A sleeve with anti-slip function

Abstract

This invention discloses a sleeve with anti-slip function, relating to the field of sleeves. It includes a sleeve assembly with a coating and clamping mechanism at its top. The coating and clamping mechanism includes a mounting box, the bottom of which is fixedly connected to the top of the sleeve body. The coating and clamping mechanism is used to clamp the required screw and adjust the clamping distance according to the screw size. During the adjustment of the clamping distance, the coating and clamping mechanism controls the outflow of lubricating oil stored in the oil reservoir. During screw rotation, it applies lubricating oil to the mounting surface of the screw and the screw fixing point. A cam synchronously pushes a hollow shaft downwards during rotation, causing the lubricating oil inside the oil reservoir to be discharged through the outer surface of the hollow shaft, the oil guide hole at the bottom, and the gap between the hollow shaft and the oil guide tube. This reduces the frictional resistance between the screw and the screw fixing point, improves the smoothness of disassembling rusty screws, and thus increases the disassembly speed of rusty screws.

Description

Technical Field

[0001] This invention relates to the field of sleeve technology, specifically to a sleeve with anti-slip function. Background Technology

[0002] A socket is short for a socket wrench. Because it is fitted over various wrenches and is shaped like a cylinder, it is commonly known as a socket. It is a commonly used tool in production, maintenance, and daily life. According to the driving device, it can be divided into pneumatic sockets (also known as wind-driven sockets), manual sockets, and electric sockets.

[0003] However, existing sleeves still have the following drawbacks after use:

[0004] 1. Sockets often encounter screws of different specifications during use. Since the range of the socket on the screw is fixed, it is necessary to frequently change the socket when encountering screws of different specifications. This results in excessive time spent on tightening or loosening the screws, which is inconvenient for users.

[0005] 2. During the disassembly of screws, the screws are easily rusted due to prolonged exposure to the external environment, which increases the difficulty of disassembly. Therefore, during the disassembly process, it is necessary to remove the socket from the screw, apply lubricant to the mounting surface of the screw and the screw fixing point, and then put the socket back on the screw. This operation is cumbersome and increases the disassembly time of rusted screws, making it inconvenient for users. Summary of the Invention

[0006] (a) Technical problems to be solved

[0007] To address the aforementioned shortcomings of existing technologies, this invention provides a sleeve with anti-slip function, which effectively solves the problem that in existing technologies, when disassembling rusty screws, the sleeve needs to be removed again to apply lubricant, and then the sleeve needs to be put back on the screw after application, which causes inconvenience to the user.

[0011] The coating clamping mechanism includes a mounting box, the bottom of which is fixedly connected to the top of the sleeve body. The coating clamping mechanism is used to clamp the screws to be used and adjust the clamping distance according to the size of the screws. During the adjustment of the clamping distance, the coating clamping mechanism controls the output of the lubricating oil stored in the oil storage chamber and applies the lubricating oil to the mounting surface of the screw and the screw fixing point during the rotation of the screw.

[0013] Furthermore, the mounting cylinder has a gear inside, and a cam is fixedly connected to one end of the rotating shaft near the gear. An integral central shaft is provided at one end of the gear near the rotating shaft, and this central shaft is fixedly connected to the back of the cam and rotatably connected to the inner wall of the mounting cylinder. The integral central shaft of the gear is rotatably connected to the inner wall of the sleeve body. A geared disc is rotatably connected to the inner wall of the mounting cylinder, and the gear and the geared disc mesh with each other. A drive rail is fixedly connected to the bottom end of the geared disc, and a drive block is slidably connected to the outer surface of the drive rail. The drive block is slidably connected to the inner wall of the mounting cylinder. Multiple clamping plates are provided inside the sleeve body, and the top end of each clamping plate is fixedly connected to the top end of the drive block.

[0014] Furthermore, the outer surface of the clamping plate is fixedly connected with multiple conical protrusions, the bottom end of the clamping plate near the mounting box is fixedly connected with a connecting plate, the bottom end of the connecting plate is fixedly connected with an oil-absorbing sponge block, and the outer surface of the oil-absorbing sponge block is provided with an integrated placement box, which is fixedly connected to the bottom end of the sleeve body.

