Description

Technical Field

[0001] The present invention relates to the technical field of operating tools, and in particular to a sleeve which is convenient for disassembling a nut. Background Art

[0002] In industries such as automobile manufacturing, mechanical equipment manufacturing, and electronic equipment manufacturing, nuts and bolts are used in large quantities.

[0003] Conventional sockets, which frequently require workers to tighten nuts on production lines, can easily cause nuts to fall out, impacting production efficiency. In applications like automobile engine assembly, where numerous nuts must be precisely installed, sockets that prevent nut fallout can avoid wasted time and part damage, improving assembly quality and efficiency. Consequently, the manufacturing industry is in urgent need of such sockets.

[0004] Traditional sockets do not have an anti-drop function. When the socket removes the nut, the nut is likely to fall off the socket. When working in some dangerous environments (such as near high-voltage electrical equipment, around high-temperature equipment, etc.), the falling of the nut may lead to serious consequences. Summary of the Invention

[0005] In view of this, the present invention provides a sleeve for facilitating the removal of a nut, so as to solve the problem in the prior art that the sleeve for removing a nut has a low degree of fixing the nut after the nut is removed.

[0006] The present invention provides a sleeve for facilitating the disassembly of a nut, comprising: a disassembly piece, wherein the disassembly piece is provided with a first accommodating cavity, wherein the first accommodating cavity is provided with an opening, wherein the opening is used for placing the nut during disassembly;

[0007] a limit member disposed on an inner sidewall of the first accommodating cavity of the disassembly member on a side close to the opening, the limit member being movable in a radial direction of the disassembly member and having a protrusion extending toward a center position of the disassembly member; the limit member dividing the first accommodating cavity into a storage cavity and a disassembly cavity, the storage cavity being disposed on a side of the limit member facing away from the opening;

[0008] When in use, the nut of the disassembly piece is placed into the disassembly cavity at the opening position of the disassembly piece, and the protrusion abuts against the upper end surface of the nut to limit the nut. After the disassembly piece is screwed to disassemble the nut, the disassembly piece is moved toward the nut, and the nut squeezes the protrusion of the limiting piece, causing the limiting piece to move toward a center position away from the disassembly piece, so that the nut enters the storage cavity.

[0009] By setting a limiter, the accommodating chamber is divided into a storage chamber and a disassembly chamber, ensuring that the nut enters the storage chamber after disassembly, effectively preventing it from falling, and improving operational safety and efficiency.

[0010] In an optional embodiment, the disassembly piece is provided with a second accommodating cavity along the length direction of the disassembly piece, the limiting piece is slidably provided in the second accommodating cavity along the length direction of the disassembly piece, a through hole is provided between the second accommodating cavity and the first accommodating cavity, and at least part of the protrusion extends into the first accommodating cavity through the through hole.

[0011] By setting a second accommodating cavity, the limiting member is slidably set in the second accommodating cavity. When the limiting member slides, the protrusion slides out of the through hole. At this time, the limiting member releases the limit on the nut, and the nut can enter the storage cavity from the disassembly cavity.

[0012] In an optional embodiment, a switch component is provided on the disassembly component, the switch component is connected to the limiting component, and the switch component is used to control the movement of the limiting component along the length direction.

[0013] By providing a switch, the movement of the limit member can be limited and released more conveniently, simplifying the operation process.

[0014] In an optional embodiment, the switch member is arranged at an end of the disassembly member away from the opening, and an elastic member is provided between the limiting member and the disassembly member, and the elastic member has a force that drives the limiting member to move toward a side away from the opening.

[0015] The switch is arranged at one end of the disassembly part and the opening is located at the other end, which is convenient for one-handed operation. The limit part is easily reset by arranging an elastic part to ensure that the limit part automatically returns to its original position after each use.

[0016] In an optional embodiment, the limiting member includes: a horizontally arranged fixed plate and an extension rod, wherein a plurality of the extension rods are provided, the extension rods can be elastically deformed under the action of external force, the extension rods have the force to move toward the center position of the disassembly member, the protrusion is provided on the side of the extension rod facing the first accommodating cavity, and the extension rod is vertically provided on the fixed plate.

