Description

Technical Field

[0001] This utility model relates to the field of relay winding technology, and more specifically, to an anti-tangle cable storage box for relay protection devices. Background Technology

[0002] Although existing relay winding equipment has been continuously innovated and developed to basically meet people's needs, there is still room for improvement.

[0003] The existing technology uses multiple sets of fixing plates arranged evenly on the periphery of the housing. A top cover is also fitted onto the housing, and wire inlet holes are opened on both sides of the housing. A mounting post is also provided between the two sets of wire inlet holes, and a winding assembly is detachably installed between the mounting post and the top cover. A first fixing hole and a second fixing hole are opened on the sides of the housing and the top cover respectively. The fixing assembly passes through the first fixing hole and the second fixing hole and is installed inside the housing. It adopts a detachable structure, which eliminates the need for disassembly of the entire device and time-consuming operations. Only the top cover needs to be removed to carry out maintenance, replacement or repair work.

[0004] Existing cable storage boxes allow for quick disassembly of the box body and lid, but disassembly requires manual control of two limiting parts before removing the lid, making the operation complicated. Especially when the box body is large, both hands are needed to operate the limiting parts at different positions, making it difficult to free up hands to remove the lid, which is still somewhat inconvenient in actual use. Utility Model Content

[0005] The present invention aims to provide an anti-tangle cable storage box for relay protection devices, so as to solve the problems of complicated disassembly and removal of the box body and cover in the prior art, and the difficulty in removing the cover after manipulating the limiting part with both hands when the box body is large, and the inconvenience of use.

[0006] The embodiments of this utility model are implemented as follows:

[0007] This utility model provides an anti-tangle cable storage box for a relay protection device, which includes a cable winding mechanism and a cable take-up mechanism.

[0008] The above-mentioned cable take-up mechanism has a box body and a box cover. The side of the box body is provided with a cable routing hole. The box cover is placed at the opening of the box body. The outer edge of the box cover can be rotatably pressed against the inner wall of the box body.

[0009] The outer edge of the box cover is provided with a limiting ring groove with insert holes. The opening of the box body is connected with the same number of limiting pieces as the insert holes. The limiting pieces are slidably adapted to the limiting ring groove.

[0010] The winding mechanism has a winding post located inside the box and a handle located outside the box. The handle is located on the side of the box away from the box cover. The end of the winding post near the box can rotatably pass through the bottom surface of the box and is fixedly installed on one end of the handle.

[0011] In use, the lid is placed at the opening of the box body, and with the limiting piece, it can slide through the insert hole and into the limiting ring groove, thereby completing the disassembly and fixing of the lid and the box body. By rotating the lever of the winding mechanism, the winding post is rotated and the wire is wound. When the device is turned on, only the lid needs to be picked up and rotated, which can be done by one hand, making the operation more convenient.

[0012] The anti-tangle cable storage box for relay protection devices disclosed in this embodiment is equipped with a matching limiting plate and a limiting ring groove. By rotating the box cover, the limiting ring groove of the box cover, in conjunction with the insert hole, can restrict the limiting plate within the limiting ring groove, thereby fixing the box cover to the box body. By rotating the box cover in the opposite direction, the limiting plate is aligned with the insert hole, and the box cover can be separated from the box body simply by lifting the box cover. This makes the anti-tangle cable storage box for relay protection devices easy to disassemble and reassemble, allowing workers to complete the disassembly and operation with one hand, which is more convenient.

[0013] Optionally: the above-mentioned insert hole has a first insert hole and a second insert hole, the first insert hole and the second insert hole are symmetrically distributed, and the first insert hole and the second insert hole are opened along the radial direction of the box cover;

[0014] The aforementioned limiting piece has a first limiting piece and a second limiting piece, the first limiting piece and the second limiting piece are symmetrically distributed and welded to the opening of the aforementioned box body;

[0015] The first limiting piece and the second limiting piece are adapted to the first insert hole and the second insert hole and are slidably embedded in the groove of the limiting ring groove.

