Description

Technical Field

[0001] The utility model relates to the technical field of lifting faucets, and in particular to a stable supporting structure for a lifting faucet. Background Art

[0002] The lifting faucet stable support structure is a support system designed specifically for liftable faucets. Through the lifting rod, mounting tube, damping collar and sealing gasket, it achieves the height adjustability and stability of the faucet body, providing people with a more convenient, comfortable and safe water experience.

[0003] Upon investigation, the Chinese utility model patent with publication number CN211449795U discloses a lifting faucet, including a main body and a water outlet assembly. The main body is penetrated along a first direction to form a first channel, and also includes: a sleeve, which is inserted into the first channel and fixedly connected to the main body; a lifting pipe, which is inserted into the sleeve and moves along the length direction of the sleeve, and its end is fixedly connected to the water outlet assembly; a positioning rubber ring, which is fixed on the lifting pipe and tightly fitted to the inner wall of the sleeve. The lifting faucet with the above structure can realize the change of water outlet height and the fixation of height position, and can also realize the free rotation of the faucet.

[0004] However, during the lifting and lowering process of the above-mentioned faucet, the user needs to apply a force greater than the damping to make it move, and the same amount of force needs to be applied whether it is raised or lowered. As a result, many users often choose not to reset the faucet after completing the lifting action due to the inconvenience of applying force, or simply give up using the lifting function, which greatly reduces the convenience of the lifting faucet. In addition, in order to ensure that the faucet can work stably after lifting, designers often set the damping to be relatively large. Although this enhances stability, it creates an additional usage burden for user groups with less strength, such as the elderly, women and children. They often need to make extra efforts when operating, which directly affects the user experience of this user group, and makes the faucet lose some operability and user-friendliness while providing height adjustment function.

[0005] Therefore, it is necessary to design a stable support structure for a lifting faucet to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a stable support structure for a lifting faucet.

[0007] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0009] Preferably, a slide groove connected to the guide groove is symmetrically provided in the lifting tube, a movable rod is slidably installed in the slide groove, an inclined surface is provided on the end of the movable rod close to the guide groove, an annular groove adapted to the slide groove is provided at the end of the lifting tube away from the base, a mounting groove connected to the annular groove is provided on the bent tube, an operating ring is rotatably sleeved in the mounting groove, a guide ring adapted to the annular groove is fixedly installed at the end of the operating ring away from the bent tube, and two arc-shaped bosses respectively adapted to the two movable rods are fixedly installed at the end of the guide ring away from the operating ring, and the height of the protruding end of the arc-shaped boss is the same as the height between the bottom of the movable rod and the bottom of the guide groove.

[0010] Preferably, the bottom of the movable rod and the top of the guide groove are arranged coplanarly.

[0011] Preferably, the rotating mechanism includes a sleeve rotatably mounted in the base and a sliding groove provided on the sleeve, the lifting tube is slidably connected to the sleeve, and a guide block adapted to the sliding groove is fixedly mounted on the lifting tube.

[0012] Preferably, limiting edges adapted to the guide blocks are fixedly mounted on both ends of the base.

[0013] Preferably, a limiting block is fixedly installed on the bottom of the sleeve, and a limiting groove adapted to the limiting block is provided on the limiting edge at the bottom of the base, and the limiting block can rotate along the limiting groove by 180°.

The buffer spring ensures that the damping block can automatically slide back along the inclined surface of the groove, resuming the damping support function for the lifting tube and preparing for the next adjustment.

[0020] 2. By providing an operating ring and a movable rod, the interaction between the curved boss and the movable rod allows the damping block to deflect and release the resistance to the lifting tube, allowing users with less strength to easily adjust the faucet height with a simple turn. The optimized slope of the curved boss further reduces the resistance encountered by users during rotation, improving ease of use.

[0021] 3. By setting up a buffer airbag, it can provide effective deceleration and buffering when the lifting tube moves to the limit edge, avoiding damage to the lifting tube caused by collision and extending its service life. The two buffer airbags are connected by a capillary tube, which can provide a stable buffering effect when impacted, and automatically balance the air pressure after the buffering is completed and return to the initial state, so that the buffer system can work stably and continuously, and can provide effective protection for each adjustment.

