Description

Faucet fixing device

This creation relates to a fixture, especially a fixture for a faucet.

Generally, when the faucet (or faucet) is mounted on the table body, for example, the faucet is installed on the table of the flow table or the table of the wash table, as shown in the fifth figure, when installing a faucet (5), Overall, the pipe (9) connected to the faucet (5) is usually located under a body (8) without being exposed on the table (8), and only the faucet (5) is exposed on the table. The body (8), so the table body (8) usually has a hole (81) extending through the table body (8) for the faucet (5) to be worn, and generally the faucet (5) is fixed to the table The body (8) is connected by a screw (6) to the lower portion of the faucet (5), the screw (6) is disposed behind the hole (81), and since the outer diameter of the faucet (5) is larger than the hole (81) the inner diameter, so the faucet (5) is still placed on the table body (8); and then screwed up with the screw (6) under the table body (8) by a nut (7), The outer diameter of the nut (7) is larger than the inner diameter of the hole (81) to fix the faucet (5); however, since the lower portion of the general table (8) is provided for the pipe (9) In addition, the lower part is usually a storage space, and the storage space has a certain Degree, and the faucet (5) is usually installed near the wall, that is, at a deeper position, and the faucet (5) is fixed by means of the nut (7) under the table (8). The screwing is therefore inconvenient for the construction workers; therefore, the creator believes that there is a need for improvement.

In order to solve the deficiencies of the prior art, the creator proposes a fixing device for a faucet, comprising a faucet and a hollow tube section at the root thereof, and a fixing device, the fixing device comprising an expansion nut, and the expansion screw The cap comprises a first tube body with a hollow end at both ends, and an outer step edge extending radially along the outer peripheral wall of the upper portion of the first tube body, the outer step edge being adapted to abut the hole edge of the hole of the body; a first thread segment and an inner step are continuously disposed on an inner upper portion of the pipe body, and the first pipe body is provided with a plurality of axial slits under the outer edge to form a plurality of petals; the inner edge is available a thickness range of the body; and an expansion screw, the expansion screw includes a second tube body having a space at both ends, and an outer wall having a second thread portion corresponding to one of the first thread segments, the second thread The lower portion of the segment is defined as a lower portion, the outer diameter of the second thread segment is larger than the outer diameter of the lower portion, and the outer diameter of the lower portion is larger than the inner diameter of the inner edge without the width, the expansion screw is screwed into the first tube In order to cause radial movement of each of the petals, the lower portion of the expansion nut is gradually widened. Two thread segments abuts to the bottom edge of the stage is fixed; the second thread segments in the above section defined as an upper portion, and the upper portion of the expansion nut exposed, the tap of the pipe section connected to the upper portion.
The outer diameter of the second thread portion of the expansion screw is larger than the outer diameter of the lower portion, and the outer diameter of the lower portion is larger than the inner portion of the lower portion. The inner diameter of the edge is such that when the expansion screw is screwed into the first tube body, the lower portion causes the respective petals to move radially, and the outer diameter of the lower portion of the expansion nut is larger than the inner diameter of the hole to allow the expansion The nut can be fixed to the table body; since the inner edge can be located in the thickness range of the table body, the inner diameter of the inner step edge is made wider than the diameter of the second thread segment, Adhering the bottom end of the second thread segment to the inner edge to fix the expansion screw to the expansion nut; and the upper portion is exposed to the expansion nut, so that the pipe section of the faucet is connected to the upper section of the expansion screw By this creation, the faucet can be operated on the table body during the installation and fixing process without the need for the operation of the table body, which makes the user more convenient in operation or construction.
