According to the novel flow adjusting mechanism, a novel gear structure which is formed through the steel ball and the spring is simple in design and easy to install and enables the air inflow machining to be simplified and the costs to be greatly reduced.
Description
Technical field
The utility model relates to a kind of Novel flow rate controlling mechanism.
Background technique
At present, pneumatic tool regulates the running speed of air chamber rotor mostly by controlling the mode of gas flow size, but existing flow control device great majority all adopt gear pad, corrugated gasket, locating washer, by the groove on corrugated gasket and the projection two-phase snap-fit secured adjusted button on locating washer and the relative position of air input joint, thereby change gas-entered passageway and enter the gas flow in pneumatic tool air chamber, to reach the object that changes rotor running speed, but the shift feeling that this flow control device produces overall structure is not strong, and this design makes the processed complex of air input joint, not only increased cost, also be not easy to install.
Summary of the invention
The utility model will solve existing flow control device because the cause of design causes shift feeling strong and make the technical problem of the processed complex of air input joint.
The technical scheme in the invention for solving the above technical problem is:
The utility model discloses a kind of Novel flow rate controlling mechanism, comprise air input joint, air input joint one end is connected with sleeve, the other end is connected with stem, air-flow path in air input joint is divided into gas-entered passageway and the outlet passageway invariably connecting mutually, stem is provided with the suction port connecting with gas-entered passageway and the air outlet connecting with outlet passageway, it is characterized in that: described suction port and air outlet are all arranged on stem outside; Described air input joint is arranged with adjusting knob outward; Described adjusting knob inner side is provided with a ring-shaped step, and ring-shaped step is provided with some grooves; Described sleeve is provided with a spring groove with respect to ring-shaped step one end; One spring is stuck in spring groove; Between described spring and ring-shaped step, be provided with a steel ball.
On described adjusting knob, have a body of rod, the internal diameter of the body of rod and the external diameter of stem match; On the described body of rod, have a breach, this breach can expose air outlet completely; Described suction port is not in the coverage area of the body of rod; Breach edge is waveform.
The beneficial effects of the utility model are:
Compared with prior art, adopt the Novel flow rate controlling mechanism of the utility model structure, utilize steel ball and spring to form a novel shift structure, this shift structure simplicity of design, install easily, make air input joint simplified processing, reduced greatly cost, and the feel of the shift feeling that produces of this shift structure while strongly more fitting practice.

Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
Refer to Fig. 1 to Fig. 3, the utility model provides a kind of Novel flow rate controlling mechanism, comprise air input joint (1), air input joint (1) one end is connected with sleeve (2), the other end is connected with stem (3), air-flow path in air input joint (1) is divided into gas-entered passageway and the outlet passageway invariably connecting mutually, stem (3) is provided with the suction port (4) connecting with gas-entered passageway and the air outlet (5) connecting with outlet passageway, and described suction port (4) and air outlet (5) are all arranged on stem (3) outside; The outer adjusting knob (6) that is arranged with of described air input joint (1); Described adjusting knob (6) inner side is provided with a ring-shaped step (7), and ring-shaped step (7) is provided with some grooves (8); Described sleeve (2) is provided with a spring groove (9) with respect to ring-shaped step (7) one end; One spring (10) is stuck in spring groove (9); Between described spring (10) and ring-shaped step (7), be provided with a steel ball (11).
On described adjusting knob (6), have a body of rod (12), the external diameter of the internal diameter of the body of rod (12) and stem (3) matches; On the described body of rod (12), have a breach (13), this breach (13) can expose air outlet (5) completely; Described suction port (4) is not in the coverage area of the body of rod (12); Breach (13) edge is waveform.
When air-flow enters from sleeve openings (14), the outlet passageway of flowing through in air input joint (1), because outlet passageway is not communicated with gas-entered passageway, so air-flow is (5) outflow from air outlet, air-flow enters gas-entered passageway from suction port (4) again, some passes stem (3) from adjusting knob, the ring-shaped step upper groove (8) of adjusting knob inner side be take adjusting knob (6) center and is circularly and evenly distributed as benchmark, described groove (8) is arc groove, gear is fixedly time, steel ball (11) is against spring (10) and groove (8) surface simultaneously, when needs regulation stall, rotation adjusting knob (6), utilize the elastic force of spring (10), steel ball (11) starts to roll, in groove originally, move in adjacent side groove or other groove, select as required groove to determine gear, in the time of in steel ball (11) embeds groove (8), can produce strong shift feeling, in regulation stall, therefore the size of flow also changes, because the rotation of adjusting knob (6) can drive the body of rod (12), the athletic meeting of the body of rod (12) changes the area of air outlet (5), and suction port (4) is not in the coverage area of the body of rod (12), so when air outlet (5) area changes, the size of gas flow also changes thereupon, so only need change air outlet (5) area with regard to controllable flow rate size, thereby regulate the running speed of pneumatic tool air chamber rotor.
The utility model utilizes steel ball and spring to form a novel shift structure, this shift structure simplicity of design, installs easily, makes air input joint simplified processing, reduced greatly cost, and the feel of the shift feeling that produces of this shift structure while strongly more fitting practice.
