[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] This utility model provides a technical solution: such as Figures 1 to 4 As shown in this embodiment, a flexible rubber joint for conveying equipment includes a flexible rubber joint body 1 and a connecting flange 2. The flexible rubber joint body 1 is installed in conjunction with the connecting flange 2. The flexible rubber joint body 1 has the same structure as existing flexible rubber joints, consisting of inner and outer rubber layers, a fabric layer, and a steel wire ring. Hard rubber 3 is installed at both apex corners of the flexible rubber joint body 1. The hard rubber 3 is fixedly connected to the apex corners of the flexible rubber joint body 1 by heat fusion technology. The inner ring positions at both ends of the flexible rubber joint body 1 are provided for accommodating the connecting flange. When the flexible rubber joint body 1 is fitted inside the connecting flange 2 using a pry bar, the rigid rubber 3 can support the pry bar's compression, reducing the damage to the existing flexible rubber joint caused by the pry bar's compression and protecting the flexible rubber joint. When the flexible rubber joint body 1 is fitted inside the connecting flange 2, the connecting flange 2 slides into the interior of the mounting groove 4, which can radially position the connecting flange 2 and prevent the connecting flange 2 from sliding outside the flexible rubber joint body 1. This facilitates the subsequent installation between the flexible rubber joint body 1 and the pipeline and improves installation stability.

[0025] like Figures 1 to 4 As shown, the flexible rubber joint body 1 has a chamfer 5 on one side corresponding to the mounting groove 4.

[0026] The chamfer 5 design makes it easy to slide the connecting flange 2 into the mounting groove 4.

The positioning column 7 is integrally formed by pouring the outer rubber in the existing soft rubber joint. The positioning column 7 is slidably inserted into the positioning hole 6.

[0028] The positioning column 7 on the soft rubber joint body 1 corresponds to the positioning hole 6 on the connecting flange 2. The positioning column 7 is inserted into the positioning hole 6 by the elasticity of the positioning column 7. The rotation of the connecting flange 2 can be positioned, and the installation between the soft rubber joint body 1 and the pipeline can be facilitated, and the installation stability is further improved.

[0029] As shown in Figures 1 to 4 , the inner diameter of the mounting groove 4 is slightly larger than the inner diameter of the connecting flange 2.

[0030] When the connecting flange 2 is slid into the inside of the mounting groove 4, the inner wall of the connecting flange 2 can be extruded by the soft rubber joint body 1 at the mounting groove 4, thereby improving the stability of the installation between the soft rubber joint body 1 and the connecting flange 2.

[0031] As shown in Figures 1 to 4 , the two ends of the soft rubber joint body 1 are symmetrically fixedly installed with a sealing gasket 8.

[0032] When the soft rubber joint body 1 with the connecting flange 2 is flange-connected with other pipelines, the sealing property of the connection between the soft rubber joint body 1 and other pipelines can be improved by the sealing gasket 8.

[0033] As shown in Figures 1 to 4 , the inner wall of the soft rubber joint body 1 is integrally provided with rubber hairs 9 in a ring array, equidistantly around the central axis of the soft rubber joint body 1. The rubber hairs 9 are integrally formed by pouring the inner rubber in the existing soft rubber joint.

[0034] The rubber hairs 9 can block the gas or liquid flowing in the soft rubber joint body 1 to a certain extent, reduce the pressure of the gas or liquid flow, reduce the vibration of the pipeline connected with the soft rubber joint body 1, and improve the use effect.

[0035] As shown in Figures 1 to 4 , limit holes 10 are formed in the outer side of the two ends of the soft rubber joint body 1 and the hard rubber 3.

[0036] When the soft rubber joint body 1 provided with the connecting flange 2 is flange-connected with other pipelines, the bolt rod on the connecting flange 2 is passed through the bolt hole on the connecting flange 2, and meanwhile, the bolt rod can be positioned in the limiting hole 10, and a plurality of bolt rods can position the end of the soft rubber joint body 1, so as to improve the end strength of the soft rubber joint body 1.

[0037] The utility model provides a kind of soft rubber joint for conveying equipment, specific working principle as follows:

[0038] When the device is used, the soft rubber joint body 1 is sleeved inside the connecting flange 2 by crowbar, the connecting flange 2 is slid into the inside of the installation slot 4, the position of the connecting flange 2 can be positioned radially, to prevent the connecting flange 2 from sliding outside the soft rubber joint body 1, then rotate the connecting flange 2, the positioning column 7 on the soft rubber joint body 1 is corresponded to the positioning hole 6 on the connecting flange 2, the positioning column 7 is inserted into the inside of the positioning hole 6 by the elasticity of the positioning column 7, the rotation of the connecting flange 2 can be positioned, when the soft rubber joint body 1 provided with the connecting flange 2 is flange-connected with other pipelines, the bolt rod on the connecting flange 2 is passed through the bolt hole on the connecting flange 2, and meanwhile, the bolt rod can be positioned in the limiting hole 10, and a plurality of bolt rods can position the end of the soft rubber joint body 1, so as to improve the end strength of the soft rubber joint body 1, prevent the end of the soft rubber joint body 1 from deforming, when the soft rubber joint body 1 is used to convey gas or liquid, the rubber hair 9 can block the gas or liquid flowing in the inside of the soft rubber joint body 1 to a certain extent, reduce the pressure of gas or liquid flow, reduce the vibration of the pipeline connected with the soft rubber joint body 1, improve the use effect.
