Abstract
The utility model provides an improved device for liquid sale, which is composed of a cylinder, a piston, a piston drive mechanism, gear position bolts, a liquid inlet pipe, a liquid outlet pipe, a liquid inlet one-way valve, a liquid outlet one-way valve, a filter, etc., wherein the piston drive mechanism comprises a straight gear wheel, a rack motion pair and a handle mechanism. Because a piston type structure is used and a hulking barrel is not arranged, the utility model can be used by directly inserting the utility model into a liquid carrying container by the liquid inlet pipe and one-way valves. The utility model reduces the volume and the weight, is convenient for dismantling, portability, maintenance and retail and can be used for the retail of liquid goods, such as edible oil, fuel oil, detergent, etc.
Description
The utility model relates to a kind of piston type liquid conveying device in high capacity hold-up vessel retail input movable vessel.
Liquid vending machines such as edible oil, fuel oil and detergent are widely used in market.For example the long-term edible oil vending machine that uses of China's grain and oil department mainly is made up of from the quantitative mechanism of 250～1500g staving, cylinder body and a cover.Its staving is formed by tinned sheet iron and the riveted joint of section bar skeleton; Cylinder body is made up of cylinder and piston, the motion of piston is driven by gear and tooth bar kinematic pair, the rotation of gear is finished by a cover handle mechanism, and gear shaft is by being suspended in the outer a pair of little bearing supporting of cylinder body, and whole cylinder body is fixed on the upper cover skeleton of staving by securing member.Quantitatively mechanism comprises location guide pillar and 6 quantitative keys, and quantitative key is installed in one to have in the box body of scale.But the rectilinear motion of positioning guide column auxiliary rack.
The shortcoming of aforesaid liquid vending machine mainly is that structure is comparatively complicated, and machine volume is big, and weight is also big, and especially the staving that benzene is heavy had both increased cost, was not easy to again dismantle and carry.In addition, also must pour the oil in the oil drum into staving in advance during use.
The purpose of this utility model is to provide a kind of designs simplification, and volume is little, and is in light weight, the improved piston type liquid vending machine that cost is low.
The utility model adopts piston cylinder operator, comprises cylinder body, piston and piston drive mechanism, gear screw, retaining valve, pipeline and cylinder body capping.Piston is positioned at cylinder body, can do the up-downgoing straight reciprocating motion.Piston drive mechanism is made up of spur gear, tooth bar kinematic pair and handle mechanism, the tooth bar kinematic pair is fixed on the piston, and tooth bar kinematic pair upper end is an elbow, the rotation of handle drives the rotation of spur gear, and spur gear and tooth bar kinematic pair are converted into the rotation of spur gear the up-downgoing straight reciprocating motion of piston.The gear screw is located in the capping position near rack bore, and it defines the stroke of tooth bar with the elbow of tooth bar upper end, and pipeline is established feed tube and drain pipe, and the feed tube upper end is connected with cylinder base, and with the cylinder body perforation, and the feed liquor retaining valve is equipped with in the lower end; The lower end of drain pipe is connected by the cylinder base place with side of cylinder block, and connects with cylinder body, and top also is provided with the fluid retaining valve, and establishes bent portion with the exit.
Lower end at feed tube preferably is provided with a filtrator, in case impurity enters.
Bottom at cylinder body preferably is provided with a boss, so that this machine is fixed on the opening part of barrel cage, also can establish screw thread on boss, so that this machine is screwed on the opening of barrel cage.
The utility model is compared with existing liquid vending machine, owing to do not establish staving, utilize feed liquor pipeline and retaining valve that this machine is directly inserted in the carrying container and can use, remove the trouble of pouring into liquid in advance from, reduce volume and weight widely, be convenient to dismounting, carry and safeguard, be convenient to the retailer and use, and reduced cost, this machine can be used for the retail of liquid commodities such as edible oil, fuel oil, washing agent.
Fig. 1 is a main pseudosection of the present utility model.
Fig. 2 is a right pseudosection of the present utility model.
Fig. 3 is a vertical view of the present utility model.
Following examples will be further described structure of the present utility model, principle, adjusting and use in conjunction with the accompanying drawings.
As Fig. 1～shown in Figure 3, the utility model is made up of cylinder body (1), tooth bar kinematic pair (2), spur gear (3), handle mechanism (4), piston (5), feed tube (7), feed liquor retaining valve (8), filtrator (9), drain pipe (6), fluid retaining valve (10), capping (11) and gear screw (12).This machine adopts piston cylinder operator, forms the driving mechanism of piston by spur gear, tooth bar kinematic pair and handle mechanism, the rotation of the rotation drive spur gear of handle, and the wheel and rack kinematic pair is converted into rotation the up-downgoing straight reciprocating motion of piston.Form vacuum at cylinder body during upstroke, fluid retaining valve (10) is closed under the effect of atmospheric pressure, and feed liquor retaining valve (8) is opened, and liquid enters cylinder body by feed tube (7); During descent of piston, the feed liquor closed check valve, the fluid one-way valve opens, liquid enters bottle by drain pipe.
In order to improve the accuracy of systematic quantification, need the sealing of strengthening system, the piston lateral surface is provided with 3 grooves, and adopts 3 elastic alloy O-ring seals (5.1).
For ease of carrying, feed tube can be designed to dismountable two parts to be formed, and adopts to be spirally connected or socket.
The top of feed tube is connected with cylinder base, and connects with cylinder body.The bottom of drain pipe is connected by the cylinder base place with side of cylinder block, and connects with cylinder body; And bent portion (6.1) is established on top.
The upper end of tooth bar kinematic pair (2) is one 90 ° elbow (2.1), defines the stroke of tooth bar with gear screw (12), with this this machine is measured.The position of gear screw can be estimated by following formula:
h＝h
0－4G／πρd
2
H wherein
0Be the vertical range of the upper dead center of rack linear motion apart from the capping upper surface, h is the vertical range of gear screw top apart from the capping upper surface, and G is quantitative weight (500g or 1000g), and ρ is the density of liquid of being measured, and d is the internal diameter of cylinder body.
Obviously the step surface that the sealing of retaining valve can the tube road cooperates with the circular conical surface of retaining valve and realizes.Tooth bar can be assembled together by the circular hole on a cylinder and straight pin and the piston.The structure of bearing gear shaft can be overlapped on together by two auricles, and is connected in the capping by two screws, and the capping lower surface is welded with 3 auricles, and the threaded hole that passes these 3 auricles with 3 screws is fixed on capping on the cylinder body.
Be provided with boss in cylinder base, be convenient to this machine is fixed on the opening part of barrel cage.
