Description

A manual pressure-controlled volume liquid glue jet

technical field

The utility model relates to an office stationery product, in particular to a hand pressure controlled volume liquid glue jet.

Background technique

At present, the liquid glue used in the office mainly adopts the glue storage of the glue bottle and the glue cover installed on the glue bottle to supply the glue. Take out the stopper, install the glue cover, and put the glue upside down. Although it is relatively simple to apply glue in this way, there are still some shortcomings: firstly, the size of the glue feeding port of the glue bottle is fixed, and the glue bottle needs to be inverted and squeezed when feeding glue, so it is difficult to control the size of the glue feeding. Too much will cause waste, too little will not achieve the effect, and sometimes even apply it several times, which is inconvenient to use; secondly, at the end of the use of the glue bottle, there is less glue in the bottle, and the glue is difficult to flow out, and sometimes even needs to be applied. The glue will flow out only when the glue bottle is squeezed until it deforms, but in most cases people will discard the last bit of glue left, which not only causes waste, but also is not conducive to environmental protection; thirdly, some glue bottles are easy to be tripped, causing Glue spilled on the desk, staining documents and other items. Therefore be necessary to develop a kind of manual pressure control volume liquid glue sprayer to make up for the above-mentioned deficiency.

Utility model content

The purpose of the utility model is to develop a manual pressure-controlled volume liquid glue jet to overcome the deficiencies in the prior art.

The technical scheme of the utility model: a manual pressure-controlled volume liquid glue sprayer includes a spray pipe, the spray pipe is composed of a large spray pipe and a small spray pipe, the middle part of the spray pipe is connected with the spray support through a rotating shaft, The position exchange of the large jet tube and the small jet tube can be realized according to the needs. The junction of the jet tube and the jet bracket is designed with a diversion chamber, and the interface between the large jet pipe, the small jet tube and the diversion chamber is designed with round holes. , the liquid glue enters the jet pipe through the round hole in the wall of the distribution chamber, and an arc-shaped blocking valve is designed in the distribution chamber to make the liquid glue flow into the front jet pipe, and the fluid delivery pipe I passes the liquid glue through the side of the jet bracket Transported to the distribution chamber, the fluid delivery pipe I is nested in the spring pressure shaft, and the spring pressure shaft is nested in the rubber ring. The spring pressure shaft on the side of the rubber ring close to the pressure handle is provided with a fixed convex ring, and the other side is provided with a flow hole. , one end of the spring pressure shaft is fixed with the pressure handle through the movable shaft, and the other end is fixed with the spring. The suction chamber is set in the handle and connected to the lower end of the spring. Glass beads are arranged in the suction chamber, and a suction nozzle is arranged at the lower part of the suction chamber. The nozzle is connected with the fluid delivery pipe II, and the rubber storage bottle is screwed into the handle for sealing and fixing.

In the aforesaid a kind of manual pressure-controlled volume liquid glue sprayer, the cross-section of the spray nozzle of the large spray pipe is multi-hole shape, so as to facilitate the uniform and large-scale extrusion of the liquid glue, and the spray flow of the small spray pipe The cross-sectional diameter of the nozzle is not more than 1mm, which is beneficial to a small amount of glue feeding, so when the glue feeding amount is large, it is suitable to use a large jet tube, and when the glue feeding amount is small, it is suitable to choose a small jet tube;

In the aforementioned manual pressure-controlled liquid glue jet, the arc-shaped blocking valve is designed on the side close to the handle, and the two ends are fixed to the rotating shaft to prevent the liquid glue from spraying to the side of the handle, thereby ensuring that the liquid Glue flow to the front jet tube;

In the aforementioned manual pressure-controlled volume liquid glue jet, the rubber ring has two functions, one is to seal the longitudinal space between the spring pressure shaft and the suction chamber, and the other is to realize the flow hole between the rubber ring and the spring pressure shaft. selective blocking. When the spring is compressed by the pressing handle and the spring pressing shaft, the rubber ring is separated from the flow hole, and the liquid glue can flow into the jet pipe through the flow hole. When the spring rebounds, the rubber ring immediately blocks the flow hole, making the suction chamber form a negative pressure ;

In the aforesaid manual pressure-controlled liquid glue sprayer, the flow holes are the center of the circle, evenly distributed on the cross-section of the space of the spring pressing shaft, and communicated with the fluid delivery pipe I;

In the aforementioned manual pressure-controlled volume liquid glue jet, the glass beads can be selectively sealed with the suction nozzle. When the spring presses the shaft to compress the spring, the glass beads block the suction nozzle. When the spring rebounds, Under the action of negative pressure, the glass beads are separated from the suction nozzle, and the liquid glue in the glue storage bottle is sucked in.

Due to the adoption of the above-mentioned technical scheme, the utility model has the advantages that: the utility model adopts a hand-press type controlled amount of glue, which can effectively avoid the waste caused by excessive extrusion, and the effect of insufficient extrusion is not obvious; the utility model can be used according to needs. Choose a large jet tube or a small jet tube, which is easy to replace, flexible to use, and has a wider range of applications; the utility model does not need to squeeze the rubber bottle during use, which is convenient and practical; in addition, the utility model also adopts humanized design, according to According to the actual situation, the handle and the rubber storage bottle are reasonably designed. The utility model has a simple structure and is easy to control. It can be widely used in office work and improve work efficiency. It is worth popularizing and using.
