Description

Technical Field

[0001] This application relates to the field of construction auxiliary tools, and in particular to a tool for removing rubber caps. Background Technology

[0002] Before concrete pouring, formwork is erected on the construction site. Then, sleeves and tie rods are installed between the two formwork sections, with round frustum-shaped plastic plugs attached to both ends of the sleeves. The tie rods, inserted between the two formwork sections, secure the formwork; the sleeves are positioned outside the tie rods, with their outer walls in contact with the concrete, facilitating the removal of the tie rods; the plugs prevent concrete mortar from entering the sleeves, thus facilitating the subsequent removal of the tie rods.

[0003] The plug, also known as a rubber cap, is used during construction after the concrete has hardened. The formwork and tie rods need to be removed, and then the rubber cap needs to be taken off. However, the removal of the rubber cap is usually done manually. Because the outside of the rubber cap is in direct contact with the concrete, manually removing the rubber cap is time-consuming, labor-intensive, and inefficient. Summary of the Invention

[0004] To make the process of removing the rubber cap more time-saving and labor-saving, this application provides a rubber cap removal tool.

[0005] The cap removal tool provided in this application adopts the following technical solution:

[0006] A cap removal tool includes a housing, a movable rod slidably disposed on the housing, a hook disposed at the end of the movable rod, a first spring disposed between the movable rod and the housing, and a drive assembly disposed within the housing. The movable rod is slidably disposed on the housing along its own length direction, the drive assembly is used to drive the movable rod to slide out of the housing, and the first spring causes the movable rod to tend to slide closer to the inside of the housing.

[0007] By adopting the above technical solution, when in use, the hook is aligned with the center hole of the cap, and the movable rod is positioned coaxially with the center hole of the cap. Then, the movable rod is extended by the drive assembly, and the hook at the end of the movable rod can be inserted into the center hole of the cap and hung on the inner wall of the center hole of the cap. Then, the drive assembly is released, and under the action of the first spring, the movable rod slides into the housing, and drives the hook to slide into the housing, thereby causing the cap on the hook to slide away from the wall, and the cap installed on the wall can be removed. Therefore, the process of removing the cap is relatively simple, saves time and effort, and helps to improve work efficiency.

[0008] Optionally, the drive assembly includes a driving rack, a driven rack, a gear, and a lever. The driving rack is slidably disposed within the housing along the length of the movable rod. The driven rack is disposed on the movable rod, and both the driving rack and the driven rack are parallel to the movable rod. The gear is rotatably disposed within the housing, and the driving rack and the driven rack mesh with the two sides of the gear, respectively. The lever is disposed on the driving rack, and one end of the lever extends out of the housing.

[0009] By adopting the above technical solution, the lever can be moved closer to the inside of the housing by moving the active rack closer to the inside of the housing. The active rack drives the gear to rotate, and the gear drives the driven rack to move away from the housing, thereby causing the movable rod to extend outward. The structure is simple, stable and reliable. Moreover, it is more convenient to operate because only the lever needs to be pulled.

[0010] Optionally, the housing is provided with a positioning cylinder made of transparent material, and the positioning cylinder has an opening on the side away from the housing, through which the hook can pass.

[0011] By adopting the above technical solution, during operation, the end face of the opening side of the positioning cylinder is pressed against the wall surface, and the hook is aligned with the center hole of the rubber cap. Then, the lever is pulled outward and released, and the hook can hook the rubber cap and then remove the rubber cap. Therefore, the positioning cylinder can ensure the force applied to the lever and ensure the sliding direction of the movable rod and the hook, which helps to improve the stability of the process of removing the rubber cap, thereby quickly removing the rubber cap.

[0012] Optionally, multiple hooks are provided, each hook is rotatably mounted on a movable rod, and a reset component is provided between the hook and the movable rod. The reset component causes the hook to tend to rotate away from the movable rod. A pulling component is provided inside the housing, and the pulling component causes the hook to tend to rotate towards the movable rod.

