Abstract
The utility model discloses a floor drain plug fastening structure which is normally applied to a drainage device of a building. The floor drain plug fastening structure comprises a shaft (1), a plug (2), a spring (3) and a slotted axial blocking piece (4). When being applied to a forced sealed floor drain, the floor drain plug fastening structure mostly comprises the shaft for linkage of hydraulic power and mechanical force (or magnetic force), and the plug is arranged at the end of the shaft and is used for sealing the closed floor drain. According to a known structure, the plug is fixed at the end of the shaft through a bolt or a screw, but in the action course of the floor drain, the bolt or the screw for fixing the plug is likely to fall off when the plug is subjected to circumferential moment and axial impact. The fastening structure provided by the utility model adopts a spring structure, the slotted axial blocking piece replaces the bolt or the screw to fix the plug at the end of the shaft, and thus the problem of falling of the plug is solved.
Description
Technical field
The utility model relates to a kind of mechanical dewatering installation, and this device is discharged in sewer the ponding on ground, and prevents that the foul smell that gathers in sewer from overflowing.This device generally is used for the draining of building, is commonly called as floor drain.
Background technology
Floor drain is the building dewatering installation that generally uses, and generally is installed on flooring in building and the outfall place on ground, and excess surface water enters drainage pipe by floor drain, and floor drain mainly plays draining and prevents that the foul smell that gathers in drainage pipe from overflowing.For the foul smell that prevents from gathering in drainage pipe overflows, some have occurred in recent years and utilized mechanical force or magnetic force to realize the device of drainage channel forced sealing in floor drain.In these forced sealing floor drains, mostly include an axle that makes waterpower and mechanical force (or magnetic force) interlock, axle head is with obstruction, and stopping up the known features that is fixed in axle head is to fix with bolt or screw.When floor drain is in closed condition, by mechanical force or magnetic force, make the lower port close contact that stops up with the floor drain drainage channel, reach the purpose of sealing, with gas or the toy in isolated clog downstream drainage pipe.But due in the floor drain opening and in opening and closing state transformation, stop up and be subject to circumferencial direction moment and axial impact force, fixing bolt or the screw that stops up easily come off.For fear of bolt or toner screw, generally axle is made square shaft, when being subject to circumferencial direction moment to avoid stopping up, axle produces rotation and causes fixing bolt or the screw loosening that stops up.But this structure can't be eliminated the impact of axial impact force, and under long axial impact force effect, bolt or screw still can occur loosening and come off.
Summary of the invention
The purpose of this utility model is to provide a kind of fastening structure that adopts spring structure, uses the axial block piece of card slot type to replace bolt or screw, and axle head is fixed in obstruction, has solved the problem that comes off of stopping up.
The technical scheme that the utility model adopts is, with the axial block piece of card slot type and the fixing obstruction of spring.In the technical program, floor drain obstruction fastening structure is comprised of axle, obstruction, spring, the axial block piece of card slot type, between the shaft shoulder and the axial block piece of card slot type, place and stop up and spring, spring is in compressive state under the spatial constraints between the shaft shoulder and the axial block piece of card slot type.The shaft shoulder in the technical program can replace with the axial block piece of card slot type.Fig. 1 is structural representation of the present utility model, comprises axle (1), stops up (2), spring (3), the axial block piece of card slot type (4).Axle (1) is circular shaft in the diagram, but can be also other cross sectional shape, as square, hexagon etc.The shaft shoulder on axle (1) defines the position of obstruction (2), and axial trough defines the position of the axial block piece of card slot type (4).Stop up (2) and spring (3) between the shaft shoulder and the axial block piece of card slot type (4).In the technical program, the spatial constraints between the axial block piece of the shaft shoulder and card slot type (4) makes spring (3) be in compressive state, and the position near the shaft shoulder is fixed in obstruction (2) under the tension force of spring (3).The axial block piece of card slot type (4) can be the standard components such as shaft retaining ring, axle card, can be also the non-standard component of similar functions.
Operating principle of the present utility model is as follows:
Open and close in the state transformation process at floor drain, stop up (2) corresponding and move upward with axle (1) downwards.When floor drain was opened, water impact was stopped up (2), stopped up (2) and will be subject to circumferencial direction moment and axial force.When floor drain changes closed condition into by opening, stop up between (2) and floor drain housing external member (5) lower port and also can produce relative shock.These moments and axial force can be transmitted to the axial block piece of card slot type (4) by spring (3).Because the axial block piece of card slot type (4) may rotate when being subject to moment, but can not break away from axial trough; The axial block piece of card slot type (4) can not break away from axial trough when being subject to axial force yet.Therefore, structure of the present utility model has ensured that obstruction (2) can not come off.
