Abstract
Description
Technical Field
[0001] This application relates to the field of accessories and tools in cigarette workshops, and in particular to an electrical protection device. Background Technology
[0002] Cigarette factories require a large number of equipment to work together in their daily production processes. The locations and heights of these equipment vary, so various platforms of a certain height need to be set up in the workshop for people to move around on. In addition, electrical cables are often installed on these platforms to provide power to the equipment. When installing electrical cables, conduits and junction boxes are usually installed, and the cables are run through them to provide a certain degree of protection. However, in actual production, it has been found that since the conduits and junction boxes on the platforms are exposed, people often touch the junction boxes when walking on the platforms, which can easily damage them and pose a certain safety hazard. Utility Model Content
[0003] The purpose of this application is to provide an electrical protection device that can cover and protect junction boxes, thereby effectively solving the shortcomings of the prior art.
[0004] Therefore, this application provides an electrical protection device, including:
[0005] A first housing has an accommodating space and an opening, and the first housing is used to cover a portion of the junction box;

[0007] The opening sides of the first housing and the second housing can be joined together to cover the conduit box, and a predetermined number of sheath tubes are formed after the opening sides of the first housing and the second housing are joined together. The sheath tubes are used to cover the outside of the conduit tube.
[0008] In some possible implementations, both the first and second housings are cylindrical structures with a square cross-section and an open end.
[0009] In some possible implementations, both the first and second housings are cylindrical structures with a square cross-section and an open end.
[0010] In some possible implementations, the first housing has a first half-sleeve on its open side and the second housing has a second half-sleeve on its open side. When the open sides of the first housing and the second housing are joined together, the first half-sleeve and the second half-sleeve are joined together to form a sheath tube.
[0011] In some possible implementations, the sheath tube is a cylindrical structure.
[0012] In some possible implementations, the cross-sections of the first half-set and the second half-set are both semi-circular.
[0013] In some possible implementations, the opening side of the first housing and the opening side of the second housing are joined to form a square cross-section, and on each of the four outer peripheral sides of the square cross-section, there are multiple sheath tubes.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0022] like Figures 1-3 As shown, this application provides an electrical protection device applied in cigarette factory workshops, particularly in the electrical systems of cigarette factories. Cigarette factories have numerous production equipment with varying locations and heights, necessitating the installation of platforms at certain heights for workers to access and for powering various devices. These platforms often house electrical cables. To protect these cables, conduits and junction boxes are typically laid exposed on the platform, with cables running through them. Frequent movement of workers on the platform leads to frequent contact with the junction boxes, potentially causing damage. Severe damage to the junction boxes exposes cables, posing a safety hazard. This application's electrical protection device aims to protect the junction boxes, preventing damage and improving the safety of the electrical circuits.
[0023] The electrical protection device includes a first housing 100 and a second housing 200. The first housing 100 has an accommodating space and an opening, and is used to cover a portion of the junction box. The second housing 200 also has an accommodating space and an opening, and is used to cover a portion of the junction box. Both the first housing 100 and the second housing 200 are shell-shaped, have internal accommodating spaces, and both have openings. The first housing 100 is used to cover the outer side of a portion of the junction box, and the second housing 200 is used to cover the remaining portion of the junction box. The first housing 100 and the second housing 200 cooperate to cover the junction box. Both the first housing 100 and the second housing 200 have an opening on one side, and both cover the outer side of the junction box. The opening side of the first housing 100 and the opening side of the second housing 200 are joined together to cover the wiring box. This effectively protects the wiring box from collision damage, improving the safety of the electrical system. Furthermore, the joining of the opening sides of the first housing 100 and the second housing 200 forms a protective sleeve. A predetermined number of these protective sleeves are used to cover the outside of the wiring tubes. In this embodiment, the number of protective sleeves is not less than the number of wiring tubes connected to the protected wiring box. The protective sleeves cover a portion of the wiring tube connected to the wiring box. On one hand, the protective sleeves provide clearance to smoothly cover the wiring box connected to the wiring tubes. On the other hand, the protective sleeves and wiring tubes form a sleeve structure, mutually limiting each other, which helps improve the stability of the connection between the first housing 100, the second housing 200, and the wiring box, enhancing the overall structural strength.
