Description

Technical Field

[0001] This utility model relates to a wire protection device, and more particularly to a wire protection device for electrical automation equipment, belonging to the field of electrical automation wire protection technology. Background Technology

[0002] In electrical automation, the control of large machinery requires a separate control cabinet, and the two are electrically connected by wires with protective sleeves. As a key component of the power system, the performance of the protective sleeve directly affects the reliability and safety of the power equipment. Traditional protective sleeve materials are mostly alloy steel, which has good mechanical strength, but is prone to corrosion and rust under complex environmental conditions, affecting the normal operation of the equipment. In recent years, with the increasing complexity of power systems, the demand for protective sleeves has become more diversified.

[0003] Chinese patent application (CN202323654481.1) discloses an electrical automation wire protection device. The rigid protective tube of this application can be pried open and clamped onto the outside of the electrical automation wire. The rigid protective tubes are connected and extended by the insert plate at the bushing. At the same time, there is a force-bearing buffer block outside the rigid protective tube. However, when using this application, it is not convenient to install the wire, which requires the wire to pass through the rigid protective tube. It is not convenient to protect the connected wire. It is not quick to assemble the wire protection device with the wire. Moreover, after the wire protection device is installed, it lacks a fixing measure with the wire. The wire is prone to partial exposure due to the sliding of the wire protection device, which affects the protection effect.

[0004] To address the aforementioned technical problems, a line protection device for electrical automation equipment is proposed. Utility Model Content

[0005] In view of this, the present invention provides a wire protection device for electrical automation equipment to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial option.

[0006] The technical solution of this utility model is as follows: a wire protection device for electrical automation equipment, including an anti-wear rubber sleeve and a locking mechanism;

[0007] The wear-resistant rubber sleeve has placement grooves evenly distributed on its outer side, and a slanted sliding groove is formed on the side of the wear-resistant rubber sleeve near the placement groove. A retaining groove is formed on the side of the wear-resistant rubber sleeve near the slanted sliding groove. Both the retaining groove and the placement groove are connected to the slanted sliding groove. An insertion port is integrally formed on one side of the wear-resistant rubber sleeve.

[0008] The locking mechanism includes a compression ring and a support pad. The compression ring is equidistantly distributed and sleeved in the placement groove of the anti-wear rubber sleeve. The support pad is equidistantly distributed and fixedly connected to the inside of the anti-wear rubber sleeve. An opening is provided on one side of the compression ring.

[0009] More preferably, the wear-resistant rubber sleeve is fixedly connected with inner support plates that are equidistantly distributed inside.

[0010] More preferably, the anti-wear rubber sleeve has heat dissipation holes evenly distributed inside, and a woven mesh is fixedly connected inside the heat dissipation holes.

[0011] A further preferred embodiment has a limiting block fixedly connected to one side of the card slot.

[0012] More preferably, brackets are symmetrically fixedly connected to the opening of the compression ring.

[0013] More preferably, a rubber pad is fixedly connected to the bottom of the bracket, and a fixing hole is provided inside the bracket.

[0014] The present invention has the following advantages due to the adoption of the above technical solution:

[0015] I. This utility model uses an anti-wear rubber sleeve with an insertion port to cover and protect the wire, making it easy to quickly insert the wire into the anti-wear rubber sleeve through the insertion port. By moving the compression ring, the compression ring squeezes the side of the anti-wear rubber sleeve with the support pad, causing the anti-wear rubber sleeve and the support pad to shrink and fit tightly against the wire. This provides multi-point fixation of the anti-wear rubber sleeve and the wire, preventing the wire from coming out and preventing the anti-wear rubber sleeve from sliding and causing the wire to be partially exposed.

[0016] II. This utility model has an internal support plate inside the anti-wear rubber sleeve to ensure the overall shape of the anti-wear rubber sleeve. The support pad contacts the wire, leaving a certain gap between the anti-wear rubber sleeve and the wire. Combined with heat dissipation holes, it facilitates heat dissipation of the wire.

