A kind of keg float position regulation and fixed structure based on worm structure
Technical field
The utility model relates to bathroom accessory field, particularly a kind of keg float position regulation and fixed structure based on worm structure that is applicable to inlet valve, feeder or drain valve.
Background technique
The drain valve of existing inlet valve or feeder and minority, the up-down adjustment of keg float is to realize by worm structure: keg float and adjustable lever have the screw thread of identical pitch, and during the turn adjustable lever, keg float can produce relative moving up and down at adjustable lever.Though such structure keg float can be easily in adjustable lever up-down adjustment position, but because screw-thread fit needs can screw freely, in transportation process, because factors such as impact and vibrations, cause adjustable lever on keg float, to occur own rotation phenomenon easily, the position of prior setting is changed, thereby have influence on the setting value of keg float working position.
In addition, also have on above scheme in addition improvedly, for example below screw thread on the keg float, increase by a fixing salient point, recessing on the adjustable lever screw thread, when the salient point of keg float screw thread rotated in the screw thread fluting of adjustable lever, adjustable lever will rotate the certain torsion of needs again.Though such structure can solve the adjustable lever phenomenon that easy appearance oneself is rotated on keg float, have following shortcoming: 1, use electric screw driver in process of production and fast adjustable lever is screwed in the keg float, salient point is easy to be worn down to does not have amount of interference to cause losing efficacy.Can influence manufacturing efficiency again if speed is low.2, for the operator can regulate the keg float height more easily, the amount of interference of salient point and groove generally is not very big, so some loosening positioning phenomenon can occur in transportation or falling process.3, because the groove on the adjustable lever is 180 ° one, so the minimal adjustment height is 1/2 pitch.Can not realize littler fine setting.
The model utility content
Main purpose of the present utility model is to overcome keg float of the prior art in transportation or working procedure, because screw rod oneself rotates the shortcoming that the positioning phenomenon takes place easily on keg float, proposes a kind of keg float position regulation and fixed structure based on worm structure.
The utility model adopts following technological scheme:
A kind of keg float position regulation and fixed structure based on worm structure, comprise keg float with mounting hole and be arranged in the screw rod of regulating the keg float position in the mounting hole, it is characterized in that: also include to be arranged at and prevent the assembly that screw rod rotates relative to keg float between keg float and the screw rod.
Further, described assembly comprise be fixed in the fixed block on the described mounting hole and be formed at keg float and described screw rod between resistor, this fixed block has the through hole that passes for described screw rod.
Further, described keg float mounting hole is provided with internal thread and is connected with described screw flight.
Further, described fixed block is provided with internal thread and is connected with described screw flight.
Further, described resistor is the elasticity salient point that is formed in described fixed block or the described keg float mounting hole, and described screw rod is provided with the draw-in groove suitable with this elasticity salient point.
Further, described draw-in groove is the draw-in groove that arranges along described spiro rod length direction.
Further, described resistor is rubber ring, and described keg float is provided with the groove that holds this rubber ring.
Further, the described fixed block outside is provided with Elastic buckle spare, and described keg float mounting hole extends internally and is formed with the catching groove suitable with this Elastic buckle spare.
By above-mentioned to description of the present utility model as can be known, compared with prior art, the utlity model has following beneficial effect:
A kind of keg float position regulation and fixed structure based on worm structure of the present utility model, basis in existing keg float and screw rod linkage structure has increased fixed block, between keg float and screw rod, also be provided with resistor, screw rod is threaded with keg float or fixed block, and resistor can be rubber ring or be formed at the interior elasticity salient point of fixed block.Specifically comprise following several implementation: when screw rod is threaded with fixed block, resistor is formed at the elasticity salient point in fixed block through hole or the keg float mounting hole, earlier fixed block is pressed in the keg float mounting hole, with pneumatic rotary device screw rod is screwed in keg float fast to desired location again, behind the screw-in, the elasticity salient point need be overcome the frictional force of elasticity salient point and draw-in groove because elasticity does not polish when screw rod will rotate, so just make screw rod own rotation phenomenon can not occur on keg float.When needs were regulated the keg float upper-lower position again, the turn screw rod can also have certain shift feeling because of the effect of elasticity salient point.
When keg float is connected with screw flight and resistor when being the elasticity salient point that is formed in the fixed block through hole, earlier fixed block was inserted in the screw rod along elasticity salient point and cooperating of screw rod draw-in groove, with pneumatic rotary device screw rod is screwed in the keg float mounting hole fast to desired location again, behind the screw-in, fixed block then is pressed into keg float with fixed block again because can the elasticity salient point can be ground to along with screw rod rotates.Need overcome the frictional force of elasticity salient point and draw-in groove when screw rod will rotate, so just make screw rod on keg float, own rotation phenomenon can not occur.When needs were regulated the keg float upper-lower position again, the turn screw rod can also have certain shift feeling because of the effect of elasticity salient point.
When keg float is connected with screw flight and resistor when being the elastic ring that is arranged between screw rod and the fixed block, earlier fixed block and rubber ring are inserted in the screw rod, with pneumatic rotary device screw rod is screwed in fast again and arrive desired location in the keg float mounting hole, then again fixed block is pressed into keg float and makes rubber ring be closed in the groove.Need overcome the frictional force of rubber ring and keg float when screw rod will rotate, so just make screw rod on keg float, own rotation phenomenon can not occur.When needs were regulated the keg float upper-lower position again, directly the turn screw rod got final product.
