Description

Technical Field

[0001] This utility model relates to the field of cable shaft technology, specifically a modular fireproof cable shaft. Background Technology

[0002] Modular fireproof cable shafts are vertical channel systems specifically designed for cable cabling. They combine modular assembly and fireproof features to improve the safety, construction efficiency, and ease of maintenance of building electrical systems.

[0003] Some existing cable shafts are vertical, requiring workers to use tools when repairing higher sections of the shaft. However, these shafts often lack designated tool storage areas, forcing workers to carry tools on their bodies, increasing their weight and making operations inconvenient. To address these issues, we offer modular fire-resistant cable shafts. Utility Model Content

[0009] An mounting plate is connected to the outer surface of the heat-insulating shell, and a sealing plate is connected to the inside of the mounting plate.

[0010] Furthermore, a spring is connected inside the support shell, and the end of the spring away from the support shell is connected to the upper surface of the extension plate.

[0011] Furthermore, the extension plate is internally connected to a limiting rod, and a sleeve is slidably connected to the outer surface of the limiting rod. The upper surface of the sleeve is connected to the interior of the support shell.

[0012] Furthermore, the bottom surface of the foot pad contacts the upper surface of the baffle, and the outer surface of the foot pad is slidably connected to the outer surface of the shaft body.

[0015] Furthermore, the sleeve has a vent hole inside, and the outer surface of the extension plate is slidably connected to the outer surface of the sleeve.

[0016] Furthermore, the spring is sleeved on the outer surface of the sleeve, and the outer surface of the sealing plate is in contact with the outer surface of the heat-insulating shell.

[0017] Beneficial effects:

[0018] Compared with existing technologies, this modular fireproof cable shaft has the following advantages:

[0019] I. This modular fireproof cable shaft, through the cooperation of components such as foot pads and barrier plates, allows workers to place items on the foot pads, providing a place for them to step on in special circumstances. The barrier plates cover the foot pads, preventing items from easily falling off. This provides workers with a place to place items, eliminating the need to carry them all the time and solving the problem of carrying many or heavy tools affecting operation.

[0020] Second, this modular fireproof cable shaft, through the cooperation of components such as horizontal plates and sleeves, allows the horizontal plates to restrict the position of the adjusting blocks, thus preventing them from shaking during use. When a user steps on the foot pad in an emergency, outside air will enter the sleeve through the ventilation holes as the foot pad descends. By slowing down the air intake, the foot pad can descend slowly, thus preventing the foot pad from suddenly and rapidly descending and startling the staff when they step on it. This is very convenient. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0030] like Figure 1-6As shown, this utility model provides a technical solution: a modular fireproof cable shaft, including a shaft body 1, a low thermal conductivity rod 2 connected inside the shaft body 1, a baffle 3 connected to the outer surface of the shaft body 1, a heat-insulating shell 4 connected to one end of the low thermal conductivity rod 2, an adjusting block 5 rotatably connected to the outer surface of the low thermal conductivity rod 2, a fireproof coating on the outer surface of the shaft body 1, the shaft body 1 fixing the position of the low thermal conductivity rod 2, the low thermal conductivity rod 2 having low thermal conductivity, the shaft body 1 restricting the position of the baffle 3, the outer surface of the heat-insulating shell 4 being coated with a heat-insulating coating, and the heat-insulating shell 4 being made of a material with low thermal conductivity, the adjusting block 5 changing its orientation by rotating around the low thermal conductivity rod 2.

[0031] The bottom surface of the adjusting block 5 is connected to the support shell 6. The low heat conduction rod 2 is internally engaged with the limiting plate 7. The outer surface of the limiting plate 7 is connected to the horizontal plate 8. The inside of the support shell 6 is slidably connected to the extension plate 9. The outer surface of the extension plate 9 is connected to the foot pad 10. The outer surface of the foot pad 10 is connected to the barrier plate 11. When the adjusting block 5 moves, it will move the support shell 6. The low heat conduction rod 2 can prevent the limiting plate 7 from rotating. When the limiting plate 7 moves, it will move the horizontal plate 8. The support shell 6 will restrict the direction in which the extension plate 9 can move. When the extension plate 9 moves, it will move the foot pad 10. The barrier plate 11 will block the area around the foot pad 10.

