Description

Technical Field

[0001] The utility model relates to the technical field of cable trough boxes, in particular to a cable fireproof trough box convenient for maintenance. Background Technique

[0002] A cable fireproof trough box is a facility used to prevent cable lines from catching fire due to external fires or internal failures, and to prevent the spread of fire after the cable catches fire. This kind of trough box is usually made of fire-resistant or flame-retardant materials, such as fiberglass, metal, concrete, etc. Heat-insulating pads or plates are padded inside the trough box, and both ends and interfaces are sealed tightly with fire-resistant materials to form a fire-blocking section. Even if the cables inside the trough box catch fire, it is not easy to be ignited due to the limited air inside the trough box. Its application range is wide, and it is generally used for fire-blocking separation in cable-intensive places such as overhead cables, cable tunnels, cable mezzanines, and cable shafts to achieve the purpose of preventing the spread of cable fires and fire protection (or fire blocking) separation of important cable circuits. In addition, the cable fireproof trough box also has good application value. It can not only be used as a laying channel for cables, making the cable lines uniformly arranged and easy to maintain, but also can be used as a passage for fire-fighting facilities to improve the fire safety of buildings. Therefore, fireproof trough boxes are widely used in the design and decoration of buildings.

[0003] When the existing cable fireproof trough box is in use, it usually adopts the connection method of bolts and nuts to connect the upper box body and the lower box body for use. The tightening degree of the connection between the bolts and nuts depends on the technical level during installation. If they are not correctly aligned or tightened during the installation process, it may lead to loose or damaged connections. When it is necessary to repair the cables, due to the relatively tight fixation of the bolts and nuts, professional tools are needed to disassemble the bolts and nuts, and then the cables in the upper box body or the lower box body can be repaired, thus reducing the maintenance efficiency of the staff. For this reason, we propose a cable fireproof trough box convenient for maintenance. Content of the Utility Model

The experimental methods in the following embodiments are all conventional methods unless otherwise specified. The materials, reagents, etc. used in the following embodiments can all be obtained from commercial channels unless otherwise specified. Embodiment

[0023] Please refer to Figure 1 - Figure 6 , a cable fireproof trough box convenient for maintenance, including an upper box body 1 and a lower box body 2. The upper box body 1 is provided with the lower box body 2. A connecting component 3 is arranged between the upper box body 1 and the lower box body 2. The upper box body 1 is connected to the lower box body 2 through the connecting component 3. A clamping component 4 is arranged inside the lower box body 2, and the clamping component 4 is used to fix the cable.

[0024] By rotating the turning handle 39, the limiting block 38 drives the rotating rod 35 to rotate in the movable bin 33 and the connecting block 34, and the rotating rod 35 drives the torsion spring 36 to be distorted until the rotating rod 35 drives the limiting block 38 to rotate to align with the limiting groove 37. Then, the connecting block 34 is slid out from the rotating rod 35, and the lower box body 2 drives the insertion block 32 to slide out from the insertion slot 31, so as to achieve the purpose of disassembling the lower box body 2, which is convenient for the staff to repair the cables in the lower box body 2 and the upper box body 1. The staff can disassemble the cable fireproof trough box without the aid of tools, and at the same time reduces the disassembly and assembly difficulty of the cable fireproof trough box, further improving the maintenance efficiency of the staff for the cables. Then, by classifying and placing the large and small cables in the first placement groove 45 or the second placement groove 46, the purpose of layered management of the large and small cables is achieved. By loosening the handle 48, the restoring force of the spring 42 is used to push the sliding rod 43 to reset and slide in the sliding cylinder 41, and the two clamping plates 44 are made to fit together, so as to achieve the purpose of clamping and limiting the cable, which is convenient for the staff to maintain and repair it.

[0025] In other embodiments, the connecting component 3 includes two groups of slots 31 opened on the top surface of the lower box body 2. Sliding blocks 32 are slidably arranged in the slots 31. The tops of the sliding blocks 32 are fixedly connected to the lower box body 2. Activity bins 33 are arranged on both side surfaces of the upper box body 1. Connecting blocks 34 are arranged on the outer walls of the lower box body 2 above the activity bins 33. Rotating rods 35 are rotatably arranged in the activity bins 33. Torsion springs 36 are wound around the surfaces of the rotating rods 35. Limit slots 37 are opened on the inner walls of the connecting blocks 34. The rotating rods 35 are slidably connected to the connecting blocks 34. Limit blocks 38 are arranged on the outer walls of the rotating rods 35 at the tops of the connecting blocks 34. The limit blocks 38 and the limit slots 37 are designed in a misaligned manner. Rotating handles 39 are arranged at the tops of the rotating rods 35;

