Abstract
Description
Technical Field
[0001] This utility model relates to the field of operating tools, specifically to a sleeve that facilitates the disassembly of nuts. Background Technology
[0002] Nuts and bolts are used extensively in industries such as automobile manufacturing, machinery and equipment manufacturing, and electronic equipment manufacturing.
[0003] In existing technologies, workers on production lines need to frequently tighten nuts, and traditional sockets are prone to causing nuts to fall off, affecting production rhythm and efficiency. In applications like automotive engine assembly, numerous nuts need to be installed precisely. Sockets that prevent nuts from falling off can avoid wasted time and damage to parts caused by falling nuts, improving assembly quality and efficiency. Therefore, the manufacturing industry has an urgent need for such sockets.
[0004] Traditional sockets do not have a drop-proof function. When the nut is removed from the socket, it is easy for the nut to fall off the socket. In some dangerous environments (such as near high-voltage electrical equipment, or around high-temperature equipment), the falling nut may have serious consequences. Utility Model Content
[0005] In view of this, the present invention provides a sleeve for easy disassembly of nuts, so as to solve the problem that the sleeve for disassembling nuts in the prior art has a low degree of firmness in fixing the nuts after disassembly.
[0006] This utility model provides a sleeve for easy disassembly of nuts, comprising: a disassembly component, wherein the disassembly component is provided with a first receiving cavity, the first receiving cavity is provided with an opening, the opening being used to place the nut during disassembly;
[0007] A limiting member is disposed on the inner sidewall of the first receiving cavity of the disassembly member near the opening. The limiting member is movable in the radial direction of the disassembly member and has a protrusion extending toward the center of the disassembly member. The limiting member divides the first receiving cavity into a storage cavity and a disassembly cavity, and the storage cavity is disposed on the side of the limiting member away from the opening.
[0008] In use, the nut of the disassembly piece is placed into the disassembly cavity at the opening of the disassembly piece. The protrusion abuts against the upper end of the nut to limit the nut. After the nut is disassembled by turning the disassembly piece, the disassembly piece is moved toward the nut. The nut presses against the protrusion of the limiting piece, causing the limiting piece to move away from the center of the disassembly piece, so that the nut enters the storage cavity.
[0009] By setting a limiting component, the receiving cavity is divided into a storage cavity and a disassembly cavity, ensuring that the nut enters the storage cavity after disassembly, effectively preventing it from falling out and improving operational safety and efficiency.
[0010] In one optional embodiment, the disassembly member is provided with a second receiving cavity along the length direction of the disassembly member, the limiting member is slidably disposed in the second receiving cavity along the length direction of the disassembly member, a through hole is provided between the second receiving cavity and the first receiving cavity, and at least a portion of the protrusion extends into the first receiving cavity through the through hole.
[0011] By setting a second receiving cavity, the limiting member is slidably disposed in the second receiving cavity. When the limiting member slides, the protrusion slides out from the through hole. At this time, the limiting member releases the limiting of the nut, and the nut can enter the storage cavity from the disassembly cavity.
[0012] In one optional embodiment, the disassembly component is provided with a switch component, which is connected to the limiting component and is used to control the movement of the limiting component along the length direction.
[0013] By setting up a switch, the movement of the limit component can be more easily limited and released, simplifying the operation process.
[0014] In one alternative embodiment, the switching element is disposed at the end of the disassembly member away from the opening, and an elastic element is disposed between the limiting element and the disassembly member, the elastic element having a force that drives the limiting element to move toward the side away from the opening.
[0015] The switch is located at one end of the disassembly part, and the opening is located at the other end, which facilitates one-handed operation. The elastic element is set to easily reset the limit element, ensuring that the limit element automatically returns to its original position after each use.
[0016] In one optional embodiment, the limiting member includes: a horizontally arranged fixed plate and an extension rod, wherein multiple extension rods are provided, the extension rods are elastically deformable under the action of external force, the extension rods have a force that moves toward the center position of the disassembly member, the protrusion is provided on the side of the extension rod facing the first receiving cavity, and the extension rods are vertically arranged on the fixed plate.
