[0030] From the above description of the present invention and its preferred embodiments, it can be seen that compared with the prior art, the technical solution of the present invention and its preferred embodiments have the following beneficial effects due to the adoption of the following technical means:

[0031] 1. In solution 1 and its preferred embodiment, a mounting mechanism is suitable for being mounted on the pipe portion of a faucet located below a countertop, and includes a base and a clamping mechanism.

[0032] The base has a through hole for the pipe portion to pass through;

[0033] The clamping mechanism includes a clamping member, a pressing member and a force applying member.

[0034] The clamping member is used to clamp the pipe portion, which is operably movable and is arranged on the base in a locked posture and an unlocked posture. In the unlocked posture, the clamping member is supported away from the pipe portion so that the through hole can be operably inserted into the pipe portion from bottom to top, so that the pipe portion can be installed; in the locked posture, the clamping member is supported to contact the pipe portion to prevent the pipe portion from moving upward relative to the base. Therefore, when the faucet moves upward, the clamping member will tend to move upward.

[0035] The pressing member is operatively movable and supported on the base in a manner of generating displacement in an up-down direction during the movement, and the pressing member is used to abut against the lower surface of the table top;

[0036] During the process of inserting the installation mechanism into the pipe from bottom to top, the clamping member first clamps the pipe. Through this action, the installation mechanism is supported on the pipe and will not fall off, thereby forming a locking posture. In this locking posture, the installation mechanism only realizes the insertion into the pipe and the locked position of the pipe, and does not provide a locking force to completely fix the faucet. Therefore, the entire upward insertion process does not require the user to provide any strength.

[0037] The force-applying portion is configured to apply force to the pressing member when the clamping member is in a locked position and receives a downward force, causing the pressing member to move upward and press against the lower surface of the countertop. During the pressing process, the force exerted by the pressing member on the base is applied to the clamping member supported on the base, causing the clamping member to press against the pipe portion of the faucet, thereby locking the faucet to the countertop through the clamping member and the pressing member. The force-applying portion is configured to be movable in response to the downward force. Therefore, during installation, based on the locked position of the clamping member, the operator does not need to push upward in the invisible and narrow installation space under the countertop. Instead, the operator only needs to move downward along the natural state of the arm to provide the force-applying portion with a movable force, thereby providing the pressing member with a locking force to lock the faucet to the countertop, thereby achieving both the stability of the faucet installed on the countertop and the easy blind installation under the countertop.

[0064] refer to Figure 1A mounting mechanism is provided, adapted to be mounted on the tube portion 601 of a faucet 60 located below a countertop 20. The countertop 20 is provided with a through hole 201 extending in the vertical direction. The faucet 60 includes a tube portion 601 and a raised ring 602 that protrudes radially outward from the tube portion 601. The raised ring 602 is adapted to seat above the countertop 20 when the tube portion 601 passes through the through hole 201 and is located below the countertop 20, thereby preventing the faucet 60 from moving downward. The mounting mechanism is adapted to be mounted on the tube portion 601 of the faucet 60 located below the countertop 20, thereby preventing the faucet 60 from moving upward. Of course, in other embodiments, the mounting mechanism can also be used for installation in other similar environments, and is not limited to faucet 60 products or vertical installation. The following uses the installation of the faucet 60 on the countertop 20 as an example.

[0065] Example 1

[0066] refer to Figures 1-8 The installation mechanism includes a base 1 and a clamping mechanism.

[0067] refer to Figure 2 The base 1 has a through hole 11 for the pipe portion 601 to partially pass through. The through hole 11 is located in the middle of the base 1 and extends in the up and down direction. Figure 2 The base 1 is also provided with a first sliding hole 12, which extends in a direction perpendicular to the up-down direction, and the inner side of the first sliding hole 12 is connected to the through hole 11. The base 1 is provided with an upward supporting surface 13 and a partition wall 14 protruding from the supporting surface 13. The partition wall 14 divides the space inside the base 1 into a first mounting cavity 15 and a second mounting cavity 16, wherein the first mounting cavity 15 is connected to the outer side of the first sliding hole 12 (the end away from the through hole 11). The tops of the first mounting cavity 15 and the second mounting cavity 16 are both connected to the upper opening of the base 1. The second mounting cavity 16 also has a side opening on the side away from the first mounting cavity 15.

[0068] The clamping mechanism includes a clamping member 2 , a pressing member 30 , a clamping drive member 4 , a force applying portion 50 , a first biasing member 6 , a locking member 7 , and a first pressing member 8 .

