Description

Technical Field

[0001] This utility model relates to the field of fireproof insulation technology, and in particular to a fireproof insulation busbar trunking. Background Technology

[0002] In industrial plants, large-scale building construction, equipment maintenance and other scenarios, busbar trunking, as an efficient power transmission system, is frequently used in conjunction with temporary power distribution boxes to provide temporary power supply for local areas, such as temporary lighting, power for equipment maintenance, power supply for new loads, etc.

[0003] Some temporary power boxes are directly fixed to the busbar support with bolts. This requires many on-site operations during installation, and the bolts are prone to loosening over time, causing the power box to shift, resulting in poor contact between the power contacts and the busbar conductors. In severe cases, this can lead to localized overheating, burning of the contacts, or even power outage. In contrast, simple clip-on fastening has limited clamping force and cannot provide sufficient locking force. When the power box is heavy or subjected to external pulling, the clips are prone to deformation or detachment, which can not only damage the equipment but also cause safety accidents such as electric shock and short circuits. Utility Model Content

[0004] The purpose of this utility model is to solve the problems of cumbersome installation and operation of temporary power supply boxes and the insecure fastening of simple buckles in the existing technology, and to provide a fireproof and insulated busbar trunking.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a fireproof and insulated busbar trunking, comprising a busbar trunking body, an external power extraction hole on the outer surface of the busbar trunking body, an external power extraction contact engaged with the inner wall of the external power extraction hole, a temporary power extraction box fixedly connected to the outer surface of the external power extraction contact, an L-shaped plate fixedly connected to the outer surface of the temporary power extraction box, a fixing member engaged with the outer surface of the L-shaped plate, a first connecting member fixedly connected to one side of the fixing member, a clamping arm rotatably connected to the inner wall of the first connecting member, a second connecting member fixedly connected to the other side of the fixing member, a clamping member rotatably connected to the inner wall of the second connecting member, a third connecting member rotatably connected to the inner wall of the clamping arm, a lead screw fixedly connected to the outer surface of the third connecting member, a handle threadedly connected to the outer surface of the lead screw, and an insulating plate fixedly connected to the outer surface of the temporary power extraction box.

[0006] In a preferred embodiment, a positioning hole is provided on the outer surface of the busbar trunking body, and a positioning element is engaged with the inner wall of the positioning hole.

[0007] In a preferred embodiment, the outer surface of the positioning member is fixedly connected to the outer surface of the temporary power supply box.

[0008] In a preferred embodiment, the outer surface of the lead screw is slidably connected to the inner wall of the clamping member.

[0009] In a preferred embodiment, the outer surface of the clamping member is rotatably connected to the outer surface of the fixing member.

[0010] In a preferred embodiment, the outer surface of the handle is rotatably connected to the inner wall of the clamping member.

[0011] In a preferred embodiment, the outer surface of the lead screw is rotatably connected to the outer surface of the clamping arm, and the outer surface of the clamping arm is rotatably connected to the outer surface of the fixing member.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] This invention utilizes a handle-driven lead screw transmission to clamp the L-shaped plate from both sides. The resulting clamping force, through the self-locking properties of the threads, maintains a superior anti-loosening effect compared to traditional bolts. Even under external forces such as equipment vibration or accidental contact, the power box remains securely fixed. Furthermore, the fault-tolerant guiding function of the positioning structure, especially the rounded corner design of the positioning holes, allows non-professionals to quickly pre-position the power box. Subsequent clamping operations only require rotating the handle to achieve rigid fixation, eliminating the need for complex steps such as finding holes and inserting bolts on-site. This significantly lowers the installation threshold and reduces the labor and time costs of on-site construction or maintenance. Attached Figure Description

[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] Example 1

[0024] like Figures 1-6 As shown, this utility model provides a technical solution: a fireproof and insulated busbar trunking, including a busbar trunking body 1. A power extraction hole 15 is provided on the outer surface of the busbar trunking body 15. A power extraction contact 6 is engaged with the inner wall of the power extraction hole 15. A temporary power extraction box 2 is fixedly connected to the outer surface of the power extraction contact 6. An L-shaped plate 4 is fixedly connected to the outer surface of the temporary power extraction box 2. A fixing member 3 is engaged with the outer surface of the L-shaped plate 4. A first connecting member 8 is fixedly connected to one side of the fixing member 3. A clamping arm 9 is rotatably connected to the inner wall of the first connecting member 8. A second connecting member 12 is fixedly connected to the other side of the fixing member 3. A clamping member 11 is rotatably connected to the inner wall of the clamping arm 9. A third connecting member 10 is rotatably connected to the inner wall of the clamping arm 9. A lead screw 14 is fixedly connected to the outer surface of the third connecting member 10. The outer surface of the lead screw 14 is rotatably connected to the outer surface of the clamping arm 9. The outer surface of the clamping arm 9 is rotatably connected to the outer surface of the fixing member 3. A handle 13 is threadedly connected to the outer surface of the lead screw 14. The outer surface of the handle 13 is rotatably connected to the inner wall of the clamping member 11. The outer surface of the lead screw 14 is slidably connected to the inner wall of the clamping member 11. The outer surface of the clamping member 11 is rotatably connected to the outer surface of the fixing member 3. An insulating plate 7 is fixedly connected to the outer surface of the temporary power supply box 2.

