Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary nuts, in particular to an auxiliary disassembly sleeve. Background Art

[0002] The auxiliary disassembly and assembly socket is a socket structure provided for disassembling and assembling nuts or bolts. At present, the auxiliary disassembly and assembly socket includes traditional sockets, universal sockets, mechanical single-track sockets, electromagnetic sockets and other sockets.

[0003] The current sleeve structure has the following disadvantages: 1) Few installation models: Traditional sleeves have relatively few sizes and models. When facing some special specifications or models of equipment, it may not be possible to provide suitable sleeves. This requires users to purchase multiple different models of sleeves to meet different usage requirements, thereby increasing the user's purchase cost and inventory management burden; 2) Multiple sleeve heads lead to high costs: In order to adapt to a variety of different usage scenarios, traditional sleeves usually provide multiple sleeve heads. Users need to choose the appropriate sleeve head according to actual conditions. This leads to the user needing to purchase more sleeve heads, increasing costs. Moreover, the management and replacement of multiple sleeve heads are relatively troublesome, further increasing the cost of use; 3) On-site management is not easy: At the construction site, there are certain problems with the storage and carrying of traditional sleeves. Due to the large number of sleeve models and types, on-site managers need to classify and manage the sleeves to ensure that they can quickly find suitable sleeves when needed. This not only increases the workload of on-site management, but also may lead to reduced work efficiency. At the same time, traditional sleeves may need to be replaced during use. When there are no spare sleeves on site, it may affect the maintenance progress.

[0004] In order to improve the above shortcomings, the prior art uses a universal socket to disassemble and assemble nuts or bolts. The universal socket adapts to bolts and nuts of different sizes through an adjustable gear and rack inside. When the handle is rotated, the gear and rack will move to adjust the size of the socket. When the size of the socket matches the size of the bolt or nut, the universal socket can be used to disassemble or install them.

[0005] However, the universal socket in the prior art has the following disadvantages: 1) It cannot be used in a narrow space: Traditional universal sockets are usually relatively large, and the use in a narrow space is not taken into consideration during the design. In the narrow space where the universal socket is needed, it may not be smoothly inserted or sleeved onto the equipment or component that needs to be repaired, which limits the use scenarios and practicality of the traditional universal socket; 2) Easy to slide: When designing the traditional universal socket, the stability during use is not fully considered. During operation, especially when a certain force needs to be applied, the traditional universal socket is easy to slide, resulting in the inability to stably fix on the component that needs to be repaired during the repair process, thereby increasing the difficulty and time of the repair, which not only affects the repair efficiency, but also may cause accidents during the repair process, causing secondary damage to the equipment or components.

[0032] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0033] Please refer to Figures 1 to 9The utility model provides an auxiliary disassembly sleeve, comprising a mounting sleeve 1 and a disassembly component 2, wherein the mounting sleeve 1 has a mounting sleeve cavity 11; the disassembly component 2 is movably arranged in the mounting sleeve cavity 11 so that the disassembly component 2 has an initial position and a disassembly position; when the disassembly component 2 is located at the initial position, the disassembly component 2 is located in the mounting sleeve cavity 11; when the disassembly component 2 is located at the disassembly position, at least part of the disassembly component 2 extends out of the mounting sleeve cavity 11 to disassemble the component to be disassembled.

[0034] The utility model provides an auxiliary disassembly sleeve, which comprises a mounting sleeve 1 and a disassembly component 2. The disassembly component 2 is movably arranged in a mounting cylinder cavity 11 so that the disassembly component 2 has an initial position and a disassembly position. When the disassembly component 2 is located at the initial position, the disassembly component 2 is located in the mounting cylinder cavity 11. When the disassembly component 2 is located at the disassembly position, at least part of the disassembly component 2 extends out of the mounting cylinder cavity 11 so as to disassemble and assemble the component to be disassembled. By reducing the wall thickness of the disassembly component 2, it is convenient to operate a bolt or nut arranged in a narrow space when the disassembly component 2 is located at the disassembly position, so that the bolt or nut matched with the disassembly component 2 is installed on the mounting base or the bolt or nut installed on the mounting base is removed, thereby solving the problem that the sleeve structure in the prior art is not convenient for disassembling and assembling the bolt or nut in a narrow space.

[0035] In the first embodiment:

[0036] Specifically, Figure 7 and Figure 8 As shown, in order to facilitate the disassembly and assembly component 2 to move to the initial position or the disassembly and assembly position, a guide groove 12 connected to the installation cylinder cavity 11 is provided on the circumferential side wall of the installation sleeve 1; the auxiliary disassembly and assembly sleeve also includes a pushing component 3, which is connected to the disassembly and assembly component 2, and the pushing component 3 is movably arranged along the guide groove 12 to drive the disassembly and assembly component 2 to move along the guide groove 12.

