Description

Technical Field

[0001] This utility model relates to the field of threading box technology, and in particular to a chain-type threading box with an anti-detachment cover. Background Technology

[0002] A junction box, also known as a junction box, is a basic component in an industrial electrical wiring system used to protect and house the connections of wires and cables. Its core function is to provide a closed, accessible operating space to ensure the electrical safety, mechanical protection, and environmental isolation of the wire connection points.

[0003] In existing technologies, when operators open the cover for maintenance or other work, they may inadvertently fail to place the cover in the correct position, resulting in the cover being lost. This exposes the entire wiring cavity of the junction box, causing the explosion-proof performance to fail. Searching for or reinstalling the cover will prolong equipment downtime. Although some junction boxes have added connection structures to prevent the cover from being lost, the connectors of these connection structures are relatively complex, occupy a lot of space, and there is no pre-reserved installation position on the junction box.

[0004] Therefore, there is a need for a convenient cable management box with an anti-loss lid.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the general background of this disclosure and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0007] This utility model provides an anti-detachment chain-type cable box, comprising: The wire-passing box has a hollow interior forming a wire-passing cavity. The wire-passing box is provided with several wire-passing ports, and the wire-passing ports are connected to the wire-passing cavity. An operation window is provided on one side of the wire-passing box. An installation point is provided on the wire-passing box, and a first installation hole is provided on the installation point. The cover is fixedly installed on the wiring box body corresponding to the operation window, and a second mounting hole is provided on the cover; The anti-detachment chain is fixedly installed at one end in the first mounting hole and at the other end in the second mounting hole.

[0008] Furthermore, a rubber pad is provided between the wiring box and the box cover, and the outline of the rubber pad corresponds to the outline of the operation window.

[0009] Furthermore, the box cover has a slot on the side facing the rubber pad, and the rubber pad has a raised strip that engages with the slot.

[0010] Furthermore, the side of the box cover away from the wire-threading box body is recessed inward to form a nameplate groove.

[0011] Furthermore, the wiring box body, the box cover, and the rubber pad are respectively provided with fixing holes, and fixing components are provided in the fixing holes.

[0012] Furthermore, the cross-section of the threading box corresponding to the threading opening is set as an octagon with rounded corners.

[0013] Furthermore, at least two cable ports are provided.

[0014] Furthermore, chain connectors are provided at both ends of the anti-detachment chain, and the chain connectors at both ends are fixedly connected to the first mounting hole and the second mounting hole, respectively.

[0015] Furthermore, the chain connector is in the shape of a thin sheet with a through hole in the middle, corresponding to the first mounting hole or the second mounting hole.

[0016] The following technical effects can be achieved through the technical solution of this utility model: The two ends of the anti-detachment chain are fixed to the cable box body and the cover respectively. Even if all the fasteners are removed during maintenance, the cover remains physically connected to the cable box body.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0022] This utility model provides a method such as Figures 1 to 9 The anti-detachment chain-type cable box shown includes: The wire box 1 has a hollow interior forming a wire passage cavity 11. The wire box 1 is provided with several wire passage openings 12, and the wire passage openings 12 are connected to the wire passage cavity 11. An operation window 13 is provided on one side of the wire box 1. An installation point 14 is provided on the wire box 1, and a first installation hole 141 is opened on the installation point 14. The cover 2, corresponding to the operation window 13, is fixedly installed on the wire-passing box body 1, and a second mounting hole 21 is opened on the cover 2; The anti-detachment chain 3 is fixedly installed at one end in the first mounting hole 141 and at the other end in the second mounting hole 21.

[0023] The junction box includes, for example, Figures 5 to 9 The various specifications and appearances of straight-through, angle, tee, and cross connectors shown are illustrated in this embodiment using a straight-through junction box. (Refer to...) Figures 1 to 5 .

[0024] The junction box 1 is made of cast metal alloy and has a hollow interior forming a conduit 11 for accommodating wire connectors and performing wiring operations. The junction box 1 has at least two cable entry / exit ports 12 for cables to pass through and exit. A large opening, or operating window 13, is provided on the side of the junction box 1, allowing operation of the electrical connections within the conduit 11. The cover 2 is a cover plate corresponding to the shape and size of the operating window 13 and can be made of the same material as the junction box 1.

