Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.
An embodiment of the present invention provides a cable flame retardant structure, which can be seen in fig. 1, and includes: base 1, fire-retardant piece 2, sealing member 3.
The middle part of base 1 is seted up and is supplied the cable mouth 11 that the cable passed, and sets up the accepting groove 12 that encircles cable mouth 11 on the base 1, and accepting groove 12 is used for filling fire-retardant piece 2. Since the housing groove 12 has a ring shape, the flame retardant member 2 filled in the housing groove 12 surrounds the cable in the cable port 11. Wherein fire-retardant 2 has fire-retardant thermal-insulated function, when the condition of a fire appears, can effectively avoid spreading of the condition of a fire under the thermal-insulated fire-retardant effect of fire-retardant 2. The sealing member 3 is mounted to the base 1 to close the receiving groove 12, thereby protecting the flame retardant member 2 in the receiving groove 12. The sealing member 3 is composed of a plurality of splicing parts 31, and the splicing parts 31 are detachably connected with each other. When maintaining and overhauing fire-retardant member 2, can dismantle each concatenation 31 one by one, the cable of wearing to establish from cable mouth 11 can not hinder the dismantlement of sealing member 3.
It can be understood that the receiving groove 12 is an annular structure surrounding the cable port 11, and the corresponding sealing member 3 is also an annular structure surrounding the cable port 11, so that the cable penetrating through the cable port 11 also penetrates through the sealing member 3, and if the sealing member 3 is an integral body which cannot be disassembled, the sealing member 3 is difficult to separate from the cable, and the maintenance of the flame-retardant member 2 is disturbed. In order to enable the seal 3 to disengage from the cable, the number of splices 31 needs to be at least two, so that the two splices 31 disengage from the cable in a direction away from each other. The number of splices 31 can also be planned reasonably by the designer according to the actual construction conditions.
In a preferred embodiment, the base 1 further includes a plurality of ribs 13, the plurality of ribs 13 are arranged along the extending direction of the receiving slot 12, and two ends of each rib 13 are respectively fixed on two opposite inner walls of the receiving slot 12 to support the receiving slot 12, so as to enhance the deformation resistance of the base 1. Meanwhile, the reinforcing ribs 13 can also play a role in fixing the flame-retardant part 2, and the flame-retardant part 2 can be firmly involved in the accommodating groove 12 only by adopting a proper fixing means to connect the flame-retardant part 2 and the reinforcing ribs 13.
Any detachable connection mode, such as bolt connection, snap connection, etc., can be adopted between the splicing parts 31, as long as the splicing parts 31 are relatively fixed. In a preferred embodiment, the base 1 is provided with a plurality of insertion slots 14 corresponding to the splicing portions 31 one by one, the splicing portions 31 are provided with insertion keys 311, and the insertion keys 311 are embedded in the insertion slots 14. By means of the key slot matching between the splicing key 311 and the splicing groove 14, the relative position between the splicing parts 31 and the base 1 can be fixed, and further the relative position between each splicing part 31 can be fixed, and the requirements can be met only by ensuring that the edges of the adjacent splicing parts 31 can be smoothly butted.
In a preferred embodiment, one end of the base 1 extends out of the connecting plate 15 along the radial direction, the connecting plate 15 is provided with a connecting hole 151, the main body of the base 1 is embedded into a mounting hole which is arranged in the wall in advance, the connecting plate 15 is pressed against the wall surface, and the wall body is driven into the connecting hole 151 by using an expansion bolt, so that the connecting plate 15 and the wall body are fixed. The base 1 can be stably fixed on a wall body, and the base 1 is prevented from being loosened due to axial displacement of the base 1 along the mounting opening.
Since there is a certain gap between the cable port 11 and the cable, if the gap is too large, a fire may spread through the gap between the cable port 11 and the cable. In a preferred embodiment, as can be seen in fig. 2, the cable flame-retardant structure further comprises a filling assembly 4, the filling assembly 4 comprises an elastic member 41 and two oppositely arranged clips 42, the clips 42 are capable of moving along the radial direction of the cable port 11, the elastic member 41 connects the two clips 42, and the two clips 42 have elastic force for enabling the two clips 42 to approach each other. The two clips 42 will clamp the cable in the cable port 11, so that the cable is gathered in the gap between the two clips 42, and at the same time, the clips 42 will partially shield the cable port 11, avoiding the problem of too large gap between the cable port 11 and the cable.
In order to further reduce the gap between the cable port 11 and the cable, in a preferred embodiment, the flexible flame-retardant pad 421 is installed at the contact end of the clip 42 and the cable, and the flexible flame-retardant pad 421 has a certain deformation capability and can be attached to the outer contour of the cable to fill the gap between the two clips 42, thereby improving the isolation effect of the flame-retardant structure.
The clip 42 needs to move relative to the base 1, as long as the structure satisfying the function is feasible, in a preferred embodiment, two opposite guide grooves 16 are formed on the base 1, a sliding key 422 extends from each clip 42, and the two sliding keys 422 are respectively slidably embedded in the two guide grooves 16, so that the clip 42 can slide along the guide grooves 16.
On the basis of the above scheme, the elastic member 41 includes two springs 411, the two springs 411 respectively correspond to the two clips 42, one end of the spring 411 abuts against the clip 42, and the other end abuts against the base 1.
In a preferred embodiment, the base 1 is a corrosion resistant stainless steel base, although other non-combustible materials may be used.
In addition, a partition wall loaded with the cable flame-retardant structure is also provided.
Firstly, the main body of the base 1 is embedded in the mounting opening of the wall body, and the base 1 and the wall body are connected through expansion bolts, so that the stability of the base 1 is ensured. The flame-retardant piece 2 is embedded into the accommodating groove 12, so that the whole flame-retardant structure has the flame-retardant and heat-insulating effects, the accommodating groove 12 is sealed by the sealing piece 3 to protect the flame-retardant piece 2, and finally, the cable penetrates through the cable opening 11. When the fire-retardant piece 2 needs to be overhauled and maintained, the splicing parts 31 surrounding the cables can be detached one by one, so that the sealing element 3 is completely detached. The problem that the sealing element 3 is difficult to separate from the cable due to the fact that the sealing element 3 is sleeved on the cable is avoided, and the difficulty in overhauling and maintaining the flame-retardant element 2 is reduced.
The above-described embodiments of the present invention should not be construed as limiting the scope of the present invention. Any other corresponding changes and modifications made according to the technical idea of the present invention should be included in the protection scope of the claims of the present invention.