[0069] refer to Figure 2 、 Figure 3, the number of the clamping members 2 is at least two, and at least two clamping members 2 hold the tube portion 601 in a locked position, thereby achieving a better holding effect. Of course, when there is only one clamping member 2, the holding effect can also be achieved, such as the clamping member 2 and the hole wall of the through hole 11 holding the tube portion 601 together. The clamping member 2 is operably movable and is arranged on the base 1 in a locked position and an unlocked position. Herein, operably movable means that it is movable under the drive of an external force, including direct operation (force directly acts on the clamping member 2) and indirect operation (force indirectly acts on the clamping member 2). In this embodiment, the clamping member 2 is located in the first mounting cavity 15 and is seated on the support surface 13, and is suitable for sliding cooperation with the first sliding hole 12. The clamping member 2 is suitable for abutting against the tube portion 601, and has a protrusion (a corresponding groove on the tube portion 601), a groove (a corresponding protrusion on the tube portion 601), teeth (a corresponding tooth on the tube portion 601), etc. on the surface thereof that is suitable for abutting against the tube portion 601. In this embodiment, the clamping member 2 has teeth on the surface thereof that is suitable for abutting against the tube portion 601.

[0070] refer to Figure 3 , the clamping member 2 is in the unlocked position, the clamping member 2 is supported away from the tube 601 and is located in the first sliding hole 12, so that the through hole 11 can be operatively inserted into the tube 601 from bottom to top; Figure 4 In the locked posture, the clamping member 2 extends from the first sliding hole 12 and into the through hole 11, and is supported to contact the tube portion 601. At this time, the clamping member 2 prevents the base 1 from moving downward relative to the tube portion 601 through tooth matching or concave-convex matching (grooves, protrusions) or friction (tight contact).

[0071] refer to Figure 3 、 Figure 4 The clamping drive member 4 is supported on the base 1 in a movable manner relative to the base 1. In this embodiment, the clamping drive member 4 is slidably connected to the first mounting cavity 15 of the base 1 along the up and down directions. The clamping drive member 4 has a clamping force receiving portion 41 and a pushing portion 42. The clamping force receiving portion 41 initially protrudes from the upper opening of the base 1 so that it is pushed by the lower surface of the table 20 during the process of the base 1 being inserted into the tube portion 601 from bottom to top, thereby moving downward. One of the pushing portion 42 and the clamping member 2 has an inclined groove 21, and the other has an inclined block 421 suitable for inserting into the inclined groove 21. The inclined groove 21 extends in a direction away from the through hole 11 and is inclined downward. Through the cooperation of the pushing portion 42 with the inclined surface of the clamping member 2, the pushing portion 42 pushes the clamping member 2 from the unlocking posture to the locking posture during the downward movement of the pushing portion 42. The inclined surface cooperation means that at least one of the two has an inclined surface or a curved surface, so that the direction of the force changes.

[0072] refer to Figure 3 、 Figure 4, and the two ends of the first biasing member 6 act on the base 1 and the clamping drive member 4 respectively to apply an upward force to the clamping drive member 4; specifically, the upper end of the first biasing member 6 abuts against the clamping drive member 4, and the lower end abuts against the base 1, so that the above-mentioned action can be achieved. When unlocking is required, the first biasing member 6 will drive the clamping drive member 4 to move upward. Since one of the pushing portion 42 and the clamping member 2 has an inclined groove 21, and the other has an inclined block 421 suitable for inserting into the inclined groove 21, and the inclined groove 21 has two opposing inclined surfaces, under the cooperation of such inclined surfaces, when the clamping drive member 4 resets upward, it will also apply force to the clamping member 2, thereby causing the clamping member 2 to slide toward the unlocking position until the clamping member 2 abuts against the partition wall 14. At this time, the clamping member 2 is in the unlocking position and stops sliding.

[0073] Of course, in other embodiments, the two ends of the first biasing member 6 may also act on the base 1 and the clamping member 2 respectively, and are suitable for applying a force to the clamping member 2 to move it toward the unlocked position. Since the clamping drive member 4 can only move up and down, under the action of the inclined groove 21 and the inclined block 421, the clamping drive member 4 will be driven by the clamping member 2 to move upward. Of course, in this embodiment, only one of the clamping member 2 and the clamping drive member 4 can have an inclined surface, that is, the inclined surface does not need to cooperate with the inclined groove 21 and the inclined block 421 to achieve linkage.