[0025] The mounting point 14 on the junction box 1 can be a metal lug welded to the outer wall of the junction box 1, or it can be a boss structure integrally cast with the junction box 1, which further enhances the structural strength and simplifies the manufacturing process. A first mounting hole 141 is machined on the mounting point 14; and a second mounting hole 21 is machined on the cover 2, preferably located in the edge area of ​​the cover 2, so as to avoid affecting the integrity of the main structure of the cover 2 and the sealing surface. The first mounting hole 141 and the second mounting hole 21 can be a smooth through hole 32 or a threaded hole.

[0026] The anti-detachment chain 3 can be a standardized metal chain, such as a zigzag chain made of elliptical links or a general chain made of figure-eight links. The length needs to be set so that the cover 2 can be placed stably after it is fully opened without the chain being taut. The two ends of the anti-detachment chain 3 are fixedly connected to the first mounting hole 141 and the second mounting hole 21 respectively. No additional complex connection structure is needed, and no extra space is occupied. The cover 2 is connected to the cable box body 1, which can prevent the cover 2 from being lost, and does not affect the sealing performance and explosion-proof rating of the cable box, thus improving the convenience of cable box maintenance. Moreover, as the specifications and shape of the cable box change, the mounting point 14 and the corresponding first mounting hole 141 can also be changed accordingly to adapt to the appearance of the cable box, making it more flexible to use.

[0027] In some embodiments of this utility model, such as Figure 2 As shown, a rubber pad 4 is provided between the cable box body 1 and the cover 2, and the outline of the rubber pad 4 corresponds to the outline of the operating window 13. The rubber pad 4 is preferably made of a material with excellent elasticity and weather resistance, such as silicone rubber or fluorosilicone rubber. When the cover 2 is fixed on the cable box body 1, the rubber pad 4 is compressed and deformed to fill the gap between the two, thereby effectively isolating the intrusion of external explosive gases, dust, moisture and corrosive media, while preventing the escape of possible internal electric sparks, and meeting the requirements of explosion-proof standards.

[0028] In some embodiments of this utility model, such as Figure 3 and Figure 4 As shown, a groove 22 is provided on the side of the cover 2 facing the rubber pad 4, and a raised strip 41 is provided on the rubber pad 4, which is inserted into the groove 22. When installing the cover 2 and the rubber pad 4, the rubber pad 4 may slide and misalign due to force or improper operation, resulting in partial sealing failure. In this embodiment, by setting the positioning cooperation of the groove 22 and the raised strip 41, during assembly, the raised strip 41 is inserted into the groove 22, forming a temporary assembly of the cover 2 and the rubber pad 4. Then, the entire assembly is aligned with the operating window 13 and finally fixed to the wiring box 1, effectively avoiding the problem of poor sealing caused by the movement of the rubber pad 4.

[0029] The cross-sectional shape of the protruding strip 41 can be semi-circular, rectangular or trapezoidal. In this embodiment, a rectangular cross-section is used for demonstration.

[0030] In some embodiments of this utility model, such as Figure 5 As shown, the side of the cover 2 away from the junction box body 1 is recessed inward to form a nameplate groove 23. This recessed area, formed by machining or directly on the mold of the cover 2, provides a dedicated installation position for the nameplate of the junction box. The outline shape of the nameplate groove 23 can be determined according to the specific nameplate shape, commonly rectangular or oblong. Furthermore, the depth of the nameplate groove 23 matches the thickness of the nameplate, so that after the nameplate is installed, the surface of the cover 2 has no protrusions or depressions, and is a flat and continuous plane. This avoids the disadvantages of the nameplate edge catching debris, accumulating dust and rainwater, and significantly improves the dust-free and self-cleaning ability of the cover 2 surface.

[0031] In some embodiments of this utility model, such as Figure 5 As shown, the cable box body 1, the cover 2, and the rubber pad 4 are respectively provided with fixing holes 15, including the cover 2 fixing hole 15 on the cover 2, the rubber pad 4 fixing hole 15 on the rubber pad 4, and the box body fixing hole 15 on the cable box body 1. The three corresponding fixing holes 15 are used to install fasteners 16. The box body fixing hole 15 can be a threaded hole for engaging with the threaded end of the fastener 16, such as a screw or nut. The cover 2 fixing hole 15 can be a smooth hole with a diameter slightly larger than the diameter of the rod of the fastener 16 to provide a certain centering tolerance; or it can be a threaded hole to further fix the screw. The diameter of the rubber pad 4 fixing hole 15 is slightly smaller than the diameter of the rod of the fastener 16, using the elasticity of the rubber to make it fit tightly with the fastener 16, which helps to enhance the sealing effect; or the diameter can be slightly larger so that the fastener 16 can pass through the fixing hole 15 better.

