Description

Water pipe capable of being quickly connected and assembled

Technical Field

The invention relates to the field of water pipe assembly, in particular to a water pipe capable of being quickly connected and assembled.

Background

Water pipes are indispensable appliances for supplying water. For ease of manufacture and transportation, the water pipes are typically made in shorter sizes and then transported to a destination for use in assembling and connecting the water pipes. At present, two adjacent water pipes need special joints, on one hand, the connection and assembly time of the water pipes is prolonged, on the other hand, corresponding joints need to be produced, and the manufacturing cost is improved.

Disclosure of Invention

In summary, in order to overcome the defects of the prior art, the technical problem to be solved by the invention is to provide a water pipe capable of being quickly connected and assembled.

The technical scheme for solving the technical problems is as follows: a water pipe capable of being quickly connected and assembled comprises a plurality of first pipe bodies and a plurality of second pipe bodies; the two ends of the first pipe body are spherical joints, and the outer diameter of each joint is matched with the inner diameter of the second pipe body; the joint is used for being inserted into the end part of the second pipe body so as to connect the two second pipe bodies through the first pipe body; rubber sheets are fixed on the inner walls of the two ends of the second pipe body, and round holes for the joints to penetrate through are formed in the rubber sheets after the joints are inserted into the end parts of the second pipe body; the inner wall of the second pipe body is provided with a circle of first grooves corresponding to one side, close to the middle part of the second pipe body, of the rubber sheet, the joint penetrates through the round hole, the rubber sheet is pushed into the first grooves to be smoothly inserted into the second pipe body in a forward movement mode, and the joint penetrates through the round hole and cannot be withdrawn backwards under the action of the rubber sheet.

The invention has the beneficial effects that: this water pipe is when connecting the assembly, with the both ends of first body insert respectively adjacent two second bodys can, shortened the assemble duration and need not special joint.

On the basis of the technical scheme, the invention can be further improved as follows:

further, the sum of the thickness of the rubber sheet and the outer diameter of the joint is larger than the inner diameter of the second pipe body, so that the joint cannot retreat backwards from the second pipe body under the action of the rubber sheet.

The beneficial effect of adopting the further scheme is that: guarantee that first body can not reverse the back and withdraw from after inserting the second body, prevent that first body and second body from breaking away from.

Furthermore, a circle of second grooves for preventing the rubber sheet from being extruded are formed in the end part of the first pipe body.

The beneficial effect of adopting the further scheme is that: first body with the second body is connected the assembly back rubber piece and is in the second recess, prevents that the rubber piece from because the extrusion of receiving first body tip always damages.

Further, the first groove is of a conical structure, the end portion, close to the second pipe body, of the first groove is small, and the middle portion, close to the second pipe body, of the first groove is large.

The beneficial effect of adopting the further scheme is that: the rubber sheet can be smoothly pushed into the first groove when the joint penetrates through the round hole.

Furthermore, a sealing ring for sealing the second pipe body and the first pipe body is arranged in the end part of the second pipe body.

The beneficial effect of adopting the further scheme is that: prevent dew between first body and the second body.

Detailed Description

The principles and features of this invention are described below in conjunction with the following drawings, which are set forth by way of illustration only and are not intended to limit the scope of the invention.

As shown in fig. 1 and 2, a quick-connect assembled water pipe includes a plurality of first pipe bodies 1 and second pipe bodies 2. The both ends of first body 1 are globular and the external diameter with second body 2 internal diameter assorted connects 3. The joint 3 is adapted to be inserted into an end of the second pipe body 2 to connect the two second pipe bodies 2 with each other through the first pipe body 1. And a sealing ring 8 for sealing between the second pipe body 2 and the first pipe body 1 is arranged in the end part of the second pipe body 2. And rubber sheets 4 are fixed on the inner walls of the two ends of the second pipe body 2, and round holes 5 for the joints 3 to pass through are arranged on the rubber sheets 4 after the joints 3 are inserted into the end parts of the second pipe body 2. The inner wall of the second pipe body 2 is provided with a circle of first grooves 6 corresponding to one side, close to the inside of the second pipe body 2, of the rubber sheet 4, the joint 3 penetrates through the round hole 5 and pushes the rubber sheet 4 into the first grooves 6 to smoothly move forwards and insert into the second pipe body 2, and the joint 3 penetrates through the round hole 5 and then cannot retreat backwards under the action of the rubber sheet 4 from the second pipe body 2. Preferably: the first groove 6 is of a conical structure, and is small at the end part close to the second pipe body 2 and large at the middle part close to the second pipe body 2. And a circle of second grooves 7 for preventing the rubber sheet 4 from being extruded are arranged at the end part of the first pipe body 1.

When the first pipe body 1 and the second pipe body 2 are connected and assembled, the joint 3 of the first pipe body 1 is inserted into the end part of one second pipe body 2, and the rubber sheet 4 penetrates through the round hole 5 in the process of inserting the joint 3. In the process of passing through the round hole 5, the joint 3 pushes the rubber sheet 4 into the first groove 6 corresponding to the side wall of the periphery of the round hole 5, so that the rubber sheet 4 can be smoothly passed through the round hole 5. When the joint 3 penetrates through the rubber sheet 4 and receives external force to withdraw from the second pipe body 2, the joint still can penetrate through the rubber sheet 4 from the round hole 5 to move outwards towards the end part of the second pipe body 2, and the side wall of the rubber sheet 4 can be positioned between the joint 3 and the inner wall of the second pipe body 2 because the first groove 6 is not arranged in the direction. Because the sum of the thickness of the rubber sheet 4 and the outer diameter of the joint 3 is larger than the inner diameter of the second pipe body 2, the joint 3 cannot retreat backwards from the second pipe body 2 under the action of the rubber sheet 4, and the connection of one end of the first pipe body 1 and one end of the second pipe body 2 is completed. And finally, connecting the first pipe body 1 to one end of another second pipe body 2, and so on until all the first pipe bodies 1 and the second pipe bodies 2 are connected and assembled.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
