Detailed Description of the Specific Embodiment

[0036] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0037] The present invention relates to a pulling and hovering mechanism, including a support member 100 and a lifting assembly 300.

[0038] Such as Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, the support member 100 can be configured as a box-like structure, or can be configured in various structural forms such as a frame-like, a frame-shaped, a plate-shaped structure, etc., but not limited thereto. A plurality of sets of guiding structures 200 are provided on the support member 100, and the guiding structures 200 are sequentially distributed along the height direction of the support member 100. Among them, the guiding structure 200 can be directly provided on the inner wall of the support member 100, or can be provided on some independent components such as a plate-shaped member, and then the member is installed on the support member 100 for use. In this embodiment, the support member 100 is box-shaped, and the guiding structures 200 are provided on a set of opposite inner walls of the support member 100. The guiding structure 200 includes a first rail 210, a second rail 220, and a stopping position 230. The first rail 210 and the second rail 220 on the same guiding structure 200 are located above the stopping position 230. According to the distribution position of the guiding structure 200, the one located above between two adjacent guiding structures 200 is the upper guiding structure 200, and the one located below is the lower guiding structure 200. In the illustrated direction, the first rail 210 and the second rail 220 are distributed left and right. The first rail 210 and the second rail 220 extend in the up and down direction. The upper end of the first rail 210 of the lower guiding structure 200 guides toward the lower end of the first rail 210 of the upper guiding structure 200. The lower end of the first rail 210 then guides toward the stopping position 230 in the same guiding structure 200. The stopping position 230 can guide toward the lower end of the second rail 220 above it. The upper end of the second rail 220 in the lower guiding structure 200 guides toward the lower end of the first rail 210 in the upper guiding structure 200. The lower end of the second rail 220 of the upper guiding structure 200 guides toward the upper end of the second rail 220 in the lower guiding structure 200. The lifting assembly 300 can be installed in the support member 100, and the lifting assembly 300 can be lifted relative to the support member 100. The lifting assembly 300 includes a sliding member 310, and the sliding member 310 is used for sliding connection into the guiding structure 200, and the sliding member 310 slides in the guiding structure 200 as the lifting assembly 300 is lifted and lowered. The sliding member 310 can be in a columnar, spherical, block-shaped structure, etc. Among them, the lifting assembly 300 can be used for installing the pipe fitting 400, or can also be applicable to the use of other components in cooperation with the lifting assembly 300. In this embodiment, the combination use of the lifting assembly 300 and the pipe fitting 400 is taken as an example for description. The pipe fitting 400 expands and contracts relative to the support member 100 as the lifting assembly 300 is lifted and lowered.

