Description

Technical Field

[0001] This utility model relates to the field of faucet technology, and more specifically, to an auxiliary wrench for installing faucets. Background Technology

[0002] A faucet is a common name for a water valve. It's a terminal control device in the tap water supply process, mainly used to control the water flow and on / off operation. Current faucet installation structures typically involve a connecting screw tube at the bottom of the faucet body. This tube extends from the mounting hole in the countertop to below the countertop. A nut is then screwed onto the connecting screw tube from below the sink. A sealing ring is fitted onto the connecting screw tube during connection. The faucet body is then secured to the mounting hole by screwing the nut upwards. Finally, a water inlet hose extends from the bottom of the connecting screw tube into the faucet body and screws onto the inlet hole. However, this installation method requires limited space under the countertop, making installation and disassembly inconvenient, and resulting in high maintenance costs.

[0003] Therefore, there is an urgent need to invent an auxiliary wrench for installing faucets. Utility Model Content

[0004] One of the objectives of this utility model is to provide an auxiliary wrench for installing faucets, which addresses the shortcomings of existing technologies. This auxiliary wrench can assist in the installation of faucets on the countertop and is compatible with various sizes of faucets. It is also convenient to use.

[0005] To solve the above-mentioned technical problems, this application adopts the following technical solution: providing an auxiliary wrench for installing a faucet, comprising: a limiting body, which is elongated, one end of the limiting body extending under the table through the mounting hole of the faucet mounting base, and the other end of the limiting body engaging with the mounting hole; an avoidance groove provided on the side of the limiting body along the length direction, and matching the fixing boss of the faucet mounting base; the cross-sectional area of ​​the limiting body gradually decreasing along the length direction.

[0006] Furthermore, the limiting end that contacts the locking member is matched in shape and size with the locking member, and the shape of the adapter end that is opposite to the limiting end is matched in shape with the shape of the mounting hole, and the size of the adapter end gradually decreases along the length direction of the limiting body from the bottom of the table to the top of the table.

[0007] Furthermore, the limiting body is provided with a protruding edge that protrudes outward along the circumference of the limiting body at one end of the table surface, and an observation hole is provided at the protruding edge corresponding to the avoidance groove.

[0008] Furthermore, it also includes a handle that is fixedly connected to the protruding edge.

[0009] Furthermore, the handle is parallel to the contact surface of the limiting end and the locking member.

[0010] Furthermore, the handle is provided with a through hole parallel to the length direction of the limiting body, and the shape of the through hole matches the shape of the filter element handle.

[0011] Furthermore, the through hole is located at the end of the handle away from the limiting body.

[0012] Furthermore, the end of the limiting body away from the handle is provided with a connector and a sleeve. The sleeve and the connector are shaped to match. The connector is provided with a receiving cavity. A spring and a snap fastener are provided in the receiving cavity. The spring abuts against the snap fastener under the action of elastic force. The snap fastener protrudes outside the connector through an exposure hole provided on the side wall of the connector and abuts against the inner wall of the sleeve to provide friction between the sleeve and the connector. The snap fastener is provided with a limiting protrusion to limit the distance of the snap fastener protruding from the through hole.

[0013] Furthermore, a spring cover is provided inside the receiving cavity. The spring cover has an arc-shaped support protrusion, and the support protrusion matches the shape of the spring buckle to limit the up and down movement of the spring buckle.

[0014] Furthermore, the connector is rectangular in shape.

[0015] The beneficial effects of this utility model are as follows: This application uses an auxiliary wrench to limit the locking block. When the threaded rod is rotated, the limiting end restricts the rotation of the locking block. The threaded rod drives the locking block to move towards the countertop until the locking block abuts against the underside of the countertop, thus locking the faucet mounting base. In this way, the installation of the faucet mounting base can be completed simply by rotating the threaded rod on the countertop, eliminating the need for installation under the countertop, which is convenient. Furthermore, since this application uses an auxiliary wrench to limit the locking block, the auxiliary wrench can be removed after installation without occupying space under the countertop or the space of the mounting hole, preventing interference. The auxiliary wrench of this application allows for efficient space utilization during the subsequent installation of hot and cold water pipes. Furthermore, because the cross-sectional area of ​​the limiting body gradually decreases along its length, it can effectively engage with mounting holes of varying cross-sectional areas. The relative movement of the fixed auxiliary wrench provides support to the limiting end. The gradually decreasing cross-sectional area of ​​the limiting body also facilitates entry and exit from mounting holes. The auxiliary wrench is reusable and requires no specific locking structure to limit the locking block. Therefore, the auxiliary wrench does not affect the vertical movement of the locking block, making installation more convenient. Attached Figure Description

Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application pertains. The terminology used in the specification of this application is for the purpose of describing specific embodiments only and is not intended to limit this application.