[0074] refer to Figure 3 、 Figure 4 The pressing member 30 is operable to move and is supported on the base 1 in a manner that produces displacement in the up and down directions during the movement. Specifically, a guide slope is provided on the base 1, and the guide slope is configured to gradually tilt upward along the direction of movement of the pressing member 30 when the force is applied by the force-applying portion 50. In this embodiment, the guide slope extends in the direction close to the through hole 11 and tilts upward so that the pressing member 30 can slide upward when the force-applying portion 50 presses down. The pressing member 30 is located on the guide slope, and the pressing member 30 is provided with a force-bearing slope 31, which extends in the direction away from the through hole 11 and tilts downward. Reference Figure 7 In other embodiments, an intermediate block 40 may also be provided, and the pressing member 30 and the intermediate block 40 constitute the pressing member 3. The intermediate block 40 cooperates with the pressing member 30 through an upwardly inclined inclined surface, so that the pressing member 30 moves upward when the intermediate block 40 slides; for example, the force-applying portion 50 cooperates with the inclined surface of the intermediate block 40, so that when the force-applying portion 50 applies a downward force to the intermediate block 40, the intermediate block 40 slides horizontally, and the intermediate block 40 cooperates with the inclined surface of the pressing member 30, so that the pressing member 30 slides upward when the intermediate block 40 slides. The resetting of the pressing member 30, i.e., downward movement, can be achieved by providing an elastic member, with both ends of the elastic member acting on the pressing member 30 and the base 1, thereby achieving its downward movement and resetting, or by self-resetting.

[0075] In an exemplary embodiment, the guide slope extends in a circumferential direction around the tube portion 601, and the force-bearing slope 31 intersects this extension direction, allowing the pressing member 30 to slide diagonally upward along the circumferential direction. Exemplarily, the intermediate block 40 is supported on the base 1 in a manner that allows it to slide in a circumferential direction around the tube portion 601.

[0076] refer to Figure 3 、 Figure 4 、 Figure 5 The force-applying portion 50 constitutes a force-applying member 5, which is constructed as an annular sleeve that is easy for the user to grasp. The force-applying member 5 is sleeved on the outside of the base 1 and blocks the side opening of the second installation cavity 16 away from the first installation cavity 15, thereby forming an installation space between the base 1, and the installation space is suitable for the arrangement of the clamping member 2 and the pressing member 30.

[0077] The force-applying portion 50 is configured to receive a downward force and apply force to the pressing member 30 when the clamping member 2 is in a locked position, so that the pressing member 30 is displaced upward and pressed against the lower surface of the table 20, thereby forming a force applied to the clamping member 2 toward the tube portion 601. The force-applying portion 50 is movably supported on the base 1. In this embodiment, the force-applying portion 50 is adapted to be slidably connected to the base 1 up and down. In this embodiment, the upper end of the force-applying portion 50 has an inclined surface identical to the force-bearing inclined surface 31, so as to cooperate with the inclined surface of the force-bearing inclined surface 31 of the pressing member 30, so that when force is applied to the pressing member 30, the pressing member 30 slides in an obliquely upward direction on the guide inclined surface. Since the pressing member 30 is supported by the guide slope, it presses against the lower surface of the table 20 and continues to move upward, which causes the base 1 to move downward, causing the clamping member 2 to move downward to eliminate the corresponding matching gap (such as the upper and lower gaps between the teeth) and make the clamping member 2 press downward against the tube 601 to increase the corresponding friction force and prevent the clamping member 2 from returning to its original position under the action of the first biasing member 6. Figure 3 The lower end of the force-applying portion 50 is provided with a pressing hole 51 and a locking portion 52. The pressing hole 51 is located above the locking portion 52 and extends in a direction perpendicular to the vertical direction. The lower end of the locking portion 52 has an outwardly extending and downwardly inclined inclined surface, and the upper end has a limiting plane 521.

[0078] refer to Figure 3 、 Figure 4 、 Figure 5 The locking portion 52 of the force-applying portion 50 is adapted to slide downward and pass over the locking member 7, so that the lower end of the locking member 7 abuts against the force-applying portion 50, thereby preventing the force-applying portion 50 from moving upward and ensuring that the pressing member 30 is in a compressed state. Figure 3When the latch is in the closed position, the locking member 7 is in the closed position, and the latch has been locked, so that the latch can be locked directly. When the latch is in the open position, the locking member 7 is in the closed position, and the locking member 7 is locked. When the latch is in the open position, the locking member 7 is in the closed position, and the locking member 52 is locked.

[0079] The two ends of the second biasing member 71 act on the partition wall 14 of the base 1 and the locking block 72, respectively. When the locking block 72 and the locking portion 52 are engaged with each other, energy is stored. When the locking portion 52 passes over the locking block 72, the locking block 72 and the locking portion 52 are disengaged from the inclined surfaces, and the second biasing member 71 releases energy, causing the locking block 72 to return to a position where it abuts against the locking portion 52. The first biasing member 6 and the second biasing member 71 may be springs, rubber, magnetic members, etc.