[0017] By arranging multiple extension rods on the fixing plate, it is ensured that the nut can be effectively limited at multiple angles, thereby enhancing the stability and adaptability of the structure.

[0018] In an optional embodiment, an insulating layer is provided between the switch element and the limiting element.

[0019] By providing an insulating layer between the switch member and the limiting member, the sleeve can be used to remove the live nut.

[0020] In an optional embodiment, the upper end surface of the insulating layer has a first clamping column extending toward the switch component, and the switch component has a first clamping groove plug-connected to the first clamping column.

[0021] By providing the first clamping column and the first clamping groove, the horizontal displacement of the insulating layer is limited by the first clamping column, so that a more stable clamping connection between the insulating layer and the switch element can be achieved.

[0022] In an optional embodiment, the lower end surface of the insulating layer has a second clamping column extending toward the limiting member, and the fixing plate has a second clamping groove connected to the second clamping column.

[0023] By providing the second clamping column and the second clamping groove, the horizontal displacement of the insulating layer is limited, so that a more stable clamping connection between the insulating layer and the limiting member can be achieved.

[0024] In an optional embodiment, the insulating layer is an annular resin.

[0025] After curing, epoxy resin has stable dielectric properties and high breakdown voltage, making it a relatively good insulating material.

[0026] In an optional embodiment, the cross-section of the first accommodating cavity of the disassembly member is hexagonal.

[0027] By setting the cross-section of the first accommodating cavity to be hexagonal, accurate positioning and disassembly of the hexagonal nut are facilitated, thereby improving the convenience and accuracy of operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0036] The following combination Figures 1 to 3 , describing embodiments of the present invention.

[0037] like Figure 1 、 Figure 2 、 Figure 3 As shown, according to an embodiment of the present invention, a sleeve for facilitating the disassembly of a nut is provided, comprising: a disassembly member 1, which is used to disassemble the nut. The disassembly member 1 is provided with a first accommodating chamber 2, which is provided with an opening, and the opening is used to place the nut during disassembly; a limiting member 3 is provided on the inner side wall of the first accommodating chamber 2 of the disassembly member 1 on a side close to the opening, and the limiting member 3 can move along the radial direction of the disassembly member 1, and the limiting member 3 has a protrusion 4 extending toward the center position of the disassembly member 1; the limiting member 3 divides the first accommodating chamber 2 into a storage chamber 5 and a disassembly chamber 6, wherein the storage chamber 5 is provided on the side of the limiting member 3 facing away from the opening, and the disassembly chamber 6 is provided on the side close to the opening.

[0038] When in use, the nut of the disassembly part 1 is placed in the disassembly cavity 6 at the opening position of the disassembly part 1, and the protrusion 4 abuts against the upper end surface of the nut to limit the nut. After the disassembly part 1 is screwed to disassemble the nut, the disassembly part 1 is moved toward the direction of the nut, and the nut squeezes the protrusion 4 of the limiting part 3, causing the limiting part 3 to move toward the center position away from the disassembly part 1, so that the nut enters the storage cavity 5.

[0039] That is to say, when using, it is necessary to place the nut on the opening position of the disassembly part 1, and then turn the knob. When turning, the limiter 3 abuts against the upper end of the nut to limit the movement of the nut in the length direction of the disassembly part 1. Then, the nut is unscrewed from the stud, and then the disassembly part 1 is squeezed toward the nut with force. The limiter 3 shrinks, allowing the nut to enter the storage chamber 5 of the disassembly part 1. Through the above technical solution, the disassembled nut can be placed in the storage chamber 5, and there is no need to worry about it falling after being unscrewed. By setting the limiter 3, the accommodating chamber is divided into the storage chamber 5 and the disassembly chamber 6, ensuring that the nut enters the storage chamber 5 after disassembly, effectively preventing it from falling, and improving operational safety and efficiency.

