side of the cover plate. Guide rails are installed on both sides of the inner wall of the housing, and sliding rods are fixed inside each guide rail. Two sets of sliding sleeves are slidably connected to the outside of each set of sliding rods. The opposite ends of the sliding sleeves in the two sets of guide rails are connected to limit pressure plates through connecting rods. Pull handles are installed on the opposite ends of the limit pressure plates. First return springs are provided at both ends of the sliding rods in the two sets of guide rails. Sleeve frames are installed at both the front and rear ends of the housing. The two sets of limit pressure plates pass through the sleeve frames, and locking components are installed on both sides of the two sets of limit pressure plates.
[0006] As an improved technical solution, the locking assembly includes a movable inner cavity, guide rods, movable plates, locking tongues, and a second return spring. The limiting pressure plate has movable inner cavities on both the left and right sides. Two sets of guide rods are provided in each movable inner cavity. Movable plates are provided outside the two sets of guide rods. Locking tongues are fixed at opposite ends of the two sets of movable plates. A second return spring is wound around the outside of the two sets of guide rods.
[0007] As an improved technical solution, protrusions are installed on both the upper and lower sides of the limiting pressure plate, and slots corresponding to the protrusions are opened on both the upper and lower sides of the inner wall of the sleeve frame.
[0008] As an improved technical solution, the two ends of the first return spring outside the slide rod are respectively connected to the outer wall of the slide sleeve and the inner wall of the guide rail, and the slide sleeve is elastically connected to the inner wall of the guide rail through the first return spring.
[0009] As an improved technical solution, the outer wall of the limiting pressure plate is fully fitted with the inner wall of the sleeve frame.
[0010] As an improved technical solution, both sets of locking tongues on the limiting pressure plate are designed in an inclined shape, and the outer walls of both sets of locking tongues are polished.
[0011] As an improved technical solution, the movable plate is provided with a sliding groove corresponding to the two sets of guide rods, and the movable plate is slidably connected to the two sets of guide rods through the sliding groove.
[0012] After adopting the above technical solution, the beneficial effects of this utility model are:
[0013] I. This utility model has two sets of laterally movable limiting pressure plates installed inside the casing. The first return spring outside the slide rod releases its elastic force to push the two sets of slide sleeves to move in opposite directions. The two sets of limiting pressure plates can move to the top of the coil spring under the drive of the slide sleeves, so that the two sets of limiting pressure plates can press the coil spring inside the casing, thereby effectively preventing the coil spring from being misaligned after being vibrated. In addition, the flip-up cover plate outside the casing can seal the top of the casing, preventing external objects from contacting the coil spring inside the casing during transportation.
[0014] II. This utility model features retractable locking tongues on both sides of the limiting pressure plate. When the two sets of limiting pressure plates open outward, and the limiting pressure plates cause the two sets of locking tongues to leave the inside of the sleeve frame, the second return springs outside the two sets of guide rods release their elasticity, pushing the movable plate outward. This allows the two sets of locking tongues to pop outward from the movable inner cavity, enabling the two sets of locking tongues to limit the limiting pressure plate towards the inside of the sleeve. This facilitates the removal and placement of the coil spring inside the sleeve without the need to continuously pull the handle outside the limiting pressure plate, thus improving the convenience of using the device.

[0027] Figures 1 to 6 As shown, this embodiment provides a coil spring with an anti-misalignment structure, including a housing 1 and a coil spring 3 placed inside the housing 1. A positioning post 2 is fixed in the center of the housing 1, and a rotating base 4 is fixed on the left side of the housing 1. A rotating connecting rod 5 is rotatably connected inside the rotating base 4. A cover plate 6 is installed on the outside of the rotating connecting rod 5. The cover plate 6 can be quickly fixed to the surface of the housing 1 by a snap fastener. A horizontal handle 7 is installed on the left side of the cover plate 6. Guide rails 8 are installed on both sides of the inner wall of the housing 1, and a sliding rod is fixed inside each of the guide rails 8. 9. Two sets of sliding sleeves 10 are slidably connected to the outside of the two sets of sliding rods 9. The opposite ends of the sliding sleeves 10 in the two sets of guide rails 8 are connected to limit pressure plates 12 through connecting rods 11. Pull handles 13 are installed on the opposite ends of the two sets of limit pressure plates 12. The two ends of the sliding rods 9 in the two sets of guide rails 8 are provided with first return springs 14. The front and rear ends of the sleeve box 1 are both equipped with sleeve frames 15. The two sets of limit pressure plates 12 pass through the inside of the sleeve frames 15. Locking components are installed on both sides of the two sets of limit pressure plates 12.