[0039] During the actual use process, initially, the lifting assembly 300 can be located at the bottom of the support member 100. As Figure 4 shown, the initial position of the sliding member 310 can be at the bottom of the support member 100, and most of the pipe fitting 400 is received in the support member 100. Then, the pipe fitting 400 is pulled out toward the outside of the support member 100, and the lifting assembly 300 rises relative to the support member 100. As Figure 6As shown in the figure, when ascending, the sliding connector 310 leaves the initial position, then slides in the direction of the lowermost first rail 210 and enters the first rail 210. As the lifting assembly 300 ascends, the sliding connector 310 slides along the first rail 210. The sliding connector 310 is guided to move from the first rail 210 of the current guiding structure 200 towards the first rail 210 of the upper guiding structure 200 and enters the upper first rail 210. If the lifting assembly 300 keeps ascending, the sliding connector 310 slides along each first rail 210 in sequence. As Figure 7 shown in the figure, after the pipe fitting 400 is pulled out to the maximum length or a certain required length for use, when the pipe fitting 400 is released, the lifting assembly 300 will slide downward relative to the support member 100 under its own gravity, and the sliding connector 310 will slide downward along the current first rail 210 accordingly. After the sliding connector 310 slides out of the lower end of the first rail 210, it will be guided to move towards the stop position 230 below the first rail 210 until the sliding connector 310 overlaps on the stop position 230. At this time, the lifting assembly 300 hovers at the current height of the support member 100 through the cooperation of the sliding connector 310 and the stop position 230, and the pipe fitting 400 also remains at the current pulled-out length. As Figure 7 shown in the figure, after the lifting assembly 300 hovers, if it is necessary to continue pulling out the pipe fitting 400, the sliding connector 310 moves upward away from the stop position 230, and then the sliding connector 310 will move towards the second rail 220 above the stop position 230 and enter the second rail 220. As the lifting assembly 300 continues to ascend, the sliding connector 310 will ascend along the second rail 220, and then after leaving the upper end of the second rail 220, it will move towards the lower end of the first rail 210 of the upper guiding structure 200 and re-enter the first rail 210. The sliding connector 310 that re-enters the first rail 210 can continue to move upward through each first rail 210 in sequence, or move downward to overlap on the corresponding stop position 230. If it is necessary to accommodate the pipe fitting 400 into the support member 100 at the current position, after the lifting assembly 300 hovers at a certain stop position 230, the pipe fitting 400 is pulled upward so that the lifting assembly 300 drives the sliding connector 310 to move upward away from the current stop position 230, and then enters the upper second rail 220. As Figure 9As shown, then release the pipe fitting 400. The lifting assembly 300 drives the sliding connector 310 to move downward along the second rail 220 under its own gravity, and the pipe fitting 400 retracts into the support member 100. The sliding connector 310 slides out downward from the lower end of the current second rail 220 and is guided to move in the direction of the upper end of the second rail 220 of the lower layer guiding structure 200, and the sliding connector 310 enters the second rail 220 of the lower layer. As the lifting assembly 300 descends, the sliding connector 310 slides downward along each second rail 220 in sequence and resets to the bottom of the support member 100. Based on the above working principle, the lifting assembly 300 can lift and hover in the support member 100, so that the pipe fitting 400 can extend and retract relative to the support member 100 and stop at a certain length position for use. The cooperation between the sliding connector 310 and the guiding structure 200 realizes the stepless hovering of the pipe fitting 400 and the lifting assembly 300, and the pulling force on the pipe fitting 400 is a constant force, with a comfortable pulling feel and convenient operation.

[0040] The present utility model also relates to a water outlet device applying the above-mentioned pulling and hovering mechanism. One end of the pipe fitting 400 can be connected to a water supply system, such as a water heater, a water pipe, etc., and the other end of the pipe fitting 400 can be connected to components such as a faucet, a spray gun, a shower head, etc. The use of the water outlet device is facilitated by the pulling and hovering mechanism.

[0041] In some embodiments of the present utility model, as Figure 1 and Figure 2 shown, the support member 100 is arranged as a box-shaped shell structure, and an accommodation cavity 110 is defined inside the support member 100. The guiding structure 200 is arranged on the cavity wall of the accommodation cavity 110. It can be on one of the cavity walls of the accommodation cavity 110, or the guiding structure 200 can be symmetrically arranged on a group of opposite side walls of the accommodation cavity 110. The lifting assembly 300 is located in the accommodation cavity 110. When the guiding structure 200 is arranged on one of the cavity walls, the sliding connector 310 is correspondingly arranged on one side of the lifting assembly 300. When the guiding structure 200 is arranged on two opposite cavity walls, the sliding connectors 310 are correspondingly arranged on both sides of the lifting assembly 300. The pipe fitting 400 is accommodated in the accommodation cavity 110. When the pipe fitting 400 is pulled out of the accommodation cavity 110, the lifting assembly 300 rises, and when the pipe fitting 400 contracts into the accommodation cavity 110, the lifting assembly 300 descends.

[0042] In some embodiments of the present utility model, as Figure 4 and Figure 5As shown, a guide groove 120 is provided on the side wall of the support member 100, and the guide groove 120 extends vertically along the height direction of the support member 100. The guiding structure 200 is arranged in the guide groove 120. The guiding structure 200 further includes a first convex portion 240, a second convex portion 250, a third convex portion 260, and a fourth convex portion 270. The first convex portion 240, the second convex portion 250, the third convex portion 260, and the fourth convex portion 270 are all formed as bumps on the inner wall of the guide groove 120. Among them, in the same guiding structure 200, the second convex portion 250, the third convex portion 260, and the fourth convex portion 270 are all located above the first convex portion 240. The third convex portion 260 and the fourth convex portion 270 are respectively located on the left and right sides of the second convex portion 250. A stop position 230 is formed by downward depression on the upper side surface of the first convex portion 240. The depressed shape of the stop position 230 can be V-shaped, U-shaped, etc., but is not limited thereto. As Figure 7 shown, when the sliding connection member 310 overlaps on the stop position 230, the sliding connection member 310 can stay at the lowest point of the depressed portion on the upper side of the first convex portion 240. A first track 210 is formed by the interval between the third convex portion 260 and the left side of the second convex portion 250. A second track 220 is formed by the interval between the fourth convex portion 270 and the right side of the second convex portion 250.

