Description

Faucet mounting structure

Technical Field

The utility model relates to a tap installation technical field, concretely relates to tap mounting structure.

Background

A faucet is a sanitary product widely used in daily life, and is generally fixedly mounted on a table top provided with a through hole, such as a kitchen table top or a bathroom cabinet table top. The traditional mounting structure of the faucet locks by means of a stud and a nut, and then the sealing of the joint of the faucet and the table top is realized by adopting a glass cement filling mode, however, in the daily use process, the faucet is easy to generate thread loosening due to the opening and closing operations of a faucet switch, daily cleaning and other factors, and the glass cement is damaged to cause water leakage, and the cabinet body structure is usually a wooden cabinet body structure arranged below the kitchen table top and the bathroom cabinet table top, so the water leakage easily causes the hidden troubles of mildew, deterioration, even damage and the like of the cabinet body structure, and the service life of the product is influenced.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome the above-mentioned defect or problem that exist among the background art, provide a tap mounting structure, it can prevent reliably that the tap from producing not hard up to guarantee tap and mesa mounting structure's leakproofness.

In order to achieve the purpose, the following technical scheme is adopted:

a faucet mounting structure for securing a faucet to a countertop; the table top is provided with a through hole; the method comprises the following steps: the screw connector extends vertically and is inserted into the through hole, and the outer wall of the screw connector is provided with a first thread and a second thread which are spaced from each other and have the same thread direction; the first thread is used for being in threaded connection with a faucet; the anti-loosening assembly comprises two washers which are sleeved outside the screw connector and are stacked mutually; the surfaces of the two gaskets facing each other are formed with inclined surfaces for matching; the inclined direction of the inclined plane in the inclined plane matching is consistent with the inclined direction of the first thread, and the included angle between the inclined plane and the horizontal plane is larger than the thread lead angle of the first thread; the first sealing gasket is sleeved outside the screw connector, tightly abuts between the top end of the anti-loosening assembly and the lower surface of the table top, and is in sealing fit with the screw connector through elastic deformation; the retaining member, its with second screw thread spiro union and top are tightly supported locking subassembly bottom.

Furthermore, a plurality of inclined planes are arranged on the surfaces, facing each other, of the two gaskets; the inclined planes on each gasket are continuously distributed along the circumferential direction; the inclined planes on the two washers correspond to each other one by one and are matched and attached to each other.

Further, the faces of the two gaskets, which face away from each other, are corrugated faces.

Further, the device also comprises a second sealing gasket; the second sealing gasket is sleeved outside the screw connector and is abutted between the faucet and the upper surface of the table board along the vertical direction, and is in sealing fit with the screw connector through elastic deformation.

Furthermore, the outer wall of the locking piece is provided with anti-skidding protrusions.

Furthermore, the outer wall of the locking piece is provided with a plurality of anti-skid protrusions which are distributed at intervals along the circumferential direction; each of the antiskid projections extends in the vertical direction.

Compared with the prior art, the scheme has the following beneficial effects:

1. among this technical scheme, the vertical extension of spiro union piece and peg graft in the perforating hole, the first screw thread and the leading spiro union of its top outer wall, the second screw thread of its bottom outer wall then supplies the retaining member spiro union, when the retaining member spiro union targets in place, the tap bottom supports with the upper surface of mesa tightly, the retaining member supports through the first sealed lower surface of filling up with locking subassembly and mesa tightly to the realization is fixed in the mesa with the tap. After the faucet is fixed in place, the first sealing gasket is sealed at the periphery of the threaded connecting piece and is in sealing butt joint with the lower surface of the table board, so that water on the table board can be prevented from leaking down, the upper surface of one gasket positioned above the anti-loosening assembly is tightly abutted with the first sealing gasket and forms strong friction with the first sealing gasket, similarly, the lower surface of one gasket positioned below the anti-loosening assembly is tightly abutted with the top end of the locking piece and forms strong friction with the locking piece, namely, the first sealing gasket and the gasket positioned above the anti-loosening assembly are difficult to rotate relative to the table board, the gasket positioned below the anti-loosening assembly is difficult to rotate relative to the locking piece, in the subsequent use process, once the faucet is shaken and leads the threaded connecting piece to have a loosening trend relative to the faucet, the threaded connecting piece can drive the locking piece and the gasket positioned below the anti-loosening assembly to rotate, namely, the inclined plane between the two gaskets can be matched to generate relative rotation, and form lifting tension, and because the inclination angle on inclined plane is greater than the screw thread lead angle of first screw thread in the inclined plane cooperation between two gaskets, therefore, foretell lifting tension can make the screw thread mating reaction between screwed part and the tap produce along the very big pressure of vertical direction, and form huge frictional force, thereby make the screwed part can't take place to become flexible relatively the tap, reach effectual locking effect, and then the gesture of sealed first sealed pad changes, and can seal in screwed part periphery and perforating hole department all the time, ensure that the mesa is water-tight and the cabinet body structure that is located the mesa below does not take place to wet, go mildy and impaired, guarantee the life of product.

2. The two washers are provided with a plurality of inclined planes which are continuously arranged along the circumferential direction, so that when the two washers are dislocated, the axial positions of the two washers are stable, the two washers can respectively form a stable rotation stopping effect with the first sealing gasket and the locking piece, and the reliability of the anti-loosening effect is ensured; in addition, under the condition that two washers are provided with the same inclined plane, the structures of the two washers are consistent, so that only one set of die is needed during molding, and the manufacturing cost is reduced.

3. The one side that two washers deviate from each other all establishes to the corrugated surface, consequently, and under the condition that two washers are supported, its two can form bigger area of contact with first sealed pad and retaining member respectively to form bigger frictional force, in order to promote the effect of splining.

4. The setting of the second sealing gasket is favorable to further promoting the leakproofness that the mesa link up hole department to strengthen the leak protection water effect of mesa, and avoid producing mould because of ponding in the perforating hole.

5. Set up the non-slip raised through the outer wall at the retaining member to guarantee that operating personnel is difficult for skidding when carrying out the selection operation to it, promote the convenience of operation.

6. The more the quantity of anti-skidding arch is, the better the anti-skidding effect of retaining member is, and the feel during operation is also better.
