Description

Locking device for faucet installation

Technical Field

The present invention relates to a faucet assembly assist device, and more particularly, to a locking device for faucet assembly.

Background

The faucet is usually installed on the mesa, and its in the installation, the lower extreme that needs to pass the tap passes the mounting hole on the mesa and makes tap main part joint on the mesa, then makes the tap main part lock fastening on the mesa through nut spiro union at tap lower extreme below the mesa, because the space below the installation mesa is usually very narrow and small, it is very time consuming and laborious for the installer to bore to the installation mesa below and to use the spanner to screw up the nut to lock fixedly to the tap again, and extremely inconvenient.

Disclosure of Invention

In order to overcome the defects in the prior art, the invention provides a locking device for faucet installation.

The technical scheme adopted by the invention is mainly as follows: the utility model provides a locking device for tap installation, includes a cylindric main part, the main part upper end sets up the blank holder of outside extension, and the main part lower extreme is provided with the internal thread that is connected with tap, is provided with elastic expansion portion between main part upper end and the main part lower extreme, thereby expansion portion can be fixed the main part in the mounting hole under axial pressure outside expansion.

As an improvement of the above technical solution, the side wall of the expansion part is provided with a plurality of slits, and the slits extend along the axial direction of the expansion part.

As a further improvement of the above technical solution, the slits are uniformly distributed on the side wall of the expansion portion.

Further, the expansion portion is provided with a reinforcing end near the lower end of the main body, and the reinforcing end expands outwardly.

Further, the reinforcing end is inclined from top to bottom to outside.

Further, the lower end of the main body is inclined from top to bottom outwards.

The beneficial effects of the invention are as follows:

the invention relates to a locking device for faucet installation, which comprises a cylindrical main body, wherein the upper end of the main body is provided with an outwards extending pressing edge, the main body is placed into a mounting hole of a table top during installation, the pressing edge is abutted above the mounting hole, then a faucet with external threads at the lower end is inserted into the main body, the faucet is rotated above the table top, the lower end of the faucet is in threaded connection with the lower end of the main body, the pressing edge of the main body is pressed, the faucet is rotated at the same time, the lower end of the main body is driven to be close to the upper side of the table top, the lower end of the main body close to the upper side of the table top extrudes an expansion part, so that the expansion part is outwards expanded after being stressed and is tightly attached to the inner wall of the mounting hole, the main body can be firmly arranged in the mounting hole, and the faucet is in threaded connection with the main body, so that the locking fixation of the faucet on the table top is realized.

FIG. 2 is a schematic cross-sectional view of FIG. 1;

fig. 3 is a schematic perspective view of the present invention.

Detailed Description

The invention will be described in further detail with reference to the drawings and the detailed description.

Referring to fig. 1 to 3, a locking device for faucet mounting according to the present invention includes a cylindrical main body, an outwardly extending flange 1 is provided at an upper end of the main body, the flange 1 may be provided with a circular or square shape or other shape as required, a lower end 2 of the main body is provided with an internal thread 21 to be connected with a faucet, an elastic expansion part 3 is provided between the upper end of the main body and the lower end 2 of the main body, the expansion part 3 may be made of nylon material or other elastic material, and the expansion part 3 may be outwardly expanded under axial pressure to fix the main body in a mounting hole. When the faucet is installed, the main body is placed into the installation hole of the table top to enable the pressing edge 1 to be abutted above the installation hole, then the faucet with external threads at the lower end is inserted into the main body, the faucet is rotated above the table top to enable the lower end of the faucet to be in threaded connection with the lower end 2 of the main body, the pressing edge 1 of the main body is pressed, the faucet is rotated at the same time to enable the lower end 2 of the main body to be driven to be close to above the table top, the expansion part 3 is extruded towards the lower end 2 of the main body close to the upper side of the table top, the expansion part 3 is expanded outwards after being stressed to be tightly attached to the inner wall of the installation hole, and then the main body can be firmly arranged in the installation hole, and meanwhile the faucet is in threaded connection with the main body, so that the locking fixation of the faucet on the table top is realized.

In the invention, in order to make the lower end 2 of the main body squeeze the expansion part 3 better, the lower end 2 of the main body is preferably inclined from top to bottom and the inner diameter of the internal thread of the lower end 2 of the main body is smaller than the inner diameter of the expansion part 3, so that when the lower end 2 of the main body is pulled upwards by the lower end of the faucet, the lower end 2 of the main body can squeeze the expansion part 3 better to deform the expansion part 3 and expand outwards.

Specifically, the wall thickness of the expansion part 3 is thinner than that of the upper end of the main body and the lower end 2 of the main body, so that the expansion part is easier to deform when being stressed, a plurality of gaps 31 are formed in the side wall of the expansion part 3, the gaps 31 axially extend along the expansion part 3, the extrusion force required by the deformation of the expansion part 3 can be further reduced, the expansion part 3 is divided into a plurality of elastic sheets, the expansion part 3 can be better clung to the inner wall of the mounting hole when being expanded outwards after being deformed, the main body is better fixed in the mounting hole, and preferably, the gaps 31 are uniformly distributed on the side wall of the expansion part 3, so that the expansion part 3 can be more uniformly clung to the inner wall of the mounting hole after being deformed, and the reliability of the main body in the mounting hole is improved.

In the invention, the expansion part 3 is provided with the reinforcing end 32 near the lower end 2 of the main body, the reinforcing end 32 expands outwards, the wall thickness of the reinforcing end 32 is thicker than other areas of the expansion part 3 through the arrangement, so that the reinforcing end 32 near the lower end 2 of the main body can bear larger pressure without damage, and the arrangement of the reinforcing end 32 can enable the extrusion force to be transmitted from the lower end of the expansion part 3 to a position farther than the upper end of the expansion part 3, so that the area of the expansion part 3 expanding outwards is larger. Preferably, the reinforcement end 32 is inclined from top to bottom to outside, so that the reinforcement end 32 is configured to better transmit the pressing force transmitted from the lower end 2 of the main body to the upper end of the expansion part 3.

The foregoing description is only of the preferred embodiments of the invention, and is not intended to limit the invention, so long as the technical solutions for achieving the objects of the invention by substantially the same means fall within the scope of the invention.