[0013] By adopting the above technical solution, after the cap is removed, it is hung on the hook. At this time, the movable rod is first slid away from the housing, allowing the hook to pass through the central hole of the cap. Then, by pulling the component, the hook is rotated towards the movable rod. The cap can then be pulled outwards without being obstructed by the hook, making it easy to remove the cap from the hook. Due to the rotating design of the hook, it can rotate towards the movable rod as it extends into the central hole of the cap, making it easier to insert. After insertion, when the movable rod drives the hook to move in the opposite direction, the reset component can rotate the hook away from the movable rod, causing the hook to hang on the inner wall of the central hole of the cap, thus facilitating the removal of the cap from the wall.

[0014] Optionally, the reset component includes a connecting block, a connecting rod, and a second spring. The connecting block is slidably disposed on the movable rod. The number of connecting rods is the same as the number of hooks. One end of the connecting rod is rotatably connected to the corresponding hook, and the other end of the connecting rod is rotatably connected to the connecting block. The second spring is connected between the connecting block and the movable rod, and the second spring causes the connecting block to tend to move towards the side closer to the hook.

[0015] By adopting the above technical solution, the second spring causes the connecting block to tend to move towards the side closer to the hook. Under the action of the connecting rod, the hook can tend to rotate away from the moving rod, that is, the hook tends to open outward. The setting of the connecting rod allows multiple hooks to rotate synchronously, and the distance between the end of each hook away from the moving rod and the moving rod is equal, thus helping to ensure the hanging effect of the cap.

[0016] Optionally, the pulling component includes a connecting rope that connects the drive rack and the connecting block.

[0017] By adopting the above technical solution, after the rubber cap is removed from the wall, it is hung on the hook. At this time, the lever drives the active rack to move away from the rubber cap. The movable rod first moves the hook, allowing the hook to pass through the center hole of the rubber cap. Then, as the lever moves, the connecting rope is gradually taut. The continued movement of the lever will drive the connecting block to move through the connecting rope. The connecting block moves away from the hook. Under the action of the connecting rod, the hook will rotate towards the movable rod, causing the hook to retract. Then, the rubber cap can be removed. Therefore, the design of the connecting rope allows the hook to be retracted while the lever is being moved, thus simplifying the operation and improving work efficiency.

[0018] Optionally, a mounting block is slidably disposed inside the housing along the length direction of the movable rod, the first spring is connected between the movable rod and the mounting block, and an adjusting screw is rotatably disposed on the housing, the adjusting screw being parallel to the movable rod and threadedly connected to the mounting block.

[0019] By adopting the above technical solution, rotating the adjusting screw can drive the mounting block to slide, thereby adjusting the distance between the mounting block and the movable rod. This changes the length of the first spring under normal conditions, thereby adjusting the elastic force of the first spring. Adjusting it as needed helps to ensure the force of the hook on the rubber cap installed on the wall, adapting to different situations. While ensuring that the rubber cap can be removed, the force required to move the lever can be reduced, making the operation more effortless.

[0020] Optionally, the movable rod is provided with a guide assembly, which includes a guide plate disposed on the movable rod and balls disposed on the guide plate. Multiple guide plates are provided, which are arranged around the periphery of the movable rod and are parallel to the movable rod. Multiple balls are provided and are spaced apart on the guide plate along the length direction of the guide plate. The balls are located on the side of the guide plate away from the movable rod.

[0021] By adopting the above technical solution, after removing the cap from the wall, the hook is passed through the central hole of the cap by turning the lever, and the hook is retracted by the connecting rope. At this time, the cap is fitted on the outside of the guide plate, and the ball bearing on the outside of the guide plate abuts against the inner wall of the central hole of the cap. Then, the cap can be pulled out directly. During the process of pulling the cap out, the guide plate plays a guiding role, thereby preventing the cap from getting caught on the hook again during the process of pulling out, thus making the process of pulling out the cap more convenient and faster, and helping to further improve work efficiency. The ball bearing reduces the friction encountered by the cap during the sliding process, making the process of pulling out the cap less strenuous.

[0022] Optionally, the guide plate is slidably disposed on the movable rod along the radial direction of the movable rod. The movable rod is provided with an adjustment component, which includes an adjustment block, a connecting ring, and a connecting rod. The adjustment block is threadedly connected to the movable rod, and the connecting ring is rotatably disposed on the adjustment block. The number of connecting rods is the same as the number of guide plates. One end of the connecting rod is rotatably connected to the corresponding guide plate, and the other end of the connecting rod is rotatably connected to the connecting ring.

