Abstract
The utility model relates to a quick liquid filling pipe, which is especially suitable for a household air conditioner. The quick liquid filling pipe is composed of a pipe body, a steel ball, a spring, a baffle board, a check ring and a columnar rubber ring, wherein, the pipe body is formed once by injection moulding, then the columnar rubber ring, the steel bal, the spring and the baffle board are in turn arranged in the pipe body, and at last, the columnar rubber ring, the steel bal, the spring and the baffle board are pushed in a clamp groove on an inner wall of the pipe body by the check ring, with installation completed. In the utility model, the closing and opening of the steel ball and the columnar rubber ring are controlled by that the spring generates telescopic change after the spring is pressed and is filled with liquid, and accordingly, the utility model reaches that rapid and convenient liquid filling, the quick liquid filling pipe can be sealed of own accord, and simultaneously, because a copper made piece is substituted by plastics, production cost is reduced.
Description
The utility model relates to the refrigeration accessory, is specially adapted to domestic air conditioner.
The present domestic air conditioner that uses, its topping up pipe mostly adopts copper fitting, needs the flat topping up pipe of pincers behind the topping up, and with the method for gas welding front cover.
The purpose of this utility model provides behind the topping up that a kind of plastics make promptly the quick topping up pipe of sealing voluntarily.
Art designs scheme of the present utility model: it is made up of body, steel ball, spring, baffle plate, back-up ring and cylinder type rubber ring, body is disposable injection molded, it is characterized in that being provided with in the body garden column type rubber ring and spring controlled steel ball, constitute switch gear, spring rear end is provided with baffle plate, baffle plate is controlled by back-up ring.
Described body 1, by the disposable injection molded hollow shape of plastics, intermediate section inner chamber front end is provided with a plug 11, and the rear end is provided with a draw-in groove 12.
Described baffle plate is by tinsel punching out triangularity shape.
The utility model adopts above-mentioned measure, compares with original topping up pipe, have topping up fast, voluntarily the sealing, can save raw metal, reduced cost of production.
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated
The cut-away view of Fig. 1, quick topping up pipe of the present utility model
Illustrate:
1, body 11, plug 12, draw-in groove 2, steel ball
3, spring 4, baffle plate 5, back-up ring 6, cylinder type rubber ring
With reference to Fig. 1 as can be seen, quick topping up pipe of the present utility model, formed by body 1, steel ball 2, spring 3, baffle plate 4, back-up ring 5 and cylinder type rubber ring 6, body 1 is by the injection moulding disposal molding, pack into successively subsequently cylinder type rubber ring 6, steel ball 2, spring 3, baffle plate 4 are urged to forward in the draw-in groove 12 with back-up ring 5 at last and get final product.Like this, insert the mouth of pipe of body 1 upper end when the topping up rifle, the pressure promotion steel ball 2 that produces by the topping up pressurization leaves and cylinder type rubber ring junction point, get through pipeline, at this moment, spring 3 is in compressive state, when stopping to dash, annotates by the topping up rifle, then spring 3 restores to the original state, and it is identical with the cylinder type rubber ring to promote steel ball 2, thereby reaches sealing voluntarily.
Described body 1, by the plastics once injection moulding, intermediate section inner chamber front end is provided with plug 11, the rear end is provided with draw-in groove 12, and plug 11 can stop 6 slippages of cylinder type rubber ring, can be by dress back-up ring 5 in the draw-in groove 12.
Described baffle plate 4 forms triangle by the tinsel punching out, makes baffle plate 4 and body 1 inwall leave the slit, fills liquid gas and passes through smoothly.