[0017] By setting multiple extension rods on the fixed plate, the nut can be effectively limited at multiple angles, enhancing the stability and adaptability of the structure.
[0018] In one alternative embodiment, an insulating layer is provided between the switching element and the limiting element.
[0019] By placing an insulating layer between the switch and the limit switch, the bushing can be used to disassemble the live nut.
[0020] In one alternative embodiment, the upper end face of the insulating layer has a first snap-fit post extending toward the switch member, and the switch member has a first snap-fit groove that is inserted into the first snap-fit post.
[0021] By setting a first snap-fit post and a first snap-fit slot, the horizontal displacement of the insulation layer can be limited by the first snap-fit post, thus achieving a more stable snap-fit between the insulation layer and the switching component.
[0022] In one alternative embodiment, the lower end face of the insulating layer has a second snap-fit post extending toward the limiting member, and the limiting member has a second snap-fit groove that is inserted and connected to the second snap-fit post.
[0023] By setting a second snap-fit post and a second snap-fit groove, the horizontal displacement of the insulation layer is limited, which can achieve a more stable snap-fit between the insulation layer and the limiting component.
[0024] In one alternative embodiment, the insulating layer is epoxy resin.
[0025] After curing, epoxy resin has stable dielectric properties and high breakdown voltage, making it a relatively good insulating material.
[0026] In one alternative embodiment, the first receiving cavity of the disassembly component has a hexagonal cross-section.
[0027] By setting the cross-section of the first receiving cavity to be hexagonal, it is convenient to accurately position and disassemble the hexagonal nut, thereby improving the convenience and accuracy of operation. Attached Figure Description

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0036] The following is combined with Figures 1 to 3 The following describes 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 nut disassembly is provided, comprising: a disassembly member 1, used for disassembling the nut. The disassembly member 1 is provided with a first receiving cavity 2, the first receiving cavity 2 having an opening for placing the nut during disassembly; a limiting member 3 is disposed on the inner sidewall of the first receiving cavity 2 of the disassembly member 1 near the opening, the limiting member 3 is movable in the radial direction of the disassembly member 1, and the limiting member 3 has a protrusion 4 extending toward the center of the disassembly member 1; the limiting member 3 divides the first receiving cavity 2 into a storage cavity 5 and a disassembly cavity 6, wherein the storage cavity 5 is disposed on the side of the limiting member 3 away from the opening, and the disassembly cavity 6 is disposed on the side near the opening.
[0038] When in use, place the nut of the disassembly piece 1 into the disassembly cavity 6 at the opening of the disassembly piece 1. The protrusion 4 abuts against the upper end of the nut to limit the nut. After the nut is disassembled by turning the disassembly piece 1, move the disassembly piece 1 toward the nut. The nut squeezes the protrusion 4 of the limiting piece 3, causing the limiting piece 3 to move toward a position away from the center of the disassembly piece 1, so that the nut enters the storage cavity 5.
[0039] In other words, during use, the nut needs to be placed in the opening position of the disassembly part 1, and then the knob is turned. During turning, the limiting part 3 abuts against the upper end of the nut to limit its movement along the length of the disassembly part 1. Then, the nut is unscrewed from the stud, and the disassembly part 1 is pressed towards the nut. The limiting part 3 contracts, allowing the nut to enter the storage cavity 5 of the disassembly part 1. This technical solution ensures that the disassembled nut is placed in the storage cavity 5, eliminating concerns about it falling out after being unscrewed. By setting the limiting part 3 to divide the receiving cavity into the storage cavity 5 and the disassembly cavity 6, it ensures that the nut enters the storage cavity 5 after disassembly, effectively preventing it from falling out and improving operational safety and efficiency.
