Description

Technical Field

[0001] This application relates to the field of corrugated hose technology, and in particular to a pull-out hose for kitchen use. Background Technology

[0002] A pull-out hose is a corrugated hose used to connect the water outlet and the spray nozzle of a kitchen pull-out faucet. Pull-out hoses are widely used in restaurants, hotels, canteens, and home kitchens, bringing great convenience to people cleaning cookware and kitchen utensils.

[0003] The principle of a pull-out faucet is to add a counterweight under the pull-out hose so that the hose can automatically retract. However, in the current pull-out faucet, the water outlet component and the corrugated pipe are pulled to move and rinse during use. However, the pipe cannot be fixed during rinsing and can only be used by hand, which is inconvenient. At the same time, the counterweight on the existing pull-out hose may loosen after long-term use, affecting the retraction effect of the pull-out hose. Therefore, it is necessary to design a kitchen pull-out hose that can be fixed in length and is easy to adjust. Utility Model Content

[0004] This application provides a pull-out flexible tube for kitchens that can be fixed in length and is easy to adjust.

[0005] The technical solution provided in this application for a pull-out flexible kitchen hose is as follows:

[0006] A kitchen pull-out hose includes a corrugated pipe that passes through a support pipe and is connected to a water outlet assembly. A locking sleeve and a releasing sleeve are fitted on the outer side of the corrugated pipe. The locking sleeve is connected to the support pipe, and one end of the locking sleeve extends into the support pipe and is provided with a fixing part. The fixing part can engage with the outer side of the corrugated pipe. The releasing sleeve is located between the corrugated pipe and the locking sleeve, and can be inserted into the locking sleeve and can open the fixing part.

[0007] Preferably, the locking sleeve is a hollow cylindrical structure, one end of the locking sleeve is provided with a groove and is connected to the end of the support tube through the groove, and the fixing part includes a plurality of sheet-like structures or plate-like structures inclinedly arranged inside the end of the locking sleeve.

[0008] Preferably, the locking sleeve is threaded to the support pipe, and the outer side of the locking sleeve is provided with a plurality of anti-slip protrusions.

[0009] Preferably, the release sleeve is a hollow cylindrical structure, and an annular groove is provided on the outer side of the release sleeve. The locking sleeve is provided with an annular protrusion corresponding to the diameter of the annular groove, and the height of the annular protrusion is less than the height of the annular groove.

[0010] Preferably, a push-pull ring is provided at the end of the release sleeve away from the bellows, and a gap is provided between the push-pull ring and the annular groove.

[0011] Preferably, the inner diameter of the release sleeve is larger than the outer diameter of the bellows.

[0012] Preferably, the bellows is provided with counterweights, which are arranged in pairs and movably connected. The sides of the pairs of counterweights that are close to each other are provided with threaded protrusions that match the corrugations on the bellows.

[0013] Preferably, the outer side of the counterweight is provided with several annular grooves, and a fixing ring is provided in the annular groove. The fixing ring has a discontinuous structure and is made of elastic material.

[0014] Preferably, the corrugated pipe includes an inner pipe and an outer pipe. The inner pipe is a flexible hose made of PVC material, and the end of the inner pipe is provided with a retaining ring and a plastic joint. Both the retaining ring and the plastic joint are cylindrical, and the retaining ring is sleeved on the outside of the plastic joint. The end of the plastic joint is provided with several protrusions that match the inner side of the inner pipe. The two sides of the retaining ring are respectively connected to the outer side of the inner pipe and the inner side of the outer pipe.

[0015] Preferably, the outer tube is a stainless steel spiral corrugated tube, and the outer side of the retaining ring is provided with a threaded protrusion corresponding to the corrugation of the outer tube.

[0016] In summary, this application includes at least one of the following beneficial technical effects:

[0017] 1. This application provides a locking sleeve and a release sleeve on a bellows. The locking sleeve is connected to a support tube, and its end can be inserted into the support tube. The end of the locking sleeve inserted into the support tube is provided with a fixing part, which can be engaged with the outside of the bellows, thereby fixing the length of the bellows and facilitating its use. At the same time, a release sleeve is provided between the locking sleeve and the bellows. The release sleeve can be inserted into the locking sleeve to open the fixing part and unlock the bellows, facilitating its retraction and making it convenient to use.

[0018] 2. By setting a groove at the end of the locking sleeve and connecting it to the support tube through the groove, the position of the locking part inside the locking sleeve is fixed, ensuring the locking effect; by threading the locking sleeve to the support tube, loosening can be avoided, ensuring the connection effect.

[0019] 3. By providing an annular groove on the outer side of the release sleeve and an annular protrusion on the locking sleeve corresponding to the diameter of the annular groove, the release sleeve can be fixed by the locking sleeve. At the same time, since the height of the annular protrusion is less than the height of the annular groove, the release sleeve can move along the direction of the locking sleeve, making it easy to insert into the locking sleeve. By providing a push-pull ring on the release sleeve, the release sleeve can be moved. At the same time, a gap is provided between the push-pull ring and the annular groove to ensure that the push-pull ring can be pulled up, making it easy for the fixing part to reset and convenient to use. By setting the inner diameter of the release sleeve to be larger than the outer diameter of the bellows, the bellows can be smoothly pulled out, making it convenient to use.

[0020] 4. By setting a counterweight on the corrugated pipe, and setting a matching spiral protrusion on one side of the counterweight that is close to the corrugated pipe, the position of the counterweight is fixed and loosened. At the same time, the position of the counterweight can be adjusted by rotating the counterweight, thereby adjusting the extension length of the corrugated pipe for convenient use. A fixing ring is set on the counterweight to facilitate connection and fixation. Attached Figure Description
