Description
Technical field
The utility model belongs to tire apparatus field, more particularly, to a kind of dual fail-safe outlet piston.
Background technology
Traditional bicycle pump often has two, one is user is inflated using tracheae to bicycle
When due to piston portion it is elastic it is poor can be very laborious, very big strength is paid for the user so that use
Use of the person to tracheae becomes very inconvenient；And another situation is due to then the design defect of outlet piston so that going out for tracheae
Gas effect is poor, so allows for user and inflate each time all squeeze into seldom air, service efficiency is very poor.
The content of the invention
Problem to be solved in the utility model is to provide a kind of dual fail-safe outlet piston, and be especially suitable for user makes to tracheae
User becomes to be more prone to.
In order to solve the above technical problems, the technical solution adopted in the utility model is：A kind of dual fail-safe outlet piston is provided,
Including piston only and leather cup, piston only is cylindrical structure, and the side wall of piston only is provided with mounting groove, piston only
One end is inserted with a connecting tube, and one end of connecting tube is provided with fixture block, and fixture block is stuck in mounting groove, and the free end of connecting tube is provided with one
Extension tube, the center of the other end of piston only 1, which is provided with a screwed hole, the bottom centre of leather cup, is provided with a fastener,
One end that fastener is located in leather cup is provided with a swing handle, and the free end side wall of the fastener other end is provided with spiral shell
Line, fastener is by being threaded into screwed hole on the wall of side, along side wall ring to provided with some grooves on the wall of piston only side,
A cushion rubber is equipped with the groove of each piston only.Leather cup selection is the leather and fur products with corrosion resistance.
In use, due to the plugging action of leather cup so that outlet piston becomes more to facilitate when outlet
And outlet effect is more preferably, and more air can be filled under the premise of more labour-saving.
The utility model has the advantages and positive effects of：Due to using above-mentioned technical proposal so that user is to gas
The use of pipe becomes more to facilitate, and can be more laborsaving and be efficiently inflated, and operating efficiency is more efficient；And this practicality is new
Type has simple in construction, and easy to maintenance, processing cost is low, the advantages of operating efficiency is high.

Embodiment
As Figure 1-3, the utility model is a kind of dual fail-safe outlet piston, including piston only 1 and leather cup 2, piston
Body 1 is cylindrical structure, and the side wall of piston only 1 is provided with mounting groove 7, and one end of piston only 1 is inserted with a connecting tube
4, one end of connecting tube 4 is provided with fixture block 9, and fixture block 9 is stuck in mounting groove 7, and the free end of connecting tube 4 is provided with an extension tube 5, piston
The center of the other end of body 1, which is provided with a screwed hole 10, the bottom centre of leather cup 2, is provided with a fastener 8, fastener
8 one end being located in leather cup 2 are provided with a swing handle, and the free end side wall of the other end of fastener 8 is provided with screw thread, fastening
Device 8 is by being threaded into screwed hole 10 on the wall of side, along side wall ring to provided with some grooves on the side wall of piston only 1, respectively
A cushion rubber 6 is equipped with the groove of individual piston only 1.The selection of leather cup 2 is the leather and fur products with corrosion resistance.
In use, due to the plugging action of leather cup 2 so that outlet piston becomes more to facilitate when outlet
And outlet effect is more preferably, and more air can be filled under the premise of more labour-saving.
One embodiment of the present utility model is described in detail above, but the content is only of the present utility model
Preferred embodiment, it is impossible to be considered as being used to limit practical range of the present utility model.It is all to be made according to present utility model application scope
Equivalent change with improve etc., all should still belong within patent covering scope of the present utility model.