[0024] Preferably, both the first outer shell 100 and the second outer shell 200 are cylindrical structures with a square cross-section and an open end. Both the first outer shell 100 and the second outer shell 200 are long cylindrical structures, preferably long cylindrical structures with a square cross-section. More preferably, both the first outer shell 100 and the second outer shell 200 are long cylindrical structures with an open end and a closed end.
[0025] In one example, both the first outer shell 100 and the second outer shell 200 are cylindrical structures with square cross-sections and open at one end. That is, the first outer shell 100 is a long cylindrical structure with a square cross-section, and the second outer shell 200 is a long cylindrical structure with a square cross-section. The first outer shell 100 is open at one end and closed at the other end, and the second outer shell 200 is open at one end and closed at the other end. In this way, the open end of the first outer shell 100 can be connected to the open end of the second outer shell 200, and the internal space formed after the connection is used to accommodate the wiring box.
[0026] More preferably, a first half-sleeve 101 is provided on the open side of the first outer shell 100, and a second half-sleeve 202 is provided on the open side of the second outer shell 200. When the open sides of the first outer shell 100 and the second outer shell 200 are joined, the first half-sleeve 101 and the second half-sleeve 202 are joined to form a protective sleeve. In this embodiment, the first outer shell 100 is a square cross-section cylindrical structure with one end open and the other end closed, and the second outer shell 200 is a square cross-section cylindrical structure with one end open and the other end closed. After the open ends of the first outer shell 100 and the second outer shell 200 are joined, the resulting internal cavity is used to accommodate the wiring box. After the first outer shell 100 and the second outer shell 200 are joined, they completely cover the outside of the wiring box, thereby providing protection for the wiring box. Preferably, the first outer shell 100 and the second outer shell 200 are both made of metal to further enhance the protective effect on the wiring box. In this embodiment, the first outer shell 100... A first half-set 101 is provided on the outer periphery of one end of the opening of the first outer shell 100, and a second half-set 202 is provided on the outer periphery of one end of the opening of the second outer shell 200. When the opening ends of the first outer shell 100 and the second outer shell 200 are connected, the first half-set 101 and the second half-set 202 are also connected, forming a cylindrical sheath. This sheath is used to cover the outside of the conduit. In practice, when installing it on the conduit box, the first outer shell 100 can be first placed on a part of the outside of the conduit box, so that the first half-set 101 is also attached to a part of the outside of the conduit on the conduit box. Then, the second outer shell 200 is placed on the remaining part of the conduit box, so that the first outer shell 100 and the second outer shell 200 are connected and completely cover the outside of the conduit box. The first half-set 101 and the second half-set 202 are also connected and cover the part of the outside of the end of the conduit connected to the conduit box. In this way, the protection of the conduit box is completed.
[0027] Preferably, the sheath tube has a cylindrical structure. In this embodiment, the cross-sections of the first half-sleeve 101 and the second half-sleeve 202 are both semi-annular, and the first half-sleeve 101 and the second half-sleeve 202 form a symmetrical structure. The first half-sleeve 101 and the second half-sleeve 202 are symmetrical with respect to the plane passing through the axis of the sheath tube. The cross-sections of the first half-sleeve 101 and the second half-sleeve 202 are both semi-annular, so that the first half-sleeve 101 and the second half-sleeve 202 both form an open structure, which facilitates cooperation with the conduit.