[0043] Specifically, as Figure 5 shown, a first transition groove 121 is formed by the interval between the left side of the first convex portion 240 and the left side wall of the guide groove 120. The left side wall of the first convex portion 240 can extend vertically, and the first transition groove 121 is a vertically extending groove body. The lower end of the first transition groove 121 faces the upper end of the first track 210 in the lower layer guiding structure 200. The upper end of the first transition groove 121 is horizontally offset from the lower end of the first cabinet located above it (i.e., in the same guiding structure 200). As Figure 6 shown, when the sliding connection member 310 moves from the first track 210 of the lower layer guiding structure 200 to the first track 210 of the upper layer guiding structure 200, it will pass through the second transition groove 122 to ensure the guiding of the first track 210 of the lower layer to the first track 210 of the upper layer. And when entering the first track 210 of the upper layer from the first transition groove 121, due to their horizontal offset, there will be a damping feel when pulling the pipe fitting 400. At this time, if the pipe fitting 400 is released, as Figure 7As shown, the sliding connector 310 will slide down from the first rail 210 of the upper layer and fall onto the stop position 230 of the same guiding structure 200, instead of falling back from the first rail 210 of the upper layer into the first transition groove 121. A second transition groove 122 is formed at an interval between the right side of the first protrusion 240 and the right side wall of the guiding groove 120. The right side wall of the first protrusion 240 can extend vertically, so the second transition groove 122 is also a vertically extending groove. The lower end of the second transition groove 122 is offset left and right from the upper end of the second rail 220 located below it, and the upper end of the second transition groove 122 faces the lower end of the second rail 220 located above it. As Figure 9 shown, when the sliding connector 310 moves from the second rail 220 of the upper guiding structure 200 to the second rail 220 in the lower guiding structure 200, it will pass through the second transition groove 122. As Figure 10 shown, when the sliding connector 310 moves upward from the second rail 220 of the lower guiding structure 200, due to the left-right offset between the second transition groove 122 and the second rail 220 of the upper layer, the sliding connector 310 will not move upward through the second transition groove 122, but will directly move upward in the direction of the first rail 210 of the upper layer.

[0044] Furthermore, the third protrusion 260 protrudes arcuately from the left side wall of the guiding groove 120 towards the second protrusion 250. The left side wall of the second protrusion 250 has a first straight surface 251 and a first inclined surface 252 distributed vertically. The first straight surface 251 is a vertical surface, and the first inclined surface 252 slopes from the upper left side to the lower right side. A upper part of the first rail 210 is formed between the first straight surface 251 and the side wall of the guiding groove 120, that is, the upper part of the first rail 210 extends vertically. As Figure 6 shown, the upper part of the first rail 210 vertically faces the first transition groove 121 located above it, ensuring that the sliding connector 310 moves upward stably from the first rail 210 in the lower guiding structure 200 into the first transition groove 121. A lower part of the first rail 210 is formed between the first inclined surface 252 and the side of the third protrusion 260, that is, the lower part of the first rail 210 slopes from the upper left side to the lower right side, and the lower part of the first rail 210 extends towards the stop position 230 located below it. When the sliding connector 310 moves upward from the first transition groove 121, it will first abut against the lower arc surface of the third protrusion, and then slide upward along the lower arc surface of the third protrusion into the lower part of the first rail 210. When the sliding connector 310 slides downward in the first rail 210, it will move towards the stop position 230 according to the orientation of the lower part of the first rail 210.