[0025] In this embodiment, a power-taking contact 6 is designed and fixedly connected to a temporary power-taking box 2. An insulating plate 7 is fixedly connected to the temporary power-taking box 2 to facilitate the separation of the contacts and to provide insulation by utilizing its own insulating properties. A power-taking hole 15 is opened on the inner wall of the busbar trunking body 1 to facilitate the insertion of the power-taking contact 6. An L-shaped plate 4 is fixed to the outer surface of the temporary power-taking box 2 and snaps into the inner wall of the fixing member 3. A first connecting member 8 is fixedly connected to one side of the fixing member 3, and a clamping arm 9 is rotatably connected to the inner wall of the first connecting member 8. A third connecting member 10 is rotatably connected to the other side of the clamping arm 9 to facilitate the fixed connection of the lead screw 14 to the clamping arm 9. A thread is opened at the other end of the lead screw 14, and a thread is opened on the inner wall of the handle 13 to facilitate the threaded connection to the end of the lead screw 14. By rotating the handle 13, the distance of the lead screw 14 decreases, and the threaded transmission converts the rotational motion into the lead screw 14 moving towards the end. Moving the handle 13 closer to the center causes the distance between the lead screw 14 and the clamping arm 9 to gradually decrease. The clamping arm 9 is pulled by the third connector 10 and rotates around the first connector 8, gradually fitting and tightly clamping onto the outer surface of the L-shaped plate 4. The slot of the clamping arm 9 is firmly clamped onto the outer surface of the L-shaped plate 4. At this time, the clamping member 11 rotates around the second connector 12, and the protrusion of the clamping member 11 simultaneously clamps the other side of the L-shaped plate 4. Under the combined action of the L-shaped plate 4 and the clamping member 11, the outer surface of the L-shaped plate 4 rubs against the inner wall of the fixing member 3. When the slot of the clamping arm 9 and the protrusion of the clamping member 11 press the L-shaped plate 4 together from both sides, a huge static friction force is generated between the outer surface of the L-shaped plate 4 and the inner wall of the fixing member 3. The clamping force of the clamping arm 9 and the clamping member 11 on the L-shaped plate 4, together with the static friction force, completely locks the displacement of the L-shaped plate 4, and finally makes the temporary power supply box 2 and the fixing member 3 rigidly fixed and unable to loosen.

[0026] Example 2

[0027] like Figures 1-6 As shown, a positioning hole 16 is provided on the outer surface of the busbar trunking body 1, and a positioning component 5 is engaged with the inner wall of the positioning hole 16. The outer surface of the positioning component 5 is fixedly connected to the outer surface of the temporary power supply box 2.

[0028] In this embodiment, the positioning hole 16 opened on the surface of the busbar trunking body 1, with the rounded corners of the positioning hole 16, facilitates the accurate insertion of the power contact 6 on the temporary power supply box 2 into the power supply hole 15 with the cooperation of the positioning member 5. This allows the temporary power supply box 2 to move along a preset trajectory, avoiding misalignment of the power contact 6 and the power supply hole 15 due to offset during installation. When the positioning member 5 is fully inserted into the positioning hole 16, it not only provides a reference for aligning the power contact 6 with the power supply hole 15, but also forms a double positioning with the clamping structure of the L-shaped plate 4 and the fixing member 3. The positioning member 5 limits the translational deviation of the temporary power supply box 2 in the horizontal and vertical directions, while the clamping structure fixes its overall position. The two work together to ensure that the power contact 6 will not wobble slightly due to external force after being inserted into the power supply hole 15, thus ensuring the stability of the electrical contact.

[0029] Working principle:

[0030] like Figure 1 As shown in the figure, when temporary power is needed, the temporary power box 2 is first inserted into the positioning hole 16 through the positioning piece 5, forcing the temporary power box 2 to move along the preset trajectory, ensuring that the power contact 6 and the power hole 15 are precisely aligned. The L-shaped plate 4 on the outer surface of the temporary power box 2 is first engaged with the inner wall of the fixing piece 3. At this time, the temporary power box 2 is in a preliminary positioning but not locked state, preparing for subsequent clamping. By rotating the handle 13, the distance of the lead screw 14 decreases, and the threaded transmission will convert the rotational motion into the lead screw 14 moving towards the handle 13, so that the distance between the lead screw 14 and the clamping arm 9 gradually decreases. The clamping arm 9 is pulled by the third connecting piece 10, at which time the... The movable clamping member 11 rotates around the second connecting member 12, while the protrusion of the clamping member 11 firmly clamps the other side of the L-shaped plate 4. Under the combined action of the L-shaped plate 4 and the clamping member 11, the outer surface of the L-shaped plate 4 rubs against the inner wall of the fixing member 3. When the slot of the clamping arm 9 and the protrusion of the clamping member 11 press the L-shaped plate 4 together from both sides, a huge static friction force is generated between the outer surface of the L-shaped plate 4 and the inner wall of the fixing member 3. The clamping force of the clamping arm 9 and the clamping member 11 on the L-shaped plate 4 and the static friction force work together to completely lock the displacement of the L-shaped plate 4, and finally make the temporary power supply box 2 and the fixing member 3 rigidly fixed and unable to loosen, so as to realize the safe transmission of current.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
