Description

Technical Field

[0001] The utility model relates to the technical field of waterproof rubber sleeves, in particular to a high-temperature waterproof rubber sleeve with excellent weather resistance. Background Art

[0002] Cable is a general term for items such as optical cables and electrical cables. Cables have many uses, primarily controlling installations, connecting devices, and transmitting power. They are common and indispensable in our daily lives. When connecting cables, the insulation layer must be stripped off before the connection is made. Since the stripped cable has no insulation layer after connection, its waterproof and corrosion resistance is poor, so it requires waterproof rubber sleeve protection.

[0003] However, in existing waterproof rubber sleeves, only conventional natural rubber or low-cost synthetic rubber is used. These materials are susceptible to the risk of aging and degradation under the influence of ultraviolet rays, high temperature, low temperature and humidity, and no protective measures are taken on their surface. The impact and stress of the external environment on the material are not taken into consideration, making its structure relatively weak, which in turn accelerates the aging of the waterproof rubber sleeve, resulting in poor weather resistance of the material and causing the waterproof rubber sleeve to break or deform. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a high-temperature waterproof rubber sleeve with excellent weather resistance.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A high-temperature waterproof rubber sleeve with excellent weather resistance includes a rubber sleeve body, a mounting hole passing through the middle of the rubber sleeve body, a threaded mounting groove provided on the inner wall of the mounting hole, and staggered ribs provided on the inner wall of the rubber sleeve body. The staggered ribs are arranged in a grid-like staggered manner on the inner wall of the rubber sleeve body. Annular ribs are fixedly connected to the inner walls of the rubber sleeve body on both sides near the mounting hole, and reinforcing ribs are provided in the inner wall of the rubber sleeve body on one side near the staggered ribs.

[0007] Preferably, an annular boss is provided on the top of the rubber sleeve body, a plurality of clamping grooves are provided on the bottom of the annular boss, and a fixing block matched with the clamping grooves is fixedly connected to the outer wall of the rubber sleeve body.

[0008] Preferably, the outer wall of the rubber sleeve body is provided with a plurality of guide ribs and protruding particles, and ventilation and heat dissipation grooves are provided on the upper and lower sides of the rubber sleeve body.

[0009] Preferably, the rubber sleeve body is made of high-performance elastomer material.

[0010] The beneficial effects of the utility model are:

[0011] When the waterproof rubber sleeve is subjected to internal and external pressure, the staggered ribs and annular ribs arranged inside the waterproof rubber sleeve can provide strong internal support for the waterproof rubber sleeve, effectively disperse the force, avoid local stress concentration, and increase the overall rigidity of the structure. Reinforcement ribs are used to support the joints of the waterproof rubber sleeve and withstand high stress areas, reducing the risk of rupture of the waterproof rubber sleeve, improving the weather resistance of the waterproof rubber sleeve, enhancing the rigidity, and reducing material deformation.

[0012] The guide ribs opened on the outside of the waterproof rubber sleeve can effectively guide the water flow to the outside, help reduce the retention of water on the surface of the waterproof rubber sleeve, and reduce the risk of moisture penetration. The ventilation and heat dissipation grooves increase the contact area between the waterproof rubber sleeve and the outside, which can promote air flow on the surface of the waterproof rubber sleeve, effectively reduce the direct exposure time of ultraviolet rays to the surface of the waterproof rubber sleeve, reduce the internal temperature, help heat diffusion, and improve the high temperature resistance of the waterproof rubber sleeve.

[0022] Example:

[0023] Reference Figure 1-4 A high-temperature waterproof rubber sleeve with excellent weather resistance includes a rubber sleeve body 1, a mounting hole 2 is passed through the middle of the rubber sleeve body 1, a threaded mounting groove 3 is provided on the inner wall of the mounting hole 2, and staggered ribs 4 are provided on the inner wall of the rubber sleeve body 1. The staggered ribs 4 are arranged in a grid-like staggered manner on the inner wall of the rubber sleeve body 1. Annular ribs 5 are fixedly connected to the inner walls of both sides of the rubber sleeve body 1 near the mounting hole 2, and reinforcing ribs 6 are provided in the inner wall of the rubber sleeve body 1 on one side near the staggered ribs 4.

[0024] An annular boss 7 is provided on the top of the rubber sleeve body 1 , and a plurality of clamping grooves 8 are provided on the bottom of the annular boss 7 . A fixing block 9 that matches the clamping grooves 8 is fixedly connected to the outer wall of the rubber sleeve body 1 .

[0025] The outer wall of the rubber sleeve body 1 is provided with a plurality of guide ribs 10 and protruding particles 11 , and ventilation and heat dissipation slots 12 are opened on the upper and lower sides of the rubber sleeve body 1 .

[0026] The rubber sleeve body 1 is made of high-performance elastomer material.

[0027] In this embodiment, the cable is passed through the mounting hole 2 of the rubber sleeve body 1, and the threaded mounting groove 3 is used to complete the connection between the cable and the rubber sleeve body 1. The staggered ribs 4 are arranged vertically and horizontally inside the rubber sleeve body 1. The staggered ribs 4 can provide enhanced support for the inner wall of the rubber sleeve body 1 by staggering the staggered ribs 4, which can disperse the internal pressure and stress, making the internal structure of the rubber sleeve body 1 more solid, reducing the possibility of deformation or rupture caused by environmental factors, and at the same time, the staggered ribs 4 can help the interior of the rubber sleeve body 1 to better disperse the temperature gradient, reduce the thermal stress caused by local high temperature, thereby reducing the risk of material deformation and enhancing high temperature resistance.

[0028] Specifically, by providing annular ribs 5 along the circumferential direction of the rubber sleeve body 1, when the rubber sleeve body 1 is subjected to internal and external pressure, the force can be effectively dispersed, local stress concentration is avoided, and the overall rigidity of the structure is increased. By providing reinforcing ribs 6 in the inner wall of the rubber sleeve body 1 to support the connection of the rubber sleeve body 1 and withstand high stress areas, the risk of rupture of the rubber sleeve body 1 is reduced, and the weather resistance of the rubber sleeve body 1 is improved. The annular boss 7 is provided on the top of the rubber sleeve body 1, which serves as a fixed point to enhance the connection with other components, while increasing the volume of the inner cavity, improving the rigidity, and reducing the deformation of the material.

[0029] By using the guide ribs 10 opened on the outside of the rubber sleeve body 1, when water flows onto the rubber sleeve body 1, the guide ribs 10 can be used to guide the water to flow to the outside, which helps to reduce the retention of water on the surface of the rubber sleeve body 1 and reduce the risk of moisture penetration. The several ventilation and heat dissipation grooves 12 opened on the surface increase the contact area between the rubber sleeve body 1 and the outside, which can promote air flow on the surface of the rubber sleeve body 1 and effectively reduce the direct exposure time of ultraviolet rays to the surface of the rubber sleeve body 1, thereby reducing the aging rate of the material, improving the toughness of the rubber sleeve body 1, and further improving the weather resistance and high temperature resistance of the rubber sleeve body 1.
