Detailed description of the invention:
Embodiment: as shown in Figure 1 to Figure 2, this utility model provides the specific embodiment of a kind of medical air tool gas control equipment.Medical air tool gas control equipment in this embodiment, it is installed on cylinder (figure has no) outside, realize the selective lock to gas control equipment by the mechanical engagement between each parts, can lock when off working state, not lock time in working order.This gas control equipment includes that the gas of partial insertion cylinder controls plunger 1 and gas and controls plunger 1 and coordinate and control the switch base 2 of plunger 1 pressing plate 3 pivotally connected with switch base 2 for fixed gas and connect the self-lock switch 4 being arranged in pressing plate 3 slidably;Gas controls plunger 1 and is vertically arranged, it is column structure, and surface is provided with multiple flange coordinated with cylinder, by moving up and down the opening and closing controlling gas conveying, its upper end is located in horizontally disposed switch base 2 so that it is be limited to switch base 2 in the horizontal direction.This gas control equipment has off working state and duty, and when off working state, self-lock switch 4 locks, and self-lock switch 4 and gas control plunger 1 noncontact;Time in working order, self-lock switch 4 is opened, and self-lock switch 4 and gas control plunger 1 upper end and pushes against, i.e. gas controls the condition controlled in the effect of self-lock switch 4 of plunger 1 vertical direction.When gas control plunger 1 is pressed status, this medical air tool gas control equipment is open mode, it is not pressed down when gas controls plunger 1, then this medical air tool gas control equipment is closed mode, and medical air tool gas control equipment as shown in Figures 1 and 2 is closed mode.
As shown in Figure 3 and Figure 4, switch base 2 and pressing plate 3 are connected by pintle assembly 5, and pintle assembly 5 includes spring 51 and is positioned at the pair of rotary shafts 52 at spring 51 two ends.Rotary shaft 52 two ends are equipped with cylindrical bump, and each rotary shaft 52 is near bullet, and the cylindrical bump of one end of 51 is embedded in spring 51, and the cylindrical bump of the other end is embedded in pressing plate 3 and switch base 2.The present embodiment breaker in middle seat 2 is preferably notch cuttype, and upper step horizontal is provided with the first through hole 21 of a pair collecting rotary shaft, is positioned at downstairs and is positioned at the side of the first through hole 21 and is provided with and installs gas and control the second through hole 22 of plunger 1.Second through hole 22 can control plunger 1 for the gas of different model and arrange several, arranges three in the present embodiment.Pressing plate 3 is the direct functional unit of operator, and one end is provided with the trigger unit of press section 31, i.e. this gas control equipment, when needing to open this gas control equipment, only need to press at press section 31 after opening self-lock switch 4.Pressing plate 3 is additionally provided with the third through-hole 32 of a pair collecting rotary shaft 52.Therefore rotary shaft 52 cylindrical bump through penetrating third through-hole 32 again after the first through hole 21, and spring 51 is compressive state, and under the effect of spring 51, pintle assembly 5, switch base 2 and pressing plate 3 are for pushing against state.
As shown in Figure 5 to Figure 6, self-lock switch 4 lower surface is provided with projection 41, and projection 41 is symmetrically arranged on two with elastic arm 42, and elastic arm 42 top is provided with elastic arm projection 421.Pressing plate 3 is provided with the groove 33 coordinated with projection 41 and elastic arm 42, and groove 33 sidewall is provided with the draw-in groove 331 coordinated with elastic arm protruding 421.Groove 33 is similar to trapezium structure, and the distance between opposing sidewalls is turned left less and less, and the movement to elastic arm 42 has restriction effect.Snap in draw-in groove 331 when elastic arm 42 is moved to the left elastic arm projection 421, connecting firmly of self-lock switch 4 and pressing plate 3 can be realized, i.e. open self-lock switch 4.Self-lock switch 4 side is uniformly provided with some breach, and these breach have antiskid function, brings operation inconvenience when can prevent operator from opening or closing locking switch 4 because hands is sliding.
When installing this medical air tool gas control equipment, comprising the steps: first, projection 41 and the elastic arm 42 of self-lock switch 4 are placed in the groove 33 of pressing plate 3, now self-lock switch 4 can be close in pressing plate 3 move left and right.Then, by pintle assembly 5 to be located in the first through hole 21 and the third through-hole 22 of pressing plate 3 of switch base 2 simultaneously, switch base 2 is made to be connected with pressing plate 3, pressing plate 3 can do the rotation of certain angle with locking switch 4 with pintle assembly 5 for rotating shaft, owing to being spring 51 between two rotary shafts 52, under the effect of spring 51, pressing plate 3 in rotation process all the time by the constraint of pintle assembly 5.Finally, control gas, in the second through hole 22 that plunger 1 inserts switch base 2, to complete the installation of this medical air tool gas control equipment.
When using this medical air tool gas control equipment, self-lock switch 4 is moved to the left, make projection 41 be positioned at gas and control above plunger 1, in elastic arm 42 is moved to the left the draw-in groove 331 that elastic arm projection 421 snaps in pressing plate 3 simultaneously, elastic arm 42 under this state is deformed upon by the extruding of groove 33 sidewall, under elastic force effect, self-lock switch 4 and pressing plate 3 realize connecting firmly, during ensureing that pressing plate 3 rotates at pressing gas control plunger 1, pressing plate 3 is fixed with the relative position of self-lock switch 4, when i.e. operating this gas control equipment, only need to operate pressing plate 3.Pressing the press section 31 of pressing plate 3,41 times pressures of projection make gas control plunger 1 stress and move downward, open this gas control equipment, i.e. open cylinder and supply gas.Pneumatic tool uses complete, self-lock switch 4 is moved right, elastic arm 42 still with groove 33 sidewall for pushing against state, therefore self-lock switch 4 cannot be moved to the left voluntarily and open, i.e. self-lock switch 4 is in right positions the most all the time, even if pressing pressing plate 3, gas also cannot control plunger and press for 1 time, i.e. cannot open this gas control equipment, maloperation can be prevented effectively from.
The above is preferred implementation of the present utility model; it should be pointed out that, for those skilled in the art, on the premise of without departing from this utility model principle; can also make some improvements and modifications, these improvements and modifications are also considered as protection domain of the present utility model.