[0040] like Figure 2 , Figure 4 As shown, in this embodiment, the disassembly member 1 has a second receiving cavity 7 along its length, and the second receiving cavity 7 is spaced apart from the first receiving cavity 2. The limiting member 3 is slidably disposed in the second receiving cavity 7 along the length of the disassembly member 1. A through hole 8 is provided between the second receiving cavity 7 and the first receiving cavity 2. At least a portion of the protrusion 4 extends into the first receiving cavity 2 through the through hole 8. The protrusion 4 is used to abut against the nut and limit the nut. In use, when the nut is in the disassembly cavity 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 circumferentially to disassemble the nut, the protrusion 4 limits the axial direction of the nut. When the nut needs to be moved from the disassembly cavity 6 to the storage cavity 5, the nut is in a near-falling state on the stud. The disassembly component 1 is moved axially toward the nut along the stud. Because of the stud, the nut will not shift. The nut will then press the protrusion 4 of the limiting component 3 and move radially outward. When the protrusion 4 is flush with the inner surface of the first receiving cavity 2, the nut can move from the disassembly cavity 6 into the storage cavity 5. By providing a second receiving cavity 7, the limiting component 3 is slidably disposed within it. When the limiting component 3 slides, the protrusion 4 slides out of the through hole 8, releasing the limiting component 3 from the nut, allowing the nut to move from the disassembly cavity 6 into the storage cavity 5. It should be noted that, as an alternative implementation, the second receiving cavity 7 may not be provided, and the limiting component 3 may also be slidably disposed on the outer wall of the disassembly component 1.
[0041] Specifically, the protrusion 4 is a hemispherical protrusion 4 with a radius of 1.5mm. It should be noted that, as an alternative implementation, the shape of the protrusion 4 may not be hemispherical; its cross-section may also be trapezoidal. One end of the trapezoidal protrusion 4 is connected to the limiting member 3, and the other end extends toward the center of the disassembly member 1. The width of the side of the trapezoidal protrusion 4 facing the limiting member 3 is greater than the width of the side of the trapezoidal protrusion 4 facing the center.
[0042] Specifically, the second receiving cavity 7 is an annular cavity, located outside the first receiving cavity 2, and its inner diameter is larger than the outer diameter of the first receiving cavity 2.
[0043] Specifically, there are three limiting members 3 and three through holes 8, with the protrusions 4 of the limiting members 3 corresponding one-to-one with the through holes 8.
[0044] like Figure 2 As shown, in this embodiment, the disassembly component 1 is equipped with a switch component 9, which is connected to the limiting component 3. The switch component 9 is used to control the movement of the limiting component 3 along its length. By providing the switch component 9, it is easier to limit and release the movement of the limiting component 3, simplifying the operation process. It should be noted that, as an alternative implementation, the switch component 9 can be omitted, and the upper end of the disassembly component 1 can be made open, that is, the end of the storage cavity 5 away from the disassembly cavity 6 can also be made open. When it is necessary to release the disassembled nut from the storage cavity 5, the disassembly component 1 can be inverted, and the nut can be dropped from the storage cavity 5 by gravity.
[0045] like Figure 2 As shown, in this embodiment, the switch 9 is located at the end of the disassembly member 1 away from the opening. An elastic element 10 is provided between the limiting member 3 and the disassembly member 1. The elastic element 10 is located on the side of the limiting member 3 away from the switch 9; that is, the switch 9 and the elastic element 10 are positioned opposite each other on both sides of the limiting member 3. The elastic element 10 has a force that drives the limiting member 3 to move towards the side away from the opening. When the nut is in the disassembly cavity 6, the switch 9 is not pressed. When the nut enters the storage cavity 5, and it is necessary to remove the nut from the disassembly member 1, the switch 9 is pressed, causing the limiting member 3 to move towards the opening. At this time, the elastic element 10 is compressed, and the hemispherical protrusion 4 moves radially outward, causing the protrusion 4 to disengage from the through hole 8. At this time, all the nuts in the storage cavity 5 can be removed from the disassembly member 1. After releasing the switch 9, under the action of the elastic element 10, the limiting member 3 automatically resets, and the protrusion 4 re-enters the through hole 8, restoring the limiting function for the nut and ensuring safe and efficient operation. It should be noted that, as an alternative implementation, the switch 9 can also be slidably disposed on the outer side wall of the disassembly member 1 in the radial direction of the disassembly member 1. One end of the switch 9 is connected to the limiting member 3. By pulling the switch 9 outward, the protrusion 4 of the limiting member 3 releases the limiting of the nut.
