As illustrated in the structures in FIGS. 1-5 of the utility model patent “Retractable Tube Connector Structure” published in Jun. 1, 2014 with publication number M479372 and filing number 102222745, the retractable water tube can only be connected with an external water source and cannot control the outlet of water.
As stated in the structures mentioned in the abstract of the utility model patent “Improved Positioning Structure of “Retractable Squirt Tube” published in Jun. 1, 2007 with publication number M313198 and filing number 95222047: an inner tube being disposed inside an outer tube, a limiting plug being fixedly disposed at an inserting end of the inner tube, an upper limiting ring sleeve and a lower limiting ring sleeve being fixedly disposed at two ends of the outer tube respectively, the upper limiting ring sleeve being used for the inner tube to go through and for limiting the limiting plug at the end of the inner tube, the upper limiting ring sleeve and the lower limiting ring sleeve being used for preventing the inner tube from detaching from the outer tube, the upper and lower limiting ring sleeves having a sleeving space inside, the sleeving space having an inner circumferential wall protruded from a bottom edge and apart from an outer circumferential wall so that an inserting trough being formed between the inner circumferential wall and the outer circumferential wall for fitting the outer tube, the inner and outer circumferential walls being disposed inside and outside the tubes. Based on the above structures, the limiting ring sleeves disposed at the ends of the outer tube can prevent gap from forming both in dry and wet conditions for keeping secure combinations between the structural members.
As shown in FIGS. 1, 2, 3, 4 and 6, a lower limiting ring sleeve 50 disposed at a lower end of an outer tube 10 does not provide the structure and function that can control the outlet of water, it can only connect the retractable water tube with an external water source. It has to couple with an additional water control structure as shown in FIG. 7 in order to control the water outlet. Thus, the structure is more complicated and it is inconvenient in usage. Furthermore, the complicated structure may increase the manufacturing costs. Therefore, there remains a need for a new and improved telescopic water gun to overcome the problems stated above.
The present invention of a telescopic water gun aims to solve the above drawbacks of the conventional retractable water tube structure; namely, the connector disposed at the lower end of the outer tube cannot control the water outlet, and need to be coupled with another water control structure; making the structure more complicated, inconvenience in usage and the increase of costs.
A primary objective of the present invention is to provide a telescopic water gun with an inner tube and an outer tube which can be retractably operated for speedily positioning, and a water inlet connector disposed at one end of the outer tube which can be used for opening or closing water outlet.
A secondary objective of the present invention is to provide a telescopic water gun with a simple structure for achieving the function of opening and closing water outlet, and thus the manufacturing costs can be reduced.
A telescopic water gun in the present invention may include:
an inner tube, with one end coupled with a water outlet gun for forming a water outlet end, the other end sleeved inside an outer tube;
the outer tube having a deformable restraint ring disposed at the end sleeving with the inner tube, a blocking sleeve being sleeved below the deformable restraint ring, an upper end of the blocking sleeve being disposed with an outer thread section screwed with a pressing sleeve for tightly sleeving on the outer thread section and for tightly and fixedly screwing and pressing the deformable restraint ring around the inner tube, a water inlet connector and a water inlet controlling sleeve being sleeved at another end of the outer tube;
the water inlet connector being a sleeving structure and disposed with a water receiving end with a larger hole diameter and a smaller diameter sleeving end corresponding to the outer tube, a large diameter water stopping section and a small diameter water stopping section disposed therebetween, and a water controlling section between the large diameter water stopping section and the small diameter water stopping section, two water inlet holes and two water outlet holes disposed at a middle section arranged at higher and lower levels respectively being disposed on an outer wall of the water controlling section; and
the water inlet controlling sleeve sleeving around the water controlling section with its inner diameter, a large diameter opening being formed at a lower end of the water inlet controlling sleeve for sleeving around the large diameter water stopping section, a water controlling and guiding trough corresponding to the water inlet hole and the water outlet hole being concavely and longitudinally disposed in the inner diameter, the water inlet controlling sleeve being turned for aligning the water controlling and guiding trough, the water inlet hole and the water outlet hole offsetly and correspondingly and for opening or closing water outlet.
In one embodiment, the deformable restraint ring has an outer circular conical surface and is dissectionally disposed with at least one deformable indentation. An inner wall of the pressing sleeve is disposed with an inner circular conical surface corresponding to the outer circular conical surface. The deformable restraint ring can be tightly fixed around the inner tube by screwing the pressing sleeve around the outer thread section.
In another embodiment, two switching block portions adjacent to the large diameter water stopping section are protrudingly disposed on an outer wall of the water controlling section of the water inlet connector. A switching arced trough corresponding to the switching block portion is concavely disposed on an inner diameter of the water inlet controlling sleeve by a side below each of the two water controlling and guiding troughs. A length between two ends of the switching arced troughs of the water inlet controlling sleeve and the switching block portions form a distance turning combination for positioning and blocking. Thereby, the water controlling and guiding troughs, the water inlet holes and the water outlet holes can be aligned offsetly and correspondingly for opening or closing water outlet.
In still another embodiment, a pressing protruded edge is proturdingly disposed on a lower section of the inner tube. An expanded outer blocking edge is disposed on an inner wall at an end of the outer tube sleeving with the inner tube, and a rolling protruded edge is convexly disposed below the outer blocking edge on the inner wall of the outer tube for blocking and limiting the pressing protruded edge of the inner tube. Thereby, the inner tube can be retractably and limitedly operated.
In a further embodiment, the large diameter water stopping section and the small diameter water stopping section of the water inlet connector have a concavely disposed circular trough sleeved with a water stopping ring respectively.
In still a further embodiment, an outer circumference of each of the two water outlet holes of the water inlet connector has a concavely disposed circular trough sleeved with a circular water stopping piece.
The present invention will become more fully understood by reference to the following detailed description thereof when read in conjunction with the attached drawings.
The inner tube 10 with an end coupled with a water outlet gun 11 for forming a water outlet end, and another end sleeved inside the outer tube 20. A pressing protruded edge 12 is protrudingly disposed on a lower section of the inner tube 10.

The distance turning is achieved by the switching arced troughs 42 of the water inlet controlling sleeve 40 corresponding with the water controlling and guiding troughs 41. When the water controlling and guiding troughs 41, the water inlet holes 362 and the water outlet holes 363 are turned offsetly, the inner diameter of the water inlet controlling sleeve 40 is pressed against the water stopping pieces 37 around the water outlet holes 363. Thereby, outlet of water is closed.
The telescopic water gun of the present invention is featured with the inner tube and the outer tube which can be retractably operated for speedily positioning, and the water inlet connector disposed at the other end of the outer tube can be used for opening or closing water outlet. The opening and closing of water outlet can be achieved by the simplified structures. Thus, the structural assembling can be simplified effectively for reducing the costs and it is economically efficient.
Note that the specifications relating to the above embodiments should be construed as exemplary rather than as limitative of the present invention, with many variations and modifications being readily attainable by a person of average skill in the art without departing from the spirit or scope thereof as defined by the appended claims and their legal equivalents.