[0017] The above overview is for illustrative purposes only and is not intended to be limiting in any way. In addition to the illustrative aspects, embodiments, and features described above, further aspects, embodiments, and features of the present invention will become readily apparent from the accompanying drawings and the following detailed description.

[0025] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0026] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0027] like Figure 1-5 As shown, this utility model embodiment provides a wire protection device for electrical automation equipment, which consists of an anti-wear rubber sleeve 11 and a locking mechanism 20.

[0028] The outer side of the anti-wear rubber sleeve 11 is provided with placement grooves 14 evenly distributed. The side of the anti-wear rubber sleeve 11 near the placement grooves 14 is provided with a slanted sliding groove 12. The side of the anti-wear rubber sleeve 11 near the slanted sliding groove 12 is provided with a locking groove 13. Both the locking groove 13 and the placement grooves 14 are connected to the slanted sliding groove 12. One side of the anti-wear rubber sleeve 11 is integrally formed with an insertion port 16. The wire is inserted into the anti-wear rubber sleeve 11 through the insertion port 16.

[0029] In one embodiment, in order to facilitate heat dissipation of the wires, heat dissipation holes 17 are evenly distributed inside the anti-wear rubber sleeve 11, and a braided mesh 18 is fixedly connected inside the heat dissipation holes 17.

[0030] In one embodiment, in order to prevent the anti-wear rubber sleeve 11 from collapsing, the anti-wear rubber sleeve 11 is fixedly connected with inner support plates 15 at equal intervals inside to ensure the overall shape of the anti-wear rubber sleeve 11. The side of the anti-wear rubber sleeve 11 with the support pad 22 is not provided with the inner support plate 15, so that the side with the support pad 22 can undergo a larger degree of shrinkage and deformation.

[0031] The locking mechanism 20 includes a compression ring 21 and a support pad 22. The compression ring 21 is equidistantly distributed and sleeved in the placement groove 14 of the anti-wear rubber sleeve 11. The support pad 22 is equidistantly distributed and fixedly connected to the inside of the anti-wear rubber sleeve 11. An opening 26 is provided on one side of the compression ring 21.

[0032] In one embodiment, a limiting block 19 is fixedly connected to one side of the inner side of the slot 13. The size of the limiting block 19 matches the opening 26 of the extrusion ring 21, so as to limit the rotation of the extrusion ring 21 after it enters the slot 13.

[0033] In one embodiment, a bracket 23 is symmetrically fixedly connected to the opening 26 of the compression ring 21, and a rubber pad 25 is fixedly connected to the bottom of the bracket 23. A fixing hole 24 is provided inside the bracket 23. The bracket 23 and the fixing hole 24 are used to fix the position. The anti-wear rubber sleeve 11 and the wire are supported by the compression ring 21 and the bracket 23.

[0034] In operation, the present invention works as follows: The compression ring 21 is rotated so that its opening 26 aligns with the insertion port 16 of the anti-wear rubber sleeve 11. The wire is inserted into the anti-wear rubber sleeve 11 through the insertion port 16, and the anti-wear rubber sleeve 11 covers the wire. The compression ring 21 is then rotated so that its opening 26 is coaxial with the limiting block 19. The compression ring 21 is slid towards the slot 13, allowing it to slide from the placement slot 14 into the inclined slide groove 12, and then into the slot 13. At this time, the limiting block 19 engages with the opening 26 of the compression ring 21. During the movement of the compression ring 21, the anti-wear rubber sleeve 11 is compressed, causing the anti-wear rubber sleeve 11 to drive the support pad 22 to contract inward, locking the internal wire and thus fixing the wire and the anti-wear rubber sleeve 11. The wire is supported by the support pad 22, leaving a certain gap between it and the anti-wear rubber sleeve 11, allowing heat to be discharged through the heat dissipation hole 17.

[0035] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
