Abstract
A manual inflator relates to an inflator which consists of a connection rod mechanism composed of a stand, a handle, a connection rod and a lower pressure arm through a fixing shaft and a rotation shaft. The inflator is characterized in that an LCD display screen which displays the tyre pressure value of tyres is arranged above the stand; the surroundings of the LCD display screen are sealed with the stand through a rubber sealing surface; a through round hole is arranged in the stand; one end of the round hole is an air inlet, and the other end is a socket for connecting an air inflation rubber tube; and a valve device used for controlling the one-way flow of air is arranged between the air inlet and the socket. The utility model has the advantages of simple structure, portability and easy operation. Besides, the LCD display screen on the upper part can well display the pressure of the tyres, therefore, the inflator can decide whether air inflation or air exhaust is carried out according to the pressure requirements of different tyres.
Description
The technology neighborhood:
The utility model relates to inflator, specifically is to be used for manual inflator that air tube is inflated.
Background technique:
At present, present car owners mainly are use air compressor for the method for air tube inflation, but we can find that in use the volume of air compressor is big, and Xiang concerning the cost height, carry very inconvenience.For ordinary family, be difficult to meet the demands, so air compressor mainly is present in the Auto repair shop.
We analyze in to the traffic accident on the expressway and can draw in addition, traffic accident betide pressure of tire unbalanced very big relation arranged, and when in Auto repair shop, inflating at present with air compressor, the pressure gauge that shows for the size of the pressure in the tire is pointer, the problem one of Cun Zaiing is that pressure needs oneself to convert like this, the 2nd, be difficult to read accurate data.How to solve promptly and can inflate easily, be easy to carry, inflator that again can accurate reading seems particularly important.
Summary of the invention:
Technical problem to be solved in the utility model provides a kind of be easy to carry, make things convenient for inflation and easy-to-read manual inflator.
The utility model wants the technical solution problem to be achieved through the following technical solutions:
A kind of manual inflator, the linkage mechanism of being made up of by stationary axle and rotating shaft support, handle, connecting rod and following pressure arm constitutes, it is characterized in that: above support, be provided with LCD display, demonstrate the tire pressure value of tire on the LCD display, described LCD display around by sealing between rubber front cover and the support.Have a circular hole that runs through in described base inner, an end of circular hole is a suction port, and an end is provided with the one-way flow that valving is used for control gaseous for connecting the socket of inflation sebific duct between described suction port and socket.
Described LCD display is provided with reset key and backlight on ﹠ off switch, is used to set the initial pressure and the demonstration backlight of manual inflator.
The beneficial effects of the utility model are simple in structure, are easy to carry, and easy operating, the LCD display on top can well demonstrate the pressure of tire, thereby determines whether inflate and exit according to different tire pressure demands.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a plan view of the present utility model;
1-support, 2-handle, 3-connecting rod, 4-following pressure arm, 5-stationary axle, 6-rotating shaft,
7-display screen, 8-circular hole, 9-suction port, 10-valving, 11-socket,
12-inflation sebific duct, 13-rubber front cover.
Embodiment:
Reaching embodiment below with reference to the accompanying drawings is described further the utility model:
As Fig. 1, shown in 2, a kind of manual inflator, by support 1, handle 2, the linkage mechanism that connecting rod 3 and following pressure arm 4 are formed by stationary axle 5 and rotating shaft 6 constitutes, above support, be shaped on the groove that caves inward, a tetragonal LCD display 7 is installed in the groove, pass through sealing and fixing between rubber front cover 13 and the support 1 around the display screen 7, the inside of handle 2 is shaped on the circular hole 8 that runs through support, the end that hand grips is a suction port 9, mounted valve device 10 in the suction port 9, the other end leads to the air outlet, and air outlet external spiral mounting receptacle 11 is tightly connected with the inflation sebific duct 12 that is connected the automobile tire gas nozzle cap on the socket 11.
In use, remove the cranked tire valve cap, the inflation sebific duct 12 of inflator is aimed at cranked tire valve, and press down fast, guarantee good seal between the two simultaneously, be not as the criterion to hear gas leakage sound, this moment, the tire pressure value was presented on the LCD immediately, read LCD and went up the tire pressure value that shows; Determine inflation or venting again according to different tire pressure demands.When the measured value error is excessive, use reset key to make zero, make the value of measurement more accurate, preserve zero point at that time after making zero by reset key automatically, till next zero clearing at every turn.Press the back of the body button of turning off the light at the dark place, the bright readability of backlight extinguishes in second automatically at 3-5, reopens backlight by this key again.
Power supply comes from battery in the utility model, and battery is selected CR2450,2.4-3.6VDC, and when voltage was lower than 2.4V, start can show LO and then enter the measurement state, and upper left side low pressure symbol constantly glimmers, and reminded the user will change battery.Measuring range 0-7BAR (between 0-100PSI), under the normal temperature environment error be ± 0.2BAR (± 3PSI), surpass this range and show actual numerical value but do not guarantee precision that when air pressure surpassed 17BAR (250PSI), LCD showed.
More than show and described basic principle of the present utility model and technical characteristics and major advantage.The technician of the industry can understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all should fall in the claimed scope of the present utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