[0045] Specifically, the fourth convex portion 270 protrudes arcuately from the right side wall of the guide groove 120 toward the second convex portion 250. The right side wall of the second convex portion 250 has a second inclined surface 253 and a third inclined surface 254 distributed vertically. The second inclined surface 253 slopes from the upper left side to the lower right side, and the third inclined surface 254 slopes from the upper left side to the lower right side along the lower end of the second inclined surface 253. The upper end of the second inclined surface 253 is connected to the upper end of the first straight surface 251 to form a sharp angle. The lower side of the first convex portion 240 is a fourth inclined surface 241. The fourth inclined surface 241 slopes from the upper left side to the lower right side, and the fourth inclined surface 241 can be parallel to the second inclined surface 253. The third inclined surface 254 and the lower side wall of the fourth convex portion 270 are spaced apart to form a second track 220. The lower part of the second track 220 slopes downward and to the right toward the second transition groove 122 located below it. As Figure 9 shown, when the sliding connector 310 moves downward in the second track 220, it will approach the right side wall of the guide groove 120 under the guiding action of the second track 220, and then move downward along the right side wall into the second transition groove 122. The second inclined surface 253 and the upper side of the fourth convex portion 270 form a constricted area 123 that gradually narrows from top to bottom. The lower end of the constricted area 123 communicates with the second track 220. The upper second transition groove 122 is opposite to the upper side position of the corresponding fourth convex portion 270 below. The second inclined surface 253 and the fourth inclined surface 241 are parallel to each other and spaced apart to form a third transition groove 124. The third transition groove 124 slopes from the adjacent first transition groove 121 toward the upper end of the second track 220, that is, the third transition groove 124 slopes from the upper left side to the lower right side. When the sliding connector 310 moves downward from the second transition groove 122, it will enter the lower constricted area 123 and abut against the arc surface on the upper side of the fourth convex portion, and then move downward along the arc surface on the upper side of the fourth convex portion into the second track 220. As Figure 10 shown, when the sliding connector 310 moves upward from the second track 220, the sliding connector 310 will enter the third transition groove 124 that the sliding connector 310 moves upward into from the second track 220, and then abut against the fourth inclined surface 241 and enter the first track 210.

[0046] In some embodiments of the present invention, such as Figure 1 、 Figure 2 and Figure 3As shown, the lifting assembly 300 includes a movable pulley seat 320 and a counterweight 330. The movable pulley seat 320 can be set to a semi-circular shape, with a flat upper side and a semi-circular lower side. The counterweight 330 is installed on the movable pulley seat 320 to increase the overall weight of the lifting assembly 300. The sliding connector 310 is slidably installed on the movable pulley seat 320, and the pipe fitting 400 is wound around the movable pulley seat 320. The movable pulley seat 320 moves up and down relative to the support member 100, and the sliding connector 310 moves relative to the movable pulley seat 320 when moving along the guiding structure 200. The pipe fitting 400 changes direction through the movable pulley seat 320 and increases the length of the pipe body stored in the support member 100. Among them, the width dimension of the movable pulley seat 320 can be set to be slightly smaller than the width of the accommodating cavity 110. When the movable pulley seat 320 moves up and down, in cooperation with the pipe fitting 400, it can limit the rotation of the movable pulley seat 320 in the accommodating cavity 110, so that the movable pulley seat 320 moves up and down while maintaining the current orientation.

[0047] Furthermore, the lifting assembly 300 further includes a fixed pulley seat 340. The fixed pulley seat 340 is installed on the upper part of the support member 100 and is located above the movable pulley seat 320. The fixed pulley seat 340 can be rotatably installed on the top of the support member 100 through a rotating shaft. Two coaxially arranged first sliding grooves 321 are provided on the circumference of the movable pulley seat 320. The two first sliding grooves 321 are combined, and a number of first balls 322 are installed in each first sliding groove 321. The pipe fitting 400 slides around one of the first sliding grooves 321, the fixed pulley seat 340, and the other first sliding groove 321 in sequence. In this way, the telescopic length of the pipe fitting 400 relative to the support member 100 can be effectively increased, that is, the length that the pipe fitting 400 can be pulled out is longer. Both ends of the pipe fitting 400 are led out from the upper part of the support member 100. The pipe fitting 400 abuts on the first balls 322 in the first sliding groove 321, and the friction between the pipe fitting 400 and the movable pulley seat 320 is reduced through the first balls 322.

[0048] Among them, the sliding connector 310 is a second ball. The movable pulley seat 320 is provided with a second sliding groove 323. The second sliding groove 323 is horizontally arranged, and the second ball is slidably installed in the second sliding groove 323. As the movable pulley seat 320 moves up and down and the second ball moves along the guiding structure 200, the second ball slides relative to the movable pulley seat 320 along the second sliding groove 323.
