Description

Technical Field

[0001] The utility model relates to the technical field of building engineering waterproofing, in particular to a rubber waterproof plugging joint for a cable casing on an outer wall of a basement. Background Art

[0002] Normally, after the cable sheathing is pre-buried in groups on the outdoor wall of the basement, the cable sheathing will be sealed later to prevent water from outdoors from flowing into the basement through the cable sheathing.

[0003] After searching, a Chinese patent with publication number CN211779431U discloses a waterproof sealing structure for a basement cable casing, including a cable body, which is placed inside a pipe, and a cover shell is inserted at the left and right ends of the pipe, a slider is fixedly connected to the right side of the bottom end of the cover shell, and the slider is inserted on the surface of the pipe, blocks are fixedly connected to the upper and lower ends of the right side of the cover shell, a rotating rod is laterally inserted inside the cover shell, and the right side of the rotating rod is inserted inside a second slot, the second slot is fixed on the surface of the pipe, a knob is fixedly connected to the left side of the rotating rod, and the inner wall of the pipe is in contact with the surface of the sealing ring.

[0004] Based on the above search combined with the existing technology, we found that;

[0005] The existing plugging method generally uses cement mortar for plugging, which is to mix fine stone concrete with expansion agent evenly. This method is relatively complicated to construct and may easily lead to inadequate fixing of the cable and insufficient plugging, which may easily cause water leakage in the later stage, so it has certain limitations. Utility Model Content

[0006] In order to solve the above technical problems, the utility model proposes a rubber waterproof sealing joint for the basement outer wall cable casing. The rubber waterproof joint can effectively seal and waterproof the basement outer wall cable casing, and the operation and installation are convenient and practical.

[0007] The technical solution for achieving the purpose of the utility model is: a rubber waterproof sealing joint for the cable sleeve on the outer wall of the basement, including a wall sleeve, a rubber waterproof joint is fixedly installed on the end of the wall sleeve, one end of the rubber waterproof joint is sleeved with a polyester cord cloth, and a stainless steel clamp 1 and a stainless steel clamp 2 are respectively sleeved on one end of the rubber waterproof joint close to the wall sleeve and the polyester cord cloth.

[0008] In some embodiments, a rubber ring is fixedly installed inside one end of the rubber waterproof joint close to the polyester cord fabric.

[0009] In some embodiments, a pair of fastening blocks are slidably installed at the end of the rubber waterproof joint close to the wall sleeve, a pair of springs are fixedly connected between the pair of fastening blocks, and each of the springs is provided with a spring protection cover.

[0010] In some embodiments, a rubber sealing block is fixedly installed inside the rubber waterproof joint, and a reserved hole is opened on the rubber sealing block.

[0011] Compared with the prior art, the present invention has the following significant advantages:

[0012] First: the utility model utilizes a rubber waterproof joint to pre-buried the wall sleeve, and then uses two stainless steel clamps to ensure that the joint can be firmly fixed on the wall sleeve. The rubber ring arranged at the end can prevent outdoor water from entering the basement through the sleeve in the early stage, and can facilitate the cable to pass through the sleeve in the later stage. In addition, the cooperation of the fastening block and the spring at the end can further improve the fixing strength of the rubber waterproof joint and the wall sleeve to prevent loosening. A rubber sealing block and a reserved hole are arranged inside, and the cable passes through the reserved hole to further improve the sealing and waterproof performance of the device.

[0013] Secondly, the utility model can pass cables of different specifications. It only needs to use a utility knife to make a circular cut of corresponding size at the end of the rubber cable connector according to the specifications of the cable. In addition, no other sealing mortar or other materials are required. It only needs to tighten the stainless steel clamp, which saves materials, reduces labor costs, and is highly practical.

[0014] It solves the problem that the existing sealing method generally uses cement mortar for sealing. The fine stone concrete with added expansion agent is evenly mixed. This method is more complicated to construct and may easily lead to the cable not being fixed in place and insufficient sealing, which may easily cause water leakage in the later stage.

[0022] The utility model is described in detail below, and the technical solutions in the embodiments of the utility model are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The utility model provides a rubber waterproof plugging joint for the cable casing of the basement outer wall through improvement. The technical solution of the utility model is:

[0024] Embodiment 1

[0025] like Figure 1-2 As shown, the rubber waterproof sealing joint of the cable sleeve on the outer wall of the basement includes a wall sleeve 1, a rubber waterproof joint 2 is fixedly installed at the end of the wall sleeve 1, one end of the rubber waterproof joint 2 is sleeved with a polyester cord cloth 5, and a stainless steel clamp 1 3 and a stainless steel clamp 2 4 are respectively sleeved on the end of the rubber waterproof joint 2 close to the wall sleeve 1 and the polyester cord cloth 5. The set rubber waterproof joint 2 can effectively seal and waterproof the end of the wall sleeve 1, and the rubber waterproof joint 2 is fixed by the stainless steel clamp 1 3 and the stainless steel clamp 2 4 to ensure that the connection will not be loose, thereby improving the sealing performance of the device.

[0026] like Figure 1-2 As shown, in one embodiment, a rubber ring 6 is fixedly installed inside one end of the rubber waterproof joint 2 close to the polyester cord fabric 5. The rubber ring 6 arranged at the end has a good sealing effect. At the same time, different holes can be opened according to the diameter of the cable to facilitate the cable to pass through, thereby improving the practicality of the device.

[0027] Embodiment 2:

[0028] Based on the rubber waterproof plugging joint for basement outer wall cable casing provided by the first embodiment of the present application, the second embodiment of the present application proposes another rubber waterproof plugging joint for basement outer wall cable casing. The second embodiment is only a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0029] The second embodiment of the utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0030] like Figure 3-4 As shown, in the second embodiment, a pair of fastening blocks 7 are slidably installed at the end of the rubber waterproof joint 2 near the wall sleeve 1, and a pair of springs 9 are fixedly connected between the pair of fastening blocks 7. A spring protection cover 8 is sleeved on each spring 9. By utilizing the cooperation between the fastening block 7 and the spring 9, when in use, the fastening block 7 is opened. After installation, the fastening block 7 will be driven to move inward under the action of the spring 9, so that the rubber waterproof joint 2 and the wall sleeve 1 can be fixed more firmly. In addition, the spring protection cover 8 is made of rubber material, which can move with the fastening block 7 while protecting the spring 9.

[0031] like Figure 3-4 As shown, in the second embodiment, a rubber sealing block 10 is fixedly installed inside the rubber waterproof joint 2, and a reserved hole 11 is opened on the rubber sealing block 10. The sealing performance of the device can be further improved by the rubber sealing block 10 arranged inside. At the same time, the diameter of the reserved hole 11 is smaller than that of the cable. According to the characteristics of the rubber material, when the cable passes through the reserved hole 11, the reserved hole 11 will fit tightly to the surface of the cable, thereby playing a role of sealing and waterproofing.