[0080] refer to Figure 3 、 Figure 5 、 Figure 6 The first pressing member 8 is adapted to correspond to the locking block 72 when the locking block 72 and the locking portion 52 are in a limited position against each other. The first pressing member 8 slides with the pressing hole 51 of the force-applying portion 50 to push the locking block 72, disengaging the locking block 72 from the limited position, thereby allowing the force-applying portion 50 to move upward. The first pressing member 8 is reset when the force-applying portion 50 moves downward the next time, by transmitting the force applied by the second biasing member 71 to the first pressing member 8, thereby facilitating the next pressing operation.

[0081] In other embodiments, the force-applying portion 50 can also be subjected to force through a pulling member, which is connected to the force-applying portion 50. The force-applying portion 50 is configured as a pushing inclined surface 501 that tilts outward from top to bottom, and the pressing member 30 has a pushed inclined surface that slides on the pushing inclined surface 501; wherein: the pulling member is configured to extend outside the base 1 and is suitable for being pulled by the user, and the force-applying portion 50 slides relative to the base 1 under the pulling of the pulling member; the pushing inclined surface 501 can be used to abut against the pushed inclined surface to maintain compression. Of course, compression can also be maintained by a clamping plane 502, which is located above the pushing inclined surface 501 and is a vertical plane. By adding more clamping planes 502, the pull-down stroke can be controlled, and the feel of the operation can be controlled. The clamping member 30 can have a plane opposite to the clamping plane 502 to abut against the clamping plane 502.

[0082] During use, the faucet 60 is placed on the tabletop 20, and the mounting mechanism is moved upward, so that the through hole 11 is sleeved outside the tube portion 601. The clamping drive member 4 abuts the lower surface of the tabletop 20, causing the clamping member 2 to slide toward the locked position and abut against the tube portion 601. The force-applying portion 50 is pulled downward, causing it to act on the pressing member 30. The pressing member 30 moves upward and abuts below the tabletop 20, causing the base 1 to move downward as a whole. The clamping member 2 also has a downward trend until friction and / or the gap between the teeth of the clamping member 2 and the tube portion 601 is sufficient for the clamping member 2 to move downward. At this point, the clamping member 2 cannot move downward and maintains the locked position, so that the clamping member 2 will not be reset by the first biasing member 6. At the same time, the force-applying portion 50 passes over the locking member 7 and is stopped by the locking member 7, preventing it from sliding upward easily. Therefore, the pressing member 30 can also maintain its position, and the clamping member 2 can also maintain its locked position. When disassembly is required, the first pressing member 8 is pressed to separate the locking member 7 from the force-applying portion 50 . At this time, the force-applying portion 50 can slide upward, thereby restoring the pressing member 30 and the clamping component 2 .

[0083] Compared with the prior art, this embodiment has the following beneficial effects:

[0084] In an exemplary embodiment, a mounting mechanism is provided, which is suitable for being mounted on a pipe portion 601 of a faucet 60 located below a countertop 20 , and includes a base 1 and a clamping mechanism.

[0085] The base 1 has a through hole 11 for the pipe portion 601 to partially pass through, so that the pipe portion 601 can enter the space to be installed;

[0086] The clamping mechanism includes a clamping member 2 , a pressing member 30 and a force applying portion 50 .

[0087] The clamping member 2 is used to clamp the pipe portion 601. It is operably movable and is arranged on the base 1 in a locked posture and an unlocked posture. In the unlocked posture, the clamping member 2 is supported away from the pipe portion 601 so that the through hole 11 can be operably inserted into the pipe portion 601 from bottom to top, so that the pipe portion 601 can be installed; in the locked posture, the clamping member 2 is supported to contact the pipe portion 601 to prevent the pipe portion 601 from moving upward relative to the base 1. Therefore, when the faucet 60 moves upward, the clamping member 2 will have a tendency to move upward.

[0088] The pressing member 30 is supported on the base 1 in a manner that it can be operatively moved and displaced in the up and down directions during the movement. The pressing member 30 is used to abut against the lower surface of the table 20.

[0089] During the process of inserting the installation mechanism into the pipe portion 601 from bottom to top, the clamping member 2 first clamps the pipe portion 601. Through this action, the installation mechanism is supported on the pipe portion 601 and will not fall off, thereby forming a locking posture. In this locking posture, the installation mechanism only realizes the insertion into the pipe portion 601 and the locked position of the pipe portion 601, and does not provide a locking force to completely fix the faucet. Therefore, the entire upward insertion process does not require the user to provide any strength.