[0028] By installing two sets of laterally movable limiting pressure plates 12 inside the housing 1, when it is necessary to place the coil spring 3, the handles 13 on the two sets of limiting pressure plates 12 can be pulled in opposite directions, causing the two sets of limiting pressure plates 12 to drive the sliding sleeve 10 to move along the outside of the sliding rod 9. During the movement, the sliding sleeve 10 compresses the first return spring 14 outside the sliding rod 9. When the two sets of limiting pressure plates 12 are pulled apart to a suitable distance, the coil spring 3 can be placed inside the housing 1. Then, the handles 13 on the outside of the two sets of limiting pressure plates 12 can be released. The pulling force causes the first return spring 14 outside the slide rod 9 to release its elastic force and push the two sets of slide sleeves 10 to move in opposite directions. This allows the two sets of limiting pressure plates 12 to move to the top of the coil spring 3 under the drive of the slide sleeves 10. The two sets of limiting pressure plates 12 then press down on the coil spring 3 inside the box 1, which effectively prevents the coil spring 3 from becoming misaligned after being vibrated. In addition, the flip-out cover plate 6 outside the box 1 allows the cover plate 6 to seal the top of the box 1, preventing external objects from contacting the coil spring 3 inside the box 1 during transportation.
[0029] In other embodiments, the locking assembly includes a movable inner cavity 18, guide rods 19, movable plates 20, locking tongues 21, and a second return spring 22. The limiting pressure plate 12 has movable inner cavities 18 on both the left and right sides. Two sets of guide rods 19 are provided in each movable inner cavity 18. Movable plates 20 are provided outside the two sets of guide rods 19. Locking tongues 21 are fixed at opposite ends of the two sets of movable plates 20. The second return spring 22 is wound around the outside of the two sets of guide rods 19.
[0030] By providing retractable locking tongues 21 on both sides of the limiting pressure plate 12, when the two sets of limiting pressure plates 12 open outward, the two sets of limiting pressure plates 12 can drive the two sets of locking tongues 21 to move to the rear end of the sleeve frame 15. Subsequently, the continued movement of the limiting pressure plates 12 causes the two sets of locking tongues 21 to be squeezed, driving the movable plate 20 to move inward along the guide rod 19 in the movable inner cavity 18. During the movement, the movable plate 20 squeezes the second return spring 22 outside the guide rod 19. When the limiting pressure plate 12 opens outward, the two sets of locking tongues 21 move inward. After the two sets of locking tongues 21 are driven away from the inside of the sleeve frame 15, the second return spring 22 outside the two sets of guide rods 19 can release its elasticity to push the movable plate 20 outward, so that the two sets of locking tongues 21 can pop outward from the movable inner cavity 18, so that the two sets of locking tongues 21 can limit the limit pressure plate 12 to the inside of the sleeve box 1, thereby facilitating the taking and placing of the coil spring 3 inside the sleeve box 1 without having to continuously pull the handle 13 outside the limit pressure plate 12, thus improving the convenience of using the device.
[0031] In other embodiments, protrusions 16 are installed on both the upper and lower sides of the limiting pressure plate 12, and slots 17 corresponding to the protrusions 16 are opened on both the upper and lower sides of the inner wall of the sleeve frame 15.
[0032] This design allows the slot 17 on the sleeve 15 to work with the protrusion 16 on the limiting pressure plate 12 to create opposing elastic forces on the limiting pressure plate 12, thereby effectively preventing the limiting pressure plate 12 from detaching from the sleeve 15 and ensuring that the limiting pressure plate 12 can be used normally.
[0033] In other embodiments, the two ends of the first return spring 14 outside the slide rod 9 are respectively connected to the outer wall of the slide sleeve 10 and the inner wall of the guide rail 8, and the slide sleeve 10 is elastically connected to the inner wall of the guide rail 8 through the first return spring 14.
[0034] This design allows the two sets of first return springs 14 outside the slide rod 9 to continuously apply opposing elastic forces to the two sets of sliding sleeves 10 outside the slide rod 9, so that the two sets of slide rods 9 can drive the two sets of limiting pressure plates 12 to move in opposite directions into the sleeve 1.
[0035] In other embodiments, the outer wall of the limiting pressure plate 12 is fully fitted with the inner wall of the sleeve frame 15;
[0036] This design effectively prevents the limiting pressure plate 12 from shaking inside the sleeve frame 15, thereby improving the stability of the limiting pressure plate 12 within the sleeve frame 15.
[0037] In other embodiments, both sets of latches 21 on the limiting pressure plate 12 are designed in an inclined shape, and the outer walls of both sets of latches 21 are polished.
[0038] With this design, when the two sets of locking tongues 21 move to the outside of the sleeve frame 15, the friction between the two sets of locking tongues 21 and the outside of the sleeve frame 15 can be effectively reduced, so that the locking tongues 21 can drive the movable plate 20 to retract into the movable inner cavity 18.
[0039] In other embodiments, the movable plate 20 is provided with a sliding groove corresponding to the two sets of guide rods 19, and the movable plate 20 is slidably connected to the two sets of guide rods 19 through the sliding groove;
[0040] This design allows the movable plate 20 to slide smoothly and steadily along the surfaces of the two sets of guide rods 19, thus ensuring the stability of the movable plate 20 during movement.
[0041] The electrical components mentioned in this article are all electrically connected to an external main controller and industrial power supply, and the main controller can be a conventional known device such as a computer that provides control.
[0042] 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.
