Description

Inflating device with screw inflating head
Technical Field
The present invention relates to a pump, and more particularly to a pump with a rotatable pump head detachably coupled to an air nozzle by a screw operation.
Background
Referring to fig. 1, the conventional inflator 1 is a device 1, the device 1 may be connected to an air faucet 11, and includes a gas supply mechanism 12, and an inflation head 10 combined with the gas supply mechanism 12, the gas supply mechanism 12 includes an inner cylinder 121 defining a chamber 120, an outer cylinder 122 capable of reciprocating along an axis with respect to the inner cylinder 121, and a gas cylinder 124 installed in the chamber 120 of the inner cylinder 121, the gas cylinder 124 stores gas therein, and has a bottle mouth 125 capable of being punctured.
The inflation head 10 includes a base 13 axially coupled to the inner cylinder 121, the base 13 having a first annular wall 132 defining a first channel 131, and a second annular wall 134 defining a second channel 133, the second channel 133 being in communication with the first channel 131, and the second annular wall 134 having an external thread 135 surrounding the second channel 133. The inflation head 10 further includes an inflation switch 14 mounted at the first channel 131 of the base 13, a piercing member 15 capable of piercing the mouth portion 125 of the gas cylinder 124, a clamping ring 16 mounted in the second channel 133, a push ring 17 axially abutting against the clamping ring 16, and a clamping nut 18 screwed at the external thread 135 of the base 13.
After the air faucet 11 sequentially penetrates the tightening nut 18, the pushing ring 17 and the clamping ring 16, the tightening nut 18 is screwed, so that the pushing ring 17 is pushed to press the clamping ring 16, and the clamping ring 16 is forced to expand and deform inward to clamp the air faucet 11. When the inflation switch 14 opens the flow passage between the first passage 131 and the second passage 133, the gas stored in the gas cylinder 124 can flow toward the gas nozzle 11 for inflation. Since the improvement of the present invention is independent of how the gas supply mechanism 12 is manually inflated and how the inflation switch 14 operates, the structure and operation of the aforementioned components will not be described in detail.
Although the purpose of connecting or separating with the air nozzle 11 can be achieved by rotating the packing nut 18 in the existing inflating device 1, the existing inflating device 1 is usually very close to the object to be filled, for example, for inflating a tire, the inflating head 10 must be inserted into the air nozzle 11 of the tire, and because there are steel bars or wheel rim covers and other objects around the air nozzle 11 of the tire, the packing nut 18 cannot be too large in design, and when the packing nut 18 is rotated after being inserted, the application of force is not easy and the operation is also inconvenient. In addition, it is very laborious to rotate the tightening nut 18 with a small volume to press the push ring 17 to deform the clamp ring 16. When the tightening force of the tightening nut 18 is insufficient, the problems of air leakage and inaccurate inflation are also easily caused.