[0090] The force-applying portion 50 is configured to receive a downward force when the clamping member 2 is in the locked position and apply force to the pressing member 30, causing the pressing member 30 to move upward and press against the lower surface of the countertop 20. During the pressing process, the force exerted by the pressing member 30 on the base 1 is applied to the clamping member 2 supported on the base 1, causing the clamping member 2 to press against the faucet tube 601, thereby locking the faucet to the countertop via the clamping member 2 and the pressing member 30. The force-applying portion 50 is configured to be movable in response to the downward force. Therefore, during installation, based on the locked position of the clamping member 2, the operator does not need to forcefully push upward in the invisible and narrow installation space under the countertop 20. Instead, the operator can simply use the natural downward movement of their arm to provide the force-applying portion 50 with the force to move, thereby providing the pressing member 30 with the locking force to lock the faucet to the countertop 20. This ensures both stable installation of the faucet on the countertop 20 and easy blind installation under the countertop 20.

[0091] In an exemplary embodiment, the number of the clamping members 2 is at least two, and at least two clamping members 2 hold the tube portion 601 tightly in a locking posture, thereby achieving a better locking effect.

[0092] In one exemplary embodiment, the surface of the clamping member 2 adapted to abut against the tube 601 includes one of protrusions, grooves, or teeth that mate with the tube 601. This allows the clamping member 2 to not only securely hold the tube 601 but also, to a certain extent, maintain the vertical position of the tube 601. Even if a gap exists between the corresponding mating structure and the tube 601, the downward movement of the clamping member 2 due to the pressure member 30 abutting against the table 20 compensates for this gap, ensuring greater stability with the upper and lower ends of the mounting mechanism abutting against the table 20 and the tube 601, respectively.

[0093] In an exemplary embodiment, a guide slope is provided on the base 1 , and the guide slope is configured to gradually tilt upward along the movement direction of the pressing member 30 when the force is applied by the force applying portion 50 , thereby achieving displacement of the pressing member 30 .

[0094] In an exemplary embodiment, a pressing member 3 is further included, which includes the pressing member 30 and an intermediate block 40. The intermediate block 40 cooperates with the pressing member 30 through an upwardly inclined inclined surface to cause the pressing member 30 to move upward when the intermediate block 40 slides, thereby realizing the displacement of the pressing member 30.

[0095] In an exemplary embodiment, the force applying portion 50 is configured as a pushing inclined surface 501 that is inclined outward from top to bottom, and the pressing member has a pushed inclined surface that is slidably matched with the pushing inclined surface to achieve force application. The force applied to the force applying portion 50 is achieved by:

[0096] The force-applying member 5 is provided with the force-applying portion 50, and the force-applying member 5 is sleeved on the outside of the base 1 and forms an installation space with the base 1. The clamping member 2 and the pressing member 30 are arranged in the installation space, thereby protecting the clamping member 2 and the pressing member 30; wherein the force-applying member 5 is constructed as an annular sleeve that is easy for the user to grasp.

[0097] Or a pulling member connected to the force applying portion 50, the pulling member is configured to extend out of the base 1 and is suitable for being pulled by a user, and the force applying portion 50 slides relative to the base 1 under the pulling of the pulling member, thereby achieving force application.

[0098] In an exemplary embodiment, the force applying portion 50 is supported on the base 1 so as to be movable, thereby allowing the force applying portion 50 to release the force on the pressing member 30 , thereby achieving disassembly of the mounting mechanism.

[0099] In an exemplary embodiment, a locking member 7 is further included, and the force-applying portion 50 is suitable for sliding downward and passing over the locking member 7. The lower end of the locking member 7 is suitable for limiting the force-applying portion 50, thereby preventing the force-applying portion 50 from moving upward, thereby maintaining the posture of the clamping member 30 and preventing it from loosening.

[0100] In an exemplary embodiment, the force-applying portion 50 is provided with a locking portion 52; the locking member 7 includes a second biasing member 71 and a locking block 72, the locking block 72 is slidably connected to the base 1, and the upper end of the locking block 72 is adapted to cooperate with the lower end of the locking portion 52 on an inclined surface, so that when the locking portion 52 slides downward, it is driven to slide by the locking portion 52, so that the locking portion 52 passes over the locking block 72; the lower end of the locking block 72 is adapted to abut against the upper end limit of the locking portion 52, thereby preventing the force-applying portion 50 from moving upward; the two ends of the second biasing member 71 act on the base 1 and the locking block 72 respectively, so that when the locking portion 52 passes over the locking block 72, the locking block 72 is reset to abut against the limit of the locking portion 52, thereby achieving automatic locking.