[0032] In some embodiments of this utility model, such as Figure 1As shown, the cross-section of the junction box 1 corresponding to the cable passage 12 is set as an octagon with rounded corners, eliminating the appearance with sharp edges and corners, which meets the safety requirements of explosion-proof electrical equipment for the absence of sharp edges and corners. In addition, this forms a guide curved surface without a platform or sharp groove on the surface of the cable passage 12. Dust particles falling from the surface of the cable passage 12 structure will be easily guided away from the surface by gravity, wind or daily cleaning, resulting in a dust-free effect.

[0033] In some embodiments of this utility model, such as Figure 5 and Figure 6 As shown, at least two cable entry ports 12 are provided. One cable entry port 12 serves as the cable inlet, and the other serves as the cable outlet, allowing the cable to pass through the cable passage cavity 11 of the junction box to form a continuous electrical path.

[0034] Furthermore, depending on the actual wiring requirements, the number of cable trays 12 can be set to two or more, thus forming different types of cable boxes; when two cable trays 12 are provided, such as Figure 5 As shown, a straight-through type cable box can be constructed located on both sides of the cable-passing cavity 11; or it can be constructed as shown in the figure. Figure 6 The angle-type cable tray shown, positioned on different sides of the cable tray cavity 11, can also have two cable outlets 12 angled and positioned on the same side of the cable tray, such as... Figure 9 As shown, the overall shape is that of a gold ingot; when three cable ports 12 are provided, the three cable ports 12 can be distributed in a T-shape, as shown below. Figure 7 As shown, this implements a three-way branching of the line; when the number of cable entry points 12 increases to four or more, it constitutes a multi-port type junction box, such as a four-port junction box, see reference. Figure 8 The cable ports 12 can be distributed on multiple surfaces of the cable box 1 to form a cabling hub, which enhances the flexibility and complexity of cabling and can connect cables from multiple directions at the same time. It is suitable for nodes that require centralized wiring or complex line control.

[0035] It should be noted that the above-mentioned configurations of different numbers of cable passages 12 can be freely combined with other features of this utility model, such as the cross-sectional shape of the cable passage 12 being an octagonal cross-section with rounded corners, the anti-detachment chain 3, etc. The mounting point 14 and the first mounting hole 141 are also adaptively set on cable boxes of different specifications.

[0036] In some embodiments of this utility model, such as Figure 5As shown, chain connectors 31 are provided at both ends of the anti-detachment chain 3. The chain connectors 31 at both ends are fixedly connected to the first mounting hole 141 and the second mounting hole 21, respectively. The chain connectors 31 provide a reliable connection interface that matches the size and shape of the mounting hole. The firm fixation to the end of the chain does not affect the overall aesthetics and normal operation of the wiring box. It can withstand the weight of the box cover 2 and the mechanical load generated by daily opening and closing and shaking, ensuring that it will not loosen or fail during the equipment's life cycle.

[0037] In some embodiments of this utility model, such as Figure 5 As shown, the chain connector 31 is in the shape of a thin sheet with a through hole 32 in the middle, corresponding to the first mounting hole 141 or the second mounting hole 21. During installation, an independent connecting shaft, such as a rivet, pin or screw, can be used to pass through this through hole 32 and fix both ends of the connecting shaft in the first mounting hole 141 or the second mounting hole 21.

[0038] Of course, the chain connector 31 can also be formed by welding or in-mold forming with a link at the end of the chain to form a connector with a hole at the end, which serves as a thickened or irregularly shaped end link. The through hole 32 in the middle is used to accommodate the connecting shaft mentioned above, eliminating the connection interface between the anti-detachment chain 3 and the chain connector 31, and further improving the overall connection strength and reliability.

[0039] This embodiment constructs a complete and convenient connection method by pre-setting mounting holes on the cable box body 1 and the box cover 2 and matching them with a chain connector 31 with a suitable structure. The structure is compact, sturdy and durable, and solves the problem of preventing the box cover 2 from being lost.

[0040] Based on the above embodiments, you can refer to Figure 1 The number 3 on the cover 2 can also be added to the cover 2, and the number can be matched with the model of the wiring box. This allows the operator to select the required thread size of the wiring box more quickly by using the number marked on the cover 2 during on-site construction, making the work more convenient.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
