Top-penetrating type plastic hose assembly

Technical Field

The utility model belongs to the technical field of the plastic packaging bottle, a formula plastic hose subassembly is worn on top is related to.

Background

At present, most cosmetic hoses are composed of a hose body and a hose cover screwed on the hose body, cosmetic liquid is filled in the hose body, the bottom of the hose body is sealed through pressing, a liquid outlet port is formed in the upper end of the hose body, and emulsion is extruded out through extruding the hose body. Most hoses on the market are in an open state before being used, and are sealed by a plug or a thimble and liquid blocking column structure in a pipe cover, so that the disadvantage that the cover and the plug are easily opened by mistake to extrude the emulsion in the hose during transportation or sale is solved.

SUMMERY OF THE UTILITY MODEL

The utility model aims at having the above-mentioned problem to current technique, provided a formula plastic hose subassembly is worn on top, the play liquid end of hose body is in the encapsulated situation before first use, through extracting the packing ring, wears out the liquid end with the thimble top, has guaranteed better leakproofness before first use.

The purpose of the utility model can be realized by the following technical proposal: a top-through plastic hose assembly comprises a hose body, an upper cover and a gasket, and is characterized in that the cross sections of the hose body and the upper cover are elliptical, the gasket is provided with a moving part which can be inserted into the upper cover in a clamping manner, the gasket is provided with an auxiliary step, the lower end of the upper cover abuts against the auxiliary step, the bottom in the upper cover is vertically provided with a connecting sleeve, the inner side of the connecting sleeve is provided with a thimble, the inner wall of the connecting sleeve is provided with an internal thread, the upper end of the hose body is provided with a horizontal platform, the horizontal platform is provided with a vertically arranged liquid outlet end, the outer wall of the liquid outlet end is provided with an external thread matched with the internal thread, the distance between the lower end of the thimble and the upper end face of the liquid outlet end is 0.5-1 mm, the gasket is provided with a round hole for the liquid outlet end to pass through, the round hole and the connecting sleeve, the lower end face of the gasket is provided with a raised clamping block, and the clamping block can slide into the limiting groove.

When the flexible pipe is delivered from a factory, the upper end of the liquid outlet end is closed, the gasket is firstly pulled out from the upper cover during initial use, then the upper cover is buckled on the flexible pipe body to rotate, the thimble is gradually close to the liquid outlet in the rotating process until the thimble pushes the upper end of the liquid outlet end through, and then the gasket is inserted back into the upper cover. The mode has the advantages that the inner cavity of the hose body is in a closed state before the hose body is pushed through, so that the latex can be well stored, the leakage is avoided, and the sealing performance is good.

Furthermore, the moving part comprises arc-shaped positioning plates at two ends of the gasket and clamping strips positioned on the outer sides of the arc-shaped positioning plates, and the lower end of the upper cover is sleeved outside the arc-shaped positioning plates.

Furthermore, a plurality of vertically arranged support rods are arranged in the upper cover, and the support rods are abutted against the gasket.

Furthermore, the two support rods are connected with the connecting sleeve and are respectively positioned on two sides of the connecting sleeve.

Further, the check block is provided with a slope which is obliquely arranged. When the outer cover rotates, the gasket rotates synchronously, the clamping block falls into the limiting groove after passing through the check block, and the inclined surface facilitates the sliding of the clamping block.

Compared with the prior art, the top-wearing type plastic hose assembly has the following advantages:

1. during the use, the gasket is pulled out from the upper cover, then the upper cover is screwed on the hose body, and the upper cover can be screwed deeper due to the loss of the support of the gasket, so that the thimble can pierce the upper end face of the liquid outlet end and get through the liquid outlet end, the emulsion in the hose body can be extruded, and the accidental extrusion of the emulsion can be effectively avoided.

2. Simple structure, accessories are few, and low in manufacturing cost pierces through the thimble, does not need extra accessory, can also be used for the later stage to utilize after the thimble pierces moreover, screws up the upper cover when not using the emulsion and can be used for the shutoff to go out the liquid end.