[0101] In an exemplary embodiment, the locking block 72 and the locking portion 52 are restrained by a plane, thereby preventing the restraining state from being disengaged due to the action of the inclined surface, and making it more stable. Therefore, when the locking block 72 is not disengaged from the locking portion 52, the force-applying portion 50 cannot move upward. The first pressing member 8 is adapted to correspond to the locking block 72 when the locking block 72 and the locking portion 52 are restrained. The first pressing member 8 and the force-applying portion 50 are slidably engaged to push the locking block 72, so that the locking block 72 and the locking portion 52 are disengaged, thereby achieving disassembly.

[0102] In an exemplary embodiment, the clamping mechanism further includes a clamping drive member 4, which is supported on the base 1 in a manner movable relative to the base 1 to be supported. The clamping drive member 4 includes a clamping force receiving portion 41 and a pushing portion 42. The clamping force receiving portion 41 is pushed downward by the lower surface of the table 20 during the process of the base 1 being inserted into the tube portion 601 from bottom to top. The pushing portion 42 cooperates with the inclined surface of the clamping member 2 to drive the pushing portion 42 to push the clamping member 2 from the unlocked position to the locked position. The movement of the clamping member 2 to the locked position is automatically triggered by the installation process, which is more convenient.

[0103] In an exemplary embodiment, one of the pushing portion 42 and the clamping member 2 has an inclined groove 21, and the other has an inclined block 421 suitable for inserting into the inclined groove 21, so that the upward movement of the pushing portion 42 can also realize the movement of the clamping member 2 to the unlocking posture. Conversely, the clamping member 2 will also affect the pushing portion 42, so that the two are linked to each other, and disassembly is also easier.

[0104] In an exemplary embodiment, it also includes a first biasing member 6, the two ends of which act on the base 1 and the clamping drive member 4 respectively to apply an upward force to the clamping drive member 4; or, the two ends of the first biasing member 6 act on the base 1 and the clamping member 2 respectively, and are suitable for applying a force to the clamping member 2 to move it toward the unlocking posture. Since the clamping member 30 forms a force toward the tube portion 601 applied to the clamping member 2, the force is greater than or equal to the force of the first biasing member 6. Therefore, after the installation is completed, it will not move to the unlocking posture due to the action of the first biasing member 6. When the clamping member 30 is not subjected to the force of the force-applying portion 50, the first biasing member 6 can move the clamping drive member 4 and the clamping member 2, so that the clamping member 2 moves to the unlocking posture to facilitate the disassembly of the tube portion 601.

[0105] Example 2

[0106] The main difference from the first embodiment is that this embodiment does not have the clamping drive member 4, and the method of driving the clamping member 2 is different.

[0107] refer to Figures 9-11In this embodiment, the force for the clamping member 2 to slide toward the locked position is achieved by a pressing force directly applied by the user to the clamping member 2, such as the clamping member 2 having a pressing portion extending from the force applying member 5 or the force applying portion 50;

[0108] Alternatively, during the downward movement of the force-applying portion 50, the force-applying portion 50 receives the downward force from the force-applying portion 50 by cooperating with the inclined surface of the clamping member 2, thereby causing the clamping member 2 to move toward the locked position. This cooperative relationship precedes the cooperation between the force-applying portion 50 and the pressing member 30. As for the reset of the clamping member 2 to the unlocked position, it is achieved by the third biasing member 9. The two ends of the third biasing member 9 act on the base 1 and the clamping member 2 respectively to apply a force to the clamping member 2 to cause it to move toward the unlocked position.

[0109] Furthermore, under the action of the third biasing member 9 , the clamping member 2 and the force applying portion 50 are pressed against each other to be in a locked position, thereby ensuring the stability of the locked position and preventing it from being reset due to the action of the third biasing member 9 .