[0015] Furthermore, the mounting box contains a hollow rod that is slidably connected to the top of the sleeve body and passes through the inner wall of the oil storage chamber. A drive rod is slidably connected inside the hollow rod and passes through the inner wall of the oil storage chamber. A positioning sleeve is provided on the outer surface of the hollow rod, and an integral positioning post is provided on the back of the positioning sleeve and is threaded to the outer surface of the hollow rod.

[0018] Furthermore, a second spring is fixedly connected to the top end of the sealing tube near the hollow shaft, and the top end of the second spring is fixedly connected to the bottom end of the oil guide tube.

[0019] (III) Beneficial Effects

[0020] Compared with the known prior art, the technical solution provided by this invention has the following beneficial effects:

[0021] 1. The device is equipped with a cam, hollow shaft, sealing tube, and clamping plates. The rotation of the cam synchronously drives the clamping plates to move in opposite directions, thereby adjusting the clamping distance between the clamping plates according to different screw specifications. During the rotation of the cam, the hollow shaft is pushed downward, which in turn pushes the sealing tube to open. This allows the lubricating oil inside the oil reservoir to be discharged through the oil guide hole on the outer surface of the hollow shaft, the bottom end, and the gap between the hollow shaft and the oil guide tube. This lubricating oil is applied to the mounting surface of the screw and the screw fixing point, improving the lubrication of the screw and the screw fixing point, thereby reducing the difficulty of disassembling rusty screws, speeding up the removal of rusty screws, saving disassembly time, and facilitating user operation.

[0022] 2. By incorporating an oil-absorbing sponge block, the material of the sponge guides the drained lubricant to the screw fixing point. The movement of the clamping plate simultaneously stretches the oil-absorbing sponge block, allowing the distance between the sponge block and the screw to be adjusted according to different screw sizes during clamping. During screw removal, the sponge block rotates, applying lubricant to the periphery of the screw and its fixing surface. This expands the lubricant application area, accelerates lubricant contact with the screw, reduces frictional resistance between the screw and its fixing point, improves the smoothness of removing rusty screws, and ultimately increases the speed of disassembly.

[0023] 3. By adding a positioning sleeve, the rotation of the positioning sleeve controls the sliding of the drive rod inside the hollow rod, thereby controlling the outflow of lubricating oil from the oil reservoir. This allows users to selectively apply lubricating oil when disassembling rusty screws to reduce frictional resistance between the screws and the screw fixing points. Furthermore, during the tightening of screws, the lubricating oil is prevented from flowing out of the oil reservoir, thus avoiding lubricating oil leakage when no lubricating oil is needed, reducing lubricating oil consumption, saving lubricating oil usage costs, and facilitating user operation.

[0024] 4. By adding a limiting block, the rotation of the shaft is restricted, thereby preventing the shaft from rotating under different external forces. This prevents the clamping plate from moving due to the shaft's rotation, thus avoiding any impact on the screw clamping. This improves the screw's tightness during disassembly or tightening and facilitates user operation. Attached Figure Description

Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0039] The present invention will be further described below with reference to embodiments.

[0040] This embodiment provides a sleeve with anti-slip function, such as... Figures 1 to 9 As shown, the device includes a sleeve assembly 100, which includes a sleeve body 101. An oil storage chamber 103 is formed inside the sleeve body 101, and the oil storage chamber 103 is connected to an oil inlet pipe 102.

[0041] In view of the above-mentioned sleeve assembly 100, it can be specifically implemented as follows:

[0042] The top of the sleeve assembly 100 is provided with a coating clamping mechanism 200. The coating clamping mechanism 200 includes a mounting box 201. The bottom end of the mounting box 201 is fixedly connected to the top of the sleeve body 101. The coating clamping mechanism 200 is used to clamp the screw to be used and adjust the clamping distance according to the size of the screw. During the adjustment of the clamping distance, the coating clamping mechanism 200 controls the output of the lubricating oil stored in the oil reservoir 103 and applies the lubricating oil to the mounting surface of the screw and the screw fixing point during the rotation of the screw.

