Description

Technical Field

[0001] This utility model relates to the field of bolt disassembly technology, specifically a simple coupling bolt disassembly device. Background Technology

[0002] A coupling is a device that connects two shafts or a shaft and a rotating component, allowing them to rotate together during motion and power transmission. Under normal circumstances, they do not disengage. Sometimes, they also serve as a safety device to prevent the connected components from bearing excessive loads, providing overload protection. A coupling is also briefly described as a joint.

[0003] Bolts are typically used for connection during coupling installation. Bolt specifications vary, and traditional bolt removal tools have significant limitations when the equipment needs maintenance after long-term operation: since a single tool set is only compatible with a specific bolt size, when multiple bolt sizes are used in a coupling, the removal tools must be changed repeatedly; the frequent tool changes not only reduce maintenance efficiency, but also pose safety risks when operating in a confined space. Utility Model Content

[0004] The purpose of this utility model is to provide a simple coupling bolt removal device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a simple coupling bolt disassembly device, including a support rod, a replacement mechanism at the bottom of the support rod, a sleeve at the bottom of the replacement mechanism, and a storage mechanism on the outside of the support rod;

[0006] The replacement mechanism includes a first externally threaded tube, which is fixedly connected to the bottom end. A first positioning ring is fixedly connected to the outer wall of the first externally threaded tube. An internally threaded tube is threadedly connected to the outer wall of the first externally threaded tube. An external spline is fixedly connected to the bottom of the first externally threaded tube. A torsion block is fixedly connected to the outer wall of the internally threaded tube. An internal spline engages with the outer wall of the external spline. A second externally threaded tube is fixedly connected to the outer wall of the internal spline. A second positioning ring is fixedly connected to the outer wall of the second externally threaded tube.

[0007] The internal spline and the second external threaded tube are both fixedly connected to the top of the sleeve. The internal threaded tube is threaded to the outer wall of the second external threaded tube. Through the connection and cooperation of the second external threaded tube, the internal threaded tube and the first external threaded tube, the installation and connection of the support rod and the sleeve can be realized.

[0008] The outer wall of the torsion block is fixedly connected with a protrusion, which facilitates better rotation of the torsion block.

[0009] The storage mechanism includes a rectangular groove, which is formed on the outer wall of the support rod. A T-shaped shaft is rotatably connected to the inner wall of the rectangular groove. A handle is fixedly connected to the outer wall of the T-shaped shaft. A torsion sleeve is threadedly connected to the outer wall of the T-shaped shaft. An opening is provided on the front of the support rod to facilitate better control of the rotation of the support rod.

[0010] The back of the torsion sleeve is in close contact with the inner wall of the opening, and a knob is fixedly connected to the front of the T-shaped shaft, which facilitates the rotation of the T-shaped shaft by turning the knob.

[0011] A through hole is provided on one side of the rectangular groove and the opening that are close to each other. The T-shaped shaft passes through the through hole and rotates, providing stable support for the T-shaped shaft.

[0012] The handle is located on the inner wall of the rectangular groove, which makes it easy to store the handle and reduce the space occupied by the support rod.

[0013] Compared with the prior art, this utility model provides a simple coupling bolt removal device, which has the following advantages:

[0014] 1. This utility model achieves rapid and reliable connection and replacement of sleeves and support rods by setting up a replacement mechanism composed of a first external threaded pipe, an internal threaded pipe, an external spline, and an internal spline. The beneficial effect of this structure is that operators do not need to carry or replace the entire disassembly tool. They can quickly disassemble and install sleeves of different specifications by simply rotating the torsion block, thereby adapting to bolts of various sizes on the coupling, improving maintenance efficiency, and reducing tool purchase and carrying costs. At the same time, the spline meshing structure ensures the stability of torque transmission and construction safety.

[0015] 2. This utility model features a storage mechanism consisting of a T-shaped shaft, a torsion sleeve, and a retractable handle, allowing the lever handle to rotate 90 degrees and be completely retracted into a rectangular slot. The advantages of this structure are that, in its non-use state, it significantly reduces the overall size of the tool, making it easy to store and carry; in use, the extended handle provides the operator with ample leverage, and in space-constrained working environments, the handle can be left closed, allowing operation directly using the support rod. This greatly enhances adaptability to different working conditions and solves the problem of traditional tools being unable to operate in confined spaces due to excessively long handles.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model provides the following technical solution:

[0024] Example 1

[0025] Combination Figures 1 to 5 A simple coupling bolt disassembly device includes a support rod 1, a replacement mechanism 3 at the bottom of the support rod 1, a sleeve 2 at the bottom of the replacement mechanism 3, and a storage mechanism 4 on the outside of the support rod 1. By integrating the replacement mechanism 3 and the storage mechanism 4 onto the support rod 1, a compact integrated tool is formed. This not only enables the rapid replacement of the sleeve to adapt to coupling bolts of different specifications, but also allows for convenient storage of the operating handle, significantly improving the versatility and portability of the equipment. A single tool can handle a variety of working conditions.