[0035] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0036] Although this application discloses preferred embodiments as described above, it is not intended to limit the claims. Any person skilled in the art can make several possible changes and modifications without departing from the concept of this application. Therefore, the scope of protection of this application should be determined by the scope defined in the claims of this application.

[0037] like Figure 1-6 As shown, an auxiliary wrench for installing a faucet is provided, comprising: a limiting body 1, which is elongated, one end of the limiting body 1 along its length can extend into the table under the table through the mounting hole 21 of the faucet mounting base 2, and the other end of the limiting body 1 along its length is engaged with the mounting hole 21; an avoidance groove 11 is provided on the side of the limiting body 1 along its length and matches the fixing boss 22 of the faucet mounting base 2; the cross-sectional area of ​​the limiting body 1 gradually decreases along its length.

[0038] To improve installation convenience by allowing faucets to be installed on the countertop without needing to access the under-counter area, existing faucets typically use a faucet mounting base 2 and a locking element 3 connected by a threaded rod. The faucet mounting base 2 is placed on the countertop, while the locking element 3 is placed under the countertop. By rotating the threaded rod on the countertop, the locking element 3 is limited in the direction of rotation. After rotation, the threaded rod moves the locking block towards the countertop until the locking element 3 abuts against the under-counter surface, thus locking the faucet mounting base 2. Some methods limit the locking element 3 by using a stop block on the faucet mounting base 2. However, this method occupies part of the mounting hole 21 of the faucet mounting base 2, making subsequent installation of hot and cold water pipes difficult. Other methods use auxiliary parts for limiting the locking element. However, existing auxiliary parts require interlocking with the locking block to achieve the limiting effect, and different faucet models require different auxiliary parts, which is inconvenient for installation and cumbersome to disassemble.

[0039] The auxiliary wrench of this application has a limiting body 1 with a gradually decreasing cross-sectional area along its length, and one end is engaged with the mounting hole 21. This allows the auxiliary wrench to be used with different sizes of faucets, with the limiting body 1 of different cross-sectional areas being securely engaged with the mounting hole 21. This ensures that there is a suitable limiting body 1 with a suitable cross-sectional area for engaging with different sizes of mounting holes 21, thus ensuring the stability of the auxiliary wrench. The auxiliary wrench can be used with mounting holes 21 of various sizes. The setting of the clearance groove 11 makes the engagement of the limiting body 1 with the faucet mounting base 2 more secure. Since the auxiliary wrench achieves its limiting function only by blocking the locking member 3, there is no need to engage the locking member 3 with the auxiliary wrench. Therefore, the disassembly of the auxiliary wrench is relatively simple.

[0040] The specific usage method is as follows: first insert the smaller end of the limiting body 1 into the mounting hole 21. When inserting into the mounting hole 21, ensure that the clearance groove 11 is aligned with the fixing boss 22 so that the clearance groove 11 locks the fixing boss 22, restricting the rotation of the auxiliary wrench in the mounting hole 21. As the limiting body 1 continues to extend, the gap between the mounting hole 21 and the limiting body 1 continuously decreases until the limiting body 1 is engaged with the mounting hole 21, thereby fixing the auxiliary wrench. At this time, rotate the threaded rod and the locking part 3 abuts against the limiting body 1 with the rotation of the threaded rod to limit the locking part 3. As the threaded rod rotates, it drives the locking part 3 to move, thereby locking.

[0041] Preferably, the limiting end 12 that contacts the locking member 3 is matched in shape and size with the locking member 3. The shape of the adapter end 13 that is opposite to the limiting end 12 is matched in shape with the shape of the mounting hole 21. The size of the adapter end 13 gradually decreases along the length direction of the limiting body 1 from the bottom of the table to the top of the table. By matching the shape and size of the limiting end 12 with the locking member 3, the limiting end 12 is more firmly positioned on the locking member 3 and is less likely to loosen. Preferably, the shape of the fixing boss 22 is set to be consistent with the shape of the locking member 3 facing the limiting end 12. At this time, the locking end 12 is more firmly engaged with the fixing boss 22. The adapter end 13 is used to realize the change of cross-sectional area to adapt to the size of different types of mounting holes 21 and provide stable fixation.

[0042] Preferably, the limiting body 1 is provided with a protruding edge 14 that protrudes outward along the circumference of the limiting body 1 at one end of the table surface, and an observation hole 17 is provided at the corresponding avoidance groove 11 of the protruding edge 14. The protruding edge 14 can abut against the edge of the faucet mounting seat 2, which is conducive to the disassembly of the wrench. The observation hole 17 is provided to provide space and observation position for the wrench to tighten the thread rod.