[0043] As a preferred embodiment of this example, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 7 and Figure 8As shown, a gear 207 is installed inside the mounting cylinder 202. A cam 206 is fixedly connected to one end of the rotating shaft 204 near the gear 207. An integral central shaft is installed at one end of the gear 207 near the rotating shaft 204, and this central shaft is fixedly connected to the back of the cam 206 and rotatably connected to the inner wall of the mounting cylinder 202. The integral central shaft of the gear 207 is rotatably connected to the inner wall of the sleeve body 101. A gear disk 208 is rotatably connected to the inner wall of the mounting cylinder 202. The gear 207 and the gear disk 208 mesh with each other. A drive rail 209 is fixedly connected to the bottom end of the gear disk 208. A drive block 210 is slidably connected to the outer surface of the drive rail 209 and is slidably connected to the inner wall of the mounting cylinder 202. Multiple clamping plates 222 are installed inside the sleeve body 101. The top end of the clamping plates 222 is fixedly connected to the top end of the drive block 210. A hollow rod is installed inside the mounting box 201. 213, hollow rod 213 is slidably connected to the top end of sleeve body 101 and passes through the inner wall of oil storage cavity 103. Drive rod 215 is slidably connected inside hollow rod 213 and passes through the inner wall of oil storage cavity 103. Positioning sleeve 214 is provided on the outer surface of hollow rod 213. An integral positioning post is provided on the back of positioning sleeve 214 and the positioning post is threaded to the outer surface of hollow rod 213. The integral positioning post of positioning sleeve 214 is threaded to the outer surface of drive rod 215. Connecting rod 217 is fixedly connected to the bottom end of drive rod 215. Hollow shaft 218 is fixedly connected to the bottom end of connecting rod 217. Multiple oil guide holes are opened on the outer surface and bottom end of hollow shaft 218. Oil storage cavity 103 is connected to oil guide pipe 219. A part of hollow shaft 218 is located inside oil guide pipe 219. Multiple sealing tube pieces 220 are hinged to the bottom end of oil guide pipe 219 away from hollow shaft 218. The opposing movement of the clamping plate 222 synchronously guides the lubricating oil to the outer surface of the oil-absorbing sponge block 212, and applies lubricating oil when disassembling rusty screws, thereby improving the smoothness of disassembling rusty screws. The single sleeve body 101 enables the disassembly or tightening of screws of different specifications.

[0044] As a preferred embodiment of this example, Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, the coating clamping mechanism 200 includes a rotating handle 203. A mounting cylinder 202 is fixedly connected to the top end of the sleeve body 101. A rotating shaft 204 is fixedly connected to one end of the rotating handle 203 near the mounting box 201. The rotating shaft 204 is rotatably connected to the mounting box 201. A limiting block 205 is threadedly connected to the outer surface of the rotating shaft 204. An integral limiting sleeve is provided on the side of the limiting block 205 near the mounting box 201, and this limiting sleeve is threadedly connected to the side of the mounting box 201 away from the mounting cylinder 202 and to the outer surface of the rotating shaft 204. The rotation of the limiting block 205 restricts the rotation of the rotating shaft 204, thereby preventing the rotating shaft 204 from rotating under different external forces, and thus avoiding any impact on the clamping of the screw.

[0045] In this embodiment, as Figure 4 As shown, a plurality of conical protrusions 223 are fixedly connected to the outer surface of the clamping plate 222. A connecting plate 211 is fixedly connected to the bottom end of the clamping plate 222 near the mounting box 201. An oil-absorbing sponge block 212 is fixedly connected to the bottom end of the connecting plate 211. An integrated placement box is provided on the outer surface of the oil-absorbing sponge block 212 and the placement box is fixedly connected to the bottom end of the sleeve body 101.

[0046] In this embodiment, as Figure 3 As shown, springs 216 are symmetrically fixedly connected to the inner wall of the oil storage chamber 103, and the bottom end of springs 216 is fixedly connected to the outer surface of the drive rod 215.

[0047] In this embodiment, as Figure 9 As shown, a spring 221 is fixedly connected to the top end of the sealing tube 220 near the hollow shaft 218, and the top end of the spring 221 is fixedly connected to the bottom end of the oil guide tube 219.

