Abstract
The utility model provides a sliding block type moment limiter, comprising an arched plate, a pulling plate which is fixedly arranged on the arched plate and a limiter body which is fixed on the pulling plate by fastening screws. A micro-switch and a sliding rod is fixedly arranged in the limiter body; one side of the micro-switch is provided with a micro-switch small wheel; the sliding rod penetrates through the limiter body and the two ends thereof are arranged at the outer side of the limiter body; a positioning baffle ring is arranged between the front end of the sliding rod and the limiter body; a return spring is arranged between the rear end of the sliding block and the limiter body; an adjustable sliding block is arranged at the middle of the sliding block by screw threads; a part of the inner side of the adjustable sliding block is an inclined surface which is contacted with the micro-switch small wheel; and the tail end of the sliding rod is provided with a screwdriver edge. The utility model adopts a sliding block type inclined surface structure, thoroughly relieves the function of external force to the micro-switch, really leads the micro-switch not to be damaged due to the function of external force, and has simple structure, low manufacture cost, convenient installation and simple and convenient debugging.
Description
Technical field
The utility model relates to mechanical field, relates in particular to a kind of slide block type limiter of moment.
Background technology
In the background technology, the patent No. is in the patented technology of " 012623628 ", a kind of push-down moment control device is disclosed, this device comprises push rod device and micromatic setting, push rod device is made up of push rod, retainer spring, slider, pull back spring, micromatic setting is made up of micro-switch seat, micro-switch, positioning wire spring, micrometer adjusting screw, though this device has solved perishable, the damageable problem of traditional moment control device, but still having the damageable hidden danger of switch, structure is shortcomings such as complexity, cost of manufacture height comparatively.
Summary of the invention
The utility model provides a kind of slide block type limiter of moment, has solved existing torque controller and has had the shortcoming that the damageable hidden danger of switch, structure are comparatively complicated, cost of manufacture is high.
The technical solution of the utility model is achieved in that the slide block type limiter of moment, comprise the bow plate, be fixedly mounted on bow on the plate arm-tie and be fixed on body on the arm-tie with tightening screw, the body internal fixation is equipped with micro-switch, slide bar, micro-switch one side is established the micro-switch steamboat, slide bar passes body, two ends are positioned at the body outside, be provided with positioning retainer ring between slide bar front end and the body, be provided with pull back spring between rear end and the body, be equipped with adjustable skid by screw thread in the middle of the slide bar, the inboard part of adjustable skid is the inclined-plane, and the inclined-plane contacts with the micro-switch steamboat, and the slide bar tail end is provided with the spiral shell edge of a knife;
Establish fixing slide carriage in the body, fixing slide carriage is provided with slideway, and adjustable skid is satisfied with in the slideway;
The adjustable skid bevel altitude is less than or equal to the stroke height of micro-switch.
The beneficial effects of the utility model are: the utility model has adopted the slide block type ramp structure, thoroughly removes the effect of external force to micro-switch, really makes micro-switch no longer because of damaged by the external force effect, simple in structure, cost of manufacture is low, and is easy for installation, debugs easy.
Description of drawings
Fig. 1 is the utility model structural representation.
Part explanation: 1, body, 2, slide bar, 3, adjustable skid, 4, fixing slide carriage, 5, pull back spring, 6, micro-switch, 7, the bow plate, 8, positioning retainer ring, 9, arm-tie, 10, the micro-switch steamboat, 11, the spiral shell edge of a knife, 12, tightening screw.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described: the slide block type limiter of moment; comprise body 1; be cavity in the body 1; two parts are integral by screw retention up and down; play the effect of sealing and dustproof waterproof and protection interior arrangement; establish two micro-switchs 6 in the body 1; micro-switch 6 one sides are established micro-switch steamboat 10; if two slide bars 2; slide bar 2 passes body 1; two ends are positioned at body 1 outside; can move forward and backward; set position back-up ring 8 between slide bar 2 front ends and the body 1; establish pull back spring 5 between the other end and the body 1; establish adjustable skid 3 in the middle of the slide bar 2; adjustable skid 3 is threaded with slide bar 2 usefulness; slide bar 2 tail ends are established the spiral shell edge of a knife 11; an interior side part of adjustable skid 3 is an inclined-plane; the inclined-plane contacts with micro-switch steamboat 10; if arm-tie 9, arm-tie 9 one ends are connected with bow plate 7, captive joint with body 1 by tightening screw 12 simultaneously; also be provided with fixing slide carriage 4 in the body 1; fixing slide carriage 4 is provided with slideway, and adjustable skid 3 is satisfied with in the slideway, when the spiral shell edge of a knife 11 that turns slide bar 2 tail ends; adjustable skid 3 can move front and back on slide bar 2; play the fine setting effect, when bow plate 1 stressed deforming, bow plate 1 one sides bow plate pulling arm-tie 9 moves forward; opposite side bow plate promotes slide bar 2 and moves backward; micro-switch steamboat 10 is moved along the inclined-plane of adjustable skid 3, force micro-switch 6 actions, to cut off or energized; report to the police for tower machine operation person or make tower machine suspension hook stop to full secure side playing the safety control effect to motion.After micro-switch 6 has been worked, slide bar 2 also need continue to move backward, micro-switch steamboat 10 can slip over adjustable skid 3 whole inclined-planes at this moment, enter the plane parallel, thereby thoroughly remove the effect of external force, really make it micro-switch 6 no longer because of damaged by the external force effect to micro-switch 6 with micro-switch 6, simple in structure, make easily, easy for installation, debug easy.