[0026] The replacement mechanism 3 includes a first external threaded tube 31, which is fixedly connected to the bottom end. A first positioning ring 32 is fixedly connected to the outer wall of the first external threaded tube 31. An internal threaded tube 33 is threadedly connected to the outer wall of the first external threaded tube 31. An external spline 34 is fixedly connected to the bottom of the first external threaded tube 31. A torsion block 38 is fixedly connected to the outer wall of the internal threaded tube 33. An internal spline 35 engages with the outer wall of the external spline 34. A second external threaded tube 36 is fixedly connected to the outer wall of the internal spline 35. A second positioning ring 37 is fixedly connected to the outer wall of the second external threaded tube 36. By combining threaded connection and spline engagement, the first positioning ring 32 and the second positioning ring 37 ensure accurate alignment and reliable axial positioning during connection. The spline engagement ensures that the torque will not slip during transmission, thereby enhancing the stability and safety of disassembly operations.

[0027] The internal spline 35 and the second external threaded tube 36 are both fixedly connected to the top of the sleeve 2. The internal threaded tube 33 is threaded to the outer wall of the second external threaded tube 36, so that one set of support rod 1 can match multiple working modules that only need to replace the sleeve 2. Users do not need to purchase the whole set of tools, but only need to select the sleeve of the corresponding specification, which effectively reduces the cost of using tools and storage space.

[0028] The outer wall of the torsion block 38 has a protrusion for fixed connection. The protrusion design on the outer wall of the torsion block 38 significantly increases the friction during operation. Even when wearing gloves or with oily hands, it can be easily rotated, achieving fast, labor-saving and reliable assembly and disassembly operations.

[0029] Example 2

[0030] See Figures 1 to 5 Furthermore, based on Embodiment 1, the storage mechanism 4 further includes a rectangular groove 41, which is opened on the outer wall of the support rod 1. A T-shaped shaft 42 is rotatably connected to the inner wall of the rectangular groove 41. A handle 43 is fixedly connected to the outer wall of the T-shaped shaft 42. A torsion sleeve 44 is threadedly connected to the outer wall of the T-shaped shaft 42. An opening 45 is opened on the front of the support rod 1. The rectangular groove 41 provides a perfect storage space for the handle 43. Combined with the rotation function of the T-shaped shaft 42, the handle can be flexibly switched between the two states of "unfolded operation" and "hidden storage", which completely solves the pain points of long-handled tools being inconvenient to carry and difficult to store.

[0031] The back of the torsion sleeve 44 is in close contact with the inner wall of the opening 45, and the front of the T-shaped shaft 42 is fixedly connected to a knob. By rotating the torsion sleeve 44, the handle 43 can be locked and released, making the operation extremely simple and intuitive. The knob design on the front of the T-shaped shaft 42 facilitates operation by hand, allowing the handle angle to be adjusted and fixed without the need for other tools, greatly improving the ease of operation.

[0032] A through hole is provided on one side of the rectangular groove 41 and the opening 45 that are close to each other. The T-shaped shaft 42 passes through the through hole and rotates. The through hole structure provides through support for the T-shaped shaft 42, making the force more even and effectively preventing shaft deformation or wear caused by uneven force. This greatly enhances the mechanical strength and long-term reliability of the storage mechanism.

[0033] The handle 43 is set on the inner wall of the rectangular slot 41, which makes it easy to store the handle 43. When the handle 43 is completely stored in the rectangular slot 41, the overall shape of the tool tends to be a straight rod, which optimizes its layout in the toolbox, facilitates transportation and storage, and is especially suitable for use in on-site repair situations with limited space.

[0034] In actual operation, when this device is in use, the torsion sleeve 44 can be rotated so that it is no longer pressed against the inner wall of the opening 45. At this time, the T-shaped shaft 42 can be rotated. Then, the knob on the front of the T-shaped shaft 42 can be used to drive the T-shaped shaft 42 to rotate. The T-shaped shaft 42 drives the handle 43 to rotate 90 degrees along the axis of the T-shaped shaft 42, so that the handle 43 can be pulled out from the inside of the rectangular groove 41. Then, the torsion sleeve 44 is rotated in the opposite direction again so that it presses against the inner wall of the opening 45 again, thereby fixing the handle 43 and allowing the two handles 43 to be set in parallel. Then, the sleeve 2 is inserted into the outer wall of the coupling. Then, the support rod 1 can be rotated through the two handles 43, thereby achieving the purpose of rotating and disassembling the coupling bolts. At the same time, when not in use, the handle 43 can be retracted to reduce the space occupied by the handle 43 and facilitate storage and carrying.

[0035] Rotating the external spline 34 causes the internal threaded tube 33 to rotate. Since the internal threaded tube 33 and the first external threaded tube 31 are threadedly connected, the internal threaded tube 33 can move and rise from the outer wall of the second external threaded tube 36. When the internal threaded tube 33 is completely unscrewed from the outer wall of the second external threaded tube 36, the internal spline 35 can be unscrewed from the outer wall of the external spline 34 through the sleeve 2, thus achieving the disassembly of the sleeve 2. Similarly, the sleeve 2 can also be installed. This allows for the replacement of different models of sleeve 2 with different sizes of coupling bolts without replacing the entire device. At the same time, the meshing of the internal spline 35 and the external spline 34 can ensure the stability of torque transmission during the disassembly of the coupling bolts.
