When the connection mechanism of the first embodiment of the present invention is used, the lowest sleeve is pulled upward according to the height of the container (in the first embodiment of the present invention, the lowest sleeve is taken as the third sleeve 213), the third sleeve 213 will move upward along the second sliding slot 2125, so as to shorten the length of the sleeve assembly for the first time; when a shorter cannula assembly 2 is desired, the third cannula 213 can be pulled upward, and the friction between the third cannula 213 and the second cannula 212 will drive the second cannula 212 to move upward along the first sliding slot, thereby further shortening the length of the cannula assembly 2.
In a second embodiment of the present invention, a second,
as shown in fig. 4 and 5, a faucet connecting mechanism 10 comprises a connecting part 1, wherein the connecting part 1 is connected with a faucet water nozzle 100; a sleeve pipe assembly 2 is connected below the connecting part 1 in an adaptive manner; the sleeve assembly 2 comprises a plurality of sleeves 21 which are sequentially and tightly sleeved from top to bottom; when an upward force is applied to the lowermost sleeve 21, the plurality of sleeves 21 may be sequentially nested from bottom to top; when a downward force is applied to the lowermost sleeve 21 of the sleeved sleeve assemblies 2, the sleeves 21 of the sleeve assemblies 2 can be individually un-sleeved. Obviously, due to the tight fit between the sleeves 21, the user can adjust the length of the sleeve assembly 2 according to the need, i.e. adjust the position of each sleeve 21 according to the need.
In the second embodiment of the present invention, as shown in fig. 4 and 5, the second sleeve 212 is tightly sleeved in the first sleeve 211; the lower section of the second sleeve 212 is a retractable and expandable structure 2120; the outer wall of the upper section of the second sleeve 212 is provided with a third annular groove 214, and a third sealing ring 2141 is arranged in the third annular groove 214. Thus, when a user applies a downward pulling force to the second sleeve 212, the retractable and expandable structure 2120 is retracted and can be pulled out of the first sleeve 211.
In the second embodiment of the present invention, the connection portion 1 and the sleeve assembly 2 are detachable, and obviously, the connection portion 1 and the top end of the sleeve assembly 2 may also be integrally formed. In the second embodiment of the present invention, a plurality of vertical through grooves 216 are uniformly distributed on the lower section of the second sleeve 212, the plurality of vertical barrel grooves 216 cut the lower section of the second sleeve 212 into a plurality of arc-shaped pieces 217, and the plurality of arc-shaped pieces 217 and the plurality of vertical through grooves 216 form a retractable and expandable structure 2120. Due to the existence of the plurality of vertical through grooves 216, when the second sleeve 21 tightly matched with the first sleeve 211 is pulled downwards, the plurality of arc-shaped sheets 217 can be retracted inwards and are easy to pull out; conversely, when the second sleeve 21 is pulled upward, the plurality of curved pieces 217 contract inward to easily sleeve the lower section of the second sleeve 212 into the first sleeve 211.
In order to enhance the adjustment of the multi-length of the sleeve assembly, in the second embodiment of the present invention, the third sleeve 213 is tightly sleeved inside the second sleeve 212, and the lower section of the third sleeve 213 is also a retractable and expandable structure 2130 which is the same as the lower section of the second sleeve 212; a fourth annular groove 2131 is formed in the outer wall of the upper section of the third sleeve 213, and a fourth seal ring 2132 is arranged in the fourth annular groove 2131. From this, can adapt to the container of different model sizes more for when thimble assembly can adjust multiple height, still can effectively prevent 2 inside leaks of thimble assembly.
Preferably, in order to avoid that the sleeve located below is dropped from the sleeve located above, the outlet of the top end of each sleeve in the sleeve assembly may be tapered inwards, i.e. such that the inner diameter of the top end of each sleeve is smaller than the outer diameter of the sleeve located inside it. That is, in the second embodiment of the present invention, the openings at the top ends of the first sleeve 211 and the second sleeve 212 may be both inwardly shrunk, so that the inner diameter of the top end is smaller than the outer diameter of the sleeved sleeve. Obviously, to further enhance the ease of handling of the sleeve assembly, the lower section of the first sleeve 211 may also be provided with the same retractable and expandable structure 2110 as the lower section of the second sleeve 212; this may facilitate when the second sleeve is moved upwards, while the upper section of the second sleeve 212 may be gripped by the collapsible and expandable structure 2110 of the first sleeve when the second sleeve is moved downwards.
In order to facilitate the operation of the user, in the sleeve assembly 2, a fixing ring 24 is disposed on an outer side wall of the uppermost sleeve (in the second embodiment of the present invention, the first sleeve 211 is the uppermost sleeve); the bottom end of the outer sidewall of the lowest sleeve (in the second embodiment of the present invention, the third sleeve 213 is the lowest sleeve) is connected with a handle 25, and the upper end of the handle 25 is rested in the fixing ring 24. Thereby being convenient for users to lift the sleeve and avoiding scalding.
By using the technical scheme of the second embodiment of the invention, when the water outlet height of the faucet needs to be adjusted, an operator can lift the handle 25 by hand and lift the lowest sleeve upwards, the invention takes the third sleeve 213 at the bottom as an example, the third sleeve 213 moves upwards into the second sleeve, and if the height is adjusted continuously, the handle 25 can be lifted upwards continuously, so that the second sleeve 212 is driven by the third sleeve 213 to move upwards into the first sleeve 211 continuously, thereby facilitating the water receiving use of containers with various heights.
In the embodiment of the present invention, each sleeve in the sleeve assembly 2 may be set to be a sleeve whose outer diameter is gradually reduced from the middle to both ends, so that the falling off of the sleeve can be effectively avoided.
In the technical scheme of the invention, the water receiving height of the water faucet can be properly adjusted by the water faucet connecting mechanism 10, and when water is taken, the water outlet nozzle can be inserted into inlets of water containers with various heights, so that hot water is prevented from spilling out of the containers, the ground around the water fountain is ensured to be dry and clean, and people are prevented from being splashed and injured.
The present invention is not limited to the above preferred embodiments, and any modifications, equivalent substitutions, improvements, etc. within the spirit and principle of the present invention should be included in the protection scope of the present invention.