[0040] like Figure 2 、 Figure 4 As shown, in this embodiment, the disassembly member 1 is provided with a second accommodating chamber 7 along the length direction of the disassembly member 1, and the second accommodating chamber 7 is spaced apart from the first accommodating chamber 2. The limiting member 3 is slidably provided in the second accommodating chamber 7 along the length direction of the disassembly member 1, and a through hole 8 is provided between the second accommodating chamber 7 and the first accommodating chamber 2. At least a portion of the protrusion 4 extends into the first accommodating chamber 2 through the through hole 8, and the protrusion 4 is used to abut against the nut and limit the nut. During use, when the nut is in the disassembly chamber 6, the protrusion 4 extends out of the through hole 8 and abuts against the upper end face of the nut. At this time, when the disassembly member 1 rotates in a circle to disassemble the nut, the protrusion 4 limits the axial direction of the nut. When the nut needs to be moved from the disassembly chamber 6 to the storage chamber 5, the nut is in a state of being close to falling off on the stud. The disassembly member 1 is moved forcefully along the axial direction of the stud toward the nut. At this time, the nut will not be displaced due to the stud. At this time, the nut will squeeze the protrusion 4 of the limiting member 3 and move radially outward. When the convex point of the protrusion 4 is flush with the inner surface of the first accommodating chamber 2, the nut can enter the storage chamber 5 from the disassembly chamber 6. By setting a second accommodating chamber 7, the limiting member 3 is slidably set in the second accommodating chamber 7. When the limiting member 3 slides, the protrusion 4 slides out of the through hole 8. At this time, the limiting member 3 releases the limit on the nut, and the nut can enter the storage chamber 5 from the disassembly chamber 6. It should be noted that, as an alternative embodiment, the second accommodating chamber 7 may not be set, and the limiting member 3 may also be slidably set on the outer wall of the disassembly member 1.

[0041] Specifically, the protrusion 4 is hemispherical and has a radius of 1.5 mm. It should be noted that, as an alternative embodiment, the shape of the protrusion 4 may not be hemispherical, and the cross-section of the protrusion 4 may also be trapezoidal, with one end of the trapezoidal protrusion 4 connected to the stopper 3 and the other end extending toward the center of the disassembly component 1. The width of the side of the trapezoidal protrusion 4 facing the stopper 3 is greater than the width of the side of the trapezoidal protrusion 4 facing the center.

[0042] Specifically, the second accommodating chamber 7 is a circular ring-shaped chamber, which is arranged outside the first accommodating chamber 2 and has an inner diameter greater than an outer diameter of the first accommodating chamber 2 .

[0043] Specifically, three limiting members 3 are provided, and three through holes 8 are also provided, and the protrusions 4 of the limiting members 3 correspond to the through holes 8 one by one.

[0044] like Figure 2 As shown, in this embodiment, a switch member 9 is provided on the disassembly member 1, and the switch member 9 is connected to the limit member 3. The switch member 9 is used to control the movement of the limit member 3 along the length direction. By providing the switch member 9, the movement of the limit member 3 can be limited and released more conveniently, simplifying the operation process. It should be noted that, as an alternative embodiment, the switch member 9 may not be provided, and the upper end of the disassembly member 1 may be provided as an opening, that is, the end of the storage chamber 5 away from the disassembly chamber 6 may also be provided as an opening. When the disassembled nut needs to be released from the storage chamber 5, the disassembly member 1 may be inverted to allow the nut to fall from the storage chamber 5 by gravity.

[0045] like Figure 2 As shown, in this embodiment, a switch member 9 is positioned at the end of the disassembly member 1 away from the opening. An elastic member 10 is disposed between the stop member 3 and the disassembly member 1. The elastic member 10 is located on the side of the stop member 3 away from the switch member 9. In other words, the switch member 9 and the elastic member 10 are positioned on opposite sides of the stop member 3. The elastic member 10 exerts a force that forces the stop member 3 to move toward the side away from the opening. When the nut is in the disassembly chamber 6, no pressure is applied to the switch member 9. Once the nut has entered the storage chamber 5, and it is necessary to remove the nut from the disassembly member 1, the switch member 9 is pressed, causing the stop member 3 to move toward the opening. This compresses the elastic member 10, causing the hemispherical protrusion 4 to move radially outward, disengaging it from the through hole 8. All the nuts in the storage chamber 5 can now be removed from the disassembly member 1. After releasing the switch member 9, the stop member 3 automatically resets under the action of the elastic member 10, and the protrusion 4 re-enters the through hole 8, resuming its nut retaining function and ensuring safe and efficient operation. It should be noted that, as a replaceable embodiment, the switch member 9 can also be slidably set on the outer wall of the disassembly member 1 along the radial direction of the disassembly member 1, and one end of the switch member 9 is connected to the limit member 3. By pulling the switch member 9 outward, the protrusion 4 of the limit member 3 releases the limit on the nut.