[0048] Compared with the prior art, users can tighten or loosen screws of different specifications by adjusting the clamping distance between the clamping plates 222 when using the sleeve body 101. When loosening rusty screws, users can selectively apply lubricating oil to reduce the frictional resistance between the screws and the screw fixing points, thereby speeding up the loosening of rusty screws, improving the smoothness of loosening rusty screws, and making it easier for users to operate.

[0049] Working principle:

[0050] Initial limitations: Before the invention is used, the limiting block 205 does not restrict the rotation state of the rotating shaft 204, the positioning sleeve 214 does not restrict the sliding state of the drive rod 215 inside the hollow rod 213, the lubricating oil inside the oil storage chamber 103 is full, the sealing tube 220 is in a sealing state of the bottom end of the oil guide tube 219, the oil-absorbing sponge block 212 is in a state of not absorbing lubricating oil, and a portion of the lubricating oil inside the oil storage chamber 103 has entered the interior of the hollow shaft 218 through its own oil guide hole. At this time, the oil guide tube 219 is located directly above the oil-absorbing sponge block 212.

[0051] Steps for tightening screws:

[0052] First, the user places the socket body 101 onto the screw to be removed, with the exposed portion of the screw positioned between multiple clamps 222. Then, the user rotates the rotating handle 203 clockwise. During this clockwise rotation, the rotating handle 203 simultaneously drives the clockwise rotating shaft 204 to rotate. The rotating shaft 204, in turn, drives the cam 206 clockwise. The cam 206, in turn, drives the integrated central shaft of the gear 207 clockwise, thus causing the gear 207 to rotate clockwise. Since the gear 207 meshes with the gear disc 208, the clockwise rotation of the gear 207 simultaneously drives the gear disc 208 to rotate clockwise. During the rotation, the drive rail 209 is rotated synchronously. Since the drive block 210 is slidably connected to the drive rail 209 and the mounting cylinder 202, multiple drive blocks 210 are moved closer together during the clockwise rotation of the drive rail 209. During the movement of the drive blocks 210, the clamping plates 222 at the bottom of the drive blocks 210 are moved closer together. The clamping plates 222 move the conical protrusions 223 closer together, clamping the screws located between the clamping plates 222. The clamping distance between the clamping plates 222 can be adjusted according to the screws of different specifications, so that the user can disassemble or tighten screws of different specifications through a single sleeve body 101, improving the practicality of the sleeve body 101 and making it easier for the user to operate.

[0053] As the clamping plates 222 move closer together, they simultaneously drive the connecting plates 211 at the bottom of the clamping plates 222 to move closer together. As the connecting plates 211 move closer together, they pull the oil-absorbing sponge block 212 to move, so that the end of the oil-absorbing sponge block 212 near the clamping plates 222 gradually moves closer to the screw. Thus, while disassembling screws of different specifications, the oil-absorbing sponge block 212 is moved closer together, so that the oil-absorbing sponge block 212 is always in contact with the screw.

[0054] After clamping plate 222 clamps the screw, the user rotates the limiting block 205 clockwise. Since the limiting block 205 is threaded onto the outer surface of the rotating shaft 204, and the integrated limiting sleeve of the limiting block 205 is threaded onto the side of the mounting box 201 away from the mounting cylinder 202 and the outer surface of the rotating shaft 204, the limiting block 205 moves along the outer surface of the rotating shaft 204 during rotation. This causes the integrated limiting sleeve of the limiting block 205 to gradually move towards the side of the mounting box 201 away from the mounting cylinder 202, until the limiting sleeve... The integrated limiting sleeve 205 moves completely to the side of the mounting box 201 away from the mounting cylinder 202 by means of the thread, thereby stopping the rotation of the limiting block 205, thereby limiting the rotation state of the rotating shaft 204 by the limiting block 205, thereby limiting the state of the clamping plates 222 close to each other. After disassembling or tightening the screw, the user can reverse the rotation steps of the rotating handle 203 and the limiting block 205, the principle of which is the same as above, thereby moving the clamping plates 222 away from the screw and removing the sleeve body 101 from the screw.