[0023] By adopting the above technical solution, rotating the adjusting block allows it to move along the length of the movable rod, thereby driving the connecting ring to move. When the connecting ring moves, it drives the connecting rod to rotate, causing the guide plate to move closer to or further away from the movable rod. Adjusting the distance between the guide plate and the movable rod allows the device to be adapted to the center holes of rubber caps of different diameters, thus expanding its application range.

[0024] Optionally, a cover plate is movably disposed on the housing, and the cover plate is located on one side of the adjusting block.

[0025] By adopting the above technical solution, after the cover is opened, it is convenient to rotate the adjusting block to adjust the position of the guide plate.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. Align the hook with the center hole of the rubber cap installed on the wall, then move the lever to move the movable rod closer to the hook. The movable rod will cause the hook to extend into the center hole of the rubber cap. After releasing the lever, the first spring will cause the movable rod to move the hook in the opposite direction. The hook will hang on the inner wall of the center hole of the rubber cap. As the hook moves, the rubber cap can be moved away from the wall, thus removing the rubber cap. The process of removing the rubber cap is simpler, saving time and effort.

[0028] 2. After removing the cap from the wall, attach the cap to the hook. Then, move the lever to move the hook and let it pass through the center hole of the cap. At the same time, the connecting rope can move the connecting block to retract the hook, making it easy to remove the cap from the hook.

[0029] 3. The guide component guides the outward sliding of the cap, preventing it from getting caught on the retracted hook, thus making the process of pulling out the cap easier and faster, and helping to further improve work efficiency. Attached Figure Description

[0036] The present application will be further described in detail below with reference to the accompanying drawings.

[0037] This application discloses a tool for removing rubber caps. (Refer to...) Figure 1 and Figure 2 The cap removal tool includes a housing 1, a positioning cylinder 6, a movable rod 2, a hook 3, a first spring 4, and a drive assembly 5. The housing 1 is a slender cylinder with an internal cavity; a gripping rod 14 is welded to the outer wall of the housing 1 for easy handling by the operator. The positioning cylinder 6 is fixedly connected to one end of the housing 1. The positioning cylinder 6 is frustoconical, with its axis parallel to the length of the housing 1. An opening is provided on the side of the positioning cylinder 6 away from the housing 1, and the positioning cylinder 6 is connected to the interior of the housing 1. The positioning cylinder 6 is made of transparent plastic, allowing for easy observation of its internal structure. A guide block 15 is fixedly connected inside the housing 1. The guide block 15 has a guide hole, the axis of which is parallel to the length of the housing 1. The movable rod 2 slides through the guide hole, allowing one end of the movable rod 2 to slide within the housing 1. Four hooks 3 are located on the end of the movable rod 2 away from the housing 1, arranged in a circular array. The end of each hook 3 away from the movable rod 2 is pointed. A mounting block 9 is provided inside the housing 1 on one side of the guide block 15. A first spring 4 is connected between the end of the movable rod 2 and the mounting block 9. The first spring 4 is in a stretched state, so the first spring 4 causes the movable rod 2 to tend to slide closer to the inside of the housing 1. A drive assembly 5 is provided inside the housing 1 to drive the movable rod 2 to move away from the housing 1.

[0038] In use, the end of the positioning cylinder 6 away from the housing 1 is pressed against the wall 16, and the movable rod 2 is made coaxial with the center hole 171 of the rubber cap 17 installed on the wall 16. Then, the movable rod 2 is moved closer to the wall 16 by the drive assembly 5. When the movable rod 2 moves, it drives the hook 3 to move, so that the hook 3 moves into the center hole 171 of the rubber cap 17. At this time, the hook 3 is hooked on the inner wall of the center hole 171 of the rubber cap 17. Then, the drive assembly 5 is stopped. Under the action of the restoring force of the first spring 4, the movable rod 2 moves closer to the housing 1. The movable rod 2 drives the hook 3 to move, and the hook 3 drives the rubber cap 17 to move, thereby removing the rubber cap 17 from the wall 16.