[0016] With this configuration, the lid is fixed by aligning the first insert hole and the second insert hole with the first limiting piece and the second limiting piece and pressing them into the opening of the box body. The lid is then rotated so that the first limiting piece and the second limiting piece are located in the limiting ring groove, thereby fixing the lid. Conversely, it is easy to disassemble the lid. By increasing the number of limiting pieces, the fixing effect of the lid is improved.

[0017] Optionally, the surface of the box cover is provided with a plurality of observation holes, all of which penetrate the box cover and are evenly distributed in a ring on the surface of the box cover.

[0018] With this arrangement, the aforementioned observation holes allow staff to observe the positions of the first and second limiting pieces in the limiting ring groove, thereby determining whether the connection between the lid and the body is secure.

[0019] Optionally, both the first limiting piece and the second limiting piece are embedded with magnets, and the lid is made of iron.

[0020] With this configuration, the magnet has a magnetic attraction effect. When the lid is close to the box body, it helps to attract the lid onto the first and second limiting plates, further enhancing the fixing effect of the first and second limiting plates on the lid.

[0021] Optionally, a handle is provided on the side of the lid away from the box body, and the handle is welded to the side of the lid away from the box body.

[0022] With this design, the handle makes it easy for staff to grip the lid, allowing the lid to be rotated and fixed or rotated and removed from the box body, thus facilitating the installation and removal of the lid from the box body.

[0023] Optionally: The edges of the aforementioned wiring holes are curved surfaces.

[0024] This design, with the edges of the aforementioned wiring holes being rounded, makes the wires less prone to wear when passing through the wiring holes and entering the housing, effectively protecting the wires.

[0025] Optionally, a V-shaped groove for clamping the end of the wire is provided at one end of the winding post near the cover, and the V-shaped groove extends along the axial direction of the winding post.

[0026] With this design, the V-shaped groove facilitates the squeezing and clamping of the end of the yarn, allowing the yarn to be wound up when the winding post rotates.

[0027] Optionally, the diameter of the middle section of the winding post is smaller than the diameter of both ends of the winding post.

[0028] This configuration results in the winding post having a smaller diameter in the middle and a larger diameter at both ends, making it easier for the wire to wind around the winding post and making it less likely for the wire to come off the winding post.

[0029] Optionally, a rubber block is fixedly installed on the side of the handle near the box body, and the side of the rubber block near the box body tightly abuts against the side of the box body near the rubber block.

[0030] With this configuration, the rubber block increases frictional damping and enhances the stability of the lever's rotation. When the operator rotates the lever, the rotational force of the lever is greater than the resistance of the rubber block. Therefore, the rubber block does not affect the lever's rotation. When the lever is not rotating, the resistance of the rubber block is greater than the counter-rotational force of the winding thread, effectively preventing the winding thread from loosening.

[0031] Optionally, the cover has a through hole at its axis, and the winding post is rotatably fitted into the through hole at one end near the cover.

[0032] This design effectively prevents the wire from coming off the end of the winding post, and also prevents the cover from rubbing against the winding post.

[0033] Optionally: The outer wall of the aforementioned box body has mounting ears, which are welded to the outer wall of the aforementioned box body.

[0034] With this design, the mounting ears facilitate the securing of the storage box. When removing the lid, simply grasp the lid and rotate it to remove it, achieving quick disassembly, simple operation, and improved convenience.

[0035] Optionally, the end of the lever away from the winding post has a connecting ring.

[0036] With this configuration, the connecting ring allows the operator to easily drive the lever to rotate, thereby rotating the winding post to reel in the line. At the same time, it makes it easy for the operator to install a crank on the connecting ring, making the crank rotation more convenient and effortless.

[0037] In summary, the anti-tangle cable storage box for relay protection devices disclosed in this utility model has the advantages of simple disassembly and assembly of the box body and cover, allowing workers to complete the disassembly and assembly with one hand, making the operation more convenient.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0045] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0046] Example

[0047] See Figure 1 , Figure 2 , Figure 3 and Figure 4 This embodiment proposes an anti-tangle cable storage box for relay protection devices, including a cable winding mechanism 1 and a cable winding mechanism 2;

[0048] The cable take-up mechanism 1 has a box body 3 and a box cover 4. The side of the box body 3 is provided with a cable routing hole 5. The box cover 4 is placed at the opening of the box body 3, and the outer edge of the box cover 4 can be rotatably pressed against the inner wall of the box body 3.