[0032] The outer surface of the heat-insulating shell 4 is connected to the mounting plate 12, and the interior of the mounting plate 12 is connected to the sealing plate 13. When the two shaft bodies 1 are connected to each other, the sealing plate 13 will block the outside of the contact gap of the heat-insulating shell 4 inside the two shaft bodies 1 to better seal the device. The surfaces of the mounting plate 12 and the sealing plate 13 are both provided with heat-insulating coatings to prevent high temperature damage to the cable caused by external fire.

[0033] A spring 14 is connected inside the support shell 6. The end of the spring 14 away from the support shell 6 is connected to the upper surface of the extension plate 9. The support shell 6 restricts the position of the spring 14, and the spring 14 provides tension to the extension plate 9.

[0034] The extension plate 9 is internally connected to a limiting rod 15. A sleeve 16 is slidably connected to the outer surface of the limiting rod 15. The upper surface of the sleeve 16 is connected to the inside of the support shell 6. When the extension plate 9 moves, it will move the limiting rod 15 along with it, allowing the limiting rod 15 to be inserted into the sleeve 16. The support shell 6 will restrict the position of the sleeve 16.

[0035] The bottom surface of the foot pad 10 contacts the upper surface of the baffle 3, and the outer surface of the foot pad 10 is slidably connected to the outer surface of the shaft body 1. The baffle 3 restricts the position where the foot pad 10 can move.

[0036] The upper surface of the horizontal plate 8 is slidably connected to the bottom surface of the adjusting block 5, and the outer surface of the horizontal plate 8 is slidably connected to the outer surface of the support shell 6. The position of the adjusting block 5 is restricted by the horizontal plate 8 and the limiting plate 7, so that the adjusting block 5 cannot rotate at will.

[0037] A flange 17 is installed on the outer surface of the shaft body 1. The outer surface of the baffle plate 11 is slidably connected to the outer surface of the support shell 6. The two shaft bodies 1 are connected by the flange 17. The support shell 6 restricts the direction in which the baffle plate 11 can move.

[0038] The sleeve 16 has a vent hole 18 inside. The outer surface of the extension plate 9 is slidably connected to the outer surface of the sleeve 16. When the limiting rod 15 is pulled out of the sleeve 16, outside air will enter the sleeve 16 through the vent hole 18. However, the vent hole 18 is small, and the efficiency of outside air entering the vent hole 18 is low, thus limiting the speed at which the limiting rod 15 is pulled out of the sleeve 16.

[0039] Spring 14 is fitted on the outer surface of sleeve 16, and the outer surface of sealing plate 13 is in contact with the outer surface of heat-insulating shell 4. Sleeve 16 can prevent spring 14 from bulging to one side when compressed.

[0040] Working principle: When using, first pull out the limiting plate 7, then rotate the adjusting block 5 to the position where the support shell 6 is perpendicular to the flange 17, then reinsert the limiting plate 7, let the horizontal plate 8 block the adjusting block 5, pull down the foot pad 10, the foot pad 10 moves and causes the limiting rod 15 to be pulled out from the sleeve 16, then the user can put all the tools on the foot pad 10, then the spring 14 will pull the extension plate 9, let the extension plate 9 move into the support shell 6, and the support shell 6 and the foot pad 10 will clamp these parts, thereby restricting the position of these parts.

[0041] In the description of this utility model, it should be understood that the terms "left", "right", "up", "down", "top", "bottom", "front", "back", "inner", "outer", "back", "middle", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0042] However, the above description is only a specific embodiment of this utility model and should not be construed as limiting the scope of implementation of this utility model. Therefore, any substitution of equivalent components or equivalent changes and modifications made in accordance with the scope of protection of this utility model should still fall within the scope of the claims of this utility model.
