Description

Technical Field

[0001] This utility model relates to the field of faucet fastening device technology, and in particular to a fastening device and faucet. Background Technology

[0002] Currently, the most common faucet installation methods on the market are divided into two types: countertop installation and under-counter installation. Under-counter installation is particularly inconvenient when space is limited, as the space under the counter is usually quite small, making the installation process complex and time-consuming, and also increasing labor intensity. While countertop installation avoids the space limitations of under-counter installation, it requires the installation of a special fixing device. Common fixing devices have relatively complex structures, high production costs, and their applicability is easily limited. Utility Model Content

[0003] This utility model provides a fastening device and faucet that avoids under-counter installation, while reducing the complexity of on-counter installation and lowering production costs, thereby expanding the scope of application.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A fastening device, comprising:

[0006] A fixing sleeve has a first limiting part at its bottom and a receiving channel extending through it along its axial direction. The outer side of the fixing sleeve has a notch communicating with the receiving channel. By controlling the opening size of the notch, the cross-sectional area of ​​the fixing sleeve is changed, allowing it to pass through the mounting hole on the table surface; and...

[0007] The fastener has a portion located inside the receiving channel and another portion located outside the fixing sleeve, such that when the fastener is connected to the fixing sleeve, a portion of the fastener can open the fixing sleeve, allowing the fixing sleeve to connect to the other portion of the fastener. When the fixing sleeve is opened, the minimum radial dimension of the first limiting portion is greater than the maximum radial dimension of the mounting hole, allowing the first limiting portion to abut against the lower end face of the table.

[0008] Furthermore, when the fastener expands the fixing sleeve, there is a gap between the fixing sleeve and the mounting hole.

[0009] Furthermore, the fasteners include:

[0010] The fixing sleeve has a receiving channel that runs through it along its axis. The outer side of the fixing sleeve has a notch that connects to the receiving channel. By controlling the opening size of the notch, the cross-sectional area of ​​the fixing sleeve can be changed so that it can be installed in the mounting hole on the table.

[0011] The resetting member has a through-channel extending along its axial direction. The resetting member is installed within the receiving channel to expand the fixing sleeve, so that the fixing sleeve fits into the mounting hole; and...

[0012] The locking component is partially connected to the retaining sleeve to secure the retaining sleeve to the countertop, while the other part of the locking component is used to connect to the faucet body.

[0013] Furthermore, the outer side of the reset member is provided with a protrusion arranged along its axial direction. When the reset member is inserted into the receiving channel, the protrusion is located at the notch, and the outer side of the reset member away from the fixed sleeve is provided with a second limiting part. The second limiting part extends outward along the radial direction of the reset member and abuts against the end face of the fixed sleeve.

[0014] Furthermore, the locking element and the second limiting part have anti-slip textures on the side that abuts against the table surface.

[0015] Furthermore, the fixed sleeve at one end of the upper part of the table and the locking element are respectively provided with locking positions for connecting tools to drive the fixed sleeve and the locking element to move relative to each other and lock them together.

[0016] A faucet includes a faucet body and a fastening device as described above, the faucet body being connected to a locking element.

[0017] Furthermore, the outer side of the locking component is provided with external threads, and the inner side of the faucet body is provided with internal threads. The external threads and internal threads are connected to each other by threaded locking.

[0018] Furthermore, one of the faucet body and the locking component is provided with a fixing hole, and the other is provided with a retractable fixing pin; when the faucet body is connected to the locking component, the fixing pin is engaged with the fixing hole.

[0019] Furthermore, the outer side of the locking element is provided with an abutting surface for abutting against the inner wall of the faucet body.

[0020] The beneficial effects of this utility model are:

[0021] 1. This utility model proposes a fastening device that, compared to common countertop mounting devices, comprises only a fixing sleeve and a fixing member. Part of the fixing member is located within the receiving channel, while the other part is located outside the fixing sleeve. When the fixing member is connected to the fixing sleeve, part of the fixing member expands the fixing sleeve, allowing the fixing sleeve to connect to the other part of the fixing member, thereby securing the fixing sleeve to the countertop. The fixing member also serves to connect to the faucet body. Therefore, this fastening device reduces the complexity of countertop mounting devices, lowers production costs, and expands its applicability.

[0022] 2. The fastening device proposed in this utility model has a gap between the fixing sleeve and the mounting hole when the fixing member opens the fixing sleeve, so as to avoid the need for a large force to insert the fixing member into the fixing sleeve due to the fixing sleeve being too large to fit the mounting hole, thus ensuring the ease of installation of the fixing member.

[0023] 3. The fastening device proposed in this utility model has a protrusion on the outer side of the reset member arranged along its axial direction. When the reset member is inserted into the receiving channel, the protrusion is located at the notch, controlling the opening of the notch to ensure a tight connection between the outer side of the fixing sleeve and the locking member.