[0049] The outer edge of the box cover 4 is provided with a limiting ring groove 7 with a piece insertion hole 6. The opening of the box body 3 is connected with a limiting piece 8 in the same number as the piece insertion hole 6. The limiting piece 8 can slide to fit the limiting ring groove 7.

[0050] The winding mechanism 2 has a winding post 9 placed inside the box body 3 and a handle 10 placed outside the box body 3. The handle 10 is located on the side of the box body 3 away from the box cover 4. The end of the winding post 9 near the box body 3 can rotatably pass through the bottom surface of the box body 3 and is fixedly installed on one end of the handle 10.

[0051] When in use, the lid 4 is placed at the opening of the box body 3. With the help of the upper limit plate 8, it can slide through the inlet hole 6 and the limiting ring groove 7, thereby completing the disassembly and fixing of the lid 4 and the box body 3. By rotating the lever 10 of the winding mechanism 2, the winding post 9 is rotated and the wire is wound. When this device is opened, only the lid 4 needs to be picked up and rotated, which can be completed by the operator with one hand, making the operation more convenient.

[0052] This embodiment discloses an anti-tangle cable storage box for relay protection devices. Because it is equipped with a matching limiting piece 8 and a limiting ring groove 7, rotating the cover 4 allows the limiting ring groove 7 to engage with the insert hole 6, thus restricting the limiting piece 8 within the limiting ring groove 7. This facilitates the fixing of the cover 4 and the box body 3. Reverse rotation of the cover 4 aligns the limiting piece 8 with the insert hole 6, and simply lifting the cover 4 separates it from the box body 3. Therefore, this anti-tangle cable storage box for relay protection devices offers the advantages of simple disassembly and assembly of the box body 3 and cover 4, allowing workers to complete disassembly and assembly with one hand, making operation more convenient.

[0053] See Figure 1 , Figure 2 , Figure 3 and Figure 4The insert hole 6 has a first insert hole 11 and a second insert hole 12, which are symmetrically distributed and are opened radially along the lid 4. The limiting piece 8 has a first limiting piece 13 and a second limiting piece 14, which are symmetrically distributed and welded to the opening of the box body 3. The first limiting piece 13 and the second limiting piece 14 are adapted to the first insert hole 11 and the second insert hole 12 and are slidably embedded in the groove of the limiting ring groove 7. The lid 4 is fixed by aligning the first insert hole 11 and the second insert hole 12 with the first limiting piece 13 and the second limiting piece 14 and pressing them into the opening of the box body 3. The lid 4 is rotated so that the first limiting piece 13 and the second limiting piece 14 are located in the limiting ring groove 7. Conversely, it is easy to disassemble the lid 4. By increasing the number of limiting pieces, the fixing effect of the lid 4 is improved.

[0054] The surface of the lid 4 is provided with several observation holes 15. The observation holes 15 all penetrate the lid 4 and are evenly distributed in a ring on the surface of the lid 4. The observation holes 15 allow the staff to observe the position of the first limiting piece 13 and the second limiting piece 14 in the limiting ring groove 7, thereby determining whether the connection between the lid 4 and the box body 3 is stable.

[0055] See Figure 1 , Figure 2 , Figure 3 and Figure 4 Both the first limiting piece 13 and the second limiting piece 14 have embedded magnets (not shown in the figure) inside. The lid 4 is an iron component. The magnets have a magnetic attraction effect. When the lid 4 is close to the box body 3, it helps to attract the lid 4 to the first limiting piece 13 and the second limiting piece 14, further improving the fixing effect of the first limiting piece 13 and the second limiting piece 14 on the lid 4.