[0026] During use, first, by rotating the rotating handle 39, the rotating handle 39 synchronously drives the limit block 38 to rotate. Then, the limit block 38 drives the rotating rod 35 to rotate in the activity bin 33 and the connecting block 34, and the rotating rod 35 drives the torsion spring 36 to be distorted until the rotating rod 35 drives the limit block 38 to rotate to align with the limit slot 37. Then, the connecting block 34 is slid out from the rotating rod 35, and the lower box body 2 drives the sliding block 32 to slide out from the slot 31, so as to achieve the purpose of disassembling the lower box body 2, facilitating the maintenance of the cables in the lower box body 2 and the upper box body 1 by the staff. When the maintenance is completed, the rotating rod 35 drives the limit block 38 to rotate to align with the limit slot 37. Then, the sliding block 32 is inserted into the slot 31, and the lower box body 2 synchronously drives the limit slot 37 to be sleeved on the limit block 38 until the lower box body 2 fits with the upper box body 1. At this time, the bottom surface of the limit block 38 fits with the top surface of the connecting block 34. Then, the rotating handle 39 is released, and the restoring force of the torsion spring 36 drives the rotating rod 35 to rotate and reset in the activity bin 33, and the rotating rod 35 drives the limit block 38 and the limit slot 37 to be designed in a misaligned manner, thereby achieving the purpose of connecting the upper box body 1 and the lower box body 2.

[0027] It should be noted that the rotating handle 39 is designed in a square shape, and the right-angle parts on the rotating handle 39 are all designed in a rounded shape, which can drive the rotating rod 35 to rotate in the activity bin 33 by rotating the rotating handle 39, preventing the situation that when the staff rotates the rotating rod 35, the hand slips, resulting in the rotating rod 35 returning to its original position under the driving of the restoring force of the torsion spring 36, so that the staff needs to rotate the rotating rod 35 again. The sliding block 32 is designed in a T shape, and the slot 31 is opened as a through hole adapted to the sliding block 32, which can achieve the purpose of positioning the lower box body 2 by inserting the sliding block 32 into the slot 31, aligning the lower box body 2 with the upper box body 1, facilitating the staff to connect the upper box body 1 and the lower box body 2, and further improving the installation efficiency of the upper box body 1 and the lower box body 2.

[0028] In other embodiments, the clamping assembly 4 includes two sets of slides 41 symmetrically arranged on the inner walls of both sides of the upper box body 1 and the lower box body 2, springs 42 are fixedly arranged on the inner walls of the slides 41, the other ends of the springs 42 are fixedly connected to slide bars 43, and the slide bars 43 slide in the slides 41, and the outer end surfaces of the slide bars 43 are provided with clamping plates 44, and the clamping plates 44 are provided with first placement grooves 45 and second placement grooves 46, and connecting plates 47 are arranged between the two sets of slide bars 43, and the surfaces of the slide bars 43 on one side away from the connecting plates 47 are provided with handles 48;

[0029] When in use, first pull the two groups of handles 48 toward the side surface away from the clamping plate 44, so that the handles 48 drive the slide bar 43 to return to its original position and slide in the slide tube 41, and the slide bar 43 synchronously drives the other group of slide bars 43 to slide in the slide tube 41 through the connecting plate 47, and the two groups of slide bars 43 squeeze the two groups of springs 42, then classify the large and small cables, and place the classified cables in the first placement groove 45 and the second placement groove 46 for classified management, and then release the handles 48, use the restoring force of the spring 42 to push the slide bar 43 to return to its original position and slide in the slide tube 41, and make the slide bar 43 drive the clamping plate 44 to fit with the other group of clamping plates 44, so as to achieve the purpose of fixing the cables.

[0030] It is worth noting that the two groups of first placement grooves 45 and the second placement grooves 46 are both provided with cushions on the surface of the side facing away from the upper box body 1, and the cushions are all glued to the inner walls of the first placement groove 45 and the second placement groove 46, which can prevent the cable from making hard contact with the inner walls of the first placement groove 45 or the second placement groove 46 when being clamped by the two groups of clamping plates 44, and causing damage to the cable surface. One end of the spring 42 is welded to the inner wall of the slide cylinder 41, and the other end of the spring 42 is welded to the inner end of the slide rod 43. The slide rod 43 slides linearly in the slide cylinder 41, which can prevent the spring 42 from being displaced in the slide cylinder 41, thereby causing the force output by the spring 42 to the slide rod 43 to be uneven, thereby affecting the sliding stability of the slide rod 43 in the slide cylinder 41.

[0031] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0032] The above has shown and described the basic principles, main features and advantages of the present utility model.