[0037] Among them, the pushing component 3 is telescopically arranged along a direction perpendicular to the axial direction of the installation sleeve 1, so as to have a positioning state and a sliding state; when the pushing component 3 is in the positioning state, the pushing component 3 is clamped in the guide slot 12, so as to keep the disassembly component 2 in the initial position or the disassembly position; when the pushing component 3 is in the sliding state, the pushing component 3 is movably arranged along the guide slot 12, so as to drive the disassembly component 2 to move to the initial position or the disassembly position. By arranging the pushing component 3, it is convenient to push the disassembly component 2 while keeping the disassembly component 2 in the initial position or the disassembly position, so as to enhance the stability of the disassembly component 2 during use and prevent the disassembly component 2 from sliding relative to the installation sleeve during use. Figure 7As shown, when the disassembly component 2 is in the initial position, the installation sleeve 1 protects the disassembly component 2; Figure 8 As shown, when the disassembly component 2 is located at the disassembly position, the wall thickness of the disassembly component 2 is reduced so that the disassembly component 2 can be inserted into a narrow space to disassemble the components to be disassembled in the narrow space.

[0038] Furthermore, in order to lock the pushing component 3, as shown in FIG. Figure 5 As shown, the pushing component 3 includes a sliding rod 31 and a self-locking block 32 which are connected to each other, and the self-locking block 32 is connected to the disassembly component 2; at least part of the self-locking block 32 protrudes along the circumference of the sliding rod 31; wherein the radial dimension of the sliding rod 31 is d1, and the radial dimension of the self-locking block 32 along the sliding rod 31 is d2, and d2>d1.

[0039] Optionally, the specific structure of the pushing component 3 in the embodiment of the present application is:

[0040] A specific structure is: the self-locking block 32 is a cylindrical structure, the sliding rod 31 is a rod-shaped structure, and the radial dimension of the self-locking block 32 is greater than the radial dimension of the sliding rod 31 .

[0041] Another specific structure is that the self-locking block 32 is a protruding block, the sliding rod 31 is a rod-shaped structure, and the self-locking block 32 protrudes in a direction away from the side wall of the sliding rod 31 .

[0042] Specifically, in order to make the self-locking block 32 stuck in the guide slot 12, as shown in FIG. Fig. 9 As shown, the guide slide groove 12 includes a first locking section 121, a sliding section 122 and a second locking section 123 which are connected in sequence, the sliding section 122 extends along a first direction, and the sliding rod 31 is movably arranged along the extension direction of the sliding section 122; the length dimension of the sliding section 122 along the second direction is d3, d3≥d1; the length dimension of the first locking section 121 along the second direction is d4, d4>d3 and d4≥d2; the first direction is perpendicular to the second direction; the second locking section 123 has the same structure as the first locking section 121.

[0043] When the disassembly component 2 is at the initial position, the self-locking block 32 is locked in the first locking section 121 to keep the pushing component 3 in a fixed position; when the disassembly component 2 is at the disassembly position, the self-locking block 32 is locked in the second locking section 123 to keep the pushing component 3 in a fixed position; when the sliding rod 31 moves along the sliding section 122, the pushing component 3 is in a sliding state, thereby preventing the disassembly component 2 from sliding out of or into the installation cylinder cavity 11 under the action of its own gravity.

[0044] Generally, the sliding section 122 is a bar-shaped slideway; the first locking section 121 is a circular through hole communicating with the sliding section 122 ; and the second locking section 123 is a circular through hole communicating with the sliding section 122 .

[0045] Optionally, the first locking section 121 is arranged at one end of the sliding section 122 close to the bottom of the installation barrel cavity 11, so that when the self-locking block 32 is located in the first locking section 121, the disassembly component 2 is located in the initial position; the second locking section 123 is arranged at one end of the sliding section 122 close to the opening of the installation barrel cavity 11, so that when the self-locking block 32 is located in the second locking section 123, the disassembly component 2 is located in the disassembly position; wherein, the specific arrangement of the sliding section 122 is as follows:

[0046] A specific arrangement is as follows: the sliding section 122 extends in a straight axial direction of the mounting sleeve 1, and the pushing component 3 drives the disassembly component 2 to be movably arranged along the sliding section 122, so as to reduce the moving distance of the disassembly component 2 and improve efficiency.

[0047] Another specific arrangement is that the sliding section 122 is spirally arranged along the axial direction of the installation sleeve 1, and the pushing component 3 moves along the sliding section 122 to drive the disassembly component 2 to rotate, so that the disassembly component 2 can be screwed out of the installation sleeve 1 for easy operation.

