Abstract

The utility model discloses a lifting device for a side pressing type water tank drain valve. Two rotatable lifting arms are mounted at the bottom of an H-shaped brace, a spiral shaft sleeve forming a revolute pair with the lifting arm is mounted on each lifting arm, the shaft sleeve is matched and connected with the threads of an extended screw, a pushing screw enables the lifting arms to swing upward, a support part in a direction in parallel to and on the same side with the two lifting arms is arranged below the two top ends of the H-shaped brace, and the support part is connected with the vertical arms on the two sides of the H-shaped brace; due to the arrangement of the support part between the inner wall of the water tank and the H-shaped brace, the H-shaped brace is stressed uniformly, so that the lifting arms fail to reach a certain extent due to the deviation of the lower part of the H-shaped brace during screw pressing work, namely, when a full-drain pull rod is pulled, a half-drain pull rod fails to reach a proper place, and the full-drain and the half-drain control functions of the drain valve fail.

Description

Side is by the lifting appliance of formula water tank drain valve

Technical field

The utility model relates to the full row of draining valve, partly arranges the control device of pull bar, and particularly a kind of side is by the lifting appliance of formula water tank drain valve.

Background technology

Existing by lifting full row, partly arranging the full row of pull bar control draining valve, the hoisting mechanism of half drain function, its generally outstanding top that is connected in the water tank, the support of hoisting mechanism only two ends, top and water tank is connected and fixed, pressing keys drives the carry arm lifting, rotation is moved and is lifted full row, partly arranges pull bar on the carry arm, realizes the full row and half drain function of draining valve; The support stress point of hoisting mechanism only is 2 points that its top is connected with water tank, when the interlock axle sleeve lateral pressure of frame bottom, promptly produce torsion at a top of the trellis tie point, because frame bottom does not form firm annexation with water tank, therefore this lateral pressure can make the support bottom because of the stressed angle that is offset, this skew can damage hoisting mechanism (the top tie point is easily twisted off), and when the angle of the stressed swing in support bottom is big, also can influence the last amplitude of oscillation degree of carry arm, be that the carry arm of hoisting mechanism can't normally lift the full row on the draining valve, partly arrange pull bar, the full row of draining valve and half draining control disabler.

The utility model content

For addressing the above problem, the utility model is intended to propose the lifting appliance of a kind of side by the formula water tank drain valve.

The technical scheme that its technical problem that solves the utility model adopts is: side is by the lifting appliance of formula water tank drain valve, two rotating carry arms are installed on H type frame bottom, spiral sleeve with its formation revolute pair is installed on each carry arm, axle sleeve is connected with the lengthening screw flight, pushing screw rod can make on the carry arm and put, it is characterized in that: below two tops of H type support, be provided with support member on the direction of and homonymy parallel with two carry arms, support member is connected with the vertical arm of H type support both sides.

The vertical arm top that H type support of the present utility model is two is provided with band inserted block integrated with it, the inserted block side is provided with elasticity button bar integrated with it, the convex edge on the inserted block plug together with parallel slot geosynclinal block, be provided with the button hole that is communicated with it at the parallel slot side, the spacing block set on the button bar cooperates screens to be connected with button hole; The geosynclinal block top is provided with screw, by screw geosynclinal block is mounted on the water tank inner top, and the snapping that plugs together by inserted block and geosynclinal block, and the two vertical arm tops of realizing H type support are with the fast quick-detach of geosynclinal block or be connected.Support member of the present utility model is a push rod, and push rod one end and vertical arm plug together affixed, and the push rod other end is provided with the cross profile shaft, and the cross axis hole on cross profile shaft and the tank inner wall plugs together affixed; Then can realize being connected between H type support bottom and the water tank, make to push to make when putting on the carry arm that H type support is not because of the support of support member produces skew, make that amplitude of oscillation degree does not produce error on the carry arm at screw rod.Support member of the present utility model also can be horizontal shore, a side is provided with two fixture blocks on the horizontal shore, fixture block touches with the bottom screens of vertical arm, the opposite side of horizontal shore is provided with the fixed head that can be installed on the tank inner wall, and the design of the vertical arm of H type support at this moment can extend or extend to the fixture block on the horizontal shore.

The beneficial effects of the utility model are: by between tank inner wall and H type support the installation support member being set, make H type support whole stressed even, the skew of H type support bottom causes putting on the carry arm amplitude that do not reach when avoiding screw rod to push work, promptly lift full row, partly arrange pull bar and do not reach the position, the full row of draining valve and half draining control disabler.