[0039] Furthermore, referring to Figure 2The mounting block 9 is slidably disposed within the housing 1 along its length, thus the tension of the first spring 4 on the movable rod 2 is adjustable. An adjusting screw 10 is rotatably disposed on the wall surface of the housing 1 at the end away from the positioning cylinder 6. One end of the adjusting screw 10 is located outside the housing 1, and the other end is located inside the housing 1. The adjusting screw 10 is disposed along the length of the movable rod 2. A screw hole is provided on the mounting block 9, and the mounting block 9 and the adjusting screw 10 are threadedly connected. Therefore, rotating the adjusting screw 10 allows the mounting block 9 to slide, thereby adjusting the distance between the mounting block 9 and the end of the movable rod 2, causing a change in the initial tension length of the first spring 4, thus achieving the purpose of adjusting the elastic force.

[0040] The drive assembly 5 includes a driving rack 51, a driven rack 52, a gear 53, and a lever 54. Both the driving rack 51 and the driven rack 52 are arranged along the length of the housing 1. The driving rack 51 is slidably disposed within the housing 1 along its own length, the driven rack 52 is fixedly connected to the movable rod 2, and the gear 53 is rotatably disposed within the housing 1. The driving rack 51 and the driven rack 52 mesh with the two sides of the gear 53, respectively. Therefore, moving the driving rack 51 away from the wall 16 will drive the gear 53 to rotate, and the rotation of the gear 53 will drive the driven rack 52 to move towards the wall 16, thereby inserting the hook 3 at the end of the movable rod 2 into the central hole 171 of the cap 17. The lever 54 is fixedly connected to the active rack 51, and the lever 54 is perpendicular to the active rack 51. The end of the lever 54 away from the active rack 51 extends out of the housing 1. The housing 1 has a through hole for the lever 54 to pass through. The through hole is a strip-shaped hole and is set along the length direction of the housing 1, so as to facilitate the sliding of the lever 54.

[0041] After the cap 17 is removed, it hangs on the hook 3. To facilitate the removal of the cap 17 from the hook 3, the hook 3 is hinged to the movable rod 2. A pulling component 8 is provided on one side of the movable rod 2. The pulling component 8 can cause the hook 3 to rotate towards the side closer to the movable rod 2, thereby retracting the hook 3. A reset component 7 is also provided on the movable rod 2. The reset component 7 can cause the hook 3 to rotate away from the movable rod 2, thereby opening the hook 3.

[0042] Reference Figure 3The reset component 7 includes a connecting block 71, a connecting rod 72, and a second spring 73. The connecting block 71 is slidably sleeved on the outer wall of the movable rod 2 along its length. Four connecting rods 72 are provided, each corresponding to one of the four hooks 3. One end of the connecting rod 72 is hinged to the outer wall of the connecting block 71, and the other end is hinged to the corresponding hook 3. The hinge axes at both ends of the connecting rod 72 are parallel; therefore, when the connecting block 71 moves, it can drive the hook 3 to rotate through the connecting rod 72, thereby adjusting the state of the hook 3. A protrusion 21 is fixedly connected to one side of the hook 3 on the movable rod 2. The protrusion 21 is located on the side of the connecting block 71 away from the hook 3. The second spring 73 is connected between the protrusion 21 and the connecting block 71. The second spring 73 is in a compressed state, so the second spring 73 causes the connecting block 71 to tend to move away from the protrusion 21, thereby causing the hook 3 to tend to open outward. A retaining ring 22 is fixedly connected to the movable rod 2. Under normal conditions, the second spring 73 causes one side of the connecting block 71 to press against the retaining ring 22. The angle between the connecting rod 72 and the corresponding hook 3 in the length direction is a right angle. Therefore, when the connecting block 71 moves closer to the protrusion 21, the hook 3 gradually retracts; when the connecting block 71 moves away from the protrusion 21, the hook 3 gradually opens.

[0043] In addition, in the initial state, the distance between the end of the hook 3 away from the movable rod 2 and the movable rod 2 is greater than the radius of the central hole 171 of the cap 17. Therefore, after the hook 3 is inserted into the central hole 171 of the cap 17, the hook 3 can be smoothly hung on the inner wall of the central hole 171, thereby pulling the cap 17 off the wall 16.

[0044] Reference Figure 4 The pulling component 8 includes a support rod 82 and a connecting rope 81. The support rod 82 is fixedly connected to the end of the drive rack 51 away from the hook 3. One end of the connecting rope 81 is fixedly connected to the end of the support rod 82 away from the drive rack 51, and the other end of the connecting rope 81 is fixedly connected to the connecting block 71. The connecting rope 81 is flexible but not elastic.

