具体实施方式 detailed description
下面结合附图对本发明做进一步说明。  The invention will be further described below in conjunction with the accompanying drawings.
如图 1、 2、 3和 4所示为本发明吸尘器接头组件的一种实施方式的示意图， 包括第一接 头、 卡圈和第二接头， 所述第一接头是与吸尘器主体上的吸尘口相配接的吸口接头， 所述吸 口接头 1的端部 15上设有锁扣 151， 吸口接头 1通过锁扣 151与吸尘器主体上的吸口相配接 (图中未示出）。 吸口接头 1另一端设有卡槽 13， 卡槽 13为环形且环绕在吸口接头 1外表面 14。 卡槽 13内还设有卡口 12， 优选设置两个卡口 12， 两个卡口 12相对设置。 卡槽 13具有 配合面 131， 配合面 131是指外表面 14在卡槽 13内的部分， 配合面 131的半径为 R 。 吸口 接头 1上设有按钮槽 11， 按钮槽 11可收容按钮 31， 按钮槽 11与卡槽 13相连接。 所述卡圈 3成 C形且可套设在卡槽 13中。 卡圈 3包括两个相对设置的臂形部 34， 臂形部 34具有内壁 341， 当卡圈位于卡槽 13中时， 内壁 341能够与所述配合面 131贴合（如图 3所示）。 臂形部 34—端设有卡勾 32， 卡勾 32能够穿过卡口 12且能够卡住第二接头。 臂形部 34之间通过连 接部 33相连， 连接部 33为弧形， 连接部 33的半径为 r (具体的， 指连接部内壁 331轮廓的 半径）， 且 r<R。 连接部 33上方设有按钮 31， 按钮 31具有主体 311， 主体 311表面具有一 定面积且表面具有适度凹陷， 使得用户更容易用手指按压操作。 所述按钮 31具有按压行程， 按压行程是按钮 31与配合面 131之间的间隙 133， 间隙 133的最大间距为 H， 间距 H为按钮 下部与吸口接头配合面 131之间的最大距离， 因此所述按钮 31的最大按压行程即为 H， 按钮 31具有按压行程使得按钮被按压时能够向下运动， 如图 4所示， 当按钮向下运动， 卡圈臂形 部 34受到吸口接头外表面 14的作用力而沿卡圈径向张开， 卡勾 32从软管接头 2的凹槽 21 内脱出 （参看图 8)， 此时可将吸口接头 1和软管接头 2分离。 本领域技术人员可知， 按钮的 按压行程可以通过其他结构获得， 例如按钮与配合面 131贴合， 然后在配合面 131上开口， 此种方式同样能够使按钮向下按压， 使得臂形部受力张开。 因此， 只要按钮 31在竖直方向能 够运动， 就满足具有按压行程。 所述按钮、 臂形部和连接部是一体的， 卡圈 3是由具有形变 能力的材料制成， 本实施例中优选为塑料。 所述第二接头为软管接头 2， 软管接头一端与软 管 22相连接， 软管接头 2上设有凹槽 21， 凹槽 21环绕在软管接头外部。 接头组件装配在一 起时，卡圈卡勾 32穿过卡口 12且卡在凹槽 21内，使得吸口接头和软管接头在轴向无法脱开， 同时吸口接头和软管接头可相对转动， 当然， 吸口接头和软管接头也可以是不能转动的连接 结构。 本领域技术人员可知， 所述凹槽 21可以只是挡边 211 (参看图 8)， 同样可以做到使吸 口接头和软管接头无法在轴向脱开。 1, 2, 3 and 4 are schematic views of an embodiment of a vacuum cleaner connector assembly according to the present invention, including a first joint, a collar and a second joint, the first joint being vacuumed on the main body of the cleaner The port end fitting 15 is provided with a latch 151. The mouthpiece connector 1 is coupled to the suction port on the cleaner body through a latch 151 (not shown). The other end of the mouthpiece connector 1 is provided with a card slot 13 which is annular and surrounds the outer surface 14 of the mouthpiece connector 1. The card slot 13 is further provided with a bayonet 12, preferably two bayonet ports 12 are provided, and the two bayonet ports 12 are oppositely disposed. The card slot 13 has a mating surface 131. The mating surface 131 refers to a portion of the outer surface 14 in the card slot 13. The mating surface 131 has a radius R. The mouthpiece connector 1 is provided with a button slot 11, and the button slot 11 can accommodate the button 31, and the button slot 11 is connected to the card slot 13. The collar 3 is C-shaped and can be sleeved in the card slot 13. The collar 3 includes two oppositely disposed arm portions 34. The arm portion 34 has an inner wall 341. When the collar is located in the slot 13, the inner wall 341 can be engaged with the mating surface 131 (as shown in FIG. 3). . The end of the arm portion 34 is provided with a hook 32, and the hook 32 can pass through the bayonet 12 and can catch the second joint. The arm portions 34 are connected by a connecting portion 33 which is curved, and the radius of the connecting portion 33 is r (specifically, the radius of the contour of the inner wall 331 of the connecting portion), and r < R. A button 31 is provided above the connecting portion 33, and the button 31 has a main body 311 having a certain surface and a surface having a moderate recess so that the user can more easily perform a finger pressing operation. The button 31 has a pressing stroke, and the pressing stroke is a gap 133 between the button 31 and the mating surface 131. The maximum spacing of the gap 133 is H, and the spacing H is the maximum distance between the button lower portion and the mouthpiece fitting surface 131. The maximum pressing stroke of the button 31 is H, and the button 31 has a pressing stroke so that the button can be moved downward when pressed, as shown in Fig. 4, when the button is moved downward, the collar arm portion 34 is subjected to the suction joint outer surface 14 The force is released radially along the collar, and the hook 32 is disengaged from the recess 21 of the hose joint 2 (see Fig. 8), at which point the nozzle joint 1 and the hose joint 2 can be separated. It can be known to those skilled in the art that the pressing stroke of the button can be obtained by other structures, for example, the button is engaged with the mating surface 131 and then opened on the mating surface 131. In this way, the button can also be pressed downward, so that the arm portion is stressed. Open. Therefore, as long as the button 31 is movable in the vertical direction, it is satisfied to have the pressing stroke. The button, the arm portion and the connecting portion are integrated, and the collar 3 is deformed by Made of a material of capability, preferably plastic in this embodiment. The second joint is a hose joint 2, one end of which is connected to the hose 22, and the hose joint 2 is provided with a groove 21, and the groove 21 surrounds the hose joint. When the joint assembly is assembled, the collar hook 32 passes through the bayonet 12 and is caught in the recess 21, so that the suction joint and the hose joint cannot be disengaged in the axial direction, and the suction joint and the hose joint can be relatively rotated. Of course, the mouthpiece connector and the hose connector may also be non-rotatable connection structures. It will be apparent to those skilled in the art that the recess 21 can be only the rib 211 (see Fig. 8), and the suction joint and the hose joint cannot be disengaged in the axial direction.