[0024] 4. The fastening device proposed in this utility model has a first limiting part on the outer side of the reset member away from the fixed sleeve. The first limiting part abuts against the end face of the fixed sleeve to prevent the reset member from falling out of the fixed sleeve and to avoid the lack of support inside the fixed sleeve, which would result in a tight connection between the outer side of the fixed sleeve and the locking member.

[0025] 5. The present invention provides a fastening device in which a second limiting part is provided on the outer side of the end of the fixing sleeve located below the table surface. After the fixing sleeve is opened, the second limiting part abuts against the lower end surface of the table surface, thereby preventing the fixing sleeve from being pulled out from the upper end of the table surface during use.

[0026] 6. The fastening device proposed in this utility model has anti-slip texture on the side of the locking member and the second limiting part that abuts against the table surface, so as to increase the friction between the locking member and the second limiting part and the table surface and reduce the loosening caused by the rotation of the locking member and the fixing sleeve relative to the table surface.

[0027] 7. The fastening device proposed in this utility model has a locking position at one end of the fixing sleeve located on the upper part of the table and a locking member, which facilitates the connection tool to drive the fixing sleeve and the locking member to move relative to each other and lock them together. At the same time, the angle position of the locking member can be pre-adjusted through the locking position to ensure that the water outlet direction is correct after the faucet is installed.

[0028] 8. The present invention proposes a faucet, including a faucet body, which is connected to a locking component. The connection between the faucet body and the locking component can be a threaded connection or a pin connection. The threaded connection is reliable and stable, while the pin connection is convenient and quick.

[0029] 9. The present invention proposes a faucet in which, when the faucet body and the locking member are connected by a pin, the outer side of the locking member is provided with an abutting surface for abutting against the inner side wall of the faucet body to reduce the wobbling of the faucet body in the radial direction.

Detailed Implementation

[0039] Example 1

[0040] A fastening device includes a fixing sleeve 10 and a fastener, specifically,

[0041] The fixing sleeve 10 has a first limiting part 401 at its bottom and a receiving channel 101 extending through it along its axial direction. The outer side of the fixing sleeve 10 has a notch 102 communicating with the receiving channel 101. By controlling the opening size of the notch 102, the cross-sectional area of ​​the fixing sleeve 10 is changed, allowing it to pass through the mounting hole 100 of the tabletop 90; and...

[0042] The fastener is partially located within the receiving channel 101, while the other part is located outside the fixing sleeve 10. This allows the fastener to partially open the fixing sleeve 10 when connected to it, thus connecting the fixing sleeve 10 to the other part of the fastener. When the fixing sleeve 10 is open, the minimum radial dimension of the first limiting part 401 is greater than the maximum radial dimension of the mounting hole 100, allowing the first limiting part 401 to abut against the lower end face of the tabletop 90, preventing the fixing sleeve 10 from being pulled out from the upper end of the tabletop 90 during use.

[0043] Compared to common countertop mounting devices, this fastening device only includes a fixing sleeve 10 and a fastener. When the fastener is connected to the fixing sleeve 10, a portion of the fastener expands the fixing sleeve 10, allowing the fixing sleeve 10 to connect to another portion of the fastener, thus fixing the fixing sleeve 10 to the countertop 90. The fastener also serves to connect the faucet body 60. Therefore, this fastening device reduces the complexity of countertop mounting devices, lowers production costs, and expands its applicability.

[0044] During installation, when the fastener opens the fixing sleeve 10, there is a gap 110 between the fixing sleeve 10 and the mounting hole 100. This avoids the need for a large force to insert the fastener into the fixing sleeve 10 due to the fixing sleeve 10 being too close to the mounting hole 100, thus ensuring the ease of installation of the fastener.

[0045] In this embodiment, the fixing member includes a separate reset member 20 and a locking member 30. In other embodiments, the reset member 20 and the locking member 30 may be integrally formed. The reset member 20 has a through channel 201 extending through it along its axial direction. The reset member 20 is installed in the receiving channel 101 to expand the fixing sleeve 10, so that the fixing sleeve 10 fits the mounting hole 100. The locking member 30 is partially connected to the fixing sleeve 10, thereby fixing the fixing sleeve 10 to the countertop 90, and the other part of the locking member 30 is used to connect to the faucet body 60.

[0046] In this embodiment, as Figure 1 As shown, the outer side of the reset member 20 has a protrusion 202 arranged along its axial direction. When the reset member 20 is inserted into the receiving channel 101, the protrusion 202 is located at the notch 102, controlling the opening of the notch 102 to ensure a tight connection between the outer side of the fixing sleeve 10 and the locking member 30. Further, as... Figure 1 As shown, a second limiting part 402 is provided on the outer side of the reset member 20 away from the fixed sleeve 10. The second limiting part 402 extends radially outward along the reset member 20 and abuts against the end face of the fixed sleeve 10 to prevent the reset member 20 from falling out of the fixed sleeve 10 and to avoid the lack of support inside the fixed sleeve 10, which would result in a lack of tight connection between the outer side of the fixed sleeve 10 and the locking member 30.

