Description

Technical Field

[0001] The utility model belongs to the technical field of faucet accessories and relates to a faucet quick installation component. Background Art

[0002] At present, the installation method of the faucet on the basin is mainly to lock it with a nut. The bottom of the faucet is connected to a connecting tube, which is inserted into the installation hole of the countertop, and then the nut is put on the connecting tube under the countertop and tightened. Due to the small space under the countertop and poor light, the installation operation is inconvenient.

[0003] In order to improve the convenience of faucet installation, the installation structure of the faucet is modified. For example, a quick-installation structure on a faucet table is publicly proposed in Chinese patent literature [application number: CN 201820485549.8; announcement number: CN208152161 U], which includes a fixing seat with a diameter larger than the table mounting hole and a bracket that can pass through the table mounting hole. The outer periphery of the fixing seat cooperates with the faucet valve body, and bolts and limit rods are connected between the fixing seat and the bracket. Clamps are hinged on both sides of the bracket, and the clamps expand outward relative to the bracket under the action of a torsion spring.

[0004] When installing the faucet on the sink countertop, you first need to overcome the elastic force of the torsion spring and press the two clamps inward so that the two clamps are relatively close to each other; then control the clamps and the bracket to pass through the mounting hole of the countertop; when the clamps and the bracket are completely through the mounting hole, the two clamps are unfolded under the action of the torsion spring; then use a screwdriver or wrench or other tools to tighten the bolts, and fix the fixing base on the sink countertop through the bracket and the clamp; finally, connect the faucet to the fixing base.

[0005] Although the above-mentioned quick-install structure on the faucet table can be used to perform installation operations without going under the table, it is necessary to press the clamping plate inward with fingers during installation, which can easily cause pain to the fingers and the operation is not comfortable enough. Utility Model Content

[0006] The purpose of the utility model is to solve the above problems existing in the prior art and to propose a faucet quick installation component, thereby solving the technical problem that the existing installation components are not comfortable enough to operate.

[0007] The purpose of the utility model can be achieved through the following technical solutions:

[0008] A faucet quick installation assembly comprises a base for connecting to the faucet and a fixing plate located below the base, the base is provided with a bolt threadedly connected to the fixing plate, and the base is also fixed with a positioning rod that passes through the fixing plate and is parallel to the bolt. The invention is characterized in that a positioning member is provided between the base and the fixing plate, the rod portion of the bolt and the positioning rod are also passed through the positioning member, and the positioning member comprises two mutually hinged positioning seats, the two positioning seats are in an unfolded state under the action of gravity and rest against the fixing plate, and the ends of the two positioning seats that are away from each other in the unfolded state both protrude from the outer side surface of the fixing plate, and the two positioning seats can be rotated upward and relatively close to each other.

[0009] The installation holes on the countertop are generally drilled at the construction site or the countertop processing factory according to the size of the faucet and its accessories purchased or selected by the owner. The size of the installation hole needs to be able to allow the fixing plate and the two positioning seats that are brought together to pass through, but the base cannot pass through. At the construction site, the faucet is installed after the countertop is fixed. When installing the faucet, place the bolts and positioning rods vertically, then rotate the two positioning seats upward and bring them relatively close to each other, and then pass the fixing plate and the relatively close positioning seats through the installation holes of the countertop from top to bottom; when the relatively close positioning seats are completely passed through the installation holes, because the rod of the bolt and the positioning rod are inserted into the positioning piece, and the bolt and the positioning rod are arranged in parallel, the bolt and the positioning rod have a horizontal rotation limiting and movement limiting effect on the positioning piece. Under the action of gravity, the two positioning seats rotate downward smoothly and unfold under the action of gravity, and the two positioning seats are abutted against the fixing plate after unfolding, and the fixing plate is on the positioning piece. The seat forms an upward support; then hold the base and turn the bolt. Since the positioning rod and the bolt have a horizontal rotation limiting effect on the fixing plate, the fixing plate rises along the bolt as the bolt rotates, and the fixing plate drives the positioning seat to rise. Since the ends of the two positioning seats facing away from each other after unfolding protrude from the outer side surface of the fixing plate, the two unfolded positioning seats can abut against the lower surface of the countertop. After tightening the bolt, the countertop is clamped between the base and the positioning seat, that is, the faucet quick installation assembly is fixed on the countertop; finally, connect the faucet to the base to complete the installation of the faucet.

[0010] The two locating seats can smoothly rotate downward and unfold by their own gravity through the rotation limiting and movement limiting effects of the locating rod and the bolt in the horizontal direction and the upward supporting effect of the fixing plate, and then move upward to cooperate with the base to fix the faucet quick installation assembly on the countertop, making the faucet easy to install and stable. The two locating seats are unfolded by gravity, so there is no need to set a torsion spring between the two locating seats. In this way, during the installation process, the fingers do not need to overcome the elastic force of the torsion spring and press the two locating seats tightly, so that the fingers will not be hurt, which improves the comfort of the installation operation.

