DETAILED DESCRIPTION OF THE INVENTION

(9) The present invention will be further described with the drawings and the embodiments.

(10) Referring to FIGS. 1-8, a hanging structure of an outlet terminal comprises an outlet terminal 1 and a hanging element 2. In this embodiment, the outlet terminal 1 is a hand-held shower head 1 and the hanging element 2 is disposed on a top spraying shower head. It should be noted that the scope of the present invention is not limited to this, since a person skilled in this field can change the hand-held shower head to other outlet terminals, and the hanging element 2 can be directly disposed onto the wall or other positions. These are simple substitutions of the technical proposal of the present invention so that they are not further described herein.

(11) The hanging structure for an outlet terminal also includes a hose 10 through which the outlet terminal 1 connects to the water source.

(12) When the outlet terminal 1 moves in a direction away from the hanging element 2, the hanging element 2 is in an elastic state, and an abutting force between the outlet terminal 1 and the hanging element 2 causes the hanging element 2 to open so that the outlet terminal 1 separates from the hanging element 2. When the outlet terminal 1 swings within the hanging element 2, the hanging element 2 is in a fixation state, and the outlet terminal 1 is maintained in a hanging state. Therefore, when the outlet terminal 1 is separates from the hanging element normally, the hanging element 2 doesn't limit the outlet terminal 1. However, if the outlet terminal 1 experiences an abnormal force, the hanging element 2 limits the movement of the outlet terminal 1, and the outlet terminal 1 is maintained in a hanging state despite the action of the abnormal force which otherwise might cause the outlet terminal 1 to fall down unexpectedly, such as a force that the outlet terminal 1 receives when the user pulls on the hose 10. To achieve above technical effect, the present invention is provided with the structure as follows:

(13) The hanging element 2 comprises a locking component 21 and a limiting component 22. When the outlet terminal 1 moves along a direction away from the hanging element 2, the locking component 21 separates from the limiting component 22 so that the limiting component 22 has no influence on the locking component 21, and an abutting force between the outlet terminal 1 and the locking component 21 causes the locking component 21 to open, and a clamping force of the locking component 21 onto the outlet terminal 1 is released. When the outlet terminal 1 swings within the hanging element 2, the limiting component 22 abuts against the locking component 21 and limits an abutting force between the outlet terminal 1 and the locking component 21 so that the locking component 21 does not open. This ensures that the locking component 21 always clamps the outlet terminal 1 to form a stable hanging structure.

(14) Furthermore, the locking component 21 comprises two locking arms 211 symmetrically arranged and having a lever structure. Each locking arm 211 has two ends, a first free end 2111 and a second free end 2112. A clamping chamber 24 which accommodates the outlet terminal 1 is defined between the first free ends 2111. A clamping force of the first free ends 2111 onto the outlet terminal 1 achieves the hanging of the outlet terminal 1. When the first free ends 2111 of the two locking arms 211 rotate in a direction that is opposite from one another to separate the first free ends 2111 from one another about a fulcrum 60, the second free ends 2112 of the two locking arms 211 rotate in a direction that is opposite from one another to close each other about the fulcrum 60. That is to say, when the first free ends 2111 of the locking arms 211 open, the second free ends 2112 close toward each other. An axis 50 is pass through the fulcrums 60 of the locking component 21.

(15) With this feature, when the outlet terminal 1 swings in the hanging element 2, the limiting component 22 moves to a position between the second free ends 2112 of the two locking arms 211, making the second free ends 2112 unable to rotate in the direction opposite to one another about the fulcrum 60. That is to say, if the second free ends 2112 cannot close toward each other, the first free ends 2111 cannot open. The outlet terminal 1 between the first free ends 2111 is clamped so that it does not fall down.

(16) To achieve movement of the limiting component 22 to a position between the second free ends 2112 of the locking component 21 due to an abnormal force and to other positions, the limiting component 22 separates from the locking component 21. In this embodiment, the locking component 21 further comprises a back plate 212, the limiting component 22 further comprises a limiting driving element 223 disposed at the back plate 212. In this embodiment, the back plate 212 is a side plate 212 and is a portion of a main body of a top side shower head that is disposed at the same side as that of an outlet cover plate 20 of the top side shower head.

(17) The locking arms 211 are disposed on a surface of the back plate 212. When the outlet terminal 1 swings in the hanging element 2, the outlet terminal 1 contacts the limiting driving element 223, thus triggering the limiting driving element 223 to drive the limiting component 22 to move to a position between the second free ends 2112 of the two locking arms 211.

(18) In more detailed, the limiting driving element 223 may comprise a squeezing surface 2231 exposed out of the back plate 212 and a pushing surface 2232 abutting against the limiting component 22. The squeezing surface 2231 and the pushing surface 2232 rotate about a rotating shaft 23 in a linked manner as illustrated in the enlarged view of FIG. 7. When the outlet terminal 1 swings in the hanging element 2, the outlet terminal 1 pushes into the squeezing surface 2231, making the squeezing surface 2231 and the pushing surface 2232 rotate in the linked manner, an abutting force between the pushing surface 2232 and the limiting component 22 pushes the limiting component 22 to move to a position between the second free ends 2112 of the two locking arms 211.

(19) The limiting component 22 may further comprise a sliding blocking 221 and a reset spring 222. The main body of the sliding blocking 221 is disposed within an axis of symmetry 25 of the two locking arms 211 and abuts against the pushing surface 2232. An abutting force between the pushing surface 2232 and the limiting component 22 pushes the sliding blocking 221 to slide to the position between the second free ends 2112 of the two locking arms 211 along the axis of symmetry 25, and the sliding blocking 221, when moving, squeezes the reset spring 222 to accumulate an elastic reset force. When the abnormal force on the outlet terminal 1 disappears, the reset spring 222 drives the sliding blocking 221 to move to an initial position to accomplish a reset.

(20) The locking component 21 may further comprise a torsion spring 213 having one end that is rotatably connected to the fulcrum 60. Sides of the two locking arms 211 that are opposite to one other are respectively disposed with an arc surface so that a clamping chamber 24 is formed between the two locking arms 211. A side of the clamping chamber 24 that is disposed away from the back plate 212 is an open end having a width that is smaller than width of the clamping chamber 24. When the outlet terminal 1 enters the clamping chamber 24, it squeezes the locking arms 211 at the two sides of the open end, making the first free ends 2111 of the locking arm 211 open outwardly. The outlet terminal 1 then enters the clamping chamber 24 normally. After the outlet terminal 1 enters the clamping chamber 24, the locking arms reset under the action of the torsion spring 213 and the locking arms clamps the outlet terminal.

(21) Although the present invention has been described with reference to the preferred embodiments thereof for carrying out the invention, it is apparent to those skilled in the art that a variety of modifications and changes may be made without departing from the scope of the invention which is intended to be defined by the appended claims.