[0028] In this embodiment, the opening side of the first outer shell 100 and the opening side of the second outer shell 200 are joined to form a square cross-section. On the four outer peripheral sides of the square cross-section, there are multiple sheaths on each outer peripheral side. That is, the first outer shell 100 and the second outer shell are both square cross-section cylindrical structures with one end open and the other end closed. After the opening end of the first outer shell 100 and the opening end of the second outer shell 200 are joined, they form an integral square cross-section, forming four outer peripheral sides along the circumference. The integral sheaths are located on the outer peripheral sides, and there are multiple sheaths on each outer peripheral side. In other words, for the first outer shell 100, four sides are also formed in the circumference. The first half-set 101 is disposed on the side of the first outer shell 100. The second outer shell 200 also forms four sides in the circumference. The second half-set 202 is disposed on the side of the second outer shell 200.
[0029] The opening side of the first outer shell 100 and the opening side of the second outer shell 200 are joined to form a square cross-section. On the four outer peripheral sides of the square cross-section, the number of sheath tubes on each outer peripheral side is multiple and equal.
[0030] Preferably, the opening sides of the first outer casing 100 and the second outer casing 200 are joined to form a square cross-section. On each of the four outer peripheral sides of this square cross-section, there are two sheaths. This is because, in practice, two connection holes are provided on each side of the junction box along the circumferential direction to connect with the conduit at two locations. The specific location of the connection hole for the conduit is uncertain and can only be determined based on the actual space requirements on site. Therefore, two sheaths are formed on each outer peripheral side of the square cross-section to ensure… The conduit can form a fitted retaining structure with the conduit, improving the overall structural strength. Specifically, after the first outer shell 100 and the second outer shell 200 are joined, they form a square cross-section. The number of sheaths on each of the four circumferential sides of the square cross-section is two. That is, for the first outer shell 100, two first half-sleeves 101 are provided on each of the four circumferential sides. The first half-sleeve 101 is located near the periphery of the opening end of the first outer shell 100. Both the first half-sleeve 101 and the second half-sleeve 202 are semi-annular arc-shaped plate structures. The axis of the first half-sleeve 101 is perpendicular to the first outer shell. The first half-set 101 of the first housing 100 is located on the side of the first housing 100, and the arc-shaped opening of the first half-set 101 faces the same direction as the opening of the first housing 100. Similarly, two second half-sets 202 are provided on each of the four circumferential sides of the second housing 200. The second half-set 202 is located near the periphery of the opening end of the second housing 200, and the axis of the second half-set 202 is perpendicular to the side of the second housing 200 where the second half-set 202 is located. The arc-shaped opening of the second half-set 202 faces the same direction as the opening of the second housing 200, which facilitates the connection and coverage of the junction box and the localization of the conduit. The first outer shell 100 is provided with a notch 30 at the position corresponding to the first half 101, so that the internal arc-shaped cavity of the first half 101 is connected to the internal space of the first outer shell 100. The second outer shell 200 is provided with a notch 30 at the position corresponding to the second half 202, so that the internal arc-shaped cavity of the second half 202 is connected to the internal space of the second outer shell 200. That is, so that the internal space of the overall structure formed by the first outer shell 100 and the second outer shell 200 after docking is connected to the sheath tube, so as to form an overall cover for the part of the wiring box and the wiring tube.
[0031] The first outer casing 100 has an outwardly flared base 103 on the side opposite to the opening. The first outer casing 100 is open at one end and closed at the other end. The base 103 is located at the closed end of the first outer casing 100, forming an outwardly flared, large-foot-shaped structure. In actual installation, the first outer casing 100 is fitted onto the bottom part of the wiring box, so that the base 103 of the first outer casing 100 rests on the platform plane. Then, the second outer casing 200 is placed over the top part of the wiring box to form a mating enclosure, which helps to improve the overall stability on the platform.
[0032] The first outer shell 100 and the second outer shell 200 can be connected by screws or adhesive. When using screw connection, the screw passes through the second outer shell 200 and is screwed into the first outer shell 100. The screw passes through the side wall of the second outer shell 200 and is screwed into the side wall of the first outer shell 100. The length direction of the screw is parallel to the opening direction of the first outer shell 100.