[0110] In this embodiment, the force-applying portion 50 is adapted to slide until it abuts against the clamping member 2, preventing it from sliding upward. Specifically, the force-applying portion 50 is provided with a locking portion 52 (the structure of which may be the same as that of the first embodiment), the upper end of which is adapted to abut against the clamping member 2. This limited position can be released by allowing the force-applying portion 50 to move relative to the clamping member 2, thereby disengaging from the abutment with the clamping member 2. For example, when the force-applying portion 50 moves upward, it can engage with the inclined surface of the clamping member 2, allowing the locking portion 52 to pass over the clamping member 2, thereby disengaging from the abutment with the clamping member 2. In this embodiment, when the force-applying part 50 moves upward, it cooperates with the inclined surface of the clamping member 2 to make the clamping member 2 slide toward the locking posture (or the force-applying part 50 is deformed and thus passes over the clamping member 2), thereby releasing the limiting state. For example, the locking part 52 has inclined surfaces (or hemispheres 522) on both the upper and lower sides. The upper inclined surface is used to resist the clamping member 2 to disengage the limiting state of the force-applying part 50, and the lower inclined surface is used to resist the clamping member 2 to make the force-applying part 50 enter the limiting state. Preferably, the locking part 52 is elastic.

[0111] During use, the faucet 60 is placed on the table 20, and the mounting mechanism is moved upward so that the through hole 11 is sleeved outside the tube 601. The force-applying portion 50 is pulled downward so that it acts on the clamping member 2, causing the clamping member 2 to move to a locked position. The force-applying portion 50 also acts on the pressing member 30, causing the pressing member 30 to move upward and abut against the bottom of the table 20, causing the base 1 to move downward as a whole. The clamping member 2 also has a downward trend until the friction force and / or the gap between the teeth of the clamping member 2 and the tube 601 are sufficient for the clamping member 2 to move downward. At this point, the clamping member 2 cannot move downward and maintains the locked position. The friction force increases, preventing the clamping member 2 from being reset by the third biasing member 9. At the same time, the force-applying portion 50 passes over the clamping member 2 and is prevented from moving upward by the clamping member 2 to prevent it from sliding upward easily. Therefore, the clamping member 30 can also maintain its position. At the same time, under the action of the third biasing member 9, the clamping member 2 and the force-applying portion 50 are pressed against each other to be in a locked posture, further maintaining the stability of the clamping member 2.

[0112] When disassembly is required, the force applying portion 50 is moved upward so that the force applying portion 50 is separated from the pressing member 30 through the inclined surface engagement. At this time, the force applying portion 50 can slide upward to reset the pressing member 30 and the clamping component 2 (at the third biasing member 9).

[0113] The pressing member 30 can be reset, ie moved downward, by providing an elastic member, with both ends of the elastic member acting on the pressing member 30 and the base 1, thereby achieving its downward movement and reset, or by self-resetting.

[0114] Of course, in other embodiments, the limiting state of the force-applying portion 50 can also be achieved by the cooperation between the locking member 7 and the locking portion 52 , and unlocked by the first pressing member 8 .

[0115] Compared with the prior art, this embodiment also has the following beneficial effects:

[0116] In an exemplary preferred embodiment, the clamping member 2 is suitable for being pressed to move to a locking posture, that is, the clamping member 2 is partially suitable for being exposed from the base 1, such as exposed downward or laterally, so as to allow it to be pressed to achieve locking.

[0117] The clamping member 2 cooperates with the inclined surface of the force applying part 50 to move to the locking posture under the downward force of the force applying part 50. The force applying part 50 simultaneously realizes the movement of the clamping member 2 and the pressing member 30, which is more convenient to operate and has a simpler structure.

[0118] In one exemplary embodiment, a third biasing member 9 is further included. Its two ends act on the base 1 and the clamping member 2, respectively, to apply a force to the clamping member 2 toward the unlocked position. The clamping member 2 abuts against the force-applying portion 50 to maintain a locked position, thereby maintaining a stable position of the clamping member 2. The force-applying portion 50 is adapted to move relative to the clamping member 2 to disengage from the abutment therewith. Consequently, under the action of the third biasing member 9, the clamping member 2 automatically moves to the unlocked position, facilitating disassembly.

[0119] In an exemplary embodiment, the force-applying portion 50 is provided with a locking portion 52, the upper end of the locking portion 52 is suitable for abutting against the clamping member 2, and is suitable for cooperating with the inclined surface of the clamping member 2 when moving upward so that the locking portion 52 passes over the clamping member 2 to disengage from the abutment with the clamping member 2, so that the force-applying portion 50 can be disengaged from the abutment with the clamping member 2 by moving upward, so that the clamping member 2 automatically moves to the unlocked posture under the action of the third biasing member 9, and the operation is simpler and more convenient.

[0120] Example 3

[0121] The main difference from the first embodiment is that this embodiment does not have the clamping drive member 4, and the method of driving the clamping member 2 is different.