[0046] The switch member 9 is arranged at one end of the disassembly member 1 and the opening is located at the other end, which is convenient for one-handed operation. The elastic member 10 is provided to conveniently reset the limit member 3 to ensure that the limit member 3 automatically returns to its original position after each use.

[0047] like Figure 2As shown, in this embodiment, the limiting member 3 includes: a horizontally arranged fixed plate and an extension rod, the fixed plate is arranged parallel to the switch member 9, and the switch member 9 is mounted on the fixed plate. There are multiple extension rods, and the extension rods are arranged on the outer edge of the fixed plate and extend toward the side of the opening. The fixed plate is circular. The extension rod can be elastically deformed under the action of external force, and the extension rod has the force to move toward the center position of the disassembly member 1. The protrusion 4 is arranged on the side of the extension rod facing the first accommodating cavity 2. At this time, the protrusion 4 extends from the through hole 8 into the first accommodating cavity 2. The extension rod is arranged vertically on the fixed plate. By arranging multiple extension rods on the fixed plate, it is ensured that the nut can be effectively limited at multiple angles, thereby enhancing the stability and adaptability of the structure. It should be noted that, as an alternative embodiment, the number of extension rods can be set to three at intervals. It should be noted that, as an alternative embodiment, the shape of the fixed plate can also be set to a regular hexagon.

[0048] like Figure 2 As shown, in this embodiment, an insulating layer 11 is provided between the switch member 9 and the stop member 3. The insulating layer 11 is made of epoxy resin. When used in a high-voltage electrical environment, such as a 380V electrical environment, the metal disassembly member 1 must be protected from contact with the human body and the risk of electric shock. By providing the insulating layer 11 between the switch member 9 and the stop member 3, the sleeve can be used to remove the live nut. It should be noted that, as an alternative embodiment, the insulating layer 11 can also be made of other materials, such as polyurethane foam.

[0049] like Figure 2 As shown, in this embodiment, the upper end surface of the insulating layer 11 has a first engaging post 12 extending toward the switch member 9, and the switch member 9 has a first engaging slot that plugs into the first engaging post 12. The lower end surface of the insulating layer 11 has a second engaging post 13 extending toward the stopper 3, and the fixing plate has a second engaging slot that plugs into the second engaging post 13. Both the first engaging post 12 and the second engaging post 13 are cylindrical. Multiple first engaging posts 12 and second engaging posts 13 are arranged in a circular array on the upper and lower end surfaces of the insulating layer 11, respectively, and multiple first and second engaging slots are also provided. The first and second engaging slots are also circular. By providing the first engaging post 12 and the first engaging slot, the first engaging post 12 limits the horizontal displacement of the insulating layer 11, achieving a more stable engagement between the insulating layer 11 and the switch member 9. By providing the second engaging post 13 and the second engaging slot, the horizontal displacement of the insulating layer 11 is limited, achieving a more stable engagement between the insulating layer 11 and the stopper 3. It should be noted that, as an alternative embodiment, the shapes of the first clamping post 12 and the second clamping post 13 may also be set to be square.

[0050] like Figure 2As shown, in this embodiment, the cross-section of the first accommodating cavity 2 of the disassembly component 1 is hexagonal. By setting the cross-section of the first accommodating cavity 2 to be hexagonal, the precise positioning and removal of the hexagonal nut is facilitated, improving the convenience and accuracy of the operation. The hexagonal cross-section design matches the shape of the nut, reducing sliding errors and improving grasping stability. It should be noted that as an alternative embodiment, the cross-section of the first accommodating cavity 2 of the disassembly component 1 can also be set to the shape of other nuts, such as: octagonal.

