Description

Technical Field

[0001] The invention relates to the technical field of faucets, and in particular to an expansion type faucet fixing seat. Background Art

[0002] A faucet fixing seat is a device for fixing the faucet to a mounting surface. Usually, a connecting hole is set on the outer wall of the faucet fixing seat. The faucet fixing seat is first fixed in the mounting hole on the mounting surface, and then the faucet is put on the faucet fixing seat. A through hole is set at the position corresponding to the connecting hole on the faucet, and bolts are connected to the bolt holes through the through holes to connect the faucet and the faucet fixing seat. However, this way of connecting the outer wall of the faucet fixing seat and the inner wall of the faucet is usually set to a clearance fit, otherwise it will not be able to be inserted. In this way, the faucet may shake after connection and is not firm enough. Summary of the invention

[0003] In summary, in order to overcome the deficiencies of the prior art, the present invention provides an expandable faucet fixing seat which expands and fits the inner wall of the faucet after being put on the faucet to make the connection more secure.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an expandable faucet fixing seat, comprising a fixing sleeve and a mounting device, the mounting device is used to install the fixing sleeve on a mounting surface, a connecting block is provided inside the fixing sleeve, an expansion groove is provided on the outer wall of the fixing sleeve, the width of the connecting block is greater than the width of the expansion groove, the connecting block is provided with a connecting hole, and when the connecting block moves toward the expansion groove, the fixing sleeve is stretched out from the position of the expansion groove.

[0005] With such an arrangement, during installation, the fixing sleeve is first fixed to the mounting hole position on the mounting surface with the installation device, and then the faucet is put on the outside of the fixing sleeve that matches the gap with it, and the connecting bolt is passed through the hole on the outer wall of the faucet to connect it to the connecting block. The connecting hole can be set as a threaded hole, so that the connecting bolt can be directly screwed into the connecting hole, or the connecting bolt can be passed through the connecting hole and then connected with a nut. At this time, the connecting bolt is continuously screwed into the connecting block and will continuously move toward the expansion groove until the connecting block contacts the expansion groove, and the fixing sleeve is stretched from here. At this time, the outer wall of the fixing sleeve will be expanded and close to the inner wall of the faucet to enter a state similar to an interference fit. The outer wall of the fixing sleeve fits tightly with the inner wall of the faucet without any gap, and the connection is more firm and more stable.

[0006] Furthermore, inclined surfaces are provided on both sides of the expansion groove or both sides of the connection block, or both sides of the expansion groove and the connection block are provided with inclined surfaces.

[0007] In this arrangement, inclined surfaces are provided on both sides of the expansion slot or on both sides of the connection block, or both are provided with inclined surfaces. When the connection block moves toward the expansion slot, it will expand the fixing sleeve along the inclined surfaces, making it easier to expand.

[0008] Furthermore, baffles are provided on both sides of the connecting block.

[0009] With such arrangement, the baffles on both sides will block the connection block, so that it is always located in the fixing sleeve and will not be pulled out to cause disconnection from the expansion groove, thereby affecting the expansion state of the fixing sleeve.

[0010] Furthermore, the connecting block is integrally arranged with the fixing sleeve, and a movable groove is provided between the baffle and the inner wall of the fixing sleeve.

[0011] With this arrangement, after the connecting block and the fixing sleeve are integrally arranged, when the fixing sleeve is stretched open and interference fits with the inner wall of the faucet, the connecting hole can also simultaneously limit the vertical movement of the faucet, making the connection more firm and stable. When the connecting bolt is screwed into the connecting block, the connecting block will move toward the movable groove and will not be blocked.

[0012] Furthermore, a main auxiliary bending groove is provided at the connection between the baffle and the fixing sleeve.

[0013] With such arrangement, the connecting block is easier to bend after the main bending-assisting grooves are arranged on both sides.

[0014] Furthermore, an auxiliary bending-assisting groove is provided at the connection between the baffle and the connecting block.

[0015] With this arrangement, the connecting block is easier to bend after auxiliary bending-assisting grooves are arranged on both sides.

[0016] Furthermore, the opening direction of the auxiliary bending-assisting groove is opposite to the opening direction of the main bending-assisting groove.

[0017] With such arrangement, the rear baffle is easier to maintain a vertical state after the main bending-assisting groove and the auxiliary bending-assisting groove are arranged oppositely, and is easier to fit the expansion groove to stretch it open.

[0018] Furthermore, the thickness of the connecting block is greater than the thickness of the baffle.

[0019] With this arrangement, if the connecting hole is not a bolt hole, the thickness of the connecting block can be increased to increase its thread length, making the connection more stable, or a nut groove can be set on the top surface of the connecting block, the nut is placed in the nut groove and then the connecting bolt is passed through the connecting hole to connect with the nut in the nut groove, which is convenient for installation.

[0020] Furthermore, the mounting device comprises a mounting plate, the mounting plate is provided with a mounting hole, the inner wall of the fixing sleeve is provided with a mounting block, and the mounting block is provided with a plug-in hole adapted to the mounting hole.

[0021] With this arrangement, the mounting hole can be arranged as a threaded hole, and a long bolt can be passed through the plug-in hole to directly connect with the mounting hole on the mounting plate, or the long bolt can be passed through the mounting hole and connected with a nut. During installation, the mounting plate can be placed obliquely into the mounting hole on the mounting surface, and then the long bolt can be tightened to make the mounting plate continuously move toward the fixing sleeve until the mounting surface is clamped. In this way, the fixing sleeve can be directly installed on the mounting surface above the mounting surface. The installation is convenient, and multiple mounting blocks and mounting holes can be arranged.

[0022] Furthermore, a positioning piece is provided on a side of the fixing sleeve facing the mounting piece, and the mounting piece is provided with a positioning groove adapted to the positioning piece.

[0023] With this arrangement, during installation, the positioning groove can be inserted into the position of the positioning piece first. At this time, the mounting hole will be coaxial with the plug-in hole. The long bolt can be directly inserted when it is screwed in without deliberate alignment. After the long bolt and the mounting piece are connected, it can be pushed out and inserted into the mounting hole of the mounting surface. Two positioning pieces can be set.