[0045] After removing the cap 17 from the wall 16, the cap 17 is hung on the hook 3; at this time, the movable rod 2 and the hook 3 are in the initial position, and the connecting rope 81 is in a slack state. Then, hold the cap 17 and pull the lever 54 to move the active rack 51 closer to the inside of the housing 1. The active rack 51 drives the support rod 82 to move; at the same time, the driven rack 52 drives the movable rod 2 to move away from the housing 1, and the connecting block 71 moves with the movable rod 2; since the connecting block 71 and the support rod 82 move in opposite directions, the two ends of the connecting rope 81 move away from each other, and the connecting rope 81 is gradually unfolded. When the movable rod 2 moves, it also drives the hook 3 to move. After the hook 3 passes through the center hole 171 of the cap 17, the connecting rope 81 can be taut. Then, as the lever 54 moves, the support rod 82 can drive the connecting block 71 to move through the taut connecting rope 81, causing the connecting block 71 to move relative to the movable rod 2 towards the side closer to the housing 1. As a result, the connecting block 71 drives the hook 3 to rotate towards the side closer to the movable rod 2 through the connecting rod 72, and the hook 3 retracts. When the lever 54 moves to its end, the hook 3 is in the retracted state. At this time, moving the cap 17 away from the housing 1 will allow the cap 17 to slide out smoothly.

[0046] To make the process of sliding out the cap 17 easier, refer to... Figure 4 and Figure 5 A guide assembly 11 is provided on the movable rod 2. The guide assembly 11 includes guide plates 111 and ball bearings 112. Four guide plates 111 are provided and are arranged around the movable rod 2. The guide plates 111 are long and thin strips, and their length direction is parallel to the length direction of the movable rod 2. Multiple ball bearings 112 are provided and are evenly spaced along the length direction of the guide plates 111. The ball bearings 112 are located on the side of the guide plate 111 away from the movable rod 2. The ball bearings 112 can abut against the inner wall of the center hole 171 of the cap 17. Therefore, during the process of the cap 17 sliding outward, the guide plates 111 and the ball bearings 112 can play a guiding role, preventing the cap 17 from being caught again by the retracted hook 3 when sliding, making the sliding process of the cap 17 simpler and faster.

[0047] Furthermore, the guide plate 111 is slidably disposed on the movable rod 2 along the radial direction of the movable rod 2, and the distance between each guide plate 111 and the movable rod 2 is equal. Therefore, the position of the guide plate 111 is adjustable, so that the guide assembly 11 can guide the caps 17 of different sizes. A limiting rod 1111 is fixedly connected to the side of the guide plate 111 near the movable rod 2. The limiting rod 1111 is perpendicular to the guide plate 111. A connecting strip 23 is welded to the part of the movable rod 2 corresponding to the guide plate 111. The connecting strip 23 is disposed along the length direction of the movable rod 2. A limiting hole is opened on the connecting strip 23, and the limiting rod 1111 slides through the corresponding limiting hole, so that the guide plate 111 is slidably disposed on the movable rod 2.

[0048] The movable rod 2 is equipped with an adjusting component 12 for adjusting the position of the guide plate 111. The adjusting component 12 includes an adjusting block 121, a connecting ring 122, and a connecting rod 123. The adjusting block 121 is a cylindrical block and is coaxially sleeved on the outer wall of the movable rod 2. The adjusting block 121 has a threaded hole, and the movable rod 2 has an external thread at a position corresponding to the adjusting block 121, so that the adjusting block 121 and the movable rod 2 are threadedly connected. The connecting ring 122 is coaxially sleeved on the outer wall of the adjusting block 121, and a limit block is fixedly connected to the inner wall of the connecting ring 122. A limit groove is provided around the outer wall of the adjusting block 121, and the limit block is engaged in the limit groove, so that the connecting ring 122 is rotatably mounted on the outer wall of the adjusting block 121 around its own axis. Four connecting rods 123 are provided, each corresponding to one of the four guide plates 111. One end of each connecting rod 123 is hinged to a connecting ring 122, and the other end is hinged to the corresponding guide plate 111, with the hinge axes at both ends of the connecting rod 123 being parallel. Therefore, rotating the adjusting block 121 allows it to slide along the movable rod 2. The adjusting block 121 drives the connecting ring 122 to slide, and the sliding of the connecting ring 122 can drive the guide plate 111 to move via the connecting rod 123, thereby synchronously adjusting the distance between each guide plate 111 and the movable rod 2 to accommodate different sizes of rubber caps 17.