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0032] Reference Figure 1-8 , a stable support structure for a lifting faucet, including a base 1, a handle 2 arranged on the base 1 and a lifting tube 3 slidably installed in the base 1, a curved tube 4 is fixedly installed on one end of the lifting tube 3 away from the base 1, and a pull-out faucet 5 is provided on the other end of the curved tube 4, and a function button 51 is provided on the pull-out faucet 5. Two grooves 6 are symmetrically provided on the lifting tube 3, and a guide groove 61 is provided on the top wall of the groove 6. A damping block 62 is slidably installed in the groove 6, and a guide portion 63 is slidably installed in the guide groove 61. A yield groove 64 is provided on the top wall of the damping block 62, and a fixing rod 65 passing through the guide groove 61 is fixedly installed on the guide portion 63. The fixing rod 65 is slidably connected to the yield groove 64 and a buffer spring 66 is fixedly installed between the fixing rod 65 and the yield groove 64. A rotating mechanism is provided in the base 1; a plurality of evenly distributed damping rings 12 are fixedly installed on the outer wall of the damping block 62 opposite to the sleeve 8;

[0033] When the height of the faucet needs to be adjusted upward, an upward force can be applied to the elbow 4 or other parts of the faucet. At this time, the lifting tube 3 moves upward, and the damping block 62 can be lifted upward by abutting the lower surface wall of the groove 6 with the damping block 62. At this time, due to the effect of the bottom plane of the groove 6, the damping block 62 and the groove 6 do not move relative to each other. At this time, the damping block 62 abuts against the rotating mechanism and provides friction resistance through the damping ring 12, so that the elbow 4 can be stably maintained at any required position. At the same time, the setting of the damping ring 12 can reduce the contact area between the damping block 62 and the side wall, so that the resistance generated by the control friction can be significantly weakened, so that the faucet can be lifted with less effort. When the faucet needs to be lowered after use When resetting, the faucet body can be pressed downward. At this time, the lifting tube 3 starts to move first, and the damping block 62 will change its movement state later than the lifting tube 3 due to inertia. At this time, the damping block 62 is separated from the groove 6, and under the pressure of the side wall, it drives the fixing rod 65 and the guide part 63 to move a certain distance into the groove 6, so that the damping effect of the damping block 62 can be terminated, so that the faucet can be reset with less effort. After resetting, the damping block 62 slides and resets along the inclined surface of the groove 6 under the action of the buffer spring 6, and restores the damping support effect on the lifting tube 3, which can reduce the resistance effect of the faucet when resetting, making the adjustment of the resetting process simpler and more convenient than the operation when lifting, bringing a good user experience.

[0034] Reference Figures 3 to 7 The lifting tube 3 is symmetrically provided with a slide groove 7 connected to the guide groove 61, and a movable rod 71 is slidably installed in the slide groove 7. The end of the movable rod 71 close to the guide groove 61 is provided with an inclined surface. The end of the lifting tube 3 away from the base 1 is provided with an annular groove 72 adapted to the slide groove 7, and the bent tube 4 is provided with a mounting groove 73 connected to the annular groove 72. An operating ring 74 is rotatably sleeved in the mounting groove 73. The end of the operating ring 74 away from the bent tube 4 is fixedly provided with a guide ring 75 adapted to the annular groove 72. The end of the guide ring 75 away from the operating ring 74 is fixedly provided with two arc-shaped bosses 76 respectively adapted to the two movable rods 71. The height of the protruding end of the arc-shaped boss 76 is the same as the height between the bottom of the movable rod 71 and the bottom of the guide groove 61; the bottom of the movable rod 71 is coplanar with the top of the guide groove 61.