[0122] In this embodiment, reference Figure 12-15 ,

[0123] The force-applying member 5 comprises a fifth biasing member 70, a sliding member 80, and a force-applying portion 50. The ends of the fifth biasing member 70 act on the base 1 and the clamping member 2, respectively, and apply a force to the clamping member 2 to cause it to move toward the unlocked position. The sliding member 80 slides in conjunction with the base 1 up and down, and is adapted to slide upward under the pressure of the clamping member 2. After sliding upward, the sliding member 80 no longer blocks the opening of the first sliding hole 12, allowing the clamping member 2 to move to the locked position. The sliding member 80 has a trapezoidal cross-section, and the upper end of the sliding member 80 is provided with an inclined surface that tilts downward and inward, which is used to cause the clamping member 2 to retract inward when it is above the inclined surface and moves downward.

[0124] The clamping member 2 is also supported on the force-applying portion 50, which is movably supported on the base 1. The force-applying portion 50 is suitable for driving the clamping member 2 to move upward relative to the base 1 when the upper end of the base 1 is against the lower surface of the table 20, so that when the clamping member 2 moves to the locking height, it is moved to the locking posture under the action of the fifth biasing member 70 to be clamped on the tube portion 601; the clamping member 2 is suitable for being pushed upward by the force-applying portion 50 in the locking posture to cooperate with the inclined surface of the base 1 to slide to the unlocking posture, and the force-applying portion 50 has a second sliding hole 53 for sliding cooperation of the clamping member 2, and the second sliding hole 53 extends in a direction perpendicular to the up and down directions. The base 1 is provided with a third sliding hole 17 corresponding to the second sliding hole 53. The end of the clamping member 2 facing away from the tube portion 601 is positioned within the second sliding hole 53 and the third sliding hole 17. At least one of the clamping member 2 and the third sliding hole 17 is provided with a first inclined surface 171 extending outward and tilting upward, so that when subjected to an upward force, the clamping member 2 engages with the inclined surface of the base 1 to move toward the unlocked position. As the force-applying portion 50 continues to move, the clamping member is adapted to pass upward over the slider 80. The slider 80 then falls after the clamping member 2 passes over the slider 80. This prevents the clamping member 2 from returning to the locked position when the force-applying portion 50 drives the clamping member 2 downward relative to the base 1.

[0125] When the force applying portion 50 slides downward, it acts on the pressing member 30 (same as above), thereby achieving the movement of the pressing member 30 .

[0126] Installation process:

[0127] refer to Figure 12-15 Initially, the clamping member 2 is pressed against the base 1 by the fifth biasing member 70. The force-applying portion 50 is adapted to drive the clamping member 2 to move upward relative to the base 1 when the upper end of the base 1 is pressed against the lower surface of the table 20, and push the sliding member 80 to move upward, so that the sliding member 80 gradually opens the opening of the first sliding hole 12. When the clamping member 2 moves up to the locking height, it is moved to the locking posture by the action of the fifth biasing member 70 to be clamped on the tube part 601; since the clamping member 2 is restricted by the base 1, it will not fall; at this time, the force-applying part 50 is pulled down, and the force-applying part 50 pushes the pressing member 30 to move obliquely upward to achieve locking; when it is to be disassembled, the force-applying part 50 is pushed upward, wherein the pushing stroke is greater than the pulling stroke, and the force-applying part 50 slides upward, pushing the clamping member 2 through the hole wall of the second sliding hole 53 to apply an upward force to the clamping member 2. Under the action of the first inclined surface 171, the clamping member 2 tilts outward and moves upward, retracts inward, and is thus in the unlocking posture, thereby achieving the disassembly of the installation mechanism; at the same time, during the upward movement, the force-applying part 50 drives the clamping member 2 to cross the sliding member 80 supported on the base 1. The sliding member 80 falls after the clamping member 2 passes (by its own weight or by an elastic member), blocking the opening of the first sliding hole 12.

[0128] When the force-applying portion 50 moves the clamping member 2 downward relative to the base 1 to reset, the first sliding hole 12 remains blocked because the slider 80 does not move upward, preventing the clamping member 2 from returning to the locked position. The inclined surface of the slider 80 causes the clamping member 2 to retract downward over the slider 80 and return to its initial position. This structure allows the initial position to be restored by pulling down the force-applying portion 50, providing greater convenience.

[0129] The above description and embodiments are intended to explain the scope of protection of the present invention, but do not constitute a limitation thereto. Modifications, equivalent substitutions, or other improvements to the embodiments of the present invention or portions thereof that can be obtained by a person of ordinary skill in the art through logical analysis, reasoning, or limited experimentation based on the teachings of the present invention or the above embodiments, combined with common knowledge, ordinary technical knowledge in the field, and / or prior art, should all be included within the scope of protection of the present invention.