[0043] Preferably, it also includes a handle 4 fixedly connected to the protrusion 14. By setting the handle 4, the stability of the limiting body 1 can be increased by gripping the handle 4. The handle 4 is connected to the protrusion 14, which can disperse the force of the handle 4 on the limiting body 1 and improve stability. In some embodiments, the handle 4 is set to be hollow and the strength of the handle 4 is improved by setting reinforcing ribs. This setting can save materials and reduce the weight of the auxiliary wrench.

[0044] Preferably, the handle 4 is parallel to the contact surface between the limiting end 12 and the locking member 3. This arrangement ensures that the force direction of the limiting end 12 when the locking member 3 is limited and the force direction of the handle 4 when the handle is held are on the same straight line, which is beneficial for fixing the limiting body 1 with the handle 4.

[0045] like Figure 7-9 As shown, in some embodiments, the handle 4 is provided with a through hole 41 parallel to the length direction of the limiting body 1. The shape of the through hole 41 matches the shape of the filter handle 4. With this setting, the through hole 41 can be snapped into the filter handle 4, and the filter can be disassembled by rotating the handle 4. The auxiliary wrench of this application is L-shaped. When it is necessary to rotate the handle 4, the limiting body 1 can also be used as a force point to grip the limiting body 1 and provide the power for rotating the handle 4, which can effectively improve the efficiency of disassembling the filter. This application can remove the filter from the water purifier and also remove the filter cover.

[0046] Preferably, the through hole 41 is located at the end of the handle 4 away from the limiting body 1, increasing the distance between the through hole 41 and the limiting body 1 to increase the lever arm and reduce the force required to disassemble the filter element, making it easier to disassemble the filter element.

[0047] As shown in Figures 10-16, in some embodiments, the end of the limiting body 1 away from the handle 4 is provided with a connector 15 and a sleeve 16. The sleeve 16 and the connector 15 are matched in shape. The connector 15 is provided with a receiving cavity 151. The receiving cavity 151 is provided with a spring buckle 1511 and a spring 1512. The spring 1512 abuts against the spring buckle 1511 under the action of elastic force. The spring buckle 1511 protrudes outside the connector 15 through the protrusion hole 1514 provided on the side wall of the connector 15 and abuts against the inner wall of the sleeve 16 to provide friction between the sleeve 16 and the connector 15. The spring buckle 1511 is provided with a limiting protrusion 15111 to limit the distance of the spring buckle 1511 protruding from the through hole 41. The limiting protrusion 15111 can lock the wall near the protrusion hole 1514 when the spring buckle 1511 protrudes from the protrusion hole 1514 to prevent the spring buckle 1511 from being lost.

[0048] This design allows the spring clip 1511 to protrude from the protrusion hole 1514 and press against the inner wall of the sleeve 16 when the sleeve 16 is inserted into the connector 15, providing friction between the sleeve 16 and the connector 15. This prevents the sleeve 16 from loosening and falling off the connector 15. When it is necessary to disassemble the sleeve 16, only a force greater than the friction between the sleeve 16 and the connector 15 is needed to pull the sleeve 16 out. Disassembly and installation of the sleeve 16 are very convenient. This application improves the utilization rate of the auxiliary wrench through this design, and its multi-functional design allows one auxiliary wrench to complete the entire process of installing and disassembling the water purifier, saving materials and being easy to use.

[0049] Preferably, a spring cover 1513 is also provided inside the receiving cavity 151. The spring cover 1513 is provided with an arc-shaped support protrusion 15131, and the support protrusion 15131 matches the shape of the spring buckle 1511. This is used to restrict the up and down movement of the spring buckle 1511, so that the spring buckle 1511 can only move back and forth along the axial direction of the exposed hole 1514, making the extension and retraction of the spring 1512 smoother and facilitating the disassembly and assembly of the sleeve 16 connector 15. Preferably, the limiting body 1 can be made hollow, and the spring cover 1513 can be inserted into the receiving cavity 151 of the connector 15 through the hollow opening of the limiting body 1. After the spring cover 1513 is closed on the opening of the receiving cavity 151, the spring cover 1513 is glued to the wall of the limiting body 1 with adhesive. In this way, the replacement of parts inside the receiving cavity 151 becomes easier.

[0050] Preferably, the shape of the connector 15 is rectangular. The rectangular shape can match most sockets 16 on the market, which improves the applicability of the auxiliary wrench. Moreover, setting it to a rectangle is more conducive to the transmission of force between the connector 15 and the socket 16, thus improving practicality.

[0051] The foregoing description illustrates and describes several preferred embodiments of the present invention. However, as previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the present invention's conception through the foregoing teachings or related technical or knowledge. Any modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention should be protected within the scope of the appended claims.
