Specific implementation mode
The present invention is further illustrated With reference to embodiment.Wherein, attached drawing only for illustration,
What is indicated is only schematic diagram rather than pictorial diagram, should not be understood as the limitation to this patent；Reality in order to better illustrate the present invention
Example is applied, the certain components of attached drawing have omission, zoom in or out, and do not represent the size of actual product；To those skilled in the art
For, the omitting of some known structures and their instructions in the attached drawings are understandable.
It is the embodiment of inflating jack of the present invention as shown in Figures 1 to 4.As shown in Figure 1, Figure 2, Figure 4 shows, the inflation is very heavy
Top includes air bag 10, and air bag 10 is equipped with gas nozzle component 20, gas nozzle component 20 including be fixedly installed on air bag 10 gas nozzle 21,
Gas nozzle cap 22 outside gas nozzle 21 is closed for covering and for coordinating fixed gas-guiding structure 23,21 middle part of gas nozzle with gas nozzle cap 22
Equipped with through-hole 211, gas-guiding structure 23 passes through through-hole 211 and by opening or closing gas nozzle 21 with resultant motion with gas nozzle cap 22.
The structure of the inflating jack is simple, can directly inflate, and opens or seals with resultant motion with gas nozzle cap 22 by setting
It holds one's breath the gas-guiding structure 23 of mouth 21, is equivalent to a check valve to prevent air bag gas leakage, air guide knot is then pressed when needing the when of deflating
Structure 23 can be realized.The inflation and deflation of the inflating jack facilitate and are not easy gas leakage, and safety coefficient is high, is answered suitable for promoting
With.
Wherein, as shown in Figure 2, Figure 4 shows, gas-guiding structure 23 includes connecting rod 231, elastic component 232 and sealing-plug 233, close
Blocking 233 is pierced by through-hole 211 out of air bag 10, elastic component 232 be fixed on through-hole 211 and be set in sealing-plug 233 be pierced by it is logical
On the outer wall of the part in hole 211, connecting rod 231 is fixedly connected with sealing-plug 233 and offsets with elastic component 232, gas nozzle cap 22
Coordinate with connecting rod 231 and fixes.
In the present embodiment, in order to manufacture and easy to use, bolt may be used and substitute connecting rod 231, i.e., it includes mutual
The head 234 of connection and screw rod 235, screw rod 235 are inserted and fixed in sealing-plug 233, and head 234 offsets with elastic component 232
And coordinates with gas nozzle cap 22 and fix.
As shown in Fig. 2, gas nozzle cap 22 includes the lid 221 being connected with each other and neck 222, neck 222 is equipped with and head
234 matched grooves 223, lid 221 are closed for covering outside gas nozzle 21；Sealing ring is equipped between lid 221 and neck 222
224, to further prevent gas leakage.
In actual use, it when needing inflation, can be directly inflated from gas nozzle cap 22, due to the gas-guiding structure of itself
23 design is equivalent to a check valve, therefore can preferably prevent air bag gas leakage；When needing to deflate, need to only press and gas nozzle
Lid 22 matches the head 234 of fixed connecting rod 231 (i.e. bolt), and rotary air tap lid 22 then can drive connecting rod 231 in turn
It drives sealing-plug 233 to open and realizes deflation；Gas nozzle cap 22 is unclamped, since the return effect of elastic component 232 makes sealing-plug 233 again
Gas nozzle 21 is closed, to prevent gas leakage.
As the improvement of above-described embodiment scheme, the neck 222 of the gas nozzle cap 22 is equipped with card slot (not indicating), the card
Slot bending structure at a right angle, opening are equipped with convex block 2331, make institute radially towards the sealing-plug 233, the sealing-plug 233
It states after gas nozzle cap 22 connect and rotate by a certain angle with the gas nozzle 11, the convex block 2331 is located in the card slot, avoids institute
The maloperation for stating gas-guiding structure 23 causes gas leakage.
The gasbag ektexine of the present embodiment is equipped with Kev and draws hermetic coating, is hardly damaged, can preferably extend the inflation thousand
The service life on jin top.In addition, in order to draw materials and easy-to-use, elastic component can use spring.It is understood that in addition to making
With spring, other elastic constructions are can also be, as long as can play the same role and using effect.In addition, outside air bag
Handle 11 can also be set on wall, and convenient for taking and moving, use is more convenient.
Obviously, the above embodiment of the present invention be only to clearly illustrate example of the present invention, and not be pair
The restriction of embodiments of the present invention.For those of ordinary skill in the art, may be used also on the basis of the above description
To make other variations or changes in different ways.There is no necessity and possibility to exhaust all the enbodiments.It is all this
All any modification, equivalent and improvement etc., should be included in the claims in the present invention made by within the spirit and principle of invention
Protection domain within.
