Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of connecting joints, in particular to a self-sealing rubber joint. BACKGROUND

[0002] The existing connection mode of rubber pipes and hard pipes is usually to make the rubber pipe capable of extending outward by heating or pressurizing the inside of the rubber pipe, so that the caliber is enlarged to form an expanded interface, so as to be sleeved outside the hard pipe, and then the rubber pipe and the hard pipe are tightly connected by pipe clamps, iron wires and the like. Such connection mode is efficient, but due to the limited ductility of the rubber pipe, the part of the rubber pipe after extension loses elasticity, which leads to insufficient sealing after disassembly and reconnection of the joint, and the part of the rubber pipe after extension needs to be cut off to make a new expanded interface, which causes waste of the rubber pipe and complicated operation.

[0026] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. Example

[0027] like Figures 1 to 6 As shown, a self-sealing rubber joint comprises a rubber tube 1, the end of the rubber tube 1 is connected to a joint 2, the end of the joint 2 away from the rubber tube 1 is provided with an opening, the opening is rotatably connected to an inner slip ring 3 arranged on the inner side of the joint 2, and a clamping component 4 for closing the opening is provided at the front end of the opening, the clamping component 4 is driven and connected to the inner slip ring 3, the inner slip ring 3 rotates relative to the joint 2 to drive the clamping component 4 to open and thus open the opening, a reset component is provided between the joint 2 and the inner slip ring 3, and a sealing ring 25 is provided on the inner wall of the joint 2. When in use, the inner slip ring 3 is rotatable inside the joint 2, and the clamping component 4 can be driven to open or close by rotating the inner slip ring 3, thereby opening or closing the opening of the joint 2, so that the hard pipe can be inserted into the interface and fixed by the clamping component 4 to form a stable connection, and a sealing ring 25 is provided inside the joint 2. After the hard pipe is inserted into the joint 2, the sealing ring 25 is clamped and fixed between the inner wall of the joint 2 and the outer wall of the hard pipe, thereby sealing the connection end of the joint 2 and the hard pipe.

[0028] Furthermore, a limiting groove 22 is provided on the outer periphery of the joint 2, and the limiting groove 22 passes through the side wall of the joint 2. A first fixing pile 21 is provided at one end of the limiting groove 22, and the first fixing pile 21 is elastically connected to the inner slip ring 3 through a reset assembly.

[0029] Furthermore, the reset assembly includes a second fixed pile 33, which is movably arranged in the limiting groove 22 and one end of the second fixed pile 33 passes through the limiting groove 22 and is connected to the inner slip ring 3, and a reset spring 32 is connected between the first fixed pile 21 and the second fixed pile 33. The second fixed pile 33 is movable in the limiting groove 22, one end of which is connected to the inner slip ring 3, and the other end is connected to the first fixed pile 21 through the reset spring 32. During use, when the inner slip ring 3 rotates, the second fixed pile 33 moves in the limiting groove 22, the first fixed pile 21 is located at one end of the limiting groove 22, and the second fixed pile 33 moves in the limiting groove 22 along the end away from the first fixed pile 21, so that the reset spring 32 is stretched, providing a restoring force for the inner slip ring 3 to be reset, and the inner slip ring 3 rotates to drive the clamping assembly 4 to open, so that the hard pipe can be inserted.

[0030] Further, one end of the adjacent limiting groove 22 on the outer periphery of the connector 2 is also provided with a movable slot 23 penetrating the connector 2, and a handle 34 is slidably connected in the movable slot 23. The other end of the handle 34 is fixedly connected with the inner sliding ring 3. The movable slot 23 limits the sliding range of the handle 34 along the movable slot 23. The other end of the handle 34 is connected with the inner sliding ring 3, which can limit the rotation angle of the inner sliding ring 3, so as to avoid that the inner sliding ring 3 is excessively rotated to cause the return spring 32 to exceed the stretching limit.

[0031] Further, the clamping assembly 4 includes a plurality of clamping blocks 41 arranged in a circumferential array. The clamping block 41 is a triangular structure including two fixed ends. The two fixed ends of the clamping block 41 are respectively fixedly connected with the connector 2 and the inner sliding ring 3. The remaining one free end extends along the radial direction of the connector 2 and is close to the radial center. In use, the fixed end of the clamping block 41 connected with the connector 2 serves as the rotation center, and the fixed end of the clamping block 41 connected with the inner sliding ring 3 serves as the driving end for driving the clamping block 41 to rotate. In normal state, the free end of the clamping block 41 extends along the radial direction of the connector 2 and is close to the radial center. When the inner sliding ring 3 drives the clamping block 41 to rotate, the free end of the clamping block 41 gradually moves away from the center. The plurality of clamping blocks 41 arranged in a circumferential array are synchronously moved under the driving of the inner sliding ring 3, so as to open the opening at the front end of the connector 2, and the rigid pipeline can be inserted into the connector 2. After the rigid pipeline is inserted, the inner sliding ring 3 is reset under the pulling force of the return spring 32, and the inner sliding ring 3 synchronously drives the plurality of clamping blocks 41 to reset, so that the free end of the clamping block 41 abuts against the outer wall of the rigid pipeline. Under the joint action of the plurality of clamping blocks 41, a clamping structure surrounding the outer wall of the rigid pipeline is formed, which can prevent the rigid pipeline from being retracted or loosened after being connected.

[0032] Further, the side wall of the opening end of the connector 2 is provided with a first fixed hole 24, and the one side fixed end of the clamping block 41 is provided with a first pin 42. The first pin 42 passes through the clamping block 41 and is connected with the first fixed hole 24. In use, the first pin 42 is used to fix one fixed end of the clamping block 41, so as to form the origin of rotation of the clamping block 41.

[0033] Further, the side wall of the opening end of the connector 2 is provided with a first fixed hole 24, and the one side fixed end of the clamping block 41 is provided with a first pin 42. The first pin 42 passes through the clamping block 41 and is connected with the first fixed hole 24. In use, the first pin 42 is used to fix one fixed end of the clamping block 41, so as to form the origin of rotation of the clamping block 41.

[0034] Further, the free end of the clamping block 41 is provided with an elastic block 44, which is used to increase the friction between the free end of the clamping block 41 and the outer wall of the rigid pipeline, so as to prevent the rigid pipeline from slipping off after being clamped by the clamping block 41.

[0035] The above specific embodiments are only preferred embodiments of the present application, and based on the technical scheme of the present application and the related inspiration of the above embodiments, those skilled in the art can make various alternative improvements and combinations on the above specific embodiments.
