Detailed description of the invention
Below in conjunction with detailed description of the invention, the present invention is further illustrated.Wherein, accompanying drawing only for exemplary illustration, expression be only schematic diagram, but not pictorial diagram, can not be interpreted as the restriction to this patent; In order to better embodiments of the invention are described, some parts of accompanying drawing have omission, zoom in or out, and do not represent the size of actual product; For a person skilled in the art, in accompanying drawing, some known features and explanation thereof may be omitted is understandable.
Be 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, this inflating jack comprises air bag 10, air bag 10 is provided with valve assembly 20, valve assembly 20 comprises the valve 21 be fixedly installed on air bag 10, for covering gas nozzle cap 22 outside valve 21 and for coordinating fixing gas-guiding structure 23 with gas nozzle cap 22, be provided with through hole 211 in the middle part of valve 21, gas-guiding structure 23 is through through hole 211 and by opening or close valve 21 with the routing motion of gas nozzle cap 22.
The structure of this inflating jack is simple, can directly inflate, and by arranging the gas-guiding structure 23 opening or close valve 21 with gas nozzle cap 22 routing motion, be equivalent to a check valve and leak gas to prevent air bag, then pressing gas-guiding structure 23 can realize when needs are exitted.The inflation of this inflating jack and venting convenient and not easily leak gas, safety factor is high, is suitable for applying.
Wherein, as shown in Figure 2, Figure 4 shows, gas-guiding structure 23 comprises pipe link 231, elastic component 232 and sealing plug 233, sealing plug 233 passes through hole 211 in air bag 10, elastic component 232 to be fixed on through hole 211 and to be set in sealing plug 233 and passes on the outer wall of the part of through hole 211, pipe link 231 is fixedly connected with sealing plug 233 and offsets with elastic component 232, and gas nozzle cap 22 coordinates fixing with pipe link 231.
In the present embodiment, in order to manufacture and easy to use, bolt can be adopted to substitute pipe link 231, and namely it comprises interconnective head 234 and screw rod 235, screw rod 235 inserts and is fixed on sealing plug 233, and head 234 offsets with elastic component 232 and coordinates with gas nozzle cap 22 fixing.
As shown in Figure 2, gas nozzle cap 22 comprises interconnective lid 221 and neck 222, and neck 222 is provided with the groove 223 mated with head 234, and lid 221 is for covering outside valve 21; Seal ring 224 is provided with, to prevent gas leakage further between lid 221 and neck 222.
During actual use, when needs are inflated, directly can inflate from gas nozzle cap 22, because the design of the gas-guiding structure 23 of itself is equivalent to a check valve, therefore can preferably prevent air bag from leaking gas; When needs are exitted, only need press the head 234 of the pipe link 231 (i.e. bolt) matching fixing with gas nozzle cap 22,22, rotary air tap lid can drive pipe link 231 and then drive sealing plug 233 to open and realize venting; Unclamp gas nozzle cap 22, the return effect due to elastic component 232 makes sealing plug 233 again close valve 21, thus prevents gas leakage.
As the improvement of above-described embodiment scheme, the neck 222 of described gas nozzle cap 22 is provided with draw-in groove (sign), described draw-in groove bending structure at a right angle, opening is towards described sealing plug 233, described sealing plug 233 is provided with projection 2331 diametrically, described gas nozzle cap 22 is connected and after rotating to an angle, described projection 2331 is arranged in described draw-in groove, avoids the maloperation of described gas-guiding structure 23 to cause gas leakage with described valve 11.
The gasbag ektexine of the present embodiment is provided with Kev and draws hermetic coating, not fragile, preferably can extend the service life of this inflating jack.In addition, in order to draw materials and easy-to-use, elastic component can use spring.Being understandable that, except using spring, can also be other elastic constructions, as long as can play same effect and result of use.In addition, gasbag ektexine can also arrange handle 11, be convenient to take and move, it is more convenient to use.
Obviously, the above embodiment of the present invention is only for example of the present invention is clearly described, and is not the restriction to embodiments of the present invention.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments.All any amendments done within the spirit and principles in the present invention, equivalent to replace and improvement etc., within the protection domain that all should be included in the claims in the present invention.