[0046] The switch 9 is located at one end of the disassembly part 1, and the opening is located at the other end, which is convenient for one-handed operation. The elastic element 10 is set to easily reset the limit element 3, ensuring that the limit element 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 extension rods. The fixed plate is arranged parallel to the switch member 9, and the switch member 9 is mounted on the fixed plate. Multiple extension rods are provided, extending from the outer edge of the fixed plate towards the opening. The fixed plate is circular. The extension rods can elastically deform under external force, and have a force that moves towards the center position of the disassembly member 1. A protrusion 4 is provided on the side of the extension rod facing the first receiving cavity 2, at which time the protrusion 4 extends from the through hole 8 into the first receiving cavity 2. The extension rods are vertically arranged on the fixed plate. By providing multiple extension rods on the fixed plate, the nut can be effectively limited at multiple angles, enhancing the stability and adaptability of the structure. It should be noted that, as an alternative implementation, the number of extension rods can be set to three at intervals. It should also be noted that, as an alternative implementation, 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 9 and the limiting member 3. The insulating layer 11 is epoxy resin. Epoxy resin is also provided on the outer surface of the disassembly member 1. When used in a high-voltage electrical environment, such as a 380V electrical environment, the metal disassembly member 1 needs to avoid contact with the human body to prevent electric shock. By providing an insulating layer 11 between the switch 9 and the limiting member 3, the disassembly member 1 can disassemble the live nut. At this time, the person can hold the epoxy resin of the disassembly member 1 and disassemble the live nut. Afterwards, when pressing the switch 9, since an insulating layer 11 is also provided between the switch 9 and the limiting member 3, electric shock to the human body through the switch 9 can be prevented. It should be noted that, as an alternative implementation, the insulating layer 11 and the insulating material on the outer surface of the disassembly member can also be other materials, such as polyurethane foam.
[0049] like Figure 2As shown, in this embodiment, the upper end face of the insulating layer 11 has a first locking post 12 extending toward the switch member 9, and the switch member 9 has a first locking groove that is inserted and connected to the first locking post 12. The lower end face of the insulating layer 11 has a second locking post 13 extending toward the limiting member 3, and the fixing plate has a second locking groove that is inserted and connected to the second locking post 13. Both the first locking post 12 and the second locking post 13 are cylindrical, and multiple first locking posts 12 and second locking posts 13 are arranged in a circumferential array on the upper and lower end faces of the insulating layer 11, respectively. Correspondingly, multiple first locking grooves and second locking grooves are also provided. The first locking grooves and second locking grooves are also circular. By setting the first locking post 12 and the first locking groove, the horizontal displacement of the insulating layer 11 is limited by the first locking post 12, which can achieve a more stable locking connection between the insulating layer 11 and the switch member 9. By setting the second locking post 13 and the second locking groove, the horizontal displacement of the insulating layer 11 is limited, which can achieve a more stable locking connection between the insulating layer 11 and the limiting member 3. It should be noted that, as an alternative implementation, the first snap-fit post 12 and the second snap-fit post 13 can also be square in shape.
