Abstract

The utility model relates to the technical field of an instrument, particularly a rotary damping wing panel with the function of automatic expansion installed on a restricted rotation type material level controller (also called restricted rotation type material surface annunciator). The utility model is composed of a wing handle shaft, two wing panels, steel balls, springs, screw plugs, etc., wherein, the two wing panels can be rotated and stacked together and can automatically expand so that the connection between the restricted rotation type material level controller and a silo container can be changed into the connection in a pipe screw thread type, which provides conditions for small volume, light weight, low cost and easy assembly and disassembly for the controller. Simultaneously, the two wing panels of the utility model are in symmetric distribution with smooth rotation, which comparatively extends the service life of the restricted rotation type material surface controller. The width of each of the two wing panel can be designed according to the size of a pipe screw thread, and the length can be changed as required.

Description

Rotary damping wing panel with the function of automatic developing

The utility model relates to field of instrumentation technology, particularly a kind of gyrodamping fin that can launch automatically that (also claims blocking rotary type charge level signalling device, blocking rotary type level-sensing device) on the blocking rotary type charge level controller.

At present both at home and abroad the damping fin on the blocking rotary type charge level controller that uses is fixed, has single-blade, double-vane, four wings fixed as what U.S. thatch Nitor produced; Japan Toko Bussdan Co., Ltd. be that double-vane is fixed, these blocking rotary type charge level controllers, because of being subjected to the restriction of damping fin physical dimension, make itself and being connected of storage bin container mostly be the flange mode, thereby cause the big body weight of blocking rotary type charge level controller shape, high again, the loading and unloading inconvenience of cost.For this reason, the damping fin of the blocking rotary type charge level controller that U.S. thatch Nitor and Shanghai Automatic Instrument and Meter Factory No.5 produce just adopts the big knife-edge of single-blade fixed, changes charge level controller and being connected of storage bin container into screw-type.But such charge level controller is the one-sided distribution of single-blade because of the damping fin, and rotation is got up not steady, will inevitably shorten the serviceable life of charge level controller.

The utility model is intended to overcome the defective of above-mentioned prior art, for the blocking rotary type charge level controller a kind of novel structure is provided, make simple, easy to loading and unloading, the gyrodamping fin that can launch automatically.

For achieving the above object, the utility model is to be made of wing arbor, fin, steel ball, spring and plug etc.Wing arbor is hollow, the flat fork of groove milling in the middle of the one end is provided with, flat stick adorning two with two pins can rotating fin, an end of fin is circular-arc.The other end the inside car of wing arbor has screw thread, also is provided with a pin-and-hole.After in wing arbor hollow, a steel ball, a spring being housed, refill a plug.Screw plug, spring is pressed just to produce an axial force, promotes two fins by steel ball around pin revolution and launch, until two fins and wing arbor in vertical state.

The utility model compared with prior art advantage is a lot: two fins can turn round folded and can launch automatically again together, thereby got rid of the structure that blocking rotary type charge level controller and storage bin container must take the flange to be connected, what replace is the pipe thread connected mode, and this is blocking rotary type charge level controller reduced volume, weight reduction, reduces cost and created advantage.Two fins of the present utility model are symmetrical distribution, rotation steadily, stressed evenly, no impact shock has prolonged serviceable life of blocking rotary type charge level controller relatively.The width of two fins of the present utility model can be by the size design in a kind of pipe thread hole, and its length can change as required.The on-the-spot installation and removal of the utility model all make things convenient for.

Accompanying drawing is a structural representation of the present utility model.

Below in conjunction with accompanying drawing, further set forth embodiment of the present utility model.

Referring to accompanying drawing, the utility model is by hollow wing arbor 1, formations such as fin 7, steel ball 5, spring 4 and plug 3.The flat fork of groove milling in the middle of an end of wing arbor 1 is provided with, flat stick adorning two with two pins 6 can rotating fin 7, an end of fin 7 is circular-arc.The other end the inside car of wing arbor 1 has screw thread, also is provided with a pin-and-hole 2.After in wing arbor 1 hollow, steel ball 5, spring 4 being housed, refill a plug 3.

Tighten plug 3, spring 4 is compressed and just produces an axial force, promote the arc sections of two fins 7 by steel ball 5, two fins 7 are launched around pin 6 opposing revolutions respectively, until two fins 7 and wing arbor 1 in vertical state, two fins 7 are because of being subjected to the spacing stop of wing arbor 1 side.Two fins, 7 turning courses, the arc surface on the fin 7 contacts with steel ball all the time.When giving two fins 7 to closing up direction when applying torque, two fins 7 just turn round and folded and together around pin 6 respectively in opposite directions, are parastate with wing arbor 1.This moment, the circular arc position of two fins 7 made steel ball 5 produce an axial displacement, make spring 4 be compressed a corresponding displacement again, thereby the spring force that produces acted on two fins 7 again.When the external torque that applies disappears, two fins 7 are just under the effect of spring force and be expanded to extreme position automatically.During installation, earlier the bull stick of wing arbor 1 with the blocking rotary type charge level controller joined by pin-and-hole 2, with hand two fins 7 are closed up foldedly and together again, just launch automatically after making it pass threaded hole on the storage bin container sidewall, threaded connector is tightened got final product then.During dismounting, unclamp threaded connector after, as long as slightly firmly can make it withdraw from threaded hole outward once drawing.

The utility model is on probation in Liaoning Province Liaoyang Automatic Instrument Metre Factory, and effect is very good.
