The present disclosure relates to a gardening fluid connection device which is employed to connect with a water spray gun, a sprinkler or a water hose.
A conventional gardening fluid connection device, such as disclosed in TW Patent Nos. 260238, 532442, 11319072 and U.S. Pat. No. 7,021,669, is employed to connect with a water supply device (e.g., a water spray gun, a sprinkler, or a water hose). The conventional gardening fluid connection device contains a fitting sleeve reciprocatingly rotated leftward or rightward so as to open or close the conventional gardening fluid connection device. When the fitting sleeve is stopped after being rotated, the user knows the conventional gardening fluid connection device is located on an opening position or a closing position. Alternatively, the user knows the conventional gardening fluid connection device is located on the opening position or the closing position after pressing the fitting sleeve. Furthermore, a conventional gardening fluid connection device such as disclosed in U.S. Pat. No. 7,021,669 contains an L-shaped depression defined in the fitting sleeve so that the stop rib of the fitting sleeve slides in a stopping face of the depression when being rotated to the closing position or the opening position, hence the conventional gardening fluid connection device is not positioned.
A primary aspect of the present invention is to provide a gardening fluid coupling device which is opened or closed easily by way of the stop rib and each locking element of the body, each spaced engagement tooth of the fitting sleeve, and the resilient element.
Another aspect of the present invention is to provide a gardening fluid coupling device in which each locking element rotates from a first side of each spaced engagement tooth toward the second side of each spaced engagement tooth, wherein each spaced engagement tooth is pushed by the resilient element to contact with the stop rib and each locking element of the body and to rotate toward the second side of each spaced engagement tooth, and each locking element rotates to the second side of each spaced engagement tooth, such that it is easy to distinguish whether the gardening fluid coupling device is opened or closed.
In an aspect, a gardening fluid connection device comprises a body on which multiple retainers are retained, a resilient element, and a fitting sleeve which are fitted on a first end of the body. The fitting sleeve includes multiple spaced engagement teeth and the resilient element abuts against the body and the fitting sleeve. Also, the fitting sleeve rotates along the body reciprocatingly and pushes the resilient element so as to open or close the gardening fluid coupling device, hence the multiple retainers of the body are removed or retained when the fitting sleeve presses the resilient element or is pushed by the resilient element so that the multiple retainers of the body connect with or remove from a water spray gun or a sprinkler. The body includes a stop rib arranged thereon so that the multiple spaced engagement teeth of the fitting sleeve are pushed by the resilient element to abut against the stop rib of the body. The body also includes at least one locking element formed inside the stop rib, wherein each locking element is located on a first side of each spaced engagement tooth, and wherein a width of each spaced engagement tooth is equal to a rotation distance of the fitting sleeve, such that the fitting sleeve is rotated reciprocatingly so as to open or close the gardening fluid coupling device by way of the stop rib and each locking element of the body, each spaced engagement tooth of the fitting sleeve, and the resilient element. Further, each locking element is stopped when moving to a second side of each spaced engagement tooth.
In another aspect, a gardening fluid connection device comprises a body on which multiple retainers are retained, a resilient element, and a fitting sleeve which are fitted on a first end of the body. The fitting sleeve includes multiple spaced engagement teeth and the resilient element abuts against the body and the fitting sleeve. Also, the fitting sleeve rotates along the body reciprocatingly and pushes the resilient element so as to open or close the gardening fluid coupling device, hence the multiple retainers of the body are removed or retained when the fitting sleeve presses the resilient element or is pushed by the resilient element so that the multiple retainers of the body connect with or remove from a water spray gun or a sprinkler. The body further includes at least one retaining element, and the fitting sleeve further includes at least one shoulder respectively located above and contacting with the retaining element so as to maintain the fitting sleeve on a closing position and not press downward when the fitting sleeve rotates to an opening position. The shoulder removes from the retaining element of the body so that the fitting sleeve presses the resilient element to release the multiple retainers, and the multiple retainers connect with or remove from the water spray gun or the sprinkler.
In yet another aspect, a gardening fluid connection device comprises a body on which multiple retainers are retained, a resilient element, and a fitting sleeve which are fitted on a first end of the body. The fitting sleeve includes multiple spaced engagement teeth and the resilient element abuts against the body and the fitting sleeve. Also, the fitting sleeve rotates along the body reciprocatingly and pushes the resilient element so as to open or close the gardening fluid coupling device, hence the multiple retainers of the body are removed or retained when the fitting sleeve presses the resilient element or is pushed by the resilient element so that the multiple retainers of the body connect with or remove from a water spray gun or a sprinkler. The body includes a stop rib arranged thereon so that the multiple spaced engagement teeth of the fitting sleeve are pushed by the resilient element to abut against the stop rib of the body. The body also includes at least one locking element formed inside the stop rib, wherein each locking element is located on a first side of each spaced engagement tooth, and wherein a width of each spaced engagement tooth is equal to a rotation distance of the fitting sleeve, such that the fitting sleeve is rotated reciprocatingly, and each locking element rotates from a first side of each spaced engagement tooth toward the second side of each spaced engagement tooth. The body further includes at least one retaining element, and the fitting sleeve further includes at least one shoulder respectively located above and contacting with the one or more than one retaining element so as to maintain the fitting sleeve on a closing position and not press downward when the fitting sleeve rotates to an opening position. The shoulder removes from the one or more than one retaining element of the body so that the fitting sleeve presses the resilient element to release the multiple retainers, and the multiple retainers connect with or remove from the water spray gun or the sprinkler.
Other objects and features will be in part apparent and in part pointed out hereinafter.
Corresponding reference characters indicate corresponding parts throughout the drawings.
With reference to
Referring further to
The fitting sleeve 40 further includes one or more than one elongated shoulder 44 respectively corresponding to and located above the one or more than one retaining element 17 so that the one or more than one elongated shoulder 44 moves across the one or more than one retaining element 17 when the fitting sleeve 40 is rotated. Each elongated shoulder 44 has a stopping face 45 defined on one side thereon so as to form a defining space 46, such that each limitation element 15 is located in the defining space 46 and is limited by each elongated shoulder 44 and the stopping face 45 when the fitting sleeve 40 rotates reciprocatingly. A width of each of the multiple spaced engagement teeth 43 is equal to a rotation distance of the fitting sleeve 40 in an embodiment.
