Description
本發明係與打氣筒有關,更詳而言之係指一種內藏式壓力計之打氣筒。 The present invention relates to an inflator, and more particularly to an inflator of a built-in pressure gauge.
按,由於騎乘自行車之風氣盛行,因此自行車之相關配件亦發展迅速,目前有一種小型化而便於固定在自行車上之伸縮式打氣筒,便相當受到使用者之喜愛。 According to the popularity of bicycles, the accessories for bicycles have also developed rapidly. At present, there is a telescopic pump that is compact and easy to be fixed on bicycles, which is quite popular among users.
惟,也由於小型化,因此這種便於攜帶之伸縮式打氣筒之功能僅局限在充氣功能。但,由於自行車之輪胎在充氣時必須注意充氣之氣壓大小,以讓自行車能維持在最佳運轉之狀態,因此目前已有業者發展出可同時量測氣壓之打氣筒。此種可量測氣壓之打氣筒不外乎是將壓力錶增設於打氣筒上,但此種方式會增加整體之體積,導致小型化、便於攜帶之功能大打折扣,且直接將壓力錶外露在打氣筒上,亦會導致美觀效果不佳,而顯得突兀,在固定於自行車上時亦較為不易。 However, due to the miniaturization, the function of the portable retractable pump is limited to the inflation function. However, since the tire of the bicycle must pay attention to the air pressure of the inflation when inflating, so that the bicycle can be maintained in an optimal state of operation, a manufacturer has been developed to measure the air pressure at the same time. This kind of measurable air pressure pump is nothing more than adding a pressure gauge to the pump, but this method will increase the overall volume, resulting in a miniaturization, easy to carry the function is greatly reduced, and directly expose the pressure gauge On the pump, it will also lead to poor aesthetics, but it will be awkward and difficult to fix on a bicycle.
有鑑於此,為改善先前技術中,習知打氣筒之壓力錶外露有著會增加整體之體積,導致小型化、便於攜帶之功能大打折扣,及美觀效果不佳、顯得突兀與固定於自行車上較為不易等問題;緣此,本發明乃提供一種內藏式壓力計之打氣筒,其主要包含有:一氣嘴接頭,具有一注氣室、一連接室及一 連通該注氣室與該連接室之導氣孔,該注氣室用以供一氣嘴伸入;一內置管,呈透明,具有一頭端、一尾端及一連結於該頭端與該尾端間之中段,該中段之內部具有一活動容室,該中段之表面具有刻度值,該頭端固定於該氣嘴接頭之連接室內,該頭端上具有一連通至該活動容室之量壓氣孔、一止逆容室及一連通該止逆容室至該頭端外周表面之注氣導孔,該尾端具有至少一連通至外周表面之注氣孔;一內筒,呈透明,該內筒係套疊於該內置管外,一端並與該氣嘴接頭之連接室接合,該內筒另一端具有一進氣孔;一外筒,係套疊於該內筒外,並可受力作用而相對該內筒進行軸向往復位移;一壓力計,係置於該內置管之活動容室內,可於該活動容室內活動位移;一止逆件,當該外筒向外拉移時,該止逆件位於該止逆容室內,並封抵該注氣導孔,使氣嘴內之氣體經由該量壓氣孔進入於該活動容室內,以推動該壓力計位移,以讓使用者可看見該壓力計與該刻度值之相對位置,而得知氣壓大小,當該外筒向內推移時,該止逆件係脫離於該止逆容室外,使該進氣孔、注氣孔、注氣導孔與該導氣孔呈連通狀態而構成一對氣嘴充氣之充氣通道;藉此達到縮減整體之體積、便於攜帶、美觀效果佳及固定容易等功效。 In view of this, in order to improve the prior art, the exposure of the pressure gauge of the conventional pump has an increase in the overall volume, resulting in a miniaturization, a convenient function for carrying, and a poor aesthetic appearance, which is abrupt and fixed on the bicycle. Therefore, the present invention provides a pump for a built-in pressure gauge, which mainly comprises: a gas nozzle joint having a gas injection chamber, a connection chamber and a An air guiding hole connecting the gas injection chamber and the connecting chamber, wherein the gas injection chamber is for inserting a gas nozzle; a built-in tube is transparent, has a head end, a tail end, and a joint end and the tail end In the middle section, the middle section has an activity chamber, the surface of the middle section has a scale value, and the head end is fixed in the connection chamber of the nozzle joint, and the head end has a pressure connected to the movable chamber a gas hole, a stop chamber and an air injection guide hole connecting the check chamber to an outer peripheral surface of the head end, the tail end having at least one gas injection hole communicating with the outer peripheral surface; and an inner tube being transparent, the inner hole The tubular sleeve is sleeved outside the inner tube, and one end is engaged with the connecting chamber of the air nozzle joint, and the other end of the inner cylinder has an air inlet hole; an outer tube is sleeved outside the inner tube and can be stressed Acting and axially reciprocating displacement relative to the inner cylinder; a pressure gauge is placed in the movable chamber of the built-in tube, and can be moved in the movable chamber; a check member, when the outer cylinder is pulled outward The check member is located in the anti-reverse chamber and is sealed against the gas injection guide hole to make the gas nozzle The gas enters the movable chamber through the pressure air hole to push the pressure gauge to be displaced, so that the user can see the relative position of the pressure gauge and the scale value, and the air pressure is determined when the outer tube is moved inward.