[0048] Furthermore, in order to make the pushing component 3 telescopically arranged along the axis perpendicular to the installation sleeve 1, the auxiliary disassembly sleeve also includes an elastic member 4 and a limiting member 5. The elastic member 4 has two ends along the telescopic direction of the elastic member 4; the two ends of the elastic member 4 are respectively connected to the disassembly component 2 and the self-locking block 32, and a force is applied to the pushing component 3 along the telescopic direction of the elastic member 4 so that the self-locking block 32 is retracted into the installation cylinder cavity 11, so that the pushing component 3 is switched from the positioning state to the sliding state; under the action of the rebound force of the elastic member 4, the self-locking block 32 is extended, so that the pushing component is switched from the sliding state to the positioning state; the limiting member 5 is connected to the disassembly component 2, and the limiting member 5 is The elastic member 4 is arranged circumferentially so that the elastic member 4 and the portion where the pushing member 3 is connected to the elastic member 4 are located in the limiting space 51 of the limiting member 5, so that the limiting member 5 limits the pushing member 3. Since the elastic member 4 is a flexible member, the pushing member 3 and the disassembling member 2 are flexibly connected. In order to prevent the pushing member 3 from deviating from the predetermined motion track when the operator applies a force along the extension and contraction direction of the elastic member 4, the limiting member 5 is provided to limit the pushing member 3. At the same time, the pushing member 3 is pushed so that when it moves along the guide groove 12, the setting of the limiting member 5 makes it easier for the pushing member 3 to drive the disassembling member 2 to move.

[0049] Preferably, the elastic member 4 is a telescopic spring; the limiting component 5 is a cylindrical structure, the bottom of the cylindrical structure is connected to the disassembly component 2, and the limiting space 51 is a cylindrical cavity of the cylindrical structure, so that the limiting component 5 limits the pushing component 3 along its circumference.

[0050] In addition, in order to facilitate the operation of the pushing component 3, the pushing component 3 also includes a limit block 33, which is connected to the sliding rod 31. The limit block 33 is arranged on the outside of the mounting sleeve 1 to drive the disassembly component 2 to move by pushing the limit block 33; at least part of the limit block 33 protrudes along the circumference of the sliding rod 31; wherein, the radial dimension of the limit block 33 along the sliding rod 31 is d5, d5>d2.

[0051] The specific structure of the limit block 33 in the embodiment of the present application is as follows:

[0052] The first specific structure is: the part of the limit block 33 protruding from the sliding rod 31 is different in shape from the part of the self-locking block 32 protruding from the sliding rod 31, so as to stop the limit block 33 on the outside of the mounting sleeve 1 to prevent the limit block 33 from retracting into the first locking section 121 or the second locking section 123 when the limit block 33 is pushed, thereby preventing the limit block 33 from being stuck in the mounting cylinder cavity 11 and being inconvenient to remove.

[0053] The second specific structure is: the position of the portion of the limit block 33 protruding from the sliding rod 31 is different from the position of the portion of the self-locking block 32 protruding from the sliding rod 31, so as to stop the limit block 33 on the outside of the mounting sleeve 1 to prevent the limit block 33 from retracting into the first locking section 121 or the second locking section 123 when the limit block 33 is pushed, so as to avoid the limit block 33 being stuck in the mounting cylinder cavity 11 and being inconvenient to remove.

[0054] The third specific structure is: the size of the part of the limit block 33 protruding from the sliding rod 31 is larger than the size of the part of the self-locking block 32 protruding from the sliding rod 31, so as to stop the limit block 33 on the outside of the mounting sleeve 1 to prevent the limit block 33 from retracting into the first locking section 121 or the second locking section 123 when the limit block 33 is pushed, so as to avoid the limit block 33 being stuck in the mounting tube cavity 11 and being inconvenient to remove.

[0055] Specifically, Figure 6 As shown, the disassembly and assembly component 2 in the embodiment of the present application includes a disassembly and assembly part 21 and a connecting part 22. The disassembly and assembly part 21 has a disassembly and assembly cavity 211, which is used to clamp the component to be disassembled in the disassembly and assembly cavity 211; the connecting part 22 is connected to the disassembly and assembly part 21, and the connecting part 22 is connected to the pushing part 3, so that the movement of the pushing part 3 drives the movement of the connecting part 22.

[0056] like Figure 1 and Figure 2As shown, the disassembly part 21 is a cylindrical structure; there are multiple disassembly parts 2, and the multiple disassembly parts 21 are nested in sequence along the radial direction of the installation sleeve 1, so that when the multiple disassembly parts 2 are in the initial position, the multiple disassembly parts 21 are stacked in the installation cylinder cavity 11; so that when one of the multiple disassembly parts 2 is in the disassembly position, the part to be disassembled is disassembled. It is suitable for parts to be disassembled of different models and sizes, and operates on parts to be disassembled of different models and sizes.

