Abstract
The utility model relates to an inflation pressure measuring device of a buffer. The inflation pressure measuring device mainly comprises a barometer, a three-way pipe, an inflatable nozzle, an air source joint, an air source blocking cover and a hose, wherein the inflatable nozzle mainly comprises a shell, a blocking cover, a joint, an ejector rod, a nut, a screw, a handle and a sealing piece; the nut is in threaded connection with the rear part of the shell; the screw is in threaded connection with the nut and penetrates through the nut; the ejector rod is positioned in the shell; the rear part of the ejector rod is connected with the screw which is connected with the handle; a key groove is arranged at the middle part of the ejector rod; and a pin hole is formed in the middle position of the shell and is internally provided with a pin. The inflation pressure measuring device has the advantages that the ejector rod is pushed to slide by utilizing rotation of the screw so as to eject a buffer joint for charging air, and the key groove of the ejector rod and the pin are used for guiding the ejector rod to slide, so that the damage to the buffer joint and the inflatable nozzle when the handle rotates is reduced and avoided, the service life of the buffer is prolonged, and the use performance of equipment is improved. The inflation pressure measuring device is used for inflation pressure measurement of the buffer of an airplane.
Description
Technical field
The utility model belongs to the inflation pressure-detecting device that the sensing equipment technical field relates to a kind of buffer.
Background technique
Buffer is widely used in the system of reciprocating pump outlet equal pressure fluctuation; Play the steady pressure effect, its inflation pressure has certain rating value, and is a certain amount of if air bag inflation pressure is lost to; Buffer will lose original effect; So the inflation of buffer and the mensuration of pressure just seem particularly important, at present domestic charger inflation push rod on the market all is a rotary structure, very easily damages buffer interface and charging air inlet.
Summary of the invention
For overcoming the deficiency of above-mentioned existing technology, the utility model provides a kind of buffer inflation pressure-detecting device, to improve the performance of buffer pressure-detecting device, avoids damaging charging air inlet and buffer interface.
The utility model buffer inflation pressure-detecting device mainly comprises barometer, three-way pipe, charging air inlet, gas source connector, source of the gas blanking cover and flexible pipe.Charging air inlet mainly comprises housing, blanking cover, joint, push rod, nut, screw rod, handle and Sealing.Nut is connected with the rear threads of housing, and screw rod is connected with nut thread and passes nut, and push rod is positioned at housing, and the rear portion of push rod is connected with screw rod, and screw rod is connected with handle.The middle part of push rod has keyway, and the neutral position of housing is provided with pin-and-hole, and pin (19) is housed in the pin-and-hole.
The binding site of housing and joint is provided with 5～20 steel balls, and is so that the joint rotation flexibly, for convenience detach.Sealing comprises sealing gasket, packing ring and seal ring.
On the push rod of inflation pressure-detecting device, spline, after push rod is packed housing into, be screwed into pin; Keyway is slidingly matched on pin and the push rod; When handle with sleeve, push rod backs down buffer interface and charges into gas along the pin linear slide; Pinned guiding and position-limiting action avoid the use of in the process push rod and rotate with handle and damage buffer interface and charging air inlet.Joint and housing adopt the fit of a plurality of steel balls, are coated with lubricating grease when steel ball is installed, and joint rotates flexibly, convenient disassembly.
The utility model utilizes screw rod rotate to promote push rod and slides, and reduces and avoids damaging buffer interface and charging air inlet, has prolonged the life-span of pressure-detecting device, has improved the usability of equipment.The utility model outward appearance is small and exquisite, simple to operate, economical and practical, do not damage equipment, can be used for the inflation pressure measurement of aircraft buffer.