[0056] A handle 16 is provided on the side of the lid 4 away from the box body 3. The handle 16 is welded to the side of the lid 4 away from the box body 3. The handle 16 makes it convenient for the staff to grip the lid 4, so that the lid 4 can be rotated and fixed or rotated and disassembled on the box body 3, thereby facilitating the installation and removal of the lid 4 on the box body 3.

[0057] The edge of the wiring hole 5 is an arc-shaped surface. Setting the edge of the wiring hole 5 to an arc-shaped surface makes the wire less prone to wear when it passes through the wiring hole 5 and enters the box 3, effectively protecting the wire.

[0058] The outer wall of the box body 3 has mounting ears 20, which are welded to the outer wall of the box body 3. The mounting ears 20 are designed to make it easy to fix the storage box. When removing the box cover 4, you only need to grasp the box cover 4 and rotate it to remove it, which can achieve quick disassembly, simple operation and improved convenience.

[0059] See Figure 1 , Figure 2 , Figure 3 and Figure 4 In this embodiment, the lid 4 is placed at the opening of the box body 3, and the limiting piece 8 can slide through the insertion hole 6 in the limiting ring groove 7, thereby completing the disassembly and fixing of the lid 4 and the box body 3.

[0060] See Figure 1 , Figure 2 , Figure 3 and Figure 4 In this embodiment, when the device is opened, only the lid 4 needs to be picked up and rotated, which can be completed by the operator with one hand, making the operation more convenient.

[0061] See Figure 1 , Figure 2 , Figure 3 and Figure 4 In this embodiment, during winding, the wire passes through the wire hole 5 of the box body 3 and connects to the winding post 9. Then, rotating the handle 10 can drive the winding post 9 to wind the wire. During maintenance, the operator holds the handle 16 of the box cover 4 and rotates it until the first insert hole 11 and the second insert hole 12 of the box cover 4 are aligned with the first limiting piece 13 and the second limiting piece 14, so that the first limiting piece 13 and the second limiting piece 14 are completely disengaged from the limiting ring groove 7. Finally, pulling the box cover 4 outward can complete the separation of the box cover 4 and the box body 3.

[0062] Example 2

[0063] See Figure 1 , Figure 2 , Figure 3 and Figure 4 Based on Embodiment 1, in this embodiment, a V-shaped groove 17 for clamping the end of the wire is provided at one end of the winding post 9 near the cover 4. The V-shaped groove 17 extends along the axial direction of the winding post 9. The V-shaped groove 17 facilitates the squeezing and clamping of the end of the wire, and the wire can be wound up when the winding post 9 rotates.

[0064] The diameter of the middle section of the winding post 9 is smaller than the diameter of the two ends of the winding post 9. This makes the winding post 9 have a small diameter in the middle and a large diameter at both ends, which makes it easier for the wire to be wound on the winding post 9 and makes it less likely for the wire to come off the winding post 9.

[0065] A rubber block 18 is fixedly installed on the side of the handle 10 near the box 3. The side of the rubber block 18 near the box 3 is tightly pressed against the side of the box 3 near the rubber block 18. The rubber block 18 can increase frictional damping and increase the stability of the rotation of the handle 10. When the operator rotates, the rotational force of the handle 10 is greater than the resistance of the rubber block 18. Therefore, the setting of the rubber block 18 does not affect the rotation of the handle 10. When the handle 10 is not rotating, the resistance of the rubber block 18 is greater than the counter-rotation force of the wire wound by the winding post 9, which effectively prevents the wire from loosening after winding.

[0066] The cover 4 has a through hole 19 on its axis. The end of the winding post 9 near the cover 4 is rotatably fitted into the through hole 19. This effectively prevents the wire from coming out of the end of the winding post 9 and also prevents the cover 4 and the winding post 9 from rubbing against each other.

[0067] In this embodiment, during winding, the wire passes through the wire hole 5 of the housing 3 and connects to the V-shaped groove 17 of the winding post 9. Then, rotating the lever 10 can drive the winding post 9 to wind the wire. The rubber block 18 is in contact with the surface of the housing 3 to increase frictional damping and increase the stability of the lever 10 rotation.

[0068] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