[0057] Furthermore, there are multiple guide grooves 12, and the multiple guide grooves 12 are arranged at intervals along the circumference of the mounting sleeve 1; there are multiple pushing components 3, and the multiple pushing components 3 are connected to the multiple disassembly components 2 one by one, and the multiple pushing components 3 are inserted into the multiple guide grooves 12 one by one, so as to push the pushing components 3 connected to each disassembly component 2 to push the required disassembly component 2 to the disassembly position.

[0058] Preferably, the plurality of disassembly and assembly parts 2 include an M8 disassembly and assembly part 71, an M10 disassembly and assembly part 72, an M12 disassembly and assembly part 73 and an M14 disassembly and assembly part 74, so as to respectively disassemble and assemble M8 nuts or bolts, M10 nuts or bolts, M12 nuts or bolts and M14 nuts or bolts.

[0059] In the second embodiment:

[0060] The specific structure of the auxiliary disassembly sleeve in the embodiment of the present application is the same as that in the first embodiment, except that the pushing component 3 in the present embodiment can be connected to the driving component, and the driving component drives the pushing component 3 to drive the disassembly component 2 to move to the initial position or the disassembly position. This arrangement is convenient for operation and improves work efficiency, but the structure is more additional, which increases the manufacturing cost and is suitable for large-scale work. The driving component is an electric push rod.

[0061] In a third embodiment:

[0062] The specific structures of the installation sleeve 1, the disassembly component 2 and the pushing component 3 of the auxiliary disassembly sleeve in the embodiment of the present application are the same as those in the first embodiment. The difference is that the pushing method of the multiple disassembly components 2 in this embodiment is different from that in the first embodiment.

[0063] Specifically, there are multiple disassembly and assembly components 2 in this embodiment, and the protruding length of the connecting portion 22 of each disassembly and assembly component 2 is shortened successively along the extension direction of the installation cylinder cavity 11. The pushing component 3 is connected to each connecting portion 22, and the guide slide groove 12 has a plurality of connected second locking segments 123 and a plurality of sliding segments 122. The plurality of sliding segments 122 and the plurality of second locking segments 123 are arranged at intervals in a direction away from the first locking segment 121, so that when the pushing component 3 is stuck in each second locking segment 123, each disassembly and assembly component 2 can be pushed out. Such an arrangement is simpler and reduces the manufacturing cost, but reduces the reliability of the disassembly and assembly component 2 and increases the operation complexity.

[0064] From the above description, it can be seen that the above embodiments of the utility model achieve the following technical effects:

[0065] The utility model provides an auxiliary disassembly sleeve, which comprises a mounting sleeve 1 and a disassembly component 2, wherein the mounting sleeve 1 has a mounting sleeve cavity 11; the disassembly component 2 is movably arranged in the mounting sleeve cavity 11. By movably arranging the disassembly component 2 in the mounting sleeve cavity 11, the disassembly component 2 has an initial position and a disassembly position; when the disassembly component 2 is located at the initial position, the disassembly component 2 is located in the mounting sleeve cavity 11; when the disassembly component 2 is located at the disassembly position, at least part of the disassembly component 2 extends out of the mounting sleeve cavity 11 to disassemble the component 2 to be disassembled; by reducing the wall thickness of the disassembly component 2, when the disassembly component 2 is located at the disassembly position, it is convenient to operate the bolts or nuts arranged in a narrow space, so that the bolts or nuts adapted to the disassembly component 2 are installed on the mounting base or the bolts or nuts installed on the mounting base are removed, thereby solving the problem that the sleeve structure in the prior art is not convenient for disassembling the bolts or nuts in a narrow space.

[0066] The utility model provides a self-locking block 32 of the pushing component 3 and a first locking section 121 and a second locking section 123 provided on the side wall of the mounting sleeve 1 and adapted to the self-locking block 32, so that the pushing component 3 has a positioning state and a sliding state. Therefore, when the disassembling component 2 is used, the disassembling component 2 is locked in the disassembling position to prevent the disassembling component 2 from sliding due to the application of external force during the operation, thereby enhancing stability, improving maintenance efficiency, and avoiding secondary damage to the equipment or the user.

[0067] The utility model also nests a plurality of disassembly and assembly components 2 of different sizes in sequence in the installation cylinder cavity 11, so that when bolts or nuts of different models and sizes need to be disassembled and assembled, the disassembly and assembly components 2 adapted thereto can be pushed out to the disassembly and assembly position for disassembly and assembly. Such an arrangement allows for free selection of disassembly and assembly components 2 of different sizes, is convenient to operate, easy to use, reduces operating costs, and improves work efficiency.

[0068] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
