Abstract
The utility model discloses an inflator with controllable air pressure, which comprises a handle, an inflating rod, a cylinder, an air conveying pipe and a fixed clamp. The handle is connected to the top of the inflating rod, the other end of the inflating rod is provided with a piston; the piston is positioned in the cylinder; one end of the air conveying pipe is connected to the upper part of a right-side cannikin of the cylinder body; a pressure sensor and an air pressure switch are arranged in the right-side cannikin; a semicircular dial is arranged on the surface of the right-side cannikin; a pointer is arranged on the dial; and the fixed clamp is connected to the other end of the air conveying pipe. The inflator with controllable air pressure is simple in structure and convenient to use, the air pressure in an inflating tire is monitored by the pressure sensor to control the air pressure switch to be opened and closed, so the bad situation caused by the overhigh or overlow air pressure in the tire can be prevented.
Description
Technical field:
The utility model relates to daily inflation field, more specifically to the controlled pump of a kind of air pressure.
Background technique:
The common single piston plus-pressure structure of the general employing of manual pump design; The inflating rod that setting can be twitched back and forth in the pump; The end of inflating rod is provided with a rubber ring seat piston, and pump connects object to be inflatable (being generally vehicle tyre) with the terminal air outlet adapter of air pipe, with drawing on the inflating rod; Make pump inside produce negative inspiratory pressure; Press down inflating rod again, utilize the air pressurized of the piston of inflating rod bottom, pressurized air is charged into through conduit from the air outlet be inflated thing pump inside.Repeatable operation is accomplished until inflation.This mode of inflating exist a problem be exactly the pressure of at every turn squeezing into tire be uncertain; Do not know when to be only a saturated aeration quantity; Can detect the pump be inflated the pressure in the thing if can provide a kind of, such just can prevent to charge into be inflated thing gas too much or the very few and generation unfavorable condition that causes.
The model utility content:
The purpose of the utility model is exactly the deficiency to existing technology; And provide a kind of air pressure controlled pump; Simple in structure; Easy to use, control the switch of baroswitch through the monitoring of pressure transducer air exercise pneumatic tyre internal air pressure, the generation of the unfavorable condition that can prevent to cause because the tire internal air pressure is too high or too low.
The technological solution of the utility model is following:
The pump that a kind of air pressure is controlled; Comprise that handle, inflating rod, cylindrical shell, pneumatic tube reach fixedly clip; Said handle one end is connecting the top of inflating rod, and an end of pneumatic tube is connected in the right side canister of cylindrical shell, and fixedly clip is connected an other end of pneumatic tube.
An other end of said handle is fixed with a piston, and piston closely contacts with cylindrical shell.
Be provided with a pressure transducer and a baroswitch in the canister of said right side, pressure transducer and baroswitch overlap, and pressure transducer is positioned at the top of baroswitch.
Said right side canister upper surface is provided with a fan dial, and dial is provided with a pointer.
Said pressure transducer upper surface center fixation pneumatic tube, and the remaining area of sensor upper surface is connecting fan dial and pointer through circuit.
The beneficial effect of the utility model is:
1, the utility model is simple in structure, and is easy to use, controls the switch of baroswitch through the monitoring of pressure transducer air exercise pneumatic tyre internal air pressure, the generation of the unfavorable condition that can prevent to cause because the tire internal air pressure is too high or too low.
Description of drawings:
Fig. 1 is the whole plan view of the utility model;
Fig. 2 is the partial sectional view of the utility model;
Fig. 3 is the partial enlarged drawing of the a-quadrant of Fig. 2;
Fig. 4 is the plan view of the utility model right side canister.
Among the figure: 10, handle; 20, inflating rod; 30, cylindrical shell; 301, right side canister; 3011, dial; 3012, pointer; 302, pressure transducer; 303, baroswitch; 40, pneumatic tube; 50, fixing clip.
Embodiment:
Embodiment: see that Fig. 1 is to shown in Figure 4; The pump that a kind of air pressure is controlled; Comprise that handle 10, inflating rod 20, cylindrical shell 30, pneumatic tube 40 reach fixedly clip 50; Its said handle 10 1 ends are connecting the top of inflating rod 20, and an end of pneumatic tube 40 is connected in the right side canister 301 of cylindrical shell 30, and fixedly clip 50 is connected an other end of pneumatic tube 40.
An other end of said handle 10 is fixed with a piston 201, and piston 201 closely contacts with cylindrical shell 30.
Be provided with a pressure transducer 302 and a baroswitch 303 in the said right side canister 301, pressure transducer 302 overlaps with baroswitch 303, and pressure transducer 302 is positioned at the top of baroswitch 303.
Said right side canister 301 upper surfaces are provided with a fan dial 3011, and dial 3011 is provided with a pointer 3012.
Said pressure transducer 302 upper surface center fixation pneumatic tube 40, and the remaining area of sensor 302 upper surfaces is connecting fan dial 3011 and pointer 3012 through circuit.
Working principle:
The pump that a kind of air pressure is controlled, through.Pointer 3012 on the dial 3011; Set this air pressure that is inflated in the thing and need what reach; Because the remaining area of sensor 302 upper surfaces is connecting fan dial 3011 and pointer 3012 through circuit; So how many pointers 3012 sets, how many limited signals atmospherically sensor 302 just receives.Grasping handle 10 then inflates; When inflating to a certain degree; Sensor 302 monitors the air pressure that is inflated in the thing through pneumatic tube 40 and reaches the air pressure upper limit that pointer 3012 is set, and baroswitch 303 will be closed, and at this moment the people just inflates and can not get through; It is saturated that the people just knows that be inflated the thing internal air pressure this moment, need not to inflate again.
