Abstract
The utility model relates to a manual inflating tool, which is provided with a synchronous lubricating and filtering device. The bottom of a barrel wall (1) is provided with a device (2) which is composed of moisture absorption materials in which lubrication oil is fully immersed. When a piston (3) moves to the bottom, the piston (3) is led to contact the bottom of the device and is lubricated. An air outlet hole (4) is positioned above the device, and an air delivery pipe part is provided with a filtering device (5). Consequently, inflating objects are protected, and the inflating objects can not be polluted by lubrication oil.
Description
The utility model relates to a kind of inflatable tool, manual inflation's instrument of particularly various low pressure tyre inflations.
This inflatable tool is widely used when especially bicycle inner tube is inflated because its flexible, cheap characteristics are being various tires.Its utilizes manually push-and-pull piston in cylindrical shell, produces air pressure, air is pressed into be inflated in the object, and in use, because piston rubs for a long time with barrel, the critical piece leather cup that causes constituting piston easily is quick-wearing very, produces and leaks gas, and causes the air pressure deficiency.
For solving this contradiction, the practice is to soak leather cup in advance in lubricant oil usually, perhaps injects lubricant oil at set intervals in cylindrical shell.But during a method, lubricant oil can in use progressively vapor away before use, and is especially long-time during with the barrel friction when piston, can produce heat, the quickening volatilization process.When using back one method, can make troubles to the user inevitably, and owing to the quantity that injects lubricant oil in cylindrical shell is wayward, very fewly can not bring into play due effect, in the time of too much,, can cause grease accumulation and spray with air-flow because the air outlet hole of this instrument is in an interior bottommost, enter and be inflated in the object, infringement being inflated object.
The purpose of this utility model is, a kind of improved manual inflation's instrument is provided, and it can realize lubricated synchronously to piston, can protect again simultaneously to be filled object and be not subjected to the corrosion of lubricant oil.
The purpose of this utility model is achieved in that establishes a lubricating fitting that is made of hygroscopic materials that soaks full lubricant oil in cylinder inboard wall bottom, when piston runs to the bottom and is in contact with it, lubricated, thus the friction that alleviates piston and barrel; Air outlet hole is located at a little more than the lubricating fitting place, to avoid lubricant oil along hole ejection, establishes the filter that the soft object of porous constitutes in the air outlet hole outside, filtering a small amount of oil content that may spray, thereby plays the effect that protection is inflated object.
The utility model has been realized lubricating synchronously piston, can alleviate the friction of piston and cylinder inboard wall, prolong the working life of piston, also improved simultaneously the seal degree of piston and barrel, the trouble of having avoided the manual application of lubricant to bring, it only need increase two devices that are made of material cheap and easy to get and the position that changes air outlet hole, can be by original instrument simple refit is realized.In addition, filter also helps protection and is inflated object.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Accompanying drawing is according to the manual inflation's sectional drawing that the utility model proposes.
Describe the details and the working condition thereof of the concrete instrument that foundation the utility model proposes in detail below in conjunction with accompanying drawing:
This instrument comprises by cylindrical shell (1) and base (2) in conjunction with the cylinder body that forms, under pull bar (3) drive in cylinder body reciprocating piston (4) and gas delivery part.When exerting oneself to pressing down pull bar (3) piston (4) along arrow (5) direction, when moving downward, air-flow enters the check valve apparatus (7) that is made of a funnel shape device and spherical object, the jack-up spherical object through air outlet hole (6), through filter (8), export through pneumatic tube (9).
Piston continues to move downward, and touches lubricating fitting (10), and piston is lubricated, because air outlet hole (6) is in lubricating fitting (9) top, lubricant oil is difficult for the air-flow ejection, a spot of oil content during through filter (8), is filtered.
When piston moves upward, the round of check valve apparatus (7) the funnel shape device that falls back.
Claims (5)
1, a kind of manual inflation's instrument, the artificial push-and-pull piston of this instrument utilization (4) makes its to-and-fro motion in cylinder body, produces air pressure, the compressing air-flow is exported through air outlet hole, it is characterized in that in cylindrical shell (1) bottom, is provided with a lubricating fitting (10) that is made of the hygroscopic materials that soaks into lubricant oil.
2, instrument according to claim 1 is characterized in that contacting with this lubricating fitting (10) when piston (4) moves to cylindrical shell (1) bottom.
3, instrument according to claim 1 is characterized in that being positioned at lubricating fitting (10) top at air outlet hole (6).
4,, it is characterized in that the gas delivery part outside air outlet hole (6) is provided with check valve apparatus (7) according to claim 1.2 or 3 described instruments.
5,, it is characterized in that the gas delivery part outside air outlet hole (6) is provided with filter (8) according to claim 1.2 or 3 described instruments.