如图 5、 6、 7和 8所示， 卡圈 3的臂形部具有内壁 341， 卡勾 32具有内侧壁 323， 内侧 壁 323与通过卡圈圆心 0的直径夹角 α大于 3度， 所述圆心 0为臂形部内壁 341所在圆的圆 心， 其作用在于防止吸口接头 1和软管接头 2相互旋转过程中， 卡勾 32受切向力使吸口接头 和软管接头松脱。 卡勾 32具有侧壁 322， 侧壁 322具有大于 CO. 5的导向斜角或者 R0. 5的圆 角， 因此在将吸口接头 1和软管接头 2装配在一起时， 不需要按压卡圈按钮， 即当软管接头 2插入吸口接头 1过程中， 软管接头 2与卡勾 32侧壁 322接触时， 卡勾 32受到沿半径方向 向外的力，因此卡圈 3会张开从而卡勾 32卡入凹槽 21， 由于凹槽 21环绕在软管接头 2外部， 因此软管接头 2插入吸口接头 1时不需要调整角度， 卡圈 3将吸口接头 1和软管接头 2配接 在一起， 吸口接头 1和软管接头 2在轴向固定。 由于设有软管接头上设有凹槽 21， 吸口接头 1可与软管接头 2相对转动， 从而使用户更方便得操作软管。 如果需要使吸口接头 1和软管 接头 2脱开， 只要按压卡圈 3上的按钮 31， 卡圈 3形变使得卡勾 32与凹槽 21脱开， 此时可 拔出软管接头 2。  As shown in FIGS. 5, 6, 7, and 8, the arm portion of the collar 3 has an inner wall 341, and the hook 32 has an inner side wall 323, and the inner side wall 323 has an angle α greater than 3 degrees with the diameter of the center 0 of the collar. The center 0 of the circle is the center of the circle where the inner wall 341 of the arm portion is located, and its function is to prevent the hook 32 from being detached by the tangential force during the rotation of the mouthpiece joint 1 and the hose joint 2. The hook 32 has a side wall 322, and the side wall 322 has a guide angle larger than CO. 5 or a rounded corner of R0. 5, so when the suction joint 1 and the hose joint 2 are assembled together, there is no need to press the collar button. That is, when the hose connector 2 is inserted into the mouthpiece connector 1, when the hose connector 2 is in contact with the side wall 322 of the hook 32, the hook 32 receives a force outward in the radial direction, so the collar 3 is opened and the hook is hooked. 32 snaps into the groove 21, since the groove 21 surrounds the outside of the hose joint 2, the hose joint 2 does not need to be adjusted when inserted into the mouthpiece joint 1, and the collar 3 mates the mouthpiece joint 1 and the hose joint 2 together The suction joint 1 and the hose joint 2 are fixed in the axial direction. Since the hose connector is provided with a recess 21, the mouthpiece connector 1 can be rotated relative to the hose connector 2, thereby making it easier for the user to operate the hose. If it is necessary to disengage the mouthpiece connector 1 and the hose connector 2, as long as the button 31 on the collar 3 is pressed, the collar 3 is deformed so that the hook 32 is disengaged from the recess 21, and the hose connector 2 can be pulled out.
如图 9和 10所示为本发明第二实施例， 本实施例与前述实施方式的区别在于卡圈结构不 同， 卡圈 3 ' 具有弧线臂 34' ， 弧线臂 34' 至少有部分能够卡入吸口接头上的卡口 12 ' ， 此 时同样可以将吸口接头和软管接头卡接在一起。 所述  9 and 10 show a second embodiment of the present invention. The difference between this embodiment and the foregoing embodiment is that the collar structure is different, the collar 3' has an arc arm 34', and at least a portion of the arc arm 34' can Snap into the bayonet 12' on the suction connector, and the suction connector and the hose connector can also be snapped together. Said
当按压按钮 31 ' ， 弧线臂 34' 从卡口 12 ' 中退出， 吸口接头和软管接头可分离。  When the button 31 ' is pressed, the arc arm 34' is withdrawn from the bayonet 12', and the mouthpiece connector and the hose connector are detachable.
本发明结构简单， 不需要使用其他工具就能够快速组装和拆卸接头组件， 方便用户操作。 任何不脱离本发明构思的结构都在本发明的保护范围内。  The invention has a simple structure and can quickly assemble and disassemble the joint assembly without using other tools, and is convenient for the user to operate. Any structure that does not depart from the inventive concept is within the scope of the invention.
