Description

Full-automatic switch formula desk model sphygmomanometer

Technical field

This utility model relates to a kind of improvement of desk model sphygmomanometer, specifically a kind of full-automatic switch formula desk model sphygmomanometer.

Background technology

Present employed desk model sphygmomanometer, by box body, lid, glass tubing, hydrargyrum kettle and switch constitute, the glass tubing inner chamber is the mercury column chamber, open the lid during use, make the mercury column chamber vertical, open switch again, hydrargyrum in the hydrargyrum kettle is by flowing into bottom, mercury column chamber communicating pipe, its mercury column end face is on " 0 " position, can measure the blood pressure step, when buckling into lid in the box body after measuring blood pressure, need earlier mercury column chamber (promptly to hydrargyrum kettle direction) inclination miter angle to the right, after making mercury column return in the hydrargyrum kettle, close switch again, just can put down lid.The shortcoming of this desk model sphygmomanometer is: after 1, measuring blood pressure, operator often forget and close switch or forget that the inclination miter angle just puts down lid, hydrargyrum often spills from the vertical aperture of glass tubing, cause environmental pollution, minimizing because of hydrargyrum simultaneously also influences certainty of measurement, the blood pressure values of measuring is inaccurate, causes diagnostic error, influences patient's treatment; 2, operating procedure is many, uses inconvenience, and is easy to make mistakes, and causes error.Also the someone has designed some relevant desk model sphygmomanometer automatic interrupter schemes at present, but all needs the structure of desk model sphygmomanometer is done bigger change, so be difficult to promote to use.

Summary of the invention

It is a kind of when opening the lid that the purpose of this utility model is to provide, the switch of hydrargyrum kettle is opened immediately automatically, when putting down lid, but lid wing drop miter angle, and the switch of closing mercury kettle immediately, and do not need to change former desk model sphygmomanometer structure, easy to use, operation is time saving and energy saving, can avoid the full-automatic switch formula desk model sphygmomanometer that goes wrong.

For reaching above purpose, the technical scheme that this utility model adopted is: this full-automatic switch formula desk model sphygmomanometer, by box body, lid, glass tubing, hydrargyrum kettle and switch constitute, the glass tubing inner chamber is the mercury column chamber, the passage that communicates with the hydrargyrum kettle is established in the bottom, the turning cylinder and the lid of lid are fixed as one, at the fixing upper box cover tilting gearing of the left end of the turning cylinder of lid, when lid rotates when transferring, the lid tilting gearing forces lid (promptly to hydrargyrum kettle side) inclination miter angle to the right, establishes the switch gearing device in the bottom of lid, when lid rotates when transferring, the switch linkage also begins action, progressively close switch, when lid inclination miter angle, the switch Close All, continue to transfer lid this moment, lid can safe buckling in the box body.Described lid tilting gearing, by the rotational support plate, promote the arc sheet, 45 degree location retainings are turned round, rotational support plate return spring, promote pellet shot from a slingshot, pellet shot from a slingshot snaps in the cave and constitutes, the outer end, left side of the turning cylinder that is welded on lid that the staight shank end of promotion arc sheet is parallel with the mercury column chamber, make when lid rotates, promoting the arc sheet rotates synchronously, promoting pellet shot from a slingshot is located in the end wall that promotes the arc sheet, the upper edge of rotational support plate and the edge of front end are straight flange, bottom is the arc limit, axis hole is established in the rear end of top, and be enclosed within on the turning cylinder of lid, establish rotational support plate return spring in front end edge, the inboard, top of rotational support plate is established pellet shot from a slingshot with the corresponding position of promotion pellet shot from a slingshot and is snapped in the cave, when infra changes lid, driving promotion arc sheet rotates, because of being stuck in pellet shot from a slingshot, the promotion pellet shot from a slingshot snaps in the cave, so promoting arc sheet promotion rotational support plate rotates, so just push box body, lid is tilted, when lid changes miter angle down, the rotational support plate also changes 45 degree down, if continue to change down lid, because what 45 degree location retainings were turned round stops, the rotational support plate can not rotate again, firmly change lid this moment down, the promotion pellet shot from a slingshot snaps in the cave from pellet shot from a slingshot and skids off, lid is just put into box body, and the rotational support plate is return under the pulling force of rotational support plate return spring, and box body is set level, finish lid and rotate the action of transferring, when opening the lid, the rotational support plate is failure to actuate, when getting to the upright position, the promotion pellet shot from a slingshot snaps in pellet shot from a slingshot again and snaps in the cave, its rotational support plate return spring one end is fixed on rotational support plate front along the bottom, and the other end is fixed on the box side wall, and its 45 degree location retaining is turned round on the box body of the turning cylinder back lower place that is welded on lid; Described switch gearing device is by opening the pulling spring, close stay cord, angle pulley, the rope spring contracts, shift bar constitutes, opening pulling spring one end is fixed on the left comer of lid bottom, one end is connected with shift bar, closing stay cord one end is connected on the shift bar, the other end is walked around angle pulley and is connected with the rope spring that contracts, and angle pulley is located at right side, lid base, and the rope spring that contracts is fixed on the inner bottom part of box body, when the lid rotation is transferred, the rope spring that contracts is stretched earlier, and when lid changeed 30 degree angles down, the rope spring that contracts was pulled to the longest, when lid is rotated further when transferring, close just Drawing switch handle of stay cord, when under lid, forwarding miter angle to, the switch Close All, continue to change down lid, can buckle in the box body, when opening the lid, close stay cord and loosen, open the pulling spring and shrink, just the Drawing switch handle is opened switch automatically.

Advantage of the present utility model is: compare with the desk model sphygmomanometer of present use, switch is a full rotation type, as long as open the lid, switch is promptly opened automatically, transfer when buckling in the box body if lid rotated, then lid wing drop 45 is spent, and close switch synchronously, it is convenient especially to use, avoided closing switch or forgetting the hydrargyrum leakage that the inclination miter angle causes because of forgetting, in addition, this utility model need not to change the structure of former desk model sphygmomanometer, as long as add this two covering device, be beneficial to and apply.