[0055] Steps for applying lubricant:

[0056] When it is necessary to disassemble rusty screws or reduce the frictional resistance between screws and screw fixing points, the user can rotate the positioning sleeve 214 clockwise. Since the positioning sleeve 214 is threadedly connected to the outer surface of the hollow rod 213 and the outer surface of the drive rod 215, when the positioning sleeve 214 rotates, its integrated positioning post moves towards the drive rod 215 by means of the thread, thereby causing part of the integrated positioning post of the positioning sleeve 214 to move to the outer surface of the drive rod 215, thereby positioning the drive rod 215 inside the hollow rod 213.

[0057] During its rotation, cam 206 pushes the top of hollow rod 213 downward. The rotation principle of cam 206 is the same as described above. During its downward movement, hollow rod 213 synchronously drives drive rod 215 downward. Drive rod 215 stretches spring 216 during its downward movement, causing spring 216 to deform. Simultaneously, drive rod 215 drives connecting rod 217 at its bottom downward. Connecting rod 217 synchronously drives hollow shaft 218 downward. Due to the oil guide pipe 219... Multiple sealing tubes 220 are hinged to the bottom end away from the hollow shaft 218. A portion of the hollow shaft 218 is located inside the oil guide pipe 219. Therefore, during the downward movement of the hollow shaft 218, it pushes the multiple sealing tubes 220, causing the top ends of the sealing tubes 220 to be compressed, thereby causing the multiple sealing tubes 220 to flip. This, in turn, causes the multiple sealing tubes 220 to open as the hollow shaft 218 moves downward. During the opening process, the sealing tubes 220 stretch the second spring 221, causing the second spring 221 to deform during the stretching process. Due to the storage... The inner wall of the oil cavity 103 is connected to an oil guide pipe 219. Therefore, as the sealing tubes 220 move away from each other, the lubricating oil inside the oil storage cavity 103 is guided through the gap between the outer surface of the hollow shaft 218 and the inner wall of the oil guide pipe 219, as well as through the oil guide hole of the hollow shaft 218 itself, from the oil guide pipe 219 to the top of the oil-absorbing sponge block 212. The water absorption of the oil-absorbing sponge block 212 fills the entire oil-absorbing sponge block 212, thereby applying lubricating oil around the screw, thus reducing the frictional resistance between the screw and the screw fixing point. The user can then... The top of the mounting cylinder 202 is equipped with a drive source, which drives the oil-absorbing sponge block 212 to rotate synchronously during the screw removal process, thereby expanding the coating area of ​​the oil-absorbing sponge block 212. Since screws are easily corroded by water and acidic gases during long-term use, by applying lubricating oil to the surface of the rusty screw, the lubricating oil flows from the gap between the rusty screw and the screw fixing point to the friction surface of the rusty screw. The lubricating oil forms an oil film on the friction surface of the rusty screw, reducing the frictional resistance between the rusty screw and the screw fixing point, thereby speeding up the removal of the rusty screw.

[0058] When the cam 206 moves away from the top of the hollow rod 213, the hollow rod 213 loses the thrust from the cam 206. The transmission principle between the hollow rod 213 and the drive rod 215 is the same as described above. This causes the spring 216 to lose the tension from the drive rod 215, allowing the drive rod 215 to move automatically downwards due to the deformation of the spring 216. During the upward movement of the drive rod 215, the hollow shaft 218 is simultaneously driven upwards. The transmission principle between the drive rod 215 and the hollow shaft 218 is the same as described above. During the upward movement of the hollow shaft 218, the sealing tube 220 loses the thrust from the hollow shaft 218, thus causing the spring 221 to lose the tension from the sealing tube 220. This causes the sealing tube 220 to automatically reset due to the deformation of the spring 221, blocking the oil guide pipe 219 and preventing the lubricating oil from being discharged, reducing the consumption of lubricating oil and facilitating user operation.

[0059] When the user does not need to use lubricating oil, the positioning sleeve 214 is rotated in the opposite direction. The movement principle of the positioning sleeve 214 is the same as described above, which allows the drive rod 215 to slide inside the hollow rod 213. This prevents the hollow rod 213 from synchronously driving the drive rod 215 downward during its downward movement, thus allowing the lubricating oil to be discharged from the oil storage chamber 103 when it is not needed, reducing the consumption of lubricating oil.

[0060] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