[0049] For ease of rotating the adjusting block 121, refer to... Figure 1 and Figure 2 A cover plate 13 is hinged to one side of the adjusting block 121 on the housing 1. Therefore, when it is necessary to adjust the position of the guide plate 111, simply open the cover plate 13 and rotate the adjusting block 121 for adjustment.

[0050] The implementation principle of the tool for removing a rubber cap 17 in this embodiment is as follows: Holding the lever 14, first press the end face of the opening side of the positioning cylinder 6 against the wall 16, making the movable rod 2 and the central hole 171 of the rubber cap 17 installed on the wall 16 coaxial. Then slide the lever 54 away from the wall 16. The lever 54 drives the active rack 51 to move, the active rack 51 drives the gear 53 to rotate, the gear 53 drives the driven rack 52 to move, and the driven rack 52 drives the movable rod 2 to move closer to the wall 16. The hook 3 at the end of the movable rod 2 enters the central hole 171 of the rubber cap 17. When entering the central hole 171, the hook 3 rotates towards the side closer to the movable rod 2, and the end of the hook 3 away from the movable rod 2 abuts against the inner wall of the central hole 171, thus allowing the hook 3 and the movable rod 2 to slide smoothly inward.

[0051] As the hook 3 enters the center hole 171 of the cap 17, the active rack 51 drives the support rod 82 to move away from the wall 16, and the movable rod 2 drives the connecting block 71 to move closer to the wall 16. Consequently, the two ends of the connecting rope 81 move away from each other, and the slack connecting rope 81 gradually unfolds. After the hook 3 has moved a certain distance in the center hole 171 of the cap 17, the connecting rope 81 becomes taut. At this point, as the lever 54 continues to move, the support rod 82 drives the connecting block 71 to move away from the wall 16 via the taut connecting rope 81. Therefore, the connecting block 71 drives the hook 3 to rotate closer to the movable rod 2 via the connecting rod 72, and the hook 3 is retracted. When the lever 54 reaches its end, the hook 3 is in a retracted state, and the end of the hook 3 away from the movable rod 2 does not contact the inner wall of the center hole 171 of the cap 17. Then, release lever 54. Under the action of the first spring 4, movable lever 2 drives hook 3 to move away from wall 16. At this time, movable lever 2 drives driven rack 52 to move, driven rack 52 drives gear 53 to rotate, gear 53 drives driving rack 51 to move closer to wall 16. As a result, the two ends of connecting rope 81 move closer to each other, the taut connecting rope 81 becomes slack, and it loses its restriction. Under the action of second spring 73, connecting block 71 moves closer to hook 3, causing hook 3 to rotate away from movable lever 2, and hook 3 unfolds. Therefore, during the process of hook 3 moving away from wall 16, the end of hook 3 can be hooked on the inner wall of the center hole 171 of cap 17. Then, as hook 3 moves, hook 3 can drive cap 17 to move outward, thereby removing cap 17 from wall 16.

[0052] After removing the cap 17 from the wall 16, the cap 17 is hooked onto the hook 3. Hold the cap 17 and move the lever 54 away from the cap 17. This extends the movable rod 2 outwards, causing the hook 3 to move. At this point, the connecting rope 81 is slack. When the hook 3 passes through the cap 17, the connecting rope 81 becomes taut. With the movement of the lever 54, the taut rope 81, through the connecting block 71 and connecting rod 72, causes the hook 3 to rotate, retracting it. Next, slide the cap 17 outwards. During this sliding process, the inner wall of the cap 17 abuts against the ball bearing 112. Therefore, the guide plate 111 and the ball bearing 112 guide the sliding of the cap 17, preventing it from getting caught on the hook 3 again. This allows for quick and easy removal of the cap 17, completing the removal process.

[0053] The above are optional embodiments of this application and are not intended to limit the scope of protection of this application.