是以,上述即為本發明一較佳實施例所提供之一種內藏式壓力計之打氣筒100之各部構件及其組裝方式的介紹,接著再將其使用特點說明如下:當欲使用本發明時,將一輪胎之氣嘴90朝該氣嘴接頭10之注氣室111內伸入(如第三圖所示),並將該扳桿13由鬆放位置扳動至迫緊位置(如第四圖所示),以由該壓注單元12對該氣嘴90進行迫緊,並將該外筒40向外拉移。 Therefore, the above is a description of the components of the pump 100 of the built-in pressure gauge and the assembly manner thereof according to a preferred embodiment of the present invention, and then the use characteristics thereof are as follows: when the present invention is to be used At the same time, the nozzle 90 of a tire is inserted into the injection chamber 111 of the nozzle joint 10 (as shown in the third figure), and the trigger 13 is pulled from the release position to the pressing position (eg, The fourth embodiment is shown to press the nozzle 90 by the injection unit 12 and to pull the outer cylinder 40 outward.
接著,便可持續地將該外筒40進行往復之內外位移伸縮,以使該外筒40內之氣體能經由該內筒30之進氣孔31導入,再經由該注氣孔221而流入該內筒30之內周面與該內置管20之外周面間,並導入於該注氣導孔214內,再經該導氣孔113注入於該注氣室111中,而構成一充氣通道,以對該氣嘴90進行充氣。 Then, the outer cylinder 40 is continuously retracted and retracted so that the gas in the outer cylinder 40 can be introduced through the air inlet hole 31 of the inner cylinder 30, and then flows into the inner portion through the gas injection hole 221. The inner circumferential surface of the cylinder 30 and the outer circumferential surface of the inner tube 20 are introduced into the gas injection guide hole 214, and then injected into the gas injection chamber 111 through the air guiding hole 113 to form an inflation passage. The gas nozzle 90 is inflated.
當該外筒40向內推移時(如第五圖所示),該止逆件60會被推離該止逆容室213,使充氣之作業能順利進行。 When the outer cylinder 40 is pushed inward (as shown in the fifth figure), the check member 60 is pushed away from the check chamber 213, so that the filling operation can be smoothly performed.
當該外筒40向外拉移時(如第六圖所示),該止逆件60則被推入於該止逆容室213內,並封抵該注氣導孔214,以防氣體逆流至該外筒40內。況且,氣嘴90內之氣體會洩出經由該量壓氣孔212而進入於該活動容室231中,以推動該壓力計50之套管52移動,該套管52之移動量視氣體能抵抗多少彈簧54之彈力而定,因此在該外筒40向外拉移時,使用者便能透過呈透明之內筒30及內置管20而看見該指針部521位於該刻度值232之何一位置,便能輕易得知此時該氣嘴90內氣體壓力大小。 When the outer cylinder 40 is pulled outward (as shown in FIG. 6), the check member 60 is pushed into the anti-reverse chamber 213 and sealed against the gas injection guide hole 214 to prevent gas. It flows back into the outer cylinder 40. Moreover, the gas in the gas nozzle 90 will leak out through the pressure air hole 212 and enter the movable chamber 231 to push the sleeve 52 of the pressure gauge 50 to move. The movement amount of the sleeve 52 is resistant to gas. Depending on the spring force of the spring 54, the user can see through the transparent inner cylinder 30 and the inner tube 20 that the pointer portion 521 is located at the scale value 232 when the outer cylinder 40 is pulled outward. The gas pressure in the gas nozzle 90 can be easily known at this time.
藉此,本創作不僅能達到充氣之功效,更能藉由該壓力計50能讓使用者得知氣嘴90內之氣體壓力大小,而達到量壓功效。 In this way, the creation can not only achieve the effect of inflation, but also the pressure gauge 50 can let the user know the gas pressure in the gas nozzle 90, and achieve the pressure effect.
況且,由於本創作之壓力計50採內藏式,不會增加原本之體積,就外觀上而言與一般無壓力計之打氣筒無異,以便於使用者攜帶上之方便。再者,內藏式之壓力計50亦不會造形外觀過於突兀,而能讓本創作固定在腳踏車上時,能具備時尚而流暢之外觀造形,以增進市場上之競爭力。 Moreover, since the pressure gauge 50 of the present invention adopts the built-in type, it does not increase the original volume, and is similar in appearance to the generally non-pressure gauge pump, so that the user can carry it conveniently. Moreover, the built-in pressure gauge 50 does not make the appearance too abrupt, and can make the creation of the creation on the bicycle, can have a stylish and smooth appearance to enhance the competitiveness in the market.
以上所揭,僅為本發明所提供之較佳實施例而已,並非用以限制本發明之實施範圍,凡本技術領域內之相關技藝者根據本創作所為之均等變化,皆應屬本發明所涵蓋之範圍。 The above is only the preferred embodiment of the present invention, and is not intended to limit the scope of the present invention.
