Description
本創作係關於一種能快速切換至高壓打氣模式或一般低壓打氣模式之變壓打氣筒。This creation is about a variable pressure pump that can be quickly switched to high pressure pumping mode or general low pressure pumping mode.
按，目前市售之自行車大致可區分為公路車、越野車及登山車，公路車之輪胎為了降低滾動阻力，所以會打入較高之胎壓(因胎壓越高，則滾動阻力越小)，而越野車及登山車為了能吸收震動，則必須打入較低之胎壓(若胎壓過高，則會失去避震效果)，坊間之打氣筒製造商便開發出可切換打高胎壓(高壓打氣模式)及低胎壓(低壓打氣模式)之打氣筒。
習用變壓打氣筒便如我國第089222988號「變壓力之打氣筒」、第089205218號「可變壓力之打氣筒」、第086207142號「省力及高氣量打氣筒」…等等專利前案所示般，然而，該等專利前案之結構相當複雜，導致加工成本無法有效降低、組裝又甚為複雜、操作也不甚便利。
本創作人有鑑於上揭專利前案之缺點，經不斷構思、創研，乃研發出本創作。
According to the current market, bicycles can be roughly divided into road vehicles, off-road vehicles and mountain bikes. In order to reduce the rolling resistance, the tires of road vehicles will hit a higher tire pressure (the higher the tire pressure, the lower the rolling resistance). In addition, in order to absorb vibration, off-road vehicles and mountain bikes must enter a lower tire pressure (if the tire pressure is too high, the suspension effect will be lost), and the manufacturer of the pump will develop a switchable height. Inflator for tire pressure (high pressure pumping mode) and low tire pressure (low pressure pumping mode).
The conventional variable pressure pump is like the "pressure-inflating pump" of China No. 089222988, the "variable pressure pump" of No. 089205218, the "saving and high-pressure pump" No. 086207142, etc. However, the structure of the patents is quite complicated, resulting in inefficient processing costs, complicated assembly, and inconvenient operation.
In view of the shortcomings of the pre-existing patent case, the creator has developed this creation through continuous conceiving and research.
本創作係提供一種可快速切換之變壓打氣筒，其係於一具有缸孔且能活動之氣缸安裝有後端蓋，用以在缸孔與後端蓋之間界定出一後氣室，後端蓋另設有連通後氣室內外之洩壓孔，以及設有能啟閉洩壓孔之開關閥，以便在開啟洩壓孔時，可以解除後氣室之第二段加壓供氣，使之應用於一般低壓打氣模式。
是以，本創作該等配置，確能大大的簡化了上揭專利前案之結構配置以及組裝複雜問題，以便在大幅節省工時與提昇效率下達成符合經濟之原則及新穎功能，進而去除上揭專利前案的不良問題，且能有效地增進操控方便性，確實為變壓打氣筒之新穎技術。
The present invention provides a quick-changeable variable pressure pump which is mounted on a movable cylinder having a rear end cover for defining a rear air chamber between the cylinder bore and the rear end cover. The rear end cover is additionally provided with a pressure relief hole connecting the air chamber inside and outside, and an on-off valve capable of opening and closing the pressure relief hole, so that when the pressure relief hole is opened, the second section of the rear air supply chamber can be released. It is applied to the general low pressure pumping mode.
Therefore, the configuration of the creation can greatly simplify the structural configuration and assembly complexity of the pre-existing patent application, so as to achieve economical principles and novel functions while greatly saving man-hours and improving efficiency, thereby removing the above. Uncovering the problem of the pre-patent case, and effectively improving the convenience of handling, it is indeed a novel technology of the variable pressure pump.