[0035] When users with less strength raise the faucet height, they can rotate the operating ring 74, which drives the guide ring 75 and the arc-shaped boss 76 to rotate. When the arc-shaped boss 76 rotates, it squeezes the movable rod 71 to move downward along the slide groove 7, and squeezes the guide part 63 through the inclined surface of the guide groove 61, squeezing the guide part 63 toward the center of the lifting tube 3. The guide part 63 drives the damping block 62 to slide inward through the fixed rod 65. At the same time, under the action of the inclined surface of the groove 6, the damping block 62 moves obliquely upward and squeezes the buffer spring 66. At the same time, due to the damping block 62 The offset means that the lifting tube 3 is no longer affected by resistance when moving, and the user can easily lift the faucet to the desired position. After the lifting is completed, the operating ring 74 is released, and the buffer spring 66 can push the damping block 62 to reset, while driving the movable rod 71 and the operating ring 74 to reset. By setting the bottom surface of the movable rod 71 to be coplanar with the top surface of the guide groove 61, the movable rod 71 only needs to move a short distance to separate the damping block 62 from the system, thereby making the slope of the arc-shaped boss 76 gentler, which can save effort when using the operating ring 74 and is convenient for users to use.

[0036] Reference Figure 2 、 Figure 5 and Figure 8 The rotating mechanism includes a sleeve 8 rotatably mounted in the base 1 and a sliding groove provided on the sleeve 8. The lifting tube 3 is slidably connected to the sleeve 8, and a guide block 81 adapted to the sliding groove is fixedly mounted on the lifting tube 3; both ends of the base 1 are fixedly mounted with a limiting edge 82 adapted to the guide block 81; a limiting block 83 is fixedly mounted on the bottom of the sleeve 8, and a limiting groove 84 adapted to the limiting block 83 is provided on the limiting edge 82 at the bottom of the base 1. The limiting block 83 can rotate along the limiting groove 84 by 180 degrees.

[0037] The rotating sleeve 8 can adjust the faucet to different angles for use. By rotating the faucet body such as the elbow 4, the lifting tube 3 and the guide block 81 can be driven to rotate. The guide block 81 can push the sliding groove and the sleeve 8 to rotate in the base 1, thereby adjusting the use angle. When the faucet is lifted, the guide block 81 can slide up and down in the sliding groove without affecting the rotation of the sleeve 8, and the limiting edge 82 can prevent the lifting tube 3 from being pulled out of the base 1. When the limiting block 83 rotates in the limiting groove 84, its rotatable angle will be subject to the size of the limiting groove 84, so that the faucet rotation angle can be limited to a maximum of 180°, while fully ensuring the convenience of use, avoiding losses caused by collision with walls or other objects due to excessive rotation angles.

[0038] Reference Figure 6 and Figure 7A fixed edge 9 is fixedly installed on the end of the slide groove 7 away from the operating ring 74, and a clearance opening adapted to the fixed edge 9 is opened on the movable rod 71. A return spring 91 is fixedly installed between the movable rod 71 and the fixed edge 9; a return torsion spring 10 is fixedly installed between the outer wall of the guide ring 75 and the inner wall of the annular groove 72, and an anti-slip groove 101 is opened on the outer wall of the operating ring 74;

[0039] The reset spring 91 and the reset torsion spring 10 respectively drive the operating ring 74 and the movable rod 71 to reset, which can avoid the buffer spring 66 taking on the reset task and inevitably increasing the pressure on the damping block 62, thereby causing the problem of excessive resistance during lifting and lowering. When using the faucet, the hands are likely to be in a wet state. At this time, it is easy to slip when rotating the operating ring 74, resulting in the inability to rotate the operating ring 74. After providing the anti-slip groove 101, the friction between the hand and the operating ring 74 can be increased to avoid slipping and causing abnormal use, thereby ensuring a stable user experience.

[0040] Reference Figure 8 , a buffer airbag 11 is fixedly mounted on the opposite ends of the two limiting edges 82, and a capillary tube 111 is provided between the two buffer airbags 11;

[0041] When the lifting tube 3 drives the guide block 81 to move to the limit edge 82, the lifting tube 3 can be decelerated and buffered by squeezing the buffer airbag 11, so as to prevent the lifting tube 3 from colliding with the limit point due to failure to decelerate in time, thereby affecting the service life of the lifting tube 3. When the buffer airbag 11 on one side is impacted, the gas can be pressed into the buffer airbag 11 on the other side through the capillary 111, and the pressure required for exhaust is increased by the capillary 111 to ensure effective buffering of the lifting tube 3. After the buffering is completed, the air pressure on both sides can be balanced through the capillary 111, so that the buffer airbag 11 returns to its initial state, ensuring that the buffer airbag 11 can provide stable and effective protection each time it is adjusted.

[0042] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
