Description
Technical field
The utility model relates to a kind of accessory of hand-pulled inflator, particularly relates to a kind of hand-pulled inflator handle, and this handle is suitable for the hand-pulled inflator of energy bidirectional inflating very much.
Background technique
Current hand-pulled inflator (being also gas-filled pump) kind is quite a lot of, tradition hand-pulled inflator comprises the body with a tubular, be assembled with a piston operated by connecting rod in the body, the all sides of piston are provided with to recessed rubber cup, and the handle be provided with in connecting rod top for user's handling, extend a gas tube in body lower end.During user's pull-up handle, air can enter below the piston inside body, when handle presses down by user, then can push in gas tube by the air in body by piston, provide and once inflate.The hand-pulled inflator of this kind of traditional type is unidirectional hand-pulled inflator, namely moves up and down in a round trip at piston, and be merely able to have single stroke to provide aeration, utilization efficiency is lower.
Once see another kind of more progressive gas-filled pump on the market, it can push away at handle, and drew in two-way travel and all carry out inflation action, and improve utilization efficiency.As the Chinese utility model patent " two-way inflating pump " that the patent No. is ZL00255072.5 (notification number is CN2450405Y), the patent No. is the Chinese utility model patent " two-way inflating pump " of ZL00255072.5 (notification number is CN2450405Y), and the patent No. is the Chinese utility model patent " a kind of two-way inflating pump " of ZL200620100394.9 (notification number is CN2874057Y), they all disclose the gas-filled pump of energy bidirectional inflating.
No matter above which kind of two-way inflating pump, it does not all arrange pressure gauge on handle, needs additionally to arrange configuration pressure gauge as wanted Real-Time Monitoring inflation pressure, pressure gauge and hand-pulled inflator are two individual components, pressure gauge may leave behind, and easily loses, and uses inconvenience.
Also the hand-pulled inflator handle had with pressure gauge, but draws gas-entered passageway and directly communicates with the gas-entered passageway in handle, and some impurity strengthened enter in hand-pulled inflator as fine sand is also easy from suction port, affect the use of inflator.
In sum, manometric hand-pulled inflator handle also can be further improved existing generation.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of band manometric hand-pulled inflator handle, and this handle effectively can be stopped impurity and enter pump inside via suction port.
The utility model solves the problems of the technologies described above adopted technological scheme: the manometric hand-pulled inflator handle of a kind of band, comprise handle body, the lower central position of handle body is provided with the endoporus connected for interior pipe inserting and the exit orifice connected for outer tube inserting, described endoporus forms outlet passageway, space between endoporus and exit orifice forms gas-entered passageway, the top of handle body has cavity, be provided with pressure gauge in cavity, manometric pressure sensitive end communicates with described endoporus through the bottom surface of cavity; It is characterized in that: the side of described handle body center is provided with the air outlet be communicated with described endoporus; The opposite side of described handle body center is provided with the suction port be communicated with described cavity, filter screen is provided with in described cavity, filter screen covers in described suction port, the underrun of cavity has the inlet hole being communicated with cavity and described gas-entered passageway, and described gas-entered passageway is in communication with the outside via inlet hole, filter screen and suction port.
The central position of above-mentioned cavity bottom surface is provided with the attachment hole communicated with endoporus, and this attachment hole is tapped hole, and manometric bottom has the post that is threaded to downward-extension, described in the male screw that is threaded be connected in described attachment hole.Filter screen uses for a long time and has dust and overstock, and affects the ventilatory effect of filter screen, this structure convenient assembling and disassembling pressure gauge, due to pressure gauge convenient assembling and disassembling, also just convenient cleaning or change filter screen, ensure gas-entered passageway and the external world unimpeded.
Above-mentioned manometric top has annular shoulder block portion, and filter screen is circular and is set in the periphery of pressure gauge bottom, and filter screen is compressed between described annular shoulder block portion and the bottom surface of cavity.Filter screen, to the effect of filter screen Constrained, is better fixed by annular shoulder block portion.
For ease of connecting, the perisporium of above-mentioned suction port and air outlet is provided with in order to the spiral chute with gas-tpe fitting clamping.When gas-tpe fitting is connected with air outlet, being now inflated condition, is then exhaust condition when gas-tpe fitting is connected with suction port.
The bottom of above-mentioned manometric shell has the perforation of the pressure sensitive end being communicated with endoporus and Qi Nei.Pressure sensitive end just can be arranged in pressure gauge housing, to play the effect of protection pressure sensitive end.
The inner hole wall of above-mentioned endoporus is provided with the shoulder block portion in order to internal pipe gear.The internal pipe in shoulder block portion indicative function is installed, conflicting when interior pipe and shoulder block portion shows that interior pipe is in place.
For convenience of installing on outer tube by handle, the inner hole wall of above-mentioned exit orifice is provided with the internal thread with connecting for external pipe thread.
Compared with prior art, the utility model has the advantage of: manometric pressure sensitive end is communicated with endoporus, and air outlet is communicated with inflatable product, therefore this pressure gauge accurately can read the air pressure inside of inflatable product, pressure gauge and handle body are structure as a whole, pressure gauge, just as a part for handle body, is just not easily lost in using process, is facilitated Real-Time Monitoring inflation pressure simultaneously; Gas-entered passageway in handle does not directly communicate with between suction port, but is in communication with the outside via filter screen, and filter screen not only plays the effect of air inlet, also plays the effect of impurity screening, effectively prevents impurity from entering in inflator.