[0047] The locking member 30 and the second limiting part 402 are provided with anti-slip texture on the side that abuts against the table surface 90 to increase the friction between the locking member 30 and the second limiting part 402 and the table surface 90, and reduce the loosening caused by the rotation of the locking member 30 and the fixing sleeve 10 relative to the table surface 90.

[0048] In this embodiment, the fixed platform and the locking member 30 are connected by threads. The fixed sleeve 10 at one end of the platform 90 and the locking member 30 are each provided with a locking position 50, used to connect tools to drive the fixed sleeve 10 and the locking member 30 to move relative to each other and thus lock them together. Specifically, the locking position 50 is hexagonal, facilitating engagement with a hexagonal wrench. The locking position 50 allows for pre-adjustment of the angle of the locking member 30, ensuring the correct water flow direction after the faucet is installed.

[0049] The installation process of the fastening device proposed in this embodiment is as follows.

[0050] S1. The notch 102 is reduced by radial compression along the fixed sleeve 10, which reduces the cross-sectional area of ​​the fixed sleeve 10 so that it can pass through the mounting hole 100 of the table 90.

[0051] S2. Insert the reset piece 20 into the receiving channel 101 of the fixed sleeve 10, and the protrusion 202 cooperates with the notch 102 to open the fixed sleeve 10 so that it fits the mounting hole 100.

[0052] S3. Next, screw the locking member 30 to the outside of the fixing sleeve 10 until the locking member 30 and the second limiting part 402 abut against the table surface 90 to complete the installation.

[0053] Example 2

[0054] A type of faucet, such as Figures 2 to 4 As shown, it includes a faucet body 60 and a fastening device as described above, the faucet body 60 being connected to the locking member 30. Further, as... Figure 4 As shown, the outer side of the locking member 30 has an external thread, and the inner side of the faucet body 60 has an internal thread. Through the threaded engagement between the external and internal threads, the faucet body 60 is connected to the locking member 30, thereby connecting the faucet body 60 to the countertop 90. The cold water inlet pipe 702 and the hot water inlet pipe 701 are connected to the mixing valve located inside the faucet body 60 via the through-channel 201.

[0055] Example 3

[0056] The difference between this embodiment and Embodiment 2 is that the faucet body 60 and the locking member 30 are detachably connected by a pin. Specifically, the outer side of the locking member 30 is provided with a mounting groove 301, and a spring 802 and a fixing pin 801 are provided in the mounting groove 301. One end of the spring 802 abuts against the mounting groove 301, and the other end abuts against the fixing pin 801, so that the fixing pin 801 can extend and retract under the elastic force of the spring 802. The inner side of the faucet body 60 is provided with a fixing hole 601. When the faucet body 60 is connected to the locking member 30, the fixing pin 801 is engaged with the fixing hole 601.

[0057] In this embodiment, the radial dimension of the fixing pin 801 gradually decreases along the direction in which it is inserted into the fixing hole 601, such that a portion of the fixing pin 801 is located inside the fixing hole 601 and another portion of the fixing pin 801 is located outside the fixing hole 601, preventing the fixing pin 801 from falling out of the fixing hole 601 under the action of elasticity. Figure 6 As shown. Specifically, the fixing pin 801 includes an insertion section 8011 and a limiting section 8012 located at the end of the insertion section 8011 away from the fixing hole 601. The radial dimension of the insertion section 8011 is not greater than the radial dimension of the fixing hole 601, and the radial dimension of the limiting section 8012 is greater than the fixed radial dimension. In other embodiments, the radial dimension of the fixing hole 601 gradually decreases along the insertion direction of the fixing pin 801, so that the minimum radial dimension of the fixing hole 601 is smaller than the radial dimension of the fixing pin 801, which can also prevent the fixing pin 801 from falling out of the fixing hole 601 under the action of elastic force.

[0058] When it is necessary to remove the faucet body 60, press the fixing pin 801 through the fixing hole 601 to disengage it from the fixing hole 601, and then pull the faucet body 60 upward to remove it. In other embodiments, the mounting groove 301 may also be provided on the inner side of the faucet body 60, and the fixing hole 601 may be provided on the outer side of the locking member 30. The installation and disassembly process is the same as described above.

[0059] In this embodiment, as Figure 7 As shown, the outer side of the locking member 30 is provided with an abutting surface, which is used to abut against the inner side wall of the faucet body 60 to reduce the wobbling of the faucet body 60 in the radial direction and maintain the stability of the faucet body 60.

[0060] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the scope of protection of this utility model.