[0051] Specifically, the material of the disassembly part 1 is metal, and 45# steel can be selected. The fixing plate is thin steel, and the extension rod is made of 65Mn spring steel. The surface is quenched and the hardness is HRC45-50, ensuring its elasticity and durability. The disassembly part 1 is a cylinder with an opening at one end and a switch part 9 at the other end. The switch part 9 is slidably arranged on the disassembly part 1 along the length direction of the disassembly part 1. An elastic part 10 is provided between the limit part 3 and the disassembly part 1. The elastic part 10 is located on the side of the limit part 3 away from the switch part 9. The elastic part 10 is a spring. Due to the elastic force of the spring, the limit part 3 can be quickly reset after the limit is released.

[0052] The present invention relates to a sleeve for facilitating the removal of nuts, and the installation process is as follows: first, install the elastic member 10 on the side of the limit member 3 away from the switch member 9, ensure that one end of the elastic member 10 is fixed on the disassembly member 1, and the other end is in contact with the limit member 3, providing the necessary thrust for the limit member 3. Next, accurately install the limit member 3 into the second accommodating cavity 7 of the disassembly member 1, ensuring that it can slide smoothly along the length direction of the disassembly member 1. Then, install the switch member 9 at the end of the disassembly member 1 away from the opening, and ensure that it is connected to the limit member 3, so as to effectively control the movement of the limit member 3. During the installation process, it is necessary to ensure that the protrusion 4 can accurately pass through the through hole 8 and extend into the first accommodating cavity 2, so as to effectively limit the nut. In addition, it is necessary to confirm that the cross-section of the first accommodating cavity 2 of the disassembly member 1 matches the shape of the nut to be removed.

[0053] Working principle of the socket for easy removal of nuts: Figure 2 As shown, during use, the nut to be removed is first placed into the opening of the removal member 1, within the removal cavity 6. At this point, the protrusion 4 of the retaining member 3 extends out of the through-hole 8 and abuts against the upper end face of the nut, limiting the nut's axial position. Subsequently, the removal member 1 is rotated, utilizing the friction between the member and the nut to unscrew the nut from the stud.

[0054] When the nut is successfully removed, use force to move the removal piece 1 along the axial direction of the stud toward the nut. Due to the restriction of the stud, the nut will not move, but will squeeze the protrusion 4 of the limiter 3. After being squeezed, the protrusion 4 will move radially outward, causing the limiter 3 to shrink. When the convex point of the protrusion 4 is flush with the inner surface of the first accommodating chamber 2, the nut can smoothly enter the storage chamber 5 from the removal chamber 6 (as shown in the figure). Figure 3 shown).

[0055] The setting of the storage chamber 5 allows the removed nuts to be collected in the storage chamber 5, avoiding the problem of nuts falling. At the same time, by setting the limiter 3 and the through hole 8, it is ensured that the nuts can be effectively limited during the disassembly process. The switch member 9 is connected to the limiter 3 and is used to control the movement of the limiter 3. The elastic member 10 and the switch member 9 are respectively located on both sides of the fixed plate of the limiter 3, wherein the elastic member 10 is located on the side facing the opening, and the two ends of the elastic member 10 are respectively connected to the fixed plate and the disassembly member 1, and the elastic member 10 has a force to drive the limiter 3 to move toward the side away from the opening. When the nuts in the storage chamber 5 need to be cleaned, it is only necessary to press the switch member 9 to move the limiter 3 toward the side of the opening. At this time, the elastic member 10 is compressed by force, and the protrusion 4 comes out of the through hole 8, releasing the limit on the nut. Subsequently, the nut in the storage chamber 5 can be detached from the disassembly member 1. After the switch member 9 is released, the limiting member 3 is automatically reset under the action of the elastic member 10, and the protrusion 4 re-extends into the through hole 8, thereby restoring the limiting function of the nut.

[0056] Although the embodiments of the present invention have been described with reference to the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention. Such modifications and variations are all within the scope defined by the appended claims.
