Description
Technical field
The utility model relates to a kind of air-tightness for detection of nozzle, opening force and/or closes the equipment of power,Relate more specifically to a kind of integrated form nozzle detecting device.
Background technology
Conventionally, the windscreen wiper assembly of automobile includes nozzle 10, and its structure as shown in Figure 1, comprises male joint11, female joint 12 and tube connector 13, under the state of assembling, male joint 11 is connected with water source, and mother connects12 are formed as free end, tube connector 13 between male joint 11 and female joint 12, needs toWhen windshield injection water, current flow to female joint 12 from male joint 11 along tube connector 13,And finally spray by female joint 12. The water spray principle of this nozzle 10 is carried out in conjunction with the structure of female joint 12Brief description, Fig. 2 is the schematic perspective view of female joint 12, Fig. 3 is the profile of female joint 12, motherJoint 12 includes bulb 121, the seat of honour 122, spring 123, fixed block 124, gasket seal 125 HesWater inflow 126, wherein, the seat of honour 122 is fixedly connected with water inflow 126, and bulb 121 is placed in the seat of honourIn 122 ball-and-socket, the top of spring 123 is equipped in the groove of the seat of honour 122, and bottom is against fixed block124, gasket seal 125 is between fixed block 124 and water inflow 126. Under non-water spray state, bulletSpring 123 applies active force down to fixed block 124, thereby forces gasket seal 125 to be posted by into waterPart 126. When needs are during to windshield injection water, current flow from the bottom up, thereby to gasket seal125 apply active force up, and in the situation that hydraulic pressure is enough large, sealing gasket 125 moves up, currentEnter the seat of honour 122 by the gap between sealing gasket 125 and water inflow 126, then via the seat of honour 122 withGap ejection between bulb 121.
Describe by said structure known, because fixed block 124 and gasket seal 125 are only by spring 123Elastic force realize assembling, if deflection appears in spring 123 in assembling process, be easy to cause this sprayMouth 10 leaks sealing gasket 125 places. In order to detect this drainage, conventional package seal checker bagDraw together water pump, water pipe etc., one end of water pipe is connected and carries out water flowing detection with the seat of honour 122 near bulb 121,If testing result shows the end of water inflow 126 and there are flowing out (emitting water), sealing gasket 125 places leakage is describedWater. Obviously, judge whether to emit water to be easy to occur error by naked eyes, some in-problem nozzles10 are installed on automobile, cause user's complaint.
In addition, describe knownly by said structure, after assembling completes, the size of spraying hydraulic pressure depends onThe opening force of nozzle and/or close power, opening force and/or the power of closing depend on opens the required hydraulic pressure of nozzleThe elastic force of (current are washed the hydraulic pressure of nozzle open) and spring. If opening force is low, just representative need to be openedThe hydraulic pressure of nozzle is low, and like this, hydraulic pressure just can be washed nozzle very like a cork open, if opening force is too low,Nozzle is just sprayed water and will be caused drainage in the situation that having point pressure a little. If the power of closing is high, with regard to generationThe hydraulic pressure that table need to be opened nozzle is high, and like this, current are difficult to wash open nozzle. Existing nozzle productThe quality nozzle manufacturing process that places one's entire reliance upon itself, before assembling not to opening force and/or close powerDetect, thereby cause product quality uneven, cause user's complaint.
