Description

可轉換握把方向的打氣筒Pump with switchable grip direction

本發明主要係揭示一種打氣筒，尤指一種可轉換握把方向的打氣筒。 The invention mainly discloses a pump, in particular a pump capable of changing the direction of a grip.

一般打氣筒通常會具有能夠在汽缸內進行往復移動的活塞桿，以壓縮空氣而進行打氣作業。為便於使用者進行打氣作業，一般打氣筒皆會於活塞桿穿出於汽缸外的一端上設置橫向的握把，且橫向的握把與活塞桿互相垂直，使握把與活塞桿整體大致上呈T字形的配置，而提供使用者較適當的施力方式。 Generally, an air pump usually has a piston rod capable of reciprocating in a cylinder to perform air pumping operation by compressing air. In order to facilitate the user's pumping operation, generally, the pump is provided with a horizontal grip on the end of the piston rod that is out of the cylinder, and the horizontal grip and the piston rod are perpendicular to each other, so that the grip and the piston rod as a whole are roughly The T-shaped configuration provides users with a more appropriate way of applying force.

然而上述橫向握把與活塞桿互相垂直，將使得打氣筒整體的最大寬度會因為橫向握把而明顯加寬，導致無論攜帶或收納皆會佔用過多空間，使用上有便利性較為不佳的問題。 However, the above-mentioned horizontal grip and the piston rod are perpendicular to each other, which will make the overall maximum width of the inflator significantly wider due to the horizontal grip, resulting in taking up too much space whether it is carried or stored, and it is not easy to use. .

因此，目前有一種具有可收折握把的打氣筒，其能將握把相對活塞桿樞轉，故在非打氣作業時能夠將握把樞折至與活塞桿同一軸向，減少打氣筒整體的寬度，以期增進攜帶或收納的便利性。但此種具有可收折握把的打氣筒，由於握把僅能夠在與活塞桿樞接處進行樞擺，故雖然將握把樞折至與活塞桿同一軸向能減少打氣筒整體的寬度，但握把收折後確增加打氣筒整體軸向的長度，對於攜帶或收納仍不具便利性。 Therefore, at present, there is a pump with a foldable grip, which can pivot the grip relative to the piston rod. Therefore, during non-pumping operations, the grip can be pivoted to the same axial direction as the piston rod to reduce the overall volume of the pump. To increase the convenience of carrying or storage. However, this type of inflator with a foldable grip can be pivoted only at the pivot joint with the piston rod. Therefore, although the grip is pivoted to the same axial direction as the piston rod, the overall width of the inflator can be reduced. However, the folded handle does increase the overall axial length of the pump, which is not convenient for carrying or storing.

再者，上述具有可收折握把的打氣筒，握把無論於非打氣作業或打氣作業時均未有能夠與活塞桿相對固定定位的結構，尤其在打氣作業時，握把極易因使用者施力而隨意相對活塞桿擺動，進而影響打氣作業的效率。 Furthermore, the above-mentioned inflator with a foldable grip has no structure capable of being relatively fixedly positioned with the piston rod in the non-inflating operation or in the inflating operation, especially during the inflating operation, the handle is extremely easy to use due to The force is applied to swing relative to the piston rod, which affects the efficiency of the pumping operation.

有鑑於上述先前技術的問題無法有效的解決與克服，因此本申請人提出本專利申請，以解決前述問題點。 In view of the fact that the above-mentioned problems of the prior art cannot be effectively solved and overcome, the applicant filed this patent application to solve the foregoing problems.

本發明可轉換握把方向的打氣筒所要解決的技術問題在於：習知打氣筒無法有效地縮小體積，且習知具有可收折握把的打氣筒，因其握把任意相對活塞桿樞擺，而導致打氣作業效率不佳。 The technical problem to be solved by the pump capable of changing the grip direction of the present invention is that the conventional pump cannot effectively reduce the volume, and the pump with a retractable grip is conventionally known, because its grip is pivoted relative to the piston rod , Resulting in inefficient pumping operations.

因此，本發明提供一種可轉換握把方向的打氣筒，其包括一個汽缸單元與一個握把單元，該汽缸單元具有一個第一軸線，該握把單元包括一個連接於該汽缸單元的定位件與一個能夠相對該定位件滑移並樞擺的握把件，該定位件包括一個第一滑移部，該第一滑移部具有一個與該第一軸線相交的第二軸線，該握把件包括一個可移動地連接該第一滑移部的第二滑移部、一個第二卡接部以及一個第三卡接部，該第二卡接部與該第三卡接部選擇性地與該定位件互相連接。 Therefore, the present invention provides a pump with a switchable grip direction, which includes a cylinder unit and a grip unit, the cylinder unit has a first axis, and the grip unit includes a positioning member connected to the cylinder unit and A grip member capable of sliding and pivoting relative to the positioning member, the positioning member includes a first sliding portion having a second axis intersecting the first axis, and the grip member The second sliding portion includes a second sliding portion movably connected to the first sliding portion, a second engaging portion and a third engaging portion. The second engaging portion and the third engaging portion are selectively connected with the third engaging portion. The positioning members are connected to each other.

該握把件能夠沿平行該第一軸線的方向相對該定位件滑移而於第一位置與第二位置之間變換，當該握把件位於第一位置，該第二卡接部連接該定位件，當該握把件位於第二位置，該第二卡接部脫離該定位件。 The grip member can slide relative to the positioning member in a direction parallel to the first axis to change between a first position and a second position. When the grip member is in the first position, the second latching portion is connected to the The positioning member, when the grip member is located at the second position, the second engaging portion is disengaged from the positioning member.

該握把件還能夠以該第二軸線相對該定位件樞擺而於第二位置與第三位置之間變換，當該握把件位於第三位置，該第三卡接部連接該定位件。 藉此，該握把件能夠在第一位置、第二位置以及第三位置之間轉換方向，以達成縮小體積，以及避免該握把件任意地相對該定位件樞擺的功效。 The grip member can also be pivoted relative to the positioning member by the second axis to change between the second position and the third position. When the grip member is located in the third position, the third latching portion is connected to the positioning member. . Thereby, the grip member can switch directions between the first position, the second position, and the third position, so as to achieve a reduction in volume and avoid the effect that the grip member is arbitrarily pivoted relative to the positioning member.