[0011] In the above-mentioned faucet quick installation assembly, the two positioning seats are in contact with each other at one end facing each other in the unfolded state, and the lower surfaces of the two positioning seats are both flat and flush. This arrangement can form a stable contact between the two positioning seats and the fixing plate after they are unfolded, so that the quick installation assembly can be stably installed on the countertop, which is conducive to reducing the possibility of shaking and loosening of the faucet after installation. In addition, the lower surfaces of the two positioning seats are both flat, which can also improve the comfort of operation when the fingers are pressed against the lower surfaces of the positioning seats when the two positioning seats are folded.

[0012] In the above-mentioned faucet quick installation assembly, avoidance holes are opened on the two positioning seats, the positioning rods and bolts are respectively inserted into the avoidance holes of the two positioning seats, and the hole walls of the two avoidance holes have openings on the sides close to each other.

[0013] The avoidance holes and openings have an avoidance function, which prevents the positioning rod and the bolt from interfering with the two positioning seats when they rotate upward and move closer together, so that the two positioning seats move closer together and can easily and smoothly pass through the mounting holes of the table top, avoiding the finger pain caused by the positioning piece being stuck in the mounting hole and needing to press down with the fingers, making the installation operation convenient and improving the operating comfort.

[0014] In the above-mentioned faucet quick installation assembly, a avoidance hole is provided on one of the positioning seats, the positioning rod and the bolt are both inserted into the avoidance hole, and the hole wall of the avoidance hole has an opening on one side close to the other positioning seat. The avoidance hole and the opening have an avoidance function, which prevents the positioning rod and the bolt from interfering with the positioning seat when it rotates upward, so that the two positioning seats are brought close to each other so that they can pass through the installation hole of the table easily and smoothly, avoiding the finger pain caused by the positioning piece being stuck in the installation hole and needing to be pressed down with the fingers, making the installation operation convenient and improving the comfort of the operation.

[0015] In the above-mentioned faucet quick installation assembly, the positioning member also includes a hinge shaft hinged between the two positioning seats, and the hinge shaft is located between the bolt and the positioning rod, or the bolt and the positioning rod are both inserted on the hinge shaft. The hinge shaft is located between the bolt and the positioning rod, which further enables the bolt and the positioning rod to limit the movement of the positioning member in the horizontal direction, and the bolt and the positioning rod are both inserted on the hinge shaft, which can also further enable the bolt and the positioning rod to limit the movement and rotation of the positioning member in the horizontal direction, so that the two positioning seats can smoothly abut against the fixing plate under the action of gravity, so that the faucet quick installation assembly is fixed and stable on the countertop.

[0016] In the above-mentioned faucet quick installation assembly, the upper surfaces of the two positioning seats are provided with installation grooves, and an elastic pad is fixed in each installation groove, and the upper end of each elastic pad protrudes from the upper surface of the corresponding positioning seat. When the bolt is tightened, the upper end of the elastic pad abuts against the lower surface of the table, and the elastic pad is compressed to form an elastic force, which can increase the friction between the positioning seat and the table, has a buffering and locking effect, and is conducive to reducing the shaking and loosening of the faucet after installation.

[0017] In the above-mentioned faucet quick installation assembly, a through hole is provided on the bottom surface of each installation groove, and a convex column is provided on the lower end surface of each elastic pad, and each convex column is inserted into and fixed in the corresponding through hole. The insertion of the convex column into the through hole fixes and stabilizes the elastic pad on the positioning seat, and prevents the elastic pad from moving when the positioning seat is folded.

[0018] In the above faucet quick installation assembly, the lower end of each boss extends out of the corresponding through hole, that is, the lower end of the boss protrudes from the lower surface of the positioning seat, which can improve the comfort of operation when the fingers are pressed against the elastic boss when closing the two positioning seats.

[0019] In the above-mentioned faucet quick installation assembly, the upper end surfaces of the two elastic pads are respectively provided with avoidance grooves for avoiding the bolts and the positioning rods. The avoidance grooves have an avoidance function, which prevents the elastic pads from interfering with the two positioning seats when they rotate upward and move closer together, and avoids finger pain caused by the need to press the elastic pads with fingers when the two positioning seats are closed, making the installation operation convenient and improving the comfort of the operation.

[0020] In the above-mentioned faucet quick installation assembly, a retaining ring is provided on the outer side surface of the base, and an external thread is provided on the base below the retaining ring. An internal thread that cooperates with the external thread can be provided on the hole wall surface of the countertop mounting hole. During installation, the base is inserted into the mounting hole of the countertop, and the external thread and the internal thread form a threaded connection. When the base is tightened, the retaining ring abuts against the upper surface of the countertop. At this time, the base is already fixed on the countertop, and then the bolts are tightened so that the positioning seat abuts against the lower surface of the countertop. The base is fixed first, and the base does not need to be held when tightening the bolts, so that the faucet quick installation assembly is easy to install on the countertop. In addition, the base is doubly fixed, which better avoids shaking and loosening of the faucet after installation.

[0021] Compared with the prior art, the utility model has the following advantages:
