Detailed Description
The following detailed description of the present invention is made with reference to the accompanying drawings. As shown in fig. 1-5.
Example 1: a hardware fitting for pipe connections, comprising: the main connecting pipe is provided with at least two connectors, each connector is provided with n concave annular grooves which are respectively a 1 st concave annular groove, a 2 nd concave annular groove, a … … th concave annular groove … … and an nth concave annular groove from outside to inside, and the depth of the concave rings is gradually increased from outside to inside; further comprising: the 1 st waterproof ring, the … … th waterproof ring … … and the (n-1) th waterproof ring are respectively matched with the 1 st concave annular groove, the … … th concave annular groove … … and the (n-1) th concave annular groove; when the jth concave annular groove is sleeved with a pipe, the 1 st concave annular groove and the … … th (j-1) th concave annular groove are respectively sleeved with a 1 st waterproof ring and a … … th (j-1) th waterproof ring; wherein: n, i and j are natural numbers, and n is greater than 2; n is greater than i, and n is greater than or equal to j and greater than 1.
In order to be conveniently connected with pipes with different pipe diameters, the interfaces of the main connecting pipe are provided with concave annular grooves with different sizes, and the inner diameter of each concave annular groove is matched with the outer diameter of the pipe, so that the interfaces of the main connecting pipe can be connected with the pipes with different pipe diameters through the different concave annular grooves; when the pipe is connected with the interface, the pipe is of a sleeve structure, and a waterproof ring is arranged in the technical scheme for achieving the waterproof and anti-leakage effects; the 1 st concave annular groove is only used for installing the 1 st waterproof ring and is not connected with the pipe; for example: 1. when the 2 nd concave annular groove is sleeved with the pipe, the 1 st concave annular groove is provided with a 1 st waterproof ring, and the 1 st waterproof ring is sleeved outside the pipe; 2. cup joint with tubular product when 3 rd indent ring channel, 1 st indent ring channel is equipped with the waterproof circle of 1 st, and 2 nd indent ring channel is equipped with the waterproof circle of 2 nd, and the waterproof circle of 2 nd overlaps outside tubular product, and the waterproof circle of 1 st overlaps outside the waterproof circle of 2 nd, mainly carries out waterproofly through the waterproof circle of 2 nd. 3. When the t-th concave annular groove is sleeved with the pipe, the 1 st, the 2 nd and the … … th (t-1) th waterproof rings are sequentially sleeved, the (t-1) th waterproof ring is sleeved outside the pipe, 2< t < n +1, and t is a natural number. Because two interfaces can all install the tubular product of multiple model, consequently when connecting, can carry out the tubular product of two not unidimensional and connect.
Further, the depth difference of any two adjacent concave annular grooves is equal.
In order to facilitate processing and installation, the depth value of the concave annular groove is set to be an arithmetic progression.
Furthermore, a compression ring is sleeved outside the interface, the outer side surface of the interface is obliquely arranged, and the outer diameter of the interface is gradually increased from outside to inside; the inner side surface of the compression ring is also obliquely arranged, and the inner cavity space of the compression ring is arranged in a circular truncated cone shape; the clamp ring is sleeved with the interface, and the inner side surface of the clamp ring is abutted to the outer side surface of the interface.
The pressing ring is sleeved with the interface, and the position of the pressing ring is adjusted to form different resisting forces on the interface; and pressing the interface inwards to assist in compressing the waterproof ring and the pipe.
Further, the clamp ring is provided with an internal thread, the interface is provided with an external thread, and the clamp ring is in threaded connection with the interface.
Through the mode of threaded connection for the position at the interface can be adjusted through rotatory mode to the clamp ring, adjusts the shrink power of interface. Preferably, the side face of the interface is provided with a plurality of slits in an axial array. After the gap is arranged, the connector is convenient to bend inwards.
Furthermore, a fastening threaded hole is formed in the side face of the compression ring, and a fastening bolt is connected to the side face of the compression ring.