[0050] like Figure 2 As shown, in this embodiment, the cross-section of the first receiving cavity 2 of the disassembly component 1 is hexagonal. By setting the cross-section of the first receiving cavity 2 to hexagonal, it is convenient to accurately position and disassemble the hexagonal nut, improving the convenience and accuracy of operation. The hexagonal cross-section design matches the shape of the nut, reducing sliding errors and improving gripping stability. It should be noted that, as an alternative implementation, the cross-section of the first receiving cavity 2 of the disassembly component 1 can also be set to the shape of other nuts, such as octagonal.
[0051] Specifically, the disassembly component 1 is made of metal, preferably 45# steel. The fixing plate is made of thin steel, and the extension rod is made of 65Mn spring steel with a surface hardened to a hardness of HRC45-50, ensuring its elasticity and durability. The disassembly component 1 is a cylinder with an open end and a switch 9 at the other end. The switch 9 slides along the length of the disassembly component 1. An elastic element 10 is provided between the limiting component 3 and the disassembly component 1. The elastic element 10 is located on the side of the limiting component 3 away from the switch 9, and it is a spring. Through the spring force, the limiting component 3 can quickly reset after being released from its limit.
[0052] This utility model relates to a sleeve for easy nut removal, the installation process of which is as follows: First, the elastic element 10 is installed on the side of the limiting element 3 away from the switch element 9, ensuring that one end of the elastic element 10 is fixed to the removal part 1 and the other end contacts the limiting element 3, providing the limiting element 3 with the necessary thrust. Next, the limiting element 3 is precisely installed into the second receiving cavity 7 of the removal part 1, ensuring that it can slide smoothly along the length direction of the removal part 1. Then, the switch element 9 is installed on the end of the removal part 1 away from the opening, ensuring that it is connected to the limiting element 3 to effectively control the movement of the limiting element 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 receiving cavity 2 to effectively limit the nut. In addition, it is also necessary to confirm that the cross-section of the first receiving cavity 2 of the removal part 1 matches the shape of the nut to be removed.
[0053] The working principle of the sleeve that facilitates nut removal: (e.g.) Figure 2 As shown, in use, the nut to be removed is first placed into the disassembly cavity 6 at the opening of the disassembly component 1. At this time, the protrusion 4 of the limiting component 3 extends out of the through hole 8 and abuts against the upper end face of the nut, limiting the nut in the axial direction. Subsequently, by rotating the disassembly component 1, the nut is unscrewed from the stud by utilizing the friction between the disassembly component 1 and the nut.
[0054] After the nut is successfully removed, the disassembly piece 1 is moved forcefully along the axial direction of the stud toward the nut. Due to the constraint of the stud, the nut will not shift, but will press against the protrusion 4 of the limiting piece 3. After being pressed, the protrusion 4 will move radially outward, causing the limiting piece 3 to contract. When the protrusion of the protrusion 4 is flush with the inner surface of the first receiving cavity 2, the nut can smoothly enter the storage cavity 5 from the disassembly cavity 6 (e.g., Figure 3 (As shown).
[0055] The storage cavity 5 allows disassembled nuts to be collected within it, preventing them from falling out. Simultaneously, the limiting member 3 and through hole 8 ensure effective restraint of the nuts during disassembly. The switch member 9 is connected to the limiting member 3 to control its movement. The elastic member 10 and the switch member 9 are located on opposite sides of the fixing plate of the limiting member 3. The elastic member 10 faces the opening, and its two ends are connected to the fixing plate and the disassembly member 1, respectively. The elastic member 10 exerts a force that drives the limiting member 3 away from the opening. When it is necessary to clean the nuts in the storage cavity 5, simply press the switch member 9, causing the limiting member 3 to move towards the opening. At this time, the elastic member 10 is compressed, and the protrusion 4 disengages from the through hole 8, releasing the restraint on the nuts. Subsequently, the nuts in the storage cavity 5 can be detached from the disassembly member 1. After the switch 9 is released, the limiter 3 automatically resets under the action of the elastic element 10, and the protrusion 4 re-enters the through hole 8, restoring the limiting function for the nut.
[0056] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
