Description

Hand-twist connection device for the water outlet of the faucet

technical field

The utility model relates to a faucet, in particular to a hand-twist connection device for the water outlet of the water faucet, which can be directly tightened by hand and connected watertight to the water outlet without any auxiliary tool.

Background technique

As shown in Fig. 1, one of the water outlets of the existing faucet 90, currently, in order to connect an external water filter or securely connect a water pipe, the water outlet 91 of the water faucet 90 is often used either to clamp the outer end or to brace the inner wall. way, add a connection group 92, if the connection group 92 is an embodiment of the inner end bracing type, it can include: a connecting support 93, the connecting support 93 is in the shape of a hollow block, and the connecting support 93 The upper end is provided with an expansion part 931 whose diameter is larger than the diameter of the outer wall surface of the water outlet 91 of the faucet 90, so that the connecting support 93 can rely on the outer edge of the water outlet 91 of the water faucet 90. The center of the expansion part 931 longitudinally passes through a wall that also allows water to flow. The screw hole 933 passed through, and the external thread 934 is arranged on the outer edge of the bottom of the connecting member 93; a locking member 94, which is a round block that penetrates vertically, and the top of the locking member 94 expands outwards to a pressing surface 941, A locking recess 942 is cut upward on the bottom wall of the locking member 94, and a screw thread 943 is arranged on the outer edge of the locking member 94; In this way, a screwdriver 96 is first inserted into the water outlet 91 of the faucet 90, approximately in a vertical state, and then passes through the bottom of the supporting member 93, and is locked in the locking recess 942, so that The screwdriver 96 passes through the locking concave portion 942, and the locking piece 94 is screwed toward the direction of the connecting support piece 93. In this way, the watertight ring body 95 is pushed toward the faucet 90 due to the pressure of the pressed surface 941 and the expansion portion 931 up and down. The inner wall surface is tight and watertight.

With the above-mentioned existing structure, the connection group 92 is firmly supported by the watertight ring body 95 on the inner wall of the faucet 90 to produce a watertight effect, and the external thread 934 of the support member 93 is externally connected to the filter/water purification device or water pipe. However, as shown in FIG. 2 , the existing products have the following defects in actual application: (A) need to use corresponding auxiliary tools when assembling. Generally, the opening diameter of the water outlet (such as the faucet 90) is limited. Existing products need to use a screwdriver 96 to pass through the watertight ring body 95 and the locking member 94, except that a watertight ring body 95 is plugged in the water outlet part. The screwdriver head of the screwdriver 96 is fixed in the locking recess 942 in a small gap state below the locking member 94, so that the existing connecting group 92 can be locked. In such a locking method, except that the rod diameter d of the screwdriver 96 is smaller than the inner diameter t of the inner wall surface of the water outlet end 91 of the faucet 90, it is especially necessary that the screwdriver head of the screwdriver 96 can be inserted into the locking recess 942 in a small gap state. , such various conditions, I believe that those in the industry know that a general screwdriver 96 that can produce the power to lock the existing connection group 92 may not necessarily meet the requirements of the above-mentioned size conditions; in addition, if there is no screwdriver 96 at hand In the case of a special case, it is impossible to lock or remove it at all, which is very inconvenient. (B) It cannot be widely used in the water outlets of various faucets. One of the popular water outlets of the faucet 90, in order to avoid the plastic (such as PVC) water pipe from extending too long, the faucet is usually installed on the post and about a foot high from the ground. When the water is free from splashing out of the bucket, it is also conducive to cleaning sundries or rags, avoiding the situation of splashing; however, if the existing faucet 90 is located on the wall surface of the upper end of the washing machine, or other various factors, it will cause water to flow out. When the distance between the end 91 and any nearest object is D, the length of the screwdriver 96 that makes the watertight ring body 95 really watertight is B, and the length B is greater than the distance D. In this way, the screwdriver 96 cannot be stretched into the water tap 90. The water outlet end 91 is impossible to make the watertight ring body 95 watertight at all; certainly, perhaps the existing faucet can be applied to a glass table or a bathtub, but an object cannot be widely used in the same field, which is not ideal. Furthermore, even if the industry is allowed to go home to assemble such a device with a simple combination structure, although the problem of corresponding tools may not need to be considered, a watertight ring body 95 will produce elastic fatigue after being used for a period of time, and it must be pressed again. This is a problem that cannot be ignored. Therefore, existing products that cannot be fixed in bulk sizes cannot be widely used. Therefore, it is necessary to research and develop a hand-twist connection device for the water outlet with a simple structure and easy to use.
